CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS

        Matters discussed in this document may constitute forward-looking statements within the meaning of Section 27A of the U.S. Securities Act of 1933 (the "U.S. Securities Act"), and Section 21E of the U.S. Securities Exchange Act of 1934 (the "U.S. Exchange Act").

Risks Relating to Business Operations in Emerging Markets

Emerging markets such as the Russian Federation, Ukraine and other CIS countries are subject to greater risks than more developed markets, including significant legal, economic, social, regulatory, tax and political risks.

        Investors in emerging markets such as the Russian Federation, Armenia, Ukraine, Turkmenistan, Belarus and other CIS countries should be aware that these markets are subject to greater risk than more developed markets, including in some cases, significant legal, economic, social, regulatory, tax and political risks. Investors should also note that emerging economies such as the economies of the Russian Federation, Ukraine and other CIS countries are subject to rapid change and that the information set out herein may become outdated relatively quickly.

        There is a number of risks associated with investing in emerging markets, including the following:

•

instability of emerging markets (for more information, see "—Risks Relating to Economic Risks in Our Countries of Operation" and "—Legal Risks and Uncertainties");



•

high volatility of national currencies (for more information, see "—Risks Relating to our Financial Condition");



•

possible geopolitical disputes (for more information, see "—Political and Social Risks"); and



•

possible liquidity constraints (for more information, see "—Risks Relating to Economic Risks in Our Countries of Operation" and "—Risks Relating to our Financial Condition").

        Accordingly, investors should exercise particular care in evaluating the risks involved and must decide for themselves whether, in light of those risks, their investment is appropriate. Generally, investment in emerging markets is suitable for sophisticated investors who fully appreciate the significance of the risks involved and investors are urged to consult with their own legal and financial advisors before making an investment in our securities.

Risks Relating to Our Business

The telecommunications services market is characterized by rapid technological change, which could render our services obsolete or non-competitive and result in the loss of our market share and a decrease in our revenues.

        The telecommunications industry is subject to rapid and significant changes in technology and is characterized by the continuous introduction of new products and services. The mobile telecommunications industry in Russia is also experiencing significant technological change, as evidenced by the introduction in recent years of new standards for radio telecommunications, such as Wi-Fi, Worldwide Inter-operability for Microwave Access ("Wi-Max"), Enhanced Data Rates for Global Evolution ("EDGE"), Universal Mobile Telecommunications System ("UMTS"), and Long Term Evolution ("LTE"), as well as ongoing improvements in the capacity and quality of communications, shorter development cycles for new products and enhancements and changes in customer requirements and preferences. Such continuing technological advances make it difficult to predict the extent of the future competition we may face and it is possible that existing, proposed or as yet undeveloped technologies will become dominant in the future and render the technologies we use less profitable or even obsolete. New products and services that are more commercially effective than our products and services may also be developed. Furthermore, we may not be successful in responding in a timely and cost-effective way to keep up with these developments. Changing our products or services in response to market demand may require the adoption of new technologies that could render many of the technologies that we are currently implementing less competitive or obsolete. To respond successfully to technological advances and emerging industry standards, we may require substantial capital expenditure and access to related or enabling technologies in order to integrate the new technology with our existing technology.

We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies.

        The wireless telecommunications services markets in which we operate are highly competitive, particularly in Russia and Ukraine. We also face increased competition in our cable TV and fixed line business, while the market for fixed line communications services in Russia is rapidly evolving and becoming increasingly competitive. Competition is generally based on price, product functionality, range of service offerings and customer service.

        Generally, increased levels of competition, including from the potential entry of new mobile operators, government-backed operators, mobile virtual network operators and alternative fixed line operators in the markets where we operate, as well as the strengthening of existing operators, increased use of Internet protocol telephony and other services, provided via the internet, may adversely affect our ability to keep the level of revenue which we receive from our operations on the telecom market. This in turn could result in reduced operating margins and a loss of market share, as well as necessitating different pricing, service or marketing policies, which may have a material adverse effect on our business, financial condition and results of our operations.

Competition in the Russian market

        Our principal wireless competitors in Russia are Public Joint Stock Company "Vimpel-Communications" ("VimpelCom"), Public Joint Stock Company MegaFon ("MegaFon"), as well as the federal cellular operator established in 2014 by the combination of Tele2 Russia and the mobile assets of Public Joint Stock Company Long-Distance and International Telecommunications "Rostelecom" ("Rostelecom"). We also face competition from several regional operators.

        In addition, we face competition in the fixed line telecommunications business, in particular from Rostelecom. Mass media reported that Rostelecom was determined by the Governmental Decree to be

6

---

Table of Contents

the only provider of Internet services for state and commercial medical institutions. It was also reported that Rostelecom may be the only provider of telecommunications services except mobile communications services for federal state institutions. Implementation of these Decrees requirements could have a material adverse effect on our business and results of operations.

        See also "—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices, which may diminish our market share and result in a loss of revenues and margins" below.

Competition in the foreign markets of our operation

        The Association Agreement with the European Union signed by Ukraine, which came into force on September 1, 2017, may adversely affect our business, financial condition and results of operations due to a possible increase in competition. The implementation of the Association Agreement requires the harmonization of Ukrainian legislation and the adoption of certain EU regulations on telecommunications services. In this regard, no assurance can be given as to the exact nature of the intended changes, their potential implementation and possible impact on our business.

        In Ukraine, competition in the markets within which we operate has been affected by the launch of 3G/UMTS services. Through cooperation with Vodafone, MTS Ukraine has started operating in Ukraine under the Vodafone brand. The competitive situation in Ukraine may be further affected by (i) the planned introduction of a mobile number portability service ("MNP"), although the terms of its implementation still remain unknown (interestingly, the regulatory framework for MNP has already been implemented in Russia); (ii) the launch of LTE networks; (iii) the possible emergence of new virtual mobile network operators in the market (for instance, Europe's largest virtual operator, Lyca Mobile, provides communication services in Ukraine on the basis of the TriMob network); and (iv) the regulator's plans to reduce tariffs for international roaming.

        In Belarus, our associate, MTS Belarus, faces increasing competition and aggressive pricing from Best CJSC, a subsidiary of System Capital Management and Turkcell Iletisim Hizmetleri A.S. ("Turkcell"), which operates in Belarus under the "life:)" brand. Additionally, in 2011, the government of Belarus announced its intention to hold a public tender to privatize a 51% stake in MTS Belarus with an opening price of approximately USD 1 billion. The public tender was scheduled to be held on December 23, 2011 but was cancelled due to a lack of bidders. The latest attempt to find an investor for the 51% stake in MTS Belarus took place in February 2014. However, it was unsuccessful for the same reason. A date for the next tender has not yet been specified. The terms of the share disposal have not yet been determined, although it may be conducted either through a public tender or by entering into a direct contract with a prospective purchaser. If we are unable to acquire this ownership interest at a commercially reasonable price, or if it is acquired by one of our competitors, it may impact our competitive position and results of operations in Belarus.

        We also face competition in Armenia. On July 22, 2015, Orange announced its decision to leave the Armenian market and 100% of Orange Armenia's shares were sold to an Armenian internet service provider, Ucom. The transaction was approved by the Public Services Regulatory Commission of the Republic of Armenia on August 20, 2015.

We are subject to anti-corruption laws in the jurisdictions in which we operate, including anti-corruption laws of Russia and the US Foreign Corrupt Practices Act (the "FCPA"), and we may be subject to the UK Bribery Act 2010 (the "UK Bribery Act"). Our failure to comply therewith could result in penalties which could harm our reputation and have a material adverse effect on our business, financial condition and results of operations.

        We are subject to the FCPA, which generally prohibits companies and their intermediaries from making improper payments to foreign officials for the purpose of obtaining or keeping business and/or

7

---

Table of Contents

other benefits, along with various other anti-corruption laws. We may also be subject to the UK Bribery Act. The UK Bribery Act is broader in scope than the FCPA in that it directly addresses commercial bribery in addition to bribery of public officials and it does not recognize certain exceptions, notably facilitation payments that are permitted by the FCPA.

        We operate primarily in Russia and other countries of the former Soviet Union, many of which pose elevated risks of corruption violations. We and certain of our subsidiaries are in frequent contact with persons who may be considered "foreign public officials" under the FCPA and UK Bribery Act, and therefore, are subject to an increased risk of potential FCPA and UK Bribery Act violations. If we are not in compliance with the FCPA, the UK Bribery Act and other laws governing the conduct of business with government entities (including local laws), we may be subject to criminal and civil penalties and other remedial measures, which could have an adverse impact on our business, results of operations, financial condition and liquidity.

        As disclosed in our public filings, in March 2014, we received requests for the provision of information from the United States Securities and Exchange Commission and the United States Department of Justice relating to an investigation of the Group's former subsidiary in Uzbekistan. See also Note 30 to our audited consolidated financial statements. We continue to cooperate with these investigations. We, the DOJ and the SEC are having discussions about a potential resolution to allegations of non-compliance with the Foreign Corrupt Practices Act (FCPA). However, at this stage, the Group cannot be certain that such discussions will result in a settled resolution or whether there will be further developments in the investigations.

The controlling shareholder has a possibility to determine certain decisions of our governing bodies.

        Sistema, which is a public company, owns a controlling stake in MTS. According to the applicable Russian legislation, Sistema has a possibility to exercise its controlling rights, which may become decisive during consideration of a number of issues by our General Meeting of Shareholders, including, but not limited to (i) making decisions on the issues, requiring simple majority of votes our shareholders participating at the General Meeting, for example, in case of making decisions on dividends payment or approval of the our annual reports; (ii) appointment of the majority or dismissal of all members of our Board of Directors members and other matters. Thus, Sistema can take actions that may conflict with the interests of other security holders. Furthermore, our international, credit, investment and other ratings, which determine, inter alia, peculiarities of our operations, terms of raising debt financing and our other activity can be affected by our controlling shareholder's activity and (or) its ratings. See also "—Risks Relating to our Financial Condition—A change in control could have a material adverse effect on our financial condition and results of operations."

        Controlling shareholder as well as other our shareholders has a right to receive dividends at the amount proportionate to the number of our shares belonging to a respective shareholder. For information about dividends see "Item 5—Operating and Financial Review and Prospects—B. Liquidity and Capital Resources—Capital Requirements." The indentures relating to our outstanding notes and other debt do not restrict our ability to pay dividends. As a result of paying dividends, our reliance on external sources of financing may increase, our credit rating may decrease, and our cash flow and ability to repay our debt obligations, or make capital expenditure, investments and acquisitions could be materially adversely affected.

Failure to effectively implement our geographic expansion strategy as well as difficulties with operational management of the acquired businesses could hamper our continued growth and profitability.

        Our continued growth depends, in part, on our ability to identify attractive opportunities in markets that will grow and on our ability to manage the operations of acquired or newly established businesses. Our acquisitions may occur in countries that represent new operating environments for us

8

and, in many instances, may be located a great distance from our corporate headquarters in Russia. We therefore may have less control over their activities. We may also face uncertainties with respect to the operational and financial needs of those businesses and may, in the course of our acquisitions, incur additional debt to finance the acquisitions and/or take on substantial existing debt of the acquired companies. In addition, it is possible that the countries into which we may expand will be emerging markets and, as with countries of our current presence, subject to greater political, economic, social and legal risks than more developed markets.

        For example, see "—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations" and "—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations." Our failure to identify attractive opportunities for expansion into new markets and to manage the operations of acquired or newly established businesses in these markets could hamper our continued growth and profitability, and have a material adverse effect on our financial condition, results of operations and prospects.

Acquisitions and mergers may pose significant risks to our business.

        We have expanded our business through a number of acquisitions. We will continue to evaluate opportunities to acquire, invest in or merge with other existing operators or license holders in the CIS and in growing markets outside the CIS, as well as other complementary businesses. In 2015, our acquisition focus covered regional mobile operators, as well as one of the largest system integrators and complex IT solutions providers in Russia, NVG JSC ("NVision Group"). In 2016, we acquired 100% of shares in "SMARTS Yoshkar-Ola" JSC and participated in MTS Bank's additional share issuance. In 2017, our acquisitions focused on various segments, including communication and software development companies, as well as management investment companies.

        These and other business combinations entail a number of risks that could materially and adversely affect our business, financial condition, results of operations and prospects, including the following:

•

assumption of the acquired target's liabilities and contingencies;



•

failure to realize any of the anticipated benefits or synergies from any acquisitions or investments we complete;



•

problems connected with integrating the acquired businesses, technologies or products into our operations;



•

incurrence of debt to finance acquisitions and higher debt service costs related thereto;



•

difficulties in retaining business relationships with suppliers and customers of the acquired companies;



•

risks associated with businesses and markets in which we lack experience, including political, economic, social, legal and regulatory risks and uncertainties;



•

competition risks;



•

potentially incorrect assessment of the value of any acquired target resulting from the facts we could not have known at the time of evaluation (subsequently discovered facts);



•

more onerous government regulation;



•

potential loss of key assets of the acquired company;



•

potential loss of key employees of the acquired company;

9

Table of Contents

•

potential write-offs of acquired assets; and



•

lawsuits arising out of disputes over ownership of acquired assets and/or the enforcement of indemnities relating to the title to such assets.

        See also "—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" and "—Risks Relating to our Financial Condition—We may be adversely affected by the current economic environment."

        In addition, companies that we acquire may not have internal policies, including accounting policies and internal control procedures that are compatible, compliant or easily integrated with ours.

        If any of our future business combinations is structured as a merger with another company, or we merge with or absorb a company subsequent to its acquisition by us, such a merger would be considered a corporate reorganization under Russian law. This would entitle our creditors to file a claim seeking to accelerate their claims or terminate the respective obligations and seek damages. The creditors would need to prove in court that we will not perform our obligations in due course and the amount of damages suffered. Secured creditors would also be required to prove that the security provided by our shareholders, any third parties or us is not sufficient to secure our obligations. Creditors whose claims are secured by pledges do not have the right to claim additional security.

        As of December 31, 2016, we held a 26.6% stake in MTS Bank. As a participant of the state recapitalization program, at the end of 2015, MTS Bank received federal loan bonds for total value of RUB 7.25 billion from the Deposit Insurance Agency. In 2016, Sistema and MTS participated in the additional share issuance of MTS Bank in proportion to our direct ownership stakes. In February 2016, MTS signed a binding agreement with MTS Bank, pursuant to which we acquired 946,347 ordinary shares in MTS Bank's additional shares issuance for RUB 1.3 billion. In November 2016, we acquired 2,637,310 ordinary shares in MTS Bank's additional shares issuance for RUB 2.77 billion. As of December 31, 2017, we held a 26.6% stake in MTS Bank.

        On January 22, 2015, our subsidiary MGTS closed deals for the sale of a 49.95% stake in Joint Stock Company "Intellect Telecom" and the acquisition of an 89.536% controlling stake in Public Joint Stock Company "Navigation-information systems." In 2015, we acquired 100% of shares in NVision Group, one of the largest system integrators and complex IT solutions providers in Russia. These acquisitions will allow us to improve control over our billing system, reduce our billing and IT related expenses, develop our proprietary technological platform for machine-to-machine ("M2M") solutions and enhance our presence in the areas of telematics solutions for transport, insurance and security systems.

        In September 2016, we entered into a purchase agreement to acquire 100% of shares in "SMARTS Yoshkar-Ola" JSC for RUB 13 million.

        On July 27, 2017, MTS acquired 100% of the shares of Bashkortostan Cellular Communication OJSC in order to gain access to the frequency resource in the range of 2100 MHz in the territory of the Republic of Bashkortostan. On September 29, 2017, MTS acquired 30% in the share capital of Sistema-Capital Management Company LLC, one of the largest management companies in Russia in terms of collective investment volume. In October 2017, MTS acquired a 50.82% stake in Oblachny Retail LLC (operating under LiteBox trademark), a Russian retail software developer. In December 2017, MTS entered the gaming market through the acquisition of Praliss Enterprises, which manages the Gambit Esports team.

        These acquisitions have allowed us to diversify our business. However, additional risks relating to acquired companies' liabilities and non-achievement of initial financial and operational targets may

arise in connection with these acquisitions. See also Note 4 to our audited consolidated financial statements.

        We may also be involved in various litigation to protect our title or other rights related to acquired businesses and incur loss.

        In addition, a merger or any corporate reorganization or business combination that constitutes a "major transaction" under Russian law would trigger the right of our shareholders who abstain from voting on or vote against such reorganization or transaction to sell, and our obligation to buy, their shares in an amount representing up to 10% of our net assets as calculated under Russian Accounting Standards. See "—Legal Risks and Uncertainties—Shareholder rights provisions under Russian law could impose additional obligations and costs on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

If we cannot successfully develop our network or integrate the acquired companies, we will be unable to expand our subscriber base and maintain our profitability.

        Our ability to increase our subscriber base depends upon the success of our network expansion.

        We have expended considerable amounts of resources to enable both organic expansion and expansion through acquisitions, and we plan to continue to do so. Limited information regarding the markets into which we have or are considering expanding, through either acquisitions or new licenses, complicates accurate forecasts of future revenues from those regions, increasing the risk that we may overestimate these revenues. In addition, we may not be able to integrate previous or future acquisitions successfully or operate them profitably. Any difficulties encountered in the transition and integration process and in the operation of acquired companies could have a material adverse effect on our results of operations.

        The build-out of our network is also subject to risks and uncertainties, which could delay the introduction of services in some areas and increase the cost of network construction, including difficulties in obtaining base station sites on commercially attractive terms. Further, telecommunications equipment used in Russia, Ukraine and other CIS countries is subject to governmental certification and periodic renewals of the same. We are also required to obtain permits and governmental certification for the operation of telecommunications equipment and/or permission for the import and export of certain network equipment, which can result in procurement delays and slower network development. The failure of any equipment we use to receive timely certification or re-certification, as applicable, could hinder our expansion plans. See also "—Risks Relating to our Financial Condition—If we are unable to obtain adequate capital, we may have to limit our operations substantially, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

        For example, the import and export of products containing cryptographic hardware is subject to special documentation requirements and approvals. As telecommunications networks comprise various components with cryptographic hardware, we must comply with these requirements in order to import such components. Moreover, where imported equipment does not contain cryptographic hardware, the federal customs service requires manufacturers to provide written confirmation regarding the absence of such hardware. The range of goods requiring the provision of such "certificates of conformance" by suppliers and manufactures prior to their import into Russia has also been expanded to cover most of our key network components, and imported radioelectronic equipment is required to be licensed by the Russian Ministry of Industry and Trade. Similar requirements regarding the import and export of cryptographic hardware exist in Ukraine.

Our inability to develop additional sources of revenue and competitive services could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Until recently, customer growth has been our principal source of revenue growth. Currently, however, increasing competition, market saturation and technological development lead to the increased importance of data services in the markets in which we operate. As a result, data services became the key driver of our revenue growth and we will therefore need to continue to develop new competitive services, including value-added, 3G, LTE, and others, and to consider vertical integration opportunities through the development or acquisition of dealers in order to provide us with sources of revenue in addition to standard voice services. Our inability to develop additional sources of revenue could have a material adverse effect on our business, financial condition, results of operations and prospects.

The failure to launch and develop distribution network in Ukraine.

        VF Ukraine is in the process of launching a distribution network in Ukraine. The retail business of telecommunications operators is sensitive to changes in the economic environment, state regulation and economic policies and can be affected by the national currency exchange rate volatility. An economic downturn or an increased national currency exchange rate volatility may significantly increase price competition and thereby hinder our subscriber growth rate, which could lead to loss of revenues and retail margin. The inability to launch and develop distribution network in Ukraine, could have a material adverse effect on our business, financial condition, results of operations and prospects.

Changes in the governmental regulation of SMP operators in Ukraine could adversely affect our results of operations.

        The interconnect fees charged by us and our competitors for terminating calls connecting to any of our respective networks are subject to regulation by the National Commission for the State Regulation of Communications and Informatization (the "NCCIR"). See "Item 4—Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Interconnect Arrangements and Telephone Numbering Capacity" for additional information.

        A qualification as an SMP has been assessed with reference to the market as defined by the NCCIR According to the Telecommunications Law, an operator qualifies as an SMP in a particular market if its share of gross revenue from the provision of services during the last 12 months exceeded 25% of the total gross revenue of all telecommunications operators for the same services during the same period. Since 2011, the legislation separates fixed and mobile telecommunications networks and the regulation of those networks by the NCCIR. The NCCIR has a right to set different rates for different types of networks. Accordingly, rates for traffic termination on fixed-line networks might be higher than on the network of VF Ukraine. Different rates could lead to a decrease in our revenue share in Ukraine and an increase in costs.

        In the fourth quarter of 2016, a new draft law "On Electronic Communications" was registered in the Verkhovna Rada of Ukraine. The draft law provides for, inter alia, introduction of a "virtual operator" concept, tougher regulation of SMP operators, submission of tariffs in certain electronic communication services markets for approval by the national regulator, mandatory registration of subscribers by providers of electronic communications services (this implies provision of individuals' personal data to communication services providers in case contracts are concluded in other than written form), mutual use of operators' infrastructure, as well as financing of radio frequency monitoring within radio frequency ranges set for public use to be paid for out of the state budget. Some of the initiatives mentioned above have been also included in the draft law of Ukraine "On state administration and regulation in the sphere of electronic communications." In addition, a draft resolution related to the

12

---

Table of Contents

segregation of powers between the NCCIR and the central executive communications authority was registered. The draft law "On Electronic Communications" introduced a power for the central executive communications authority to control and freely access networks and regulations relating to networks operation terms during wartime and/or emergencies. If this law or any other law containing similar provisions is adopted and comes into force, this may influence our revenues and could have an adverse effect on our business, financial condition and results of operations.

        A number of international mobile operators have recently increased fees for interconnecting to their networks for VF Ukraine. A further raise of interconnect fees is likely to result in an increase in costs. In addition, interconnect fees for SMP operators for rendering international roaming may become subject to further governmental regulation.

        To comply with the Presidential Decree No. 146/2017 "On measures aimed at introduction of a visa-free regime with the European Union," the NCCIR approved an action plan for abolishing roaming charges on the territory of the European Union. According to this plan, tariffs reduction is planned in 2019 and 2020 for the countries specified in this plan.

        In September 2017, the European Parliament preliminary approved a possibility of abolition of roaming charges between the European Union and the members of the Eastern Partnership. A decrease in such tariffs may have an adverse effect on our revenue from international roaming charges.

        Additionally, the NCCIR submitted for public discussion a draft procedure for the telecommunications market analysis and identification of SMP operators. This draft describes a procedure for analysing markets to identify SMP companies and implementing by the NCCIR the preliminary regulation of these companies in accordance with the Association Agreement signed by Ukraine and the European Union.

        In accordance with the Association Agreement, it is planned to, inter alia, increase a number of telecommunications markets (to up to 17) where the NCCIR will be responsible for regulating the activities of SMP operators. The adoption of this draft might lead to an increased level of regulation of SMP operators and the reconsideration of current procedure for identifying SMP operators in markets of traffic transfer and traffic termination services.

        The adoption of new procedures, an increased regulation of international tariffs for subscribers and fees for traffic transfer, in addition to an increase in international interconnect fees by the members of the European Union may negatively affect revenues of VF Ukraine.

        See also "—Legal Risks and Uncertainties—Changes in Ukrainian telecommunications legislation have caused uncertainty in relation to the regulation of the Ukrainian telecommunications industry and may adversely affect our business, financial condition and results of operations."

If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices, which may diminish our market share and result in a loss of revenues and margins.

        Our ability to provide commercially viable services depends on our ability to continue to interconnect cost-effectively with zonal, intercity and international fixed-line and mobile operators in Russia, Ukraine and other countries in which we operate. Interconnect fees are established by agreements with network operators and vary depending on the network used, the nature of the call and the call destination. In Ukraine, the connection fees for the SMP operators' networks and interconnect fees for the termination of traffic on such networks are established and regulated by the NCCIR.

        Since 2014, the NCCIR has planned to lower interconnect fees for the termination of traffic on SMP operators' networks. By the resolution dated August 4, 2015 "On the introduction of traffic transmission rates over the network of telecommunications operators with significant competitive

13

Table of Contents

advantage on traffic transmission services market," the NCCIR approved new rates valid from October 1, 2015. As a result, interconnect rates for the termination of both national traffic on fixed-line networks and traffic on mobile networks were lowered, and the rates for the termination of traffic on local networks remained unchanged. The "Rules for setting traffic transmission rates to the networks of telecommunications operators with significant market advantage" were adopted by the NCCIR and forwarded for registration by the Ministry of Justice of Ukraine on June 7, 2016 following their approval by the relevant government bodies. The rules were registered, published and came into force on July 26, 2016. In accordance with these rules, new rates for access to the networks of SMP operators, both at national and international levels, were introduced and approved by the NCCIR on August 30, 2016 and came into force on January 1, 2017.

        The reduction of interconnect fees for the termination of traffic on the networks of SMP operators may adversely affect VF Ukraine's revenues.

        Although Russian legislation requires that operators of public switched telephone networks that are deemed to be "substantial position operators" cannot refuse to provide interconnect services or discriminate against one operator over another, we believe that, in practice, some operators attempt to impede wireless operators by delaying interconnect applications and establishing technical conditions for interconnecting that can be met only by certain operators.

        Any difficulties or delays in interconnecting cost-effectively with other networks could hinder our ability to provide services at competitive prices, or at all, causing us to lose our market share and revenues, which would have a material adverse effect on our business and results of operations. See also "—If we or any of our mobile network operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

        In addition, as part of the restructuring of Svyazinvest, a fourth national mobile operator in Russia was established by the combination of "Tele2 Russia" and the mobile assets of Rostelecom in 2014, which started its operations in 2015 under the "Tele2" brand. As Svyazinvest controlled regional fixed-line operators in all regions of Russia (other than Moscow), a mobile operator established as part of the Svyazinvest group (mobile assets were consolidated into LLC "T2 RTK Holding") may receive preferential terms for interconnecting with these operators, which would allow it greater flexibility in setting tariffs and could put us at a competitive disadvantage. It is currently unclear how the establishment of the fourth federal mobile operator may impact our interconnect agreements and our expenses. See also "—We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies."

We may not realize the benefits we expect to receive from our investments in 3G and 4G wireless services and Internet of Things (IoT) technologies, which could have a material adverse effect on our business and results of operations.

        In May 2007, the Federal Service for Supervision in the Area of Communications and Mass Media awarded MegaFon, VimpelCom and us a license to provide 3G services in the Russian Federation. In July 2012, these three companies and Rostelecom were awarded licenses to provide 4G services.

        Following the integration of Rostelecom's mobile assets and Tele2 Russia in 2014, Tele2 Russia got control over licenses to provide 3G and 4G services. The 3G license allows us to provide mobile radiotelephone services using the International Mobile Telecommunications-2000 ("IMT-2000/UMTS") standard. The 4G license allows us to provide services using the LTE standard. The 4G wireless services are expected to provide faster, higher quality data transfer and streaming capabilities, as compared to 2G and 3G, and may pose additional competition for 3G providers. In December 2017, the State Commission for Radio Frequencies issued a decision allowing the use the frequency bands

previously allocated for LTE mobile communications for NB-IoT technology. Historically, mobile operators that developed 3G and 4G networks experienced various difficulties and challenges, including a limited supply of compatible handsets, limited international roaming capabilities, as well as various 3G and 4G software and network related problems. We may experience similar problems or encounter new difficulties when developing our 3G and 4G networks (including NB-IoT) and may be unable to fully resolve them. For example, we cannot be certain that:

•

we will be able to build-out our 4G and NB-IoT network in a timely manner or within the time frame stipulated by the license terms;



•

our 3G and 4G networks and services (including NB-IoT) will deliver the quality and level of service that our customers demand or expect;



•

we will be able to provide all contemplated 3G and 4G services (including NB-IoT) at reasonable prices and within a reasonable timeframe;



•

manufacturers and content providers will develop and offer new marketable products and services for our 3G and 4G networks (including NB-IoT) on a timely basis;



•

demand for our 4G services (including NB-IoT) will not be lower than expected;



•

our 3G and 4G networks will be commercially viable in all of the locations we are required to operate pursuant to our 3G and 4G licenses;



•

our competitors will not offer similar services at lower prices; and



•

changes in governmental policies, rules, regulations or practices will not affect our network rollout or our business operations.

        See also "—If we cannot successfully develop our network or integrate the acquired companies, we will be unable to expand our subscriber base and maintain our profitability."

        In addition, Russian military authorities also use frequencies in the 3G and 4G spectrum, which may limit the availability of 3G and 4G frequencies for commercial use in certain areas. During the construction of our 3G and 4G networks, there is also a risk that the frequencies assigned to us for commercial use may overlap with those used by the Russian military authorities. For example, conflicts over the availability of frequency reserved for military use in Moscow caused delay in the commercial launch of 3G services by all 3G license-holders in Moscow, despite the fact that some of these frequencies were cleared for commercial use in 2009. If a similar conflict were to occur, it could cause problems or delays in the development and operation of our 3G and 4G networks in Russia.

        Potential competition from other 3G and 4G providers, together with any problems relating to the rollout of our 3G and 4G networks and provision of 3G and 4G services in the future, could materially adversely affect our business, financial condition and results of operations.

        In December 2013, July 2014 and in July 2017, the State Commission for Radio Frequencies introduced several modifications to the conditions of using the frequency band for mobile radio communication networks. These changes resulted in the implementation of the principle of technological neutrality for frequency bands 900 MHz (UMTS and LTE), 1800 MHz (LTE) and 2100 MHz (LTE), and included the imposition of certain additional obligations on network operators. Pursuant to these modifications, in the event that we receive new bandwidth allocation, and as a result of the renewal of the current decisions of the State Commission for Radio Frequencies or in case of using frequencies on the terms of technological neutrality principle, we are obliged to provide network coverage to settlements with lower subscriber numbers, where the commercial rationale for doing so may otherwise be limited. Such changes lead to additional costs for the construction of our 3G and 4G wireless networks and may therefore adversely affect our business, financial condition and results of operations.

If we are unable to successfully develop and/or deploy 4G wireless services in the countries in which we operate, or if any operators in those markets obtain a significant technological and/or commercial advantage over us in 4G wireless services, it may have a material adverse effect on our business and results of operations in the long term.

        The next step in the development of telecommunications in the countries where we operate is the deployment of 4G/LTE networks. The cost of 4G/LTE network development and quality of services (including data speed and quality of coverage) depends on the band and the width of frequency range given to an operator.

        In September 2011, the Russian government announced its intention to auction frequencies for LTE use on a national level in 2012. Additionally, outside of the auction process, the State Commission for Radio Frequencies granted Scartel (operating the "Yota" retail brand) a paired range of LTE frequencies (2x30 MHz) in the 2.5-2.7 GHz band for use in the entire territory of Russia in exchange for the 4G frequencies held by Scartel for Wi-Max technology with a total bandwidth of 70MHz. Four sets of frequencies in the 791-862 MHz band were planned to be sold during the auction in 2012, after which the successful bidders would receive frequencies in the 2.5-2.7 GHz band. The remaining frequencies, 40 MHz of the 2.5-2.7 GHz band, were allocated evenly during the auction among four major market participants (VimpelCom, MegaFon, Rostelecom and us).

        Initially, it was planned that all operators would receive equal access to the Scartel infrastructure, which would allow each operator to reduce its 4G/LTE network development costs. In March 2011, MTS, MegaFon, VimpelCom and Rostelecom signed a non-binding memorandum of understanding with Scartel, according to which MTS, MegaFon, VimpelCom and Rostelecom were to receive access to Scartel's 4G network infrastructure (which was yet to be built) and were to receive options to purchase shares in Scartel in 2014 at a price determined by an independent appraisal. MTS considered the preliminary value assessment of Scartel to be unduly high.

        In July 2012, Alisher Usmanov and Scartel shareholders (Telconet Capital and Rostechnologyi) formed a telecommunications holding company, Garsdale. In exchange for an 82% stake in Garsdale, AF Telecom, which is controlled by Alisher Usmanov, contributed 50% of MegaFon's shares into Garsdale's share capital. Rostechnologyi and Telconet Capital, which held 25.1% and 74.9% stakes in Scartel, respectively, contributed 100% of Scartel shares into Garsdale's share capital, in return for which they received an 18% stake in Garsdale, which was split equally between Rostechnologyi and Telconet Capital. On July 12, 2012, the Federal Service for Supervision of Communications, Information Technology and Mass Media (the "Roskomnadzor") awarded each of MTS, MegaFon, VimpelCom and Rostelecom a license to provide 4G services using LTE and its subsequent modifications in the frequency range of 791-862 MHz.

        On October 1, 2013, MegaFon acquired Maxiten Co Limited, which had acquired 100% of shares in Scartel and Yota Ltd. from Garsdale. The transaction was approved by a general shareholders' meeting of MegaFon and by the Federal Antimonopoly Service (the "FAS"). At present, MegaFon holds a 4G/LTE network through Scartel as well as controlling the continuous spectrum of frequencies 2-40 MHz in the band of LTE FDD 2600 MHz. As a result of this transaction, MegaFon obtained a competitive advantage in terms of LTE network development costs and may also obtain an advantage in LTE network performance. In addition, as a result of this deal, MegaFon consolidated the financial and operational indicators of Scartel/Yota, which increased its formal market share in the mobile communications market.

        Furthermore, the limited number of available frequencies may prevent us from realizing the full benefits we expect to receive from the development of a 4G network, because our network capacity would be constrained and our ability to expand limited. Moreover, if we cannot develop a commercially viable 4G network, and one of our competitors does, that competitor would have an advantage over us, which in turn may have a material adverse effect on our business.

        According to the Decree of the President of Ukraine No. 445/2015 dated July 21, 2015, "On Ensuring Conditions for the Introduction of the Fourth-Generation Mobile Communication System," the Cabinet of Ministers of Ukraine was assigned to develop and approve the 2015-2017 Action Plan for the introduction of the fourth-generation mobile communications system in Ukraine in 2017, in cooperation with the NCCIR and other state authorities. The Action Plan was approved by the Cabinet of Ministers of Ukraine at the end of 2015.

        In 2017, a number of government documents and decisions of the NCCIR regarding the preparation of a tender for 4G licenses in the 1800 MHz band was adopted. The government announced two tenders for 4G/LTE frequencies: for the 2600 MHz band (was held at the end of January 2018) and the 1800 MHz band (was held in March 2018). Significant material resources for the introduction of such new technologies may be required that could have a material adverse effect on our business and results of operations. In addition, there is a number of risks associated with holding tenders for 4G/LTE frequencies in Ukraine, for example, the results of the tender for the 1800 MHz band might be challenged, which could result in additional costs we would have to incur to prevent the degradation of our mobile networks.

Service disruptions on our networks could lead to a loss of subscribers, damage to our reputation, violations of the terms of our licenses and subscriber contracts and penalties.

        We are able to deliver services only to the extent that our information communication infrastructure and data processed therein is protected from unlawful actions, including hacker and targeted attacks, technical malfunctions, power failures and natural disasters. Any system failure, accident or security breach that causes interruptions in our operations could impair our ability to provide services to our customers and materially adversely affect our reputation, business and results of operations.

        In addition, to the extent that any disruption or security breach results in a loss of or damage to customers' personal data or applications, or inappropriate disclosure of confidential information, we may incur liability as a result, including costs to remedy the damage caused by these disruptions or security breaches.

        While we maintain back-up systems for our telecommunications equipment, network management, operations and maintenance systems, these systems may not ensure recovery in the event of a network failure. In particular, in the event of extensive software and/or hardware failures, significant disruptions to our systems could occur, leading to our inability to provide services. The quality of our services in roaming (including roaming between networks) also depends, inter alia, on the network quality of our roaming partners which is out of our control. Disruptions in our provision of services could lead to a loss of subscribers, damage to our reputation, violations of the terms of our licenses and subscriber contracts and penalties.

        Our computer and communications hardware is protected through technical and software safeguards. However, it is still vulnerable to fire, storm, flood, loss of power, telecommunications failures, interconnect failures, physical or software break-ins, viruses and similar events. Although our computer and communications hardware is insured against fire, storm and flood, we do not have business interruption insurance to protect us in the event of a catastrophe, even though such an event could have a material adverse effect on our business.

Failure to fulfill the terms of our licenses could result in their suspension or termination, which could have a material adverse effect on our business and results of operations.

        Each of our mobile licenses requires service to be offered by a specific date and some contain further requirements as to network capacity and territorial coverage to be reached by specified dates.

17

Table of Contents

        In addition, all of our mobile licenses require us to comply with various telecommunications regulations relating to the use of radio frequencies and numbering capacity allocated to us, network construction, interconnect rules and technical requirements relating to compliance with law enforcement authorities' requests, among others. If we fail to comply with the requirements of Russian, Ukrainian or other applicable legislation or meet any terms of our licenses, our licenses and other authorizations necessary for our operations may be suspended or terminated, which could significantly limit our operations. In addition to the impact on our operations, the suspension or loss of certain licenses could also constitute an event of default under certain of our debt obligations and cause certain of our debt to be accelerated. A suspension or termination of our licenses or other necessary governmental authorizations could therefore have a material adverse effect on our business and results of operations.

        For example, in February 2015, MTS Ukraine won the bid for the use of the 1950-1965/2140-2155 MHz frequency bands in a tender allocating 3G licenses. On March 24, 2015, MTS Ukraine paid the full amount and received the UMTS license that is valid for a period of 15 years.

        According to the tender terms, all regional centers of Ukraine have to be covered with 3G communication (within the bands granted to the successful bidder) within 18 months from the date of the license issuance, all settlements with a population of over 10,000 have to be covered with 3G communication within the period of six years.

        Our inability to comply with the license conditions may negatively affect our business. Additional investment may also be required for the conversion of radio frequencies and the deployment of 3G services. Either of the foregoing may have a material adverse effect on our business, financial condition, results of operations and prospects.

Failure to renew our licenses, or receive renewed or new licenses with similar terms to our existing licenses, could have a material adverse effect on our business and results of operations.

        Our telecommunications licenses have their expiration dates in various years. For a list of the telecommunications licenses held by us, see "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Licenses."

        These licenses may be renewed upon application to the relevant governmental authorities. Government officials in Russia and the other countries in which we operate consider the compliance with license requirements and the conditions of using the allocated frequency range when deciding whether to renew a license.

        Additionally, new mandatory conditions, which relate to the need for further development of the communication network in order to provide licensed communication services for potential users of the communication service in sparsely populated residential areas, may be introduced when deciding whether to renew a license. These new conditions will require additional investment. Moreover, we may be subject to penalties or our licenses may be suspended or terminated for non-compliance with any such new license requirements. The suspension or loss of certain licenses could significantly limit our operations and cause certain of our debt to be accelerated.

        The license to construct and maintain telecommunications networks and provide services within them was granted to MTS Ukraine on July 12, 2010 and terminated on December 3, 2013. On October 15, 2013, the NCCIR refused to renew the license and recommended that MTS Ukraine receive a new license to provide operations in the telecommunications sector. Receiving a new license involves additional costs in comparison with the renewal of the current one and MTS Ukraine filed a lawsuit against the NCCIR. On November 19, 2013, the claims of MTS Ukraine were satisfied and, on January 28, 2014, the NCCIR extended MTS Ukraine's license for 5 years. At the same time, however,

on January 27, 2014, the NCCIR filed an appeal against the decision of the District Administrative Court of Kiev.

        Taking into account possible long-term lawsuits regarding the extension of the license for rendering cellular network services in 2G standard, MTS Ukraine has asked the NCCIR to provide a new license with no restrictions in special conditions (technologically neutral), which may be used for different technologies, including GSM, UMTS and LTE. On January 27, 2015, the NCCIR made a decision to grant the license for a 15-year period.

        On January 22, 2015, the High Administrative Court of Ukraine considered the appeal submitted by the NCCIR and overturned the decisions of the Court of Appeals and the District Administrative Court, and issued an order rejecting the claim of MTS Ukraine. In March 2015, the High Administrative Court of Ukraine satisfied the application of the NCCIR to annul its decision to extend our license for rendering cellular network services in 2G standard. Later, the High Administrative Court made a ruling refusing to overturn the execution of the NCCIR's decision to extend the license and ordered a retrial on the grounds of breach of procedural rules in the first instance court. The District Administrative Court of Kiev decided to reject the claim of MTS Ukraine on March 25, 2016. On April 22, 2016, MTS Ukraine filed an appeal claim against this decision, which was rejected by the Court of Appeals on May 30, 2016. On June 29, 2016, MTS Ukraine filed a cassation petition to the High Administrative Court of Ukraine that issued a ruling on the cassation petition consideration. The date of consideration has not been scheduled yet.

        Due to the change of the legal entity name from MTS Ukraine to VF Ukraine, the NCCIR refused to reissue the foregoing license considering judicial decisions in its favor that are currently in force (namely, the decisions dated January 22, 2015, March 25, 2016 and May 30, 2016 described above) and canceled the license. This decision has no material impact on the operational activities of VF Ukraine. Since this cancelation, the main telecommunications license that VF Ukraine use is the license granted by the NCCIR on January 27, 2015.

        Failure to renew our telecommunications licenses, or receive renewed or new licenses with similar terms to existing licenses, could significantly limit our operations, which could have a material adverse effect on our business, financial condition and results of operations.

        Until March 2014, telecommunications operators carried out activities and received licenses in Crimea in compliance with Ukrainian legislation. However, following the referendum in Crimea on March 16, 2014 where a vote in favor of Crimea joining the Russian Federation was declared and the subsequent developments in the region, certain countries recognized Crimean secession whereas others did not, which means that our licensing status in Crimea and ability to receive continuous cash flow has been uncertain. In addition, due to technical issues that have curtailed our ability to provide telecommunications services to our customers, we suspended our operations in Crimea on August 6, 2014. In October 2014, MTS Ukraine sold its base stations, network infrastructure, IT and telecom equipment and certain other assets located in Crimea through an open tender procedure.

If frequencies currently assigned to us are revoked, or if we fail to obtain renewals of our frequency allocations, our network capacity will be constrained and our ability to expand limited, resulting in a loss of market share and revenues.

        There is a limited number of frequencies available for wireless operators in each of the regions in which we operate or hold licenses to operate. We are dependent on access to adequate spectrum allocation in each market in which we operate in order to maintain and expand our subscriber base. If frequencies are not allocated to us in the future in the required quantities, with the geographic span and for time periods that would allow us to provide wireless services on a commercially feasible basis throughout all of our license areas, our business, financial condition, results of operations and prospects may be materially adversely affected.

        According to the decision of the State Commission for Radio Frequencies No. 13-22-01 dated December 11, 2013, the terms of radio frequency bands usage by radio electronic facilities for mobile communication were supplemented with a requirement to provide the settlements of over 1,000 people with communication services within seven years (depending on the used frequency range). If we are not able to fulfill these requirements, our authorizations for the use of radio frequency spectrum might be either terminated or not prolonged in extrajudicial procedure.

        A loss of allocated spectrum, which is not replaced by other adequate allocations, could also have a substantial adverse impact on our network capacity. In addition, frequency allocations are often issued for periods that are shorter than the terms of the licenses, and such allocations may not be renewed in a timely manner, or at all. If our frequencies are revoked, or if we are unable to renew our frequency allocations, our network capacity would be constrained and our ability to expand limited, resulting in a loss of market share and revenues.

An increase in the fees for frequency spectrum usage could have a negative effect on our financial results.

        The terms of our licenses in Russia and the CIS require that we make payments for frequency spectrum usage. Any significant increase in the fees payable for the frequency channels that we use or additional frequency channels that we need in Russia or the CIS could have a negative effect on our financial results. A number of projects implemented by MTS in 2016 and 2017, as well as a number of normative acts previously adopted by the Ministry of Communications, resulted in the expansion of the range of frequencies that have to be paid for.

        On December 31, 2014, a new procedure for payment for frequency spectrum usage came into force. According to the newly adopted amendments, the fees for frequency spectrum usage are calculated based on the total frequency band allocated to each operator in each region with such frequency spectrum usage determined with reference to the decision of the State Commission for Radio Frequencies, frequency allocation decisions or to the license conditions.

        Furthermore, the order of the Ministry of Communications No. 279 dated September 4, 2014 introduced corresponding amendments into the "Methodology of calculation of a single fee and annual fee for the use of the radio spectrum of the Russian Federation" approved by the order of the Ministry of Communications dated June 30, 2011 No. 164. Fees are directly calculated according to this methodology. Under the new order, rates and coefficients are subject to revision at least once every two years. In December 2017 the State Duma approved the Law on federal budget for 2018 and the planned period of 2019 and 2020, which assumes the need of a 25% increase in rent payments for the radio spectrum by the relevant governmental authorities in 2018, 2019 and 2020. To comply with this Law in March 2018, the Ministry of Communications prepared order No. 98, which provides for increase of rent payments for the radio spectrum usage in 2018. Any such increase in payments for the radio spectrum will likely increase our costs and may adversely affect our results of operations.

        With effect from January 1, 2015, the fee for radio spectrum usage in Ukraine was transformed into a rent payment. When adopting a state budget for 2016, the Verkhovna Rada introduced a number of amendments to the Tax Code of Ukraine, including the increase in rent payment for radio spectrum usage by 13.35% commencing January 1, 2016.

        The laws of Ukraine "On State Budget of Ukraine for 2017" and "On amendments to the Tax Code for Budget Stability in 2017" that provide for, inter alia, the reconsideration of both rent payments for radio frequency usage and fees payable for frequency licensing were adopted on December 21, 2016 and December 20, 2016, respectively. The amount of rent payments in 2017 increased insignificantly as compared to the previous years. If these rates are raised further, it may adversely affect our financial and operating results.

If we are unable to maintain our favorable brand image, we may be unable to attract new subscribers and retain existing subscribers, which may lead to a loss of market share and revenues.

        Developing and maintaining awareness of our brands is critical to informing and educating the public about our current and future services and is an important element in attracting new subscribers.

        We believe that the importance of brand recognition is increasing as our markets become more competitive. Successful promotion of our brands will depend largely on the effectiveness of our marketing efforts and on our ability to provide reliable and useful products and services at competitive prices. Brand promotion activities may not yield increased operating revenues and, even if they do, such operating revenues may not offset the operating expenses we incur in building our brands.

        Furthermore, our ability to attract new subscribers and retain existing subscribers depends, in part, on our ability to maintain what we believe to be our favorable brand image. Negative publicity or rumors regarding our company, our shareholders and affiliates or our services could negatively affect our brand image, which could lead to a loss of market share and revenues. Failure to successfully and efficiently promote and maintain our brands may limit our ability to attract new subscribers and retain our existing subscribers and materially adversely affect our business and results of operations.

MTS is a part of the Sistema group and may potentially enter into agreements with other members of the group (i.e. related parties transactions) on terms, which are different from those that would be obtainable on an open market.

        We have purchased interests in various companies from Sistema and entered into agreements with other companies within the Sistema group for the provision of advertising services ("Maxima Advertising" JSC), connectivity facilities and telephone numbering capacity (MGTS), IT services and hardware purchases ("STS" JSC, SITRONICS CAMS JSC, "SST" LLC and NVG JSC), banking services (MTS Bank, formerly Moscow Bank of Reconstruction and Development ("MBRD")), telecommunications services (Stream LLC), medical services ("Medsi Group" JSC), travel services (VAO "INTOURIST"), billing system development and IT integration services (NVG JSC and "STS" JSC), maintenance of the residential and commercial real estate ("SITTEL" CJSC) and other services. According to the applicable Russian legislation and notwithstanding certain control procedures in respect of related parties transactions, related parties transactions with the companies within the Sistema group may potentially be concluded on terms, which are different from those that would be obtainable on an open market. See "Item 7—Major Shareholders and Related Party Transactions—B. Related Party Transactions."

In the event that our past or future interested party transactions are successfully challenged, our business, financial condition, results of operations and prospects could be materially adversely affected.

        We own less than 100% of the equity interests in some of our subsidiaries. In addition, certain of our wholly owned subsidiaries have had other shareholders in the past. We and our subsidiaries in the

past have entered into, and continue to enter into, transactions that may be considered to be "interested party transactions" for the purposes of Russian law, requiring in some cases consent or approval by disinterested directors, disinterested independent directors, disinterested shareholders or owners of voting shares, depending on the nature of the transaction and parties involved. The provisions of Russian law No. 208 "On Joint-Stock Companies" dated December 26, 1995, as amended (the "Joint Stock Companies Law") relating to "interested party transactions" have recently been amended and may be subject to different interpretations taking into account, inter alia, the lack of court practice in respect of the new amendments. As a result, it is possible that our and our subsidiaries' interpretation and application of these provisions could be subject to challenge. Any such challenge, if successful, could result in the invalidation of transactions, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

In the event that our minority shareholders or the minority shareholders of our subsidiaries do not consent to or approve certain transactions or other matters requiring their consent or approval we could be limited in our operational flexibility, and our business, financial condition, results of operations and prospects could be materially adversely affected.

        Russian law requires a three-quarters majority vote of the holders of voting stock present at a shareholders' meeting to consent to or approve certain transactions and other matters, including, for example, charter amendments, major transactions involving assets in excess of 50% of the total assets of the company, purchase of offered shares by the company and certain share issuances. In addition, a 95% or a unanimous vote is required to approve certain matters, for example, certain charter amendments regarding shareholders' rights. A majority of disinterested shareholders participating in the voting is required to consent to or approve an "interested party transaction" in certain cases. In the event that our minority shareholders or minority shareholders of our subsidiaries do not consent to or approve such transactions or other matters requiring their consent or approval, we could be limited in our operational flexibility, and our business, financial condition, results of operations and prospects could be materially adversely affected.

Our competitive position and future prospects depend on our senior managers and other key personnel and our inability to attract, retain and motivate qualified key personnel could have a material adverse effect on our business, financial condition and results of operations.

        Our ability to maintain our competitive position and to implement our business strategy is dependent to a large degree on the services of our senior management team and other key personnel.

        Moreover, competition in Russia and in the other countries where we operate for personnel with relevant expertise is intense due to the relatively small number of qualified individuals. As a result, we attempt to structure our compensation packages in a manner consistent with the evolving standards of the labor markets in these countries. We are not insured against the detrimental effects to our business resulting from the loss or dismissal of our key personnel. In addition, it is not common practice in Russia and the other countries where we operate to purchase key-man insurance policies, and we do not carry such policies for our senior management and other key personnel. The loss or decline in services of members of our senior management team or an inability to attract, retain and motivate qualified key personnel could have a material adverse effect on our business, financial condition and results of operations.

The entry of mobile virtual network operators into the Russian mobile communications market could increase competition and subscriber churn, resulting in a possible loss of our market share and decreased revenue.

        On December 29, 2008, the Ministry of Communications and Mass Media adopted an order establishing the requirements for mobile virtual network operators ("MVNOs"). MVNOs are companies that provide mobile communications services but do not own the radio frequencies and, in some cases,

22

Table of Contents

the network infrastructure required to do so. According to the order, MVNOs in Russia must be licensed, and their use of frequencies and infrastructure and rendering of services is to be done pursuant to agreements entered into between MVNOs and existing frequency holders. However, existing frequency holders are under no obligation to enter into such agreements with the MVNOs.

        By introducing this regime, the Ministry aims to increase competition in the Russian mobile services market, which is currently dominated by MTS, VimpelCom and MegaFon. While existing frequency holders, including us, may receive revenues from MVNOs for the use of our frequencies and network infrastructure, we expect these revenues to be lower than the revenues we would receive if providing services directly to subscribers. In addition, in the event we lose subscribers to MVNOs that lease their frequencies and infrastructure from other operators, we will be deprived of the revenue streams from both the subscribers and the MVNOs. The MVNOs may also establish aggressive tariffs, which could result in increased subscriber churn and/or driving down the tariffs of all mobile operators.

        For example, Skartel (under the "Yota" brand), MGTS, Rostelecom, Tinkoff Bank operate as MVNOs in the Russian mobile communications market.

        It is currently unclear how the emergence of new MVNOs in the market or any of the foregoing trends might affect market competition and subscriber churn, but this could have a material adverse effect on our business, financial condition, results of operations and prospects.

A finding by the FAS that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations.

        Our businesses have grown substantially through the acquisition and formation of companies, many of which required the prior approval of, or subsequent notification to, the FAS or its predecessor agencies.

        In part, relevant legislation in certain cases restricts the acquisition or formation of companies by groups of companies or individuals acting in concert without such prior the FAS approval. While we believe that we have complied with the applicable legislation for our acquisitions and formation of new companies, this legislation is sometimes vague and subject to varying interpretations. If the FAS were to conclude that our acquisition or formation of a new company was done in contravention of applicable legislation, or find our actions insufficient to rectify past violations of antimonopoly laws, or issue new warnings and requests in the future, it could impose administrative sanctions and require the divestiture of such company or other assets, which could have a material adverse effect on our business, financial condition and results of operations.

        In recent years, the FAS has been investigating mobile operators, including MTS, for suspected violations of antimonopoly laws. For example, see "Item 8—Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Antimonopoly Proceedings" and "—Changes to the rules and regulations involving roaming charges in Russia may adversely affect our financial condition and results of operations."

        If the FAS finds that we have violated or otherwise acted in contravention of antimonopoly legislation, this could have a material adverse effect on our business, financial condition, results of operations and prospects.

A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations.

        Under Ukrainian legislation, a company that is found to have acted in contravention of antimonopoly legislation may be subject to fines and claims from the Antimonopoly Committee of Ukraine (the "AMC"). The AMC may investigate us from time to time and, should such investigations identify any violations, impose penalties (including fines).

        Based on the complaint filed by Astelit LLC concerning illegal establishment of regional tariffs, in April 2016, the AMC initiated proceedings relating to a violation of legislation on the protection of economic competition. The case is awaiting consideration.

        In July 2016, the AMC sent requests to the big three operators asking to provide it with information on the establishment of settlement rates for international roaming and interconnect fees with foreign telecommunications operators.

        In August 2016, the AMC began an investigation in relation to antimonopoly restrictions that affect content services market. The case is currently under consideration.

        Based on the complaint filed by Lifecell LLC, in April 2017, the AMC initiated proceedings relating to a violation of legislation on the protection of economic competition. The case is currently under consideration.

        If we are found by the AMC to have violated antimonopoly legislation in the above or any other matters, we may be subject to fines, which may have a material adverse effect on our business, financial condition and results of operations. In addition, we may be required to adjust our current marketing practices. See also "—Changes in the governmental regulation of SMP operators in Ukraine could adversely affect our results of operations" and "Item 4—Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Competition" for additional information.

If we are found to have a dominant position in the markets where we operate and are determined to have abused this position, the FAS may be entitled to regulate our subscriber tariffs and impose certain restrictions on our operations.

        Under Russian legislation, a company controlling between 35-50% or over 50% of a market may be found by the FAS to hold a dominant position in such market. In case of collective dominance of legal entities, a company could be also categorized by the FAS as dominant even if its share of the corresponding market is less than 35%. Current Russian legislation does not clearly define "market" in terms of the types of services or the geographic area. In 2016, as a result of certain amendments to the Federal Law No. 135 "On the Protection of Competition," the register of business entities having more than 35% of a certain commodity market or otherwise occupying a dominant position in the markets in which they operate, which previously listed MTS as occupying a dominant position in certain markets, was repealed. At the same time, the FAS continues to conduct market analysis in order to identify entities holding a dominant position in the markets in which they operate.

        Companies recognized as natural monopolies are also considered to have a dominant position in their respective markets. One of our subsidiaries, MGTS, was categorized as a natural monopoly in the Moscow telecommunications market. As a result, MGTS' tariffs are now subject to regulation by the FAS. In addition, as a natural monopoly, MGTS is obliged to comply with the rules of non-discriminatory third party access to its infrastructure. See also "—MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services."

        In the event that we are found in the future to have a dominant position in the markets where we operate and are either determined to have abused the dominant position or found to have committed concerted actions in the market and/or concluded anti-competitive agreements, the FAS will have a right to impose certain restrictions on our operations in such markets. See "Item 4—Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation—Competition, Interconnect and Pricing" for additional information.

        If we are found to have violated antimonopoly legislation, an order requiring us to transfer any illegally obtained revenue to the federal budget may be issued in relation to such violations. The level of fine ranges from 5% to 15% of revenue in the market where the violation is conducted for cartel agreements and from 1% to 15% of revenue for other violations (with 8% being the base level of the fine for all types of violations).

        If we or any of our subsidiaries were found by the competition authority to be business entities occupying a dominant market position, the competition authority would have a power to impose certain restrictions on our or our subsidiaries' businesses. In particular, the authorities may impose on us tariffs at levels that could be competitively disadvantageous. If we or any of our subsidiaries were found by the FAS to be business entities occupying a dominant market position with a market share exceeding 70% and determined to abuse such dominant position, the Russian government would have a right to determine the rules of non-discriminatory access to goods or services offered by us. Additionally, geographic restrictions on our expansion could reduce our subscriber base and prevent us from fully implementing our business strategy, which may materially adversely affect our business, financial condition, results of operations and prospects.

If we or any of our mobile network operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations.

        In addition to the regulation of dominant operators by the FAS, the Federal Law on Communications provides for the special regulation of telecommunications operators occupying a "substantial position" (i.e., operators which, together with their affiliates, have 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic in a geographically defined zone within the Russian Federation). These regulations provide for governmental regulation of the key terms of such operators' interconnect agreements, including the interconnect tariffs. In addition, such operators are required to develop standard key terms of interconnect agreements and publish them as a public offer made to all operators who intend to interconnect to the networks of those operators. Refusal of such operators to conduct an interconnect agreement is prohibited, except in cases where such agreement would contradict the terms of their license or other regulatory acts in respect of the unified communications network in the Russian Federation.

        For additional information, see "Item 4—Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation."

        At present, the foregoing regulations apply only to fixed-line operators in Russia, including our fixed-line business. Draft legislation was introduced in 2008 that would extend the law to apply to mobile operators. Although the proposed law was not adopted, the risk that similar legislation will be proposed and adopted in the future remains. If any legislation that extends the foregoing regulations to mobile operators is adopted, and we and any of our mobile network operator subsidiaries operating in Russia are identified as operators occupying a "substantial position," regulators may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our revenues, financial condition and results of operations.

        In addition, MGTS is categorized as fixed-line operator occupying a substantial position in the Moscow telecommunications market and its interconnect tariffs are therefore subject to state regulation. In February 2013, Comstar-UTS was removed from the list of "substantial operators" in Moscow and MTS was not included therein. There is however a possibility that we could be categorized as fixed-line operator occupying a "substantial position" in Moscow due to our affiliation with MGTS and because of our integration with Comstar-UTS. As a result of the state regulation of the relevant interconnect rates, we, as "substantial operators," may be unable to increase these in line with

economic developments or any increases of our relevant costs, resulting in a material adverse effect on our financial condition and results of operations. See also "—MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services."

MGTS is subject to extensive regulation of tariffs, and these tariffs may not fully compensate us for the cost of providing required services.

        In addition to holding a "substantial position" in the Moscow telecommunications market, MGTS is included in the register of natural monopolies in the telecommunications market. Consequently, tariffs for basic services rendered to public switched telephone networks subscribers (fees for providing access to a local telecommunications network, monthly fees for granting subscriber line in a constant use and monthly fees for providing a local telephone connection) are subject to regulation.

        Although MGTS is permitted to petition the FAS for increases in tariffs based on such criteria as inflation, increased costs and the need for network investments, it is possible that future requested increases may not be granted or that the FAS may not adequately take such factors into account in setting tariffs. If the permissible tariffs applicable to MGTS do not adequately compensate MGTS for the costs of providing services, our business and results of operations could be materially adversely affected. See also "—If we or any of our mobile network operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

Changes to the rules and regulations involving roaming charges in Russia may adversely affect our financial condition and results of operations.

        In June and July 2017, several draft laws were submitted for consideration to the State Duma, which were intended to change the regulation of roaming services in Russia by eliminating (or reducing) intra-network roaming tariffs and national roaming tariffs for incoming and outgoing calls as well as the regulation of international roaming charges between Russia and Belarus. In addition, in July 2017, the FAS requested mobile operators to cancel roaming fees across Russia. Any revision of roaming charges may lead to a reduction in our revenues.

        Moreover, a resolution was adopted at a meeting of the Supreme State Council of the Union State on June 30, 2017 to examine a matter regarding the cancelation of international roaming charges between Russia and Belarus. The implementation of this initiative may adversely affect our revenues from roaming charges in Belarus and increase our expenditure incurred in connection with the provision of these services.

        In July 2017, the FAS sent a warning to mobile operators, in which it demanded to cancel intra-network roaming. In March 2018, the FAS opened an antimonopoly case against VimpelCom, MTS and MegaFon (in connection with the non-fulfilment of the warning). The revision of tariffs may lead to a reduction of income of MTS and other mobile carriers in Russia.

        In August 2017, the FAS opened an antimonopoly case against VimpelCom, MTS, MegaFon and T2 Mobile LLC on the grounds of establishing and maintenance of monopolistically high prices for communication services in national roaming and inter-operator roaming agreements. On February 22, 2018 the FAS rendered a decision and found MTS responsible for establishing monopolistically high prices for subscribers for communication services in national roaming. VimpelCom, MegaFon and T2 Mobile were also found guilty for establishing monopolistically high prices for subscribers for communication services in national roaming. Àn administrative case is expected to be initiated, which will result in an administrative fine. The case related to inter-operator roaming agreements against MTS was canceled. See also "—A finding by the FAS that we have acted in contravention of

antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations."

        Any material fines imposed on us or changes to the roaming charges may adversely affect our financial condition and result of operations.

Compliance with the new regulations on IMEI numbers may present us with technical difficulties and may lead to the expenditure of significant resources.

        A draft law that enables each mobile communications subscriber to register a user terminal under certain conditions on an International Mobile Equipment Identity ("IMEI") numbers database of the Ukrainian State Center of Radio Frequencies, primarily to prevent their unlawful use, was previously proposed in Ukraine. Aimed at discouraging theft, the draft law required operators to suspend or block the traffic transmission of the terminal upon the application of a subscriber. In July 2015, the draft law was withdrawn from consideration. A similar draft law was rejected by the Russian State Duma.

        Additionally, the Cabinet of Ministers of Ukraine adopted the decision "On introduction of amendments to the Regulation of the Cabinet of Ministers of Ukraine "On introduction of rules relating to rendering and using telecommunications services," which, inter alia, cancels a requirement to block IMEI numbers of terminals not included in the database of the Ukrainian State Center of Radio Frequencies ("USCRF").

        If similar initiatives are proposed in the future, we may be required to develop a system to monitor IMEI numbers and may need to establish and maintain a database of IMEI numbers, which would necessitate the expenditure of significant technical and financial resources.

The accession of Russia to the World Trade Organization (the "WTO") may lead to legislative and business changes.

        On August 22, 2012, the Russian Federation became a member of the WTO. This may lead to potentially significant changes in Russian legislation including, among others, regulation of foreign investments in Russian companies, competition laws, telecommunications laws, changes in the taxation system and customs regulations in Russia. In addition, the implementation of the WTO rules may lead to increased competition in the markets where we operate. During the period of 2012 to 2016, Russia adopted certain changes to its legislation related to the accession to the WTO, for example, regarding intellectual property laws; however, it is still unclear if, and when, all necessary legislative changes related to the WTO accession will take place. If further new legislation is implemented in Russia as a result of its accession to the WTO, this could have a material adverse effect on our financial condition and results of operations.

We may be required to make significant investments beyond those that are currently planned to preserve our competitive advantage in response to the rapid evolution of fixed network technology.

        One of our subsidiaries, MGTS, has devised a number of projects aimed at developing communications networks and expanding availability of telecommunications services for customers. The likely shortage of free cash flow during the current economic downturn could halt such investment programs for the development of new products and services, and possibly lead to a decrease in the number of projects and cutbacks in development programs in the New Moscow and Moscow regions. The company has recently completed its project on construction of broadband optical networks employing the Gigabit-capable Passive Optical Network ("GPON") technology with a direct connection of subscribers to an optical network. The applied part of the GPON project's progress is the creation of a digital platform of IMS core, which enables MGTS to render a larger range of services, including services for the B2G segment. See "Item 4—Information on Our Company—A. History and Development—Capital Expenditure" for further information.

        MGTS attracts contractors for the construction and upgrade of its network. Due to the currently unfavorable market conditions, some of MGTS' contractors may face a lack of own current assets and/or external finance sources which may lead to the contractor's inability to fulfill contract obligations or, in some cases, lead to bankruptcy. This may negatively affect the terms of MGTS projects' implementation and lead to higher costs. If MGTS is not able to expand and upgrade its network infrastructure in a timely manner and offer new services, or if it is required to make significant investments beyond those that are currently planned, our business, financial condition, results of operations and prospects could be materially adversely affected.

Our intellectual property rights are costly and difficult to protect.

        We regard our copyrights, trademarks, trade secrets and similar intellectual property, including our rights to certain domain names, as essential to our continued success. We rely upon trademark, copyright and trade secret protection laws, as well as confidentiality and/or license agreements with our employees, customers, partners and others, to protect our proprietary rights. Nonetheless, intellectual property rights are particularly difficult to protect in the markets where we operate. In these markets, the regulatory agencies responsible for the protection of intellectual property rights are inadequately funded, legislation is underdeveloped, piracy and infringement are commonplace, and enforcement of court decisions is problematic.

        A special court for intellectual property rights was established in July 2013 as a new body in the system of the Arbitrazh Court for dealing with cases relating to the protection of intellectual property rights.

        Litigation may be necessary to enforce our intellectual property rights, to determine the validity and scope of any proprietary rights of others, or to defend against claims of infringement. Any such litigation may result in substantial costs and diversion of resources and, if decided unfavorably to us, could have a material adverse effect on our business. We also may incur substantial acquisition or settlement costs to the extent that it would strengthen or expand our intellectual property rights or limit our exposure to intellectual property claims of third parties. See also "Item 8—Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Other litigation."

        The rules regarding intellectual property rights regulation changed following the adoption of the Federal Law No. 35 dated March 12, 2014, which introduced significant amendments to the fourth part of the Civil Code of the Russian Federation. However, the lack of extensive law enforcement practice of the changed provisions of the Civil Code may cause difficulties in protection of our rights and legitimate interests.

Changes to our current sales and customer care procedures, the creation of new information technology services and the migration of fixed B2B and B2C subscribers to a single information technology solution may destabilize our information technology solutions, which could have a material adverse effect on our business and results of operations.

        Changes to our current sales and customer care procedures, the creation of new information technology services and the migration of fixed B2B and B2C subscribers to a single information technology solution may increase our operational risks and expenses and inconvenience subscribers. The failure or breakdown of key components of our infrastructure in the future, including our billing system and its susceptibility to fraud, could have a material adverse effect on our business and results of operations.

If leaks of confidential information (including any information relating to our subscribers) occur, it may negatively impact our reputation and our brand image and lead to a loss of market share, which could materially adversely affect our business, financial condition, results of operations and prospects.

        Despite our continuous efforts to protect confidential information, breaches of security and leaks of confidential information, including information relating to our subscribers, may negatively impact our reputation and our brand image and result in a loss of market share or otherwise have a material adverse effect on our business, financial condition and results of operations. For example, in January 2003, part of our database of subscribers, containing private subscriber information, was illegally copied and stolen. In addition, in May 2003, certain subscriber databases of several operators in the North-West Region, including those of MTS, MegaFon, Delta Telecom and two other operators, were stolen. In each case, the stolen databases were thereafter available for sale in Russia. Despite the measures taken, we cannot completely exclude the possibility of such incidents occurring in the future. See also "—Legal Risks and Uncertainties—Russian and foreign legislation on personal data and information security in information systems and communication networks may turn out to be hard to implement and require significant resources. Inability to comply with the requirements may lead to sanctions."

Alleged medical risks of cellular technology may subject us to negative publicity or risk of litigation, decrease our access to base station sites, diminish subscriber usage and hinder access to additional financing.

        Electromagnetic emissions from transmitter masts and mobile handsets may harm the health of individuals exposed for long periods of time to such emissions. The actual or perceived health risks of transmitter masts and mobile handsets could materially adversely affect us or our subsidiaries by reducing subscriber growth, reducing usage per subscriber, increasing the number of product liability lawsuits, increasing the difficulty of obtaining or maintaining sites for base stations and/or reducing the financing available to the wireless communications industry. Each of these potential risks may adversely affect our business, financial condition, results of operations and prospects.

Risks Relating to our Financial Condition

We may be adversely affected by the current economic environment.

        As a result of the credit market crisis (including uncertainties with respect to financial institutions and the global capital markets), decreased prices for major export commodities (including oil and metals) and other macro-economic challenges currently affecting many of the markets in which we operate, our subscribers' disposable incomes and our vendors' cash flows may be adversely impacted.

        Consequently, subscribers may modify or decrease their usage of our services or fail to pay the outstanding balances on their accounts, and vendors may significantly increase their prices, eliminate vendor financing or reduce their output.

        We may also experience increases in accounts receivable and bad debt among corporate subscribers, some of whom may face liquidity problems and potential bankruptcy, as well as the potential bankruptcy of our corporate partners. The deterioration of economies in the countries of our operation may lead, inter alia, to insolvency of financial institutions, which in turn may impact our business and financial condition.

        The strained political situation in Ukraine coupled with an economic downturn resulted in financial difficulties in the banking system, including, notably, increased liquidity risks. As we hold the bulk of excess hryvnia and foreign currency cash in Ukrainian banks, a banking crisis or the bankruptcy or insolvency of the banks through which we receive or with which we hold our funds could result in the loss of our deposits or affect our ability to complete banking transactions in Ukraine and other countries, which could have a material adverse effect on our business, financial condition and results of

operations. For example, we realized losses in the fourth quarter of 2014 due to an impairment of cash balances stemming from the insolvency of DeltaBank in Ukraine. In 2015, the Group wrote off certain cash balances deposited in distressed Ukrainian banks. These banks are currently being liquidated.

        See also "—Inflation could increase our costs and adversely affect our results of operations."

        A decline in subscriber usage, an increase in bad debts, material changes in equipment pricing or financing terms or the potential bankruptcy of our corporate subscribers or partners may have a material adverse effect on our business, financial condition, results of operations and prospects.

        In addition, a further deterioration in macroeconomic conditions could require us to reassess the value of goodwill on certain of our assets, recorded as a difference between the fair value of the assets of business acquired and its purchase price. This goodwill is subject to impairment tests on an ongoing basis. The weakening macroeconomic conditions in the countries in which we operate and/or a significant difference between the performance of an acquired company and the business case assumed at the time of acquisition could require us to write down the value of the goodwill or portion of such value. Future write-downs relating to the value of the goodwill or portion of such value could have a material adverse effect on our financial condition and results of operations.

Continued turmoil in the credit markets could cause our business, financial condition, results of operations and the value of our shares and ADSs to suffer.

        Sanctions introduced by the United States and the European Union with respect to the Russian Federation coupled with an economic downturn and decline in global oil prices caused a significant capital outflow, ruble depreciation, a rise of credit rates in the domestic market and a lack of available financing.

        Currently, the situation relating to funding has become more stable as the key rate has been decreasing since 2016. In spite of this, although funding by the Central Bank of Russia is available for a large number of banks, it is characterized by high volatility during periods of economic instability. For example, certain Russian banks have in the past experienced difficulties that have caused them to become insolvent and have their licenses revoked, such as Bank Yugra, or to recognize large loan impairment provision losses that required steps to replenish their capital, as in the case of the Promsvyazbank, Bin Bank and Otkritie Bank.

        A continuation or repetition of this downturn in the global financial markets as well as a toughening or extension of international sanctions against Russia and the resulting volatility of the trading price of our shares and ADSs may negatively impact our ability to obtain financing on commercially reasonable terms, either domestically or overseas, and could have a material adverse effect on our business, financial condition, results of operations and prospects.

Our inability to generate sufficient free cash flow to satisfy our debt service obligations or to refinance debt on commercially reasonable terms, could materially adversely affect our business, financial condition, results of operations and prospects.

        We have an amount of outstanding indebtedness, primarily consisting of the obligations we entered into in connection with our notes and bank loans. As of December 31, 2017, our consolidated total debt, including capital lease obligations, was RUB 303,570 million. Our finance cost for the year ended December 31, 2017 was RUB 26,064 million, net of the amounts of interest capitalized.

        Our ability to service, repay and refinance our indebtedness and to fund planned capital expenditure will depend on our ability to generate cash in the future. This, to a certain extent, is subject to general economic, financial, competitive, legislative, regulatory and other factors that are beyond our control. If we are unable to generate sufficient cash flow or otherwise obtain funds necessary to make required payments, we may default under the terms of our financial indebtedness,

and the holders of our indebtedness would be able to accelerate the maturity of such indebtedness, potentially causing cross-defaults under and acceleration of our other indebtedness. The existing debt servicing is becoming more difficult due to our dependence on floating interest rates in the financial markets.

        We may not be able to generate sufficient cash flow or access domestic or international capital markets, or incur additional loans to enable us to service or repay our indebtedness or to fund our other liquidity needs. We may be required to refinance all or a portion of our indebtedness on or before maturity for a number of reasons. For example, the terms of some of our loan agreements may require us to prepay the loan in certain circumstances, such as a deterioration in our credit rating, a delisting of our shares or a drop in our retained earnings below a certain level. This, in turn, may force us to sell assets, reduce or delay capital expenditure or seek additional capital. Refinancing or additional financing may not be available on commercially reasonable terms or at all, and we may not be able to sell our assets or, if sold, the proceeds therefrom may not be sufficient to meet our debt service obligations. Our inability to generate sufficient cash flow to satisfy our debt service obligations, or to refinance debt on commercially reasonable terms, would materially adversely affect our business, financial condition, results of operations and prospects. See "Item 5—Operating and Financial Review and Prospects—B. Liquidity and Capital Resources."

Ruble volatility and regulatory changes in foreign currency regulation could increase our costs, decrease our available funds or make it more difficult for us to comply with financial covenants and to repay our debts and would affect the value of dividends received by holders of ADSs.

        The ruble has weakened significantly against the U.S. dollar during the period of 2014 to 2016, which can be explained by external geopolitical factors, limited financial markets, decrease in oil prices, international ratings agencies' downgrades of Russia's sovereign rating, reduction in internal consumption and other factors.

        For example, on December 31, 2014, the official exchange rate published by the CBR was 56.26 rubles per U.S. dollar. The ruble continued to depreciate against the U.S. dollar reaching 72.88 rubles per one U.S. dollar on December 31, 2015, whereas on December 31, 2016, it amounted to 60.66 rubles per one U.S. dollar. On December 31, 2017, ruble amounted to 57.60 per one U.S. dollar.

        See also "—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble, as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our financial results."

        The stability of the ruble will depend on many political and economic factors. These include the ability of the government to finance the deficit of the state budget without recourse to monetary emissions and to control the level of interest rates and inflation. Furthermore, changes in foreign currency regulation may affect our ability to fund payments denominated in foreign currency and result in us entering into supplementary agreements with our foreign counterparts.

        A significant portion of our capital expenditure and liabilities and borrowings are either denominated in or tightly linked to the U.S. dollar. Conversely, a majority of our revenues are denominated in rubles. As a result, devaluation of the ruble against the U.S. dollar can adversely affect us by increasing our costs in rubles, both in absolute terms and relative to our revenues, and make it more difficult to comply with the financial ratios contained in our various loan agreements or fund cash payments on our indebtedness on time. It also reduces the U.S. dollar value of tax savings arising from tax incentives for capital investment and the depreciation of our property, plant and equipment, since their basis for tax purposes is denominated in rubles at the time of the investment. Increased tax liability would also increase total expenses, which would have an adverse impact on our results.

        We also anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of the ADSs. Accordingly, the value of dividends received by holders of ADSs will be subject to fluctuations in the exchange rate between the ruble and the U.S. dollar. Any further depreciation of the ruble against the U.S. dollar could therefore materially adversely affect our financial condition, results of operations and prospects and the value of our ADSs. See also "Item 11—Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble, as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our financial results.

        A significant portion of our expenditure and liabilities, including capital expenditure and borrowings (including our U.S. dollar denominated notes), are either denominated in, or closely linked to, the U.S. dollar and/or euro, while substantially all of our revenues are denominated in local currencies of the countries where we operate. If the local currencies of the countries where we operate decline against the U.S. dollar and/or euro and our costs increase so that we cannot keep pace, we could have difficulty repaying or refinancing our U.S. dollar and/or euro-denominated indebtedness, including our U.S. dollar denominated notes. At the same time, the devaluation of local currencies against the Russian ruble can adversely affect our revenues reported in Russian rubles and increase our costs in terms of local currencies. In addition, local regulatory restrictions on the purchase of hard currency in the majority of countries where we operate (for example, Ukraine) may delay our ability to purchase equipment and services necessary for network expansion which, in turn, may cause difficulty in expanding our subscriber base in those countries. Further, a portion of our cash balances is held in jurisdictions outside Russia, and as a result of currency exchange controls in those jurisdictions, these cash balances may not always be readily available for our use.

        Ukraine's economic crisis combined with political unrest and events in the Eastern part of Ukraine have led to the weakening of the hryvnia, with the exchange rate rising from 15.77 hryvnias per one U.S. dollar on December 31, 2014 to 24.00 and 27.19 hryvnias per one U.S. dollar on December 31, 2015 and on December 31, 2016, respectively, as a result of substantial capital outflow in response to the continuing political instability in Ukraine. As of December 31, 2017, the exchange rate amounted to 28.07 hryvnias per one U.S. dollar.

        See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

        The Belarusian ruble depreciated against the U.S. dollar, whereby the exchange rate increased from 11,850 Belarusian rubles per one U.S. dollar on December 31, 2014, to 18,569 Belarusian rubles per one U.S. dollar on December 31, 2015. On July 1, 2016, Belarus redenominated its currency on a scale of 10,000:1. As of December 31, 2016, the official exchange rate published by the National Bank of the Republic of Belarus amounted to 1.96 Belarusian rubles per one U.S. dollar. As of December 31, 2017, the official exchange rate published by the National Bank of the Republic of Belarus amounted to 1.97 Belarusian rubles per one U.S. dollar. The possible devaluation of the Belarusian ruble in the future may adversely affect our revenues from this market.

If we are unable to obtain adequate capital, we may have to limit our operations substantially, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        We have to make significant capital expenditure, particularly in connection with the development, construction and maintenance of, and the purchasing of necessary software for, our mobile and fixed-line networks. We had capital expenditure in the amounts of RUB 96,111 million (excluding costs of RUB 3.382 billion related to the acquisition of a 4G license in Russia and RUB 7.044 billion related to the acquisition of a 3G license in Ukraine in 2015) in 2015, RUB 83,551 million (excluding costs of RUB 2.598 billion for the acquisition of a 4G license in Russia) in 2016 and RUB 76,431 million in 2017. Further, the acquisition of 3G and 4G licenses and frequency allocations and the build-out of our 3G, 4G and broadband Internet networks will require additional capital expenditure. See "Item 4—Information on Our Company—A. History and Development—Capital Expenditure."

        However, future financings and cash flow from our operations may not be sufficient to meet our planned needs in the event of various unanticipated potential developments, including the following:

•

a lack of external financing sources;



•

changes in the terms of existing financing arrangements;



•

construction of the wireless networks at a faster rate or higher capital cost than anticipated;



•

pursuit of new business opportunities or investing in existing businesses that require significant investment;



•

acquisitions or development of any additional wireless licenses;



•

slower than anticipated subscriber growth;



•

slower than anticipated revenue growth;



•

regulatory developments;



•

changes in existing interconnect arrangements; or



•

a deterioration in the economies of the countries where we operate.

        During the period of 2014 to 2018, the United States and the European Union announced sanctions applying to a number of Russian and Ukrainian individuals and associated institutions which were considered to have contributed to the situation in Ukraine and Crimea. The sanctions may be extended and our ability to gain external funding may be affected. See also "—Political and Social Risks—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations" and "—A deterioration in relations between Russia and other former Soviet republics as well as other politically related disagreements and allegations between Russia and other countries and sanctions imposed as a result thereof could materially adversely affect our business, financial condition, results of operations, prospects and the value of our shares and ADSs."

        Our indebtedness and the limits imposed by covenants in our debt obligations could limit our ability to obtain additional financing and thereby constrain our ability to invest in our business and place us at a possible competitive disadvantage. In addition, we are currently unable to raise equity financing through newly issued depositary receipts, such as ADSs, due to Russian securities regulations providing that no more than 25% of a Russian company's shares may be circulated abroad through sponsored depositary receipt programs. Prior to December 31, 2005 and at the time of our initial public offering, this threshold was 40% and our current ADSs program is near its full capacity. If we cannot obtain adequate funds to satisfy our capital requirements, we may need to limit our operations significantly, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

Inflation could increase our costs and adversely affect our results of operations.

        The Russian and Ukrainian economies have been characterized by high rates of inflation, which over the past few years have been mainly driven by weakening of national currencies, restrictions on foreign trade and acceleration in food prices.

        In 2014, the Bank of Russia implemented an inflation targeting program. As a result of this, inflation in Russia amounted to 5.4% in 2016, which was significantly lower as compared to 12.9% in 2015, according to the Federal Statistics Service. In 2017, inflation decreased to lower than 3% as compared to the target level of 4%. By the end of 2017, consumer inflation reached its historically lowest level of 2.5% year-to-year. The Bank of Russia plans to maintain inflation at the 4% target level in the long-term. To achieve this target, the Bank of Russia will more likely change main parameters of monetary policy. However, despite its plans to maintain inflation at the target level, there are risks of inflation increase due to the following factors:

•

possible unfreezing of monopolies' tariffs. During last 10 years tariffs of infrastructure monopolies significantly affected inflation parameters, and contributed more than 40% to the total price volatility in certain years;



•

import of inflation due to exchange rate of the Russian ruble. Cumulative effect of domestic prices change in response to change of exchange rate of the Russian ruble is defined as an effect of transferring dynamics of an exchange rate to prices, it has been salient during rubble depreciation in 2014 and 2015; and



•

low monetization of the Russian economy. The degree of monetization of the Russian economy is lower than in developed countries and in countries of the Eastern Europe. Attempts to increase the monetization of the Russian economy by raising money supply will likely lead to an increase in inflation due to the lack of confidence on the part of residents and non-residents in the Russian banking system.

        According to the State Statistics Service of Ukraine, in December 2017, the inflation index was 13.7% for 2017 (as compared to 12.4% for 2016). According to the National Bank of Ukraine latest outlook, the consumer price index will stabilize at 7.3% by the end of 2018.

        In addition, a further decline in global oil prices coupled with capital outflow from growing markets and depreciation of national currencies might cause a rise in inflation. High inflation levels may lead, inter alia, to increased marketing expenditure that could, in turn, affect our operating margins and profitability.

        At the end of 2015, 2016 and 2017, inflation in Belarus amounted to 12.0%, 10.6% and 4.6%, respectively.

        High rates of inflation in Russia, Ukraine and other countries of our operation could increase our costs and decrease our operating margins. See also "Item 5—Operating and Financial Review and Prospects—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Inflation."

        See also "—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble, as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our financial results" and "Item 11—Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

Table of Contents

Indentures relating to some of our notes contain, and some of our loan agreements and Sistema's loan agreements contain, restrictive covenants, which limit our ability to incur debt and to engage in various activities.

        Covenants in the agreement relating to our Eurobonds due 2023 limit our ability to create liens on our properties, merge or consolidate with another person or convey our properties and assets to another person. Additionally, the indentures governing our U.S. dollar-denominated notes due 2020 contain covenants limiting our ability to incur debt, create liens on our properties, enter into sale and lease-back transactions, merge or consolidate with another person or convey our properties and assets to another person, as well as our ability to sell or transfer any of our or our subsidiaries' GSM licenses for the Moscow, St. Petersburg, Krasnodar and Ukraine license areas. Some of our loan agreements contain similar and other covenants, including, in relation to the incurrence of indebtedness, creation of liens and disposal of assets. We may also incur additional credit obligations providing for similar covenants. Failure to comply with these covenants may cause a default and result in the debt becoming immediately due and payable, which would materially adversely affect our business, financial condition and results of operations.

        In addition, Sistema, which owns a controlling stake in MTS and consolidates our results in its financial statements, is subject to various covenants in its credit facilities. These covenants impose restrictions on Sistema and its restricted subsidiaries (including us) with respect to, inter alia, incurrence of indebtedness, creation of liens and disposal of assets. In its indentures, Sistema undertakes that it will not, and will not permit its restricted subsidiaries (including us) to, incur indebtedness unless a certain indebtedness level / EBITDA ratio is met. In addition to us, Sistema has various other businesses that require capital and, therefore, the consolidated Sistema group's capacity to incur indebtedness otherwise available to us could be diverted to its other businesses. Sistema may also enter into other agreements in the future that may further restrict it and its subsidiaries (including us) from engaging in these and other activities. We expect Sistema to exercise control over us in order for Sistema, as a consolidated group, to meet its obligations under its current and future financings and other agreements, which could materially limit our ability to obtain additional financing required for the implementation of our business strategy. The inability to implement our business strategy may have a material adverse effect on our financial condition and results of operations.

A change in control could have a material adverse effect on our financial condition and results of operations.

        Under the terms of our outstanding notes, if a change in control occurs, our noteholders will have the right to require us to redeem notes not previously called for redemption. The price we will be required to pay upon such event will be 101% of the principal amount of the notes, plus interest accrued prior to the redemption date. A change in control will be deemed to have occurred in any of the following circumstances:

•

with respect to the notes due 2020, any person acquires beneficial or legal ownership of, or control over, more than 50% of our issued shares, ownership of or control over more than 50% of the voting interests in our share capital or obtains the power to elect not less than half of our directors, provided that the following transactions would not be deemed to result in a change of control:



•

any acquisition by Sistema or its subsidiaries that results in the 50% threshold being exceeded;



•

any acquisition by us, our subsidiary or our employee benefit plan; and



•

a contribution by Sistema of all or part of its ownership interest in us into a partnership, joint venture or other indirect holding vehicle as long as any other person who is an owner of or party interested in that partnership, joint venture or other indirect holding vehicle

Table of Contents

does not acquire beneficial ownership of or control over more than 50% of our issued shares, does not acquire ownership of or control over more than 50% of the voting interests in our share capital and does not obtain the power to elect not less than half of our directors.

        Some of our loan agreements contain similar change of control provisions. If a change in control occurs, and our noteholders and other debt holders exercise their right to require us to redeem all of their notes or debt, such event could have a material adverse effect on our financial condition and results of operations.

        In addition, under certain of our debt agreements, an event of default may be deemed to have occurred and/or we may be required to make a prepayment if Sistema disposes of its stake in our company and a third party takes a controlling position in our company. The occurrence of any such event of default or failure to make any required prepayment, which leads to an event of default, could trigger cross default / cross acceleration provisions under certain of our other debt agreements. In such event, our obligations under one or more of these agreements could become immediately due and payable, which would have a material adverse effect on our business and our shareholders' equity. If Sistema were to dispose of its stake in us, our company may be deprived of the benefits and resources that it derives from Sistema, which could harm our business.

Risks Relating to Economic Risks in Our Countries of Operation

Economic instability in the countries where we operate could adversely affect our business.

        Since the dissolution of the Soviet Union in 1991, the economies of Russia and other countries where we operate have experienced periods of considerable instability. For example, GDP level significantly impacted basic commodity prices as was detected during the crisis in 2008 and 2009.

        In 2016, the decline in the GDP of Russia was 0.2%, compared to 3.7% in 2015, according to the Federal State Statistics Service. The Ministry of Economic Development revised its forecast for Russian GDP up to 2.1% in 2017 from the previous forecast of 2.0%, and its current forecast for the GDP of Russia for 2018, 2019 and 2020 is in the range of 2.1-2.3%, compared to just 1.5% in its previous forecast.

        In January 2018, the Ministry of Economic Development forecasted that the Russian economy would grow 1.4-1.8% in 2017, and not 2.1%, as previously forecasted. This rate corresponds with the monthly and quarterly data of the Federal State Statistics Service. The Ministry of Economic Development expects that the economy will accelerate to a rate of about 2% in 2018, and a budget surplus will be 1%.

        Any future economic downturns in Russia or the other countries where we operate, could lead to a decrease in demand for our services and, consequently, in our revenues, and negatively affect our liquidity position and ability to obtain further debt financing, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

The Russian banking system remains underdeveloped, the number of creditworthy banks in Russia is limited and another banking crisis could place severe liquidity constraints on our business.

        Russia's banking and financial services systems are less developed or regulated as compared to other countries, and Russian legislation relating to banks and bank accounts is subject to varying interpretations and inconsistent application. The August 1998 financial crisis resulted in the bankruptcy and liquidation of many Russian banks and almost entirely eliminated the developing market for commercial bank loans at that time. Many Russian banks currently do not meet international banking standards, and the transparency of the Russian banking sector in some respects still lags far behind internationally accepted norms. Aided by inadequate supervision by the regulators, certain banks do not

36

Table of Contents

follow existing CBR regulations with respect to lending criteria, credit quality, loan loss reserves or diversification of exposure. Furthermore, in Russia, bank deposits made by corporate entities are generally not insured.

        In recent years, there has been a rapid increase in lending by Russian banks, which has been accompanied by a deterioration in the credit quality of the borrowers. In addition, a robust domestic corporate debt market is leading Russian banks (including the banks with which we conduct banking transactions) to hold increasingly large amounts of Russian corporate ruble bonds in their portfolios, which is further deteriorating the risk profile of Russian bank assets. The serious deficiencies in the Russian banking sector, combined with the deterioration in the credit portfolios of Russian banks, may result in the banking sector being more susceptible to market downturns or economic slowdowns, including due to Russian corporate defaults that may occur during any such market downturn or economic slowdown. In addition, the CBR has from time to time revoked the licenses of certain Russian banks, which resulted in market rumors about additional bank closures and many depositors withdrawing their savings. Recently, a number of banks and credit institutions have lost their licenses due to the deficiency of capital and failure to meet the CBR requirements. In 2014-2017, for instance, the CBR revoked the licenses of a number of Russian banks for reasons associated with implementing high-risk lending policies, loss of liquidity and non-compliance with anti-money laundering legislation. A combination of these factors may result in a significant deterioration in the financial fundamentals of Russian banks, notably liquidity, asset quality and profitability.

        There is currently a limited number of sufficiently creditworthy Russian banks and few ruble denominated financial instruments in which we can invest our excess ruble cash. We hold the bulk of our excess ruble and foreign currency cash in Russian banks, including subsidiaries of foreign banks.

        In the event of a banking crisis, Russian companies may be subject to severe liquidity constraints due to the limited supply of domestic savings and the withdrawal of foreign funding sources that may occur during such crisis. Another banking crisis or the bankruptcy or insolvency of the banks from which we receive or with which we hold our funds could result in the loss of our deposits or affect our ability to complete banking transactions in Russia, which could have a material adverse effect on our business, financial condition and results of operations.

The physical infrastructure in Russia, Ukraine and the other countries where we operate is in poor condition, which could disrupt our normal business activities and adversely impact our results.

        The physical infrastructure in Russia, Ukraine and the other countries where we operate largely dates back to Soviet times and has not been always funded and maintained over the past years. Particularly affected are the rail and road networks, power generation and transmission systems, communication systems and building stock. For example, in August 2009, a major accident occurred at Russia's largest power plant, the Sayano-Shushenskaya hydroelectric power station, resulting in flooding of the engine and turbine rooms and the death of 75 people. Power generation from the station ceased completely following the incident, which led to a major power outage in the nearby residential areas and at certain industrial facilities as well as pollution of the rivers and soil as a result of an oil spill from the transformer.

        In addition, the road conditions throughout our countries of operation are poor with many roads not meeting minimum quality standards, causing disruptions and delays in the transportation of goods to and within these countries. The Russian and Ukrainian governments are actively considering plans to reorganize their national rail, electricity and communications systems. Any such reorganization may result in increased charges and tariffs while failing to generate the anticipated capital investment needed to repair, maintain and improve these systems. The deterioration of the physical infrastructure in Russia, Ukraine and the other countries where we operate harms the national economies, adds costs to doing business in these countries and generally disrupts normal business activities. These difficulties

37

Table of Contents

can impact us directly; for example, we keep portable electrical generators to help us maintain base station operations in the event of power outages. Further deterioration of the physical infrastructure in Russia, Ukraine and the other countries where we operate could have a material adverse effect on our business, financial condition and results of operations. In addition, the increased charges and tariffs that may result from the government reorganization may also have a material adverse effect on our business, financial condition and results of operations.

Fluctuations in the global economy may materially adversely affect the economies of the countries where we operate and our business in these countries.

        The economies of the countries where we operate are vulnerable to market downturns and economic slowdowns elsewhere in the world. As has happened in the past, financial problems or an increase in the perceived risks associated with investing in emerging economies could dampen foreign investment in Russia, Ukraine and the other countries where we operate, and businesses in these countries could consequently face severe liquidity constraints. Additionally, as Russia produces and exports large amounts of oil and gas, the Russian economy is especially vulnerable to the price of oil and gas on the world market and a decline in the price of oil and gas could negatively impact its economy. Recent military conflicts and international terrorist activity have significantly impacted the oil and gas prices globally, and pose additional risks to the Russian economy. Both Russia and Ukraine are also major producers and exporters of metal products and their economies are vulnerable to world commodity prices and the imposition of tariffs and/or anti-dumping measures by the United States, the European Union or other principal export markets.

        The disruptions recently experienced in the domestic and international capital markets have led to reduced liquidity and increased credit risk premiums for certain market participants and have resulted in a reduction of available financing. Companies located in emerging markets, including us, may be particularly susceptible to these disruptions and reductions in the availability of credit or increases in financing costs. To the extent that the current market downturn continues or worsens, it may lead to constraints on our liquidity and ability to obtain debt financing, which may have a material adverse effect on our business, financial conditions and results of operations.

Political and Social Risks

Political and governmental instability in Russia and other countries of our operations could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs.

        The political and economic situation in Russia has been negatively affected by the global financial crisis, the economic sanctions imposed by the United States and the European Union and the ongoing volatile economic conditions. Other countries where we operate may pose similar challenges, for example, Ukraine, where political tensions and uncertainty are continuing. See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations." Current and future political changes in Russia and the other countries where we operate, major policy shifts or a lack of consensus between the various branches of power and powerful economic groups could disrupt or reverse economic and regulatory reforms. This could, in turn, lead to further political instability or conflicts among powerful economic groups, which could have a material adverse effect on our business, financial condition, results of operations, prospects and the value of our shares and ADSs. A deterioration of the socio-political situation in Russia could also trigger an event of default under some of our loan agreements.

Potential conflict between central and regional authorities could create an uncertain operating environment hindering our long-term planning ability.

        The Russian Federation is a federation of units, consisting of republics, territories, regions, cities of federal importance and autonomous regions and districts. The delineation of authority and jurisdiction among the members of the Russian Federation and the federal government is, in many instances, unclear and remains contested. A lack of consensus between the federal government and local or regional authorities could result in the enactment of conflicting legislation at various levels and may lead to political instability. In particular, conflicting laws have been enacted in the areas of privatization, land legislation and licensing. Some of these laws, as well as governmental and administrative decisions implementing them and certain transactions consummated pursuant to them, have in the past been challenged in the courts, and such challenges may occur in the future. This lack of consensus may hinder our long-term planning efforts and create uncertainties in our operating environment, both of which may prevent us from effectively and efficiently implementing our business strategy.

        Additionally, ethnic, religious, historical and other divisions have, on occasion, given rise to tensions and, in certain cases, military conflict, which can halt normal economic activity and disrupt the economies of neighboring regions. The further intensification of violence, including terrorist attacks and suicide bombings, or its spread to other parts of Russia, could have significant political consequences, including the imposition of a state of emergency in some parts or the whole of Russia. Moreover, any terrorist attacks and the resulting heightened security measures are likely to cause disruptions to domestic commerce and exports from Russia. Any of these factors could materially adversely affect our business and the value of our shares and ADSs. In Ukraine, the political instability and the tensions in eastern Ukraine may also have negative effect on our business operations.

A deterioration in relations between Russia and other former Soviet republics, as well as other politically related disagreements and allegations between Russia and other countries and sanctions imposed as a result thereof, could materially adversely affect our business, financial condition, results of operations, prospects and the value of our shares and ADSs.

        Relations between Russia and certain other former Soviet republics are or have in the past been strained. For example, in August 2008, an armed conflict erupted between Russia and Georgia over the self-appointed republics South Ossetia and Abkhazia, culminating in Russia's recognition of their independence from Georgia The political and economic relationships between Ukraine and Russia have also been strained in recent years, see also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations" and "—Risks Relating to our Financial Condition—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble, as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our financial results."

        The United States and the European Union have imposed sanctions on certain Russian and Ukrainian persons and entities. No individual or entity within our group has been designated with sanctions introduced by either the United States or the European Union. However, additional designations may be made, or additional categories of sanctions may be created, at any time, and we can give no assurance that any member of our group, or individuals holding positions within our group, will not be affected by future sanctions designations.

        Non-compliance with any potential sanctions could result in, among other things, the inability of the relevant group entities to contract with the governmental authorities of the United States or the

decision-making and executive bodies of the European Union, or their agencies, potential civil or criminal liability for the sanctioned individuals and entities and their associates under the US and/or EU law, the imposition of significant fines and reputational damage.

        Further tensions between Russia and other countries and any escalation of the existing tensions, the imposition of further sanctions, or continued uncertainty regarding the scope thereof, could have a negative effect on the Russian economy, the financial condition of our partners and suppliers, our ability to conduct trade and financial transactions, our ability to obtain financing on commercially reasonable terms (or at all), and the level and volatility of the trading price of our shares and ADSs.

        The Ukrainian Cabinet of Ministers initiated adoption of the Law "On Sanctions" by the Verkhovna Rada of Ukraine which came into force on September 12, 2014. The law provides for special economic and other restrictive measures against foreign states, foreign legal entities and individuals involved in activities threatening the national security, sovereignty and territorial integrity of Ukraine and the rights and freedoms of its citizens. The law stipulates 25 types of sanctions which include, among others:

•

asset freezing;



•

temporary limitation of a right to use or dispose of property;



•

cancellation or suspension of licenses and other permits, including special permits for subsoil use;



•

prohibition to use radio frequency resources in Ukraine; and



•

termination or suspension of rendering telecommunications services or utilizing telecommunications networks of general use.

        A draft law expanding the list of sanctions, stipulated by the Law "On sanctions" was introduced on July 13, 2015. It includes, inter alia, the seizure of any assets of Russian proprietary rights and any assets or private property in case of social necessity in the interests of the state. In addition, the Presidential Decree No. 549/2015 dated September 16, 2015 approved the decision of the National Security and Defense Council of Ukraine dated September 2, 2015 "On the application of personal special economic and other restrictive measures (sanctions)," whereby the list of individuals and legal entities to which these sanctions applied for a one-year term was specified. The list of sanctions was extended several times during the period under review.

        Pursuant to the Law of Ukraine "On the legal status of martial law" dated June 8, 2015, military command together with military administrations are permitted to temporarily limit certain rights, freedoms and legal interests of individuals and legal entities within specific territories where martial law is introduced. On June 28, 2015, amendments to the Law of Ukraine "On licensing of certain types of economic activity" came into force expanding the terms of license cancellation, including adoption of an "act on documentary proof of control over licensee actions by other states, carrying out armed aggression against Ukraine or whose actions create preconditions either for military conflict or use of military force against Ukraine." With effect from January 1, 2018, the licensing of certain activities in the telecommunications sector has been canceled in accordance with the Law of Ukraine "On licensing of certain types of economic activity."

        Furthermore, the Law of Ukraine "On amendments to the Law of Ukraine "On the protection of economic competition" came into force and is aimed to improve the procedures for control over the concentration of economic entities, and provides for special economic and other restrictive measures to a concentration's participant according to the Law of Ukraine "On Sanctions."

        The Law of Ukraine "On Amendments to the Law of Ukraine "On the protection of economic competition" regarding the improvement of control over the concentration of economic entities" is

expected to be signed by the President of Ukraine and it will give the Antimonopoly Committee of Ukraine the right to refuse to consider applications for concentration submitted by companies included in the sanctions list. The draft law "On amendments to Article 9 of the Law of Ukraine "On State Registration of Legal Entities, Individual Entrepreneurs and Public Organizations" was introduced in Ukraine, which requires economic entities to publish information relating to their beneficial owners in the unified state register (in the event that the beneficial owner of the company is a resident of a country carrying out armed aggression against Ukraine). In addition, the draft law "On amendments to some legislative acts relating to labeling of products (or services) produced by suppliers tied with an aggressor country" stipulates that the suppliers of goods (or services) might be obliged to mark the advertising of products (or services) with the information on their ties with an aggressor country. The draft laws have not been considered by functional committee of the Verkhovna Rada and the Parliament of Ukraine yet.

        The Presidential Decree No. 133/2017 "On the decision of the National Security and Defense Council of Ukraine "On the imposition of personal special economic and other restrictive measures (sanctions)" dated May 17, 2017 imposed new sanctions and determined a new sanction list against 1,228 individuals and 468 legal entities. MTS Ukraine was not subject to these sanctions.

        According to that Decree:

•

mobile operators and providers of telecommunications services must restrict access to a number of Internet resources listed in the annexes to the Decree;



•

software usage of a number of legal entities listed in the annexes to the Decree is prohibited; and



•

rendering of telecommunications services and access to telecommunications networks is prohibited for a number of legal entities listed in the annexes to the Decree.

        In November 2016, NBU adopted a resolution that is aimed to, inter alia, impose restrictions on operations with persons and entities targeted by sanctions.

        On February 13, 2017, the Decree of the President of Ukraine No. 32/2017 provided the directions of legislative changes, that could lead to restriction of the use of software and telecommunications equipment produced in Russia and simplification for the regulators to access data from communication channels (for the purposes of the identification of service providers, blocking of certain information resources and facilitating the storage of telecommunications data by operators). These decisions may affect our operations to the extent that they allow access to information resources of Russian origin, using billing equipment and storing data from communication channels. Pursuant to this Decree, the draft law "On Amendments to the Law "On Sanctions" was submitted for public discussion on July 7, 2017, which proposes to impose additional sanctions, in particular, with regard to the prohibition or restriction of the use of Russian software on sensitive infrastructure objects, as well as software developed by companies that are subject to sanctions. This draft law was adopted by the Cabinet of Ministers of Ukraine on February 14, 2018.

        In March 2017, pursuant to the Resolution of the National Security and Defense Council of Ukraine dated March 15, 2017 "On the Imposition of Personal Special Economic and Other Restrictive Measures (Sanctions)," as approved by the Decree of the President of Ukraine No. 63/2017, NBU introduced sanctions aimed at Ukrainian subsidiaries of a number of Russian banks in order to prohibit financial operations, including any payments of dividends, in favor of the parent banks. This supplements a set of measures in respect of Russian entities subject to the sanctions introduced in accordance with the NBU Board Resolution No. 654 dated October 1, 2015 "On Ensuring the Implementation and Monitoring of the Effectiveness of Personal Special Economic and Other Restrictive Measures (Sanctions) and the Resolution No. 399 dated November 1, 2016 "On

Amendments to the Resolution of the Board of the National Bank of Ukraine No. 654 dated October 1, 2015."

        The Administration of the State Service of Special Communications and Information Protection of Ukraine developed a draft government resolution which provides further actions of authorized state bodies when blocking access to the information resources designated in the sanction list. The project provides, inter alia, connection to operators' networks of equipment to monitor the blocked information resources. Regarding the draft law special equipment might be connected to the operator's network, which may lead to additional costs. The document is under consideration.

        In June 2017, the Board of the National Bank of Ukraine adopted Resolution No. 46 "On Amendments to the Resolution of the Board of the National Bank of Ukraine No. 654 dated October 1, 2015." The Resolution set out the requirements for banks dealing with persons designated in the sanctions list, in particular, prohibiting them from executing payment documents of any customers designated in the sanction list and transferring any funds to their accounts.

        On October 5, 2017, the Law of Ukraine "On the basic principles of ensuring the cybersecurity of Ukraine" was adopted. The law provides the requirements and procedures for identifying critical infrastructure objects to ensure cybersecurity. All enterprises in the field of information and communications technologies might be recognized as objects of critical infrastructure that can bear the risks of additional costs and additional responsibility for ensuring cybersecurity.

        On October 19, 2017, The Ministry of Economic Development and Trade developed and submitted for public discussion the draft law "On Amendments to the Law of Ukraine "On foreign economic activities," which proposed to grant the Ministry of Economic Development and Trade a right to suspend foreign economic activities for a period of one year according to a submission of the Security Service of Ukraine if subjects of foreign economic activity carry out activities connected with the financing of terrorism and encroachment of national interests, national security and territorial integrity of Ukraine.

        There is still significant uncertainty regarding how these measures might affect VF Ukraine and our group, the extent and timing of any further sanctions, or the ultimate impact of these sanctions on our operations. These measures and any further measures and sanctions may have a negative effect on our business, financial condition, results of operations, prospects and the value of our shares and ADSs.

Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations.

        Economic crisis, deterioration of key aspects of the economy and the lack of investment into the social infrastructure, has, amongst other things, led to the instability of the political situation in Ukraine where we have significant operations. Furthermore, the refusal of the Ukrainian Government to enter into an association agreement with the European Union in November 2013, incited mass protests in Kiev and other regions of the country. These protests caused, amongst other things, a downgrade of Ukraine's international ratings and significant depreciation of the national currency, see "—Risks Relating to our Financial Condition—Changes in the exchange rate of local currencies in the countries where we operate against the Russian ruble could adversely impact our revenues reported in

Russian rubles as well as changes in the exchange rate of the Russian ruble and local currencies against the U.S. dollar and/or euro could adversely impact our financial results."

        On March 16, 2014, a referendum in favor of joining the Russian Federation was held in Crimea with the consequent declaration of independence Crimea from Ukraine and the accession to the Russian Federation by the parliament of Crimea.

        The armed conflict in Eastern Ukraine that has taken place since April 2014 has destabilized the region and caused uncertainty in our operation in the region of the armed conflict. It has also led to damage of our network equipment in the region followed by related losses. Should the economic and political situation in Eastern Ukraine become further destabilized, should local operators enter the market or other external factors affect the region, this may adversely affect our business, financial condition, corporate image and results of operations as well as cause regulatory uncertainties.

        These events have resulted in heightened tensions between Ukraine and the Russian Federation and have strained relationships of the Russian Federation with the United States and the European Union, which may adversely impact our business. Furthermore, should the tensions between the Russian Federation and Ukraine continue or increase, or should the economic, social and political situation in Ukraine become further destabilized, our business interests in Ukraine and other impacted regions may be adversely affected or targeted. The continued impact of these events and any continuing or escalating military action, public protests, unrest, political instability or further sanctions could have a further adverse effect on our business in Ukraine, our financial condition and reputation.

        See also "—A deterioration in relations between Russia and other former Soviet republics, as well as other politically related disagreements and allegations between Russia and other countries and sanctions imposed as a result thereof, could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

Crime and corruption could disrupt our ability to conduct our business and thus materially adversely affect our operations.

        The political and economic changes in recent years in the countries where we operate have resulted in significant dislocations of authority. In addition, the local and international press have reported high levels of corruption, including the bribing of officials for the purpose of initiating investigations by government agencies. Press reports have also described instances in which government officials engaged in selective investigations and prosecutions to further the commercial interests of certain government officials or certain companies or individuals. Additionally, some members of the media in the countries we operate in regularly publish disparaging articles in return for payment. The depredations of organized or other crime or demands of dishonest officials could result in negative publicity, disrupt our ability to conduct our business and could thus materially adversely affect our business, financial condition, results of operations and prospects.

        Actions of fraudsters aimed against subscribers cause additional risks for operators. Despite our efforts to detect and prevent fraud, some forms of rendering services (for example, offering payments via external Internet sources) might entail risks of fraudulent charge-offs from subscribers' personal accounts. Such fraud actions could negatively affect our reputation and lead to an increase in subscriber churn, which could materially adversely affect our business, financial condition, results of operations and prospects.

Social instability could increase support for renewed centralized authority, nationalism or violence and thus materially adversely affect our operations.

        The failure of the government and many private enterprises to pay full salaries on a regular basis and the failure of salaries and benefits generally to keep pace with the rapidly increasing cost of living

have led in the past, and could lead in the future, to labor and social unrest. Labor and social unrest may have political, social and economic consequences, such as increased support for a renewal of centralized authority; increased nationalism, including restrictions on foreign involvement in the economies of the countries where we have operations; and increased violence. An occurrence of any of the foregoing events could restrict our operations and lead to the loss of revenues, materially adversely affecting our operations. See also "—Political instability in Ukraine could have a material adverse effect on our operations in Ukraine and on our business, financial condition and results of operations."

Legal Risks and Uncertainties

Weaknesses relating to the legal system and legislation in the countries where we operate create an uncertain environment for investment and business activity, which could have a material adverse effect on the value of our shares and ADSs.

        Each of the countries we operate in is still developing the legal framework required to support the market economy. The following risk factors relating to these legal systems create uncertainties with respect to the legal and business decisions that we make, many of which do not exist in countries with more developed market economies:

•

inconsistencies between and among the constitution, federal and regional laws and subordinate legislation (presidential decrees and governmental, ministerial and local orders, decisions and resolutions) and other acts;



•

the lack of judicial and administrative guidance on interpreting certain legislation as well as conflicting interpretations of supreme general jurisdiction and arbitrazh courts;



•

the relative inexperience of judges and courts in interpreting certain aspects of legislation;



•

the lack of an independent judiciary;



•

a high degree of discretion on the part of governmental authorities, which could result in arbitrary actions such as suspension or termination of our licenses; and



•

poorly developed bankruptcy and liquidation procedures and court practice that create possibilities of abuse.

        The recent nature of much of the legislation in the CIS countries, the lack of consensus about the scope, content and pace of economic and political reform and the rapid evolution of these legal systems in ways that may not always coincide with market developments place the enforceability and underlying constitutionality of laws in doubt and result in ambiguities, inconsistencies and anomalies. In addition, legislation in these countries often contemplates implementing regulations that have not yet been promulgated, leaving substantial gaps in the regulatory infrastructure. All of these weaknesses could affect our ability to enforce our rights under our licenses and contracts, or to defend ourselves against claims by others. Moreover, it is possible that regulators, judicial authorities or third parties may challenge our internal procedures and bylaws, as well as our compliance with applicable laws, decrees and regulations.

The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations.

        If we are unable to protect our business entities in the countries in which we operate from the withdrawal or suspension or regulatory scrutiny, this may adversely affect our business, financial condition and results of operations. For example, in June 2012, the authorities of the Republic of Uzbekistan began audits of the financial and operating activities of our wholly owned subsidiary, Uzdunrobita. Further various claims for violation of tax, antimonopoly and industry legislation were made against Uzdunrobita, which resulted in significant amounts of fines and penalties, revocation of

44

Table of Contents

all licenses and suspension of services. Total amount of damages was calculated and determined on the basis of all the aforementioned claims against Uzdunrobita and amounted to approximately RUB 18,375 million payable in equal installments over eight months.

        Uzdunrobita paid two scheduled installments in November and December 2012 totaling approximately RUB 4,583.4 million. On January 14, 2013, further to its partial payment of the third installment due in January 2013 totaling approximately RUB 481 million and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the grounds of its inability to meet further obligations.

        On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated a liquidation process. Uzdunrobita was later liquidated. In 2012, we filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes ("ICSID"), part of the World Bank Group, in Washington, D.C.

        On July 31, 2014, we and the Republic of Uzbekistan signed a settlement agreement (the "Settlement Agreement") and MTS agreed to reenter the Uzbekistan market through a joint enterprise with MTS holding a 50.01% in the charter capital of the joint enterprise, while the remaining 49.99% belongs to a state-owned unitary enterprise established and managed by the State Committee for Communications, Development of Information Systems and Telecommunications Technologies of the Republic of Uzbekistan. The Settlement Agreement is governed by English law and provides for the resolution of any disputes arising out of the Settlement Agreement in the International Court of Arbitration under International Chamber of Commerce in Paris.

        On September 24, 2014, in accordance with the Settlement Agreement, the authorities of the Republic of Uzbekistan granted the joint enterprise 2G, 3G and LTE licenses, provided necessary frequencies and numbering capacity, fostered entrance into lease agreements for communication channels and issued all permissions required to the joint enterprise so it could operate and offer full telecommunications services throughout Uzbekistan. The joint enterprise has also received guaranties for investment protection and return of investments in accordance with the laws of the Republic of Uzbekistan.

        In November 2014, ICSID discontinued international arbitration proceedings between MTS and the Republic of Uzbekistan following the submission of a joint application by both parties.

        On December 1, 2014, the joint enterprise, named UMS, launched sales of SIM cards through its proprietary network of 20 stores and through another 230 independent locations throughout Uzbekistan and started provision of 2G/3G telecommunications services on the entire territory of Uzbekistan.

        On August 5, 2016, we sold our 50.01% stake in UMS to the State Unitary Enterprise Centre of Radio Communication, Radio Broadcasting and Television of the Ministry of Development of Information Technologies and Communications of the Republic of Uzbekistan. The loss on disposal of investment in Uzbekistan was recorded in the financial report for the third quarter of 2016. See Note 27 to our audited consolidated financial statements.

The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations.

        In December 2010, the Group suspended its operations in Turkmenistan following notification by the Ministry of Communications of Turkmenistan of a decision to suspend licenses held by BCTI, the Group's wholly owned subsidiary in Turkmenistan, initially for a period of one month starting from December 21, 2010, and then permanently.

        On May 24, 2012, we concluded an agreement with the state-owned telecom operator Turkmentelekom relating to our terms of operations in Turkmenistan, which resulted from negotiations between the Turkmenistan government and ministries. The agreement had a five-year term and could be extended for the following five years, provided certain terms and conditions are satisfied. Under this agreement, we were obliged to pay Turkmentelekom a monthly amount calculated as 30% of our net profit in Turkmenistan based on accounting rules of Turkmenistan.

        On July 25, 2012, we, our subsidiary BCTI, the Republic of Turkmenistan, the Ministry of Communications of Turkmenistan, the state-owned company, Turkmentelecom, and a mobile operator, Altyn Asyr, signed a settlement agreement (which included the dismissal of all international lawsuits) concerning the suspension of our operations in Turkmenistan in December 2010.

        In August 2012, we restarted our mobile communication network in Turkmenistan and resumed providing services to subscribers who had not canceled their contracts. Since October 1, 2012 we resumed our operations in Turkmenistan entirely and started entering into contracts with new subscribers.

        On September 29, 2017, we announced that we were compelled to suspend communication services in Turkmenistan from 00:00 September 29, 2017, due to the actions of Turkmenistan, the Ministry of Communications of Turkmenistan, the state-owned telecommunications company, Turkmentelekom, and its wholly-owned subsidiary, Altyn Asyr, the state owned mobile operator in Turkmenistan. These actions resulted in the disconnection of international and long-distance zonal communication services and Internet access.

        Although our license for communication services in Turkmenistan is valid until July 26, 2018, we currently remain unable to operate in the country and are pursuing our legal remedies.

Russian and Ukrainian companies can be forced into liquidation on the basis of formal non-compliance with certain legal requirements.

        Certain provisions of Russian law may allow government authorities to seek a court order for the liquidation of a Russian legal entity on the basis of its formal non-compliance with certain requirements during formation, reorganization or during its operation.

        For example, under Russian corporate law, if the net assets of a Russian joint stock company calculated on the basis of Russian accounting standards are lower than its charter capital as at the end of its third or any subsequent financial year, the company must either decrease its charter capital or be placed in liquidation. If the company fails to comply with these requirements, governmental or local authorities can seek the involuntary liquidation of such company in court, and the company's creditors will have the right to accelerate their claims or demand early performance of the company's obligations as well as demand compensation of any damages.

        The existence of negative assets may not accurately reflect the actual ability to pay debts as they fall due. Many Russian companies have negative net assets due to very low historical asset values reflected on their Russian accounting standards balance sheets; however, their solvency, i.e., their ability to pay debts as they fall due, is not otherwise adversely affected by such negative net assets. Some Russian courts, in deciding whether or not to order the liquidation of a company for having negative

46

---

Table of Contents

net assets, have looked beyond the fact that the company failed to fully comply with all applicable legal requirements and have taken into account other factors, such as the financial standing of the company and its ability to meet its tax obligations, as well as the economic and social consequences of its liquidation. Nonetheless, creditors have the right to accelerate claims, and file damages claims, and governmental or local authorities may seek the liquidation of a company with negative net assets.

        Courts have, on rare occasions, ordered the involuntary liquidation of a company for having net assets less than the minimum charter capital required by law, even if the company had continued to fulfill its obligations and had net assets in excess of the minimum charter capital at the time of liquidation.

        The amount of net assets in accordance with the local accounting standards of some of our subsidiaries is less than the minimum charter capital required by law. Although these subsidiaries continue to meet all of their obligations to creditors, there is a minimal risk of their liquidation while the net assets remain below the minimum legal requirements.

        There have also been cases in the past in which formal deficiencies in the establishment process of a Russian legal entity or non-compliance with provisions of Russian law have been used as a basis to seek the liquidation of a legal entity. Weaknesses in the Russian legal system create an uncertain legal environment, which makes the decisions of a Russian court or a governmental authority difficult, if not impossible, to predict. If involuntary liquidation were to occur, such liquidation could lead to significant negative consequences for our group. Ukrainian law also contains provisions similar to Russian law, whereby a company's failure to comply with certain legal requirements concerning its formation, net assets or operation may be grounds for its liquidation.

Insufficient adherence to the independence and competitiveness of the judicial process, the difficulty of enforcing court decisions and governmental discretion in enforcing claims could prevent us or holders of our securities from obtaining effective redress in a court proceeding.

        The judicial bodies in the countries where we operate are not always completely independent or immune from economic and political influences, and are often understaffed and underfunded. Judges and courts are often inexperienced in the area of business, corporate and industry (telecommunications) law. Judicial precedents generally have no binding effect on subsequent decisions, and not all court decisions are readily available to the public or organized in a manner that facilitates understanding. The judicial systems in these countries can also be slow or unjustifiably swift.

        Enforcement of court orders can, in practice, be very difficult to achieve. All of these factors make judicial decisions in these countries difficult to predict and effective redress uncertain. Additionally, court claims are often used in furtherance of political and commercial aims or infighting. We may be subject to such claims and may not be able to receive a fair hearing. Additionally, court orders are not always enforced or followed by law enforcement agencies. Furthermore, recognition and enforcement of arbitral awards in countries where we operate is subject to compliance with corresponding rules of civil procedure and applicable laws, and courts in the countries where we operate may interpret applicable regulations in a manner which would result in denial of such recognition and enforcement.

        These uncertainties also extend to property rights. For example, during Russia and Ukraine's transformation from centrally planned economies to market economies, legislation has been enacted in both countries to protect private property against uncompensated expropriation and nationalization.

        However, there is a risk that due to the lack of experience in enforcing these provisions and due to political factors, these protections would not be enforced in the event of an attempted expropriation or nationalization. Expropriation or nationalization of any of our entities, their assets or portions thereof, potentially without adequate compensation, would have a material adverse effect on our business, financial condition, results of operations and prospects.

47

Table of Contents

Selective or arbitrary government action could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Governmental authorities in the countries where we operate have a high degree of discretion and, at times, act selectively or arbitrarily, without hearing or prior notice, and sometimes in a manner that is inconsistent with legislation or influenced by political or commercial considerations.

        Selective or arbitrary governmental actions have reportedly included the denial or withdrawal of licenses, sudden and unexpected tax audits and claims, criminal prosecutions and civil actions. Federal and local government entities have also used ordinary defects in matters surrounding share issuances and registration as pretexts for court claims and other demands to invalidate such issuances and registrations or to void transactions. Moreover, the government also has the power in certain circumstances, by regulation or government acts, to interfere with the performance of, nullify or terminate contracts.

        In addition, the Russian tax authorities have brought tax evasion claims relating to Russian companies' use of tax-optimization schemes, and press reports have speculated that these enforcement actions have been selective. Selective or arbitrary government action, if directed at us, could have a material adverse effect on our business, financial condition, results of operations and prospects.

Failure to comply with existing laws and regulations or to obtain all approvals, authorizations and permits required to transmit television channels or operate telecommunications equipment, or the findings of government inspections or increased governmental regulation of our operations, could result in a disruption in our business and substantial additional compliance costs and sanctions.

        Our operations and properties are subject to regulation by various government entities and agencies in connection with obtaining and renewing various licenses, approvals, authorizations and permits, as well as with ongoing compliance with existing laws, regulations and standards. Regulatory authorities exercise considerable discretion in matters of enforcement and interpretation of applicable laws, regulations and standards, the issuance and renewal of licenses, approvals, authorizations and permits and in monitoring licensees' compliance with the terms thereof. Russian authorities have the right to, and frequently do, conduct periodic inspections of our operations and properties throughout the year. Any such future inspections may conclude that we or our subsidiaries have violated laws, decrees or regulations, and we may be unable to refute such conclusions or remedy the violations. See also "—The regulatory environment for telecommunications in Russia, Ukraine and other countries where we operate or may operate in the future is uncertain and subject to political influence or manipulation, which may result in negative and arbitrary regulatory and other decisions against us on the basis of other than legal considerations and in preferential treatment for our competitors."

        Primarily due to delays in the issuance of permits, approvals and authorizations by regulatory authorities, it is frequently not possible to procure all of the permits for each of our base stations or other aspects of our network before we put the base stations into commercial operation or to amend or maintain all of the permits when we make changes to the location or technical specifications of our base stations. At times, there can be a significant number of base stations or other communications facilities and other aspects of our networks for which we do not have final permits to operate and there can be delays in obtaining the final permits, approvals and authorizations for particular base stations or other communications facilities and other aspects of our networks. Furthermore, we are constantly in the process of registration and re-registration of ownership over certain infrastructure facilities, for example, MGTS carries out measures aimed at registration of ownership rights to the cable line structures (CLS). At the same time, MGTS is not insured against the risks of challenging the ownership rights by third parties. MGTS performs legal registration of its ownership rights to minimize the risk. In case of receiving reasonable claims, MGTS reconciles cable line objects to distinguish the ownership rights. MGTS is ready to assert its rights to CLS in court when necessary.

        In addition, we may be unable to transmit certain television channels if entities that provide television content to us do not possess the requisite licenses. In case such providers of television content do not obtain the required licenses, or have their existing licenses suspended or terminated, our selection of potential television channels for transmission could be significantly limited. The Federal Law No. 257 "On Amending Federal Law "On Mass Media" and Federal Law "On Communications" dated July 13, 2015 introduced a number of amendments to the national mandatory free television channels list. Requirements on sequence of channels, sound and image quality and signal reception points of national mandatory free television channels were adopted in September 2015. The inability of operators to comply with such requirements may lead to suspension or termination of a license.

        Furthermore, we could be subject to fines and other penalties, including forced suspension of our cable network operators' activity for up to 90 days. In some cases of our service provision (for example, those employing GPON technology) power failures in subscribers' households may lead to non-compliance with rules regulating local telephony communication services. Any of these consequences could have a material adverse effect on our business, financial condition and results of operations.

        Our failure to comply with existing laws and regulations of the countries where we operate or to obtain all approvals, authorizations and permits required to operate telecommunications equipment, or the findings of government inspections including the State Labor Inspection Service may result in the imposition of fines or penalties or more severe sanctions including the suspension, amendment or termination of our licenses, approvals, authorizations and permits, or in requirements that we cease certain of our business activities, or in criminal and administrative penalties applicable to our officers.

        Moreover, an agreement or transaction entered into in violation of law may be invalidated and/or unwound by a court decision. Any such decisions, requirements or sanctions, or any increase in governmental regulation of our operations, could result in a disruption of our business and substantial additional compliance costs and could materially adversely affect our business, financial condition, results of operations and prospects. In addition, we may assume risks of potential claims from subscribers and regulating authorities regarding former activities of the acquired or merged businesses.

        Generally, communication networks are vulnerable to physical or software break-ins, viruses, unauthorized interferences and similar events. Should such events occur with respect to our network elements, we may become subject for additional inspection by the regulatory authorities. Although we obtain all necessary permissions and certificates for the operation of our equipment and provide measures to protect confidential information, our failure to fully comply with all legislation requirements could result in the imposition of fines or penalties, additional government regulations, substantial additional compliance costs, disruption of our business including its suspension or termination, and other adverse effects.

        In addition, in 2015 the Prosecutor General's Office of Ukraine started criminal proceedings on the fact of "unauthorized intervention" in the operation of MTS Ukraine telecommunications network in Crimea on March 15 and 16, 2014. The outcome of the investigation is currently unclear. Possible legal risks or risks concerning our license terms and conditions arising from the proceedings might adversely affect our business, financial condition and results of operations.

The level of development of corporate and securities laws and regulations in Russia could limit our ability to attract future investment.

        The regulation and supervision of the securities market, financial intermediaries and issuers are less developed in Russia than, for example, in the United States and Western Europe. Securities laws, including those relating to corporate governance, insider trading, disclosure and reporting requirements, are relatively new, while other laws concerning anti-fraud and directors' and officers' liabilities remain

underdeveloped. The Russian securities market is regulated by several state authorities, which poses certain risks.

        In addition, Russian corporate and securities rules and regulations can change rapidly, which may materially adversely affect our ability to conduct capital markets transactions. The regulatory requirements imposed on Russian issuers may lead to delays in the placement of securities and access to capital markets. It is often unclear whether or how regulations, decisions and letters issued by the various regulatory authorities apply to us. As a result, we may be subject to fines and/or other enforcement measures despite our best efforts at compliance, which could have a material adverse effect on our business, financial condition and results of operations.

        Furthermore on July 1, 2016, provisions of the Federal Law No. 210 stipulating the new procedure for corporate actions became effective which, inter alia, provides for a possibility of remote participation at general meetings of security holders (e-voting) for those shareholders who hold their shares either directly on a share register or through a depositary. This new procedures may lead to delays in voting process and inconsistencies and may entail additional risks due to their novelty to the Russian market.

There is insufficient minority shareholder protection in Russia.

        Minority shareholder protection under Russian law principally derives from (a) supermajority shareholder approval requirements for certain corporate actions, (b) the ability of a shareholder to demand that the company purchase the shares held by that shareholder if that shareholder voted against or did not participate in voting on certain types of actions, (c) the ability of a shareholder to sell his shares at a fair price when the control is changed, the company is acquired at a price determined in accordance with the requirements of the current legislation, (d) shareholders' right to challenge decisions of the company's management bodies in certain circumstances, and (e) shareholders' right to challenge transactions which caused company's loss. Companies are also required under Russian law to obtain the approval of disinterested shareholders for certain transactions with interested parties. In practice, enforcement of these protections has not always been effective. Shareholders of some companies have suffered as a result of fraudulent bankruptcies initiated by hostile creditors.

        The supermajority shareholder approval requirement is met by a vote of 75% of all voting shares that are present at a shareholders' meeting. Thus, controlling shareholders owning slightly less than 75% of outstanding shares of a company may have a 75% or more voting power if certain minority shareholders are not present at the meeting. In situations where controlling shareholders effectively have 75% or more of the voting power at a shareholders' meeting, they are in a position to approve amendments to the charter of the company or significant transactions including asset transfers, which could be prejudicial to the interests of minority shareholders. It is possible that our controlling shareholder in the future may not operate us and our subsidiaries for the benefit of minority shareholders, and this could have a material adverse effect on the value of our shares and ADSs.

        While the Federal Law on Joint Stock Companies provides that shareholders owning not less than 1% of the company's stock may bring an action for damages caused to a company by its CEO, member of the Board of Directors or its Management Board and certain other officials acting on behalf of the company, minority shareholders may have difficulties with proving such damages with the court and as a consequence their claims may be denied by the court. In 2009, legislation was adopted which contemplates class action litigation and in 2015 mechanism of class action regarding corporate disputes was introduced. Although there have been several disputes in the past few years, Russian courts do not have a clear and consistent approach in regards to class action litigation. In addition, the issue of claims by shareholders against the company to compensate the shareholders for their losses is not clearly regulated by the current legislation.

        Accordingly, your ability to pursue legal redress against us may be limited, reducing the protections available to you as a holder of our shares and ADSs.

According to Russian legislation, shareholders/participants of Russian companies have an opportunity to demand either liquidation of a company in a judicial proceeding or exclusion of other shareholder/ participant (except for public joint stock companies) from the company.

        According to the amendments to the Civil Code of the Russian Federation, which came into effect on September 1, 2014, shareholders and participants of Russian companies have, inter alia, the following rights, which can be executed via judicial proceedings:

•

to demand the liquidation of a company in case of failure to achieve a corporate purpose for which it was created, including a case when an operation of a company becomes impossible or is substantially hampered; and



•

to demand exclusion of a shareholder or a participant (except for the public joint stock companies, including MTS) whose actions/inactivity either cause significant harm or hampers the company's operations.

        In this regard, we cannot rule out the possibility of such claims being filed against us. Should such claims be brought, this may have a negative impact on our business, financial condition and results of operations.

Shareholder liability under Russian legislation could cause us to become liable for both obligations of our subsidiaries and losses of the legal entities in which we have a practical possibility of determining actions.

        The Civil Code of the Russian Federation, the Joint Stock Companies Law and the Federal Law "On Limited Liability Companies" generally provide that shareholders in a Russian joint stock company or members of a limited liability company are not liable for the obligations of the company and bear only the risk of loss of their investment. This may not be the case, however, when one entity is capable of determining decisions made by another entity. The entity capable of determining such decisions is deemed an "effective parent." The entity whose decisions are capable of being so determined is deemed an "effective subsidiary." The effective parent bears joint and several liability for transactions concluded by the effective subsidiary in carrying out its decisions or decisions made with its consent. However, joint and several responsibility of the effective parent is excluded in case of voting of the effective parent on the approval of the transaction at a general shareholders' meeting of the effective subsidiary, as well as the approval of the transaction by the body of the effective parent, if the need for such approval is envisaged in the charter of the effective subsidiary and/or the effective parent. In addition, an effective parent is secondarily liable for an effective subsidiary's debts if an effective subsidiary becomes insolvent or bankrupt resulting from the action or failure to act of an effective parent. This is the case no matter how the effective parent's ability to determine decisions of the effective subsidiary arises.

        Accordingly, we could be liable in some cases for debts of our subsidiaries and losses of the legal entities to the extent that we had any power of determining such subsidiaries' actions that caused such losses. This liability could have a material adverse effect on our business, results of operations and financial condition.

Shareholder rights provisions under Russian law could impose additional obligations and costs on us, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Russian law provides that shareholders that vote against or did not participate in voting on certain matters have the right to sell their shares to the company at market value in accordance with Russian law. The decisions that trigger this right to sell shares include:

•

decisions with respect to a reorganization;



•

the approval by shareholders of a "major transaction," which involves property in excess of 50% of the balance sheet value of the company's assets calculated according to Russian accounting standards, regardless of whether the transaction is actually consummated (including those which are simultaneously interested-party transactions), except for transactions undertaken in the ordinary course of business;



•

the amendment of our charter in a manner that limits shareholder rights;



•

the amendment of our charter in a manner that excludes reference to the entity's public status, approved simultaneously with a decision on applying to the CBR on release from obligation to disclose information under the laws of the Russian Federation on securities; and



•

a decision on applying for delisting of shares and convertible securities from a stock exchange.

        For example, during 2015-2017 we repurchased MTS ordinary shares, for more details see "Item 16E—Purchases of Equity Securities by the Issuer and Affiliated Purchasers." Our obligation to purchase shares in these circumstances, which is limited to 10% of the company's net assets calculated in accordance with Russian accounting standards at the time the matter at issue is voted upon, could have a material adverse effect on our business, financial condition, results of operations and prospects. Under Russian law, if we are unable to sell the repurchased shares at a price equal to or exceeding the market price within one year of the date of repurchase, we will have to reduce our charter capital accordingly.

The Strategic Foreign Investment Law imposes certain restrictions on us and our existing and potential foreign shareholders, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        On May 7, 2008, the Federal Law "On the Procedure for Foreign Investment in Commercial Organizations of Strategic Importance for the Defense and Security of the State," or the Strategic Foreign Investment Law, came into force in Russia. This law sets forth certain restrictions relating to foreign investments in Russian companies of "strategic importance." Among others, companies with a dominant position in the Russian telecommunications market are considered to be strategically important and foreign investments in such companies are subject to regulations and restrictions to these companies set out by the Strategic Foreign Investment Law. For purposes of the Strategic Foreign Investment Law, a mobile telecommunications provider is deemed to be dominant if its market share in the Russian market exceeds 25%, as may be determined by FAS. In addition, a company may be considered to be strategically important due to our offering of services involving the use of cryptographic technologies.

        Starting from the effective date of the Strategic Foreign Investment Law, a foreign investor (including Russian citizens having foreign citizenship according to the amendments which came in force on July 1, 2017) seeking to obtain direct or indirect control over a strategically important company is required to have the respective transaction pre-approved by a special governmental commission on control of foreign investments. On December 6, 2014, the amendments to the Strategic Foreign Investment Law came into effect. The law stipulates that foreign investors are obliged to obtain prior approval of transactions envisaging the acquisition of right of ownership, possession or use of property

52

classified as the fixed production assets of a strategic company and the value of which represents 25% or more of the balance sheet value of the assets of such company as of the last reporting date, according to accounts. In addition, foreign investors are required to notify this authorized governmental body about any transactions undertaken by them resulting in the acquisition of 5% or more of the charter capital of strategically important companies. Within 180 days from the effective date of the Strategic Foreign Investment Law, foreign investors having 5% or more of the charter capital of strategically important companies were required to notify the authorized governmental body about their current shareholding in such companies.

        Commencing December 6, 2014, a foreign investor is also obliged to notify the authorized governmental body about the fact of conducting the pre-approved transactions. With effect from July 1, 2017, according to the amendments, offshore companies (and companies under their control) are prohibited from obtaining control over a strategically important company and are obliged to have any acquisition of 25% or more of right of ownership of voting shares pre-approved. According to the amendments that came into force on July 1, 2017, certain sanctions may be imposed in respect of such transactions conducted without notification, for example, a deprivation of the foreign investor of any voting rights at a shareholders' meeting of strategically important companies through judicial proceedings brought by an authorized governmental body.

        As we are classified as a strategically important company, our current and future foreign investors are subject to the notification requirements described above and our current and potential investors may be limited in their ability to acquire a controlling stake in, or otherwise gain control over, us. Such increase in governmental control or limitation on foreign investment could impair the value of your investment and could hinder our access to additional capital.

Regulatory changes in Russia, including the reduction of settlement rate, regulation of other inter-carrier and subscriber tariffs and others, as well as regulatory changes at the international level may have a material adverse effect on our financial condition and results of operations.

        Following an amendment to the Federal Law on Communications, which became effective July 1, 2006, fixed-line operators began charging their subscribers for calls to mobile phone users and started to transfer a percentage of the charge to mobile operators terminating such calls. The percentage transferred to mobile operators is established by the regulator and is known as the "settlement rate."

        The Ministry of Communications and Mass Media is considering altering the approach to inter-carrier settlements in Russia and the subsequent lowering of the settlement rate. Any reduction of the settlement rate by the regulator could have a negative impact on our average monthly service revenues per subscriber and margins. In September 2013, the Government commission on telecommunications supported the proposal of the Ministry of Communications and Mass Media to simplify the process of traffic transmission within one sub-federal region, as well as to simplify the process of traffic transmission within the voice and data networks while transmitting voice information within one sub-federal region of the Russian Federation. The exact changes to the current regulations may be significant, including the regulation of interconnect leading to operators' inability to determine the autonomous pricing of interconnect rates.

        In November 2014, the Government of Russia considered a proposal on reconsideration of the interconnect regulation approach submitted by the Ministry of Communications. It is unclear yet how this proposal may be implemented, however it may potentially lead to a reduction in traffic transmission revenues and an increase in traffic transmission costs. The final decision on the implementation of this proposal has not been made yet.

        The agreement on the conditions of inter-carrier mutual settlements while delivering international communication services in CIS-countries was signed on the CIS Heads of Government Council meeting held in Dushanbe on October 30, 2015 (the "Agreement"). The enforcement of certain provisions of

53

Table of Contents

the Agreement may adversely affect our operation in terms of the execution of inter-carrier mutual settlements among CIS-operators. In order to be implemented, the corresponding provisions should be introduced to the Russian legislation. To date, the provisions have not been implemented yet.

        In December 2013 and July 2014, the State Commission for Radio frequencies introduced a number of modifications to the conditions of using the frequency band for 3G and 4G. These changes resulted in implementation of the principle of technological neutrality for frequency bands 900 MHz (UMTS and LTE) and 1800 MHz (LTE). The Government Regulation No. 480 dated May 24, 2014, requiring that tenders shall be held mainly in the form of auctions, came into force on June 6, 2014.

        These changes may strengthen competition in the market as well as add costs for development of the network infrastructure.

        According to press reports, a proposal on carrying international traffic from the country's territory through the networks of nationwide operators is being considered. The list of nationwide operators has not been specified yet. In case such initiative is implemented and MTS is not included in the list of nationwide operators, this may lead to an increase in our traffic transmission costs.

        According to Government Regulation No. 1240 dated November 24, 2014, starting from January 1, 2015, federal public bodies were vested with a right to make decisions on using data transmission network of government bodies, which is a part of infrastructure ensuring information and technological interaction with the information systems used for rendering state and municipal electronic services for the purposes of exercising public functions. To date, the single operator of infrastructure of electronic state services is Rostelecom. Adoption of the Regulation may adversely affect our revenues with regard to the B2G market segment due to competitive disadvantage.

        With the entry into force of the Treaty on the Eurasian Economic Union (the "EEU") on January 1, 2015, a supra-national antimonopoly body empowered to control compliance with general competition rules on cross-border markets and to apply antitrust measures was established. Should violations with respect to companies operating on cross-border markets be identified, this might lead both, to imposition of fines in accordance with the legislation of the EEU and adoption of the decisions for compulsory execution.

        The amendments introduced to Article 5 of the Federal Law No. 115 "On Combating Legalization (Laundering) of Criminally Gained Income and Financing of Terrorism" dated August 7, 2001, entered into force on March 1, 2015. The list of organizations carrying out cash/other property operations, to whom the law requirements are applied, was expanded according to those amendments. In addition to telecommunications operators entitled to independently render mobile radio telecommunications services, the telecommunications operators occupying "substantial position" in public switched telephone networks entitled to independently provide data transmission services and render services on the basis of contracts with individual subscribers, have been also included in the list. A telecommunications operator which meets the specified criteria is obliged to provide the Federal Financial Monitoring Service with the information on cash/other property operations (that is subject to compulsory control or that seems suspicious while implementing the rules of internal control), as well as to take measures for freezing of cash assets / other property (in case there is an information on its involvement in extremist activities or terrorism). Lack of law enforcement practice may cause difficulties in interpreting the above-mentioned amendments and lead to additional burden for telecommunications operators.

        On July 8, 2017, the Federal Law No. 110 "On amendments to Article 66 of the Federal Law "On Communications" and Article 35 of the Federal Law "On Mass Media" dated June 7, 2017 came into force, which requires operators to transmit warning signals to telecommunications services users or inform them about dangers arisen by threat of occurrence of emergencies or occurrence of

emergencies. Expenditure related to the transmission of warning signals is not compensated to operators.

        On April 4, 2016, the Ministry of Communications of the Russian Federation adopted the order No. 135 "On the approval of requirements for communication networks operation with respect to the use of services provided by third parties." The order came into force on July 26, 2017.

        According to the requirements, a telecommunications operator is obliged (on a quarterly basis) to provide authorities with data on foreign companies and foreign citizens that are engaged to provide works or services related to exploitation and management of its communication network. In addition, a telecommunications operator is obliged to store information concerning all actions on communication facilities executed by servicing staff or third parties engaged in exploitation and management of communication networks both from workplaces and with the use of a remote access.

        Consultations are underway with the Ministry of Communications of the Russian Federation to determine the exact list of communication facilities and actions, information in respect of which has to be stored. The amount of forthcoming costs is to be determined based on the consultations' results and first results of complying with requirements.

        The Federal Law No. 374 "On the introduction of amendments to certain legislative acts of the Russian Federation with respect to setting up of additional counter-terrorism measures and public security enforcement" was adopted on July 6, 2016. Pursuant to that law, operators are obliged to store information on the facts of receiving, transferring, delivery and/or processing of voice information and text messages, as well as images, sounds, video- and other messages of telecommunications services users (for a three-year period) and the contents of such communications, including voice data, text messages, pictures, sounds, video or other communications (for up to six months). The requirement relating to the storage of messages contents enters into force on July 1, 2018. The Government of the Russian Federation is responsible for approving the rules, terms and volume of information to be stored. The Government regulation "On rules, terms and volume of voice information, text messages, images, sounds, video- and other messages of telecommunications services users to be stored" was adopted on April 19, 2018. According to this regulation, voice traffic is required to be stored for a period of six months starting from July 1, 2018, and data traffic is required to be stored, starting from October 1, 2018, by using data storage technical equipment in the volume of electronic communication messages sent and received by the operator's subscribers (the actual traffic) during 30 days before the commissioning date of the technical equipment. Moreover, the capacity of the data traffic storage system is required to be increased by 15% annually. Significant additional costs will be required in order to comply with these requirements.

        Currently, the Russian Civil Code is undergoing the process of substantial revisions with new provisions being introduced relating to a number of sectors. At present, the potential interpretation of these amendments by state authorities (including the courts), along with their impact on our activities are unknown.

        On July 29, 2017, Federal Law No. 245 "On Amendments to the Federal Law" On Communications" was adopted and is aimed at further aligning the process of concluding a contract for the provision of mobile radiotelephone communication services without appropriate identification of a subscriber (i.e., a user) of communication services. The effective date for these changes is June 1, 2018. Additional costs will be required to provide a set of measures to improve the filling of databases with information about subscribers and the organization of interaction with state systems to verify the reliability of information about subscribers.

        Russian companies are obliged to pay various and significant taxes including income tax, VAT, real estate tax, excise tax, payroll tax and others. Along with tax liabilities there are different obligatory non-tax payments. These include payments into Universal Service Fund, which currently amounts to

55

Table of Contents

1.2% of our annual revenue on telecommunications services. Furthermore, potential regulatory changes that may be enacted in the future, such as the introduction of new rules regulating MVNOs, new rules concerning our pricing policy and others, could weaken our competitive position in the mobile telecommunications market. Changes in tax laws and non-tax regulations may lead to the growth of our tax burden and may, as a result, materially adversely affect our financial condition and results of operations.

The failure of our subsidiaries that are subject to regulations as natural monopolies to comply with the requirements of the Federal Law No. 223 "On Procurement Process," inter alia, in case of collective tendering can lead to penalties on our subsidiaries.

        One of our subsidiaries, MGTS, is categorized as a natural monopoly in the Moscow telecommunications market. According to the Federal Law No. 223 "On Procurement Process," natural monopolies are obliged to conduct the procurement process in accordance with the principles of transparency and non-discrimination and unjustified limitation of competition. If our subsidiaries that are under additional regulations as natural monopolies are found failing to comply with the law on procurement process, inter alia in case of collective tendering with us, our subsidiaries can be subject to penalties. See also "—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate and are determined to have abused this position, the FAS may be entitled to regulate our subscriber tariffs and impose certain restrictions on our operations."

Russian and foreign legislation on personal data and information security in information systems and communication networks may turn out to be hard to implement and require significant resources. Inability to comply with the requirements may lead to sanctions.

        Communication operator activity in the sphere of information security in the Russian Federation is represented by the following legal acts: Federal laws "On communication," "On information, information technologies and information protection," "On personal data," "On trade secret," "On electronic signature," by-laws of the Government, FSTEC, FSS, Ministry of Communication and The Federal Service for Supervision of Communications, Information Technology and Mass Media of the Russian Federation, among others. Main risks, posed by organization of processing and providing security of personal data include the following factors:

•

ambiguity of applicability of legislation on communication, personal data, trade secret, etc. to a single object of legal regulation. Data may be simultaneously attributed to different categories of limited access information, which fall under different information security requirements under different sections of the Russian legislation;



•

responsibility of personal data operators for the actions of the third parties, processing personal data at the request of personal data operators;



•

ambiguity of the criteria for determining personal data protection level during its processing in the information systems (for example, in case undocumented possibilities in system and/or applied software exist), set by Government Decree No.1119, dated November 1, 2012;



•

high level of requirements to the personal data protection;



•

significant costs on creation of information protection system and support of protection level;



•

necessity to use the means of information protection, which have undergone a special conformity assessment procedure; replacement of the existing means of information protection with the ones, certified by FSTEC and FSS of Russia may require additional costs on certification of the existing means of information protection and later on certificates renewal (because of the limited period of certificates validity);

Table of Contents

•

in case of untimely obtaining licenses or untimely confirmation of licenses for the technical and cryptographic protection activity of confidential information by FSTEC of Russia or FSS of Russia, the company wouldn't be able to provide the corresponding commercial services to the third parties; and



•

ambiguity of the requirement of Federal law No. 152 to localize processing of the Russian citizens personal data on the territory of Russia, keeping the possibility of cross-border transfer of this data.

        In case of non-compliance with the Russian legislation on information security and personal data protection, the company cannot rule out the possibility of imposing sanctions by the regulatory bodies in the form of fines, confiscation of uncertified means of information protection, suspension of business processes for 90 days as well as suspension or withdrawal of the license, allowing to provide communication services, technical and cryptographic protection of confidential information.

        In addition, it is possible that subscribers will file legal claims, seeking to reimburse tangible and moral damage in connection with the violation of the legislation requirements. With effect from May 25, 2018, the General Data Protection Regulation will come into force in the European Union. At the moment, it is unclear how the requirements of this new Regulation may affect operations of companies that are subject to them. If the resources required to maintain, develop and implement data protection and information security systems meeting the legislation requirement are greater than expected, or we fail to comply with the data protection and information security laws despite our best efforts to do so, our business, financial condition and results of operations could be materially adversely affected.

Changes in Ukrainian telecommunications legislation have caused uncertainty in relation to the regulation of the Ukrainian telecommunications industry and may adversely affect our business, financial condition and results of operations.

        In November 2012, the NCCIR issued the decision regarding the rules governing the provision of MNP service, which enables the subscribers to retain their telephone number after switching from one operator of mobile communications to another. MNP law came into legal force on July 5, 2013 with the beginning of switching to other operators from December 20, 2013. On December 30, 2013 a resolution that postponed the beginning of service provision to July 2014 came into legal force, however, implementation of MNP service was cancelled later on by a court decision. On July 31, 2015, the NCCIR approved the procedure for MNP service rendering and introduced amendments to the basic requirements of agreements for the provision of telecommunications services. The decision entered into force on September 8, 2015, after which the NCCIR appointed the Ukrainian State Center of Radio Frequencies ("USCRF") as an administrator of the centralized database of the ported numbers.

        In May 2017, operators received approved documents including technical requirements for MNP service. As of March 2018, the court proceedings regarding the choice of a supplier for the centralized database were still ongoing. The terms of MNP service launch must be set by the special decision of the NCCIR which has not been passed yet.

        The Verkhovna Rada of Ukraine regularly reviews different versions of draft laws "On Electronic Communications." The key one of these draft laws requires, inter alia, the identification of the entire subscriber base of operators. The draft law provides for a period of compulsory registration, being six months. The inability to identify subscribers within the prescribed timeframe could have a negative effect on business operations of VF Ukraine. The request of VF Ukraine and PrJSC "Kyivstar" with regard to extending the transition period to two years was passed to legislators by way of an official letter.

Table of Contents

        In addition, on July 28, 2017, the NCCIR submitted for consideration to the Ukrainian government a new procedure for the identification of anonymous subscribers, which obliges operators to register subscribers in electronic form. The approval of this procedure and the introduction of an electronic subscriber identification system may result in additional costs for new equipment, interface, software and tools for digital signature recognition.

        Legislative changes regulating the telecommunications industry may materially adversely affect our business, financial condition and results of operations. See "Item 4—Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in Ukraine—Legislation."

The Russian taxation system is underdeveloped and any imposition of significant additional tax liabilities could have a material adverse effect on our business, financial condition or results of operations.

        The discussion below provides general information regarding the Russian tax regime and is not intended to be inclusive of all issues. Investors should seek advice from their own tax advisors as to these tax matters before investing in our shares and ADSs. See also "Item 10—Additional Information—E. Taxation."

        In general, taxes payable by Russian companies are substantial and numerous. These taxes include, among others, corporate income tax, value added tax, property taxes, excise duties, payroll-related taxes and other taxes.

        As of January 1, 2012, changes to the Tax Code of the Russian Federation enable Russian taxpayers that are part of a group to consolidate their financial results for profit tax purposes. It is yet unclear how the new legislative provisions will be applied by the tax authorities as currently only limited regulatory guidance is available on this matter. In addition to imposing certain criteria that must be met in order to create a consolidated tax-paying group, the law also limits certain transactions within the group (e.g. corporate restructurings). In 2014, we concluded an agreement with tax authorities, according to which the consolidated taxpaying group had to start functioning since 2016.

        However, pursuant to the law adopted in November 2015, the contracts on the set up of the consolidated taxpaying group were not subject to registration during the period of 2016 to 2017, and the contracts registered during the period of 2014 to 2015 are considered by tax authorities as not having been registered. In the absence of any official interpretation, it is currently difficult to estimate the implementation of new law on the agreements already registered by tax authorities.

        In addition, intercompany dividends are subject to a withholding tax of 0% or 13% (depending on whether the recipient of dividends qualifies for Russian participation exemption rules), if being distributed to Russian companies, and 15% (or lower, subject to benefits provided by relevant double tax treaties), if being distributed to foreign companies.

        The Russian tax authorities may take a more assertive position in their interpretation of the legislation and assessments, and it is possible that transactions and activities that have not been challenged in the past may nonetheless be subject to challenges in the future. The foregoing factors raise the risk of the imposition of arbitrary or onerous taxes on us, which could adversely affect the value of our shares and ADSs.

        Current Russian tax legislation is, in general, based upon the formal manner in which transactions are documented, looking to form rather than substance. However, the Russian tax authorities are increasingly taking a "substance and form" approach, which may cause additional tax exposures to arise in the future. Moreover, the Russian Tax Code was amended with direct provisions which prohibit tax benefits, if achieved without real business activities, or the main aim of the transaction was tax benefits. Additional tax exposures could have a material adverse effect on our business, financial condition, results of operations and prospects.

        It is expected that Russian tax legislation will become more sophisticated, which may result in the introduction of additional revenue raising measures. Although it is unclear how any new measures would operate, any such introduction may affect our overall tax efficiency and may result in significant additional taxes becoming payable. Additional tax exposures could have a material adverse effect on our business, financial condition, results of operations and prospects.

        In addition to the usual tax burden imposed on Russian taxpayers, these conditions complicate tax planning and related business decisions. For example, tax laws are unclear with respect to deductibility of certain expenses. This uncertainty could possibly expose us to significant fines and penalties and to enforcement measures, despite our best efforts at compliance, and could result in a greater than expected tax burden.

        See also "Item 8—Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Tax Audits and Claims."

Lack of law enforcement practice of the Russian anti-offshore policy may have adverse impact on our business, financial condition and results of operations.

        In the past few years, the Russian Federation like a number of other countries in the world has been actively involved in a discussion of measures against tax evasion by the use of low tax jurisdictions as well as aggressive tax planning structures.

        The rules of controlled foreign companies (CFC) came into force on January 1, 2015. The rules oblige Russian taxpayers being controlling persons of a foreign company to submit to the tax authorities both standard notifications on participation in CFC and tax declarations in certain cases. Profit generated commencing in 2015, including retained earnings, is subject to taxation in the Russian Federation. The innovations could impose additional tax on the undistributed profits of any foreign entity controlled by us (in proportion to such controlling stake) at the rate of 20%. These innovations caused amendments to the Tax Code providing for liability in case of non-disclosure or incomplete disclosure of information on CFCs and the non-payment or underpayment of relevant tax.

        In addition, implementation of new concept of beneficial ownership, with regard to taxation of payment of passive income (dividends, royalty, interest, capital gain), may negatively affect possibility to apply benefits set by the double tax treaties, in case such payments pass through intermediary entities.

        This may potentially lead to increase of tax burden with regard to such payments.

        On November 4, 2014, the President of the Russian Federation signed the Federal law No. 325 "On ratification of the Convention on Mutual Administrative Assistance in Tax Matters." Ratification of this Convention will enable the Russian Federation to receive tax information from all participating countries, which include a number of offshore jurisdictions.

        Lack of law enforcement practice may cause difficulties in interpreting the above-mentioned laws by the Russian tax authorities. It is also currently unclear how the enacted laws could affect our counterparties, which may be registered in off shore jurisdictions.

        In case the impact of legislative initiatives is significant for some of our counterparties it may also impact our results of operations.

The tax system in Ukraine is undergoing a reform and various tax laws are subject to different interpretations.

        Taxes and statutory charges are levied in accordance with the Tax Code of Ukraine ("TCU") that came into effect in 2011. Along with TCU requirements, Ukrainian taxpayers are obligated to follow other legal acts and legislative provisions. Applicable taxes include value added tax ("VAT"), corporate income tax ("CIT"), customs duties, payroll taxes and other taxes. Ukrainian legislation is ambiguous,

which could result in various tax disputes due to a number of mutually controversial or incomplete provisions.

        For example, payments for computer software can be treated as royalty or payments for intangible assets depending on whether a company purchases end-user rights or not. VF Ukraine purchases limited rights for the use of computer software, which are currently determined as end-user rights with an appropriate taxation. However, such treatment could still be disputed.

        Also, rules established by the TCU for recalculation of the input tax credit for non-current assets are unclear. Uncertain transfer pricing rules and their inconsistent application by the Ukrainian tax authorities and courts may also adversely affect VF Ukraine's operations. VF Ukraine's transactions with its non-resident related parties as well as certain transactions with other non-residents registered in low-tax jurisdictions (exhaustive list of these jurisdictions is established by the Cabinet of Ministers of Ukraine) may fall under transfer pricing ("TP") rules. For 2017 such transactions should be treated as controlled ones provided the following two conditions are met: (i) taxpayer's annual income exceeds UAH 150 mln; (ii) total volume of transactions with one counterparty for the respective year exceeds UAH 10 mln. Based on TP legislation, Ukrainian entities engaged in controlled transactions are required to submit report on controlled transactions and prepare transfer pricing documentation to substantiate the price in a particular controlled transaction. However, we may not exclude the risk that the tax authorities might challenge the prices in intercompany transactions taking into consideration the fact, that TP practice in Ukraine is relatively new and there is lack of practical cases describing approach applied by tax authorities regarding intra-group pricing. In case of any price adjustments, VF Ukraine's effective tax rate may increase and its financial results may be adversely affected.

        Starting from 2018, to determine whether or not the taxpayer's business transactions are to be treated as controlled, the volume of such transactions should be calculated based on arm's length prices (instead of contractual prices as was previously commonly used in practice). These changes are intended to eliminate possible abuses such as a deliberate understatement of contractual prices; however, they may give rise to disputes with the tax authorities concerning the determination of whether the transactions should be treated as controlled.

        Generally, tax returns as well as primary documents in Ukraine can be subject to inspection for a three-year period and, for issues of transfer pricing—for a seven-year period. However, this term may be extended under certain circumstances, including criminal investigation.

        By the end of 2017, VF Ukraine had one unsettled dispute regarding advance CIT-payments:

•

the possibility to credit subsidiaries' CIT-overpayments generated at separate accounts against Company's CIT payable.

        In 2017, VF Ukraine submitted adjustments to CIT-returns for the years ended December 31, 2015 and 2016 in order to eliminate double taxation, arising from different profit calculation for accounting and tax purposes in earlier periods.

        During 2017 there was an obligation to register VAT invoices within 15 days from the date of issuance the act of acceptance or from the date of prepayment. In case VAT invoice is not registered, tax authorities may impose penalties up to 100%.

        CIT regulation may undergo significant changes in the nearest future. Ukraine is considered to move from tax regime under which companies' taxable profits are subject to a system where tax is paid only if corporate profits are distributed. Ukrainian companies are expected to be taxed on their actual and deemed distributed profits, including expenses incurred or other payments unrelated to economic activities, etc. It is not stated yet if the companies will be able to use deferred tax assets or set off CIT-overpayments against future tax payable. These and other changes could have a material adverse effect on our results of operations and financial condition.

        While we believe that we currently comply with the tax laws affecting our operations in Ukraine, it is possible that relevant authorities may take differing positions with regard to interpretative issues resulting in additional payment obligations and penalties, which may result in a material adverse effect on our results of operations and financial condition.

Vaguely drafted Russian transfer pricing rules, and lack of reliable pricing information may impact our business and results of operations.

        Russian transfer pricing legislation became effective in the Russian Federation on January 1, 1999.

        This legislation allowed the tax authorities to make transfer pricing adjustments and impose additional tax liabilities with respect to all "controlled" transactions, provided that the transaction price differed from the market price by more than 20%. "Controlled" transactions included transactions with related parties, barter transactions, foreign trade transactions and transactions with significant price fluctuations (i.e., if the price with respect to such transactions differs from the prices on similar transactions conducted within a short period of time by more than 20%). Special transfer pricing provisions were established for operations with securities and derivatives. Russian transfer pricing rules were vaguely drafted, generally leaving wide scope for interpretation by Russian tax authorities and courts. There has been very little guidance (although some court practice is available) as to how these rules should be applied. These transfer pricing rules apply with respect to transactions that occurred before January 1, 2012.

        New transfer pricing rules became effective on January 1, 2012. The implementation of these new rules should help to align domestic rules with OECD principles. The new rules are expected to considerably toughen the previously effective law by, among other things, effectively shifting the burden of proving market prices from the tax authorities to the taxpayer and obliging the taxpayer to keep specific documentation.

        If the Russian tax authorities were to impose significant additional tax liabilities through the introduction of transfer pricing adjustments, they could have a material adverse impact on our business, financial condition and results of operations. The adoption of the new transfer pricing rules may increase the risk of transfer pricing adjustments being made by the tax authorities. In addition to the usual tax risks and tax burden imposed on Russian taxpayers, the uncertainties of the new transfer pricing rules complicate tax planning and related business decisions. It will also require us to ensure compliance with the new transfer pricing documentation requirements proposed in such rules. Uncertainty of the new rules may also require us to expend significant additional time and material resources for implementation of our internal compliance procedures. Tax authorities could impose additional tax liability as well as 40% penalties on the underpaid tax in case the prices or profitability are outside the market range and if the required transfer pricing documentation has not been prepared, which could have a material adverse effect on our results of operations and financial condition.

The regulatory environment for telecommunications in Russia, Ukraine and other countries where we operate or may operate in the future is uncertain and subject to political influence or manipulation, which may result in negative and arbitrary regulatory and other decisions against us on the basis of other than legal considerations and in preferential treatment for our competitors.

        We operate in an uncertain regulatory environment. The legal framework with respect to the provision of telecommunications services in Russia and Ukraine and the other countries where we operate or may operate in the future is not well developed, and a number of conflicting laws, decrees and regulations apply to the telecommunications sector.

        Moreover, regulation is conducted largely through the issuance of licenses and instructions, and governmental officials have a high degree of discretion. In this environment, political influence or manipulation could be used to affect regulatory, tax and other decisions against us on the basis of other

61

Table of Contents

than legal considerations. In addition, some of our competitors may receive preferential treatment from the government, potentially giving them a substantial advantage over us.

We are subject to currency control regulations.

        The Currency Control Law provides a framework and establishes general rules within which the government of Russia and the Bank of Russia are authorized to introduce certain measures of currency regulation, in connection with which there may be some uncertainty in the process of our implementation of foreign exchange operations when importing equipment.

        The change in the currency regulation may negatively affect our performance of obligations under contracts previously concluded with Russian and foreign counterparties, requiring us to make payments on them in foreign currency and necessitating the conclusion of additional agreements in relation to the relevant contracts. As a result, we are exposed to the risks of changes in the currency regulation and foreign exchange control in Russia.

The introduction of new critical information infrastructure regulation may lead to additional costs which could have a material adverse effect on our business, financial condition, results of operations and prospects.

        Federal Law No. 187 "On the Security of the Critical Information Infrastructure of the Russian Federation" which came into force on January 1, 2018 (the "Law on CII") provides for the creation of a register of CII objects, to which the communication networks are assigned. Both state-owned and non-state-owned organizations are classified as subjects of the CII.

        The law envisages criminal penalties imposed on officials owning CII objects if the security requirements in respect of such CII objects are not met and damage is incurred. Information on CII objects security is classified as a state secret. CII subjects, including communication operators, are required to, among other things:

•

categorize CII objects (for the communication operators they include at least communication network management system, attributing communication networks to the first (the highest) category is likely);



•

agree the allocation between categories with the authorities (FSTEC—Federal Service for Technology and Export Control of the Russian Federation);



•

introduce a dedicated position or assign a person, responsible for CII objects security management;



•

create a security system and implement measures targeted at CII protection and protection of information, belonging to the corresponding category; and



•

set up and provide the operations of means for attacks search on the communication network with the transfer of management to the authorized body (FSS of Russia).

        Draft by-laws envisage measures aimed at CII objects protection, which are difficult to implement, especially as regards the use of certified information protection means, which are not used in such communication standards as 3GPP, ETSI, etc. The implementation of these requirements will likely require additional costs to be incurred. Introduction of this or similar regulations, which may require additional costs to be incurred by us or otherwise negatively affect us could have a material adverse effect on our business, financial condition, results of operations and prospects.

Risks Relating to the Shares and ADSs and the Trading Market

Government regulations may limit the ability of investors to deposit shares into our ADS facility.

        The ability of investors to deposit shares into our ADS facility may be affected by current or future governmental regulations. For example, under Russian securities regulations, no more than 25% of a Russian company's shares may be circulated abroad through sponsored depositary receipt programs. Prior to December 31, 2005, and at the time of our initial public offering, this threshold was 40%. Although we believe that the new lower threshold does not apply to our ADSs, in the future, we may be required to reduce the size of our ADS program or amend the depositary agreement for the ADSs.

        Because our ADS program is regularly at or near capacity, purchasers of our shares may not be able to deposit these shares into our ADS facility, and ADS holders who withdraw the underlying shares from the facility may not be able to re-deposit their shares in the future. As a result, effective arbitrage between our ADSs and our shares may not always be possible. Our shares are listed and traded on the Moscow Exchange. Due to the limited public free float of our common stock, the public market for our shares is significantly less active and liquid than for our ADSs. The cumulative effect of these factors is that our shares may from time to time, and for extended periods of time, trade at a significant discount to our ADSs.

Failure to comply with requirements on the disclosure of certain information on ADSs and ADS holders may restrict your ability to vote.

        Pursuant to the Russian securities laws, depositaries, and as a result, ADS holders are not able to vote in connection with the shares underlying ADSs on behalf of the ADS holders unless they provide certain information to the issuer. At a minimum, this information includes the identity of the holder of the ADSs, registration details including a state registration number (for legal entities), and the number of shares attributable to each ADS holder.

        Nevertheless, the legislation stipulates that the issuer, CBR, Russian courts and pretrial investigation agencies may request such lists of depositary receipt holders from the holder of depositary program depo account. The holder of depositary program depo account shall take all reasonable measures in order to provide such information. In case of non-compliance with the above requirements, the CBR may suspend, or impose limitations on, transactions with securities held in the relevant accounts of Russian custodians for a period of up to six months. As a result, the shares underlying the ADSs may be blocked and it may be impossible to deposit or withdraw the shares into or from the depositary program. In addition, uncertainties with respect to exercise of certain rights attaching to shares underlying ADS holders could complicate the exercise of right to, and the ability to derive benefits from, the shares represented by ADSs.

The market price of our ADSs has been and may continue to be volatile.

        The market price of our ADSs experienced, and may continue to experience, significant volatility.

        For information on the closing price of our ADSs on the New York Stock Exchange, see "Item 9—Offer and Listing Details—A.4. Market Price Information."

        Numerous factors, including many over which we have no control, may have a significant impact on the market price of our ADSs, including, among other things:

•

periods of regional or global macroeconomic instability;



•

announcements of technological or competitive developments;



•

regulatory developments in our target markets affecting us, our customers or our competitors;

63

Table of Contents

•

actual or anticipated fluctuations in our quarterly operating results;



•

changes in financial estimates or other material comments by securities analysts relating to us, our competitors or our industry in general;



•

the value of local currencies in the markets where we operate compared to the US dollar;



•

announcements by other companies in our industry relating to their operations, strategic initiatives, financial condition or financial performance or to our industry in general;



•

announcements of acquisitions or consolidations involving industry competitors or industry suppliers;



•

sales or perceived sales of additional ordinary shares or ADSs by us or our significant shareholders; and



•

impact and development of any investigation or lawsuit, currently pending or threatened, or that may be instituted in the future.

        For example, market price of our ADSs experienced volatility in 2017 due to legal proceedings relating to Sistema, initiated by Rosneft, Bashneft and the Ministry of Land and Property Relations of Republic of Bashkortostan, and arrest of 31.76% of shares in our authorized capital held by Sistema, which was lifted in December 2017 as a result of execution of the settlement agreement.

        In addition, the stock market in recent years has experienced extreme price and trading volume fluctuations that often have been unrelated or disproportionate to the operating performance of individual companies. These broad market fluctuations may adversely affect the price of our ADSs, regardless of our operating performance.

Voting rights with respect to the shares represented by our ADSs are limited by the terms of the deposit agreement for our ADSs and relevant requirements of Russian law.

        ADS holders will have no direct voting rights with respect to the shares represented by the ADSs.

        They are able to exercise voting rights with respect to the shares represented by ADSs only in accordance with the provisions of the deposit agreement relating to the ADSs and relevant requirements of Russian law. Therefore, there are practical limitations upon the ability of ADS holders to exercise their voting rights due to the additional procedural steps involved in communicating with them. For example, the Joint Stock Companies Law and our charter require us to notify shareholders no less than 30 days prior to the date of any meeting and at least 50 days prior to the date of an extraordinary meeting to elect our Board of Directors. Our ordinary shareholders will receive notice directly from us and will be able to exercise their voting rights by either attending the meeting in person or voting by power of attorney.

        ADS holders by comparison, will not receive notice directly from us. Rather, in accordance with the deposit agreement, we will provide the notice to the depositary. The depositary has undertaken, in turn, as soon as practicable thereafter, to mail to ADS holders the notice of such meeting, voting instruction forms and a statement as to the manner in which instructions may be given by ADS holders.

        To exercise their voting rights, ADS holders must then instruct the depositary how to vote the shares represented by the ADSs they hold. Because of this additional procedural step involving the depositary, the process for exercising voting rights may take longer for ADS holders than for holders of the shares and we cannot assure ADS holders that they will receive voting materials in time to enable them to return voting instructions to the depositary in a timely manner. ADSs for which the depositary does not receive timely voting instructions will not be voted.

64

Table of Contents

        Given the above, we cannot provide any assurance that holders and beneficial owners of ADSs will (i) receive notice of shareholder meetings to enable the timely return of voting instructions to the depositary, (ii) receive notice to enable the timely cancellation of ADSs in respect of shareholder actions or (iii) be given the benefit of dissenting or minority shareholders' rights in respect of an event or action in which the holder or beneficial owner has voted against, abstained from voting or not given voting instructions.

        See also "—Failure to comply with requirements on the disclosure of certain information on ADSs and ADS holders may restrict your ability to vote."

ADS holders may be unable to repatriate distributions made on the shares and ADSs.

        We anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of ADSs, net of the depositary's fees and expenses. The ability to convert rubles into U.S. dollars is subject to the availability of U.S. dollars in Russia's currency markets.

        Although there is an existing, albeit limited by size, market within Russia for the conversion of rubles into U.S. dollars, including the interbank currency exchange and over-the-counter and currency futures markets, the further development of this market is uncertain. At present, there is a limited market for the conversion of rubles into foreign currencies outside of Russia and limited market in which to hedge ruble and ruble-denominated investments.

ADS holders may be subject to Russian regulatory restrictions.

        Prior to the amendments to the Russian securities laws introduced in 2011, a depositary bank could be considered the owner of the shares underlying the ADS, and as such could be subject to the mandatory public tender offer rules, anti-monopoly clearance rules, governmental consents or reporting requirements in respect of acquisition of shares and other limitations contemplated by Russian law. The amendments to the Russian securities laws introduced in 2011 provide that a depositary bank is not an owner of underlying shares, and as such, these requirements should apply to ADS holders.

ADS holders may be unable to benefit from the United States—Russia income tax treaty.

        Under Russian law, dividends paid to a non-resident holder of the shares generally will be subject to Russian withholding tax at a rate of 15%. The tax burden may be reduced to 5% or 10% under the United States—Russia income tax treaty for eligible U.S. holders; a 5% rate may potentially apply for U.S. holders who are legal entities owning 10% or more of the company's voting shares, and a 10% rate applies to dividends paid to eligible U.S. holders in other cases, including dividend payments to individuals and legal entities owning less than 10% of the company's voting shares. However, according to the recent amendments to the Russian Tax Code, U.S. holders will only be able to utilize the 5% reduced rate through tax reimbursement procedures, as the tax agent is required to use the baseline tax rate established by the code or the applicable tax treaty, whichever is appropriate. See also "Item 10—Additional Information—E. Taxation—United States—Russia Income Tax Treaty Procedures."

        The Russian tax rules in relation to ADS holders (that would affect U.S. holders) are characterized by significant uncertainties and limited interpretive guidance. Recent amendments to the tax rules have clarified the status of the ADS holders as beneficial owners of the income from the underlying shares by establishing that the custodian holding the depo account with the shares underlying the ADSs acting as the tax agent and determines amounts of the withholding tax based on the information about the ADS holders and their tax residency status as provided by the program depositary. However, the application of the baseline tax rate for ADS holders and any double tax treaty relief is available only if the tax treaty residence of the holder is provided to the custodian along with the other information prescribed by the Tax Code. In relation to ADS holders such information is to be provided by the ADS

65

Table of Contents

holders to the depositary, who relays it to the custodian, who acts as the tax agent and withholds the taxes when making transferring the dividends to the depositary. It is currently unclear how the depositary will collect the necessary information from ADS holders. Thus, while a U.S. holder may technically be entitled to benefit from the provisions of the United States—Russia income tax treaty, in practice such relief may be difficult or impossible to obtain. See also "Item 10—Additional Information—E. Taxation" for additional information.

Capital gain from the sale of shares and ADSs may be subject to Russian income tax.

        Income received by a foreign company from the sale, exchange or other disposal (assuming that such income is not related to a permanent establishment of a foreign company in Russia) of shares (participation interest) in an organization in which over 50% of the assets consist of immovable property located in Russia, as well as financial instruments derived from such shares, is treated as income derived from a source in the Russian Federation and is subject to withholding tax at a rate of 20%. However, gains arising from the disposition of the securities, which are traded on an organized stock exchange, are not treated as Russian-source income, and should not be subject to taxation in Russia.

        The amount of such income is typically determined as the sales price of shares (participation interest). However, if documentary support for the acquisition cost of the shares (participation interest) is available, the tax may instead be assessed on the basis of the difference between the sales price and the acquisition cost (including other related costs) if documentary evidence of such costs is submitted to the tax agent. The Russian Tax Code also establishes special rules for calculating the tax base for the purposes of transactions with securities. However, an exemption applies if immovable property located in Russia constitutes more than 50% of a company's assets and the securities are traded on a foreign stock exchange. The determination of whether more than 50% of our assets consist of immovable property located in Russia is inherently factual and is made on an on-going basis and the relevant Russian legislation and regulations in this respect are not entirely clear. Hence, there can be no assurance that immovable property owned by us and located in Russia does not currently and will not constitute more than 50% of our assets as at the date of the sale of ADSs by non-residents.

        Where the ADSs are sold by legal entities or organizations to persons other than a Russian company or a foreign company or an organization with a registered permanent establishment in Russia, even if the resulting capital gain is considered taxable in Russia, there is currently no mechanism under which the purchaser will be able to withhold the tax and remit it to the Russian budget.

        Under the United States / Russia income tax treaty, capital gains from the sale of shares and/or ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the treaty) were to consist of immovable property located in Russia.

        The taxation of income of non-resident individuals depends on whether this income is received from Russian or non-Russian sources. Russian tax law does not give a definition of how the "source of income" should be determined with respect to the sale of securities, other than that income from the sale of securities, which takes place "in Russia" should be considered as Russian source income. As there is no further definition of what should be considered to be a sale "in Russia," the Russian tax authorities have a certain amount of freedom to conclude what transactions take place in or outside Russia, including looking at the place of the transaction, the place of the issuer of the shares, the location of the registrar recording the transfer of legal title to the relevant securities or other similar criteria.

        Non-residents who are individuals are taxable on Russian-source income. Provided that gains arising from the disposition of the foregoing types of securities and derivatives outside of Russia by U.S. holders who are individuals not resident in Russia for tax purposes will not be considered Russian

66

Table of Contents

source income, then such income should not be taxable in Russia. However, gains arising from the disposition of the same securities and derivatives "in Russia" by U.S. holders who are individuals not resident in Russia for tax purposes may be subject to tax either at the source in Russia or based on an annual tax return, which they may be required to submit with the Russian tax authorities. See also "Item 10—Additional Information—E. Taxation."

The lack of a developed practice relating to share registration system in Russia and other countries where we operate may result in improper record ownership of our shares, including the shares underlying the ADSs, and other problems connected with the rights attributed to the relevant shares such as dividend payments.

        Ownership of Russian joint stock company shares (or, if the shares are held through a nominee or custodian, then the holding of such nominee or custodian) is determined by entries in a share register and is evidenced by extracts from that register. Currently, the central registration system in Russia is under development. Since October 1, 2014, share registers of all joint stock companies are maintained by licensed registrars. Regulations were issued regarding the licensing conditions for such registrars, as well as the procedures to be followed by both companies maintaining their own registers and licensed registrars when performing the functions of registrar; however, companies are no longer able to maintain the registers themselves. Nevertheless, in practice registrars tend to have relatively low levels of capitalization and insufficient insurance coverage.

        On December 7, 2011, amendments to the relevant legislation were adopted, substantially reforming the registration system by introducing the CSD. In the course of this reform of the share keeping system, numerous different depositaries with accounts in the registers of companies were replaced by a single central depositary, whose primary function is the custody of shares in all major companies. These changes became effective on January 1, 2012 and are still being implemented. On November 6, 2012, FSFM officially appointed the National Settlement Depositary as the central depositary. Since the central depositary opened its account in MTS' register in March 2013, all the other custodians are restricted from opening their accounts in the register. Currently the central depositary is the only custodian with an account in MTS' register and other custodians hold custodial accounts with the central depositary.

        In addition, certain amendments to the Civil Code of the Russian Federation entered into force on October 1, 2013 regarding the transfer and restitution of securities that are aimed at protection of rights of security holders and on September 1, 2014 regarding the regulation of legal entities and their corporate governance. However, a centralized share registration system is currently undergoing a reform in Russia, therefore transactions in respect of a company's shares could be improperly or inaccurately recorded, and share registration could be lost through fraud, negligence, official and unofficial governmental actions or oversight by registrars incapable of compensating shareholders for their misconduct. This creates risks of loss not normally associated with investments in other securities markets.

        The National Securities and Stock Market Commission of Ukraine, by its decision No. 391 "On procedure of payment of dividends by a joint stock company" dated April 12, 2016 stated that joint stock companies might carry out dividend payments either through the depository system of Ukraine or directly to shareholders. The specific method of the dividend payment is determined by a relevant decision of the general shareholders meeting with respect to the entire issue of securities of the joint stock company. The Regulation No. 591 of the National Bank of Ukraine "On amendments to Certain Legislative Acts of the National Bank of Ukraine" that entered into force on September 23, 2014 was prolonged by the corresponding regulations of the NBU (the latest regulation expired on June 8, 2016).

        The regulations set the restriction on a number of operations in foreign currency, including repatriation of dividends to the foreign investor.

        According to the NBU Board Resolutions No. 342, 386, 410 "On Resolving the Situation in the Money and Foreign Exchange Markets of Ukraine" adopted in 2016, key currency restrictions have been re-extended until introduction of new resolutions of the NBU. The dividends may be repatriated with certain limitations. The Resolution of the NBU dated November 22, 2016 continued gradual mitigation of temporary restrictions on the currency market, by expanding opportunities for the clients of resident banks to purchase foreign currency in the interbank market.

        On April 13, 2017, the NBU adopted a resolution that allows the repatriation of dividends not only for the period of 2014 to 2015, but also for 2016, and simplifies the mechanism of such payments, allowing the repatriation of dividends for the specified years in a total amount of up to 5 million U.S. dollars within one month. The NBU adopted a resolution, which changes the terms of the repatriation of dividends to foreign shareholders of Ukrainian companies with effect from November 15, 2017. Accordingly, the repatriation of dividends accrued until 2016 is permitted. The monthly limit on the repatriation of dividends for the period of up to 2013 is equivalent to 2 million U.S. dollars. In March 2018 the NBU adopted another resolution, which permits repatriation of dividends to foreign shareholders of Ukrainian companies accrued until 2017 in a total amount of up to 7 million U.S. dollars per month.

Foreign judgments may not be enforceable against us.

        Our presence outside the United States may limit your legal recourse against us. We are incorporated under the laws of the Russian Federation. Substantially all of our directors and executive officers named in this document reside outside the United States. All or a substantial portion of our assets and the assets of our officers and directors are located outside the United States. As a result, you may not be able to effect service of process within the United States on us or on our officers and directors. Similarly, you may not be able to obtain or enforce U.S. court judgments against us, our officers and directors, including actions based on the civil liability provisions of the U.S. securities laws.

        In addition, it may be difficult for you to enforce, in original actions brought in courts in jurisdictions outside the United States, liabilities predicated upon U.S. securities laws.

        There is no treaty between the United States and the Russian Federation providing for reciprocal recognition and enforcement of foreign court judgments in civil and commercial matters. These limitations may deprive you of effective legal recourse for claims related to your investment in our shares and ADSs. The deposit agreement provides for actions brought by any party thereto against us to be settled by arbitration in accordance with the Commercial Arbitration Rules of the American Arbitration Association, provided that any action under the U.S. federal securities laws or the rules or regulations promulgated thereunder may, but need not, be submitted to arbitration. The Russian Federation is a party to the United Nations (New York) Convention on the Recognition and Enforcement of Foreign Arbitral Awards, but it may be difficult to enforce arbitral awards in the Russian Federation due to a number of factors, including the inexperience of Russian courts in international commercial transactions, official and unofficial political resistance to enforcement of awards against Russian companies in favor of foreign investors and Russian courts' inability to enforce such orders and corruption.

information without independent verification. The official data published by Russian federal, regional and local governments may be substantially less complete or researched than those of more developed countries. Official statistics may also be produced on different bases than those used in Western countries. Any discussion of matters relating to Russia in this document must, therefore, be subject to uncertainty due to concerns about the completeness or reliability of available official and public information. In addition, the veracity of some official data released by the Russian government may be questionable.

Because no standard definition of an average monthly service revenue per user ("ARPU"), average monthly usage per user ("MOU") or churn exists in the telecommunications industry, comparisons between certain operating data of different companies may be difficult to draw.

        The methodology for calculating subscriber numbers, ARPU, MOU and churn varies substantially in the telecommunications industry, resulting in variances in reported numbers from that which would result from the use of a uniform methodology. Therefore, comparisons of certain operating data between different telecommunications companies may be difficult to draw.

Factors over which we have little or no control may affect our revenues.

        Our business activities depend on a number of factors which are outside of our control, including natural disasters, imposition of a state of emergency in the countries of our operations, strikes and global and regional economic conditions. Any of these factors could result in deterioration of our revenues, which could have a material adverse effect on our results of operations, financial condition, prospects and the price of our ADSs.

        We completed our initial public offering on July 6, 2000, and listed our shares of common stock, represented by ADSs on the New York Stock Exchange (the "NYSE") under the symbol "MBT." Each ADS represents two underlying shares of our common stock. Prior to May 3, 2010, each ADS represented five shares of our common stock.

        In September 2001, we won a tender held by the Telecommunications Ministry of the Belarus Republic to form a joint venture with a GSM 900/1800 license to operate in Belarus. On June 26, 2002, MTS Belarus received all of the governmental approvals and licenses required to commence operations in Belarus and it began operations on June 27, 2002. In 2003 through a number of purchases we acquired a 100% stake in MTS Ukraine (now Vodafone Ukraine) for RUB 11,872 million. Starting from 2007 until 2015, we operated under the MTS brand in Ukraine. In 2015, as part of our strategic partnership with Vodafone, we introduced Vodafone brand in Ukraine.

        We started operations in Uzbekistan, following the two step acquisition of 100% ownership interest in Uzdunrobita in 2004 and 2007. In July 2012, we suspended providing services in Uzbekistan per the order from the State Agency for Communications and Information ("SACI") of Uzbekistan on the temporary suspension of the operating license of Uzdunrobita for a period of 10 business days which was subsequently extended to three months. On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated liquidation procedures. As a result, we lost control over the subsidiary and deconsolidated Uzdunrobita. In July 2014 the disputes between us and Republic of Uzbekistan were resolved. The parties signed the Settlement Agreement and according to its terms all mutual claims were eliminated. Furthermore, a new mobile operator, UMS, was established by governmental authorities of Republic of Uzbekistan. On September 24, 2014, an ownership interest of 50.01% in UMS was transferred to us as an incentive for reentrance into the country by the State Unitary Enterprise "Center of radio communications, radio broadcasting and television," the second shareholder of an operator, on behalf of the Republic of Uzbekistan. We started operations in Uzbekistan in December 2014. On August 5, 2016, we sold our 50.01% stake in UMS to the State Unitary Enterprise "Center of radio communications, radio broadcasting and television."

        Please see "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of our subsidiaries in the countries in which we are present to maintain control over their operations and assets may adversely affect our business, financial condition and results of operations" regarding recent suspension of our services in Uzbekistan and "Item 8. Financial Information—A. Consolidated Statements and Other Financial Information—7. Litigation—Uzbekistan."

        In two separate purchases in June and November 2005, we acquired 100% of BCTI, the leading wireless operator in Turkmenistan, for $46.7 million (RUB 1,343 million) in cash. Since October 2006, we have operated under the MTS brand in Turkmenistan. On December 21, 2010, the Ministry of Communication of Turkmenistan suspended our primary operating license and we ceased providing mobile telecommunications services in Turkmenistan. In August 2012, we restarted our mobile communication operations in Turkmenistan via MTS-Turkmenistan and resumed providing services for subscribers who did not cancel their contracts. Since October 1, 2012, we resumed our operations in Turkmenistan entirely and started entering into contracts with new subscribers. On September 29, 2017, we stopped providing communication services in Turkmenistan due to the actions of the state-owned telecommunication company Turkmentelekom, which resulted in the disconnection of international and long-distance zonal communication services and internet access. See "Item 3. Key Information—D. Risk Factors—Legal Risks and Uncertainties—The inability of MTS-Turkmenistan to sustain its operations in Turkmenistan on commercially acceptable terms or at all may adversely affect our business, financial condition and results of operations."

        In September 2007, we acquired an 80% stake in International Cell Holding Ltd., a 100% indirect owner of K-Telecom, the leading wireless operator in Armenia, for €260.0 million (RUB 9,142 million), and entered into a call and put option agreement initially valid until 2012 (and later extended until

2018) for the remaining 20%. K-Telecom operates in the GSM-900/1800 standard, covering the entire territory of Armenia. It historically operated under the VivaCell brand, and was re-branded as VivaCell-MTS in September 2008.

        In October 2009, we acquired a 50.91% stake in Comstar, a leading fixed line operator in Russia, from Sistema, and subsequently increased our ownership interest to 61.97% (or 64.03% excluding treasury shares) in December 2009 and to 70.97% (or 73.33% excluding treasury shares) in September 2010 through a voluntary tender offer. On December 23, 2010, the extraordinary general meetings of shareholders of Comstar and MTS approved a merger, which was completed on April 1, 2011. As a result, Comstar ceased to exist as a separate legal entity and MTS became the legal successor of Comstar in respect of all its rights and obligations.

        Prior to April 1, 2011, Comstar operated in both the Moscow and other fixed line communications markets, offering voice telephony, broadband Internet and pay-TV, operator interconnect and other services to its subscribers. As of now we still continue to provide these services. One of Comstar subsidiaries was MGTS, Moscow's incumbent fixed line operator with "last mile" access (the final phase of delivering connectivity from a communications provider to a customer) to approximately 96% of the households in Moscow. In 2011, we completed the re-branding of Comstar with our main MTS brand. MGTS continues to provide services under its own brand.

        In 2009, we started to develop our sales and distribution network both organically and through the acquisition of several national and regional retail chains. We organized our retail operations under a wholly owned subsidiary, Russian Telephone Company ("RTC"). RTC handles all functions relating to our retail operations, including the management of points-of-sale, the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets.

        Between 2009 and 2014 we acquired controlling stakes in various regional fixed line operators as we are determined to develop broadband Internet through regional expansion.

        In April 2013, we acquired a 25.095% stake in MTS Bank for 5.09 billion rubles through an additional share issuance by the bank. As of December 31, 2017 our interest comprised 26.61% of the bank's shareholding.

        In December 2014, we acquired controlling stakes in Penza-GSM, SMARTS- Ivanovo and SMARTS-Ufa, operating in Penza, Ivanovo and the Bashkortostan Republic, respectively. The acquired companies hold rights to use 900 and 1800 MHz radio frequencies within the regions mentioned. The acquisition enhances our spectrum resources in the above mentioned regions. The purchase price comprised of cash consideration and a deferred payment, payable in 18 months after the acquisition date. These companies were subsequently merged with MTS.

        In April 2014, we acquired a 10.82% stake in OZON , a leading Russian e-commerce company, through the purchase of OZON Holdings Limited's additional share issuance for RUB 2,702 million. Cooperation with OZON creates new distribution channels available to us through its extensive online retail platforms. As of December 31, 2017 our interest comprised 11.19%.

        In December 2015, we have completed the acquisition of NVision Group and its subsidiaries for RUB 11.2 billion. Through this transaction, we have obtained proprietary rights over our billing systems which will allow us to reduce the time-to-market for new products and better manage billing and IT-related expenses. NVision Group is also one of the largest system integrators and complex IT solutions providers in Russia.

        In September 2016, we acquired controlling stake in Smarts-Yoshkar-Ola, a company, operating in the Republic of Mari El and holding rights to use 1800 MHz radio frequencies. The acquisition enhances our spectrum resources in the Republic of Mari El.

        In October 2017, we acquired 50.82% of ownership interest in the Russian retail software developer Oblachny Retail LLC, operating under trademark LiteBox, with a call and put option arrangement existing over another 49.18% of shares. The deal allows us to enter the cloud-based cash register market as a fully licensed fiscal data operator ("FDO") and a provider of integrated digital cash management solutions for B2B clients.

        In December 2017, we purchased a 100% ownership interest in Praliss Enterprises, thus acquiring one of the world's leading eSport clubs—Gambit Esports. The acquisition is a part of our digital innovation strategy.

        In January 2018, we acquired a 78.2% of ownership interest in Kulturnaya Sluzhba LLC, operating under the trademark Ponominalu.ru. In February 2018, we acquired a 100% ownership interest in Moskovskaia Direktciia Teatralno-Kontcertnyh i Sportivno-Zrelishchnyh Kass LLC, operating under the trademark Ticketland.ru. These acquisitions allow us to enter the event ticket market, while broadening our suite of digital services, and integrate a key new product into existing loyalty program and mobile applications ecosystem.

Business Strategy

        Our key strategic goal is leadership in all markets of presence, delivering the best-in-the-market experience to our subscribers, including high-speed Internet access at home and on the go, cable and satellite TV entertainment with access to best content portfolio and top quality mobile and fixed voice services. We do our best to be at the forefront of LTE development in Russia and CIS and we are focused on building the fastest and most reliable 4G wireless networks and providing the best service to our customers by bringing access to the connected world.

        In order to achieve our goals to become a market leader in telecommunications we developed the new strategy in 2016, which is focused on digitalization is the progress of our "3D" strategy and evolved from "Data—Differentiation—Dividends" into "Data—Digital—Dividends." The decision to prioritise digitalization as our key areas of focus is driven by worldwide movement towards the digital era. Digitalization creates new demands for market players, stimulates them to search for new approaches to interaction with clients, radically changes the ways companies act, their management methods and corporate culture.In this regard, we see perspectives, new points of efforts which we can focus on to turn them into the points of growth and profitability.

and corporations, such as building high-speed 4G LTE networks which allows us to meet growing needs for data consumption. We ensure customers have the best possible connectivity experience at their homes, workplaces and places in between.

•

"Digital" is the main point where we plan to evolve in the nearest future. The basis for it was laid earlier by implementing "Differentiation" (the predecessor of "Digital" in our strategy), when we expanded our activity into such areas as retail, financial services, machine-to-machine, Big Data (large and complex data sets), E-Commerce and others. Implementation of the new digital strategy, will allow us not only to improve the arreas where we operate, but also to focus on dealing with and making revenue out of: information, knowledge, applications, content, loyalty management. At the same time going digital for us includes also the evolution of our corporate management and corporate culture to make them more proactive, flexible, ambitious, audacious and development-oriented.



•

"Dividends" is the result of our activities, of our efforts to make our operations effective both revenue- and profitability-wise. We continuously improve the operational efficiency of MTS, develop the organizational capabilities of our company, constantly work on organizational effectiveness and keep it responsive to market challenges and customer needs. We sustain high levels of business profitability and aim to enhance shareholder returns. We beleive that the processes of digitalization will open a number of opportunities for further major efficiency improvements.

        We strongly believe that the evolution of our strategy and our approach to further development will enable us to stay at the forefront of the telecommunication industry in all markets of our presence, to provide our customers with best user experience, to be a valuable and credible business-partner, trustworthy and effective investment for our shareholders.

        Implementation of the strategy is subject to a number of risks. See "Item 3. Key Information—D. Risk Factors" for a description of these and other risks we face.

As of December 31, 2017, we provided GSM, GPRS and EDGE services with more than 40,000 2G sites over the geographic area with more than 94.7% of population of Russia.

3G Technology

        In April 2007, we received a nationwide 3G/UMTS (Universal Mobile Telecommunications System) license in Russia. The license was valid till May 21, 2017 and covers the entire territory of Russia with frequencies 1950-1965 MHz and 2140-2155 MHz. In February 2017 the 3G/UMTS license in Russia were prolonged by the Federal Service for Supervision of Communications, Information Technoligy and Mass Media till May 21, 2022. We currently have commercial 3G networks launched in all regions of Russia with the exception of Crimea. By the end of 2017, we installed 41,621 3G sites throughout Russia.

        Starting from 2010, we implement HSPA+ technology, which supports up to 21 Mbit per second data transmission speed. In addition, we launched second and third 3G carriers to improve capacity and activated Dual Carrier technology, which supports up to 42 Mbit per second data transmission speed in more than 38,600 sites in Russia.

        Since 2011 we use 3G femtocell network. Femtocells are small low-power wireless base stations in the licensed 2100 MHz spectrum. They connect to a mobile operator's network using residential DSL or cable broadband connections and can support multiple standard mobile devices. Femtocells deliver a strong signal and high-quality voice service to standard mobile devices in homes, small and large offices, outdoor public spaces, metro hotspots and rural areas. A femtocell network also provides for high speed of data upload and download. In 2016 we launched offer of femtocells for consumers as B2C market segment. The total number of femtocells installed in Russia reached 9,094 by the end of 2017.

        In February 2015, we obtained UMTS spectrum in 2100 MHz band in Ukraine through an open tender held by the National Commission for the State Regulation of Communications and Informatization. Upon completion of critical network upgrades, we started providing our own 3G services in major Ukrainian cities under the Vodafone brand starting from November 2015. HSPA+ (QAM64 and Dual Carrier) technology, which is available in our 3G network from the start, allows to download speeds up to 42 Mbit\s.

        By the end of 2017 we rolled out 7300 UMTS-2100 base stations, offering 3G services in all Ukrainian sities with a population over 5 thousand people, which covered 80% of the total country population. For 2018 our plans include introduction of 4G (LTE) services in major Ukrainian cities, with regional centers in 1800MHz and 2600Mhz frequency spectrums.

        In October 2007, MTS Armenia, our subsidiary in Armenia was allocated frequencies to offer 3G services throughout the entire territory of Armenia. The frequencies were allocated for a 10-year period. In 2009, we commercially launched our 3G network in Armenia. In 2011, MTS Armenia started

to provide telecommunications services based on HSPA+ technology in Yerevan, six northern regions and in some southern regions of the country. At present HSPA+ technology with QAM64 and Dual Carrier features is available to almost 99% of the Armenian population. In 2016 we launched 90 new 3G base stations. In 2017 we continued development of RAN to increase network capacity. Optimal utilization of existing base stations and migration of subscribers' base from 2G/3G to LTE to utilize the existing capacity were ongoing processes. We also continued improving indoor coverage and capacity upgrades in hot spots by implementing indoor solutions. In 2018 we are planning to continue expansion of existing 3G and LTE networks for sustaining leadership in data provision.

LTE Technology

        In July 2012, the Russian Ministry of Communications and Mass Media announced the results of a tender for national-wide LTE-FDD frequencies. MTS is among the four companies, including Rostelecom, MegaFon, and VEON Ltd. (VimpelCom) which obtained LTE-FDD frequencies in 700, 800 and 2600 MHz bands.

        In September 2012, we began offering LTE-based commercial services in Moscow region.

        In 2014, we started DCS 1800 spectrum refarming to LTE and rolled out LTE-1800 network, while expanding LTE 800/2600 coverage. In February 2016 MTS won Russian Ministry of Communications and Mass Media tender for nationwide LTE-TDD license and obtained LTE-TDD frequencies in following band: 2595 - 2620 MHz for the whole territory of Russia, except Moscow region (obtained earlier). We plan to use LTE-TDD as a capacity layer to cope with increase of network utilization due to growth of data traffic. As of December 31, 2017, we had 41,648 LTE sites in 83 regions of Russia. In 2018, we are going to further roll out LTE in available frequency bands, implementing LTE-Advanced technologies.

        In 2017 we also continued upgrading our network infrastructure preparing for the upcoming LTE frequencies auctions (2600 MHz and 1800 MHz) and subsequent massive LTE rollout in 2018. As we expect significant surge of data usage, our main efforts were aimed at replacement of obsolete 2G base station with brand new multi-technology feeder-less solutions, transmission network capacity upgrades and packet core network modernization.

        In 2017 we upgraded IP\MPLS backbone with 200 Gbps links connecting major Ukrainian cities, put into operation more than 500 km of fiber optic lines, and continued capacity upgrades on our Microwave network.

        Along with LTE launches our plans for 2018 in Ukraine include: virtualized Evolved Packet Core and Value Added Services implementation, software-defined networking and new transmission network upgrades, full transition to unified network operations center, new efficiency improvement and energy saving initiatives.

Other Services

        In addition to cellular communication services, we offer corporate clients a number of telecommunications services such as design, construction and installation of local voice and data networks capable of interconnecting with fixed line operators, installation and maintenance of cellular payphones, lease of digital communication channels, access to open computer databases and data networks, including the Internet, and provision of fixed, local and long- distance telecommunications services, as well as video conferencing.

Strategic Partnership with Vodafone

        In October 2008, we announced a strategic agreement with Vodafone aimed at drawing on Vodafone's expertise in building and developing 3G networks and mobile broadband products, working

with leading global equipment providers and deploying innovative client relationship management ("CRM") practices to enhance quality and further improve the efficiency of our operations. In addition, the agreement allows us exclusive access to a range of products, services and devices from Vodafone for our markets of operation in Russia, Ukraine and Armenia.

        In 2015, the Group extended its strategic partnership agreement with Vodafone to introduce the Vodafone brand in Ukraine. In 2017 under the partnership, MTS Ukraine (now Vodafone Ukraine) and Vodafone continued to roll out 3G networks and to develop a number of new services, which have proved extremely popular in Europe, including bundled offers, competitive long-distance international calls and worry-free roaming when abroad, in the Ukrainian market. Other areas of cooperation remain in full force.

Sales and Marketing

Table of Contents

sport events, music shows and other popular events. We also coordinate the advertising policies of our dealers and partners, such as MTS Bank, to capitalize on the increased volume of joint advertising and preserve the integrity and high-quality image of the MTS brand.

        In line with our strategy to find new ways of effective communications, especially in the digital channel, we launched special activations with partner web-sites and several collaborations with popular Russian bloggers and other format of online advertising (online games, tests, advertorials, product placements etc) in 2017.

        To support our key directions we undertook the following initiatives in 2017 in Russia and in selected other countries in which we operate:

Brand and New Positioning

        In 2017, we continued our positioning with the tagline "You Know That You Can" as well as our visual style, which symbolizes going beyond limits, boldness and authenticity through the use of dynamic craft-style visuals. However, we elaborated MTS positioning by adding new business goals, which have led to development of the three communication focuses: network quality, client service and leadership. In order to convey the leadership, MTS used celebrities and public figures who achieved success and keep developing and opening new horizons.

Network Quality (40' coverage)

        Network quality has always been one of our key priorities and an important attribute influencing net-promoter score of the company. We constantly strive to improve the quality of our network, we continue to develop the infrastructure and implement new technologies. To maintain and improve the perception of our network quality:

•

We continued communications support for our 4G LTE mobile internet and launched large digital campaign emphasizing that our high-speed mobile internet ensures the speed of customer's applications.



•

In some regions (Votkinsk, Balakovo, Balashovo) we have improved our network and have introduced the new quality of our mobile internet by local out-of-home advertising and in-store campaigns.



•

We increased MTS network coverage in Moscow metro area, providing service to all metro train-cars base station. Everywhere in Moscow metro customers now have a strong network signal to make calls and use internet, even underground. This was communicated in a large Moscow ATL campaign, including TV flight and media formats.

Smart tariff plans

        In 2017, we focused on promotion of "My MTS" app opportunities in order to increase installs of the app and to reduce retail loading. We came out with a new promotion idea "You don't have to visit retail store any more, as you can get all services you need in "My MTS" app without leaving home."

        In 2017, MTS continued improving its Smart V&D billing plan range, and updated it to meet the requirements of Russia's changing telecom market:

•

Safe communication on all Smart billing plans. Due to the increased cyber threats to mobile devices, Smart billing plans were complemented with formidable security, protection against unnecessary subscriptions, malware, sudden charges on trips and loss of personal data.



•

Transfer of minutes and gigabytes on Smart billing plans. MTS motivated people to put their smartphones aside to enjoy happy moments here and now, as they didn't have to fear their

unused minutes and megabytes getting voided anymore. The campaign had the form of a captivating song entitled "Raise Your Byes" that enjoyed instant popularity and became viral across the whole net. To cater for our youth audience, we shot a separate music video featuring the "Khleb" ("Bread") comedy rap band. The music video unleashed a flurry of emotions and comments, making it number 1 in Russian YouTube trends.

•

Unlimited access to social networks and messengers on the Smart Bezlimitishe ("Unlimitedness") billing plan. In summer, MTS took an extraordinary approach to advertising by telling people that gyms were not the only place for them to show the best they can and that social networks required just as much effort.



•

New year offer. New customers had a chance to get 3 months of tariff for free during 2018.

Mobile payment and financial services

        In 2017, MTS continued to expand its "MTS Money Wallet" flagship financial service, adding more features to it. The website and "MTS Money" mobile application allow bringing consumer account, any banking cards a subscriber may have and his/her online wallet under one roof for people to be able to pay for mobile communication. Internet access, utilities, to make purchases and transfer money online.

Devices

        In 2017, the majority of devices-related communications campaigns were targeted at supporting the smartphones sales (of different price categories) in MTS retail, as well as supporting launches of global speciality products (iPhone 8, iPhone X, Samsung S8, Honor 9 etc.).

        Most of these campaigns were developed and implemented in cooperation with major device vendors such as Samsung, Huawei, Apple and LG.

        The main mechanics used in promotion (and communication) were: credit, cashback, strike price, mobile connection as a gift.

B2B offers

        Key initiatives for corporate segment have amplified the idea of our b2b positioning "MTS b2b products and services helps companies to increase effectiveness of their business."

        In 2017, we launched two product campaigns:

•

"Mobile employee" that helps to increase the efficiency of travelling employees (for example courier staff) and reduce transport spends; and



•

Cloud services with ATL campaign targeted on IT-specialists and financial staff of the companies.

        In addition, we continue to support our TV project "Business with high IQ" on RBK channel. It is a series of TV- spots, that demonstrate usage cases of our corporate clients who had effectively integrated our products and services in their business processes.

GPON and satellite TV

•

In Moscow we continued to promote the benefits of the GPON technology (fixed broadband and TV through the optic cable) focusing on communication of our high speed internet. In 2017 we launched a TV campaign focusing on our leader's image communication that "3 min of Muscovites have already chosen GPON from MTS/MGTS."

•

In other regions, we continued promotion of Home TV with two TV and several OOH campaigns. First campaign was devoted to the special offer on additional broadband services (just 50 RUB per month for: additional TV pack, service "TV everywhere" etc). The second campaign promoted 0 rub per month for interactive TV and various movies in "Video on demand" catalogue for free. In 2017 we also started using our partner's content in the TV campaigns. For example, in our latest TV campaign we used stills from movies "home Alone," "Kingsman," "Titanic" etc. from our partner "20th Century Fox."



•

In 2017, we also promoted satellite television. We aired the first federal TV campaign with a convergence offer allowing Smart billing plan subscribers to get satellite TV without additional subscriber fees. In the second campaign we set the aim to remove the "Satellite TV is expensive" barrier and promoted affordable prices for subscriber hardware just 2990 rubles for a complete set.

Other products and services

•

In 2017, we launched "Zabugorishe" ("Abroadest") a revolutionary offer on the roaming communication market (both a billing plan and a plan add on). Any "Zabugorishe" subscriber can make calls and use Internet both in Russia and abroad just like at home (within the usual home package). A large-scale 360 campaign, featuring Jean-Claude Van-Damme (to emphasize the scale) and Dmitry Nagiev, a Russian show business star, was launched in July 2017. The campaign's second flight was launched in December with Moscow and St. Petersburg as priority cities.



•

We continued to promote the benefits of the GPON technology in Moscow (the fastest fixed broadband in Moscow through optic cable) which allows us to provide highest-quality Broadband and TV services. In other regions with more sensitivity to pricing, we applied a more relevant "value for money" strategy.



•

MTS Hype V&D (voice & data) tariff plan in the third quarter 2017. We launched a federal campaign to promote "Hype," a first billing plan for teenagers. Hype allows customers to watch YouTube use social networks and messengers, stream music and play online games with no traffic limitations.

Global recognition

        In 2017, MTS got several awards on international Effic festival—for campaigns that promoted Smart tariff plan and "My MTS" mobile app.

        In 2014, MTS was included in the BrandZ™ Top 100 Most Valuable Global Brands 2014 ranking for the seventh consecutive year, as well as being recognized as the most valuable Russian telecom brand and made it to top 10 leading telecommunications brands in the world.

Sales and Distribution

        We have historically enrolled the vast majority of our subscribers through a network of independent dealers that operate numerous points-of-sale in places with high consumer activity, such as supermarkets, shopping centers, transportation hubs and markets. In 2009, in response to changes in the independent retail market, we began to develop our own proprietary retail network to more effectively control sales of SIM-cards and provide a platform to sell handsets and accessories. We organized our retail operations under a wholly owned subsidiary, RTC. RTC handles all functions relating to our retail operations, including the management of points-of-sale, the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets. It also requires us to secure optimal locations for our points-of-sale and monitors the effectiveness of their operations.

Table of Contents

        At the same time, in 2010, we focused on improving cooperation with a certain few of the large national and regional mobile handset retailers, such as Euroset and Svyaznoy, through which we had previously sold our products and serviced. In 2009, VEON Ltd. (VimpelCom), one of our main competitors, acquired a minority stake in Euroset, while in 2012, its ownership structure changed to accomodate an investment by MegaFon, another one of our main competitors, which equalized ownership with VEON Ltd. (VimpelCom) at 50/50. Throughout 2013 Euroset prioritized sales of its owners at the expense of MTS which impaired our ability to attract higher-quality subscribers and impacted profitability. Thus, MTS terminated its agreement with Euroset in May 2014.

        In 2013, we entered into an agreement with Svyaznoy to distribute SIM-cards and our sales through its outlets increased significantly during the year. We also continued to develop our monobrand retail chain, and in 2014, we could boast of attracting over half of our subscribers through our own proprietary distribution network. In 2014, Svyaznoy was the second in sales volume among MTS sales channels. In November 2014, Svyaznoy experienced changes in its ownership which led to the deterioration of MTS sales and an increase in competitors' sales beginning April 2015. While volumes declined throughout 2015, as of August 2015, MTS entirely ceased sales at Svyaznoy outlets. MTS designed a range of activities including the development of proprietary distribution network and stimulation of sales growth in regional distributors channel to compensate for the losses in subscriptions and achieve sales targets. We now realize over 63% of our SIM-card sales through our own monobrand retail chain while our retail arm is an increasingly important component of our differentiation strategy and ability to offer affordable handsets and accessories to our customers. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—The failure to launch and develop distribution network in Ukraine."

        Our competitors VEON Ltd. and MegaFon agreed on the termination of their joint ownership of Euroset outlets. Thus, MegaFon purchased the brand and the business. VEON Ltd. purchased 50% of points-of-sale. The deal affected the "improvement" of the mobile retail market. There was start of the transformation from the multibrand retail network to the monobrand retail network. In 2017 sales in the market reduced for the first time in Russian Federation. Moreover, the churn rate reduced also that confirmed the "improvement" of the mobile retail market.

        Our proprietary distribution network consists of MTS-branded franchise points-of-sale (third-party dealers operating under the MTS brand) and MTS-branded points-of-sale owned by us. As of December 31, 2015, we operated 5,133 points- of-sale, including 1,681 franchise points-of-sale and 3,452 points-of-sale owned by us. As of December 31, 2016, we operated 6,174 points- of-sale, including 1,839 franchise points-of-sale and 4,335 points-of-sale owned by us.

        In 2017, churn rate reduced, which improved the mobile retail market. As a result, the number of points-of-sale has decreased by 527 in 2017. There are 5,647 points-of-sale, including 3,938 points-of-sale owned by us.

        For newly acquired mobile subscribers in Russia, we link commissions payable to a dealer on a monthly basis to the amount of revenues we receive during six- to 12-month period from the date a subscriber is activated by a dealer. In addition, we have established caps, or a maximum commission amount payable to our dealers. The dealer commissions in Russia currently range between RUB 80 and RUB 2,800 per subscription.

        In Ukraine, we link dealer commissions to the tariff package sold, category of subscriber, subscriber revenue, the duration of a subscriber being active, city of subscription and sales channel. We have different commission structures based on whether the subscriber is Prepaid or Postpaid. For each new subscriber, a dealer typically receives a one-time commission payment at the time the contract is signed or monthly payments based on the revenue generated from the subscriber.

Table of Contents

        The dealer commissions in Ukraine for Postpaid tariffs consist of one-time commissions of 82 RUB to 98 RUB, that depends on the region of activation and we are entitled to retain the full commission amount if the subscriber stops using our services within five months following the month of activation. In addition, we may also pay monthly commission in an amount ranging from 30% to 36% of the revenues generated by the subscriber for a period from 6 to 12 months depending on the region of activation and dealer's plan achievement. Dealers are also rewarded (from 10 to 86 RUB) for providing a range of services for prepaid and postpaid subscribers, as well as a monthly amount of between 4 720 RUB and 102 611 RUB to exclusive dealers who sell exclusively VF Ukraine products and services. Prepaid tariff commissions for activation of a subscriber are linked to the territory where a dealer operates. The period during which we pay a dealer commission depends on our market share in that territory and may vary from 4 to 8 months and from 35% to 50% of the subscriber's monthly invoice.

        We believe that our method for paying commissions provides dealers with greater incentives to add new subscribers, reduces the risk of dealer fraud and improves our cash-flow management.

Competition

The Russian wireless telecommunications market

        Demand for wireless communications services in Russia has grown rapidly over the last years due to increased business activity, declining prices due to intensified competition among wireless communications providers and growth of new emerging consumers of telecom services such as IoT. As of December 31, 2017, overall wireless penetration in Russia was approximately 173.7%, or approximately 255.1 million subscribers, according to our estimates.

        The following table sets forth key data on Russia's wireless telecommunications market as of the dates indicated:

        The primary mobile providers in Russia include us, MegaFon and VEON (VimpelCom), each of which has effective national coverage in Russia. Competition is based on network coverage and quality, the level of customer service provided, roaming and international tariffs, local tariff prices and the range of services offered. For a description of the risks we face from increasing competition, see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—We face increasing competition in the markets where we operate, which may result in reduced operating margins and loss of market share, as well as different pricing, service or marketing policies."

environment and subscriber needs, all of which vary from region to region. Consistent with our marketing strategy, we have developed tariff plans to appeal to a broader market. The following table shows the mix between Prepaid and other subscribers, such as contract and corporate customers, for Russia and Ukraine for the periods indicated:

        We currently have a unified system of tariff plans offered to subscribers throughout Russia. The unified system is aimed at achieving such benefits as clarity, simplicity and transparency for prospective subscribers by offering the same set of tariff categories throughout Russia. Under each tariff category, we offer different tariff plans with different connection fees, per minute call charges and a wide range of value-added services.

        By advertising on a national rather than regional or local level, we have been able to streamline and reduce our advertising and marketing expenses through unified advertising campaigns throughout Russia. Furthermore, we are able to convey to consumers a more uniform perception of our brand and services.

Tariff Plans in Russia

        Currently, each of our tariff plans in Russia combines per minute usage charges, value-added services in packages and different monthly network access fees (with the exception of the prepaid tariff plans) designed for different market segments. Our tariff plans are currently divided into five categories—"Prepaid," "Smart," "Unlimited," "Data" and "Corporate"—with each category designed to target specific segments as follows:

•

Prepaid:  Prepaid tariff plans are geared towards consumers who use their mobile phones for personal communication. These plans do not have monthly subscription fees and the per-minute fee charges depend largely on the tariff plan chosen. We offer tariff plan "Super MTS," which allows to make up to 20 minutes of calls per day within MTS network for free. The "Super MTS" tariff plan varies depending on the region of the customer. In some regions we also offer the tariff plan "Red Energy," developed for different market segments, featuring flat price for calls within our network and calls to other networks.

Customer Payments and Billing

        We enroll new prepaid subscribers in an advance payment program. As of December 31, 2017, 84% of our consolidated subscriber base was enrolled in the advance payment program and 16% used a credit based system.

        Our advance payment system monitors each subscriber account and sends an advance warning on the subscriber's mobile telephone when the balance on the subscriber's account decreases below a certain threshold.

        Under the credit payment system, customers are billed monthly in arrears for their network access and usage. We limit the amount of credit extended to customers based on the customer's payment history, type of account and past usage. As of December 31, 2017, subscribers using the credit system of payment had credit limits of up to RUB 50.00 million for key corporate customers in Russia. When a credit limit is reached, we block the telephone number until the balance is settled. There are no credit limits established for certain exceptional, high loyalty customers.

        We provide "in full confidence" service, which allows our Prepaid customers who subscribe to this service to continue using services when the balance on the subscriber's account becomes negative. As of December 31, 2017, subscribers using the "in full confidence" service had a maximum credit limit of RUB 300 thousands. Customer service representatives can set individual credit limits for subscribers based on their payments and charge history (i.e., average balance usage) during the prior three months. When the credit limit is reached, our billing system blocks the phone number until the balance is settled. Similar to the credit payment system, the subscribers are billed monthly in arrears for usage. The invoice, which can be delivered to the customer by e-mail, fax, regular post and Internet, should be settled within 24 days. If the invoice is not paid five to seven days prior to the due date, the system sends an additional reminder. The telephone number is blocked on the 25th day if the invoice is not settled.

        In Russia, we offer our subscribers various ways to pay for our services, including cash or credit card, wire transfer, prepaid cards and express payment cards.

        We implemented Foris billing system in Russia in 2008. The Foris billing system allows us to offer all of our subscribers a uniform and consistently high level of service. It also supports the monitoring of account usage in real time. In addition, the system provides us with the ability to offer flexible tariff plans with various usage discounts and subscriber loyalty bonuses. Furthermore, we are able to provide our corporate subscribers with more sophisticated customized billing solutions. For example, our corporate subscribers who use multiple phone numbers in different regions of Russia now receive a single invoice, whereas our previous billing system could not support such a service.

        In Ukraine, our Postpaid corporate and high-end subscribers receive an invoice which must be paid by a specified date. If the subscriber fails to pay, we block the phone number until the balance is settled. Our contract subscribers, who make an advance payment, are able to continue using our services once they reach a zero balance or until their accounts reach the credit limit specified in their service agreements. When the limit for such a subscriber is reached, we suspend our services until the balance is settled. We determine account terms and credit limits for each subscriber based on the subscriber's account age, payment history and tariff plan.

        In Ukraine we provide services to our Prepaid customers for as long as the balance on their accounts remains above zero and/or the tariff plans allow to use free-of-charge services without having the positive balance on the account.

        In Ukraine we offer our subscribers various ways to pay for our services, including cash or card payment at the cash desk of the bank, through the recharge terminals, bank transfer from the current account (for legal entities), via internet and payment card of fixed nominal value.

Customer Service

Russia

        In order to attract and retain customers, we must ensure a high level of service at all points of customer assistance, care and billing. In each region where we operate, we have contact centers that provide customer service 24 hours a day, seven days a week. Contact centers provide different services to our clients through various channels (telephone, email, chat). Customer service representatives respond to various issues such as phone lock due to lack of payment, handset operation, roaming capabilities, service coverage and billing. A particular group of customer service representatives handles customer complaints and helps those who want to change their service terms. We use automatic systems and independent analysis for monitoring availability and customer satisfaction level of service in our contact centers regularly. We conduct outbound campaigns with the assistance of our employees in the outbound contact center and the laboratory of the customer relationship management inasmuch as we need to improve customer loyalty and promote our services.

        In 2017, we expanded the online chat channel in mobile application and self-service.

        In 2017, we started "Situational IVR." This service was reformed on the territory of the Russian Federation for all customers. When calling the Contact Centre, customers listen to information about some cases, which correspond to their needs with respect to the events and statistics. This project decreased up to 15% year-on-year number of calls to the contact-center.

        In 2017, we continued outsourcing call-center agents for the 1st line support for landline business customers. We decreased our costs for the 1st line by 30% as according to plan.

        In 2017, we started online robot for any incidents at back-office. Documents recognition will increase the automation of a number of operations up to 60%.

        In 2017, we continued to develop the mobile application for Android / iOS. New functionality allows mobile customers to manage their costs visually. This reduced number of calls to the contact center from customers with bill/service questions by 90%.

        The total number of customer complaints relating to technical failures within the network decreased by 5% year-on-year due to increased efficiency relating to the handling of such failures, automation systems for monitoring customer complaints in the CRM and other measures. Currently, if there is a technical failure causing a decrease in the quality of services, MTS necessarily informs customers about such failures via SMS, thereby eliminating the application of a customer with the same problem.

        In 2018, we plan to launch new services based on Situational IVR in mobile and landline business. Project showed an ability to reduce the number of calls into the contact center and increase the percentage of customers who have their problems solved up 20%.

Ukarine

        In Ukraine we made the customer assistance process more personalized by anticipating customer needs. We have enhanced the quality of our customer service as a result of the complete integration of our IVRs and billing. We have improved IVRs menu that enhance its utility. We continued to work on the improvement and expansion of self-service channels for subscribers. As part of online "self-service," we continued developing "self-care" functions through the web and IVRs (which provide, among other things, details of the subscriber's account, tariff plan specifications, amounts charged on credit cards, management of on-line service and charge details for contract subscribers). We also developed special services, such as shortened phone numbers, for broadband users and premium customers who require

assistance. We increased the number of services available to our customers in contact centers. We have a mobile version of the Internet Helper for smartphones. In 2013, we launched a new mobile application for Android OS. The application allows users to manage their account directly from their smartphones. We started the process of implementing an operational CRM system and the process of renewal of our contact centre technical platform. We also changed the approach to subscriber differentiation. In 2013, we finished the process of integration of our broadband subscribers into our system of customer service.

Customer Relationship Management (CRM)

        In 2015, we continued to develop operational CRM system. As a part of this process, we have migrated from local network for contact center to cloud technologies. We started user-friendly customer service (without strong standards) in contact center, whereby we were awarded with a Gold Medal for Best Customer Service in the ContactCenterWorld—The Global Association for Contact Center & Customer Services. We have also launched gifts for waiting at IVR before connection with contact center representative. Start of operation under Vodafone brand caused great impact for customer service from 4th quarter of 2015 and will continue to have an even greater influence later.

        In 2016, the mobile application for Android OS and iOS was developed, final completions of internal systems are carrying out. We performed equipment procurements within the New Contact Center project for Genesys platform implementation, which responds to all modern requirements in customer care. Also we paid the considerable attention to the solution of customer questions from the first contact in the most short time. The solution of requests from the first contact grew from 76% to 82%, and more than 81% customers complaints are solved in 24 hours. The Interactive Voice Response system was updated according to needs of customers and now more than 71% of customers are solve their questions via the IVR. Internet requests servicing was provided not only in Facebook official group and web site, but also was expanded on all space of social media (Facebook, Vkontakte, Forums, Internet editions etc.).

        In 2017, the first part of the project Operational CRM was implemented. Mobile application MyVodafone for Android OS and iOS was successfully launched, and the number of users exceeded one million subscribers at the end of the year. Genesys infrastructure was deployed within the framework of the New Contact Center Project and preparations for launching chat channels and outbound were completed. Service of the B2B segment—key account / national customers was successfully launched in own contact centers. Customer service processes are constantly being improved—first contact resolution rate (FCR24) has grown from 82% to 85%, more than 93% of customer complaints are resolved in 24 hours.

        In 2018, we are planning to launch the 2nd, 3rd and 4th parts of operational CRM, the implementation of the New Contact Center Project—the launch of the incoming calls channel, call recording systems and Work Force Management, the active development of the mobile application My Vodafone. Customer service in all points of contact will be unified to common standards. It is planned to continue service model improvement processes, reduction of load on Contact Center, redirection of inbound calls to digital channels. Chat and IVR bots are planned to be implemented. The opportunities of BigData and Real Time Marketing will be actively used—proactive service and increase of sales efficiency in the Contact Center.

Network Infrastructure—Technology Strategy

        Our technology strategy is formed in accordance with overall company's business strategy and intended to support the existing business operations, as well as to introduce new technologies allowing to launch new services in the future. Our technology strategy considers world technology trends in telecommunications.

Table of Contents

        The main focus of the technology strategy is consequent development of the network meeting future technology requirements: higher throughputs, lower latencies and flexible network core as enabler of the new services.

        LTE has the main priority while deploying Radio Access Network (67% of the RAN deployment was LTE in 2017) and 2G/3G investments decrease gradually in accordance with changes in network UE penetration structure and traffic migration.

        According to Technology Strategy we deploy LTE primarily in most efficient 1800 MHz band and use Carrier Aggregation, 256 QAM, MIMO 4×4 and other cutting edge techniques for better user experience.

        Our network is ready for VoLTE activation in some areas due to extensive LTE deployment in 2016 and 2017; massive VoLTE launch will take place in 2018.

        Our technology strategy implies consistent innovative technologies introduction to make our network futureproof and ready for the new services introduction. MTS network technically ready for IoT deployment and we have an understanding of how we will deploy first 5G networks, we have therefore started testing and initial preparation for 5G launch which will take place in 2020.

Network Infrastructure—Site Construction and Sharing

        In October 2014 MTS and VEON Ltd. (VimpelCom) has signed a contract about shared LTE networks deployment and operation. According to this contract one shared LTE network should be deployed for servicing subscribers of both companies.

        During 2015, 2016 and 2017 scope of the projects has expanded: shared networks are deployed in 43 of 85 regions of Russia.

        By the end of 2017 we had 2,772 LTE base stations shared with VEON Ltd. (VimpelCom) in 20 regions and VEON Ltd. (VimpelCom) had 2,481 LTE base stations shared with MTS in other 20 regions of Russia. Total amount of shared infrastructure nodes is 5,283 base stations servicing in 1800 MHz and 2600 MHz bands.

        In addition to network deployment investments and operational costs savings target architecture of the Site Sharing project includes frequency resources shared usage: by the end of 2017 networks in two regions of Russia run in shared 2600 band spectrum usage mode (MOCN concept). The area of MOCN implementation will be expanded in 2018. We are planning to add LTE TDD networks (3GPP Band 38) to a Project scope starting from 2018.

Network Infrastructure and Frequency Allocation

        We use switching and other network equipment supplied by Nokia Solutions and Networks, Ericsson, Huawei, Alcatel-Lucent, Samsung and other major network equipment manufacturers.

        In the Moscow license area, we have been allocated frequencies spanning 2 × 11.4 MHz of spectrum in the GSM 900 frequency band and 2 × 24.6 MHz of spectrum in the GSM 1800 frequency band for operation of a dual GSM 900/1800 network and UMTS900 network. In St. Petersburg and the Leningrad region, we have been allocated frequencies spanning 2 × 9.6 MHz of spectrum in the GSM 900 frequency band (including 2 × 1.6 MHz in the E-GSM band) and 2 × 18.2 MHz of spectrum in the GSM 1800 frequency band for operation of a dual GSM 900/1800 network.

        We have different amounts of spectrum in the 900 MHz band for GSM 900 and UMTS networks and in the 1800 MHz band for GSM 1800 and LTE networks in almost every region of the Russian Federation.

Table of Contents

        We have been allocated frequencies 1950-1965 MHz, 2010-2015 MHz and 2140-2155 MHz in the UMTS core frequency bands spanning 2×15 MHz (for FDD mode) and 5 MHz (for TDD mode) for UMTS network deployment for the entire territory of the Russian Federation.

        We have been allocated frequency bands 2540-2550 MHz and 2660-2670 MHz spanning 2 × 10 MHz and frequency bands 798. 5-806 MHz and 839.5-847 MHz spanning 2 × 7.5 MHz for LTE FDD network deployment for the entire territory of the Russian Federation. In addition, we have been allocated frequency band 2595-2620 MHz spanning 25 MHz for LTE TDD network deployment for the entire territory of the Russian Federation.

        We have frequencies allocated to us for the operation of GSM 900 and GSM 1800 frequency bands in all regions of Ukraine. The radio frequencies allocated to us for the operation of GSM 900 span from 2 × 4.4 MHz of spectrum in Chernigov region to 2 × 5.8 MHz in the Nikolaev, Lugansk, Chernovtsy and Kirovograd regions and in Kiev. We also have been allocated frequencies spanning from 2 × 20.0 MHz in the Kiev region to 2 × 26.6 MHz in the Dnepropetrovsk region for operation of GSM 1800 base stations. In addition, we have been allocated frequencies spanning from 453.35-457.1 MHz and 463.35-467.1 MHz in the CDMA-450 core frequency and bands spanning 3 × 1.25 MHz for CDMA-450 network deployment for the entire territory of the Ukraine. In 2015, we were allocated frequencies1950-1965 MHz and 2140-2155 MHz for UMTS network deployment for the entire territory of Ukraine.

        We believe that we have been allocated adequate spectrum in each of our license areas.

Network Infrastructure—Virtual Infrastructure

        The following projects have been launched in 2017:

•

IMS (IP Multimedia Subsystem) for 5G on NFV platform:

1-st stage was finished


2-nd stage was launched;

•

EPC (Evolved Packet Core);

        Public IaaS (Public Infrastructure as a Service) started with commercial servicing in 2017.

        A new multi-purpose module data-center will start operating in Nizhny Novgorod for future deployment of virtual platforms for telecommunication services and cloud services as well in 2018.

Network Infrastructure—Energy Infrastructure

        One of the main goals in Energy Infrastructure is to decrease operational costs for electric energy.

        According to legislative acts of Russian Federation electric energy payment categories were introduced in 2012. This payment category can be chosen by a consumer in a case of introduction electric energy accounting system, which allows hourly monitoring of electric energy usage and reporting to energy company with accepted procedure.

        Considering these conditions MTS has decided to deploy Electric Energy Accounting Automatic System (EEAAS). According to this trial projects of different EEAAS solutions were executed in different regions of Russia (Moscow, Nizhny Novgorod, Vologda, Saint Petersburg, Novosibirsk, Ekaterinburg and Republic of Karelia) in 2014-2015.

        EEAAS deployment projects was accepted in 2016 based on the analysis of those trials, System implementation started in 2016.

Table of Contents

        Introduction of the EEAAS will allow to:

•

Reduce electricity payments and thus reduce operational costs;



•

Increase level of precise accounting;



•

Implement energy usage management and control; track energy usage dynamics.

        The project implementation leads to reduction of payments for the electric energy: economy in 2017 reached 21% in the regions where EEAAS was deployed in 2016 and is projected at 12% in 2018 in the regions where the similar system was deployed in 2017.

        We are planning to deploy EEAAS in all regions of Russia.

Base Station Site Procurement and Maintenance

        The process of obtaining appropriate sites requires that our personnel coordinate, among other things, site-specific requirements for engineering and design, leasing of the required space, obtaining all necessary governmental permits, construction of the facility and equipment installation. In Russia, we use special radio planning software supplied by TEOCO Corporation to assess new sites so that the network design and site development are coordinated. This software can create digital cellular coverage maps of our licensed areas, taking into account the peculiarities of the urban landscape, including the reflection of radio waves from buildings and moving automobiles and supports all necessary technologies, such as 2G, 3G, LTE and Wi-Fi. To use these tools more effectively we purchase high quality 3D digital maps for more precise planning. Used together, these software tools enable us to plan base station sites without the need for numerous field trips and on-site testing, saving us considerable time and money in our network build-out.

        Base station site contracts are essentially cooperation agreements that allow us to use space for our base stations and other network equipment. The terms of these agreements range from one to 49 years, with the term of the majority of these agreements being one to five years. Under these agreements, we have the right to use premises located in attics or on top floors of buildings for base stations and space on roofs for antennas. In areas where a suitable base station site is unavailable, we construct towers to accommodate base station antennas, mainly on leased plots of land. We anticipate that we will be able to continue to use our existing GSM 900 base station sites and to co-locate GSM 1800, UMTS 2100 and UMTS 900 base stations at some of the same sites. In 2017, we continued to rollout LTE network and started the large-scale development of LTE1800 network, the latter amounted to 80.3% of the newly installed LTE base stations.

Network Monitoring Equipment

        We constantly control and monitor the performance of our network, call completion rate and other major key technical performance indicators. We use monitoring systems to optimize our network and to locate and identify the cause of failures or problems, and also to analyze our network performance and obtain network statistics. We have agreements with different suppliers for technical support services that allow us to obtain their assistance in trouble shooting and correcting problems with our network within the warranty period.

        To provide high quality service to our subscribers in Russia, we have a global network operation center ("GNOC") in Krasnodar. The GNOC experts have the technical ability to monitor network problems and unusual situations online in 60 regional branches of MTS in Russia including the region "Moscow" around the clock. Our maintenance department, staffed 24 hours per day, performs daily network integrity checks and responds to reported problems. Our technicians inspect base stations and carry out preventative maintenance at least once every six months.

Table of Contents

        The GNOC in Krasnodar allows us to centralize such functions as monitoring and controlling of equipment, network planning and optimization, and also helps to solve incidents related to service interruptions. The GNOC strengthens our network's reliability and safety, as well as creates the necessary conditions to launch and implement new technologies and network standards.

        We also have local operation and maintenance center in Voronezh which takes the form of outsourcing partnership with Nokia Solutions and Networks and is used for network monitoring in the 16 regional branches which had been included in the center of network planning and optimization "Center" before July 2016.

        In November 2015, a Global Fixed Network Operation Center (GFNOC) was launched in Nizhny Novgorod, thus completing the centralization process of the MTS mobile and fixed network management. The GFNOC combined functions of monitoring and controlling the equipment in 54 regions of Russia where MTS offers broadband Internet access, TV and fixed line telephony services. For the subscribers connected to these services the GFNOC acts as a single entry point for technical support. Under the GFNOC project a centralized unit was also set up which is responsible for the quality of the services provided to corporate customers with bundled packages of mobile and fixed communications. Our subsidiary company MGTS performs these functions in Moscow Region of Russia.

        With the Global Fixed Network Operation Center deployed, we put together all resources for management of the quality of provided mobile and fixed line voice services, data transmission via mobile and fixed networks, leased dedicated digital circuits and VPN channels and digital TV.

        In 2016, we also opened satellite TV operation and maintenance center in Moscow, which is used for monitoring head-end station and satellite TV services.

        Our networks in Ukraine, Armenia and Belarus are monitored by our local operation and maintenance centers in each country. In addition to the monitoring of network performance, those centers analyze network quality parameters, provide troubleshooting, regular and extraordinary reporting to the management and our headquarters. The monitoring of our network in Turkmenistan has been ceased in September 2017 due to cancelation of providing telecommunication services.

        The handling of any significant network problems and outages is monitored and coordinated at our headquarters, where we also manage the cross- functional coordination of our networks in all countries of operation.

Interconnect Arrangements and Telephone Numbering Capacity

        We operate various types of communications networks, including mobile cellular, DLD/ILD and local fixed line and zonal fixed line networks.

        Cellular operators must interconnect with fixed zonal, wireless, long distance and international telephone operators to obtain access to their networks and, via these operators, to the networks of other operators around the world. Cellular and fixed line operators must also obtain telephone numbering capacity to allocate to their subscribers. There are two categories of telephone numbers: "federal" 11-digit numbers (non-geographical numbering plan for cellular operators) and "local" seven-digit numbers (geographical numbering plan for fixed-line operators which can also be used as additional numbering capacity for mobile operators). In Moscow, both "federal" and "local" numbers have been used in the 11-digit format since the beginning of 2011. We have entered into various agreements for the provision of local telephone numbering capacity with several local telecommunications operators in Moscow and in other regions of Russia and in Ukraine. We have also built our own local networks in certain cities within Russia (including Moscow) to provide local telephone numbering capacity to our subscribers. Federal telephone numbering capacity is allocated by the government and we provide interconnect services to other operators in all regions of Russia. Our

fixed line zonal and local networks in Russia are interconnected with other operators. Zonal/local interconnect typically entails payment of a one-time connection fee per point of interconnect (E1) and a usage charge based on minutes of traffic. Operators with a Substantial Market Power may also charge a guarantee monthly usage fee in case traffic is less than 30 kmin per E1.

        The Ministry of Communications and Mass Media has allocated special numbering codes for federal 11-digit telephone numbers on a non-geographical basis to all the cellular operators. We believe that sufficient numbering capacity has been allocated to us for the development of our network. However, a combination of regulatory, technological and financial factors has led to the limited availability of local 7-digit telephone numbering capacity in Moscow and the Moscow region. Moscow's "495" code and the Moscow region's "496" code have already reached numbering capacity limits. As a result, the new "499" code was introduced in order to increase the Moscow numbering capacity, the "498" code was introduced to increase Moscow region numbering capacity and since 2011 "local" numbers have been used in Moscow in 11-digit format.

        To meet subscriber's demand and provide for an adequate inventory of numbering capacity, we previously entered into contracts with local fixed line providers for allocation of numbering capacity to us. However, the Ministry of Communications and Mass Media subsequently took the view that numbering capacity assigned to one operator could not be rented to other operators. Accordingly, we have entered into arrangements whereby fixed line operators make their numbers available to our subscribers via agency contracts between the subscribers and us acting on behalf of such fixed line operators. Our right to use numbering capacity ranges from five years to an unlimited period of time. As a result of our merger with Comstar, we have decreased the use of local numbering capacity of other operators. As of December 31, 2017, we had numbering capacity (federal and local) for approximately 34.26 million subscribers in the Moscow license area.

        To provide our subscribers in Russia with DLD/ILD services, we have interconnect agreements with national operators Rostelecom, MTT (an affiliate of Sistema until March 18, 2009), VEON Ltd. (VimpelCom) and other national transit operators. We have also built and operate our own DLD/ILD network, which allows us to interconnect directly to foreign operators and thereby decrease our interconnect costs. Most interconnect fees for connecting users of other operators' fixed line and wireless networks to our network are based on a one-time connection fee and usage by minute which varies depending on the destination called.

        Russian legislation provides that fixed line operators with a substantial market power cannot refuse to provide interconnect or discriminate against one operator in relation to another, and the interconnect rates of operators with a Substantial Market Power are regulated by the government. See "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Regulation in the Russian Federation—Competition, Interconnect and Pricing" and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices, which may diminish our market share and result in a loss of revenues and margins."

        Interconnect and traffic transit between the networks of mobile operators in Russia occurs through direct channels connecting the switches of the different mobile operators within the same city; through the network of transit long distance operators, which connect the networks of different mobile operators in different cities or through our own DLD/ILD network. For domestic long distance traffic transit we use our DLD/ILD network and networks of different national operators, including among others: MTT, Rostelecom and VEON Ltd. (VimpelCom). For ILD traffic transit we primarily use our DLD/ILD network which is interconnected with 49 international carriers. We also have an interconnect between the DLD/ILD MTS network and the ILD networks of our subsidiaries, Vodafone Ukraine and MTS Armenia, in order to provide transit for international traffic.

        In Ukraine, mobile operators are allocated numbering capacity by the NCCIR (National Commission for the State Regulation of Communications and Informatization). We believe that sufficient numbering capacity has been allocated to us in Ukraine for the development of our mobile network. We also believe that we have been allocated sufficient fixed line numbering capacity with respect to the cities in which we are developing our fixed line networks.

Handsets

        Nearly all of our handset sales consist of tri-band GSM 900/1800/1900 and dual-band UMTS 900/2100 handsets, except for certain models in the low cost segment. Those handsets, which function in the GSM 900, GSM 1800 and PCS-1900 standards, provide users with greater automatic roaming possibilities in Russia, Europe, the United States and Canada. All LTE handsets support bandwidth LTE-FDD 1800 MHz (Band 3), 2600 MHz (Band 7), 800 MHz (Band 20) and LTE-TDD 2600 MHz (band 38), also there are smartphones in our sales with LTE Advanced support. In 2017, we initiated the process of implementation Voice over LTE and WiFi Calling functions.

        From 2009, RTC, our wholly-owned subsidiary, started handling all functions relating to our retail operations, including the purchase and sale of handsets and accessories and subscriber enrollment at our retail outlets. RTC has entered into arrangements with Apple, Sony, Samsung, Nokia, Alcatel, Xiaomi, Philips, Huawei, ZTE and others to purchase handsets. In 2017, we continued our cooperation with A-brand smartphone vendors. We also offer an array of mobile telephone accessories. Since 2009 we have been successfully selling MTS branded phones.

Fixed Line Services

        We offer fixed line communications services in over 185 cities across Russia, covering a population of over 53 million people.

        Our other fixed line operations include the following communications services: voice, data and Internet and pay-TV services for corporate and residential subscribers, as well as the provision of interconnect services to other communications operators and numbering capacity to their subscribers. Based on TMT Consulting data, as of December 31, 2017, we were the largest operator in the Moscow residential broadband market in terms of subscribers, with a 33.1% market share. We also operate in Ukraine and Armenia, where we provide digital telephony communications services, data transmission, Internet access and the renting of channels. For a list of the telecommunications licenses held by us, see "Item 4. Information on Our Company—B. Business Overview—Regulation of Telecommunications in the Russian Federation and Ukraine—Licenses."

Customers and Services Offered—Moscow Fixed Line Operations

        We provide fixed line communications services through our subsidiary, MGTS, which is the incumbent fixed line PSTN operator in Moscow. MGTS owns Moscow's PSTN infrastructure, including switches, a transmission network, underground ducts, and owns or holds leases to properties housing its offices and equipment.

        As of December 31, 2017, MGTS had approximately 3.6 million active lines in service, a cable network of over 61,698 km, a fiber optic network of over 40,563 km and 2,150 payphones. Currently, MGTS has focused its efforts on the deployment of GPON, IP/MPLS technologies and an IMS core. The old SDH equipment is being removed which results in the decreased number of E1 streams, a reduction in the copper network and the respective extension of the fiber- optic network. MGTS also develops new services for IP TV, and MVNO as the convergent service for mobile and fixed telephony.

        The total installed capacity of the telephone network reached 2.75 million numbers on the TDM area (Time Division Multiplexing) and 5.18 million numbers on the IMS area (IP Multimedia Subsystem) as of December 31, 2017.

        Residential subscribers accounted for approximately 83% of MGTS' total lines, corporates for 9% and public sector subscribers for 8%, as of December 31, 2017. Residential subscribers accounted for approximately 83% of MGTS' total lines, corporates for 9% and public sector subscribers for 8%, as of December 31, 2016. Residential subscribers accounted for approximately 82% of MGTS' total lines, corporates for 10% and public sector subscribers for 8%, as of December 31, 2015.

        MGTS holds licenses and regulatory approvals to provide, among others, the following services:

•

local telephony;



•

DLD/ILD voice telephony through licensed DLD/ILD operators, including us;



•

interconnect to other operators;



•

Internet and data transmission, including leased DLD/ILD services;



•

•

telecommunications services associated with cablecasting;



•

movable radiotelephony services; and



•

measures and (or) services for the protection of State secrets;



•

capital construction projects engineering.

        As the only licensed PSTN operator in Moscow, MGTS is considered a natural monopoly under Russian antimonopoly regulations. Consequently, substantial part of services provided by MGTS are subject to governmental regulation. The Federal Antimonopoly Service of the Russian Federation regulates MGTS' tariffs for voice telephony services provided to its PSTN subscribers, including monthly subscription fees, installation fees and local call charges. Revenues from regulated services are accounted for approximately 42% of service operating revenues of our Moscow fixed line operations in 2017, 49% in 2016 and 51% in 2015. The percentage decline is connected with gradual growth of operating revenues from non-regulated services as a proportion of the overall operating revenues in 2017, 2016 and 2015. The Federal Antimonopoly Service of the Russian Federation sets the tariffs MGTS can charge taking into account cost of services, network investment and a certain profit margin, and the current tariffs fully compensate MGTS for the cost of services provided to residential and government subscribers. According to Russian legislation, MGTS is allowed to petition the Federal Antimonopoly Service of the Russian Federation for tariff increases upon certain conditions, such as inflation or increases in the cost of services. Historically, MGTS has petitioned the relevant Russian government agency for tariff increases once or twice per year. The Federal Antimonopoly Service of the Russian Federation has permitted MGTS to increase its tariffs several times.

        MGTS also provides a number of unregulated services. According to Russian legislation, DLD/ILD services provided by licensed non-monopoly operators, data transmission services, value-added services and a number of other services are not subject to tariff regulation. Among others, MGTS provides the following unregulated services:

•

various value-added services, including call forwarding, call waiting, call holding, caller ID, provision of second direct inward dialing (DID) number;



•

Internet access for residential subscribers and corporates;



•

IP TV for B2C and B2B subscribers;



•

MVNO mobile telephony and Internet;

alarm signaling;



•

domestic maintenance services, including electric installation, sanitary engineering, cleaning, computer emergency, and consumer electronics installation;



•

video-surveillance; and



•

rent of space for telecommunications equipment of other operators connected to MGTS' network.

        MGTS does not have license to provide DLD/ILD communications services directly to its subscribers but must route such traffic through a licensed DLD/ILD operator. As a result, DLD/ILD traffic originated by MGTS subscribers is carried either by us, with these services included in MGTS' monthly bill, or by other providers of DLD/ILD services, who bill MGTS subscribers directly or pay MGTS an agency fee for processing their bills.

        The following table presents certain operating data for our Moscow fixed line operations as of and for the years ended December 31, 2015, 2016 and 2017.

        MGTS' subscriber segments and the services provided to each subscriber segment are further described below.

Customers and Services Offered—Other Fixed Line Operations

        We provide fixed line communications services to corporate, operator and residential subscribers in over 185 cities throughout Russia. Specifically, we offer local voice, DLD/ILD voice, data and Internet and pay-TV services to our subscribers. Some of the interconnect tariffs we charge other telecommunications operators for in Moscow and certain other cities are regulated by the Russian government. We believe our fixed line subscribers typically evaluate our service and product offerings based on such factors as price, technology, security, reliability and customer service.

        The following table presents certain operating data for our other fixed line operations in Russia as of and for the years ended December 31, 2016 and 2017.

Corporate subscribers

        We target corporate subscribers covering a range of industries, such as business centers, hotels, financial institutions, professional services firms, consumer goods companies, manufacturers and companies involved in extractive industries, among others. These subscribers vary in size, ranging from large multinational and Russian corporations with thousands of employees to small-and medium-sized enterprises with up to several hundred employees. As of December 31, 2017, we had approximately 41,000 voice and 80,000 Internet corporate subscribers.

        As further described below, we offer voice, data transmission and Internet and various value-added services to our corporate subscribers.

        Voice Services.    We provide a full range of other fixed line voice services to corporates in Moscow, the Moscow region and other selected regions of Russia, which include local, zonal, and DLD/ILD services using our transmission network and leased capacity between major Russian cities. We also provide integrated voice and data services, voice over frame relay and certain integrated services digital network ("ISDN") services.

        Data Transmission and Internet Services.    We offer high quality data transmission services to corporates, which allow for data exchange between their various branches or offices located within Russia and internationally. For data transmission services, our network is capable of transferring data at speeds of up to 10 Gbps and utilizes various technologies, such as 10 GE, GE, ATM, TDM, VPN-MPLS/VPLS, GPON, Microwave radio relay (MRR), xDSL, LTE and Wi-Fi to provide high quality solutions at a relatively low cost. We endeavor to ensure the reliability of network connections by utilizing a full reservation approach to back up all elements of the network.

        In addition, we offer a wide range of Internet services to corporates, including broadband Internet access, VoIP, VPNs and data center services using the following technologies: (1) NGN (up to 10

Gbps), (2) GPON (up to 1 Gbps), (3) xDSL (up to 100 Mbps), (4) radio Ethernet (up to 300 Mbps), (5) MRR (up to 1 Gbps), (6) Wi-Fi (up to 150 Mbps), and (7) LTE (up to 100 Mbps). We also provide continuous flexibility to upgrade their network capacity to handle additional Internet services. For example, we often integrate data transmission and Internet services for our clients as they expand their operations and need to interconnect and exchange data with newly opened offices and/or branches.

        We also provide security services, such as Anti DDoS-protection and various AntiVirus solutions.

        We offer a broad range of Internet packages that vary in terms of data transfer speeds and pricing, with higher tariffs for faster uploading and downloading capabilities. Corporates with GPON broadband Internet packages generally experience data transfer speeds between 1 Mbps and 1 Gbps. In addition, we offer a premium broadband Internet service over our NGN in which subscribers enjoy data transfer speeds between 1 Mbps and 10 Gbps. The NGN provides subscribers with the benefit of the same uploading and downloading data transfer speeds, whereas Internet subscribers using an xDSL/GPON connection upload at speeds that are much slower than the one at which they can download.

        We also utilize MGTS' PDTN to provide high-speed reliable Internet services and create VPNs for our corporates.

        Leased Channels.    We provide corporate clients with the ability to rent high speed data channels. These "leased channels" are dedicated lines of data transmission.

        Value-Added Services.    We provide corporates with several value-added services, including Autosekretar and integrated solutions. The Autosekretar service is based on our proprietary IN and is designed to help our corporates manage the reception and servicing of a large volume of incoming calls. The unique multi- channel telephone number assigned to customers will not change even if the customer moves to a different location in Moscow, and does not require the customer to install any equipment. In addition, this service allows all incoming calls to be transferred to other fixed or mobile telephone numbers in Russia or in other countries. The IN identifies a subscriber by phone number, phone card or password, which allows our customers to bill their subscribers for services and, if necessary, block access for subscribers who have a negative balance on their account.

        In addition, we serve as general contractor for the provision of a full range of integrated solutions to subscribers wishing to establish a modern integrated communications infrastructure. Each solution is customized for subscriber- specific needs. In developing these customized networks, we are able to offer the following range of services: site survey, cost analysis and optimum project planning, assistance with government-related documentation, supply of equipment and operational, technical and maintenance support on an ongoing basis. Once the infrastructure is established or renovated, as the case may be, we typically provide digital voice communications, voice intelligent services, high-speed Internet services, videoconferencing and other data transmission services. We intend to expand our service offerings to include customer premises management and network-centric IT solutions.

        Fixed mobile convergence.    Based on our fixed and mobile networks, we offer fixed-to-mobile convergence services to corporate clients providing use of their mobile phone as an extension of their private branch exchange ("PBX"). We also provide access to corporate IP-networks from a mobile phone via GPRS/EDGE/3G/4G.

Operators

        We operate fixed-line local and zonal networks in Moscow and other cities for provision of telephony services to fixed-line subscribers and additional local numbers to mobile subscribers. In order to lower the costs of intercity and international traffic transition, we put into operation an intercity international network in December 2008.

Table of Contents

        According to our estimates, together with MGTS, we had approximately 77% of the total active numbering capacity in Moscow as of December 31, 2017. We now have approximately 204 local fixed nodes in 62 regions of Russia, including Moscow, and 40 zonal fixed networks to provide telephony services to subscribers. Our integrated intercity/international network is interconnected to more than 49 international operators. As of December 31, 2017, we had total more than 1,660 interconnect agreements with national and international operators for interconnection of our networks, including fixed, mobile and Intercity/International networks.

Residential subscribers

        We offer voice, Internet and pay-TV services to residential subscribers.

        Voice Services.    We provide voice services to residential and corporate subscribers. Like corporate subscribers, residential subscribers in each of the regions that we are present in seek a full range of high quality voice services equivalent to those provided in Western Europe. In addition to "basic" voice telephony services, we provide a number of additional services, such as call forwarding, call transferring, call waiting, conference, voicemail and Caller ID, among others.

        Internet Services.    We offer broadband Internet services to residential subscribers throughout Russia. As of December 31, 2017, we had 9% market share in the Russian Federation together with Moscow where we had a 33.1% share, based on TMT Consulting data. Depending on the Internet connection speed, we charge residential subscribers a subscription fee of RUB 300-RUB 1,600 per month in Moscow and a subscription fee of RUB 250-RUB 1,900 in other regions of Russia. We do not charge a connection fee in Moscow and in most of the Russian regions.

        Pay-TV.    We operate a TV service based on IPTV service over ADSL and GPON technologies in Moscow. In addition, we offer pay-TV services based on DVB-C (digital television via cable connection), analog cable transmission and MMDS (wireless cable) technologies in most of the regions in which we are present. Since November 2013, we connect our subscribers only to the TV with digital quality. Special auxiliary equipment (set-top box) allows pay-TV subscribers to access more than 170 channels of digital quality, including 40 channels of HD quality from a home television. International and Russian channels are included as part of the base services package.

        Our pricing structure is designed to appeal to large numbers of consumers with various interests and purchasing power, and varies significantly between regions. We charge a subscription fee of RUB 99-RUB 2,000 per month in Moscow and a subscription fee of up to RUB 170-RUB 400 in other regions of Russia, depending on the number of channels included in the package. We also offer bundled Internet and pay-TV services for RUB 550-RUB 1,900 per month in Moscow and RUB 450-RUB 1,980 in certain other regions of Russia, depending on the speed of the Internet connection, the number of pay-TV channels being provided and level of competition in a particular region.

Sales and Marketing

Moscow fixed line operations

        As by 2017, the MGTS network modernization and re-equipment to GPON technology was mostly completed, the main focus was shifted to the growth of GPON-based services penetration and subscriber loyalty increase. To accomplish this free packaging was introduced, a number of new balanced convergent bundles with high-speed fixed and mobile internet was offered to the market, the first own bonus program implemented and video surveillance service extended. To retain subscribers MGTS offered the contractual tariff, including Internet-access and voice for 700 RUB and smartphone Samsung Galaxy J120 for 1 RUB per month.

Table of Contents

        Aside from traditional telecom services, MGTS started offering household services, arranging a separate business-line.

        By the end of 2017, 1.85 million B2C and B2B subscribers were transferred to GPON. In 2018, MGTS will continue its strategy of transformation into the multi-service operator, providing traditional telecom and innovative Internet-based services.

Other fixed line operations

        Our target customers include corporate, operator and residential subscribers.

        To promote our product and service offerings, we use various communication channels for advertising and marketing, including direct marketing, printed mass media, television, Internet, radio, directories, outdoor advertising, advertising in the subway, special promotions and cross promotions. Through these various advertising and marketing channels, we intend to further develop our brand recognition. Our marketing strategy is designed to create a unified brand for each of our various product and service offerings with the aim of becoming a single source for all of our subscribers' communications needs.

        We also actively promote our services to existing subscribers with special bundled product offerings aimed at servicing their communication requirements and enhancing subscriber loyalty. Our advertising and marketing materials are aimed primarily at the promotion of MTS brand. All fixed-line products are offered and marketed under this brand. However, when we enter new markets and acquire companies, we have to use both brands in advertising—MTS brand and the acquired brand. This is done to decrease churn as customers tend to express strong loyalty towards local brands. We then gradually decrease presence of the acquired brand and this allows us to make MTS a market leader in a given region in future. Our advertising and marketing efforts are designed to convey a positive image of us to the market as a leading communications operator focused on customer satisfaction.

Network Infrastructure

Network Infrastructure—Transmission Networks

Backbone and Internet Networks

        Mobile, fixed and inter-carrier aggregated traffic increased in 2017: downlink (towards uses) data throughput reached 2.88 Tbps (1.9 Tbps in 2016), uplink (from uses) data throughput reached 1,13 Tbps (0,752 Tbps in 2016).

        The size of MTS fiber-optic networks increased by 13,435 km in 2017 and reached 226,435 km in total, thanks to deployment of the following fiber optic lines: Tynda—Yakutsk; Komsomolsk-na-Amure—Yuzhno-Sakhalinsk (including an underwater crossing of Tatarsky Strait, in partnership with the TTK).

        Additionally, in 2017 the following backbone links long-term lease (iRU, in partnership with "Big Three" operators) were deployed:

•

Vologda—Arkhangelsk—Petrozavodsk—Murmansk (10G—VEON Ltd. (VimpelCom));



•

Komsomolsk-on-Amur—Okha—Magadan and Okha—Petropavlovsk Kamchatskiy (10G—Rostelecom); New Urengoy—Norilsk (10G—Edinstvo)

Convergent network

        According to deployment plans, the following projects were executed in 2017:

•

New MBH nodes were deployed:1319; replacement of obsoleted MBH equipment is ongoing.



•

Micro wave links were deployed: 3022.

        We continue the shared network deployment and links interchange projects with other operators and have signed the memorandum of understanding with respect to the potential projects. Memorandum defines a list of directions (parts of fiber-optic communication links) which are mutually interesting for both participants. Summarized length of provided communication links is approximately equal on both sides.

        Management and monitoring systems virtualization is ongoing. Unified system for link facilities based on GE Small World solution launched in production mode in the fourth quarter 2017.

        As a part of evolution of IPBB (IP Backbone) network equipment modernization is ongoing. The projects assumes replacement Cisco 7600 nodes for ASR9000 nodes due to an end of a support of 7600 nodes. The project is planned to be finished at 2019.

        In 2017, we performed an estimation of pilot project SDH networks dismantling and plan to launch the pilot in 2018.

Public Switching Telephone networks (PSTN)

        The network infrastructure we maintain in Moscow is substantially different to the infrastructures we use in the regions. In Moscow, primarily we have organically grown, while our regional development has largely been through the acquisition of companies with different business models and a focus on different services. As a result, the network infrastructures in the regions outside Moscow and the technologies used to support such infrastructures are different from the network infrastructure established in Moscow and which we currently own. Now telephone network in Moscow and Moscow region has a capacity of more than 1,100,000 telephone numbers.

        All of our PSTN switching centers (TDM and Soft switch) are connected to a digital transport network, which uses SDH and IP technology. The network ensures connectivity with a digital equipment of PSTNs of other operators.

        The SDH network will be operated to support existing clients, but we also provide the moving traffic and clients from SDH/TDM technology to IP.

        The management of the transport network and digital PSTN is carried out remotely from network operation centers.

        As of December 31, 2017, in Moscow and the Moscow region we had a wireless broadband network including about 500 base and subscriber stations in the 5-6 GHz frequency band and also near 130 radio-relay lines in the 70-80 GHz frequency band.

        For the provision of Internet access, IP-telephony and other services, we have our own IP network, the core of which is constructed as IP MPLS rings with routers connected to each other by means of 10 GE channels. In addition, separate routers are used for inter-carrier connections and are connected to the core routers by means of 10 GE interfaces.

Russia

        As of December 31, 2017 we provided cable Internet access to about 9.3 million households and cable TV access to about 9.8 million households. The access equipment used are Ethernet switches, IP DSLAM and Optical Receivers. We mainly use FTTB technology for Internet (8,6 million households) and CATV access, which can provide speeds up to 1 Gb/s per building and about 250 channels CATV (analog and digital). In 2011, we started to roll-out DVB-C technology for a cable TV service. Currently, we have digital TV service (DVB-C&DVB-S2) in 187 cities and localities with 3.1 million of subscribers. In 2014, we started to roll-out an advanced hybrid TV service (DVBC/DVB-S2/IPTV+IP/VOD, CatchUp). By December 2017, we launched Hybrid TV platform with an IPTV commercial service in Moscow, Moscow Region (MGTS), Saint Petersburg and Leningrad region, DVB-C/IP Hybrid commercial service in 90 regional cities and DVB-S2/IP Hybrid commercial service all over Russia. During 2017 in DVB-C and DVB-S networks MTS launched broadcasting of 4K/UHD channels and MTS TV headend now supports HEVC (H.265) encoding. Total number of connected hybrid TV users is about 0.47 million. Also during 2017 there was a launch of first set of upgrades to the Hybrid TV product including setup of infrastructure for quick adding of external interactive services together with different Internet partners (Platbox, Wikipedia, Yandex and set of online TV services: IVI.ru, MEGOGO, AMEDIATEKA). In 2018 we are planning to launch major upgrade of VoD service and launch 2nd set of upgrades to the product including Wi-Fi support, new UI, significant search function upgrade and accelerating and more interactive services with our partners. In the first half of 2018 we are also planning to launch TV statistics and usage analysis system. During 2018 the final decision should be made regarding launch of unified TV platform for fixed and mobile devices merging current services of mobile and fixed digital TV in one TV product that will be replacing current Hybrid

TV platform by 2020. During 2018, we are also planning to add more 4K/UHD services into our DVB-C/S and IPTV networks and launch TV gaming on Hybrid TV STBs.

        In Moscow and regions as an Internet traffic supplier, we mainly use MTS own IP Backbone network.

        The acquisition of Comstar provided us with an opportunity to use MTS fiber optic lines for fixed network development. Optical network construction in cities is carried out on the basis of fixed and mobile business needs. When we modernize and construct new networks, we deploy fixed and mobile equipment on the basis of "collocation" method

Principal suppliers

        Our principal suppliers are: NVision Group, subsidiary of the Group and integrator; Huawei, Iskratel, Oracle—PSTN switching equipment and SBC; Ericsson, Garmonica, Cisco Systems—equipment of Digital TV station; Irdeto, Verimatrix—CAS TV systems; Ericsson—Hybrid TV platform; Cisco Systems, Huawei, D-Link—FTTB core and access; Juniper Networks, Huawei, ECI Telecom, Tellabs and Alcatel Lucent for a transport network equipment.

        All of our equipment is supplied directly through authorized dealers

Seasonality

        Our results of operations are impacted by certain seasonal trends. Generally, revenue is higher during the second and third quarter due to increased mobile phone use by subscribers who travel in the summer from urban areas to more rural areas where fixed line penetration is relatively low, as well as an increase in roaming revenues and guest roaming revenues during these quarters. Quarterly trends can also be influenced by a number of factors, including new marketing campaigns and promotions, and may not be consistent from year to year.

Regulation of Telecommunications in the Russian Federation and Ukraine

Regulation in the Russian Federation

        In the Russian Federation, the federal government regulates telecommunications services. The principal law regulating telecommunications in the Russian Federation is the Federal Law on Communications, which provides, among other elements, for the following:

•

licensing of telecommunications services;



•

requirements for obtaining a radio frequency allocation;



•

equipment certification;



•

equal rights for individuals and legal entities, including foreign individuals and legal entities, to offer telecommunications services;



•

fair competition;



•

freedom of pricing other than pricing by companies with a substantial position in public telecommunication networks; and



•

liability for violations of Russian legislation on telecommunications.

        The Federal Law on Communications came into force on January 1, 2004. The Federal Law on Communications creates a framework in which government authorities may enact specific regulations. Regulations enacted under the legislative framework in place prior to the enactment of the Federal

Law on Communications continue to be applied to the extent they do not conflict with the Federal Law on Communications.

        The Federal Law on Communications, which confers broad powers to the state to regulate the communications industry, including the allocation of frequencies, the establishment of fees for frequency use and the allocation and revocation of numbering capacity, significantly modifies the system of government regulation of the provision of communications services in Russia. In particular, licenses to provide communications services in territories where frequency and numbering capacity are limited may be issued only on the basis of a tender, whereas according to the Government Decree No. 480 dated May 24, 2014, licenses to provide communication services with frequency spectrum—only on auction basis. In addition, the Federal Law on Communications provides for the establishment of a "universal services reserve fund" which is funded by a levy imposed on all operators of public networks, including us.

Regulatory Authorities

        The Russian telecommunications industry is regulated by several governmental agencies. These agencies form a complex, multi-tier system of regulation that resulted, in part, from the implementation of the Federal Law on Communications, as well as from the large-scale restructuring of the Russian government in March 2004 and subsequent restructuring in May 2008. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Countries of Operation—Political and Social Risks—Political and governmental instability in Russia and other countries of our operations could materially adversely affect our business, financial condition, results of operations and prospects and the value of our shares and ADSs."

        The Ministry of Communications and Mass Media is the federal executive body that develops and supervises the implementation of governmental policy in the area of communications and coordinates and controls the activities of its subordinate agencies. The Ministry has the authority to issue certain regulations implementing the federal law on communications and other federal laws.

        The Federal Service for Supervision of Communications, Information Technologies and Mass Media is a federal executive body that supervises and controls certain areas of communications and information technologies, including:

•

the issuance of licenses and permissions in the area of communications and information technologies;



•

the registration of radio-electronic and high-frequency equipment;



•

the assignment of radio frequencies based on decisions taken by the State Radio Frequencies Commission and registration of such assignments;



•

the technical supervision of networks and network equipment throughout Russia;



•

the monitoring of compliance by network operators with applicable regulations, terms of their licenses and terms of the use of frequencies allocated and assigned to them;



•

the enforcement of equipment certification requirements;



•

the examination of electromagnetic compatibility of equipment with existing civil radio-electronic equipment;



•

the organization of tenders with respect to licenses in the sphere of communications;

        The Federal Communications Agency is a federal executive body that implements governmental policy, manages state property and provides public services in the area of communications, including the allocation of numbering capacity and the certification of equipment for compliance with technical requirements.

        The State Radio Frequencies Commission is an inter-agency coordination body acting under the Ministry of Communications and Mass Media which is responsible for the regulation of the radio frequency spectrum, develops long-term policy for frequency allocation in the Russian Federation and decides on the allocation of frequency bands.

        The Federal Antimonopoly Service (FAS) is a federal executive body that supervises competition regulations and enforces the Federal Law on Protection of Competition and the Federal Law on Natural Monopolies and the regulations enacted thereunder. The FAS controls certain activity of natural monopolies, including monitoring their execution of certain obligatory contracts, and can issue mandatory orders as provided for in the Federal Law on Natural Monopolies. In addition, the FAS regulates certain tariffs in the sphere of telecommunications, including the tariffs on the local, intra—zone and DLD calls by subscribers of public switched telephone networks and installation and subscription fees.

        Other regulatory authorities.    The Federal Service for the Oversight of Consumer Protection and Welfare is responsible for the enforcement of sanitary regulations, including some authority over the location of telecommunications equipment, and supervises the compliance of companies with the regulations relating to the protection of consumer rights. The Federal Service for State Registration, Cadastre and Cartography is responsible for registering certain telecommunications infrastructure that is considered real property in accordance with Government Decree No. 68 dated February 11, 2005. The Federal Service for Financial Monitoring (Rosfinmonitoring) is a federal executive body responsible for countering money laundering and terrorism financing. Mobile operators are to comply with Federal Law No. 115-FZ dated August 7, 2001 "On combating money laundering and terrorist financing."

Licensing of Telecommunications Services and Radio Frequency Allocation

        Telecommunications licenses are issued based on the Federal Law on Communications and Government Decree No. 480 dated May 24, 2014 on Bidding Process (Auctions, Tenders) for Receipt of Telecommunications License. Under these regulations, licenses may be issued and renewed for periods ranging from three to twenty-five years. Several different licenses to conduct different communication services may be issued to one entity. Provided the licensee has conducted its activities in accordance with the applicable law and terms of the license, renewals may be obtained upon application to the Federal Service for Supervision of Communications, Information Technologies and Mass Media. Officials of the Federal Service for Supervision of Communications, Information Technologies and Mass Media have broad discretion with respect to both issuance and renewal procedures.

        A company must complete a multi-stage process before the commercial launch of its communications network. A company must:

•

receive a license from the Federal Service for Supervision of Communications, Information Technologies and Mass Media to provide communications services;



•

obtain approval to use specific frequencies within the specified band from the State Radio Frequencies Commission if providing wireless telecommunications services; and

114

---

Table of Contents

•

obtain permission from the Federal Service for Supervision of Communications, Information Technologies and Mass Media for network operations. To receive this permission, a wireless telecommunications services provider must develop a frequency assignment and site plan, which is then reviewed and certified by the Federal Service for Supervision of Communications, Information Technologies and Mass Media for electromagnetic compatibility of the proposed cellular network with other radio equipment operating in the license area. The Federal Service for Supervision of Communications, Information Technologies and Mass Media has discretion to modify this plan, if necessary, to ensure such compatibility. Effective January 1, 2004, licenses may be transferred in case of mergers or other reorganizations of the licensee upon application by a transferee as a new license holder. Additionally, the Ministry of Communications and Mass Media has declared that agreements on the provision of telecommunications services must be concluded and performed by the license holder.

        If the terms of a license are not fulfilled or the service provider violates applicable legislation, the license may be suspended or terminated. Licenses may be suspended for various reasons, including:

•

detection of violations which may cause damage to rights, interests, life or health of individuals or to interests of government administration including, but not limited to, presidential and government telecommunication networks, defense, security and protection of legal order in the Russian Federation;



•

annulment of a frequency allocation if it results in the inability to render communications services;



•

failure in a timely requirements of the licensing authority, which commits to eliminate detected violations, including provisions that had been granted under reprimand to suspend the license.

        In addition, licenses may be terminated for various reasons by a court, including:

•

failure to remedy in a timely manner a violation that led to the suspension of the license;



•

provision of inaccurate information in documents on the basis of which a license was issued; and



•

failure to fulfill obligations undertaken in the process of a tender or auction.

        The license may also be terminated by the Federal Service for Supervision of Communications, Information Technologies and Mass Media in a number of cases, including liquidation of a license holder. A suspension or termination of a license may be appealed in court.

        Frequencies are allocated for a maximum term of ten years, which may be extended upon the application of a frequency user. Under the Federal Law on Communications, frequency allocations may be changed for purposes of state management, defense, security and protection of legal order in the Russian Federation with the license holder to be compensated for related losses. Further, frequency allocations may be suspended or terminated for a number of reasons, including failure to comply with the conditions on which the frequency was allocated.

        The following one-time license fee is payable irrespective of the number of regions covered by the license: RUB 7,500 for services involving, among other things, the use of a frequency spectrum and the lease of communication channels. The license fee for a license received through a tender or auction is determined by the terms of such tender or auction.

        Furthermore, the Federal Law on Communications provides for the establishment of a "universal services reserve fund" for the purpose of supporting communications companies operating in less developed regions of Russia through the financing, construction and maintenance of telecommunications networks in low-profit and unprofitable sectors. This reserve fund is aimed at eliminating the practice of cross-subsidies by compensating operators for certain mandatory, loss-making local services in rural and sparsely populated areas. It is funded by a levy imposed on all

115

Table of Contents

operators of public networks, including us, in the amount of 1.2% of revenues from telecommunications services less the amount of taxes paid by subscribers. The universal service fund concept has been used in some developed countries and in Eastern Europe.

        The Federal Law on Communications empowers the Russian government to determine and annually review the list of licensing requirements applicable to various communication services being licensed. The list of licensing requirements was enacted by Government Decree No. 87 dated February 18, 2005, as amended. Licenses also generally contain a number of other detailed conditions, including a date by which service must begin, technical standards and certain other terms and conditions. We have either commenced service by the applicable deadline or received an extension of the applicable deadline for all of our licenses.

Equipment Certification

        Government Decree No. 532 adopted on June 25, 2009, sets forth the types of communications equipment that is subject to mandatory certification. Communications equipment must be certified, or its compliance with the established requirements must be declared and proven in the interconnected communications network of the Russian Federation, which includes all fixed line and wireless networks open to the public. All our networks must be certified. The Federal Communications Agency issues certificates of compliance with technical requirements to equipment suppliers based on the Agency's internal review. In addition, a Presidential decree requires that licenses and equipment certifications should be obtained from the Federal Security Service to design, produce, sell, use or import encryption devices. Some commonly used digital cellular telephones are designed with encryption capabilities and must be certified by the Federal Security Service.

        Further, certain high-frequency equipment, a list of which was approved by Government Decree No. 539 dated October 12, 2004 (as amended), manufactured or used in the Russian Federation, requires special permission from the Federal Service for Supervision of Communications, Information Technologies and Mass Media. Failure to receive such certification could result in the mandatory cessation of the use of such equipment. In accordance to Government Decree No. 1252 dated November 27, 2014, the equipment can be shared by operators according to their agreement and certificate of the Federal Service for Supervision of Communications, Information Technologies and Mass Media. In accordance with the Federal Law No. 204 dated June 23, 2016, the radio frequency spectrum can be shared by operators according to their agreement. In the case of shared-use of the radio frequency spectrum for the provision of telecommunications services each operator should have proper telecommunications services license.

Competition, Interconnect and Pricing

        The Federal Law on Communications requires federal regulatory agencies to encourage competition in the provision of communication services and prohibits the abuse of a dominant position to limit competition. The Federal Law on Communications provides that telecommunications tariffs may be regulated in cases provided for by legislation. The Federal Law on Communications and Presidential Decree No. 221, enacted on February 28, 1995, as amended, on Measures for Streamlining State Regulation of Prices (Tariffs) allow for regulation of tariffs and other commercial activities of telecommunications companies that are "natural monopolies." Government Decree No. 637, dated October 24, 2005 (as amended by the Government Decree No. 941, dated September 4, 2015) authorized the FAS to set the following tariffs for the natural monopolies in the communications market, including:

•

provision of access to a local telephone network;



•

permanent use of a subscriber's line; and

116

---

Table of Contents

•

local, intra-zone and DLD calls.

        In addition, the Federal Law on Natural Monopolies No. 147 dated August 17, 1995 establishes the legal basis for federal regulation of natural monopolies, including those in the communications market, and provides for governmental control over tariffs and certain activities of the natural monopolies. The Federal Law on Natural Monopolies outlines the types of transactions for which a regulated entity must obtain prior FAS approval and establishes the general principle that regulated entities may not refuse to provide regulated services to certain types of consumers. Regulated entities are also subject to continuous reporting requirements, including submitting plans for capital investments.

        The FAS maintains a Register of Natural Monopolies whose tariffs are controlled and regulated by the state. A telecommunications operator may be included in this register upon a decision by the FAS based on analysis of the operator's activities and the market conditions.

        Our subsidiary, MGTS, was added to the Register of Natural Monopolies in 2000 and, therefore, is subject to the requirements of the Federal Law on Natural Monopolies including, inter alia, the following:

•

the FAS regulates and controls tariffs for services provided by MGTS, including installation fees, monthly subscription fees (for subscribers to the unlimited tariff plan) and local call charges (for subscribers who do not use the unlimited tariff plan);



•

MGTS must obtain prior FAS approval for any transaction involving the acquisition, disposal or lease of assets not related to the regulated activity, if the value of such assets exceeds 10% of MGTS' share capital, additional capital, retained profits and reserves;



•

MGTS is required to maintain separate accounting records for each type of activity;



•

MGTS is required to publicly disclose information on tariffs, products, material conditions of contracts with customers, capital expenditure programs and certain other information; and



•

MGTS is required to comply with Federal law No. 223-FZ dated July 18, 2011 "On Procurement of Goods, Works, Services by Certain Types of Legal Entities" while procurement of goods and services.

        It should also be noted that our subsidiary Comstar-Regions was added to the Register of Natural Monopolies in 2009, but on November 24, 2015 it was excluded therefrom and on December 5, 2015, it merged into MTS.

        In addition, companies which are found to have dominant position on relevant markets may be subject to certain FAS restrictions in conducting their business, including in relation to pricing, acquisitions, geographical expansion, and associations and agreements with competitors.On January 5, 2016, the new version of the Federal law No. 135-FZ "On protection of the competition" came into force and the regulations in relation to the register of companies holding market share excess 35% were repealed. Nowadays, dominant position should be determined regarding each case without a register. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate and are determined to have abused this position, the FAS may be entitled to regulate our subscriber tariffs and impose certain restrictions on our operations."

        The Federal Law on Communications also provides for the special regulation of telecommunications operators occupying a "substantial position," i.e., operators which together with their affiliates have, in the Russian Federation generally or in a geographically defined specific numerical zone, 25% or more of installed capacity or capacity to carry out transmission of not less than 25% of traffic. MGTS was added to the register of telecommunications operators occupying a

117

---

Table of Contents

substantial position and, therefore, is subject to the requirements of the Federal Law on Communications relating to operators occupying a substantial position in the public switched telephone networks including, inter alia, the following:

•

MGTS must develop interconnect rules and procedures in accordance with the requirements set forth by the federal government;



•

MGTS must ensure that interconnect agreements with operators who intend to interconnect to our networks are entered on the same terms and conditions as the agreements between MGTS, us and our affiliates; MGTS also cannot refuse to provide interconnect or discriminate against one operator over another;



•

MGTS must comply with the mandatory orders of the Federal Service for Supervision of Communications, Information Technologies and Mass Media issued if non-compliance with law was identified as a result of monitoring of MGTS' interconnect terms; and



•

MGTS must comply with the tariffs for interconnect and traffic transit where determined by the Federal Communications Agency.

        The Federal Law on Communications and implementation rules adopted by Government Decrees No. 161 dated March 28, 2005, and No. 627 dated October 19, 2005, also provides for government regulation of interconnect tariffs established by operators occupying a substantial position. In addition, such operators, including MGTS, are required to develop standard interconnect contracts and publish them as a public offer for all operators who intend to use such interconnect services.

        Notwithstanding the above, fixed line operators not considered to occupy a substantial position and not included in the Register of Natural Monopolies, as well as mobile operators, are free to set their own tariffs. Also see "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we or any of our mobile network operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

Calling Party Pays

        In March 2006, the Federal Law on Communications was amended to incorporate a "calling party pays" scheme effective as of July 1, 2006. Prior to the implementation of the "calling party pays" principle, subscribers of fixed line operators could initiate calls to mobile phone users free of charge. Under the current system, fixed line operators charge their subscribers for such calls and transfer a percentage of the charge to mobile operators terminating such calls. The percentage transferred to mobile operators is regulated by the Federal Service for Supervision of Communications, Information Technologies and Mass Media and is known as the settlement rate.

Communications Services rules and Mobile Number Portability

        On December 15, 2014, Government Decree No. 1342 concerning fixed and mobile services rules was adopted. This act, inter alia, has changed rules and conditions of MNP process (retaining telephone number after switching from one mobile operator to another) of certain types of legal entities and state customers. The period of switching numbers for mentioned subscribers was decreased and the procedure was simplified.

        Introduction of renewed procedure on MNP in respect of particular legal entities and state customers affects the mobile services market in Russia and leads to intensification of competition.

Anti-terror law

        The Federal Law No. 374 dated July 6, 2016, amended some legislative acts and established additional measures to counter terrorism and to maintain public safety.

        In accordance with the abovementioned amendments to the Federal Law on Communications (coming into force in July, 2018) the telecommunications operators will have to store and to provide to the authorities upon request the information on the facts of receiving, transmitting, delivering and (or) processing of voice information, text messages, images, sounds, video, or other communications by their subscribers, as well as relevant messages themselves.

        The implementation of these amendments may have a material effect on telecommunications operators' financials and performance (see also "Item 3. Key Information—D. Risk Factors").

Subscribers identification

        The Federal Law No 245 dated July 29, 2017, amended the Federal Law on Communication to prevent the conclusion of the contract on the provision of services of mobile communications without proper identification of the subscriber (user) of communication services.

        These amendments (coming into force in June, 2018) may have material effect on telecommunications operators because they will be required to implement measures to organize of interaction with state resources for verification of information about subscribers.

Regulation in Ukraine

Regulatory Authorities

        Administration of State Service on Special Communications and Information Protection of Ukraine.    This body is responsible mainly for establishing and overseeing technical policies and standards in the sphere of telecommunications. Previously these functions were carried out by the State Communications Administration.

        National Commission for the State Regulation of Communications and Informatization (the "NCCIR").    The functions of the NCCIR were formerly carried out by the NCRC (National Commission for Communications Regulation of Ukraine). Established by a Decree of the President of Ukraine in August 2004, the NCRC was vested with the powers of the central regulatory body in the sphere of telecommunications on January 1, 2005 pursuant to the Telecommunications Law described below. It consisted of seven members and a chairperson. The NCRC commenced its activity in April 2005 when the chairperson and its members were appointed as required by the Telecommunications Law.

        The NCRC has been responsible for issuing licenses for telecommunications services and use of radio frequencies commencing January 1, 2005, as well as various other responsibilities of the SCA from that date. According to the amendments to the Telecommunications Law introduced in July 2011, the NCRC was replaced in August 2011 with the NCCIR, which now consists of five members and a chairperson. The NCCIR is currently responsible for issuing licenses for telecommunications services and use of radio frequencies, and other functions of former NCRC.

        Ukrainian State Center for Radio Frequencies (the "UCRF").    While licenses for radio frequencies for wireless communications are issued by the NCCIR, SCRF is the authority responsible for all technical issues related to the use of radio frequency resources and, in such proxy, is also involved in the issuance of radio frequency licenses. In particular, the SCRF determines frequency availability and technical aspects of frequency allocation, as well as provides the NCCIR with an expert opinion in relation to each application for radio frequency. The UCRF also independently issues individual

119

Table of Contents

permissions for the use of radio electronic and radio emitting equipment, its development, import, sale and purchase, and maintains a data base of IMEI codes of mobile telephones.

        Antimonopoly Committee of Ukraine (the "AMC") is charged with the administration of competition legislation and the protection and regulation of economic competition in Ukraine, including economic competition among industry participants in the telecommunications sector.

Legislation

        The principal legislation regulating the telecommunications industry consists of the Law on Telecommunications dated November 18, 2003, (the "Telecommunications Law"), and the Radio Frequencies Law dated June 1, 2000, (the "Radio Frequencies Law").

        The Telecommunications Law provides for, among other things, equal rights for private entrepreneurs and legal entities to offer telecommunications services, fair competition and freedom of pricing. The Telecommunications Law also sets forth the legal, economic and organizational framework for the operation of companies, associations and government bodies forming part of the telecommunications networks. The licensing of telecommunications services, the requirements for equipment certification and liability for violations of Ukrainian legislation on telecommunications are also determined by this legislation. The Telecommunications Law also governs the relations between the state and local governmental bodies, telecommunications operators and users of telecommunications services and radio frequencies.

        The Telecommunications Law addresses various areas of telecommunications services in Ukraine, including numbering requirements, tariff and settlement regulations, interconnect, public telecommunications services, market access rules and licensing issuance and renewal. The Telecommunications Law also significantly expands the definition of the telecommunications services market, including in its scope Internet Protocol telecommunications, transmission of data and facsimile communications.

        The Telecommunications Law also restructured the regulatory bodies governing the area of telecommunications. It provided for the creation of the NCRC, which, between January 1, 2005, and July 5, 2011, had been responsible for many of the functions formerly handled by the SCA. In August 2011, the NCRC was replaced with the NCCIR, which is authorized, inter alia, to issue regulations for telecommunications services, issue telecommunications licenses to operators and providers, issue frequency licenses, request information from operators, providers and authorities, impose administrative penalties and maintain the register of the operators and providers. The NCCIR is also authorized to conduct hearings and to resolve disputes among operators concerning the interconnect of telecommunications networks.

        In July 2010, the Telecommunications Law was amended with provisions on mobile number portability and national roaming obligations. In April 2013 the NCCIR (formerly NCRC) adopted regulations which allow subscribers to retain their mobile telephone numbers when switching from one mobile telecommunications operator to another.

        On August 25, 2011, the NCCIR enacted national roaming regulations. Accordingly, telecommunications operators were permitted to conclude agreements on national roaming and prescribed to provide this service as described in the regulations (e.g., must inform users on roaming prices and maintain quality of service on the same level for own subscribers and subscribers of operators with whom roaming agreements are signed). Foreign investments in Ukrainian telecommunications operators are not limited; however, in order to provide telecommunications services in Ukraine an entity must be located on the territory of Ukraine and registered in accordance with Ukrainian legislation.

        The Radio Frequencies Law sets forth comprehensive rules regarding the allocation, assignment, interrelation and use of radio frequencies, the licensing of the users of radio frequencies and other relevant issues.

Licensing of Telecommunications Services and Radio Frequency Allocation

        Commencing January 1, 2005, the NCCIR (formerly NCRC) has assumed responsibility for issuing telecommunications licenses and frequency licenses pursuant to the Telecommunications Law and the 2004 amendments to the Radio Frequencies Law. Licenses are issued for the following types of telecommunications services:

•

fixed-line telephone communications services (local, intercity, international);



•

fixed-wireless telephone communications services (local, intercity, international);



•

mobile telephone communications services; and



•

technical maintenance and exploitation of telecommunications networks.

        Other telecommunications services do not require licenses.

        An operator that is granted a telecommunications license may not commence the provision of wireless telecommunications services until it receives a frequency license. The issuance of a frequency license is, in turn, subject to the availability of radio frequencies in the respective regions of Ukraine. Frequency licenses are issued for specific bandwidths within certain frequency spectrums in specific regions. The GSM and UMTS spectrum is presently considered to be the most commercially attractive for telecommunications operators. It is currently deemed to be virtually impossible to obtain a license for GSM frequencies in major Ukrainian cities because most of the GSM radio frequencies in such cities are already licensed to the existing GSM operators, including us. UMTS radio frequencies are currently allocated for special users, in particular, the Ministry of Defense.

        Under applicable legislation, licenses for telecommunications services may be issued and renewed for periods of not less than 5 years, with the actual period generally ranging from 10 to 15 years. Renewal of a license is made by an application submitted to the NCCIR at least four months prior to the expiration of the license term. NCCIR officials have broad discretion with respect to both the issuance and the renewal of licenses. The Telecommunications Law further provides that the NCCIR must grant licenses on a first come-first served basis within 30 days from submission of an application. If resources are limited or consumer interests so require, the NCCIR may adopt a decision to limit the number of licenses. In this event, the law requires that such decision is made public along with the rationale and that the licenses be allocated through a tender.

        In accordance with the Radio Frequencies Law, the NCCIR issues a frequency license concurrently with the issuance of a telecommunications license for the type of services requiring use of radio frequency resources. A telecommunications operator that has the respective telecommunications license may apply for licenses for additional radio frequency bands. Frequency licenses may not be issued for a period shorter than the term of the relevant telecommunications license.

        Under applicable legislation, a public tender or an auction for a radio frequency license must be held by the NCCIR if demand for radio frequency resources exceeds available resources. Radio frequency licenses issued on the basis of a public tender or an auction for the same type of radio technology must include identical conditions regarding the radio frequency bands and development period. Telecommunications operators are allowed to apply to the NCCIR for redistribution of the radio frequency resources previously allocated to them.

Table of Contents

        Applicable legislation prohibits the transfer of a license by the licensee, including by means of assignment or pledge of a license as collateral, and agreements regarding the provision of telecommunications services must be executed and performed by the actual licensee.

        Licenses generally contain a number of detailed conditions, including the date by which service must be commenced, terms of network deployment and territory coverage, the requirement to use only certified equipment, the technical standards which must be considered and the requirement to comply with all environmental regulations. Frequency licenses issued after January 1, 2005 also contain the date by which the radio frequency resources must be fully utilized.

        Telecommunications operators' activities are subject to strict regulations, especially regarding electromagnetic compatibility; construction and technical maintenance of a telecommunications network must be carried out in accordance with specific regulations applicable in Ukraine. Telecommunications operators must submit periodic reports to the NCCIR on the amount and quality of services provided under the telecommunications license. We believe that we are in compliance with the applicable laws and regulations related to our Ukrainian licenses.

        Some licenses also provide that services for persons entitled to certain social benefits must be provided at or below certain minimum thresholds established by Ukrainian legislation in effect at that time.

        If the terms of a license are not fulfilled or the service provider violates legislation, the license may be suspended or terminated. Both telecommunications services licenses and radio frequency licenses may be terminated for various reasons, including:

•

provision of inaccurate information in the application for a license;



•

repeated refusal to allow the representatives of the NCCIR to make inspections;



•

failure to remedy in a timely manner the circumstances which resulted in a violation of the license terms;



•

repeated violation of the license terms;



•

transfer or assignment of the license to a third party; and



•

other grounds set forth by Ukrainian laws.

        Radio frequency licenses may also be terminated for the following reasons:

•

failure to commence using radio frequency resources within the time period specified in the license;



•

termination of use of radio frequency resources specified in the license for more than one year;



•

failure to use radio frequency resources to the full extent within the time period specified in the license; and



•

failure to pay monthly fees for the use of allocated radio frequencies for six months or more.

        Decisions of the NCCIR with respect to the termination of licenses may be appealed to a court.

        MTS' Ukraine license to construct and maintain the telecommunication network and provide services using such network was due to expire on December 3, 2013. In October 2013, MTS Ukraine submitted an application to the NCCIR requesting the renewal of the license. On October 15, 2013, the NCCIR refused to renew the license and recommended that MTS Ukraine receive a new license to provide operations in the telecommunications sphere. On October 21, 2013, MTS Ukraine filed a lawsuit against the NCCIR with a demand to renew the license. On November 19, 2013, a court decision was issued in favour of MTS Ukraine. The decision obliged the NCCIR to renew the license.

The NCCIR appealed against the court decision. On January 15, 2014, the court of appeal issued a judgement in which the court refused to sustain the NCCIR appeal. On January 28, 2014, the NCCIR renewed MTS Ukraine license until December, 2018. On January 27, 2014, the NCCIR filed an appeal against the court of appeals' order which was denied by the Court. The cassation procedure was started by Court of Cassation. According to decision of the Highest Administrative Court dated January 22, 2015, the satisfaction of claim dated November 19, 2013 in favor of MTS Ukraine was denied making the resolution of January 28, 2014 to prolong the license for MTS Ukraine illegitimate. In 2016, the case was sent to a new trail. The first instance Court (03/25/2016) and Appeal Court (05/31/2016) refused in satisfaction of the MTS Ukraine demand to prolong the license for MTS Ukraine. On the base of the resolution of the Superior Court of Ukraine from the July 11, 2016, cassation procedure is opened. The case is in progress.

        At the same time MTS Ukraine has bought a new license for providing all available mobile services in 2G and 3G networks and NCCIR issued a license for MTS Ukraine as of January 27, 2015, which is valid until 2030.

        In accordance with the terms of obtaining a license for 3G frequency, MTS Ukraine has signed conversion agreements with special users of radio frequency resource. Within an 18-month period MTS plans to expand its 3G network in all regional centers of Ukraine. Currently, MTS Ukraine complies with all license requirements and makes all necessary payments under the license.

4G/LTE

        Under the instruction of the President of Ukraine on the introduction of 4G network, the Cabinet of Ministers adopted a decree "On approval of the action plan for introduction of mobile communication of the fourth generation." The decree establishes a tender process for 4G frequency in the second half of 2017. Which primarily this requires carrying out a research and analysis of the existing radio frequency resource. This research was assigned to foreign consultants with payment to be imposed on telecommunications operators. The foreign consultant was chosen—Analyses Mason LTD (London, UK). In accordance with recommendations of research NCCIR has prepared amendments to legislation on management of the radio frequency resource and has announced two tenders on frequencies in diapasons for 4G/LTE—2600 MHz and 1800 MHz. The process of licensing 4G/LTE was finalized in March 2018. In January and March 2018, VF Ukraine secured a 4G licenses in the 2510-2520 / 2630-2640 and 1780-1785 / 1875-1880 MHz bands as the result of a national auction. The first 4G launch in Ukraine's largest cities took place in March 2018.

Equipment Certification

        For installation on a telecommunications network either the manufacturer or the vendor must provide the operator with a document of confirmation to the normative documents compliance and documentary confirmation of inclusion in the registry of technical equipment that can be used in the telecommunication network. According to the Law of Ukraine "On Telecommunications," this register is maintained by the Administration of the State Service on Special Communications and Information Protection of Ukraine.

        The Radio Frequencies Law provides that users of radio frequency resources must obtain permits for the operation of radio-electronic and radio-emitting equipment, except for equipment used on a permit-free basis in accordance with this law. In order to obtain such operation permit, a company is required to file an application with the UCRF. The Radio Frequencies Law also requires producers and importers of radio-electronic and radio-emitting equipment to be used on the territory of Ukraine to register such equipment in the special list which NCCIR maintains.

Competition

        The Telecommunications Law provides that one of the purposes of the licensing of telecommunications services is to encourage competition and de-monopolization in the telecommunications industry.

        Ukrainian antimonopoly legislation prohibits a company operating in Ukraine from abusing its dominant position in its market to gain, inter alia, an unfair or anti-competitive advantage in the provision of its services or products. A legal entity is deemed to be in a dominant position if such entity has no competitor in the market or is not subject to substantial competition due to restricted access or entry barriers for other business entities. Further, Ukrainian antimonopoly legislation provides that a company shall be deemed dominant if its market share in the respective product market exceeds 35% unless such company proves that it faces significant competition in the respective product market. A telecommunications operators which are found by the AMC as having a dominant position in the markethave to use the rates for national and international interconnect, which are established by the NCCIR.

        According to AC&M-Consulting, Vodafone Ukraine had a 36% market share of the wireless communications market in Ukraine as of December 31, 2017.

        Please see also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—A finding by the AMC that we have acted in contravention of antimonopoly legislation could have a material adverse effect on our business, financial condition and results of operations."

Tariffs

        According to the Ukrainian laws, NCCIR regulates the following tariffs:

•

maximum tariffs on public telecommunication services;



•

tariffs on leasing of communication channels for operators with dominant market position;



•

maximum tariffs on leasing channels of cable duct system;



•

calculation rates for services of crossing traffic to the telecommunication networks of telecommunications operators with substantial market advantage on the markets of certain telecommunication services.

        Under the Law of Ukraine on Telecommunications the Cabinet of Ministers of Ukraine is not authorized to regulate prices for telecommunication services.

        Although there are no additional regulations limiting level of maximum tariffs on wireless telecommunications services, if the Antimonopoly Committee believes competition laws are violated, it can assert that tariffs unfair and injurious to market competition. In such cases, the AMC may, inter alia, request the telecommunications operator whom AMC considers as one violating the laws to remedy the situation, in particular, to amend its tariff scheme, and impose fines on the company for an violation.

        Subject to the above, wireless operators are free to set tariffs at levels they consider appropriate.

Interconnect Arrangements and Telephone Numbering Capacity

        In Ukraine, mobile operators are allocated numbering capacity by the NCCIR (National Commission for the State Regulation of Communications and Informatization). We believe that sufficient numbering capacity has been allocated to us in Ukraine for the development of our mobile network. We also believe that we have been allocated sufficient fixed line numbering capacity with respect to the cities in which we are developing our fixed line networks. We plan to develop fixed line

124

Table of Contents

network in every administrative district of Ukraine. For this purpose we plan to purchase additional numbering capacity of 1000 numbers in one city.

        Interconnect activity is regulated by the NCCIR. Operators may provide offers for interconnect to the NCCIR, and the NCCIR is required to publish on an annual or regular basis a catalog of such offers. Operators with a dominant position on the market and operators having significant market power (SMP-operators) are obliged to submit interconnect offers to the NCCIR for each catalog.

        Interconnect is made pursuant to interconnect agreements between network operators as prescribed by the regulatory authorities. Such agreements are required under the law to contain certain provisions. An operator with a dominant position, as well as SMP-operator, cannot refuse an offer to conclude an interconnect agreement with another operator, if the offeror has offered points of interconnect that were previously published by the NCCIR in the catalog of interconnect proposals.

        The NCCIR is authorized to conduct hearings and to resolve disputes among operators concerning the interconnection of telecommunications networks. Decisions of the NCCIR are binding upon the parties in the dispute but a party to the dispute may appeal such a decision in court.

        In May 2009, the AMC issued a finding that eight mobile operators, including MTS Ukraine and its closest competitors, have a dominant position in relation to the market for interconnecting to each of their respective networks. In February 2010, the NCRC established regulated interconnect fees for termination of calls on the networks of operators that have a dominant position. See "—Competition."

        In October 2011, the NCCIR defined all of operators, including MTS Ukraine, that have operated in the Ukrainian market in the period from 2009 through 2010 as having significant market power for termination traffic on their fixed and mobile networks. Effective 1 January 2012, the NCCIR regulates the interconnection rates for all SMP fixed and mobile operators, including MTS Ukraine. The interconnection rates charged by long-distance operators are set up equal to rates charged by mobile operators.

        The NCCIR regularly analyses the telecommunication market to determine operators with significant market power in this market (SMP-operators). In October 2015 the NCCIR published the results of the latest market analysis according to which 276 fixed and all six mobile operators, including MTS Ukraine, were defined as SMP-operators. On August 30, 2016 the NCCIR adopted the next regulatory act which establishes new interconnect rates for termination traffic on the networks of SMP-operators, effective since January 1, 2017. As a result that the interconnect rates were decreased from UAH 0.23 (RUB 0.472012*) to UAH 0.15 (RUB 0.307834*) for long- distance and mobile operators. Please see also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we cannot interconnect cost-effectively with other telecommunications operators, we may be unable to provide services at competitive prices, which may diminish our market share and result in a loss of revenues and margins" for details of NCCIR' s plans to substantially lower interconnect rates for the termination of traffic.

        We also lease buildings in Moscow for similar purposes, including marketing and sales and other service centers. In addition, through our subsidiary MGTS, we own approximately 133 buildings located throughout Moscow, which serve as sales and customer service offices, house MGTS' telecommunication equipment and are leased to third parties. We also own office buildings in some of our regional license areas and in Ukraine, and we lease office space on an as- needed basis. We believe that our properties are adequate for our current needs and additional space is available to us if and when it is needed.

        The primary elements of our network are base stations, base station controllers, transcoders and mobile switching centers. Base stations occupy sites leased at selected locations in all the areas in which we provide network coverage. GSM, 3G and 4G technologies are based on an "open architecture," which means that equipment from one supplier can be combined with that of another supplier to expand the network. Thus, there are no technical limitations to using equipment from different suppliers.

In particular, we refer you to the risks discussed in "Item 3. Key Information—D. Risk Factors" for information regarding governmental, economic, fiscal, monetary or political policies or factors that could materially adversely affect our operations or your investment in our shares and ADSs. In addition, this section contains forward-looking statements that involve risk and uncertainties. Our actual results may differ materially from those discussed in forward-looking statements as a result of various factors, including those described under "Item 3. Key Information—D. Risk Factors" and "Cautionary Statement Regarding Forward-Looking Statements." Our reporting currency is the Russian ruble and our consolidated financial statements have been prepared in accordance with IFRS.

A.  Operating Results

Overview

        We are a leading telecommunications provider in Russia and the CIS, providing a wide range of mobile and fixed line voice, data telecommunications and digital services, including transmission,

144

Table of Contents

broadband, pay-TV, various value-added services as well as integratrion services and selling equipment and accessories. According to AC&M-Consulting, we are the largest mobile operator in Russia and the second largest in Ukraine in terms of mobile subscribers. We are also the largest operator in Armenia in terms of mobile subscribers, according to our estimates. As of December 31, 2017, we had a mobile subscriber base of approximately 101.2 million.

        Our revenues for the year ended December 31, 2017 totaled to RUB 442,911 million, an increase of 1.7% year-over-year. Overall, the Group's performance in 2017 was largely driven by Russia where the increase in revenues was attributable to the natural growth in data consumption and better monetization through the cancellation of unlimited data plans. Our operating income for the year ended December 31, 2017 increased by 9.6% to RUB 96,100 million due to strong service revenue in Russia as well as roaming cost optimisation. Our profit for the year ended December 31, 2017 increased by 16.8% to RUB 56,590 million generally repeating our operating income dynamics.

        Our revenues for the year ended December 31, 2016 increased by 2.1% to RUB 435,692 million due to sustained growth in data usage throughout key markets and increased handset sales in Russia. Our operating income for the year ended December 31, 2016 decreased by 6.7% to RUB 87,669 million due to additional expenses in retail as well as generally increased costs in Russia due to macroeconomic pressure. Our profit for the year ended December 31, 2016 increased slightly by 2.1% to RUB 48,450 million generally repeating our operating income dynamics. Our profit was also affected by an increase in finance costs related to repurchase of our Eurobonds due in 2020 and decreased finance income. Those effects were partially offset by the strengthening of the ruble coupled with improved performance of our non-operating affiliates (mainly MTS Bank).

        Significant funds are required to support the growth of our subscriber base, primarily for increasing network capacity, maintaining and modernizing our mobile and fixed line networks, developing our network in the regions and continuing the build-out of our LTE, 3G and broadband Internet networks.

        Our cash outlays for capital expenditures for the years ended December 31, 2015, 2016 and 2017 were RUB 106,537, RUB 86,149 million and RUB 76,431 million, respectively.

        We have financed our cash requirements through our operating cash flows and borrowings. Net cash provided by operating activities for the years ended December 31, 2015, 2016 and 2017 was RUB 144,088 million, RUB 130,565 million and RUB 144,640 million, respectively.

        Our borrowings consist of notes and bank loans. Our notes comprise of U.S. dollar and ruble denominated notes. As of December 31, 2017 and December 31, 2016 U.S. dollar denominated notes totaled to RUB 43.8 billion and RUB 46.8 billion, and ruble denominated notes amounted to RUB 65.0 billion and RUB 31.4 billion, respectively. Our bank loans consist of U.S. dollar and ruble-denominated borrowings totaling approximately RUB 182.9 billion as of December 31, 2017 and RUB 195.1 billion as of December 31, 2016.

        We repaid approximately 90.2 RUB and RUB 45.1 billion of indebtedness in 2016 and 2017, respectively. As of December 31, 2017, the total amount available to us under our credit facilities amounted to RUB 36.0 billion. We had total indebtedness of approximately RUB 303.6 billion as of December 31, 2017, including capital lease obligations, compared to approximately RUB 284.3 billion as of December 31, 2016.

        Our total finance costs for the years ended December 31 2017, 2016 and 2015 were RUB 26,064 million , RUB 27,136 million and RUB 26,422 million, net of amounts of interest capitalized, respectively. See Note 15 to our audited consolidated financial statements for a description of our indebtedness.

        Our reporting currency is Russian rubles. Our and our subsidiaries' functional currencies are the ruble in Russia, the hryvnia in Ukraine, the manat in Turkmenistan, the dram in Armenia and the som in Uzbekistan (before UMS (as difined below) was deconsolidated). See "—Certain Factors Affecting our Financial Position and Results of Operations—Currency fluctuations" and "Item 11. Quantitative and Qualitative Disclosures about Market Risk—Foreign Currency Risk."

Segments

        Management (chief operating decision maker) analyzes and reviews results of the Company's operating segments separately based on the nature of products and services, regulatory environments and geographic areas. MTS Group's management evaluates the segments' performance based on revenue and operating profit, excluding depreciation and amortization. Management does not analyze assets or liabilities by reportable segments.

        The Group identified the following reportable segments:

        Russia convergent:    represents the results of mobile and fixed line operations, which encompasses services rendered to customers across regions of Russia, including voice and data services, transmission, broadband, pay-TV and various value-added services and retail operations.

        Moscow fixed line:    represents the results of fixed line operations carried out in Moscow by the Group's subsidiary MGTS. MGTS is the only licensed public switched telephone network ("PSTN") operator in Moscow and is considered a natural monopoly under Russian antimonopoly regulations. Consequently, substantial part of services provided by MGTS are subject to governmental regulation.

        Ukraine:    represents the results of mobile and fixed line operations carried out across multiple regions of Ukraine.

        The "Other" category does not constitute a reportable segment. It includes the results of a number of other operating segments that do not meet the quantitative thresholds for separate reporting, such as Turkmenistan, Armenia, System Integrator, Satellite TV, Navigation Information Systems, Metro-Telecom, Stream LLC, NVision Czech Republic, Litebox, eSports, Belarus and headquarters.

        In 2017, management has started internally assess Russia convergent and NVision Czech Republic, Stream LLC, Navigation Information Systems and Metro-Telecom separately in order to monitor the results and make funding decisions on this basis, and thus has presented them separately. Related financial information was, retrospectively, restated.

        The results of operations of UMS are reported as discontinued operations in the accompanying consolidated statements of profit or loss. The segment reporting for the year ended December 31, 2015 was restated accordingly. The consolidated statement of financial position is not required to be retrospectively restated with respect to discontinued operations and therefore as of December 31, 2015 statement of financial position captions in the "Other" category of the following presentation include UMS.

        Total revenues of our segments for the years ended December 31, 2015, 2016 and 2017 were as follows:

Certain Operating Data

        Below we provide certain operating data not included in our financial statements that we believe is useful for evaluating our business and results. The data focuses primarily on our mobile operations, particularly in Russia and Ukraine, which comprise the most significant share of our revenue in the periods presented, and is among the information routinely reviewed by our management as part of their regular evaluation of our performance.

Mobile Subscriber Data

        The following table shows our mobile subscribers by country as of the dates indicated:

        We had approximately 78.3 million subscribers in Russia as of December 31, 2017, and a leading 31% market share of total mobile cellular subscribers in Russia, according to AC&M-Consulting. Overall penetration in Russia was at approximately 179%, according to AC&M-Consulting. We had approximately 20.8 million subscribers in Ukraine as of December 31, 2017 and, according to AC&M-Consulting, a 36% market share of total mobile cellular subscribers in Ukraine. In addition, as of December 31, 2017, we had approximately 2.1 million subscribers in Armenia, representing 59% market share, according to our estimates. From September 29, 2017 MTS stopped providing communication services in Turkmenistan due to the actions of the state-owned telecommunication company Turkmentelekom, which resulted in disconnection of international and long-distance zonal

communication services and internet access. At that moment our subscriber base amounted 1.7 million subscribers or 30% of Turkmenistan market according to our estimates.

        For a description of our fixed line subscriber base, see "Item 4. Information on Our Company—B. Business Overview—Fixed Line Services."

Revenues

        Our principal sources of revenue are:

•

mobile service revenues, which include usage and interconnect fees, value-added services fees, monthly subscription fees, roaming fees and connection fees;



•

fixed service revenues from individual and corporate subscribers, which include monthly subscription fees, traffic charges, connection fees, revenues from broadband Internet connection and data transmission services, revenues from pay-TV and from sales of end-user telecommunications equipment. Fixed service revenues also include revenues received from operators, which comprise revenues from the renting out of channels and traffic charges and revenues from the renting out of telecommunications infrastructure;



•

revenues from sales of handsets, accessories and other goods; and



•

integration services, including the resale of software products.

        Our mobile tariffs in Russia and Ukraine are not regulated by any organization or governmental authority. The interconnect fees we charge to other operators for terminating calls interconnecting to our mobile network are not regulated in Russia, but are regulated in Ukraine. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—Changes in the governmental regulation of SMP operators in Ukraine could adversely affect our results of operations," "—If we are found to have a dominant position in the markets where we operate and are determined to have abused this position, the FAS may be entitled to regulate our subscriber tariffs and impose certain restrictions on our operations" and "—If we or any of our mobile operator subsidiaries operating in Russia are identified as an operator occupying a "substantial position," the regulator may reduce our interconnect tariffs which, in turn, may have a material adverse effect on our financial condition and results of operations."

        Certain of our fixed service tariffs are regulated, including tariffs charged by Moscow incumbent operator MGTS for installation fees, monthly subscription fees and local call charges, as well as interconnect and traffic transit tariffs. The interconnect tariffs charged by us are also regulated by the Federal Agency on Communications.

Service revenues

        Subscription, voice and data revenues primarily include monthly fees paid by our users of tariff plans which contain fixed volume of services such as minutes of usage, sms, internet traffic and other services. The over-the-limit consumption of services are charged to our subscribers depending on a tariff plan. Subscription, voice and data revenues as a percentage of our total revenues were 56.5% in 2015, 56.2% in 2016 and 56.3% in 2017. We expect subscription, voice and data revenues as a percentage of our total operating revenue to remain stable in 2018.

        Interconnect fees, which are fees for connecting users of other operators' fixed line and wireless networks to our network, comprised 11.6% in 2015, 11.4% and 11.0% of our total revenues in 2016 and 2017, respectively. In absolute terms, interconnect fees remained relatively stable and we expect it to remain stable in 2018.

Table of Contents

        Roaming fees for our own subscribers include amounts charged to our subscribers while traveling out of our service area. Roaming fees for own subscribers as a percentage of our total revenues represented 6.9% in 2015, 5.6% in 2016 and 5.3% in 2017. We expect that our roaming fees will decrease slightly as a percentage of our total operating revenue, due to individually insignificant changes in the types of revenue

        Fixed service revenues which consist primarily of fixed line telephony services, broadband internet and pay-TV services, comprised 13.4%, 13.0% and 12.7% of our total revenues in 2015, 2016 and 2017, respectively. In absolute terms, we expect an increase in the number of internet and TV users to stimulate further growth of fixed service revenues due to consequent improvement in quality and uptake of services provided.

        Other sources of revenue comprised less than 5% of our service revenues.

Sales of goods

        Sales of goods primary consist of the sale of handsets and accessories and sales of software products and as a percentage of total revenue comprised 9.5% in 2015, 11.3% in 2016 and 11.8% in 2017. The increase in 2017 as compared to 2016 is not significant. The increase in 2016 as compared to 2015 is attributable to the acquisition of NVision Group which regularly resale software products. We expect that sales of goods will remain stable as a percentage of total revenue, as smartphones and devices sales support the usage of our voice and data tariff plans. We do not subsidize handset sales in Russia. In Ukraine, we subsidize handsets for some of our contract subscribers as well as modems for GSM and CDMA users. See "—Cost of goods" below.

Cost of Services

        Interconnect and line rental.    Interconnect and line rental charges include charges payable to other operators for access to, and use of their networks, which are necessary in the course of providing service to our subscribers. Interconnect charges as a percentage of our total revenues represented 11.7% in 2015, 11.1% in 2016 and 10.6% in 2017. Line rental charges as a percentage of our total revenues represented 1.7% in 2015, 1.7% in 2016 and 1.6% in 2017.

        We expect that interconnect expenses payable by us to other operators for termination of traffic generated by our subscribers will slightly increase. Primarily, this increase will likely be attributable to the growth in the volume of traffic resulting from our efforts to encourage greater usage through the introduction of new services, which may be supported by marketing campaigns.

        We expect line rental costs to decrease due to the adoption of new accounting standard IFRS 16 "Leases" from January 1, 2018. (Please, see Note 2 to our Consolidated financial statements for 2017).

        Roaming expenses.    Roaming expenses consist of amounts charged by other cellular operators under agreements for roaming services provided to our subscribers while outside our service area. Roaming expenses as a percentage of our total revenues represented 3.2% in 2015, 3.6% in 2016 and 2.5% in 2017. The decrease of roaming expenses as a percentage of our total revenues was largely due to the impact of cost optimisation.

        Other direct costs.    Our other direct costs primary consist of:

•

production staff's salary, bonuses and social contributions;



•

rental charges for network placement;



•

network repair and maintenance;



•

electricity charges; and

•

payments for radio frequencies usage.

        Our other direct costs as a percentage of our total revenues represented 3.3% in 2015, 3.7% in 2016 and 3.8% in 2017. The slight increase is mainly attributable to rise of the salary and social contributions expenses resulting from higher number of employees (including those retained through business combinations). In addition electricity and rental charges for placement of technical facilities grew as a result of inflation and increasing number of sites rented. Other direct costs as a percentage of revenue are expected to increase over time as a result of inflation.

Cost of goods

        This type of expense includes primarily the cost of handsets and accessories sold to subscribers, the cost of SIM cards provided to our customers, the cost of software products sold and inventory obsolescence provision. Cost of handsets, accessories sold and SIM cards provided to customers as a percentage of our total revenues represented 8.5% in 2015, 9.4% in 2016 and 9.3% in 2017. The decrease in 2017 was not significant. The increase in 2016 was primarily attributable to the continuing growth in our handsets sales stimulated by aggressive smartphone pricing strategy aimed to counteract competitors' efforts to markedly increase their share of distribution in the market and drive further migration to higher value tariffs.

Selling, general and administrative expenses

        Our selling expenses comprise of all costs relating to the activities that do not directly increase the value of our products and services, but serve to secure sales. These costs consist primarily of:

•

expenses for advertising and promotion;



•

dealer commissions for the acquisition of new subscribers and cash collection;



•

personnel, utilities and maintenance costs incurred in the area of sales.

        Selling expenses have generally increased in prior years as subscribers number, market saturation and market competition have increased, as well as in connection with the further development of our brand and introduction of new value-added services. In 2017, 2016 and 2015, selling expenses comprised 12.0% , 12.3% and 11.8% of our total revenue, respectively. The slight decrease of selling expense in 2017 was mainly due advertising and marketing cost optimization. The increase of selling expenses in 2016 was mainly attributable to expansion of our retail network, number of opened stores increased by 25% in comparison to 2015.

        We retain some degree of flexibility to increase or decrease these expenses in any given period based on our requirements, strategy and the general economic environment. Nevertheless, we expect dealer commissions to decrease in 2018 as a result of the adoption of IFRS 15 "Revenue from contracts with customers" from January 1, 2018. (Please, see Note 2 to our Consolidated financial statements for 2017).

        For the structure of our dealer commissions in Russia and Ukraine please see "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Sales and Marketing—Sales and Distribution."

        We expect utilities and maintenance costs to decrease in 2018 as a result of the adoption of IFRS 16 "Leases" from January 1, 2018. (Please, see Note 2 to our Consolidated financial statements for 2017).

Table of Contents

        Our general and administrative expenses comprise of expenses attributable to the core administrative functions that cannot be allocated directly to the production or selling process. These consist primarily of:

•

personnel costs;



•

billing and data processing expenses;



•

taxes other than income taxes, e.g. property taxes;



•

office maintenance expenses and rental of administrative premises;



•

consulting expenses; and



•

other expenses of administrative nature.

        General and administrative expenses as a percentage of our total revenues represented 8.7% in 2015, 9.3% in 2016 and 9.4% in 2017. In 2017 the increase of general and administrative expenses was mainly attributable to the growth of bank commissions paid to support our sales on credit. The increase of general and administrative expenses in 2016 was mainly attributable to the growth in our personnel expenses and the release of provisions for VAT and custom duties recognized in 2015. General and administrative expenses as a percentage of revenue are expected to increase over time as a result of inflation.

        We expext rental of administrative premises expenses to decrease in 2018 as a result of the adoption of IFRS 16 "Leases" from January 1, 2018. (Please, see Note 2 to our Consolidated financial statements for 2017).

Sundry Operating Income/Expenses

        Our sundry operating income/expenses include:

•

operating share of associates' profit;



•

provision for investments in distressed banks (impairment charges incurred in 2015);



•

impairment for goodwill and long-lived assets;



•

other operating expenses such as allowance for doubtful accounts, gain/losses on disposal of property, plant and equipment and intangible assets as well as any gain/losses resulting from stock-taking.

        Sundry operating expenses/income as a percentage of our total revenues represented 0.6%, (0.8)% and 0.5% as of December 31, 2015, 2016 and 2017, respectively. In 2017 sundry operating expense amounted to RUB 2,311 million against operating income of RUB 3,337 in 2016. In 2017 operating expenses included impairment of non-current assets in Turkmenistan and Czech Republic in the amount of 3,204 million and RUB 571 million, respectively. The income in 2016 was mainly attributable to gain on sale of property, plant and equipment as well as compensation received from other operators for the transfer of our radio frequencies. The operating expense in the financial year 2015 included RUB 3,516 million impairement loss related to MTS Armenia goodwill.

Depreciation of Property, Network Equipment and Amortization of Intangible Assets

        Our expense for depreciation of property, network equipment and amortization of intangible assets as a percentage of our total revenues decreased to 18.0% for the year ended December 31, 2017 as compared to 18,7% of our total revenues for the year ended December 31, 2016. The decrease was attributable to the change of expected useful lifes of several groups of assets. Our expense for

151

Table of Contents

depreciation of property, network equipment and amortization of intangible assets comprised 18.2% of our total revenues for the year ended December 31, 2015.

        We expect our expense for depreciation of property, network equipment and amortization of intangible assets to remain relatively stable in 2018

Finance costs

        Our finance costs for 2017 decreased by RUB 1,072 million or 3.95% compared to 2016 and amounted to RUB 26,064 million. In 2016 we incurred additional interest expense in the amount of RUB 3,044 million related to early redemption of Eurobonds due 2020. Net of this effect, our finance costs for the financial year ended December 31, 2017 increased by RUB 1,972 million as a result of increased indebtness. Our finance costs for the year ended December 31, 2016 increased by RUB 713 million or 2.70% compared to 2015 and amounted to RUB 27,136 million. The increase was primarily attributable to the partial early redemption of our Eurobond due in 2020.

        We expect our finance costs to remain relatively stable in 2018.

Provision for Income Taxes

        Taxation on income of Russian companies is regulated by a number of laws, government decrees and implementation instructions.

        The income tax base for Russian companies is defined as income received from sales of goods and services reduced by the amount of expenses incurred in such operations with certain exceptions.

        The statutory income tax rate in Russia is 20%. The statutory income tax rate in Ukraine is 18%. The effective tax rate applicable to our consolidated group in the year ended December 31, 2017, 2016 and 2015 was 25.1%, 22.4% and 20.8%, respectively. The effective tax rate differs from the statutory rate mainly as a result of items not liable for tax purposes, earnings distribution from subsidiaries, prior period tax effects and effect of the change in fair value of derivative financial instruments.

Certain Factors Affecting our Financial Position and Results of Operations

Currency fluctuations

        A majority of our capital expenditure and a part of our liabilities and borrowings are either denominated in or tightly linked to the U.S. dollar or euro. A significant part of our financial liabilities, denominated in U.S. dollars, åxcluding trade accounts payables, is hedged through financial instruments with various banks. We conduct operations within the Russian Federation, Ukraine, Turkmenistan and Armenia, and we are therefore subject to currency fluctuations. The local currencies of these countries fluctuate significantly against the U.S. dollar and euro. As a result of the fluctuations we may incur significant currency exchange gains/losses which may adversely affect our net income.

Inflation

        Our financial position and results of operations as reflected in our audited consolidated financial statements included elsewhere in this document have been influenced by inflation.

Table of Contents

        The Russian economy has been characterized by high rates of inflation:

        The Ukrainian economy has been characterized by high rates of inflation:

        Inflation rate in Armenia in 2017 was estimated at 4%.

        We expect inflation-driven increases in costs to put pressure on our margins. While we could seek to raise our tariffs to compensate for such increase in costs, competitive pressures may not permit increases that are sufficient to preserve operating margins. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Inflation could increase our costs and adversely affect our results of operations."

Acquisitions

        Our results of operations for the periods presented are significantly affected by acquisitions.

Revenues and cost of services and cost of goods

        Consolidated revenues for the year ended December 31, 2017, increased by RUB 7,219 million, or 1.7%, to RUB 442,911 million from RUB 435,692 million for the year ended December 31, 2016. The principal reason for the growth was the large increase in the usage of voice and data tariffs by our subscribers (by RUB 5,387 million), which was mainly attributable to the increase in mobile internet penetration, an increase in usage of smartphones by our subscribers, active 3G and LTE network expansion and the consequent improvement of the quality and uptake of value-added services. The increase of our consolidated revenues for the year ended December 31, 2017 was also supported by the growth in revenues from sales of handsets and accessories by RUB 1,496 million and by the increase of revenues from sales of software products by RUB 1,475 million. The increase in sales of handsets and accessories by RUB 1,469 million resulted from active marketing initiatives and smartphones' penetration. The increase in sales of software products by RUB 1,475 million was attributable to the agreements with newly acquired customers.

        The decrease of our revenues from roaming fees of own subscribers by RUB 800 million in the year ended December 31, 2017 is attributable to depreciation of Ukrainian hryvnia against russian ruble and promotion of tariff plans with reduced prices, which include fixed amount of minutes in roaming.

        Consolidated cost of services and cost of goods for the year ended December 31, 2017 decreased by RUB 6,330 million and amounted to RUB 169,402 million as compared to RUB 175,732 million for the year ended December 31, 2016 and comprised 38.2% and 40.3% as a percentage of consolidated revenues for the year ended December 31, 2017 and 2016, respectively. The decrease was mainly attributable to the optimization of roaming and interconnect expenses which declined by RUB 6,157 million and depreciation of Ukrainian hryvnia against Russian ruble.

        Russia convergent revenues for the year ended December 31, 2017, increased by 3.1% to RUB 370,982 million from RUB 359,905 million for the year ended December 31, 2016. The increase in Russia convergent revenues in the year ended December 31, 2017, was primarily due to the growth of revenues from voice and data tariffs by RUB 7,102 million, revenues from sales of handsets and accessories by RUB 1,598 million, revenues from handsets customization and commissions by RUB 1,168 million and interconnect revenues by RUB 992 million.

The increase in revenues from handsets customization and commissions by RUB 1,168 million was supported by the growth in handsets sales. Increase in interconnect revenues by RUB 992 million was driven by the growth in volume of traffic.

        Russia convergent cost of services and cost of goods for the year ended December 31, 2017, decreased by 3.6% to RUB 144,230 million from RUB 149,687 million for the year ended December 31, 2016. The decrease of Russia convergent cost of services and cost of goods was mainly attributable to the decline of roaming expenses by RUB 3,461 million, interconnect expenses by RUB 865 million and line rental by RUB 255 million. The decrease was also supported by the decline in cost of handsets and accessories by RUB 1,595 million due to the shift in the structure of hansets sales in favour of higher margin products.

        Moscow fixed line revenues for the year ended December 31, 2017, slightly decreased and amounted to RUB 39,033 million as compared to RUB 39,667 million. The principal reason for the decline was a decrease in number of users of fixed line voice services.

The principal reason for the growth of our consolidated revenues for the year ended December 31, 2016, was the large increase in the usage of voice and data tariffs by our subscribers (by RUB 4,811 million), which was mainly attributable to the increase in mobile internet penetration, an increase in usage of smartphones by our subscribers, active 3G and LTE network expansion and the consequent improvement of the quality and uptake of value-added services. The increase of our consolidated revenues for the year ended December 31, 2016 was also supported by the growth in revenues from sales of handsets and accessories by RUB 5,023 million and by the increase of revenues from sales of software products by RUB 3,718 million. The increase in sales of handsets and accessories by RUB 5,023 million resulted from active marketing initiatives and continued expansion of our retail operations. The increase in sales of software products is attributable to the acquisition of NVision group at the end of 2015.

        The decrease of our revenues from roaming fees of own subscribers by RUB 5,262 million in the year ended December 31, 2016 is attributable to promotion of tariff plans with reduced price per minute and overall decrease of consumption due to adverse changes in macroeconomic situation in Russia and Ukraine. Our consolidated mobile subscriber base increased and amounted to 104.6 million as of December 31, 2016 as compared to 101.4 million as of December 31, 2015.

The cost of handsets and accessories grew as percentage of consolidated revenues by 1.0% as a result of promoting sales of smartphones and aggressive pricing policy aimed to boost smartphone penetration. The increase in cost of software products is attributable to the acquisition of NVision Group at the end of 2015. The increase in roaming expenses is mainly attributable to the increase in traffic. The rise of the salary and social contributions resulted from the increase in number of employees. Electricity and rental charges for network placement increased due to inflation and growth of the number of rented sites.

        Russia convergent revenues for the year ended December 31, 2016, increased by 1.2% to RUB 359,905 million from RUB 355,776 million for the year ended December 31, 2015.

Revenue from voice and data tariffs increased due to active promotion of such tariffs, significant volume of Internet traffic included and the constant improvement of services provided. Revenues from sales of handsets and accessories increased to RUB 44,651 million in the year ended December 31, 2016 from RUB 39,392 million in the year ended December 31, 2015 due to pricing strategy aimed to push subscribers data adoption and attract new subscribers.

B.  Liquidity and Capital Resources

        Our borrowings consist of notes and bank loans. Since 2001, we have raised a total of $3.0 billion (RUB 92.8 billion at the date of transactions) through seven U.S. dollar-denominated unsecured bond offerings in the international capital markets, as well as ruble-denominated bonds totaling RUB 151 billion. Our bank loans consist of U.S. dollar-, euro-, and ruble- denominated borrowings totaling approximately RUB 182.9 billion as of December 31, 2017. We repaid approximately RUB 45.1 billion of indebtedness in 2017. As of December 31, 2017, the total amount available to us under our credit facilities amounted to RUB 36 billion. We had total indebtedness of approximately RUB 303.6 billion as of December 31, 2017, including capital lease obligations, compared to approximately RUB 284.3 billion as of December 31, 2016. Our total finance costs for the years ended December 31, 2016 and 2017, was RUB 27.1 billion and RUB 26,1 billion, net of amounts of interest capitalized, respectively. See Note 15 to our audited consolidated financial statements for a description of our indebtedness.

Capital Requirements

        We need capital to finance the following:

•

capital expenditures, consisting of purchases of property, plant and equipment and intangible assets;



•

acquisitions;



•

repayment of debt and related interest payments;



•

changes in working capital; and



•

general corporate activities, including dividends.

        We anticipate that capital expenditures, acquisitions, repayment of long-term debt and dividends will represent the most significant uses of funds for several years to come.

        Our cash outlays for capital expenditures in 2015, 2016 and 2017 were RUB 106,537 million, RUB 86,149 million and RUB 76,431 million respectively. We expect to continue to finance most of our capital expenditure needs through our operating cash flows, and to the extent required, to incur additional indebtedness through borrowings or additional capital raising activities. Historically, a significant portion of our capital expenditures have been related to the installation and build-out of our network and expansion into new license areas. We expect that capital expenditures will remain a large portion of our cash outflows in connection with the continued installation and build-out of our network. We expect our total capital expenditures in 2018 to be approximately 20% of our total 2017 revenue. These investments are required to support our subscriber base (i.e., to improve network capacity), to maintain and modernize our mobile and fixed line networks, to develop our network in the regions and to continue with the roll out of LTE networks throughout Russia as well as the development of our proprietary retail chain in Russia. We expect that the development of LTE networks will be among our most significant capital expenditures and require considerable management resources. See "Item 4. Information on Our Company—B. Business Overview—Mobile Operations—Services Offered—3G Technology" for additional information. Our actual capital expenditures may vary significantly from our estimates.

        In January 2015, the Group acquired 89.5% of Navigation Information Systems from Sistema for RUB 44 million. In July and December 2015, we acquired 100% share in the holding company NVision Group from subsidiaries of Sistema for RUB 11.2 billion. In December 2015, the Group increased its share in Stream LLC from 45% to 100% for RUB 1,650 million. In February 2016, we acquired 946,347 ordinary shares of MTS Bank, placed as part of an earlier approved additional issue, for a total consideration of RUB 1,325 million. On November 22, 2016 we acquired 2,637,310 ordinary shares of

MTS Bank of 10,000,000 shares, placed as a part of an earlier approved additional share issuance, for a total consideration of RUB 2,769 million. In September 2016, we acquired 100% of the shares of Smarts-Yoshkar-Ola CJSC ("Smarts-Yoshkar-Ola"), operating in the Republic of Mari El and holding rights to use 1800 MHz radio frequencies for RUB 13 million. In July 2017, we acquired a 100% ownership interest in Bashkortostan Cellular Communication OJSC ("BCC") for RUB 292 million. BCC operates in the Republic of Bashkortostan and holds rights to use 450 MHz and 2,100 MHz radio frequencies. In October 2017, we acquired 50.82% of ownership interest in the Russian retail software developer Oblachny Retail LLC ("Oblachny Retail"), operating under its trademark name LiteBox, for RUB 590 million. The deal allows us to enter the cloud-based cash register market as a fully licensed fiscal data operator (FDO) and a provider of integrated digital cash management solutions for B2B clients. In December 2017, we purchased a 100% ownership interest in Praliss Enterprises ("Praliss") for RUB 313 million, thus aquiring one of the world's leading eSport clubs—Gambit Esports.

        We also used cash provided by operating activities as well as external credit facilities to finance our capital expenditures. We plan to finance future acquisitions through operating cash flows and additional borrowings. We may continue to expand our business through acquisitions. Our cash requirements relating to potential acquisitions can vary significantly based on market opportunities.

        We expect to refinance our existing debt when it becomes due. For scheduled maturities of debt principal outstanding as of December 31, 2017 see Note 15 of our audited consolidated financial statements.We generally use the proceeds from our financing activities for our corporate purposes and refinancing existing indebtedness.

        Sistema, which currently controls 47.21% of our total charter capital (effective ownership of 50.04%) and consolidates our results in its financial statements, has a significant amount of outstanding debt and requires funds for debt service. These funds may come, in part, from dividends paid by its subsidiaries, including us. Our shareholders approved annual dividends for 2015 in the amount of RUB 27,997 million (including dividends on treasury shares in the amount of RUB 119 million), semi-annual dividends for 2016 in the amount of RUB 23,961 million (including dividends on treasury shares in the amount of RUB 102 million). Our shareholders approved annual dividends for 2016 in the amount of RUB 31,175 million (including dividends on treasury shares in the amount of RUB 666 million), semi-annual dividends for 2017 in the amount of RUB 20,783 million (including dividends on treasury shares in the amount of RUB 671 million). As of December 31, 2017 and 2016 dividends payable were RUB 125,4 and RUB 87,0 million, respectively, and included in the trade and other payables of the statement of financial position.

        We generally intend to finance our dividend requirements through operating cash flows, and accordingly, our payment of dividends may make us more reliant on external sources of capital to finance our capital expenditures and acquisitions.

Capital Resources

        We plan to finance our capital requirements through a mix of operating cash flows and financing activities, as described above. Our major sources of cash have been cash provided by operations and the proceeds of our U.S. dollar-denominated and ruble-denominated note issuances and loans. We expect that these sources will continue to be our principal sources of cash in the future.

        The availability of financing is influenced by many factors, including our profitability, operating cash flows, debt levels, credit ratings, contractual restrictions and market conditions. We cannot assure you that we will be able to continue to obtain large amounts of financing in the future through debt or equity offerings, bank financings or otherwise.

Table of Contents

        For the year, ended December 31, 2017, net cash provided by operating activities was RUB 144,640 million, a increase of 10.8% from the year ended December 31, 2016. The increase was mainly driven by our improved operating performance through out the year.

        Net cash used in investing activities for the year ended December 31, 2017 totaled to RUB 81,510 million, an increase of 42.2% in comparison with 2016. The increase in the amount of RUB 23,978 million was attributable to higher cash outflow relating to bank deposits, investments in Sistema-Capital trust management as well as investing in publicly traded debt securities. At the same time the cash inflows from investing in deposits reduced by RUB 13,636 million in 2017 compared to 2016, as in 2016 we got significant cash inflow related to deposits opened in previous years. Positive effect on net cash used in investing activity was attributable to lower capital expenditires and reduced investments in associates, the effects amounted to RUB 9,718 million and RUB 3,371 million, respectively

        Net cash used in financing activities for the year ended December 31, 2017 decreased by RUB 32,593 million or 39.2%, and totaled to RUB 50,445 million. The decrease was mainly due to decline in repayments and growth of proceeds from notes and loans by RUB 45,175 million and RUB 9,440 million, respectively. The positive effect from movements in our debt was partially offset by increase in cash outflows related to our share repurchase program, they grew by RUB 21,148 million in comparison to prior period.

        For the year, ended December 31, 2016, net cash provided by operating activities was RUB 130,565 million, a deacrease of 10.3% from the year ended December 31, 2015. The decrease was mainly attributable to increase by RUB 2,044 million of income tax payments (due to growth of taxable profit), increase of interest payments by RUB 1,577 million (RUB 3,045 million therof related to Eurobond repurchase in June 2016), decrease by RUB 1,416 million of interest received (due to lower investiments in deposits), as well as changes in timing of settlements with our customers and suppliers (change in cash outflow related to trade and other receivables and trade and other payables was RUB 11,691 million).

        Net cash used in investing activities for the year ended December 31, 2016 totaled to RUB 57,302 million, a reduction of 60.6% in comparison with 2015. In 2016 we reduced our capital expendures by RUB 20,388 million, as well as investing in deposits and loans by RUB 63,746 million. Positive effect of RUB 7,344 million was also attributable to cash inflows from deposits opened in prior year and closed in 2016, furthermore we received more cash from sales of property, plant and equipment and intangible assets (increase by RUB 1,054 million, thereof RUB 848 million for radiofrequences won by other operators). The only growing investing cash outflow related to investment in associates, we spent RUB 4,094 million for additional share issuance of MTS Bank.

        Net cash used in financing activities for the year ended December 31, 2016 increased by RUB 55,443 million or 200.9%, and totaled to RUB 83,038 million. The growth was mainly due to increased debt repayment and repayment under credit guarantee agreement related to foreigh currency hedge (due to appreciation of Russian Ruble). The respective cash outflows rose by RUB 49,746 million and RUB 9,690 million. Cash flows from transactions under common control had a positive effect of RUB 7,884 million on net cash used in financiang activities as there were no new transaction on sale or purchase of subsidiaries under common control. In 2016 proceeds from loans and notes reduced by RUB 2,471 million. The amount of dividends paid by the Group in 2016 increased by RUB 2,019 million in comparison with the financial year, ended December 31, 2015.

Liquidity

        As of December 31, 2017, we had total cash and cash equivalents of RUB 30,586 million (RUB 23,474 million in rubles, RUB 3,722 million in U.S. dollars, RUB 1,267 million in Turkmenistan manat, RUB 983 million in euros, RUB 755 million in Ukrainian hryvnias and RUB 385 million in

other currencies). In addition, as of December 31, 2017, we had short-term investments of RUB 50,757 million, mostly in form of deposits in various banks as well as debt securities (assets in Sistema-Capital trust management) and loans. We also had RUB 36,000 million available under existing credit facilities as of December 31, 2017. For a description of our outstanding external financing, see Note 15 to our audited consolidated financial statements.

        As of December 31, 2017, we had a working capital deficit of RUB 10,639 million compared to a deficit of RUB 36,551 million as of December 31, 2016. Our current assets increased by RUB 55,038 million as we generated more cash and cash equivalents (changed by RUB 12,116 million) and increased our short-term investments in 2017 (changed by RUB 42,100 million). Our current liabilities increased by RUB 29,126 million in 2017 mainly due to higher amount of short-term debt (changed by RUB 17,267 million), trade and other payables (changed by RUB 5,841 million), subscriber prepayments and other advances (changed by RUB 2,418 million) and provisions (changed by RUB 1,777 million). We expect to repay all long-term debts as they become due from our operating cash flows or through re-financings. We believe that our working capital, together with our plans for external financing, will provide us with sufficient funds for our present requirements.

        Russian law requires that dividends can only be paid in an amount not exceeding net profits as determined under Russian accounting standards, denominated in rubles, after certain deductions. In addition, dividends may only be paid if the value of the company's net assets is not less than the sum of the company's charter capital, the company's reserve fund and the difference between the liquidation value and the par value of the issued and outstanding preferred stock of the company, if any, as determined under Russian accounting standards. Our net income under Russian accounting standards for the years ended December 31, 2017 and 2016 that was distributable under Russian legislation amounted to RUB 125,091 million and RUB 50,659 million respectively.

Credit Rating Discussion

        Our credit ratings impact our ability to obtain short- and long-term financing, and the cost of such financing, and credit rating downgrades may require us to prepay certain loans. In determining our credit ratings, the rating agencies consider a number of factors, including our operating cash flows, total debt outstanding, commitments, interest requirements, liquidity needs and availability of liquidity. Other factors considered may include our business strategy, the condition of our industry and our position within the industry and the strategy, activity and/or credit rating of Sistema. Although we understand that these and other factors are among those considered by the rating agencies, each agency might calculate and weigh each factor differently. See "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—The controlling shareholder has a possibility to determine certain decisions of our governing bodies."

D.  Trend Information

Sales

        In 2017, our revenues in Russia increased by 2.9% and in Ukraine decreased by 10.6%. Our mobile subscriber base decreased to 101.2 million subscribers as of December 31, 2017 from 104.6 million subscribers as of December 31, 2016. We expect our consolidated subscriber base to remain stable in 2018 as a result of continued marketing and advertising activity. We anticipate our consolidated revenues will increase in 2018 mainly based on growth in data usage, the development of our broadband business in the regions and growth in sales of handsets and accessories.

        Average monthly minutes of use per subscriber in Russia remained stable and amounted to 383 minutes in 2017 as compared to 380 minutes in 2016. We expect an increase in megabytes of use per subscriber due to our efforts aimed at stimulating data usage and on-net traffic.

        In Ukraine, our subscriber base slightly decreased to approximately 20.8 million subscribers as of December 31, 2017, from 20.9 million subscribers as of December 31, 2016. During 2016-2017, VF Ukraine actively expanded its network and a high-speed mobile internet is now available for approximately 80% of Ukrainians now. In January 2018, VF Ukraine secured the first 4G license in the 2600 MHz band. Further development of 3G network, construction and development of 4G network will strengthen the market position of VF Ukraine. In 2018, we expect revenues to remain stable under the impact of the weaker macroeconomic environment.

        Our subscriber base in Armenia remained stable and amounted to 2.1 million subscribers in 2017. We expect the growth of competition in these markets which may, in turn, lead to decreasing tariffs, the addition of lower-value mass market subscribers and macroeconomic trends calling for "save mode."

        From September 29, 2017, the Group stopped providing communication services in Turkmenistan due to the actions of the state-owned telecommunication company Turkmentelekom, which resulted in disconnection of international and long-distance zonal communication services and internet access of our customers in Turkmenistan. At that moment our subscriber base amounted to 1.7 million subscribers or 30% of market according our estimates.

        Russia and Ukraine are the two largest markets for us, both in terms of subscribers and revenue. In 2017, the underlying developments within these markets remained generally positive and included high mobile penetration, strong demand for mobile services, generally positive usage trends and increased consumption of data services and value-added services. We expect growth of business activity in Russia to continue throughout 2018. We also expect that the stabilizing of the political situation in Ukraine will allow us to retain our operating indicators.

        We expect a challenging operating environment in 2018 due to continued macroeconomic and market volatility in the countries where we operate, increasing competition and significant changes in the mobile retail market in Russia. We also experienced significant exchange rate volatility and depreciation of local currencies in the countries where we operate against the U.S. dollar. The volatility and devaluation of local currencies against the U.S. dollar and/or euro may adversely affect our costs, including our non-cash foreign exchange loss due to the translation of our U.S. dollar- and euro-denominated debt. For further information on these risks, see "—A. Operating Results—Certain Factors Affecting our Financial Position and Results of Operations—Currency Fluctuations," and "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Financial Condition—Inflation could increase our costs and adversely affect our results of operations."

        However, considering current macroeconomic conditions, our management believes that we will experience medium- and long-term growth and efficiency. Due to the fact that the Russian and the Ukrainian markets are highly penetrated, we believe the next wave of revenue growth for the overall market is likely to come from customers' increasing use of data, content and other value-added services.

Moscow Fixed Line Operations

        In 2017 total revenue of MGTS decreased by 1.3%. The decline consists of two different trends. We see the continuing decline of fixed line voice services market and related revenue. In 2017 MGTS' fixed line voice services revenue decreased by 9.3%. In 2017, the subscriber base of B2C and B2B segments decreased by 4.3% and 6.4%, respectively. We expect further reduction of MGTS' revenue from fixed line voice services due to the decrease in subscriber base in 2018.

        However, we observe a growth in revenues from other services provided by MGTS to customers. MGTS' revenue from broadband Internet services increased by 12.3%. The increase was driven by high quality of services, profitable tariffs and operation optimization that led the transition of subscribers from competitors. MGTS' revenue from digital TV services increased by 25% in 2017. The growth mainly falls to B2C market, where MGTS is the leader in terms of the growth and the number of TV subscribers. In 2018, we expect further growth of revenue from broadband Internet and digital TV services mainly due to increase in the subscriber base.

        In 2017, MGTS' revenue from data services in B2G segment decreased by 7.6% due to the termination of some contracts with government customers. In 2018, we expect further reduction of MGTS' revenue from data services in B2G segment.

Churn

        We define churn as the total number of subscribers who cease to be a subscriber during the period (whether involuntarily due to non-payment or voluntarily), expressed as a percentage of the average number of our subscribers during that period.

        A vast majority of our subscribers are prepaid subscribers with no contractual commitment to us. As a result, these subscribers have unfettered freedom to migrate between operators at their convenience. This freedom, combined with the relative ease with which subscribers can obtain SIM cards, contributes to churn and increasing penetration levels in the markets where we operate.

        The churn rate is highly dependent on competition in our license areas and those subscribers who migrate as a result of such competition. Our churn rate in Russia remained relatively stable at around 39% for the year ended December 31, 2017. We continued to offer our popular tariff plans "Super MTS" (free calls to all subscribers of MTS Russia) and "Smart" (integrated voice and data bundles), updated options for unlimited mobile Internet, further improved network quality and enhanced data rate through the expansion of our 3G and LTE capabilities. We expect that the extension of the MTS-Bonus loyalty program and further development of our mono-brand retail network will allow us to keep churn rate under control in 2018, stimulate data usage and promote subscriber loyalty through superior customer service.

        The churn rate in Ukraine slightly increased to 26.6% for the year ended December 31, 2017, from 25.0% for the year ended December 31, 2016. In 2018, we expect subscriber loyalty to grow due to the launch of 3G-enabled data services with the support of our brand partnership with Vodafone.

Moscow Fixed Line Operations Churn

        Churn reduction and customer loyalty increase are among the most important areas of focus of MGTS. The churn rate differs for different services. Fixed line voice services is the fundamental service of MGTS. The churn rate for fixed line services of MGTS slightly increased to 4.9% during the year ended December 31, 2017, as compared to 4.6% for the year ended December 31, 2016. MGTS intends to reduce the churn rate for fixed line services in 2018 and keep it at the level of 4.8% through implementation of a number of measures, including banning telephone spam, bonus programs and other.

        The churn rate for broadband Internet services of MGTS decreased to 7.9% during the year ended December 31, 2017, as compared to 9.1% for the year ended December 31, 2016. The churn rate for Digital TV services of MGTS decreased to 8.5% during the year ended December 31, 2017, as compared to 10.8% for the year ended December 31, 2016. The decrease of churn rate for broadband Internet and Digital TV services was achieved due to technological optimization of user equipment, new services and competitive tariffs for quality services. MGTS plans to increase subscriber loyalty in 2018 in order to consolidate its leading position on the market.

E.  Off-balance Sheet Arrangements

        We believe that our existing off-balance sheet arrangements do not have and are not reasonably likely to have a current or future effect on our financial condition, changes in financial condition, revenues or expenses, results of operations, liquidity, capital expenditures or capital resources that is material to investors.

Obligations under derivative contracts

        We regularly enter into variable-to-fixed interest rate swap agreements to eliminate the exposure of changes in value of debt obligations. The instruments qualify for cash flow hedge accounting under IFRS requirements. Each interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective hedges. Interest rate swap contracts outstanding December 31, 2017 mature in 2018 and 2020.

        In addition to the above, we have also entered into several cross-currency interest rate swap agreements. These contracts hedged the risk of both interest rate and currency fluctuations and assumed periodic exchanges of both principal and interest payments from RUB-denominated amounts to USD-denominated amounts to be exchanged at a specified rate. The rate was determined by the market spot rate upon issuance. Each interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective hedges. Cross-currency interest rate swap contracts mature in 2019-2024.

F.  Tabular Disclosure of Contractual Obligations

        We have various contractual obligations and commercial commitments to make future payments, including debt agreements, capital lease obligations (including interest) and certain committed

8.A.7. Litigation

Uzbekistan

        In June 2012, the authorities of the Republic of Uzbekistan commenced audits of the financial and operating activities of MTS' wholly-owned subsidiary Uzdunrobita. Further various claims for violation of tax, antimonopoly and industry legislation were made against Uzdunrobita, which resulted in significant amounts of fines and penalties, revocation of all licenses and suspension of services. Fines and penalties amounted to approximately RUB 18,375 million payable in equal installments over eight months.

        Uzdunrobita paid two scheduled installments in November and December 2012 totaling approximately RUB 4,583.4 million. On January 14, 2013, further to its partial payment of the third installment due in January 2013 totaling approximately RUB 481 million and constituting the remaining amount of cash held in its bank accounts, Uzdunrobita filed a petition for voluntary bankruptcy to the Tashkent Economic Court on the grounds of its inability to meet further obligations.

        Considering the adverse impact of such circumstances on the Group's ability to conduct operations in Uzbekistan, the Group tested goodwill and other long-lived assets attributable to Uzbekistan for impairment upon first receiving notification of the investigations. As a result, an impairment loss on the long-lived assets in the amount of RUB 20,037 million was recorded in the consolidated statements of profit or loss for the year ended December 31, 2012. In 2013 these losses were assigned to discontinued operations.

        In 2012, the Group filed a claim against the Republic of Uzbekistan in the International Center for Settlement of Investment Disputes ("ICSID"), part of the World Bank Group, in Washington, D.C.

        On April 22, 2013, the Tashkent Economic Court declared Uzdunrobita bankrupt and initiated a liquidation process. Uzdunrobita was later liquidated. As a result the Group lost control over the subsidiary and deconsolidated Uzdunrobita.

        In July 2014 the dispute between MTS and the Republic of Uzbekistan was resolved. The parties signed a settlement agreement (the "Settlement Agreement") and according to its terms all mutual claims were eliminated. The Settlement Agreement is governed by English law and provides for resolution of any disputes arising out of the Settlement Agreement in the International Court of Arbitration under the International Chamber of Commerce in Paris ("ICSID"). ICSID has discontinued international arbitration proceedings between us and the Republic of Uzbekistan following the submission of a joint application by both parties.

        The Republic of Uzbekistan established a legal entity, UMS, with such entity having no legal connection to the previously liquidated entity, Uzdunrobita. UMS was granted 2G, 3G and LTE licenses valid until 2029, and received frequencies, numbering capacity and other permits required for the launch of operations. On September 24, 2014, a 50.01% ownership interest in UMS was transferred to MTS by the State Unitary Enterprise Center of Radio Communications, Radio Broadcasting and Television on behalf of the Republic of Uzbekistan. We have also received certain guaranties in relation to the protection of any future investment in the Republic of Uzbekistan.

        In March 2014, we received requests for the provision of information from the SEC and the United States Department of Justice ("DOJ") relating to a currently conducted investigation of the our former subsidiary in Uzbekistan.

        In July 2015, activities related to our operations in Uzbekistan have been referenced in a civil forfeiture complaints ("The Complaints"), filed by DOJ in the U.S. District Court, Southern District of New York (Manhattan), directed at certain assets of an unnamed Uzbek government official. The Complaints allege among other things that we and certain other parties made corrupt payments to the unnamed Uzbek official to assist their entering and operating in the Uzbekistan telecommunications market. The Complaints are solely directed towards assets held by the unnamed Uzbek official and none of our assets are affected by the Complaints.

        We continue to cooperate with these investigations. We, the DOJ and the SEC are having discussions about a potential resolution to allegations of non-compliance with the Foreign Corrupt Practices Act (FCPA). However, at this stage, the Group cannot be certain that such discussions will result in a settled resolution or whether there will be further developments in the investigations.

        For additional information please refer to Note 27 and 30 to our audited consolidated financial statements.

Other litigation

        In August 2012, we received a claim regarding dismissal of international registration of four of the Group trademarks in the territory of Ukraine from an entity named MTS LLC. The claim was fully dismissed by Economic Appeal Court of Kiev in December 2013. However, in the end of 2015, following claims of MTS LLC, two regional courts of Ukraine dismissed international registration of our trademarks in the territory of Ukraine. In March 2016, we appealed the decisions of two regional courts. Our appeals were fully satisfied. In May 2016, MTS LLC submitted a claim regarding dismissal of international registration of eight of the Group trademarks in the territory of Ukraine to the Economic Court of Kiev. We submitted to the Economic Court of Kiev counterclaim regarding dismissal of registration of MTS LLC trademark and the Economic Court of Kiev suspended processing MTS LLC claim till consideration of our counterclaim. In March 2017, our counterclaim was satisfied in the court of cassation. In May 2017, due to the State Intellectual Property Service of Ukraine failure to cancel the disputed certificates registration we filed an application to Kiev Court of Appeal for a turnaround in the enforcement of the court decision, which was satisfied. In September 2017, data on the early termination of the validity of our trademarks was published in the bulletin of industrial property.

Tax Audits and Claims

        In the ordinary course of business, we may be party to various tax proceedings, and subject to tax claims, some of which relate to the developing markets and evolving fiscal and regulatory environments in which we operate. In the opinion of management, our liability, if any, in all pending tax proceedings or tax claims will not have a material effect on our financial condition, results of operations or liquidity. We believe that we have adequately provided for tax liabilities in the accompanying consolidated financial statements; however, the risk remains that relevant authorities could take differing positions with regard to interpretive issues and the effect could be significant. See also Note 29 to our audited consolidated financial statements.

        In October 2015, the Russian tax authorities completed a tax audit of Comstar Regions CJSC for the years ended December 31, 2012 and 2013.

In April 2017, the FAS found us, MegaFon and VEON Ltd. (VimpelCom) responsible for the aforementioned violation. VEON Ltd. (VimpelCom) and Tele2 appealed the FAS decision in the Arbitrazh Court. As a result Moscow Arbitrazh Court, the Ninth Arbitrazh Court of Appeal and the Court of Cassation declared the FAS decision unlawful.

        In November 2016, the FAS subdivision in Yaroslavl has charged MTS, MegaFon and VEON Ltd. (VimpelCom) with violation of antimonopoly laws in respect to 4G modems pricing. In September 2017, the investigation was ceased as no violation was found in operators' actions.

8.A.8. Dividend Distribution Policy

        Our dividend policy for the years 2013, 2014 and 2015 was aimed to make dividend payments to our shareholders in the amount of at least 75% of MTS' free cash flow, but not less than RUB 40 billion. For the purposes of dividend calculation we utilized a simplified form of free cash flow—which we define as Operating Cash Flow less capital expenditures.

        On April 8, 2016, our Board of Directors approved new dividend policy which sets a target payout of RUB 25.0 - 26.0 per ordinary MTS share (RUB 50.0 - 52.0 per ADR) per calendar year. The policy guarantees a minimum payout of RUB 20.0 per ordinary MTS share (or RUB 40.0 per ADR). The policy will cover 2016 - 2018. Payments will continue to be made on a semi-annual basis.

        Annual and semi-annual dividend payments, if any, must be recommended by Board of Directors and approved by the General Meeting of Shareholders (GM). We anticipate that any dividends we may pay in the future on the shares represented by the ADSs will be declared and paid to the depositary in rubles and will be converted into U.S. dollars by the depositary and distributed to holders of ADSs, net of the depositary's fees and expenses. Accordingly, the value of dividends received by holders of ADSs will be subject to fluctuations in the exchange rate between the ruble and the dollar.

        At a meeting held on April 11, 2018, the Board of Directors recommended that an AGM approves annual dividends of RUB 23.4 per ordinary MTS share (RUB 46.8 per ADS), or a total of approximately RUB 46.76 billion, based on the full-year 2017 financial results.

        The Board of Directors set the date for our AGM for June 28, 2018. The record date for the Company's shareholders and ADS holders entitled to participate in the AGM has been set for May 25, 2018. The Board of Directors recommended that the AGM sets the record date for shareholders and ADS holders entitled to receive dividends for the 2017 fiscal year for July 9, 2018.

Table of Contents

Our Purpose

        Article 2.1 of our charter provides that our principal purpose is to obtain profits through the planning, marketing, establishing and operating communications network and facilities, to provide access to Internet and to render communications services on our license territories.

        We are registered with the Federal Tax Service of the Russian Federation under the state registration number 1027700149124.

General Matters

        Pursuant to our charter, we have the right to issue common stock, preferred stock and other securities provided for by legal acts of the Russian Federation with respect to securities. Our capital stock currently consists of 1,998,381,575 common shares, each with a par value of 0.10 rubles, all of which are issued and fully paid. Under Russian legislation, charter capital refers to the aggregate par value of the issued and outstanding shares. We are also authorized to issue an additional 100,000,000 common shares with a par value of 0.10 rubles each. We have issued only common stock. No preferred shares are authorized or outstanding. Preferred stock may only be issued if corresponding amendments have been made to our charter pursuant to a resolution of the general meeting of shareholders.

        The Joint Stock Companies Law requires us to dispose any of our shares that we acquire within one year of their acquisition or, failing that, reduce our charter capital. We refer to such shares as treasury shares for the purposes hereof. Russian legislation does not allow for the voting of such treasury shares. Any of our shares that are owned by our subsidiaries are not considered treasury shares under Russian law (i.e., they are considered outstanding shares), and our subsidiaries holding such shares are able to vote and dispose of such shares without any further corporate actions by our shareholders or Board of Directors.

        In March 2016, in the course of liquidation of our wholly owned subsidiary, MTS Bermuda, we obtained 67,995,335 shares. As of June 1, 2016, we had 36,652 treasury shares repurchased pursuant to our shareholders' right to demand buy-out following the merger of our subsidiaries into MTS during 2015 and 2016 in accordance with applicable laws. In June 2016, our shareholders decided to decrease our charter capital by cancellation of all outstanding 68,031,987 treasury shares (approximately 3.29% of our share capital at that time). In August 2016, we cancelled these shares, and as such our capital stock decreased from 2,066,413,562 to 1,998,381,575 shares. As of April 1, 2017, we did not have any treasury shares.

        In August 2017, we repurchased 497 treasury shares pursuant to our shareholders' right to demand buy-out following the merger of our subsidiaries into MTS in accordance with applicable laws. As of December 31, 2017, we had 497 treasury shares.

        As of April 1, 2016, our subsidiaries held 9,496,163 of our shares. In April 2016, our wholly owned subsidiary Bastion LLC sold 954,386 shares to our management pursuant to our management long-term motivation program. In December 2016, our wholly owned subsidiary Stream Digital LLC purchased 3,060,409 shares (including shares represented by ADSs) as a result of a tender offer announced in October 2016.

        A second tender offer was announced in January 2017, as a result of which Stream Digital LLC purchased additional 32,061,256 shares. Thus, as of April 1, 2017, our subsidiaries held a total of 43,543,303 of our shares.

        To increase the shareholder return, we continued the repurchase of shares in the open market in 2017. As a result of open market purchases, as of December 31, 2017, our subsidiaries held a total of 86,339,156 of our shares.

Rights Attaching to Shares

        Holders of our common stock have the right to vote at all shareholders' meetings. As required by the Joint Stock Companies Law and our charter, all shares of our common stock have the same par value and grant identical rights to their holders.

•

if holding, alone or with other shareholders at least 1% of the voting shares, demand consent for an interested party transaction; and

Pre-emptive Rights

        The Joint Stock Companies Law and our charter provide existing shareholders with a pre-emptive right to purchase shares or securities convertible into shares during an open subscription in the amount proportionate to their existing shareholdings. In addition, the Joint Stock Companies Law provides shareholders with a pre-emptive right to purchase shares or securities convertible into shares, in an amount proportionate to their existing shareholdings, during a private subscription if the shareholders voted against or did not participate in the voting on the decision approving such subscription. The pre-emptive right does not apply to a private subscription to the existing shareholders provided that such shareholders may each acquire a whole number of shares or securities convertible into shares being placed in an amount proportionate to their existing shareholdings. We must provide shareholders with written notice of their pre-emptive right to purchase shares and the period during which shareholders can exercise their pre-emptive rights may not be less than 45 or, under certain circumstances, 20 or even eight business days. We cannot sell the shares or securities convertible into shares which are subject to the pre-emptive rights during this period.

Dividends

        The Joint Stock Companies Law and our charter set forth the procedure for determining the quarterly and annual dividends that we may distribute to our shareholders. We may declare dividends based on our first quarter, six month, nine month or annual results. Dividends are recommended to a shareholders' meeting by a majority vote of the Board of Directors and approved by the shareholders by a majority vote. A decision on quarterly, six month and nine month dividends must be taken within three months of the end of the respective quarter at the extraordinary shareholders' meeting; and a decision on annual dividends must be taken at the annual general shareholders' meeting. The dividend approved at the shareholders' meeting may not be more than the amount recommended by the Board of Directors.

        The Joint Stock Companies Law allows dividends to be declared generally out of net profits calculated under RAS as long as the following conditions have been met:

•

the charter capital of the company has been paid in full;

199

---

Table of Contents

•

the value of the company's net assets on the date of the adoption of the decision to pay dividends is not less (and would not become less as a result of the proposed dividend payment) than the sum of the company's charter capital, the company's reserve fund and the difference between the liquidation value and the par value of the issued and outstanding preferred stock of the company;



•

the company has repurchased all shares from shareholders having the right to demand repurchase; and



•

the company is not, and would not become, insolvent as the result of the proposed dividend payment.

        The Joint Stock Companies Law and the Securities Market Law have been amended on December 29, 2012 to adopt new dividend payment rules that came into force January 1, 2014. These amendments include new rules on determining the shareholders entitled to dividend distribution whereby the list of such shareholders is fixed at date determined in the decision of the General shareholders' meeting on the distribution of dividends. The date shall not be earlier than 10 days and later than 20 days following the date of such decision. The dividends are to be paid to private shareholders registered in the share register of the company within 25 business days and to nominal holders and professional managers within business 10 days from the date on which persons entitled to receive dividends are determined. If shares are held on a depo account with a depository, dividends will be transferred to such shareholders by such depositary within 7 business days of receipt of funds by the depositary.

Distributions to Shareholders on Liquidation

        Under Russian legislation, liquidation of a company results in its termination without the transfer of rights and obligations to other persons as legal successors. The Joint Stock Companies Law and our charter allow us to be liquidated:

•

by a three-quarters majority vote of a shareholders' meeting; or



•

by a court order.

        Following a decision to liquidate us, the right to manage our affairs would pass to a liquidation commission appointed by a shareholders' meeting. In the event of an involuntary liquidation, the court may assign the duty to liquidate the company to its shareholders. Creditors may file claims within a period to be determined by the liquidation commission, but such period must not be less than two months from the date of publication of notice of liquidation by the liquidation commission.

        The Civil Code of the Russian Federation gives creditors the following order of priority during liquidation:

•

individuals owed compensation for injuries or deaths;



•

employees and authors of intellectual property;



•

federal and local governmental entities claiming taxes and similar payments to the federal and local budgets and to non-budgetary funds; and



•

other creditors in accordance with Russian legislation.

        Claims of creditors in obligations secured by a pledge of the company's property ("secured claims") are satisfied out of the proceeds of sale of the pledged property prior to claims of any other creditors except for the creditors of the first and second priorities described above, provided that claims of such creditors arose before the pledge agreements in respect of the company's property were made. To the extent that the proceeds of sale of the pledged property are not sufficient to satisfy secured

200

Table of Contents

claims, the latter are satisfied simultaneously with claims of the fourth priority creditors as described above.

        The Federal Law on Insolvency (Bankruptcy), however, provides for a different order of priority for creditors' claims in the event of bankruptcy.

        The remaining assets of a company are distributed among shareholders in the following order of priority:

•

payments to repurchase shares from shareholders having the right to demand repurchase;



•

payments of declared but unpaid dividends on preferred shares and the liquidation value of the preferred shares determined by the company's charter, if any; and



•

payments to holders of common and preferred shares.

Liability of Shareholders

        The Civil Code of the Russian Federation and the Joint Stock Companies Law generally provide that shareholders in a Russian joint stock company are not liable for the obligations of a joint stock company and bear only the risk of loss of their investments. This may not be the case, however, when one company is capable of determining decisions made by another company. The company capable of determining such decisions is called an "effective parent." The company whose decisions are capable of being so determined is called an "effective subsidiary." The effective parent bears joint and several responsibility for transactions concluded by the effective subsidiary in carrying out these decisions if:

•

this decision-making capability is provided for in the charter of the effective subsidiary or in a contract between such persons; and



•

the effective parent gives binding instructions or consent for a transaction to the effective subsidiary (except for voting of the effective parent in a shareholders' meeting of its effective subsidiary and approval by the effective parent's governing body of a transaction if such approval is required under the charter of the effective parent or the effective subsidiary).

        In addition, an effective parent is secondarily liable for an effective subsidiary's debts if an effective subsidiary becomes insolvent or bankrupt resulting from the act or omission of an effective parent only when the effective parent has used the right to give binding instructions, knowing that the consequence of carrying out this act or omission would be insolvency of this effective subsidiary. This is the case no matter how the effective parent's capability to determine decisions of the effective subsidiary arises, in particular through ownership of voting securities or by contract. In these instances, other shareholders of the effective subsidiary may claim compensation for the effective subsidiary's losses from the effective parent that caused the effective subsidiary to take any action or fail to take any action knowing that such action or failure to take action would result in losses.

Alteration of Capital

Charter Capital Increase

        We may increase our charter capital by:

•

issuing new shares; or



•

increasing the par value of previously issued shares.

        A decision on any issuance of shares or securities convertible into shares by private subscription, or an issuance by open subscription of common shares or securities convertible into common shares constituting 25% or more of the number of issued common shares, requires a three-quarters majority vote of a shareholders' meeting. Otherwise, a decision to increase the charter capital by increasing the

201

---

Table of Contents

par value of issued shares requires a majority vote of a shareholders' meeting. In certain circumstances provided in our charter, a decision to increase the charter capital may be taken by our Board of Directors. In addition, the issuance of shares above the number provided in our charter necessitates a charter amendment, which requires a three-quarters affirmative vote of a shareholders' meeting.

        The Joint Stock Companies Law requires that the value of newly issued shares be determined by the board of directors based on their market value but not less than their par value. The price of newly issued shares for existing shareholders exercising their pre-emptive right to purchase shares could be less than the price paid by third parties, but not less than 90% of the price paid by third parties. Fees paid to intermediaries may not exceed 10% of the shares placement price. The board of directors shall value any in-kind contributions for new shares, based on the appraisal report of an appraiser.

        Russian securities regulations set out detailed procedures for the issuance and registration of shares of a joint stock company. These procedures require:

•

taking a decision on a share placement;



•

approval of a resolution on a share issuance;



•

prior registration of the share issuance with the CBR;



•

placement of shares;



•

filing with the CBR and registration of a report or a notice (as applicable) on results of the share issuance; and



•

public disclosure of information relating to the issuance of shares.

Charter Capital Decrease; Share Buy-Backs

        The Joint Stock Companies Law does not allow a company to reduce its charter capital below the minimum charter capital required by law, which is 100,000 rubles for a public joint stock company. The Joint Stock Companies Law and our charter require that any decision to reduce our charter capital through the repurchase and cancellation of shares, be made by a majority vote of a shareholders' meeting and through reduction of the par value of shares, by a three-quarter majority vote of a shareholders' meeting. Additionally, within three business days of a decision to reduce our charter capital, we must notify the federal executive body in charge of the state registration of legal entities on the decision taken and publish within the same three-day period a notice regarding the charter capital reduction, as well as a second notice one month after the first notice is published. Our creditors, whose claims arose before the decision on the charter capital decrease was taken, would then have the right to demand, not later than 30 days of the second publication of the notice, early termination or settlement of relevant obligations by us, as well as compensation for damages.

        The Joint Stock Companies Law and our charter allow our shareholders or the Board of Directors to authorize the repurchase of up to 10% of our shares in exchange for cash. The repurchased shares pursuant to a board decision must be resold at the market price within one year of their repurchase or, failing that, the shareholders must decide to cancel such shares and decrease the charter capital. Repurchased shares do not bear voting rights.

        Shares repurchased pursuant to a decision of our shareholders' meeting to decrease the overall number of shares are cancelled at their redemption.

        The Joint Stock Companies Law allows us to repurchase our shares only if, at the time of repurchase:

•

our charter capital is paid in full;



•

we are not and would not become, as a result of the repurchase, insolvent;

202

---

Table of Contents

•

the value of our net assets at the time of repurchase of our shares is not less (and would not become less, as a result of the proposed repurchase) than the sum of our charter capital, the reserve fund and the difference between the liquidation value and par value of our issued and outstanding preferred shares; and



•

we have repurchased all shares from shareholders having the right to demand repurchase of their shares in accordance with Russian law, as described immediately below.

        Our subsidiaries are not restricted from purchasing our shares, and our subsidiaries can vote these shares.

        The Joint Stock Companies Law and our charter provide that our shareholders may demand repurchase of all or some of their shares as long as the shareholder demanding repurchase voted against or did not participate in the voting on the decision approving any of the following actions:

•

any reorganization;



•

the conclusion of a major transaction, which involves assets having value of more than 50% of the balance sheet value of the assets calculated under RAS (including those which are simultaneously interested party transactions); or



•

any amendment of our charter or approval of a restated version of our charter in a manner which restricts shareholders' rights; and



•

the amendment of the public company's charter which eliminates indication that the company is public, simultaneously with the decision on applying to the CBR on release from obligation to disclose information under the laws of the Russian Federation on securities and the decision on applying for delisting of shares and equity securities convertible into shares (i.e., transformation to a non-public company).

        We may spend up to 10% of our net assets calculated under RAS on the date of the adoption of the decision which gives rise to a share redemption demanded by the shareholders. If the value of shares in respect of which shareholders have exercised their right to demand repurchase exceeds 10% of our net assets, we will repurchase shares from each such shareholder on a pro-rata basis. Repurchase of the shares is made at a price agreed on by the board of directors, but it should not be less than the market price.

Registration and Transfer of Shares

        Russian legislation requires that a joint stock company ensures maintenance of a register of its shareholders, which for a public joint stock company, shall be maintained by a registrar. Registrar NIKoil OJSC had maintained our register of shareholders since May 10, 2000. In July 2014, it has been merged into Independent Registration Company JSC (known as Computershare Registrar JSC prior to October 6, 2015) which now maintains our register of shareholders due to universal succession.

        The Federal Law No. 414-FZ "On the Central Depositary" dated December 7, 2011 (the "Central Depositary Law"), which came into force on January 1, 2012, set out a legal framework for establishment and operation of the central depositary. On November 6, 2012, the Russian Federal Financial Markets Service granted the JSC National Settlement Depositary the status of central depositary which opened its nominee holder accounts in, among others, all securities registers of the issuers which are obliged to disclose information in accordance with Russian securities law. As we are required to make public disclosures, the above requirement is applicable to us, which means that the central depositary became the only person having a nominee holder account in our share register. Also, the Central Depositary Law prohibits persons maintaining securities registers from opening and depositing securities (save for limited exceptions) to other nominee holder accounts from the date of the opening of a nominee holder account with the central depositary.

203

Table of Contents

        Ownership of our registered shares is evidenced by entries made in the register of shareholders, on the books of the central depositary or a Russian licensed depositary. Any of our shareholders may obtain an extract from the register of our shareholders maintained by the registrar or from their respective depositary, as the case may be, certifying the number of shares that such shareholder holds. We are also entitled to obtain an extract from our shareholders' register which sets out all of our shareholders registered directly therein. In addition, we are entitled to obtain a list of nominal holders that opened depo accounts with the central depository, as well as a list of entities that have accounts opened with the nominal holders, given that such list is provided by the relevant nominal holder. However, we are unable to monitor transfers of our shares that are held on the books of depositaries registered with the central depository because underlying shareholders have no obligation to reveal and such depositaries have no obligation to notify us about such transfers. As a result, we can currently only identify our actual shareholders in a limited number of cases provided for by Russian law, including when requesting our registrar and the central depository to compile a list of shareholders of record for the General Shareholders' Meeting and when shareholders and ADS holders provide voting instructions together with disclosure of information, including ownership information, in accordance with Russian securities regulations.

        The purchase, sale or other transfer of shares is accomplished through the registration of the transfer in the shareholder register, or the registration of the transfer with a depositary if shares are held by a depositary. The registrar or depositary may not require any documents in addition to those required by Russian legislation in order to transfer shares in the register. Refusal to register the shares in the name of the transferee or, upon request of the beneficial holder, in the name of a nominee holder, is not allowed, except for certain instances provided for by Russian legislation, and may be challenged in court.

Reserve Fund

        Russian legislation requires that each joint stock company establish a reserve fund to be used only to cover the company's losses, redeem the company's bonds and repurchase the company's shares in cases when other funds are not available. Our charter provides for a reserve fund of 15% of our charter capital, funded through mandatory annual transfers of at least 5% of our net profits until the reserve fund has reached the 15% requirement.

Disclosure of Information

        Russian securities regulations require us to make the following periodic public disclosures and filings:

•

posting on our website quarterly reports, containing information about us, our shareholders and depositary, the structure of our management bodies, the members of the Board of Directors, our branches and representative offices, our shares, bank accounts and auditors, important developments during the reporting quarter, and other information about our financial and business activity;



•

General Shareholders' Meetings

Procedure

        The powers of a shareholders' meeting are set forth in the Joint Stock Companies Law and in our charter. In a public joint stock company a shareholders' meeting may not decide on issues that are not included in the list of its competence by the Joint Stock Companies Law. Among the issues which our shareholders have the power to decide are:

•

charter amendments;



•

reorganization or liquidation;



•

election and removal of members of the board of directors;



•

determination of the amount of compensation for members of the board of directors;



•

determination of the number, par value, class/type of authorized shares and the rights granted by such shares;



•

other issues, as provided for by the Joint Stock Companies Law and our charter.

        Voting at a shareholders' meeting is generally based on the principle of one vote per share of common stock, with the exception of the election of the board of directors, which is done through cumulative voting. Decisions are generally passed by a majority vote of the voting shares present at a shareholders' meeting. However, for public joint stock companies Russian law requires a three-quarters majority vote of the voting shares present at a shareholders' meeting to approve the following:

•

charter amendments;



•

reorganization or liquidation;



•

consent or subsequent approval of major transactions involving assets in excess of 50% of the balance sheet value of the company's assets calculated under RAS;

•

repurchase by the company of its issued shares;



•

any issuance of shares or securities convertible into shares of common stock by private subscription;



•

issuance by open subscription of shares of common stock or securities convertible into common stock, in each case, constituting 25% or more of the number of issued and outstanding shares of common stock;



•

decrease of the charter capital through reduction of the par value of shares; or



•

filing of an application for delisting of our shares or securities convertible into shares.

        Moreover, a ninety-five majority vote of the voting shares present at a shareholders' meeting is required to approve the amendment of the public company's charter which eliminates indication that the company is public, simultaneously with the decision on applying to the CBR on release from obligation to disclose information under the laws of the Russian Federation on securities and the decision on applying for delisting of shares and equity securities convertible into shares (i.e., transformation to a non-public company).

        The quorum requirement for our shareholders' meetings is met if holders of shares (or their representatives) accounting for more than 50% of the issued voting shares are present. If the 50% quorum requirement is not met, another shareholders' meeting with the same agenda may (and, in case of an annual shareholders' meeting must) be scheduled and the quorum requirement is satisfied if holders of shares (or their representatives) accounting for at least 30% of the issued voting shares are present at that meeting.

        The annual shareholders' meeting must be convened by the board of directors between March 1 and June 30 of each year, and the agenda must include the following items:

•

election of the members of the board of directors;



•

approval of the annual report and the annual financial statements, including the balance sheet and profit and loss statement;



•

approval of distribution of profits, including approval of dividends, and losses, if any;



•

appointment of an independent auditor; and



•

appointment of the members of the auditing commission.

        A shareholder or group of shareholders owning in the aggregate at least 2% of the issued voting shares may introduce proposals for the agenda of the annual shareholders' meeting and may nominate candidates for the board of directors, counting commission and auditing commission. Any agenda proposals or nominations must be provided to the company no later than 100 calendar days after the preceding financial year end.

        Extraordinary shareholders' meetings may be called by the board of directors on its own initiative, or at the request of the auditing commission, the independent auditor or a shareholder or group of shareholders owning in the aggregate at least 10% of the issued voting shares as of the date of the request. The decision to call or reject the call for an extraordinary shareholders' meeting shall be made by the board of directors within five days from the receipt date of the request and sent to the party that requested the meeting within three days after such a decision was made.

        A general meeting of shareholders may be held in a form of a meeting or by absentee ballot. The form of a meeting contemplates the adoption of resolutions by the general meeting of shareholders

206

through the attendance of the shareholders or their authorized representatives for the purpose of discussing and voting on issues of the agenda, provided that if a ballot is mailed to shareholders for participation at a meeting convened in such form, the shareholders may complete and mail the ballot back to the company without personally attending the meeting. A general meeting of the shareholders by absentee ballot contemplates the determination of collecting shareholders' opinions on issues of the agenda by means of a written poll.

        The following issues cannot be decided by a shareholders' meeting by absentee ballot:

•

election of the members of the board of directors;



•

election of the auditing commission;

However, if it is an extraordinary shareholders' meeting to elect the board of directors, persons registered in the register of shareholders and entitled to participate in the general shareholder's meeting must be notified at least 50 days prior to the date of the meeting. Only those items that were set out in the agenda to shareholders may be voted upon at a general shareholders' meeting.

        If a nominal holder of the shares registers in the register of shareholders, then a notification of the shareholders' meeting shall be sent to the nominal holder. The nominal holder must notify its clients in accordance with Russian legislation or an agreement with the client. The list of persons entitled to participate in a general shareholders' meeting is to be compiled on the basis of data in our shareholders register on the date established by the board of directors, which date may neither be earlier than the 10 days after the date of adoption of the board resolution to hold a general shareholders' meeting nor more than 25 days before the date of the meeting (or, in the case of an extraordinary shareholders' meeting to elect the board of directors, not later than 55 days before the date of the meeting).

        The right to participate in a general meeting of shareholders may be exercised by a shareholder as follows:

•

by personally participating in the discussion of agenda items and voting thereon;



•

by sending an authorized representative to participate in the discussion of agenda items and to vote thereon;



•

by submitting a written ballot reflecting the shareholders' voting on the agenda items;



•

by delegating the right to submit such written ballot to an authorized representative; or



•

by sending information on their willingness to the nominee holder for further transfer to the registrar in accordance with the requirements of the Russian securities law.

Board of Directors

        Our Board of Directors is elected through cumulative voting. Under cumulative voting, each shareholder may cast an aggregate number of votes equal to the number of shares held by such shareholder multiplied by the number of persons to be elected to our Board of Directors, and the shareholder may give all such votes to one candidate or spread them between two or more candidates. Before the expiration of their term, the directors may be removed as a group at any time without cause by a majority vote of a shareholders' meeting.

        The Joint Stock Companies Law requires at least a five-member board of directors for all joint stock companies, at least a seven-member board of directors for a joint stock company with more than 1,000 holders of voting shares, and at least a nine-member board of directors for a joint stock company with more than 10,000 holders of voting shares. Only natural persons (as opposed to legal entities) are entitled to sit on the board. Members of the board of directors are not required to be shareholders of the company. The actual number of directors is determined by the company's charter or a decision of the shareholders' meeting. Our charter provides that our Board of Directors consists of at least seven members, which number may be increased pursuant to a decision of the general meeting of shareholders. Currently, our Board of Directors consists of nine members.

        The Joint Stock Companies Law prohibits a board of directors from acting on issues that fall within the competence of the general shareholders' meeting. Our Board of Directors has the power to perform the general management of the company, and to decide, among others, the following issues:

•

determination of our business priorities;



•

approval of our annual plans, including financial plans;



•

convening annual and extraordinary shareholders' meetings, except for certain circumstances specified in the Joint Stock Companies Law;

        Our charter generally requires a majority vote of the directors present for an action to pass, with the exception of actions for which Russian legislation requires a unanimous vote or a majority vote of the disinterested and independent directors, as described therein. A board meeting is considered duly assembled and legally competent to act when a majority of elected directors is present.

Interested Party Transactions

        Under the Joint Stock Companies Law, certain transactions are defined as "interested party transactions." Such transactions include transactions involving a member of the board of directors, the company's CEO, a member of the company's management board), any person controlling the company, or any person who is able to give binding instructions to the company, if that person and/or that person's spouse, parents, children, adoptive parents or children, full and half brothers or sisters and/or their controlled entities, is/are:

A controlled entity is understood to be a legal entity directly or indirectly controlled by the controlling entity.

        Pursuant to the changes to the Joint Stock Companies Law, which entered into force on January 1, 2017, transactions defined as "interested party transactions" do not require a mandatory prior approval by disinterested directors or shareholders of the company. However, a company shall notify members of a board of directors, management board or shareholders (if all members of the board of directors are deemed interested or a board of directors is not formed in a company) of a contemplated interested party transaction not later than 15 days prior to execution of such transaction, and the company's sole executive body, members of its board of directors and management board or a shareholder owning at least 1% of the company's voting shares may request consent for such interested party transaction.

        In public joint stock companies consent or subsequent approval of the transaction shall be granted (if requested) by a majority of disinterested directors of the company which within one year prior to the decision:

•

did not act as persons performing functions of the sole executive body, including its executive manager, members of the company's management board or members of the management bodies of the company's managing organization;



•

Major Transactions

        The Joint Stock Companies Law defines a "major transaction" as a transaction, or a number of interrelated transactions entered into beyond the ordinary course of business connected with the direct or indirect acquisition or disposal, or a possibility of disposal (whether directly or indirectly) of property (including intellectual property) having a value of 25% or more of the balance sheet value of the assets of a company determined under RAS, as well as in other cases provided by the Joint Stock Company Law.

        Consent or subsequent approval of major transactions is not required nor can be requested in the following instances:

•

the company has only one shareholder that simultaneously performs the functions of the company's CEO;



•

the transactions contemplate the placement of common stock, or securities convertible into common stock or transactions involving services provided in connection with such placements;



•

the transactions constitute transfer of assets within the framework of reorganization, in particular under merger and accession agreements;



•

the transactions are mandatory for the company pursuant to Russian law and must be concluded on the basis of fixed prices and tariffs adopted by a competent state body;



•

the transactions are public agreements which terms are similar to other public agreements executed by the company;

the transactions arising from a mandatory tender offer to purchase company's issued shares or securities convertible to shares;

•

the transactions concluded on the same terms as the preliminary contracts previously approved as major transactions.

        Major transactions involving assets having a value ranging from 25% to 50% of the balance sheet value of the assets of a company determined under RAS require unanimous approval by all members of the board of directors or, failing to receive such approval, a simple majority vote of a shareholders' meeting.

        Major transactions involving assets having a value in excess of 50% of the balance sheet value of the assets of a company determined under RAS require a three-quarters majority vote of a shareholders' meeting.

Change in Control

Anti-takeover Protection

        Russian legislation requires the following:

•

a person intending to acquire more than 30% of a public joint stock company's ordinary shares and voting preferred shares (including, for such purposes, shares already owned by such person and its affiliates)is entitled to make a public tender offer to other holders of such shares or securities convertible into such shares (the "voluntary offer");



•

a person that has acquired more than 30% of public joint stock company's ordinary shares and voting preferred shares (including, for such purposes, shares already owned by such person and its affiliates) will be required (except for certain cases) to make, within 35 days of acquiring such shares, a public tender offer in respect of other securities of the same class (the "mandatory offer"). A price for such acquisition shall not be less than a weighted average market price of

212

Table of Contents

the relevant securities over the six month period before the filing of the offer with the CBR as described below, if the securities are publicly traded, or on a price determined by an appraiser if the shares have no or less than six month trading history. In any case, the mandatory offer price may not be less than the highest price at which the offeror or its affiliated persons purchased or undertook to purchase the relevant securities over the six month period before the offer was sent to the company. From the moment of acquisition of more than 30% of the shares until the date the offer was sent to the company, the person making the offer and its affiliates will be able to register for quorum purposes and vote with only 30% of the company's ordinary shares and voting preferred shares (regardless of the size of their actual holdings). These rules also apply to acquisitions resulting in a person or a group of persons owning more than 50% and 75% of a company's issued ordinary shares and voting preferred shares;.

•

a person that as a result of a mandatory or voluntary offers becomes (individually or with its affiliates) an owner of more than 95% of the company's ordinary shares and voting preferred shares, (i) must buy out the remaining shares of the company as well as other securities convertible into such shares upon request of the holders of such shares or other securities, or (ii) may require such holders to sell such shares and other securities. The price for such acquisition shall be determined in the manner described in the preceding paragraph but not less than (i) the price of the preceding acquisition of the company's relevant securities under a mandatory or voluntary offer as a result of which the offeror and its affiliates acquired over 95% of the company's ordinary shares and voting preferred shares; or (ii) the highest price at which after the expiration date of an offer the offeror or its affiliates purchased or undertook to purchase the relevant securities;



•

acquisitions described above must be accompanied by a bank guarantee, except for an acquisition of a person holding more than 95% of the company's ordinary shares and voting preferred shares the remaining securities of the relevant type upon its request. Moreover, offers and notices regarding acquisitions described above must be filed with the CBR. The CBR may demand amendments to the terms of the offer (including a price) if they are not in compliance with the legislation;



•

once a voluntary or mandatory offer has been made, competing offers for the same securities can be made by third parties and, in certain circumstances, acceptance of the initial offer may be withdrawn by the security holders who chose to accept such competing offer;



•

generally, from the date of voluntary or mandatory offers until 20 days after its expiry the company's corporate governance shall be performed in compliance with the Joint Stock Company rules set out for these purposes. In particular, during that period it shall fall within the company's shareholders' meeting powers to make decisions on charter capital increase by issuance of new securities, approval of interested party and major (as determined for these purposes) transactions, and on certain other significant matters.

        The above rules may be amended by the CBR and it may result in a wider, narrower or more specific interpretation of these rules by the government and judicial authorities, as well as by market participants.

Approval of the FAS

        Pursuant to the Federal Law on Competition, until January 5, 2016, the FAS had to approve in advance acquisitions of voting shares in a company involving (1) companies with a combined value of assets or combined annual revenues calculated under RAS exceeding certain thresholds, or (2) companies included in a register of business entities having more than a 35% share of a certain commodity market or otherwise occupying a dominant position on the market, and which would result in acquisition by a person (or a group of affiliates) of more than 25%, 50% or 75% of voting shares of

213

Table of Contents

a joint stock company, or a participation interest according 1/3, 50%, 2/3 of voting rights in a limited liability company, or in a transfer between such companies of assets or rights to assets, the value of which exceeds a certain amount.

        According to the amendments made by the Federal law No. 275-FZ dated October 5, 2015 starting from January 5, 2016 the regulations in relation to the abovementioned register were repealed and only the combined value of assets or combined annual revenues of the companies involved in the transaction is taken in account. See also "Item 3. Key Information—D. Risk Factors—Risks Relating to Our Business—If we are found to have a dominant position in the markets where we operate and are determined to have abused this position, the FAS may be entitled to regulate our subscriber tariffs and impose certain restrictions on our operations."

Strategic Industries Law

        Pursuant to the Strategic Foreign Investment Law, investments resulting in a foreign entity or a group of entities receiving control over a company with strategic importance for the national defense and security of the Russian Federation (a "strategic company") or acquisition of fixed production assets of a strategic company having value of at least 25% of its assets calculated under RAS require prior approval from the state authorities. The procedure for issuing such consent involves a special governmental commission on control of foreign investments, which was established by the Resolution of the Government of Russia dated July 6, 2008 as the body responsible for granting such consents, and the FAS, which is authorized to process applications for consent from foreign investors. For the purposes of the Strategic Foreign Investment Law "control" means an ability to determine, directly or indirectly, decisions taken by a strategic company, whether through voting at the general shareholders' (participants') meeting of the strategic company, participating in the board of directors or management bodies of the strategic company, or acting as the external management organization of the strategic company, or otherwise. As a result, "control" will generally be deemed to exist if an entity or a group of entities acquires more than 50% of the shares (or participation interest in share capital) of a strategic company, or if through a contract or securities with voting rights it is able to appoint more than 50% of the members of the board of directors or of the management board of a strategic company.

        Furthermore, if a foreign entity or group of entities holding securities of a strategic company or other entity that exercises control over this company becomes a direct or indirect holder of voting shares in an amount that is considered to give it direct or indirect control over this company in accordance with the Strategic Foreign Investment Law due to a change in allocation of voting shares pursuant to the procedures provided by Russian law (e.g., as a result of a buy-back of its shares by the relevant company), then such entity or group of entities will have to apply for state approval of its control within three months after it received such control.

        Moreover, the Russian prime minister, who acts as President of the Commission, is entitled to impose an obligation of prior approval in regard of any transaction involving a Russian enterprise, regardless of whether such enterprise operates within a "strategic" industry or not. The decision of the Commission President has to be sent to the investor by the FAS within three business days. Upon receipt the investor will need to file the necessary application with the FAS to obtain approval. Failure to comply will result in penalties set out by the legislation.

        In addition, foreign investors are required to notify the FAS on any transactions undertaken by them resulting in the acquisition of 5% or more of the charter capital of a strategic company and other transactions or other actions preapproved in accordance with the Strategic Foreign Investment Law.

foreign shareholders, which could have a material adverse effect on our business, financial condition, results of operations and prospects."

Disclosure of Ownership

        Under Russian law, a person acquiring, directly or indirectly, 5% or more of our common shares is required to notify us and the CBR of, and we must then publicly disclose, such acquisition, as well as any subsequent acquisitions or disposals resulting in the crossing of 5%, 10%, 15%, 20%, 25%, 30%, 50%, 75% or 95% thresholds of our outstanding common shares by such person.

        A holder of more than 5% of our common shares is required to file with us and the CBR information about its controlling shareholder (if any) or notify us and the CBR about the absence of any such controlling shareholders.

        Our subsidiaries are required to notify us and the CBR about the acquisition of our common shares. We are required to publicly disclose the acquisition of our common shares by our subsidiaries.

Notification of Foreign Ownership

        Foreign persons registered as individual entrepreneurs in Russia who acquire shares in a Russian joint stock company and foreign companies that acquire shares in a Russian joint stock company may need to notify the Russian tax authorities (in case the share of direct participation exceeds 10%) within one month following such acquisition. However, the procedure for notifying the Russian tax authorities by foreign companies that are not registered with such tax authorities at the time of their share acquisition remains unclear.

Material Contracts

        The following is a description of contracts that we and/or our subsidiaries are a party to and that are or may be material to our business.

Eurobonds

        On May 28, 2013, we issued U.S. dollar-denominated Loan Participation Notes in the amount of $500 million (RUB 16.4 billion as of December 31, 2013) with an annual interest rate of 5.00% and a maturity in June 2023. The proceeds will be used for general corporate purposes. The notes were issued by MTS International Funding Limited, a private company organized and existing as a private limited company under the laws of Ireland, and are listed on the Irish Stock Exchange. Proceeds were on-lent to us pursuant to a loan agreement between us and MTS International Funding Limited.

        The loan agreements relating to our notes due 2023 sets forth various occurrences, each of which would constitute an event of default. If an event of default, other than an event of default arising from events of bankruptcy, insolvency or bankruptcy-related reorganization, occurs and is continuing, either the lender, the trustee or the holders of at least 25% in principal amount of the outstanding notes may accelerate the maturity of all of the notes. If an event of default arising from events of our bankruptcy, insolvency or bankruptcy-related reorganization occurs and is continuing, then the principal of, and accrued interest on, all of the notes will automatically become immediately due and payable without any declaration or other act on the part of the lender, holders of notes or the trustee.

        Covenants in the loan agreement relating to our notes due 2023 limit our ability to create liens on our properties, merge or consolidate with another person or convey our properties and assets to another person. In addition, if we experience certain types of mergers, consolidations or other changes in control, noteholders will have the right to require us to redeem the notes at 101% of their principal amount, plus accrued interest. If we fail to meet these covenants, after certain notice and cure periods, the noteholders can accelerate the debt to be immediately due and payable.

        On April 3, 2013, we issued exchange-traded Series 1 ruble bond on Moscow Exchange. The bond is worth RUB 10 billion and has a maturity of ten years. Coupons are to be paid semiannually at the rate of 8.25%. Bond holders will have the right under a five-year put option to sell the bonds to us. The proceeds from the bond placement were used for general corporate needs.

        On September 2, 2016, we issued RUB 10 billion exchange-traded Series 2 bonds with a maturity of 15 years and a two year put option on Moscow Exchange. Coupons are to be paid semiannually at the rate of 9.4% per annum. The proceeds from bonds were used for general corporate needs.

        On February 10, 2017 we issued RUB 10 billion exchange-traded bonds with a maturity of 5 years. Coupons are to be paid semiannually at the rate of 9.0% per annum. The proceeds from the bond placement were used for general corporate needs.

        On March 30, 2017, we placed RUB 10 billion exchange-traded bonds with a maturity of 4 years and 8.85% coupon per annum to be paid semiannually. The proceeds from bonds were used for general corporate needs.

        On December 5, 2017 we placed RUB 10 billion exchange-traded bonds with a maturity of one year and 7.70% coupon per annum. Coupons are to be paid semiannually The proceeds from bonds were used for general corporate needs.

Agreement with Apple

        In April 2017, the Group entered into an unconditional purchase agreement with Apple Rus LLC to buy 615 thousand iPhone handsets at list prices at the dates of respective purchases over a period ending June 30, 2019. Pursuant to the agreement the Group is required to incur certain iPhone advertising and promotion costs. As of December 31, 2017 the Group made 44% of its total purchase installment contemplated by the agreement.

D.  Exchange Controls

        The Federal Law on Currency Regulation and Currency Control which came into effect on June 18, 2004 sets forth certain restrictions on settlements between residents of Russia with respect to operations involving foreign securities (including ADSs), including requirements for settlement in Russian rubles.

Repatriation of Export Proceeds

        Russian companies must repatriate 100% of their receivables from the export of goods and services (with a limited number of exceptions concerning, in particular, certain types of secured financing).

Restrictions on the remittance of dividends, interest or other payments to non-residents

        The Federal Law on Foreign Investments in the Russian Federation of July 9, 1999 specifically guarantees foreign investors the right to repatriate their earnings from Russian investments. However, the evolving Russian exchange control regime may materially affect your ability to do so.

        Currently, ruble dividends on common shares may be converted into U.S. dollars without restriction. However, the ability to convert rubles into U.S. dollars is also subject to the availability of U.S. dollars in Russia's currency markets. Although there is an existing market within Russia for the

conversion of rubles into U.S. dollars, including the interbank currency exchange and over-the-counter and currency futures markets, the further development of this market is uncertain.

E.  Taxation

Certain Russian Tax Consequences

        The following discussion describes the material Russian corporate income tax and personal income tax consequences to you if you are a U.S. holder of ADSs and a resident of the United States for purposes of the United States—Russia income tax treaty and are fully eligible for benefits under the United States—Russia income tax treaty. Subject to certain provisions of the United States—Russia income tax treaty relating to limitations on benefits, a U.S. resident under the treaty is generally defined as a person liable, under the laws of the United States, to U.S. tax (other than taxes with respect to only of income from sources in the United States or capital situated therein) by reason of your domicile, residence, citizenship, place of incorporation, or any other similar criterion (and, for income derived by a partnership, trust or estate, residence is determined in accordance with the residence of the person liable to tax with respect to such income). The treaty provides for a procedure to resolve matters where a resident of the United States qualifies as a Russian tax resident under Russian domestic rules. The treaty also provides for the non-application of treaty benefits to certain types of entities.

        Additionally, the benefits under the United States—Russia income tax treaty discussed in this document generally are not available to U.S. persons who hold ADSs in connection with the conduct of a business in the Russian Federation through a permanent establishment as defined in the United States—Russia income tax treaty. Subject to certain exceptions, a U.S. person's permanent establishment under the United States—Russia income tax treaty is a fixed place of business through which such person carries on business activities in the Russian Federation (generally including, but not limited to, a place of management, a branch, an office and a factory). Under certain circumstances, a U.S. person may be deemed to have a permanent establishment in the Russian Federation as a result of activities carried on in the Russian Federation through agents of the U.S. person. This summary does not address the treatment of holders described in this paragraph.

        Treaty benefits may be potentially available to U.S. tax residents that are not subject to limitations on treaty benefits under the treaty, do not operate through a permanent establishment in Russia and are foreign legal entities (i.e., a legal entity or organization in each case not organized under Russian law) or individuals not considered Russian tax residents under Russian law. Under current Russian law, the Russian tax residency for entities is generally determined based on the place of management of this entity; for individuals is generally determined based on the number of days a person spends in Russia in a 12-month rolling period. Law specifies that an individual present in Russia for an aggregate period of 183 days in any consecutive 12-month period will be considered as a tax resident. Since tax year in Russia is a calendar year the final tax residency status of an individual taxpayer shall still be defined for a whole calendar year by counting the days spent in Russia within that relevant calendar year. Accordingly, to be considered a Russian tax resident, the taxpayer should spend at least 183 days in Russia in a calendar year. The following discussion is based on:

•

Russian tax legislation; and



•

the United States—Russia income tax treaty (and judicial and administrative interpretations thereof by the Russian authorities).

        All of the foregoing tax consequences are based on information in effect as of the date of this document and are subject to change, possibly on a retroactive basis, after the date of this document. This discussion is also based, in part, on representations of the depositary, and assumes that each obligation in the deposit agreement and any related agreements will be performed in accordance with

217

its terms. The discussion with respect to Russian legislation is based on our understanding of current Russian law and Russian tax rules, which are subject to frequent change and varying interpretations.

        The following discussion is not intended as tax advice to any particular investor. It is also not a complete analysis or listing of all potential Russian corporate income and personal income tax consequences to you of ownership of ADSs. We urge you to consult your own tax adviser regarding the specific Russian tax consequences of the ownership and disposition of ADSs under your own particular factual circumstances.

Specific uncertainties associated with the tax treatment of ADS holders

        The Russian tax rules in relation to ADS holders (that would affect U.S. holders) are characterized by significant uncertainties and limited interpretive guidance. Recent amendments to the tax rules have clarified the status of the ADS holders as beneficial owners of the income from the underlying shares by establishing that the custodian holding the depo account with the shares underlying the ADSs acting as the tax agent and determines amounts of the withholding tax based on the information about the ADS holders and their tax residency status as provided by the program depositary. However, the application of the baseline tax rate for ADS holders and any double tax treaty relief is available only if the tax treaty residence of the holder is provided to the custodian along with the other information prescribed by the Tax Code. In relation to ADS holders such information is to be provided by the ADS holders to the depositary, who relays it to the custodian, who acts as the tax agent and withholds the taxes when making transferring the dividends to the depositary. It is currently unclear how the depositary will collect the necessary information from ADS holders. Thus, while a U.S. holder may technically be entitled to benefit from the provisions of the United States—Russia income tax treaty, in practice such relief may be difficult or impossible to obtain.

        Russian tax law and procedures are also not well developed, and local tax inspectors have considerable autonomy and often interpret tax rules without regard to the rule of law. Both the substantive provisions of Russian tax law and the interpretation and application of those provisions by the Russian tax authorities may be subject to more rapid and unpredictable change than in jurisdictions with more developed capital markets.

Taxation of Dividends

        Dividends paid to U.S. holders generally will be subject to Russian withholding tax at a 15% rate. The tax burden may be reduced to 5% or 10% under the United States—Russia income tax treaty for eligible U.S. holders; a 5% rate may potentially apply for U.S. holders who are legal entities owning 10% or more of the company's voting shares, and a 10% rate applies to dividends paid to eligible U.S. holders in other cases, including dividend payments to individuals and legal entities owning less than 10% of the company's voting shares. Reduced tax rates may apply in case the information, required by the Russian Tax code, is presented to the tax agent fully and in time; otherwise, the tax agent is required to use the baseline tax rate established by the code, or tax rate set by the applicable tax treaty, not taking into account the percentage of share in Charter Capital, the amount of investment, or term of ownership, whichever is appropriate. See also "—United States—Russia Income Tax Treaty Procedures."

        From a practical perspective, it may have not been possible for the depositary to collect the necessary information from all ADS holders and submit the relevant information to the custodian. Therefore, with respect to legal entities or organizations who are U.S. holders, the custodian may be obligated to withhold income tax at a rate of 15% from dividend payments made to the trustee, unless the information on the ADS holder, the respective amount of ADS held and its tax residency is provided to the depositary and thereafter to the custodian within 7 days of the date on which the shareholders entitled to dividend payout are determined according the relevant decision of the general

218

Table of Contents

shareholders meeting. The same amendments have also introduced an expedited refund process whereby the information regarding the ADSs not provided to the custodian can be submitted within 25 days of the date of the payment of the dividends to the depositary in order for the custodian to refund the difference between the increased 15% tax rate used and the tax rate the respective ADS holders are entitled to according to their tax residency, however this process is new and not tested and it is unclear how it will work in practice. Although non-resident holders of ADSs may apply for a refund of a portion of the tax withheld under an applicable tax treaty, the procedure to do so may be time consuming and no assurance can be given that the Russian tax authorities will grant a refund. See "—United States—Russia Income Tax Treaty Procedures."

        If the appropriate information is not provided to the depositary for transfer to the custodian in a timely manner, the custodian may have to withhold tax at the 15% rate, and U.S. holders that are legal entities qualifying for a reduced rate under the United States—Russia income tax treaty then may file claims for a refund within three years with the Russian tax authorities.

        With respect to individuals who are U.S. holders of ADSs and who are Russian tax non-residents, the custodian may also be obligated to withhold income tax at the rate of 15% from dividend payments made to the depositary. Similarly to the order applicable to legal entities, reduced tax rates may apply in case the information, required by the Russian Tax Code, is presented to the tax agent fully and in time; otherwise, the tax agent is required to use the baseline tax rate established by the code, or tax rate set by the applicable tax treaty, not taking into account the percentage of share in Charter Capital, the amount of investment, or term of ownership, whichever is appropriate. Where withholding of personal income tax is not performed, individuals who are U.S. holders of ADSs will then be required to submit an annual personal tax return to the Russian tax authorities and pay Russian income tax at a rate of 15% as under Russian law an individual should report on his or her tax liabilities in case the relevant tax was due but not withheld by a tax agent from the relevant payment. When submitting the tax return, individuals who are U.S. holders may claim an application of the reduced rates of withholding tax established by the relevant treaty, provided that the procedures described in "—United States—Russia Income Tax Treaty Procedures" are complied with. Obtaining the respective approvals from the tax authorities may be time-consuming and burdensome.

        For individuals claiming treaty relief, the documents substantiating the right for treaty benefits should be submitted to the Russian tax authorities within one year after the end of the year to which these benefits relate. In practice, where withholding is performed, the tax authorities may refuse to refund or credit the 15% tax withheld from payment of dividends to the depositary and, therefore, it is possible that individuals who are U.S. holders may be subject to up to a 30% effective tax rate (general tax rate for Russian tax non-residents) on their share of dividends.

        The amendments to the Russian Tax Code, which came into effect from January 1, 2015, exclude dividends from the scope of payments subject to 30% withholding tax rate.

Taxation of Capital Gains

Legal entities and Organizations

        Income received by a foreign company from the sale, exchange or other disposal (assuming that such income is not related to a permanent establishment of a foreign company in Russia) of shares (participation interest) in an organization in which over 50% of the assets consist of immovable property located in Russia, as well as financial instruments derived from such shares, is treated as income derived from a source in the Russian Federation and is subject to withholding tax at a rate of 20%. However, gains arising from the disposition of the securities which are traded on an organized stock exchange are not treated as Russian-source income, and should not be subject to taxation in Russia.

219

---

Table of Contents

        The amount of such income is typically determined as the sales price of shares (participation interest). However, if documentary support for the acquisition cost of the shares (participation interest) is available, the tax may instead be assessed on the basis of the difference between the sales price and the acquisition cost (including other related costs) if documentary evidence of such costs is submitted to the tax agent. The Russian Tax Code also establishes special rules for calculating the tax base for the purposes of transactions with securities. However, an exemption applies if immovable property located in Russia constitutes more than 50% of our assets and the securities are traded on a foreign stock exchange. The determination of whether more than 50% of our assets consist of immovable property located in Russia is inherently factual and is made on an on-going basis and the relevant Russian legislation and regulations in this respect are not entirely clear. Hence, there can be no assurance that immovable property owned by us and located in Russia does not currently and will not constitute more than 50% of our assets as at the date of the sale of ADSs by non-residents.

        Where the ADSs are sold by legal entities or organizations to persons other than a Russian company or a foreign company or an organization with a registered permanent establishment in Russia, even if the resulting capital gain is considered taxable in Russia, there is currently no mechanism under which the purchaser will be able to withhold the tax and remit it to the Russian budget.

        Under the United States—Russia income tax treaty, capital gains from the sale of shares and/or ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the treaty) were to consist of immovable property located in Russia.

Individuals

        The taxation of the income of tax non-resident individuals depends on whether this income is received from Russian or non-Russian sources. Russian tax law considers the place of sale as an indicator of source. Accordingly, the sale of securities outside of Russia by individuals who are non-resident holders should not be considered Russian source income and, therefore, should not be taxable in Russia. However, Russian tax law gives no clear indication as to how the place of sale of securities should be defined in this respect. Therefore, the Russian tax authorities may have a certain amount of flexibility in concluding whether a transaction is in Russia or out of Russia.

        The sale, exchange or other disposal of the shares and ADSs by non-resident individual holders in Russia will be considered Russian source income and will be subject to tax at a rate of 30% on the difference between the sales price and the acquisition costs of such securities, as well as other documented expenses, such as depositary expenses and broker fees, among others, defined by the tax rules.

        Under Russian law, the acquisition costs and related expenses can be deducted at the source of payment if the sale was made by a non-resident holder through a licensed Russian broker, trust manager or other person that carries out operations under agency or commission agreements, or other agreements in favor of a taxpayer. Such party (as defined above) should also act as a tax agent and withhold the applicable tax. Such tax agent will be required to report to the Russian tax authorities the amount of income realized by the non-resident individual and tax withheld upon the sale of the securities.

        Otherwise, if the sale is made to individuals but not through a tax agent, generally no withholding needs to be made and the non-resident holder will have an obligation to file a tax return, report his income realized and apply for a deduction of acquisition expenses (which includes filing of support documentation). Although Russian tax law imposes tax agent responsibility only on professional trustees, brokers or dealers, in practice, the tax authorities may require Russian legal entities and organizations or foreign companies with any registered presence in Russia that are not professional

220

Table of Contents

trustees, dealers or brokers to act as tax agents and withhold the applicable tax when purchasing securities from non-resident individuals.

        Under the United States—Russia income tax treaty, capital gains from the sale of the ADSs by eligible U.S. holders should be relieved from taxation in Russia, unless 50% or more of our assets (the term "fixed assets" is used in the Russian version of the United States—Russia Tax Treaty) were to consist of immovable property located in Russia. If this 50% threshold is not met, individuals who are U.S. holders may seek to obtain the benefit of the United States—Russia income tax treaty in relation to capital gains resulting from the sale, exchange or other disposition of the ADSs.

        In order to apply the provisions of relevant double tax treaties, the individual holders should receive clearance from the Russian tax authorities as described below. See "—United States—Russia Income Tax Treaty Procedures" below.

United States—Russia Income Tax Treaty Procedures

        The Russian Tax Code does not contain a requirement that a non-resident holder that is a legal entity or organization must obtain tax treaty clearance from the Russian tax authorities prior to receiving any income in order to qualify for benefits under an applicable tax treaty. However, a non-resident legal entity or organization seeking to obtain relief from or reduction of Russian withholding tax under a tax treaty must provide to a Russian company or foreign company or organization acting through its Russian registered presence, which is a tax agent (i.e., the entity paying income to a non-resident) a confirmation of its tax treaty residence that complies with the applicable requirements and a Russian translation attached to it in advance of receiving the relevant income. The tax residency confirmation needs to be renewed on an annual basis and provided to the payer of income before the first payment of income in each calendar year. Starting from 2017, in order to benefit from the tax treaty the recipient of passive income has to provide a confirmation that it is the beneficial owner of this income.

        A U.S. holder may obtain the appropriate certification by mailing completed forms, together with the holder's name, taxpayer identification number, the tax period for which certification is required, and other applicable information, to the United States Internal Revenue Service. The procedures for obtaining certification are described in greater detail in the instructions to Internal Revenue Service Form 8802. As obtaining the required certification from the Internal Revenue Service may take at least six to eight weeks, U.S. holders should apply for such certification as soon as possible.

        In accordance with the Russian Tax Code, to rely on tax treaty benefits, a non-resident holder who is an individual must present to the tax authorities an official document confirming his residency in the home country issued by the competent authorities in his/her country of residence and also other supporting documentation including a statement confirming the income received and the tax paid in the home country, also confirmed by the relevant foreign tax authorities, duly translated and apostilled or pass through a consular legalization. Technically, such a requirement means that an individual cannot rely on the tax treaty until he or she pays the tax in the jurisdiction of his or her residence. Therefore, advance relief from or reduction of withholding taxes for individuals will generally be impossible as it is very unlikely that the supporting documentation for the treaty relief can be provided to the tax authorities and approval from the latter obtained before any payments are made to individuals. A non-resident holder which is an individual may apply for treaty-based benefits and claim tax refund within three years following the end of the tax period in which the relevant income was received and the tax was withheld.

        If a non-resident holder which is a legal entity or organization does not obtain double tax treaty relief at the time that income or gains are realized and tax is withheld by a Russian tax agent, the non-resident holder may apply for a refund within three years from the end of the tax period (a calendar year) in which the tax was withheld. To process a claim for a refund, the Russian tax

Table of Contents

authorities require (i) apostilled or legalized confirmation of the tax treaty residence of the non-resident at the time the income was paid, (ii) an application for the refund of the tax withheld in a format provided by the Russian tax authorities and (iii) copies of the relevant contracts under which the foreign entity received income, as well as payment documents confirming the payment of the tax withheld to the Russian budget (Form 1012DT for dividends and interest and Form 1011DT for other income are designed by the Russian tax authorities to combine requirements (i) and (ii) specified above). The Russian tax authorities may require a Russian translation of the above documents if they are prepared in a foreign language. The refund of the tax withheld should be granted within one month of the filing of the above set of documents with the Russian tax authorities. However, procedures for processing such claims have not been clearly established and there is significant uncertainty regarding the availability and timing of such refunds.

        Recent amendments to the Russian Tax Code have established additional requirements to the reimbursement procedure referred to above, identifying further documents that need to be provided to the tax authorities. These include: 1) a document confirming the rights of the ADS holder to the ADS as of the date on which the shareholders entitled to the dividend payout are set according to the relevant decision of the General shareholders meeting, 2) a document evidencing the actual amount of income received by the ADS holder, 3) a document with information about the custodian that transferred the dividend amounts to the depositary, and 4) documents confirming the ADS holder's compliance with the requirements of the Tax Code and/or the relevant income tax treaty provisions necessary for application of a reduced rate. The above requirements refer not only to ADS, but also to securities in general. In addition to the documents listed above, tax authorities may require more information and documents. Decision on refund is to be taken by the tax authorities within six months. The procedures referred to above are new and no assurance can be given that the custodian will be able to apply the respective double tax treaties when paying dividends to non-resident holders or that ADS holders would be successful in receiving relevant tax refunds.

        Neither the depositary nor us has or will have any obligation to assist an ADS holder with the completion and filing of any tax forms.

Certain United States Federal Income Tax Consequences

        The following is a general description of certain material United States federal income tax consequences that apply to you if you are, for United States federal income tax purposes, a beneficial owner of ADSs that is an individual who is a citizen or resident of the United States, a corporation created or organized in or under the laws of the United States, any state thereof or the District of Columbia, an estate the income of which is subject to U.S. federal income tax regardless of its source, or a trust, if a United States court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if the trust has a valid election in effect under applicable U.S. Treasury Regulations to be treated as a United States person (in each case, a "U.S. Holder"). This discussion is based on the Internal Revenue Code of 1986, as amended (the "Code"), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the Internal Revenue Service ("IRS"), all as publicly available and in effect as of the date of this document. These authorities are subject to differing interpretations and may change, possibly retroactively, resulting in U.S. federal income tax consequences different from those discussed below. No ruling has been or will be sought from the IRS with respect to the matters discussed below, and there can be no assurance that the IRS will not take a contrary position regarding the tax consequences of the acquisition, ownership or disposition of ADSs, or that any such contrary position would not be sustained by a court. If an entity treated as a partnership for United States federal income tax purposes is an owner of ADSs, the United States federal income tax treatment of a partner in the partnership will generally depend on the status of the partner and the activities of the partnership. Accordingly, partnerships that hold ADSs and partners in

222

Table of Contents

such partnerships are urged to consult their tax advisors regarding the specific U.S. federal income tax consequences to them. The following discussion does not deal with the tax consequences to any particular investor or to persons in special tax situations such as:

•

an insurance company;



•

a tax-exempt organization;



•

a financial institution;



•

a person subject to the alternative minimum tax;



•

a person who is a broker-dealer in securities or a trader subject to a mark-to-market election;



•

an S corporation;



•

a partnership, a pass-through entity, a person holding ADSs through a partnership or other pass-through entity;



•

an expatriate subject to section 877 of the Code;



•

a holder that is not a U.S. Holder;



•

an investor that has a functional currency other than the U.S. dollar;



•

a person subject to special tax accounting rules as a result of any item of gross income with respect to the shares or ADSs being taken into account in an applicable financial statement;



•

a regulated investment company;



•

a real estate investment trust;



•

an owner of, directly, indirectly or by attribution, 10% or more of the outstanding shares of our stock (by vote or value); or



•

an owner holding ADSs as part of a hedge, straddle, synthetic security or conversion transaction.

        In addition, this summary is limited to U.S. Holders holding ADSs as "capital assets" within the meaning of Section 1221 of the Code and whose functional currency is the U.S. dollar. The discussion below does not address the effect of the Medicare tax on "net investment income" or of any United States state or local tax law or foreign tax law. This discussion also does not address any tax consequences relating to the direct ownership of ordinary shares.

        The discussion below assumes that the representations contained in the deposit agreement are true and that the obligations in the deposit agreement and any related agreement will be complied with in accordance with their terms. For purposes of applying United States federal income tax law, we believe, and the following discussion assumes, that a holder of an ADS should be treated as the owner of the underlying shares of common stock represented by that ADS, although this matter is not free from doubt.

        The U.S. Treasury has expressed concerns that intermediaries in the chain of ownership between the holder of an ADS and the issuer of the shares underlying the ADS may be taking actions that are inconsistent with the beneficial ownership of the underlying shares. Accordingly, the analysis of the creditability of Russian withholding taxes described below and the availability of the reduced tax rate for dividends received by certain non-corporate U.S. Holders (discussed below) could be affected by actions taken by intermediaries in the chain of ownership between the holder of ADSs and our company if as a result of such actions the holders of ADSs are not properly treated as beneficial owners of underlying shares and future actions that may be taken by the U.S. Treasury. The remainder of this discussion assumes that a holder of an ADS will be treated as the beneficial owner of the underlying shares of common stock represented by such ADS for United States federal income tax purposes.

Taxation of Distributions on ADSs

        Subject to the passive foreign investment company rules described below, for United States federal income tax purposes, the gross amount of a distribution, including any Russian withholding taxes, paid by us with respect to ADSs will be treated as a taxable foreign source dividend on the date of actual or constructive receipt by the depositary to the extent of our current and accumulated earnings and profits, computed in accordance with United States federal income tax principles. If you are a non-corporate U.S. Holder such dividends may be "qualified dividend income" that is taxed at the lower applicable capital gains rate provided that certain conditions are satisfied, including (1) certain holding period requirements are satisfied, (2) either (a) our ADSs continue to be listed on the New York Stock Exchange (or other national securities exchange that is registered under section 6 of the Securities Exchange Act of 1934, as amended, or the Nasdaq Stock Market) or (b) we are eligible for the benefits of the United States—Russia income tax treaty, and (3) we are not, for the taxable year in which the dividend was paid, or in the preceding taxable year, a "passive foreign investment company" with respect to your ADSs (as discussed below). Distributions with respect to ADSs in excess of our current and accumulated earnings and profits will be applied against and will reduce your tax basis in such ADSs and, to the extent in excess of such tax basis, will be treated as gain from a sale or exchange of such ADSs. You should be aware that we do not intend to calculate our earnings and profits for United States federal income tax purposes and, unless we make such calculations, you should assume that any distributions with respect to ADSs generally will be treated as a dividend, even if such distributions would otherwise be treated as a return of capital or as capital gain pursuant to the rules described above. If you are a corporation, you will not be allowed a deduction for dividends received in respect of distributions on ADSs, which is generally available for dividends paid by U.S. corporations. U.S. Holders are strongly urged to consult their tax advisors as to the U.S. federal income tax treatment of any distribution received with respect to ADSs.

        The amount of any distribution paid in rubles will equal the U.S. dollar value of such rubles, calculated using the exchange rate in effect on the date of actual or constructive receipt by the depositary, regardless of whether the payment is actually converted into U.S. dollars. Generally, any gain or loss resulting from currency exchange rate fluctuations during the period from the date of receipt by the depositary to the date the rubles are converted into U.S. dollars will be treated as ordinary income or loss from sources within the United States for foreign tax credit limitation purposes. Additionally, you may be required to recognize foreign currency gain or loss on the receipt of a refund of Russian withholding tax pursuant to the United States—Russia income tax treaty to the extent the United States dollar value of the refund differs from the dollar equivalent of that amount on the date of receipt of the underlying distribution.

        Russian withholding tax at the rate applicable to you under the United States—Russia income tax treaty should be treated as a foreign income tax that, subject to generally applicable limitations and conditions, may be eligible for credit against your U.S. federal income tax liability or, at your election, may be deducted in computing taxable income. If Russian tax is withheld at a rate in excess of the rate applicable to you under the United States—Russia income tax treaty, you may not be entitled to credits for the excess amount, even though the procedures for claiming refunds and the practical likelihood that refunds will be made available in a timely fashion are uncertain. If the dividends are qualified dividend income (as discussed above), the amount of the dividend taken into account for purposes of calculating the foreign tax credit limitation will generally be limited to the gross amount of the dividend, multiplied by the reduced rate divided by the highest rate of tax normally applicable to dividends.

        The limitation on foreign taxes eligible for credit is calculated separately with respect to specific classes of income. For United States foreign tax credit purposes, a dividend distribution with respect to the ADSs will be treated as foreign source "passive category income." The rules relating to the

224

---

Table of Contents

determination of the foreign tax credit, or deduction in lieu of the foreign tax credit, are complex and you should consult your tax advisors with respect to those rules.

Taxation on Sale or Other Taxable Disposition of ADSs

        Subject to the passive foreign investment company rules described below, the sale or other taxable disposition of ADSs will generally result in the recognition of gain or loss in an amount equal to the difference between the amount realized on the sale or other taxable disposition and your adjusted basis in such ADSs. That gain or loss will be capital gain or loss and will be long-term capital gain or loss if you have held the ADSs for more than one year. If you are a non-corporate U.S. Holder, such recognized long-term capital gain is generally subject to a reduced rate of United States federal income tax. Limitations may apply to your ability to offset capital losses against ordinary income.

        Gain or loss recognized on the sale of ADSs will generally be treated as U.S. source income or loss for foreign tax credit purposes. The use of any foreign tax credits relating to any Russian taxes imposed upon such sale may be limited. You are strongly urged to consult your tax advisors as to the availability of tax credits for any Russian taxes withheld on the sale of ADSs.

Passive Foreign Investment Company Considerations

        A non-U.S. corporation generally will be a passive foreign investment company (a "PFIC"), in any taxable year in which, after taking into account the income and assets of the corporation and certain subsidiaries pursuant to applicable "look-through" rules, either (i) at least 75% of its gross income is "passive income" or (ii) at least 50% of the average value of its assets is attributable to assets which produce passive income or are held for the production of passive income.

        We do not believe that we were a PFIC for the year ended December 31, 2015. However, our possible status as a PFIC must be determined annually and may be dependent in part on the market price of our ADSs, which may be volatile. Therefore, our possible status as a PFIC may be subject to change. Thus there can be no assurance that we will not be treated as a PFIC in our current taxable year or in the future. If we were to be treated as a PFIC, U.S. Holders generally would be required to pay additional taxes on certain distributions and gains on sales or other dispositions (including pledges) of the ADSs, at tax rates that may be higher than those otherwise applicable. You should consult your tax advisors regarding the application of the PFIC rules to your investment in the ADSs.

Information Reporting and Backup Withholding

        Dividend payments with respect to ADSs and proceeds from the sale or exchange of ADSs may be subject to information reporting to the IRS and possible U.S. backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes any other required certification or who is otherwise exempt from backup withholding. U.S. Holders who are required to establish their exempt status generally must provide such certification on IRS Form W-9. U.S. Holders should consult their tax advisors regarding the application of the U.S. information reporting and backup withholding rules.

        Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against your U.S. federal income tax liability, and you may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

Additional Reporting Requirements

        Certain U.S. Holders who are individuals may be required to report information relating to an interest in the ADSs, subject to certain exceptions (including an exception for ADSs held in accounts

225

---

Table of Contents

maintained by certain financial institutions). U.S. Holders should consult their tax advisors regarding the effect, if any, of this requirement on their ownership and disposition of the ADSs.

FATCA

        Provisions under Sections 1471 through 1474 of the Code and applicable U.S. Treasury Regulations commonly referred to as "FATCA" generally impose 30% withholding on certain "withholdable payments" and, in the future, may impose such withholding on "foreign passthru payments" made by a "foreign financial institution" (each as defined in the Code) that has entered into an agreement with the IRS to perform certain diligence and reporting obligations with respect to the foreign financial institution's U.S.-owned accounts. Prospective investors should consult their tax advisors regarding the potential impact of FATCA and any non-U.S. legislation implementing FATCA on the investment in ADSs.

Item 11.    Quantitative and Qualitative Disclosures about Market Risk

        We are exposed to market risk from changes in interest rates and foreign currency exchange rates. We are subject to market risk deriving from changes in interest rates, which may affect the cost of our financing. Foreign exchange risks exist to the extent our revenues, costs and debt obligations are denominated in currencies other than the functional currency in the countries of our operations.

Interest Rate Risk

        We are exposed to variability in cash flow risk related to our variable interest rate debt and exposed to fair value risk related to our fixed-rate notes. As of December 31, 2017, RUB 28,409 million, or 9.70% of our total indebtedness, excluding capital leases, was variable interest rate debt, while RUB 264,378 million, or 90.30% of our total indebtedness, excluding capital leases, was fixed interest rate debt.

        The table below presents principal cash flows and related weighted average interest rates for indebtedness by contractual maturity dates as of December 31, 2017.

Table of Contents

Contractual Maturity Date as of December 31, 2017:

        We would have experienced an additional interest expense of approximately RUB 44 million on an annual basis as a result of a hypothetical increase in variable rates by 1% over the current rate as of December 31, 2017. The rates of EUR and USD as of December 31, 2017 were used in calculations.

        The fair value of our publicly traded fixed-rate notes as of December 31, 2017, ranged from 99.59% to 112.05% of the notional amount. As of December 31, 2017, the difference between the carrying value and the fair value of other fixed rate debt, including capital lease obligations, was immaterial. For details of our fixed-rate debt, refer to Note 15 of our audited consolidated financial statements. The fair value of variable rate debt approximates its carrying value.

        We use derivative financial instruments to eliminate the exposure of changes in value of debt obligations. We primarily focus on reducing risk caused by the fluctuations in value for our fixed-rate long-term debt. According to our policy, we have entered into various fixed-to-variable interest rate

227

swap agreements. The table below presents a summary of our fixed-to-variable interest rate swap agreements.

        As of December 31, 2017, approximately 7.9% of our fixed interest rate debt was hedged against risks of changes in value of the debt. We continue to consider other financial instruments available to us to mitigate exposure to debts' value fluctuations.

        We also use derivative financial instruments to reduce our exposure to adverse fluctuations in interest rates. We primarily focus on reducing risk caused by the fluctuations in interest rates for our variable-rate long-term debt. According to our policy, we have entered into several cross-currency interest rate swap agreements. These contracts, which hedge the risk of both interest rate and currency fluctuations, assume periodical exchanges of both principal and interest payments from ruble-denominated amounts to U.S. dollar-denominated amounts, to be exchanged at specified rates. The rates were determined with reference to the market spot rates upon issuance. These contracts also include an interest rate swap of a variable U.S. dollar-denominated interest rate to a fixed ruble-denominated interest rate. All of our cross-currency interest rate swaps agreements mature in 2019, 2020 and 2024.

Ukraine. These rates may differ from the actual rates used in preparation of our financial statements and other financial information provided herein.

        The exchange rate between the hryvnia and the U.S. dollar quoted by the National Bank of Ukraine for April 27, 2018 was 26.23 hryvnias per U.S. dollar.

        We have exposure to fluctuations in the value of the U.S. dollar relative to the Russian ruble, Ukrainian hryvnia, Turkmen manat and Armenian dram which are the functional currencies in our countries of operation. As a result, we may face translation losses, increased debt service payments and increased capital expenditures and operating costs should these currencies depreciate against the U.S. dollar

        A significant part of our capital expenditures, borrowings and certain operating costs (roaming expenses, cost of customer equipment and other costs) are either denominated in U.S. dollars or tightly linked to the U.S. dollar exchange rate, and our U.S. dollar-denominated debt represents our primary future risk of exchange loss in U.S. dollar terms. A decline in the value of the ruble, hryvnia, manat, dram or sum versus the U.S. dollar would result in currency remeasurement losses as the amount of these currencies required to repay U.S. dollar-denominated debt increases. In addition, if any of the ruble, hryvnia, manat or dram declines against the U.S. dollar and tariffs cannot be maintained for competitive or other reasons, our revenues and operating margins could be materially adversely affected and we could have difficulty repaying or refinancing our U.S. dollar-denominated indebtedness and financing our capital expenditures and operating costs.

        A portion of our capital expenditures, borrowings and certain operating costs (roaming expenses, costs of customer equipment and other costs) are also denominated in euros. We currently do not hedge against the risk of decline in the ruble, hryvnia, manat, dram or sum against the euro because settlements denominated in euros are not significant.

We would experience a currency exchange gain of RUB 830 million in the fair value of our euro-denominated net monetary liabilities as a result of a hypothetical 5.0% increase in the ruble/hryvnia/manat/dram to euro exchange rate at December 31, 2017.

Item 15.    Controls and Procedures

(a)

Disclosure Controls and Procedures.

        As of the end of the period covered by this Annual Report on Form 20- F, we carried out an evaluation, under the supervision and with the participation of our management, including our CEO and CFO, of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934).

        Based on this evaluation, our CEO and CFO concluded that our disclosure controls and procedures are effective, as of December 31, 2017, to provide reasonable assurance that the information required to be disclosed in filings and submissions under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions about required disclosure.

        There are inherent limitations to the effectiveness of any system of disclosure controls and procedures, including the possibility of human error and the circumvention or overriding of the controls and procedures. Accordingly, even effective disclosure controls and procedures can only provide reasonable assurance of achieving their control objectives.

(b)

Management's annual report on internal control over financial reporting.

        Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system was designed to provide reasonable assurance to our management and board of directors regarding the reliability of financial reporting and the preparation of financial statements for external purposes in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

        Internal control over financial reporting refers to a process designed by, or under the supervision of, our Chief Executive Officer and Chief Financial Officer and effected by our board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board and includes those policies and procedures that:

•

Pertain to the maintenance of records that in reasonable details accurately and fairly reflect the transactions and dispositions of our assets:



•

Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board, and that our receipts and expenditures are being made only in accordance with authorizations of our management and members of our board of directors;

235

---

Table of Contents

•

Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of our assets that could have a material effect on our financial statements.

        Management evaluated the effectiveness of our internal control over financial reporting as of December 31, 2017 based on the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission, or COSO, in Internal Control—Integrated Framework (2013).

        As a result of management's evaluation of our internal control over financial reporting, management concludes that internal control over financial reporting as of December 31, 2017 was effective.

        The effectiveness of our internal control over financial reporting as of December 31, 2017 has been audited and assessed as effective by independent registered public accounting firm Deloitte & Touche CIS, who has also audited and reported on our consolidated financial statements.

        There were no changes in our internal control over financial reporting during the year ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect our internal control over financial reporting.

Attestation Report of Independent Registered Public Accounting Firm.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

        To the Board of Directors and Shareholders of Mobile TeleSystems:

        Opinion on Internal Control over Financial Reporting

        We have audited the internal control over financial reporting of Mobile TeleSystems and subsidiaries (the "Group") as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Group maintained, in all material respects, effective internal control over financial reporting as of Desember 31, 2017, based on the criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

        We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated financial statements as of and for the year ended December 31, 2017, of the Group and our report dated March 19, 2018 expressed an unqualified opinion on those financial statements.

        Basis for Opinion

        The Group's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Included in the accompanying management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Group's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Group in accordance with the U. S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other

236

Table of Contents

procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        Definition and Limitations of Internal Control over Financial Reporting

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with International Financial Reporting Standards as issued by the International Accounting Standards Board, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that the controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Item 16F.    Change in Registrant's Certifying Accountant

        Not applicable.

Item 16G.    Corporate Governance

        We are a company organized under the laws of the Russian Federation and qualify as a foreign private issuer as such term is defined in Rule 3b-4 of the Exchange Act. In accordance with the NYSE corporate governance rules, listed companies that are foreign private issuers are permitted in some circumstances to follow home country practice in lieu of the provisions of the corporate governance rules contained in Section 303A of the NYSE Listed Company Manual that are applicable to U.S. companies. In addition, foreign private issuers listed on the NYSE must disclose any significant ways in which their corporate governance practices differ from those followed by U.S. companies listed on the NYSE. With regard to our corporate governance practices, these differences can be summarized as follows:

•

For U.S. companies, the NYSE standards require that a majority of directors be independent, as determined by the board. Russian law does not require that a majority of our directors be independent. Of our nine directors, four have been determined by the board to be independent in accordance with the independence standards set forth in SEC Rule 10A-3 and Section 303A.02 of the NYSE Listed Company Manual.



•

For U.S. companies, the NYSE standards require that the audit committee have a minimum of three members. Russian law does not contain such a requirement. Our audit committee comprises of three members.



•

For U.S. companies, the NYSE standards require that non-management directors meet at regularly scheduled executive sessions without management. Russian law does not contain such a requirement. However, our audit committee and remuneration and nomination committee comprises of independent directors, who meet on a regular basis in connection with their work on these committees.



•

For U.S. companies, the NYSE standards require that listed companies have a nominating/corporate governance committee and a compensation committee, each composed entirely of independent directors and having a written charter specifying the committee's purpose and responsibilities, as well as annual performance evaluations of the committee.

        We have a corporate governance committee comprising of directors and members of management that is responsible for developing and implementing standards for corporate governance and making

240

---

Table of Contents

recommendations to the Board of Directors on developing our strategy in the area of corporate governance.

        We have a remuneration and nomination committee comprising of four independent directors. This committee functions pursuant to bylaws approved by the Board of Directors specifying the committee's purpose, duties and responsibilities. The committee is primarily responsible for recommending appointments to key managerial posts, developing a set of requirements and criteria for directors and management executives and developing a remuneration structure and compensation levels for the Board of Directors, the audit committee and management executives (including the CEO). This committee is also responsible for conducting annual performance evaluations of the Board of Directors.

•

For U.S. companies, the NYSE standards require that shareholders be given the opportunity to vote on all equity compensation plans and material revisions. Under Russian law, such approval from shareholders is not required, and our equity compensation plans and material revisions thereto are currently approved by the Board of Directors.



•

For U.S. companies, the NYSE standards require the adoption and disclosure of corporate governance guidelines addressing certain subjects. Our corporate governance guidelines are consistent with what is required under Russian law and are set forth in our Charter, in the bylaw on our Board of Directors and in the bylaws of our various committees.

        We are required under the New York Stock Exchange listing rules to disclose any significant differences between the corporate governance practices that we follow under Russian law and applicable listing standards and those followed by U.S. domestic companies under New York Stock Exchange listing standards. This disclosure is posted on our website (http://www.mtsgsm.com/information/corporate_governance/).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of Mobile TeleSystems PJSC:

Opinion on the Financial Statements

        We have audited the accompanying consolidated statements of financial position of Mobile TeleSystems PJSC and subsidiaries (the "Group") as of December 31, 2017 and 2016, the related consolidated statements of profit or loss, comprehensive income, changes in shareholders' equity, and cash flows, for each of the three years in the period ended December 31, 2017, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of Mobile TeleSystems PJSC and subsidiaries as of December 31, 2017 and 2016, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2017, in conformity with International Financial Reporting Standards as issued by the International Accounting Standards Board.

        We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Group's internal control over financial reporting as of December 31, 2017, based on criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 19, 2018 expressed an unqualified opinion on the Group's internal control over financial reporting.

Basis for Opinion

        These consolidated financial statements are the responsibility of the Group's management. Our responsibility is to express an opinion on the Group's consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Group in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

        We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

(Amounts in millions of Russian Rubles unless otherwise stated)

1. GENERAL INFORMATION AND DESCRIPTION OF BUSINESS

        Public Joint-Stock Company Mobile TeleSystems ("MTS PJSC", or "the Company") is a company incorporated under the laws of the Russian Federation and having its registered address at 4, Marksistskaya Street, 109147, Moscow, Russian Federation.

        The consolidated financial statements of the Company and its subsidiaries ("the Group" or "MTS") as of December 31, 2017 and 2016, and for the years ended 31 December 2017, 2016 and 2015 were authorized for issue by MTS President on March 19, 2018.

        Business of the Group—MTS PJSC was incorporated on March 1, 2000, through the merger of MTS CJSC and Rosico TC CJSC, its wholly-owned subsidiary. MTS CJSC started its operations in the Moscow license area in 1994 and then began expanding through Russia and the CIS. MTS PJSC's majority shareholder is Public Joint-Stock Financial Corporation Sistema or Sistema, whose controlling shareholder is Vladimir P. Yevtushenkov.

        The Group provides a wide range of telecommunications services including voice and data transmission, internet access, pay TV, various value added services ("VAS") through wireless and fixed lines, integration services as well as selling equipment, accessories and software. The Group's principal operations are located in Russia, Ukraine and Armenia.

        MTS completed its initial public offering in 2000 and listed its shares of common stock, represented by American Depositary Shares, or ADSs, on the New York Stock Exchange under the symbol "MBT". Since 2003 common shares of MTS PJSC have been traded on the Public Joint-Stock Company "Moscow Exchange MICEX-RTS" ("Moscow Exchange").

        Since 2009, the Group has been developing its own retail network, operated by Russian Telephone Company CJSC ("RTC"), a wholly owned subsidiary of MTS PJSC.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS

        Basis of preparation—These consolidated financial statements were prepared in accordance with International Financial Reporting Standards ("IFRS") as issued by the International Accounting Standards Board ("IASB").

        These consolidated financial statements are prepared on a historical cost basis, unless disclosed otherwise. Historical cost is generally based on the fair value of the consideration given in exchange for goods and services.

        Amounts in the consolidated financial statements are stated in millions of Russian Rubles ("RUB million"), unless indicated otherwise.

        These consolidated financial statements have been prepared on the assumption that the Group is a going concern and will continue in operation for the foreseeable future.

        Basis of consolidation—The consolidated financial statements incorporate the financial statements of the Company and entities controlled by the Company. Control is achieved only where the Company has the power over the entity, is exposed and has rights to variable returns, and is able to use the power to affect its amount of variable returns. The results of the controlled entities acquired or

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

disposed of during the reporting period are included in the consolidated financial statements from the date, the Group achieves control over the entity, or until the date on which the Company ceases to control the entity. If necessary, the accounting policies of controlled entities' are aligned with the accounting policy applied by the Group. All intra-group balances, income, expenses and cash flows are eliminated on consolidation.

        Those entities where the Group exercises significant influence are recognized as associates and accounted for using the equity method. Significant influence is the power to participate in the financial and operating policy decisions of the investee but is not control or joint control over those policies. These entities are recognized at cost at the time of acquisition and adjusted thereafter to recognize the Group's share of the profit or loss and other comprehensive income. The carrying amount of the investment in such entities may include goodwill as the positive difference between the cost of the investment and Group's proportionate share in the fair values of the entity's identifiable assets and liabilities. The carrying amount of the investment accounted for using the equity method is tested for impairment provided there are indications of impairment. If the carrying amount of the investment exceeds its recoverable amount, an impairment loss is recognized in the amount of the difference. The recoverable amount is measured at the higher of fair value less costs of disposal and value in use. The Group presents its share in profits or losses in associates within operating profit if those interests are viewed as part of Group's core operations. As of December 31, 2017, only MTS Belarus was considered to be a part of Group's core operating activity. Shares in profits and losses of other Group's associates were presented as non-operating items.

        The Group has joint operations with MTS Bank, a Group's associate, relating to the development of the MTS Dengi project and Vimpelcom, relating to construction of LTE base stations. Joint operations are characterized by the fact that the operators that have joint control over the arrangement have a right to the assets, and obligations for the liabilities, relating to the arrangement. Respectively, each operator accounts for its share of the joint assets and its agreed share of any liabilities, and recognizes its share of the output, revenues and expenses incurred under the arrangement.

        Investments in shares of the companies over which the Group does not have control or an ability to exercise significant influence are accounted for under the cost method. The Group does not evaluate cost-method investments for impairment unless there is an indicator of impairment.

        Functional currency translation methodology—As of December 31, 2017, the functional currencies of Group entities were as follows:

•

For entities incorporated in the Russian Federation, Dega and MTS International—the Russian Ruble ("RUB");



•

For Vodafone Ukraine—the Ukrainian Hryvna;



•

For MTS Armenia—the Armenian Dram;



•

For MTS Turkmenistan—the Turkmenian Manat;



•

For MTS Belarus—the Belorussian Ruble;



•

For NVision Czech Republic—the Czech Crown.

        Foreign-currency transactions are translated into the functional currency at the exchange rates at the dates of the transactions. At the reporting date, monetary items denominated in foreign currencies are translated at the closing rate, whereas non-monetary items are stated at the exchange rate at the date of their recognition. Exchange rate differences are recognized in profit or loss.

        For entities whose records are maintained in their functional currency, which is other than the reporting currency, all year-end assets and liabilities have been translated into U.S. Dollars ("USD") at the period-end exchange rate set by local central banks. Subsequently, U.S. Dollars balances have been translated into Russian Rubles at the period-end exchange rate set by the Central Bank of Russia. Revenues and expenses have been translated at the average exchange rate for the period using cross-currency exchange rate via U.S. Dollar as described above. Translation differences resulting from the use of these rates are reported as a component of other comprehensive income.

        Management estimates—The preparation of the consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

        Significant estimates include allowance for doubtful accounts and inventory obsolescence, the valuation of assets acquired and liabilities assumed in business combinations, the recoverability of investments and the valuation of goodwill, property, plant and equipment and intangible assets, liability under put option agreement, certain provisions and financial instruments.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        Property, plant and equipment—Property, plant and equipment, including improvements, are stated at cost. Property, plant and equipment with a useful life of more than one year is capitalized at historical cost and depreciated on a straight-line basis over its expected useful life, as follows:

        The estimated useful lives and depreciation method are reviewed at the end of each reporting period, with the effect of any changes in estimate accounted for on a prospective basis.

        The gain or loss arising on the disposal of an item of property, plant and equipment is determined as the difference between any sale proceeds and the carrying amount of the asset and is recognised in the consolidated statement of profit or loss.

        Construction in progress and equipment held for installation is not depreciated until the constructed or installed asset is ready for its intended use. Maintenance and repair costs are expensed as incurred, while upgrades and improvements are capitalized.

        Borrowing costs—Borrowing costs directly attributable to the acquisition, construction or production of a qualifying asset during the construction phase that necessarily takes a substantial period of time are capitalized as part of property, plant and equipment until the asset is substantially ready for its intended use. The Group considers a construction period of more than six months to be substantial.

        Other intangible assets—Other intangible assets primarily consist of billing, telecommunication, accounting and office software as well as numbering capacity, customer base and licenses. These assets are assets with finite useful lives. They are initially recognized at cost and amortized on a straight-line basis over their estimated useful lives.

        Goodwill—Goodwill represents an excess of consideration transferred plus the fair value of any non-controlling interest ("NCI") in the acquiree at the acquisition date over the fair values of the identifiable net assets of the acquired entity. Goodwill is not amortized, but is tested for impairment based on the recoverable amount of the cash-generating unit ("CGU") to which the goodwill is allocated. The impairment test is carried out on a regular basis at the end of each financial year, as well as whenever there are indications that the carrying amount of the CGU unit is impaired. For the purpose of impairment testing, goodwill acquired in a business combination is allocated to each of the CGU units that are expected to benefit from the synergies of the combination.

of the CGU unit to which goodwill is allocated exceeds its recoverable amount, goodwill allocated to this CGU must be reduced. Impairment losses for goodwill must not be reversed. If the impairment loss recognized for the CGU exceeds the carrying amount of the allocated goodwill, the additional amount of the impairment loss is recognized through the pro-rata reduction of the carrying amounts of the assets allocated to the CGU.

        Impairments of intangible assets and property, plant and equipment—Impairments are identified by comparing the carrying amount with the recoverable amount. If no future cash flows generated independently of other assets can be allocated to individual assets, recoverability is assessed on the basis of the CGU to which the assets can be allocated. At each reporting date, the Group assesses whether there is any indication that an asset may be impaired. If any such indication exists, the recoverable amount of the asset or CGU must be determined. In addition, at the end of each period the Group assesses whether there is any indication that an impairment loss recognized in prior periods for an asset other than goodwill no longer exists or may be decreased. If the impairment loss is reversed, the carrying amount of the asset (or a CGU) is increased to the revised estimate of its recoverable amount, but so that the increased carrying amount does not exceed the carrying amount that would have been determined had no impairment loss been recognized for the asset (or CGU) in prior years.

        Assets and disposal groups held for sale—The Group classifies assets and disposal groups as held for sale if their carrying amount will be recovered principally through a sale transaction rather than through continuing use. This condition is met only when the assets (or disposal group) are available for immediate sale in its present condition subject only to terms that are usual and customary for sales of such assets (or disposal groups) and their sale is highly probable to occur within a year. Held for sale assets and disposal groups are measured at the lower of carrying amount or fair value less cost to sell.

        Inventories and spare parts—Inventories are stated at the lower of cost or net realizable value. Inventory cost is determined using the weighted average cost method. Handsets and accessories held for sale are expensed when sold. The Group regularly assesses its inventories for obsolete and slow-moving stock.

        Value-added tax ("VAT")—Value-added tax related to sales is payable to the tax authorities on an accrual basis based upon invoices issued to the customer. VAT incurred for purchases may be reclaimed from the state, subject to certain restrictions, against VAT related to sales.

        Income taxes—Income taxes of the Group's Russia-incorporated entities have been computed in accordance with Russian legislation and are based on the taxable profit for the period. The corporate income tax rate in Russia is 20%. The withholding tax rate on dividends paid within Russia is 13%. The foreign subsidiaries of the Group are paying withholding taxes in their respective jurisdictions. Deferred tax assets and liabilities are recognized for temporary differences between the carrying amounts of assets and liabilities in the consolidated financial statements and the corresponding tax bases of assets and liabilities that will result in future taxable or deductible amounts. The deferred tax assets and liabilities are measured using the enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        Financial instruments—A financial instrument is any contract that gives rise to a financial asset of one entity and a financial liability or equity instrument of another entity. Financial assets include, in particular, cash and cash equivalents, trade and other receivables, investments (mainly deposits with original maturity of more than three months, originated loans and notes, as well as debt securities) and derivative financial assets. Financial liabilities generally substantiate claims for repayment in cash or another financial asset. In particular, this includes bonds, trade and other payables, bank loans, finance lease obligations and derivative financial liabilities. Financial instruments are recognized as soon as the Group becomes a party to the contractual regulations of the financial instrument.

        Financial assets and financial liabilities are recognized initially at fair value plus transaction costs that are directly attributable to the acquisition or issue of the financial asset or financial liability, except for a financial asset or liability accounted for at fair value through profit or loss, in which case transaction costs are expensed. Subsequently they are measured either at amortized cost or fair value depending on classification of those assets and liabilities based on their purpose. Financial assets can be classified as 1) financial assets at fair value through profit or loss; 2) held-to-maturity investments; 3) available for sale financial assets; 4) loans and receivables. Financial liabilities can be classified as 1) financial liabilities at fair value or 2) other financial liabilities.

        Cash and cash equivalents—Cash and cash equivalents represent cash on hand and in bank accounts, as well as short-term bank deposits, which have original maturities of less than three months. Such investments are measured at amortized cost.

        Trade and other receivables—Trade and other receivables are stated at their nominal value as reduced by appropriate allowance for doubtful accounts.

        Allowance for doubtful accounts—The Group provides an allowance for doubtful accounts based on management's periodic review with respect to the recoverability of trade receivables, advances given, loans and other receivables. Such allowance reflects specific cases, collection trends or estimates based on evidence of collectability.

        Short-term investments—Short-term investments mainly represent investments in loans, time deposits, which have original maturities in excess of three months and are repayable in less than twelve months, as well as investment in debt securities. Investment in debt securities are classified as financial assets at fair value through profit or loss, if they held for trading, otherwise they are classified as available for sale with unrealized gains and losses recorded as part of other comprehensive income. Deposits and loans are carried at amortized cost.

        Other investments—Other investments consist primarily of long-term deposits, which are repayable in more than a year, loans, notes and equity holdings in private companies. Deposits, loans and notes not quoted in active market are classified as loans and receivables and carried at amortized cost. The notes quoted in active market are classified based on Group's intention and ability to hold these notes to maturity either as held to maturity or available for sale. The Group reviews these investments for indicators of impairment on a regular basis.

        Trade payables and other non-derivative financial liabilities are measured at amortized cost.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        Hedging activities—The Group uses derivative instruments, including interest rate and foreign currency swaps, to manage foreign currency and interest rate risk exposures. The Group measures derivatives at fair value and recognizes them as either other current or other non-current financials assets or liabilities in the consolidated statement of financial position. Cash flows from derivatives are classified according to their nature. The Group reviews related fair value hierarchy classifications on a quarterly basis. The fair value measurement of the Group's derivative instruments is based on the observable yield curves for similar instruments.

        The Group designates derivatives as either fair value hedges or cash flow hedges in case the required criteria are met.

        Fair value hedges—Changes in the fair value of derivatives that are designated and qualified as fair value hedges are recognized in profit or loss immediately together with any changes in the fair value of the hedged asset or liability that are attributed to the hedged risk.

        Cash flow hedges—The effective portion of changes in the fair value of derivatives that are designated and qualified as cash flow hedges are recognized in other comprehensive income.

        The gain or loss relating to the ineffective portion is recognized immediately in profit or loss. Gains or losses accumulated in other comprehensive income are immediately reclassified into consolidated statement of profit or loss when related hedged transactions affects earnings.

        For derivatives that do not meet the conditions for hedge accounting, gains and losses from changes in the fair value are recorded immediately in profit or loss.

        Assets and liabilities related to multiple derivative contracts with one counterparty are not offset by the Group.

        Fair value of financial instruments—Fair value of financial assets and liabilities is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. The three-tier hierarchy for inputs used in measuring fair value, which prioritizes the inputs used in the methodologies of measuring fair value for assets and liabilities, is as follows:

•

Level 1—Quoted prices in active markets for identical assets or liabilities;



•

Level 2—Observable inputs other than quoted prices in active markets for identical assets and liabilities;



•

Level 3—No observable pricing inputs in the market.

        Financial assets and financial liabilities are classified in the three-tier hierarchy based on the lowest level of input that is significant to the fair value measurements. The Group's assessment of the significance of a particular input to the fair value measurements requires judgment, and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

        Liability under put option agreement—To optimize the structure of business acquisitions and to defer payment of the purchase price, the Group enters into put and call option agreements to acquire the remaining non-controlling stakes in newly acquired subsidiaries. Upon initial recognition, the commitment to purchase non-controlling interests is recognized as a financial liability for the present value of the redemption amount, which approximates its fair value. Subsequent changes in the value of the commitment are recognized in profit or loss for the reporting period.

        Finance leases—Leases are classified as finance whenever the terms of the lease transfer substantially all risks and rewards incidental to ownership of the leased asset to the Group. At the commencement of the lease term, the leased asset is measured at the lower of fair value or present value of the future minimum lease payments and is depreciated over the lease term. The corresponding liability is recognized in the consolidated statement of financial position within borrowings. The discount rate used in the calculating the present value of minimum lease payments is the interest rate implicit in the lease. If there is no interest rate in the lease, the Group's incremental borrowing rate is used.

        Share-based payment programs—Equity-settled share-based payment transactions are measured at fair value on the grant date. The fair value of the obligation is recognized as personnel costs over the vesting period and offset against capital reserves. For cash-settled share-based payment transactions, the fair value of the obligation is newly determined at each reporting date and at the settlement date, and the changes in the fair value are recognized in profit or loss, until the liability is settled.

        Retirement benefits—MGTS, a subsidiary of the Group, has historically offered its employees certain benefits upon and after retirement, which form a defined benefit plan. The cost of providing benefits is determined using projected unit credit method with actuarial valuation being carried out at the end of each reporting period.

        Provisions—Provisions are recognized when the Group has a present obligation (legal or constructive) as a result of past event, it is probable that the Group will be required to settle that obligation and a reliable estimate can be made of the amount of the obligation. Provisions are measured at managements' best estimate of the expenditure required to settle the obligation at the reporting date and are discounted to present value where the effect is material. The main provisions the Group holds are in relation to employees' bonuses and other rewards, decommissioning and restoration obligation, tax provisions as well as legal claims.

        Provision for decommissioning and restoration—The Group calculates a provision for decommissioning and restoration when the Group has a legal or constructive obligation in connection with the retirement of tangible long-lived assets. The Group's obligations relate primarily to the cost of removing its equipment from sites. The Group records the present value of provision for decommissioning and restoration as non-current provisions in the consolidated statement of financial position.

        Subscriber prepayments—The Group requires the majority of its customers to pay in advance for telecommunications services. All amounts received in advance of services provided are recorded as a

subscriber prepayment liability and are not recognized as revenues until the related services have been provided to the subscriber.

        Treasury stock—Shares of common stock repurchased by the Group are recorded at cost as treasury stock and reduce the shareholders' equity in the Group's consolidated financial statements.

        Revenue recognition—Revenue includes all revenues from the ordinary business activities of the Group. Revenues are measured at the fair value of the consideration received or receivable and recorded net of value-added tax. The Group recognizes revenue when the amount of revenue and related costs can be measured reliably; when it is probable that future economic benefit will flow to the Group; and when specific criteria have been met, as described below.

        Revenues derived from wireless, local telephone, long distance, data and video services are recognized when services are provided. This is based upon either usage (minutes of traffic processed, volume of data transmitted) or period of time (monthly subscription fees).

        Content revenue is presented net of related costs when the Group acts as an agent of the content providers while gross revenue and related costs are recorded when the Group acts as a primary obligor in the arrangement.

        Upfront fees received for connection of new subscribers, installation and activation of wireless, wireline and data transmission services ("connection fees") are deferred and recognized over the estimated average subscriber life, as follows:

        The Group calculates an average life of mobile subscribers for each region in which it operates and amortizes connection fees based on the average life specific to that region.

        Customer incentives—Incentives provided to customers are usually offered on signing a new contract or as part of a promotional offering. Incentives, representing the reduction of the selling price of the service (free minutes and discounts) are recorded in the period to which they relate, when the respective revenue is recognized, as a reduction to both trade receivables and service revenue.

        The Group regularly provides special incentives to its retail customers. Generally the Group sells mobile devices of worldwide known brands with an offer of free telecommunication services for a time period from one to twelve months. Such arrangements with a customer provide for two deliverables—a mobile device delivered immediately and mobile services to be consumed in the future. The consideration received from a customer is allocated between the deliverables based on their standalone value on the market. Revenue on the devices sales is recognized at the moment of their sale, and the revenue on provision of free telecommunication services is deferred and recognized upon consumption by a subscriber.

        Roaming discounts—The Group enters into roaming discount agreements with a number of wireless operators. According to the terms of the agreements the Group is obliged to provide and entitled to

receive a discount that is generally dependent on the volume of inter operator roaming traffic. The Group uses various estimates and assumptions, based on historical data and adjusted for known changes, to determine the amount of discount to be received or granted. Such estimates are adjusted monthly to reflect newly-available information.

        The Group accounts for discounts received as a reduction of roaming expenses and rebates granted as reduction of roaming revenue. The Group considers terms of the various roaming discount agreements in order to determine the appropriate presentation of the amounts receivable from and payable to its roaming partners in its consolidated statement of financial position.

        Sales and marketing expenses—Sales and marketing expenses consist primarily of dealers' commissions and advertising costs. Dealers' commissions are linked to revenues received during the six-month period from the date a new subscriber is activated by a dealer. The Group expenses these costs as incurred.

        Netting—The Group offsets its financial assets and financial liabilities only if it has a legally enforceable right to set off the recognized amounts and intends either to settle on a net basis or to realise the asset and settle the liability simultaneously.

Standards, interpretations and amendments adopted on January 1, 2017

        The Group has applied amendments to IAS 7 Disclosure Initiative for the first time in the current year. The amendments require an entity to provide disclosures that enable users of financial statements to evaluate changes in liabilities arising from financial activities, including both cash and non-cash changes.

        The Group's liabilities consist of borrowings (Note 15) and certain other financial liabilities (Note 18). A reconciliation between the opening and closing balances of these items is provided in Note 16. Consistent with the transition provisions of the amendments, the Group has not disclosed comparative information for the prior period.

        None of the standards, interpretations and amendments adopted by the Group on January 1, 2017 had a significant effect on the Group's consolidated financial statements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND NEW ACCOUNTING PRONOUNCEMENTS (Continued)

Standards, interpretations and amendments in issue but not yet effective

        The Group has not applied the following new and revised IFRSs that have been issued but not yet effective:

        IFRS 9, Financial Instruments.    IFRS 9 regulates the classification and measurement of financial assets and liabilities and requires certain additional disclosures. The primary changes relate to the assessment of hedging arrangements and provisioning for potential future credit losses on financial assets as well as recognition of modification gain or loss for all revisions of estimated payments or receipts, including changes in cash flows arising from a modification or exchange of a financial liability, that does not result in its derecognition.

        Based on Group's current estimate there will be no material effect from earlier recognition of future credit losses on financial assets or for current hedge accounting. The estimated gain in relation of the Group's modified liabilibies will amount to RUB 3 bln.

        The Group will recognize the cumulative effect arising from the transition as an adjustment to the opening balance of equity. Prior period's comparative will not be restated.

        IFRS 15, Revenue from Contracts with Customers.    This standard provides a single, principles-based five-step model for the determination and recognition of revenue to be applied to all contracts with customers. It replaces the existing standards IAS 18, Revenue, and IAS 11, Construction Contracts. The core principle of IFRS 15 is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the standard, an entity recognizes revenue when (or as) a performance obligation is satisfied, i. e. when "control" of the goods or services

underlying the particular performance obligation is transferred to the customer. Far more prescriptive guidance has been added in IFRS 15 to deal with specific scenarios than exists in the current guidance. Furthermore, extensive disclosures are required by IFRS 15.

        The Group currently anticipates that the main effect from the adoption of IFRS 15 on the Group's consolidated financial statements will relate to the deferral of certain incremental costs incurred in acquiring or fullfilling a contract with a customer. Such contract costs will be amortised over the period of benefit. The Group will use a practical expedient from IFRS 15 allowing to expense contract costs as incurred when the amortization period is one year or less. The Group estimates the additional asset stemming from the capitalization of contract costs to amount to RUB 5.9 bln.

        Other anticipated impacts of the standard includes later recognition of revenue in cases, where "material rights" (such as offering additional products and services free of charge) are granted to the customers, and the reallocation of renumeration between components of contracts with customers. The Group estimates the additional deferred revenue to be recognized as a result of applying IFRS 15 will not be material.

        The Group will utilize the option for simplified initial application, so that contracts that are not completed by January 1, 2018 will be accounted for as if they had been recognized in accordance with IFRS 15 from the very beginning. The cumulative effect arising from the transition will be recognized as an adjustment to the opening balance of equity in the year of initial application. The prior period comparatives will not be restated.

        IFRS 16, Leases.    This standard principally requires lessees to recognize assets and liabilities for all leases and to present the rights and obligations associated with these leases in the statement of financial position. The standard also includes new provisions on the definition of a lease and its presentation, on disclosures in the notes, and on sale and leaseback transactions.

        The Group elected to early adopt the standard effective January 1, 2018 concurrent with the adoption of the new standard related to revenue recognition.

        The Group will make use of the following practical expedients:

•

relief from the requirement to reassess whether a contract is, or contains the lease;



•

use of assessment of whether leases are onerous applying IAS 37, Provisions, Contingent Liabilities and Contingent Assets, immediately before the date of initial application as an alternative to performing an impairment review;



•

permission to exclude initial direct costs from the measurement of the right-of-use asset at the date of initial application;



•

use hindsight, such as in determining the lease term if the contract contains options to extend or terminate the lease.

        Based on analysis performed, the Group expects its lease liability and non-current assets to increase by no less than RUB 134 bln, respectively, as a result of applying IFRS 16. In terms of future effects on the statement of profit or loss, the lease expenses will be for depreciation of right-of-use

assets and interest of lease liability; interest will typically be higher at the earlier stages of a lease and reduce over the term.

        The Group will recognize the cumulative effect arising from the transition as an adjustment to the opening balance of equity. Prior period's comparative will not be restated.

        The above assessment for IFRS 9, 15 and 16 is preliminary because not all transition work has been finalized. The actual impact of adopting the new standards on 1 January 2018 may change because their adoption will require the Group to revise its accounting processes and internal controls and these changes are not yet complete, while the new accounting policies, assumptions, judgements and estimation techniques employed are subject to changes until the Group finalizes its first consolidated financial statements that include the date of initial application.

        Other mentioned IFRS pronouncements do not have a material impact on the Group's consolidated financial statements.

3. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS

1. Critical accounting estimates

        A critical accounting estimate is an estimate that is both important to the presentation of the Group's financial position and requires management's most difficult, subjective or complex judgments, often as a result of the need to determine estimates and develop assumptions about the outcome of matters that are inherently uncertain.

        Management evaluates such estimates on an on-going basis, based upon historical results, historical experience, trends, consultations with experts, forecasts of the future, and other methods which management considers reasonable under the circumstances. Management considers the accounting estimates discussed below to be its critical accounting estimates, and, accordingly, provides an explanation of each.

2. Depreciation and amortization of non-current assets

        Depreciation and amortization expenses are based on management estimates of useful life, residual value and amortization method of property and equipment and intangible assets. Estimates may change due to technological developments, competition, changes in market conditions and other factors and may result in changes in the estimated useful life and in the amortization or depreciation charges. Technological developments are difficult to predict and management views on the trends and pace of development may change over time. Some of the assets and technologies, in which the Group invested several years ago, are still in use and provide the basis for the new technologies. Critical estimates in the evaluations of useful lives for intangible assets include, but are not limited to, the estimated average customer relationship based on churn, the remaining license period and the expected developments in technology and markets.

        The useful lives of property and equipment and intangible assets are reviewed at least annually, taking into consideration the factors mentioned above and all other important relevant factors. The

3. SIGNIFICANT ACCOUNTING JUDGMENTS, ESTIMATES AND ASSUMPTIONS (Continued)

actual economic lives of intangible assets may be different from useful lives estimated by management, thereby resulting in a different carrying value of intangible assets with finite lives.

        The Group continues to evaluate the amortization period for intangible assets with finite lives to determine whether events or circumstances warrant revised amortization periods. A change in estimated useful lives is a change in accounting estimate, and depreciation and amortization charges are adjusted prospectively. See Notes 11 and 14 for further information.

3. Impairment of non-current assets

        The Group has made significant investments in property, plant and equipment, intangible assets, goodwill and other investments.

        Pursuant to IAS 36, goodwill and other intangible assets with indefinite useful lives and intangible assets not yet brought into use must be tested for impairment annually or more often if indicators of impairment exist. Other assets are tested for impairment when circumstances indicate that there may be a potential impairment.

        Estimating recoverable amounts of assets and CGUs must, in part, be based on management's evaluations, including the determination of the appropriate CGUs, the discount rate, estimates of future performance, the revenue generating capacity of the assets, timing and amount of future purchases of property and equipment, assumptions of the future market conditions and the long-term growth rate into perpetuity (terminal value). Changing the assumptions selected by management, in particular, the discount rate and growth rate assumptions used to estimate the recoverable amounts of assets, could significantly impact the Group's impairment evaluation and hence results.

        All of the Group's operations are in countries with emerging markets. The political and economic situation in these countries may change rapidly and potentially have a significant impact on these countries. Changing state of the world economy, and increased macroeconomic risks, impact management's assessment of cash flow forecasts and the discount rates applied.

        There are significant variations between different markets with respect to growth, mobile penetration, Average Revenue Per User ("ARPU"), market share and similar parameters, resulting in differences in operating margins. The future developments of operating margins are important in the Group's impairment assessments, and the long-term estimates of these margins are highly uncertain.

        See Notes 12 and 13 for further information about goodwill and impairment test.

4. Fair value of financial instruments

        Where the fair value of financial assets and financial liabilities recorded in the statement of financial position cannot be derived from active markets, their fair value is determined using valuation techniques, including discounted cash flow models. The inputs to these models are taken from observable markets where possible, but when this is not feasible, a degree of judgment is required in establishing fair values. The judgments include considerations of inputs such as liquidity risk, credit risk and volatility. Changes in assumptions about these factors could affect the reported fair value of financial instruments. See Note 18 for further information.

5. Provisions and contingencies

        The Group is subject to various legal proceedings, disputes and claims, including regulatory discussions related to the Group's business, licenses, tax positions and investments, where the outcomes are subject to significant uncertainty. In addition, significant uncertainty exists in relation of employee bonuses and other rewards, which depend on their individual performance and Group's results. Management evaluates, among other factors, the degree of probability of an unfavorable outcome and the ability to make a reasonable estimate of the amount of loss or related expense. Unanticipated events or changes in these factors may require the Group to increase or decrease the amount recorded or to be recorded for a matter that has not been previously recorded because it was not considered probable.

        See Note 17 and Note 30 for further information.

4. BUSINESS ACQUISITIONS AND DISPOSALS

1. Acquisitions after the reporting period

        Acquisition of Kulturnaya Sluzhba—In January 2018, the Group acquired a 78.2% ownership interest in Kulturnaya Sluzhba LLC ("KS"), operating under the trademark Ponominalu.ru. The purchase price comprised of cash payment, contingent consideration, payable in 12 months after the acquisition date and earn-out payments, the amounts to be paid to the sellers in 2018 if agreed upon financial targets are met by KS.

        Acquisition of Moskovskaia Direktciia Teatralno-Kontcertnyh i Sportivno-Zrelishchnyh Kass —In February 2018, the Group acquired a 100% ownership interest in Moskovskaia Direktciia Teatralno-Kontcertnyh i Sportivno-Zrelishchnyh Kass LLC ("MDTZK"), operating under the trademark Ticketland.ru. The purchase price comprised of cash payment and contingent consideration, payable in 12 months after the acquisition date.

        These acquisitions allow the Group to enter the event ticket market, while broadening the Group's suite of digital services, and integrate a key new product into existing loyalty program and mobile applications ecosystem.

4. BUSINESS ACQUISITIONS AND DISPOSALS (Continued)

        The following table summarizes the preliminary purchase price allocation for MDZTK and KS:

        The goodwill is mainly attributable to the expected synergies resulted from the acquisitions.

        The Group also entered into an option agreement with the shareholders of the KS, pursuant to which the Group has the right and obligation (in the form of a call and put option), with the put option exercisable at the request of non-controlling shareholders, to acquire their shares at a price calculated based on the future operating and financial results of KS.

        The Group has elected to measure the non-controlling interests in the acquiree at fair value.

        The fair value of the non-controlling interest has been estimated based on agreed formula in accordance with the agreement. The fair value measurements are based on significant inputs that are not observable in the market. The fair value estimate is based on:

•

An assumed discount rate of 10.2%



•

Average revenue of RUB 199 million



•

A net debt of RUB 83 million

        The receivables acquired (which principally comprised trade receivables) in these transactions with a fair value of RUB 274 million had gross contractual amounts of RUB 290 million. The best estimate at acquisition date of the contractual cash flows not expected to be collected is RUB 16 million.

2. Acquisitions in 2017

        Acquisition of Bashkortostan Cellular Communication—In July 2017, the Group acquired a 100% ownership interest in Bashkortostan Cellular Communication OJSC ("BCC"). BCC operates in the Republic of Bashkortostan and holding rights to use 450 MHz and 2,100 MHz radio frequencies. The acquisition enhances the Group's spectrum resources in the Republic of Bashkortostan. The purchase

price comprised of cash payment and contingent consideration, payable in 12 months after the acquisition date. The business combination was accounted for by applying the acquisition method.

        The following table summarizes the purchase price allocation for BCC at the date of acquisition:

        The excess of the consideration over the value of net assets acquired in the amount of RUB 62 million was allocated to goodwill which is attributable to the "Russia convergent" segment.

        Goodwill is mainly attributable to the expected synergies.

        Licenses acquired are amortized over a period of their remaining useful life of 15 years in average.

        Acquisition of Oblachny Retail—In October 2017, the Group acquired 50.82% of ownership interest in the Russian retail software developer Oblachny Retail LLC ("Oblachny Retail"), operating under trademark LiteBox, with a call and put option arrangement existing over another 49.18% of shares. The deal allows the Group to enter the cloud-based cash register market as a fully licensed fiscal data operator ("FDO") and a provider of integrated digital cash management solutions for B2B clients. The purchase price comprised of cash payment and contingent consideration, payable in 12 months after the acquisition date. As a part of business combination the Group also made a contribution of RUB 420 million to the share capital of an acquiree to provide funds for future development. The Group has elected to measure the non-controlling interests in the acquiree at fair value. The business combination was accounted for by applying the acquisition method.

        Tangible and intangible assets excluding goodwill—At the end of each reporting period, management of the Group reviews the carrying amounts of its tangible and intangible assets to determine whether there is any indication that those assets have suffered an impairment loss. If any such indication exists,

13. IMPAIRMENT REVIEW (Continued)

the recoverable amount of the assets is estimated in order to determine the extent of the impairment loss.

        When reviewing for indicators of impairment management of the Group considers the relationship between its market capitalization and book value, changes in country risk premiums and other.

        When the carrying amount of the CGU exceeds its recoverable amount, assets allocated to this CGU must be impaired.

        The recoverable amounts of the CGUs are determined based on their value in use. In assessing value in use, the estimated future cash flows are discounted to present value using a pre-tax discount rate that reflects current market assessments of the time value of money and the risks specific to the CGU.

        Future cash flows calculations are based on a five-year operations plan, which is prepared and approved by the management of the Group. Estimation of future cash flows requires assumptions to be made in respect of uncertain factors, including management's expectations of the following: OIBDA margin, timing and amount of future capital expenditure, terminal growth rates and appropriate discount rates to reflect the risks involved.

        During the year ended December 31, 2017 the Group recognized impairment charges in the amount of RUB 3,775 million, including RUB 3,204 million in respect of the non-current assets of the CGU "Turkmenistan" and RUB 571 million in respect of the non-current assets of the CGU "NVision Czech Republic". Impairment charges were recorded in a separate line item as a part of operating profit in the consolidated statements of profit or loss.

        CGU "Turkmenistan" provided mobile services across multiple regions of Turkmenistan.The impairment in the CGU "Turkmenistan" reflects uncertainty in respect of the ability to continue operations in Turkmenistan. In September, 2017, the Group's subsidiary in Turkmenistan suspended the provision of telecommucation services to its subscribers, due to the termination by Turkmen state-owned companies and state authorities of line rental, frequency allocation, interconnect, and other agreements necessary to servicing clients. The recoverable amount of the CGU "Turkmenistan" was equal to nil as of December 31, 2017.

        CGU "NVision Czech Republic" tailors in-house software solutions, provides support and managed services to telecom operators, delivers electronic and mechanical manufacturing services. The impairment in the CGU "NVision Czech Republic" reflects lower operating performance. The recoverable amount of the CGU "NVision Czech Republic" was RUB 954 million as of December 31, 2017.

        Impairment charges are attributable to operating segments of the Group, reported as a part of the "Other" category, which does not constitute a reportable segment (Note 26).

13. IMPAIRMENT REVIEW (Continued)

        The total amount of the impairment loss for the year ended December 31, 2017 was allocated to the carrying amounts of property, plant and equipment and other intangible assets as follows:

        During the year ended December 31, 2016 no impairment charges were recorded.

        As a result of impairment test as of December 31, 2015 the impairment charge of RUB 3.5 billion was recorded in a separate line item within operating profit in the consolidated statement of profit or loss in respect of the Group's investment in the CGU "Armenia". CGU "Armenia" provides mobile and fixed line services across multiple regions of Armenia. The impairment charge is attributable to the operating segment of the Group, reported as a part of the "Other" category, which does not constitute a reportable segment (Note 26). This charge relates solely to goodwill. The impairment reflects the decrease of interconnect traffic and related revenue due to dramatic growth of prices for international calling from Russia to Armenia. The recoverable amount of CGU "Armenia" was RUB 18.5 billion as of December 31, 2015.

Key assumptions used for value in use calculation:

        OIBDA margin and capital expenditures were primarily derived from internal sources, based on past experience and extended to include management expectations.

        The table below presents OIBDA margin utilized for value in use calculation of related CGUs:

        The table below presents capital expenditure as a percentage of revenue utilized for value in use calculation of related CGUs:

13. IMPAIRMENT REVIEW (Continued)

        The terminal growth rate into perpetuity has been determined based on the nominal gross domestic product rates for the country of operation, adjusted for specific characteristic of the CGUs business.

        The table below presents terminal growth rate utilized for value in use calculation of related CGUs:

        The discount rate, applied to measure free cash flow is the weighted average cost of capital according to the finance structure established for each CGU.

        The table below presents pre-tax rates for discounting of cash flows in functional currencies of related CGUs:

Sensitivity analysis

        Management believes that no reasonably possible change in any of the above key assumptions would cause the carrying value of any cash-generating unit to materially exceed its recoverable amount, except for the CGU "NVision Czech Republic".

        After the recognition of the impairment of non-current assets the carrying value of the CGU "NVision Czech Republic" is equal to the estimated recoverable amount, any adverse change in key assumptions would, in isolation, cause a further impairment loss to be recognized.

        The changes in the following table to assumptions used in the impairment review of the CGU "NVision Czech Republic" would have, in isolation, led to following changes to the impairment loss recognized in the year ended December 31, 2017:

18. FAIR VALUE OF FINANCIAL ASSETS AND LIABILITIES (Continued)

        The fair value measurement of the Group's derivative instruments and investments in Sistema-Capital trust management is based on the observable yield curves for similar instruments and represents the estimated amount the Group would receive or pay to terminate these agreements at the reporting date, taking into account current interest rates, foreign exchange spot and forward rates.

        The table below presents the fair value of financial instruments:

        For the year ended December 31, 2017, 2016 and 2015, net realized gains and losses of Level 3 liabilities resulting from fair value measurements amounted to RUB 120 million gain, RUB 199 million gain and RUB 1,014 million gain, respectively and were recognized as a part of change in fair value of financial instruments' in consolidated statement of profit or loss. No unrealized gains or losses of Level 3 liabilities resulted from fair value measurements were recognized during the years ended December 31, 2017, 2016 and 2015.

        The liability under put option agreement for redeemable NCI in MTS Armenia in amount of RUB 2,012 million is measured at fair value using a discounted cash flow technique. The most significant quantitative inputs used to measure the fair value of the liability under put option agreement for redeemable NCI in MTS Armenia are presented in the table below:

        The liability under option agreement for redeemable NCI in Oblachny Retail in amount of RUB 412 million is calculated based on agreed fixed formula, which includes future operating and financial

indicators. The most significant quantitative inputs used to measure the fair value of the liability under option agreement for redeemable NCI in Oblachny Retail are presented in the table below:

        The carrying value of the Group's financial instruments accounted for at amortized cost approximates their fair value due to their short-term nature and market interest rates, except for borrowings, gross of debt issuance cost, as disclosed in the table below:

        The fair value of the Group's bank and other loans is measured using a discounted cash flow technique. The discount rate used in the discounted cash flow analysis is determined on the base of the market rate for bank loans available to the Group.

        While management has used available market information in estimating the fair value of its financial instruments, the market information may not be fully reflective of the value that could be realized in the current circumstances.

        There were no transfers between levels of inputs within the hierarchy during the years ended December 31, 2017, 2016 and 2015.

        There were no transfers between the accounting categories of financial instruments during the years ended December 31, 2017, 2016 and 2015.

19. FINANCIAL RISK MANAGEMENT

        As part of its business the Group is exposed to several types of financial risks: market risks, credit (or counterparty) risks, and liquidity risks. Risks mitigating activities are mainly performed at the Group headquarters by the corporate finance personnel and are subject to the approval of the Group's supervisory bodies—Board of Directors and Budget committee.

Market risk

        Market risk is the risk that the fair value of future cash flows of a financial instrument will fluctuate because of changes in market prices. The Group is primarily exposed to the following types of market risks: interest rate risk and currency exchange rates fluctuations. Financial instruments affected

by market risk include loans and borrowings, deposits, and derivative financial instruments. The sensitivity analyses in the following sections relate to the financial position as of December 31, 2017, 2016 and 2015.

Interest rate risks

        Interest rate risk is the risk that the fair value or future cash flows of a financial instrument will fluctuate because of changes in market interest rates. The Group manages its interest rate risk by having a balanced portfolio of fixed and variable rate loans and borrowings.

•

Variable interest rate

        Group's bank loans denominated in US Dollars and Euros primarily bear floating interest rate. To eliminate the exposure of changes in variable interest rates related to its debt obligations, the Group enters into variable-to-fixed interest rate swap agreements, so that interest rate swap matches the exact maturity dates of the underlying debt allowing for highly-effective cash flow hedges. In aggregate, the Group entered into variable-to-fixed interest rate swap agreements designated to manage the exposure of changes in variable interest rates related to 100% and 28.6% of the Group's bank loans with variable rates outstanding as of December 31, 2017 and 2016, respectively.

•

Fixed interest rate risk

        Group's Notes and bank loans denominated in Russian Rubles bear primarily fixed interest rates. To eliminate the exposure of changes in value of debt obligations, the Group enters into fixed-to-variable interest rate swap agreements. In aggregate, the Group entered into fixed-to-variable interest rate swap agreements designated to manage the exposure of changes in value of the debt related to 7.9% and 12.9% of the Group's Notes and bank loans with fixed rates outstanding as of December 31, 2017 and 2016, respectively.

        The notionals related to interest rate derivative instruments amounted to RUB 49,429 million and RUB 49,451 million as of December 31, 2017 and 2016, respectively.

Sensitivity analysis

        A reasonably possible increase of 100 basis points in short term interest rates would have resulted in RUB 44 million, RUB 704 million and RUB 933 million future increases of interest expense for the years ended December 31, 2017, 2016 and 2015, respectively. The same decrease in short term interest rates would have resulted in RUB 44 million, RUB 704 million and RUB 933 million future decreases of finance cost for the years ended December 31, 2017, 2016 and 2015, respectively. There will be no material impact on equity.

        The interest rate sensitivity analysis was performed based on a constant position of fixed and floating rate debt.

Foreign currency risks

        Foreign currency risk is the risk that the fair value or future cash flows will fluctuate because of changes in foreign exchange rates. The Group's exposure to the risk of changes in foreign exchange

rates relates primarily to the Group's financing activities. The Group manages its currency risk by hedging significant foreign currency cash outflows with derivatives and by using money market instruments.

        The Group has entered into several cross-currency swap agreements. The contracts designated to manage the exposure of changes in currency exchange rate. The contracts assumed periodic exchange of principal and interest payments from RUB-denominated amounts to USD-denominated amounts at a specified rate. The rate was determined by the market spot rate upon issuance. Cross-currency interest rate swap contracts mature in 2019-2024.

        In aggregate the Group entered into cross-currency interest rate swap agreements designated to manage the exposure of changes in currency exchange rate for 39.6% of the Group's USD-denominated Notes and bank loans outstanding as of December 31, 2017 and 29.2% of its USD-and Euro-denominated Notes and bank loans outstanding as of December 31, 2016.

        The notionals related to currency derivative instruments amounted to RUB 28,669 million and RUB 25,885 million as of December 31, 2017 and 2016, respectively.

        The Group has entered into deliverable currency forward agreements to minimize foreign currency risk exposure for operating activities. The contracts assumed the purchase or sale of the agreed amount of currency at a specified exchange rate and date. The rate was determined by the market spot rate upon issuance. As the result of deliverable currency forward agreements, unfulfilled as of December 31, 2017, 2016 and 2015, the Group recognized nil, RUB 142 mln loss and nil in the consolidated statement of profit and loss for the years ended December 31, 2017, 2016 and 2015.

        The notionals related to deliverable currency forward instruments, unfulfilled as of December 31, 2017 and 2016, amounted to nil and RUB 18,339 mln, respectively.

        The following table presents the effect of the Group's swap agreements designated as cash flow hedges in accumulated other comprehensive income for the years ended December 31, 2017, 2016 and 2015.

19. FINANCIAL RISK MANAGEMENT (Continued)

        The following tables demonstrate the sensitivity to a reasonably possible change in USD and EUR exchange rates, with all other variables held constant.

        The movement in the pre-tax effect is a result of a change in monetary assets and liabilities denominated in US dollars and Euro, where the functional currency of the entity is a currency other than US dollars and Euro.

        There will be no material impact on equity.

        The Group's exposure to foreign currency changes for all other currencies is not material.

Liquidity risk

        Liquidity risk is the risk of a shortage of funds. The Group's policy is to borrow centrally using a mixture of long-term and short-term borrowing facilities. These borrowings, together with cash generated from operations are utilized to meet anticipated funding requirements. The Group assessed the concentration of risk with respect to refinancing its debt and concluded it to be low.

        The Group manages liquidity risk on long-term borrowings by maintaining a varied maturity profile and a required net debt position, therefore minimizing refinancing risk. Long-term borrowings mature between one and 8 years.

        As at December 31, 2017, current liabilities exceeded current assets by RUB 10,639 million. Management believes the Group has sufficient existing and continuing access to liquidity through both operating cash flows and the availability of committed credit facilities of RUB 36,000 million (Note 15).

Credit risk

        Credit risk is the risk that a counterparty will not meet its obligations under a financial instrument, leading to a financial loss. The Group is exposed to credit risk primarily from its investing activities.

19. FINANCIAL RISK MANAGEMENT (Continued)

        The Group considers its exposure to credit risk as of December 31, 2017, and 2016 to be as follows:

        In accordance with the Group's financial instruments management policy, the aggregate credit risk the Group may have with one counterparty is limited. The Group maintains a mixture of cash and cash equivalents, investments, derivatives and certain other financial instruments with financial institutions. These financial institutions are located in different geographical regions and the Group's policy is designed to limit exposure to any one institutions. As part of its risk management processes, the Group performs periodic evaluations of the relative credit standing of the financial institutions.

        On December 15, 2015 Barclays bank and the Group signed an addendum to existing cross currency swap agreements. According to the terms of the addendum parties agreed to set credit exposure limits to one another, which permits to mitigate their credit risk by requiring other party to transfer collateral payments. The balance of Barclays bank's transfer of collateral payments to the Group is RUB 1.0 billion and RUB 2.9 billion as of December 31, 2017 and 2016, respectively.

        Concentrations of credit risk with respect to trade receivables are limited given that the Group's customer base is large and unrelated. Therefore management believes there is no further credit risk provision required in excess of the normal provision for bad and doubtful receivables.

20. INCOME TAX

        Significant components of income tax expense for the year ended December 31, 2017, 2016 and 2015 was as follows:

        Income tax expense on continuing operations excludes the tax income from the discontinued operations of RUB nil, RUB 192 million and RUB 661 million for the year ended December 31, 2017, 2016 and 2015, respectively; it has been included in loss from discontinued operations (Note 27).

        Movements in the deferred tax assets and liabilities for the year ended December 31, 2017 were as follows:

        The Group recognizes deferred income tax on future dividend distributions from foreign subsidiaries and associates which are based on cumulative undistributed earnings of those foreign subsidiaries in accordance with local statutory accounting regulations.

        The Group recognizes deferred tax assets in respect of tax losses carried forward to the extent that realization of tax losses against future taxable profit is probable. Deferred tax assets related to tax losses of the Group's subsidiaries are recognized based on the fact that certain tax planning opportunities are available to these subsidiaries that will create taxable profit in the period in which the unused tax losses can be utilized. The amount of the deferred tax asset considered realizable, however, could be remeasured if estimates of future taxable income are changed.

        Federal law #401-FZ dated November 30, 2016 allowed for the indefinite carry forward of tax losses, whereas previously carry forward of tax losses was restricted to 10 years. Also the law specified that tax base for the years 2017-2020 may not be reduced by tax losses carried forward for the amount exceeding 50% of the base.

3.     Dividends

        As a leading telecommunications group with a home base in developing markets, MTS' primary need is to maintain sufficient resources and flexibility to meet financial and operational requirements. At the same time, the Group continually seeks ways to create shareholder value through both its commercial and financial strategies, including organic and non organic development as well as the Group's capital management practices.

        MTS continues to include dividend payments as part of its commitment to maximizing shareholder value. Decisions on dividends are proposed by the Board of Directors and voted upon thereafter at a general meeting of shareholders. In determining the Company's dividend payout, the Board of Directors considers a variety of factors, including:

•

Macroeconomic factors and levels of competitiveness in core markets,



•

Cash flow from operations,



•

The outlook for earnings growth,



•

Capital expenditure requirements,



•

Potential acquisition opportunities,



•

The state of capital markets and the Group's liquidity position, and

26. SEGMENT INFORMATION (Continued)

        Moscow fixed line:    represents the results of fixed line operations carried out in Moscow by the Group's subsidiary MGTS. MGTS is the only licensed public switched telephone network ("PSTN") operator in Moscow and is considered a natural monopoly under Russian antimonopoly regulations. Consequently, substantial part of services provided by MGTS are subject to governmental regulation.

        Ukraine:    represents the results of mobile and fixed line operations carried out across multiple regions of Ukraine.

        The "Other" category does not constitute a reportable segment. It includes the results of a number of other operating segments that do not meet the quantitative thresholds for separate reporting, such as Turkmenistan, Armenia, System Integrator, Satellite TV, Navigation Information Systems, Metro-Telecom, Stream, NVision Czech Republic, Litebox, eSports and Belarus.

        In 2017, management has started internally assess Russia convergent and NVision Czech Republic, Stream, Navigation Information Systems and Metro-Telecom separately in order to monitor the results and make funding decisions on this basis, and thus has presented them separately. Related financial information was, retrospectively, restated.

        The results of operations of UMS are reported as discontinued operations in the accompanying consolidated statements of profit or loss. The segment reporting for the year ended December 31, 2015 was restated accordingly. The consolidated statement of financial position is not required to be retrospectively restated with respect to discontinued operations and therefore as of December 31, 2015 statement of financial position captions in the "Other" category of the following presentation includes UMS.

29. OPERATIONS IN TURKMENISTAN

        In September 2017, the Group's subsidiary in Turkmenistan MTS-TM suspended the provision of telecommunication services to its subscribers, due to the termination by Turkmen state-owned companies and state authorities of line rental, frequency allocation, interconnect, and other agreements necessary to servicing MTS clients. However, the license for the provision of telecommunication services on the Turkmenistan territory is valid till the end of July 2018.

        According to the IAS 36 (par.12) the Group considered facts described above as an impairment indicators and consequently determined that all long-lived assets attributable to Turkmenistan subsidiary were impaired. The Group also assessed the recoverability of the current assets and recorded a provision for those that were considered to be impaired. No indicators of impairment were identified in respect of cash and cash equivalents attributable to MTS-TM. Total impairment charges recognized in the Group's consolidated statement of profit or loss for the year ended December 31, 2017 were as follows:

30. COMMITMENTS AND CONTINGENCIES

        Capital commitments—As of December 31, 2017, the Group had executed purchase agreements of approximately RUB 33,645 million to acquire property, plant and equipment, intangible assets and costs related thereto.

        Agreement with Apple—In April 2017, the Group entered into an unconditional purchase agreement with Apple Rus LLC ("Purchase agreement") to buy 615 thousand iPhone handsets at list prices at the dates of respective purchases over a period ending June 30, 2019. Pursuant to the agreement the Group is also required to incur certain iPhone advertising and promotion costs. As of December 31, 2017 the Group made 44% of its total purchase installment contemplated by the agreement.

        Operating leases—The Group has entered into non-cancellable agreements to lease space for telecommunications equipment, offices and transmission channels, which expire in various years up to 2099. Rental expenses under the operating leases of RUB 7,705 million, RUB 7,581 million and RUB 6,093 million for the years ended December 31, 2017, 2016 and 2015, respectively, are included in selling, general and administrative expenses in the accompanying consolidated statement of profit or loss.

in cost of services in the accompanying consolidated statement of profit or loss. Future minimum lease payments due under these leases at December 31, 2017 are as follows:

        Taxation—Russia and other CIS countries currently have a number of laws related to various taxes imposed by both federal and regional governmental authorities. Applicable taxes include VAT, corporate income tax (profits tax), a number of turnover-based taxes, and payroll (social) taxes. Laws related to these taxes have not been in force for significant periods, in contrast to more developed market economies; therefore, the government's implementation of these regulations is often inconsistent or non-existent. Accordingly, few precedents with regard to tax rulings have been established. Tax declarations, together with other legal compliance areas (for example, customs and currency control matters), are subject to review and investigation by a number of authorities, which are enabled by law to impose extremely severe fines, penalties and interest charges. These facts create tax risks in Russia and the CIS countries that are more significant than those typically found in countries with more developed tax systems.

        Generally, according to Russian and Ukrainian tax legislation, tax declarations remain open and subject to inspection for a period of three years following the tax year. As of December 31, 2017, tax declarations of MTS PJSC and other subsidiaries in Russia and Ukraine for the preceding three fiscal years were open for further review.

        In 2017, the Russian tax authorities completed a tax audit of MTS PJSC for the years ended December 31, 2015 and 2014. No issues that could result in additional significant charges identified.

        Pricing of goods and services provided within the Group is subject to transfer pricing rules.

        Management believes that it has adequately provided for tax liabilities in the accompanying consolidated financial statements. However, the risk remains that the relevant tax authorities could take different positions with regard to interpretive issues and the effect could be significant.

        The Group assessed the following contingent liabilities in respect of additional tax settlements:

30. COMMITMENTS AND CONTINGENCIES (Continued)

        Licenses—In May 2007, the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media awarded MTS a license to provide 3G services in Russia. The 3G license was granted subject to certain capital and other commitments.

        In July 2012, the Federal Service for Supervision in the Area of Communications, Information Technologies and Mass Media allocated MTS the necessary license and frequencies to provide LTE telecommunication services in Russia. Under the terms and conditions of the LTE license, the Group is obligated to fully deploy LTE networks within seven years, commencing from January 1, 2013, and deliver LTE services in each population center with over 50,000 inhabitants in Russia by 2019. Also, the Group is obligated to invest at least RUB 15 billion annually toward the LTE roll-out until the network is fully deployed.

        In March 2015, MTS-Ukraine acquired a nationwide license for the provision of UMTS (3G) telecommunications services through an open tender. The license cost UAH 2,715 million (RUB 6,015 million at the acquisition date) and was granted for 15 years. In accordance with the terms of the license, MTS-Ukraine was required to launch UMTS services in Ukraine by October 2016, and provide coverage throughout Ukraine by April 2020.

        In accordance with the terms of the license, MTS-Ukraine also concluded agreements to convert the provided frequencies for commercial use with the Ministry of Defense of Ukraine, Ministry of Internal Affairs of Ukraine and State Service of Special Communications and Information Protection of Ukraine. For the conversion of frequencies, MTS-Ukraine paid UAH 358 million (RUB 865 million as of the payment date) in 2015 and UAH 299 million (RUB 645 million as of the payment date) in 2017, and is liable to pay UAH 232 million (RUB 476 million as of December 31, 2017) adjusted for the rate of inflation in 2018.

        Management believes that as of December 31, 2017, the Group is in compliance with conditions of the aforementioned licenses.

        Litigation—In the ordinary course of business, the Group is party to various legal, tax and customs proceedings, and subject to claims, some of which relate to developing markets and evolving fiscal and regulatory environments within MTS's markets of operation.

        In August 2017, Federal Antimonopoly Service of the Russian Federation (FAS Russia) has charged MTS with violation of antimonopoly laws in respect to establishing and maintaining monopolistically high prices for communication services in national roaming. In Febraury 2018 FAS Russia found MTS responsible for the aforementioned violation. An administrative case is expected to be initiated, which will result in an administrative fine imposed on MTS in the amount of illegally obtained income.

        The amount of illegally obtained income is determined as the difference between the amount of revenue received by MTS as a result of applying monopolistically high prices and the amount of revenue that could be received as a result of applying prices which are considered by FAS Russia reasonable.

        As there is no information regarding the level of prices that FAS Russia considers economically justified, it is not possible to make a reliable estimation of the adverse effects of the fine that will be potencially imposed.

30. COMMITMENTS AND CONTINGENCIES (Continued)

        Potential adverse effects of economic instability and sanctions in Russia—In 2014 political and economic sanctions targeting certain Russian economic sectors were introduced by the EU, US and other countries. Sanctions were subsequently extended and there is significant uncertainty regarding the extent and timing of further sanctions. Also, Russian Ruble has materially depreciated against the U.S. Dollar and Euro and ruble interest rates have increased significantly after the Central Bank of Russia raised its key rate to 17% in December, 2014. In 2018 due to Russia's ability to remain stable amid severe external shocks Russia sovereign credit ratings were increased from "stable" to "positive". The Central Bank of Russia has gradually decreased its key rate to 7.75% as of December 31, 2017 and subsequently to 7.50% as of February 12, 2018.

        These factors resulted in a lower cost of capital and a stable rate of inflation. However, in Russia there is an uneven growth dynamics, which could have a negative impact on the Group's business including ability to obtain financing on commercially reasonable terms. Management believes it is appropriately acting to support the sustainability of the Group's business in the current circumstances. The Group has a hedging policy in place, which partly mitigated variability of cash outflows, denominated in foreign currencies.

        Political and economic crisis in Ukraine—During the year ended December 31, 2014, a deterioration in the political environment of Ukraine has led to general instability, economic deterioration and armed conflict in eastern Ukraine. In 2014 The National Bank of Ukraine ("NBU") passed a decree prohibiting Ukrainian companies to pay dividends to foreign investors. The decree was extended for a few times and its edition effective as of December 31, 2017 allows payment of dividends from the profit earned in 2014-2015, subject to certain restrictions, as well as payment of the whole amount of dividends accrued from the profit earned before 2014 that was earlier prohibited

        Furthermore, since 2014 the Group established a provision in respect of cash balances in several Ukrainian banks, whose liquidity was affected by the economic downturn. For the year ended December 31, 2015 the provision amounted to RUB 1,698 million and was included as a component of operating expenses in the accompanying consolidated statement of profit or loss.

        The Group believes that these circumstances, despite the recent improvement, combined with political and economic instability in the country, could result in further negative impact on the Group's business including financial position and results of operations.

        As of December 31, 2017, the Group held RUB 1,330 million in current accounts and deposits in Ukrainian banks.

        Anti-terror law—On July 7, 2016 a series of anti-terror laws (also known as "Yarovaya-Ozerov bundle of laws") was enacted by the signature of the President of Russia. In general terms, the laws mandate that operators store and record phone conversations, text messages of subscribers, images, sounds, video and other types of communications by telecommunications operators for defined periods of time. These requirements are to become effective starting July 1, 2018. Compliance with the laws may require the construction of additional storage, processing and indexing centers and a significant increase in the Group capital expenditures. This may adversely impact Group's financial indicators, in particular free cash flow.

        The requirements of the anti-terror laws in respect of the data storage volume are to be determined by legal acts that have not been adopted yet. The Group will estimate the potential impact of the laws on the Group's consolidated financial statements, including additional provisions, once requirements are approved and come into force.

        Investigations into former operations in Uzbekistan—In March 2014, the Group received requests for the provision of information from the United States Securities and Exchange Commission ("SEC") and the United States Department of Justice ("DOJ") relating to a currently conducted investigation of the Group's former subsidiary in Uzbekistan.

        In 2015, activities related to the Group's former operations in Uzbekistan have been referenced in a civil forfeiture complaints ("The Complaints"), filed by DOJ in the U.S. District Court, Southern District of New York (Manhattan), directed at certain assets of an unnamed Uzbek government official. The Complaints allege among other things that MTS and certain other parties made corrupt payments to the unnamed Uzbek official to assist their entering and operating in the Uzbekistan telecommunications market. The Complaints are solely directed towards assets held by the unnamed Uzbek official, and none of MTS's assets are affected by the Complaints.

        The Group continues to cooperate with these investigations. The Group, the DOJ and the SEC are having discussions about a potential resolution to allegations of non-compliance with the Foreign Corrupt Practices Act (FCPA). However, at this stage, the Group is unable to predict whether or not such discussions will result in a settled resolution to the investigations, the magnitude of any settlement, or whether there will be further developments in the investigations.

31. SUBSEQUENT EVENTS

        4G license secured by Vodafone Ukraine—In January and March 2018, VF Ukraine PrJSC, which serves the Ukraine market and operates as Vodafone Ukraine, secured a 4G licenses in the 2510-2520 / 2630-2640 and 1780-1785 / 1875-1880 MHz bands as the result of a national auction. The first 4G launch in Ukraine's largest cities could take place by the end of March 2018.

        Acquisition of MDTZK LLC and Kulturnaya Sluzhba LLC—In the first quarter of 2018, the Group acquired 100% stake in MDTZK LLC (operating under the trademark Ticketland.ru) and a 78.2% stake in Kulturnaya Sluzhba LLC (operating under the trademark Ponominalu.ru), the leading players in the Russian e-ticketing industry. The acquisitions allow MTS to enter the event ticket market (both online and offline) and establish itself as a leading ticket operator in Russia, while broadening MTS's suite of digital services and integrating a key new product into its existing loyalty program and mobile app ecosystem. See Note 4 for further information.

        Early repayment of credit facilities—In March 2018, MTS made partial early repayment of the 10-year credit facility from Calyon, ING Bank N.V., Nordea Bank AB and Raiffeisen Zentralbank Osterreich AG in the amount of USD 224.7 million (RUB 12,668 million). The early repayment of the loan is a part of the Company's debt portfolio optimization strategy aimed at decreasing of the overall cost of debt and increasing its overall tenor.
