The following table presents our selected consolidated balance sheet data as of December 31, 2014, 2015, 2016, 2017 and 2018.

Changing in Reporting Currency and Exchange Rate Information

Our business is primarily conducted in China and almost all of our revenues are denominated in RMB. Effectively from the fourth quarter of 2018, we changed our reporting currency from U.S. dollar to RMB. The change in reporting currency is to improve investors’ ability to evaluate our financial results against other comparable publicly traded companies in the industry. Prior to the fourth quarter of 2018, we reported our annual and quarterly consolidated balance sheets and consolidated statements of income and comprehensive income and shareholder’s equity and cash flows in U.S. dollar. In this annual report, the financial results for the year ended December 31, 2018 are stated in RMB. The related financial statements prior to the current period have been recast to reflect RMB as the reporting currency for comparison to the financial results for the year ended December 31, 2018.

Current period amounts in this annual report are translated into U.S. dollars for the convenience of the readers. The conversion of RMB into U.S. dollars in this annual report is based on the noon buying rate in New York City for cable transfers in RMB as certified for customs purposes by the Federal Reserve Board. Unless otherwise stated, all translations of RMB into U.S. dollars were made at the rate at RMB6.8755 to US$1.00, the exchange rate as set forth in the H.10 statistical release of the Board of Governors of the Federal Reserve System in effect as of December 31, 2018. We make no representation that any RMB or U.S. dollar amounts could have been, or could be, converted into U.S. dollars or RMB, as the case may be , at any particular rate, or at all. The PRC government imposes control over its foreign currency reserves in part through direct regulation of the conversion of RMB into foreign exchange and through restrictions on foreign trade.

Risks Related to Our Business and Industry

If we fail to retain our existing users, further grow our user base, or if user engagement on our platform declines, our business and operating results may be materially and adversely affected.

The size of our user base and the level of our user engagement are critical to our success. Although our MAUs generally grew over time since our inception, there were times when our user base failed to grow as we expected. For example, the growth rate of our MAUs significantly decreased in 2015 primarily due to the reduced growth of number of smartphone users in China, and upgrades to our platform that were difficult for some of our users to adapt to. There is no guarantee that our MAUs will continue to grow at a desirable rate or at all. Growing our user base and increasing the overall level of user engagement on our social networking platform and in particular our live video service, which currently contributes a majority of our revenues, are critical to our business. If our user growth rate slows down, as it did in 2015, our success will become increasingly dependent on our ability to retain existing users and enhance user engagement on our platform. If our Momo mobile application is no longer one of the social networking tools that people frequently use, or if people do not perceive our services to be interesting or useful, we may not be able to attract users or increase the frequency or degree of their engagement. A number of user-oriented instant communication products that achieved early popularity have since seen the size of their user base or level of user engagement decline, in some cases precipitously. There is no guarantee that we will not experience a similar erosion of our user base or user engagement level in the future. A number of factors could negatively affect user retention, growth and engagement, including if:

If we are unable to grow our user base or enhance user engagement, our platform will become less attractive to our users, customers and platform partners, which would have a material and adverse impact on our business and operating results.

We cannot guarantee that the monetization strategies we have adopted will be successfully implemented or generate sustainable revenues and profits.

As online social networking and online entertainment industries in China are relatively young, prevailing monetization models similar to ours have yet to be proven to be sustainable, and it may be more difficult to predict user and customer behaviors and demands compared to other established industries. Our monetization model has been evolving. We began to generate revenues in the second half of 2013 primarily through membership subscriptions and also game publishing and other services, but we continue to explore and implement new monetization models. While membership subscriptions contributed a majority of our revenues prior to 2016, live video service, which we launched in September 2015 and adopted a virtual items-based revenue model, has replaced membership subscription as our major source of revenues in 2016, 2017 and 2018. The services that we currently provide, including live video service, value-added service (comprising membership subscriptions and virtual gift service), mobile marketing services, mobile games, and other services, contributed approximately 79.9%, 14.0%, 3.7%, 1.0% and 1.4%, respectively, of our net revenues in 2018. Apart from live video services, from time to time we have launched new services on our platform, explored new monetization models and broadened our revenue sources, and we expect to continue to do so. For example, in February 2015, we launched our first self-developed game on our platform, which generated revenues through in-game purchases of virtual items. In the second quarter of 2015, we launched our in-feed marketing solutions powered by a proprietary self-served advertising system, and started to offer brand-oriented display ads and action-driven ad products such as app downloads. In the fourth quarter of 2016, we launched a virtual gift service which allows our users to purchase and send virtual gifts to other users outside of live video service. In 2018, we produced a television program. However, there is no assurance that any of these and other new monetization models would be profitable or sustainable. If our strategic initiatives do not enhance our ability to monetize our existing services or enable us to develop new approaches to monetization, we may not be able to maintain or increase our revenues and profits or recover any associated costs.

5

We may in the future introduce new services to further diversify our revenue streams, including services with which we have little or no prior development or operating experience. If these new or enhanced services fail to engage users, customers or platform partners, we may fail to attract or retain users or to generate sufficient revenues to justify our investments, and our business and operating results may suffer as a result.

We operate in a highly dynamic market, which makes it difficult to evaluate our future prospects.

The market for social networking platforms is relatively new, highly dynamic and may not develop as expected. Our users, customers and platform partners may not fully understand the value of our services, and potential new users, customers and platform partners may have difficulty distinguishing our services from those of our competitors. Convincing potential users, customers and platform partners of the value of our services is critical to the growth of our user base and the success of our business.

We launched our Momo mobile application in August 2011. The operating history and our evolving monetization strategies make it difficult to assess our future prospects or forecast our future results. You should consider our business and prospects in light of the risks and challenges we encounter or may encounter in this developing and rapidly evolving market. These risks and challenges include our ability to, among other things:

If we fail to educate potential users, customers and platform partners about the value of our services, if the market for our platform does not develop as we expect or if we fail to address the needs of this dynamic market, our business will be harmed. Failure to adequately address these or other risks and challenges could harm our business and cause our operating results to suffer.

6

We currently generate a substantial majority of our revenues from our live video service. We may not be able to continue to grow or continue to achieve profitability from such service.

In September 2015, we launched our live video service with a virtual items-based revenue model, whereby users can enjoy live performances and interact with the broadcasters for free, and have the option of purchasing in-show virtual items. We have achieved initial success for this service, which contributed RMB2,534.6 million, RMB7,429.9 million and RMB10,709.5 million (US$1,557.6 million) to, or 68.4%, 83.6% and 79.9% of, our net revenues in 2016, 2017 and 2018, respectively. While we plan to continue to invest significantly in expanding our live video service, we may not be able to continue to achieve the level of profitability based on the virtual items-based revenue model, as we have limited experience in operating such service. In addition, popular broadcasters or talent agencies may cease to use our service and we may be unable to attract new talents that can attract users or cause such users to increase the amount of time spent on our platform or the amount of money spent on in-show virtual items.

Although we believe we have a large and diversified pool of talented broadcasters, talent agencies as well as paying users (which allows us to manage the risk of revenue concentration) and have entered into multi-year exclusivity agreements with popular broadcasters, if a large number of our broadcasters, particularly popular broadcasters, were to leave our platform for competing platforms at the same time, if we are unable to negotiate acceptable business terms with popular broadcasters or talent agencies, or if a large number of our users decided to use live video services provided by our competitors, we might not be able to expand the user base of our live video service and achieve or maintain the level of revenues and profitability as we currently anticipate. Broadcasters provide live video service on our platform as an individual or as a member of a talent agency. The talent agencies recruit, train and retain the broadcasters. We are committed to provide strong support and resources to broadcasters and talent agencies to offer high-quality content. We are also committed to closely cooperate and develop long-term relationship with broadcasters and talent agencies. However, under our current arrangements with our broadcasters and talent agencies, we share with them a portion of the revenues we derive from the sales of in-show virtual items in our live video service. Payments of revenue sharing to broadcasters and talent agencies for our live video service constitute a major portion of our cost of revenues. If we are required to share a larger portion of our revenues with the broadcasters and talent agencies for competition purpose, our results of profitability may be adversely impacted.

We may not be able to successfully maintain and increase the number of paying users for the various services we offer on our platform.

Our future growth depends on our ability to convert our users into paying users of our services, including live video service, value-added service, mobile games and other services, and our ability to retain our existing paying users. However, we cannot assure you that we will be successful in any of the foregoing initiatives, nor can we assure you that we will be able to successfully compete with current and new competitors on attracting paying users. We had 17.7 million paying users in 2018 for our live video service and value-added services on Momo application, compared to 13.7 million in 2017 and 8.0 million in 2016 without double counting the overlap of each year. We also had 4.1 million paying users on Tantan application from June 1, 2018 to December 31, 2018. Our efforts to provide greater incentives for our users to pay for our various services may not continue to succeed. Our paying users may discontinue their spending on our services because they may no longer serve our paying users’ needs, or simply because the interests and preferences of these users shift. If we cannot successfully maintain or increase the number of our paying users, our business, results of operations and prospects will be adversely affected.

The loss of marketers, or reduction in spending by marketers, could harm our business.

Our mobile marketing services generated 11.9%, 5.8% and 3.7% of our revenues in 2016, 2017 and 2018, respectively. Currently our mobile marketing services primarily comprise in-feed marketing solutions and brand-oriented display ads. As is common in the industry, our marketers do not have long-term advertising commitments with us. Many of our marketers spend only a relatively small portion of their overall advertising budgets with us. In addition, marketers may view some of our products as experimental and unproven. Marketers may not continue to do business with us, or they may advertise with us based on terms unfavorable to us, if we do not deliver our marketing solutions in an effective manner, or if they do not believe that their investment in advertising with us will generate a competitive return relative to other alternatives. For example, failure to maintain or increase the quantity or quality of ads shown to users, or a decrease in user engagement may cause marketers to reduce or cease their spending on our mobile marketing services.

7

Our business is dependent on the strength of our brands and market perception of our brand.

In China, we market our services under the brands “陌陌” or “Momo” and “探探” or “Tantan.” Our business and financial performance are highly dependent on the strength and the market perception of our brands and services. A well-recognized brand is critical to increasing our user base and, in turn, facilitating our efforts to monetize our services and enhancing our attractiveness to customers. From time to time, we conduct marketing activities across various media to enhance our brands and to guide public perception of our brands and services. In order to create and maintain brand awareness and brand loyalty, to influence public perception and to retain existing and attract new mobile users, customers and platform partners, we may need to substantially increase our marketing expenditures. We cannot assure you, however, that these activities will be successful or that we will be able to achieve the brand promotion effect we expect.

In addition, people may not understand the value of our platform, and there may be a misperception that Momo is used solely as a tool to randomly meet or date strangers. Convincing potential new users, customers and platform partners of the value of our services is critical to increasing the number of our users, customers and platform partners and to the success of our business.

Content posted or displayed on our social networking platform, including the live video shows hosted by us or our users, may be found objectionable by PRC regulatory authorities and may subject us to penalties and other severe consequences.

The PRC government has adopted regulations governing internet and wireless access and the distribution of information over the internet and wireless telecommunications networks. Under these regulations, internet content providers and internet publishers are prohibited from posting or displaying over the internet or wireless networks content that, among other things, violates the principle of the PRC constitution, laws and regulations, impairs the national dignity of China or the public interest, or is obscene, superstitious, fraudulent or defamatory. Furthermore, internet content providers are also prohibited from displaying content that may be deemed by relevant government authorities as instigating ethnical hatred and harming ethnical unity, harming the national religious policy, “socially destabilizing” or leaking “state secrets” of the PRC. Failure to comply with these requirements may result in the revocation of licenses to provide internet content or other licenses, the closure of the concerned platforms and reputational harm. The operator may also be held liable for any censored information displayed on or linked to their platform.

We have designed and implemented procedures to monitor content on our social networking platform, including the live video shows hosted by us or our users, in order to comply with relevant laws and regulations. However, it may not be possible to determine in all cases the types of content that could result in our liability as a distributor of such content and, if any of the content posted or displayed on our social networking platform is deemed by the PRC government to violate any content restrictions, we would not be able to continue to display such content and could become subject to penalties, including confiscation of income, fines, suspension of business and revocation of required licenses, which could materially and adversely affect our business, financial condition and results of operations.

We may also be subject to potential liability for any unlawful actions by our users on our platform. It may be difficult to determine the type of content or actions that may result in liability to us and, if we are found to be liable, we may be prevented from operating our business in China. Moreover, the costs of compliance with these regulations may continue to increase as a result of more content being made available by an increasing number of users of our social networking platform, which may adversely affect our results of operations. Although we have adopted internal procedures to monitor content and to remove offending content once we become aware of any potential or alleged violation, we may not be able to identify all the content that may violate relevant laws and regulations or third-party intellectual property rights. Even if we manage to identify and remove offensive content, we may still be held liable.

Our acquisition of Tantan, and the subsequent integration of Tantan into our business, creates significant challenges which may affect our ability to realize the benefits of the acquisition and have a material adverse effect on our business, reputation, results of operations and financial condition.

In May 2018, we completed the acquisition of Tantan, a Chinese social and dating app for approximately 5.3 million newly issued Class A ordinary shares of the Company and US$613.2 million in cash. While we currently expect Tantan to remain a stand-alone brand and to largely operate independently, the process of integrating certain aspects of Tantan’s operations into our own operations is still continuing and could result in unforeseen operating difficulties, divert significant management attention and require significant resources that would otherwise have been available for the ongoing development of our existing operations. Challenges and risks from the Tantan acquisition include, among others:

8

Moreover, we may not be able to achieve our intended strategic goals or attain the synergies from the transaction. If we are unable to successfully integrate Tantan and manage the larger business, or are unable to achieve the expected benefits of the transaction, we may be required to record substantial impairment charges to goodwill. Any such negative development could have a material adverse effect on our business, reputation, results of operations and financial condition.

The mobile social and dating industry is an evolving and competitive market, with low switching costs and a consistent stream of new products and entrants, and innovation by Tantan’s competitors may disrupt its business.

The mobile social and dating industry in China is evolving and competitive, and has experienced a consistent stream of new products and market entrants within recent years. Tantan’s competitors may hold a stronger competitive positions in certain geographical regions or with certain user demographics that we currently serve or may serve in the future. These advantages could enable these competitors to offer features and services that are more appealing to current users and potential users than our features and services or to respond more quickly and/or cost-effectively than us to new or changing opportunities.

In addition, within the mobile social and dating industry generally, costs for consumers to switch between products and apps are low, and consumers have demonstrated a propensity to try new approaches to connecting with people. As a result, new products, entrants and business models are likely to continue to emerge. It is possible that a new app could gain rapid scale at the expense of existing brands through harnessing a new technology or distribution channel, creating a new approach to connecting people or some other means. If we are not able to compete effectively against our current or future competitors and other apps, products and services that may emerge, the size and level of engagement of our user base may decrease, which could have a material adverse effect on our business, financial condition and results of operations.

We may be unsuccessful in monetizing Tantan’s social and dating services.

Tantan is a relatively new mobile social and dating app with a limited operating history and track record of monetization of its services. The success of the Tantan acquisition will be significantly affected by our ability to continue to grow the monetization of Tantan. However, we may be unable to do so due to, among other reasons, Tantan’s users ceasing to use mobile technology for dating and socializing, Tantan’s users opting to forgo paid services on the app, perceived or actual privacy concerns, the introduction of new regulations on the use and monetization of user data, and the introduction of competition offering lower cost services or additional or different features. If we are unable to successfully monetize Tantan’s business, we may be unable to achieve the expected benefits of the Tantan acquisition, which could have a material adverse effect on our business, reputation, results of operations and financial condition.

9

Tantan’s growth and profitability rely, in part, on its ability to attract and retain users, which involves considerable expenditure. Any failure in these efforts could adversely affect our business, financial condition and results of operations.

Tantan commenced monetization of its business in July 2017, and historically has not been profitable. In order to continue to grow its business and eventually become profitable, Tantan will need to continue to attract and retain users for Tantan’s app, which will involve considerable expenditures. Historically, Tantan has had to increase its selling and marketing expenses over time in order to attract and retain users and sustain its growth in users.

Tantan’s marketing expenditures consist primarily of investments in paid marketing channels to acquire more users and drive traffic to the app. To continue to reach potential users and grow the Tantan business, we must identify and devote more of Tantan’s overall marketing expenditures to new and evolving marketing channels, which may include mobile and virtual platforms. The opportunities in and sophistication of newer marketing channels generally are relatively undeveloped and unproven, making it difficult to assess returns on investment associated with such channels, and there can be no assurance that we will be able to continue to appropriately manage and fine-tune our marketing efforts in response to these and other trends in the industry. Any failure to do so could have a material adverse effect on our business, reputation, results of operations and financial condition.

Negative publicity may harm our brand and reputation and have a material adverse effect on our business and operating results.

Negative publicity involving us, our users, our management, our social networking platform or our business model may tarnish our reputation and materially and adversely harm our brand and our business. We cannot assure you that we will be able to defuse negative publicity about us, our management and/or our services to the satisfaction of our investors, users, customers and platform partners. There has been negative publicity about our company and the misuse of our services, which has adversely affected our brand, public image and reputation. Such negative publicity, especially when it is directly addressed against us, may also require us to engage in defensive media campaigns. This may cause us to increase our marketing expenses and divert our management’s attention and may adversely impact our business and results of operations.

Any legal action, regardless of its merits, could be time consuming and could divert the attention of our management away from our business and a failure of any legal action may bring negative impact on our reputation and cause a loss of our brand equity, which would reduce the use of our platform and demand for our services. Moreover, any attempts to rebuild our reputation and restore the value of our brand may be costly and time consuming, and such efforts may not ultimately be successful.

User misconduct and misuse of our platform may adversely impact our brand image, and we may be held liable for information or content displayed on, retrieved from or linked to our platform, which may materially and adversely affect our business and operating results.

Our platform allows mobile users to freely contact and communicate with people nearby, and our live video service allows users to host and view live shows. Because we do not have full control over how and what users will use our platform to communicate, our platform may be misused by individuals or groups of individuals to engage in immoral, disrespectful, fraudulent or illegal activities. For example, on a daily basis we detect spam accounts through which illegal or inappropriate content is posted and illegal or fraudulent activities are conducted. Media reports and internet forums have covered some of these incidents, which have in some cases generated negative publicity about our brand and platform. We have implemented control procedures to detect and block illegal or inappropriate content and illegal or fraudulent activities conducted through the misuse of our platform, but such procedures may not prevent all such content from being broadcasted or posted or activities from being carried out. Moreover, as we have limited control over real-time and offline behaviors of our users, to the extent such behaviors are associated with our platform, our ability to protect our brand image and reputation may be limited. Our business and the public perception of our brand may be materially and adversely affected by misuse of our platform.

In addition, if any of our users suffers or alleges to have suffered physical, financial or emotional harm following contact initiated on our platform, we may face civil lawsuits or other liabilities initiated by the affected user, or governmental or regulatory actions against us. In response to allegations of illegal or inappropriate activities conducted through our platform or any negative media coverage about us, PRC government authorities may intervene and hold us liable for non-compliance with PRC laws and regulations concerning the dissemination of information on the internet and subject us to administrative penalties or other sanctions, such as requiring us to restrict or discontinue some of the features and services provided on our mobile application. Therefore, our business may be subject to investigations or subsequent penalties if contents generated by our users are deemed to be illegal or inappropriate under PRC laws and regulations. See “—Risks Related to Doing Business in China—If we fail to obtain and maintain the requisite licenses and approvals required under the complex regulatory environment applicable to our businesses in China, or if we are required to take compliance actions that are time-consuming or costly, our business, financial condition and results of operations may be materially and adversely affected.” As a result, our business may suffer, our user base, revenues and profitability may be materially and adversely affected, and the price of our ADSs may decline.

10

The market in which we operate is fragmented and highly competitive. If we are unable to compete effectively for users or user engagement, our business and operating results may be materially and adversely affected.

As a social networking platform that provides multiple services, including live video service, value-added service, mobile marketing services and other services, we are subject to intense competition from providers of similar services, as well as potential new types of online services. Our competitors may have substantially more cash, traffic, technical, broadcasters, business networks and other resources, as well as broader product or service offerings and can leverage their relationships based on other products or services to gain a larger share of marketing budgets. We may be unable to compete successfully against these competitors or new market entrants, which may adversely affect our business and financial performance.

We believe that our ability to compete effectively depends upon many factors both within and beyond our control, including:

If we fail to keep up with technological developments and evolving user expectations, we may fail to maintain or attract users, customers or platform partners, and our business and operating results may be materially and adversely affected.

We operate in a market characterized by rapidly changing technologies, evolving industry standards, new product and service announcements, new generations of product enhancements and changing user expectations. Accordingly, our performance and the ability to further monetize the services on our platform will depend on our ability to adapt to these rapidly changing technologies and industry standards, and our ability to continually innovate in response to both evolving demands of the marketplace and competitive services. There may be occasions when we may not be as responsive as our competitors in adapting our services to changing industry standards and the needs of our users. Historically, new features may be introduced by one player in the industry, and if they are perceived as attractive to users, they are often quickly copied and improved upon by others.

Introducing new technologies into our systems involves numerous technical challenges, substantial amounts of capital and personnel resources and often takes many months to complete. For example, the market for mobile devices in China is highly fragmented, and the lower resolution, functionality, operating system compatibility and memory currently associated with the kaleidoscopic models of mobile devices in the Chinese marketplace may make the use of our services through these devices more difficult and impair the user experience. We intend to continue to devote resources to the development of additional technologies and services. We may not be able to effectively integrate new technologies on a timely basis or at all, which may decrease user satisfaction with our services. Such technologies, even if integrated, may not function as expected or may be unable to attract and retain a substantial number of mobile device users to use our Momo mobile application. We also may not be able to protect such technology from being copied by our competitors. Our failure to keep pace with rapid technological changes may cause us to fail to retain or attract users or generate revenues, and could have a material and adverse effect on our business and operating results.

11

If we fail to effectively manage our growth and control our costs and expenses, our business and operating results could be harmed.

We have experienced rapid growth in our business and operations and expansion of our platform since our inception in 2011, which places significant demands on our management, operational and financial resources. However, given the rapidly evolving market in which we compete, we may encounter difficulties as we establish and expand our operations, product development, sales and marketing, and general and administrative capabilities. We face significant competition for talented employees from other high-growth companies, which include both publicly traded and privately held companies, and we may not be able to hire new talents quickly enough to meet our needs and support our operations. If we fail to effectively manage our hiring needs and successfully integrate our new hires, our efficiency and ability to meet our forecasts and our employee morale, productivity and retention could suffer, and our business and operating results could be adversely affected.

We expect our costs and expenses to continue to increase in the future as we seek to broaden our user base and increase user engagement, and develop and implement new features and services. In addition, our cost and expenses, such as our research and development expenses, sales and marketing expenses and general and administrative expenses, have grown rapidly as we expanded our business. Historically, our costs and expenses have increased each year, and we expect to continue to incur increasing costs and expenses to support our anticipated future growth. Continued growth could also strain our ability to maintain reliable service levels for our users and customers, develop and improve our operational, financial, legal and management controls, and enhance our reporting systems and procedures. If we are unable to generate adequate revenues and to manage our expenses, we may again incur significant losses in the future and may not be able to maintain profitability. Our expenses may grow faster than our revenues, and our expenses may be greater than we anticipate. Managing our growth will require significant expenditures and the allocation of valuable management resources. If we fail to achieve the necessary level of efficiency in our organization as we grow, our business, operating results and financial condition could be harmed.

We may not be able to remain profitable, and the consolidation of the results of operations of Tantan with ours may negatively impact our financial performance and results of operations.

We believe that our future revenue growth will depend on, among other factors, the popularity of social networking applications and our ability to attract new users, increase user engagement, effectively design and implement monetization strategies, develop new services and compete effectively and successfully, as well as our ability to successfully monetize Tantan’s operations. In addition, our ability to sustain profitability is affected by various factors, many of which are beyond our control, such as the continuous development of social networking, live video services, mobile marketing services, and mobile games in China. We may again incur losses in the near future due to our continued investments in services, technologies, research and development and our continued sales and marketing initiatives. Changes in the macroeconomic and regulatory environment or competitive dynamics and our inability to respond to these changes in a timely and effective manner may also impact our profitability. Furthermore, we completed our acquisition of Tantan in May 2018, and consolidate Tantan’s results starting in the second quarter of 2018. Tantan commenced monetization of its business in July 2017 and historically has not been profitable. If Tantan continues to incur losses, this may also affect our ability to remain profitable. Accordingly, you should not rely on the revenues of any prior quarterly or annual period as an indication of our future performance.

Privacy concerns relating to our services and the use of user information could negatively impact our user base or user engagement, or subject us to governmental regulation and other legal obligations, which could have a material and adverse effect on our business and operating results.

We collect user profile, user location and other personal data from our users in order to better understand our users and their needs and to support our social interest graph engine and our big data analytical capabilities for more targeted services such as interest- or location-based user groups and mobile marketing services. Concerns about the collection, use, disclosure or security of personal information, chat history or other privacy-related matters, even if unfounded, could damage our reputation, cause us to lose users, customers and platform partners and subject us to regulatory investigations, all of which may adversely affect our business. While we strive to comply with applicable data protection laws and regulations, as well as our privacy policies pursuant to our terms of use and other obligations we may have with respect to privacy and data protection, any failure or perceived failure to comply with these laws, regulations or policies may result, and in some cases have resulted, in inquiries and other proceedings or actions against us by government agencies or others, as well as negative publicity and damage to our reputation and brand, each of which could cause us to lose users, customers and platform partners and have an adverse effect on our business and operating results.

12

Any system failure or compromise of our security that results in the unauthorized access to or release of the data or chat history of our users, customers or platform partners could significantly limit the adoption of our services, as well as harm our reputation and brand. We expect to continue expending significant resources to protect against security breaches. The risk that these types of events could seriously harm our business is likely to increase as we expand the number of services we offer and increase the size of our user base.

Our practices may become inconsistent with new laws or regulations concerning data protection, or the interpretation and application of existing consumer and data protection laws or regulations, which is often uncertain and in flux. If so, in addition to the possibility of fines, this could result in an order requiring that we change our practices, which could have an adverse effect on our business and operating results. For example, the European Union General Data Protection Regulation (“GDPR”), which came into effect on May 25, 2018, includes operational requirements for companies that receive or process personal data of residents of the European Economic Area. The GDPR establishes new requirements applicable to the processing of personal data, affords new data protection rights to individuals and imposes penalties for serious data breaches. Individuals also have a right to compensation under the GDPR for financial or non-financial losses. Although we do not conduct any business in the European Economic Area, in the event that residents of the European Economic Area access our website and input protected information, we may become subject to provisions of the GDPR. Complying with new laws and regulations could cause us to incur substantial costs or require us to change our business practices in a manner materially adverse to our business. See also “—Risks Related to Doing Businesses in China—Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.”

The continuing and collaborative efforts of our senior management and key employees are crucial to our success, and our business may be harmed if we were to lose their services.

We depend on the continued contributions of our senior management, especially the executive officers listed in “Item 6. Directors, Senior Management and Employees—A. Directors and Senior Management” section of this annual report, and other key employees, many of whom are difficult to replace. The loss of the services of any of our executive officers or other key employees could materially harm our business. Competition for qualified talents in China is intense. Our future success is dependent on our ability to attract a significant number of qualified employees and retain existing key employees. If we are unable to do so, our business and growth may be materially and adversely affected and the trading price of our ADSs could suffer. Our need to significantly increase the number of our qualified employees and retain key employees may cause us to materially increase compensation-related costs, including stock-based compensation.

We may not be able to adequately protect our intellectual property, which could cause us to be less competitive and third-party infringements of our intellectual property rights may adversely affect our business.

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. See also “Item 4. Information on the Company—B. Business Overview.” Despite our efforts to protect our proprietary rights, third parties may attempt to copy or otherwise obtain and use our intellectual property or seek court declarations that they do not infringe upon our intellectual property rights. Monitoring unauthorized use of our intellectual property is difficult and costly, and we cannot be certain that the steps we have taken will prevent misappropriation of our intellectual property. From time to time, we may have to resort to litigation to enforce our intellectual property rights, which could result in substantial costs and diversion of our resources.

There have been instances where third parties have cloned and launched counterfeits of our Momo mobile application on app stores or internet forums. Some of these counterfeits, once installed inadvertently by mobile users, were reported to automatically download and install other applications to these users’ mobile phones, charging them various fees. These counterfeits may mislead mobile users and negatively affect their perception of our application. Moreover, we may have to expend resources in connection with any legal actions that we take to curb these counterfeiting activities in order to protect our intellectual property rights, user experience and brand perception.

13

We have been and may be subject to intellectual property infringement claims or other allegations by third parties for information or content displayed on, retrieved from or linked to our platform, or distributed to our users, which may materially and adversely affect our business, financial condition and prospects.

We have been, and may in the future be, subject to intellectual property infringement claims or other allegations by third parties for services we provide or for information or content displayed on, retrieved from or linked to our platform, or distributed to our users, which may materially and adversely affect our business, financial condition and prospects.

Companies in the internet, technology and media industries are frequently involved in litigation based on allegations of infringement of intellectual property rights, unfair competition, invasion of privacy, defamation and other violations of other parties’ rights. The validity, enforceability and scope of protection of intellectual property rights in internet-related industries, particularly in China, are uncertain and still evolving. We have faced, from time to time, and expect to face in the future, allegations that we have infringed the trademarks, copyrights, patents and other intellectual property rights of third parties, including our competitors, or allegations that we are involved in unfair trade practices. For example, on October 22, 2015, we were served a civil complaint by Guangzhou Tian He People’s Court in which the plaintiff claimed that Xiaoyao Xiyou, a game that we previously operated and have ceased operating since November 2017, infringed upon the plaintiff’s copyright in works of literature and art of a game, constituting unfair competition. The plaintiff demanded that we cease the infringement and pay compensation and legal costs totaling approximately RMB10 million (US$1.5 million). On August 31, 2017, Guangzhou Tian He People’s Court ruled a civil judgement of first-instance, which ordered us and the developer of Xiaoyao Xiyou to cease the infringement and pay compensation in the amount of RMB5.0 million (US$0.8 million) to the plaintiff. The developer of Xiaoyao Xiyou filed an appeal to the Guangzhou Intellectual Property Court. On September 27, 2018, Guangzhou Intellectual Property Court ruled a civil judgement of final-instance, which ordered us and the developer of Xiaoyao Xiyou to cease the infringement and pay compensation in the amount of RMB4.0 million (US$0.6 million) to the plaintiff. We paid the compensation in full to the plaintiff on October 10, 2018. The plaintiff filed a re-trial application with the Guangdong Provincial Higher People’s Court for revoking the civil judgement of final-instance ruled by the Guangzhou Intellectual Property Court and remaining the civil judgement of first-instance ruled by the Guangzhou Tian He People’s Court. The re-trail hearing has yet to be carried out as of the date of this annual report. On February 20, 2019, we were served four civil complaints by Shenzhen Intermediate People’s Court in which the plaintiff claimed that our app infringed upon the plaintiff’s four patents. The plaintiff demanded that we cease the infringement and compensate its loss and legal costs totaling approximately RMB 4 million (US$0.6 million) in relation to the four patents under the four complaints. The hearings have yet to be carried out as of the date of this annual report. See “Item 8. Financial Information— A. Consolidated Statements and Other Financial Information—Legal Proceedings.” As we face increasing competition and as litigation becomes a more common method for resolving commercial disputes in China, we face a higher risk of being the subject of intellectual property infringement claims.

We allow users to upload text, graphics, audio, video and other content to our platform and download, share, link to and otherwise access games and other content on our platform. We have procedures designed to reduce the likelihood that content might be used without proper licenses or third-party consents. However, these procedures may not be effective in preventing the unauthorized posting of copyrighted content. Therefore, we may face liability for copyright or trademark infringement, defamation, unfair competition, libel, negligence, and other claims based on the nature and content of the materials that are delivered, shared or otherwise accessed through our platform.

Defending intellectual property litigation is costly and can impose a significant burden on our management and employees, and there can be no assurances that favorable final outcomes will be obtained in all cases. Such claims, even if they do not result in liability, may harm our reputation. Any resulting liability or expenses, or changes required to our platform to reduce the risk of future liability, may have a material adverse effect on our business, financial condition and prospects.

14

User growth and engagement depend upon effective interoperation with mobile operating systems, networks, mobile devices and standards that we do not control.

We make our services available across a variety of mobile operating systems and devices. We are dependent on the interoperability of our services with popular mobile devices and mobile operating systems that we do not control, such as Android, iOS and Windows. Any changes in such mobile operating systems or devices that degrade the functionality of our services or give preferential treatment to competitive services could adversely affect usage of our services. Further, if the number of platforms for which we develop our services increases, which is typically seen in a dynamic and fragmented mobile services market such as China, it will result in an increase in our costs and expenses. In order to deliver high-quality services, it is important that our services work well across a range of mobile operating systems, networks, mobile devices and standards that we do not control. We may not be successful in developing relationships with key participants in the mobile industry or in developing services that operate effectively with these operating systems, networks, devices and standards. In the event that it is difficult for our users to access and use our services, particularly on their mobile devices, our user growth and user engagement could be harmed, and our business and operating results could be adversely affected.

Our operations depend on the performance of the internet infrastructure and fixed telecommunications networks in China.

Almost all access to the internet in China is maintained through state-owned telecommunication operators under the administrative control and regulatory supervision of the Ministry of Industry and Information Technology, or the MIIT. Moreover, we primarily rely on a limited number of telecommunication service providers to provide us with data communications capacity through local telecommunications lines and internet data centers to host our servers. We have limited access to alternative networks or services in the event of disruptions, failures or other problems with China’s internet infrastructure or the fixed telecommunications networks provided by telecommunications service providers. Web traffic in China has experienced significant growth during the past few years. Effective bandwidth and server storage at internet data centers in large cities such as Beijing are scarce. With the expansion of our business, we may be required to upgrade our technology and infrastructure to keep up with the increasing traffic on our platform. We cannot assure you that the internet infrastructure and the fixed telecommunications networks in China will be able to support the demands associated with the continued growth in internet usage. If we cannot increase our capacity to deliver our online services, we may not be able to keep up with the increases in traffic we anticipate from our expanding user base, and the adoption of our services may be hindered, which could adversely impact our business and our ADS price.

In addition, we have no control over the costs of the services provided by telecommunications service providers. If the prices we pay for telecommunications and internet services rise significantly, our results of operations may be materially and adversely affected. Furthermore, if internet access fees or other charges to internet users increase, some users may be prevented from accessing the mobile internet and thus cause the growth of mobile internet users to decelerate. Such deceleration may adversely affect our ability to continue to expand our user base.

Our business and operating results may be harmed by service disruptions, cybersecurity related threats or by our failure to timely and effectively scale and adapt our existing technology and infrastructure.

People use our platform for real-time communication, socializing, entertainment and information. We have experienced, and may in the future experience, service disruptions, outages and other performance problems due to a variety of factors, including infrastructure changes and cybersecurity related threats as follows:

15

Any disruption or failure in our services and infrastructure could also hinder our ability to handle existing or increased traffic on our platform or cause us to lose content stored on our platform, which could significantly harm our business and our ability to retain existing users and attract new users.

As the number of our users increases and our users generate more content on our platform, we may be required to expand and adapt our technology and infrastructure to continue to reliably store and analyze this content. It may become increasingly difficult to maintain and improve the performance of our services, especially during peak usage times, as our services become more complex and our user traffic increases. If our users are unable to access Momo mobile application in a timely fashion, or at all, our user experience may be compromised and the users may seek other mobile social networking tools to meet their needs, and may not return to Momo or use Momo as often in the future, or at all. This would negatively impact our ability to attract users and maintain the level of user engagement.

Existing or future strategic alliances, long-term investments and acquisitions may have a material and adverse effect on our business, reputation and results of operations.

We have made and intend to continue to make long-term investments in third-party companies. From time to time we evaluate and enter into discussions regarding potential long-term investments. Our existing and any future long-term investments could have a material impact on our financial condition and results of operations. If our long-term investments are unable to implement or remediate the necessary controls, procedures and policies, do not perform as we have expected or become less valuable to our business due to a change in our overall business strategy or other reasons, we may not be able to realize the anticipated benefits of investments and we may have to incur unanticipated liabilities, expenses, impairment charges or write-offs.

We may also in the future enter into strategic alliances with various third parties. Strategic alliances with third parties could subject us to a number of risks, including risks associated with sharing proprietary information, non-performance by a counterparty and an increase in expenses incurred in establishing new strategic alliances, any of which may materially and adversely affect our business. We may have little ability to control or monitor their actions and to the extent strategic third parties suffer negative publicity or harm to their reputation from events relating to their business, we may also suffer negative publicity or harm to our reputation by virtue of our association with such third parties.

In addition, we may acquire additional assets, technologies or businesses that are complementary to our existing business. Future acquisitions and the subsequent integration of new assets and businesses into our own would require significant attention from our management and could result in a diversion of resources from our existing business, which in turn could have an adverse effect on our business operations. Acquired assets or businesses may not generate the financial or operating results we expect. Moreover, the costs of identifying and consummating acquisitions may be significant. In addition to possible shareholders’ approval, we may also have to obtain approvals and licenses from the governmental authorities in the PRC for the acquisitions and comply with applicable PRC laws and regulations, which could result in increased costs and delays. Acquisitions could result in the use of substantial amounts of cash, potentially dilutive issuances of equity securities, the incurrence of debt, the incurrence of significant goodwill impairment charges, amortization expenses for other intangible assets and exposure to potential unknown liabilities of the acquired business. Such use of cash may add significant liquidity pressure on us by materially reducing our existing cash balance and adversely affecting our working capital. The sale of equity or equity linked securities may further dilute our existing shareholders. Debt financings may subject us to restrictive covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends.

16

In February 2018, we reached a definitive agreement with Tantan Limited, or Tantan, a social and dating app in China, and all of its shareholders, pursuant to which we agreed to acquire 100% fully diluted equity stake in Tantan for a combination of share consideration and cash. The acquisition of Tantan, which closed in May 2018, exposes us to potential uncertainties and risks. For our acquisition of Tantan, we paid a combination of share consideration and cash, including approximately 5.3 million newly issued Class A ordinary shares of us and US$613.2 million in cash. As Tantan was founded in 2014 and has a short operating track record, it would be difficult for us to assess its future prospect or forecast its future results and thus we may not be able to achieve the objective of our acquisition of Tantan if Tantan’s business does not develop as we expect. In addition, if Tantan continues to incur losses in the future, we would have to consolidate its losses as its sole shareholder, the occurrence of which would adversely affect our future profitability. After the consummation of the acquisition, we may face difficulties in integrating the internal control and financial reporting of Tantan and may incur unanticipated costs and expenses relating to such integration.

We rely on assumptions and estimates to calculate certain key operating metrics, and real or perceived inaccuracies in such metrics may harm our reputation and negatively affect our business.

The respective number of monthly active users of Momo and Tantan is calculated using internal company data that has not been independently verified. While the number of monthly active users is based on what we believe to be reasonable calculations for the applicable periods of measurement, there are inherent challenges in measuring usage and user engagement across our large user base. We treat each account as a separate user for the purposes of calculating our monthly active users, because it may not always be possible to identify people that have set up more than one account. Accordingly, the calculations of our monthly active users may not accurately reflect the actual number of people using Momo and Tantan.

Our measures of user growth and user engagement may differ from estimates published by third parties or from similarly titled metrics used by our competitors due to differences in methodology. If customers or platform partners do not perceive our user metrics to be accurate representations of our user base or user engagement, or if we discover material inaccuracies in our user metrics, our reputation may be harmed and customers and platform partners may be less willing to allocate their resources or spending to Momo or Tantan, which could negatively affect our business and operating results.

We have granted, and expect to continue to grant, share options under our share incentive plans, which may result in increased share-based compensation expenses.

We have adopted three share incentive plans as of the date of this annual report for the purpose of granting share-based compensation awards to employees, directors and consultants to incentivize their performance and align their interests with ours. In November 2012, we adopted a share incentive plan, or the 2012 Plan, which was amended and restated in October 2013. In November 2014, we adopted the 2014 share incentive plan, or the 2014 Plan, pursuant to which a maximum aggregate of 14,031,194 Class A ordinary shares may be issued pursuant to all awards granted thereunder. Beginning in 2017, the number of shares reserved for future issuances under the 2014 Plan will be increased by a number equal to 1.5% of the total number of outstanding shares on the last day of the immediately preceding calendar year, or such lesser number of Class A ordinary shares as determined by our board of directors on the first day of each calendar year during the term of the 2014 Plan. With the adoption of the 2014 Plan, we will no longer grant any incentive shares under the 2012 Plan. In addition, in January 2015, Momo Technology Overseas Holding Company Limited, or Momo BVI, our wholly-owned BVI subsidiary, adopted a share incentive plan, or the BVI Plan. In March 2015, Tantan adopted the 2015 Share Incentive Plan, or the Tantan 2015 Plan, and in July 2018, Tantan adopted the 2018 Share Incentive Plan, or the Tantan 2018 Plan. With the adoption of the Tantan 2018 Plan, we will no longer grant any incentive awards under the Tantan 2015 Plan. As of March 31, 2019, options to purchase 28,769,414 Class A ordinary shares (excluding those already forfeited) had been granted under the 2012 Plan, 5,466,618 of which remained outstanding. In addition, as of March 31, 2019, options to purchase 23,462,705 Class A ordinary shares (excluding those already forfeited and cancelled) and 440,001 restricted share units had been granted under the 2014 Plan, of which 15,404,425 options remained outstanding and 187,500 restricted share units remained outstanding. As of March 31, 2019, options to purchase an aggregate of nil shares of Momo BVI under the BVI Plan remained outstanding. As of March 31, 2019, there were 22,046,890 ordinary shares of Tantan outstanding, and options to purchase 1,308,541 ordinary shares of Tantan (excluding those that have been forfeited) had been granted under the Tantan 2015 Plan, all of which remained outstanding, and options to purchase 4,160,240 ordinary shares of Tantan (excluding those that have been forfeited) had been granted under the Tantan 2018 Plan, all of which remained outstanding. See “Item 6. Directors, Senior Management and Employees—B. Compensation” for a detailed discussion. We expect to incur share-based compensation expenses of RMB749.3 million, RMB683.2 million and RMB715.5 million in 2019 and 2020, and after 2020, respectively, in connection with the currently outstanding share-based awards, and we may grant additional share-based awards under our share incentive plans, which will further increase our share-based compensation expenses. We believe the granting of share-based awards is of significant importance to our ability to attract and retain our employees, and we will continue to grant share-based awards to employees in the future. As a result, our expenses associated with share-based compensation may increase, which may have an adverse effect on our results of operations.

17

If we fail to implement and maintain an effective system of internal controls, we may be unable to accurately report our results of operations or prevent fraud or fail to meet our reporting obligations, and investor confidence and the market price of our ADSs may be materially and adversely affected.

We are subject to reporting obligations under the U.S. securities laws. The Securities and Exchange Commission, or the SEC, as required by Section 404 of the Sarbanes-Oxley Act of 2002, has adopted rules requiring every public company to include a report of management in its annual report that contains management’s assessment of the effectiveness of such company’s internal controls over financial reporting. In addition, an independent registered public accounting firm must attest to and report on the effectiveness of the company’s internal control over financial reporting.

Our management has concluded that our internal controls over financial reporting were effective as of December 31, 2018. Our independent registered public accounting firm has issued an attestation report, which has concluded that our internal control over financial reporting was effective in all material aspects as of December 31, 2018. However, if we fail to maintain effective internal controls over financial reporting in the future, our management and our independent registered public accounting firm may not be able to conclude that we have effective internal controls over financial reporting at a reasonable assurance level. This could result in a loss of investor confidence in the reliability of our financial conditions which in turn could negatively impact the trading price of our ADSs and result in lawsuits being filed against us by our shareholders or otherwise harm our reputation. Furthermore, we have incurred and anticipate that we will continue to incur considerable costs and use significant management time and other resources in an effort to comply with Section 404 and other requirements of the Sarbanes-Oxley Act.

We have limited insurance coverage.

The insurance industry in China is still at an early stage of development and business and litigation insurance products offered in China are limited. Other than the directors and officers liability insurance, we do not maintain any third-party liability, property, business interruption or key-man life insurance. The costs of insuring for these risks and the difficulties associated with acquiring such insurance on commercially reasonable terms make it impractical for us to have such insurance. In addition, any insurance policies that we maintain may not adequately cover our actual loss and we may not be able to successfully claim our losses under the insurance policies at all or on a timely basis. Any business disruption, litigation or natural disaster may cause us to incur substantial costs and divert our resources.

We face risks related to health epidemics and natural disasters.

Our business could be adversely affected by the effects of epidemics. In recent years, there have been outbreaks of epidemics in China and globally. Our business operations could be disrupted if one of our employees is suspected of having H1N1 flu, avian flu or another epidemic, since it could require our employees to be quarantined and/or our offices to be disinfected. In addition, our results of operations could be adversely affected to the extent that the outbreak harms the Chinese economy in general and the mobile internet industry in particular.

We are also vulnerable to natural disasters and other calamities. Although we have servers that are hosted in an offsite location, our backup system does not capture data on a real-time basis and we may be unable to recover certain data in the event of a server failure. We cannot assure you that any backup systems will be adequate to protect us from the effects of fire, floods, typhoons, earthquakes, power loss, telecommunications failures, break-ins, war, riots, terrorist attacks or similar events. Any of the foregoing events may give rise to server interruptions, breakdowns, system failures, technology platform failures or internet failures, which could cause the loss or corruption of data or malfunctions of software or hardware as well as adversely affect our ability to provide services on our platform.

Risks Related to Our Corporate Structure

If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with PRC regulations on foreign investment in internet and other related businesses, or if these regulations or their interpretation change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations.

Current PRC laws and regulations impose certain restrictions or prohibitions on foreign ownership of companies that engage in internet and other related businesses, including the provision of internet content and online game operations. Specifically, foreign ownership of an internet content provider may not exceed 50%. Internet content and online game operations, which are critical to our business, are provided through a number of our PRC incorporated consolidated affiliated entities. Contractual arrangements between us and the consolidated affiliated entities and their respective shareholders allow us to exert effective control over each of these consolidated affiliated entities and enable us to obtain substantially all of the economic benefits arising from these consolidated affiliated entities and consolidate their financial results into our results of operations. Although the structure we have adopted is consistent with the longstanding industry practice and is commonly adopted by comparable companies in China, the PRC government may not agree that these contractual arrangements comply with existing PRC licensing, registration or other regulatory requirements or policies, or requirements or policies that may be adopted in the future.

In the opinion of our PRC counsel, Han Kun Law Offices, the ownership structure of our PRC subsidiaries and consolidated affiliated entities are in compliance with existing PRC laws, rules and regulations. There are, however, substantial uncertainties regarding the interpretation and application of current or future PRC laws and regulations. Thus, we cannot assure you that the PRC government will not ultimately take a view contrary to the opinion of our PRC counsel. If we are found to be in violation of any PRC laws or regulations or if the contractual arrangements among our PRC subsidiaries, our consolidated affiliated entities and their respective shareholders are determined to be illegal or invalid by the PRC court, arbitral tribunal or regulatory authorities, the relevant governmental authorities would have broad discretion in dealing with such violation, including, without limitation:

The imposition of any of these penalties may result in a material and adverse effect on our ability to conduct our business. In addition, if the imposition of any of these penalties causes us to lose the rights to direct the activities of our consolidated affiliated entities and their subsidiaries or the right to receive their economic benefits, we would no longer be able to consolidate our consolidated affiliated entities and their subsidiaries. We do not believe that any penalties imposed or actions taken by the PRC government would result in the liquidation of our company, our PRC subsidiaries, or our consolidated affiliated entities and their subsidiaries.

We rely on contractual arrangements with our consolidated affiliated entities and their respective shareholders for our operations in China, which may not be as effective in providing operational control as direct ownership.

Due to the PRC restrictions or prohibitions on foreign ownership of internet and other related businesses in China, we operate our business in China through a number of our consolidated affiliated entities, in which we have no ownership interest. We rely on a series of contractual arrangements with our consolidated affiliated entities and their respective shareholders, including the powers of attorney, to control and operate its business.

19

Our ability to control the consolidated affiliated entities depends on the powers of attorney, pursuant to which our PRC subsidiaries can vote on all matters requiring shareholder approval in the consolidated affiliated entities. We believe this power of attorney is legally enforceable but may not be as effective as direct equity ownership. These contractual arrangements are intended to provide us with effective control over our consolidated affiliated entities and allow us to obtain economic benefits from them. See “Item 4. Information on the Company—C. Organizational Structure—Contractual Arrangements with Our Consolidated Affiliated Entities and Their Respective Shareholders” for more details about these contractual arrangements.

Although we have been advised by our PRC counsel, Han Kun Law Offices, that these contractual arrangements are valid, binding and enforceable under existing PRC laws and regulations, these contractual arrangements may not be as effective in providing control over our consolidated affiliated entities as direct ownership. If our consolidated affiliated entities or their respective shareholders fail to perform their respective obligations under the contractual arrangements, we may incur substantial costs and expend substantial resources to enforce our rights. All of these contractual arrangements are governed by and interpreted in accordance with PRC law, and disputes arising from these contractual arrangements will be resolved through arbitration in China. However, the legal system in China, particularly as it relates to arbitration proceedings, is not as developed as in other jurisdictions, such as the United States. See “—Risks Related to Doing Business in China—Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.” There are very few precedents and little official guidance as to how contractual arrangements in the context of a variable interest entity, or a consolidated affiliated entity, should be interpreted or enforced under PRC law. There remain significant uncertainties regarding the ultimate outcome of arbitration should legal action become necessary. These uncertainties could limit our ability to enforce these contractual arrangements. In addition, arbitration awards are final and can only be enforced in PRC courts through arbitration award recognition proceedings, which could cause additional expenses and delays. In the event we are unable to enforce these contractual arrangements or we experience significant delays or other obstacles in the process of enforcing these contractual arrangements, we may not be able to exert effective control over our consolidated affiliated entities and may lose control over the assets owned by our consolidated affiliated entities. As a result, we may be unable to consolidate our consolidated affiliated entities in our consolidated financial statements, our ability to conduct our business may be negatively affected, and our business operations could be severely disrupted, which could materially and adversely affect our results of operations and financial condition.

We may lose the ability to use and enjoy assets held by our consolidated affiliated entities that are important to the operation of our business if consolidated affiliated entities declares bankruptcy or becomes subject to a dissolution or liquidation proceeding.

Our consolidated affiliated entities hold certain assets that are important to our business operations, including the value-added telecommunication service license concerning the internet information service, or the ICP license, the internet culture operation license and the internet audio/video program transmission license. Under our contractual arrangements, the respective shareholders of our consolidated affiliated entities may not voluntarily liquidate our consolidated affiliated entities or approve them to sell, transfer, mortgage or dispose of their respective assets or legal or beneficial interests exceeding certain threshold in the business in any manner without our prior consent. However, in the event that the shareholders breach this obligation and voluntarily liquidate our consolidated affiliated entities, or our consolidated affiliated entities declare bankruptcy, or all or part of their assets become subject to liens or rights of third-party creditors, we may be unable to continue some or all of our business operations, which could materially and adversely affect our business, financial condition and results of operations. Furthermore, if our consolidated affiliated entities undergo a voluntary or involuntary liquidation proceeding, their respective shareholders or unrelated third-party creditors may claim rights to some or all of its assets, thereby hindering our ability to operate our business, which could materially and adversely affect our business, financial condition and results of operations.

Contractual arrangements we have entered into with our consolidated affiliated entities may be subject to scrutiny by the PRC tax authorities. A finding that we owe additional taxes could significantly reduce our consolidated net income and the value of your investment.

Pursuant to applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities. We may be subject to adverse tax consequences if the PRC tax authorities determine that the contractual arrangements among our PRC subsidiaries, our consolidated affiliated entities and their respective shareholders are not on an arm’s length basis and therefore constitute favorable transfer pricing. As a result, the PRC tax authorities could require that our consolidated affiliated entities adjust their taxable income upward for PRC tax purposes. Such an adjustment could adversely affect us by increasing our consolidated affiliated entities’ tax expenses without reducing the tax expenses of our PRC subsidiaries, subjecting our consolidated affiliated entities to late payment fees and other penalties for under-payment of taxes, and resulting in our PRC subsidiaries’ loss of their preferential tax treatment. Our consolidated results of operations may be adversely affected if our consolidated affiliated entities’ tax liabilities increase or if it is subject to late payment fees or other penalties.

If the chops of our PRC subsidiaries and our consolidated affiliated entities are not kept safely, are stolen or are used by unauthorized persons or for unauthorized purposes, the corporate governance of these entities could be severely and adversely compromised.

In China, a company chop or seal serves as the legal representation of the company towards third parties even when unaccompanied by a signature. Each legally registered company in China is required to maintain a company chop, which must be registered with the local Public Security Bureau. In addition to this mandatory company chop, companies may have several other chops which can be used for specific purposes. The chops of our PRC subsidiaries and our consolidated affiliated entities are generally held securely by personnel designated or approved by us in accordance with our internal control procedures. To the extent those chops are not kept safe, are stolen or are used by unauthorized persons or for unauthorized purposes, the corporate governance of these entities could be severely and adversely compromised and those corporate entities may be bound to abide by the terms of any documents so chopped, even if they were chopped by an individual who lacked the requisite power and authority to do so.

The shareholders of our consolidated affiliated entities may have potential conflicts of interest with us, which may materially and adversely affect our business.

Some of the shareholders of our consolidated affiliated entities are also our directors or officers. Conflicts of interest may arise between the roles of these individuals as directors or officers of our company and as shareholders of our consolidated affiliated entities. We rely on these individuals to abide by the laws of the Cayman Islands, which provide that directors and officers owe a fiduciary duty to our company to act in good faith and in the best interest of our company and not to use their positions for personal gain. The shareholders of our consolidated affiliated entities have executed powers of attorney to appoint our PRC subsidiaries, or a person designated by our PRC subsidiaries to vote on their behalf and exercise voting rights as shareholders of our consolidated affiliated entities. We cannot assure you that when conflicts arise, shareholders of our consolidated affiliated entities will act in the best interest of our company or that conflicts will be resolved in our favor. If we cannot resolve any conflicts of interest or disputes between us and these shareholders, we would have to rely on legal proceedings, which may be expensive, time-consuming and disruptive to our operations. There is also substantial uncertainty as to the outcome of any such legal proceedings.

We may rely on dividends paid by our PRC subsidiaries to fund cash and financing requirements. Any limitation on the ability of our PRC subsidiaries to pay dividends to us could have a material adverse effect on our ability to conduct our business and to pay dividends to holders of the ADSs and our ordinary shares.

We are a holding company, and we may rely on dividends to be paid by our PRC subsidiaries for our cash and financing requirements, including the funds necessary to pay dividends and other cash distributions to the holders of the ADSs and our ordinary shares and service any debt we may incur. If our PRC subsidiaries incur debt on their own behalf in the future, the instruments governing the debt may restrict their ability to pay dividends or make other distributions to us.

Under PRC laws and regulations, a wholly foreign-owned enterprises in the PRC, such as Beijing Momo Information Technology Co., Ltd., or Beijing Momo IT, may pay dividends only out of its accumulated profits as determined in accordance with PRC accounting standards and regulations. In addition, a wholly foreign-owned enterprise is required to set aside at least 10% of its after-tax profits each year, after making up previous years’ accumulated losses, if any, to fund certain statutory reserve funds, until the aggregate amount of such a fund reaches 50% of its registered capital. At the discretion of the board of director of the wholly foreign-owned enterprise, it may allocate a portion of its after-tax profits based on PRC accounting standards to staff welfare and bonus funds. These reserve funds and staff welfare and bonus funds are not distributable as cash dividends. Any limitation on the ability of our wholly-owned PRC subsidiary to pay dividends or make other distributions to us could materially and adversely limit our ability to grow, make investments or acquisitions that could be beneficial to our business, pay dividends, or otherwise fund and conduct our business.

Risks Related to Doing Business in China

Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.

The PRC legal system is based on written statutes and court decisions have limited precedential value. The PRC legal system evolves rapidly, and the interpretations of many laws, regulations and rules may contain inconsistencies and enforcement of these laws, regulations and rules involves uncertainties.

From time to time, we may have to resort to administrative and court proceedings to enforce our legal rights. However, since PRC judicial and administrative authorities have significant discretion in interpreting and implementing statutory and contractual terms, it may be more difficult to predict the outcome of a judicial or administrative proceeding than in more developed legal systems. Furthermore, the PRC legal system is based, in part, on government policies and internal rules, some of which are not published in a timely manner, or at all, but which may have retroactive effect. As a result, we may not always be aware of any potential violation of these policies and rules. Such unpredictability towards our contractual, property (including intellectual property) and procedural rights could adversely affect our business and impede our ability to continue our operations.

We face uncertainties with respect to the implementation of the Foreign Investment Law and how it may impact the viability of our current corporate structure, corporate governance and business operations.

On March 15, 2019, the National People’s Congress approved the Foreign Investment Law, which will take effect on January 1, 2020 and replace the Sino-Foreign Equity Joint Venture Enterprise Law, the Sino-Foreign Cooperative Joint Venture Enterprise Law and the Foreign Owned Enterprise Law, together with their implementation rules and ancillary regulations, to become the legal foundation for foreign investment in the PRC. The Foreign Investment Law embodies an expected PRC regulatory trend to rationalize its foreign investment regulatory regime in line with prevailing international practice and the legislative efforts to unify the corporate legal requirements for both foreign and domestic investments. Under the Foreign Investment Law, “foreign investment” refers to the investment activities directly or indirectly conducted by foreign individuals, enterprises or other entities in China. The Foreign Investment Law stipulates three forms of foreign investment, and does not explicitly stipulate contractual arrangements as a form of foreign investment. However, the Foreign Investment Law provides a catch-all provision under the definition of “foreign investment” to include investments made by foreign investors in China through means stipulated by laws or administrative regulations, or other methods prescribed by the State Council. Therefore, there are possibilities that future laws, administrative regulations or provisions prescribed by the State Council may regard contractual arrangements as a form of foreign investment, at which time it would be uncertain as to whether foreign investment via contractual arrangements would be deemed to be in violation of the foreign investment access requirements and how the above-mentioned contractual arrangements would be regulated. There is no guarantee that the contractual arrangements and our business will not be materially and adversely affected in the future due to changes in PRC laws and regulations. If future laws, administrative regulations or provisions prescribed by the State Council mandate further actions to be completed by companies with existing contractual arrangements, we may face substantial uncertainties as to whether such actions can be timely completed, or at all. Failure to take timely and appropriate measures to cope with any of these or similar regulatory compliance challenges could materially and adversely affect our current corporate structure and business operations.

If we fail to obtain and maintain the requisite licenses and approvals required under the complex regulatory environment applicable to our businesses in China, or if we are required to take compliance actions that are time-consuming or costly, our business, financial condition and results of operations may be materially and adversely affected.

The internet and mobile industries in China are highly regulated. Beijing Momo Technology Co., Ltd., or Beijing Momo, and its subsidiaries are required to obtain and maintain applicable licenses and approvals from different regulatory authorities in order to provide their current services. Under the current PRC regulatory scheme, a number of regulatory agencies, including but not limited to the State Administration of Press, Publication, Radio, Film and Television, or SARFT, the Ministry of Culture, or MOC, Ministry of Industry and Information Technology, or MIIT, and the State Council Information Office, or SCIO, jointly regulate all major aspects of the internet industry, including the mobile internet and mobile games businesses. Operators must obtain various government approvals and licenses for relevant mobile business.

22

We have obtained the ICP licenses for provision of internet information services, internet culture operation license for operation of online games, and internet audio/video program transmission license for our live video service. These licenses are essential to the operation of our business and are generally subject to regular government review or renewal. However, we cannot assure you that we can successfully renew these licenses in a timely manner or that these licenses are sufficient to conduct all of our present or future business. In addition, we cannot assure you that we will be able to secure any additional licenses that we may need to conduct our operations.

We are also required to obtain an internet publishing license from SARFT in order to publish online games through the mobile networks. As of the date of this annual report, we have yet to obtain an internet publishing license, and are in the process of preparing the application documents. We have entered into several cooperation agreements with entities holding the internet publishing license in order to publish online games. Each mobile game is also required to be approved by SARFT prior to the commencement of its operations in China. As of the date of this annual report, we have obtained approvals from the SARFT for all of the 12 games. In the event of any failure to meet the above-mentioned requirements, we may no longer be able to offer games on our platform, which would have an adverse effect on our business and results of operations. All domestic online games must be filed with the MOC within 30 days after operation, and all imported online games must be approved by the MOC. As of March 31, 2019, 11 of the 12 online games we offered had completed the filing with the MOC. If we fail to complete, obtain or maintain any of the required licenses or approvals or make the necessary filings, we may be subject to various penalties, such as confiscation of the net revenues that were generated through online games, the imposition of fines and the discontinuation or restriction of our operations of online games.

Failure to complete, obtain or maintain any of the required licenses or approvals or make the necessary filings has resulted in, and may in the future result in, us being subjected to various penalties, such as confiscation of the net revenues that were generated through the unlicensed internet or mobile activities, the imposition of fines and the discontinuation or restriction of our operations. Any such penalties may disrupt our business operations and materially and adversely affect our business, financial condition and results of operations.

Regulation and censorship of information disseminated over the mobile and internet in China may adversely affect our business and subject us to liability for content posted on our platform.

Internet companies in China are subject to a variety of existing and new rules, regulations, policies, and license and permit requirements. In connection with enforcing these rules, regulations, policies and requirements, relevant government authorities may suspend services by, or revoke licenses of, any internet or mobile content service provider that is deemed to provide illicit or pornographic information or content online or on mobile devices, and such activities may be intensified in connection with any ongoing government campaigns to eliminate prohibited content online. The competent government authorities, including the State Internet Information Office, the Ministry of Industry and Information Technology and the Ministry of Public Security, may crack down on illicit and pornographic information and content in the internet information services industry from time to time. Applicable sanctions, including fines, revocation of online publishing and online video licenses, and criminal prosecution, may be imposed on the provider of such information or content or its responsible officers.

We endeavor to eliminate illicit and pornographic information and content from our platform. We have made substantial investments in resources to monitor content that users post on our platform and the way in which our users engage with each other through our platform. Since our inception, we have terminated tens of million user accounts because we viewed content generated by those users to be indecent and we terminated a substantial percentage of new user accounts in order to eliminate spam, fictitious accounts and indecent content from our platform. We use a variety of methods to ensure our platform remains a healthy and positive experience for our users, including a designated content management team, licensed third-party software, and our own data analytics software. Although we employ these methods to filter our users and content posted by our users, we cannot be sure that our internal content control efforts will be sufficient to remove all content that may be viewed as indecent or otherwise non-compliant with PRC law and regulations. Government standards and interpretations as to what constitutes illicit and pornographic online information, content or behavior are subject to interpretation and may change. Government standards and interpretations may change in a manner that could render our current monitoring efforts insufficient. The Chinese government has wide discretion in regulating online activities and, irrespective of our efforts to control the content on our platform, government campaigns and other actions to reduce illicit and pornographic content and activities could subject us to negative press or regulatory challenges and sanctions, including fines, the suspension or revocation of our licenses to operate in China or a ban of our platform, including closure of one or more parts of or our entire business. Further, our senior management could be held criminally liable if we are deemed to be profiting from illicit and pornographic content on our platform. Although our business and operations have not been materially adversely affected by government campaigns or any other regulatory actions in the past, we cannot assure you that our business and operations will be immune from government actions or sanctions in the future. If government actions or sanctions are brought against us, or if there are widespread rumors that government actions or sanctions have been brought against us, our reputation could be harmed, we may lose users, customers or platform partners, our revenues and results of operation may be materially and adversely affected and the price of our ADSs could be dramatically reduced.

23

Adverse changes in economic and political policies of the PRC government could have a material and adverse effect on overall economic growth in China, which could materially and adversely affect our business.

Our revenues are substantially generated in China. Accordingly, our results of operations, financial condition and prospects are influenced by economic, political and legal developments in China. Economic reforms begun in the late 1970s have resulted in significant economic growth. However, any economic reform policies or measures in China may from time to time be modified or revised. China’s economy differs from the economies of most developed countries in many respects, including with respect to the amount of government involvement, level of development, growth rate, control of foreign exchange and allocation of resources. While the PRC economy has experienced significant growth in the past 30 years, growth has been uneven across different regions and between economic sectors. The PRC government exercises significant control over China’s economic growth through strategically allocating resources, controlling the payment of foreign currency-denominated obligations, setting monetary policy and providing preferential treatment to particular industries or companies. Although the Chinese economy has grown significantly in the past decade, that growth may not continue, as evidenced by the slowing of the growth of the Chinese economy since 2012. Any adverse changes in economic conditions in China, in the policies of the Chinese government or in the laws and regulations in China could have a material adverse effect on the overall economic growth of China. Such developments could adversely affect our business and operating results, lead to reduction in demand for our services and adversely affect our competitive position.

Under the PRC Enterprise Income Tax Law, we may be classified as a PRC “resident enterprise,” which could result in unfavorable tax consequences to us and our shareholders and have a material adverse effect on our results of operations and the value of your investment.

Under the PRC Enterprise Income Tax Law, or the EIT Law, which became effective on January 1, 2008, as amended on September 1, 2011, February 24, 2017 and further amended on December 29, 2018, an enterprise established outside the PRC with “de facto management bodies” within the PRC is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. In 2009, the State Administration of Taxation, or the SAT, issued the Notice Regarding the Determination of Chinese-Controlled Overseas Incorporated Enterprises as PRC Tax Resident Enterprise on the Basis of De Facto Management Bodies, or SAT Circular 82, which provides certain specific criteria for determining whether the “de facto management body” of a PRC-controlled enterprise that is incorporated offshore is located in China. Further to SAT Circular 82, on July 27, 2011, the SAT issued the Administrative Measures for Enterprise Income Tax of Chinese-Controlled Offshore Incorporated Resident Enterprises (Trial), or SAT Bulletin 45, to provide more guidance on the implementation of SAT Circular 82; the bulletin became effective on September 1, 2011. SAT Bulletin 45 clarified certain issues in the areas of resident status determination, post-determination administration and competent tax authorities’ procedures.

According to SAT Circular 82, an offshore incorporated enterprise controlled by a PRC enterprise or a PRC enterprise group will be considered as a PRC tax resident enterprise by virtue of having its “de facto management body” in China and will be subject to PRC enterprise income tax on its worldwide income only if all of the following conditions are met: (a) the senior management and core management departments in charge of its daily operations function have their presence mainly in the PRC; (b) its financial and human resources decisions are subject to determination or approval by persons or bodies in the PRC; (c) its major assets, accounting books, company seals, and minutes and files of its board and shareholders’ meetings are located or kept in the PRC; and (d) more than half of the enterprise’s directors or senior management with voting rights habitually reside in the PRC. SAT Bulletin 45 specifies that when provided with a copy of Chinese tax resident determination certificate from a resident Chinese controlled offshore incorporated enterprise, the payer should not withhold 10% income tax when paying the Chinese-sourced dividends, interest, royalties, among others, to the Chinese controlled offshore incorporated enterprise.

24

Although SAT Circular 82 and SAT Bulletin 45 only apply to offshore incorporated enterprises controlled by PRC enterprises or PRC enterprise groups and not those controlled by PRC individuals or foreigners, the determination criteria set forth therein may reflect the SAT’s general position on how the term “de facto management body” could be applied in determining the tax resident status of offshore enterprises, regardless of whether they are controlled by PRC enterprises, individuals or foreigners.

If the PRC tax authorities determine that we or any of our non-PRC subsidiaries is a PRC resident enterprise for PRC enterprise income tax purposes, then we or any such non-PRC subsidiary could be subject to PRC tax at a rate of 25% on its world-wide income, which could materially reduce our net income. In addition, we will also be subject to PRC enterprise income tax reporting obligations.

If the PRC tax authorities determine that our company is a PRC resident enterprise for PRC enterprise income tax purposes, gains realized on the sale or other disposition of ADSs or ordinary shares may be subject to PRC tax, at a rate of 10% in the case of non-PRC enterprise holders or 20% in the case of non-PRC individual holders, if such gains are deemed to be from PRC sources. In addition, any payments of dividends or interest on the ADSs, ordinary shares may be subject to PRC withholding tax at a rate of 10% in the case of non-PRC enterprise holders or 20% in the case of non-PRC individual holders, if such dividends or interest payments are deemed to be from PRC sources. Any PRC tax liability may be reduced under applicable tax treaties. However, it is unclear whether if we are considered a PRC resident enterprise, holders of our ADSs, ordinary shares will be able to claim the benefit of income tax treaties between China and other countries.

Further, if we are required to withhold PRC tax from interest payments on the ADSs, we may be required, subject to certain exceptions, to pay additional amounts as will result in receipt by holders of ADSs of such amounts as would have been received had no such withholding been required. The requirement to pay additional amounts will increase the cost of servicing interest payments on the ADSs and could have an adverse effect on our financial condition.

We face uncertainty with respect to indirect transfer of equity interests in PRC resident enterprises by their non-PRC holding companies.

We face uncertainties regarding the reporting on and consequences of previous private equity financing transactions involving the transfer and exchange of shares in our company by non-resident investors. According to the Notice on Strengthening Administration of Enterprise Income Tax for Share Transfers by Non-PRC Resident Enterprises issued by the PRC State Administration of Taxation on December 10, 2009, with retroactive effect from January 1, 2008, or SAT Circular 698, where a non-resident enterprise transfers the equity interests in a PRC resident enterprise indirectly through a disposition of equity interests in an overseas holding company (other than a purchase and sale of shares issued by a PRC resident enterprise in public securities market), or an Indirect Transfer, and such overseas holding company is located in a tax jurisdiction that: (a) has an effective tax rate less than 12.5% or (b) does not tax foreign income of its residents, the non-resident enterprise, as the seller, shall report such Indirect Transfer to the competent tax authority of the PRC resident enterprise within 30 days of execution of the equity transfer agreement for such Indirect Transfer. The PRC tax authority will examine the true nature of the Indirect Transfer, and if the tax authority considers that the foreign investor has adopted an abusive arrangement without reasonable commercial purposes and for the purpose of avoiding or reducing PRC tax, they will disregard the existence of the overseas holding company that is used for tax planning purposes and re-characterize the Indirect Transfer. As a result, gains derived from such Indirect Transfer may be subject to PRC withholding tax at the rate of up to 10%. SAT Circular 698 also points out that when a non-resident enterprise transfers its equity interests in a PRC resident enterprise to its related parties at a price lower than the fair market value, the competent tax authorities have the power to make a reasonable adjustment on the taxable income of the transaction.

On February 3, 2015, the SAT issued a Public Notice 2015 No. 7, or Public Notice 7, to supersede existing provisions in relation to the Indirect Transfer as set forth in Circular 698, while the other provisions of Circular 698 remain in force. Public Notice 7 introduces a new tax regime that is significantly different from that under Circular 698. Public Notice extends its tax jurisdiction to capture not only Indirect Transfer as set forth under Circular 698 but also transactions involving transfer of immovable property in China and assets held under the establishment and place in China of a foreign company through the offshore transfer of a foreign intermediate holding company. Public Notice 7 also addresses the transfer of the equity interest in a foreign intermediate holding company widely. In addition, Public Notice 7 provides clearer criteria than Circular 698 on how to assess reasonable commercial purposes and introduces safe harbor scenarios applicable to internal group restructurings. However, it also brings challenges to both the foreign transferor and transferee (or other person who is obligated to pay for the transfer) of the Indirect Transfer as they have to make self-assessment on whether the transaction should be subject to PRC tax and to file or withhold the PRC tax accordingly. In October 2017, the SAT issued the Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or Bulletin 37, which came into effect on December 1, 2017. The Bulletin 37 replaced and superseded, among other circulars, Circular 698, and further clarifies the practice and procedures of the withholding of non-resident enterprise income tax. Where a non-resident enterprise transfers taxable assets indirectly by disposing of the equity interests of an overseas holding company, which constitutes an Indirect Transfer, the non-resident enterprise as either the transferor or the transferee, or the PRC entity that directly owns the taxable assets, may report such Indirect Transfer to the relevant tax authority.

25

Where non-resident investors were involved in our private equity financing, if such transactions were determined by the tax authorities to lack reasonable commercial purpose, we and our non-resident investors may become at risk of being taxed under Bulletin 37 and Public Notice 7 and may be required to expend valuable resources to comply with Bulletin 37 and Public Notice 7 or to establish that we should not be taxed under Bulletin 37 and Public Notice 7, which may have a material adverse effect on our financial condition and results of operations or the non-resident investors’ investments in us.

The PRC tax authorities have the discretion under SAT Circular 59, Bulletin 37 and Public Notice 7 to make adjustments to the taxable capital gains based on the difference between the fair value of the equity interests transferred and the cost of investment. We may pursue acquisitions in the future that may involve complex corporate structures. If we are considered a non-resident enterprise under the PRC Enterprise Income Tax Law and if the PRC tax authorities make adjustments to the taxable income of the transactions under SAT Circular 59, Bulletin 37 and Public Notice 7, our income tax costs associated with such potential acquisitions will be increased, which may have an adverse effect on our financial condition and results of operations.

China’s M&A Rules and certain other PRC regulations establish complex procedures for some acquisitions of Chinese companies by foreign investors, which could make it more difficult for us to pursue growth through acquisitions in China.

The Regulations on Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rules, and other recently adopted regulations and rules concerning mergers and acquisitions established additional procedures and requirements that could make merger and acquisition activities by foreign investors more time consuming and complex. For example, the M&A Rules require that MOFCOM be notified in advance of any change-of-control transaction in which a foreign investor takes control of a PRC domestic enterprise, if (i) any important industry is concerned, (ii) such transaction involves factors that impact or may impact national economic security, or (iii) such transaction will lead to a change in control of a domestic enterprise which holds a famous trademark or PRC time-honored brand. Moreover, the Anti-Monopoly Law promulgated by the Standing Committee of the National People’s Congress on August 30, 2007 and effective as of August 1, 2008 requires that transactions which are deemed concentrations and involve parties with specified turnover thresholds (i.e., during the previous fiscal year, (i) the total global turnover of all operators participating in the transaction exceeds RMB10 billion and at least two of these operators each had a turnover of more than RMB400 million within China, or (ii) the total turnover within China of all the operators participating in the concentration exceeded RMB2 billion, and at least two of these operators each had a turnover of more than RMB400 million within China) must be cleared by MOFCOM before they can be completed. In addition, on February 3, 2011, the General Office of the State Council promulgated a Notice on Establishing the Security Review System for Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the Circular 6, which officially established a security review system for mergers and acquisitions of domestic enterprises by foreign investors. Further, on August 25, 2011, MOFCOM promulgated the Regulations on Implementation of Security Review System for the Merger and Acquisition of Domestic Enterprises by Foreign Investors, or the MOFCOM Security Review Regulations, which became effective on September 1, 2011, to implement the Circular 6. Under Circular 6, a security review is required for mergers and acquisitions by foreign investors having “national defense and security” concerns and mergers and acquisitions by which foreign investors may acquire the “de facto control” of domestic enterprises with “national security” concerns. Under the MOFCOM Security Review Regulations, MOFCOM will focus on the substance and actual impact of the transaction when deciding whether a specific merger or acquisition is subject to security review. If MOFCOM decides that a specific merger or acquisition is subject to security review, it will submit it to the Inter-Ministerial Panel, an authority established under the Circular 6 led by the National Development and Reform Commission, or NDRC, and MOFCOM under the leadership of the State Council, to carry out security review. The regulations prohibit foreign investors from bypassing the security review by structuring transactions through trusts, indirect investments, leases, loans, control through contractual arrangements or offshore transactions. There is no explicit provision or official interpretation stating that the merging or acquisition of a company engaged in the mobile games business requires security review, and there is no requirement that acquisitions completed prior to the promulgation of the Security Review Circular are subject to MOFCOM review.

26

In the future, we may grow our business by acquiring complementary businesses. Complying with the requirements of the above-mentioned regulations and other relevant rules to complete such transactions could be time consuming, and any required approval processes, including obtaining approval from the MOFCOM or its local counterparts may delay or inhibit our ability to complete such transactions. It is unclear whether our business would be deemed to fall into the industry that raises “national defense and security” or “national security” concerns. However, MOFCOM or other government agencies may publish explanations in the future determining that our business is in an industry subject to the security review, in which case our future acquisitions in the PRC, including those by way of entering into contractual control arrangements with target entities, may be closely scrutinized or prohibited.

PRC regulations relating to offshore investment activities by PRC residents may limit our PRC subsidiary’s ability to increase its registered capital or distribute profits to us or otherwise expose us to liability and penalties under PRC law.

The SAFE promulgated the Circular on Relevant Issues Relating to Domestic Resident’s Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or SAFE Circular 37, in July 2014 that requires PRC residents or entities to register with SAFE or its local branch in connection with their establishment or control of an offshore entity established for the purpose of overseas investment or financing. In addition, such PRC residents or entities must update their SAFE registrations when the offshore special purpose vehicle undergoes material events relating to any change of basic information (including change of such PRC citizens or residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. SAFE Circular 37 has been issued to replace the Notice on Relevant Issues Concerning Foreign Exchange Administration for PRC Residents Engaging in Financing and Roundtrip Investments via Overseas Special Purpose Vehicles, or SAFE Circular 75.

If our shareholders who are PRC residents or entities do not complete their registration with the local SAFE branches, our PRC subsidiary may be prohibited from distributing its profits and proceeds from any reduction in capital, share transfer or liquidation to us, and we may be restricted in our ability to contribute additional capital to our PRC subsidiary. Moreover, failure to comply with the SAFE registration described above could result in liability under PRC laws for evasion of applicable foreign exchange restrictions.

To our knowledge, Messrs. Yan Tang, Yong Li, Zhiwei Li and Xiaoliang Lei have completed SAFE registration in connection with our financings and share transfer. However, we cannot compel all of our beneficial owners to comply with SAFE registration requirements. As a result, we cannot assure you that all of our shareholders or beneficial owners who are PRC residents or entities have complied with, and will in the future make or obtain any applicable registrations or approvals required by, SAFE regulations. Failure by such shareholders or beneficial owners to comply with SAFE regulations, or failure by us to amend the foreign exchange registrations of our PRC subsidiary, could subject us to fines or legal sanctions, restrict our overseas or cross-border investment activities, limit our subsidiaries’ ability to make distributions or pay dividends or affect our ownership structure, which could adversely affect our business and prospects.

Failure to comply with PRC regulations regarding the registration requirements for employee stock ownership plans or share option plans may subject the PRC plan participants or us to fines and other legal or administrative sanctions.

In February 2012, SAFE promulgated the Notices on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plans of Overseas Publicly-Listed Companies, or Circular 7, which replaced the Application Procedures of Foreign Exchange Administration for Domestic Individuals Participating in Employee Stock Ownership Plans or Stock Option Plans of Overseas Publicly-Listed Companies issued by SAFE on March 28, 2007. Under the Circular 7 and other relevant rules and regulations, PRC residents who participate in stock incentive plan in an overseas publicly-listed company are required to register with SAFE or its local branches and complete certain other procedures. Participants of a stock incentive plan who are PRC residents must retain a qualified PRC agent, which could be a PRC subsidiary of such overseas publicly listed company or another qualified institution selected by such PRC subsidiary, to conduct the SAFE registration and other procedures with respect to the stock incentive plan on behalf of its participants. Such participants must also retain an overseas entrusted institution to handle matters in connection with their exercise of stock options, the purchase and sale of corresponding stocks or interests and fund transfers. In addition, the PRC agent is required to amend the SAFE registration with respect to the stock incentive plan if there is any material change to the stock incentive plan, the PRC agent or the overseas entrusted institution or other material changes. We and our PRC employees who have been granted stock options are subject to these regulations. Failure of our PRC stock option holders to complete their SAFE registrations may subject these PRC residents to fines and legal sanctions and may also limit our ability to contribute additional capital into our PRC subsidiary, limit our PRC subsidiary’s ability to distribute dividends to us, or otherwise materially adversely affect our business.

PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversion may restrict or prevent us from using offshore funds to make loans to our PRC subsidiary and consolidated affiliated entity and its subsidiaries, or to make additional capital contributions to our PRC subsidiary.

We are an offshore holding company conducting our operations in China through our PRC subsidiary and consolidated affiliated entity and its subsidiaries. We may make loans to our PRC subsidiary and consolidated affiliated entity and its subsidiaries, or we may make additional capital contributions to our PRC subsidiary, or we may establish new PRC subsidiaries and make capital contributions to these new PRC subsidiaries, or we may acquire offshore entities with business operations in China in an offshore transaction.

Most of these ways are subject to PRC regulations and approvals. For example, loans by us to our wholly-owned PRC subsidiary to finance their activities cannot exceed statutory limits and must be registered with the local counterpart of SAFE. If we decide to finance our wholly-owned PRC subsidiaries by means of capital contributions, these capital contributions must be filed with the MOFCOM or its local counterpart. Due to the restrictions imposed on loans in foreign currencies extended to any PRC domestic companies, we are not likely to make such loans to Beijing Momo, which is PRC domestic company. Further, we are not likely to finance the activities of Beijing Momo by means of capital contributions due to regulatory restrictions relating to foreign investment in PRC domestic enterprises engaged in mobile internet services, online games and related businesses.

On August 29, 2008, SAFE promulgated the Circular on the Relevant Operating Issues Concerning the Improvement of the Administration of the Payment and Settlement of Foreign Currency Capital of Foreign-Invested Enterprises, or SAFE Circular 142, regulating the conversion by a foreign-invested enterprise of foreign currency registered capital into Renminbi by restricting how the converted Renminbi may be used. SAFE Circular 142 provides that Renminbi capital converted from foreign currency registered capital of a foreign-invested enterprise may only be used for purposes within the business scope approved by the applicable governmental authority and may not be used for equity investments within the PRC. In addition, SAFE strengthened its oversight of the flow and use of the Renminbi capital converted from the foreign currency registered capital of a foreign-invested company. The use of such Renminbi capital may not be altered without SAFE approval, and such Renminbi capital may not in any case be used to repay Renminbi loans if the proceeds of such loans have not been used. Violations of SAFE Circular 142 could result in severe monetary or other penalties. Furthermore, SAFE promulgated a circular on November 9, 2010, known as Circular 59, which tightens the examination of the authenticity of settlement of net proceeds from overseas offerings. SAFE further promulgated the Circular on Further Clarification and Regulation of the Issues Concerning the Administration of Certain Capital Account Foreign Exchange Businesses, or Circular 45, on November 9, 2011, which expressly prohibits foreign-invested enterprises from using registered capital settled in Renminbi converted from foreign currencies to grant loans through entrustment arrangements with a bank, repay inter-company loans or repay bank loans that have been transferred to a third party. Circular 142, Circular 59 and Circular 45 may significantly limit our ability to transfer the net proceeds from our overseas offerings, including our initial public offering consummated in December 2014, to our PRC subsidiary and to convert such proceeds into Renminbi, which may adversely affect our liquidity and our ability to fund and expand our business in the PRC.

On April 8, 2015, SAFE promulgated the Circular on Reforming the Management Approach Regarding the Foreign Exchange Capital Settlement of Foreign-invested Enterprises, or SAFE Circular 19, which upon its effective date as of June 1, 2015, superseded the SAFE Circular 142. Circular 19 provides that, among other things, the foreign-invested company may convert the foreign currency in its capital account into RMB on a “at will” basis and the RMB funds so converted can be used for equity investments provided that equity investment is included in the business scope of such foreign-invested company.

On June 9, 2016, SAFE promulgated the Circular on Reforming and Regulation of Administrative Policy on Settlement of Foreign Exchange of Capital Account, or SAFE Circular 16, which became effective on June 9, 2016. According to SAFE Circular 16, the foreign exchange capital of FIEs, foreign debt and funds raised through offshore listings may be settled on a discretionary basis, and can be settled at banks. The proportion of such discretionary settlement is temporarily determined as 100%. The RMB converted from relevant foreign exchange shall be kept in a designated account, and if a domestic enterprise needs to make further payment from such account, it still must provide supporting documents and go through the review process with the banks.

Fluctuation in exchange rate may have a material adverse effect on the value of your investment.

Substantially all of our revenues and costs are denominated in RMB. The conversion of RMB into foreign currencies, including U.S. dollars, is based on rates set by the People’s Bank of China. In July 2005, the PRC government changed its decades-old policy of pegging the value of the RMB to the U.S. dollar, and the RMB appreciated more than 20% against the U.S. dollar over the following three years. Between July 2008 and June 2010, this appreciation halted and the exchange rate between the RMB and the U.S. dollar remained within a narrow band. Since June 2010, the RMB has fluctuated against the U.S. dollar, at times significantly and unpredictably. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future. On November 30, 2015, the Executive Board of the International Monetary Fund (IMF) completed the regular five-year review of the basket of currencies that make up the Special Drawing Right, or the SDR, and decided that with effect from October 1, 2016, RMB is determined to be a freely usable currency and will be included in the SDR basket as a fifth currency, along with the U.S. dollar, the Euro, the Japanese yen and the British pound. In the fourth quarter of 2016, the RMB has depreciated significantly in the backdrop of a surging U.S. dollar and persistent capital outflows of China. This depreciation halted in 2017, and the RMB appreciated approximately 7% against the U.S. dollar during this one-year period. Since February 2018, the RMB has depreciated significantly, over 8% against the U.S. dollar. With the development of the foreign exchange market and progress towards interest rate liberalization and RMB internationalization, the PRC government may in the future announce further changes to the exchange rate system, and we cannot assure you that the RMB will not appreciate or depreciate significantly in value against the U.S. dollar in the future. It is difficult to predict how market forces or PRC or U.S. government policy may impact the exchange rate between the RMB and the U.S. dollar in the future.

Significant revaluation of the RMB may have a material and adverse effect on your investment. To the extent that we need to convert U.S. dollars into RMB for capital expenditures and working capital and other business purposes, appreciation of the RMB against the U.S. dollar would have an adverse effect on the RMB amount we would receive from the conversion. Conversely, if we decide to convert RMB into U.S. dollars for the purpose of making payments for dividends on our ordinary shares or ADSs, strategic acquisitions or investments or other business purposes, appreciation of the U.S. dollar against the RMB would have a negative effect on the U.S. dollar amount available to us. In addition, a significant depreciation of the RMB against the U.S. dollar may significantly reduce the U.S. dollar equivalent of our earnings, which in turn could adversely affect the price of our ADSs.

Very limited hedging options are available in China to reduce our exposure to exchange rate fluctuations. To date, we have not entered into any hedging transactions in an effort to reduce our exposure to foreign currency exchange risk. While we may decide to enter into hedging transactions in the future, the availability and effectiveness of these hedges may be limited and we may not be able to adequately hedge our exposure or to hedge our exposure at all. In addition, our currency exchange losses may be magnified by PRC exchange control regulations that restrict our ability to convert RMB into foreign currency. As a result, fluctuations in exchange rates may have a material adverse effect on your investment.

Our leased property interests may be defective and our right to lease the properties affected by such defects may be challenged, which could cause significant disruption to our business.

Under PRC laws, all lease agreements are required to be registered with the local housing authorities. We presently lease 26 premises in China, and all the landlords of these premises have completed the registration of their ownership rights and the landlords of two of these premises have completed the registration of our lease with the relevant authority. Failure to complete these required registrations may expose our landlords, lessors and us to potential monetary fines. If these registrations are not obtained in a timely manner or at all, we may be subject to monetary fines or may have to relocate our offices and incur the associated losses.

The audit reports included in this annual report have been prepared by our independent registered public accounting firm whose work may not be inspected fully by the Public Company Accounting Oversight Board and, as such, you may be deprived of the benefits of such inspection.

Our independent registered public accounting firm that issues the audit reports included in our annual reports filed with the U.S. Securities and Exchange Commission, as auditors of companies that are traded publicly in the United States and a firm registered with the Public Company Accounting Oversight Board (United States), or the PCAOB, is required by the laws of the United States to undergo regular inspections by the PCAOB to assess its compliance with the laws of the United States and professional standards.

Because we have substantial operations within the PRC and the PCAOB is currently unable to conduct inspections of the work of our independent registered public accounting firm as it relates to those operations without the approval of the Chinese authorities, our independent registered public accounting firm is not currently inspected fully by the PCAOB. This lack of PCAOB inspections in the PRC prevents the PCAOB from regularly evaluating our independent registered public accounting firm’s audits and its quality control procedures. As a result, investors may be deprived of the benefits of PCAOB inspections.

On May 24, 2013, PCAOB announced that it had entered into a Memorandum of Understanding on Enforcement Cooperation with the China Securities Regulatory Commission, or the CSRC, and the Ministry of Finance which establishes a cooperative framework between the parties for the production and exchange of audit documents relevant to investigations in the United States and China. On inspection, it appears that the PCAOB continues to be in discussions with the Mainland China regulators to permit inspections of audit firms that are registered with PCAOB in relation to the audit of Chinese companies that trade on U.S. exchanges. On December 7, 2018, the SEC and the PCAOB issued a joint statement highlighting continued challenges faced by the U.S. regulators in their oversight of financial statement audits of U.S.-listed companies with significant operations in China. The joint statement reflects a heightened interest in this issue. However, it remains unclear what further actions the SEC and PCAOB will take and its impact on Chinese companies listed in the U.S..

Inspections of other firms that the PCAOB has conducted outside the PRC have identified deficiencies in those firms’ audit procedures and quality control procedures, which may be addressed as part of the inspection process to improve future audit quality.

The inability of the PCAOB to conduct full inspections of auditors in the PRC makes it more difficult to evaluate the effectiveness of our independent registered public accounting firm’s audit procedures or quality control procedures as compared to auditors outside the PRC that are subject to PCAOB inspections. Investors may lose confidence in our reported financial information and procedures and the quality of our financial statements.

If the settlement reached between the SEC and the Big Four PRC-based accounting firms (including the Chinese affiliate of our independent registered public accounting firm), concerning the manner in which the SEC may seek access to audit working papers from audits in China of US-listed companies, is not or cannot be performed in a manner acceptable to authorities in China and the US, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act.

In late 2012, the SEC commenced administrative proceedings under Rule 102(e) of its Rules of Practice and also under the Sarbanes-Oxley Act of 2002 against the mainland Chinese affiliates of the “Big Four” accounting firms (including the mainland Chinese affiliate of our independent registered public accounting firm). A first instance trial of the proceedings in July 2013 in the SEC’s internal administrative court resulted in an adverse judgment against the firms. The administrative law judge proposed penalties on the Chinese accounting firms including a temporary suspension of their right to practice before the SEC, although that proposed penalty did not take effect pending review by the Commissioners of the SEC. On February 6, 2015, before a review by the Commissioner had taken place, the Chinese accounting firms reached a settlement with the SEC whereby the proceedings were stayed. Under the settlement, the SEC accepted that future requests by the SEC for the production of documents would normally be made to the CSRC. The Chinese accounting firms would receive requests matching those under Section 106 of the Sarbanes-Oxley Act of 2002, and would be required to abide by a detailed set of procedures with respect to such requests, which in substance require them to facilitate production via the CSRC. The CSRC for its part initiated a procedure whereby, under its supervision and subject to its approval, requested classes of documents held by the accounting firms could be sanitized of problematic and sensitive content so as to render them capable of being made available by the CSRC to US regulators.

30

Under the terms of the settlement, the underlying proceeding against the four PRC-based accounting firms was deemed dismissed with prejudice at the end of four years starting from the settlement date, which was on February 6, 2019. Despite the final ending of the proceedings, the presumption is that all parties will continue to apply the same procedures: i.e. the SEC will continue to make its requests for the production of documents to the CSRC, and the CSRC will normally process those requests applying the sanitisation procedure. We cannot predict whether, in cases where the CSRC does not authorize production of requested documents to the SEC, the SEC will further challenge the four PRC-based accounting firms’ compliance with U.S. law. If additional challenges are imposed on the Chinese affiliates of the “big four” accounting firms, we could be unable to timely file future financial statements in compliance with the requirements of the Exchange Act.

In the event that the SEC restarts the administrative proceedings, depending upon the final outcome, listed companies in the United States with major PRC operations may find it difficult or impossible to retain auditors in respect of their operations in the PRC, which could result in financial statements being determined to not be in compliance with the requirements of the Exchange Act, including possible delisting. Moreover, any negative news about any such future proceedings against these accounting firms may cause investor uncertainty regarding China-based, United States-listed companies and the market price of our ADSs may be adversely affected.

If the Chinese affiliate of our independent registered public accounting firm were denied, even temporarily, the ability to practice before the SEC and we were unable to timely find another registered public accounting firm to audit and issue an opinion on our financial statements, our financial statements could be determined not to be in compliance with the requirements of the Exchange Act. Such a determination could ultimately lead to the delisting of our ordinary shares from the NYSE or deregistration from the SEC, or both, which would substantially reduce or effectively terminate the trading of our ADSs in the United States.

Risks Related to Our ADSs

The trading price of our ADSs is likely to be volatile, which could result in substantial losses to investors.

The price of our ADSs has been and is likely to continue to be volatile and could fluctuate widely due to factors beyond our control. This may happen because of broad market and industry factors, like the performance and fluctuation of the market prices of other companies with business operations located mainly in China that have listed their securities in the United States. A number of Chinese companies have listed their securities on U.S. stock markets. The securities of some of these companies have experienced significant volatility, including price declines in connection with their initial public offerings. The trading performances of these Chinese companies’ securities after their offerings may affect the attitudes of investors toward Chinese companies listed in the United States in general and consequently may impact the trading performance of our ADSs, regardless of our actual operating performance. Furthermore, the stock market in general has experienced extreme price and volume fluctuations that have often been unrelated or disproportionate to the operating performance of companies like us. These broad market and industry fluctuations may adversely affect the market price of our ADSs. Volatility or a lack of positive performance in our ADS price may also adversely affect our ability to retain key employees, most of whom have been granted options or other equity incentives.

In addition to market and industry factors, the price and trading volume for our ADSs may be highly volatile for factors specific to our own operations, including the following:

31

Any of these factors may result in large and sudden changes in the volume and price at which our ADSs will trade.

In the past, shareholders of public companies have often brought securities class action suits against those companies following periods of instability in the market price of their securities. If we were involved in a class action suit, it could divert a significant amount of our management’s attention and other resources from our business and operations and require us to incur significant expenses to defend the suit, which could harm our results of operations. Any such class action suit, whether or not successful, could harm our reputation and restrict our ability to raise capital in the future. In addition, if a claim is successfully made against us, we may be required to pay significant damages, which could have a material adverse effect on our financial condition and results of operations.

If securities or industry analysts do not publish research or reports about our business, or if they adversely change their recommendations regarding our ADSs, the market price for our ADSs and trading volume could decline.

The trading market for our ADSs will be influenced by research or reports that industry or securities analysts publish about our business. If one or more analysts who cover us downgrade our ADSs, the market price for our ADSs would likely decline. If one or more of these analysts cease to cover us or fail to regularly publish reports on us, we could lose visibility in the financial markets, which in turn could cause the market price or trading volume for our ADSs to decline.

Substantial future sales or the expectation of substantial sales of our ADSs in the public market could cause the price of our ADSs to decline.

Sales of our ADSs in the public market, or the perception that these sales could occur, could cause the market price of our ADSs to decline. Such sales also might make it more difficult for us to sell equity or equity-related securities in the future at a time and price that we deem appropriate. If any existing shareholder or shareholders sell a substantial amount of ADSs, the prevailing market price for our ADSs could be adversely affected. In addition, if we pay for our future acquisitions in whole or in part with additionally issued ordinary shares, your ownership interests in our company would be diluted and this, in turn, could have a material and adverse effect on the price of our ADSs.

Because we may not continue to pay dividends in the foreseeable future, you must rely on price appreciation of our ADSs for return on your investment.

Although we declared special cash dividends to holders of our ordinary shares in March 2019, we may not continue to do so regularly, or at all. Therefore, you may need to rely on price appreciation of our ADSs as the sole source for return on your investment.

Our board of directors has complete discretion as to whether to distribute dividends subject to our memorandum and articles of association and certain restrictions under Cayman Islands law. In addition, our shareholders may by ordinary resolution declare a dividend, but no dividend may exceed the amount recommended by our directors. Even if our board of directors decides to declare and pay dividends, the timing, amount and form of future dividends, if any, will depend on, among other things, our future results of operations and cash flow, our capital requirements and surplus, the amount of distributions, if any, received by us from our subsidiaries, our financial condition, contractual restrictions and other factors deemed relevant by our board of directors. Accordingly, the return on your investment in our ADSs will likely depend entirely upon any future price appreciation of our ADSs. There is no guarantee that our ADSs will appreciate in value or even maintain the price at which you purchased the ADSs. You may not realize a return on your investment in our ADSs and you may even lose your entire investment in our ADSs.

32

Your interests may not always align with those of our shareholders, including our principal shareholder.

You are also reminded that your interests may not always align with those of other shareholders, including our principal shareholders. Mr. Yan Tang, our co-founder, chairman and chief executive officer, has considerable influence over important corporate matters. We have adopted a dual-class voting structure in which our ordinary shares consist of Class A ordinary shares and Class B ordinary shares. Holders of Class A ordinary shares are entitled to one vote per share in respect of matters requiring the votes of shareholders, while holders of Class B ordinary shares are entitled to ten votes per share. Each Class B ordinary share is convertible into one Class A ordinary share at any time by the holder thereof, while Class A ordinary shares are not convertible into Class B ordinary shares under any circumstances. Due to the disparate voting powers associated with our two classes of ordinary shares, Mr. Tang beneficially owned a total of 70.9% of the aggregate voting power of our company as of March 31, 2019. As a result of his majority voting power, Mr. Tang has considerable influence over matters such as electing directors and approving material mergers, acquisitions or other business combination transactions. This concentrated control will limit the ability of holders of our Class A ordinary shares and ADSs to influence corporate matters and could also discourage others from pursuing any potential merger, takeover or other change of control transactions, which could have the effect of depriving the holders of our Class A ordinary shares and our ADSs of the opportunity to sell their shares at a premium over the prevailing market price. We cannot assure you that actions taken by our principal shareholders will completely align with your interests, or that any conflicts of interest will be resolved in a way beneficial to you.

We may be classified as a passive foreign investment company, or PFIC, under U.S. tax law, which could result in adverse U.S. federal income tax consequences to U.S. holders of our ADSs or ordinary shares.

Under United States federal income tax law, we will be classified as a PFIC for any taxable year if either (i) 75% or more of our gross income for the taxable year is “passive” income or (ii) 50% or more of the value of our assets (determined on the basis of a quarterly average) is attributable to assets that produce or are held for the production of passive income (the “asset test”). Although the law in this regard is unclear, we treat Beijing Momo as being owned by us for U.S. federal income tax purposes, not only because we exercise effective control over the operation of this entity but also because we are entitled to substantially all of its economic benefits, and, as a result, we consolidate its results of operations in our consolidated U.S. GAAP financial statements. If it were determined, however, that we are not the owner of Beijing Momo for U.S. federal income tax purposes, we would likely be treated as a PFIC for the taxable year ended December 31, 2018 and would anticipate being a PFIC for future taxable years. Assuming that we are the owner of Beijing Momo for United States federal income tax purposes and based upon our income and assets and the value of our ADSs, we do not believe that we were a PFIC for the taxable year ended December 31, 2018 and do not anticipate becoming a PFIC in the foreseeable future.

However, because PFIC status is a factual determination made annually after the close of each taxable year on the basis of the composition of our income and assets, there can be no assurance that we will not be a PFIC for the current taxable year or any future taxable year. Fluctuations in the market price of our ADSs may cause us to become a PFIC for the current or subsequent taxable years because the value of our assets for purposes of the asset test, including the value of our goodwill and unbooked intangibles, may be determined by reference to the market price of our ADSs from time to time (which may be volatile). In estimating the value of our goodwill and other unbooked intangibles, we have taken into account our current market capitalization. If our market capitalization subsequently declines, we may be or become classified as a PFIC for the current taxable year or future taxable years. In addition, the overall level of our passive assets will be affected by how, and how quickly, we spend our liquid assets. Under circumstances where our revenue from activities that produce passive income significantly increase relative to our revenue from activities that produce non-passive income, or where we determine not to deploy significant amounts of cash for active purposes, our risk of becoming classified as a PFIC may substantially increase. Furthermore, because there are uncertainties in the application of the relevant rules, it is possible that the Internal Revenue Service, or the IRS, may challenge our classification of certain income or assets as non-passive, or our valuation of our goodwill and other unbooked intangibles, each of which may result in our company becoming classified as a PFIC for the current or subsequent taxable years.

If we were to be or become classified as a PFIC, a U.S. Holder (as defined in “Item 10. Additional Information—E. Taxation—United States Federal Income Tax Considerations”) will generally be subject to reporting requirements and may incur significantly increased U.S. federal income tax on gain recognized on the sale or other disposition of the ADSs or ordinary shares and on the receipt of distributions on the ADSs or ordinary shares to the extent such gain or distribution is treated as an “excess distribution” under the U.S. federal income tax rules. Further, if we were a PFIC for any year during which a U.S. Holder held our ADSs or ordinary shares, we generally would continue to be treated as a PFIC for all succeeding years during which such U.S. Holder held our ADSs or ordinary shares. You are urged to consult your tax advisor concerning the U.S. federal income tax consequences of holding and disposing of ADSs or ordinary shares if we are or become classified as a PFIC. For more information see “Item 10. Additional Information—E. Taxation—United States Federal Income Tax Considerations—Passive Foreign Investment Company Rules.”

Our memorandum and articles of association contain anti-takeover provisions that could have a material adverse effect on the rights of holders of our Class A ordinary shares and ADSs.

Our currently effective second amended and restated memorandum and articles of association contain provisions to limit the ability of others to acquire control of our company or cause us to engage in change-of-control transactions. These provisions could have the effect of depriving our shareholders of an opportunity to sell their shares at a premium over prevailing market prices by discouraging third parties from seeking to obtain control of our company in a tender offer or similar transaction. Our dual-class voting structure gives disproportionate voting power to the Class B ordinary shares held by Gallant Future Holdings Limited and New Heritage Global Limited, both of which are wholly owned by a family trust controlled by Yan Tang, our co-founder, chairman and chief executive officer. In addition, our board of directors has the authority, without further action by our shareholders, to issue preferred shares in one or more series and to fix their designations, powers, preferences, privileges, and relative participating, optional or special rights and the qualifications, limitations or restrictions, including dividend rights, conversion rights, voting rights, terms of redemption and liquidation preferences, any or all of which may be greater than the rights associated with our Class A ordinary shares, in the form of ADS or otherwise. Preferred shares could be issued quickly with terms calculated to delay or prevent a change in control of our company or make removal of management more difficult. If our board of directors decides to issue preferred shares, the price of our ADSs may fall and the voting and other rights of the holders of our Class A ordinary shares and ADSs may be materially and adversely affected.

Provisions of our convertible senior notes could discourage an acquisition of us by a third party.

In July 2018, we issued $725 million principal amount of convertible senior notes due 2025. Certain provisions of our convertible senior notes could make it more difficult or more expensive for a third party to acquire us. The indenture for our convertible senior notes define a “fundamental change” to include, among other things: (i) any person or group becoming a direct or indirect beneficial owner of our company’s ordinary share capital (including ordinary share capital held in the form of ADSs) representing more than 50% of the voting power of our ordinary share capital or more than 50% of our outstanding Class A ordinary shares (including Class A ordinary shares held in the form of ADSs); (ii) any recapitalization, reclassification or change of our Class A ordinary shares or ADSs as a result of which these securities would be converted into, or exchanged for, stock, other securities, other property or assets or any share exchange, consolidation or merger of our company pursuant to which our Class A ordinary shares or ADSs will be converted into cash, securities or other property or any sale, lease or other transfer in one transaction or a series of transaction of all or substantially all of our consolidated assets, taken as a whole, to any person other than one of our subsidiaries; (iii) the approval of any plan or proposal for the liquidation or dissolution of our company by our shareholders; (iv) our ADSs ceasing to be listed or quoted on any of The New York Stock Exchange, The NASDAQ Global Select Market or The NASDAQ Global Market (or any of their respective successors); or (v) any change in or amendment to the laws, regulations and rules in the PRC or the official interpretation or official application thereof that prohibits us from operating substantially all of our business operations and prevents us from continuing to derive substantially all of the economic benefits from our business operations. Upon the occurrence of a fundamental change, holders of these notes will have the right, at their option, to require us to repurchase all of their notes or any portion of the principal amount of such notes in principal amounts of US$1,000 or integral multiples thereof. In the event of a fundamental change, we may also be required to issue additional ADSs upon conversion of our convertible notes.

You may face difficulties in protecting your interests, and your ability to protect your rights through U.S. courts may be limited, because we are registered by way of continuation under Cayman Islands law.

We are an exempted company limited by shares registered under the laws of the Cayman Islands. Our corporate affairs are governed by our memorandum and articles of association, the Companies Law (2018 Revision) of the Cayman Islands and the common law of the Cayman Islands. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands as well as from the common law of England, the decisions of whose courts are of persuasive authority, but are not binding, on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws than the United States. Some U.S. states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law than the Cayman Islands. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

34

Shareholders of Cayman Islands exempted companies like us have no general rights under Cayman Islands law to inspect corporate records or to obtain copies of lists of shareholders of these companies. Our directors have discretion under our articles of association to determine whether or not, and under what conditions, our corporate records may be inspected by our shareholders, but are not obliged to make them available to our shareholders. This may make it more difficult for you to obtain the information needed to establish any facts necessary for a shareholder motion or to solicit proxies from other shareholders in connection with a proxy contest.

As a result of all of the above, shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a company incorporated in the United States.

Certain judgments obtained against us by our shareholders may not be enforceable.

We are a Cayman Islands company and most of our assets are located outside of the United States. Substantially all of our current operations are conducted in China. In addition, a majority of our current directors and officers are nationals and residents of countries other than the United States. Most of the assets of these persons are located outside the United States. As a result, it may be difficult or impossible for you to effect service of process within the United States upon us or these persons or to bring an action against us or against these individuals in the United States in the event that you believe that your rights have been infringed under the U.S. federal securities laws or otherwise. Even if you are successful in bringing an action of this kind, the laws of the Cayman Islands and of China may render you unable to enforce a judgment against our assets or the assets of our directors and officers. There is no statutory enforcement in the Cayman Islands of judgments obtained in the federal or state courts of the United States (and the Cayman Islands are not a party to any treaties for the reciprocal enforcement or recognition of such judgments), a judgment obtained in such jurisdiction will be recognized and enforced in the courts of the Cayman Islands at common law, without any re-examination of the merits of the underlying dispute, by an action commenced on the foreign judgment debt in the Grand Court of the Cayman Islands, provided such judgment (a) is given by a foreign court of competent jurisdiction, (b) imposes on the judgment debtor a liability to pay a liquidated sum for which the judgment has been given, (c) is final, (d) is not in respect of taxes, a fine or a penalty, and (e) was not obtained in a manner and is not of a kind the enforcement of which is contrary to natural justice or the public policy of the Cayman Islands. However, the Cayman Islands courts are unlikely to enforce a judgment obtained from the U.S. courts under civil liability provisions of the U.S. federal securities law if such judgment is determined by the courts of the Cayman Islands to give rise to obligations to make payments that are penal or punitive in nature. Because such a determination has not yet been made by a court of the Cayman Islands, it is uncertain whether such civil liability judgments from U.S. courts would be enforceable in the Cayman Islands.

We are a foreign private issuer within the meaning of the rules under the Exchange Act, and as such we are exempt from certain provisions applicable to United States domestic public companies.

Because we are a foreign private issuer under the Exchange Act, we are exempt from certain provisions of the securities rules and regulations in the United States that are applicable to U.S. domestic issuers, including:

35

We are required to file an annual report on Form 20-F within four months of the end of each fiscal year. In addition, we intend to publish our results on a quarterly basis through press releases, distributed pursuant to the rules and regulations of the NASDAQ Global Select Market. Press releases relating to financial results and material events will also be furnished to the SEC on Form 6-K. However, the information we are required to file with or furnish to the SEC will be less extensive and less timely compared to that required to be filed with the SEC by U.S. domestic issuers. As a result, you may not be afforded the same protections or information, which would be made available to you, were you investing in a U.S. domestic issuer. As a Cayman Islands company listed on the NASDAQ Global Select Market, we are subject to the NASDAQ Global Select Market corporate governance listing standards. However, NASDAQ Global Select Market rules permit a foreign private issuer like us to follow the corporate governance practices of its home country. Certain corporate governance practices in the Cayman Islands, which is our home country, may differ significantly from the NASDAQ Global Select Market corporate governance listing standards. To the extent that we choose to utilize the home country exemption for corporate governance matters, our shareholders may be afforded less protection than they otherwise would under the NASDAQ Global Select Market corporate governance listing standards applicable to U.S. domestic issuers. We follow home country practice with respect to annual shareholders meetings and did not hold an annual meeting of shareholders in 2018. As a result, you may not be afforded the same protections or information, which would be made available to you, were you investing in a U.S. domestic issuer.

We are a “controlled company” within the meaning of the Nasdaq Stock Market Rules and, as a result, will and may rely on certain exemptions from certain corporate governance requirements that provide protection to shareholders of other companies.

We are a “controlled company” as defined under the Nasdaq Stock Market Rules because Yan Tang, our co-founder, chairman and chief executive officer, beneficially owns more than 50% of our total voting power. For so long as we remain a controlled company under that definition, we are permitted to elect to rely on certain exemptions from corporate governance rules. We currently rely on an exemption from the rule that a majority of the board of directors must be independent directors. Currently, a majority of the members of our board of directors are not independent directors. As a result, you will not have the same protection afforded to shareholders of companies that are subject to the above-mentioned corporate governance requirement. We may rely on other available exemptions from corporate governance rules in the future.

The voting rights of holders of ADSs are limited by the terms of the deposit agreement, and you may not be able to exercise your right to vote your Class A ordinary shares.

As a holder of our ADSs, you will only be able to exercise the voting rights with respect to the underlying Class A ordinary shares in accordance with the provisions of the deposit agreement. Under the deposit agreement, you must vote by giving voting instructions to the depositary. Upon receipt of your voting instructions, the depositary will vote the underlying Class A ordinary shares in accordance with these instructions. You will not be able to directly exercise your right to vote with respect to the underlying shares unless you register the underlying shares in your own name. Under our currently effective second amended and restated memorandum and articles of association, the minimum notice period required for convening a general meeting is 10 days, exclusive of the day on which notice is given and the day of the meeting. When a general meeting is convened, you may not receive sufficient advance notice to register the shares underlying your ADSs in your own name to allow you to vote with respect to any specific matter. If we ask for your instructions, the depositary will notify you of the upcoming vote and will arrange to deliver our voting materials to you. We cannot assure you that you will receive the voting materials in time to ensure that you can instruct the depositary to vote your shares. In addition, the depositary and its agents are not responsible for failing to carry out voting instructions or for their manner of carrying out your voting instructions. This means that you may not be able to exercise your right to vote and you may have no legal remedy if the shares underlying your ADSs are not voted as you requested.

The depositary for our ADSs will give us a discretionary proxy to vote our Class A ordinary shares underlying your ADSs if you do not instruct the depositary to vote your shares, except in limited circumstances, which could adversely affect your interests.

Under the deposit agreement for the ADSs, if you do not instruct the depositary to vote your shares, the depositary will give us a discretionary proxy to vote our Class A ordinary shares underlying your ADSs at shareholders’ meetings unless:

36

The effect of this discretionary proxy is that if you do not instruct the depositary to vote your shares, you cannot prevent our Class A ordinary shares underlying your ADSs from being voted, except under the circumstances described above. This may make it more difficult for holders of ADSs to influence the management of our company. Holders of our Class A ordinary shares are not subject to this discretionary proxy.

You may not receive dividends or other distributions on our Class A ordinary shares and you may not receive any value for them, if it is illegal or impractical to make them available to you.

The depositary of our ADSs has agreed to pay to you the cash dividends or other distributions it or the custodian receives on Class A ordinary shares or other deposited securities underlying our ADSs, after deducting its fees and expenses. You will receive these distributions in proportion to the number of Class A ordinary shares your ADSs represent. However, the depositary is not responsible if it decides that it is unlawful or impractical to make a distribution available to any holders of ADSs. For example, it would be unlawful to make a distribution to a holder of ADSs if it consists of securities that require registration under the Securities Act but that are not properly registered or distributed under an applicable exemption from registration. The depositary may also determine that it is not feasible to distribute certain property through the mail. Additionally, the value of certain distributions may be less than the cost of mailing them. In these cases, the depositary may determine not to distribute such property. We have no obligation to register under U.S. securities laws any ADSs, ordinary shares, rights or other securities received through such distributions. We also have no obligation to take any other action to permit the distribution of ADSs, ordinary shares, rights or anything else to holders of ADSs. This means that you may not receive distributions we make on our Class A ordinary shares or any value for them if it is illegal or impractical for us to make them available to you. These restrictions may cause a material decline in the value of our ADSs.

You may experience dilution of your holdings due to inability to participate in rights offerings.

We may, from time to time, distribute rights to our shareholders, including rights to acquire securities. Under the deposit agreement, the depositary will not distribute rights to holders of ADSs unless the distribution and sale of rights and the securities to which these rights relate are either exempt from registration under the Securities Act with respect to all holders of ADSs, or are registered under the provisions of the Securities Act. The depositary may, but is not required to, attempt to sell these undistributed rights to third parties, and may allow the rights to lapse. We may be unable to establish an exemption from registration under the Securities Act, and we are under no obligation to file a registration statement with respect to these rights or underlying securities or to endeavor to have a registration statement declared effective. Accordingly, holders of ADSs may be unable to participate in our rights offerings and may experience dilution of their holdings as a result.

You may be subject to limitations on transfer of your ADSs.

Your ADSs are transferable on the books of the depositary. However, the depositary may close its books at any time or from time to time when it deems expedient in connection with the performance of its duties. The depositary may close its books from time to time for a number of reasons, including in connection with corporate events such as a rights offering, during which time the depositary needs to maintain an exact number of ADS holders on its books for a specified period. The depositary may also close its books in emergencies, and on weekends and public holidays. The depositary may refuse to deliver, transfer or register transfers of our ADSs generally when our share register or the books of the depositary are closed, or at any time if we or the depositary thinks it is advisable to do so because of any requirement of law or of any government or governmental body, or under any provision of the deposit agreement, or for any other reason.

We started our operations in July 2011 when our founders established Beijing Momo Technology Co., Ltd., or Beijing Momo, in China. In order to facilitate foreign investment in our company, we incorporated our holding company under the name of Momo Technology Company Limited in the British Virgin Islands in November 2011. In July 2014, Momo Technology Company Limited was redomiciled in the Cayman Islands as an exempted company registered under the laws of the Cayman Islands, and was renamed Momo Inc. The following outlines other major changes to our corporate structure in recent years.

38

In December 2014, we completed our initial public offering and listed our ADSs on the NASDAQ Global Select Market under the symbol “MOMO.”

Our principal executive offices are located at 20th Floor, Block B, Tower 2, Wangjing SOHO, No.1 Futongdong Street, Chaoyang District, Beijing 100102, People’s Republic of China. Our telephone number at this address is +86-10-5731-0567. Our registered office in the Cayman Islands is located at P.O. Box 309, Ugland House, Grand Cayman KY1-1104, Cayman Islands. Our agent for service of process in the United States is Law Debenture Corporate Services Inc., 801 2^nd Avenue, Suite 403, New York, NY 10017.

We operate Momo, one of China’s leading mobile-based social and entertainment platforms. We enable users to discover new relationships, expand their social connections and build meaningful interactions. We connect people and facilitate interactions based on location, interests and a variety of recreational activities including live talent shows, short videos, social games as well as other video- and audio-based interactive experiences, such as live chats and mobile karaoke experience. In May 2018, we completed our acquisition of Tantan, a leading social and dating application for younger generation. Tantan, whose primary users consist of young Chinese singles, is designed to help its users to find and establish romantic connections, as well as meet interesting people.

We have built a large user base on Momo since its launch in 2011. Momo’s MAUs increased to 113.3 million in December 2018 from 99.1 million in December 2017 and 81.1 million in December 2016. The increase of Momo’s MAUs in 2018 was primarily attributable to the enriched product and content offerings and our marketing activities. We had 4.1 million paying users on Tantan application from June 1, 2018 to December 31, 2018.

39

Our Momo and Tantan mobile applications can be downloaded and used free of charge, and we generate our revenues from the various services we offer on our platforms. Our revenues increased significantly from RMB3,707.4 million in 2016 to RMB8,886.4 million in 2017 and further to RMB13,408.4 million (US$1,950.2 million) in 2018. We currently generate our revenues from live video service, value-added service, mobile marketing services, mobile games and other services. Our live video service, which was launched in September 2015 and allows users to purchase and send in-show virtual gifts to other users hosting live shows, currently contributes to the largest share of our revenues, generating 79.9% of our net revenues in 2018. We generated 12.1%, 7.8% and 14.0% of our net revenues from value-added services in 2016, 2017 and 2018, respectively, in relation to the membership subscription packages of Momo and Tantan that provide members with additional functions and privileges on our platforms and, starting in the fourth quarter of 2016, virtual gift service, which allows our users to purchase and send virtual gifts to other users outside of the live video service. Mobile marketing services, mobile games and other services contributed 11.9%, 6.4% and 1.2%, respectively, of our revenues in 2016, 5.8%, 2.7% and 0.1%, respectively, of our revenues in 2017 and 3.7%, 1.0% and 1.4%, respectively, of our revenues in 2018. We had a net income of RMB979.0 million, RMB2,144.5 million and RMB2,788.5 million (US$405.6 million) in 2016, 2017 and 2018, respectively.

The Momo Platform

Our Momo platform includes our Momo mobile application and a variety of related properties, features, functionalities, tools and services that we provide to users, customers and platform partners. The Momo mobile application, which is available on Android and iOS platforms, enables users to discover new relationships, expand their social connections and build meaningful interactions. We connect people and facilitate interactions based on location, interests and a variety of recreational activities including live talent shows, short videos, social games as well as other video- and audio-based interactive experiences, such as live chats and mobile karaoke experience. Momo offers a personal and lively way for users to discover interesting people, and facilitates the connecting, communicating, interacting, and content sharing with others. Momo features various social and entertainment features, including Nearby functions, live video, short video service, interest groups and other live interactive experiences. Communications within our platform are supported by multi-media instant messaging tools and other audio- and video-based communication tools and services. Momo’s social features are increasingly integrated with video and audio functions to offer more fun and entertaining contents and to enhance and encourage social interactions between users.

Key features and functionalities offered by the Momo platform include the following:

Nearby People

Nearby People allows users to find out their approximate distance from each other in real time and is one of the primary tools through which users can establish and expand their social relationships on our platform.

Nearby People presents a curated list of nearby users with their profile pictures, relative distances and the time they last checked-in on Momo. The list of nearby people is ordered by our algorithm, which primarily considers the physical proximity and the recency of check-in of the users. All users can customize the list by viewing nearby people by gender, age and some other attributes. Users can initiate contact with nearby users by sending greeting messages and selecting to follow their accounts in order to receive notifications on their status updates. A user who receives a greeting message may then reply and choose to become a Momo friend of the initiator by also following such user. Users can adjust their privacy settings to avoid being seen by strangers or to appear invisible. Our application also allows users to block other users and report inappropriate behaviors.

Nearby Posts

Nearby Posts is an important entry point for users to discover and interact with other users via content sharing and consumption by providing users with a stream of feeds, including photos, videos, music, recorded karaoke songs and other status updates posted by other users. The order of the feeds is defined by our algorithm which computes a number of different factors including physical proximity of the content creator, how recent that post is shared as well as how likely it is for a specific user to interact with such post based on our big data and machine learning technologies. Users can interact with such feeds in a number of different ways such as liking and commenting on the content, as well as checking out the profile pages of the content creators, sending private message and following the creator.

40

Live Video

The Live Video function allows users to live stream a variety of content and activities including talent shows such as singing, dancing and talk shows, as well as casual chatting between broadcasters and viewers. Unlike traditional on-demand video experiences, our live video function allows the viewers to interact with the broadcasters on a real-time basis, thus facilitating a much more dynamic social experience. For example, a user can request a song from the live broadcaster and a broadcaster can connect a viewer to his or her live video channel through video calls. To provide fun and interactive experience between live broadcasters and viewers, the Live Video function offers interesting features such as customized filters and lenses as well as virtual gifts and associated special effects, some of which are enabled by facial recognition and augmented reality technology. For example, a user can pay to put virtual animated images over a broadcaster’s head or face to create an interesting visual effect. Viewers of live video shows may interact with broadcasters using text messages or by sending virtual gifts purchased with virtual currency. In addition to live video channels, our streaming service also supports audio only mode, in order to lower the barriers for broadcasters and users to participate in real-time interactive experience through our live channels.

Other Live Video and Audio Interactive Experiences

We have started to introduce a collection of non-talent show related live video and audio interactive experiences backed by streaming technology since 2017. By designing the user interface differently from that in the “live video” service, which primarily facilitates the one-to-many kind of broadcasting mode, we can better support social interactions among our users in a one-to-one and many-to-many kind of video and audio communication environment. Key experiences we offer include Quick Chat, Parties and Chatroom. Quick Chat is a one-to-one chatting experience available in both video and audio formats. Parties is a group audio and video chat experience usually with moderators organizing recreational activities among the participating users. Chatroom is an audio only group chat experience. We introduced mobile karaoke experience into the Chatroom in 2018. Because Karaoke is a popular offline social and entertainment activity in China, it has quickly gained popularity among our users, making the Chatroom experience one of the major social experiences in terms of usage on our platform. In addition, our streaming service also enables users to play social games while chatting with others on a live basis. For example, we launched Were Wolf in 2017. Inspired by the popular offline dinner party game “Mafia,” the game allows users to engage in group live chat and play different roles according to the story line of the game. Since the beginning of 2018, we have expanded the use cases of the Were Wolf game channels to a variety of other social games supported by audio chat experience.

“Follow” Functions

The Follow tab aggregates content that a user chooses to follow and video content our algorithm “thinks” the user might want to follow based on our big data analytics. There are two subsections within the tab. The “Follow” section under the Follow tab contains a stream of feeds created by people followed by the user while the “Recommended” section features popular short video content that our recommendation engine, based on our big data analytics, believes the user might like or suggests the user to follow. The algorithm of the recommendation engine computes and makes recommendations based on a variety of factors including users’ personal preferences as well as the overall popularity of a specific short video clip.

Other Functions

Other Functions on our platform include instant messaging, user profile page, Diandian and group functions.

Diandian. Diandian is a one-to-one matching function that helps our users discover people that they might be interested in. When activated, our recommendation engine will push a pool of potential matches to a user based on certain algorithms. The user may then interact with the pushes to show if he or she is interested in the recommendation. Only users who have mutually shown interests to each other may become Momo friends and message each other.

Group functions. Our application allows users to create and/or participate in groups created across points of interest and based on locations. Each group is given a shared Momo discussion page on which group members can discuss their common interests, post their photos, exchange messages and organize other online and offline events. Individuals can connect with each other regarding common interests.

User Profile Page

If a user is interested in finding out more about another user on our platform, he or she can review the User Profile page, which is a function that we offer to provide a quick snapshot of a user. Information featured on this page includes profile pictures, account status such as activeness, popularity and wealth level, detailed personal information such as name, age, hometown, horoscope, occupation, relationship status, groups joined, interests and favorite books and movies, the user’s historical posts and videos shared, the broadcasters that the user follows, as well as the user’s travel footprints. The profile page also contains a summary providing insights to a user’s behavioral characteristics. The User Profile Page is integrated with nearly all the other product modules such as the Nearby People, Nearby Posts, Diandian, Live Video and others.

41

Instant Messaging

Our application is supported by instant messaging function, which allows users to communicate with each other using various forms of messages and expressions including text, emoticons, voice recordings, pictures and video messages, or to engage in real-time communication through audio and video chat function. One of the key features of our instant messaging function is that the dialog window presents the distance between the two parties in real time. Senders can see whether their messages have been delivered to or read by the recipient. Our instant messaging feature also allows users to turn voice messages into text, share their location information, invite other users to games, and send virtual gifts and red envelopes to each other.

Tantan

Tantan is a leading social and dating app in China. Tantan, whose primary users consist of young mobile internet users, is designed to help its users find and establish romantic connections, as well as meet interesting people. Tantan had 4.1 million paying users for the period from June 1, 2018 to December 31, 2018 and has become one of the leading choices for young mobile internet users in China to find relationships.

We believe that Tantan strategically complements our Momo platform. First, Tantan’s users are younger on average than Momo’s users, allowing us to expand our footprint among younger demographics. Second, whereas the Momo platform has been primarily focused on connecting people in a broader sense among larger groups and communities, Tantan is primarily focused on one-to-one matching for romantic purposes. Additionally, compared to Momo, Tantan is a younger brand with strong potential to grow its user base and revenues. We believe that our acquisition of Tantan helps us enrich our product line, expand our user base, broaden our social scenarios and strengthen our leading position in China’s open social market.

Tantan’s users can enjoy many of the core features of Tantan for free, including swiping through a pool of users to find potential matches and communicating with the matches through instant messaging tool on the app. However, to enjoy certain premium features, a user must pay a monthly subscription fee or purchase the premium features on an ala carte basis. For example, in order to use unlimited number of the “swipe right” feature which indicates “like,” a Tantan user must pay to subscribe to VIP membership, which was launched in early 2018. In order to get access to a list of users who have “swiped right” on the user, a Tantan user needs to pay to subscribe the “See Who Liked Me” feature, which was launched in July 2018. Tantan users and subscribers may also purchase, on a pay-per-use basis, certain other premium features, such as Super Exposure and Super Likes, which all aim at increasing the paying users’ exposure to other Tantan users.

Monetization Opportunities

We started monetization in July 2013. We currently generate revenues primarily from live video service, value-added service, mobile marketing services, mobile games, and other services.

Live Video Service

We launched our live video service in September 2015, allowing users to purchase and send in-show virtual gifts to other users hosting live shows as broadcasters. Initially, the service adopted an online live concert format whereby certain talented performers were invited to put on live music shows in a professional studio environment. Such shows were broadcasted live in one to four sessions on a daily basis and at pre-announced times. In the fourth quarter of 2015, we opened more live channels in order to enable more performers to put on talent shows to entertain and interact with their audience. The broadcasters are able to “go live” and connect with their audience via their mobile phones, while audience members are able to interact on a real time basis with the broadcasters and other fellow viewers by texting for free or purchasing and sending virtual gifts. We share a portion of the revenues generated with the broadcasters or the talent agencies. Until April 2016, we only offered the service to a limited number of talented performers pre-selected carefully by us. In April 2016, we opened up the service to all the users of our platform so that each one of them can become a broadcaster if they wish. Broadcasters provide live video service on our platform as an individual or as a member of a talent agency. Certain broadcasters are also paying users on our platform. The talent agencies recruit, train and retain the broadcasters. We are committed to provide strong support and resources to broadcasters and talent agencies to offer high-quality content. We are also committed to closely cooperate and develop long-term relationship with broadcasters and talent agencies. Currently, live video service contributes the largest share of our revenues, generating 68.4%, 83.6% and 79.9% of our net revenues in 2016, 2017 and 2018, respectively.

42

Value-added Service

Our value-added service primarily consists of subscription services that provide paying users with additional features and functions as well as privileges on Momo and Tantan and, starting in the fourth quarter of 2016, virtual gift services, which allow Momo users to purchase and send virtual gifts to other users outside of the live video service. We generated 12.1%, 7.8 % and 14.0% of our net revenues from value-added services in 2016, 2017 and 2018, respectively.

Value-added Service on Momo

Membership Subscription. We provide enhanced membership privileges to Momo users who subscribe to our membership package by paying membership fees. Momo’s memberships are currently divided into two tiers, basic and premium. Enhanced privileges for all members include VIP logos, higher limits on the maximum number of users group and the number of users that the member can follow, access to certain special emoticons, the ability to add a short video and a voice recording to the profile page and to see a list of recent visitors to their profile page, and certain other special features unavailable to the non-members. Additional privileges for our premium members include the abilities to check out visitors to their message boards and to remove advertisements from their feeds.

Virtual Gift Service. We launched our virtual gift service on the Momo platform in the fourth quarter of 2016 to enhance users’ social experience. For example, users can purchase and send virtual gifts to other users to increase the response rate to their greetings in Nearby people function. Within the many group chatting experiences that we offer, users can also send each other virtual gifts to facilitate relationship building. We generate revenue from the sales of the virtual gifts.

Value-added Service on Tantan

Tantan offers a variety of premium features and services that users can purchase either through a subscription package or on a pay-per-use basis. For example, a Tantan user can pay to subscribe the VIP membership to enjoy certain privileges such as using unlimited number of the “right swipe” feature, access to “Super Likes,” special badge and location roaming. In addition, a Tantan user can pay to subscribe the “See Who Liked Me” feature, which gives the user access to a list of users who have “swiped right” on that user. Tantan users and subscribers may also purchase, on a pay-per-use basis, certain other premium features, such as Super Exposure and Super Likes, which all aim at increasing the paying users’ exposure to other Tantan users.

Mobile Marketing Services

We seek to provide advertising and marketing solutions to enable our customers to promote their brands and conduct effective marketing activities. We provide our customers with analytical tools to enable them to track and improve the effectiveness of their marketing campaigns on our platform. Our advertising and marketing customers include brand marketers, local merchants, application developers and publishers as well as other small and medium-sized businesses and individuals. Our mobile marketing services currently include the following:

In-feed marketing solutions. We offer advertising units that appear as feeds on Momo platform features such as Nearby People and Nearby Post. Powered by a self-serve advertising system with a real-time bidding mechanism, our in-feed marketing solutions are performance-based and serve a wide range of marketers including application developers, local businesses, brand owners, as well as other small and medium-sized businesses and individuals. We offer advertising units in various formats, including text-based content, pictures, video clips and function that enables direct application downloads. In addition, our advertising system also allows customers to target certain cohorts of users based on their geographic locations, gender, age, type of mobile operating systems and some other parameters. Our customers can use a combination of the various formats and targeting capabilities to create their marketing campaigns more effectively.

43

Display ads. We offer a variety of marketing products in display format, including full screen banner ads that appear before the application is loaded, banners on frequently visited pages and other sponsored images displayed elsewhere within our application. Unlike the in-feed ad units, the display ad units are not sold through the bidding system.

We also offer integrated marketing packages that include multiple advertising units such as feeds, banners, video ads and sponsorships in order to serve a broader sets of marketing objectives of our marketing customers. As the features and functionalities of our platform continue to evolve, we may continue to add new ad format and marketing solutions to our mobile marketing product portfolios. Mobile marketing services contributed 11.9%, 5.8% and 3.7% of our revenues in 2016, 2017 and 2018, respectively.

Mobile Games

As a social networking platform, we intend to offer games that have strong features which we believe will not only increase the interactions between users, but also broaden our revenue sources. Such games may be developed by third parties, with whom we share revenues generated by in-game purchases of virtual items, or developed in-house. We have been scaling back from jointly operated mobile games and instead focusing on self-developed games in order to better align the games offered on our platform with the positioning and strength of Momo as a location-based social platform. Mobile games contributed 6.4%, 2.7% and 1.0% of our revenues in 2016, 2017 and 2018, respectively.

Other Services

Our other services have included paid emoticons, gift mall sales and a TV variety show that we co-produced. Other services have also included other revenue generating services that are immaterial in revenue contribution, or are not considered as part of our strategic focus. Other services contributed 1.2%, 0.1% and 1.4% of our revenues in 2016, 2017 and 2018, respectively.

Technology

Our research and development efforts focus on product development, architecture and technological infrastructures, as well as the security and integrity of our platform to protect our user data.

Our product development endeavors revolve around continuous innovations to help users discover and make new connections as well as building effective interactions. As our user base continues to expand and consumer behaviors constantly evolve, the social demands from the users become increasingly diversified. We make significant investments in technology to optimize our existing products and services and to develop new ones so that we can expand the social use offerings to satisfy the diversifying user demands.

In addition, we are also investing in building and maintaining the technological infrastructures to support the delivery and usage of our products and services in a fast and efficient manner within a safe and secured environment.

Content Management and Monitoring

As an operator of social platforms, we view content management and monitoring as a critical part of our operations. As of the date of this annual report, Momo and Tantan collectively have a dedicated team of over 1,126 personnel reviewing and handling content on our mobile platform for compliance with applicable laws and regulations. They are aided by both proprietary and third-party software and technologies to sweep our platforms and the data being transmitted on a real-time basis around-the-clock. We monitor and screen user information and user generated content against a spam list, which is a list of content and behaviors that we have determined are likely to be indicative of inappropriate or illegal content or illegal activities. Additionally, our users can also easily report fraud if they come across suspicious content, and each user complaint is processed by our content management and monitoring system.

44

Branding and Marketing

Our brand building activities generally comprise purchasing online advertising in the form of texts, banners and videos, placing TV commercials and public relations efforts. We also conduct branding and promotional activities through offline events. In addition, we acquire users for our platforms directly through online marketing channels including mobile advertising platforms such as ByteDance, application stores, search engines and other online advertising networks.

Intellectual Property

We rely on a combination of patent, copyright, trademark and trade secret laws and restrictions on disclosure to protect our intellectual property rights. As of December 31, 2018, we had 13 pending patent applications filed with the State Intellectual Property Office of the PRC. We had registered 398 trademarks and had applied for 262 trademarks with the Trademark Office of the State Administration for Industry & Commerce of the PRC. We had registered 128 software copyrights and 74 copyrights with the PRC National Copyright Administration. We had also registered 83 domain names, including immomo.com, wemomo.com, immomogame.com and momocdn.com.

Seasonality

Historically, there were noticeable downward trends in user activities on our Momo platform as well as revenue growth in the weeks prior to and after the Chinese Lunar New Year. However, due to our limited operating history, the seasonal trends that we have experienced in the past may not apply to, or be indicative of, our future operating results.

Competition

As a mobile social networking platform that also provides live video service, we are subject to intense competition from providers of similar services, as well as potential new types of online services.

Our competitors may have substantially more cash, traffic, technical, performer and other resources, as well as broader product or service offerings and can leverage their relationships based on other products or services to gain a larger share of marketing budgets from customers. We believe that our ability to compete effectively depends upon many factors, including the size, composition and engagement of our user base, our ad targeting capabilities, our pool of popular live broadcasters, market acceptance of our mobile marketing services and online entertainment services, our marketing and selling efforts, and the strength and reputation of our brand. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Business and Industry—The market in which we operate is fragmented and highly competitive. If we are unable to compete effectively for users or user engagement, our business and operating results may be materially and adversely affected.” We also experience significant competition for highly skilled personnel, including management, engineers, designers and product managers. Our growth strategy depends in part on our ability to retain our existing personnel and add additional highly skilled employees. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Business and Industry—The continuing and collaborative efforts of our senior management and key employees are crucial to our success, and our business may be harmed if we were to lose their services.”

Insurance

We do not maintain property insurance, business interruption insurance or general third-party liability insurance, nor do we maintain key-man life insurance.

Regulations

This section sets forth a summary of the most significant rules and regulations that affect our business activities in China or our shareholders’ rights to receive dividends and other distributions from us.

Corporate Laws and Foreign Investment Law

The establishment, operation and management of corporate entities in China are governed by the Company Law of the PRC, or the Company Law, effective in 1994, as amended in 1999, 2004, 2005 and 2013, respectively. The Company Law is applicable to our PRC subsidiaries and consolidated affiliated entities unless the PRC laws on foreign investment have stipulated otherwise.

45

On March 15, 2019, the National People’s Congress approved the Foreign Investment Law, which will take effect on January 1, 2020 and replace the trio of existing laws regulating foreign investment in China, namely, the Sino-foreign Equity Joint Venture Enterprise Law, the Sino-foreign Cooperative Joint Venture Enterprise Law and the Foreign Owned Enterprise Law, together with their implementation rules and ancillary regulations. According to the Foreign Investment Law, “foreign investment” refers to the investment activities directly or indirectly conducted by one or more natural persons, business entities, or other organizations of a foreign country (collectively referred to as “foreign investors”) in China, which includes investments made by foreign investors in China through means stipulated by laws or administrative regulations or other methods prescribed by the State Council. Based on the Foreign Investment Law, it is possible that the prospective laws, administrative regulations or provisions of the State Council may deem contractual arrangements as a way of foreign investment.

According to the Foreign Investment Law, the State Council will publish a catalogue for special administrative measure, or the “negative list,” to provide the scope of “restricted” or “prohibited” industries that have certain restrictions on foreign investment such as market entry clearance. Foreign investment activities in industries not included in the “negative list” are granted national treatment. The “negative list” has yet to be published and it is unclear as to whether a new “negative list” will be published at the time when Foreign Investment Law comes into effect or whether such new “negative list” will be different from the current “negative list” that became effective on July 28, 2018.

We operate our businesses in China through a number our consolidated affiliated entities which are controlled by our PRC subsidiaries through a series of contractual arrangements. Our consolidated affiliated entities hold internet content provider, or ICP, licenses to provide value-added telecommunication services, which is an industry in which foreign investment is “restricted” under the currently effective “negative list.”

Regulations Relating to Telecommunications Services

In September 2000, the State Council issued the Regulations on Telecommunications of China, or the Telecommunications Regulations, to regulate telecommunication activities in China. The telecommunications industry in China is governed by a licensing system based on the classifications of the telecommunications services set forth under the Telecommunications Regulations.

The Ministry of Industry and Information Technology, together with the provincial-level communications administrative bureaus, supervises and regulates the telecommunications industry in China. The Telecommunications Regulations divide the telecommunications services into two categories: infrastructure telecommunications services and value-added telecommunications services. The operation of value-added telecommunications services is subject to the examination, approval and licenses granted by the Ministry of Industry and Information Technology or its provincial-level communications administrative bureaus. According to the Catalog of Classification of Telecommunications Businesses effective in March 2016, provision of information services through the internet, such as the operation of our immomo.com website, is classified as value-added telecommunications services.

Regulations Relating to Foreign Investment in Value-Added Telecommunications Industry

According to the Administrative Rules for Foreign Investment in Telecommunications Enterprises issued by the State Council effective in January 2002, as amended in September 2008 and February 2016, a foreign investor may hold no more than a 50% equity interest in a value-added telecommunications services provider in China and such foreign investor must have experience in providing value-added telecommunications services overseas and maintain a good track record. Due to these regulations, we operate our website through Beijing Momo and its subsidiaries. The most updated version of Guiding Catalog for Foreign Investment Industries, which was promulgated by the MOFCOM and the National Development and Reform Commission and became effective from July 28, 2018, or the Guiding Catalog, imposes the 50% restrictions on foreign ownership in value-added telecommunications business except for e-commerce business as well.

46

The Circular on Strengthening the Administration of Foreign Investment in and Operation of Value-added Telecommunications Business, or the Circular, issued by the former Ministry of Information Industry in July 2006, reiterated the regulations on foreign investment in telecommunications businesses, which require foreign investors to set up foreign-invested enterprises and obtain an internet content provider, or ICP, license to conduct any value-added telecommunications business in China. Under the Circular, a domestic company that holds an ICP license is prohibited from leasing, transferring or selling the license to foreign investors in any form, and from providing any assistance, including providing resources, sites or facilities, to foreign investors that conduct value-added telecommunications business illegally in China. Furthermore, certain relevant assets, such as the relevant trademarks and domain names that are used in the value-added telecommunications business must be owned by the local ICP license holder or its shareholders. The Circular further requires each ICP license holder to have the necessary facilities for its approved business operations and to maintain such facilities in the regions covered by its license. In addition, all value-added telecommunications service providers are required to maintain network and information security in accordance with the standards set forth under the relevant PRC regulations. If an ICP license holder fails to comply with the requirements in the Circular and also fails to remedy such non-compliance within a specified period of time, the Ministry of Industry and Information Technology or its local counterparts have the discretion to take administrative measures against such license holder, including revoking its ICP license. Beijing Momo, the operator of our website, owns the relevant domain names and registered trademarks and has the necessary personnel to operate the website.

Regulations on Broadcasting Audio/Video Programs through the Internet

On April 13, 2005, the State Council announced Several Decisions on Investment by Non-state-owned Companies in Culture-related Business in China. These decisions encourage and support non-state-owned companies to enter certain culture-related business in China, subject to restrictions and prohibitions for investment in audio/video broadcasting, website news and certain other businesses by non-state-owned companies. These decisions authorize the SARFT and the Ministry of Culture to adopt detailed implementing rules according to these decisions.

On December 20, 2007, the SARFT and the MIIT jointly issued the Rules for the Administration of Internet Audio and Video Program Services, commonly known as Circular 56, which came into effect as of January 31, 2008 and was amended on August 28, 2015. Circular 56 reiterates the requirement set forth in the Audio/Video Broadcasting Rules that online audio/video service providers must obtain a license from the SARFT. Furthermore, Circular 56 requires all online audio/video service providers to be either wholly state-owned or state-controlled. According to relevant official answers to press questions published on the SARFT’s website dated February 3, 2008, officials from the SARFT and the MIIT clarified that online audio/video service providers that already had been operating lawfully prior to the issuance of Circular 56 may re-register and continue to operate without becoming state-owned or controlled, provided that such providers have not engaged in any unlawful activities. This exemption will not be granted to online audio/video service providers established after Circular 56 was issued. Such policies have been reflected in the Application Procedure for Audio/Video Program Transmission License.

On April 1, 2010, the SARFT issued the Internet Audio/Video Program Services Categories (Provisional), or the Provisional Categories, as further amended on March 10, 2017, which classified internet audio/video programs into four categories.

In 2009, the SARFT released a Notice on Strengthening the Administration of Online Audio/Video Content. This notice reiterated, among other things, that all movies and television shows released or published online must comply with relevant regulations on the administration of radio, film and television. In other words, these movies and television shows, whether produced in the PRC or overseas, must be pre-approved by SARFT, and the distributors of these movies and television shows must obtain an applicable permit before releasing any such movie or television show. In 2012, the SARFT and the State Internet Information Office of the PRC issued a Notice on Improving the Administration of Online Audio/Video Content Including Internet Drama and Micro Films. In 2014, SARFT released a Supplemental Notice on Improving the Administration of Online Audio/Video Content Including Internet Drama and Micro Films. This notice stresses that entities producing online audio/video content, such as internet dramas and micro films, must obtain a permit for radio and television program production and operation, and that online audio/video content service providers should not release any internet dramas or micro films that were produced by any entity lacking such permit. For internet dramas or micro films produced and uploaded by individual users, the online audio/video service providers transmitting such content will be deemed responsible as a producer. Further, under this notice, online audio/video service providers can only transmit content uploaded by individuals whose identity has been verified and such content shall comply with the relevant content management rules. This notice also requires that online audio/video content, including internet drama and micro films, be filed with the relevant authorities before release.

47

On April 25, 2016, the SARFT promulgated the Provisions on the Administration of Private Network and Targeted Transmission Audio/Video Program Services, which became effective as of June 1, 2016 and applies to the provision of radio, TV programs and other audio/video programs to targeted audience on TV and all types of handheld electronic equipment. The Provision covers the internet and other information networks as targeted transmission channels, including the provision of content, integrated broadcast control, transmission and distribution and other activities conducted in such forms as Internet protocol television (IPTV), private network mobile TV and Internet TV. Anyone who provides private network and targeted transmission audio/video program services must obtain an audio/video program transmission license, with a term of three years, issued by the SARFT and operate its business pursuant to the scope as provided in such license. Foreign-invested enterprises are not allowed to engage in the above referenced business.

On July 1, 2016, the MOC promulgated Notice on Strengthening the Administration of Network Performance, which regulates the behavior of entities operating network performance and performers. Entities operating network performance shall be responsible for the service and content post on their website which are provided by performers, perfect the content management mechanism, and shut down the channel and stop the spreading as soon as realize any network performance in violation of relevant laws and regulations. Network performers shall be responsible for their performances and shall not perform any program containing violence, pornography, or other similarly prohibited elements. The cultural administration authorities or cultural market enforcement authorities of relevant government supervise entities operating network performance and shall investigate all entities operating network performance in their thoroughly and publish any fine or action results or blacklist in time.

On September 2, 2016, the SARFT issued a Notice on Problems regarding Strengthening the Administration of Internet Audio/Video Programs Live Broadcasting Services, which provides that the provision of audio/video live broadcasting of important political, military, economic, social, cultural, sports and other activities and events requires an audio/video program transmission license which covers item (5) under internet audio/video program services category I, and the provision of audio/video live broadcasting of cultural activities by general social organizations, sports events and like activities requires an audio/video program transmission license which covers item (7) under internet audio/video program services category II.

On November 4, 2016, the Cyberspace Administration of China promulgated the Provisions on the Administration of Online Live Broadcasting Services, which became effective as of December 1, 2016. Such Provisions provides that anyone who provides online live broadcasting services through online performances, internet video/audio programs and so forth, shall obtain relevant qualifications as required by laws and regulations.

In November 2016, the SARFT issued a Notice on Strengthening the Administration of Audio/Video Programs Transmission on Weibo, Wechat and Other Internet Social Networking Platforms, which further clarifies that anyone who operates internet audio/video services through Weibo, Wechat and other internet social networking platforms must obtain an audio/video program transmission license and operate its business pursuant to the scope as provided in such license.

As of the date of this annual report, we hold an internet audio/video program transmission license through Zhejiang Shengdian, a wholly-owned subsidiary that we acquired in March 2017.

Regulations on Online Comics and Internet Cultural Products

The Interim Administrative Provisions on Internet Culture was promulgated by MOC on February 17, 2011 and became effective on April 1, 2011. Pursuant to the Interim Administrative Provisions on Internet Culture, online comics are deemed to be online culture products, and any entity engaged in producing, transmitting and distributing online culture products shall apply for an internet culture operation license that includes the business scope of actual online activities. As of the date of this annual report, we have obtained an internet culture operation license and received the approval to expand the scope of the license to cover the operation of comic and animation products.

Regulations on Internet Publication and Cultural Products

The Administrative Measures for Internet Publication Service, or Internet Publication Measures, were jointly promulgated by the SARFT and the MIIT on February 4, 2016 and became effective on March 10, 2016. The Internet Publication Measures superseded the Tentative Measures for Internet Publication Administration, which were jointly promulgated by the SARFT and the MIIT in 2002. The Internet Publication Measures define internet publication service and internet publication item, and publication of internet publication item via the internet requires an internet publishing license. Pursuant to the Internet Publication Measures, online game constitutes an internet publication item and therefore, an online game operator shall obtain an internet publishing license so that it can directly offer its online games to the public in the PRC. As of the date of this annual report, we have not yet obtained an internet publishing license, and are in the process of preparing the application documents.

Regulations on Online Games and Foreign Ownership Restrictions

Pursuant to the Guidance Catalog, the internet culture business (other than online music business) falls within the category of industries prohibiting foreign investment. On February 17, 2011, the Ministry of Culture issued the revised Interim Provisions on the Administration of Internet Culture, or the Internet Culture Interim Provisions, effective as of April 1, 2011 and amended on December 15, 2017. According to the Internet Culture Interim Provisions, “internet cultural products” are defined as including the online games specially produced for Internet and games reproduced or provided through Internet. Provision of operating Internet cultural products and related services is subject to the approval of the Ministry of Culture or its provincial counterpart.

On June 3, 2010, the Ministry of Culture promulgated the Provisional Administration Measures of Online Games, or the Online Game Measures, which came into effect on August 1, 2010. The Online Game Measures governs the research, development and operation of online games and the issuance and trading services of virtual currency. Under the Online Game Measures, all operators of online games, issuers of virtual currencies and providers of virtual currency trading services, or Online Game Business Operators, are required to obtain internet culture operation licenses. An internet culture operation license is valid for three years and in case of renewal, the renewal application should be submitted 30 days prior to the expiry date of such license.

In addition, Online Game Business Operators should request the valid identity certificate of game users for registration, and notify the public 60 days ahead of the termination of any online game operations or the transfer of online game operational rights. Online game business operators are also prohibited from (i) setting compulsory battles in the online games without game users’ consent; (ii) advertising or promoting the online games that contain prohibited content, such as anything that compromise state security or divulges state secrets; and (iii) inducing game users to input legal currencies or virtual currencies to gain online game products or services, by way of random draw or other incidental means. The Online Game Measures also states that the state cultural administration authorities will formulate the compulsory clauses of a standard online game service agreement, which have been promulgated on July 29, 2010 and are required to be incorporated into the service agreement entered into between online game business operators and game users, with no conflicts with the rest of clauses in such service agreements.

On July 11, 2008, the General Office of the State Council promulgated the Regulation on Main Functions, Internal Organization and Staffing of the General Administration of Press and Publication, or the Regulation on Three Provisions. On September 14, 2009, the Central Organization Establishment Commission issued the corresponding interpretations, or the Interpretations on Three Provisions. The Regulation on Three Provisions and the Interpretation on Three Provisions granted the Ministry of Culture overall jurisdiction to regulate the online game industry, and granted the General Administration of Press and Publication the authority to issue approvals for the internet publication of online games. Specifically, (i) the Ministry of Culture is empowered to administrate online games (other than the pre-examination and approval before internet publication of online games); (ii) subject to the Ministry of Culture’s overall administration, General Administration of Press and Publication is responsible for the pre-examination and approval of the internet publication of online games; and (iii) once an online game is launched, the online game will be only administrated and regulated by the Ministry of Culture. As of March 31, 2019, 11 of the 12 online games we offered had completed the filing with the Ministry of Culture. If we fail to complete, obtain or maintain any of the required licenses or approvals or make the necessary filings, we may be subject to various penalties, such as confiscation of the net revenues that were generated through online games, the imposition of fines and the discontinuation or restriction of our operations of online games.

On September 28, 2009, the General Administration of Press and Publication, the National Copyright Administration and the National Working Group to Eliminate Pornography and Illegal Publications jointly issued the Circular on Consistent Implementation of the Stipulation on the Three Provisions of the State Council and the Relevant Interpretations of the State Commission for Public Sector Reform and the Further Strengthening of the Pre-examination and approval of Online Games and the Approval and Examination of Imported Online Games, or the GAPP Notice. The GAPP Notice explicitly prohibits foreign investors from directly or indirectly engaging in online game business in China, including through consolidated affiliated entities. Foreign investors are not allowed to indirectly control or participate in PRC operating companies’ online game operations, whether (i) by establishing other joint ventures, entering into contractual arrangements or providing technical support for such operating companies; or (ii) in a disguised form such as by incorporating or directing user registration, user account management or game card consumption into online game platforms that are ultimately controlled or owned by foreign companies. The GAPP Notice reiterates that the General Administration of Press and Publication is responsible for the examination and approval of the import and publication of online games and states that providing downloading services of the online game contents to the public through the internet is considered a publication activity, which is subject to approval from the General Administration of Press and Publication. Violations of the GAPP Notice will result in severe penalties. For detailed analysis, see “Risk Factors—Risks Related to Our Corporate Structure—If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with PRC regulations on foreign investment in internet and other related businesses, or if these regulations or their interpretation change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations.”

49

On May 24, 2016, the SARFT promulgated the Circular on the Administration over Mobile Game Publishing Services, which became effective as of July 1, 2016. The Circular provides that game publishing service entities shall be responsible for examining the contents of their games and applying for game publication numbers. To apply for publication of domestically-developed mobile puzzle games that are not related to political, military, national or religious topics or contents and have no or simple story lines, entities shall submit the required documents to provincial publication administrative departments at least 20 working days prior to the expected date of online publication (public beta). Entities applying for publication of domestically-developed mobile games that are not included in abovementioned category shall go through stricter procedures, including submitting manager accounts for content review and testing accounts for game anti-indulgence system. Game publishing service entities must set up a specific page to display the information approved by the SARFT, including copyright owner of the game, publishing service entity, approval number, publication number and others, and shall take charge of examining and recording daily updates of the game. For mobile games (including pre-installed mobile games) that have been published and operated online before implementation of this Circular, to maintain the publication and operation of such games online, relevant approval procedures shall be made up by the game publishing service entities and enterprises with the provincial publication administrative departments before December 31, 2016 as required by this Circular. Otherwise, they shall cease to be published or operated online.

Regulation on Information Security

The Standing Committee of the National People’s Congress promulgated the Cyber Security Law of the PRC, or the Cyber Security Law, which became effective on June 1, 2017, to protect cyberspace security and order. Pursuant to the Cyber Security Law, any individual or organization using the network must comply with the constitution and the applicable laws, follow the public order and respect social moralities, and must not endanger cyber security, or engage in activities by making use of the network that endanger the national security, honor and interests, or infringe on the fame, privacy, intellectual property and other legitimate rights and interests of others. The Cyber Security Law sets forth various security protection obligations for network operators, which are defined as “owners and administrators of networks and network service providers,” including, among others, complying with a series of requirements of tiered cyber protection systems; verifying users’ real identity; localizing the personal information and important data gathered and produced by key information infrastructure operators during operations within the PRC; and providing assistance and support to government authorities where necessary for protecting national security and investigating crimes. To comply with these laws and regulations, we have adopted security policies and measures to protect our cyber system and user information.

Regulations Relating to Internet Content and Information Security

The Administrative Measures on Internet Information Services specify that internet information services regarding news, publications, education, medical and health care, pharmacy and medical appliances, among other things, are to be examined, approved and regulated by the relevant authorities. Internet information providers are prohibited from providing services beyond those included in the scope of their ICP licenses or filings. Furthermore, these measures clearly specify a list of prohibited content. Internet information providers are prohibited from producing, copying, publishing or distributing information that is humiliating or defamatory to others or that infringes the lawful rights and interests of others. Internet information providers that violate the prohibition may face criminal charges or administrative sanctions by the PRC authorities. Internet information providers must monitor and control the information posted on their websites. If any prohibited content is found, they must remove the offensive content immediately, keep a record of it and report it to the relevant authorities. Beijing Momo, as an ICP license holder, is subject to these measures.

50

Internet information in China is also regulated and restricted from a national security standpoint. The Standing Committee of the National People’s Congress has enacted the Decisions on Maintaining Internet Security, which may subject violators to criminal punishment in China for any effort to: (i) gain improper entry into a computer or system of strategic importance; (ii) disseminate politically disruptive information; (iii) leak state secrets; (iv) spread false commercial information; or (v) infringe intellectual property rights. The Ministry of Public Security has promulgated measures that prohibit use of the internet in ways which, among other things, result in a leakage of state secrets or a spread of socially destabilizing content. As an ICP license holder, Beijing Momo is subject to the laws and regulations relating to information security.

In August 2013, the MOC issued the Administration Measures on Content Review by Internet Culture Operating Entities, or the Content Review Measures, which became effective on December 1, 2013. According to the Content Review Measures, an internet culture operating entity shall censor and review its products and services to be provided to the public to ensure that such products and services do not contain any content prohibited by law, and the censor record shall be kept for at least two years. Internet culture operating entities shall adopt technical measures to conduct real-time censor over the products and services, set up internal content control department and establish content control policies. If the internet culture operating entity identifies any illegal content, it shall immediately suspend the products or services containing such content and preserve relevant record, and, in the event that such illegal content might lead to material issues, report to provincial branch of MOC.

Regulations on Anti-fatigue Compliance System and Real-name Registration System

On April 15, 2007, eight PRC government authorities, including the General Administration of Press and Publication, the Ministry of Education, the Ministry of Public Security and the Ministry of Industry and Information Technology, jointly issued the Notice on Protecting Minors Mental and Physical Health and Implementation of Online Game Anti-fatigue System, which requires the implementation of an anti-fatigue compliance system and a real-name registration system by all PRC online game operators. Under the anti-fatigue compliance system, three hours or less of continuous playing by minors, defined as game players under 18 years of age, is considered to be “healthy”, three to five hours is deemed “fatiguing”, and five hours or more is deemed “unhealthy.” Game operators are required to reduce the value of in-game benefits to a game player by half if it discovers that the amount of a time a game player spends online has reached the “fatiguing” level, and to zero in the case of the “unhealthy” level.

To identify whether a game player is a minor and thus subject to the anti-fatigue compliance system, a real-name registration system should be adopted to require online game players to register their real identity information before playing online games. Pursuant to a notice issued by the relevant eight government authorities on July 1, 2011, online game operators must submit the identity information of game players to the National Citizen Identity Information Center, a subordinate public institution of the Ministry of Public Security, for verification as of October 1, 2011.

Regulations Relating to Internet Information Services and Content of Internet Information

In September 2000, the State Council issued the Administrative Measures on Internet Information Services, or the Internet Measures, which is amended on January 8, 2011, to regulate the provision of information services to online users through the internet. According to the Internet Measures, internet information services are divided into two categories: services of an operative nature and services of a non-operative nature. Our business conducted through our immomo.com website involves operating internet information services, which requires us to obtain an ICP license. If an internet information service provider fails to obtain an ICP license, the relevant local branch of the Ministry of Industry and Information Technology may levy fines, confiscate its income or even block its website. When the ICP service involves areas of news, publication, education, medical treatment, health, pharmaceuticals and medical equipment, and if required by law or relevant regulations, specific approval from the respective regulatory authorities must be obtained prior to applying for the ICP license from the Ministry of Industry and Information Technology or its provincial level counterpart. Our affiliated PRC entity, Beijing Momo, currently holds an ICP license issued by Beijing Communications Administration, a local branch of the Ministry of Industry and Information Technology. Our ICP license will expire in January 2022.

51

Regulations Relating to Privacy Protection

As an internet content provider, we are subject to regulations relating to protection of privacy. In recent years, PRC government authorities have enacted laws and regulations on internet use to protect personal information from any unauthorized disclosure. The Administrative Measures on Internet Information Services prohibit ICP service operators from insulting or slandering a third party or infringing upon the lawful rights and interests of a third party. Under the Several Provisions on Regulating the Market Order of Internet Information Services, issued by the Ministry of Industry and Information Technology in 2011, an ICP service operator may not collect any user personal information or provide such information to third parties without the consent of a user. An ICP service operator must expressly inform the users of the method, content and purpose for the collection and processing of such user personal information and may only collect such information necessary for the provision of its services. An ICP service operator is also required to properly keep the user personal information, and in case of any leak or likely leak of the user personal information, the ICP service operator must take immediate remedial measures and, in severe circumstances, to make an immediate report to the telecommunications regulatory authority. In addition, pursuant to the Decision on Strengthening the Protection of Online Information issued by the Standing Committee of the National People’s Congress in December 2012 and the Order for the Protection of Telecommunication and Internet User Personal Information issued by the Ministry of Industry and Information Technology in July 2013, any collection and use of user personal information must be subject to the consent of the user, abide by the principles of legality, rationality and necessity and be within the specified purposes, methods and scopes. An ICP service operator must also keep such information strictly confidential, and is further prohibited from divulging, tampering or destroying of any such information, or selling or providing such information to other parties. Any violation of the above decision or order may subject the ICP service operator to warnings, fines, confiscation of illegal gains, revocation of licenses, cancelation of filings, closedown of websites or even criminal liabilities. We are subject to these regulations as an online business operator.

Regulations Relating to Taxation

In January 2008, the PRC Enterprise Income Tax Law took effect. The PRC Enterprise Income Tax Law applies a uniform 25% enterprise income tax rate to both foreign-invested enterprises and domestic enterprises, except where tax incentives are granted to special industries and projects. Under the PRC Enterprise Income Tax Law and its implementation regulations, dividends generated from the business of a PRC subsidiary after January 1, 2008 and payable to its foreign investor may be subject to a withholding tax rate of 10% if the PRC tax authorities determine that the foreign investor is a non-resident enterprise, unless there is a tax treaty with China that provides for a preferential withholding tax rate. Distributions of earnings generated before January 1, 2008 are exempt from PRC withholding tax.

Under the PRC Enterprise Income Tax Law, an enterprise established outside China with “de facto management bodies” within China is considered a “resident enterprise” for PRC enterprise income tax purposes and is generally subject to a uniform 25% enterprise income tax rate on its worldwide income. A circular issued by the State Administration of Taxation in April 2009 regarding the standards used to classify certain Chinese-invested enterprises controlled by Chinese enterprises or Chinese enterprise groups and established outside of China as “resident enterprises” clarified that dividends and other income paid by such PRC “resident enterprises” will be considered PRC-source income and subject to PRC withholding tax, currently at a rate of 10%, when paid to non-PRC enterprise shareholders. This circular also subjects such PRC “resident enterprises” to various reporting requirements with the PRC tax authorities. Under the implementation regulations to the PRC Enterprise Income Tax Law, a “de facto management body” is defined as a body that has material and overall management and control over the manufacturing and business operations, personnel and human resources, finances and properties of an enterprise. In addition, the tax circular mentioned above specifies that certain PRC-invested overseas enterprises controlled by a Chinese enterprise or a Chinese enterprise group in the PRC will be classified as PRC resident enterprises if the following are located or resided in the PRC: senior management personnel and departments that are responsible for daily production, operation and management; financial and personnel decision making bodies; key properties, accounting books, the company seal, and minutes of board meetings and shareholders’ meetings; and half or more of the senior management or directors who have the voting rights.

52

Pursuant to the Arrangement between Mainland China and the Hong Kong Special Administrative Region for the Avoidance of Double Taxation and Tax Evasion on Income, the withholding tax rate in respect to the payment of dividends by a PRC enterprise to a Hong Kong enterprise is reduced to 5% from a standard rate of 10% if the Hong Kong enterprise directly holds at least 25% of the PRC enterprise. Pursuant to the Notice of the State Administration of Taxation on the Issues concerning the Application of the Dividend Clauses of Tax Agreements, or Circular 81, a Hong Kong resident enterprise must meet the following conditions, among others, in order to enjoy the reduced withholding tax: (i) it must be a company; (ii) it must directly own the required percentage of equity interests and voting rights in the PRC resident enterprise; and (iii) it must have directly owned such required percentage in the PRC resident enterprise throughout the 12 months prior to receiving the dividends. Furthermore, the Administrative Measures for Non-Resident Taxpayer to Enjoy Treatments under Tax Treaties, which became effective in November 2015, require that non-resident taxpayers may enjoy treatments under tax treaties on their own during the tax filings by themselves or through withholding agents, and be subject to administration by relevant tax authorities afterwards. There are also other conditions for enjoying the reduced withholding tax rate according to other relevant tax rules and regulations. Accordingly, Momo Technology HK Company Limited may be able to benefit from the 5% withholding tax rate for the dividends it receives from Beijing Momo, if it satisfies the conditions prescribed under Circular 81 and other relevant tax rules and regulations, and obtain the approvals as required. However, according to Circular 81, if the relevant tax authorities consider the transactions or arrangements we have are for the primary purpose of enjoying a favorable tax treatment, the relevant tax authorities may adjust the favorable withholding tax in the future.

In January 2009, the SAT promulgated the Provisional Measures for the Administration of Withholding of Enterprise Income Tax for Non-resident Enterprises, or the Non-resident Enterprises Measures, pursuant to which entities that have direct obligation to make certain payments to a non-resident enterprise shall be the relevant tax withholders for such non-resident enterprise. Further, the Non-resident Enterprises Measures provides that, in case of an equity transfer between two non-resident enterprises which occurs outside China, the non-resident enterprise which receives the equity transfer payment shall, by itself or engage an agent to, file tax declaration with the PRC tax authority located at place of the PRC company whose equity has been transferred, and the PRC company whose equity has been transferred shall assist the tax authorities to collect taxes from the relevant non-resident enterprise. On April 30, 2009, the MOF and the SAT jointly issued the Notice on Issues Concerning Process of Enterprise Income Tax in Enterprise Restructuring Business, or Circular 59. On December 10, 2009, the SAT issued the Notice on Strengthening the Administration of the Enterprise Income Tax concerning Proceeds from Equity Transfers by Non-resident Enterprises, or Circular 698. Both Circular 59 and Circular 698 became effective retroactively as of January 1, 2008. By promulgating and implementing these two circulars, the PRC tax authorities have enhanced their scrutiny over the direct or indirect transfer of equity interests in a PRC resident enterprise by a non-resident enterprise.

On February 3, 2015, the SAT issued a Public Notice on Several Issues Relating to Enterprise Income Tax on Transfer of Assets between Non-resident Enterprises, or Public Notice 7, to supersede existing provisions in relation to the Indirect Transfer as set forth in Circular 698, while the other provisions of Circular 698 remain in force. Public Notice 7 introduces a new tax regime that is significantly different from that under Circular 698. Public Notice extends its tax jurisdiction to capture not only Indirect Transfer as set forth under Circular 698 but also transactions involving transfer of immovable property in China and assets held under the establishment and place, in China of a foreign company through the offshore transfer of a foreign intermediate holding company. Public Notice 7 also addresses transfer of the equity interest in a foreign intermediate holding company widely. In addition, Public Notice 7 provides clearer criteria than Circular 698 on how to assess reasonable commercial purposes and introduces safe harbor scenarios applicable to internal group restructurings. However, it also brings challenges to both the foreign transferor and transferee of the Indirect Transfer as they have to make self-assessment on whether the transaction should be subject to PRC tax and to file or withhold the PRC tax accordingly. In October 2017, the SAT issued the Announcement of the State Administration of Taxation on Issues Concerning the Withholding of Non-resident Enterprise Income Tax at Source, or Bulletin 37, which came into effect on December 1, 2017. The Bulletin 37 replaced and superseded, among other circulars, the Non-resident Enterprises Measures and Circular 698, and further clarifies the practice and procedures of the withholding of non-resident enterprise income tax. Where a non-resident enterprise transfers taxable assets indirectly by disposing of the equity interests of an overseas holding company, which is an Indirect Transfer, the non-resident enterprise as either the transferor or the transferee, or the PRC entity that directly owns the taxable assets, may report such Indirect Transfer to the relevant tax authority.

Where non-resident investors were involved in our private equity financing, if such transactions were determined by the tax authorities to lack reasonable commercial purpose, we and our non-resident investors may become at risk of being taxed under Bulletin 37 and Public Notice 7 and may be required to expend valuable resources to comply with Bulletin 37 and Public Notice 7 or to establish that we should not be taxed under Bulletin 37 and Public Notice 7.

The PRC tax authorities have the discretion under SAT Circular 59, Bulletin 37 and Public Notice 7 to make adjustments to the taxable capital gains based on the difference between the fair value of the equity interests transferred and the cost of investment.

Value Added Tax

On January 1, 2012, the Chinese State Council officially launched a pilot value-added tax (“VAT”) reform program, or Pilot Program, applicable to businesses in selected industries. Businesses in the Pilot Program would pay VAT instead of business tax. The Pilot Industries in Shanghai included industries involving the leasing of tangible movable property, transportation services, research and development and technical services, information technology services, cultural and creative services, logistics and ancillary services, certification and consulting services. Revenues generated by advertising services, a type of “cultural and creative services,” are subject to the VAT tax rate of 6%. According to official announcements made by competent authorities in Beijing and Guangdong province, Beijing launched the same Pilot Program on September 1, 2012, and Guangdong province launched it on November 1, 2012. On May 24, 2013, the Ministry of Finance, or the MoF, and the State Administration of Taxation, or the SAT, issued the Circular on Tax Policies in the Nationwide Pilot Collection of Value Added Tax in Lieu of Business Tax in the Transportation Industry and Certain Modern Services Industries, or the Circular 37. The scope of certain modern services industries under the Circular 37 extends to the inclusion of radio and television services. On August 1, 2013, the Pilot Program was implemented throughout China. On December 12, 2013, the MoF and the SAT issued the Circular on the Inclusion of the Railway Transport Industry and Postal Service Industry in the Pilot Collection of Value-added Tax in Lieu of Business Tax, or Circular 106. Among the other things, Circular 106 abolished Circular 37, and refined the policies for the Pilot Program. On April 29, 2014, the MoF and the SAT issued the Circular on the Inclusion of Telecommunications Industry in the Pilot Collection of Value-added Tax in Lieu of Business Tax. On March 23, 2016, the MoF and the SAT issued the Circular on Comprehensively Promoting the Pilot Program of the Collection of Value-added Tax in Lieu of Business Tax. Effective from May 1, 2016, the PRC tax authorities collect VAT in lieu of Business Tax in all regions and industries. All of our entities were subject to VAT at the rate of 6% for services provided and 16% for goods sold which are not listed in Article 2 Sub-article 2 of the Provisional Regulations on Value Added Tax of the PRC as of December 31, 2018.

Regulations Relating to Copyright and Trademark Protection

China has adopted legislation governing intellectual property rights, including copyrights and trademarks. China is a signatory to major international conventions on intellectual property rights and is subject to the Agreement on Trade Related Aspects of Intellectual Property Rights as a result of its accession to the World Trade Organization in December 2001.

Copyright. The National People’s Congress amended the Copyright Law in 2001 and 2010 to widen the scope of works and rights that are eligible for copyright protection. The amended Copyright Law extends copyright protection to Internet activities, products disseminated over the Internet and software products. In addition, there is a voluntary registration system administered by the China Copyright Protection Center. To address copyright infringement related to content posted or transmitted over the internet, the National Copyright Administration and former Ministry of Information Industry jointly promulgated the Administrative Measures for Copyright Protection Related to the Internet in April 2005. These measures became effective in May 2005. To comply with these laws and regulations, we have implemented internal procedures to monitor and review the content we have been licensed from content providers before they are released on our platform and remove any infringing content promptly after we receive notice of infringement from the legitimate rights holder.

On December 20, 2001, the State Council promulgated the new Regulations on Computer Software Protection, effective from January 1, 2002, which are intended to protect the rights and interests of the computer software copyright holders and encourage the development of software industry and information economy. In the PRC, software developed by PRC citizens, legal persons or other organizations is automatically protected immediately after its development, without an application or approval. Software copyright may be registered with the designated agency and if registered, the certificate of registration issued by the software registration agency will be the primary evidence of the ownership of the copyright and other registered matters. On February 20, 2002, the National Copyright Administration of the PRC introduced the Measures on Computer Software Copyright Registration, which outline the operational procedures for registration of software copyright, as well as registration of software copyright license and transfer contracts. The Copyright Protection Center of China is mandated as the software registration agency under the regulations.

The State Council and the National Copyright Administration have promulgated various rules and regulations and rules relating to protection of software in China, including the Regulations on Protection of Computer Software promulgated by State Council on January 30, 2013 and effective since March 1, 2013, and the Measures for Registration of Copyright of Computer Software promulgated by SARFT on February 20, 2002 and effective since the same date. According to these rules and regulations, software owners, licensees and transferees may register their rights in software with the National Copyright Administration or its local branches and obtain software copyright registration certificates. Although such registration is not mandatory under PRC law, software owners, licensees and transferees are encouraged to go through the registration process and registered software rights may be entitled to better protections. As of December 31, 2018, we had registered 128 software copyrights in China.

54

Trademark. The PRC Trademark Law, adopted in 1982 and revised in 1993, 2001 and 2013 respectively, protects the proprietary rights to registered trademarks. The Trademark Office under the State Administration for Industry and Commerce handles trademark registrations and may grant a term of ten years for registered trademarks, which may be extended for another ten years upon request. Trademark license agreements shall be filed with the Trademark Office for record. In addition, if a registered trademark is recognized as a well-known trademark, the protection of the proprietary right of the trademark holder may reach beyond the specific class of the relevant products or services. As of December 31, 2018, we had 398 registered trademarks and 262 trademark applications in China.

Regulations Relating to Foreign Exchange

Pursuant to the Regulations on the Administration of Foreign Exchange issued by the State Council and effective in 1996, as amended in January 1997 and August 2008, respectively, current account transactions, such as the sale or purchase of goods, are not subject to PRC governmental approvals. Certain organizations in the PRC, including foreign-invested enterprises, may purchase, sell and/or remit foreign currencies at certain banks authorized to conduct foreign exchange business upon providing valid commercial documents. However, approval of the PRC State Administration of Foreign Exchange, or SAFE, is required for capital account transactions.

In August 2008, SAFE issued a circular on the conversion of foreign currency into Renminbi by a foreign-invested company that regulates how the converted Renminbi may be used, or the SAFE Circular 142. The circular requires that the registered capital of a foreign-invested enterprise converted into Renminbi from foreign currencies may only be utilized for purposes within its business scope. For example, such converted amounts may not be used for investments in or acquisitions of other companies, which can inhibit the ability of companies to consummate such transactions. In addition, SAFE strengthened its oversight of the flow and use of the Renminbi registered capital of foreign-invested enterprises converted from foreign currencies. The use of such Renminbi capital may not be changed without SAFE’s approval, and may not in any case be used to repay Renminbi loans if the proceeds of such loans have not been utilized. Furthermore, SAFE promulgated a circular in November 2010, which, among other things, requires the authenticity of settlement of net proceeds from offshore offerings to be closely examined and the net proceeds to be settled in the manner described in the offering documents. Violations may result in severe penalties, such as heavy fines.

In November 2012, SAFE promulgated the Circular of Further Improving and Adjusting Foreign Exchange Administration Policies on Foreign Direct Investment which substantially amends and simplifies the current foreign exchange procedure. Pursuant to this circular, the opening of various special purpose foreign exchange accounts (e.g. pre-establishment expenses account, foreign exchange capital account, guarantee account), the reinvestment of RMB proceeds by foreign investors in the PRC, and remittance of foreign exchange profits and dividends by a foreign-invested enterprise to its foreign shareholders no longer require the approval or verification of SAFE, and multiple capital accounts for the same entity may be opened in different provinces, which was not possible before. In addition, SAFE promulgated the Circular on Printing and Distributing the Provisions on Foreign Exchange Administration over Domestic Direct Investment by Foreign Investors and the Supporting Documents in May 2013, which specifies that the administration by SAFE or its local branches over direct investment by foreign investors in the PRC shall be conducted by way of registration and banks shall process foreign exchange business relating to the direct investment in the PRC based on the registration information provided by SAFE and its branches.

In April 8, 2015, SAFE promulgated the Circular on Reforming the Management Approach Regarding the Foreign Exchange Capital Settlement of Foreign-invested Enterprises, which will, upon its effective date as of June 1, 2015, supersedes the SAFE Circular 142. This circular provides that, among other things, the foreign-invested company may convert the foreign currency in its capital account into RMB on a “at will” basis and the RMB funds so converted can be used for equity investments provided that equity investment is included in the business scope of such foreign-invested company.

On June 9, 2016, SAFE promulgated the Circular on Reforming and Regulation of Administrative Policy on Settlement of Foreign Exchange of Capital Account, or SAFE Circular 16, which became effective on June 9, 2016. According to SAFE Circular 16, the foreign exchange capital of FIEs, foreign debt and funds raised through offshore listing may be settled on a discretionary basis, and can be settled at the banks. The proportion of such discretionary settlement is temporarily determined as 100%. The RMB converted from relevant foreign exchange will be kept in a designated account, and if a domestic enterprise needs to make further payment from such account, it still must provide supporting documents and go through the review process with the banks.

55

Furthermore, SAFE Circular 16 reiterates that the use of capital by domestic enterprises must adhere to the principles of authenticity and self-use within the business scope of enterprises. The foreign exchange income of capital account and RMB obtained by domestic enterprise from foreign exchange settlement must not be used (i) directly or indirectly for payment beyond the business scope of the enterprises or payment prohibited by relevant laws and regulations; (ii) directly or indirectly for investment in securities and investment in wealth management products except for principal-guaranteed bank wealth management products, unless otherwise provided by relevant laws and regulations; (iii) directly or indirectly for extending entrusted loans to non-affiliate enterprises, unless permitted by the scope of business; and/or (iv) for construction or purchase of real estate that is not for self-use, except for foreign-invested real estate enterprises.

Regulations Relating to Labor

Pursuant to the PRC Labor Law effective in 1995 and the PRC Labor Contract Law effective in 2008, a written labor contract is required when an employment relationship is established between an employer and an employee. Other labor-related regulations and rules of the PRC stipulate the maximum number of working hours per day and per week as well as the minimum wages. An employer is required to set up occupational safety and sanitation systems, implement the national occupational safety and sanitation rules and standards, educate employees on occupational safety and sanitation, prevent accidents at work and reduce occupational hazards.

In the PRC, workers dispatched by an employment agency are normally engaged in temporary, auxiliary or substitute work. Pursuant to the PRC Labor Contract Law, an employment agency is the employer for workers dispatched by it and shall perform an employer’s obligations toward them. The employment contract between the employment agency and the dispatched workers, and the placement agreement between the employment agency and the company that receives the dispatched workers shall be in writing. Furthermore, the company that accepts the dispatched workers shall be jointly and severally liable for any damage caused to the dispatched workers due to violation of the Labor Contract Law by the employment agencies arising from their contracts with dispatched workers. An employer is obligated to sign an indefinite term labor contract with an employee if the employer continues to employ the employee after two consecutive fixed-term labor contracts. The employer also has to pay compensation to the employee if the employer terminates an indefinite term labor contract. Except where the employer proposes to renew a labor contract by maintaining or raising the conditions of the labor contract and the employee is not agreeable to the renewal, an employer is required to compensate the employee when a definite term labor contract expires. Furthermore, under the Regulations on Paid Annual Leave for Employees issued by the State Council in December 2007 and effective as of January 2008, an employee who has served an employer for more than one year and less than ten years is entitled to a five-day paid vacation, those whose service period ranges from 10 to 20 years is entitled to a 10-day paid vacation, and those who has served for more than 20 years is entitled to a 15-day paid vacation. An employee who does not use such vacation time at the request of the employer shall be compensated at three times their normal salaries for each waived vacation day.

Pursuant to the Regulations on Occupational Injury Insurance effective in 2004, as amended in 2010, and the Interim Measures concerning the Maternity Insurance for Enterprise Employees effective in 1995, PRC companies must pay occupational injury insurance premiums and maternity insurance premiums for their employees. Pursuant to the Interim Regulations on the Collection and Payment of Social Insurance Premiums effective in 1999 and the Interim Measures concerning the Administration of the Registration of Social Insurance effective in 1999, basic pension insurance, medical insurance and unemployment insurance are collectively referred to as social insurance. Both PRC companies and their employees are required to contribute to the social insurance plans. Pursuant to the Regulations on the Administration of Housing Fund effective in 1999, as amended in 2002, PRC companies must register with applicable housing fund management centers and establish a special housing fund account in an entrusted bank. Both PRC companies and their employees are required to contribute to the housing funds.

56

According to the Social Insurance Law, an employer that fails to make social insurance contributions may be ordered to pay the required contributions within a stipulated deadline and be subject to a late fee. If the employer still fails to rectify the failure to make social insurance contributions within the stipulated deadline, it may be subject to a fine ranging from one to three times the amount overdue. According to the Regulations on Administration of Housing Fund, an enterprise that fails to make housing fund contributions may be ordered to rectify the noncompliance and pay the required contributions within a stipulated deadline; otherwise, an application may be made to a local court for compulsory enforcement.

Regulations Relating to Dividend Distribution

Wholly foreign-owned companies in the PRC may pay dividends only out of their accumulated profits after tax as determined in accordance with PRC accounting standards. Remittance of dividends by a wholly foreign-owned enterprise out of China is subject to examination by the banks designated by SAFE. Wholly foreign-owned companies may not pay dividends unless they set aside at least 10% of their respective accumulated profits after tax each year, if any, to fund certain reserve funds, until such time as the accumulative amount of such fund reaches 50% of the wholly foreign-owned company’s registered capital. These reserve funds are not distributable as cash dividends.

SAFE Regulations on Offshore Special Purpose Companies Held by PRC Residents or Citizens

SAFE Circular on Relevant Issues Relating to Domestic Resident’s Investment and Financing and Roundtrip Investment through Special Purpose Vehicles, or Circular 37, issued by SAFE and effective in July 2014, regulates foreign exchange matters in relation to the use of special purpose vehicles, or SPVs, by PRC residents or entities to seek offshore investment and financing and conduct round trip investment in China. Under Circular 37, a SPV refers to an offshore entity established or controlled, directly or indirectly, by PRC residents or entities for the purpose of seeking offshore financing or making offshore investment, using legitimate domestic or offshore assets or interests, while “round trip investment” refers to the direct investment in China by PRC residents or entities through SPVs, namely, establishing foreign-invested enterprises to obtain the ownership, control rights and management rights. Circular 37 requires that, before making contribution into an SPV, PRC residents or entities are required to complete foreign exchange registration with the SAFE or its local branch. SAFE Circular 37 further provides that option or share-based incentive tool holders of a non-listed SPV can exercise the options or share incentive tools to become a shareholder of such non-listed SPV, subject to registration with SAFE or its local branch.

PRC residents or entities who have contributed legitimate domestic or offshore interests or assets to SPVs but have yet to obtain SAFE registration before the implementation of the Circular 37 shall register their ownership interests or control in such SPVs with SAFE or its local branch. An amendment to the registration is required if there is a material change in the SPV registered, such as any change of basic information (including change of such PRC residents, name and operation term), increases or decreases in investment amount, transfers or exchanges of shares, or mergers or divisions. Failure to comply with the registration procedures set forth in Circular 37, or making misrepresentation on or failure to disclose controllers of foreign-invested enterprise that is established through round-trip investment, may result in restrictions on the foreign exchange activities of the relevant foreign-invested enterprises, including payment of dividends and other distributions, such as proceeds from any reduction in capital, share transfer or liquidation, to its offshore parent or affiliate, and the capital inflow from the offshore parent, and may also subject relevant PRC residents or entities to penalties under PRC foreign exchange administration regulations.

We have completed the foreign exchange registration of PRC resident shareholders for Mr. Yan Tang, Mr. Yong Li and Mr. Xiaoliang Lei with respect to our financings and share transfer.

M&A Rule and Overseas Listing

In August 2006, six PRC regulatory agencies, including China Securities Regulatory Commission, or CSRC, jointly adopted the Provisions Regarding Mergers and Acquisitions of Domestic Enterprises by Foreign Investors, or the M&A Rule, which became effective in September 2006. This M&A Rule purports to require, among other things, offshore SPVs, formed for listing purposes through acquisition of PRC domestic companies and controlled by PRC companies or individuals, to obtain the approval of the CSRC prior to publicly listing their securities on an overseas stock exchange. We believe that CSRC approval is not required in the context of our initial public offering as we are not a special purpose vehicle formed for listing purpose through acquisition of domestic companies that are controlled by our PRC individual shareholders, as we acquired contractual control rather than equity interests in our domestic affiliated entities.

57

However, we cannot assure you that the relevant PRC government agency, including the CSRC, would reach the same conclusion as we do. If the CSRC or other PRC regulatory agency subsequently determines that we need to obtain the CSRC’s approval for our initial public offering or if CSRC or any other PRC government authorities will promulgate any interpretation or implementing rules before our listing that would require CSRC or other governmental approvals for our initial public offering, we may face sanctions by the CSRC or other PRC regulatory agencies. In such event, these regulatory agencies may impose fines and penalties on our operations in the PRC, limit our operating privileges in the PRC, delay or restrict the repatriation of the proceeds from our initial public offering into the PRC, or take other actions that could have a material adverse effect on our business, financial condition, results of operations, and prospects, as well as the trading price of our ADSs.

SAFE Regulations on Employee Share Options

Pursuant to the Notice on Issues Concerning the Foreign Exchange Administration for Domestic Individuals Participating in Stock Incentive Plan of Overseas Publicly Listed Company, or Circular 7, issued by SAFE in February 2012, employees, directors, supervisors and other senior management participating in any stock incentive plan of an overseas publicly listed company who are PRC citizens or who are non-PRC citizens residing in China for a continuous period of not less than one year, subject to a few exceptions, are required to register with SAFE through a domestic qualified agent, which could be a PRC subsidiary of such overseas listed company, and complete certain other procedures. Failure to complete the SAFE registrations may subject them to fines and legal sanctions and may also limit our ability to contribute additional capital into our wholly foreign-owned subsidiaries in China and limit these subsidiaries’ ability to distribute dividends to us.

In addition, the State Administration for Taxation has issued certain circulars concerning employee share options or restricted shares. Under these circulars, the employees working in the PRC who exercise share options or are granted restricted shares will be subject to PRC individual income tax. The PRC subsidiaries of such overseas listed company have obligations to file documents related to employee share options or restricted shares with relevant tax authorities and to withhold individual income taxes of those employees who exercise their share options. If the employees fail to pay or the PRC subsidiaries fail to withhold their income taxes according to relevant laws and regulations, the PRC subsidiaries may face sanctions imposed by the tax authorities or other PRC government authorities. These registrations and filings are a matter of foreign exchange control and tax procedure and the grant of share incentive awards to employees is not subject to the government’s discretionary approval. Compliance with PRC regulations on employee incentive plans has not had, and we believe will not in the future have, any material adverse effect on the implementation of our 2012 Plan and 2014 Plan.

The following diagram illustrates our corporate structure, including our subsidiaries, consolidated affiliated entity and its subsidiaries as of the date of this annual report.

Contractual Arrangements with Our Consolidated Affiliated Entities and Their Respective Shareholders

PRC laws and regulations place certain restrictions on foreign investment in and ownership of internet-based businesses. Accordingly, we conduct our operations in China principally through Beijing Momo and its subsidiaries, Tantan Culture, Hainan Miaoka, Hainan Yilingliuer, Beijing Fancy Reader and Tianjin QOOL Media. Beijing Momo IT entered into contractual arrangements with Beijing Momo, Beijing Fancy Reader and their respective shareholders. Beijing Yiliulinger, a wholly owned subsidiary of Beijing Momo IT, entered into contractual arrangements with Hainan Miaoka, Hainan Yilingliuer and their respective shareholders.

The contractual arrangements allow us to:

As a result of these contractual arrangements, we are the primary beneficiary of our consolidated affiliated entities and their subsidiaries, and, therefore, have consolidated the financial results of our consolidated affiliated entities and their subsidiaries in our consolidated financial statements in accordance with U.S. GAAP.

The following is a summary of the currently effective contractual arrangements by and among our wholly-owned subsidiary, Beijing Momo IT, Beijing Momo and the shareholders of Beijing Momo. We also entered into contractual arrangements with Tantan Culture, Hainan Miaoka, Hainan Yilingliuer, Beijing Fancy Reader and Tianjin QOOL Media.

Beijing Momo IT is entitled to any dividends or other interests declared by Beijing Momo and the shareholders of Beijing Momo have agreed to promptly transfer such dividends or other interests to Beijing Momo IT. These agreements have an initial term of ten years from the date of execution, and may be extended at the discretion of Beijing Momo IT. Beijing Momo IT may terminate this agreement at any time by giving a prior written notice to Beijing Momo and its shareholders. Neither Beijing Momo nor its shareholders may terminate this agreement.

60

Exclusive call option agreements. Under the exclusive call option agreements between Beijing Momo IT, Beijing Momo and each of the shareholders of Beijing Momo entered into on April 18, 2012, and amended and restated on April 18, 2014, each of the shareholders of Beijing Momo irrevocably granted Beijing Momo IT an exclusive option to purchase, to the extent permitted under PRC law, all or part of their equity interests in Beijing Momo for a nominal price of RMB10 or the lowest price permitted under PRC law. In addition, Beijing Momo irrevocably granted Beijing Momo IT an exclusive and irrevocable option to purchase any or all of the assets owned by Beijing Momo at the lowest price permitted under PRC law. Without Beijing Momo IT’s prior written consent, Beijing Momo and its shareholders will not sell, transfer, mortgage or otherwise dispose of Beijing Momo’s material assets, legal or beneficial interests or revenues of more than RMB500,000, or allow an encumbrance on any interest in Beijing Momo. These agreements will remain effective until all equity interests held in Beijing Momo by its shareholders are transferred or assigned to Beijing Momo IT.

Equity interest pledge agreements. Under the equity interest pledge agreements between Beijing Momo IT, Beijing Momo and the shareholders of Beijing Momo entered into on April 18, 2012, and amended and restated on April 18, 2014, the shareholders of Beijing Momo pledged all of their equity interests in Beijing Momo (including any equity interest subsequently acquired) to Beijing Momo IT to guarantee the performance by Beijing Momo and its shareholders of their respective obligations under the contractual arrangements, including the payments due to Beijing Momo IT for services provided. If Beijing Momo or any of its shareholders breach their obligations under these contractual arrangements, Beijing Momo IT, as the pledgee, will be entitled to certain rights and remedies, including priority in receiving the proceeds from the auction or disposal of the pledged equity interests in Beijing Momo. Beijing Momo IT has the right to receive dividends generated by the pledged equity interests during the term of the pledge. The pledge becomes effective on the date when the pledge of equity interests contemplated under the agreement is registered with the relevant local administration for industry and commerce and will remain binding until Beijing Momo and its shareholders discharge all their obligations under the contractual arrangements. We have registered the equity interest pledge agreements with Chaoyang Branch of Beijing Administration for Industry and Commerce in Beijing.

Powers of attorney. Pursuant to the powers of attorney entered into on April 18, 2012 and amended and restated on April 18, 2014, each shareholder of Beijing Momo irrevocably appointed Beijing Momo IT as their attorney-in-fact to act for all matters pertaining to Beijing Momo and to exercise all of their rights as shareholders of Beijing Momo, including attending shareholders’ meetings and designating and appointing legal representatives, directors and senior management members of Beijing Momo. Beijing Momo IT may authorize or assign its rights under this appointment to any other person or entity at its sole discretion without prior notice to or prior consent from the shareholders of Beijing Momo. Each power of attorney remains in force until the shareholder ceases to hold any equity interest in Beijing Momo.

Spousal consent letters. Under the spousal consent letters, each spouse of the married shareholders of Beijing Momo unconditionally and irrevocably agreed that the equity interest in Beijing Momo held by and registered in the name of their spouse will be disposed of pursuant to the equity interest pledge agreement, the exclusive call option agreement, and the power of attorney. Each spouse agreed not to assert any rights over the equity interest in Beijing Momo held by their spouse. In addition, in the event that the spouses obtain any equity interest in Beijing Momo held by their spouse for any reason, they agreed to be bound by the contractual arrangements.

Exclusive cooperation agreements. Beijing Momo IT entered into an exclusive cooperation agreement and a supplemental agreement with Beijing Momo and Chengdu Momo, respectively, on August 31, 2014 to supersede the exclusive technology consulting and management services agreement signed in April 2012 between Beijing Momo IT and Beijing Momo. In May 2016 and December 2017, Beijing Momo IT entered into an exclusive cooperation agreement and a supplemental agreement with Tianjin Heer and Loudi Momo, respectively. Pursuant to the aforesaid exclusive cooperation agreements, each as amended, Beijing Momo IT has the exclusive right to provide, among other things, licenses, copyrights, technical and non-technical services to Beijing Momo, Chengdu Momo, Tianjin Heer and Loudi Momo and receive service fees and license fees as consideration. Beijing Momo, Chengdu Momo, Tianjin Heer and Loudi Momo will maintain a pre-determined level of operating profit and remit any excess operating profit to Beijing Momo IT as consideration for the licenses, copyrights, technical and non-technical services provided by Beijing Momo IT. Each agreement has an initial term of ten years from the date of execution, and may be extended at the sole discretion of Beijing Momo IT. Beijing Momo IT may terminate the agreement at any time with a 30-day notice to Beijing Momo, Chengdu Momo, Tianjin Heer and Loudi Momo, as applicable, but Beijing Momo, Chengdu Momo, Tianjin Heer and Loudi Momo may not terminate the agreement.

In the opinion of Han Kun Law Offices, our PRC counsel:

However, there are substantial uncertainties regarding the interpretation and application of current and future PRC laws, regulations and rules. Accordingly, the PRC regulatory authorities may in the future take a view that is contrary to the above opinion of our PRC counsel. If the PRC government finds that the agreements that establish the structure for operating our business do not comply with PRC government restrictions on foreign investment in our businesses, we could be subject to severe penalties, including being prohibited from continuing operations. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Corporate Structure—If the PRC government finds that the agreements that establish the structure for operating our businesses in China do not comply with PRC regulations on foreign investment in internet and other related businesses, or if these regulations or their interpretation change in the future, we could be subject to severe penalties or be forced to relinquish our interests in those operations,” and “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China—Uncertainties in the interpretation and enforcement of PRC laws and regulations could limit the legal protections available to you and us.”

Beijing Momo IT also entered into an exclusive cooperation agreement and a supplemental agreement with Chengdu Momo, Tianjin Heer and Loudi Momo on August 31, 2014, May 1, 2016 and December 1, 2017, respectively, which agreements are substantially similar to the ones entered into between Beijing Momo IT and Beijing Momo described above.

Our headquarters and our principal service development facilities are located in Beijing. We leased an aggregate of approximately 38,729 square meters of office space in Beijing, Chengdu, Tianjin, Shanghai, Guangzhou, Kuala Lumpur and San Jose as of March 31, 2019. These leases vary in duration from seven months to five years.

The servers that we use to provide our services are primarily maintained at various third-party internet data centers in Beijing.

None.

Major Factors Affecting Our Results of Operations

User Growth. Our revenues are driven by the number of our paying users for the various services we offer to users, including live video service, value-added service, online games and other services. For 2018, we generated our revenues primarily from live video service, value-added service, mobile marketing and mobile games. The number of paying users for our live video service and value-added services on Momo application, without double counting the overlap, increased from 8.0 million in 2016 to 13.7 million in 2017 and further to 17.7 million in 2018. The number of paying users on Tantan application was 4.1 million from June 2018 to December 2018. The number of our paying users is affected by the growth in our active user base, our ability to convert a greater portion of our users into paying users, and strategies we pursue to achieve active user growth at reasonable costs and expenses.

Momo MAUs increased from 81.1 million in December 2016 to 99.1 million in December 2017 and further to 113.3 million in December 2018.

User Engagement. Changes in user engagement could affect our revenues and financial results. Active user engagement powered by diverse functionalities and rich contents is essential for our ability to generate revenues from the various services we offer to users, including our live video business, value-added service, among others.

Monetization. We started monetization in the second half of 2013 by introducing mobile games and membership services to our users, and we are continuing to refine the ways to monetize our service offerings without adversely affecting user experience. In 2015, we started to offer premium membership services, in-feed marketing solutions and live video service and in the fourth quarter of 2016, we launched a virtual gift service which allows our users to purchase and send virtual gifts to other users outside of live video service, which all contributed to our revenue growth. In 2018, we produced a television program. Our live video service currently contributes to the largest share of our revenues, generating 79.9% of our net revenues in 2018. For mobile games, we started to scale back from licensed mobile game services and instead focus on self-developed games in early 2017 in order to better align the games offered on our platform with the positioning and strength of Momo as a location-based social platform. Our future revenue growth will be affected by our ability to effectively execute our monetization strategies.

Investment in Technology Infrastructure and Talent. Our technology infrastructure is critical for us to retain and attract users, customers and platform partners. We must continue to upgrade and expand our technology infrastructure to keep pace with the growth of our business, to develop new features and services for our platform and to further enhance our big data analytical capabilities.

Our employee headcount has increased significantly as our business has grown and we expect this trend to continue for the foreseeable future. The number of our employees increased from 924 as of December 31, 2016 to 1,244 as of December 31, 2017 and further to 2,147 as of December 31, 2018. There is strong demand in China’s internet industry for talented and experienced personnel from fast-growing, large-scale social networking platforms. We must recruit, retain and motivate talented employees while controlling our personnel-related expenses, including share-based compensation expenses.

Taxation

Cayman Islands

We are registered by way of continuation into the Cayman Islands. Under the current law of the Cayman Islands, we are not subject to income or capital gains tax in the Cayman Islands. In addition, our payment of dividends to our shareholders, if any, is not subject to withholding tax in the Cayman Islands.

British Virgin Islands

Our subsidiaries incorporated in the British Virgin Islands are tax-exempted companies.

63

United States

Our subsidiaries incorporated in the United States are subject to state income tax and federal income tax. In December 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as the Tax Cuts and Jobs Act, or the Tax Act. The Tax Act makes broad and complex changes to the U.S. tax code including, but not limited to, (i) reducing the U.S. federal corporate tax rate, (ii) requiring a one-time transition tax on certain un-repatriated earnings of foreign subsidiaries that are payable over eight years, and (iii) bonus depreciation that will allow for full expensing of qualified property. The impact of the Tax Act is not material to our operation and resulted in a decrease in income tax rate from 35% before January 1, 2018 to 21% after January 1, 2018 for tax and income earned as determined in accordance with the relevant tax rules and regulations. As our U.S. subsidiaries did not have any taxable income, no income tax expense was provided for in the year ended December 31, 2018.

Hong Kong

Our subsidiaries domiciled in Hong Kong are subject to a two-tiered income tax rate for taxable income earned in Hong Kong effectively since April 1, 2018. The first 2 million Hong Kong dollars of profits earned by the company are subject to be taxed at an income tax rate of 8.25%, while the remaining profits will continue to be taxed at the existing tax rate, 16.5%. In 2016, 2017 and 2018, no provision for Hong Kong tax was made in our consolidated financial statements, as our Hong Kong subsidiaries had not generated any assessable income.

People’s Republic of China

Pursuant to the EIT Law, which became effective on January 1, 2008, foreign-invested enterprises and domestic companies are subject to enterprise income tax at a uniform rate of 25%. In August 2014, Beijing Momo IT was qualified as a software enterprise. As such, Beijing Momo IT will be exempt from income taxes for two years beginning in its first profitable year (i.e. 2015 and 2016) followed by a tax rate of 12.5% for the succeeding three years (i.e. from 2017 to 2019). Chengdu Momo was qualified as a Western China Development Enterprise and the income tax rate was 15% in 2015, 2016 and 2017. According to No. 23 announcement of the State Administration of Taxation of PRC in April 2018, Chengdu Momo was no longer required to submit the preferential tax rate application to the tax authority, but only required to keep the relevant materials for future tax inspection instead. Based on the historically experience, we believe Chengdu Momo will most likely continue to be qualified as a Western China Development Enterprise and accordingly be entitled to a preferential income tax rate of 15%. Therefore, we applied 15% to determine the tax liabilities for Chengdu Momo in the year ended December 31, 2018. Santi Cloud Union was qualified as a high and new technology enterprise in 2018, and was therefore subject to a preferential enterprise income tax rate of 15% from 2018 through 2020. The other entities incorporated in the PRC were subject to an enterprise income tax at a rate of 25%.

We have recognized income tax expense of RMB34.6 million, RMB445.0 million and RMB699.6 million for the years ended December 31, 2016, 2017 and 2018, respectively.

Effective January 1, 2012, the PRC Ministry of Finance and the State Administration of Taxation launched a Business Tax to Value-Added Tax Transformation Pilot Program, or the VAT Pilot Program, which imposes VAT in lieu of business tax for certain “modern service industries” in certain regions and eventually expands to nation-wide in 2013. According to the implementation circulars released by the Ministry of Finance and the State Administration of Taxation on the VAT Pilot Program, the “modern service industries” include research, development and technology services, information technology services, cultural innovation services, logistics support, lease of corporeal properties, attestation and consulting services. Effective from May 1, 2016, PRC tax authorities collect VAT in lieu of business tax in all regions and industries. All of our entities were subject to VAT at rate of 6% for services provided and 17% for goods sold which are not listed in Article 2 Sub-article 2 of the Provisional Regulations on Value Added Tax of the PRC as of December 31, 2018. With the imposition of VAT in lieu of business tax, our revenues are subject to VAT payable on goods sold or taxable services provided by a general VAT taxpayer for a taxable period, which is the net balance of the output VAT for the period after crediting the input VAT for the period. Hence, the amount of VAT payable does not result directly from output VAT generated from goods sold or taxable services provided. In addition, according to the prevailing PRC tax regulations, the input VAT caused by purchasing goods or services can be credited against output VAT by general taxpayer when calculating VAT payable, provided that the general taxpayer obtained and verified the relevant VAT special invoices corresponding to the cost or expenditures within a defined time period. All of our entities have obtained the VAT special invoices as the deduction vouchers, and therefore, we have adopted the net presentation of VAT.

64

Pursuant to applicable PRC laws and regulations, arrangements and transactions among related parties may be subject to audit or challenge by the PRC tax authorities. We may be subject to adverse tax consequences and our consolidated results of operations may be adversely affected if the PRC tax authorities determine that the contractual arrangements among our PRC subsidiary, Beijing Momo and its shareholders or its subsidiaries are not on an arm’s length basis and therefore constitute favorable transfer pricing. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Corporate Structure—Contractual arrangements we have entered into with our consolidated affiliated entities may be subject to scrutiny by the PRC tax authorities. A finding that we owe additional taxes could significantly reduce our consolidated net income and the value of your investment.”

Reorganization of Operating Segments

In 2018, we reorganized our operating segments from a single operating segment into three operating segments, namely Momo’ service lines, Tantan’s service lines and QOOL’s service line. The change in operating segments reflects our acquisition of Tantan and QOOL’s new entertainment business. Our chief operating decision maker assesses the performance of our company and makes decisions in respect of the allocation of our resources by analyzing the operating results of these operating segments separately. Prior to our acquisition of Tantan, Tantan’s financial information was not consolidated to ours. Therefore, Tantan’s service lines did not have comparable financial information in 2016 and 2017. QOOL started its entertainment business such as the TV content production in 2018, so its comparable financial information in 2016 and 2017 accounted insignificant portion to our consolidated financial statements.

Results of Operations

The following table sets forth a summary of our consolidated results of operations for the periods indicated, both in absolute amounts and as percentages of our total net revenues. This information should be read together with our consolidated financial statements and related notes included elsewhere in this annual report. The results of operations in any period are not necessarily indicative of the results that may be expected for any future period.

Comparison of the Years Ended December 31, 2016, 2017 and 2018

Net revenues

We currently generate revenues primarily from live video service, value-added service, mobile marketing services, mobile games, and other services. Revenues from live video service, value-added service and other services are presented net of value-added taxes and surcharges. Mobile marketing services are presented net of agency rebates, value-added taxes and surcharges. Mobile games revenues include revenues generated from mobile games developed by third-party game developers and from self-developed mobile games. Mobile games revenues generated by third-party game developers are presented net of revenue sharing with game developers, commission fees made to third-party application stores and other payment channels, value-added taxes and surcharges. Mobile games revenues derived from self-developed games are recorded on a gross basis. Net revenues increased from RMB3,707.4 million in 2016 to RMB8,886.4 million in 2017, and further to RMB13,408.4 million (US$1,950.2 million) in 2018, primarily driven by the significant increase in net revenues from live video service and value-added service.

65

Live video service

We started to offer live video services on our Momo platform in September 2015. We generate revenues when users purchase and send in-show virtual items to broadcasters. Initially, the service adopted an online live concert format whereby we invited certain talented performers to put on live music shows in a professional studio environment. Such shows were broadcasted live in one to four sessions on a daily basis and at pre-announced times. In the fourth quarter of 2015, we opened more live channels in order to enable more performers to put on talent shows to entertain and interact with their audience. Until April 2016, we only offered the service to a limited number of talented performers pre-selected carefully by us. In April 2016, we opened up the service to all the users of our platform so that each one of them can become a broadcaster if they wish. Our live video service revenues further increased from RMB2,534.6 million in 2016 to RMB7,429.9 million in 2017 and RMB10,709.5 million (US$1,557.6 million) in 2018, primarily due to the increase in paying users and the increase in the average revenues per paying user resulting from our continued effort to enhance content attractiveness, optimize product features, improve user experience, and introduce interactive streaming channels to grow our user base and develop their willingness to pay for live video service.

Value-added service

Value-added service primarily comprises membership subscription and virtual gift service. Both Momo and Tantan users can become members by paying membership fees per contract period, which ranges from one month to one year. Both Momo and Tantan members are entitled to additional functionalities and privileges on Momo and Tantan mobile applications, respectively. We started to offer virtual gift service on Momo platform in the fourth quarter of 2016 to enhance users’ interaction and social networking with each other. We start to report revenues from membership subscription and virtual gift services together as value-added services since 2016.

2018 compared to 2017. Revenues from our value-added service increased 170.6% to RMB1,883.2 million (US$273.9 million) in 2018 from RMB695.8 million in 2017, primarily attributable to the continuous growth of the virtual gift business on Momo mobile application driven by more paying social scenarios introduced to enhance the social experience of Momo users, and to a lesser extent, the contribution of Tantan’s membership subscription revenue consolidated since June 2018.

2017 compared to 2016. Revenues from our value-added service increased 54.7% to RMB695.8 million in 2017 from RMB449.8 million in 2016, primarily due to the increase in the number of paying users as we offered virtual gift service to enrich communication experience among users.

Mobile marketing services

Our mobile marketing services currently include in-feed marketing solutions powered by a proprietary self-serve advertising system, brand-oriented display ads, and advertising services provided through third-party partnerships.

2018 compared to 2017. Mobile marketing services revenues decreased 2.7% to RMB500.3 million (US$72.8 million) in 2018 from RMB514.3 million in 2017, primarily due to the decrease of our advertising and marketing customer demands.

2017 compared to 2016. Mobile marketing services revenues increased 16.4% to RMB514.3 million in 2017 from RMB441.6 million in 2016, primarily due to an increase in revenues from our brand-oriented display ads as a result of better sell-through of our existing advertisement inventories as we provided new ad format and marketing solutions to our clients.

Mobile games

As of December 31, 2018, we had three types of mobile game services, namely non-exclusive licensed mobile game services, exclusive licensed mobile game services and self-developed mobile game services. We offer our mobile game platform for mobile games developed by third-party game developers non-exclusively or exclusively, and we share user payments with such game developers. In addition to licensed mobile games, we also operate self-developed mobile games on our mobile game platform. As of December 31, 2018, we operated nine non-exclusive licensed games, two exclusive licensed games and four self-developed games. We expect the number of games operated on our platform to fluctuate quarter by quarter. Our revenues from mobile games depend on the number of paying users, which ultimately is determined by our ability to select and offer engaging games tailored to our platform and our user profiles.

66

2018 compared to 2017. Our mobile games revenues decreased 46.0% to RMB130.4 million (US$19.0 million) in 2018 from RMB241.4 million in 2017, primarily due to the decrease in our paying users.

2017 compared to 2016. Our mobile games revenues slightly increased 2.2% to RMB241.4 million in 2017 from RMB236.2 million in 2016, primarily due to an increase in revenue from a new self-developed game which we launched in the second quarter of 2016 and for which we recognized revenue on a gross basis, partially offset by a decrease in paying users and revenue from other existing licensed games as we have recently started to scale back from licensed mobile game services and instead focus on self-developed games.

Other services

Our other services include television content production service, paid emoticons, gift mall sales and certain quasi-lucky draw game service. We ceased to provide gift mall services and paid emoticons in November 2016 and the quasi-lucky draw game service in January 2017, due to the adjustment of our strategic priorities.

2018 compared to 2017. Other services revenues increased to RMB185.1 million (US$26.9 million) in 2018 from RMB5.0 million in 2017, primarily attributable to revenues of RMB169.6 million (US$24.7 million) generated from advertisement revenue sharing upon broadcasting of one produced television program.

2017 compared to 2016. Other services revenues decreased 88.9% to RMB5.0 million in 2017 from RMB45.1 million in 2016, primarily due to the winding down of the quasi-lucky draw game service and paid emoticons services in 2017.

Cost and expenses

Cost of revenues

Cost of revenues consists primarily of costs associated with the operation and maintenance of our platform, including revenue sharing, production costs in connection with television content, commission fees, bandwidth costs, labor costs, depreciation and other costs.

Revenue sharing primarily includes payments to broadcasters and talent agencies for our live video service, virtual gift recipients for our virtual gift service, and self-developed mobile game subcontractors. Commission fees are payments made to third-party application stores and other payment channels for distributing our live video service, value-added service, self-developed mobile games and our mobile marketing services. Users can make payments for such services through third-party application stores and other payment channels. These third-party application stores and other payment channels typically charge a handling fee for their services. Bandwidth costs, including internet data center and content delivery network fees, consist of fees that we pay to telecommunication carriers and other service providers for telecommunication services, hosting our servers at their internet data centers, and providing content and application delivery services. Labor costs consist of salaries and benefits, including share-based compensation expenses, for our employees involved in the operation of our platform. Depreciation mainly consists of depreciation cost on our servers, computers and other equipment. Other costs mainly consist of production costs in connection with our television content. We expect our cost of revenues to increase in the future as we continue to expand our services, as well as to enhance the capability and reliability of our infrastructure to support user growth and increased activity on our platform.

The following table sets forth the components of our cost of revenues by amounts and percentages of our total cost of revenues for the periods presented:

67

2018 compared to 2017. Our cost of revenues increased from RMB4,373.4 million in 2017 to RMB7,182.9 million (US$1,044.7 million) in 2018. The increase was primarily due to a RMB2,178.3 million increase in revenue sharing from an increase in live video service revenue and virtual gift service revenue, a RMB429.2 million increase in the production costs in connection with television content, a RMB81.1 million increase in depreciation and amortization costs, a RMB67.7 million increase in bandwidth costs due to a larger scale of live video services, value-added services, social games as well as other video- and audio-based interactive functions, a RMB67.4 million increase in labor costs resulting from an increase in the number of employees involved in the operations of our Momo and Tantan platforms, partially offset by a RMB31.2 million decrease in commission fees paid to payment channels due to the decreased average commission rate charged by those channels.

2017 compared to 2016. Our cost of revenues increased from RMB1,619.3 million in 2016 to RMB4,373.4 million in 2017, primarily due to a RMB2,354.9 million increase in revenue sharing resulting from an increase in live video service revenue and virtual gift service revenue, a RMB165.2 million increase in commission fees resulting from an increase in fees to payment channels due to a higher volume of cash collection through such channels, a RMB120.1 million increase in bandwidth costs due to larger scale of live video service, short video services, social games as well as other video- and audio-based interactive functions, a RMB38.9 million increase in labor costs resulting from an increase in the number of employees involved in the operation of our platform and a RMB20.1 million increase in depreciation and amortization costs, which were driven by additional services and functions introduced on the Momo platform.

Research and development expenses

Research and development expenses consist primarily of salaries and benefits, including share-based compensation expenses, for research and development personnel and rental expenses associated with research and development activities. Expenditures incurred during the research phase are expensed as incurred. We expect our research and development expenses to increase as we expand our research and development team to develop new features and services for our platform and to further enhance our big data analytical capabilities.

2018 compared to 2017. Our research and development expenses increased by 119.7% from RMB346.1 million in 2017 to RMB760.6 million (US$110.6 million) in 2018. This increase was primarily due to a RMB361.3 million increase in salaries and benefits for research and development personnel. Our research and development headcount increased from 552 as of December 31, 2017 to 1,172 as of December 31, 2018.

2017 compared to 2016. Our research and development expenses increased by 65.9% from RMB208.6 million in 2016 to RMB346.1 million in 2017. This increase was primarily due to a RMB125.5 million increase in salaries and benefits for research and development personnel. Our research and development headcount increased from 367 as of December 31, 2016 to 552 as of December 31, 2017.

Sales and marketing expenses

Sales and marketing expenses consist primarily of general marketing and promotional expenses, as well as salaries and benefits, including share-based compensation expenses, for our sales and marketing personnel. We expect our sales and marketing expenses to increase as we plan to enhance our brand awareness, attract new users and promote our new services.

2018 compared to 2017. Our sales and marketing expenses increased by 23.5% from RMB1,467.4 million in 2017 to RMB1,812.3 million (US$263.6 million) in 2018, primarily due to a RMB200.1 million increased marketing and promotional expenses to attract users and promote our live video services, a RMB91.5 million increase in salaries and other benefits for our sales and marketing personnel, and a RMB39.6 million increase in amortization expenses related to intangible assets from business acquisitions.

2017 compared to 2016. Our sales and marketing expenses increased by 126.7% from RMB647.2 million in 2016 to RMB1,467.4 million in 2017, primarily due to a RMB668.5 million increased expenses as we stepped up marketing efforts to enhance our brand awareness, attract users and promote our live video service and a RMB91.5 million increase in salaries and other benefits for our sales and marketing personnel.

68

General and administrative expenses

General and administrative expenses consist primarily of salaries and other benefits, including share-based compensation expense, professional fees and rental expenses. We expect our general and administrative expenses to increase as our business grows.

2018 compared to 2017. Our general and administrative expenses increased from RMB422.0 million in 2017 to RMB640.0 million (US$93.1 million) in 2018. This increase was primarily due to an increase in personnel related costs, including share-based compensation expenses as a result of our rapidly expanding talent pool.

2017 compared to 2016. Our general and administrative expenses increased from RMB259.7 million in 2016 to RMB422.0 million in 2017. This increase was primarily due to the increase in personnel related salaries and other benefits, including share-based compensation expenses, as a result of our rapidly expanding talent pool and the increase of auditing and other professional service expenses.

Net income

2018 compared to 2017. Primarily as a result of the foregoing, our net income increased from RMB2,144.5 million in 2017 to RMB2,788.5 million (US$405.6 million) in 2018.

2017 compared to 2016. Primarily as a result of the foregoing, our net income increased from RMB979.0 million in 2016 to RMB2,144.5 million in 2017.

The following table sets forth our operating costs and expenses by segment and year-over-year change rate for the periods indicated:

69

Momo. Operating costs and expenses of Momo mainly consist of revenue sharing, salaries and benefits, marketing and promotion expenses, bandwidth costs, professional fees and commission fees.

Cost of revenues. The cost of revenues of Momo in 2018 were RMB6,573.0 million (US$956.0 million) representing a 50% year over year increase, primarily due to an increase in revenue sharing from an increase in live video service revenue and virtual gift service revenue, an increase in labor costs resulting from an increase in the number of employees, an increase in bandwidth costs due to a larger scale of live video services, value-added services, social games as well as other video- and audio-based interactive functions, partially offset by a decrease in commission fees paid to payment channels due to decreased average commission rate charged by those channels.

Research and development expense. The research and development expenses of Momo increased by 77% from RMB346.1 million in 2017 to RMB614.1 million (US$89.3 million) in 2018, primarily due to an increase in salaries and benefits for research and development personnel.

Sales and marketing expenses. The sales and marketing expenses of Momo decreased by 13% from RMB1,457.7 million in 2017 to RMB1,269.5 million (US$ 184.6 million ) in 2018, primarily due to saving in marketing and promotional expenses.

70

Inflation

Since our inception, inflation in China has not materially impacted our results of operations. According to the National Bureau of Statistics of China, the year-over-year percent changes in the consumer price index for December 2016, 2017 and 2018 were increases of 2.1%, 1.8% and 1.9%, respectively. Although we have not in the past been materially affected by inflation since our inception, we can provide no assurance that we will not be affected in the future by higher rates of inflation in China.

Critical Accounting Policies

We prepare our financial statements in conformity with U.S. GAAP, which requires us to make estimates and assumptions that affect our reporting of, among other things, assets and liabilities, revenues and expenses and contingent assets and liabilities. We continually evaluate these estimates and assumptions based on the most recently available information, our own historical experience and other factors that we believe to be relevant under the circumstances. Since our financial reporting process inherently relies on the use of estimates and assumptions, our actual results could differ from what we expect. This is especially true with some accounting policies that require higher degrees of judgment than others in their application. We consider the policies discussed below to be critical to an understanding of our audited consolidated financial statements because they involve the greatest reliance on our management’s judgment.

Revenue Recognition

Adoption of Accounting Standard Codification, or the ASC, “Revenue from Contracts with Customers”

In May 2014, the Financial Accounting Standards Board, or the FASB, issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), or the Topic 606, as modified by subsequently issued ASUs 2015-14, 2016-08, 2016-10, 2016-12 and 2016-20 (collectively ASU 2014-09).

On January 1, 2018, we adopted Topic 606 by applying the modified retrospective method to contracts that were not completed as of January 1, 2018. Results for the reporting periods beginning after January 1, 2018 are presented under Topic 606 while prior period amounts are not adjusted and continue to be reported in accordance with our historical accounting under Topic 605. The adoption of Topic 606 did not have a material impact on the our consolidated results of operations, financial position or cash flows but resulted in additional disclosures regarding the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

We principally derive our revenues from live video service, value-added service, mobile marketing services, mobile games, and other services. We recognize revenue when control of the promised goods or services are transferred to the customers, in an amount that reflects the consideration that expects to receive in exchange for those goods or services. We applied the five steps method outlined in Topic 606 to all revenue streams. In addition, the standard requires disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers.

For the years ended December 31, 2016, 2017 and 2018, all the revenue for the periods was recognized from contracts with customers. Our revenue is reported net of discount, value added tax and surcharges.

Live video service. We principally provide live video service whereby users can enjoy live performance and interact with the broadcasters for free during the performance. Broadcasters can either host the performance on their own or join a talent agency. We generate revenue from sales of virtual items to our users. We design, create and offer various virtual items for sales to users with pre-determined stand-alone selling price, which if users chose to, can be purchased and presented to the broadcasters to show their support during their live video performance. We have a recharge system for users to purchase our virtual currency that can then be used to purchase virtual items on our platform. Users can recharge via various third-party application stores and other payment channels. Virtual currency is non-refundable and does not have any expiration date. Based on the turnover history of virtual currency, we determined that the virtual currency was often consumed soon after it was purchased and accordingly, we concluded that any breakage would be insignificant. Unconsumed virtual currency is recorded as deferred revenue. Virtual currency used to purchase virtual items is recognized as revenue according to the prescribed revenue recognition policies of virtual items addressed below unless otherwise stated. All virtual items are non-refundable, consumed at a point-in-time and expire in a few days after the purchase. Under arrangements entered into with broadcasters and talent agencies, we share a portion of the revenues derived from the sales of virtual items with them ("Revenue Sharing").

We have evaluated and determined that we are the principal and we view the users to be our customers. Specifically, we control the virtual items before they are transferred to users. Our control is evidenced by our sole ability to monetize the virtual items before they are transferred to users, and is further supported by us being primarily responsible to the users for the delivery of the virtual items as well as having full discretion in establishing pricing for the virtual items. Accordingly, we report our live video service revenues on a gross basis with amounts billed to users for the virtual items recorded as revenues and the Revenue Sharing paid to broadcasters and talent agencies recorded as cost of revenues. Sales proceeds are initially recorded as deferred revenue and recognized as revenue based on the consumption of the virtual items. We have determined that the virtual items represent one performance obligation in the live video service. Revenue related to each of the virtual item is recognized at the point in time when the virtual item is transferred directly to the relevant broadcasters and consumed by them. Although some virtual items have expiry dates, we consider that the impact of breakage for the virtual items is insignificant as historical data shows that virtual items are consumed shortly after they are released to users and the forfeiture rate remains relatively low for the periods presented. We do not have further performance obligations to the users after the virtual items are consumed.

Users also have the right to purchase various combinations of virtual items in the live video, which are generally capable of being distinct. Specifically, we enter into certain contracts with our users where virtual item coupons are granted to users simultaneously with a purchase of a virtual item. The virtual item coupons can be used by the users to exchange for free virtual items in the future. Such virtual item coupons typically expire a few days after being granted. We have determined that the virtual item coupons represent a material right under Topic 606 which is recognized as a separate performance obligation at the outset of the arrangement. Judgment is required to determine the stand-alone selling price for each distinct virtual item and virtual item coupons. We allocate the consideration to each distinct virtual item and virtual item coupon based on their relative stand-alone selling prices. In instances where stand-alone selling price is not directly observable as we do not sell the virtual items separately, we determine the stand-alone selling price based on pricing strategies, market factors and strategic objectives. We recognize revenue for each of the distinct virtual item in accordance with the revenue recognition method discussed above unless otherwise stated. Revenue for the virtual item coupons are recognized when the virtual items purchased with the virtual item coupons are consumed. Although virtual item coupons have expiry dates, we consider that the impact of breakage for the virtual item coupons is insignificant as historical data shows that virtual item coupons are consumed shortly after they are released to users and the forfeiture rate remains relatively low for the periods presented.

We do not provide any right of return and do not provide any other credit or incentive to our users.

Value-added Service. Value-added services revenues mainly include membership subscription revenue and virtual gift service revenue. Membership subscription is a service package which enables members to enjoy additional functions and privileges. The contract period for the membership subscription ranges from one month to one year. All membership subscription is nonrefundable. We have determined that membership subscription services represent one performance obligation. We collect membership subscription in advance and record it as deferred revenue. Revenue is recognized ratably over the contract period as the membership subscription services are delivered.

72

We launched virtual gift service in 2016 to enhance users’ experience of interaction and social networking with each other. Users purchase virtual items and send the virtual items to other users. We share a portion of the revenues derived from the sales of virtual items with the recipient of the virtual item. All virtual items are nonrefundable, consumed point-in-time and expired in a few days after the purchase. Although some virtual items have expiry dates, we consider that the impact of breakage for the virtual items is insignificant as historical data shows that the virtual items are consumed shortly after they are release to users, and the forfeiture rate remains relatively low for the periods presented. We collect the cash from the purchase of virtual items and recognized the sales of virtual items when the performance obligation is satisfied. We have determined that we have one single performance obligation which is the display of the virtual items for the users who purchase them. Revenues derived from the sale of virtual items are recorded on a gross basis as we have determined that we are the principal in providing the virtual gift services for the same reasons outlined in the revenue recognition policy for the live video services. The portion paid to gift recipients is recognized as cost of revenues.

Mobile marketing. We provide advertising and marketing solutions to customers for promotion of their brands and conduction of effective marketing activities through their mobile applications.

Display-based mobile marketing services

For display-based online advertising services such as banners- and location-based advertising on mobile applications, we have determined that our mobile marketing services represent one performance obligation. Accordingly, we recognize mobile marketing revenue ratably over the period that the advertising is provided relevant commencing on the date the relevent customer’s advertisement is displayed, or based on the number of times that the advertisement has been displayed for cost per thousand impressions advertising arrangements.

Performance-based mobile marketing services

We also enable advertising customers to place links, on our mobile platform on a pay-for-effectiveness basis, which is referred to as the cost for performance model. We charge fees to advertising customers based on the effectiveness of advertising links, which is measured by active clicks. We have determined that our mobile marketing services represent one performance obligation. Accordingly, we recognize mobile marketing revenue based on sales of effective clicks. We estimated the revenues based on our internal data, which is confirmed with respective customers periodically, or recognize the revenue based on a fixed unit price.

Our revenue transactions are based on standard business terms and conditions, which are recognized net of agency rebates, if applicable.

Mobile Games. We publish licensed mobile games developed by third-party game developers and our self-developed mobile games to game players through our mobile application.

Licensed mobile games services

We generate revenue from offering services of mobile games developed by third-party game developers. All of the licensed games can be accessed and played by game players directly through our mobile game platform. We primarily view the game developers to be our customers and considers our performance obligation under the agreements with the game developers to be the promotion of the game developers’ games. We generally collect payments from game players in connection with the sale of in-game currencies and remits certain agreed-upon percentages of the proceeds to the game developers. Purchases of in-game currencies are not refundable after they have been sold unless there are unused in-game currencies at the time a game is discontinued. Typically, a game will only be discontinued when the monthly revenue generated by a game becomes consistently insignificant. We do not currently expect to pay any material cash refunds to game players or game developers in connection with a discontinued game. The majority of the licensed mobile games revenue is derived from non-exclusive mobile games services further discussed below.

Non-exclusive licensed mobile games services

We enter into non-exclusive agreements with the game developers and offers our mobile game platform for the mobile games developed by the game developers. We have single performance obligation which includes offering their mobile game platform for the game developers. We have determined that we are not the principal in the transaction and accordingly, revenues derived from the sale of in-game currencies are recorded net of remittances to game developers and commission fees made to third-party application stores and other payment channels. Revenue is further recognized at the end of the estimated consumption date by individual game (i.e., the estimated date in-game currencies are consumed within the game), which is typically within a short period of time ranging from two to three days after the purchase of the in-game currencies.

73

Self-developed mobile games

In February 2015, we launched one self-developed game on its platform and started to generate revenues by in-game sales of virtual items. We have determined that we have a single performance obligation to the players who purchased the virtual items to gain an enhanced game-playing experience over the playing period of the paying players. Accordingly, we recognize revenues ratably over the estimated average period of player relationship starting from the point in time when the players purchase the virtual items and once all other revenue recognition criteria are met. We operated eight and four self-developed mobile games as of December 31, 2017 and 2018, respectively. The estimated periods of the player relationship ranged from 56 to 79 days as of December 31, 2017, and was 77 days as of December 31, 2018. We have determined that we are the principle in fulfilling all obligations related to the mobile game operations for self-developed games. Accordingly, we recognized revenues on a gross basis. Commission fees paid to third-party application stores and other payment channels are recorded as cost of revenues.

Other Services. Revenues from other services in the year ended December 31, 2018 mainly consisted of revenues generated from advertisement resulting from the broadcasting of one television program produced by us. During the year ended December 31, 2018, we entered into an agreement with a television station, under which we are responsible for the production of the television program content, which was completed by December 31, 2018. The television station was responsible for providing advertising and marketing solutions to customers in addition to broadcasting television program content. Revenue generated from the above is in the form of advertising fees, shared between the television station and us based on a pre-determined percentage stated in the agreement. We determined that our television content production service represented one performance obligation. The broadcasting of the content was completed in the year ended December 31, 2018 and the revenue was recognized ratably during the period when the content was broadcasted on the television station.

Consolidation of Affiliated Entities

PRC regulations currently limit direct foreign ownership of business entities providing value-added telecommunications services, advertising services and internet services in the PRC where certain licenses are required for the provision of such services. To comply with these PRC regulations, we conduct a substantial majority of our business through our VIEs and their subsidiaries.

Our wholly-owned PRC subsidiaries, or the WFOEs, hold the power to direct the activities of our VIEs and their subsidiaries that most significantly affect our economic performance and bears the economic risks and receives the economic benefits of our VIEs and their subsidiaries through a series of contractual agreements with VIEs and/or their nominee shareholders, including:

Based on the advice of Han Kun Law Offices, our PRC legal counsel, we believe the above contractual agreements are currently legally enforceable under PRC law and regulations.

More specifically, through these contractual agreements, we believe that the nominee shareholders of our VIEs do not have the direct or indirect ability to make decisions regarding the activities of our VIEs that could have a significant impact on the economic performance of our VIEs because all of the voting rights of our VIEs’ nominee shareholders have been contractually transferred to our VIEs. Therefore, we have effective control over our VIEs. In addition, we believe that our ability to exercise effective control, together with the exclusive cooperation agreements, as supplemented, exclusive call option agreement and equity interest pledge agreement, give us the rights to receive substantially all of the economic benefits from our VIEs. Hence, we believe that the nominee shareholders of our VIEs do not have the rights to receive the expected residual returns of our VIEs, as such rights have been transferred to our VIEs. We evaluated the rights we obtained through entering into these contractual agreements and concluded we have the power to direct the activities that most significantly affect our VIEs’ economic performance and also have the rights to receive the economic benefits of our VIEs that could be significant to our VIEs.

74

Accordingly, we are the primary beneficiary of our VIEs and have consolidated the financial results of our VIEs and their subsidiaries in our consolidated financial statements.

However, uncertainties in the PRC legal system could limit our ability to enforce these contractual arrangements and if the shareholders of our VIEs were to reduce their shareholdings in our company, their interests may diverge from our interests, which may increase the risk that they would act contrary to the contractual arrangements, such as causing our VIEs to not pay service fees under the contractual arrangements when required to do so. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Corporate Structure—We rely on contractual arrangements with our consolidated affiliated entities and their respective shareholders for our operations in China, which may not be as effective in providing operational control as direct ownership.”

Income Taxes

In preparing our consolidated financial statements, we must estimate our income taxes in each of the jurisdictions in which we operate. We estimate our actual tax exposure and assess temporary differences resulting from different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which we include in our consolidated balance sheet. We must then assess the likelihood that we will recover our deferred tax assets from future taxable income. If we believe that recovery is not likely, we must establish a valuation allowance. To the extent we establish a valuation allowance or increase this allowance, we must include an expense within the tax provision in our consolidated statement of operations. We adopted ASU No. 2015-17, Balance Sheet Classification of Deferred Taxes, or ASU 2015-17, in the first quarter of 2017 and classified all deferred taxes assets and liabilities as noncurrent as of December 31, 2017 and 2018. We did not retrospectively apply the changes to the prior years.

Management must exercise significant judgment to determine our provision for income taxes, our deferred tax assets and liabilities and any valuation allowance recorded against our net deferred tax assets. We base the valuation allowance on our estimates of taxable income in each jurisdiction in which we operate and the period over which our deferred tax assets will be recoverable. If actual results differ from these estimates or we adjust these estimates in future periods, we may need to establish an additional valuation allowance, which could materially impact our financial position and results of operations.

U.S. GAAP requires that an entity recognize the impact of an uncertain income tax position on the income tax return at the largest amount that is more likely than not to be sustained upon audit by the relevant tax authority. If we ultimately determine that payment of these liabilities will be unnecessary, we will reverse the liability and recognize a tax benefit during that period. Conversely, we record additional tax charges in a period in which we determine that a recorded tax liability is less than the expected ultimate assessment. We did not recognize any significant unrecognized tax benefits during the periods presented in this annual report.

Uncertainties exist with respect to the application of the New EIT Law to our operations, specifically with respect to our tax residency status. The New EIT Law specifies that legal entities organized outside of the PRC will be considered residents for PRC income tax purposes if their “de facto management bodies” are located within the PRC. The New EIT Law’s implementation rules define the term “de facto management bodies” as “establishments that carry out substantial and overall management and control over the manufacturing and business operations, personnel, accounting, properties, etc. of an enterprise.”

Because of the uncertainties resulted from limited PRC tax guidance on the issue, it is uncertain whether our legal entities organized outside of the PRC constitute residents under the New EIT Law. If one or more of our legal entities organized outside of the PRC were characterized as PRC tax residents, the impact would adversely affect our results of operations. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China.”

The Useful Lives of Property and Equipment and Intangible Assets

Property and equipment are stated at historical cost less accumulated depreciation. Depreciation is computed using the straight-line method over the estimated useful lives of the assets, generally from three to five years. Intangible assets acquired through business acquisitions are recognized as assets separate from goodwill if they satisfy either the “contractual-legal” or “separability” criterion. Judgment is required to determine the estimated useful lives of assets, especially for intangible assets arising from the acquisitions, including determining how long existing intangible assets can benefit us. Changes in these estimates and assumptions could materially impact our financial position and results of operations.

75

Impairment of Long-Lived Assets Other Than Goodwill

We review our long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may no longer be recoverable. When these events occur, we measure impairment by comparing the carrying value of the long-lived assets to the estimated undiscounted future cash flows expected to result from the use of the assets and their eventual disposition. If the sum of the expected undiscounted cash flow is less than the carrying amount of the assets, we would recognize an impairment loss based on the fair value of the assets.

We recorded impairment losses of RMB nil, RMB1.3 million and RMB nil for long-lived assets other than goodwill for the years ended December 31, 2016, 2017 and 2018, respectively.

Impairment of Goodwill

Goodwill represents the excess of the purchase price over the fair value of identifiable net assets acquired in business combinations. Goodwill is not amortized but is tested for impairment annually, or more frequently if events or changes in circumstances indicate that it might be impaired.

Goodwill is tested for impairment at the reporting unit level on an annual basis and between annual tests, if an event occurs or circumstances change that would more likely than not reduce the fair value of a reporting unit below its carrying value. These events or circumstances could include a significant change in the stock prices, business climate, legal factors, operating performance indicators, competition, or sale or disposition of a significant portion of a reporting unit.

Application of the goodwill impairment test requires judgment, including the identification of reporting units, assignment of assets and liabilities to reporting units, assignment of goodwill to reporting units, and determination of the fair value of each reporting unit. The estimation of fair value of each reporting unit using a discounted cash flow methodology also requires significant judgments, including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for our business, estimation of the useful life over which cash flows will occur, and determination of our weighted average cost of capital. The estimates used to calculate the fair value of a reporting unit change from year to year based on operating results and market conditions. Changes in these estimates and assumptions could materially affect the determination of fair value and goodwill impairment for the reporting unit.

In order to test goodwill for impairment, we first assess qualitative factors to determine whether it is “more likely than not” that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. If it is more likely than not that the fair value of a reporting unit is less than its carrying amount, goodwill is then tested following a two-step process. The first step compares the fair value of each reporting unit to its carrying amount, including goodwill. If the fair value of each reporting unit exceeds its carrying amount, goodwill is not considered to be impaired and the second step will not be required. If the carrying amount of a reporting unit exceeds its fair value, the second step compares the implied fair value of goodwill to the carrying value of a reporting unit’s goodwill.

The implied fair value of goodwill is determined in a manner similar to accounting for a business combination with the allocation of the assessed fair value determined in the first step to the assets and liabilities of the reporting unit. The excess of the fair value of the reporting unit over the amounts assigned to the assets and liabilities is the implied fair value of goodwill. An impairment loss is recognized for any excess in the carrying value of goodwill over the implied fair value of goodwill.

We recorded RMB nil, RMB nil and RMB nil impairment losses during the years ended December 31, 2016, 2017 and 2018, respectively. We did not have goodwill at any of our reporting units that are at risk of impairment at December 31, 2017 and 2018.

Business combinations

Business combinations are recorded using the acquisition method of accounting in accordance with Accounting Standards Codification, or the ASC, 805 “Business Combinations”. The cost of an acquisition is measured as the aggregate of the acquisition date fair value of the assets transferred to the sellers and liabilities incurred by us and equity instruments issued. Identifiable assets and liabilities acquired or assumed are measured separately at their fair values as of the acquisition date, irrespective of the extent of any noncontrolling interests. The purchase price of business acquisition is allocated to the tangible assets, liabilities, identifiable intangible assets acquired and non-controlling interest, if any, based on their estimated fair values as of the acquisition date. The excess of the purchase price over those fair values is recorded as goodwill. Acquisition-related expenses and restructuring costs are expensed as incurred.

We adopted Accounting Standard Update, or ASU, 2017-01 “Business Combination (Topic 805): Clarifying the Definition of a Business” on January 1, 2018 and applied the new definition of a business prospectively for acquisitions made subsequent to December 31, 2017. Upon the adoption of ASU 2017-01, a new screen test is introduced to evaluate whether a transaction should be accounted for as an acquisition and/or disposal of a business versus assets. In order for a purchase to be considered an acquisition of a business, and receive business combination accounting treatment, the set of transferred assets and activities must include, at a minimum, an input and a substantive process that together significantly contribute to the ability to create outputs. If substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or a group of similar identifiable assets, then the set of transferred assets and activities is not a business. The adoption of this standard requires future purchases to be evaluated under the new framework.

Long-term investments

Our long-term investments primarily consist of equity securities without readily determinable fair values and equity method investments.

76

Equity securities without readily determinable fair value

We adopted ASC Topic 321, Investments—Equity Securities, or ASC 321, on January 1, 2018. Prior to 2018, we carried at cost our investments in investees that do not have readily determinable fair value and over which we do not have significant influence, in accordance with ASC Subtopic 325-20, Investments-Other: Cost Method Investments. We regularly evaluate the impairment of the cost method investments based on the performance and financial position of the investee as well as other evidence of market value. Such evaluation includes, but is not limited to, reviewing the investee’s cash position, recent financing, projected and historical financial performance. An impairment loss is recognized in earnings equal to the excess of the investment’s cost over its fair value at the balance sheet date of the reporting period for which the assessment is made. The fair value would then become the new cost basis of the investment.

Subsequent to our adoption of ASC 321, for equity securities without readily determinable fair value and that do not qualify for the existing practical expedient used in ASC Topic 820, Fair Value Measurements and Disclosures, or ASC 820, we elected to use the measurement alternative to measure those investments. Under that method, we measure that investment at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any.

Pursuant to ASC 321, for those equity securities that we elect to use the measurement alternative, we make a qualitative assessment of whether the investment is impaired at each reporting date. If a qualitative assessment indicates that the investment is impaired, we have to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, we recognize an impairment loss in net income equal to the difference between the carrying value and fair value.

Equity method investments

The investee companies over which we have the ability to exercise significant influence, but do not have a controlling interest are accounted for using the equity method. Significant influence is generally considered to exist when we have an ownership interest in the voting stock of the investee between 20% and 50%. Other factors, such as representation in the investee’s board of directors, voting rights and the impact of commercial arrangements, are also considered in determining whether the equity method of accounting is appropriate. For the investment in limited partnerships, where we hold less than a 20% equity or voting interest, our influence over the partnership operating and financial policies is determined to be more than minor. Accordingly, we account for these investments as equity method investments.

Under the equity method of accounting, the affiliated company’s accounts are not reflected within our consolidated balance sheets and statements of operations; however, our share of the earnings or losses of the affiliated company is reflected in the caption “share of income on equity method investments” in the consolidated statements of operations.

An impairment change is recorded if the carrying amount of the investment exceeds its fair value and this condition is determined to be other-than-temporary.

We estimate the fair value of the investee company based on comparable quoted price for similar investment in active market, if applicable, or discounted cash flow approach which requires significant judgments, including the estimation of future cash flows, which is dependent on internal forecasts, the estimation of long term growth rate of a company’s business, the estimation of the useful life over which cash flows will occur, and the determination of the weighted average cost of capital.

We recorded impairment losses of RMB39.3 million, RMB30.1 million and RMB43.2 million (US$6.3 million) for long-term investments during the years ended December 31, 2016, 2017 and 2018, respectively.

77

Share-based Compensation

Share-based payment transactions with employees and executives are measured based on the grant date fair value of the equity instrument issued and recognized as compensation expense net of a forfeiture rate on a straight-line basis, over the requisite service period, with a corresponding impact reflected in additional paid-in capital.

We classify share-based compensation with cash settlement features as liabilities. The percentage of the fair value that is accrued as compensation cost at the end of each period equal the percentage of the requisite service that has been rendered at that date. We recognize the changes in fair value of the liability classified award that occur during the requisite service period as compensation cost over that period. These awards typically vest over a period of four years, but may fully vest due to the achievement of certain performance conditions. We recognize the share-based compensation expense on an accelerated basis if it is probable that the performance condition will be achieved.

We measure share awards issued to consultants at fair value at the earlier of the commitment date or the date the services are completed and recognized over the period the services are provided.

The estimate of forfeiture rate is adjusted over the requisite service period to the extent that actual forfeiture rate differs, or is expected to differ, from such estimates. We recognize changes in estimated forfeiture rate through a cumulative catch-up adjustment in the period of change.

Changes in the terms or conditions of share options are accounted as a modification. We calculate the excess of the fair value of the modified option over the fair value of the original option immediately before the modification, measured based on the share price and other pertinent factors at the modification date. For vested options, we recognize incremental compensation cost in the period that the modification occurred. For unvested options, we recognize, over the remaining requisite service period, the sum of the incremental compensation cost and the remaining unrecognized compensation cost for the original award on the modification date.

Determining the fair value of share-based awards requires significant judgment. We estimate the fair value of share options using the Black-Scholes valuation model or binomial tree pricing model, which requires inputs such as the fair value of our ordinary shares, risk-free interest rate, expected dividend yield, expected life and expected volatility.

Recent Accounting Pronouncements

A list of recent accounting pronouncements that are relevant to us is included in note 2 to our consolidated financial statements, which are included in this annual report.

As of December 31, 2018, we have financed our operations primarily through net cash provided by operating activities, as well as the issuance of equity and convertible note securities. As of December 31, 2016, 2017 and 2018, we had RMB1,788.3 million, RMB4,462.2 million and RMB2,468.0 million (US$359.0 million), respectively, in cash and cash equivalents. Our cash and cash equivalents primarily consist of cash on hand and highly liquid investments, which are unrestricted from withdrawal or use, or which have original maturities of three months or less when purchased. We believe that our current cash and cash equivalents and our anticipated cash flows from operations will be sufficient to meet our anticipated working capital requirements and capital expenditures for the next 12 months. We may, however, need additional capital in the future to fund our continued operations.

In the future, we may rely significantly on dividends and other distributions paid by our PRC subsidiary for our cash and financing requirements. There may be restrictions on the dividends and other distributions by our PRC subsidiary. The PRC tax authorities may require us to adjust our taxable income under the contractual arrangements that our PRC subsidiary currently has in place with our consolidated affiliated entity in a way that could materially and adversely affect the ability of our PRC subsidiary to pay dividends and make other distributions to us. In addition, under PRC laws and regulations, our PRC subsidiary may pay dividends only out of its accumulated profits as determined in accordance with PRC accounting standards and regulations. Our PRC subsidiary is required to set aside at least 10% of its accumulated after-tax profits each year, if any, to fund a statutory reserve fund, until the aggregate amount of such fund reaches 50% of its respective registered capital. At its discretion, our PRC subsidiary may allocate a portion of its after-tax profits based on PRC accounting standards to staff welfare and bonus funds. The reserve fund and the staff welfare and bonus funds cannot be distributed as cash dividends. See “Item 3. Key Information—D. Risk Factors—Risks Related to Our Corporate Structure—We may rely on dividends paid by our PRC subsidiaries to fund cash and financing requirements. Any limitation on the ability of our PRC subsidiaries to pay dividends to us could have a material adverse effect on our ability to conduct our business and to pay dividends to holders of the ADSs and our ordinary shares.” Furthermore, our investments made as registered capital and additional paid-in capital of our PRC subsidiary, consolidated affiliated entity and its subsidiaries are also subject to restrictions on their distribution and transfer according to PRC laws and regulations.

As a result, our PRC subsidiaries, consolidated affiliated entities and their subsidiaries in China are restricted in their ability to transfer their net assets to us in the form of cash dividends, loans or advances. As of December 31, 2018, the amount of the restricted net assets, which represents registered capital and additional paid-in capital cumulative appropriations made to statutory reserves, was RMB1,477.3 million (US$214.9 million). As of December 31, 2018, we held cash and cash equivalents of RMB460.0 million (US$66.9 million) in aggregate outside of the PRC and RMB2,008.0 million (US$292.0 million) in aggregate in the PRC, of which RMB2,007.8 million (US$292.0 million) was denominated in RMB and RMB132,050 (US$19,206) was denominated in U.S. dollars. Of such cash and cash equivalents held in the PRC, our PRC subsidiary held cash and cash equivalents in the amount of RMB131,983 (US$19,196) and RMB505.4 million (US$73.5 million), and our consolidated affiliated entity and its subsidiaries held cash and cash equivalents in the amount of RMB66 (US$10) and RMB1,502.4 million (US$218.5 million).

78

As an offshore holding company, we are permitted under PRC laws and regulations to provide funding from the proceeds of our offshore fund raising activities to our PRC subsidiary only through loans or capital contributions, and to our consolidated affiliated entity and its subsidiaries only through loans, in each case subject to the satisfaction of the applicable government registration and approval requirements. See “Item 3. Key Information—D. Risk Factors—Risks Related to Doing Business in China—PRC regulation of loans to, and direct investment in, PRC entities by offshore holding companies and governmental control of currency conversion may restrict or prevent us from using offshore funds to make loans to our PRC subsidiaries and consolidated affiliated entities and their subsidiaries, or to make additional capital contributions to our PRC subsidiaries.” As a result, there is uncertainty with respect to our ability to provide prompt financial support to our PRC subsidiaries and consolidated affiliated entities when needed. Notwithstanding the foregoing, our PRC subsidiaries may use their own retained earnings (rather than RMB converted from foreign currency denominated capital) to provide financial support to our consolidated affiliated entities either through entrustment loans from our PRC subsidiaries to our consolidated affiliated entities or direct loans to such consolidated affiliated entities’ nominee shareholders, which would be contributed to the consolidated variable entities as capital injections. Such direct loans to the nominee shareholders would be eliminated in our consolidated financial statements against the consolidated affiliated entities’ share capital.

Our full-time employees in the PRC participate in a government-mandated contribution plan pursuant to which certain pension benefits, medical care, unemployment insurance, employee housing fund and other welfare benefits are provided to such employees. We accrue for these benefits based on certain percentages of the employees’ salaries. The total provisions for such employee benefits were RMB60.4 million, RMB95.2 million and RMB167.0 million (US$24.3 million) in 2016, 2017 and 2018, respectively. We expect our contribution towards such employee benefits to increase in the future as we continue to expand our workforce and as salary levels of our employees continue to increase.

The following table sets forth a summary of our cash flows for the periods indicated:

Anticipated Use of Cash                

We intend to continue to invest in our research and development capabilities to grow our user base and enhance user experience.

On March 12, 2019, we declared a special cash dividend in the amount of US$0.62 per ADS, or US$0.31 per ordinary share.

Operating Activities

Net cash provided by operating activities amounted to RMB3,327.7 million (US$484.0 million) in 2018, which was primarily attributable to a net income of RMB2,788.5 million (US$405.6 million), adjusted for non-cash items of RMB814.8 million (US$118.5 million) and a decrease of RMB275.6 million (US$40.1 million) in working capital.

The increase in accounts payable was mainly attributable to (i) an increase in revenue-sharing payable to live broadcasters, and (ii) an increase in bandwidth cost payable to IT service suppliers. The increase in income tax payable was mainly because we generated higher profit in 2017 and the tax holiday of one of our major profit generating entities changed from 100% exemption to 50% exemption of income tax in 2017. The increase in deferred revenue was mainly attributable to the increase in live video service revenues paid in advance. The increase in prepaid expenses and other current assets was mainly attributable to (i) an increase in customer payment to our account through third-party channels and cash deposited at the third-party payment channels by us for the broadcasters to withdraw their revenue sharing, (ii) an increase in advance payment made to suppliers for advertising fees and live video broadcasting service fees and (iii) an increase in rental fees we prepaid for our expanding office space.

Holding Company Structure

Our company is a holding company with no material operations of its own. We conduct our operations primarily through our subsidiaries and our consolidated affiliated entities and their subsidiaries in China. As a result, our ability to pay dividends depends upon dividends paid by our subsidiaries. If our subsidiaries or any newly formed subsidiaries incur debt on their own behalf in the future, the instruments governing their debt may restrict their ability to pay dividends to us. In addition, our subsidiaries are permitted to pay dividends to us only out of their retained earnings, if any, as determined in accordance with PRC accounting standards and regulations. Under PRC law, each of our PRC subsidiaries and our consolidated affiliated entities is required to set aside at least 10% of their after-tax profits each year, if any, to fund a statutory reserve until such reserve reaches 50% of their registered capital. Although the statutory reserves can be used, among other ways, to increase the registered capital and eliminate future losses in excess of retained earnings of the respective companies, the reserve funds are not distributable as cash dividends except in the event of liquidation. As a result of these PRC laws and regulations, the capital and statutory reserves restricted which represented the amount of net assets of our relevant subsidiaries in PRC not available for distribution were RMB1,477.3 million (US$214.9 million) as of December 31, 2018.

Capital Expenditures

Our capital expenditures amounted to RMB46.8 million, RMB218.6 million and RMB242.8 million (US$35.3 million) in 2016, 2017 and 2018, respectively. In the past, our capital expenditures were principally incurred to purchase servers, computers and other office equipment, and to pay for leasehold improvements for our offices. As our business expands, we may purchase new servers, computers and other equipment in the future, as well as make leasehold improvements.

We focus our research and development efforts on the continual improvement and enhancement of our platform’s features and services, as well as the design and development of games that are suitable for publishing on our own platform. We have a large team of engineers and developers, which accounted for approximately 55% of our employees as of December 31, 2018. Most of our engineers and developers are based in our headquarters in Beijing.

For the three years ended December 31, 2016, 2017 and 2018, our research and development expenditures, including share-based compensation expenses for research and development personnel, were RMB208.6 million, RMB346.1 million and RMB760.6 million (US$110.6 million), respectively. For the year ended December 31, 2018, our research and development expenditures represented 5.7% of our total revenues. Our research and development expenses primarily consist of salaries and benefits, including share-based compensation expenses, for research and development personnel and technical service fees. Expenditures incurred during the research phase are expensed as incurred. We expect our research and development expenses to increase as we expand our research and development team to develop new features and services for our platform and further enhance our big data analytical capabilities.

Other than as disclosed elsewhere in this annual report, we are not aware of any trends, uncertainties, demands, commitments or events for the year ended December 31, 2018 that are reasonably likely to have a material and adverse effect on our net revenues, income, profitability, liquidity or capital resources, or that would cause the disclosed financial information to be not necessarily indicative of future results of operations or financial conditions.

We have not entered into any financial guarantees or other commitments to guarantee the payment obligations of any third parties. We have not entered into any derivative contracts that are indexed to our shares and classified as shareholder’s equity or that are not reflected in our consolidated financial statements. Furthermore, we do not have any retained or contingent interest in assets transferred to an unconsolidated entity that serves as credit, liquidity or market risk support to such entity for such assets. We do not have any obligation, including a contingent obligation, arising out of a variable interest in any unconsolidated entity that we hold and material to us, where such entity provides financing, liquidity, market risk or credit risk support to us or engages in leasing, hedging or research and development services with us.
