Control and operational issues pertaining to business activities that we conduct pursuant to joint ventures with other parties;



•

Difficulties we may incur in implementing our acquisition strategy;

Unexpected adjustments and cancellations related to our backlog.

        Other factors that may affect our businesses, financial position or results of operations include:

•

Special risks of our ability to obtain debt financing or otherwise raise capital to meet required working capital needs and to support potential future acquisition activities;



•

Special risks of international operations, including uncertain political and economic environments, acts of terrorism or war, potential incompatibilities with foreign joint venture partners, foreign currency fluctuations, civil disturbances and labor issues; and

they identify certain important factors that could cause actual results to differ materially from those in the forward-looking statements and from historical trends. Those cautionary statements are not exclusive and are in addition to other factors discussed elsewhere in this Form 10-K, in our other filings with the Securities and Exchange Commission or in materials incorporated therein by reference.

Item 1.    Business.

General

        Hill International, Inc., with 4,100 professionals in 100 offices worldwide, provides program management, project management, construction management, construction claims and other consulting services primarily to the buildings, transportation, environmental, energy and industrial markets. Engineering News-Record magazine recently ranked Hill as the ninth largest construction management firm and tenth largest program management firm in the United States. The terms "Hill", the "Company", "we", "us" and "our" refer to Hill International, Inc.

        We compete for business based on a variety of factors such as technical capability, global resources, price, reputation and past experience, including client requirements for substantial experience in similar projects and claims work. We have developed significant long-standing relationships, which bring us repeat business and would be very difficult to replicate. We have an excellent reputation for developing and rewarding employees which allows us to attract and retain superior professionals. In addition, we believe there are high barriers to entry for new competitors especially in the project management market.

Our Growth Strategy

        Our growth strategy is to increase our revenue through organic growth and expand our geographic reach and service offerings through strategic acquisitions. We seek to achieve these objectives through the following strategies:

•

Continue to Take Advantage of Organic Growth Opportunities.  We have long-standing relationships with a number of public and private sector entities. Meeting our clients' diverse needs in managing construction risk and generating repeat business from our clients to expand our project base is one of our key growth strategies. We accomplish this objective by providing a broad range of project management and construction claims consulting services in a wide range of geographic areas that support our clients during every phase of a project, from concept through completion. We believe that nurturing our existing client relationships expands our project base through repeat business. In addition, we strategically open new offices to expand into new geographic areas and we aggressively hire individuals with significant contacts to accelerate the growth of these new offices and to strengthen our presence in existing markets.



•

Continue to Pursue Acquisitions.  We operate in a highly fragmented industry with many smaller, regional competitors. Our acquisition strategy allows us to manage risk by diversifying our services, which enables us to compete better by integrating capabilities and obtaining new relationships. We pursue acquisitions primarily for three reasons: to expand into new geographic markets; add to professional resources and gain critical mass in existing markets to compete more effectively; and to enhance our specialization and capability in certain strategic areas. We intend to continue to pursue both U.S. acquisitions to round out our domestic presence and enhance capabilities in specific areas and foreign acquisitions that bring new relationships as well as widen our geographic base to offer our global capabilities.



•

Strengthen Professional Resources.  Our biggest asset is the people that work for Hill. We intend to continue spending significant time recruiting and retaining the best and the brightest to improve our competitive position. Our independent status has attracted top project management

talent with varied industry experience. Additionally, our construction claims business provides us with a strong base of expertise that allows knowledge transfer across our businesses. We believe maintaining and bolstering our team will enable us to continue to grow our business.

Reporting Segments

        We primarily operate through two reporting segments: the Project Management Group and the Construction Claims Group. Our total revenue consists of two components: consulting fee revenue ("CFR") and reimbursable expenses. Reimbursable expenses are reflected in equal amounts in both total revenue and total direct expenses. Because these revenue/costs are subject to significant fluctuation from year to year, we measure the performance of many of our key operating metrics as a percentage of CFR, as we believe that this is a better and more consistent measure of operating performance than total revenue. Throughout this report we have used CFR as the denominator in many of our ratios. The following table sets forth the amount and percentage of CFR from our operations in each reporting segment for each of the past three fiscal years (dollars in thousands):

Consulting Fee Revenue ("CFR")

Project Management

        Our Project Management Group provides fee-based or "agency" construction management services to our clients, leveraging our construction expertise to identify potential trouble, difficulties and sources of delay on a construction project before they develop into costly problems. Our services include program management, project management, construction management, project management oversight, troubled project turnaround, staff augmentation, estimating and cost management, project labor agreement consulting, commissioning, labor compliance and other services.

        Our clients are typically billed a negotiated multiple of the actual direct cost of each consultant assigned to a project and we are reimbursed for our out-of-pocket expenses. We believe our fee-based consulting has significant advantages over traditional general contractors. Specifically, because we do not assume project completion risk, our fee-based model eliminates many of the risks typically associated with providing "at risk" construction services.

        We have managed all phases of the construction process on behalf of project owners and developers, from concept through completion. Specific activities that we undertake as part of these services include: planning, scheduling, estimating, budgeting, design review, constructability analyses, value engineering, regulatory compliance, development of project procedures, procurement, project reporting, expediting, inspection, quality assurance/quality control, safety oversight, contract administration, change order processing, claims management, and on-site management of contractors, subcontractors and suppliers.

Construction Claims

        Our Construction Claims Group advises clients in order to assist them in preventing or resolving claims and disputes based upon schedule delays, cost overruns and other problems on major construction projects worldwide.

Table of Contents

        We may be retained as a claims consultant at the onset of a project, during the course of a project or upon the completion of a project. We assist owners or contractors in adversarial situations as well as in situations where an amicable resolution is sought. Specific activities that we undertake as part of these services include claims preparation, analysis and review, litigation support, cost/damages assessment, delay/disruption analysis, adjudication, risk assessment, lender advisory, expert witness testimony and other services.

        Clients are typically billed based on an hourly rate for each consultant assigned to the project, and we are reimbursed for our out-of-pocket expenses. Our claims consulting clients include participants on all sides of a construction project, including owners, contractors, subcontractors, architects, engineers, attorneys, lenders and insurance companies.

Global Business

        We operate worldwide and currently have approximately 100 offices in nearly 40 countries. The following table sets forth the amount and percentage of our CFR by geographic region for each of the past three fiscal years (dollars in thousands):

Consulting Fee Revenue by Geographic Region:

Growth Organically and Through Acquisitions

        Over the years, our business has expanded through organic growth and the acquisition of a number of project management and claims consulting businesses. Over the past 16 years, we have completed 22 acquisitions of project management and claims consulting businesses.

        We believe that our industry includes a number of small regional companies in a highly fragmented market. We believe that we have significant experience and expertise in identifying, negotiating, completing and integrating acquisitions and view the acquisition of these smaller competitors as a key part of our growth strategy. Through our acquisitions, we gained entry into the United Kingdom, Spain, Mexico, Poland, Australia, Brazil and South Africa and expanded our presence in the United States. These transactions have enabled us to accelerate our growth, strengthen our geographic diversity and compete more effectively.

Clients

        Our clients consist primarily of the United States and other national governments, state and local governments, and the private sector. The following table sets forth our breakdown of CFR attributable to these categories of clients for each of the past three fiscal years (dollars in thousands):

Consulting Fee Revenue By Client Type:

        The following table sets forth the percentage of our consulting fee revenue contributed by each of our five largest clients for the years ended December 31, 2013, 2012 and 2011:

Business Development

        The process for acquiring business from each of our categories of clients is principally the same, by participating in a competitive request-for-proposal ("RFP") process, with the primary difference among clients being that the process for public sector clients is significantly more formal and complex than for private sector clients as a result of government procurement rules and regulations that govern the public-sector process.

        Although a significant factor in our business development consists of our standing in our industry, including existing relationships and reputation based on performance on completed projects, our marketing department undertakes a variety of activities in order to expand our exposure to potential new clients. These activities include media relations, advertising, promotions, market sector initiatives and maintaining our website and related web marketing. Media relations include placing articles that feature us and our personnel in trade publications and other media outlets. Our promotions include arranging speaking engagements for our personnel, participation in trade shows and other promotional activities. Market sector initiatives are designed to broaden our exposure to specific sectors of the construction industry, such as, for example, participating in or organizing industry seminars.

        For the year ended December 31, 2013, CFR from U.S. and foreign government contracts represented approximately 51.8% of our total CFR. Doing business with governments is complex and requires the ability to comply with intricate regulations and satisfy periodic audits. We believe that the ability to understand these requirements and to successfully conduct business with government agencies is a barrier to entry for smaller, less experienced competitors. Most government contracts, including

7

Table of Contents

those with foreign governments, are subject to termination by the government, to government audits and to continued appropriations.

        We are required from time to time to obtain various permits, licenses and approvals in order to conduct our business in many of the jurisdictions where we operate. Our businesses of providing project management and construction claims services are not subject to significant regulation by state, federal or foreign governments.

Contracts

        The price provisions of our contracts can be grouped into three broad categories: cost-plus, time and materials, and fixed-price. Cost-plus contracts provide for reimbursement of our costs and overhead plus a predetermined fee. Under some cost-plus contracts, our fee may be based partially on quality, schedule and other performance factors. We also enter into contracts whereby we bill our clients monthly at hourly billing rates. The hourly billing rates are determined by contract terms. For governmental clients, the hourly rates are generally calculated as salary costs plus overhead costs plus a negotiated profit percentage. For commercial clients, the hourly rate can be taken from a standard fee schedule by staff classification or it can be at a discount from this schedule. In some cases, primarily for foreign work, a monthly rate is negotiated rather than an hourly rate. This monthly rate is a build-up of staffing costs plus overhead and profit. We account for these contracts on a time-and-materials method, recognizing revenue as costs are incurred. Fixed-price contracts are accounted for using the "percentage-of-completion" method, wherein revenue is recognized as costs are incurred.

Backlog

        We believe a strong indicator of our future performance is our backlog of uncompleted projects under contract or awarded. Our backlog represents management's estimate of the amount of contracts and awards in hand that we expect to result in future consulting fee revenue. Project Management backlog is evaluated by management, on a project-by-project basis, and is reported for each period shown based upon the binding nature of the underlying contract, commitment or letter of intent, and other factors, including the economic, financial and regulatory viability of the project and the likelihood of the contract being extended, renewed or cancelled. Construction Claims backlog is based largely on management's estimates of future revenue based on known construction claims assignments. Because a significant number of construction claims may be awarded and completed within the same period, our actual construction claims revenue has historically exceeded backlog by a significant amount.

        Our backlog is important to us in anticipating and planning for our operational needs. Backlog is not a measure defined in U.S. generally accepted accounting principles, and our methodology for determining backlog may not be comparable to the methodology used by other companies in determining their backlog.

        At December 31, 2013, our backlog was a record $1,027,000,000, surpassing $1,000,000,000 for the first time in the Company's history, compared to approximately $923,000,000 at December 31, 2012. At December 31, 2013, backlog attributable to future work in Libya amounted to approximately $44,000,000. We estimate that approximately $394,000,000, or 38.4% of the backlog at December 31, 2013, will be recognized during our 2014 fiscal year.

        Although backlog reflects business that we consider to be firm, cancellations or scope adjustments may occur. Further, substantially all of our contracts with our clients may be terminated at will, in which case the client would only be obligated to us for services provided through the termination date. Historically, the impact of terminations and modifications on our realization of revenue from our backlog has not been significant, however, there can be no assurance that such changes will not be significant in the future. Furthermore, reductions of our backlog as a result of contract terminations and modifications may be offset by additions to the backlog.

8

Table of Contents

        We adjust backlog to reflect project cancellations, deferrals and revisions in scope and cost (both upward and downward) known at the reporting date. Future contract modifications or cancellations, however, may increase or reduce backlog and future revenue.

Competition

        The project management and claims consulting industries are highly competitive. We compete for contracts, primarily on the basis of technical capability, with numerous entities, including design or engineering firms, general contractors, other "pure" construction management companies, other claims consulting firms, the "Big Four" and other accounting firms, management consulting firms and other entities. Compared to us, many of these competitors are larger, well-established companies that have broader geographic scope and greater financial and other resources. During 2013, some of our largest project management competitors included: AECOM Technology Corp.; ARCADIS N.V.; Jacobs Engineering Group, Inc.; Parsons Brinckerhoff, Inc.; Parsons Corp.; Turner Construction Co.; and URS Corp. Some of our largest claims consulting competitors last year included: Exponent, Inc.; Navigant Consulting, Inc. and Systech Group, Ltd.

Insurance

        We maintain insurance covering professional liability, as well as for claims involving bodily injury and property damage. We have historically enjoyed a favorable loss ratio in all lines of insurance and our management considers our present limits of liability, deductibles and reserves to be adequate. We endeavor to reduce or eliminate risk through the use of quality assurance/control, risk management, workplace safety and similar methods to eliminate or reduce the risk of losses on a project. Although our actual rates have decreased, we have experienced and expect to continue to experience increases in the dollar amount of our insurance premiums because of the increase in our revenue.

Management

        We are led by an experienced management team with significant experience in the construction industry. Additional information about our executive officers follows.

Item 1A.    Risk Factors.

        Our business involves a number of risks, some of which are beyond our control. The risks and uncertainties described below could individually or collectively have a material adverse effect on our business, assets, profitability or prospects. While these are not the only risks and uncertainties we face, we believe that the more significant risks and uncertainties are as follows:

Risks Affecting the Business

Acts of terrorism, political, governmental and social upheaval and threats of armed conflicts in or around various areas in which we operate could limit or disrupt markets and our operations, including disruptions resulting from the evacuation of personnel, cancellation of contracts or the loss of personnel.

        Acts of terrorism, political, governmental and social upheaval and threats of armed conflicts in or around various areas in which we operate could limit or disrupt markets and our operations, including disruptions resulting from the evacuation of personnel, cancellation of contracts or the loss of personnel, and may affect timing and collectibility of our accounts receivable. Such events may cause

12

Table of Contents

further disruption to financial and commercial markets and may generate greater political and economic instability in some of the geographic areas in which we operate. In addition, any possible reprisals as a consequence of the wars and ongoing military action in the Middle East and Africa, such as acts of terrorism in the United States or elsewhere, could have a material adverse effect on our business, results of operations and financial position.

If our clients delay in paying or fail to pay amounts owed to us, it could have a material adverse effect on our liquidity, results of operations and financial condition.

        Accounts receivable represent the largest asset on our balance sheet. While we take steps to evaluate and manage the credit risks relating to our clients, economic downturns or other events can adversely affect the markets we serve and our clients ability to pay, which could reduce our ability to collect all amounts due from clients. In addition, the political unrest in countries in which we operate has impacted and may in the future impact our collections on accounts receivable. If our clients delay in paying or fail to pay us a significant amount of our outstanding receivables, it could have a material adverse effect on our liquidity, results of operations, and financial condition.

        For example, due to the political unrest in Libya in February 2011, we suspended our operations in and demobilized substantially all of our personnel from Libya. We have open but inactive contracts in Libya. During 2013 and early 2014, we received payments of approximately $9,200,000 from our client, the Libyan Organization for the Development of Administrative Centres ("ODAC"), for work performed prior to March 2011. The remaining accounts receivable balance with ODAC is now $50,800,000. Since the end of the Libyan civil unrest in October 2011, the Company has sought to recover its receivable from ODAC through ongoing negotiations rather than pursue its legal rights for payment under the contracts. The Company believes that this course of action provides the best likelihood for recovery as it could result in completion of and payment on the existing contracts as well as the potential for the award of new contracts. There is at present no agreement, understanding or timetable for further payments of Hill's accounts receivable from ODAC or a return to work on Hill's existing contracts. However, management believes that these payments, along with letters of credit of approximately $14,000,000 posted in our favor by ODAC, were made in good faith and are a positive indication that ODAC intends to satisfy its obligations to Hill. However, the Company cannot predict with certainty when, or if, the remaining accounts receivable will be paid by the Libyan authorities or when work will resume there. In the event that we do not realize any further payments, there could be a significant adverse impact on our results of operations and financial position.

Unfavorable global economic conditions could adversely affect our business, liquidity and financial results.

        The markets that we serve are cyclical and subject to fluctuation based on general global economic conditions and other factors. Unfavorable global economic conditions, including disruption of financial markets in the United States, Europe and elsewhere, could adversely affect our business and results of operations, primarily by limiting our access to credit and disrupting our clients' businesses. The reduction in financial institutions' willingness or ability to lend has increased the cost of capital and reduced the availability of credit. Although we currently believe that the financial institutions with which we do business will be able to fulfill their commitments to us, there is no assurance that those institutions will be able or willing to continue to do so, which could have a material adverse impact on our business. The current European debt crisis and related European restructuring efforts may cause the value of European currencies, including the Euro and British pound sterling, to deteriorate, thus reducing the purchasing power of European clients and reducing the translated amounts of U.S. dollar revenues. For the year ended December 31, 2013, 14.7% of our consulting fee revenue was attributable to European clients. In addition, continuation or worsening of general market conditions in the United States, Europe or other national economies important to our businesses may adversely affect our clients' level of spending, ability to obtain financing, and ability to make timely payments to us for our

services, which could require us to increase our allowance for doubtful accounts, negatively impact our days sales outstanding and adversely affect our results of operations.

We cannot be certain that we will be able to raise capital or obtain debt financing to meet required capital needs.

        We are currently party to a revolving credit agreement to assist in funding working capital needs. This agreement provides for a maximum total outstanding debt (that is, borrowings plus letters of credit) amounting to $65,000,000. The Company is required to comply with certain financial covenants with respect to leverage ratios and a fixed charge ratio as well as other covenants. If our operating results and financial liquidity are not as positive as we expect, that could cause us to be in violation of these covenants.

        In addition, our current revolving credit agreement may not provide us with sufficient credit to meet all of the future financial needs of our business. We may be unable to increase availability under our current revolving credit agreement or obtain alternative debt or equity financing on terms that would be acceptable to us, or at all.

We may be unable to win new contract awards if we cannot provide clients with letters of credit, bonds or other forms of guarantees.

        In certain international regions, primarily the Middle East, it is industry practice for clients to require letters of credit, bonds, bank guarantees or other forms of guarantees. These letters of credit, bonds or guarantees indemnify our clients if we fail to perform our obligations under our contracts. We currently have relationships with various domestic and international banking institutions to assist us in providing clients with letters of credit or guarantees. Because of current overall limitations in worldwide banking capacity, we may find it difficult to find sufficient bonding capacity to meet our future bonding needs. Failure to provide credit enhancements on terms required by a client may result in our inability to compete or win a project.

International operations and doing business with foreign governments expose us to legal, political, operational and economic risks in different countries and currency exchange rate fluctuations could adversely affect our financial results.

        Our international operations contributed 77.0%, 72.6% and 71.9% of our consulting fee revenue for the years ended December 31, 2013, 2012 and 2011, respectively. There are risks inherent in doing business internationally, including:

•

Lack of developed legal systems to enforce contractual rights;



•

Foreign governments may assert sovereign or other immunity if we seek to assert our contractual rights thus depriving us of any ability to seek redress against them;



•

Greater difficulties in managing and staffing foreign operations;



•

Differences in employment laws and practices which could expose us to liabilities for payroll taxes, pensions and other expenses;



•

Inadequate or failed internal controls, processes, people, and systems associated with foreign operations;



•

Increased logistical complexity;



•

Increased selling, general and administrative expenses associated with managing a larger and more global business;



•

Greater risk of uncollectible accounts and longer collection cycles;

Imposition of governmental controls;



•

Political and economic instability;

Changes in U.S. and other national government policies affecting the markets for our services and our ability to do business with certain foreign governments or their political leaders;



•

Conflict between U.S. and non-U.S. law;

Changes in regulatory practices, tariffs and taxes;



•

Less well established bankruptcy and insolvency procedures;



•

Potential non-compliance with a wide variety of non-U.S. laws and regulations; and



•

General economic, political and civil conditions in these foreign markets.

        Any of these factors could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We operate in many different jurisdictions and we could be adversely affected by any violations of the U.S. Foreign Corrupt Practices Act or similar worldwide and local anti-corruption laws.

        The U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act of 2010 and similar worldwide and local anti-corruption laws in other jurisdictions, generally prohibit companies and their intermediaries from making improper payments to officials for the purpose of obtaining or retaining business. Our internal policies mandate compliance with these anti-corruption laws. The policies also are applicable to agents through which we do business in certain non-U.S. jurisdictions. We operate in many parts of the world that have experienced governmental corruption to some degree, and in certain circumstances, strict compliance with anti-corruption laws may conflict with local customs and practices. Despite our training and compliance programs, we cannot assure you that our internal control policies and procedures always will protect us from improper or criminal acts committed by our employees or agents. Our continued expansion outside the U.S., including in developing countries, could increase the risk of such violations in the future. Violations of these laws, or allegations of such violations, could disrupt our business, subject us to fines, penalties and restrictions and otherwise result in a material adverse effect on our results of operations or financial condition. All of our recently acquired businesses are subject to our internal policies. However, because our internal policies are more restrictive than some local laws or customs where we operate, we may be at an increased risk for violations while we train our new employees to comply with our internal policies and procedures.

Our business sometimes requires our employees to travel to and work in high security risk countries, which may result in employee injury, repatriation costs or other unforeseen costs.

        Many of our employees often travel to and work in high security risk countries around the world that are undergoing or that may undergo political, social and economic upheavals resulting in war, civil unrest, criminal activity or acts of terrorism. For example, we have had and expect to have significant projects in the Middle East and Africa, including in Afghanistan, Iraq, Libya, Egypt, Saudi Arabia, Qatar and Oman. As a result, we may be subject to costs related to employee injury, repatriation or other unforeseen circumstances. Further, circumstances in these countries could make it difficult or impossible to attract and retain qualified employees. Our inability to attract and retain qualified employees to work in these counties could have a material adverse effect on our operations.

Our business is sensitive to oil and gas prices, and fluctuations in oil and gas prices may negatively affect our business.

        Historically, oil and natural gas prices have been volatile and are subject to fluctuations in response to changes in supply and demand, market uncertainty and a variety of additional factors that are beyond our control. In 2013, approximately 47.2% of our consulting fee revenue was derived from our operations in major oil and gas producing countries in the Middle East and Africa. A significant drop in oil or gas prices could lead to a slowdown in construction in these regions, which could have a material adverse effect on our business, results of operations, financial condition or cash flows.

We depend on government contracts for a significant portion of our consulting fee revenue. Our inability to win profitable government contracts could harm our operations and adversely affect our net earnings.

        In 2013, U.S. federal government contracts and U.S. state, regional and local government contracts contributed approximately 2.9% and 13.6%, respectively, of our consulting fee revenue, and foreign government contracts contributed approximately 35.3% of our consulting fee revenue. Our inability to win profitable government contracts could harm our operations and adversely affect our net earnings. Government contracts are typically awarded through a heavily regulated procurement process. Some government contracts are awarded to multiple competitors, causing increases in overall competition and pricing pressure. In turn, the competition and pricing pressure may require us to make sustained post-award efforts to reduce costs under these contracts. If we are not successful in reducing the amount of costs, our profitability on these contracts may be negatively impacted. Also, some of our federal government contracts require U.S. government security clearances. If we or certain of our personnel were to lose these security clearances, our ability to continue performance of these contracts or to win new contracts requiring such clearances may be negatively impacted.

We depend on long-term government contracts, many of which are funded on an annual basis. If appropriations are not made in subsequent years of a multiple-year contract, we will not realize all of our potential revenue and profit from that project.

        A significant portion of our consulting fee revenue is derived from contracts with federal, state, regional, local and foreign governments. During the years ended December 31, 2013, 2012 and 2011, approximately 51.8%, 40.9% and 40.6%, respectively, of our consulting fee revenue were derived from such contracts.

        Most government contracts are subject to the continuing availability of legislative appropriation. Legislatures typically appropriate funds for a given program on a year-by-year basis, even though contract performance may take more than one year. As a result, at the beginning of a program, the related contract is only partially funded, and additional funding is normally committed only as appropriations are made in each subsequent fiscal year. These appropriations and the timing of payment of appropriated amounts may be influenced by, among other things, the state of the economy, budgetary and other political issues affecting the particular government and its appropriations process, competing priorities for appropriation, the timing and amount of tax receipts and the overall level of government expenditures. If appropriations are not made in subsequent years on government contracts, then we will not realize all of our potential revenue and profit from those contracts.

We depend on contracts that may be terminated by our clients on short notice, which may adversely impact our ability to recognize all of our potential revenue and profit from the project.

        Substantially all of our contracts are subject to termination by the client either at its convenience or upon our default. If one of our clients terminates a contract at its convenience, then we typically are able to recover only costs incurred or committed, settlement expenses and profit on work completed prior to termination, which could prevent us from recognizing all of our potential revenue and profit

16

Table of Contents

from that contract. If one of our clients terminates the contract due to our default, we could be liable for excess costs incurred by the client in re-procuring services from another source, as well as other costs.

Our business is subject to numerous laws, regulations and restrictions, and failure to comply with these laws, regulations and restrictions could subject us to fines, penalties, suspension or debarment.

        Our contracts and operations are subject to various laws and regulations. Prime contracts with various agencies of the U.S. federal government, and subcontracts with other prime contractors, are subject to numerous procurement regulations, including the Federal Acquisition Regulations and the False Claims Act. We could be subject to fines, penalties or debarment, or suspended from receiving additional contracts with all U.S. government agencies if any one agency finds that we are not in compliance with the appropriate regulations. Although a small percentage of our business is from U.S. federal government contracts, suspension or debarment from business with the U.S. federal government could impact other public-sector clients and have a material adverse effect on our financial results.

        Our international business subjects us to numerous U.S. and foreign laws and regulations, including, without limitation, regulations relating to economic sanctions and other trade controls, technology transfer restrictions, repatriation of earnings, exchange controls, the FCPA and the anti-boycott provisions of the U.S. Export Administration Act. Changes in regulations or political environments may affect our ability to conduct business in foreign markets including investment, procurement and repatriation of earnings. Failure by us or our sales representatives or consultants to comply with these laws and regulations could result in certain liabilities and could possibly result in suspension or debarment from government contracts, which could have other repercussions and thus could have a material adverse effect on our financial results.

Our contracts with governmental agencies are subject to audit, which could result in adjustments to reimbursable contract costs or, if we are charged with wrongdoing, possible temporary or permanent suspension from participating in government programs.

        Our books and records are subject to audit by the various governmental agencies we serve and by their representatives. These audits can result in adjustments to reimbursable contract costs and allocated overhead. In addition, if as a result of an audit, we or one of our subsidiaries is charged with wrongdoing or the government agency determines that we or one of our subsidiaries is otherwise no longer eligible for federal contracts, then we or, as applicable, that subsidiary, could be temporarily suspended or, in the event of convictions or civil judgments, could be prohibited from bidding on and receiving future government contracts for a period of time. Furthermore, as a U.S. government contractor, we are subject to an increased risk of investigations, criminal prosecution, civil fraud, whistleblower lawsuits and other legal actions and liabilities, the results of which could have a material adverse effect on our operations.

We submit change orders to our clients for work we perform beyond the scope of some of our contracts. If our clients do not approve these change orders, our net earnings could be adversely impacted.

        We typically submit change orders under some of our contracts for payment for work performed beyond the initial contractual requirements. The clients may not approve or may contest these change orders and we cannot assure you that these claims will be approved in whole, in part or at all. If these claims are not approved, our net earnings could be adversely impacted.

Because our backlog of uncompleted projects under contract or awarded is subject to unexpected adjustments and cancellations, including the amount, if any, of future appropriations by the applicable contracting governmental agency, it may not be indicative of our future revenue and profits.

        At December 31, 2013, our backlog of uncompleted projects under contract or awarded was approximately $1.027 billion. The inability to obtain financing or governmental approvals, changes in economic or market conditions or other unforeseen events, such as terrorist acts or natural disasters, could lead to us not realizing any revenue under some or all of these contracts. We cannot assure you that the backlog attributed to any of our uncompleted projects under contract will be realized as revenue or, if realized, will result in profits.

        Many projects may remain in our backlog for an extended period of time because of the size or long-term nature of the contract. In addition, from time to time projects are scaled back or cancelled. These types of backlog reductions adversely affect the revenue and profit that we ultimately receive. Included in our backlog is the maximum amount of all indefinite delivery/indefinite quantity ("ID/IQ"), or task order, contracts, or a lesser amount if we do not reasonably expect to be issued task orders for the maximum amount of such contracts. A significant amount of our backlog is derived from ID/IQ contracts and we cannot provide any assurance that we will in fact be awarded the maximum amount of such contracts.

Our dependence on subcontractors, partners and specialists could adversely affect our business.

        We rely on third-party subcontractors as well as third-party strategic partners and specialists to complete our projects. To the extent that we cannot engage such subcontractors, partners or specialists or cannot engage them on a competitive basis, our ability to complete a project in a timely fashion or at a profit may be impaired. If we are unable to engage appropriate strategic partners or specialists in some instances, we could lose the ability to win some contracts. In addition, if a subcontractor or specialist is unable to deliver its services according to the negotiated terms for any reason, including the deterioration of its financial condition or over-commitment of its resources, we may be required to purchase the services from another source at a higher price. This may reduce the profit to be realized or result in a loss on a project for which the services were needed.

If our partners fail to perform their contractual obligations on a project, we could be exposed to legal liability, loss of reputation or reduced profits.

        We sometimes enter into joint venture agreements and other contractual arrangements with outside partners to jointly bid on and execute a particular project. The success of these joint projects depends on the satisfactory performance of the contractual obligations of our partners. If any of our partners fails to satisfactorily perform its contractual obligations, we may be required to make additional investments and provide additional services to complete the project. If we are unable to adequately address our partner's performance issues, then our client could terminate the joint project, exposing us to legal liability, loss of reputation or reduced profits.

Our services expose us to significant risks of liability and our insurance policies may not provide adequate coverage.

        Our services involve significant risks of professional and other liabilities that may substantially exceed the fees that we derive from our services. In addition, we sometimes contractually assume liability under indemnification agreements. We cannot predict the magnitude of potential liabilities from the operation of our business.

        We currently maintain comprehensive general liability, umbrella and professional liability insurance policies. Professional liability policies are "claims made" policies. Thus, only claims made during the term of the policy are covered. Additionally, our insurance policies may not protect us against potential

18

Table of Contents

liability due to various exclusions and retentions. Partially or completely uninsured claims, if successful and of significant magnitude, could have a material adverse effect on our business.

The project management and construction claims businesses are highly competitive and if we fail to compete effectively, we may miss new business opportunities or lose existing clients and our revenues and profitability may decline.

        The project management and construction claims industries are highly competitive. We compete for contracts, primarily on the basis of technical capability, with numerous entities, including design or engineering firms, general contractors, other "pure" construction management companies, other claims consulting firms, the "Big Four" and other accounting firms, management consulting firms and other entities. Compared to us, many of these competitors are larger, well-established companies that have broader geographic scope and greater financial and other resources. If we cannot compete effectively with our competitors, or if the costs of competing, including the costs of retaining and hiring professionals, become too expensive, our revenue growth and financial results may differ materially from our expectations.

We have acquired and may continue to acquire businesses as strategic opportunities arise and may be unable to realize the anticipated benefits of those acquisitions, or if we are unable to take advantage of strategic acquisition situations, our ability to expand our business may be slowed or curtailed.

        Over the past 16 years, we have acquired 22 businesses and our strategy is to continue to expand and diversify our operations with additional acquisitions as strategic opportunities arise. If the competition for acquisitions increases, or if the cost of acquiring businesses or assets becomes too expensive, the number of suitable acquisition opportunities may decline, the cost of making an acquisition may increase or we may be forced to agree to less advantageous acquisition terms for the companies that we are able to acquire. Alternatively, at the time an acquisition opportunity presents itself, internal and external pressures (including, but not limited to, borrowing capacity under our credit facilities or the availability of alternative financing), may cause us to be unable to pursue or complete an acquisition. Our ability to grow our business, particularly through acquisitions, may depend on our ability to raise capital by selling equity or debt securities or obtaining additional debt financing. There can be no assurance that we will be able to obtain financing when we need it or on terms acceptable to us. Some of the financial, business and operational risks associated with acquisitions include:

•

Unexpected losses of key personnel or clients of the acquired business;



•

Difficulties arising from the increasing scope, geographic diversity and complexity of our operations;



•

Difficulties in integrating diverse corporate cultures and management styles;



•

Increased costs to improve or coordinate managerial, operational, financial and administrative systems;



•

Dilutive issuances of equity securities;



•

Increased amortization expense of acquired intangible assets;



•

Changes in future market conditions could materially affect the determination of fair value and/or the impairment of goodwill acquired in connection with business combinations may result in future impairment charges;



•

Undisclosed or unknown liabilities associated with the acquired business;



•

Diversion of management's attention from other business concerns; and



•

Adverse effects on existing business relationships with clients.

        In addition, managing the growth of our operations will require us to continually increase and improve our operational, financial and human resources management and our internal systems and controls. If we are unable to manage growth effectively or to successfully integrate acquisitions or if we are unable to grow our business, that could have a material adverse effect on our business.

We may be required to write-off all or a portion of the carrying value of intangibles and goodwill of companies we have acquired.

        At December 31, 2013, we had $24,964,000 of intangible assets and $85,853,000 of goodwill which represent 5.6% and 19.1% of our total assets. Under U.S. generally accepted accounting principles, we are required to test the carrying value of our intangible assets, including goodwill, for impairment at least annually or when events or changes in circumstances indicate the carrying value may not be recoverable. Factors that may be considered a change in circumstances, indicating that the carrying value of our goodwill or other intangible assets may not be recoverable, include a sustained decline in our stock price and market capitalization, reduced future cash flow estimates and slower growth rates in our industry. We may be required to record a significant non-cash impairment charge in our financial statements during the period in which any impairment of our goodwill or other intangible assets is determined, negatively impacting our results of operations and financial condition.

Our effective tax rate may increase or decrease.

        We are subject to income taxes in the U.S. and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are regularly under audit by tax authorities. Although we believe that our tax estimates and tax positions are reasonable, they could be materially affected by many factors including the final outcome of tax audits and related litigation, the introduction of new tax accounting standards, legislation, regulations, and related interpretations, our global mix of earnings, the realizability of deferred tax assets and changes in uncertain tax positions. A significant increase in our effective tax rate could have a material adverse effect on our financial condition and results of operations.

Systems and information technology interruption and breaches in data security could adversely impact our ability to operate and our operating results.

        As a global company, we are heavily reliant on computer, information and communications technology and related systems in order to properly operate. From time to time, we experience system interruptions and delays. In the event we are unable to regularly deploy software and hardware, effectively upgrade our systems and network infrastructure, and take other steps to improve the efficiency and effectiveness of our systems, the operation of such systems could be interrupted or delayed, or our data security could be breached. In addition, our computer and communications systems and operations could be damaged or interrupted by natural disasters, power loss, telecommunications failures, acts of war or terrorism, acts of God, computer viruses, physical or electronic security breaches. Any of these or other events could cause system interruptions, delays, and loss of critical data including private data. While we have taken steps to address these concerns by implementing sophisticated network security and internal control measures, there can be no assurance that a system failure or loss or data security breach will not materially adversely affect our business, financial condition and operating results.

If our internal controls prove to be ineffective, it could impact our business and operating results.

        Our internal control over financial reporting may not prevent or detect misstatements because of the inherent limitations of internal controls or otherwise, including the possibility of human error, the circumvention or overriding of controls or fraud. Even effective internal controls can provide only

20

---

Table of Contents

reasonable assurance with respect to the preparation and fair presentation of financial statements. If we fail to maintain the adequacy of our internal controls, including any failure to implement required new or improved controls, or if we experience difficulties in their implementation, our business and operating results could be harmed and we could fail to meet our financial reporting obligations.

Our use of accounting estimates involves judgment and could impact our financial results.

        The application of generally accepted accounting principles requires us to make estimates and assumptions about certain items and future events that directly affect our reported financial condition. Our most critical accounting estimates are described in Item 7, "Management's Discussion and Analysis of Financial Condition and Results of Operations", under "Critical Accounting Policies." In addition, as discussed in Note 14, "Commitments and Contingencies," we make certain estimates including decisions related to legal proceedings and reserves. These estimates and assumptions involve the use of judgment. As a result, actual financial results may differ.

Risks Related to Ownership of Our Common Stock

The market price for our common stock could be volatile and could decline, resulting in a substantial or complete loss of your investment.

        The stock markets, including the New York Stock Exchange on which our common stock is listed, have experienced significant price and volume fluctuations. As a result, the market price of our common stock could be similarly volatile, and investors in our common stock may experience a decrease in the value of their shares, including decreases unrelated to our operating performance or prospects. The price of our common stock could be subject to wide fluctuations in response to a number of factors, including:

•

Our operating performance and the performance of other similar companies;



•

Actual or anticipated differences in our operating results;



•

Changes in our revenue or earnings estimates or recommendations by securities analysts;



•

Publication of research reports about us or our industry by securities analysts;



•

Additions and departures of key personnel;



•

Speculation in the press or investment community;



•

Actions by institutional stockholders;



•

Changes in accounting principles;



•

Terrorist acts and other events affecting political, economic or civil conditions in one or more foreign countries in which we operate; and



•

General economic and market conditions, including factors unrelated to our performance.

Future sales of our common and preferred stock may depress the price of our common stock.

        As of March 6, 2014, there were 40,168,591 shares of our common stock outstanding. An additional 6,574,156 shares of our common stock may be issued upon the exercise of options held by employees, management and directors. We also have the authority to issue up to 1,000,000 shares of preferred stock upon terms that are determined by our Board of Directors and additional options to purchase 1,366,844 shares of our common stock without stockholder approval. In addition, in 2011, we registered with the SEC for the potential issuance of 20,000,000 common shares and 8,000,000 common shares. These shares may be used for working capital and general corporate purposes, or used in future acquisitions, respectively, subject to the restrictions of our Credit Agreement. During 2013, we issued

21

---

Table of Contents

1,389,769 shares of our common stock in connection with two acquisitions. Sales of a substantial number of these shares in the public market, or factors relating to the terms we may determine for our preferred stock, options or warrants, could decrease the market price of our common stock. In addition, the perception that such sales might occur may cause the market price of our common stock to decline. Future issuances or sales of our common stock could have an adverse effect on the market price of our common stock.

Because we have no current plans to pay cash dividends on our common stock, you may not receive any return on investment unless you sell your common stock for a price greater than that which you paid for it.

        We may retain future earnings, if any, for future operations, expansion and debt repayment and have no current plans to pay any cash dividends. Any decision to declare and pay dividends in the future will be made at the discretion of our Board of Directors and will depend on, among other things, our results of operations, financial condition, cash requirements, contractual restrictions and other factors that our Board of Directors may deem relevant. In addition, our ability to pay dividends may be limited by covenants of any existing and future outstanding indebtedness we or our subsidiaries incur, including our revolving credit agreement. As a result, you may not receive any return on an investment in our common stock unless you sell our common stock for a price greater than that which you paid for it.

We are able to issue shares of preferred stock with greater rights than our common stock.

        Our Board of Directors is authorized to issue one or more series of preferred stock from time to time without any action on the part of our stockholders. Our Board of Directors also has the power, without stockholder approval, to set the terms of any such series of preferred stock that may be issued, including voting rights, dividend rights and preferences over our common stock with respect to dividends and other terms. If we issue preferred stock in the future that has a preference over our common stock with respect to the payment of dividends or other terms, or if we issue preferred stock with voting rights that dilute the voting power of our common stock, the rights of holders of our common stock or the market price of our common stock could be adversely affected.

Provisions in our organizational documents and Delaware law could discourage potential acquisition proposals, could delay or prevent a change in control of the Company that our stockholders may consider favorable and could adversely affect the market value of our common stock.

        Provisions in our organizational documents and Delaware law could discourage potential acquisition proposals, could delay or prevent a change in control of the Company that our stockholders may consider favorable and could adversely affect the market value of our common stock. Our amended and restated certificate of incorporation and amended and restated bylaws include provisions that:

•

Our Board of Directors is expressly authorized to make, alter or repeal our bylaws;



•

Our Board of Directors is divided into three classes of service with staggered three-year terms. This means that only one class of directors will be elected at each annual meeting of stockholders, with the other classes continuing for the remainder of their respective terms;



•

Our Board of Directors is authorized to issue preferred stock without stockholder approval;



•

Only our Board of Directors, our Chairman of the Board, our Chief Executive Officer or the holders of a majority in amount of our capital stock issued and outstanding and entitled to vote may call a special meeting of stockholders; this means that minority stockholders cannot force stockholder consideration of a proposal, including a proposal to replace our Board of Directors, by calling a special meeting of stockholders prior to such time authorized by our Board of

22

Table of Contents

Directors, our Chairman of the Board, our Chief Executive Officer or the holders of a majority in amount of our capital stock issued and outstanding and entitled to vote;

•

Our bylaws require advance notice for stockholder proposals and director nominations;



•

Our bylaws limit the removal of directors and the filling of director vacancies; and



•

We will indemnify officers and directors against losses that may incur in connection with investigations and legal proceedings resulting from their services to us, which may include services in connection with takeover defense measures.

        These provisions may make it more difficult for stockholders to take specific corporate actions and could have the effect of delaying or preventing a change in control of the Company.

        In addition, Section 203 of the Delaware General Corporation Law imposes certain restrictions on mergers and other business combinations between the Company and any holder of 15% or more of our outstanding common stock. This provision is applicable to Hill and may have an anti-takeover effect that may delay, defer or prevent a tender offer or takeover attempt that a stockholder might consider in the stockholder's best interest. In general, Section 203 could delay for three years and impose conditions upon "business combinations" between an "interested shareholder" and Hill, unless prior approval by our Board of Directors is given. The term "business combination" is defined broadly to include mergers, asset sales and other transactions resulting in financial benefit to a stockholder. An "interested shareholder," in general, would be a person who, together with affiliates and associates, owns, or within three years, did own, 15% or more of a corporation's voting stock.

A small group of stockholders own a large quantity of our common stock thereby potentially exerting significant influence over the Company.

        As of December 31, 2013, Irvin E. Richter, David L. Richter and other members of the Richter family beneficially owned approximately 33% of our common stock. This concentration of ownership could significantly influence matters requiring stockholder approval and could delay, deter or prevent a change in control of the Company or other business combinations that might otherwise be beneficial to our other stockholders. Accordingly, this concentration of ownership may impact the market price of our common stock. In addition, the interest of our significant stockholders may not always coincide with the interest of the Company's other stockholders. In deciding how to vote on such matters, they may be influenced by interests that conflict with our other stockholders.

Item 2.    Properties.

        Our executive and operating offices are located at 303 Lippincott Centre, Marlton, New Jersey 08053. We lease all of our office space and do not own any real property. The telephone number at our executive office is (856) 810-6200. In addition to our executive offices, we have approximately 100 operating leases for office facilities throughout the world. Due to acquisition and growth we may have more than one operating lease in the cities in which we are located. Additional space may be required as our business expands geographically, but we believe we will be able to obtain suitable space as needed.

Item 3.    Legal Proceedings.

General Litigation

        M.A. Angeliades, Inc. ("Plaintiff") has filed a complaint with the Supreme Court of New York against the Company and the New York City Department of Design and Construction ("DDC") regarding payment of approximately $8,771,000 for work performed as a subcontractor to the Company plus interest and other costs. The Company has accrued approximately $2,340,000, including interest of $448,000, based on invoices received from Plaintiff who has refused to provide invoices for the additional work that Plaintiff claims to have performed. Until such time as the Company obtains invoices for the additional work and is able to provide those invoices to DDC for reimbursement or there is a full resolution of the litigation, it has no intention of paying Plaintiff. The Company believes that its position is defensible, however, there can be no assurance that it will receive a favorable verdict should this case proceed to trial.

        From time to time, the Company is a defendant or plaintiff in various legal actions which arise in the normal course of business. As such the Company is required to assess the likelihood of any adverse outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of the provision required for these commitments and contingencies, if any, which would be charged to earnings, is made after careful analysis of each matter. The provision may change in the future due to new developments or changes in circumstances. Changes in the provision could increase or decrease the Company's earnings in the period the changes are made. It is the opinion of management, after consultation with legal counsel, that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Item 7.    Management's Discussion and Analysis of Financial Condition and Results of Operations.

Overview

        Our revenue consists of two components: consulting fee revenue ("CFR") and reimbursable expenses. Reimbursable expenses are reflected in equal amounts in both total revenue and total direct expenses. Because these pass-through revenue/costs are subject to significant fluctuation from year to year, we measure the performance of many of our key operating metrics as a percentage of CFR, as we believe that this is a better and more consistent measure of operating performance than total revenue.

        CFR increased $94,487,000, or 22.6%, to $512,085,000 in 2013. CFR for the Project Management segment increased $80,370,000 principally due to increased work in the Middle East, primarily Oman, Qatar and Saudi Arabia. CFR for the Construction Claims segment increased by $14,117,000 due primarily to increased work in the Middle East and Asia/Pacific.

        Cost of services increased $56,483,000, or 23.6%, to $296,055,000 in 2013 as a result of an increase in employees and other direct expenses related to the additional work in the Middle East.

        Gross profit increased $38,004,000, or 21.3%, to $216,030,000 in 2013 due to the increases in CFR. Gross profit as a percent of CFR remained relatively constant at 42.2% in 2013.

        Selling, general and administrative expenses increased $10,793,000, or 6.2%, principally due to the unapplied portion of new staff required for the increase in CFR. As a percentage of CFR, selling, general and administrative expenses decreased to 35.8% in 2013 compared to 41.4% in 2012.

        Operating profit was $32,458,000 in 2013 compared to $5,247,000 in 2012. The increase in operating profit was primarily due to a combination of increased CFR, lower selling, general and administrative expenses as a percentage of CFR resulting from ongoing cost-cutting initiatives and higher utilization rates for professional staff.

        Income tax expense was $6,043,000 for 2013 compared to $13,442,000 for 2012. The change is primarily the result of an increase of $17,707,000 in the valuation allowance against the Company's U.S. deferred tax asset in 2012.

        Net income attributable to Hill was $1,629,000 in 2013 compared to a net loss of ($28,217,000) in 2012. Diluted income per common share was $0.04 in 2013 based upon 39,322,000 diluted common shares outstanding compared to a net loss per diluted common share of ($0.73) in 2012 based upon 38,500,000 diluted common shares outstanding.

        We have open but inactive contracts in Libya. During 2013 and early 2014, we received payments of approximately $9,200,000 from our client, the Libyan Organization for the Development of Administrative Centres ("ODAC"), for work performed prior to March 2011. The remaining accounts receivable balance with ODAC is now $50,800,000. Since the end of the Libyan civil unrest in October 2011, the Company has sought to recover its receivable from ODAC through ongoing negotiations rather than pursue its legal rights for payment under the contracts. The Company believes that this course of action provides the best likelihood for recovery as it could result in completion of and payment on the existing contracts as well as the potential for the award of new contracts. There is at present no agreement, understanding or timetable for further payments of Hill's accounts receivable from ODAC or a return to work on Hill's existing contracts. However, management believes that these payments, along with letters of credit of approximately $14,000,000 posted in our favor by ODAC, were made in good faith and are a positive indication that ODAC intends to satisfy its obligations to Hill. However, the Company cannot predict with certainty when, or if, the remaining accounts receivable will be paid by the Libyan authorities or when work will resume there.

        Despite continuing global economic uncertainty and current limits to financial credit, we remain optimistic about maintaining our current growth strategy to pursue new business development

opportunities, continue to take advantage of organic growth opportunities, continue to pursue acquisitions and strengthen our professional resources. Among other things, our optimism stems from the growth of our backlog at December 31, 2013. Our total backlog is a record $1,027,000,000, an increase of $76,000,000 from September 30, 2013 and $104,000,000 from December 31, 2012. Our 12-month backlog is also a record $394,000,000, an increase of $12,000,000 from September 30, 2013 and $12,000,000 from December 31, 2012. These increases are primarily related to significant new work in Iraq and Saudi Arabia.

Non-GAAP Financial Measures

        Regulation G, conditions for use of Non-Generally Accepted Accounting Principles ("Non-GAAP") financial measures, and other SEC regulations define and prescribe the conditions for use of certain Non-GAAP financial information. Generally, a Non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. We believe earnings before interest, taxes, depreciation and amortization ("EBITDA"), in addition to operating profit, net earnings and other GAAP measures, is a useful indicator of our financial and operating performance and our ability to generate cash flows from operations that are available for taxes and capital expenditures. This measure, however, should be considered in addition to, and not as a substitute or superior to, operating profit, cash flows, or other measures of financial performance prepared in accordance with GAAP. The following table is a reconciliation of EBITDA to the most directly comparable GAAP measure in accordance with SEC Regulation S-K for the years ended December 31, 2013, 2012 and 2011 (in thousands):

Critical Accounting Policies and Estimates

        Our consolidated financial statements were prepared in accordance with U.S. generally accepted accounting principles, which require us to make subjective decisions, assessments and estimates about the effect of matters that are inherently uncertain. As the number of variables and assumptions affecting the judgment increases, such judgments become even more subjective. While we believe our assumptions are reasonable and appropriate, actual results may be materially different than estimated.

Revenue Recognition

        We generate revenue primarily from providing professional services to our clients. Revenue is generally recognized upon the performance of services. In providing these services, we may incur reimbursable expenses, which consist of amounts paid to subcontractors and other third parties as well as travel and other job related expenses that are contractually reimbursable from clients. We will include reimbursable expenses in computing and reporting our total contract revenue as long as we remain responsible to the client for the fulfillment of the contract and for the overall acceptability of all services provided.

Table of Contents

        We earn our revenue from cost-plus, fixed-price and time-and-materials contracts. If estimated total costs on any contract indicate a loss, we charge the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change orders, claims, anticipated losses, and other effects are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. Such revisions could occur at any time and the effects may be material. The majority of our contracts are for work where we bill the client monthly at hourly billing rates. The hourly billing rates are determined by contract terms. For governmental clients, the hourly rates are generally calculated as either (i) a negotiated multiplier of our direct labor costs or (ii) as direct labor costs plus overhead costs plus a negotiated profit percentage. For commercial clients, the hourly rates are generally taken from a standard fee schedule by staff classification or they can be at a negotiated discount from this schedule. In some cases, primarily for foreign work, a fixed monthly staff rate is negotiated rather than an hourly rate. This monthly rate is determined based upon a buildup of direct labor costs plus overhead and profit. We account for these contracts on a time-and-expenses method, recognizing revenue as costs are incurred.

        We account for fixed-price contracts on the "percentage-of-completion" method, wherein revenue is recognized as costs are incurred. Under the percentage-of-completion method for revenue recognition, we estimate the progress towards completion to determine the amount of revenue and profit to be recognized. We generally utilize a cost-to-cost approach in applying the percentage-of-completion method, where revenue is earned in proportion to total costs incurred divided by total costs expected to be incurred.

        Under the percentage-of-completion method, recognition of profit is dependent upon the accuracy of estimates. We have a history of making reasonably dependable estimates of contract revenue, the extent of progress towards completion and contract completion costs on our long-term construction management contracts. However, due to uncertainties inherent in the estimation process, it is possible that actual completion costs may vary from estimates.

Allowance for Doubtful Accounts

        We make ongoing estimates relating to the collectibility of our accounts receivable and maintain an allowance for estimated losses resulting from the inability of our clients to make required payments. Estimates used in determining accounts receivable allowances are based on specific client account reviews and historical experience of credit losses. We also apply judgment including assessments about changes in economic conditions, concentration of receivables among clients and industries, recent write-off trends, rates of bankruptcy, and credit quality of specific clients. Unanticipated changes in the financial condition of clients, the resolution of various disputes, or significant changes in the economy could impact the reserves required. At December 31, 2013 and 2012, the allowance for doubtful accounts was $9,530,000 and $10,268,000, respectively.

Goodwill and Other Intangible Assets

        Goodwill is tested annually for impairment in our third fiscal quarter or more frequently if events or circumstances indicate that there may be an impairment. We have determined that we have two reporting units, the Project Management unit and the Construction Claims unit. We made that determination based on the similarity of the services provided, the methodologies in delivering our services and the similarity of the client base in each of these units. To determine the fair value of our reporting units, we use the market approach and the income approach, weighting the results of each approach.

        Under the market approach, we determine fair value using the public company method and the quoted price method. We utilized a control premium of 30% to arrive at the preliminary fair value for

31

Table of Contents

each reporting unit, and we applied a weighting of 20% to the preliminary fair value determined by using the public company method. The quoted price method is based upon the market value of the transactions of minority interests in the publicly-traded shares of the Company. We utilized a control premium of 30% to arrive at the preliminary fair value for each reporting unit, and we applied a weighting of 50% to the preliminary fair value determined using the quoted price method.

        Our calculation under the income approach utilizes our internal forecasts. In the income approach (that is, the discounted cash flow method), the projected cash flows reflect the cash flows subsequent to the sale of the reporting unit pursuant to the guidance in ASC 350 and ASC 820. Consistent with applicable literature, we include in projected cash flows any expected improvements in cash flows or other changes that, in our view, a market participant would consider and be willing to pay for (but we exclude any buyer- or entity-specific synergies). The projections are developed by us and are based upon cash flows that maximize reporting unit value by taking into account improvements that controlling-interest holders can make, but minority interest holders cannot make. These improvements include: increasing revenues, reducing operating costs, or reducing non-operating costs such as taxes. The owners of the enterprise may also increase enterprise value by reducing risk; for example, by diversifying the business, improving access to capital, increasing the certainty of cash flows, or optimizing the capital structure.

        We considered the factors listed above when developing the cash flows to support the income approach. Recognizing that due to elements of control incorporated into our reporting units' forecasts, we applied no control premium to our conclusion of value indicated by the discounted cash flows. In determining fair value, we applied a weighting of 30% to the preliminary fair value determined using the income approach.

        With regard to weighting the conclusions rendered by the approaches utilized, we believe that the quoted price method provides the most reliable indication of value (that is, a Level 1 input); therefore, we placed the greatest emphasis upon this method assigning a 50% weighting. We also determined that the value using the discounted cash flow method (to which we assigned a 30% weighting) provided a more reliable indication of value than the public company method (to which we assigned a 20% weighting) with the relative levels of reliability contributing to the weighting accorded to each approach.

        Application of the goodwill impairment test requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for each reporting unit, the period over which cash flows will occur, and determination of the weighted average cost of capital, among other things. Based on the valuation as of July 1, 2013, the fair values of the Project Management unit and the Construction Claims unit substantially exceeded their carrying values. Changes in these estimates and assumptions could materially affect our determination of fair value and/or goodwill impairment for each reporting unit. Changes in future market conditions, our business strategy, or other factors could impact upon the future values of Hill's reporting units, which could result in future impairment charges.

        We amortize other intangible assets over their estimated useful lives and review the long-lived assets for impairment whenever events or changes in circumstances indicate that the related carrying amounts may not be recoverable. Determining whether impairment has occurred typically requires various estimates and assumptions, including determining which cash flows are directly related to the potentially impaired asset, the useful life over which cash flows will occur, their amount and the asset's residual value, if any. In turn, measurement of an impairment loss requires a determination of fair value, which is based on the best information available. We use internal discounted cash flow estimates, quoted market prices when available and independent appraisals, as appropriate, to determine fair value. We derive the required cash flow estimates from our historical experience and our internal business plans and apply an appropriate discount rate.

Income Taxes

        We make judgments and interpretations based on enacted tax laws, published tax guidance, as well as estimates of future earnings. These judgments and interpretations affect the provision for income taxes, deferred tax assets and liabilities and the valuation allowance. We evaluate the deferred tax assets to determine on the basis of objective factors whether the net assets will be realized through future years' taxable income. In the event that actual results differ from these estimates and assessments, additional valuation allowances may be required.

        We will recognize a tax benefit in the financial statements for an uncertain tax position only if management's assessment is that the position is "more likely than not" (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term "tax position" refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods.

Stock Options

        We recognize compensation expense for all stock-based awards. These awards have included stock options and restricted stock grants. While fair value may be readily determinable for awards of stock, market quotes are not available for long-term, nontransferable stock options because these instruments are not traded. We currently use the Black-Scholes option pricing model to estimate the fair value of options. Option valuation models require the input of highly subjective assumptions, including but not limited to stock price volatility, expected life and stock option exercise behavior.

Contingencies

        Estimates are inherent in the assessment of our exposure to insurance claims that fall below policy deductibles and to litigation and other legal claims and contingencies, as well as in determining our liabilities for incurred but not reported insurance claims. Significant judgments by us and reliance on third-party experts are utilized in determining probable and/or reasonably estimable amounts to be recorded or disclosed in our financial statements. The results of any changes in accounting estimates are reflected in the financial statements of the period in which the changes are determined. We do not believe that material changes to these estimates are reasonably likely to occur.

Results of Operations

Year Ended December 31, 2013 Compared to
Year Ended December 31, 2012

Consulting Fee Revenue ("CFR")

        The increase in CFR for 2013 over 2012 was substantially all organic and was primarily due to increased work in the Middle East.

        During 2013, Project Management CFR consisted of a $76,032,000 increase in foreign projects and an increase of $4,338,000 in domestic projects. The increase in foreign Project Management CFR included an increase of $47,826,000 in Oman, $12,321,000 in Qatar, $7,634,000 in Saudi Arabia, $5,478,000 in Iraq and $5,194,000 in Afghanistan. These increases were partially offset by a decrease of $8,930,000 in Spain. The increase in domestic Project Management CFR was due primarily to increases in our Northeast and Mid-Atlantic regions.

33

---

Table of Contents

        The increase in Construction Claims CFR was comprised of an organic increase of 11.0% and a 2.4% increase from the acquisition of Binnington Copeland & Associates ("BCA") in May 2013. The organic increase was primarily due to increases in Middle East and Asia/Pacific, partially offset by a decrease in the United Kingdom.

Reimbursable Expenses

        Reimbursable expenses consist of amounts paid to subcontractors and other third parties, and travel and other job-related expenses that are contractually reimbursable from clients. These items are reflected as separate line items in both our revenue and cost of services captions in our consolidated statements of operations. The increase in Construction Claims reimbursable expenses was due primarily to increases in the Middle East and Asia/Pacific due to subcontractors and other reimbursable expenses associated with the increased work volume.

Cost of Services

        Cost of services consists of labor expenses for time charged directly to contracts and non-reimbursable job-related travel and out-of-pocket expenses.

        The increase in Project Management cost of services is primarily due to increases in the Middle East in support of increased work.

        The increase in the cost of services for Construction Claims was due primarily to increases in direct cost in the Middle East, Asia/Pacific and South Africa (due to the BCA acquisition), partially offset by decreases in the United Kingdom.

Gross Profit

34

---

Table of Contents

        The increase in Project Management gross profit included an increase of $26,421,000 from international operations, primarily due to increases from the Middle East, principally Oman, Qatar, Saudi Arabia, Iraq and Afghanistan.

        The increase in Construction Claims gross profit was driven by an increase of $4,245,000 in the Middle East, $3,430,000 in Asia/Pacific and $1,571,000 in South Africa, partially offset by a decrease of $1,357,000 in the United Kingdom.

        The overall gross profit percentage declined slightly due to an increase in the mix of work towards the Project Management group which generally has lower gross margin percentages than the Construction Claims group.

Selling, General and Administrative ("SG&A") Expenses

        As a percentage of CFR, SG&A expense decreased to 35.8% in 2013 compared to 41.4% in 2012.

        The significant components of the change in SG&A are as follows:

•

An increase of $8,279,000 in unapplied labor primarily in the Middle East due to an increase in staff required for the new work. Unapplied labor, which increased 16.4% over the prior year compared to a 22.6% increase in CFR, represents the labor cost of operating staff for non-billable tasks. This represents improved utilization of billable staff over the prior year;



•

An increase of $5,668,000 in indirect labor including $2,500,000 in staff termination costs primarily in Spain and Brazil where staff was reduced as several projects ended;



•

An increase in administrative travel of $1,391,000 in support of expanded international operations;



•

An increase of $1,163,000 in professional fees due to statutory, audit and tax filings due to increased international operations;



•

An increase of $1,000,000 due to a 2012 credit to indirect expenses for the reversal of an unachieved earn-out liability which was recorded as part of the acquisition of TRS Consultants in December 2009;



•

An increase of $792,000 in information technology related costs in support of increased staff and expanded global operations;



•

An increase of $719,000 in bad debt expense for reserves placed primarily in the domestic Project Management Group;



•

A decrease of $7,693,000 consisting of a $3,693,000 reversal in 2013 of a reserve for potential employment tax liabilities that was originally established in 2012 in the amount of $4,000,000; and



•

A decrease of $1,446,000 in amortization expense due to the full amortization of the shorter-lived intangible assets of companies we acquired over the last several years.

Operating Profit:

        The increase in Project Management operating profit included an increase of $24,094,000 in the Middle East, primarily Oman, Qatar, Saudi Arabia, Iraq and Afghanistan.

        The increase in Construction Claims operating profit was primarily due to increases of $2,023,000 in the Middle East and $3,304,000 in Asia/Pacific, partially offset by a decrease of $1,020,000 in the United Kingdom.

        Corporate expenses increased $2,298,000 primarily due to increases in indirect labor, stock compensation, travel cost, information technology and depreciation in support of expanded operations overseas.

Interest and related financing fees, net

        Interest and related financing fees increased $4,714,000 to $22,864,000 in 2013 as compared with $18,150,000 in 2012, primarily due to higher levels of debt outstanding and higher interest rates. Included in interest expense in 2013 is a non-cash charge of $7,954,000 compared to $1,520,000 in 2012 attributable to the accretion of the Term Loan.

Income Taxes

        In 2013, the income tax expense was $6,043,000 compared to an income tax expense of $13,442,000 in 2012. The effective income tax expense rates for 2013 and 2012 were 63.0% and (104.2%), respectively. The increase in the Company's effective tax rate during the year was primarily a result of recording a valuation allowance on the net U.S. deferred tax asset of $17,700,000 in 2012 with a consolidated pre-tax loss. In 2013, the Company required an increase in the valuation allowance related to the increase in the net U.S. deferred tax asset while generating consolidated pre-tax income.

        The valuation allowance primarily relates to the U.S. federal and state net operating losses of $63,365,000 and $66,472,000, respectively. The losses were generated in fiscal years 2010 through 2013. The primary reason for recording the valuation allowance was due to management's belief that it is more likely than not that the Company will not be able to utilize its U.S. deferred tax assets in the foreseeable future.

        In 2013, several items materially affected the Company's effective tax rate. The Company realized a net benefit of $2,314,000 primarily from the reversal of prior year's uncertain tax positions based on management's assessment that these items were effectively settled with the appropriate foreign tax authorities. An income tax expense of $386,000 resulted from adjustments to agree the 2012 book amount to the actual amounts reported on the tax returns in foreign jurisdictions. In addition, the Company recognized higher foreign withholding taxes in 2013 which were partially offset by the true up of income tax accounts in foreign jurisdictions.

Table of Contents

        Several items materially affected the Company's effective tax rate during 2012. The Company realized a benefit from the reversal of prior year's uncertain tax position amounting to $350,000 due to the expiration of the statute of limitations upon filing of certain income tax returns in a foreign jurisdiction. An income tax benefit of $666,000 resulted from adjustments to agree the 2011 book amount to the actual amounts reported on the tax returns, primarily in foreign jurisdictions. In addition, the Company recognized an income tax expense related to withholding tax in the amount of $573,000 primarily related to foreign operations and an income tax expense of $804,000 related to potential prior year tax assessments of certain foreign subsidiaries.

Net Earnings Attributable to Hill

        The net earnings attributable to Hill International, Inc. for 2013 was $1,629,000, or $0.04 per diluted common share, based on 39,322,000 diluted common shares outstanding, as compared to a net loss for 2012 of ($28,217,000), or ($0.73) per diluted common share based upon 38,500,000 diluted common shares outstanding.

Year Ended December 31, 2012 Compared to
Year Ended December 31, 2011

Consulting Fee Revenue ("CFR")

        The increase in CFR for 2012 over 2011 was comprised of an organic increase of 2.7% primarily due to increased work in the Middle East and an increase of 1.9% from the acquisition of Engineering S.A. in Brazil.

        During 2012, Project Management CFR included an organic increase of 4.7% primarily from the Middle East plus an increase of 2.7% due to the acquisition of Engineering S.A. The increase in Project Management CFR consisted of a $19,677,000 increase in foreign projects and an increase of $1,768,000 in domestic projects. The increase in foreign Project Management CFR included an increase of $16,815,000 in Saudi Arabia, $4,638,000 in Egypt and $4,339,000 in Afghanistan. These increases were partially offset by decreases of $8,208,000 in Libya where work was suspended in February 2011 due to political unrest and $4,327,000 in Spain. The increase in domestic Project Management CFR was due primarily to increases in our Mid-Atlantic and Western regions.

        The decrease in Construction Claims CFR was all organic and primarily resulted from decreases in Australia, Europe and the Middle East where several large assignments were completed, partially offset by increases in the United Kingdom and the United States.

Reimbursable Expenses

37

---

Table of Contents

        Reimbursable expenses consist of amounts paid to subcontractors and other third parties, and travel and other job-related expenses that are contractually reimbursable from clients. These items are reflected as separate line items in both our revenue and cost of services captions in our consolidated statements of operations. The decrease in Project Management reimbursable expenses was due primarily to decreased use of subcontractors of $41,260,000 primarily in our Northeast region.

Cost of Services

        Cost of services consists of labor expenses for time charged directly to contracts and non-reimbursable job-related travel and out-of-pocket expenses. The increase in Project Management cost of services is primarily due to increases in Saudi Arabia, Afghanistan, Egypt and our U.S. Mid-Atlantic and Western regions in support of the increased revenue in those areas and due to the acquisition of Engineering S.A., partially offset by decreases in Libya and Spain.

        The decrease in the cost of services for Construction Claims was due primarily to decreases in direct cost in Australia, the Middle East and Europe, partially offset by increases in the United Kingdom and the United States.

Gross Profit

        The increase in Project Management gross profit included an increase of $5,971,000 from international operations including increases of $8,885,000 from the Middle East, primarily Saudi Arabia and Afghanistan, $3,197,000 from Brazil and $2,926,000 from Egypt, partially offset by decreases of $4,636,000 from Libya and $3,061,000 from Spain.

        The decrease in Construction Claims gross profit was driven by a decrease of $2,412,000 from Australia where some large assignments were completed, partially offset by an increase in $1,801,000 from the United Kingdom.

Selling, General and Administrative ("SG&A") Expenses

38

---

Table of Contents

        The decrease in SG&A included decreases of $7,523,000, partially offset by an increase of $4,990,000 from Engineering S.A. which was acquired in February 2011.

        The significant components of the change in SG&A are as follows:

•

An increase of $4,000,000 for a reserve for potential employment tax liabilities for certain foreign subsidiaries;



•

A decrease in unapplied and indirect labor expense of $140,000 including a decrease of $1,275,000 due to cost-cutting initiatives, partially offset by an increase of $1,135,000 at Engineering S.A.;



•

A decrease of $2,556,000 in amortization expense due to the full amortization of the shorter-lived intangible assets of companies we acquired over the last several years;



•

A decrease of $1,384,000 in administrative travel due to cost-cutting initiatives, $454,000 of which was attributable to Engineering S.A.;



•

A credit of $1,000,000 to indirect expenses for the reversal of an unachieved earn-out liability which was recorded as part of the acquisition of TRS Consultants in December 2009;



•

A decrease of $792,000 in rent expense due to the early termination of a northern New Jersey office lease in early 2011, a temporary overlapping of rental cost in the United Kingdom during an office relocation during the first quarter of 2011 and to lower office space expenses in 2012 due to renegotiation of various leases during 2012; and



•

A decrease in legal fees of $767,000.

Operating Profit (Loss):

        The increase in Project Management operating profit primarily included an increase of $7,381,000 in the Middle East, primarily Saudi Arabia and Afghanistan, $5,204,000 in the United States and $1,875,000 in Egypt. The increases were partially offset by a decrease in operating profit of $4,869,000 in Libya and $2,956,000 in Romania.

        The decrease in Construction Claims operating profit was primarily due to a decrease of $3,626,000 in Australia and $1,417,000 in the Middle East, partially offset by an increase of $2,735,000 in the United Kingdom.

        Corporate expenses decreased $5,113,000 primarily due to decreases of $1,675,000 in indirect labor and travel expenses as a result of cost-cutting initiatives, a reserve of $1,600,000 in 2011 related to a Saudi Arabian joint venture and a decrease of $1,004,000 in legal fees.

Table of Contents

Interest and related financing fees, net

        Interest and related financing fees, net increased $10,888,000 to $18,150,000 in 2012 as compared with $7,262,000 in 2011, primarily due to higher levels of debt outstanding and higher interest rates, including forbearance agreement fees, default fees, amended Credit Agreement fees, refinancing fees and related legal and advisory fees amounting to $10,775,000 for 2012 compared to $1,076,000 in 2011.

Income Taxes

        In 2012, the income tax expense was $13,442,000 compared to an income tax benefit of ($6,186,000) in 2011. The effective income tax expense rates for 2012 and 2011 were (104.2%) and 55.6%, respectively. The change in the Company's effective tax rate during the year was primarily a result of recording a valuation allowance on the net U.S. deferred tax asset of $17,700,000.

        The valuation allowance primarily relates to the U.S. federal and state net operating losses of $38,400,000 and $41,600,000, respectively. The losses were generated in fiscal years 2010 through 2012. The primary reason for recording the valuation allowance was due to the inability of the Company's majority owned subsidiary, HillStone International, LLC to finalize the contracts that were projected to commence in 2012. In 2011 the Company recognized an income tax benefit of $6,932,000 related to net operating losses from U.S. operations.

        In addition, several items materially affected the Company's effective tax rate during 2012. The Company realized a benefit from the reversal of prior year's uncertain tax position amounting to $350,000 due to the expiration of the statute of limitations upon filing of certain income tax returns in a foreign jurisdiction. An income tax benefit of $666,000 resulted from adjustments to agree the 2011 book amount to the actual amounts reported on the tax returns, primarily in foreign jurisdictions. In addition, the Company recognized an income tax expense related to withholding tax in the amount of $573,000 primarily related to foreign operations and an income tax expense of $804,000 related to potential prior year tax assessments of certain foreign subsidiaries.

        In 2011, four items materially affected the Company's effective tax rate. The Company realized substantial benefits from the reversal of a prior year's uncertain tax position amounting to $1,515,000 due to the expiration of the statute of limitations upon the filing of certain income tax returns and the favorable resolution of a Kazakhstan withholding tax issue. An income tax benefit of $347,000 resulted from adjustments to agree the 2010 book amount to the actual amounts reported on the tax returns, primarily related to foreign operations. In addition, a tax benefit was recognized in the amount of $18,000 representing the tax effect on unrealized foreign exchange losses generated in the United Kingdom which are included as a deduction on the local tax returns. These benefits were offset by an increase in the reserves for uncertain tax positions of $609,000, related primarily to uncertain tax positions of foreign operations. Excluding these items our effective tax rate would have been 44.5% in 2011.

Net Loss Attributable to Hill

        The net loss attributable to Hill International, Inc. for 2012 was ($28,217,000), or ($0.73) per diluted common share based on 38,500,000 diluted common shares outstanding, as compared to a net loss for 2011 of ($6,017,000), or ($0.16) per diluted common share based upon 38,414,000 diluted common shares outstanding.

Liquidity and Capital Resources

        As a result of the worldwide financial situation in recent years as well as the political unrest in Libya, we have had to rely more heavily on borrowings under our various credit facilities to provide funding for our operations. On May 23, 2013, the Company entered into a Fourth Amendment to our

40

---

Table of Contents

Credit Agreement which permitted the Company to enter into an agreement with Qatar National Bank for the issuance of letters of credit ("LCs") not to exceed $17,000,000, increased the limit on LCs available to the Company's foreign subsidiaries who are not loan parties from $4,000,000 to $11,800,000 and permits the Company to provide up to $20,000,000 as cash collateral for letters of credit and performance bonds. On the same day in May 2013, the Company entered into a First Amendment to the Term Loan Agreement. The First Amendment contains identical provisions as those in the Fourth Amendment to Credit Agreement. See Note 9 to our consolidated financial statements for a description of our credit facilities and Term Loan. At December 31, 2013, our primary sources of liquidity consisted of $30,381,000 of cash and cash equivalents, of which $2,573,000 was on deposit in the U.S. and $27,808,000 was on deposit in foreign locations, and $15,552,000 of available borrowing capacity under our various credit facilities. Approximately $14,000,000 of the cash on deposit in foreign locations is required for working capital needs in those countries and the currency limitations related to Libyan dinars. We believe that we have sufficient liquidity to support the reasonably anticipated cash needs of our operations over the next year. Significant unforeseen events, such as termination or cancellation of major contracts, could adversely affect our liquidity and results of operations. If market opportunities exist, we may choose to undertake financing actions to further enhance our liquidity, which could include obtaining new bank debt or raising funds through capital market transactions; however, our ability to borrow additional funds or obtain letters of credit is limited by the terms of our Credit Agreement.

Uncertainties With Respect to Operations in Libya

        We have open but inactive contracts in Libya. Due to the political unrest which commenced in February 2011, we suspended our operations in and demobilized substantially all of our personnel from Libya.

        During the past several months, the Company's accounts receivable related to the work performed prior to March 2011 pursuant to contracts with the Libyan government was reduced by approximately $3,100,000. The reduction consisted of a cash payment by the Libyan Organization for the Development of Administrative Centres ("ODAC") of approximately 3,000,000 Libyan dinars ("LYD") ($2,400,000) that was made directly to Hill and a cash payment of approximately LYD 800,000 ($700,000) that was made by ODAC to the Libyan tax authorities on Hill's behalf. At December 31, 2013, the remaining accounts receivable outstanding amounted to approximately $57,000,000.

        During February 2014, the Company received additional payments of approximately $6,100,000 consisting of approximately 200,000 pounds sterling ($300,000), approximately LYD 2,100,000 ($1,700,000) and $4,100,000 in U.S. dollars.

        In connection with the work performed in Libya, our consolidated financial statements for the years ended December 31, 2013, 2012 and 2011 included the following amounts; we have also reflected the February 2014 collections:

        The LYD 3,000,000 cash payment made in 2013 directly to Hill is not freely convertible into other currencies. As a result, this cash remains in Hill's Libyan bank account. Since the end of the Libyan civil unrest in October 2011, the Company has sought to recover its receivable from ODAC through ongoing negotiations rather than pursue its legal rights for payment under the contracts. The Company believes that this course of action provides the best likelihood for recovery as it could result in completion of and payment on the existing contracts as well as the potential for the award of new

41

Table of Contents

contracts. There is at present no agreement, understanding or timetable for further payments of Hill's accounts receivable from ODAC or a return to work on Hill's existing contracts. However, management believes that these payments, along with letters of credit of approximately $14,000,000 posted in our favor by ODAC, were made in good faith and are a positive indication that ODAC intends to satisfy its obligations to Hill. However, the Company cannot predict with certainty when, or if, the remaining accounts receivable will be paid by the Libyan authorities or when work will resume there. In the event that we do not realize any further payments, there could be a significant adverse impact on our consolidated results of operations and consolidated financial position. See Note 4 to the consolidated financial statements.

Additional Capital Requirements

        On February 28, 2011, our subsidiary, Hill International (Spain), S.A. ("Hill Spain"), acquired an indirect 60% interest in Engineering S.A. ("ESA"), a firm located in Brazil, for cash amounting to 22,200,000 Brazilian Reais ("BR") (approximately $13,392,000 on that date). Minimum additional payments were paid on April 30, 2012 and 2013 in the amount of BR6,624,000 (approximately $3,508,000) and BR11,372,000 (approximately $5,095,000). Under certain circumstances, we may be required to pay BR5,000,000 (approximately $3,016,000) in addition to the minimum payments.

        ESA's shareholders entered into an agreement whereby the minority shareholders have a right to compel ("ESA Put Option") Hill Spain to purchase any or all of their shares during the period from February 28, 2014 to February 28, 2021. Hill Spain also has the right to compel ("ESA Call Option") the minority shareholders to sell any or all of their shares during the same time period. The purchase price for such shares shall be seven times the earnings before interest and taxes for ESA's most recently ended fiscal year, net of any financial debt plus excess cash multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of purchase, but in the event the ESA Call Option is exercised by Hill Spain, the purchase price shall be increased by five percent. The ESA Put Option and the ESA Call Option must be made within three months after the audited financial statements of ESA have been completed.

Sources of Additional Capital

        We have an effective registration statement on Form S-3 on file with the U.S. Securities and Exchange Commission (the "SEC") which registered 20,000,000 shares of our common stock for issuance and sale by us at various times in the future. The proceeds, if any, will be used for working capital and general corporate purposes, subject to the restrictions of our amended Credit Agreement. We cannot predict the amount of proceeds from those future sales, if any, or whether there will be a market for our common stock at the time of any such offering or offerings to the public.

        In addition, we have an effective registration statement on Form S-4 on file with the SEC which registered 8,000,000 shares of our common stock for use in future acquisitions. During 2013, we issued 1,389,769 shares in connection with our acquisitions of BCA and CPI. We will issue additional shares of our common stock in connection with certain additional consideration and contingent consideration for those two companies. However, we cannot predict whether, in the future, we will offer these shares to potential sellers of businesses or assets we might consider acquiring or whether these shares will be acceptable as consideration by any potential sellers.

        We cannot provide any assurance that any other sources of financing will be available, or if available, that the financing will be on terms acceptable to us.

Cash Flow Activity During the Year Ended December 31, 2013

        For the year ended December 31, 2013, our cash and cash equivalents increased by $13,665,000 to $30,381,000. This compares to a net decrease in cash and cash equivalents of $1,208,000 during the

42

Table of Contents

prior year. Cash provided by operations was $21,433,000, cash used in investing activities was $14,826,000 and cash provided by financing activities was $15,961,000. We also experienced a decrease in cash of $8,903,000 from the effect of foreign currency exchange rate fluctuations.

Operating Activities

        Our operations generated cash of $21,433,000 in 2013. This compares to cash used of ($6,471,000) in 2012 and ($10,470,000) in 2011. We had net income in 2013 amounting to $3,551,000, a net loss of ($26,345,000) in 2012 and a net loss of ($4,935,000) in 2011. Depreciation and amortization was $10,756,000 in 2013 compared to $12,430,000 in 2012 and $15,640,000 in 2011; the decrease in this category is due to the full amortization of the shorter-lived intangible assets of companies which we acquired over the last several years. We had deferred tax benefit of ($2,171,000) in 2013 primarily due to several minor temporary differences in foreign jurisdictions.

        Cash held in restricted accounts as collateral for the issuance of performance and advance payment bonds and letters of credit at December 31, 2013 and 2012 were $18,506,000 and $21,226,000, respectively.

        Average days sales outstanding ("DSO") at December 31, 2013 was 126 days compared to 130 days at December 31, 2012 and 134 days at December 31, 2011. DSO is a measure of our ability to collect our accounts receivable and is calculated by dividing the total of the period-end billed accounts receivable balance by average daily revenue (i.e., revenue for the quarter divided by 90 days). The decrease in DSO in 2013 was because the increase in our revenue, due to the ramp-up on new work in the Middle East, outpaced the growth in our accounts receivable. The overall level of DSO continues to be affected by the receivable due from the Libyan Organization for the Development of Administrative Centres ("ODAC") which was approximately $57,000,000 at December 31, 2013. This situation has had a detrimental effect on our operating cash flows over the last two years, and we have had to rely on borrowings under our Credit Agreement and Term Loan to support our operations. Excluding the ODAC receivable, the DSO would have been 91 days at December 31, 2013, 90 days at December 31, 2012 and 93 days at December 31, 2011. Also, the age of our receivables is adversely affected by the timing of payments from our clients in Europe, Africa (other than Libya) and the Middle East, which have historically been slower than payments from clients in other geographic regions of the Company's operations.

        Although we continually monitor our accounts receivable, we manage our operating cash flows by managing the working capital accounts in total, rather than by individual elements. The primary elements of our working capital are accounts receivable, prepaid and other current assets, accounts payable and deferred revenue. Accounts receivable consist of billing to our clients for our consulting fees and other job-related costs. Prepaid expenses and other current assets consist of prepayments for various selling, general and administrative costs, such as insurance, rent, maintenance, etc. Accounts payable consist of obligations to third parties relating primarily to costs incurred for specific engagements, including pass-through costs such as subcontractor costs. Deferred revenue consists of payments received from clients in advance of work performed.

        From year to year, the components of our working capital accounts may reflect significant changes. The changes are due primarily to the timing of cash receipts and payments with our working capital accounts combined with increases in our receivables and payables relative to the increase in our overall business, as well as our acquisition activity.

Investing Activities

        Net cash used in investing activities was $14,826,000. We used $12,062,000 to pay the liability for the Hill Spain equity interest and $3,764,000 to purchase computers, office equipment, furniture and

43

Table of Contents

fixtures. We received $964,000 from our acquisitions of Binnington Copeland & Associates and Collaborative Partners, Inc. which were acquired using shares of our common stock.

Financing Activities

        We received $21,084,000 from borrowings under our Credit Agreement. We also received $158,000 from the exercise of stock options and purchases under our Employee Stock Purchase Plan. We made payments on notes payable related to the acquisition of Engineering S.A. amounted to $5,095,000. Payments on other notes payable amounted to $167,000. Due to banks decreased $19,000 due to a lower level of payments which were disbursed but not immediately funded by the bank.

Recent Accounting Pronouncements

        In February 2013, the Financial Accounting Standards Board ("FASB") issued ASU No. 2013-2, which amends the Comprehensive Income Topic of the ASC. The ASU requires companies to report either on the income statement or disclose in the footnotes to the financial statement the effects on earnings from items that are reclassified out of the category of shareholder equity called accumulated other comprehensive income. The adjustments will consist of amounts from the fiscal period covered by the financial statements. Companies will also have to make cross references to other disclosures required in U.S. GAAP for other line items used to adjust earnings. The FASB wants this requirement applied to amounts that are initially transferred to another balance sheet item before being entered as an adjustment to earnings. The ASU was effective for interim and annual periods commencing after December 15, 2012. The Company adopted the ASU effective January 1, 2013. Adoption of the ASU did not affect the Company's consolidated results of operations, financial condition or liquidity.

Quarterly Fluctuations

        Our operating results vary from period to period as a result of the timing of projects and assignments. We do not believe that our business is seasonal.

Inflation

        Although we are subject to fluctuations in the local currencies of the counties in which we operate, we do not believe that inflation will have a significant effect on our results of operations or our financial position.

Off-Balance Sheet Arrangements

Table of Contents

Contractual Obligations

Item 7A.    Quantitative and Qualitative Disclosures About Market Risk

        We are exposed to risks associated with foreign currency fluctuations and changes in interest rates.

Foreign Exchange Rates

        We are exposed to foreign currency exchange rate risk resulting from our operations outside of the U.S. which are denominated in British pounds sterling, Euros, U.A.E. dirhams, Omani Rial, Saudi Riyal, Brazilian Reais, Libyan dinars, Polish Zloty, Australian dollars as well as other currencies. We do not comprehensively hedge our exposure to currency rate changes; however, we limit exposure to foreign currency fluctuations in most of our contracts through provisions that require client payments to be in currencies corresponding to the currency in which costs are incurred. As a result, we currently do not hedge foreign currency cash flows for contract work performed, although we may do so in the future. The functional currency of our significant foreign operations is the local currency.

Interest Rates

        All of our borrowings under our revolving credit facilities bear interest at variable rates. If market interest rates had changed by 100 basis points, interest expense and our cash flows would have changed by $465,000 and $281,000, respectively.

HILL INTERNATIONAL, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1—The Company

        Hill International, Inc. ("Hill" or the "Company") is a professional services firm that provides program management, project management, construction management, construction claims and other consulting services primarily to the buildings, transportation, environmental, energy and industrial markets worldwide. Hill's clients include the U.S. federal government, U.S. state and local governments, foreign governments and the private sector. The Company is organized into two key operating divisions: the Project Management Group and the Construction Claims Group.

Note 2—Summary of Significant Accounting Policies

(a)   Basis of Presentation

        The accompanying consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States. The consolidated financial statements include the accounts of Hill International, Inc. and its majority owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

(b)   Use of Estimates

        The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates. The estimates affecting the consolidated financial statements that are particularly significant include revenue recognition, allocation of purchase price to acquired intangibles and goodwill, recoverability of long-lived assets, income taxes, allowance for doubtful accounts and commitments and contingencies.

(c)   Foreign Currency Translations and Transactions

        Assets and liabilities of all foreign operations are translated at year-end rates of exchange, and the statements of operations are translated at the average rates of exchange for the year. Gains or losses resulting from translating foreign currency financial statements are accumulated in a separate component of stockholders' equity entitled accumulated other comprehensive loss until the entity is sold or substantially liquidated. Gains or losses from foreign currency transactions (transactions denominated in a currency other than the entity's local currency) are reflected in selling, general, and administrative expenses in the consolidated statement of operations.

(d)   Fair Value of Financial Instruments

        The fair value of financial instruments, which primarily consists of cash and cash equivalents, accounts receivable, accounts payable and due to bank, approximates carrying value due to the short-term nature of the instruments. The carrying value of our various credit facilities approximates fair value as the interest rate is variable. The term loan approximates fair value as the Company recently entered into that agreement.

Note 2—Summary of Significant Accounting Policies (Continued)

(e)   Cash and Cash Equivalents

        Cash and cash equivalents include cash on hand and investments in money market funds and investment grade securities held with high quality financial institutions. The Company considers all highly liquid instruments purchased with a remaining maturity of three months or less at the time of purchase to be cash equivalents.

(f)    Restricted Cash

        Restricted cash represents cash collateral required to be maintained in foreign bank accounts to serve as collateral for letters of credit, bonds or guarantees on several projects. The cash will remain restricted until the respective project has been completed, which typically is greater than one year.

(g)   Concentrations of Credit Risk

        Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash investments and accounts receivable.

        The Company maintains its cash accounts with high quality financial institutions. Although the Company currently believes that the financial institutions, with which it does business, will be able to fulfill their commitments to it, there is no assurance that those institutions will be able to continue to do so.

        The Company provides professional services, under contractual arrangements, to domestic and foreign governmental units, institutions and the private sector. To reduce credit risk, the Company performs ongoing credit evaluations of its clients and does not require collateral beyond customary retainers.

        At December 31, 2013, the accounts receivable related to the work performed prior to March 2011 under contracts in Libya, amounted to approximately $57,000,000. The Company believes that the amounts due will be collected, however, if future events preclude us from doing so, there could be a significant adverse impact on the Company's consolidated results of operations and consolidated financial position.

        The following tables show the number of the Company's clients which contributed 10% or more of revenue and accounts receivable, respectively:

        The following provides information with respect to total revenue from contracts with U.S. federal government agencies:

(h)   Allowance for Doubtful Accounts

        The allowance for doubtful accounts is an estimate prepared by management based on identification of the collectibility of specific accounts and the overall condition of the receivable portfolios. When evaluating the adequacy of the allowance for doubtful accounts, the Company specifically analyzes trade receivables, including retainage receivable, historical bad debts, client credits, client concentrations, client credit worthiness, current economic trends and changes in client payment terms. If the financial condition of clients were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required. Likewise, should the Company determine that it would be able to realize more of its receivables in the future than previously estimated, an adjustment to the allowance would increase earnings in the period such determination was made. The allowance for doubtful accounts is reviewed on a quarterly basis and adjustments are recorded as deemed necessary.

(i)    Property and Equipment

        Property and equipment is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization is provided over the estimated useful lives of the assets as follows:

        The Company capitalizes costs associated with internally developed and/or purchased software systems that have reached the application development stage and meet recoverability tests. Capitalized costs include external direct costs of materials and services utilized in developing or obtaining internal-use software, payroll and payroll-related expenses for employees who are directly associated with and devote time to the internal-use software project. Capitalization of such costs begins when the preliminary project stage is complete and ceases no later than the point at which the project is substantially complete and ready for its intended purpose. Costs for general and administrative, overhead, maintenance and training, as well as the cost of software that does not add functionality to existing systems, are expensed as incurred.

        Upon retirement or other disposition of these assets, the cost and related depreciation are removed from the accounts and the resulting gain or loss, if any, is reflected in results of operations. Expenditures for maintenance, repairs and renewals of minor items are charged to expense as incurred. Major renewals and improvements are capitalized.

(j)    Retainage Receivable

        Retainage receivable represents balances billed but not paid by clients pursuant to retainage provisions in the construction management contracts and will be due upon completion of specific tasks or the completion of the contract. The current portion of retainage receivable is included in accounts receivable and the long-term portion of retainage receivable is included in retainage receivable in the consolidated balance sheets.

(k)   Long-Lived Assets

        Acquired intangible assets consist of contract rights, client related intangibles and trade names arising from the Company's acquisitions. Contract rights represent the fair value of contracts in progress and backlog of an acquired entity. For intangible assets purchased in a business combination, the estimated fair values of the assets are used to establish the cost bases. Valuation techniques consistent with the market approach, the income approach and the cost approach are used to measure fair value. These assets are amortized over their estimated lives which range from three to fifteen years.

        The Company reviews long-lived assets to be held-and-used for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. If the sum of the undiscounted expected future cash flows over the remaining useful life of a long-lived asset is less than its carrying amount, the asset is considered to be impaired. Impairment losses are measured as the amount by which the carrying amount of the asset exceeds the fair value of the asset. When fair values are not available, the Company estimates fair value using the expected future cash flow discounted at a rate commensurate with the risks associated with the recovery of the asset. Assets to be disposed of are reported at the lower of carrying amount or fair value less costs to sell.

(l)    Goodwill

        Goodwill represents the excess of purchase price and other related costs over the value assigned to the net tangible and identifiable intangible assets of businesses acquired. Acquired intangible assets other than goodwill are amortized over their useful lives. For intangible assets purchased in a business combination, the estimated fair values of the assets are used to establish the cost bases. Valuation techniques consistent with the market approach, the income approach and the cost approach are used to measure fair value.

        Goodwill is tested annually for impairment in its fiscal third quarter. The Company has determined that it has two reporting units, the Project Management unit and the Construction Claims unit. The Company made that determination based on the similarity of the services provided, the methodologies in delivering our services and the similarity of the client base in each of these units. Goodwill is assessed for impairment using a two-step approach. In the first step of the impairment test, the Company compares the fair value of the reporting unit in which the goodwill resides to its carrying value. To the extent the carrying amount of a reporting unit exceeds its fair value, an indication exists that the reporting unit's goodwill may be impaired and the Company must perform a second more detailed assessment. The second step, if necessary, involves allocating the reporting unit's fair value to all of its recognized and unrecognized assets and liabilities in order to determine the implied fair value of the reporting unit's goodwill as of the assessment date. The implied fair value of the reporting unit's goodwill is then compared to the carrying amount of goodwill to quantify an impairment charge as of the assessment date.

        Application of the goodwill impairment test requires significant judgments including estimation of future cash flows, which is dependent on internal forecasts, estimation of the long-term rate of growth for the businesses, the useful life over which cash flows will occur, and determination of the Company's weighted average cost of capital. The Company's changes in estimates and assumptions could materially affect the determination of fair value and/or conclusions on goodwill impairment for each reporting unit. The Company performed its annual impairment test effective July 1, 2013 and noted no impairment for either of its reporting units. In the future, the Company will continue to perform the annual test during its fiscal third quarter unless events or circumstances indicate an impairment may have occurred before that time.

(m)  Investments

Hill International (Spain), S.A.

        The Company's subsidiary, Hill International (Spain), S.A. ("Hill Spain"), has the following cost-basis investments:

•

Concessia, Cartera y Gestion de Infrastructuras, S.A. ("Concessia")—Hill Spain has made payments totaling $4,239,000 towards an initial 5.16% interest in this entity which invests in the equity of companies which finance, construct and operate various public and private infrastructure projects. The payments represented approximately 66% of Hill Spain's total required capital contribution. Hill Spain had accrued the remaining commitment of approximately $2,120,000 and had included that amount in the cost of the investment and in other liabilities in the accompanying consolidated balance sheet at December 31, 2012. During 2013, the aggregate capitalization of Concessia was reduced from approximately €93,000,000 to approximately €71,000,000. At that time, Hill Spain chose to reduce its total investment to a 4.45% interest and to distribute the excess 0.71% interest to the other shareholders of Concessia. Hill Spain has reduced both the cost of the investment and other liabilities by $2,120,000.



•

Nuevo Hospital de Burgos, S.A.—Hill Spain paid $3,761,000 for a 5.18% interest in this entity which, on completion of construction, will operate a new hospital in Burgos, Spain. On January 12, 2012 Hill Spain signed an agreement to sell its entire holding to its affiliate Concessia which is subject to the approval of the local authority, the owner of the facility and the financial institutions involved in the project. Hill Spain received a down payment of $3,149,000 and has accrued a receivable for $612,000. Although the final price is subject to certain conditions, the Company expects the investment to be fully recovered.

Other

        The Company will, in the ordinary course, form joint ventures for specific projects. These joint ventures typically require limited or no investment and simply provide a pass-through for the Company's billings. Any distributions in excess of the Company's billings are accounted for as income when received.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Summary of Significant Accounting Policies (Continued)

(n)   Due to Bank

        Under the Company's cash-management system, certain cash accounts reflect credit balances to the extent checks were disbursed but not immediately funded at the bank. The Company manages this process daily and ensures all checks are funded when presented.

(o)   Deferred Revenue

        In certain instances the Company may collect advance payments from clients for future services. Upon receipt, the payments are reflected as deferred revenue in the Company's consolidated balance sheets. As the services are performed, the Company reduces the balance and recognizes revenue.

(p)   Deferred Rent

        Rent expenses for operating leases which include scheduled rent increases is determined by expensing the total amount of rent due over the life of the operating lease on a straight-line basis. The difference between the rent paid under the terms of the lease and the rent expensed on a straight-line basis is recorded as a liability. The deferred rent at December 31, 2013 and 2012 was $3,043,000 and $2,792,000, respectively, and is included in other liabilities in the consolidated balance sheet.

(q)   Income Taxes

        The Company estimates income taxes in each of the jurisdictions in which it operates. This process involves estimating its actual current tax exposure together with assessing temporary differences resulting from differing treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities, which are included within the Company's consolidated balance sheets. The Company assesses the likelihood that the deferred tax assets will be recovered from future taxable income and to the extent it believes recovery is not likely, the Company establishes a valuation allowance. To the extent the Company establishes a valuation allowance in a period, it must include an expense within the tax provision in the consolidated statements of earnings. The Company has recorded a valuation allowance to reduce the deferred tax asset to an amount that is more likely to be realized in future years. If the Company determines in the future that it is more likely that the deferred tax assets subject to the valuation allowance will be realized, then the previously provided valuation allowance will be adjusted.

        The Company recognizes a tax benefit in the financial statements for an uncertain tax position only if management's assessment is that the position is "more likely than not" (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term "tax position" refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for interim or annual periods.

(r)   Revenue Recognition

        The Company generates revenue primarily from providing professional services to its clients. Revenue is generally recognized upon the performance of services. In providing these services, the Company may incur reimbursable expenses, which consist principally of amounts paid to subcontractors and other third parties and travel and other job related expenses that are contractually reimbursable

56

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Summary of Significant Accounting Policies (Continued)

from clients. The Company has determined that it will include reimbursable expenses in computing and reporting its total revenue as long as the Company remains responsible to the client for the fulfillment of the contract and for the overall acceptability of all services provided.

        The Company earns its revenue from time-and-materials, cost-plus and fixed-price contracts. If estimated total costs on any contract indicate a loss, the Company charges the entire estimated loss to operations in the period the loss becomes known. The cumulative effect of revisions to revenue, estimated costs to complete contracts, including penalties, incentive awards, change orders, claims, anticipated losses, and others are recorded in the accounting period in which the events indicating a loss are known and the loss can be reasonably estimated. Such revisions could occur at any time and the effects may be material.

Time-and-Materials Contracts

        Under its time-and-materials contracts, the Company negotiates hourly billing rates and charges its clients based on the actual time that the Company spends on a project. In addition, clients reimburse the Company for its actual out-of-pocket costs of materials and other direct incidental expenditures that the Company incurs in connection with its performance under the contract. Its profit margins on time-and-materials contracts fluctuate based on actual labor and overhead costs that the Company directly charges or allocates to contracts compared with negotiated billing rates. Revenue on these contracts are recognized based on the actual number of hours the Company spends on the projects plus any actual out-of-pocket costs of materials and other direct incidental expenditures that the Company incurs on the projects. Its time-and-materials contracts generally include annual billing rate adjustment provisions.

Cost-Plus Contracts

        The Company has two major types of cost-plus contracts:

Cost-Plus Fixed Fee

        Under cost-plus fixed fee contracts, the Company charges its clients for its costs, including both direct and indirect costs, plus a fixed negotiated fee. In negotiating a cost-plus fixed fee contract, the Company estimates all recoverable direct and indirect costs and then adds a fixed profit component. The total estimated cost plus the negotiated fee represents the total contract value. The Company recognizes revenue based on the actual labor costs, based on hours of labor effort, plus non-labor costs the Company incurs, plus the portion of the fixed fee the Company has earned to date. The Company invoices for its services as revenue is recognized or in accordance with agreed-upon billing schedules. Aggregate revenue from cost-plus fixed fee contracts may vary based on the actual number of labor hours worked and other actual contract costs incurred. However, if actual labor hours and other contract costs exceed the original estimate agreed to by its client, the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in order to receive additional revenue relating to the additional costs (see "Change Orders and Claims").

Cost-Plus Fixed Rate

        Under its cost-plus fixed rate contracts, the Company charges clients for its costs plus negotiated rates based on its indirect costs. In negotiating a cost-plus fixed rate contract, the Company estimates

57

Table of Contents

HILL INTERNATIONAL, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Continued)

Note 2—Summary of Significant Accounting Policies (Continued)

all recoverable direct and indirect costs and then adds a profit component, which is a percentage of total recoverable costs to arrive at a total dollar estimate for the project. The Company recognizes revenue based on the actual total number of labor hours and other costs the Company expends at the cost plus the fixed rate the Company negotiated. Similar to cost-plus fixed fee contracts, aggregate revenue from cost-plus fixed rate contracts may vary and the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in order to receive additional revenue relating to any additional costs that exceed the original contract estimate (see "Change Orders and Claims").

        Labor costs and subcontractor services are the principal components of its direct costs on cost-plus contracts, although some include materials and other direct costs. Some of these contracts include a provision that the total actual costs plus the fee will not exceed a guaranteed price negotiated with the client. Others include rate ceilings that limit the reimbursement for general and administrative costs, overhead costs and materials handling costs. The accounting for these contracts appropriately reflects such guaranteed price or rate ceilings.

Firm Fixed-Price ("FFP") Contracts

        The Company's FFP contracts have historically accounted for most of its fixed-price contracts. Under FFP contracts, the Company's clients pay an agreed amount negotiated in advance for a specified scope of work. The Company recognizes revenue on FFP contracts using the percentage-of-completion method (recognizing revenue as costs are incurred). Profit margins the Company recognizes in all periods prior to completion of the project on any FFP contract depend on the accuracy of the Company's estimates of approximate revenue and expenses and will increase to the extent that its current estimates of aggregate actual costs are below amounts previously estimated. Conversely, if the Company's current estimated costs exceed prior estimates, its profit margins will decrease and the Company may realize a loss on a project. In order to increase aggregate revenue on the contract, the Company generally must obtain a change order, contract modification, or successfully prevail in a claim in order to receive payment for the additional costs (see "Change Orders and Claims").

Change Orders and Claims

        Change orders are modifications of an original contract that effectively change the provisions of the contract without adding new provisions. Either the Company or its client may initiate change orders. They may include changes in specifications or design, manner of performance, facilities, equipment, materials, sites and period of completion of the work. Claims are amounts in excess of the agreed contract price that the Company seeks to collect from its clients or others for client-caused delays, errors in specifications and designs, contract terminations, change orders that are either in dispute or are unapproved as to both scope and price, or other causes of unanticipated additional contract costs.

        Change orders and claims occur when changes are experienced once contract performance is underway. Change orders are sometimes documented and terms of such change orders are agreed with the client before the work is performed. Sometimes circumstances require that work progresses before agreement is reached with the client. Costs related to change orders and claims are recognized when they are incurred. Change orders and claims are included in total estimated contract revenue when it is

Note 2—Summary of Significant Accounting Policies (Continued)

probable that the change order or claim will result in a bona fide addition to contract value that can be reliably estimated. No profit is recognized on claims until final settlement occurs; unapproved change orders are evaluated as claims. This can lead to a situation where costs are recognized in one period and revenue is recognized when client agreement is obtained or claims resolution occurs, which can be in subsequent periods.

        The Company has contracts with the U.S. government that contain provisions requiring compliance with the U.S. Federal Acquisition Regulations ("FAR"). These regulations are generally applicable to all of its federal government contracts and are partially or fully incorporated in many local and state agency contracts. They limit the recovery of certain specified indirect costs on contracts subject to the FAR. Cost-plus contracts covered by the FAR provide for upward or downward adjustments if actual recoverable costs differ from the estimate billed under forward pricing arrangements. Most of its federal government contracts are subject to termination at the convenience of the client. Contracts typically provide for reimbursement of costs incurred and payment of fees earned through the date of such termination.

        Federal government contracts which are subject to the FAR and some state and local governmental agencies require audits, which are performed for the most part by the Defense Contract Audit Agency ("DCAA"). The DCAA audits the Company's overhead rates, cost proposals, incurred government contract costs, and internal control systems. During the course of its audits, the DCAA may question incurred costs if it believes the Company has accounted for such costs in a manner inconsistent with the requirements of the FAR or Cost Accounting Standards and recommend that its U.S. government corporate administrative contracting officer disallow such costs. Historically, the Company has not experienced significant disallowed costs as a result of such audits. However, the Company can provide no assurance that the DCAA audits will not result in material disallowances of incurred costs in the future.

(s)   Share-Based Compensation

        The Company uses the Black-Scholes option pricing model to measure the estimated fair value of options to purchase the Company's common stock. The compensation expense, less estimated forfeitures, is being recognized over the service period on a straight-line basis. The Company's policy is to use newly issued shares to satisfy the exercise of stock options.

(t)    Advertising Costs

        Advertising costs are expensed as incurred and amounted to the following (in thousands):

(u)   Earnings per Share

        Basic earnings per common share has been computed using the weighted-average number of shares of common stock outstanding during the year. Diluted earnings per common share incorporates the incremental shares issuable upon the assumed exercise of stock options using the treasury stock method.

        Dilutive stock options increased average common shares outstanding by approximately 225,000 shares for the year ended December 31, 2013. For the years ended December 31, 2012 and 2011, stock options were anti-dilutive.

        Options to purchase 5,364,000 shares, 4,492,000 shares and 2,385,000 shares of the Company's common stock were not included in the calculation of common shares outstanding for the years ended December 31, 2013, 2012 and 2011, respectively, because they were anti-dilutive.

(v)   Recent Accounting Pronouncements

        In February 2013, the FASB issued ASU No. 2013-2, which amends the Comprehensive Income Topic of the ASC. The ASU requires companies to report either on the income statement or disclose in the footnotes to the financial statement the effects on earnings from items that are reclassified out of the category of shareholder equity called accumulated other comprehensive income. The adjustments will consist of amounts from the fiscal period covered by the financial statements. Companies will also have to make cross references to other disclosures required in U.S. GAAP for other line items used to adjust earnings. The FASB wants this requirement applied to amounts that are initially transferred to another balance sheet item before being entered as an adjustment to earnings. The Company adopted the ASU on January 1, 2013. The ASU did not affect the Company's consolidated results of operations, financial condition or liquidity.

Note 3—Acquisitions

        Our recent acquisition activity is detailed below. The Company's consolidated financial statements include the operating results of these businesses from their respective dates of acquisition. Pro forma results of operations for these acquisitions have not been presented because they are not material to the Company's consolidated results of operations, either individually or in the aggregate.

        The Company expenses all acquisition-related costs plus any anticipated restructuring costs for which it is not obligated at the acquisition date, rather than including such costs as a component of the purchase consideration. During 2013, 2012 and 2011, the Company expensed $455,000, $84,000 and $164,000, respectively, of acquisition-related costs.

Collaborative Partners, Inc.

        On December 23, 2013, Hill acquired all of the outstanding common stock of Collaborative Partners, Inc. ("CPI"), a firm that provides project management, strategic planning and regulatory services for healthcare, life sciences, educational, commercial and residential construction projects throughout New England. CPI, which has 20 professionals, has offices in Boston, Massachusetts and Providence, Rhode Island. The acquisition expands the Company's project management business in the New England region of the United States. At closing, the sellers received $2,450,000 in the form of 678,670 shares of the Company's common stock priced at $3.61 per share. On March 7, 2014, the

60

Note 3—Acquisitions (Continued)

sellers received 171,308 shares of common stock with a value of $618,000 representing CPI's common equity in excess of $600,000. On December 23, 2014, the sellers will receive, subject to potential offset, an additional $350,000 in shares of common stock; the number of shares will be determined based on the average closing price of the common stock for the ten trading days ending on December 18, 2014. The Agreement also provides that (1) should the price of the Company's common stock not increase by 50% to $5.42 on December 23, 2014, the Company will issue additional shares to the sellers representing the difference between $5.42 and the price on December 23, 2014, and (2) the sellers are entitled to receive additional shares of the Company's common stock for (i) 50% of the operating profit of CPI in excess of $1,000,000 for the first 12-month period after closing, but in no event more than $500,000, and (ii) 5% of the net revenue backlog in excess of $10,000,000 on the date 60 days after closing. The Company has estimated and accrued $2,697,000 for the potential additional consideration which is included in other current liabilities in the consolidated balance sheet at December 31, 2013. The portion of the liability attributable to the change in the common stock price will be remeasured at each reporting date and any change in the liability will be reflected in the consolidated statement of operations. The Company acquired intangible assets and goodwill amounting to $1,516,000 and $3,049,000, respectively. The acquired intangible assets have a weighted average life of 5.3 years. The acquired intangible assets consist of a client relationship intangible of $509,000 with a ten-year life and a contract intangible of $1,007,000 with a three-year life. Goodwill, which is not deductible for income tax purposes, has been allocated to the Project Management operating segment.

Binnington Copeland & Associates (Pty.) Ltd.

        On May 30, 2013, Hill International N.V., the Company's wholly-owned subsidiary, acquired all of the outstanding common stock of Binnington Copeland & Associates (Pty.) Ltd. and BCA Training (Pty.) Ltd. (together "BCA"). BCA, with 34 professionals, has offices in Johannesburg and Cape Town, South Africa. The acquisition provides the Company's claims business access to Africa's large infrastructure and mining projects and allows for expansion into the rest of sub-Saharan Africa. Consideration consisted of $2,000,000 plus a potential earn-out, both payable in shares of the Company's common stock. The purchase price is payable as follows: $1,072,400 (the "Closing Date Payment") on the closing date, $927,600 (the "Second Tranche Payment") on July 31, 2013 and an earn-out (the "Third Tranche Payment") to be determined in the third quarter of 2014. The Company issued 379,655 shares of its common stock in satisfaction of the Closing Date Payment; the number of shares was determined by dividing the Closing Date Payment by the average closing price of our common stock for the thirty trading days ending on May 17, 2013. On July 31, 2013, the Company issued 331,444 shares of its common stock in satisfaction of the Second Tranche Payment. The number of shares was determined by dividing the Second Tranche Payment by the average closing price of our common stock for the thirty trading days ending on July 19, 2013. The shares issuable in satisfaction of the Third Tranche Payment will be determined by dividing the Third Tranche Payment by the average closing price of our common stock for the thirty trading days ending on July 21, 2014. The actual amount of the Third Tranche Payment will be determined by comparing the average net profit before taxes for the two-year periods ending July 31, 2014 to the net profit before taxes for the year ended July 31, 2012, and multiplying the excess, if any, by 2.205. The Third Tranche Payment is estimated to be approximately $902,000. The Company reflected the liability for the Third Tranche Payment in other current liabilities in the consolidated balance sheet at December 31, 2013. The Company acquired intangible assets and goodwill amounting to 13,143,000 South African Rand (ZAR) (approximately $1,312,000 on the acquisition date) and ZAR 12,873,000 ($1,285,000), respectively. The acquired

intangible assets have a weighted average life of 8.2 years. The acquired intangible assets consist of a client relationship intangible of ZAR 10,546,000 ($1,053,000) with a ten-year life, a contract intangible of ZAR 1,863,000 ($186,000) with an 8-month life and a trade name intangible of ZAR 734,000 ($73,000) with a two-year life. Goodwill, which is not deductible for income tax purposes, has been allocated to the Construction Claims operating segment.

Engineering S.A.

        On February 28, 2011, the Company's subsidiary, Hill Spain, indirectly acquired 60% of the outstanding common stock of Engineering S.A., one of the largest project management firms in Brazil with approximately 400 professionals. It has main offices in Rio de Janeiro and Sao Paulo and an additional office in Parauapebas. Engineering S.A. provides project management, construction management and engineering consulting services throughout Brazil. Total consideration will not exceed 42,000,000 Brazilian Reais ("BR") (approximately $25,336,000 at the date of acquisition) consisting of an initial cash payment of BR22,200,000 (approximately $13,392,000) plus minimum additional payments of BR7,400,000 (approximately $4,464,000) due on each of April 30, 2012 and 2013 and a potential additional payment of BR5,000,000 ($3,016,000). The Company acquired intangible assets and goodwill amounting to BR24,540,000 ($14,783,000) and BR46,339,000 ($27,987,000), respectively. The acquired intangible assets have a weighted average life of 7.7 years. The acquired intangible assets consist of a client relationship intangible of BR13,942,000 ($8,399,000) with a ten-year life, a contract intangible of BR8,385,000 ($5,051,000) with a two-year life and a trade name intangible of BR2,213,000 ($1,333,000) with a fifteen-year life. Goodwill, which is deductible for income tax purposes, has been allocated to the Project Management operating segment. Also, ESA's shareholders entered into an agreement whereby the minority shareholders have a right to compel ("ESA Put Option") Hill Spain to purchase any or all of their shares during the period from February 28, 2014 to February 28, 2021. Hill Spain also has the right to compel ("ESA Call Option") the minority shareholders to sell any or all of their shares during the same time period. The purchase price for such shares shall be seven times the earnings before interest and taxes for ESA's most recently ended fiscal year, net of any financial debt plus excess cash multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of purchase, but in the event the ESA Call Option is exercised by Hill Spain, the purchase price shall be increased by five percent. The ESA Put Option and the ESA Call Option must be made within three months after the audited financial statements of ESA have been completed.

        The Company estimated the fair value of the potential additional payments to total approximately BR17,200,000 (approximately $10,376,000) and has discounted these amounts using an interest rate of 4.72%, the weighted average interest rate on the outstanding borrowings under the Company's Credit Agreement at the acquisition date. The Company paid the first installment amounting to 6,624,000 BRL (approximately $3,508,000 on April 30, 2012 and paid the second installment amounting to 11,372,000 BRL (approximately $5,095,000) on July 23, 2013.

Gerens Management Group, S.A.

        On February 15, 2008, the Company's subsidiary, Hill International N.V. (formerly Hill International S.A.), acquired 60% of the outstanding capital stock of Gerens Management Group, S.A., whose name was subsequently changed to Hill International (Spain), S.A. ("Hill Spain"). In connection with the acquisition, Hill Spain's shareholders entered into an agreement whereby the minority

Note 3—Acquisitions (Continued)

shareholders have a right to compel ("Gerens Put Option") Hill International N.V. to purchase any or all of their shares during the period from March 31, 2010 to March 31, 2020. Hill International N.V. also has the right to compel the minority shareholders to sell any or all of their shares during the period from March 31, 2011 to March 31, 2021. The purchase price for such shares shall be the greater of (a) €18,000,000 ($23,808,000 as of December 31, 2012) increased by the General Price Index (capped at 3.5% per annum) or (b) ten times Hill Spain's earnings before interest and income taxes for the prior fiscal year, multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of purchase. Such amount may be adjusted for increases in equity subsequent to the acquisition date, and can be paid in cash or shares of our common stock at the option of the sellers.

        During late 2011 through late 2012, ten minority shareholders, who owned approximately 23.9% of the outstanding common stock of Hill Spain, exercised their Gerens Put Options. The Company accrued the liability of approximately €7,166,000 (approximately $9,477,000) which is included in other current liabilities in the consolidated balance sheet at December 31, 2012. The balance includes interest of approximately €115,000 (approximately $152,000) which has been charged to interest expense in the consolidated statement of operations for the year ended December 31, 2012. The aggregate consideration plus interest was paid on January 3, 2013. In connection with the transactions, the Company reduced noncontrolling interests by €2,717,000 (approximately $3,594,000), increased goodwill by €1,300,000 (approximately $1,720,000) and increased intangible assets by €4,334,000 (approximately $5,580,000) during 2012.

        During 2013, the remaining minority shareholders, who owned approximately 6.8% of the outstanding common stock of Hill Spain, exercised their Gerens Put Options. The Company now owns 100% of Hill Spain. The aggregate consideration plus interest was paid on December 4, 2013 in the amount of €2,031,000 (approximately $2,793,000). The balance includes interest of approximately €42,000 (approximately $56,000). In connection with the transactions, the Company reduced noncontrolling interests by €828,000 (approximately $1,094,000), increased goodwill by €348,000 (approximately $460,000) and increased intangible assets by approximately €1,161,000 (approximately $1,534,000).

Note 4—Accounts Receivable (Continued)

        Unbilled receivables primarily represent revenue earned on contracts, which the Company is contractually precluded from billing until predetermined future dates.

        Included in billed receivables are $2,030,000 and $2,066,000 of the amounts due from various branches of the U.S. federal government and $99,643,000 and $84,773,000 of receivables from foreign governments at December 31, 2013 and December 31, 2012, respectively.

        Bad debt expense of $3,928,000, $3,209,000 and $3,178,000 is included in selling, general and administrative expenses in the consolidated statements of operations for the years ended December 31, 2013, 2012 and 2011, respectively.

        Through December 31, 2013, accounts receivable related to work performed by Hill prior to March 2011 pursuant to contracts with the Libyan government were reduced by approximately $3,100,000. The reduction consisted of a cash payment by the Libyan Organization for the Development of Administrative Centres ("ODAC") of approximately 3,000,000 Libyan dinars ("LYD") ($2,400,000) that was made directly to Hill and a cash payment of approximately LYD 800,000 ($700,000) that was made by ODAC to Libyan tax authorities on Hill's behalf. The LYD 3,000,000 cash payment made directly to Hill is not freely convertible into other currencies. As a result, this cash remains in Hill's Libyan bank account. At December 31, 2013, the remaining accounts receivable outstanding related to Hill's work in Libya amounted to approximately $57,000,000.

        During February 2014, the Company received additional payments of approximately $6,100,000 consisting of approximately 200,000 pounds sterling ($300,000), approximately LYD 2,100,000 ($1,700,000) and $4,100,000 in U.S. dollars.

        Since the end of the Libyan civil unrest in October 2011, the Company has sought to recover its receivable from ODAC through ongoing negotiations rather than pursue its legal rights for payment under the contracts. The Company believes that this course of action provides the best likelihood for recovery as it could result in completion of and payment on the existing contracts as well as the potential for the award of new contracts. There is at present no agreement, understanding or timetable for further payments of Hill's accounts receivable from ODAC or a return to work on Hill's existing contracts. However, management believes that these payments, along with letters of credit of approximately $14,000,000 posted in our favor by ODAC, were made in good faith and are a positive indication that ODAC intends to satisfy its obligations to Hill. However, the Company cannot predict with certainty when, or if, the remaining accounts receivable will be paid by the Libyan authorities or when work will resume there. In the event that the Company does not realize any further payments, there could be a significant adverse impact on its consolidated results of operations and consolidated financial position.

        Among other things, the Term Loan Agreement:

•

Limits the indebtedness which the Company and its subsidiaries may incur (including certain intercompany indebtedness, such as indebtedness from foreign subsidiaries to the Company);



•

Limits the investments, acquisitions and dividends which the Company and its subsidiaries may make (including investments by the Company in its foreign subsidiaries);



•

Limits the amount of cash the Company and its subsidiaries may accumulate;



•

Requires the Company to take certain actions, including providing monthly reporting to the Term Loan Lenders; and



•

Contains representations, warranties, affirmative and negative covenants and events of default which are substantially similar to those contained in the Credit Agreement (except in respect of financial covenants which are less restrictive than those under the Credit Agreement) and the other Loan Documents (as defined in the Credit Agreement).

        At December 31, 2013, the Company was in compliance with all of the Term Loan covenants.

        In connection with the Term Loan Agreement, the Company agreed, under certain conditions, to allow certain Term Loan Lenders to appoint two non-voting observers to the Company's board of directors.

        The Company will pay interest on amounts outstanding from time to time under the Term Loan at a rate per annum equal to 7.50%; provided, however, such rate may be increased to 9.50% per annum if fixed price contracts (as defined under the Term Loan Agreement) or certain accounts receivable of the Company and its subsidiaries exceed percentages specified in the Term Loan Agreement.

        Also, contemporaneous with its entry into the Term Loan Agreement, the Company entered into a Fee Letter. The Fee Letter requires the Company to pay to the Lenders an exit fee (the "Exit Fee"), which fee shall be earned in full on the Closing Date and due and payable on the date the Term Loan is paid in full (the "Exit Date"). "Exit Fee" means the amount, if any, when paid to the Term Loan Lenders on the Exit Date, that will result in the internal annual rate of return (the "IRR") to the Term Loan Lenders (the "IRR") on the Exit Date being equal to, but no greater than, 20%; provided, that in no event shall the Exit Fee Amount be less than $0 or greater than $11,790,000. The IRR is to be calculated as the rate of return earned by the Term Loan Lenders on their initial investment in the Term Loan (to be calculated as the principal amount of the Term Loan less the Closing Fee of $25,000,000) through the Exit Date taking into account the payment by the Company to the Term Loan Lenders of all principal, interest and other payments to the Term Loan Lenders pursuant to the Term Loan Agreement.

        Additionally, the Company is required to make the following mandatory prepayments/payments and/or commitment reductions in respect of the Company's indebtedness under the Credit Agreement and under the Term Loan Agreement:

the remaining net proceeds or Excess Cash Flow, as applicable, to prepay the outstanding principal amount of the Term Loan.

        None of the payments received in 2013 from ODAC in connection with the "Net Libya Receivable" referred to above are payable under the Credit Agreement or the Term Loan because the amount was paid in Libyan dinars which is not a readily convertible currency. In addition, there were no sales of assets nor excess cash-flow (as defined in the "Third Amendment") generated in 2013.

        In connection with the Term Loan Agreement, the Company incurred approximately $609,000 of costs which were charged to interest expense and related financing costs, net in 2012. In addition, the Company incurred costs of approximately $2,975,000 in connection with establishing the Term Loan. Such costs have been deferred and will be amortized to interest expense over the life of the Term Loan.

At December 31, 2013 and 2012, there were no borrowings outstanding on any of these facilities which are renewed automatically every three months.

        A revolving credit facility with Barclays Bank PLC for up to £550,000 (approximately $907,000) at December 31, 2013, with interest of 2.00% plus the Bank of England rate of 0.50% (or 2.50%) at December 31, 2013, collateralized by cross guarantees of several of the United Kingdom companies. Aggregate of all debt owing to the bank will be, at all times, covered 3 times by the aggregate value of the UK accounts receivable less than 90 days old and excluding any receivables which are due from any associate, subsidiary or overseas client. At December 31, 2013 and 2012, there were no borrowings outstanding. This facility is on demand with no fixed expiration date. It is subject to an annual review on September 12, 2014.

        At December 31, 2013, the Company had $6,759,000 of available borrowing capacity under its foreign credit agreements.

        In connection with the acquisition of Engineering S.A., the Company incurred indebtedness to the sellers amounting to 17,200,000 Brazilian Reais (approximately $10,376,000 at the date of acquisition) and discounted that amount using an interest rate of 4.72%, the Company's weighted average interest rate at that time. The Company paid the first installment amounting to BR 6,624,000 (approximately $3,508,000) on April 30, 2012 and paid the second installment amounting to 11,372,000 BRL (approximately $5,095,000) on July 23, 2013.

The shares vested annually over a five-year period commencing on February 28, 2008. Through December 31, 2013, the Company has issued 319,000 shares of its common stock. Under the terms of the plan, no further grants may be made. Information with respect to the plan follows (in thousands):

2006 Employee Stock Option Plan

        The 2006 Employee Stock Option Plan, as amended, covers 8,000,000 shares of the Company's common stock. Under its terms, directors, officers and employees of the Company and its subsidiaries are eligible to receive non-qualified and incentive stock options. Options granted to non-employee directors vest immediately and have a five year contractual term. Options granted to officers and employees vest over five years and have a seven-year contractual term. Generally, each option has an exercise price equal to the closing quoted market price of a share of the Company's common stock on the date of grant. For grants of incentive stock options, if the grantee owns, or is deemed to own, 10% or more of the total voting power of the Company, then the exercise price shall be 110% of the closing quoted market price on the date of grant and the option will have a five-year contractual term. Options that are forfeited or expire are available for future grants. At December 31, 2013, a total of 1,366,844 shares of common stock were reserved for future issuance under the plan.

        The Black-Scholes option valuation model is used to estimate the fair value of the options. The following table summarizes the fair value of options granted during 2013, 2012 and 2011 and the assumptions used to estimate the fair value:

        The expected term of the options is estimated based on the "simplified method" as permitted by SAB No. 110. Expected volatility was calculated using the average historical volatility of similar public companies through June 30, 2011 and of the Company thereafter. The risk-free interest rate is based

Note 13—Income Taxes

        The effective tax rates for the years ended December 31, 2013, 2012 and 2011 were 63.0%, (104.2%) and 55.6%, respectively. The difference in the Company's 2013 effective tax rate over 2012 was primarily the result of not recording an income tax benefit related to the 2013 U.S. net operating loss which management believes the Company will not be able to utilize. In addition, the Company recognized higher income tax expense related to withholding taxes on foreign operations. These items were partially offset by the $2,473,000 reversal for uncertain tax positions based on management's assessment that those items were effectively settled with a foreign jurisdiction.

        The components of earnings (loss) before income taxes by United States and foreign jurisdictions were as follows:

        Income tax (benefit) expense consists of the following:

        The tax effect of temporary differences that give rise to deferred tax assets and deferred tax liabilities are as follows:

        In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities and projected future taxable income in making this assessment. Management evaluates the need for valuation allowances on the deferred tax assets according to the

82

HILL INTERNATIONAL, INC. AND SUBSIDIARIES

Note 13—Income Taxes (Continued)

provisions of ASC 740, Income Taxes. They consider both positive and negative evidence. In making this determination, management assesses all of the evidence available at the time including recent earnings, internally-prepared income projections, and historical financial performance.

        At December 31, 2012, due to recurring net operating losses in the United States, management determined that it was more likely than not that the Company would not be able to utilize its U.S.-related deferred tax assets. As a consequence, the Company recorded a valuation allowance of $17,707,000 at that time. In 2013, the Company recorded an additional U.S. deferred tax asset of $9,062,000 primarily related to a U.S.-based net operating loss of $24,902,000. Consequently, the Company recorded an additional valuation allowance at December 31, 2013 of $9,062,000. As a result, the U.S. deferred tax assets, net of U.S. based deferred tax liabilities, at December 31, 2013 are fully reserved. The total valuation allowance related to the U.S. deferred tax assets at December 31, 2013 is $26,769,000. Cumulative U.S. federal and state net operating losses at December 31, 2013 are $63,365,000 and $66,472,000, respectively.

        At December 31, 2013 and 2012, there were approximately $24,013,000 and $20,337,000, respectively, of gross foreign net operating loss carry forwards. The majority of these net operating loss carry forwards have an unlimited carry forward period. A valuation allowance of $4,489,000 and $4,714,000 was recorded at December 31, 2013 and 2012, respectively, related to the foreign net operating losses in certain jurisdictions. It is anticipated that these losses will not be utilized due to continuing losses in these jurisdictions.

        The Company has made no provision for U.S. taxes on $119,416,000 of cumulative earnings of foreign subsidiaries as those earnings are intended to be reinvested for an indefinite period of time. Upon distribution of these earnings in the form of dividends or otherwise, the Company may be subject to U.S. income taxes and foreign withholding taxes. It is not practical, however, to estimate the amount of taxes that may be payable on the eventual repatriation of these earnings.

        In 2013, deferred tax assets and additional paid in capital were reduced by $583,000 and in 2012, deferred tax assets and additional paid in capital were increased by $161,000 to record the differential between book expense and tax expense related to the vesting of restricted stock.

        The Company will recognize a tax benefit in the financial statements for an uncertain tax position only if management's assessment is that the position is "more likely than not" (i.e., a likelihood greater than 50 percent) to be allowed by the tax jurisdiction based solely on the technical merits of the position. The term "tax position" refers to a position in a previously filed tax return or a position expected to be taken in a future tax return that is reflected in measuring current or deferred income tax assets and liabilities for financial reporting purposes.

        The following table indicates the changes to the Company's uncertain tax positions for the years ended December 31, 2013 and 2012 including interest and penalties:

        The Company files income tax returns in the U.S. federal jurisdiction and in various state and foreign jurisdictions. The Company generally is no longer subject to U.S. federal, state or foreign examinations by tax authorities for tax years prior to 2010.

        The Company's policy is to record income tax related interest and penalties in income tax expense. At December 31, 2013 and 2012, the Company has accrued $172,000 and $100,000, respectively, related to potential interest and penalties.

        The Company's income tax returns are based on calculations and assumptions that are subject to examinations by the Internal Revenue Service and other tax authorities. While the Company believes it has appropriate support for the positions taken on its tax returns, the Company regularly assesses the potential outcomes of these examinations and any future examinations for the current or prior years in determining the adequacy of its provision for income taxes. As part of its assessment of potential adjustments to its tax returns, the Company increases its current tax liability to the extent an adjustment would result in a cash tax payment or decreases its deferred tax assets to the extent an adjustment would not result in a cash tax payment. The Company continually assesses the likelihood and amount of potential adjustments and adjusts the income tax provision, the current tax liability and deferred taxes in the period in which the facts that give rise to a revision become known.

Note 14—Commitments and Contingencies

General Litigation

        M.A. Angeliades, Inc. ("Plaintiff") has filed a complaint with the Supreme Court of New York against the Company and the New York City Department of Design and Construction ("DDC") regarding payment of approximately $8,771,000 for work performed as a subcontractor to the Company plus interest and other costs. The Company has accrued approximately $2,340,000, including interest of $448,000, based on invoices received from Plaintiff who has refused to provide invoices for the additional work that Plaintiff claims to have performed. Until such time as the Company obtains invoices for the additional work and is able to provide those invoices to DDC for reimbursement or there is a full resolution of the litigation, it has no intention of paying Plaintiff. The Company believes that its position is defensible, however, there can be no assurance that it will receive a favorable verdict should this case proceed to trial.

Note 14—Commitments and Contingencies (Continued)

        From time to time, the Company is a defendant or plaintiff in various legal actions which arise in the normal course of business. As such the Company is required to assess the likelihood of any adverse outcomes to these matters as well as potential ranges of probable losses. A determination of the amount of the provision required for these commitments and contingencies, if any, which would be charged to earnings, is made after careful analysis of each matter. The provision may change in the future due to new developments or changes in circumstances. Changes in the provision could increase or decrease the Company's earnings in the period the changes are made. It is the opinion of management, after consultation with legal counsel, that the ultimate resolution of these matters will not have a material adverse effect on the Company's financial condition, results of operations or cash flows.

Off-Balance Sheet Arrangements

        The Company enters into agreements with banks for the banks to issue bonds to clients or potential clients for three separate purposes as follows:

(1)

Certain of the Company's subsidiaries (Hill International S.A., Hill International (UK) Ltd. and Hill International (Middle East) Ltd.) have entered into contracts for the performance of construction management services which provide that the Company receive advance payment of some of the management fee from the client prior to commencement of the construction project. However, the clients require a guarantee of service performance in the form of an advance payment bond. These bonds are evidenced by Letters of Guarantee issued by the subsidiaries' banks in favor of the clients. In some cases these clients also require a parent company guarantee.



(2)

The Company may also enter into certain contracts which require a performance bond to be issued by a bank in favor of the client for a portion of the value of the contract. These bonds may be exercised by the client in instances where the Company fails to provide the contracted services.



(3)

Certain clients may require bonds as part of the bidding process for new work. The bid bonds are provided to demonstrate the financial strength of the companies seeking the work and are usually outstanding for short periods. If the bid is rejected the bond is cancelled and if the bid is accepted the Company may be required to provide a performance bond.

        The maximum potential future payment under these arrangements at December 31, 2013 was $71,433,000.

        Cash held in restricted accounts as collateral for the issuance of performance and advance payment bonds and letters of credit at December 31, 2013 and 2012 were $18,506,000 and $21,226,000, respectively.

Acquisition-related

        On February 28, 2011, the Company's wholly-owned subsidiary Hill Spain acquired an indirect 60% interest in Engineering S.A. ("ESA"), a firm located in Brazil, for cash amounting to 22,200,000 Brazilian Reais ("BR") (approximately $11,757,000). Minimum additional payments were made on April 30, 2012 in the amount of BR 6,624,000 (approximately $3,508,000 on that date) and on July 23, 2013 in the amount of BR 11,372,000 (approximately $5,095,000). Under certain circumstances, the Company may be required to pay BR 5,000,000 (approximately $2,468,000 at December 31, 2012) in

addition to the minimum payments. Also, ESA's shareholders entered into an agreement whereby the minority shareholders have a right to compel ("ESA Put Option") Hill Spain to purchase any or all of their shares during the period from February 28, 2014 to February 28, 2021. Hill Spain also has the right to compel ("ESA Call Option") the minority shareholders to sell any or all of their shares during the same time period. The purchase price for such shares shall be seven times the earnings before interest and taxes for ESA's most recently ended fiscal year, net of any financial debt plus excess cash multiplied by a percentage which the shares to be purchased bear to the total number of shares outstanding at the time of purchase, but in the event the ESA Call Option is exercised by Hill Spain, the purchase price shall be increased by five percent. The ESA Put Option and the ESA Call Option must be made within three months after the audited financial statements of ESA have been completed.

        The Company is committed to issue shares of its common stock to the former shareholders of BCA in satisfaction of the Third Tranche Payment, the amount of which will be determined in mid-2014. See Note 3.

        The Company is committed to issue shares of its common stock to the former shareholders of CPI for certain contingent consideration. The number of shares will be determined at various times during 2014. See Note 3.

Other

        On December 31, 2012, the Company identified a potential employment tax liability related to certain foreign subsidiaries' treatment of certain individuals as independent contractors rather than as employees. On June 24, 2013, the Company received an indemnification from the selling shareholders for periods prior to 2013. Accordingly, the Company has reversed the accrual established in 2012 and has reflected approximately $3,600,000 as a credit to selling, general and administrative expenses in the consolidated statement of operations for the year ended December 31, 2013. In consideration for the indemnification, the Company reversed the 2013 first quarter write-down of the liabilities for the second installment obligation of approximately 1,950,000 BRL (approximately $873,000). In addition, the Company believes, based upon certain professional advice that it is remote that a future liability will be established for the potential employment taxes relating to certain foreign independent contractors and, therefore, has made no accrual for such potential liability.

Note 15—Operating Leases

        The Company has numerous operating leases which have various expiration dates through September 28, 2022. Rent expense was approximately $12,408,000, $12,538,000 and $13,329,000 for the years ended December 31, 2013, 2012 and 2011, respectively, which is included in selling, general and administrative expenses in the consolidated statements of earnings. The Company is required to pay property taxes, utilities and other costs related to several of its leased office facilities.

Effective January 1, 2013, the Company matches 50% of employee contributions up to 2% of employee compensation up to a maximum $2,550. For the years ended December 31, 2013, 2012 and 2011, the Company recognized expense amounting to $734,000, $666,000 and $1,828,000, respectively, which is included in selling, general and administrative expenses in the consolidated statements of earnings.

Note 17—Business Segment Information

        The Company's business segments reflect how executive management makes resource decisions and assesses its performance. The Company bases these decisions on the type of services provided (Project Management and Construction Claims) and secondarily by their geography (U.S./Canada, Latin America, Europe, the Middle East, Africa and Asia/Pacific).

        The Project Management business segment provides extensive construction and project management services to construction owners worldwide. Such services include program management, project management, construction management, project management oversight, troubled project turnaround, staff augmentation, project labor agreement consulting, commissioning, estimating and cost management, and labor compliance services.

        The Construction Claims business segment provides such services as claims consulting, management consulting, litigation support, expert witness testimony, cost/damages assessment, delay/disruption analysis, adjudication, lender advisory, risk management, forensic accounting, fraud investigation and Project Neutral services to clients worldwide.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
Hill International, Inc. and Subsidiaries

        We have audited the accompanying consolidated balance sheets of Hill International, Inc. and Subsidiaries (the "Company") as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive (loss) earnings, stockholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2013. The financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these financial statements based on our audits.

        We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Hill International, Inc. and Subsidiaries as of December 31, 2013 and 2012, and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2013 in conformity with accounting principles generally accepted in the United States of America.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Hill International, Inc. and Subsidiaries' internal control over financial reporting as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"), and our report dated March 14, 2014 expressed an unqualified opinion thereon.

        As discussed in Note 4 to the consolidated financial statements, the Company has significant accounts receivable from its operations in Libya. Since the end of the civil unrest in this country, the Company continues its collection efforts and is attempting to reestablish it operations. Due to these circumstances, if the Company is unable to collect these outstanding accounts receivable, the Company's financial condition could be significantly impacted.

        In connection with our audits of the consolidated financial statements referred to above, we also audited Schedule II—Valuation and Qualifying Accounts for each of the years in the three-year period ended December 31, 2013. In our opinion, this financial schedule, when considered in relation to the consolidated financial statements taken as a whole, presents fairly, in all material respects, the information stated therein.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders
Hill International, Inc. and Subsidiaries

        We have audited Hill International, Inc. and Subsidiaries' (the "Company") internal control over financial reporting as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission ("COSO"). The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit.

        We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

        A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

        In our opinion, Hill International, Inc. and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2013, based on criteria established in the 1992 Internal Control—Integrated Framework issued by COSO.

        We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Hill International, Inc. and Subsidiaries as of December 31, 2013 and 2012, and the related consolidated statements of operations, comprehensive (loss) earnings, stockholders' equity, and cash flows for each of the years in the three-year period ended December 31, 2013, and our report dated March 14, 2014 expressed an unqualified opinion thereon.

Quarterly Results (Unaudited)

        The following is a summary of certain quarterly financial information for fiscal years 2013 and 2012:

Item 9.    Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

        None.

Item 9A.    Controls and Procedures.

(a)

Evaluation of Disclosure Controls and Procedures.

        The management of the Company, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company's disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (the "Exchange Act")), as of December 31, 2013. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that, as of that date, the Company's disclosure controls and procedures were effective to provide reasonable assurance that information required to be disclosed in our reports under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms, and that such information is accumulated and communicated to management, including our Chief Executive Officer and our Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. During the quarter ended December 31, 2013, there were no changes in our internal control over financial reporting that materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.

        A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system will be met. Further, the design of a control system must reflect the fact that there are resource constraints and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if

any, within the company have been detected. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected. However, our disclosure controls and procedures are designed to provide reasonable assurance of achieving their objectives.

(b)

Management's Report on Internal Control over Financial Reporting.

        The Company's management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance of the reliability of financial reporting and of the preparation of financial statements for external reporting purposes, in accordance with U.S. generally accepted accounting principles.

        Internal control over financial reporting includes policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect transactions and disposition of assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with U.S. generally accepted accounting principles, and that receipts and expenditures are being made only in accordance with the authorization of its management and directors; and (3) provide reasonable assurance regarding the prevention or timely detection of unauthorized acquisition, use, or disposition of the Company's assets that could have a material effect on its financial statements.

        Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of the effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies and procedures included in such controls may deteriorate.

        The Company's management has assessed the effectiveness of the Company's internal control over financial reporting as of December 31, 2013. In making this assessment, the Company used the criteria established by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control—Integrated Framework (1992). These criteria are in the areas of control environment, risk assessment, control activities, information and communication, and monitoring. The Company's assessment included extensive documenting, evaluating and testing the design and operating effectiveness of its internal controls over financial reporting.

        Based on the Company's processes and assessment, as described above, management has concluded that, as of December 31, 2013, the Company's internal control over financial reporting was effective.

        EisnerAmper LLP, the independent registered public accounting firm that audited the consolidated financial statements in the Annual Report on Form 10-K for the year ended December 31, 2013, has issued an audit report concerning the effectiveness of our internal control over financial reporting for that year, which is included in Part II, Item 8 of this Form 10-K.

(c)

Changes in Internal Control.

        There were no changes in the Company's internal control over financial reporting during the Company's fourth quarter ended December 31, 2013, that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting.
