        A quorum is required to transact business The Trustee must receive your voting instructions no later than June 7, 2019. Please note that Plan participants may vote their shares through the Trustee only and accordingly may not vote their Plan shares in person at the annual meeting. We will have a quorumAnnual Meeting.

Receipt of Multiple Proxy Cards

Many of our stockholders hold their shares in more than one account and be able to conduct the businessmay receive separate proxy cards or voting instruction forms for each of the annual meeting if the holdersthose accounts. To ensure that all of a majority of theyour shares entitled to vote are present at the meeting, either in person or by proxy.

        If a quorum is present, a plurality of votes cast is required to elect directors. Thus, a director may be elected even if the director receives less than a majority of the shares represented at the meeting. Proxies cannot be voted for a greater number of nominees than are named in this Proxy Statement.

        All other matters to come before the annual meeting require the approval of a majority of the shares of common stock present, in person or by proxy, at the annual meeting and entitled to vote.

Table of Directors.

        Proxies marked as abstaining, and any proxies returned by brokers as "non-votes" on behalf of shares held in street name because beneficial owners' discretion has been withheld as to one or more matters to be acted upon at the annual meeting, will be treated as present for purposes of determining whether a quorum is present at the annual meeting. However, any shares not voted as a result of a marked abstention or a broker non-vote will not be counted as votes cast for or against a particular matter.Contents

How Can I Revoke My Proxy or Change My Vote?Revocation of Proxies

You can change your vote or revoke your proxy at any time before it is exercised at the Annual Meeting by timely deliverydoing any of the following: (1) you can submit a properly executed, later-datedvalid proxy with a later date; (2) you can notify our Secretary in writing at Secretary, Hill International, Inc., One Commerce Square, 2005 Market Street, 17th Floor, Philadelphia, Pennsylvania 19103 that you have revoked your proxy; or by voting(3) you can vote in person by written ballot at the meeting. ForAnnual Meeting.

Required Vote

Proposal 1: Election of Directors.    Our Board of Directors has determined that this year's election will be considered uncontested, so majority voting will apply to the election of directors at the Annual Meeting. Nominees receiving a majority of votes cast "for" their election will be elected as a director; the votes cast "for" a nominee must exceed the votes cast "withheld" for such nominee.

If you do not vote for a particular nominee, or if you indicate on your proxy card that you want to withhold authority to vote for a particular nominee, then your shares will not be voted for that nominee. If stockholders do not elect a nominee who is already serving as a director, Delaware law provides that the director would continue to serve on the Board as a "holdover director," rather than causing a vacancy, until a successor is duly elected or until the director resigns. In addition, if you hold beneficially in street name,shares of common stock through a broker-dealer, bank nominee, custodian or other securities intermediary, the intermediary will not vote those shares for the election of any nominee for director unless you may change your vote by submitting newgive the intermediary specific voting instructions on a timely basis directing the intermediary to vote for such nominee. Abstentions and broker non-votes do not constitute a vote "for" or "withheld" as to a director.

Pursuant to our Amended and Restated Bylaws, written notice by stockholders of qualifying nominations for election to our Board of Directors must have been received by our Secretary by March 23, 2019. We did not receive any such nominations, and no other nominations for election to our Board may be made by stockholders at the Annual Meeting.

If for some reason any of the Board's director nominees are unable to serve, the persons named as proxies may vote for a substitute nominee recommended by the Board and, unless you indicate otherwise on the proxy card, your shares will be voted in favor of the Board's remaining nominees. As of the date of the Notice of 2019 Annual Meeting of Stockholders, we knew of no reason why any of the Board's nominees would be unable or for good cause unwilling to serve as a director if elected.

Proposal 2: Advisory vote on the approval of the Company's named executive officer compensation.    The votes cast "for" this proposal must exceed the votes cast "against" such proposal for this proposal to pass. In addition, if you hold shares of common stock through a broker-dealer, bank nominee, custodian or other securities intermediary, the intermediary will not vote those shares either "for" or "against" the approval of the Company's named executive officer compensation unless you give the intermediary specific voting instructions on a timely basis directing the intermediary to vote. Abstentions and broker non-votes do not constitute a vote "for" or "against" this proposal and will be disregarded in the calculation of "votes cast."

Broker non-votes

A broker non-vote occurs when a beneficial owner of shares held by a broker, bank or other nominee followingfails to provide the instruction it has provided, or, if you have obtained a legal proxy from your broker or nominee giving you the rightrecord holder with specific instructions concerning how to vote your shares, by attendingon any "non-routine" matters brought to a vote at a stockholders meeting. Under the meeting and voting in person.NYSE rules,

Who Will Pay"non-routine" matters include the Expenseselection of Proxy Distribution?

        The Company will paydirectors (Proposal 1) and the expensesvote, on an advisory basis, on the approval of the preparationCompany's named executive officer's compensation (Proposal 2). Under applicable rules, a brokerage firm has the authority to vote shares on certain matters when their customers do not provide voting instructions; however, no such matters are to be voted upon at this year' Annual Meeting.

If you hold your shares in street name, it is critical that you cast your vote by instructing your bank, broker or other nominee on how to vote if you want your vote to be counted at the Annual Meeting for Proposals 1 and 2. Otherwise, your bank, broker or other nominee will not be able to vote your shares on these "non-routine" matters.

How to Attend the Annual Meeting

Registered stockholders may be admitted to the meeting upon providing picture identification. If you own shares in street name (i.e., your shares are held in street name through a broker, bank, trustee or other nominee), you must also bring your most recent brokerage statement, along with picture identification, to the meeting. We will use your brokerage statement to verify your ownership of common stock and admit you to the meeting.

Please note that cameras, sound or video recording equipment, or other similar equipment, electronic devices, large bags or packages will not be permitted in the Annual Meeting.

Quorum

A quorum of stockholders is necessary to transact business at the 2019 Annual Meeting. A quorum exists if the holders of at least a majority of the proxy materials and the solicitationshares of proxies. Proxies may be solicited on behalf of the Company by directors, officers or employees of the Company, who will receive no additional compensation for soliciting,common stock entitled to vote are present either in person or by telephone, e-mailproxy at the meeting. Abstentions and broker non-votes will be counted in determining whether a quorum exists.

2020 Stockholder Proposals

At each annual meeting, stockholders are asked to elect directors to serve on the Board. The Board or facsimilestockholders may submit other proposals to be included in the proxy statement. To be considered for inclusion in the 2020 Annual Meeting Proxy Statement, stockholder proposals must meet the requirements of SEC Rule 14a-8 and must be received no later than December 31, 2019. After such date, any shareholder proposal will be considered untimely and may be excluded from consideration at the meeting. Our Amended and Restated Bylaws provide that a stockholder may otherwise propose business for consideration or nominate persons for election to the Board, in compliance with federal proxy rules, applicable state law and other electronic means. In accordance withlegal requirements and without seeking to have the proposal or nomination included in our proxy statement. If our 2020 Annual Meeting is held no more than 30 days prior to and no later than 70 days after the anniversary date of our 2019 Annual Meeting, our Amended and Restated Bylaws currently require that notice of such proposals or nominations for our 2020 Annual Meeting be received by us during the period from February 12, 2020 to March 13, 2020. Any such notice must satisfy the other requirements in our Amended and Restated Bylaws applicable to such proposals and nominations.

CORPORATE GOVERNANCE

CORPORATE GOVERNANCE

Pursuant to the Delaware General Corporation Law and the Company's Amended and Restated By-laws,Bylaws, the Company's business, property and affairs are managed by or under the direction of the Board of Directors. Members of the Board are kept informed of the Company's business through discussions with the Chief Executive Officer and other officers, by reviewing materials provided to them and by participating in meetings of the Board and its committees. We currently have sevennine members on our Board.


Table of Contents

During 2014,2018, the Board held seven21 meetings and the committees held a total of ten24 meetings. Each incumbent director attended more than 75% of the total number of meetings of the Board of Directors and the Board committees of which he or she was a member during the period he or she served as a director in 2014.2018. Although we do not have a policy requiring all directors to attend annual meetings of stockholders, we expect all directors to attend, absent extenuating circumstances. AllEach of our directors attended the 2014our 2018 Annual Meeting of Stockholders.

Board Leadership Structure

Our Amended and Restated Bylaws provide that we will have a Chairman who will chair Board meetings and perform such other duties as set forth in our Amended and Restated Bylaws or as otherwise assigned to him by our Board. The Chairman and Chief Executive Officer may be the same person; however, our Board may separate these two positions if it deems it to be in the best interests of our Company and our stockholders to do so. Presently, the Chairman and Chief Executive Officer positions are held by two different individuals.

Role of the Board in Risk Oversight

The Board as a whole has responsibility for risk oversight, with reviews of certain areas conducted by relevant Board committees that report on their findings to the Board. The oversight responsibility of the Board and the Board committees is facilitated by management reporting processes designed to provide information to the Board concerning the identification, assessment and management of critical risks and management's risk mitigation strategies and practices. These areas of focus include operational, economic, competitive, financial (including accounting, reporting, credit, liquidity and tax), legal, regulatory, compliance, environmental, political and strategic risks. The full Board (or the appropriate Board committee), in concert with the appropriate management within the Company, reviews management reports to formulate risk identification, risk management and risk mitigation strategies. When a Board committee initially reviews management reports, the Chairman of the relevant Board committee briefs the full Board on the specifics of the matter at the next Board meeting. This process enables the Board to coordinate the risk oversight role, particularly with respect to risks spanning more than one operational area. The Compensation Committee reviews compensation policies to ensure that they do not, among other things, encourage unnecessary or excessive risk-taking.

Corporate Governance Guidelines

The Corporate Governance Guidelines adopted by the Board, which include guidelines for determining director independence, are published on the Company's website at www.hillintl.com, in the "Investors" section, and are available in print to any stockholder upon request. That section of the website makes available the Company's corporate governance materials, including Board committee charters. Those materials are also available in print to any stockholder upon request.

Committees of the Board of Directors

During 2018, the Board had standing Audit, Compensation, Risk and Governance and Nominating Committees. All members of each committee have been determined by the Board of Directors to be "independent" under applicable NYSE rules. In addition, the Board has determined that each member of the Audit Committee meets SEC independence requirements which require that members of the Audit Committee may not accept directly or indirectly any consulting, advisory or other compensatory fee from Hill or any of its subsidiaries other than their directors' compensation. The charter of each committee is available on our website at www.hillintl.com, in the "Investors" section.

Audit Committee

The Audit Committee currently consists of James Chadwick (Chair), Alan S. Fellheimer and Charles M. Gillman. The Board has determined that each member of the Audit Committee is financially literate. The Board has also determined that James Chadwick possesses accounting or related financial management expertise within the meaning of the NYSE listing standards and qualifies as an "audit committee financial expert," as defined by the rules of the SEC.

The Audit Committee assists the Board in fulfilling its oversight responsibilities by (a) reviewing the financial reports and other financial information provided by Hill to its stockholders, the SEC and others, (b) monitoring the Company's financial reporting processes and internal control systems, including the remediation of material weaknesses in internal control, (c) retaining Hill's independent registered public accounting firm, (d) overseeing the Company's independent registered public accounting firm and internal auditors and (e) monitoring the Company's compliance with its ethics policies and with applicable legal and regulatory requirements. The Audit Committee also reviews and approves any transactions between Hill and any related parties. During 2018, the Audit Committee met 8 times. The Audit Committee has been established in accordance with Section 3(a)(58)(A) of the Securities Exchange Act of 1934 (as amended, the "Exchange Act").

Compensation Committee

The Compensation Committee consists of Arnaud Ajdler (Chair), Alan S. Fellheimer and James Chadwick. Each member of the Compensation Committee is a "non-employee director" as defined in Rule 16b-3 of the Exchange Act and an "outside director" for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code").

The Compensation Committee oversees Hill's executive compensation programs. The Compensation Committee reviews and recommends to the Board for approval the compensation arrangements for all of the Company's executive officers. During 2018, the Compensation Committee met 12 times. The processes of the Compensation Committee are described below in "Compensation Discussion & Analysis."

Governance and Nominating Committee

The Governance and Nominating Committee consists of Camille S. Andrews (Chair), Arnaud Ajdler and Charles M. Gillman. The Governance and Nominating Committee oversees matters relating to the evaluation and recommendation to the Board of the persons to be nominated for election as directors at any meeting of stockholders, and the persons to be appointed by the Board to fill any vacancy on the Board.

The Governance and Nominating Committee is responsible for reviewing and assessing with the Board the appropriate skills, experience, and background sought of Board members in the context of our business and the then-current membership on the Board. This assessment includes a consideration of independence, diversity, age, skills, experience, and industry backgrounds in the context of the needs of the Board and the Company, as well as the ability of current and prospective directors to devote sufficient time to performing their duties in an effective manner. In March 2019, the Board adopted a diversity policy which formalized the guiding principles of the Governance and Nominating Committee in its recommendations of candidates to the Board, including seeking a balance in terms of knowledge and competencies of directors as well as seeking candidates for nomination to the Board who represent different genders, ages, cultural communities, geographic areas and other characteristics of the communities in which the Company conducts its business. This policy sets forth an aspirational target that at least 30% of the Board will be composed of women, ethnic minority and racially diverse individuals by June 2021.

The Governance and Nominating Committee carefully considers all director candidates recommended by our stockholders, and the Governance and Nominating Committee does not and will not evaluate such candidate recommendations any differently from the way it evaluates other candidates. The Company's Amended and Restated Bylaws set forth minimum qualifications for an individual to serve as a director of the Company. These minimum qualifications provide that no person shall qualify for service or serve as a director of the Company: (a) unless such person is in compliance with all applicable laws and regulatory requirements to which the Company's directors may be subject in connection with such person's service as a director, (b) if such person has been convicted in, or entered a plea of nolo contendere with respect to, a criminal proceeding involving fraud, misappropriation or other similar charge during the ten years preceding the date of election, or if such person has been found responsible for or admitted responsibility for fraud, misappropriation or other similar charge in any governmental investigation or proceeding or other civil judicial proceeding during the ten years preceding the date of election, or if such person has been found responsible for or admitted responsibility for any material violation of any foreign, federal or state securities law or federal commodities law during the ten years preceding the date of election, (c) if such person has been convicted of, or entered a plea of nolo contendere with respect to, any felony, (d) if such person serves on the board of directors of more than three other public companies, (e) if such person is a director, officer or holder of more than a five percent (5%) equity interest, directly or indirectly, in a business that competes, directly or indirectly, with the Company, (f) if such person has made or makes any contribution or expenditure in connection with the election of any candidate for political office, including any contribution to any committee supporting such a candidate or to a political party, in any jurisdiction which results in the Company becoming ineligible to conduct its business or any portion thereof, or (g) if such person has ever been the subject of a filing of personal bankruptcy in any jurisdiction, either voluntarily or involuntarily (and in the case of an involuntary filing, if such filing was not dismissed within 60 days) during the ten years preceding the applicable date of election.

Any stockholder who wishes to recommend an individual as a potential nominee for election to the Board should submit such recommendation in writing by mail to Hill International, Inc., One Commerce Square, 2005 Market Street, 17th Floor, Philadelphia, Pennsylvania 19103, Attn: Chair of Governance and Nominating Committee, together with information regarding the experience, education

and general background of the individual and a statement as to why the stockholder believes such individual to be an appropriate candidate for the Board of Directors of Hill. Such recommendation should be provided to Hill no later than the close of business on the 120th day prior to the one-year anniversary of the date the Company's proxy statement was released to stockholders in connection with the previous year's annual meeting. During 2018, the Governance and Nominating Committee held two meetings.

Risk Committee

The Risk Committee consists of Paul Evans (Chair), David Sgro and James Chadwick. The Risk Committee oversees matters regarding significant enterprise risks and other risks that may impact the Company's business and stockholder value as well as the processes that the Company uses to surface, understand and mitigate such risks. The Board established the Risk Committee in late 2018 and, during 2018, the Risk Committee met two times.

Majority Voting in Uncontested Elections of Directors

Our Bylaws provide for majority voting in uncontested elections of directors. Plurality voting applies in contested elections. A contested election is one in which the number of nominees exceeds the number of directors to be elected and other conditions are met. In an uncontested election, nominees will be elected directors if they receive a majority of the votes cast (i.e., the number of shares voted "for" a director must exceed the number of votes cast "withheld" from that director, without counting abstentions or broker non-votes); if a nominee is an incumbent director but is not elected, such director is required to tender his or her resignation to the Board promptly following the date of the certification of the election results. The Nominating and Governance Committee shall make a recommendation to the Board as to whether to accept or reject the tendered resignation, or whether other action should be taken. The Board shall act on the tendered resignation, taking into account the Nominating and Governance Committee's recommendation, and publicly disclose (by press release, filing with the SEC or other manner reasonably calculated to inform stockholders) its decision regarding the tendered resignation and the rationale behind the decision within 90 days from the date of the certification of the election results. In a contested election, the nominees who receive a plurality of the votes cast (i.e., more votes in favor of their election than other nominees) will be elected directors.

What We Do
What We Avoid
Pay for Performance — A significant portion of the compensation paid to our NEOs is related to performance and tied to pre-established performance goals and stock price aligned with our short- and long-term objectives.Excessive Perquisites — We provide very limited perquisites to our NEOs, other than our former CEO.
Target Market Median — Our compensation philosophy targets NEO total direct compensation opportunity that is competitive with the companies with which we compete for executive talent.No Speculative Trading — Board members and executive officers are prohibited from short-selling our stock and buying or selling puts and calls on our stock.

Robust Stock Ownership Guidelines — We require our directors and officers, including our NEOs to own multiples of their current base salary or annual cash retainer, as applicable. Our CEO is required to have six times (6x) his annual salary and our directors are each required to have three times (3x) their annual salary.No Repricing of Options/SARs — Our shareholder approved 2017 Equity Compensation Plan does not allow for the repricing of stock options/SARs without stockholder approval, and we have never repriced any stock option grants.
Severance Payments Require Double-Trigger — The Company's 2015 Senior Executive Retention Plan and its 2016 Executive Retention Plan provide change in control severance benefits only upon a double-trigger (change in control and termination of employment).No Unapproved Pledging of Hill Stock — The Company's insider trading policy prohibits pledging of Hill stock without review and prior approval by the Board. There are no current or open pledges of Hill stock by our current NEOs.

    1.    Target Annual Incentive Awards ("TAIA")

    In 2018, as in past years, the Committee evaluated the choice of the TAIA financial measure(s) using the following principles:

    Following this review, the Committee concluded that fosters executive retention in a manner that furthers Hill's mission of maximizing long-term stockholder value, client relationships, excellent financial performance, quality of service and employee satisfaction. That philosophy has been implemented in the past by placing substantial reliance on the payment of executive salaries at the higher end of the range of compensation received by executives with comparable job responsibilities at our peer companies, as well as through the use of year-end bonuses,a blend of metrics, including EBITDA, sales growth and key employee retention, for 2018 were appropriate measures to provide an emphasis on profitable growth while focusing managers on expense control and retaining key members of the Company's personnel.

    Target Setting

    The 2018 target annual incentive awards for Messrs. Ghali, Evans, Martinez and Griffin were set as appropriate, to reward superior performance and long-term incentive compensation elements to incentivize performance designed to lead Hill to success over a longer term.fixed dollar amount, as set forth below.

            For 2014, the Compensation Committee used various short and long-term performance-based compensation components within the mix of elements comprising the overall compensation packages paid to Hill's executive officers. The discussion that follows explains the manner in which the Compensation Committee applied these elements to develop the compensation policies and arrangements for our named executive officers.

    Compensation Philosophy and Objectives

            Performance.    Our Company's policy is that the Compensation Committee and the Board consider an executive officer's performance in determining his or her compensation. In addition, the Compensation Committee and the Board, in their discretion, may reward performance considered by the Compensation Committee to be superior, and may provide short-term incentives to executive officers to reward superior performance in cases where such performance would not otherwise be rewarded by other elements of Hill's compensation program.

    As of October 17, 2018, Mr. Martinez is no longer an employee of the rangeCompany and was not eligible to receive a TAIA Payment for compensation received by executives with comparable job responsibilities at our peer companies in addition to bonus and long-term incentive compensation. In addition, the Compensation Committee recognized the intense competition for talented senior executives in the sectors in which we operate and, in rewarding performance, focused closely on the need to retain the services of our other named executive officers who do not own significant equity interests in our Company. With respect to compensation decisions made in 2014, the Compensation Committee recognized that the prolonged economic downturn continued to place pressure on the Company's competitors to attract talented personnel, which heightened the need for our Company to set compensation in a manner designed to enable the Company to retain its most able executives even to the extent their ability to achieve superior performance for the Company might be hampered by economic conditions and other factors affecting the industries we serve. As a result, the Compensation Committee continued to rely on compensation policies designed to reward performance of these executives primarily by offering year-over-year base salary increases and by using bonus and long-term incentive awards primarily to reward extraordinary performance designed to reflect the overall growth and profitability of our Company as well as in the groups they manage. Measurements of growth and profitability for these purposes were made subjectively by the Compensation Committee with reference to budgets developed by management and approved by the Board of Directors, and without reference to any particular formula used to translate increases in perceived growth or profitability to specific compensation decisions.

            For 2014, the Compensation Committee continued to rely to an extent on the use of mathematical formulas in considering whether an individual executive's performance merited recognition through an award of periodic bonuses. Consistent with the policy established by the Compensation Committee in 2009, the Compensation Committee set formula-based targets for annual bonuses under the Hill International, Inc. 2010 Senior Executive Bonus Plan (the "Bonus Plan") as components of the total compensation packages received by our Chairman and Chief Executive Officer and our President and Chief Operating Officer for 2014. The Bonus Plan permits the Compensation Committee or the Board to award performance-based bonuses to our senior officers based on the achievement of performance goals established by the Compensation Committee or the Board in a manner designed to enable us to deduct for federal income tax purposes this bonus compensation consistent with Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code").

            The Compensation Committee believes it is of paramount importance to provide appropriate levels of compensation to our senior executives. Accordingly, the Compensation Committee may determine that the amount of a performance-based bonus award under the Bonus Plan is not sufficient to appropriately compensate or incentivize one or more senior executives for their performance with respect to the applicable performance period. In such event, the Compensation Committee may determine to award discretionary bonuses to senior executives, even if we are unable to deduct for federal income tax purposes the amount of the discretionary bonus. For 2014, the Compensation Committee awarded bonuses to each of our Chairman and Chief Executive Officer and our President and Chief Operating Officer under the Bonus Plan, which are described in more detail below. In connection with their compensation-related recommendations, our Chairman and Chief Executive Officer and our President and Chief Operating Officer recommended bonuses for our other named executive officers for 2014, and, consistent with their recommendation, the Compensation Committee determined awards of bonuses to our other named executive officers for 2014 which are described in more detail below.

    Mr. Levergood is eligible to receive a bonus based on generating new sales for the Company: for every $1,000,000 of expected consulting fee revenue generated by Mr. Levergood in a calendar year, Mr. Levergood will receive a $2,000 bonus, up to a maximum of $100,000. For 2018, Mr. Levergood did not earn a bonus related to this incentive. Mr. Levergood was also eligible to receive an additional bonus of $100,000 in the event that the Company achieves or exceeds its annual sales target; for 2018, the Company did not achieve its annual sales target so no related bonus was earned by Mr. Levergood.

    The Compensation Committee believes that alignmentBoard established a bonus pool. See the section titled "Compensation of other NEOs" for additional details regarding the bonus pool.

    Our Long-Term Equity Incentive Program

    Plan Criteria and Rationale

    Long-term incentive compensation offor all our executive officers, withincluding our NEOs, is entirely equity-based. In 2018, grants of Long-term Incentive Awards to Messrs. Ghali, Martinez, Griffin, Levergood, and Kardous are solely contingent upon the interestsachievement of growth targets in EPS over a three-year period.

    In this way, the combination of our stockholders through useAnnual Incentive Awards plan and Long-Term Incentive Awards balance the focus of stock-based incentive compensation is oneour team in a coordinated way around short-term financial, strategic and longer-term performance of our Company, both of which are directly linked to value creation for stockholders.

    Equity Award Grant Practices

    The Committee's equity-based awards policy contains rules on determining the grant date of equity awards and the performance based vesting criteria of such awards.

    2018 Long-Term Incentive Awards

    In 2018, for Messrs. Ghali, Martinez, Griffin, Levergood, and Kardous, the Board established Long-Term Incentive Award opportunities as an equity grant award which would convert to restricted stock units based upon the closing share price of the core principlesCompany's common stock on the date on which the Company becomes current on its SEC filings. These Long-Term Incentive Awards will vest 100% on the third anniversary of their grant and are performance-based, based on a targeted 10% Compound Annual Growth Rate ("CAGR") of a target Earnings Per Share over the vesting period.

    The value and form of each award was determined by the Committee after considering company performance, individual impact on our financial results, market norms and relative duties and responsibilities. The value of the grants made during 2018 to our NEOs are shown in the following table.

    Part 2 — Compensation Framework

    Compensation Philosophy and Objectives

    Our compensation philosophy is to provide competitive executive officers which are described in more detail below.

            Retention.    As discussed above, we recognize the intense competition for talented senior executives in the sectors in which we operate. Accordingly, retention ofofficer pay opportunities tied to our executive officers is one of the core objectives of our compensation philosophy. Historically, the Compensation Committee has sought to attain that objective primarily through the payment of base salaries at the higher end of the range of compensation that may be paid to executives at other companies within our industry. During 2014, the Compensation Committee continued to structure the named executive officers' total compensation so that each compensation element may be used to enable the Company to retain the services of our executive officers, consistent with our overall business strategy. As a result of this consideration, for 2014, the Compensation Committee decided to increase base salaries, make equity-based long-term incentive awards as well as award bonus compensation to all our named executive officers in a manner designed to enhance the utility of these components as tools to retain our most talented senior executives, which are described in more detail below.

            Risk Management Incentive.    The Compensation Committee believes that the compensation policies and practices it establishes should be designed with a view to incentivizing executives to achieve short-term and long-term success. This overriding pay-for-performance approach enables us to attract, motivate and retain the type of executive leadership that will help us achieve our strategic objectives and realize increased stockholder value. To reach these goals, we have adopted the following program objectives:

      Link management compensation with the interests and experience of stockholders.

      Support achievement of operating performance, goalsstrategic objectives and share price growth through variable compensation programs.

    Table of Contents

      Provide compensation opportunities that are consistent with each executive's responsibilities, experience and performance.

      Design compensation incentive programs that promote a sensible risk/reward balance, and that do not encourage unnecessary or unreasonable risk-taking.

    Applying our Compensation Philosophy

    We apply our compensation philosophy and objectives established by the Board while managing risks appropriately. The Compensation Committee attempts to provide both short-term and long-term compensation for current performance, as well as to provide incentives to achieve short-term and long-term goals. In designing these elements of compensation, the Compensation Committee seeks to incentivize appropriate levels of risk taking and to deter subjecting our Company to excessive risk.follows:

            Based on its understanding, as members of the Company's Board of Directors, of the elements of risk associated with our Company's business and the operations of each of our business units, the Compensation Committee does not believe that our Company's compensation policies and practices subject our Company

    Compensation Component

    Objectives
    Base SalaryFair and competitive compensation to attract, retain and reward executive officers by providing a fixed level of cash compensation tied to experience, skills and capability relative to undue risk. The Company's compensation policies and practices, and the elements of its compensation, are relatively consistent across the Company's business units. In the Compensation Committee's view, the risk profile for each of our Company's business units is relatively proportionate to its contribution to our Company's overall operating results. Other than our Company's Chairman and Chief Executive Officer and our President and Chief Operating Officer, no executive officer of the Company has an employment agreement with the Company. Accordingly, the Company's long-term payment obligation under employment agreements has been limited. In addition, as discussed below under "Elements of Compensation—Base Salary," while the employment agreements for our Chairman and Chief Executive Officer and our President and Chief Operating Officer target benchmarks for total compensation at the 75th percentile of the "selected peer group" identified by the market.
    Annual Incentive (Non-Equity) AwardCash bonus aligns executives with annual goals and objectives.

    Creates direct link to annual financial and operational performance.

    Provides the opportunity for NEOs to receive market-competitive total cash compensation when commensurate with performance.

    Long-Term Incentive AwardAligns executive officers' interests with those of stockholders by linking compensation with corporate performance that will lead to increased share price for our stockholders.

    Retains and provides incentives to executive officers through multi-year vesting and holding periods.

    Promotes a sensible balance of risk and reward, without encouraging unnecessary or unreasonable risk-taking.

    Provides the opportunity for NEOs to receive market-competitive TDC when commensurate with performance

    Setting Compensation Committee's view,Targets and Performance Goals

    The Committee annually reviews the methods used by our Company to compensate and incentivize our employees do not create risks that are reasonably likely to have a material adverse effect on our Company. In addition, while the Board has not adopted a specific policy with regard to the "clawback" of compensation awarded on the basis of improper conduct, the Compensation Committee recognizes that laws applicable to our Company generally require the "clawback" of compensation under circumstances relating to improper or illegal behavior. Accordingly, we believe that these laws support the Board's efforts to manage risk associated with compensation. The Board recognizes that the SEC plans to propose rules relating to compensation "clawback" policies and plans to enact policies to address the final rules that are adopted.

    Determining Compensation

            General.    In setting each element of compensation, the Compensation Committee has historically made qualitative assessments of the contributions made by each named executive officer toward our Company's achievement of its overall business and financial performance. These assessments have been employed by the Compensation Committee in determining which of the various compensation elements available to it should be included in each named executive officer's total compensation package, as well as the dollar amount thereof.

            Base salaries for our named executive officers are established by the Compensation Committee on an annual basis. When establishing base salaries for named executive officers who do not have employment agreements, the Compensation Committee takes into account the performanceopportunity of each named executive officer, his roleofficer-i.e., cash compensation (salary and responsibilities within our Company and the compensation of comparable executives at other publicly traded companies in our peer group. Under the terms of their respective employment agreements described below in "Employment Agreements," each of our Chairman and Chief Executive Officer and our President and Chief Operating Officer is entitled to receive base salary and antarget annual long-term equity-based incentive award, which, when aggregated with his target bonus which he will have the opportunity to earn based on the achievement of performance targets established annually by the Compensation Committee, is not less than the 75th percentile of the total base salary, bonusopportunity) and long-term incentive award earned by executivesequity compensation (target long-term equity value).

    The Committee, with comparable positions in our selected peer group companies. Our Compensation Committee believes that usinginput from its independent consultant, then sets the 75th percentile for comparative purposes reflects the high level of competency of our Company's senior executive officers.

            In establishing the base salaries to which our Chairman and Chief Executive Officer and our President and Chief Operating Officer are entitled under their respective employment agreements, the Compensation Committee considered the total annualexecutive's compensation of executives at similar levels in the companies included in the selected peer group listed below in "Selected Peer Group." The allocation between targeted annual cash incentive awards and long-term equity-based incentive compensation in order to achieve targeted total compensation at the benchmark level of the 75th percentile of the "selected peer group" companies was determined through direct negotiations between the Compensation Committee and each of our Chairman and Chief Executive Officer and our President and Chief Operating Officer. These negotiations focused on the need to reach agreement on the appropriate level of targeted annual cash incentive award for each executive, with reference to the prior year's bonus target for the executivecurrent year. Salary adjustments, if any, typically become effective as of January 1 of each year or upon a promotion. The compensation proposal for our CEO is reviewed with and the Company's internal budget, approvedratified by the Board of Directors, for 2014, without the use of any formula, weighting or reference to specific factors. The Compensation Committee's focus on determining the appropriate level of targeted annual cash incentive award relates primarily to the contingent natureindependent directors of the incentiveBoard in executive session.

    In making its decisions, the Committee uses several resources and tools, including competitive market information and peer group compensation trends, broader survey sources, the larger executive compensation environment, governance norms and expectations and shareholder feedback.

    For 2018, the Committee set target performance levels for the financial objectives used in the TAIA and concluded that it is earned only to

    Evaluating Performance

    For our other named executive officers, as in prior years, for 2014,eligible NEOs, performance determination under the Compensation Committee relied to a great extent on the assessments of their performance by our Chairman and Chief Executive OfficerTAIA and our President and Chief Operating Officer, to whom each of these other named executive officers reports. The Compensation Committee believes that this methodology allows us to account for all of the facts and circumstances of the particular executive officer's performance and enable us to most effectively reward, motivate, challenge and retain these named executive officers.

            The Compensation Committee recommended an increase in base salaries for our Chairman and Chief Executive Officer and our President and Chief Operating Officer to $1,400,000 and $1,000,000, respectively, in 2014. In addition, upon the recommendation of our Chairman and Chief Executive Officer and our President and Chief Operating Officer, the Compensation Committee recommended increases in base salaries for the other named executive officers in 2014 which are described in more detail below.

            In the first quarter of 2014, the Compensation Committee established targeted levels of bonus eligibility under the Bonus Plan for our Chairman and Chief Executive Officer and our President and Chief Operating Officer based partially on each of earnings before interest, taxes, depreciation and amortization ("EBITDA") for 2014, earnings per share for 2014 and debt reduction during 2014. The Compensation Committee selected these performance criteria for bonus eligibility under the Bonus PlanPool was 100% based on presentations by management to the Board concerning expectations for 2014 operating performance and related discourse among the Board and management during the first quarter of 2014.financial metrics. The Compensation Committee determined that these individuals would be eligible to earn 100% of their respective bonusalso considers competitive market norms in making final compensation targets if our Company reported EBITDA of at least $44,000,000 and diluted earnings per common share of at least $0.06 for 2014. Bonus eligibility was scaled so that a portion of the bonus compensation target would be awarded if part of an applicable target was achieved and a portion of the bonus compensation target would be earned if only one of the criteria was achieved. In addition, the Compensation Committee determined that our Chairman and Chief Executive Officer and our President and Chief Operating Officer would be eligible to earn additional bonus amounts if the Company's debt related to credit facilities was reduced by at least $10,000,000 during the year. For 2014, our Company reported EBITDA of $37,480,000 and a net loss of ($0.25) per common share and reduced its debt related to credit facilities by $16,546,000. Based upon the targets set by the Compensation Committee, these executives were each entitled under the Bonus Plan criteria and the reduction of debt goal to a bonus totalling $272,000.decisions.

    Role of the Compensation Committee and Management.Management

    The Compensation Committee reviews all of our Company's compensation and benefit programs. As part of its review of these programs, the Compensation Committee evaluates the competitiveness of compensation and benefits packages offered to our named executive officers and other executive officers. In addition, the Compensation Committee reviews and approves our corporate incentives, goals and performance objectives as well as the incentives, goals and performance objectives we establish for individuals under our Company's compensation and benefit programs. The Compensation Committee evaluates the level of achievement of the corporate incentives, goals and performance objectives set for individuals and, based on the level of achievement, approves any awards dependent on these criteria under our Company's compensation and benefit programs.

    Consistent with prior years, as part of the executive compensation decisions made in 2014,2018, our Chairman andformer Interim Chief Executive Officer and our President and Chief OperatingExecutive Officer made recommendations to the Compensation Committee regarding the levels and elements of compensation


    Table of Contents

    for the named executive officers, other than themselves, as well as for other executive officers of Hill. The Compensation Committee did not receive any compensation analysis regarding our named executive officers or Hill's other senior executive officers from any compensation consultant. After considering the recommendations of our Chairman and Chief Executive Officer and our President and Chief Operating Officer, the Compensation Committee delivered its recommendations to the Board for the Board's approval of the compensation elements and levels for the Chairman and Chief Executive Officer and the President and Chief Operating Officer, as well as for the other named executive officers. In determining its recommendations to the Board, the Compensation Committee relied considerably on assessments by our Chairman and Chief Executive Officer and our President and Chief Operating Officer of the performance and contribution of the other named executive officers.

            Selected Peer Group.    In 2012, the Compensation Committee identified our peer group and our "selected peer group" companies for compensation bench-marking purposes. The selected peer group includes CRA International, Inc., Exponent, Inc., Huron Consulting Group Inc. and Navigant Consulting, Inc.

            Noting that the public companies with which we compete for project management business tend to be significantly larger than Hill, the Compensation Committee concluded that those direct competitors would not be an appropriate group to use for purposes of analyzing the compensation paid to our Chairman and Chief Executive Officer and our President and Chief Operating Officer. Accordingly, the companies identified above provide services in consulting or other fields that are similar to the services we provide and were selected by the Compensation Committee on the basis of their size relative to us, and the presence within those companies and us of similar business model, cultural and philosophical elements. In addition, we recognize the companies in this group as those publicly traded companies with whom we compete most aggressively for talented executives. Accordingly, we refer to these companies as our "selected peer group" companies. In our most recent survey, the companies within the selected peer group had total annual revenues ranging between $272 million and $785 million.

            Equity Grant Practices.    The exercise price of each stock option granted to the named executive officers, as well as to our other named executive officers, was not less than the closing price of our common stock on the date of grant. Typically, the Board awards long-term equity-based incentives to our Chairman and Chief Executive Officer and our President and Chief Operating Officer annually and other executive officers, including the other named executive officers, in two-year cycles. In this regard, in January 2014, we awarded stock options to our Chairman and Chief Executive Officer and our President and Chief Operating Officer, and in March 2014 we awarded stock options to our other executive officers, including the other named executive officers. The awards for our Chairman and Chief Executive Officer and our President and Chief Operating Officer were based on the Compensation Committee's determination that these awards reflected the appropriate level of long-term equity based incentive for those individuals. In making this determination, the Compensation Committee did not make reference to any specific criteria. In determining the awards for our other named executive officers, the Compensation Committee relied upon recommendations from our Chairman and Chief Executive Officer and our President and Chief Operating Officer. The Compensation Committee expects to consider expanding the use of stock options and other equity-based awards in the future.

            We have not in the past and do not intend in the future to coordinate our grants of stock options with the release of material non-public information. We have not, as of the date of this proxy statement, adopted a policy covering compensatory equity grants. We also do not have a policy on the re-pricing of our stock options, but we have not previously re-priced any of our options. The equity compensation plan we use for awards to our named executive officers and other employees prohibits the repricing of options without stockholder approval.


    Table of Contents

    Elements of Compensation

            Base Salary.    The Compensation Committee aims to establish the base salary for each named executive officer at a level that is reflective of the level of responsibility assumed by that officer. For our Chairman and Chief Executive Officer and our President and Chief Operating Officer, total annual compensation is targeted at the 75th percentile of executive officers serving in comparable capacities with the companies included in our selected peer group. The Compensation Committee selected the 75th percentile as the benchmark for compensation of our two most senior executive officers as a result of their demonstrated leadership of our Company's efforts to establish and expand relationships key to our revenue growth and profitability, coupled with the Compensation Committee's view that these individuals are among the top executive talent in our industry and should be compensated accordingly. In view of the significant stock ownership in our Company by our Chairman and Chief Executive Officer and our President and Chief Operating Officer, the Compensation Committee historically has leaned more heavily on base salary than on equity-based compensation for these individuals. Accordingly, the base salaries of our Chairman and Chief Executive Officer and our President and Chief Operating Officer tend to be higher than those of comparably titled executives at companies in our selected peer group to reflect generally lower reliance by the Company on bonus and equity-based compensation elements. Equally relevant, the Compensation Committee recognizes that during the time it was a privately owned business, our Company typically did not award any bonus compensation or equity-based incentives to these individuals and, instead, concentrated compensation in the form of base salary. Since our Company's business became publicly owned, the Compensation Committee has sought to transition compensation practices to methods more commonly used by publicly traded companies, but has sought doing so without reducing the base salaries of our executive officers, including our Chairman and Chief Executive Officer, our President and Chief Operating Officer and our other named executive officers.

            The base salaries for our named executive officers are targeted at the higher end of our selected peer group and are adjusted to recognize varying levels of responsibility, individual performance, business segment performance, and internal Company issues. The Compensation Committee reviews each executive officer's base salary on an annual basis. During 2014, Hill's Chairman and Chief Executive Officer and its President and Chief Operating Officer were paid base salaries of $1,400,000 and $1,000,000, respectively. In its most recent survey of selected peer group of companies, the Company determined the base salaries paid to the chief executive officers within the selected peer group of companies ranged between $500,000 and $800,000 and the base salaries paid to the chief operating officers within the selected peer group of companies ranged between $450,000 and $600,000. For the reasons discussed above, the base salary levels for our Chairman and Chief Executive Officer and our President and Chief Operating Officer, relative to comparably titled executives at companies in our selected peer group, reflect our generally greater relative reliance on base salaries and lower relative reliance on bonus and equity-based compensation elements for these executives. Based on these factors, the Compensation Committee determined that the base salaries for our Company's Chairman and Chief Executive Officer and our President and Chief Operating Officer compared to the selected peer group benchmarks were appropriate and warranted. As explained above, consistent with prior years, in making executive compensation decisions for 2014, the Compensation Committee utilized recommendations of our Chairman and Chief Executive Officer and our President and Chief Operating Officer regarding the levels and elements of compensation for the named executive officers, other than themselves, as well as for other executive officers of Hill.the Company.

            The percentage increase for the Chairman and Chief Executive Officer reflect the Compensation Committee's determination to reward his strong leadership role and performance in the face of significant challenges affecting our industry. The relatively higher percentage increase for the President and Chief Operating Officer reflect the Compensation Committee's view of his high level of responsibility over the Company and its overall revenue as well as his individual performance. The percentage increase for our Senior Vice President and Chief Financial Officer reflects his important contributions to the Company in a key role.

            Annual Cash Incentive Awards.    The Compensation Committee and the Board, in their discretion, may establish annual cash incentives from time to time. Our objective in providing annual cash incentives is to reward short-term performance that has exceeded specific expectations in circumstances where no other element of our compensation program would otherwise reward such performance without incentivizing inappropriate risk-taking or otherwise deterring achievement of our long-term goals and initiatives. As stated above in "Determining Compensation—General," as a result of the Company's reported EBITDA and the reduction in debt during 2014, our Chairman andformer Interim Chief Executive Officer and our President and Chief OperatingExecutive Officer, were entitledthe Committee determined its recommendations to receive bonuses under the Bonus PlanBoard for 2014.the Board's approval of the compensation for our NEOs.

    Post-Employment Compensation Arrangements

            Long-Term Equity-Based Incentive Compensation.    From timeTermination Payments

    In the event of a change in control, we provide certain senior executive officers with benefits upon termination in various circumstances under our 2015 Senior Executive Retention Plan (the "2015 Retention Plan") and under our 2016 Executive Retention Plan (the "2016 Retention Plan" and, collectively with the 2015 Retention Plan, the "Retention Plans"). The Retention Plans provide change in control severance benefits only upon the occurrence of a "double-trigger" (change in control and termination of employment). Generally, the benefits under the 2015 Retention Plan provide for one year of salary and benefits continuation; the benefits under our 2016 Retention Plan provide for two years of salary upon termination following a change in control. As of December 31, 2018, there were no participants under the 2015 Retention Plan and Messrs. Ghali, Weintraub, Griffin and Kardous were eligible to time,receive benefits under the Compensation Committee and2016 Retention Plan.

    We detail the Board, in their discretion, may award long-term equity-based compensation estimated to be paid to our NEOs under various termination circumstances as of December 31, 2018 in the section below titled "Executive Officer Compensation — Potential Payments Upon Termination or Change in Control."

    Other Compensation Policies

    Personal Benefits

    We provide our NEOs with other benefits that we believe are reasonable and competitive so that we may attract and retain talented senior executives. In total, they represent a small percentage of each NEO's overall compensation and generally are identical to the benefits provided to all other Hill employees.

    Policy on Hedging and Pledging

    Our insider trading policy contains restrictions on certain transactions in Company stock by executive officers and directors. All trades by executive officers and directors must be pre-cleared. The executive officers and directors are prohibited from any trading in puts or calls, from engaging in short sales of Company stock or from hedging Company stock.

    executive officers, includingRisk Considerations in Our Compensation Programs

    The Committee has reviewed our named executive officers. In determining the termscompensation policies and amounts of any of these awards, the Compensation Committee seeks primarily to motivate successful multi-year operational and financial performance of our Company, to encourage long-term accountability of the individuals to whom the awards are made and to further reinforce the linkage between executive performance and creation of stockholder value.

            For 2014, the Compensation Committee recommended, and the Board approved, certain stock option awards for our named executive officers. The awards are shown in detail in the table under "Grants of Plan Based Awards" on page 25. As stated above in "Determining Compensation—Equity Grant Practices," the awards for our Chairman and Chief Executive Officer and our President and Chief Operating Officer were based on the Compensation Committee's determination that the awards reflected the appropriate level of long-term equity based incentive for those individuals. In making this determination, the Compensation Committee did not make reference to any specific criteria. In determining the awards for our other named executive officers, the Compensation Committee relied upon recommendations from our Chairman and Chief Executive Officer and our President and Chief Operating Officer.

            In our most recent survey, total long-term compensationpractices for the chiefCompany's executive officers and concluded that any risks arising from these policies and programs are not reasonably likely to have a material adverse effect. The Committee believes that the chief operating officersmix and design of the selected peer group of companies ranged between $292,000 and $1,096,000 and between $219,000 and $636,000, respectively.

    Compensation for Non-Employee Directors in 2014

            Non-employee directors' compensation is set by the Board at the recommendation of the Compensation Committee. For 2014, the Compensation Committee recommendedsufficient safeguards, balance and the Board approved a compensation and benefit program for non-employee directors. In developing its recommendations, the Compensation Committee was guided by the following goals: compensation should fairly pay directors for work required in order to serve on the Board and compensation should align non-employee directors' interests with the long-term interests of stockholders. For 2014, the Compensation Committee and the Board approved an annual compensation package for each non-employee director consisting of: (i) a $100,000 director's fee payable in cash, (ii) a grant of stock options, made at the meeting of our Board of Directors immediately following our annual meeting of stockholders, valued at $35,000 on the grant date, based on a Black-Scholes model, with immediate vesting and with an exercise price equal to the closing price per share of our common stock on the date of grant and exercisable over a five-year period, and (iii) an award on the same date of shares of our common stock valued at $35,000 based on the closing price per share of our common stock on the date of the award. In addition, the Chairman of the Compensation Committee and the Chairman of the Governance and Nominating Committee each receive an annual committee chairman's fee of $5,000 payable in cash, and the Chairman of the Audit Committee receives an annual committee chairman's fee of $10,000 payable in cash.

    Share Ownership Guidelines

            We have adopted a policy with respect to the ownership of our common stock by the members of our Board of Directors. Under our policy, each director is required to own at least 10,000 shares of our common stock. Each person is required to comply with the policy within two years after becoming subject to it. We dogovernance that does not have a policy with respect to the ownership of our common stockencourage excessive risk-taking by our executive officers.

    Tax Deductibility of Compensation

            We currently do not have a policy with respect to compliance with the limitations imposed by Section 162(m) of the Code, which imposes a $1,000,000 limit on the amount that a public company may deduct as an expense for compensation paid to our named executive officers.

            However, the Bonus Plan which was approved by stockholders in 2010 and is being presented to the stockholders for re-approval at the Annual Meeting is designed to preserve the tax deductibility of cash incentive awards to executive officers under Section 162(m) of the Code. As mentioned above, Section 162(m) generally limits to $1,000,000 per year the deductibility, for federal income tax purposes, of cash compensation to any individual who, as of the end of the year, is one of our named executive officers. This limitation does not apply to compensation that is deemed to be "qualified performance-based" within the meaning of Section 162(m). Therefore, if compensation qualifies as "qualified performance-based" for purposes of Section 162(m), we will be permitted to deduct it for federal income tax purposes. The provisions of Section 162(m) require, among other things, that the material terms of compensation plans such as our bonus award plans must be approved by a company's stockholders every five years in order for compensation awarded under such plan to qualify as "qualified performance-based." For additional information relating to the Compensation Committee's use of the Bonus Plan and, potentially, the award of other bonus compensation, see "Compensation Philosophy and Objectives—Performance."

    (2)
    In 2018, each of Messrs. Ghali, Martinez, Griffin, Levergood and Kardous were granted restricted stock units as Long-Term Incentive Awards which will vest on the third anniversary of their grant if certain performance goals related to Compound Annual Growth Rate ("CAGR") of a target Earnings Per Share over the vesting period is met. Because the Company did not estimate that the conditions under any of the performance level ranges would be met, there was no such compensation expense recorded for the year ended December 31, 2018.
    (3)
    The amounts reported in these columnsthis column reflect the aggregate grant date fair value of stock awards and grants of stock options calculated in accordance with Financial Accounting Standards Board Accounting Standards Codification Topic 718 ("ASC 718").718. The calculation of these amounts disregards the estimate of forfeitures related to time-based vesting conditions. The amounts in these columnsthis column do not reflect compensation actually

      received by the named executive officer. The actual value, if any, that an executive may realize from an award is contingent upon the satisfaction of the conditions to vesting in that award, and upon the excess of the stock pricepriced over the exercise price, if any, on the date the award is exercised. Thus, there is no assurance that the value, if any, eventually realized by the named executive officer will correspond to the amount shown.

    (2)(4)
    The Black-Scholes option valuation model is used to estimate the fair value of the options in accordance with ASC 718. For a discussion of the assumptions used, see Note 1112 to the Company's 2018 consolidated financial statements for 2014 containedincluded in thethis Annual Report on Form 10-K filed with the SEC on March 13, 2015.

The Company was not current with its SEC filings on the date that the RSUs were originally approved. In accordance with the terms of these grants, the RSUs could not be granted to the participants until the Company became current in its filings with the SEC. Therefore, these RSUs were granted and the value of the awards were estimated on October 12, 2018, the date the Company became current with its SEC filings. Because the Company did not estimate that the conditions under any of the performance level ranges would be met, there was no such compensation expense recorded for the year ended December 31, 2018. The total number of units issued under the awards totaled between approximately 226,000 and 678,000 had the Company estimated that the performance conditions could be met. As of October 17, 2018, Mr. Martinez is no longer an employee of the Company and accordingly the employment condition of his RSU is unable to be met, rendering the RSU invalid.

    To reasonably identify the median employee, the Company prepared a list of all employees (excluding the CEO) as of December 31, 2018. The list included part-time employees. As of December 31, 2018, the Company employed 2,725 persons (other than the CEO) of which 993 were located in the United States, 482 were located in Europe, 845 were located in the Middle East and 405 were located in other geographic areas. In certain geographic areas, such as the Middle East, compensation includes allowances (i.e., housing, travel, food, etc.) which are customary in such geographic areas.

    To identify the "median employee," the Company extracted the gross wages from the Company's payroll records as well as any allowances paid by the Company or paid the employee for each employee. The Company annualized wages and salaries for those permanent employees that were not employed for the full year of 2018.

    The Company then determined the employee on the list who had the median total compensation. The Company identified this employee as the median employee.

    Following this, the Company estimated the median employee's annual total compensation in the same manner as the "total" compensation shown for our CEO in the section titled "Summary Compensation Table." However, as our CEO only served as CEO for three months of 2018, for purposes of calculating his annual total compensation for 2018 for the pay ratio calculation, we annualized the salary which he is to receive for his services as CEO but did not annualize any other aspect of his total compensation for 2018; accordingly, there is a difference between our CEO's total compensation calculated for our the purposes of determining the pay ration and the total compensation for our CEO which appears in the section titled "Summary Compensation Table."

    2018 Pay Ratio

    The median employee's 2018 estimated annual total compensation was $65,648. The CEO's 2018 annual total compensation (as annualized) was $763,173. The ratio of the CEO to median employee's 2018 estimated annual total compensation was 12:1.

    Other than our former Interim CEO and our current CEO whose compensation as such is reflected on the Summary Compensation Table above, the table below details the compensation paid to our directors for their service as a descriptiondirector in 2018.

Also, the Chairman of the Board receives an additional annual retainer of $60,000, payable as $30,000 in cash and $30,000 in the form of deferred stock units. The Chairman of the Compensation Committee and the Chairman of the Governance and Nominating Committee each continue to receive an additional annual committee chairman's fee of $5,000 payable in cash, and the Chairman of the Audit Committee continues to receive an additional annual committee chairman's fee of $10,000 payable in cash.

    The amounts reported in these columns reflect the aggregate grant date fair value of stock awards, and grants of stock options and grants of deferred stock units ("DSUs") calculated in accordance with ASC 718. The amounts for options and DSUs do not reflect compensation actually received by the director. The actual value, if any, that a director may realize from an option award is contingent upon the excess of the stock price over the exercise price, if any, on the date the option is exercised.exercised; the actual value that a director may realize from a DSU is contingent upon the stock price on the date the DSU is settled following the termination of a director's service on the Board.

    Also on April 19, 2017, after reviewing proposals from several accounting firms, including EisnerAmper, the Audit Committee of the Board of Directors of the Company selected KPMG LLP ("KPMG") to be appointed following the filing of the Form 10-Q related to the fiscal quarter ended March 31, 2017 to serve as the Company's independent registered public accounting firm for the fiscal year ended December 31, 2017. During the two fiscal years ended December 31, 2016, and the subsequent interim period through March 31, 2017, the Company did not consult with KPMG regarding any of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.

    The audit report of EisnerAmper on the consolidated financial statements of Hill International, Inc. as of and for the years ended December 31, 2016 and 2015, did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles. The audit report of EisnerAmper LLP on the effectiveness of internal control over financial reporting for the Company as of December 31, 2016 and 2015 did conclude that internal controls over financial reporting were not effective due to identified material weaknesses.

    During the two fiscal years ended December 31, 2016, and the subsequent interim period through March 31, 2017, there were no: (1) disagreements with EisnerAmper on any matter of accounting


    Table of Contents

    principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to their satisfaction would have caused them to make reference in connection with their opinion to the subject matter of the disagreement, or (2) reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K), except that EisnerAmper advised the Company it agreed with the Company that certain deficiencies in the Company's internal control over financial reporting discussed with the Company during EisnerAmper's audits of the Company's consolidated financial statements for the years ended December 31, 2016 and 2015 constituted material weaknesses.

    On March 28, 2018, the Company dismissed KPMG as its independent registered public accounting firm. The decision to change independent registered public accounting firms was approved by the Audit Committee of the Company's Board of Directors (the "Audit Committee"). Also on March 28, 2018, the Audit Committee entered into an agreement with EisnerAmper to serve as the Company's independent registered public accounting firm. Such dismissal and appointment reflects the Audit Committee's belief that EisnerAmper, who served as the Company's independent public accounting firm during the restatement, will be able to complete the restatement as well as the audit of the Company's 2017 financial statements as expeditiously as possible. The Company consulted with EisnerAmper regarding the application of accounting principles in conjunction with the original audit and the restatement; however, the Company did not consult with EisnerAmper regarding any of the matters or events set forth in Item 304(a)(2)(ii) of Regulation S-K other than those related to the restatement.

    As disclosed in the Company's annual report on Form 10-K for the year ended December 31, 2018, management has identified certain deficiencies that rose to the level of a material weakness related to (i) failure to maintain effective controls over certain information technology systems and processes that are expectedrelevant to be present at the Annual Meetingpreparation of Stockholdersthe Company's consolidated financial statements, (ii) failure to maintain effective monitoring and review activities including the timely assessment of control design gaps and their impact to the control environment, (iii) failure to maintain effective controls over the financial reporting process, including the application of relevant accounting standards due to an inappropriate complement of personnel with the necessary level of accounting knowledge, experience, and training in the application of US GAAP commensurate with its financial reporting requirements and the complexity of the Company's operations and transactions, (iv) misapplication of US GAAP as it relates to the estimation of the potential loss on the Company's accounts receivable and related balances, (v) inadequate design or not having controls to accurately determine the Company's liability and ensure compliance with certain tax laws and employment regulations of the jurisdictions in which the Company operates, (vi) failure to maintain effective controls over the accurate preparation, recording, and review of foreign currency related transactions in accordance with ASC 830, Foreign Currency Matters, (vii) failure to maintain effective controls to ensure the accurate preparation and review of the cash flow statement in accordance with ASC 230, Statement of Cash Flows, (viii) failure to maintain effective policies, procedures, and controls to ensure that the revenue recognition accounting for certain customer contracts was performed in accordance with ASC 605-35, Revenue Recognition, (ix) failure to maintain effective controls over the monitoring of employee termination dates related to participants in the stock option program, and (x) failure to maintain effective controls over its income tax provision and related balance sheet accounts (collectively, the "Material Weaknesses").

    As a result of these Material Weaknesses, management concluded that, as of December 31, 2018, the Company's internal control over financial reporting was not effective.

    The Audit Committee of the Company's Board of Directors discussed the Material Weaknesses with EisnerAmper.

    REPORT OF THE AUDIT COMMITTEE

    AUDIT COMMITTEE REPORT

    The Audit Committee oversees the Company's financial reporting process on behalf of, and reports to, the Board. The Audit Committee has oversight of: (a) the integrity of the Company's financial statements; (b) the Company's compliance with legal and regulatory requirements; (c) the qualifications and independence of the Company's registered independent registered public accounting firm; (d) the Company's systems of internal controls established for finance, accounting, legal compliance and ethics; (e) the performance of the Company's registered independent public accounting firm; and (f) the integrity of the financial reports and other financial information prepared by the Company for submission to any governmental or regulatory body or the public. A more complete description of the duties and responsibilities of the Audit Committee is set forth in the Audit Committee's charter, which has been adopted by the Board. A copy of the Audit Committee Charter can be found in the Company's website atwww.hillintl.com, in the "Investors" section.


    Table of Contents

    Management of the Company has the primary responsibility for the financial reporting process (including establishing and maintaining adequate internal financial controls), for preparing the consolidated financial statements in accordance with U.S.U. S. generally accepted accounting principles, and for the report on the Company's internal control over financial reporting. EisnerAmper, the Company's independent registered public accounting firm for 2014,2018, is responsible for auditing those consolidated financial statements and expressing an opinion as to their conformity with U.S. generally accepted accounting principles and on the effectiveness of the Company's internal control over financial reporting.

    The Audit Committee has reviewed and discussed with management and EisnerAmper the audited financial statements for the year ended December 31, 20142018 and EisnerAmper's evaluation of the Company's internal control over financial reporting. The Audit Committee has discussed with EisnerAmper the matters that are required to be discussed by standards ofStatement on Auditing Standards No. 61, Communication with the Audit Committees, as amended (AICPA, Professional Standards, Vol. 1, AU section 380), as adopted by the Public Company

The Audit Committee has also reviewed and approved, among other things, the amount of fees paid to EisnerAmper for audit and non-audit services.

    PROPOSAL 2—RE-APPROVAL OF OUR 2010 SENIOR EXECUTIVE BONUS PLAN

    Other Matters

            The Board of Directors recommends that stockholders re-approve the Hill International, Inc. 2010 Senior Executive Bonus Plan ("Bonus Plan"). The purpose of asking stockholders to re-approve the Bonus Plan is so that incentive awards granted under the Bonus Plan may meet the requirements of tax-deductible qualified performance-based compensation under Section 162(m) of the Internal Revenue Code ("Section 162(m)"). Section 162(m) authorizes corporate tax deductions for certain executive compensation in excess of $1 million, if such compensation is paid under a performance plan and stockholders have approved the material terms of the performance plan at least once every five years. Stockholders previously approved the Bonus Plan in 2010, so approval is required in 2015 to meet the requirements under Section 162(m). If the Bonus Plan is not approved by stockholders, we would not be able to deduct any cash compensation over $1,000,000 that is awarded to any executive officer after 2014.

    Recommendation and Vote Required

            Approval of the proposal to re-approve the Bonus Plan will require the affirmative vote of the holders of a majority of the outstanding shares of our common stock represented in person or by proxy and entitled to vote at the meeting.


    OUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT OUR
    STOCKHOLDERS VOTE "FOR" THE PROPOSAL TO RE-APPROVE THE BONUS PLAN.

    Background

            The Board of Directors believes that our executive officers should be compensated through a mix of salary, bonus awards and long-term incentive compensation, and that this compensation should be tax-deductible by us to the largest extent possible. The Board of Directors and the Compensation Committee have determined that the Bonus Plan should be sufficiently flexible to allow the Compensation Committee to make awards in appropriate amounts and with appropriate performance periods and performance goals to whichever existing, new or recently promoted executive or other officers the Compensation Committee designates as plan participants. The Board of Directors and the Compensation Committee believe the Bonus Plan enables us to attract, retain, motivate and reward the exceptional level of leadership required for the continued success of the Company.


    Table of Contents

    Tax Deductibility

            The Bonus Plan is being presented to stockholders for re-approval in order to preserve the tax deductibility of cash incentive awards to executive officers under Section 162(m). Section 162(m) generally limits to $1,000,000 per year the deductibility, for Federal income tax purposes, of cash compensation to any individual who, as of the end of the year, is the chief executive officer of a public company or one of the other three most highly compensated executive officers (other than the chief financial officer). This limitation does not apply to compensation that is deemed to be "qualified performance-based" within the meaning of Section 162(m). Therefore, if compensation qualifies as "qualified performance-based" for purposes of Section 162(m), we will be permitted to deduct it for federal income tax purposes.

            The provisions of Section 162(m) require, among other things, that the material terms of compensation plans such as our bonus award plans must be approved by a company's stockholders every five years in order for compensation awarded under such plan to qualify as "qualified performance-based." The Company's stockholders last approved the Bonus Plan at the Company's Annual Meeting in 2010.

            Stockholder approval of the Bonus Plan is only one of several requirements under Section 162(m) that must be satisfied for amounts paid under the Bonus Plan to qualify as performance-based compensation. Even if stockholder re-approval is obtained under this proposal at the Annual Meeting, there can be no guarantee that amounts payable under the Bonus Plan will qualify as performance-based compensation.

            Below is a description of the material provisions of the Bonus Plan, in accordance with the stockholder approval requirements under Section 162(m). The complete text of the Bonus Plan can be found as Appendix A to the Company's Definitive Proxy Statement filed with the Securities and Exchange Commission on April 30, 2010, which text is incorporated herein by reference. The following description is qualified in its entirety by reference to the full text of the Bonus Plan.

    Material Provisions of the Bonus Plan

            The material provisions of the Bonus Plan are as follows:

            Participants.    The participants in the Bonus Plan are those officers designated as participants by the Compensation Committee for a given Performance Period (as defined in the Bonus Plan and described below). If the Bonus Plan is approved by stockholders, the Compensation Committee has designated that the participants for fiscal 2015 will be David L. Richter and Raouf S. Ghali.

            Performance Periods.    The Compensation Committee has the discretion to establish Performance Periods for Awards (as defined in the Bonus Plan and described below) under the Bonus Plan. Performance Periods may be equal to one of our full fiscal years, or may be longer or shorter than a full fiscal year. Multiple Awards may be granted to any participant.

            Awards.    Awards are payable to participants in the Bonus Plan based on the achievement of one or more pre-established performance goals. For each Award established under the Bonus Plan, prior to or within the first 90 days of the relevant Performance Period (or, if the Performance Period is shorter than a full year, within the first 25% of the Performance Period), in accordance with the requirements of Section 162(m), the Compensation Committee will establish one or more performance goals with respect to such Performance Period and an objective formula or method for computing the amount of the Award payable to each participant if the specified performance goals are achieved. The performance goals established by the Compensation Committee will be based on one or more of the business criteria set forth in the Bonus Plan (see below). At or after the end of each Performance Period, the Compensation Committee will determine whether and to what extent the performance goals have been achieved and will calculate the amount of the Award to be paid to each participant, if any,


    Table of Contents

    based upon the levels of achievement of the relevant performance goals and the objective formula or method established with respect to such Performance Period. The establishment of performance goals and the granting of Awards under the Bonus Plan will, in all cases, be implemented in a manner that is consistent with the requirements of Section 162(m) and the Treasury Regulations promulgated thereunder.

            Performance Goals.    The performance goals from which the Compensation Committee can set performance targets will relate to the achievement of financial goals based on the attainment of specified levels of one or more of the following: earnings per share, share price, market share, gross revenue, net revenue, net income, pre-tax income, pre-tax pre-bonus income, operating income, cash flow, collection of receivables, debt ratings, debt-to-capital ratio, generation of cash, enhancement of liquidity with respect to cash or cash equivalents, issuance of new debt, establishment of new credit facilities, retirement of debt, return on equity, return on assets, return on capital, return on revenues, attraction of new capital, net margin, pre-tax margin, total shareholder return, acquisition or disposition of assets, acquisition or disposition of entities or businesses, creation of new performance and compensation criteria for key personnel, recruiting and retaining key personnel, customer satisfaction, employee morale, hiring of strategic personnel, development and implementation of Company policies, strategies and initiatives, creation of new joint ventures, initiation, expansion, completion or other measures with respect to one or more projects or other business opportunities, increasing the Company's public visibility and corporate reputation, development of corporate brand name, overhead cost reductions, savings, productivity, or any combination of or variations on the preceding business criteria. The Board may specify any reasonable definition of the above business criteria. The performance goals established by the Board based on the above business criteria may be described in terms of objectives that are related to the individual participant or objectives that are Company-wide or related to any of its subsidiaries, operating divisions or other operating units and measured, where the Board deems appropriate, before or after any applicable unusual, unanticipated or non-reoccurring items, and may be measured in comparison to a budget approved by the Board, a peer group established by the Board or a stated target established by the Board.

            Cap on Awards.    Section 162(m) requires that the maximum potential Award amount payable under the Bonus Plan be disclosed to, and approved by, our stockholders, in order for any Award, regardless of its amount, to be tax-deductible by us. In order to ensure tax deductibility of all Awards under the Bonus Plan, the Compensation Committee has established that no Award payable under the Bonus Plan can exceed $1,500,000 (the "Award Cap"), and in no event will the maximum aggregate amount payable to any participant with respect to Awards that have Performance Periods that end in the same fiscal year exceed two times the Award Cap, regardless of the number of Awards that would otherwise be payable in that fiscal year (the "Annual Payment Cap"). Awards that are limited pursuant to the Annual Payment Cap may not be carried over and paid during a subsequent fiscal year. The Compensation Committee will have no discretion to increase the amount of any Awards beyond the Award Cap or the Annual Payment Cap, as applicable, but may, in its sole discretion, reduce the amount of an Award to any lesser amount, or set the Awards at any lesser amount, including as low as $0, based on such facts and circumstances as it deems relevant.

            Payment of Awards.    Awards under the Bonus Plan may be paid in cash, equity or a combination of the two. The equity portion of any Award under the Bonus Plan may be paid in shares of restricted stock, shares of unrestricted stock or restricted or unrestricted stock units, all of which will be issued from a plan adopted by the Board of Directors and approved by the Company's stockholders or a successor plan. To the extent an Award is settled with equity, such equity shall be valued as of the end of the Performance Period for the Award.

            Amendment and Termination of the Bonus Plan.    The Bonus Plan may be terminated or revoked by action of the Compensation Committee or the Board of Directors at any time. The Bonus Plan may be amended from time to time by the Compensation Committee, provided that no amendment may be


    Table of Contents

    made to the class of individuals who are eligible to participate in the Bonus Plan, the business criteria specified in the Bonus Plan or the maximum amount payable under the Bonus Plan without disclosure to and approval by our stockholders, unless stockholder approval is not required in order for the Award paid under the Bonus Plan to a covered employee (as defined in Section 162(m)) to constitute qualified performance-based compensation under Section 162(m). The Bonus Plan may be amended by the Compensation Committee as it deems appropriate in order to comply with the provisions of Section 162(m).


    OTHER MATTERS

    The Board is not aware of any matters other than those set forth in this proxy statement that will be presented for action at the annual meeting. However, if any other matter should properly come before the meeting, the persons authorized by the accompanying proxy will vote and act with respect thereto, in what according to their judgment is in the interests of Hill and its stockholders.
