This Notice of Annual Meeting, the Proxy Statement, and form of proxy or voting instruction form are being distributed and made available on or about April 21, 2023. To help manage costs and to reduce the environmental impact of the annual meeting process, the Annual Meeting will be a completely “virtual meeting” of stockholders. You will not be able to attend the Annual Meeting physically. Instead, you will be able to attend the Annual Meeting, as well as vote and submit your questions, during the live webcast by visiting www.virtualshareholdermeeting.com/ICFI2023 and entering the 16-digit control number included on your notice, proxy card or voting instruction form. Further details regarding the virtual meeting format can be found in the “Voting and Meeting” section of the Proxy Statement. We are pleased to utilize the U.S. Securities and Exchange Commission (the “SEC”) rule that allows companies to furnish their proxy materials to stockholders over the Internet. We believe that this allows us to provide you with all the information you need while lowering the costs of delivery for, as well as reducing the environmental impact of, our Annual Meeting. As a result, we are mailing to many of our stockholders a notice, instead of a paper copy, of our Proxy Statement and our Annual Report for the fiscal year ended December 31, 2022 (“2022 Form 10-K”). This notice contains instructions on how to access those documents over the Internet. We direct your attention to the attached Proxy Statement for more information, including instructions on how stockholders can receive a paper copy of our proxy materials, including our Proxy Statement, our 2022 Form 10-K and a form of proxy or voting instruction form. All stockholders who do not receive a notice, including stockholders who have previously requested to receive paper copies of proxy materials, will receive a paper copy of the proxy materials by mail unless they have previously requested delivery of proxy materials electronically. Employing an electronic distribution process will conserve natural resources and reduce the costs of printing and distributing our proxy materials. It is important that your shares of ICF International common stock be represented at the Annual Meeting in order to help ensure the presence of a quorum. Even if you plan to attend the Annual Meeting electronically via live webcast, please vote your shares of ICF International common stock by mailing your completed proxy or voting instruction form, or voting electronically or telephonically, as doing so will ensure your representation at the Annual Meeting regardless of whether you attend electronically via live webcast. Thank you for your cooperation and continued support of ICF International.

2022 Business Highlights

Financial Performance. All financial numbers referenced below were previously reported in the 2022 Form 10-K. Additional discussion of each of the metrics listed below can also be found in the 2022 Form 10-K.

In 2022 we won a record $2.3 billion in contract awards, laying the foundation for strong future growth. Revenue in 2022 amounted to $1.78 billion, representing 14.6% growth over the $1.55 billion reported for 2021. Service revenue increased 15.8% year-over-year to $1.29 billion, from $1.11 billion in 2021. 2022 net income amounted to $64.2 million, or $3.38 per diluted share, inclusive of $1.31 of tax-effected special charges, of which the overwhelming majority were facility, severance, and mergers & acquisitions-related charges. This compares to net income of $71.1 million reported in 2021, or $3.72 per diluted share, inclusive of $0.63 of tax-effected special charges, of which $0.57 represented facility and mergers & acquisition-related charges.

Total revenue increased 14.6% from $1.55 billion in 2021 to $1.78 billion in 2022. |  |  |  | Service revenue increased 15.8% year-over-year to $1.29 billion, from $1.11 billion in 2021. Service revenue is a non-GAAP measure and is calculated as U.S. GAAP revenue less subcontractor and other direct costs (which include third-party materials and travel expenses). A reconciliation of U.S. GAAP revenue to service revenue can be found on Page 45 of the 2022 Form 10-K.
Operating income decreased 2.0% from $110.9 million in 2021 to $108.8 million in 2022. |  |  |  | 2022 net income was $64.2 million, a decrease of 9.7% over $71.1 million in 2021.

Diluted earnings per share (“EPS”) was down 9.1% to $3.38 in 2022 compared to $3.72 in 2021, of which $1.31 represented tax-effected facility, severance, and mergers & acquisitions-related charges. |  |  |  | Non-GAAP EPS increased 19.7% from $4.82 in 2021 to $5.77 in 2022. Non-GAAP EPS represents diluted EPS, excluding the impact of certain items such as special charges and acquisition-related expenses that are not indicative of the performance of our ongoing operations, and the impact of amortization of intangible assets related to acquisitions and income tax effects. Non-GAAP EPS differs from other similar Non-GAAP EPS measures for annual incentive plans (see Annex A) and performance shares (see Annex B). A reconciliation of this Non-GAAP EPS can be found on Page 46 of the 2022 Form 10-K.

|  | COMPENSATION HIGHLIGHTS |  |

The Human Capital Committee of the Board (the “Human Capital Committee”) approved the following actions during fiscal year 2022 and at the beginning of fiscal year 2023, to maintain governance best practices and the pay-for-performance nature of our executive compensation program:

| ● |  | Continued utilizing performance-based share awards (“PSAs”) as a key component of ICF’s long-term incentive program. PSAs are performance contingent awards under which executives may earn shares depending on the Company’s actual performance against pre-established performance measures. The performance periods of the PSAs are long-term and further align executives’ interests with the interests of long-term stockholders.

| ● |  | Conducted an annual review to ensure compliance with stock ownership guidelines for our named executive officers (“NEOs”). As of April 3, 2023, each NEO met the stock ownership guidelines or is expected to meet the applicable stock ownership guidelines within the specified time period.

| ● |  | Continued the performance focus in the Company’s annual bonus program, referred to as the Annual Incentive Plan, rigorously linking pay to performance. Annual threshold, target and maximum performance goals were established with appropriate incentive payouts at each level.

| ● |  | Continued the annual review of NEO compensation against best practices and competitive market data.

| ● |  | Extensively reviewed external executive compensation trends to ensure that the Company’s executive compensation practices align with market best practices. The peer group data and other market data from nationwide salary surveys are used to provide a relevant basis for determining executive pay levels.

| ● |  | Supported the continuation of an annual, non-binding, advisory vote of the Company’s stockholders regarding the Company’s overall pay-for-performance named executive officer compensation program (“Say on Pay”). The Say on Pay vote at the Annual Meeting (Proposal 3) will be the thirteenth consecutive annual Say on Pay vote by stockholders.

For additional information on compensation related matters, see the Compensation Discussion & Analysis (the “CD&A”) section of this Proxy Statement, beginning on Page 50.

|  | CORPORATE GOVERNANCE HIGHLIGHTS |  |

ICF has a longstanding commitment to effective governance of its business and affairs for the benefit of its stockholders. The Board’s Governance and Nominating Committee (the “Governance and Nominating Committee”) periodically reviews our Corporate Governance Guidelines to maintain effective and appropriate standards of corporate governance.

BOARD LEADERSHIP STRUCTURE

Our Board leadership structure currently consists of a Chair of the Board (the “Chair”) who also serves as our CEO, a Lead Independent Director and independent committee chairs. The Board believes that ICF has been well served by combining the CEO and Chair positions, complemented by a strong and effective Lead Independent Director. The Board further believes that the current structure is in the best interests of the Company and its stockholders.

LEAD INDEPENDENT DIRECTOR

Dr. Srikant Datar was elected to serve as ICF’s Lead Independent Director, effective as of May 27, 2021. Both the Board and management believe that strong, independent Board leadership is a critical aspect of effective corporate governance.

Lead Independent Director responsibilities include, but are not limited to:

| ● |  | Chairing any meeting of the independent directors in executive session;

| ● |  | Facilitating communications between other members of the Board and the Chair; however, each director is free to communicate directly with the Chair;

| ● |  | Working with the Chair in the preparation of the agenda for each Board meeting and in determining the need for special meetings of the Board;

| ● |  | Consulting with the Chair on matters relating to corporate governance and Board performance;

| ● |  | Leading the deliberation and action by the Board or a Board committee regarding any offer, proposal or other solicitation or opportunity involving a possible acquisition or other change in control of the Company, including by merger, consolidation, asset or stock sale or exchange, or recapitalization;

| ● |  | In conjunction with the Chair of the Governance and Nominating Committee, overseeing and participating in the annual board evaluation and succession planning process;

| ● |  | Participating in the Human Capital Committee’s annual performance evaluation of, and succession planning for, the Chair, President and CEO; and

| ● |  | Meeting with any director whom the Lead Independent Director deems is not adequately performing his or her duties as a member of the Board or any committee.

BOARD COMMITTEES

The three (3) standing committees established by the Board meet on a regular basis and operate under written charters approved by the Board. Each committee performs an annual self-evaluation to determine whether the committee is functioning effectively and fulfilling its duties, as prescribed by its charter. All members of the Audit Committee of the Board (the “Audit Committee”), the Human Capital Committee and the Governance and Nominating Committee are independent, and each committee has the ability to hire and terminate its own outside advisors.

BOARD RISK OVERSIGHT

Management is responsible for the day-to-day management of the risks we face, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. Our Board meets regularly to discuss the strategic direction of, and the issues and opportunities facing our Company. Our Board provides guidance to management regarding our strategy, including in connection with our results of operations and related trends and factors contributing to or affecting our results, long-term strategy, financial reporting and risks associated with these aspects of the Company’s business. The involvement of the Board in setting our business strategy is an important part of determining the types and appropriate levels of risk undertaken by the Company. Management conducts regular enterprise risk assessments, which include feedback from the Board, to ascertain and define the most significant risks facing the Company. After assessments are complete, management reports regularly to the Board and Board committees on the status and completion of actions associated with the most significant risks.

We have also established a Code of Business Ethics and Conduct (the “Code of Ethics”) that establishes standards of conduct and expectations for our employees and the overall manner in which we conduct business. The Code of Ethics, along with our other policies and business standards, and our overall risk and compliance programs are components of mitigating the risks associated with the operation of our business.

CONTINUING EDUCATION

ICF’s Corporate Governance Guidelines encourage all directors to receive continuing education in areas that will assist them in discharging their duties. The Governance and Nominating Committee routinely reviews education opportunities available for Board members and has identified a series of courses and programs suited to the Directors’ service on the Board and Board committees.

STOCK OWNERSHIP AND HOLDING PERIOD REQUIREMENTS

The Board believes that designated executives of the Company should have a financial stake in ICF so that their interests are aligned with those of the stockholders and will cause them to more effectively represent ICF’s stockholders. The 2018 Executive Stock Ownership Policy, as amended, requires executives to own ICF common stock in a value equal to, or in excess of, the multiple of their annual base salary as follows:

|  | ●Executive Chair:* |  | 5x |  |
|  | ●CEO: |  | 5x |  |
|  | ●Other NEOs: |  | 2x |  |
|  | ●Other designated executives: |  | 1x |  |

*While the policy references an Executive Chair, that position is currently vacant and we do not currently intend to fill that position.

Stock ownership levels are to be achieved within five (5) years of appointment or designation, as the case may be, for executives. For executives appointed or designated mid-year, such levels, if not achieved by their fifth anniversary of becoming such an executive, are to be achieved no later than December 31 of that fifth year.

The Board also believes that its own members should share stockholders’ focus on the Company’s long-term value. As such, the Board adopted a Board member stock ownership policy establishing, as a guideline, that each non-employee director of the Company be expected to own shares of Company common stock valued at five (5) times such director’s annual cash retainer fees, which may include shares of unvested restricted stock (i.e., directors are strongly encouraged to hold common stock valued at $425,000). Such ownership level is to be achieved over a period of four (4) years after becoming a member of the Board.

As of April 3, 2023, each of our NEOs and non-employee directors either met the above stock ownership guidelines or is expected to meet the applicable ownership guidelines within their respective specified time period.

ANTI-HEDGING AND ANTI-PLEDGING

Pursuant to the Company’s Policy on Insider Information and Securities Trading (“Policy on Insider Information”), the Company considers it improper and inappropriate for any employee, officer or director of the Company to engage in short-term or speculative transactions in the Company’s securities. The policy specifically prohibits directors, officers, and other employees from engaging in short sales of the Company’s securities and transactions in puts, calls or other derivative securities (sometimes referred to as “hedging”). Each of the NEOs and directors complied with the Policy on Insider Information during fiscal year 2022.

Previously, individual stock grant agreements prohibited the pledging or assignment of stock grants. In April 2020, the Company adopted an updated and more comprehensive Hedging and Pledging Transactions Policy (the “Hedging and Pledging Policy”) which is applicable to our directors, Section 16 reporting officers and other designated officers of the Company, which was further updated in September 2020. The policy establishes a restriction on short sales and other hedging transactions, pledging and the establishment of margin accounts. In addition, stock grant agreements prohibit the pledging or assignment of awards.

Directors and other covered officers who established pledging arrangements within the prior limitations will be prohibited from establishing new arrangements and are encouraged to wind down and conclude any legacy arrangements. There are currently no directors with any legacy pledging arrangements in place.

BOARD EVALUATION

The Directors participate in an annual evaluation of the full Board and each committee on which they serve in order to assess the performance and effectiveness of the Board and its committees. The responses and comments are presented to and discussed with the Board and each committee of the Board. In addition, every two years, the Lead Independent Director and the Chair of the Governance and Nominating Committee supplement the annual evaluation process with individual meetings and peer evaluations with each Director. The last supplemental evaluation was conducted in 2022. These supplemental discussions are intended to enhance the existing Board evaluation process and foster even greater discussion regarding the adequacy and effectiveness of the Board and such committees.

Additionally, the Board has conducted and plans to continue to periodically conduct external evaluations by an independent third party. The external evaluations would include interviews with directors and may include interviews with key management personnel, to determine existing strengths of the Board, as well as areas of improvement, to increase overall Board effectiveness.

COMPENSATION RECOUPMENT POLICY

The Company’s basic recoupment policy is set forth in the 2018 Omnibus Incentive Plan, as amended (the “2018 Incentive Plan”), and is emphasized and enhanced through individual severance arrangements with NEOs. Under the recoupment policy, if any of the Company’s financial statements are required to be restated due to errors, omissions or fraud, the Human Capital Committee may direct that the Company recover all, or a portion of, any award (cash or equity) granted or paid to a participant, with respect to the fiscal year which is negatively affected. If so directed, the amount to be recovered from the participant shall be the amount by which the award exceeded the amount that would have been payable to the participant had the financial statements been initially filed as restated, or any greater or lesser amount (including, but not limited to, the entire award) that the Human Capital Committee shall determine. In no event shall the amount to be recovered by the Company be less than the amount required to be repaid or recovered as a matter of law (including but not limited to amounts that are required to be recovered or forfeited under Section 304 of the Sarbanes-Oxley Act of 2002).

Severance agreements for Messrs. Morgan, Broadus, Lee and Ms. Choate further define and expand the Company’s recoupment rights. The agreements provide that, except following a change of control, the Company has “clawback” rights with respect to “Excess Incentive Awards” arising from an expanded list of “Clawback Events” as defined in the agreements. Except in situations involving fraud (as to which the statute of limitations will apply), the Human Capital Committee may, within three years after the latest to occur of a Clawback Event or harm to the Company, determine and recommend to the Board (acting in its sole discretion, but in good faith) that the Company recover (including, without limitation, through forfeiture) all or a portion of any incentive compensation (including short-term Annual Incentive Plan incentive awards and long-term (equity) incentive awards) that was granted after the date of the agreement, based wholly or in part on a financial reporting, stock price or similar shareholder return measure under an incentive compensation plan or other incentive compensation arrangement with respect to any of our fiscal years that were negatively affected by such events or matters. Equity awards that were granted before the date of the new agreements and are based wholly or in part on a financial reporting, stock price or similar shareholder return measure, as well as equity awards that vest based on the passage of time, are excluded from the operation of the new clawback provisions.

On October 26, 2022, the SEC adopted Rule 10D-1 to the Exchange Act to implement the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (the “Dodd-Frank Act”). Rule 10D-1, directs the national securities exchanges and associations (including our own securities exchange, NASDAQ) to establish listing standards requiring each listed issuer to implement policies providing for, in the event of certain accounting restatements, the recovery of incentive-based compensation received by current or former executive officers to the extent such compensation was based on erroneously reported financial information. If Proposal 2 of this Proxy Statement is approved by our shareholders, the 2018 Incentive Plan will be amended and restated to, among other things, include updated compensation recovery provisions that coordinate with the requirements of Rule 10D-1, in the expectation that NASDAQ’s listing standards under Rule 10D-1 will become effective no later than November 2023. Additionally, once the final NASDAQ listing standards have been approved, the Company anticipates it will adjust its compensation recovery arrangements to further coordinate with Rule 10D-1, including through the adoption of a clawback policy for that purpose.

You will find important information in this Proxy Statement about the qualifications and experience of each of the director nominees whom you are being asked to elect. The Governance and Nominating Committee performs an annual assessment to evaluate whether ICF’s directors have the skills and experience to effectively oversee the Company. Each of our director nominees is a current director of the Company and has demonstrated leadership ability, sound judgment, integrity and a commitment to the success of our Company.

APPROVE THE AMENDED AND RESTATED ICF INTERNATIONAL, INC. 2018 OMNIBUS INCENTIVE PLAN (PROPOSAL 2)

Stockholders are being asked to vote in favor of an amendment and restatement of the 2018 Incentive Plan to (1) increase the total number of shares authorized for issuance under the plan by 450,000 shares to a total of 2,050,000 shares; (2) incorporate provisions allowing for compensation recovery consistent with the requirements of Rule 10D-1 of the Securities Exchange Act of 1934, as amended, and exchange listing standards to be adopted thereunder by NASDAQ; (3) rename the plan as the “Amended and Restated ICF International, Inc. 2018 Omnibus Incentive Plan”; and (4) make certain other non-substantive amendments intended to clarify various plan provisions. The proposal was approved by the Board on April 5, 2023. The Amended and Restated ICF International, Inc. 2018 Omnibus Incentive Plan will be considered effective if and when approved by our stockholders at the Annual Meeting.

Detailed information on Proposal 2 can be found on pages 16 through 22 in this Proxy Statement and a copy of the Amended and Restated ICF International, Inc. 2018 Omnibus Incentive Plan is attached as Exhibit A to this Proxy Statement.

PROVIDE AN ADVISORY VOTE REGARDING ICF INTERNATIONAL’S OVERALL PAY-FOR-PERFORMANCE NAMED EXECUTIVE OFFICER COMPENSATION PROGRAM (PROPOSAL 3)

Stockholders are being asked to cast a non-binding, advisory vote on our overall pay-for-performance NEO compensation program. Last year, approximately 97% of the votes cast by our stockholders supported ICF’s overall pay-for-performance executive compensation program. In evaluating this year’s Say on Pay proposal, we recommend that you carefully review the CD&A section of this Proxy Statement which explains how and why the Human Capital Committee arrived at its executive compensation actions and decisions for 2022.

PROVIDE AN ADVISORY VOTE REGARDING ICF’S FREQUENCY OF SAY ON PAY VOTING (PROPOSAL 4)

Stockholders are being asked to cast a non-binding, advisory vote (commonly known as a “Say When on Pay” or “Say on Frequency” vote) on how frequently the Company’s stockholders are given an opportunity to cast a “Say on Pay” vote at future annual stockholder meetings (or any special stockholder meeting for which ICF must include executive compensation information in the proxy statement for that meeting). Under this Proposal 4, you may vote to have a “Say on Pay” vote take place every year, every two years or every three years. The Board recommends continuing to hold an annual Say on Pay vote.

AMEND THE ICF INTERNATIONAL AMENDED AND RESTATED CERTIFICATE OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OFFICERS OF ICF (PROPOSAL 5)

Stockholders will be asked to consider a proposal to approve an amendment to the Certificate of Incorporation of the Company (the “Charter”) to provide exculpation from liability for officers of the Company from certain monetary claims of breach of the fiduciary duty of care, similar to protections currently available to directors of the Company.

Detailed information on Proposal 5 can be found on pages 25 through 26 in this Proxy Statement.

RATIFY THE SELECTION OF GRANT THORNTON LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR FISCAL YEAR 2023 (PROPOSAL 6)

The Audit Committee has appointed, and the Board has approved the appointment of, Grant Thornton as the Company’s independent registered public accounting firm (“independent auditor”) for fiscal year 2023. While we are not required to have stockholders ratify the selection of Grant Thornton as the Company’s independent auditor, we are doing so because we believe it is good corporate governance practice. If stockholders do not ratify the selection, the Audit Committee will reconsider the appointment, but may nevertheless retain Grant Thornton as the Company’s independent auditor. Even if the selection is ratified, the Audit Committee may, at its discretion, direct the appointment of a different independent auditor at any time during the year if it determines that such change is in the best interests of the Company and its stockholders.

In addition to complying with the procedures described above, stockholders who intend to solicit proxies in support of a director nominee other than the Company’s nominees for consideration by the stockholders at the Company’s 2024 annual meeting of stockholders must also comply with the SEC’s “universal proxy card” rules under Rule 14a-19 of the Exchange Act (“Rule 14a-19”).

##### Table of Contents

|  | VOTING AND MEETING INFORMATION

How does the Board recommend that I vote?

Our Board recommends that you vote your shares: (i) FOR the nominees for election to the Board; (ii) FOR Proposals 2, 3, 5 and 6, and (iii) EVERY YEAR for Proposal 4.

Who is entitled to vote?

Holders of record of our common stock as of the close of business on April 3, 2023, are entitled to vote at the Annual Meeting. At that time, we had 18,788,082 outstanding shares of common stock. We have no other outstanding classes of stock that are entitled to vote at the Annual Meeting. Voting stockholders are entitled to one (1) vote per share.

Why did I receive a notice in the mail regarding the Internet availability of the proxy materials instead of a paper copy of the proxy materials?

We are pleased to utilize the U.S. Securities and Exchange Commission (the “SEC”) rule that allows companies to furnish their proxy materials over the Internet. As a result, we are mailing to many of our stockholders a notice about the Internet availability of the proxy materials instead of a paper copy of such materials. All stockholders receiving the notice will have the ability to access the proxy materials over the Internet and to request a paper copy of the proxy materials by mail.

To reduce the expense of delivering duplicate notices to stockholders, we are relying upon SEC rules that permit us to deliver only one (1) set of the proxy materials to multiple stockholders who share an address. We send a separate notice to each stockholder about this option, and we will deliver (a) a separate copy of the proxy materials to any stockholder at a shared address who requests his or her own copy or (b) a single copy if multiple copies are sent to one address and the stockholders who share the address would like to receive only a single copy. Requests should be made to ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia 20190, Attention: Corporate Secretary, phone number (703) 934-3000.

How can I access the proxy materials over the Internet?

Your notice about the Internet availability of the proxy materials, proxy form, or voting instruction form will contain instructions on how to view our proxy materials for the Annual Meeting on the Internet. Our proxy materials are also publicly available, free of charge, at www.proxyvote.com. Our proxy materials will be available at this website through the conclusion of the Annual Meeting.

Your notice of Internet availability of proxy materials, proxy form, or voting instruction form will contain instructions on how you may request access to proxy materials electronically on an ongoing basis. Choosing to access your proxy materials electronically will help us conserve natural resources and reduce the costs of printing and distributing our proxy materials.

How may I obtain a paper copy of the Company’s proxy materials, 2022 Form 10-K, and/or other financial information?

Stockholders receiving a notice about the Internet availability of the proxy materials will find instructions regarding how to obtain a paper copy of the proxy materials on their notice. Stockholders also may request a free copy of this Proxy Statement and/or our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 1, 2023 (the “2022 Form 10-K”), by writing to: ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia 20190, Attention: Corporate Secretary. Alternatively, stockholders can access our 2022 Form 10-K on our Investor Relations website at: http://investor.icf.com. We will also furnish any exhibit to the 2022 Form 10-K, if specifically requested.

How do I vote?

You may vote electronically via live webcast at the Annual Meeting, or in advance of the Annual Meeting on the Internet, by telephone, or through a proxy or voting instruction form. Stockholders who have received a notice of the availability of the proxy materials by mail may submit proxies over the Internet by following the instructions on the notice. Stockholders who have received a paper copy of a proxy form or a voting instruction form by mail may either:

| (i) | submit their proxy over the Internet using their computer or by telephone by following the instructions on the proxy form or voting instruction form; or

| (ii) | submit their proxy by mail by signing and dating the proxy form or voting instruction form received and returning it in the prepaid envelope.

What if I hold shares indirectly?

If you hold shares in a stock brokerage account, or through a bank or other nominee, you are considered to be the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by your broker, bank or nominee. As the beneficial owner, you have the right to direct your broker, bank or nominee how to vote. If you do not direct your broker, bank or nominee how to vote, it is permitted to vote your shares on the ratification of the selection of the independent registered public accounting firm, even if you do not furnish voting instructions; however, it will not be able to vote on other matters.

If your shares are held in street name, your broker, bank or other nominee may have procedures that will permit you to vote by telephone or electronically through the Internet.

Can I change my vote?

You have the right to revoke your proxy at any time before votes are counted at the Annual Meeting by:

| ● |  | voting electronically via live webcast at the Annual Meeting;

|  | 2

##### Table of Contents

|  | VOTING AND MEETING INFORMATION

| ● |  | entering a new vote by using the Internet or the telephone, or by mailing a new proxy form or new voting instruction form bearing a later date, which will automatically revoke your earlier voting instructions; or

| ● |  | notifying us at our corporate offices by writing to ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia, 20190, Attention: Corporate Secretary.

Attendance at the Annual Meeting via attending the webcast will not in itself constitute revocation of your proxy.

Attending the Annual Meeting

Attendance at the Annual Meeting is limited to stockholders who, as of the record date, are:

| ● |  | stockholders of record;

| ● |  | beneficial holders of ICF International common stock held by a broker, bank or other nominee; or

| ● |  | authorized representatives of entities who are record or beneficial holders.

You may log in 15 minutes before the start of the Annual Meeting to test your Internet connectivity. You can vote and submit questions while attending the meeting online.

How do I submit questions and vote electronically?

If you encounter any difficulties accessing the virtual meeting during the check-in or meeting time, please call the technical support line number that will be posted on the Virtual Shareholder Meeting login page.

What are the requirements and procedures for a quorum, abstentions, and broker non-votes?

Your shares are counted as present at the Annual Meeting if you attend the meeting electronically, if you properly return a proxy by mail, if you vote by telephone or electronically, or if you hold your shares in street name and your broker, bank or other nominee votes your shares on Proposal 6. In order for us to vote on matters at the Annual Meeting, a majority of our outstanding shares of common stock as of April 3, 2023, and entitled to vote must be present electronically via live webcast or by proxy at the Annual Meeting. This is referred to as a quorum. Abstentions will be counted for purposes of establishing a quorum at the meeting

and will be counted as voting on the affected proposal. Broker non-votes will be counted for purposes of establishing a quorum but will not be counted as voting. A broker non-vote occurs when a broker, bank, or other nominee holding shares for a beneficial owner does not vote on a particular proposal because the nominee does not have discretionary voting power with respect to that item and/or has not received voting instructions from the beneficial owner. If a quorum is not present, the Annual Meeting will be adjourned or postponed until a quorum is present.

How many votes are needed to approve each item?

For the election of three (3) directors, each for a term of three (3) years:

| ● |  | You may vote in favor of or against each nominee or abstain from voting.

| ● |  | There is no cumulative voting for the election of directors.

| ● |  | For uncontested director elections, directors must be elected by a majority of the votes cast with respect to each director in the election of directors, which means that nominee(s) receiving more “for” votes than “against” votes cast will be elected.

| ● |  | Abstentions will have no effect on the outcome of the election.

| ● |  | The election of directors is a non-routine proposal, which means that brokers, banks or other nominees do not have discretion to vote any uninstructed shares. Broker non-votes represent votes not entitled to be cast on this matter and thus will have no effect on the result of the vote.

In voting to approve the Amended and Restated ICF International, Inc. 2018 Incentive Plan:

| ● |  | You may vote in favor of or against the proposal, or you may abstain from voting.

| ● |  | Approval of the additional shares for the Amended and Restated ICF International, Inc. 2018 Incentive Plan requires the affirmative vote of a majority of the shares entitled to vote thereon present electronically via live webcast or by proxy at the Annual Meeting.

| ● |  | Abstentions will have the same effect as voting against this proposal.

| ● |  | The approval of this proposal is a non-routine proposal, which means that brokers, banks or other nominees do not have discretion to vote any uninstructed shares. Broker non-votes represent votes not entitled to be cast on this matter and thus will have no effect on the result of the vote.

The Say on Pay vote is only an advisory vote to the Board regarding the overall pay-for-performance compensation program for the Company’s named executive officers (“NEOs”).

| ● |  | You may vote in favor of or against the Company’s compensation program, or you may abstain from voting.

| ● |  | The affirmative vote of the holders of at least 66 2/3% of the total number of outstanding shares of our common stock entitled to vote generally in the election of directors is required to approve the amendment.

| ● |  | Abstentions will have the same effect as voting against this proposal.

| ● |  | The approval of this proposal is a non-routine proposal which means that brokers, banks or other nominees do not have discretion to vote any uninstructed shares. Because approval of this action is based on the entire voting power of ICF, a broker non-vote will have the same effect as a vote AGAINST this proposal, even though brokers will not be able to vote any uninstructed shares.

In voting on the ratification of the selection of Grant Thornton as the independent registered public accounting firm:

| ● |  | You may vote in favor of the proposal, against the proposal, or abstain from voting.

| ● |  | The ratification of the selection of Grant Thornton as the independent registered public accounting firm is an advisory vote only that is performed as a means of good corporate governance, and as such, there are no minimum stockholder approval requirement; however, in order for ratification to occur, a majority of the votes entitled to be cast for this advisory vote must be received. While this is an advisory vote and it is not bound by it, the Board will seriously consider the outcome.

| ● |  | Abstentions will have the same effect as voting against the proposal.

| ● |  | Broker non-votes will have no effect on the voting, although no broker non-votes are expected to exist in connection with this vote as ratification of the independent registered public accounting firm is considered a routine matter under applicable rules.

To minimize the number of broker non-votes, the Company encourages you to provide voting instructions to the organization that holds your shares by carefully following the instructions provided in the Notice of Internet Availability of Proxy Materials or voting instruction form and by the organization that holds your shares.

How will voting on any other business be conducted?

We currently do not know of any business to be considered at the Annual Meeting other than the six (6) proposals described in this Proxy Statement. If any other business is properly presented at the Annual Meeting, your proxy gives authority to the named proxies to vote your shares on such matters, including any adjournment or postponement of the meeting, at their discretion.

Who will count the vote?

A representative of American Election Services, LLC will tabulate the votes and act as inspector of elections.

Where can I find the voting results of the Annual Meeting?

The preliminary voting results will be announced at the Annual Meeting. The final voting results will be tallied by the inspector of elections and published within four (4) business days following the conclusion of the Annual Meeting via a Form 8-K current event filing.

PROPOSAL 1

ELECTION OF DIRECTORS

Our authorized number of directors is presently fixed at eight (8), divided into three (3) classes, as noted below:

CLASS I |  | CLASS II |  | CLASS III
Dr. Srikant M. Datar |  | Ms. Marilyn Crouther |  | Ms. Cheryl W. Grisé
Mr. John M. Wasson |  | Mr. Michael J. Van Handel |  | Mr. Randall Mehl
|  | Dr. Michelle A. Williams |  | Mr. Scott Salmirs

Our directors are elected to serve three-year terms, so that the term of office of one (1) class of directors expires at each annual meeting.

The Board has nominated the following individuals for election as directors for a term expiring at our annual meeting of stockholders in 2026 or until their respective successors have been elected and qualified. All are currently Class II directors.

| Ø | Ms. Marilyn Crouther

| Ø | Mr. Michael J. Van Handel

| Ø | Dr. Michelle A. Williams

If any of these nominees becomes unavailable for election, the proxy may be used to vote for a substitute, or in favor of holding a vacancy to be filled by the directors. We have no reason to believe that any nominee will be unavailable. The uncontested director nominees will be elected by a majority of the votes cast at the Annual Meeting with respect to each director. For the Company’s purposes, “a majority of the votes cast” with respect to each director means that the number of votes for the director exceeds the number of votes against the director. You may vote for each nominee named.

Each of the nominees and each continuing director is a seasoned business leader who contributes an array of experience, qualifications, attributes, and skills to the Board. The following pages regarding each nominee and each continuing director provide background information and a summary of some of each person’s key qualifications to serve as a director. The nominees and continuing directors have extensive experience that lends itself to their inclusion on our Board, but we have only included their experience for the last five (5) years in their biography. Please also see the chart summarizing how each nominee and each continuing director reflects Board selection criteria adopted by our Governance and Nominating Committee of the Board (the “Governance and Nominating Committee”). The age indicated for each individual is as of December 31, 2022.

PROPOSAL 2

APPROVAL OF THE AMENDED AND RESTATED ICF INTERNATIONAL, INC.

2018 OMNIBUS INCENTIVE PLAN

The Board is requesting stockholder approval of the Amended and Restated ICF International, Inc. 2018 Omnibus Incentive Plan (the “Plan”), an amendment and restatement of the 2018 Incentive Plan. The Board adopted the 2018 Incentive Plan on April 4, 2018, and the 2018 Incentive Plan was first approved by our stockholders at the 2018 annual meeting of stockholders. The Board amended and restated the 2018 Incentive Plan (as set forth in the Plan), on April 5, 2023, upon the recommendation of the Board’s Human Capital Committee (for purposes of this proposal, the “Committee”) and subject to stockholder approval at the Annual Meeting.

Stockholders are being asked to approve the Plan in order to:

| ● |  | Increase the total number of shares authorized for issuance under the Plan by 450,000 shares to a total of 2,050,000 shares.

| ● |  | Incorporate provisions allowing for compensation recovery consistent with the requirements of Rule 10D-1 of the Securities Exchange Act of 1934, as amended, and exchange listing standards to be adopted thereunder by NASDAQ;

| ● |  | Rename the Plan as the “Amended and Restated ICF International, Inc. 2018 Omnibus Incentive Plan” and

| ● |  | Make certain other non-substantive and immaterial amendments intended to clarify various Plan provisions.

The full text of the Plan is reproduced as Exhibit A attached to this Proxy Statement.

Reasons for Amending and Restating the Plan

The Board believes that the opportunity to own Company common stock through the granting and vesting of restricted stock units, performance share awards and other stock awards under the Plan is critical to attracting, retaining and motivating the best executive, employee and non-employee director talent in a highly competitive talent environment, and to advancing the interests of the Company and its stockholders by providing equity-based incentives for effective service and high levels of performance by Plan participants (“Participants”). In the Board’s view, it is also appropriate to review and update its equity plan periodically to reflect changes in the law, to adopt emerging best practices and to streamline certain provisions of the equity plan based on the Company’s experience operating it.

At the Company’s 2018 and 2020 annual meeting of stockholders, our stockholders approved the issuance of an aggregate of 1,600,000 shares of the Company’s common stock in connection with equity grants under the 2018 Incentive Plan. If the amendment and restatement of the 2018 Incentive Plan contemplated by this Proposal is approved by our stockholders, the total number of shares available for issuance in connection with equity grants under the Plan will increase by 450,000 shares to a total of 2,050,000 shares. The Board anticipates that the 450,000 of additional shares being requested for inclusion in the Plan will be sufficient to provide projected equity incentives under the Plan for an additional two to three years, based on the Company’s current equity compensation practices as overseen by the Committee.

Additionally, on October 26, 2022, the SEC adopted Rule 10D-1 of the Exchange Act to implement the requirements of the Dodd-Frank Act. Rule 10D-1 directs the national securities exchanges and associations (including our own securities exchange, NASDAQ) to establish listing standards requiring each listed issuer to implement policies providing for, in the event of certain accounting restatements, the recovery of incentive-based compensation received by current or former executive officers to the extent such compensation was based on erroneously reported financial information. While Section 21.1 of the 2018 Incentive Plan includes compensation recoupment provisions which may be triggered by certain financial restatements or by certain actions taken by Participants that are detrimental to the Company’s business or reputation, these provisions apply to all Participants broadly and are not tailored to the requirements set forth in Rule 10D-1 or the proposed listing standards of NASDAQ. Accordingly, if Proposal 2 is approved by our stockholders, the Plan will incorporate a new Section 21.1(c) to ensure that awards granted under the Plan will also be subject to the requirements of any policy adopted by the Company to comply with Rule 10D-1 and the related NASDAQ listing standards to the extent that a Participant may be subject to compensation recovery under such a Company policy.

Lastly, the amendment and restatement renames the Plan as the “Amended and Restated ICF International, Inc. 2018 Omnibus Incentive Plan,” and incorporates other non-substantive and immaterial changes to clarify various Plan provisions.

Because only 670,133 shares remain available for issuance in connection with future grants under the 2018 Incentive Plan as of March 31, 2023, the Company may not have sufficient authorized shares to permit grants to executives, employees and directors in future years in accordance with current practices. As a result, if stockholders do not approve the Plan, we may be required to increase

|  | 16

##### Table of Contents

|  | PROPOSAL 2

the cash components of our compensation program, which could increase our expenses and hinder our ability to attract, motivate, and retain high-performing executives, employees, and non-employee directors and to align their interests with those of our shareholders. Additionally, the failure to approve this Proposal 2 may limit the Company’s ability to enforce any required recovery of incentive compensation under a policy adopted pursuant to Rule 10D-1 of the Exchange Act and the related NASDAQ listing standard. It is, therefore, the view of the Board that approval of the Plan, and each of the amendments to the 2018 Incentive Plan contained therein, is in the best interests of the Company and our stockholders.

Historical Burn Rate

The term “burn rate” describes how quickly a company is using the supply of shares authorized for issuance under its stock plan in connection with equity grants. Although long-term equity incentive grants are a key element of our executive compensation program, we are also mindful of our burn rate when granting equity awards and evaluating how many shares to request from stockholders for use with future grants, given the potential impact of those awards on our stockholders.

From 2020 to 2022, our three-year average burn rate was 1.21%.

Share Repurchase Program

In September 2017, our board approved a share repurchase program, which, as amended in November 2021, allows for an aggregate of $200.0 million of share repurchases from time to time at prevailing market prices. A principal purpose of the share buyback program is to mitigate the potential dilutive impact of employee stock-based compensation and to return wealth to stockholders. The share buybacks do not include shares repurchased from employees to satisfy their tax obligations from awards vesting.

Below is a review of our repurchase activity under the repurchase program for the last five (5) years. The chart does not report shares withheld from employees to satisfy their tax obligations upon the vesting of equity grants.

|  | Year |  | Number of Shares Repurchased |  |  | Dollar Value of Shares Repurchased |  |  | % of Total Common Shares Outstanding |  |  |
|  | 2022 |  |  | 176,375 |  |  | $ | 16,963,826.57 |  |  | 0.93% |  |  |  |
|  | 2021 |  |  | 197,800 |  |  | $ | 17,242,068.18 |  |  | 1.05% |  |  |  |
|  | 2020 |  |  | 278,582 |  |  | $ | 21,912,836.53 |  |  | 1.47% |  |  |  |
|  | 2019 |  |  | 248,000 |  |  | $ | 18,052,173.80 |  |  | 1.31% |  |  |  |
|  | 2018 |  |  | 214,137 |  |  | $ | 13,937,531.55 |  |  | 1.14% |  |  |  |

Dilution

The additional 450,000 shares that would be added to the Plan if it is approved by the stockholders represents approximately 2.4% of the Company’s approximately 18.8 million diluted shares outstanding as of March 31, 2023.

The Board believes that this is a reasonable and acceptable level of potential dilution given the strong incentive that equity grants can provide for employees to increase the value of the Company to the benefit of all stockholders.

Furthermore, we seek to mitigate the dilution from the stock issued under our equity plans with the share repurchase program we commenced in 2011 and have regularly renewed since then. From 2011 to March 31, 2023, we have repurchased 4,231,250 shares of common stock for an aggregate cost of approximately $211,416,091, pursuant to the program. The average fair value of the common stock purchased was $49.97 per share. Stock repurchases between 2011 to March 31, 2023, have exceeded the total stock issued under our equity plans by 779,489 shares. The timing of the share repurchases under the program is at the discretion of the Company and depends on a variety of factors, including market conditions and bank approvals and repurchases may be suspended or discontinued at any time.

Interests of Certain Persons

If this Proposal is adopted, each of our named executive officers and directors and certain other of our employees, will be eligible to receive a portion of their respective compensation for services in the form of restricted stock units (“RSUs”), performance share awards (“PSAs”), and other equity or equity-linked awards. The Board was aware of these interests and took them into account in recommending that the stockholders vote in favor of the proposal to approve the Plan.

Approval of the Plan requires the affirmative vote of a majority of the shares of the Company’s outstanding common stock present, electronically via live webcast or by proxy, and entitled to vote at the Annual Meeting. If approved by the stockholders, the Plan will become effective as of June 1, 2023.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE APPROVAL OF THE PLAN.

Summary of the Plan

Administration. The Plan is administered by the Committee. For more information concerning the Committee and its current members, please see page 34 of this Proxy Statement. The Committee has the authority to interpret the Plan, and to make any other determinations it believes necessary or advisable for the administration of the Plan. Subject to the terms of the Plan, the Committee may determine, among other items: the selection of those who may be granted awards under the Plan from among those eligible for participation; the level of participation of each Participant; when and how each award under the Plan shall be granted; and what type or combination of types of awards shall be granted. The Committee may delegate its authority under the 2018 Incentive Plan, as it determines appropriate, provided that delegation to officers or employees of the Company are subject to certain prudent limits set forth in the Plan and continued Committee oversight.

Plan Duration. The Plan will remain in effect, subject to the right of the Board of Directors to amend or terminate the Plan at any time, until all shares subject to it shall have been purchased or acquired according to the Plan’s provisions. In no event, however, may an award be granted under the Plan on or after ten (10) years from the date of the stockholder approval of the 2018 Incentive Plan.

Eligibility. All officers and all employees of the Company (including employees who are members of the Board and employees who are members of senior management of entities acquired by the Company) and its affiliates, as well as the Company’s non-employee directors, are eligible to participate in the Plan. From time to time, the Committee will determine who will be granted awards and the number of shares granted, and all such awards are at the sole discretion of the Committee. The Committee considers factors such as performance (currently and over time), long-term potential, contributions to the Company’s success, effort level, and desire to retain the employee, as well as other relevant factors determined on a case-by-case basis in determining who will receive grants from time to time under the Plan.

As of December 31, 2022, the Company had 1,592 officers and employees who are eligible to participate in the Plan.

Shares and Amounts Available for Awards. The aggregate number of shares of common stock that may be issued under all stock-based awards made under the Plan will be 2,050,000. Upon approval of the Plan, at this Annual Meeting, there will be a total of 1,120,133 shares remaining available for future awards (comprised of 670,133 shares remaining available under the 2018 Incentive Plan as of March 31, 2023, and an additional 450,000 shares that will become available upon approval of the Plan by our stockholders). Shares that are related to awards under the Plan that are forfeited, cancelled or expire unexercised, or related to awards that are settled in cash shall be added back and shall be available again for issuance under the Plan.

Non-Employee Director Awards. Equity awards to non-employee directors may not exceed $400,000 in any year.

Stock Awards. The Plan provides for grants of restricted stock, RSUs, PSAs, performance units, and other stock-based awards. Performance goals may be based on the achievement of specified levels of Company performance (or performance of an applicable subsidiary, affiliate or unit of the Company, or any combination thereof) under one (1) or more of the performance measures set forth in the Plan. Performance goals may be defined in absolute terms or measured relative to the performance of companies or against a predefined index that the Committee deems appropriate, or, if utilizing the performance measure of share price, a comparison to various stock market indices. Performance goals may be adjusted for material business events. The performance goals will be set by the Committee and may include:

| ● |  | Net earnings or net income (before or after taxes);

| ● |  | Earnings per share;

| ● |  | Gross or net sales or revenue growth;

| ● |  | Product invoice;

| ● |  | Net operating profit;

| ● |  | Return measures (including, but not limited to, return on assets, capital, invested capital, equity, sales or revenue);

| ● |  | Cash flow (including but not limited to operating cash flow, free cash flow, cash flow return on equity, and cash flow return on investment);

| ● |  | Earnings before or after taxes, interest, depreciation, and/or amortization;

| ● |  | Gross or operating margins;

| ● |  | Productivity ratios;

| ● |  | Share price (including, but not limited to, growth measures and total stockholder return);

| ● |  | Expense targets;

| ● |  | Cost reduction or savings;

| ● |  | Performance against operating budget goals;

| ● |  | Margins;

| ● |  | Operating efficiency;

| ● |  | Funds from operations;

| ● |  | Market share;

| ● |  | Customer satisfaction;

| ● |  | Working Capital targets

| ● |  | Gross revenue;

| ● |  | Revenue after subcontractor costs;

| ● |  | Service sales;

| ● |  | Contract backlog;

| ● |  | Business pipeline;

| ● |  | Economic value added or EVA (net operating profit after tax minus the product of capital multiplied by the cost of capital);

| ● |  | Debt levels;

| ● |  | Days Sales Outstanding; and

| ● |  | Contract Awards/Book-to-Bill.

Stock Options. Stock options granted under the Plan may be either incentive stock options (“ISOs”) or nonqualified stock options qualifying under Section 422 of the Internal Revenue Code (“NQSOs”). Under the Internal Revenue Code (the “Code”), the aggregate fair market value (determined at the grant date) of the stock with respect to which ISOs are first exercisable by any individual during any calendar year shall not exceed $100,000. Stock options in excess of this limit are treated as NQSOs. The stock option price may not be less than the fair market value of the stock on the date the stock option is granted. The stock option price is payable in cash or, if the grant provides, in common stock or other equity instruments. The Committee determines the expiration date of stock options at grant, provided that no stock option may be exercisable later than the tenth anniversary of the grant date.

|  | PROPOSAL 2

Stock Appreciation Rights (“SARs”). SARs may, but need not, be granted in conjunction with options or other equity awards. The Committee determines the terms of each SAR at the time of the grant. Any freestanding SAR (that is, a SAR not granted in conjunction with another equity award) may not be granted at less than the fair market value of the stock on the date the SAR is granted and cannot have a term longer than ten (10) years. Distributions to the recipient may be made in common stock, in cash, or in a combination of both as determined by the Committee at the time of grant.

Cash-Based and Other Stock-Based Awards. Cash-based and other stock-based awards granted under the Plan entitle each participant to receive a specified payment amount or payment range, in the form of cash or shares of common stock or other equity awards, as determined at the time of the award, upon the attainment of specified performance goals during a performance period, which may be one (1) or more years, as determined by the Committee at the time of the award.

Amendment and Revocation. The Board may terminate the Plan or an outstanding award agreement at any time, and the Committee may amend the Plan or an outstanding award agreement at any time. However, an amendment will be contingent upon stockholder approval to the extent required by law or the rules of any stock exchange on which the Company’s stock is traded. The Plan prohibits the terms of outstanding awards from being amended to reduce the exercise price of outstanding options or SARs and prohibits, without stockholder approval, the cancellation of outstanding options or SARs in exchange for cash, other awards, or new options or SARs with an exercise price that is less than the exercise price of the original options or SARs.

Certain Adjustments. In the event of a corporate event or transaction, the Committee, in its sole discretion and in order to prevent unintended dilution or enlargement of a participant’s rights under the Plan, shall substitute or adjust, subject to the Committee’s sole discretion in determining the methodology and manner of such substitution or adjustment, among other things:

| • |  | the number and kind of shares that may be issued under the Plan or under particular forms of awards;

| • |  | the number and kind of shares subject to outstanding awards;

| • |  | the option or grant price applicable to outstanding awards; and

| • |  | any other value determinations applicable to outstanding awards.

A corporate event or transaction (including, but not limited to, a change in the shares or capitalization of the Company) encompasses a merger, consolidation, reorganization, recapitalization, separation, partial or complete liquidation, stock dividend, stock split, reverse stock split, split up, spin-off, or other distribution of stock or property of the Company, combination of shares, exchange of shares, dividend in-kind, or other like change in capital structure or distribution (other than normal cash dividends) to stockholders of the Company, or any similar corporate event or transaction.

Transferability. Unless otherwise determined by the Committee, awards granted under the Plan may not be transferred except by will or the laws of descent and distribution or, subject to the consent of the Committee, pursuant to a domestic relations order entered into by a court of competent jurisdiction. During an employee’s lifetime, any options or awards may be exercised only by the employee. Notwithstanding the above, no award may be transferred for value without stockholder approval.

Other Provisions. Except for 5% of the shares available for equity awards, there is a one (1) year minimum vesting/restriction/performance period requirement for equity awards. In addition, upon a change of control of the Company, equity awards will not have accelerated vesting unless the employee or non-employee director has a termination of employment or board service, without cause, within twenty-four (24) months following the change of control of the Company.

U.S. Tax Treatment of Options and Awards

The following is a general description of the material United States federal income tax treatment of awards under the Plan. It is based on United States tax laws and regulations existing on the date of this Proxy Statement, and there can be no assurance that such laws and regulations will not change. This description is not exhaustive, not intended to constitute tax advice to anyone, and does not describe state, local or foreign tax consequences.

Incentive Stock Options. An ISO results in no taxable income to the optionee or deduction to the Company at the time it is granted or exercised. However, the excess of the fair market value of the shares acquired over the option price is an item of adjustment in computing the alternative minimum taxable income of the optionee. If the optionee holds the stock received as a result of an exercise of an ISO for at least two (2) years from the date of the grant and one (1) year from the date of exercise, then the gain realized on disposition of the stock is treated as a long-term capital gain. If the shares are disposed of prior to the end of this period, however (i.e., a “disqualifying disposition”), then the optionee will include in income, as compensation for the year of the disposition, an amount equal to

|  | 20

##### Table of Contents

|  | PROPOSAL 2

the excess, if any, of the fair market value of the shares upon exercise of the option over the option price (or, if less, the excess of the amount realized upon disposition over the option price). In that event, the excess, if any, of the sale price over the fair market value on the date of exercise will be a short-term capital gain. In addition, the Company will be entitled to a deduction, in the year of such a disposition, for the amount includible in the optionee’s income as compensation. The optionee’s basis in the shares acquired upon exercise of an ISO is equal to the option price paid, plus any amount includible in his or her income as a result of a disqualifying disposition.

Nonqualified Stock Options. An NQSO results in no taxable income to the optionee or deduction to the Company at the time it is granted. An optionee exercising such an option will, at that time, realize compensation income taxable at ordinary income tax rates in the amount of the difference between the then market value of the shares and the option price. Subject to the applicable provisions of the Code, a deduction for federal income tax purposes will be allowable to the Company in the year of exercise in an amount equal to the taxable compensation realized by the optionee.

The optionee’s basis in such shares is equal to the sum of the option price plus the amount includible in his or her income as compensation upon exercise. Any gain (or loss) upon subsequent disposition of the shares will be a long-term or short-term gain (or loss), depending upon the holding period of the shares.

If an NQSO is exercised by tendering previously owned shares of the Company’s common stock in payment of the option price, then, instead of the treatment described above, the following will apply: a number of new shares equal to the number of previously owned shares tendered will be considered to have been received in a tax-free exchange; the optionee’s basis and holding period for such number of new shares will be equal to the basis and holding period of the previously owned shares exchanged. The optionee will have compensation income taxable at ordinary income tax rates equal to the fair market value on the date of exercise of the number of new shares received in excess of such number of exchanged shares; the optionee’s basis in such excess shares will be equal to the amount of such compensation income; and the holding period in such shares will begin on the date of exercise.

Stock Appreciation Rights. Generally, the recipient of an SAR will not recognize taxable income at the time the SAR is granted. Upon the exercise of an SAR, if an employee receives the appreciation inherent in the SAR in cash, the cash will be taxed as compensation income to the employee at the time it is received. If an employee receives the appreciation inherent in the SAR in stock, the fair market value of the stock will be taxed as compensation income to the employee at the time such stock is received.

In general, there will be no federal income tax deduction allowed to the Company upon the grant or termination of SARs. However, upon the exercise of an SAR, the Company will be entitled to a deduction equal to the amount of ordinary income the recipient is required to recognize as a result of the exercise.

Restricted Stock/RSU Awards/Performance Awards. No income will be recognized at the time of grant by the recipient of a restricted stock, or PSA if such award is subject to a substantial risk of forfeiture. Generally, at the time the substantial risk of forfeiture terminates with respect to a restricted stock award or PSA, the then fair market value of the stock will constitute ordinary income to the employee. No income will be recognized at the time of grant by the recipient of an RSU or performance unit award; however, ordinary income will be recognized upon the receipt of payment of the vested RSU or performance unit award equal to the amount of cash or the fair market value of the Company’s common stock so received. Subject to the applicable provisions of the Code, a deduction for federal income tax purposes will be allowable to the Company in an amount equal to the compensation realized by the employee. However, a recipient of restricted stock may, within thirty (30) days of grant, elect to recognize income equal to the fair market value of the restricted stock on the date of grant and there is no further income recognition when the restrictions lapse (but no refund or tax deductions if the restricted stock is forfeited).

Tax Treatment of Awards to Non-Employee Directors and to Employees Outside of the United States

The grant and exercise of options and awards under the Plan to non-employee directors and to employees outside of the United States may be taxed on a different basis.

PROPOSAL 3

ADVISORY SAY ON PAY VOTE REGARDING ICF’S

OVERALL PAY-FOR-PERFORMANCE NAMED EXECUTIVE OFFICER COMPENSATION PROGRAM

In April of 2017, the Board approved a resolution providing that the Company would hold an annual stockholder advisory vote on executive compensation, as advised by the Company’s stockholders at the 2017 annual meeting of stockholders. Pursuant to that resolution and as required pursuant to Regulation 14A of the Exchange Act, this proposal, commonly known as a “Say on Pay” proposal gives you, as a stockholder, the opportunity to endorse or not endorse the Company’s NEO compensation program through the following resolution:

“Resolved, that the stockholders approve ICF International’s overall pay-for-performance executive compensation program for its named executive officers, as described in the Compensation Discussion and Analysis, the compensation tables and the related narratives and other materials in the Proxy Statement.”

Approval of the Say on Pay proposal requires the affirmative vote of a majority of the votes entitled to vote thereon present electronically via live webcast or by proxy at the Annual Meeting.

The Human Capital Committee and the full Board believe that the Company’s executive compensation program, as described in the Compensation Discussion and Analysis (“CD&A”) and other sections noted in the resolution set forth above, reflects a pay-for-performance culture at the Company that is rooted in our values. The Human Capital Committee and the Board believe that the executive compensation program is rational and effective in that it aligns the interests of the NEOs with both the short-term and long-term interests of stockholders, while reducing incentives for unnecessary and excessive risk taking.

In making a decision on the Say on Pay proposal the Board asks that stockholders consider the following:

| ○ | ICF’s NEO compensation is competitive and in line with its market peers.

| ○ | ICF’s executive compensation program is incentive-based and reflects a pay-for-performance culture.

| ○ | ICF’s executive compensation program relies heavily on stock-based awards vesting over a period of time.

| ○ | Performance Share Awards vest over three (3) years, contingent on achievement of certain performance thresholds.

| ○ | Restricted Stock Units vest over a period of three (3) years with 25% vesting on each of the first anniversary and second anniversary, and 50% vesting on the third anniversary.

| ○ | Our performance-equity program (the “Performance Program”) further emphasizes ICF’s commitment to a pay-for-performance culture that links compensation to positive results.

| ○ | ICF offers no material perquisites.

| ○ | The severance arrangements with Messrs. Morgan, Broadus, and Lee and Ms. Choate include strong “clawback” rights.

| ○ | ICF has a strong corporate governance culture.

At the Company’s 2022 annual meeting of stockholders, approximately 97% of the votes cast on the Say on Pay proposal were voted in favor of our overall pay-for-performance NEO compensation program. The Human Capital Committee and the Board believe this affirms the stockholders’ strong support of the Company’s approach to NEO compensation.

In accordance with applicable law, this vote is “advisory,” meaning it will serve as a recommendation to the Board but will not be binding. The Human Capital Committee will seriously consider the outcome of this vote when determining future compensation arrangements for named executive officers.

It is expected that the next Say on Pay vote will occur at the 2024 annual meeting of stockholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE ADVISORY SAY ON PAY VOTE REGARDING ICF’S OVERALL PAY-FOR-PERFORMANCE NAMED EXECUTIVE OFFICER COMPENSATION PROGRAM.

PROPOSAL 4

ADVISORY VOTE ON FREQUENCY OF HOLDING FUTURE SAY ON PAY VOTES ON NAMED EXECUTIVE OFFICER COMPENSATION

As described in Proposal 3 above, you have the opportunity to cast an advisory vote on ICF’s named executive compensation program. Under Regulation 14A of the Exchange Act, ICF International’s stockholders are required to vote, on an advisory (non-binding) basis, on the frequency with which they would prefer to cast an advisory (non-binding) Say on Pay vote on named executive compensation at future annual meetings (or any special stockholder meeting for which ICF must include executive compensation information in the proxy statement for that meeting). This stockholder vote, commonly referred to as the “Say on Frequency” vote, must occur at least every six (6) years. By voting on this proposal, stockholders may indicate whether they prefer that we seek an advisory Say on Pay vote every year, every two years or every three years. You may also choose to abstain from voting.

After careful consideration of the frequency alternatives, the Board believes that continuing to conduct an annual advisory (non-binding) Say on Pay vote is appropriate for ICF and its stockholders at this time because such timing for the advisory vote will ensure our stockholders are engaged in compensation decisions for named executive officers. Although ICF’s named executive officer compensation programs are designed to promote a long-term connection between pay and performance, awards to ICF’s NEOs are typically made annually, and improvements to executive compensation plans are often considered and adopted on an annual basis. As such, the Board believes that holding an annual advisory (non-binding) Say on Pay vote on executive compensation is appropriate for timely feedback on ICF’s compensation disclosures and is consistent with best practices. ICF will continue to monitor developments in executive compensation practices and the appropriateness and effectiveness of an annual Say on Pay vote on named executive officer compensation, and ICF may change its recommendation on the desired frequency in the future.

The Board also believes that an annual Say on Pay vote is consistent with ICF’s practice of seeking input and engaging in dialogue with its stockholders on corporate governance matters (including annually providing stockholders the opportunity to ratify the Company’s selection of an independent registered public accounting firm) and the Company’s named executive officer compensation philosophy, policies and practices.

Consistent with our stockholders’ preference expressed at the 2017 annual meeting of stockholders and the considerations discussed above, the Board determined that the Say on Pay vote on named executive officer compensation should continue to be conducted annually.

While we intend to carefully consider the results of this proposal, the Say on Frequency vote is advisory in nature and therefore not binding on us, our Board or our Human Capital Committee. Our Board and Human Capital Committee value the opinions of all of our stockholders and will consider the outcome of this Say on Frequency vote when deciding upon the frequency of the stockholder vote on named executive officer compensation. However, the Board may decide that it is in the best interests of ICF and its stockholders to hold an advisory Say on Pay vote on named executive officer compensation on a different frequency than the option approved by ICF’s stockholders.

The Board will seriously consider the outcome of this vote when determining how often to hold a Say on Pay vote.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE FOR THE FUTURE ADVISORY SAY ON PAY VOTE ON NAMED EXECUTIVE OFFICER COMPENSATION TO OCCUR EVERY YEAR (AS OPPOSED TO EVERY TWO YEARS OR EVERY THREE YEARS) UNDER PROPOSAL 4.

PROPOSAL 5

AMENDMENT OF ICF INTERNATIONAL’S AMENDED AND RESTATED ARTICLES OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OFFICERS OF ICF

At the Annual Meeting, the stockholders will be asked to approve an amendment (the “Amendment”) to the Certificate of Incorporation of the Company (the “Charter”) to provide exculpation from liability for officers of the Company from certain claims of breach of the fiduciary duty of care, similar to protections currently available to directors of the Company.

The proposal would amend Article Fifth of the Charter to read in its entirety as follows:

FIFTH: Elimination of Certain Liability of Directors. No director or officer of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, as applicable, except (a) for any breach of the director’s or officer’s duty of loyalty to the Corporation or its stockholders, (b) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (c) for any transaction from which the director or officer derived an improper personal benefit or (d) as applicable solely to directors, for any payment of a dividend or approval of a stock repurchase that is illegal under Section 174 of the DGCL, or to the extent such exemption from liability or limitation thereof is not permitted under the DGCL as the same exists or may hereafter be amended. If the DGCL is hereafter amended to permit a corporation to further eliminate or limit the liability of a director or officer of a corporation, then the liability of a director or officer of the Corporation, in addition to the circumstances in which a director or officer is not personally liable as set forth in the preceding sentence, shall, without further action of the directors or stockholders, be further eliminated or limited to the fullest extent permitted by the DGCL as so amended. Neither any amendment (including any amendment effected by operation of law, by merger, consolidation or otherwise), repeal, or modification of this Article FIFTH, nor the adoption or amendment of any other provision of this Certificate of Incorporation or the bylaws of the Corporation inconsistent with this Article FIFTH, shall adversely affect any right or protection provided hereby with respect to any act or omission occurring prior to the date when such amendment, repeal, modification, or adoption became effective.

Background

The Company is incorporated in the State of Delaware and therefore subject to the Delaware General Corporation Law (“DGCL”). The DGCL permits Delaware corporations to limit or eliminate directors’ personal liability for monetary damages resulting from a breach of the fiduciary duty of care, subject to certain limitations such as prohibiting exculpation for intentional misconduct or knowing violations of the law. These provisions are referred to as “exculpatory provisions” or “exculpatory protections.” These exculpatory provisions for directors are currently included in the Company’s Certificate of Incorporation.

Recently, the Delaware legislature amended the DGCL to permit Delaware corporations to provide similar exculpatory protections for officers of corporations. This decision was due in part to the recognition that both officers and directors owe fiduciary duties to corporations, and yet only directors were protected by the exculpatory provisions. In addition, Delaware courts experienced an increase in litigation in which plaintiffs attempted to exploit the absence of protection for officers to prolong litigation and extract settlements from defendant corporations. As adopted, amended Section 102(b)(7) protects officers under limited circumstances as explained below.

Conditions and Limitations to Exculpation under Section 102(b)(7)

As amended, Section 102(b)(7) of the DGCL provides important conditions and limitations on a corporation’s exculpation of its officers for monetary damages from breaches of fiduciary duty.

| ● |  | Exculpation is only available for breaches of the fiduciary duty of care.

| ● |  | Exculpation is not available for breaches of the fiduciary duty of loyalty (which requires officers to act in good faith for the benefit of the corporation and its stockholders and not for personal gain).

| ● |  | Exculpation is not available for intentional misconduct or knowing violations of the law.

| ● |  | The protections of Section 102(b)(7) are limited to monetary damages only; claims against officers for equitable relief remain available.

| ● |  | Exculpation is not available in connection with derivative claims on behalf of the corporation by a stockholder.

|  | 25

##### Table of Contents

|  | PROPOSAL 5

Reasons for the Proposal

The Board believes that eliminating personal monetary liability for officers under certain circumstances is reasonable and appropriate. Claims against corporations for breaches of fiduciary duties are expected to continue increasing. Delaware corporations that fail to adopt officer exculpation provisions may experience a disproportionate amount of nuisance litigation and disproportionately increased costs in the form of increased director and officer liability insurance premiums, as well as diversion of management attention from the business of the corporation.

Further, the Board anticipates that similar exculpation provisions are likely to be adopted by the Company’s peers and others with whom the Company competes for executive talent. As a result, officer exculpation provisions may become necessary for Delaware corporations to attract and retain experienced and qualified corporate officers.

A Delaware corporation seeking to extend the benefits of the newly amended Section 102(b)(7) to its corporate officers must amend its certificate of incorporation, as the protections do not apply automatically and must be embedded in the corporation’s certificate of incorporation to be effective. Accordingly, the Board has determined it advisable and in the best interests of the Company and its stockholders to seek approval for the Amendment.

Effect of the Proposal if Approved

The Amendment would provide for the elimination of personal monetary liability for certain officers only in connection with direct claims brought by stockholders, subject to the limitations described under the heading “Conditions to Exculpation Under Section 102(b)(7)”. As is the case with directors under the Charter, the Amendment would not limit the liability of officers for any breach of the duty of loyalty to the Company or its stockholders, any acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of the law, and any transaction from which the officer derived an improper personal benefit.

If the Amendment is approved by the stockholders at the Annual Meeting, it will become effective upon the filing of the Amendment with the Secretary of State of the State of Delaware; however in accordance with the DGCL, the Board may abandon the Amendment without further action by the stockholders at any time prior to the effectiveness of the filing of the Amendment with the Secretary of State of the State of Delaware, notwithstanding stockholder approval.

Board Approval and Vote Required

On April 5, 2023, the Board authorized and approved the Amendment, subject to stockholder approval, and directed that the Amendment be considered for approval by the stockholders at the Annual Meeting. In accordance with Article 7.6 of the Charter, the Amendment must be approved by the affirmative vote of the holders of at least 66 2/3% of the voting power of the outstanding shares of Company capital stock entitled to vote generally in the election of directors.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE AMENDMENT TO THE ICF INTERNATIONAL AMENDED AND RESTATED ARTICLES OF INCORPORATION TO LIMIT THE LIABILITY OF CERTAIN OFFICERS OF ICF.

PROPOSAL 6

RATIFICATION OF THE SELECTION OF THE INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board (the “Audit Committee”) has appointed Grant Thornton to serve as our independent registered public accounting firm (“independent auditor”) for fiscal year 2023 and requests that stockholders ratify such appointment. For a discussion of factors considered by the Audit Committee in connection with the appointment of Grant Thornton, see “Audit Committee Report – Auditor Selection”.

Grant Thornton audited our consolidated financial statements for 2022 and 2021. Representatives of Grant Thornton are expected to be present at the Annual Meeting, will have an opportunity to make a statement if they so desire, and will be available to respond to appropriate questions from stockholders. Ratification of the appointment of Grant Thornton as our independent auditor requires a majority of the votes entitled to vote thereon present electronically via live webcast or by proxy at the Annual Meeting. If our stockholders do not ratify Grant Thornton as our independent auditor, the Audit Committee will reconsider its decision. Even if stockholders vote in favor of the appointment, the Audit Committee may, in its discretion, and without re-submitting the matter to the Company’s stockholders, direct the appointment of a different independent auditor at any time during the year if it determines that such a change would be in the best interests of the Company and stockholders.

THE BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE FOR THE RATIFICATION OF THE SELECTION OF GRANT THORNTON LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR 2023.

|  | PROPOSAL 6

Pre-Approval of Audit and Non-Audit Services

The Audit Committee is authorized by its charter to pre-approve all audit and permitted non-audit services to be performed by our independent auditor. The Audit Committee reviews and approves the independent auditor’s retention to perform audit services, including the associated fees. The Audit Committee also evaluates other known potential engagements of the independent auditor, including the scope of the proposed work and the proposed fees, and approves or rejects each service, taking into account whether the services are permissible under applicable law and the possible impact of each non-audit service on the independent auditor’s independence from management. At subsequent meetings, the Audit Committee will receive updates on the services actually provided by the independent auditor, and management may present additional services for approval. The Audit Committee has delegated to the Chair of the Audit Committee the authority to evaluate and approve engagements on behalf of the Audit Committee in the event that a need arises for pre-approval between Audit Committee meetings. If the Chair so approves any such engagement, he or she will report that approval to the full Audit Committee at its next meeting.

Approval of Fees

Our Audit Committee has reviewed all of the fees described above. In connection with the Audit Committee’s review and approval of the amount of fees paid to the independent auditor for audit, audit-related and other services, the Audit Committee considers, among other factors:

| ● |  | The independent auditor’s qualifications and quality control procedures;

| ● |  | The quality of the independent auditor’s overall performance;

| ● |  | The complexity of the audit and related services in a particular year;

| ● |  | Publicly available information concerning audit fees paid by peer companies; and

| ● |  | The impact, if any, of the level of audit and non-audit fees on the auditor’s independence.

The Audit Committee believes that such fees are compatible with maintaining the independence of Grant Thornton.

|  | AUDIT COMMITTEE REPORT

AUDIT COMMITTEE REPORT

The Audit Committee is appointed by the Board, and each of the members of the Audit Committee has been determined by the Board to be “independent” under the applicable NASDAQ standards. The Board has also determined that all of the members of the Audit Committee are “financially literate” under the NASDAQ rules. The Audit Committee’s Chair, Ms. Marilyn Crouther, and Committee members Mr. Michael Van Handel and Dr. Srikant Datar each qualify and are designated as “audit committee financial experts”, as defined by the SEC.

Audit Committee Duties

Under the Audit Committee’s Charter, the committee’s duties and responsibilities include, among others:

| ● |  | Overseeing of the relationship with the independent auditor, including being directly responsible for the appointment and compensation of the Company’s independent auditor;

| ● |  | Assessing the qualifications, performance and independence of the Company’s independent auditor;

| ● |  | Reviewing the activities, qualifications and performance of the Company’s internal audit function;

| ● |  | Monitoring financial reporting and disclosure and related matters;

| ● |  | Reviewing and evaluating the Company’s overall risk profile, the procedures and policies adopted to identify and manage such risks and related disclosures;

| ● |  | Retaining independent external advisors as the Audit Committee determines necessary or appropriate;

| ● |  | Annually reviewing the adequacy of the Audit Committee’s charter and the Audit Committee’s own performance; and

| ● |  | Preparing this report to the Company’s stockholders.

The Audit Committee also periodically reviews the Company’s Code of Business Ethics and Conduct (the “Code of Ethics”) and receives reports from the Company’s Compliance Committee, a management committee which is charged with the implementation of the Code Ethics. In connection with these responsibilities, the Audit Committee oversees the Company’s procedures for the receipt, retention and treatment, on a confidential basis, of any complaints received by the Company’s Compliance Committee. The Company encourages employees and third-party individuals and organizations to report concerns about our accounting, internal accounting controls, auditing matters or other matters that may or appear to involve financial or any other wrongdoing.

Audit Committee Oversight Role

In performing its functions, the Audit Committee acts in an oversight capacity. In that role, the Audit Committee relies on the

work and assurances of: the Company’s management, which has the primary responsibility for financial statements and reports, internal controls and financial reporting processes; the internal audit function; and the independent auditor that, in its reports, expresses opinions on the conformity of the Company’s financial statements to United States Generally Accepted Accounting Principles and on the effectiveness of the Company’s internal control over financial reporting.

Audit Committee Activities

During the year, the Audit Committee meets with management and representatives of the independent auditor and the internal audit function to review and discuss the Company’s quarterly financial statements before the Company’s results are released to the public. Members of the Committee also review the Company’s quarterly reports on Form 10-Q and the annual report on Form 10-K. In the course of these activities, the Audit Committee:

| ● |  | Reviews the scope of overall plans for and status of the annual audit and internal audit program;

| ● |  | Consults with management, the internal audit function and the independent auditor on topics such as the Company’s processes for risk assessment and risk management and related disclosures;

| ● |  | Reviews and approves the Company’s policy for preapproval of audit and permitted non-audit services by the independent auditor;

| ● |  | Reviews with management and the independent auditor the internal audit function and the scope and effectiveness of the Company’s disclosure controls and procedures, including for purposes of evaluating the accuracy and fair presentation of the Company’s financial statements in connection with the certifications made by the Company’s Chief Executive Officer and Chief Financial Officer;

| ● |  | Receives advice on critical accounting policies and the impact of new accounting principles and guidance; and

| ● |  | Reviews significant legal and other developments in the Company’s processes for monitoring compliance with law and Company policies and oversees the activities of the Company’s Chief Ethics and Compliance Officer and management’s Compliance Committee.

The Audit Committee meets regularly, and not less than annually, with the independent auditor, in each case with and without members of management present, to discuss the results of the auditor’s examinations and evaluations of the Company’s internal controls and the overall quality and integrity of the Company’s financial reporting.

Review of Fiscal 2022 Financial Statements

The Audit Committee reviewed and discussed with our management and with our independent auditor, Grant Thornton, the consolidated financial statements of ICF and its subsidiaries and related notes, the disclosures under the headings “Management’s Discussion and Analysis” and “Management’s Report on Internal Controls”, and other financial disclosures as set forth in our 2022 Form 10-K. In connection with this review, the Audit Committee:

| ● |  | Discussed with Grant Thornton those matters required to be discussed by Auditing Standard No. 1301 (Communications with Audit Committees), issued by the Public Company Accounting Oversight Board (“PCAOB”), and Rule 2-07 (Communication with Audit Committees) of SEC Regulation S-X; and

| ● |  | Received from Grant Thornton the written communications required by Ethics and Independence Standard No. 3526 (Communication with Audit Committees Concerning Independence), issued by the PCAOB, as to Grant Thornton’s compliance with all rules, standards, and policies of the PCAOB and SEC governing auditor independence.

Based on the activities, reviews and discussions outlined above, the Audit Committee recommended to the Board that the audited consolidated financial statements for the fiscal year ended December 31, 2022 be included in our 2022 Form 10-K.

Auditor Selection

As described under the heading, “Proposal 6: Ratification of the Selection of the Independent Registered Public Accounting Firm”, the Audit Committee also approved the selection of Grant Thornton as the Company’s independent auditor for the fiscal year ending December 31, 2023, as being in the best interest of the Company. Grant Thornton has served as the Company’s independent auditor since the Company went public in 2006.

In connection with the appointment of the independent auditor, the Audit Committee discusses and considers factors such as the following:

| ● |  | The independent auditor’s historical and recent performance on the audit, taking into account the views of management and the internal audit function;

| ● |  | External data relating to audit quality and performance, including recent PCAOB reports on the independent auditor and its peer firms;

| ● |  | The familiarity of the independent auditor, and the team assigned to the Company’s audit and related work, with the government services industry;

| ● |  | The independent auditor’s tenure as the Company’s independent auditor and its familiarity with the Company’s accounting policies and practices and internal control over financial reporting;

| ● |  | The independent auditor’s capacity, capability and expertise in handling the breadth and complexity of the Company’s global operations;

| ● |  | The independent auditor’s independence and objectivity and the quality and candor of communications within management and the Audit Committee; and

| ● |  | The appropriateness of the independent auditor’s fees for audit and non-audit services.

For a discussion of factors considered by the Audit Committee in reviewing the amount of fees paid to Grant Thornton for audit and other services, see “Proposal 6: Ratification of the Selection of the Independent Registered Public Accounting Firm – Approval of Fees”.

The Audit Committee also reviews and considers the performance of the lead audit partner. Under applicable law, the lead audit partner must rotate after five (5) years. The Company’s current lead audit partner is serving in that capacity for his first year. The process for selection of the Company’s lead audit partner pursuant to this rotation policy involved meetings between the Chair of the Audit Committee and the candidate for the role, as well as discussions and meetings with the Audit Committee and management.

CORPORATE GOVERNANCE AND BOARD MATTERS

Board and Committee Meetings in 2022

The table below shows the number of Board and committee meetings held in 2022. Our Board has eight (8) regularly scheduled meetings per year and special meetings are called as the need arises. These meetings are usually held at our corporate headquarters, which was in Fairfax, Virginia until October 2022, when it moved to Reston, Virginia. Due to COVID-19 restrictions, meetings held in the first half of 2022 were conducted via video/teleconference with most meetings in the second half of the year being held in person.

Number of Meetings Held |
Board of Directors |  |  | 10 |
Audit Committee |  |  | 8 |
Human Capital Committee |  |  | 6 |
Governance and Nominating Committee |  |  | 4 |

Directors are expected to attend Board meetings, our annual meeting of stockholders, and the meetings of the committees on which they serve. During 2022, each director attended at least 75% of the total meetings of the Board and those committees on which he or she served. Each director attended our annual meeting of stockholders held in 2022, other than Mr. Peter Schulte, whose term ended at the annual meeting.

Corporate Governance Guidelines

Our Board has established a set of Corporate Governance Guidelines that addresses such matters as, among other things, the roles of the Board and management (including the role of the Lead Independent Director), Board and director responsibilities, Board composition, selection of directors, operations of the Board (including meetings), and functions of the Board committees. The Board believes such guidelines, which are reviewed at least annually, are appropriate for the Company in its effort to maintain “best practices” as to corporate governance.

Director Independence

The Board has affirmatively determined that Ms. Cheryl Grisé, Ms. Marilyn Crouther, Dr. Michelle Williams, Dr. Srikant Datar, and Messrs. Randall Mehl, Scott Salmirs and Michael Van Handel are independent directors in accordance with the requirements of NASDAQ and the rules of the SEC. Mr. Peter Schulte, who was a director until his term ended at the 2022 annual meeting and chose to not stand for re-election, was also independent in accordance with the requirements of NASDAQ and the rules of the SEC through the end of his term. We believe we comply with all applicable requirements of the SEC and NASDAQ relating to director independence and the composition of the committees of our Board.

Board Leadership Structure; Lead Independent Director

Mr. John Wasson, the Company’s President and Chief Executive Officer assumed the position of Chair of the Board effective upon Mr. Sudhakar Kesavan’s retirement. Consistent with its past practice when Mr. Kesavan served as both Chairman of the Board and CEO, the Board believes combining the CEO and Chair positions is appropriate and in the best interests of the Company and its stockholders because it provides the following advantages:

| ● |  | The CEO is the director most familiar with the Company’s business and industry and is best situated to lead Board discussions on important matters affecting ICF International; and

| ● |  | Having the CEO serve in such roles creates a firm link between management and the Board and promotes the development and implementation of corporate strategy.

The Board continues to believe that when an executive serves as the Chair, it is in the best interests of the Company and its stockholders to designate a Lead Independent Director who is an independent director and, among other duties:

| ● |  | Chairs any meeting of the independent directors in executive session;

| ● |  | Facilitates communications between other members of the Board and the Chair; however, each director is free to communicate directly with the Chair;

| ● |  | Works with the Chair in the preparation of the agenda for each Board meeting and in determining the need for special meetings of the Board;

| ● |  | Consults with the Chair on matters relating to corporate governance and Board performance;

| ● |  | Leads the deliberation and action by the Board or a Board committee regarding any offer, proposal, or other solicitation or opportunity involving a possible acquisition or other change of control of the Company, including by merger, consolidation, asset or stock sale or exchange, or recapitalization;

| ● |  | In conjunction with the Chair of the Governance and Nominating Committee, oversees and participates in the annual board evaluation and succession planning process;

| ● |  | Participates in the Human Capital Committee’s annual performance evaluation of, and succession planning for, the Chair and CEO; and

| ● |  | Meets with any director whom the Lead Independent Director deems is not adequately performing his or her duties as a member of the Board or any committee.

|  | 31

##### Table of Contents

|  | CORPORATE GOVERNANCE AND BOARD MATTERS

The charter of the Governance and Nominating Committee calls for the annual review of the Lead Independent Director position. The Company believes that having a Lead Independent Director, particularly in presiding over executive sessions of independent directors, effectively encourages full engagement of all directors. Dr. Srikant Datar was elected to serve as ICF’s Lead Independent Director as of May 27, 2021.

Each of our directors, other than Mr. Wasson, is independent and the Board believes that the independent directors provide effective oversight of management. The Board has complete access to the Company’s management team, and the Board and its committees regularly receive reports from management on the Company’s business affairs and the issues it faces.

The Board believes that its programs for overseeing risk, as described under “Risk Oversight” below, would be effective under a variety of leadership frameworks; therefore, this factor does not materially affect its choice of structure.

Risk Oversight

Our business is subject to various types of risk. Some of the Company’s most significant risks are outlined in our 2022 Form 10-K under Item 1A, “Risk Factors.”

Our Board provides guidance to management regarding our strategy, including in connection with review of our results of operations and related trends and factors contributing to or affecting our results, long-term strategy, financial reporting, and risks associated with these aspects of the Company’s business. The involvement of the Board in setting our business strategy is an important part of determining the types and appropriate levels of risk undertaken by the Company.

Management is responsible for the day-to-day management of the risks we face, while the Board, as a whole and through its committees, has responsibility for the oversight of risk management. As described more fully below, the Board fulfills this responsibility both directly and through its standing committees, each of which assists the Board in overseeing portions of the Company’s overall enterprise risk management (“ERM”) program.

The Company’s ERM program is designed to identify, assess, monitor and manage the Company’s risks. As part of the annual ERM program, the Company:

| ● |  | Defines risk profiles and identifies existing and new/emerging risks.

| ● |  | Conducts and completes regular enterprise risk assessments to ascertain and define the most significant risks facing the Company, which incorporate input from multiple levels of management and our Board. This process includes the evaluation and prioritization of the most significant risks facing the Company across major risk categories, and takes into account multiple factors, including the potential impact of risk events should they occur, the likelihood of occurrence and the effectiveness of existing risk mitigation strategies.

| ● |  | Develops action plans to monitor, manage and mitigate risk. The responsibility for managing each of the highest-priority risks is assigned to one or more of the Company’s senior executives.

| ● |  | Includes regular reporting from management to the Board on the status and completion of actions associated with the risks identified as part of the current ERM program. In addition, management provides more detailed briefings throughout the year to the Board regarding the most significant risks identified in the current ERM program.

As described above, the Board, along with the Audit Committee, oversees a number of risks, which include those associated with major operational activities, cybersecurity and risks associated with potential acquisitions. The Audit Committee reviews and evaluates the Company’s overall risk profile, and the procedures and policies implemented by management to identify and manage such risks. The Human Capital Committee is responsible for overseeing the management of risks relating to our compensation plans and arrangements. Under its Charter, the Governance and Nominating Committee generally manages material risks and opportunities associated generally with environmental, social and governance (“ESG”) matters, the independence of the Board and potential conflicts of interest.

Board Evaluation

Each year, the directors undertake an evaluation for the Board and each committee on which they serve that elicits feedback on the performance and effectiveness of the Board and its committees. As part of this evaluation, the directors are asked to consider the role of the Board and its committees, relations with management, composition, and meetings. The responses and comments are compiled by the Corporate Secretary and presented to the Governance and Nominating Committee for initial review. The responses and comments are then presented to each committee and the full Board. Where appropriate, the Governance and Nominating Committee may consider feedback received from the evaluation process when it submits director nominees to the full Board (and, where applicable, recommends assignments to various committees). In addition, every other year as part of the Board evaluation process, the Lead Independent Director and the Governance and Nominating Committee Chair meet individually and hold peer evaluations with each Director. The last supplemental evaluation was conducted in 2020. These supplemental discussions are intended to enhance the existing Board evaluation process and foster even greater discussion regarding the adequacy and effectiveness of the Board and such committees.

Additionally, the Board has conducted and plans to continue to periodically conduct external evaluations by an independent third party. The external evaluations would include interviews with directors and may include interviews with key management personnel, to determine existing strengths of the Board, as well as areas of improvement, to increase overall Board effectiveness.

Mmes. Crouther and Grisé, and Messrs. Mehl, Salmirs and Schulte were the members of our Human Capital Committee during the year ended December 31, 2022. Mr. Schulte’s tenure as a director ended in June 2022. None of them are or were an officer or employee of the Company. None of our executive officers served as a member of the Board or the Human Capital Committee of any entity that has one (1) or more executive officers serving as a member of our Board or Human Capital Committee.

Process for Selecting and Nominating Directors

As noted in the accompanying chart, we will consider candidates for director who are recommended by stockholders. Stockholder recommendations should be submitted in writing to: ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia, 20190, Attention: Corporate Secretary. Such stockholder’s notice shall set forth, for each nominee, all information relating to such person that is required to be disclosed in solicitations of proxies for election of directors pursuant to Regulation 14A under the Exchange Act and pursuant to the Company’s Bylaws (including such person’s written consent to being named as a nominee and to serving as a director if elected). Among other information, the notice shall also include, as to the stockholder giving notice: (i) the name and address of the stockholder; (ii) the class or series and number of shares of the Company which are, directly or indirectly, owned by such stockholder, as well as options, warrants, convertible securities, stock appreciation rights (“SARs”), and similar instruments of the Company (“Derivative Instruments”) that are held by the stockholder; (iii) any proxy, contract, arrangement, understanding, or relationship pursuant to which such stockholder has a right, directly or indirectly, to vote any shares of any security of the Company; (iv) any short interest in any security of the Company directly or indirectly owned by such stockholder; (v) any rights to dividends on the shares of the Company owned beneficially by such stockholder that are separated or separable from the underlying shares of the Company; (vi) any proportionate interest in shares of the

To be eligible to be a nominee for election or reelection as a director of the Company, a person must submit to the Corporate Secretary (in accordance with the time periods prescribed for delivery of notice under the Company’s Bylaws) at the above address a written response to a questionnaire with respect to the background and qualification of such person (which questionnaire shall be provided by the Corporate Secretary upon written request) and a written representation and agreement (in the form provided by the Corporate Secretary upon written request) that such person: (i) is not and will not become a party to (x) any agreement, arrangement, or understanding with, and has not given any commitment or assurance to, any person or entity as to how such person, if elected as a director of the Company, will act or vote on any issue or question (a “Voting Commitment”) that has not been disclosed to the Company or (y) any Voting Commitment that could limit or interfere with such person’s ability to comply, if elected as a director of the Company, with such person’s fiduciary duties under applicable law; (ii) is not and will not become a party to any agreement, arrangement, or understanding with any person or entity other than the Company with respect to any direct or indirect compensation, reimbursement, or indemnification in connection with service or action as a director that has not been disclosed therein; and (iii) would be in compliance, if elected as a director of the Company, and will comply with all applicable publicly disclosed corporate governance, conflict of interest, confidentiality, and stock ownership and trading policies and guidelines of the Company.

Executive Stock Ownership Policy

The Company strives to ensure alignment with stockholder interests by means of ensuring that Company executives have an equity stake in the Company that is consistent with the long-term

performance of the Company. The Executive Stock Ownership Policy, as amended, (the “2018 Executive Stock Ownership Policy”) requires executives to own ICF common stock in a value equal to, or in excess of, the multiple of their annual base salary as shown below. The policy was amended in September 2021 to remove stock options which are both vested and “in the money” from the ownership calculation.

●Executive Chair:* |  | ●5x
●CEO: |  | ●5x
●Other NEOs: |  | ●2x
●Other designated executives: |  | ●1x

*While the policy references an Executive Chair, that position is currently vacant, and we do not currently intend to fill that position.

The following types of equity count toward satisfying the stock ownership requirement: (i) any shares held outright as a result of vested RSUs or PSAs, (ii) shares acquired through the exercise of stock options or purchased through the Company’s employee stock purchase plan qualified pursuant to Section 423 of the Code or through the open market, and (iii) unvested RSUs. In addition, designated executives are required to hold all shares acquired from vested RSUs, vested PSAs and stock option exercises, net of shares withheld for taxes, until they meet the 2018 Executive Stock Ownership Policy requirements.

Stock ownership levels are to be achieved within five (5) years of appointment or designation, as the case may be. For executives appointed or designated mid-year, such levels, if not achieved by their fifth anniversary of becoming such an executive, are to be achieved no later than December 31 of that fifth year. As of April 3, 2023, each of our NEOs either met these stock ownership guidelines or is expected to meet the applicable ownership guidelines within their specified time period.

Board Stock Ownership Guidelines

The Board believes that its members should be incentivized to focus on the Company’s long-term stockholder value. As such, the Board adopted a Board member stock ownership policy establishing, as a guideline (but not an absolute requirement), that non-employee members of the Board are expected to own shares of Company common stock valued at five (5) times such director’s annual cash retainer fees, which may include shares of unvested restricted stock (i.e., directors are strongly encouraged to hold common stock valued at $425,000). Such ownership level is to be achieved over a period of four (4) years after becoming a member of the Board. As of April 3, 2023, each of our non-employee directors either met these stock ownership guidelines or is expected to meet the ownership guidelines within the specified time period.

Director Continuing Education

The Board believes that director continuing education is important for maintaining a current and effective Board and has

|  | CORPORATE GOVERNANCE AND BOARD MATTERS

adopted a Director Continuing Education Policy. The Company’s policy encourages directors to participate in continuing education and accredited director education programs, with the intent of becoming and remaining well informed about the Company, its industry and business, its relative performance to its competitors and regulatory issues and economic trends affecting the Company. The Governance and Nominating Committee reviewed education opportunities available for Board members and has identified a series of courses and programs that would be beneficial to Directors in their service on the ICF Board and Board committees.

Prohibitions on Derivatives Trading, Hedging and Pledging

Pursuant to the Company’s Policy on Insider Information and Securities Trading (“Policy on Insider Information”) the Company considers it improper and inappropriate for any employee, officer or director of the Company to engage in short-term or speculative transactions in the Company’s securities. The policy specifically prohibits directors, officers and other employees from engaging in short sales of the Company’s securities and transactions in puts, calls or other derivative securities (sometimes referred to as “hedging”). In addition, stock grant agreements prohibit the pledging or assignment of awards. Each of the NEOs and directors complied with this policy during fiscal year 2022.

Previously, individual stock grant agreements prohibited the pledging or assignment of stock grants. In April 2020, the Company adopted an updated and more comprehensive Hedging and Pledging Transactions Policy (the “Hedging and Pledging Policy”), which is applicable to our directors, Section 16 reporting officers, and other designated officers of the Company, and which was further updated in September 2020. The new policy establishes a restriction on short sales and other hedging transactions, pledging and the establishment of margin accounts.

Directors and other covered officers who established pledging arrangements within the prior limitations will be prohibited from establishing new arrangements and are encouraged to wind down and conclude any legacy arrangements. There are currently no directors with any legacy pledging arrangements in place.

Stockholder Engagement and Communications with the Board

Management and members of the Board endeavor to engage with a significant portion of our stockholders each year. This is done through multiple forums, including quarterly earnings presentations, our annual meeting of stockholders, our annual Investor Day, investor conferences and web communications, as well as our SEC filings, our annual report and our proxy statement. Additionally, you may contact the Board by sending a letter marked “Confidential” and addressed to the Board, ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia, 20190, Attention: Corporate Secretary. In accordance with instructions from the Board, the Corporate Secretary reviews all correspondence, organizes the communications for review by the Board, and posts communications to the full Board, specific committees or individual directors, as appropriate. Communications that are intended specifically for the Lead Independent Director, the independent directors or non-management directors should be marked as such.

Political Contributions and Lobbying

The Company encourages our employees to be active in civic and community activities, including participation in the political and democratic process. Our policy also encourages employees to ensure that those individual activities are kept separate from their work for the Company.

The Company does engage, from time to time, in discussions with various levels of governments on public policy issues. While our activities in this area are fairly limited, when we determine it is in the best interest of the Company to do so, we work with governments to provide information and perspective that support our point of view, including through government relations professionals. The Company, and those who act on our behalf, meet registration, disclosure and other reporting requirements regarding these activities.

Director Compensation

The following discussion outlines the compensation that was earned by our non-employee directors during 2022. The compensation of our Board is evaluated from time to time by our Governance and Nominating Committee.

Directors who are employed by us do not receive additional compensation for their service on the Board. All directors are entitled to reimbursement of expenses for attending each meeting of the Board and each committee meeting.

All director compensation, other than the director equity grant, is paid in cash, on a quarterly basis in advance. Cash fees are pro-rated on the date of any directors’ departure from the Board for an upcoming quarter; provided that a director that serves until the annual meeting of stockholders shall receive the full amount of cash fees for that quarter. Cash fees for new directors are pro-rated based upon the date of the director’s appointment to the Board.

Cash retainer fees for 2022 were as follows:

Annual Retainer for Non-Employee Director: |  |  |  |  |  |  |  |  |  | $ | 85,000 |
Additional Annual Retainer for Lead Director: |  |  |  |  |  |  |  |  |  | $ | 30,000 |
Committee Retainers: |  |  | Chair |  |  |  |  |  |  |  | Member |
Audit Comm. |  | $ | 20,000 |  |  |  |  |  |  | $ | 12,000 |
Human Capital Comm. |  |  | 10,000 |  |  |  |  |  |  |  | 8,000 |
Governance & Nominating Comm. |  |  | 10,000 |  |  |  |  |  |  |  | 8,000 |

The Board approved an increase in the annual cash retainer for non-employee directors in 2022, from $75,000 to $85,000 following consideration of a director pay study conducted by the Company’s independent compensation consultant. The study compared the Company’s director compensation program with those of comparable companies, including our established Peer Group, and determined it was appropriate to increase the retainer.

In addition to the cash retainers, the directors are granted an annual equity award, in the form of a grant of restricted stock units, vesting quarterly over a one-year period. The number of shares granted is determined by dividing $145,000 by the closing market price of ICFI common stock on the first business day of July following the annual meeting of stockholders, with the award rounded down to the nearest whole share and the balance paid in cash.

Code of Ethics

The Company has a Code of Ethics that is designed to promote the highest standards of ethical conduct by the Company’s directors, executive officers and employees. The Code of Ethics requires that the Company’s directors, executive officers and employees avoid conflicts of interest, comply with all laws and other legal requirements, conduct business in an honest and ethical manner, and otherwise act with integrity and in the Company’s best interest. Under the terms of the Code of Ethics, directors, executive officers and employees are required to report any conduct that they believe in good faith to be an actual or apparent violation of the Code of Ethics. The Code of Ethics is updated from time to time to reflect changes in laws, best practices and the Company’s business.

The Code of Ethics and all Board committee charters are posted in the “Investors – Corporate Governance” portion of our website (www.icf.com). A copy of any of these documents is available in print (free of charge) to any stockholder who requests a copy by writing to: ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia, 20190, Attention: Corporate Secretary. The Company will disclose on its website at www.icf.com, to the extent and in the manner permitted by

Item 5.05 of Form 8-K, the nature of any amendment to the Code of Ethics (other than technical, administrative, or other non-substantive amendments) and our approval of any material departure from a provision of the Code of Ethics that has been made known to any of our executive officers.

Certain Relationships and Transactions with Related Persons

Our Code of Ethics, which applies to all directors, executive officers and employees, emphasizes the importance of avoiding situations or transactions in which personal interests interfere with the best interests of us and/or our stockholders. In addition, the Board has a written policy and process for reviewing and evaluating interested director transactions designed to alert the Board, and in particular the Governance and Nominating Committee, of material transactions involving the Company and directors and their affiliates so that the Board may be aware of and consider such transactions in advance, on a case-by-case basis. As to matters coming before the Board in which individual directors may have a personal interest, the Board has adopted procedures to ensure that all directors voting on such a matter disclose any personal interest, abstain from voting on the matter, and discuss the transaction with counsel if necessary. The Board has delegated the task of discussing, reviewing, and approving transactions between the Company and any of our executive officers or Board members to the Governance and Nominating Committee.

There have not been any transactions during the last fiscal year to which we have been a party, in which the amount involved in the transaction exceeded $120,000, and in which any of our directors, executive officers or holders of more than five percent (5%) of our capital stock had or will have a direct or indirect material interest other than equity and other compensation, termination, change-in-control and other arrangements, which are described in the section captioned “Executive Compensation—Potential Payments upon Termination or Change of Control.” of this Proxy Statement.

Other Transactions Considered for Independence Purposes

For each director and nominee for director who is identified as independent, the SEC rules require the description of transactions, relationships or arrangements that are not required to be disclosed as related person transactions, but that were considered by the Board in determining that the director is independent. There were no transactions that the Company believes are related person transactions; however, there were transactions with independent directors that did not rise to the level of a related person transaction, but that were considered for independence purposes.

Governance ensures we fulfill our commitments. While governance involves the actions and behaviors of all employees, it is a particular responsibility of our leaders as they guide ICF in accordance with our values. Our ESG program receives oversight from the Board, the CEO, and the ESG Council—among other governing bodies. The Board considers ESG matters as part of ICF’s enterprise risk management process and long-term strategic planning. It receives briefings on ESG matters from its committees and management, including updates regarding ICF’s climate-related, cybersecurity, and other risks and opportunities.

ICF’s Chair also serves as President and CEO of the firm and is intimately familiar with its operations. ICF’s CEO serves as a connection point between the Board’s oversight and the management team’s execution of business activities and operations. The CEO’s ESG responsibilities include oversight of risks (including climate and cybersecurity), oversight of strategy (including climate and resilience), oversight of codes (such as inclusive HR policies), approval of resources (for example, to manage and reduce GHG emissions and purchase high-quality offsets), among other ESG matters.

Impact for Good in 2022 Of our $1.78 billion revenue, ICF estimates that at least: $906 million was derived from services delivering positive social impact—health, education, development and social justice programs. $665 million was generated from services creating positive environmental impact—reducing energy consumption, managing carbon footprint and protecting natural resources. The balance of other work was also socially responsible and—although not directly supporting social impact or sustainability efforts—consistent with ICF’s commitment to make a positive social and sustainable impact.

The ESG Council supports the integration of ESG principles into our business strategy. It oversees ESG reporting and reviews recommendations from the corporate responsibility steering committee. It reports to the CEO, is chaired by the executive vice president for corporate strategy and is composed of senior executives. Below is an organization chart and a description of the role of each member.

ESG Council in context |  | ESG Council participation
| HR/D&I: |  | People policies, diversity and inclusion, employee engagement
| Corporate Strategy: Climate Strategy: |  | Business risks and opportunities, impact and competition Plans for thriving in a carbon-constrained future
| Corporate Responsibility: |  | Stakeholder perspectives, corporate philanthropy and ESG reporting
| Legal: |  | Compliance; assurance and corporate governance
| Finance: |  | Reporting and resources

Reporting for Transparency. Productive relationships with stakeholders require trust. To that end, we report annually on our performance on important measures not currently required in financial reporting, including our progress toward goals regarding human capital management, sustainability, philanthropy and other targets. We report on ICF’s corporate sustainability strategy and performance in alignment with the Task Force for Climate-related Financial Disclosure (“TCFD”), the Sustainability Accounting Standards Board (“SASB”), the UN Global Compact, and progress toward our Science-Based Targets, among other global sustainability goals. This information and more can be found in our latest Corporate Citizenship Report (published July 2022 and available on our Company website at www.icf.com, under “About ICF, Corporate Citizenship”). Our report won 4 platinum MarCom Awards for excellence in corporate citizenship reporting. Below are some highlights of our performance. |  |  |  | CDP Climate Leader, 5th Year For the 5th consecutive year ICF scored A- or A on our annual climate change report.

Carbon Targets and Performance. ICF recognizes the risks and opportunities due to climate change caused by increased carbon emissions. ICF’s climate experts communicate those opportunities and risks to our executive leaders and our Board. Since 2006 ICF has committed to be carbon neutral, which we achieve through three activities:

| • |  | Reduce. Lease more efficient facilities and consolidate where feasible. Maximize virtual tools to travel less. Engage our people to work more sustainably. Purchase more eco-friendly products. Encourage partners in our value chain (suppliers and clients) to manage their carbon footprint.

| • |  | Buy renewable energy. Purchase Renewable Energy Certificates equivalent to 100% of the electricity used by our global operations.

| • |  | Buy carbon offsets. After taking the measures above, we buy high-quality carbon offsets equivalent to the measured carbon emissions of our global operations: all of scope 1 and scope 2 emissions, plus a significant portion of scope 3 emissions from business travel and employee commuting.

By way of background, Scopes 1, 2 and 3 referenced in this section refer to defined terms established by the Greenhouse Gas Protocol. In this regard, Scope 1 refers to direct greenhouse gas emissions from sources owned or controlled by ICF; Scope 2 refers to greenhouse gas emissions from purchased electricity; and Scope 3 refers to greenhouse gas emission sources beyond the walls of our facilities. With respect to Scope 3, prior to 2018, ICF measured business travel and commuting only. Beginning in 2018, we began to measure emissions embedded in our purchased goods and services.

Since establishing our baseline emissions in 2013, we have shrunk our carbon footprint by every measure. We reduced carbon emissions in absolute terms, as well as intensity per employee, revenue, and leased space (see graphic below). We achieved this ahead of our target. In 2020, ICF committed to set an ambitious science-based carbon-reduction target, an approach to a zero-carbon

|  | 42

##### Table of Contents

|  | CORPORATE GOVERNANCE AND BOARD MATTERS

economy that boosts innovation and drives sustainable growth. Such targets are based on the concept of a global carbon budget that will limit global warming to well below 2°C. In March 2021, the Science Based Targets initiative approved our target, adding ICF to the list of pioneering companies driving change to a zero–carbon economy.

ICF Grows While Emissions Decline, 2013-2021

Emissions depicted include all of scope 1 and scope 2, plus a significant portion of scope 3, including emissions from business travel and employee commuting.*

* Does not include emissions from purchased goods and services, which we began estimating in 2018.

Our Strength is our People. People join ICF to make a difference and to work on impactful projects that change the world now and for generations to come. Attracting talent who want to make an impact and investing in the growth of our people to be their best selves is what sets us apart from our competition and helps us deliver outstanding results. We work hard to maintain a stimulating, supportive, and respectful environment for our 9,000+ employees where everyone can thrive and express themselves freely. The results of our recent employee engagement survey reinforced the strong culture that makes our employees want to stay and grow a career here. We’re proud that 86% of respondents believe their values aligned with the values of ICF and 87% of respondents feel they have a flexible schedule that meets their personal needs. Both of these results were a full 16% above industry average.

In 2022, we accelerated the transformation of our people plans, programs, and policies. We continued to implement a multi-pronged strategy to adapt with the evolving needs and expectations of our people. Our strategy focuses on evolving our culture with the changing world, optimizing our recruiting efforts to bring the best talent in to the organization, reimagining the talent experience as an employee, growing our total rewards offerings, and advancing in our diversity, equity, and inclusion (“DEI”) journey. We’re committed to enabling our employees to belong, grow, and thrive both personally and professionally. Inclusion is a top priority. We have eight Employee Community Networks (“ECNs”) to foster support, networking, mentoring, professional development, community outreach, and business impact. One in four of our employees are involved in at least one ECN. We have also put in place a deliberate and results-focused DEI recruiting strategy to attract top talent from diverse recruiting sources to ICF. Explore our 2022 Inclusion Report to learn more about our continued journey and the strength of our inclusive culture. |  |  |  | Recognized Diversity Leader As a purpose-driven company with a strong culture and underlying values, we prize diversity, opportunity, equality and respect. And because of that, ICF was recognized by Forbes Magazine in 2022 and 2021 as one of America’s Best Employers for Diversity. Forbes’ recognition highlights our strengthened commitment to inclusion.

We enable our employees to grow their personal and professional skills through experiential learning, formal training, and mentoring opportunities. We encourage our employees to be well-rounded and to drive their own career growth. We encourage

quarterly impact conversations between employees and managers that are future-looking conversations focused on growth and career development opportunities. We also deliver customized, blended digital and instructor-led programs in key topics like business development, project management, and people management. Our learning catalog has over 30,000+ training courses available and we also offer tuition reimbursement. In 2022, our annual mentoring program had its largest cohort with 515 mentoring pairs. A key focus area this year was to continue building our pipeline of tomorrow’s leaders. We expanded our leadership development curriculum and were able to triple our reach to emerging leaders at various stages of their career.

We want to help employees thrive physically and professionally, find emotional balance, build financial security, and stay connected. This year we launched a wellbeing platform, powered by Virgin Pulse. Nearly 40% of eligible employees are active on the platform, more than triple the vendor’s benchmark during the first year of implementation. We conducted four company-wide challenges this year. One challenge resulted in over 47 million steps, equating to nearly one loop around our globe. When our employees are at their best, it impacts how they engage at work, with their family, and the larger community.

Advancing Global Goals. ICF is a signatory of the UN Global Compact on human rights, labor, environment, and anti-corruption. We are committed to making these principles part of our strategy, culture, and day-to-day operations. Through our operations, client services, and philanthropy, we champion the UN Sustainable Development Goals. With our clients, we are tackling climate change, improving health and education, reducing injustice and inequality, and spurring economic growth. The exhibit below provides a snapshot of our support for the UN Sustainable Development Goals (“SDGs”).

Compensation Discussion and Analysis

NEOs
●John Wasson, Chair, President and CEO
●James Morgan, Executive Vice President and COO
●Barry Broadus, Senior Vice President and CFO
●Mark Lee, Executive Vice President
●Anne Choate, Executive Vice President

In this section, we describe the material components of the Company’s executive compensation program for our NEOs, whose compensation is set forth in the 2022 Summary Compensation Table and other compensation tables contained in this Proxy Statement.

We also provide an overview of our executive compensation philosophy and executive compensation program. In addition, we explain how and why the Human Capital Committee (for purposes of this CD&A, the “Committee”) arrived at the specific compensation decisions regarding our NEOs for fiscal year 2022.

The Committee has responsibility for establishing, implementing, and monitoring adherence to the Company’s compensation philosophy. The Committee strives to ensure that the total compensation paid to the Company’s executives is fair, reasonable, and competitive. The types of compensation and benefits provided to the Company’s NEOs are similar to those provided to other members of the Company’s executive leadership team.

Fiscal 2022 – Financial Highlights

In 2022, ICF won a record $2.3 billion in contract awards, laying the foundation for strong future growth. Financial highlights for 2022 included the following:

| ● |  | Total revenues increased 14.6% to $1.78 billion.

| ● |  | Service revenue increased 15.8% to $1.29 billion.

| ● |  | Operating income decreased 2.0% to $108.8 million.

| ● |  | Net income decreased 9.7% to $64.2 million.

| ● |  | Diluted earnings per shares (“EPS”) was $3.38 for 2022, inclusive of $1.31 of tax-effected special charges, of which the overwhelming majority were facility, severance, and mergers and acquisitions-related charges. This compares to $3.72 per diluted share for 2021, inclusive of $0.63 of tax-effected special charges.

We implemented a return-to-office strategy to provide employees the opportunity to return to our offices as they re-opened in 2022. To prepare, we provided information and resources to our managers and set up technology in offices to ensure a productive hybrid work environment.

Compensation Highlights

The Committee took the following actions during fiscal year 2022 and at the beginning of fiscal year 2023 to maintain governance best practices and the pay-for-performance nature of our executive compensation program:

| ● |  | Continued utilizing performance share awards (“PSAs”) as a key component of ICF’s long-term incentive program. PSAs are performance contingent awards under which executives may earn shares depending on the Company’s actual performance against pre-established performance measures. The performance periods of the PSAs are long-term and align executives’ interests with the interests of long-term stockholders.

| ● |  | Conducted an annual review to ensure compliance with stock ownership guidelines for our NEOs. As of April 3, 2023, each NEO met the stock ownership guidelines or is expected to meet the applicable stock ownership guidelines within the specified time period.

| ● |  | Continued the performance focus in the Company’s Annual Incentive Plan (as defined below), rigorously linking pay to performance. Annual threshold, target and maximum performance goals were established with appropriate incentive payouts at each level.

| ● |  | Continued the annual review of NEO compensation against best practices and market data.

| ● |  | Extensively reviewed external executive compensation trends to ensure that the Company’s executive compensation practices align with market best practices. The peer group and other market data from nationwide salary services are used to provide a relevant basis for determining executive pay levels.

| ● |  | Supported the continuation of an annual, non-binding, advisory vote of the Company’s stockholders regarding the Company’s overall pay-for-performance named executive officer compensation program (“Say on Pay”). The Say on Pay vote at the Annual Meeting (Proposal 3) will be the thirteenth consecutive annual Say on Pay vote by stockholders.

Stockholder-Aligned Executive Compensation Practices

The Company implements and maintains leading practices in its executive compensation programs as outlined below:

What We Do

| ✓ | Our pay-for-performance named executive compensation program is presented for a non-binding advisory vote during the annual meeting of stockholders.

| ✓ | Target compensation is analyzed and compared against peer data and regressed market-based benchmarks. Actual compensation may increase or decrease depending on performance.

| ✓ | Our selection of peer companies is balanced so the Company’s revenue is close to the median of the peer group. The peer group is reviewed annually to ensure appropriate companies are included and others removed if involved in mergers and acquisitions.

| ✓ | The Committee has engaged an independent compensation consultant.

| ✓ | We require one (1) year minimum vesting for our equity awards, except for grants totaling no more than a maximum of five percent (5%) of the shares available for grant.

| ✓ | Our annual equity award grants provide for vesting over three (3) years for RSUs and PSAs.

| ✓ | All NEOs and other designated executive officers are subject to stock ownership requirements which further align their interests with stockholders.

| ✓ | The severance agreements with the NEOs include a “double-trigger” for any severance benefits payable following a change of control.

| ✓ | Our 2018 Incentive Plan includes “double trigger” accelerated vesting for equity awards in the event of a change of control of the Company plus termination within twenty-four (24) months following the change of control for our NEOs.

| ✓ | Our clawback policy covers cash and equity awards and applies to all employees.

| ✓ | Severance arrangements with NEOs except the CEO include additional “clawback” provisions.

| ✓ | We have no material perquisites.

| ✓ | We review tally sheets for each executive annually to ensure there is sufficient retention capability built into the pay package, and that the NEOs have similar interests as stockholders.

What We Don’t Do

| × | Our executive officers and directors are prohibited from hedging Company shares.

| × | Individual equity grant agreements prohibit the pledging or assignment of stock grants. We have also adopted the Hedging and Pledging Policy that has full restrictions on pledging, assignment of stock grants and establishment of margin accounts.

| × | Our 2018 Incentive Plan prohibits the repricing of equity awards or cash-buyout of underwater stock options and PSAs.

| × | Our 2018 Incentive Plan does not allow the recycling of shares used to exercise options or sold to pay withholding taxes.

| × | We do not issue dividend payments on unvested equity awards.

| × | We do not provide tax gross-ups.

Compensation Philosophy and Objectives

The fundamental objectives of the Company’s compensation philosophy remain:

Reward performance and contribution to our business. Our compensation programs are designed to reward extraordinary performance with higher compensation. Likewise, where individual performance falls short of expectations and/or Company performance lags behind budgeted plan performance, the programs deliver lower or no payouts.

Pay-for-performance and retention must be balanced. Although performance is a key element of the Company’s compensation philosophy, in order to attract and retain a highly skilled work force we must remain competitive with the pay of our peer companies with which we compete for talent. We assess competitiveness using a peer group where the Company’s revenue is close to the peer group median. In addition, we review market benchmarks for pay across several large global compensation surveys, regressed for our company size.

|  | 51

##### Table of Contents

|  | EXECUTIVE COMPENSATION

Compensation should be aligned with stockholder interests. Key employees should receive a substantial proportion of their compensation as equity in order to align their individual financial interests with the financial interests of our stockholders.

The relationship between overall Company goals and each individual’s personal goals should be clear. Employees should be able to easily understand how their efforts can affect their pay, both directly through individual performance and indirectly by contributions to the business unit and the Company achieving strategic and operational goals.

Provide no material perquisites for NEOs. Our compensation programs include only those perquisites commonly provided to attract and retain the NEOs and/or improve a NEO’s ability to carry out responsibilities safely and effectively.

Guidelines for ICF’s Executive Officer Compensation Program

Development of Financial/Strategic Performance Goals. Each year, Company management presents its budget, revenue forecast, and strategy to the Board in the November/December timeframe, allowing the Board and management to develop a consensus on financial and strategic goals for the following year. These goals are reflected in the compensation program for the following year and the metrics that will drive individual performance goals, total compensation targets and actual compensation levels.

|  | EXECUTIVE COMPENSATION

Elements of Compensation Program. Consistent with prior years, the principal components of our NEOs’ 2022 compensation included: (i) base salary, (ii) short-term incentive or bonus (our Annual Incentive Plan, as defined below) and (iii) long-term incentive equity awards. The following table outlines the key components of our compensation program for our NEOs (excluding health and similar benefits, which are generally available to all employees).

|  | Compensation Element |  | Purpose |  | Design
Fixed Component |  | Base Salary |  | Provide a pay opportunity that is generally competitive with other companies with which we compete for talent |  | Based on performance, length of time in position and pay relative to market
Short-Term Incentive Performance-Based Component |  | Annual Incentive Plan |  | Optimize the profitability and growth of the Company through incentives consistent with the Company’s goals Link and align the personal interests of participants with an incentive for excellence in individual performance Promote collaboration and teamwork |  | Financial performance targets are established at the beginning of each fiscal year Actual awards will be based on the performance of the Company and the executive against the fiscal year’s goals 80% of award based on financial targets and 20% based on individual performance
Long-Term Incentive Performance-Based Component |  | Long-Term Incentive Equity Awards |  | Enhance the link between the creation of stockholder value and long-term executive incentive compensation Encourage participants to focus on long-term Company performance Provide an opportunity for increased equity ownership by executives Provide a retention tool for key talent |  | Grants are performance-based and service-based as follows: 50% performance 50% retention 50% of award = PSAs with 3-year cliff vesting based on performance metrics •  2-year adjusted EPS goal •  3-year rTSR goal as a modifier 50% of award = RSUs with back-loaded 3-year vesting at 25%, 25%, 50% per year

Actual pay vs. target for the short-term incentive and the long-term incentive, and the resulting mix of pay components versus target mix, will vary due to the performance of the Company and the NEOs. This provides the Committee flexibility in awarding incentive compensation and making pay adjustments to maintain competitive levels of total compensation. For each NEO, the Committee reviews a tally sheet which assigns a dollar amount to each identified compensation element as well as current and potential wealth accumulation based on outstanding equity awards. The Committee believes the tally sheet is a useful tool to ensure there is sufficient retention capability built into existing pay packages and that the NEOs have a stake in the Company’s performance, consistent with the interests of Company stockholders.

Assessment of Annual Performance.

For purposes of compensation awards:

The Committee reviewed various performance summaries and reports and made recommendations to the Board regarding compensation for the Chair, President and CEO (for purposes of this CD&A, the “CEO”). In the case of executives other than the CEO, the CEO reviewed the performance of the executive team, provided a summary of the fiscal year accomplishments by the executive team and Company as a whole to the Committee, and made recommendations to the Committee based on these reviews and an analysis of competitive market data. The Committee took this input into account when determining compensation for other NEOs.

Impact of Acquisitions. Because strategic merger and acquisition transactions have historically been an integral element of the Company’s growth strategy, our executive compensation structure reflects the time and effort needed to successfully identify, negotiate and integrate acquisitions. Typically, our executives are rewarded for this element through share price appreciation in the long-term incentive component rather than receiving an explicit cash award tied to merger and acquisition transactions. However, should a transaction exceed 10% of the Company’s prior year’s gross revenue, then, based on the timing and size of the acquisition, executives may be given an opportunity to earn an extra short-term incentive with no change in previously established performance targets.

Implementing Our Objectives

Use of Market Data

ICF uses regressed survey data from several globally recognized compensation surveys to supplement peer group data. This is especially helpful in addressing NEO roles other than the CEO and CFO role. The other executive roles are not always consistent with the third, fourth and fifth paid NEOs in proxy filings of our peers in the peer group. Therefore, market data is reviewed to support the peer group data.

Use of Peer Company Data

The Committee annually reviews our peer group and the methodology for choosing participating companies. The five (5) guiding principles used for the selection of peer companies are:

| ● |  | Size: We aim for the overall peer group median to approximate our revenue, and we generally select peers between 0.5x to 2.5x of our revenue. In some instances, a peer may fall outside this range if it is otherwise deemed a strong business and talent comparator.

| ● |  | Similar business characteristics: Selected peer companies either compete with us or have similar market demands.

| ● |  | Talent pool: Selected peer companies compete with us for talent.

| ● |  | External constituents: Some selected peer companies were named by our equity research analysts as peers or are other companies that identify ICF as a peer.

| ● |  | Sectors: In addition to focusing on Professional Services (our designated Global Industry Classification Standard), other relevant sectors, including IT Services, Health Care Technology and Commercial Services were also reviewed.

We believe the companies selected for our 2022 peer group, as listed below (the “2022 Peer Group”), continue to reflect our current mix of services.

Annual Compensation Practice Review

In anticipation of the upcoming executive compensation review cycle, the Committee continued its engagement of Aon Human Capital Solutions Practice, a division of Aon plc (“Aon”), as its independent compensation consultant to assist the Committee in reviewing the Company’s compensation policies and practices for 2022. In particular, the Committee asked Aon to discuss current executive compensation trends and provide feedback regarding management’s competitive assessment for executive positions. For additional information regarding Aon and its relationship with the Committee see “Role of Compensation Consultants in Compensation Decisions” below.

In making its compensation determinations, the Committee reviewed and assessed the analysis and recommendations of Company management. The Committee also requested the views of Aon and obtained an assessment of management’s analysis from management’s executive compensation consultant, Semler Brossy Consulting Group, LLC (“Semler Brossy”). In connection with its evaluation of management’s recommendations, as well as its discussions with Aon and Semler Brossy, the Committee determined that, while the peer group compensation data was the appropriate primary focus, the Company does compete with many other companies for top executive-level talent. Thus, the peer group assessment is just one of many inputs into the Committee’s decisions.

Role of Management in Compensation Decisions. In early 2022, the Committee made compensation determinations for all NEOs with respect to 2022 compensation. In the case of executives other than the CEO, the CEO reviewed the performance of the executive team, provided a summary of the fiscal year accomplishments by the executive team and Company as a whole to the Committee, and made recommendations to the Committee based on these reviews and an analysis of

competitive market data. The Committee considered the performance of the Company and of the CEO and made recommendations to the Board regarding their compensation. The Committee took into account input from the CEO with respect to the approval of compensation for the other NEOs.

In late February 2023, the Committee made compensation determinations for all NEOs with respect to 2023 compensation.

Role of Compensation Consultants in Compensation Decisions. In retaining Aon in 2022, the Committee determined, and periodically re-assesses such determination, that Aon’s engagement does not present any conflicts of interest. In making this determination, the Committee considered the following factors, consistent with SEC requirements:

| (i) | the provision of other services to the Company by Aon (including, without limitation, the engagement of Aon by the Governance and Nominating Committee);

In 2022, Aon continued to serve in an advisory capacity to review and discuss with the Committee and/or the Committee Chair the competitive assessment performed by the Company’s management, offer suggestions, and provide insight into market compensation trends.

In addition, as noted above, management retained Semler Brossy to assist in developing its recommendations to the Committee regarding compensation benchmarking, compensation practices, short-term incentive design, and long-term incentive design, particularly the Performance Share Program.

The Committee considered management’s assessment and recommendations, as well as the information provided by both Aon and Semler Brossy (with respect to management’s assessment), in making its compensation determinations. However, as specified in its charter, the Committee retains final approval of all material elements of executive compensation, with the exception of the CEO compensation, which is approved by the Board.

2022 Say on Pay Vote

At the Company’s 2022 annual meeting of stockholders, approximately 97% of the votes cast on the Say on Pay proposal were voted in favor of our overall pay-for-performance NEO compensation program. The Human Capital Committee and the Board believe this affirms the stockholders’ strong support of the Company’s approach to NEO compensation.

Executive Compensation Components

For the fiscal year ended December 31, 2022, the principal components of compensation for our NEOs included: (i) base salary; (ii) short-term incentive (our Annual Incentive Plan); and (iii) long-term incentive equity awards.

For the NEOs, the Committee has discretion with respect to the size, types, amounts, and principal components of compensation,

and, in the case of cash bonuses and equity awards, whether to make any available. For incentive compensation, the Committee establishes pre-determined percentage weights for each component of the Annual Incentive Plan, and pre-determined percentage weights for equity awards. The following section summarizes the role of each compensation component and how decisions are made for the NEOs.

Base Salary

The Committee annually reviews the salaries of our NEOs. In considering salary adjustments, the Committee takes into account individual performance, years of experience in the role and changes in job responsibilities. All amounts were determined considering performance and market alignment with peer group and market survey data. Annual base salaries for 2021 and 2022 are shown below. The larger increase for Mr. Wasson was to acknowledge his continued development in the CEO role since his appointment in late 2019 and to move his base salary closer to the median pay in peer group and market survey data.

ANNUAL BASE SALARY |
Executive |  | 2021 Base Salary |  |  | 2022 Base Salary |  |  | 2022% Increase |
John Wasson |  | $ | 900,000 |  |  | $ | 970,000 |  |  |  | 7.78% |
James Morgan |  | $ | 590,929 |  |  | $ | 616,044 |  |  |  | 4.25% |

Mark Lee |  | $ | 467,500 |  |  | $ | 486,200 |  |  |  | 4.00% |
Bettina Welsh (2) |  | $ | 451,000 |  |  | $ | 451,000 |  |  |  | 0.00% |

(1) In 2022, Mr. Broadus and Ms. Choate became NEOs.

(2) Ms. Welsh stepped down as CFO in February 2022 and served in an advisory capacity for transition of her duties until she departed ICF in April 2022.

Short-Term Incentive Compensation

Both cash bonuses and equity awards are made pursuant to our 2018 Incentive Plan. The 2018 Incentive Plan is designed to: (i) optimize the profitability and growth of the Company through incentives consistent with the Company’s goals; (ii) link and align the personal interests of participants with an incentive for excellence in individual performance; and (iii) promote teamwork.

Annual Incentive Plan for 2022. Based on the market alignment with peer group, market survey data, and performance the Committee concluded that target cash incentive awards as a percentage of base salary for the 2022 Company’s short-term incentive or management bonus program (the “Annual Incentive Plan”) would remain generally the same in 2022 as they were in 2021, except for a competitive market update for the CEO, as shown below.

ANNUAL INCENTIVE PLAN TARGETS (as a percentage of Base Salary) |
Executive |  | 2021 Target |  |  | 2022 Target |
John Wasson |  |  | 110% |  |  |  | 115% |
James Morgan |  |  | 70% |  |  |  | 70% |

(2) In 2022, Ms. Welsh stepped down as CFO and served in an advisory capacity for transition of her duties until she departed ICF.

Consistent with prior years, our 2022 Annual Incentive Plan is weighted eighty percent (80%) on financial performance tied to financial and strategic goals and weighted twenty percent (20%) on individual performance. The individual portion is contingent on achievement of non-financial goals approved by the Committee. The Committee sets each of the goals at levels that it believes are attainable, but which still require consistently high-level performance by each executive.

The financial portion (80%) for NEOs excluding Mr. Lee and Ms. Choate is based on the following:

2022 FINANCIAL PERFORMANCE FACTORS - CORPORATE |
|  | Performance Range |  | Threshold Payout |  |  | Target Payout |  |  | Maximum Payout |  |  | Weighting |
Adjusted EPS |  | 85% - 115% |  |  | 50 | % |  |  | 100 | % |  |  | 200 | % |  |  | 50% |
Company Gross Revenue |  | 80% - 125% |  |  | 40 | % |  |  | 100 | % |  |  | 125 | % |  |  | 30% |
Total Financial Goals: |  |  |  | 80% |

The financial portion (80%) for Mr. Lee and Ms. Choate as Group Leaders is based on the following:

2022 FINANCIAL PERFORMANCE FACTORS – GROUP LEADER |
|  | Performance Range |  | Threshold Payout |  |  | Target Payout |  |  | Maximum Payout |  |  | Weighting |
Adjusted EPS |  | 85% - 115% |  |  | 50 | % |  |  | 100 | % |  |  | 200 | % |  |  | 30% |
Company Gross Revenue |  | 80% - 125% |  |  | 40 | % |  |  | 100 | % |  |  | 125 | % |  |  | 15% |
Group Gross Revenue |  | 80% - 125% |  |  | 40 | % |  |  | 100 | % |  |  | 125 | % |  |  | 10% |
Group Operating Margin |  | 85% - 115% |  |  | 50 | % |  |  | 100 | % |  |  | 200 | % |  |  | 25% |
Total Financial Goals: |  |  |  | 80% |

For 2022, we maintained a performance threshold for Gross Revenue of 80%, which allows for a 40% payout. Performance was measured on a straight-line interpolation between 2022 threshold of 80% and original threshold of 90%, and any performance above 90% was measured on the straight-line interpolation between 90% and 125%. The current performance threshold and payout factor for EPS remained unchanged.

Performance between threshold and maximum levels for the 2022 Annual Incentive Plan is determined by straight-line interpolation between the targeted amounts. Performance below any threshold level results in no bonus amount for that performance factor.

The 2022 Company performance factors and actual results, as described herein, are shown in the following table. Group specific goals are not disclosed, as doing so could cause competitive harm.

2022 FINANCIAL PERFORMANCE GOALS |

| (3) | In 2022, Ms. Welsh stepped down as CFO and served in an advisory capacity for transition of her duties until she departed ICF.

With respect to each NEO’s individual performance, the Committee’s payout determinations considered each executive’s contributions toward the individual non-financial goals established at the start of the year. Each NEO was assigned individual goals, including, but not limited to:

| • |  | Implement strategic organic growth initiatives and identification and successful integration of acquisitions;

| • |  | Evolve enterprise systems, technology and processes with measurable impacts; and

| • |  | Ensure ICF has an appropriate depth of talent ready to succeed the top two levels of senior leaders.

In addition, Messrs. Wasson and Morgan have specific goals related to ESG factors, to enhance and communicate our commitment to a more sustainable planet and enhance the lives of our employees in the communities we serve.

The Committee approved the following results for the individual performance portion of the NEOs’ compensation as follows:

INDIVIDUAL PERFORMANCE FACTORS – RESULTS |
Executive |  | Target |  |  | Actual |
John Wasson |  |  | 20 | % |  |  | 15.3 | %

Long-Term Incentive Equity Awards

Equity Awards. The long-term incentive equity awards component of the Company’s compensation program is designed to:

| • |  | enhance the link between the creation of stockholder value and long-term executive incentive compensation;

| • |  | encourage participants to focus on long-term Company performance;

| • |  | provide an opportunity for increased equity ownership by executives;

| • |  | provide a retention tool for key talent; and

| • |  | maintain competitive levels of long-term incentive compensation.

In determining awards to the NEOs, the Committee considers current value and projected share usage. Equity awards vary among participants based on their positions within the Company, their individual contributions, and the value they have added to the organization.

|  | 58

##### Table of Contents

|  | EXECUTIVE COMPENSATION

The NEOs’ annual long-term equity award is divided evenly with 50% weight on RSUs and 50% weight on PSAs. RSUs are focused on executive retention with three-year time-based vesting requirements and are settled in shares. PSAs are tied to the Company’s compounded annual growth rate in adjusted EPS and the Company’s cumulative total stockholder return relative to its compensation peer group (“rTSR”) and are also settled in shares.

Performance Share Awards. The number of shares that the participant ultimately will receive in connection with a PSA is based on the Company’s performance during two (2) periods. The initial performance period (the “Initial Performance Period”) is two (2) years, from the beginning of year one to the end of the year two, and at the end of such period the PSA will be calculated based on Adjusted EPS (“PSA Adjusted EPS”). There will be no payout if PSA Adjusted EPS does not meet or exceed threshold performance.

Performance Level vs. Adjusted EPS Goal |  | % of Payout |
Maximum |  |  | 150 | %
Target |  |  | 100 | %
Threshold |  |  | 50 | %
<Threshold |  |  | 0 | %

The secondary performance period (the “Secondary Performance Period”) is three (3) years, from the beginning of year one to the end of year three, with the PSA further calculated and paid out at the end of such period based on rTSR multiplied by the Adjusted EPS payout calculation.

rTSR Performance Level vs. Compensation Peer Group |  | Modifier of Adjusted EPS Result |
Maximum – 75th percentile |  |  | 125 | %
Target – 50th percentile |  |  | 100 | %
Threshold – 25th percentile |  |  | 75 | %

The PSA shares are eligible to vest only following the expiration of the Secondary Performance Period. Actual shares vested will be based on the actual financial measures and rTSR achieved within a range between 37.5% and 187.5% of the target number of shares. Performance between threshold and maximum will be determined by straight line interpolation between the targeted amounts.

The number of RSUs and PSAs awarded to an individual participant is determined by:

| 1. | Dividing the target dollar value of the annual equity grant by two (2) to determine the amount to be granted as RSUs, with the other half to be delivered as PSAs.

| 2. | Dividing the resulting RSU and PSA grant target values by the average share price of ICF stock over the twenty (20) day period preceding the grant date to arrive at the number of RSUs and PSAs to be granted, rounding down to the nearest whole share. The Committee approves annual awards at a pre-determined quarterly meeting of the Committee, and such awards are effective at a pre-determined date.

2022 Long-Term Equity Grants. In 2022, we continued the use of RSUs and PSAs. The RSUs have a three-year vesting schedule. The PSAs are tied to the Company’s PSA Adjusted EPS and rTSR. The Initial Performance Period began on January 1, 2022 and will end on December 31, 2023 (two (2) years), and at the end of such period the percentage of PSAs available for vesting will be calculated based on PSA Adjusted EPS. The Secondary Performance Period began on January 1, 2022 and will end on December 31, 2024 (three (3) years), with the PSA vesting further modified at the end of such period based on rTSR. The shares underlying the PSAs will be eligible to vest only following the expiration of the Secondary Performance Period.

Following are the 2022 NEO long-term equity targets. The Committee approved changes for Messrs. Wasson, Morgan and Lee to bring total compensation closer to market median for their roles.

2022 EXECUTIVE LONG-TERM EQUITY TARGETS |
EXECUTIVE |  | 2021 EQUITY TARGET |  |  | 2022 EQUITY TARGET |

2022 Other Awards Granted. In 2022, two other awards were granted to two executives taking on new roles. A sign-on grant was provided to Mr. Broadus on March 20, 2022, in connection with his employment as CFO, and a special grant was provided to Mr. Lee on November 8, 2022, to recognize his acceptance of the new role of Chief Technology Executive. Both grants were standard RSU grants with normal vesting of 25% after the first year, 25% after the second year, and 50% after the third anniversary of the date of grant.

2021 Performance Share Awards. In 2021, we granted PSAs under our Performance Program, the vesting of which was tied in the Initial Performance Period to the PSA Adjusted EPS and, in the Secondary Performance Period, to the Company’s rTSR performance. The Initial Performance Period for these PSAs began on January 1, 2021, and ended on December 31, 2022.

In February 2023, the Committee met to review the Initial Performance Period EPS measurement and the proposed adjustments to reported EPS, for the purpose of considering the exclusion of several items from EPS and determining the PSA Adjusted EPS.

As a starting point, the Committee noted that the Company reported EPS of $3.38 for the fiscal year ended December 31, 2022. (See Annex B to this Proxy Statement). The Committee then reviewed and considered whether certain expenses should be excluded from the reported EPS. After discussion and deliberation, the Committee approved aggregate exclusions of approximately $29.0 million, or $1.11 per share, including the impact of taxes. The Committee also approved a negative adjustment in the amount of $0.01 to neutralize the positive impact of the ESAC acquisition, $0.09 per share to remove the positive impact of the SemanticsBits acquisition, and $0.03 to account for the positive impact of the Creative acquisition. The final adjustment was to add $0.06 to account for Blanton’s initial negative impact on Adjusted EPS for performance shares for the previously awarded 2021 grant.

The after-tax adjustments for the exclusions resulted in an adjustment to reported EPS of $1.04, or a PSA Adjusted EPS of $4.42 for purposes of determining calculations for the Initial Performance Period and for establishing the baseline EPS for the 2021 PSA grants. See attached Annex B to this Proxy Statement for a description of the GAAP reconciliation.

The Committee’s determination was between the Target and Maximum requirements, which were $4.30 and $4.63, respectively, and would generate a payout calculation of 117.3%, subject to the application of the Secondary Performance Period factor. The Secondary Performance Period began on January 1, 2021, and will end on December 31, 2023 (three (3) years). The PSAs are eligible to vest only following the expiration of the Secondary Performance Period.

2020 Performance Share Awards. In 2020, we granted PSAs under our Performance Program, the vesting of which was tied in the Initial Performance Period to the PSA Adjusted EPS and, in the Secondary Performance Period, to the Company’s rTSR performance. The Initial Performance Period for these PSAs began on January 1, 2020 and ended on December 31, 2021.

In February 2022, the Committee approved the Initial Performance Period EPS measurement and the adjustments to reported EPS, for the purpose of considering the exclusion of several items from EPS and determining the PSA Adjusted EPS. The Committee’s determination was between the Target and Maximum requirements, which were $4.16 and $4.49, respectively, and would generate a payout calculation of 116.9% subject to the application of the Secondary Performance Period factor. The Secondary Performance Period began on January 1, 2020 and ended on December 31, 2022 (three (3) years). The PSAs are eligible to vest only following the expiration of the Secondary Performance Period.

The Company engaged Aon to calculate its cumulative total stockholder return over the Performance Period relative to its Peer Group. It was measured by (a) the sum of (i) the Company’s Average Stock Price (for the 45 day trading period ending December 31, 2022), and (ii) the cumulative amount of dividends declared during the Performance Period, assuming dividend reinvestment on the ex-dividend date, divided by (B) the Company’s Average Stock Price at the beginning of the Performance Period (for the 45 day trading period ending December 31, 2019); provided, that for purposes of calculating rTSR percentile rank, the Company is excluded from the Peer Group. Aon calculated the Company’s total stockholder return at the 23rd percentile of the group resulting in a 75% rTSR vesting modifier to the PSA Adjusted EPS calculation of 116.9%, resulting in a total of approximately 87.6% of target shares vested. The Committee approved and certified the calculation, and the vested shares were released in January 2023.

2023 Base Salary. The Human Capital Committee annually reviews the salaries of our NEOs. In considering salary adjustments, the Committee takes into account: peer group market data, individual performance and changes in job responsibilities. The increase for Ms. Choate was made in consideration for her performance as well as moving her base salary closer to the market median. The increase for Mr. Lee was made in consideration for his promotion to Chief Technology Executive and his performance. The increases for the other NEOs were made primarily for consideration of performance. In February 2023, the Committee approved the following salaries:

ANNUAL BASE SALARY |
Executive |  | 2022 Base Salary |  |  | 2023 Base Salary |  |  | 2022 % Increase |
John Wasson |  | $ | 970,000 |  |  | $ | 1,008,800 |  |  |  | 4.0 | %
James Morgan |  | $ | 616,044 |  |  | $ | 640,685 |  |  |  | 4.0 | %
Barry Broadus |  | $ | 450,000 |  |  | $ | 468,000 |  |  |  | 4.0 | %
Anne Choate |  | $ | 475,175 |  |  | $ | 500,000 |  |  |  | 5.2 | %
Mark Lee |  | $ | 486,200 |  |  | $ | 550,000 |  |  |  | 13.1 | %

Annual Incentive Plan for 2023. Based on the same factors used to determine base salary, the Committee concluded

that target cash incentive awards as a percentage of base salary would increase for Messrs. Wasson, Morgan and Lee, to bring total compensation closer to market median for their roles:

ANNUAL INCENTIVE PLAN TARGETS |
Executive |  | 2022 Target |  |  | 2023 Target |
John Wasson |  |  | 115 | % |  |  | 125 | %
James Morgan |  |  | 70 | % |  |  | 80 | %
Barry Broadus |  |  | 70 | % |  |  | 70 | %
Anne Choate |  |  | 50 | % |  |  | 50 | %
Mark Lee |  |  | 50 | % |  |  | 60 | %

The Committee continued to employ a performance threshold for Gross Revenue of 80%, which allows for a 40% payout consistent with the 2022 Annual Incentive Plan. Performance will be measured on a straight-line interpolation between new threshold of 80% and original threshold of 90%, and any performance above 90% will be measured on the straight-line interpolation between 90% and 125%. The current performance threshold and payout factor for EPS will remain unchanged.

2023 Long-Term Equity Grants. In 2023, we will continue the award of RSUs and PSAs with equal weighting. The RSUs and PSAs will have the same three-year vesting schedules as in 2022. The PSAs will continue to be tied to the Company’s adjusted EPS and rTSR. The Initial Performance Period began on January 1, 2023 and will end on December 31, 2024 (two (2) years). At the end of such period the percentage of PSAs available for vesting will be calculated based on PSA Adjusted EPS. The Secondary Performance Period began on January 1, 2023 and will end on December 31, 2025 (three (3) years) with the PSA vesting further modified at the end of such period, based on rTSR. The shares underlying the PSAs will be eligible to vest only following the expiration of the Secondary Performance Period.

Following are the 2023 NEO equity targets which the Committee and Board approved in February 2023. Adjustments were made to move certain NEOs closer to the competitive 50th percentile for target total compensation:

2023 LONG-TERM EQUITY TARGETS |
EXECUTIVE |  |  | 2022 EQUITY TARGET |  |  |  | 2023 EQUITY TARGET |
John Wasson |  |  | 270 | % |  |  | 325 | %

| ● |  | We make matching contributions each pay period equal to 100% of an employee’s 401(k) contributions up to the first 3% of the employee’s compensation. We also make matching contributions equal to 50% of the employee’s 401(k) contributions up to the next 2% of the employee’s compensation.

| ● |  | We do not make matching contributions for employee 401(k) contributions in excess of 5% of the employee’s compensation.

Company contributions to this plan for our NEOs are included under the “All Other Compensation” column of the Summary Compensation Table below.

Perquisites. The Company does not provide any material perquisites or personal benefits to its NEOs.

Severance Benefits. As of December 31, 2022, the Company was a party to severance protection agreements with Messrs. Wasson, Morgan, Broadus and Lee and Ms. Choate that provide severance benefits in the event of a termination in connection with a change of control and in certain other situations. We believe these agreements serve to promote stability and continuity among our NEOs. The terms of these agreements and information regarding applicable payments under such agreements are provided under “Wasson Employment and Severance,” “Payments to Other NEOs Pursuant to Severance Letter Agreements,” and “Potential Payments Change of Control,” below.

Compensation Practices and Risk

The Committee annually considers, in establishing and reviewing the executive compensation program, whether the program encourages unnecessary or excessive risk taking. We do not believe the Company’s compensation policies and practices are reasonably likely to have a material adverse effect on the Company in connection with risk management practices and risk-taking incentives.

The Committee’s goal is to design and establish a compensation program to encourage prudent risk management and discourage inappropriate risk-taking by granting a diverse portfolio that rewards the creation of long-term stockholder value. To help achieve this goal, the Committee considers the risk profile of the primary compensation elements, including base salary, the Annual Incentive Plan and equity awards.

The Committee believes that the base salaries of the NEOs, being fixed in amount, do not encourage inappropriate risk-taking. Performance factors which serve as the basis for the Annual Incentive Plan of the Company’s NEOs may be adjusted each year to account for changes in our business and related risks. Also, a significant proportion of the NEOs compensation is in the form of equity awards with performance and retention features that extend over a period of years. These equity awards do not encourage unnecessary or excessive risk-taking because their ultimate value is tied to our stock price and other stockholder-aligned measures (i.e., adjusted EPS growth). The equity awards are subject to long-term vesting schedules so as to help ensure that the NEOs have significant value tied to long-term stock price performance. Specifically, all equity compensation is based either on performance over a three (3)-year period or vesting for a three (3)-year period. This encourages the NEOs to focus on long-term performance, as well as annual results, further reducing inappropriate risk-taking likely to produce only short-term benefits and allowing sufficient time for risk outcomes to emerge.

Additionally, awards under the 2018 Incentive Plan are subject to clawback provisions based on certain factors, as noted in the “Compensation Recoupment Policy” included in the Plan. In addition, Messrs. Morgan, Broadus and Lee and Ms. Choate are parties to severance agreements that provide for enhanced clawback rights. See “Payment to other NEOs Pursuant to Severance Letter Agreements--Clawback Events and Rights” in this Proxy Statement. On October 26, 2022, the SEC adopted Rule 10D-1 to the Exchange Act to implement the requirements of the Dodd-Frank Act. Rule 10D-1 directs the national securities exchanges and associations (including our own securities exchange, NASDAQ) to establish listing standards requiring each listed issuer to implement policies providing for, in the event of certain accounting restatements, the recovery of incentive-based compensation received by current or former executive officers to the extent such compensation was based on erroneously reported financial information. If Proposal 2 of this Proxy Statement is approved by our shareholders, the ICF 2018 Omnibus Incentive Plan will be amended and restated to, among other things, include updated compensation recovery provisions that coordinate with the requirements of Rule 10D-1, in the expectation that NASDAQ’s listing standards under Rule 10D-1 will become effective no later than November 2023. Additionally, once the final NASDAQ listing standards have been approved, the Company anticipates it will adjust its compensation recovery arrangements to further coordinate with Rule 10D-1, including through the adoption of a clawback policy for that purpose.

(1) | The annual base salary adjustments for our NEOs are made in March of each evaluation year and are effective immediately.

(2) | The amounts reported in the “Stock Awards” column (d) of the table above reflect the aggregate grant date fair value of RSUs and PSAs. These values have been determined under the principles used to calculate the grant date fair value of equity awards for purposes of the Company’s financial statements. For a discussion of the methodologies used to value the awards reported in the “Stock Awards” column (d), please see the discussion of stock awards contained in Note 15 – Accounting for Stock-Based Compensation in our consolidated financial statements included in our 2022 Form 10-K.

The grant date fair value of PSAs is calculated based upon the probable performance under the awards’ goal, which was target performance achievement. Assuming the target and maximum payout of the PSAs is achieved, the value of each NEO’s award as of the grant date is as follows:

Name |  | 2022 Grant Date Fair Value PSAs at Target Payout ($) (reflected in table) |  | 2022 Grant Date Fair Value PSAs at Maximum Payout ($)

Deferred Compensation Plan

We maintain a non-qualified deferred compensation plan (the “Deferred Compensation Plan”) for a select group of key management and highly compensated employees who have been designated as eligible to participate in the Deferred Compensation Plan by the Board or the Human Capital Committee.

The Deferred Compensation Plan allows participants to defer up to 80% of base salary and/or up to 100% of bonus and commissions. All amounts deferred are 100% vested. In addition, we may credit a participant’s Deferred Compensation Plan account with our contributions required under an employment agreement or any other agreement and/or with discretionary

contributions by us. The Company’s contributions are vested pursuant to the terms of any relevant agreement or, if none, on the anniversary of the date on which such contribution was credited to the participant’s account balance, in accordance with the following schedule; provided, however, that the participant must be in service to the Company as an employee on such anniversary to receive vesting credit:

Less than 1 year—0%

1 year but less than 2 years—33%

2 years but less than 3 years—67%

3 or more years—100%

One (1) of the NEOs participated in the Deferred Compensation Plan in 2022. None of our contributions were credited under the Deferred Compensation Plan for 2022. Deferred Compensation Plan accounts are deemed to be invested in one (1) or more investment options selected by each participant from investment options offered under the Deferred Compensation Plan.

Deferred Compensation Plan participants are entitled to receive distributions from their Deferred Compensation Plan accounts upon separation from service, death, disability and/or upon a

specified date. Subject to the provisions of Section 409A of the Code, Deferred Compensation Plan participants may elect to receive distributions from the Deferred Compensation Plan in single lump-sum payments or installment payments over a period of two (2) to five (5) years for deferrals to specified dates, or two (2) to fifteen (15) years for deferrals until death, disability or other separation from service. If no such election is made, a participant shall be deemed to have elected a lump-sum form of payment. The following table sets forth information, as of December 31, 2022, regarding contributions and balances of NEOs under the Deferred Compensation Plan:

Potential Payments upon Termination or Change of Control

We maintain severance, and/or change of control agreements with our NEOs. The following summaries describe and quantify the payments each NEO would receive if his or her employment with the Company were terminated or if we experienced a change of control and the NEO’s employment was terminated following the change of control. The summaries assume that the termination and/or change of control occurred on December 31, 2022, and that the relevant stock price is the closing market price for our common stock on NASDAQ on December 31, 2022, which was $99.05 per share.

The severance provisions of our agreements with our NEOs have a “double trigger” in relation to severance following a change of control. Our NEOs do not receive such severance and other benefits in connection with a change of control unless they are terminated without cause or resign for good reason within twelve (12) months following the change of control, except for Mr. Wasson, who has a twenty-four (24) month period.

In addition, the executives are entitled to accelerated vesting of restricted stock and other equity awards in accordance with their terms, although some are not payable until their original vesting dates.

Payment of these severance benefits is subject to the executive’s compliance following termination with certain covenants and requirements, such as confidentiality and non-solicitation of customers and employees, and receipt of customary releases.

All amounts and benefits under the agreements described below are to be paid in a manner and form that complies with Code Section 409A or an exception thereunder. The agreements also provide that in the event we determine that any payment,

distribution, or other action to or for the executive’s benefit would reasonably be expected to cause any loss of deductions under Code Section 280G, we have the authority to reduce any or all such payments, distributions or other actions to the extent reasonably necessary to avoid the imposition of such excise tax.

Wasson Severance Agreement

We do not have an employment agreement, as such, with Mr. Wasson, but we have entered into a revised Restated Severance Protection Agreement, described below.

Certain changes in Mr. Wasson’s severance arrangements became effective on October 1, 2019, when he became our Chief Executive Officer.

In general terms, under the revised agreement, in the event of an involuntary termination of Mr. Wasson upon death or disability, by the Company for Cause, or a voluntary termination by Mr. Wasson without Good Reason, he would not be entitled to severance, but would be entitled to his accrued compensation and, except in the case of a termination for Cause, a pro rata bonus for the portion of the year prior to the termination. In the event of a termination more than 24 months after a change of control by the Company without Cause or by Mr. Wasson for Good Reason, he would receive (a) his accrued compensation, (b) pro rata bonus, (c) 24 months of health and certain other benefits, and (d) two times the sum of his base salary plus target annual incentive plan bonus. In the event of a termination within 24 months after a change of control by the Company without Cause or by Mr. Wasson for Good Reason, he would receive (a) his accrued compensation, (b) pro rata bonus, (c) 36 months of health and certain other benefits, and (d) three times the sum of his base salary plus target annual incentive plan bonus.

|  | EXECUTIVE COMPENSATION

“Cause” for the termination of Mr. Wasson’s employment with the Company means any of the following: (a) any act that would constitute a material violation of the Company’s material written policies; (b) willfully or knowingly engaging in conduct (i) materially and demonstrably injurious to the Company, or (ii) causing a material and adverse reputational or financial harm to the Company; provided, however, that no act or failure to act, on Mr. Wasson’s part, shall be considered “willful” or “knowing” unless done, or omitted to be done, by Mr. Wasson not in good faith and without reasonable belief that his action or omission was in the best interest of the Company; (c) being indicted for, or if not indicted for, being charged with (i) a crime of embezzlement or a crime involving moral turpitude, (ii) a crime with respect to the Company involving a breach of trust or dishonesty or (iii) in either case, a plea of guilty or no contest to such a crime; (d) abuse of alcohol in the workplace, use of any illegal drug in the workplace or a presence under the influence of alcohol or illegal drugs in the workplace; (e) failure to comply in any material respect with applicable law; or (f) willful failure to follow the lawful directives of the Board.

“Good Reason” means the occurrence of any of the events or conditions described in clauses (a) through (e) below, without Mr. Wasson’s written consent:

(a) any (i) material adverse change in Mr. Wasson’s status, title, position or responsibilities (including reporting responsibilities) from Mr. Wasson’s status, title, position or responsibilities, (ii) assignment to Mr. Wasson of duties or responsibilities which are inconsistent with Mr. Wasson’s status, title, position or responsibilities, or (iii) the failure of Mr. Wasson to continue to serve as an executive officer of a public company, in each case except in connection with the termination of Mr. Wasson’s employment due to disability, Cause, as a result of Mr. Wasson’s death or by Mr. Wasson other than for Good Reason;

(b) a reduction in Mr. Wasson’s base salary or any failure to pay Mr. Wasson any cash compensation to which Mr. Wasson is entitled within fifteen (15) days after the date when due;

(c) the imposition of a requirement that Mr. Wasson be based (i) at any place outside a fifty (50) mile radius from

Mr. Wasson’s principal place of employment or (ii) at any location other than our corporate headquarters, except, in each case, for reasonably required travel on our business which is not materially greater in frequency or duration than prior to the imposition of the requirement;

(d) any material breach by the Company of any provision of the agreement; or

(e) the failure of the Company to obtain, as contemplated by the agreement, an agreement, reasonably satisfactory to Mr. Wasson, from any successor entity to assume and agree to perform the agreement; provided, that Mr. Wasson (i) provides us with written notice of the condition giving rise to the Good Reason within ninety (90) days of Mr. Wasson’s knowledge of the initial existence of the condition, (ii) provides us with the opportunity to cure within thirty (30) days of Mr. Wasson’s written notice, and (iii) if we do not cure the condition within such thirty (30) day cure period, terminates employment within two (2) years after the date of the initial existence of the condition. A termination will not be deemed to be for Good Reason if Mr. Wasson agrees in writing that a particular condition that would otherwise constitute Good Reason does not constitute Good Reason.

Under the terms of Mr. Wasson’s PSA agreements, upon termination without Cause or for Good Reason, all performance shares will vest and be delivered at the end of the performance period based on actual performance. In the event of a termination without Cause or for Good Reason within two years after a change of control, the PSA’s will fully vest as of the date of termination and be payable, based on attainment of target EPS performance and actual rTSR performance, calculated to the date of termination, within thirty days after the termination.

The payments that would have been made to Mr. Wasson, pursuant to his agreements, other than following a change of control, are in the table below. Payments are calculated using the base salary and target bonus in effect as of a termination of employment on December 31, 2022. Severance costs are subject to change as base salary and target bonus amounts change over time. See discussions of 2022 Base Salary and Target bonuses on page 56.

Payments to other NEOs Pursuant to Severance Letter Agreements

On February 27, 2020, we entered into a severance letter agreement with Mr. Morgan, replacing a prior arrangement. On January 6, 2022, we entered into a new agreement with Mr. Broadus in connection with his appointment to serve as Senior Vice President and CFO. On November 21, 2021, we entered into a severance letter agreement with Mr. Lee, Executive Vice President, Chief Technology Executive, and Anne Choate, Executive Vice President and Group Leader. The terms of these severance letter agreements (the “Agreements”) are the same.

Under the Agreements, severance is available in the event (i) the executive’s employment is involuntarily terminated without Cause (as defined in our most current omnibus incentive plan (the “Plan”)) before a Change of Control (as defined in the Plan by reference to Code Section 409A), or (ii) there is a Change of Control and within twelve months thereafter the executive’s employment is involuntarily terminated without Cause or terminated by the executive for Good Reason (each as defined in the Plan). The Agreements also provide us with certain “clawback” rights as described below.

Not for Cause Termination Other than Following a Change of Control

In the event we involuntarily terminate an executive’s employment for a reason other than Cause, death, disability or retirement, or longer than twelve months after a Change of Control, the executive is entitled to receive the following benefits:

| ● |  | twelve months of severance pay calculated based on the executive’s base salary at the time of termination, payable commencing within 60 days after termination and in accordance with the Company’s normal payroll practices;

| ● |  | the sum of (i) the executive’s target bonus for the year in which the executive’s employment was involuntarily terminated, plus (ii) a prorated share of the executive’s target bonus for the year in which the executive’s employment was involuntarily terminated based on the number of full months in the final calendar year in which the executive was employed, payable in a lump sum within 90 days after termination;

| ● |  | the option to continue the executive’s health insurance coverage in accordance with COBRA, with the monthly COBRA premiums for the executive and dependents during the severance payment period being equal to the amount the executive would have paid each month for such group health plan coverage had the executive remained actively employed, which premiums will be payable by the executive, such benefit to cease if the executive becomes employed and is eligible to receive group health plan coverage from the new employer; and

| ● |  | the option to participate in a six-month executive career transition service.

Under the terms of the NEO PSA agreements, upon termination without cause or for good reason, a prorated number of the PSAs will vest according to the actual EPS and rTSR performance during the entire performance period, prorated based on the number of months of the performance period prior to the date of termination, and be payable at the end of the performance period.

Termination without Cause or for Good Reason Following a Change of Control

In the event that, within twelve months after a Change of Control, the executive’s employment is terminated without Cause by the Company or by the executive for Good Reason, the executive is entitled to receive the following:

| ● |  | twenty-four months of severance pay calculated based on the executive’s base salary at the time of termination, payable commencing within 60 days after termination and in accordance with the Company’s normal payroll practices;

| ● |  | the executive’s target bonus for the year in which the executive’s employment was involuntarily terminated, payable in a lump sum within 90 days after termination;

| ● |  | the option to continue the executive’s health insurance coverage in accordance with the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”), with the monthly COBRA premiums for the executive and dependents during the severance payment period being equal to the amount the executive would have paid each month for such group health plan coverage had the executive remained actively employed, which premiums will be payable by the executive, such benefit to cease if

##### Table of Contents

|  | EXECUTIVE COMPENSATION

|  | the executive becomes employed and is eligible to receive group health plan coverage from a new employer; and

| ● |  | the option to participate in a six-month executive career transition service.

Under the Agreements, “Good Reason” means if, within the twelve months following a Change of Control, any of the following events occur to which the executive has not consented in writing: (i) a material reduction of the nature and scope of the authority, functions or duties that were assigned to the executive immediately prior to the Change of Control; (ii) a material reduction in the compensation the executive was eligible to receive (including applicable bonus plans) immediately prior to the Change of Control; (iii) we relocate the executive’s primary office and work location 50 miles or more away from the primary office and work location at which the executive was situated immediately prior to the Change of Control; or (iv) the entity effectuating the Change of Control fails to adopt the Agreement.

The vesting of any equity awards will be in accordance with the Plan and the applicable award agreement. Other than PSAs, equity grants will vest on an accelerated basis following a change in control if the executive is terminated other than for cause within two (2) years following the Change of Control.

In the event of a termination without Cause or for Good Reason within two years after a change of control, the PSAs will fully vest as of the date of termination and be payable, based on attainment of target EPS performance and actual rTSR performance during the period prior to the date of termination, within thirty days after the termination.

Clawback Events and Rights

The Agreements strengthen and broaden the Company’s “clawback” rights under our 2018 Incentive Plan. The Agreements provide that, except following a Change of Control, we have “clawback” rights with respect to “Excess Incentive Awards” arising from “Clawback Events” as defined in the Agreements. Except in situations involving fraud (as to which the statute of limitations will apply), the Committee may, within three years after the later to occur of a Clawback Event or harm to us, determine and recommend to the Board (acting in its sole discretion, but in good faith) that we recover (including, without limitation, through forfeiture) all or a portion of any incentive compensation (including short-term incentive awards or bonuses and long-term (equity) incentive awards) that was granted after the date of the Agreement based wholly or in part on a financial reporting, stock price or similar shareholder return measure under an incentive compensation plan or other incentive compensation arrangement with respect to any of our fiscal year(s) that were negatively affected by such events or matters.

Following and based upon the recommendation of the Human Capital Committee, the independent members of the Board will review the recommendation and determine whether to direct the Company to assess a recovery from the executive and the amount of recovery to be assessed as an Excess Incentive Award (as defined below). In no event will the amount to be

recovered from the executive by the Company in such situations be less than the amount required to be repaid or recovered as a matter of law.

The Board, acting through the independent directors, will determine whether we will recover from the executive such amounts by: (i) seeking repayment, (ii) forfeiting or reducing (subject to applicable law and the terms and conditions of the applicable plan, program or arrangement) the amount that would otherwise be payable to the executive under any compensatory plan, program, or arrangement maintained by us, (iii) withholding payment of future increases in the executive’s compensation (including the payment of any discretionary bonus amount) or grants of compensatory awards that would otherwise have been made in accordance with our otherwise applicable compensation practices, or (iv) any combination of the foregoing. If so determined by the Board, the executive is required to repay the Excess Incentive Award to us.

The Agreements define a “Clawback Event” to include:

| ● |  | the executive’s acts or omissions (whether or not constituting misconduct) that are a significant contributing factor to the Company having to restate our financial statements;

| ● |  | the fact that our financial results, as used to determine the executive’s incentive compensation, are found to reflect a material error or otherwise be materially inaccurate, whether or not the executive was responsible for, or the executive’s actions were a significant contributing factor with respect to, the inaccuracy; and/or

| ● |  | the executive engaged in conduct that is or could have been a basis for termination for Cause, and which causes a material and adverse reputational or other financial harm to us.

An “Excess Incentive Award” is the amount of the clawback determined by the Board of Directors in accordance with the Agreements. For illustrative purposes:

in the case of a restatement, the Excess Incentive Award would generally be no more than the positive difference, if any, between the short-term incentive awards or bonuses paid to the executive and the amounts(s) of such payments that would have been payable to the executive had the amount(s) of the award(s) been calculated based on our financial statements, as restated, plus an amount reflecting the effect of the restatement on long-term (equity) incentive awards that were granted after the date of the Agreement.

On October 26, 2022, the SEC adopted Rule 10D-1 to the Exchange Act to implement the requirements of the Dodd-Frank Act. Rule 10D-1 directs the national securities exchanges and associations (including our own securities exchange, NASDAQ) to establish listing standards requiring each listed issuer to implement policies providing for, in the event of certain accounting restatements, the recovery of incentive-based compensation received by current or former executive officers to the extent such compensation was based on erroneously reported financial

information. If Proposal 2 of this Proxy Statement is approved by our shareholders, the ICF 2018 Omnibus Incentive Plan will be amended and restated to, among other things, include updated compensation recovery provisions that coordinate with the requirements of Rule 10D-1, in the expectation that NASDAQ’s listing standards under Rule 10D-1 will become effective no later than November 2023. Additionally, once the final NASDAQ listing standards have been approved, the Company anticipates it will adjust its compensation recovery arrangements to further coordinate with Rule 10D-1, including through the adoption of a clawback policy for that purpose.

Ms. Welsh’s departure was not due to any disagreement or dispute with the Company and she was separated without cause. Ms. Welsh continued to serve as Chief Financial Officer through the filing of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021. She continued to be employed as an executive until April 8, 2022, to support the Company during the transition of her responsibilities to her successor.

Per the terms of her Separation Agreement and Release of Claims disclosed in the Form 8-K filed on January 20, 2022, Ms. Welsh received the following:

| ● |  | Twelve months of severance pay based upon the Executive’s base salary as of the Transition Date, less taxes and other required withholding, such severance pay to be paid in bi-weekly equal installments;

|  | CEO PAY RATIO

CEO PAY RATIO

Following is a reasonable estimate, prepared under applicable SEC rules, of the ratio of the annual total compensation of our CEO, John Wasson, to the median of the annual total compensation of our other employees.

For the fiscal year ended on December 31, 2022, we determined the median employee’s total compensation, including any perquisites and other benefits, in the same manner that we determine the total compensation of our named executive officers for purposes of the Summary Compensation Table disclosed in the Compensation Discussion & Analysis section of this Proxy Statement. The median employee’s annual 2022 total compensation was $79,014. The annual total compensation of our CEO, as reported in the Summary Compensation Table in this proxy statement, was $4,848,381. Based on this information for 2022, we reasonably estimate that the ratio of our CEO’s annual total compensation to the annual total compensation of our median employee was 61:1. Our pay ratio estimate has been calculated in a manner consistent with Item 402(u) of Regulation S-K.

Median of the Annual Total Compensation of All Employees (except CEO) |  | Annual Total Compensation of CEO |  | Ratio of CEO Pay to Median Employee Pay
(A) |  | (B) |  | (C) = (B)/(A)
$79,014 |  | $ 4,848,381 |  | 61

(A) | Median employee’s compensation plus Company’s 401(k) contribution is used for the calculation.

(B) | Data from the “Total” Column from the Summary Compensation Table disclosed for 2022 in this Proxy Statement.

To identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee, the methodology and the material assumptions, adjustments, and estimates we used are set out below.

We determined that, as of December 31, 2022, our employee population consisted of 9,008 individuals (including full-time and part-time employees, other than the CEO). Of these individuals, 8,072 were located in the U.S. and U.S. territories, and 936 were located in 14 other countries around the world.

The scale of our operations in many of these foreign countries is smaller, and we employ less than 30 employees in 10 of these 14 countries.

We chose to exclude all 91 of our employees in the 8 countries as follows:

| ● |  | Cameroon: 6 employees

| ● |  | China: 8 employees

| ● |  | Democratic Republic of the Congo: 26 employees

| ● |  | Germany: 1 employe

| ● |  | Kenya: 16 employees

| ● |  | Liberia: 8 employees

| ● |  | Madagascar: 5 employees

| ● |  | Mali: 8 employees

| ● |  | Nepal: 9 employees

| ● |  | Spain: 4 employees

Additionally, we excluded 131 employees that worked zero (0) hours during 2022 and therefore had $0 earnings. This includes flexible, part-time employees and employees on leave of absence.

In total, we excluded 2.46% of our workforce from the identification of the “median employee”, as permitted by SEC rules.

Our population, after taking into consideration the permitted adjustments described above, consisted of 8,786 employees. This includes employees who were hired in 2022 but did not work for us for the entire twelve-month period. Our adjusted employee population consisted of 7,946 employees in the U.S. and 840 international employees located collectively in Canada (82), Belgium (212), the United Kingdom (323) and India (223).

We identified our median employee based on the total taxable earnings paid during the twelve-month period ended December 31, 2022. For purposes of determining the total compensation actually paid, we included: the amount of base salary (or, in the case of hourly workers, base wages including overtime pay) the employee received during the twelve months ended December 31, 2022, and the amount of any cash incentives paid to the employee in such period, as reflected in our payroll records. We did not annualize the total cash compensation of any permanent employee employed for less than the full year.

Except as described in this section, we did not rely on any material assumptions, adjustments (e.g. the cost of living adjustments) or estimates (e.g. statistical sampling) to identify our median employee or determine annual total compensation or any elements of annual total compensation for our median employee or our CEO.

For purposes of identifying the median employee, we applied the average of 12 exchange rates we used for financial statement conversion purposes for the period of January 2022 through December 2022, which are:

| - | 1 CAD = 0.770931 USD

| - | 1 EUR = 1.057393 USD

| - | 1 GBP = 1.245828 USD

| - | 1 INR = 0.012795 USD

The SEC’s pay ratio disclosure rules provide reporting companies with a great deal of flexibility in determining the methodology used to identify the median employee and the pay ratio. Our methodology may differ materially from the methodology used by other companies to prepare their pay ratio disclosures. In addition, the percentage of employees outside of the United States may vary substantially from company to company. Factors such as these may contribute to a lack of comparability between our pay ratio and the pay ratio reported by other companies, including those within our sector.

The following disclosures are being provided in accordance with final rules adopted by the SEC, on August 2, 2022, pursuant to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010. Certain measures disclosed in the table below, including “Compensation Actually Paid,” are calculated in accordance with those rules. However, these rules were issued subsequent to the Human Capital Committee’s executive compensation determinations for 2022. Accordingly, the Human Capital Committee did not necessarily consider these measures (except with respect to

STOCKHOLDERS’ PROPOSALS FOR THE 2024 ANNUAL MEETING

Under applicable SEC rules, any stockholder who intends to present a proposal at the 2024 annual meeting of stockholders and who wishes to have the proposal included in our proxy statement and form of proxy for that meeting must deliver the proposal to us at our executive offices no later than December 23, 2023, or, if next year’s annual meeting of stockholders is held on a date more than 30 calendar days from June 1, 2024, a stockholder proposal must be received a reasonable time before we begin to post, print and mail our proxy materials for such annual meeting of stockholders. All stockholder proposals must comply with all applicable rules and regulations adopted by the SEC.

The Company’s Bylaws provide that, in order for a stockholder to make nominations for the election of directors or proposals for business to be brought before the annual meeting of stockholders, a stockholder must deliver notice of such nominations and/or proposals to the Corporate Secretary no earlier than the close of business on the 120th day, and not later than the close of business on the 90th day, prior to the first anniversary of the preceding year’s annual meeting of stockholders (for next year’s 2024 annual meeting of stockholders, these dates would be February 2, 2024 and March 3, 2024, respectively). However, if the annual meeting of stockholders is more than 30 days before or more than 60 days after such anniversary date, the notice must be received not earlier than the close of business on the 120th day prior to the date of such annual meeting of stockholders and not later than the close of business on the later of the 90th day prior to the date of such annual meeting of stockholders. Further, if the date of the annual meeting of stockholders is more than 30 days before or more than 60 days after such anniversary date, and the first public announcement of the date of such annual meeting of stockholders is less than 100 days prior to the annual meeting date, notice must be delivered not later than the close of business on the 10th day following the public announcement date. A copy of the Bylaws may be obtained from the Company by writing to ICF International, Inc., 1902 Reston Metro Plaza, Reston, Virginia, 20190, Attention: Corporate Secretary. In addition to the timing requirements set forth above, any stockholder nominations for the election of directors or proposals for business must comply with all other requirements set forth in the Company’s Bylaws.

In addition to complying with the procedures described above, stockholders who intend to solicit proxies in support of a director nominee other than the Company’s nominees for consideration by the stockholders at the Company’s 2024 annual meeting of stockholders must also comply with the SEC’s “universal proxy card” rules under Rule 14a-19 of the Exchange Act (“Rule 14a-19”).

We will pay all expenses in connection with the solicitation of the proxies. In addition to solicitation by mail, our directors, officers and employees may solicit proxies by telephone, electronically, in writing or in person, without receiving any extra compensation for such activities. The Company has engaged Alliance Advisors, LLC, a proxy soliciting firm, to assist in the solicitation of proxies and provide related advice and informational support, for a services fee and the reimbursement of customary disbursements, which are not expected to exceed $27,000 in the aggregate. We also will reimburse brokers and nominees who hold shares in their names for expenses they incur to furnish proxy materials to the beneficial owners of such shares.

Any stockholder who has not received a copy of the 2022 Form 10-K may obtain a copy by writing to the Corporate Secretary of the Company. The 2022 Form 10-K is not to be treated as part of the proxy solicitation material or as having been incorporated by reference into this Proxy Statement.

2022 PSA ADJUSTED EPS - GAAP RECONCILIATION

In connection with PSAs, upon completion of an Initial Performance Period, the 2010 Incentive Plan and the 2018 Incentive Plan as the case may be, and the Performance Program require that the Human Capital Committee (i) reviews the performance of the Company and propose adjustments to the reported EPS; and (ii) determines the PSA Adjusted EPS in accordance with the PSA Agreement and our 2010 Incentive Plan and the 2018 Incentive Plan as the case may be, which may exclude certain specified items. These exclusions are intended to ensure that the participants are compensated for the Company’s performance and are neither penalized nor rewarded for certain categories of specified adjustments.

For purposes of calculating the PSA Adjusted EPS for the PSAs granted in 2022 and 2021, the Human Capital Committee began with the Company’s reported diluted EPS of $3.38 and $3.72 for fiscal year 2022 and 2021, respectively, and excluded categories of items and amounts to arrive at the PSA Adjusted EPS of $4.42 and $4.27, respectively. Since PSA Adjusted EPS is a Non-GAAP measure, see the reconciliation of this Non-GAAP measure below:

In addition, except to the extent permitted by Code Section 409A, no extension of the exercise period fixed on the Grant Date of an Option shall be permitted. Notwithstanding the foregoing, for Nonqualified Stock Options granted to Participants outside the United States, the Committee may provide for a longer term to accommodate regulations in non-U.S. jurisdictions that require a minimum exercise or vesting period following a Participant’s death to achieve favorable tax results or comply with local law.

6.5 Minimum Vesting Period and Exercise of Options. Options granted under this ARTICLE 6 shall be exercisable at such times and be subject to such restrictions and conditions as the Committee shall in each instance approve, which terms and restrictions need not be the same for each grant or for each Participant; provided, however, that Options granted to Participants shall become vested and exercisable no earlier than one (1) year after the Grant Date except as otherwise provided in Section 4.4.

6.6 Payment. Options granted under this ARTICLE 6 shall be exercised by the delivery of a notice of exercise to the Company or an agent designated by the Company in a form specified or accepted by the Committee, or by complying with any alternative procedures which may be authorized by the Committee, setting forth the number of Shares with respect to which the Option is to be exercised, accompanied by full payment for the Shares. A condition of the issuance of the Shares as to which an Option shall be exercised shall be the payment of the Option Price. The Option Price of any exercised Option shall be payable to the Company in accordance with one of the following methods:

| (a) | In cash or its equivalent;

| (b) | By tendering (either by actual delivery or attestation) previously acquired Shares having an aggregate Fair Market Value at the time of exercise equal to the Option Price (provided that such Shares are not the subject of any pledge or other security interest);

| (c) | By a cashless (broker-assisted) exercise;

| (d) | By any combination of (a), (b), and (c); or

| (e) | Any other method approved or accepted by the Committee in its sole discretion.

Subject to any governing rules or regulations, as soon as practicable after receipt of written notification of exercise and full payment (including satisfaction of any applicable tax withholding), the Company shall deliver to the Participant evidence of book entry Shares, or upon the Participant’s request, Share certificates in an appropriate amount based upon the number of Shares purchased under the Option(s). Unless otherwise determined by the Committee, all payments under all of the methods indicated above shall be paid in United States dollars or Shares, as applicable.

6.7 Termination of Employment or Service. Each Participant’s Award Agreement shall set forth the extent to which the Participant shall have the right to exercise the Option following termination of the Participant’s employment or provision of services to the Company or any Affiliate or Subsidiary, as the case may be.

Agreement entered into with each Participant, need not be uniform among all Options issued pursuant to this ARTICLE 6, and may reflect distinctions based on the reasons for termination.

| (b) | Eligible Employees. ISOs may be granted solely to eligible Employees of the Company, Parent Corporation, or ISO Subsidiary (as permitted under Code Sections 422 and 424).

| (c) | Specified as an ISO. The Award Agreement evidencing the grant of an ISO shall specify that such grant is intended to be an ISO.

| (d) | Option Price. The Option Price of an ISO granted under the Plan shall be determined by the Committee in its sole discretion and shall be specified in the Award Agreement; provided, however, the Option Price must at least equal one hundred percent (100%) of the Fair Market Value of a Share as of the ISO’s Grant Date (in the case of 10% Owners, the Option Price may not be less than one hundred ten percent (110%) of such Fair Market Value).

| (e) | Right to Exercise. Any ISO granted to a Participant under the Plan shall be exercisable during his or her lifetime solely by such Participant.

| (f) | Exercise Period. The period during which a Participant may exercise an ISO shall not exceed ten (10) years (five (5) years in the case of a Participant who is a 10% Owner) from the Grant Date.

| (g) | Termination of Employment. In the event a Participant terminates employment due to death or disability, as defined under Code Section 22(e)(3), the Participant (or his or her beneficiary, in the case of death) shall have the right to exercise the Participant’s ISO Award during the period specified in the applicable Award Agreement solely to the extent the Participant had the right to exercise the ISO on the date of his or her death or disability, as applicable; provided, however that such period may not exceed one (1) year from the date of such termination of employment or, if shorter, the remaining term of the ISO.

| (i) | Duration of Plan. No Incentive Stock Options may be granted more than ten (10) years after the Effective Date.

| (j) | Notification of Disqualifying Disposition. If any Participant shall make any disposition of Shares issued pursuant to the exercise of an ISO, such Participant shall notify the Company of such disposition within thirty (30) days thereof.

6.9 No Deferral Feature. Except to the extent permitted under Code Section 409A, no NQSO or ISO shall contain any feature for the deferral of compensation (other than the deferral of recognition of income until the exercise of a NQSO).

The Committee may establish such procedures as it deems appropriate for a Participant to designate a beneficiary to whom any amounts payable or Shares deliverable in the event of, or following, the Participant’s death may be provided.

11.2 Committee Action. Except as provided in Section 6.8(k), the Committee may, in its discretion, determine that notwithstanding Section 11.1, any or all Awards shall be transferable to and exercisable by such transferees, and be subject to such terms and conditions as the Committee may deem appropriate; provided, however, no Award may be transferred for value without stockholder approval.

11.3 Restrictions on Share Transferability. The Committee may impose such restrictions on any Shares acquired by a Participant under the Plan as it may deem advisable, including, without limitation, minimum holding period requirements, restrictions under applicable federal securities laws, under the requirements of any stock exchange or market upon which such Shares are then listed or traded, or under any blue sky or state securities laws applicable to such Shares.

Each such designation shall revoke all prior designations by the same Participant, shall be in a form prescribed by the Committee, and will be effective only when filed by the Participant in writing with the Company during the Participant’s lifetime. In the absence of any such beneficiary designation, benefits remaining unpaid or rights remaining unexercised at the Participant’s death shall be paid to or exercised by the Participant’s executor, administrator, or legal representative.

ARTICLE 16

Rights of Participants

16.1 Employment. Nothing in this Plan or an Award Agreement shall: (a) interfere with or limit in any way the right of the Company, its Affiliates, and/or its Subsidiaries to terminate any Participant’s employment or service on the Board or to the Company at any time or for any reason not prohibited by law, or (b) confer upon any Participant any right to continue his or her employment or service as a Director for any specified period of time. Neither an Award nor any benefits arising under this Plan shall constitute an employment contract with the Company or any Affiliate or Subsidiary and, accordingly, subject to ARTICLES 3 and 18, this Plan and the benefits hereunder may be terminated at any time in the sole and exclusive discretion of the Committee without giving rise to any liability on the part of the Company, its Affiliates, and/or its Subsidiaries.

ARTICLE 17

17.1 Change of Control of the Company. Notwithstanding any other provision of this Plan to the contrary, the provisions of this ARTICLE 17 shall apply in the event of a Change of Control, unless otherwise determined by the Committee in connection with the grant of an Award as reflected in the applicable Award Agreement.

##### Table of Contents

|  | EXHIBIT A

| (a) | Outstanding Options and SARs Exchanged for Replacement Awards. Upon a Change of Control, if an Award meeting the requirements of Section 17.2 (a “Replacement Award”) is provided to a Participant to replace the Participant’s then-outstanding Options or Stock Appreciation Rights (the “Replaced Award”), then the Replaced Award shall be deemed cancelled and shall have no further force or effect and the Company shall have no further obligation with respect to the Replaced Award.

| (b) | Outstanding Options and SARs Not Exchanged for Replacement Awards. Upon a Change of Control, to the extent a Participant’s then-outstanding Options and Stock Appreciation Rights are not exchanged for Replacement Awards as provided for in Section 17.1(a), then such Options and Stock Appreciation Rights shall, subject to Section 17.3, continue to vest and become exercisable as set forth in the applicable Award Agreement.

| (c) | Service-Based Outstanding Awards Other Than Options and SARs. Unless otherwise provided in an Award Agreement, upon a Change of Control, all then-outstanding Awards, other than Options and SARs, that are not vested and as to which vesting depends solely on the satisfaction of a service obligation by a Participant to the Company, Subsidiary, or Affiliate shall, subject to Section 17.3, continue to vest and be subject to the restrictions related to the vesting or transferability of such Awards.

| (d) | Other Awards. Upon a Change of Control, the treatment of then-outstanding Awards not subject to subparagraphs (a), (b), or (c) above shall be determined by the terms and conditions set forth in the applicable Award Agreement.

| (e) | Committee Discretion Regarding Treatment of Awards Not Exchanged for Replacement Awards. Unless otherwise provided in an Award Agreement, except to the extent that a Replacement Award is provided to the Participant, the Committee may, in its sole discretion, (i) determine that any or all outstanding Awards granted under the Plan, whether or not exercisable, will be canceled and terminated and that in connection with such cancellation and termination the holder of such Award may receive for each Share subject to such Awards a cash payment (or the delivery of Shares, other securities or a combination of cash, Shares and securities equivalent to such cash payment) equal to the difference, if any, between the consideration received by stockholders of the Company in respect of a Share in connection with such transaction and the purchase price per Share, if any, under the Award multiplied by the number of Shares subject to such Award; provided that if such product is zero (0) or less or to the extent that the Award is not then exercisable, the Awards will be canceled and terminated without payment therefor; or (ii) provide that the period to exercise Options or Stock Appreciation Rights granted under the Plan shall be extended (but not beyond the expiration date of such Option or Stock Appreciation Right).

17.2 Replacement Awards. An Award shall qualify as a Replacement Award if: (a) it has a value at least equal to the value of the Replaced Award as determined by the Committee in its sole discretion; (b) it relates to publicly traded equity securities of the Company or its successor in the Change of Control or another entity that is affiliated with the Company or its successor following the Change of Control; and (c) its other terms and

##### Table of Contents

|  | EXHIBIT A

conditions are not less favorable to the Participant than the terms and conditions of the Replaced Award (including the provisions that would apply in the event of a subsequent Change of Control). Without limiting the generality of the foregoing, the Replacement Award may take the form of a continuation of the Replaced Award if the requirements of the preceding sentence are satisfied. The determination of whether the conditions of this Section 17.2 are satisfied shall be made by the Committee, as constituted immediately before the Change of Control, in its sole discretion.

17.3 Termination of Service.

| (a) | Nonemployee Directors. Upon a termination of directorship of a Nonemployee Director Participant occurring in connection with or during the period of two (2) years after such Change of Control, other than for Cause, all Awards described in Section 17.1(a), (b) and (c) above held by the Nonemployee Director Participant shall become fully vested and (if applicable) exercisable and free of restrictions.

| (b) | Employees. Upon a Termination of Employment of an Employee Participant in connection with or during the period of two (2) years after such Change of Control, either by the Company without Cause, or by the Employee Participant who terminates employment as a result of:

| (i) | a material reduction in the Employee’s authority duties or responsibilities;

| (ii) | the Employee’s relocation by the Company of more than fifty (50) miles from the Employee’s then current work location;

| (iii) | a reduction in the rate of Employee’s then annual base salary or target incentive compensation; or

| (iv) | failure of the surviving company to assume the Employee’s employment agreement or other applicable agreement relating to Employee’s employment,

then the Employee Participant’s Awards described in Section 17.1(a), (b) and (c) above shall become fully vested, exercisable, and free of restrictions.

17.4 Retirement. The Committee may provide special vesting and/or payment provisions in the case of a Participant’s Retirement (including retirement not as otherwise defined herein), which provisions will be set forth in the Participant’s Award Agreement. Such provisions may be set forth in the original Award Agreement or may be added by amendment, with the Participant’s consent, at any time.

ARTICLE 18

Amendment and Termination

18.1 Amendment and Termination of the Plan and Award Agreements.

| (a) | Subject to subparagraphs (b) and (c) of this Section 18.1 and Section 18.3 of the Plan, the Board may at any time terminate the Plan or an outstanding Award Agreement and the Committee may, at any time and from time to time, amend the Plan or an outstanding Award Agreement.

##### Table of Contents

|  | EXHIBIT A

| (b) | Except in connection with a Change of Control or a corporate transaction involving the Company (including, without limitation, any stock dividend, stock split, extraordinary cash dividend, recapitalization, reorganization, merger, consolidation, split-up, spin-off, combination, or exchange of shares), without stockholder approval (i) the terms of an outstanding Award may not be amended to reduce the Option Price of outstanding Options or to reduce the Grant Price of outstanding SARs, or (ii) no outstanding Options or SARs may be cancelled in exchange for cash, other Awards, or Options or SARs with an Option Price or Grant Price, as applicable, that is less than the Option Price of the cancelled Options or the Grant Price of the cancelled SARs.

| (c) | Notwithstanding the foregoing, no amendment of this Plan shall be made without stockholder approval if stockholder approval is required pursuant to rules promulgated by any stock exchange or quotation system on which Shares are listed or quoted or by applicable U.S. state corporate laws or regulations, applicable U.S. federal laws or regulations, and the applicable laws of any foreign country or jurisdiction where Awards are, or will be, granted under the Plan.

18.2 Adjustment of Awards Upon the Occurrence of Certain Unusual or Nonrecurring Events. Subject to Section 12.3, the Committee may make adjustments in the terms and conditions of, and the criteria included in, Awards in recognition of unusual or nonrecurring events (including, without limitation, the events described in Section 4.3 hereof) affecting the Company or the financial statements of the Company or of changes in applicable laws, regulations, or accounting principles, whenever the Committee determines that such adjustments are appropriate in order to prevent unintended dilution or enlargement of the benefits or potential benefits intended to be made available under this Plan. The determination of the Committee as to the foregoing adjustments, if any, shall be conclusive and binding on Participants under this Plan. By accepting an Award under this Plan, a Participant agrees to any adjustment to the Award made pursuant to this Section 18.2 without further consideration or action.

18.3 Awards Previously Granted. Notwithstanding any other provision of this Plan to the contrary, other than Sections 18.2, 18.4, or 21.14, no termination or amendment of this Plan or an Award Agreement shall adversely affect in any material way any Award previously granted under this Plan, without the written consent of the Participant holding such Award.

18.4 Amendment to Conform to Law. Notwithstanding any other provision of this Plan to the contrary, the Committee may amend the Plan or an Award Agreement, to take effect retroactively or otherwise, as deemed necessary or advisable for the purpose of conforming the Plan or an Award Agreement to any present or future law relating to plans of this or similar nature, and to the administrative regulations and rulings promulgated thereunder. By accepting an Award under this Plan, a Participant agrees to any amendment made pursuant to this Section 18.4 to any Award granted under the Plan without further consideration or action.

ARTICLE 19

##### Table of Contents

|  | EXHIBIT A

Company, the minimum statutory amount to satisfy federal, state, and local taxes, domestic or foreign, required by law or regulation to be withheld with respect to any taxable event arising as a result of this Plan. Participants may elect tax withholding above the minimum statutory amount up to forty percent (40%).

19.2 Share Withholding. With respect to tax withholding required upon the exercise of Options or SARs, upon the lapse of restrictions on Restricted Stock and Restricted Stock Units, or upon the achievement of performance goals related to Performance Shares or Performance Units, or any other taxable event arising as a result of an Award granted hereunder (collectively and individually referred to as a “Share Payment”), Participants may elect, subject to the approval of the Committee, to satisfy the withholding requirement, in whole or in part, by having the Company withhold from a Share Payment the number of Shares having a Fair Market Value on the date the tax withholding is to be determined equal to either (i) the minimum statutory withholding requirement, or (ii) such greater amount as may be permitted under then-current accounting principles to qualify the Award for equity classification. All such elections shall be irrevocable, made in writing, and signed by the Participant, and shall be subject to any restrictions or limitations that the Committee, in its sole discretion, deems appropriate.

ARTICLE 20

Successors

All obligations of the Company under this Plan with respect to Awards granted hereunder shall be binding on any successor to the Company, whether the existence of such successor is the result of a direct or indirect purchase, merger, consolidation, or otherwise, of all or substantially all of the business and/or assets of the Company.

ARTICLE 21

General Provisions

21.1 Forfeiture Events; Recoupment and Clawbacks.

| (a) | The Committee may specify in an Award Agreement that the Participant’s rights, payments, and benefits with respect to an Award shall be subject to reduction, cancellation, forfeiture, or recoupment upon the occurrence of certain specified events, in addition to any otherwise applicable vesting or performance conditions of an Award. Such events may include, but shall not be limited to, termination of employment for Cause, termination of the Participant’s provision of services to the Company, Affiliate, or Subsidiary, violation of material Company, Affiliate, or Subsidiary policies, breach of noncompetition, confidentiality, or other restrictive covenants that may apply to the Participant, or other conduct by the Participant that is detrimental to the business or reputation of the Company, any Affiliate, or Subsidiary.

| (b) | If any of the Company’s financial statements are required to be restated resulting from errors, omissions, or fraud, the Committee may (in its sole discretion, but acting in good faith) direct that the Company recover all or a portion of any Award granted or paid to a Participant with respect to any fiscal year of the Company the financial results of which are negatively affected by such restatement. The amount to be recovered from the Participant shall be the amount by which the Award exceeded the amount that would have been

##### Table of Contents

|  | EXHIBIT A

| payable to the Participant had the financial statements been initially filed as restated, or any greater or lesser amount (including, but not limited to, the entire Award) that the Committee shall determine. In no event shall the amount to be recovered by the Company be less than the amount required to be repaid or recovered as a matter of law (including but not limited to amounts that are required to be recovered or forfeited under Section 304 of the Sarbanes-Oxley Act of 2002). The Committee shall determine whether the Company shall effect any such recovery: (i) by seeking repayment from the Participant, (ii) by reducing (subject to applicable law and the terms and conditions of the applicable plan, program or arrangement) the amount that would otherwise be payable to the Participant under any compensatory plan, program, or arrangement maintained by the Company, an Affiliate, or any Subsidiary, (iii) by withholding payment of future increases in compensation (including the payment of any discretionary bonus amount) or grants of compensatory awards that would otherwise have been made in accordance with the Company’s otherwise applicable compensation practices, or (iv) by any combination of the foregoing.

| (c) | Applicability of Exchange Act Rule 10D-1 Clawback Policies.

| (i) | Notwithstanding any other requirements of Sections 21.1(a) or (b), if any Participant is subject to a compensation clawback or recoupment policy adopted by the Company in accordance with securities exchange listing standards issued pursuant to Rule 10D-1 of the Exchange Act (a “Clawback Policy”), then all Awards granted to such Participant pursuant to this Plan shall be subject to recovery under, and the terms and conditions of, such Clawback Policy.

| (ii) | In the event of any conflict between the terms of an Award or this Plan, and the terms of any Clawback Policy, the terms of any Clawback Policy shall control.

| (iii) | If an event occurs which could trigger recovery under the terms of both a Clawback Policy and Sections 21.1(a) or (b) of all of, some of, or any portion of, any Awards granted to a Participant, then the Committee (i) shall first seek recovery of the amounts required to be recovered pursuant to such Clawback Policy and (ii) then may seek recovery pursuant to Sections 21.1(a) or (b), (if the Committee elects to pursue such recovery), but (y) only if the amount of recovery under Sections 21.1(a) or (b) is reasonably determined to exceed the amount of recovery under such Clawback Policy and (z) only to the extent of such excess.

21.2 Legend. The certificates for Shares may include any legend which the Committee deems appropriate to reflect any restrictions on transfer of such Shares.

21.3 Gender and Number. Except where otherwise indicated by the context, any masculine term used herein also shall include the feminine, the plural shall include the singular, and the singular shall include the plural.

21.4 Severability. In the event any provision of this Plan shall be held illegal or invalid for any reason, the illegality or invalidity shall not affect the remaining parts of this Plan, and this Plan shall be construed and enforced as if the illegal or invalid provision had not been included.

##### Table of Contents

|  | EXHIBIT A

21.5 Requirements of Law. The granting of Awards and the issuance of Shares under this Plan shall be subject to all applicable laws, rules, and regulations, and to such approvals by any governmental agencies or national securities exchanges as may be required.

21.6 Delivery of Title. The Company shall have no obligation to issue or deliver evidence of title for Shares issued under this Plan prior to:

| (a) | Obtaining any approvals from governmental agencies that the Company determines are necessary or advisable; and

| (b) | Completion of any registration or other qualification of the Shares under any applicable national or foreign law or ruling of any governmental body that the Company determines to be necessary or advisable.

21.7 Inability to Obtain Authority. The inability of the Company to obtain authority from any regulatory body having jurisdiction, which authority is deemed by the Company’s counsel to be necessary to the lawful issuance and sale of any Shares hereunder, shall relieve the Company of any liability in respect of the failure to issue or sell such Shares as to which such requisite authority shall not have been obtained.

21.8 Investment Representations. The Committee may require any individual receiving Shares pursuant to an Award under this Plan to represent and warrant in writing that the individual is acquiring the Shares for investment and without any present intention to sell or distribute such Shares.

21.9 Employees Based Outside of the United States. Notwithstanding any provision of this Plan to the contrary, in order to comply with the laws in other countries in which the Company, its Affiliates, and/or its Subsidiaries operate or have Employees and/or Directors, the Committee, in its sole discretion, shall have the power and authority to:

| (a) | Determine which Affiliates and Subsidiaries shall be covered by this Plan;

| (b) | Determine which Employees and Directors outside the United States are eligible to participate in this Plan;

| (c) | Modify the terms and conditions of any Award granted to Employees and Directors outside the United States to comply with applicable foreign laws;

| (d) | Establish subplans and modify exercise procedures and other terms and procedures, to the extent such actions may be necessary or advisable. Any subplans and modifications to Plan terms and procedures established under this Section 21.9 by the Committee shall be attached to this Plan document as appendices; and

| (e) | Take any action, before or after an Award is made, that it deems advisable to obtain approval or comply with any necessary local government regulatory exemptions or approvals.

Notwithstanding the above, the Committee may not take any actions hereunder, and no Awards shall be granted, that would violate applicable law.

21.10 Uncertificated Shares. To the extent that this Plan provides for issuance of certificates to reflect the transfer of Shares, the transfer of such Shares may be effected on a noncertificated basis, to the extent not prohibited by applicable law or the rules of any stock exchange.

##### Table of Contents

|  | EXHIBIT A

21.11 Unfunded Plan. Participants shall have no right, title, or interest whatsoever in or to any investments that the Company, its Subsidiaries, or its Affiliates may make to aid it in meeting its obligations under this Plan. Nothing contained in this Plan, and no action taken pursuant to its provisions, shall create or be construed to create a trust of any kind, or a fiduciary relationship between the Company and any Participant, beneficiary, legal representative, or any other individual. To the extent that any individual acquires a right to receive payments from the Company or any Affiliate or Subsidiary under this Plan, such right shall be no greater than the right of an unsecured general creditor of the Company or the Subsidiary or Affiliate, as the case may be. All payments to be made hereunder shall be paid from the general funds of the Company, or the Subsidiary or Affiliate, as the case may be and no special or separate fund shall be established and no segregation of assets shall be made to assure payment of such amounts except as expressly set forth in this Plan.

21.12 No Fractional Shares. No fractional Shares shall be issued or delivered pursuant to this Plan or any Award. The Committee shall determine whether cash, Awards, or other property shall be issued or paid in lieu of fractional Shares or whether such fractional Shares or any rights thereto shall be forfeited or otherwise eliminated.

21.13 Retirement and Welfare Plans. Neither Awards made under this Plan nor Shares or cash paid pursuant to such Awards may be included as “compensation” for purposes of computing the benefits payable to any Participant under the Company’s or any Subsidiary’s or Affiliate’s retirement plans (both qualified and nonqualified) or welfare benefit plans unless such other plan expressly provides that such compensation shall be taken into account in computing a Participant’s benefit.

21.14 Deferred Compensation.

| (a) | The Committee may grant Awards under the Plan that provide for the deferral of compensation within the meaning of Code Section 409A. It is intended that such Awards comply with the requirements of Code Section 409A so that amounts deferred thereunder are not includible in income and are not subject to an additional tax of twenty percent (20%) at the time the deferred amounts are no longer subject to a substantial risk of forfeiture.

| (b) | Notwithstanding any provision of the Plan or Award Agreement to the contrary, if one or more of the payments or benefits to be received by a Participant pursuant to an Award would constitute deferred compensation subject to Code Section 409A and would cause the Participant to incur any penalty tax or interest under Code Section 409A or any regulations or Treasury guidance promulgated thereunder, the Committee may reform the Plan and Award Agreement to comply with the requirements of Code Section 409A and to the extent practicable maintain the original intent of the Plan and Award Agreement. By accepting an Award under this Plan, a Participant agrees to any amendments to the Award made pursuant to this Section 21.14(b) without further consideration or action.

21.15 Nonexclusivity of this Plan. The adoption of this Plan shall not be construed as creating any limitations on the power of the Board or Committee to adopt such other compensation arrangements as it may deem desirable for any Participant. Notwithstanding anything contained to the contrary in this Plan or Awards made hereunder, such other compensation arrangements (including, but not limited to, letter agreements, employment agreements, and severance or similar agreements) may contain different or additional vesting provisions (or other provisions) with respect to Awards made under this Plan and, in such case, the terms of such other compensation arrangements shall apply.

##### Table of Contents

|  | EXHIBIT A

21.16 No Constraint on Corporate Action. Nothing in this Plan shall be construed to: (a) limit, impair, or otherwise affect the Company’s or a Subsidiary’s or an Affiliate’s right or power to make adjustments, reclassifications, reorganizations, or changes of its capital or business structure, or to merge or consolidate, or dissolve, liquidate, sell, or transfer all or any part of its business or assets; or (b) limit the right or power of the Company or a Subsidiary or an Affiliate to take any action which such entity deems to be necessary or appropriate.

21.17 Governing Law. The Plan and each Award Agreement shall be governed by the laws of the state of Delaware, excluding any conflicts or choice of law rule or principle that might otherwise refer construction or interpretation of this Plan to the substantive law of another jurisdiction. Unless otherwise provided in the Award Agreement, recipients of an Award under this Plan are deemed to submit to the exclusive jurisdiction and venue of the federal or state courts of Delaware to resolve any and all issues that may arise out of or relate to this Plan or any related Award Agreement.

21.18 Delivery and Execution of Electronic Documents. To the extent permitted by applicable law, the Company may: (a) deliver by email or other electronic means (including posting on a Web site maintained by the Company or by a third party under contract with the Company) all documents relating to the Plan or any Award thereunder (including, without limitation, prospectuses required by the Securities and Exchange Commission) and all other documents that the Company is required to deliver to its security holders (including without limitation, annual reports and proxy statements), and (b) permit Participants to electronically execute applicable Plan documents (including, but not limited to, Award Agreements) in a manner prescribed to the Committee.

21.19 No Representations or Warranties Regarding Tax Effect. Notwithstanding any provision of the Plan to the contrary, the Company, its Affiliates and Subsidiaries, the Board, and the Committee neither represent nor warrant the tax treatment under any federal, state, local, or foreign laws and regulations thereunder (individually and collectively referred to as the “Tax Laws”) of any Award granted or any amounts paid to any Participant under the Plan including, but not limited to, when and to what extent such Awards or amounts may be subject to tax, penalties and interest under the Tax Laws.

21.20 Indemnification. Subject to requirements of Delaware law, each individual who is or shall have been a member of the Board, or a Committee appointed by the Board, or an officer of the Company to whom authority was delegated in accordance with ARTICLE 3, shall be indemnified and held harmless by the Company against and from any loss, cost, liability, or expense that may be imposed upon or reasonably incurred by him or her in connection with or resulting from any claim, action, suit, or proceeding to which he or she may be a party or in which he or she may be involved by reason of any action taken or failure to act under this Plan and against and from any and all amounts paid by him or her in settlement thereof, with the Company’s approval, or paid by him or her in satisfaction of any judgment in any such action, suit, or proceeding against him or her, provided he or she shall give the Company an opportunity, at its own expense, to handle and defend the same before he or she undertakes to handle and defend it on his/her own behalf, unless such loss, cost, liability, or expense is a result of his/her own willful misconduct or except as expressly provided by statute. The foregoing right of indemnification shall not be exclusive of any other rights of indemnification to which such individuals may be entitled under the Company’s Certificate of Incorporation or Bylaws, as a matter of law, or otherwise, or any power that the Company may have to indemnify them or hold them harmless.
