Overview of Audit Matters

SAFETY |  | HUMAN CAPITAL
We focus on company-wide accident prevention, not just OSHA compliance. We believe safety has more to do with what is in the minds of our workers and the hearts of our management. Our employees receive comprehensive training and certification in OSHA 10-Hour Safety. Managers and supervisors receive OSHA 30-hour safety training. We also provide our employees with the safety equipment they need to perform their work. Our Think 5 x 5 initiative increases worker awareness and enhances the company culture to “Safely take 5 seconds and 5 steps back” to think about their surroundings and work area to make sure it is a safe environment. We strictly adhere to all federal, state, and local regulations. |  | We provide opportunities for personal and professional growth and development and invest in leadership training, mentoring, and succession planning initiatives to equip our future leaders for generations to come. We have created in-house training courses specific to leadership, communication, relationship management, diversity and inclusion, ethics and conduct in the workplace, and many more key competencies for our employees’ development.
ENVIRONMENT |  | CONTINUOUS IMPROVEMENT
We believe that the work we perform to optimize and upgrade systems and to enable wise controls allows our customers to reduce their energy use, which in turn reduces our nation’s carbon footprint. Our emphasis on environmental stewardship and improving productivity drives our effort to become more energy efficient. We strive to minimize our environmental impacts through Board oversight, regulatory compliance, ongoing improvement investments, local specialists, and community group involvement. Our Board supplies high-level oversight of our corporate sustainability performance and material sustainability issues, as applicable, through the Nominating, Governance, and Sustainability Committee, which reviews and advises on updates from our internal Sustainability Committee, made up of a diverse set of corporate leadership, on at least a bi-annual basis. |  | We have invested in the experts, training, and internal and external knowledge transfer to ensure that we are properly scaling, achieving true buildability, and fundamentally and continuously improving our design capabilities to meet our customers’ evolving requirements. We are improving productivity by increasing use of innovative techniques in prefabrication, project design, and planning, as well as in coordination and production methods. Our investments in design and building information modeling enable us to collaborate with our customers to achieve reliable and energy efficient construction outcomes and to eliminate unnecessary waste. We work to identify, develop, and implement new materials, products, and methods that can achieve greater productivity and more efficient and sustainable outcomes.
OUR COMMUNITIES |  | DIVERSITY AND INCLUSION
We believe in making a positive difference in people’s lives and maintaining the health and welfare of the communities where we live and work. We promote, encourage, and support a diverse range of corporate social responsibility activities. Our employees’ involvement in the many initiatives we support is integral to the success of our impact in the communities where we operate. |  | We are an equal opportunity employer, and we welcome and celebrate our teams’ differences, experiences, and beliefs. We expect all employees to be treated with dignity and respect in an environment free from discrimination and harassment regardless of race, color, religion, sex, sexual orientation, gender identity or expression, national origin, age, disability, veteran status, genetic information, or any other protected class. Supporting our employees and representing the communities we serve are important to our leadership team. Diversity and inclusion is a competitive advantage that helps drive growth and innovation. The Compensation and Human Capital Committee of our Board of Directors provides oversight on our diversity and inclusion strategy.

1 Election of Directors In the vote on the election of director nominees nominated by the Board of Directors to serve until the 2026 Annual Meeting, stockholders may: |  | ● Vote for all nominees ● Withhold authority from the proxy holders to vote for all nominees ● Vote for all nominees except those specified |  | FOR all nominees |  | The Board recommends a vote FOR all nominees. If a quorum is present, the ten nominees for election as directors receiving the greatest number of votes properly cast at the Annual Meeting, or at any adjournments or postponements thereof, will be elected. The Company has a policy to address the resignation of an incumbent director who receives more votes “withheld” than votes “for” his or her election. See the subsection titled “Director Resignation Policy” below. |  | Votes withheld from any director are counted for purposes of determining the presence or absence of a quorum for the transaction of business. Broker non-votes will be counted toward a quorum, but will not be taken into account in determining the outcome of the election.

General Meeting Information

What constitutes a quorum?

A quorum is the minimum number of shares required to hold a meeting. Consistent with Delaware law and the Company’s Bylaws, the holders of a majority in number of the total outstanding shares of stock of the Company entitled to vote at the meeting, present in person or represented by proxy, constitutes a quorum as to that matter. As of the Record Date, 35,328,058 shares of Common Stock, representing the same number of votes, were outstanding. Therefore, the presence of holders of Common Stock representing at least 17,664,030 votes will be required to establish a quorum.

What is the difference between holding shares as a stockholder of record and as a beneficial owner of shares held in street name?

If your shares are registered directly in your name with our transfer agent, Equiniti Trust Company (formerly American Stock Transfer & Trust Company), you are considered the stockholder of record with respect to those shares, and the accompanying Notice of Annual Meeting was sent directly to you by the Company.

If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the beneficial owner of shares held in “street name,” and the Notice of Annual Meeting was forwarded to you by your bank, broker, or other intermediary. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to direct that organization on how to vote the shares held in your account.

What happens if I do not give specific voting instructions?

If you are a stockholder of record and you sign and return a proxy card without giving specific voting instructions, then the proxy holders will vote your shares FOR the nominees listed in Proposal 1, FOR the ratification of the appointment of Deloitte & Touche LLP as the Company’s auditors for 2025 in Proposal 2, and FOR approval with respect to the Company’s executive compensation program in Proposal 3.

If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, under New York Stock Exchange (“NYSE”) rules, the organization that holds your shares may generally vote on routine matters but cannot vote on non-routine matters (including uncontested director elections and “Say on Pay”). If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter (including uncontested director elections and “Say on Pay”), the organization that holds your shares will inform our election inspectors that it does not have the authority to vote on this matter with respect to your shares and your shares will not be voted. This is generally referred to as a “broker non-vote.” When our election inspectors tabulate the votes for any particular matter, broker non-votes will be counted for purposes of determining whether a quorum is present but will not otherwise be counted. We encourage you to provide voting instructions to the organization that holds your shares.

General Meeting Information

Can I change my vote after I return my proxy card?

Yes. A proxy may be revoked by a record stockholder at any time before it is voted by (i) returning to the Company another properly signed proxy bearing a later date, (ii) delivering a written revocation to the Secretary of the Company no later than the close of business on May 15, 2025, or (iii) attending the Annual Meeting, or any adjourned session thereof, and voting the shares covered by the proxy in person. If your stock is held in street name, you must follow the instructions of the broker, bank, or nominee as to how to change your vote.

Who pays to prepare, mail, and solicit the proxies?

The Company will pay the expense of soliciting proxies. In addition to the solicitation of proxies by use of the mails, the Company may use the services of its officers, directors, and regular employees as well as brokerage houses and other stockholders to solicit proxies personally and by mail, telephone, or email communication. The Company will reimburse brokers and other persons for their reasonable charges and expenses in forwarding soliciting materials to their principals. Officers and employees of the Company will receive no compensation in addition to their regular salaries to solicit proxies.

Who tabulates the votes?

Votes cast by proxy or in person at the Annual Meeting will be counted by two people appointed by the Company to act as election inspectors for the Annual Meeting.

Could other matters be decided at the Annual Meeting?

We do not know of any matters that may be properly presented for action at the Annual Meeting other than Proposals 1, 2, and 3. If other business does properly come before the Annual Meeting, the persons named in the proxy intend to act on those matters as they deem advisable. With respect to shares held in street name, the nominee may vote on those matters, subject to the NYSE’s rules on the exercise of discretionary authority.

What happens if the Annual Meeting is postponed or adjourned?

Your proxy may be voted at the postponed or adjourned Annual Meeting. You will still be able to change your proxy until it is voted.

How can I find the Company’s governance documents, such as its corporate Governance Standards, Director Independence Guidelines, Code of Conduct, and Board committee charters?

All these documents can be found on our website at h ttp://investors.comfortsystemsusa.com under the “Governance” tab. Please note that documents and information on our website are not incorporated into this proxy statement by reference. These documents are also available in print by writing to the Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, Texas 77057.

How can I receive a copy of the Annual Report?

The Annual Report to Stockholders, which includes the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, accompanies this proxy statement and may also be accessed through our website—http://investors.comfortsystemsusa.com.

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

We plan to announce the preliminary voting results at the Annual Meeting and to publish the final results in a current report on Form 8-K, which we will file with the United States Securities and Exchange Commission (the “SEC”) and make available on our website—http://investors.comfortsystemsusa.com.

When and where will a list of stockholders be available?

A list of stockholders of record will be available for examination at the Company’s headquarters during ordinary business hours for the ten days prior to the Annual Meeting.

PROPOSAL 1

Election of Directors

| THE BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE ELECTION OF THE TEN DIRECTOR NOMINEES.

Board of Directors

Ten directors will be elected at the Annual Meeting to serve for a one-year term expiring at the Annual Meeting of Stockholders expected to be held in May 2026.

The nominees for election at the Annual Meeting are:

● | Darcy G. Anderson | ● | Rhoman J. Hardy | ● | Brian E. Lane | ● | Franklin Myers | ● | Constance E. Skidmore
● | Herman E. Bulls | ● | Gaurav Kapoor | ● | Pablo G. Mercado | ● | William J. Sandbrook | ● | Cindy L. Wallis-Lage

(each a “Nominee” and collectively the “Nominees”). Mr. Kapoor took office in August 2024 and is thus standing for his first election at an annual meeting of stockholders.

If elected, each Nominee has agreed to serve for a term of one year expiring at the 2026 Annual Meeting of Stockholders. It is expected that all the Nominees will be able to serve, but if any Nominee is unable to serve, the proxies reserve discretion to vote, or refrain from voting, for a substitute nominee.

Vance W. Tang informed the Company on March 19, 2025 that he is retiring from the Board effective May 16, 2025 and, as a result, will not stand for re-election at the 2025 Annual Meeting. The Company thanks Mr. Tang for his guidance and service to the Company and the Board. As a result of Mr. Tang’s decision to retire, the Board will reduce the number of directors constituting the Board from 11 to 10, effective as of May 16, 2025.

The Board has adopted Independence Guidelines to assist the Board in making independence determinations relating to members of the Board.

Director Nomination by Stockholders

The Board will consider director candidates recommended by stockholders for inclusion on the slate of directors nominated by the Board. Any stockholder may submit a candidate or candidates for consideration in conformity with the Bylaws and as set forth hereafter under the caption “Stockholder Proposals for the 2026 Annual Meeting.” Stockholders desiring to recommend a candidate must submit the recommendation to the Nominating, Governance, and Sustainability Committee c/o the Corporate Secretary, Comfort Systems USA, Inc., 675 Bering Drive, Suite 400, Houston, Texas 77057. If a nominating stockholder is not a record holder, the stockholder must provide the same evidence of eligibility as set forth in Exchange Act Rule 14a-8(b)(2).

At the time the nominating stockholder submits the recommendation, the candidate must submit all personal information that the Company would be required to disclose in a proxy statement in accordance with Exchange Act rules. In addition, at that time the candidate must:

● | Certify that he or she meets the requirements to be: (a) independent under the NYSE’s listing standards and the Board’s Independence Guidelines, and (b) a non-employee director under Rule 16b-3 of the Exchange Act;
● | Consent to serve on the Board, if nominated and elected; and

In selecting nominees, particular consideration is given to those individuals who have substantial achievement in their personal and professional pursuits and whose talents, experience, and integrity would be expected to contribute to the best interests of the Company and to long-term stockholder value. In evaluating candidates, the committee considers various qualities and skills that it believes will benefit the Board and the stockholders, including, without limitation, general management experience, specialization in the Company’s principal business activities or finance, significant experience in issues encountered by public companies, and contribution to the diversity of the Board.

Corporate Governance

Stockholder Engagement

Throughout the year, we meet regularly with investors and actively seek their input on topics related to our performance and our compensation and governance policies, as well as a wide variety of other topics on which they may have feedback, so that we may address any questions or concerns of our stockholders. During 2024, executive officers held more than 200 meetings, including those held during the course of eleven investor conferences and ten roadshows. This process is led by Brian Lane, President, Chief Executive Officer, and member of the Board, and William George, Executive Vice President and Chief Financial Officer. In addition, as appropriate, we work to clarify and expand our disclosures as we prepare our next proxy statement based on such discussions. We value our stockholders’ input and welcome feedback through our ongoing engagement practices.

Communications With the Board

Stockholders and other interested parties may communicate directly with the Board by writing to Comfort Systems USA, Inc., Board of Directors, 675 Bering Drive, Suite 400, Houston, Texas 77057. The Chair of the Board will review these communications and will determine appropriate steps to address them. A stockholder wishing to communicate directly with the non-employee members of the Board may address the communication to “Non-Employee Directors, c/o Board of Directors” at the address listed above. These communications will be handled by the Chair of the Board, who is currently designated to preside at meetings of non-employee directors. Finally, communications can be sent directly to individual directors by addressing letters to their individual name, c/o the Board of Directors, at the address listed above. All communications received by the Company are sent directly to the Board or appropriate director.

Board Leadership Structure and Self-Evaluation Process

The Board does not have a formal policy regarding whether the position of Chair of the Board may be filled by the Company’s Chief Executive Officer. Instead, the Board has adopted a fluid approach to the Board’s leadership structure that allows for variations depending on the circumstances and changing needs of the Company over time.

Mr. Myers has served as a director since 2005 and has served as the Company’s Chair of the Board since May 2014. The Board has determined that Mr. Myers meets the independence requirements of the NYSE listing standards, the Board’s Independence Guidelines, and the rules and regulations under the Exchange Act. The Board has carefully considered its leadership structure and determined that currently it is in the best interests of the Company and its stockholders for the roles of Chair of the Board and Chief Executive Officer to be filled by different individuals. This structure allows the Chief Executive Officer to focus on the Company’s day-to-day operations.

Since the Company has an independent, non-executive Chair of the Board, the Company has determined that the role of a Lead Director is not currently necessary. The Board may appoint a Lead Director to coordinate the activities of the independent directors in the future at its discretion.

Pursuant to the Board’s policy, the Board conducts an annual self-evaluation process as follows: (i) each director evaluates the Board as a whole; (ii) each member of the Audit Committee, the Compensation and Human Capital Committee, and the Nominating, Governance, and Sustainability Committee evaluates the respective committee(s) on which he or she serves; and (iii) each director prepares an individual performance-related self-evaluation of himself or herself as well as other individual members of the Board. In connection with this annual self-evaluation, the Board considers whether the current leadership structure continues to be appropriate for the Company. The Board believes that directors should be responsive to the Company’s evolving circumstances and objectives, and that the Board’s leadership structure should adapt when necessary.

The Board’s Role in Risk Oversight

The Company’s full Board is actively involved in overseeing the Company’s risk management process. These activities are aligned with the Company’s strategy. The Audit Committee, Compensation and Human Capital Committee, and Nominating, Governance, and Sustainability Committee consider risks that fall within their respective areas of responsibility. For example, the Nominating, Governance, and Sustainability Committee is formally scheduled to review sustainability matters relevant to the Company and its operations bi-annually, and the Audit Committee reviews the enterprise risk management matrix, which addresses sustainability risks, annually. Further, in recognition of the importance of maintaining the confidence of all Company stakeholders, the Board considers information technology and data security risk, specifically cybersecurity risk, a premier area of focus. The Company’s Chief Information Security Officer (“CISO”) works and reports separately from the Information Technology department, an arrangement meant to allow the CISO to advise the Company most effectively on cybersecurity and related risks, and reports directly to our executive management team. The Board oversees information technology, data security, and cybersecurity risk management through regular reports and presentations from the CISO and other management members. In addition, a group of the Company’s executive officers serve on a committee (the “Risk Committee”) that is directly responsible for the Company’s risk

management process. The Company’s President and Chief Executive Officer, a member of the Board, serves on the Risk Committee; however, the Risk Committee is a committee of management, not of the Board. The Risk Committee meets at least annually to define and improve the risk-mapping process and considers any appropriate updates at least quarterly. All members of the Risk Committee attended at least 75% of the quarterly meetings held in 2024. Any risks that are identified through the Company’s compliance and ethics program are included in the Risk Committee’s processes, along with operational, financial, environmental, cybersecurity, social, governance, and strategic risks. The Risk Committee presents comprehensive reports directly to the Board at least annually through the enterprise risk management matrix, which, as explained above, is reviewed by the Audit Committee.

Director Resignation Policy

Effective March 8, 2017, the Board adopted a Director Resignation Policy to address the situation in which a nominee for director in an uncontested election to the Board receives more votes “withheld” than votes “for” his or her election. The policy provides that any incumbent nominee for director in an uncontested election who receives a greater number of votes affirmatively “withheld” with respect to his or her election than votes “for” such election (a “majority withhold vote”) shall promptly tender his or her resignation to the Chair of the Board following certification of the stockholder vote. The Nominating, Governance, and Sustainability Committee will promptly consider the tendered resignation and recommend to the Board whether to accept or reject the resignation or take other action, such as rejecting the tendered resignation and addressing the apparent underlying causes of the majority withheld vote. In making its recommendation, the committee will consider all relevant factors, including, but not limited to, (i) the underlying reasons why stockholders withheld their votes (if ascertainable), (ii) the length of service and qualifications of the director whose resignation has been tendered, (iii) the director’s contributions to the Board and the Company, (iv) the overall composition of the Board and compliance with applicable laws, regulations, governing documents, and stock exchange listing standards, (v) the availability of other qualified candidates, and (vi) whether accepting the resignation is in the best interests of stockholders and the Company. The Board will act on the committee’s recommendation no later than its first regularly scheduled meeting following certification of the stockholder vote, but in no case later than 120 days following the vote certification. Following the committee’s recommendation and the Board’s decision, the Company will promptly publicly disclose its decision whether to accept or reject such tendered resignation in a periodic or current report filed or furnished in accordance with SEC rules.

Any director who tenders his or her resignation under the Director Resignation Policy will not participate in the committee recommendation or Board consideration of the resignation. However, such director will otherwise remain as an active Board member unless and until the resignation becomes effective. If a majority of the Nominating, Governance, and Sustainability Committee members receive a majority withhold vote at the same election, then the independent directors who did not receive a majority withhold vote will appoint a committee amongst themselves to consider the tendered resignations. If the only directors who did not receive a majority withhold vote in the same election constitute fewer directors than a majority of the Board, then all the independent directors may participate in the Board consideration of the tendered resignations, except that no director will participate in the vote on his or her own resignation.

While this summary reflects the current terms of the Director Resignation Policy, the Board retains the power to amend and administer the policy as the Board, in its sole discretion, determines is appropriate. The Director Resignation Policy is published under the “Governance” tab on our website, http://investors.comfortsystemsusa.com, and is also available by written request to Comfort Systems USA, Inc., Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, Texas 77057.

Director Compensation for 2024

In 2024, each director who was not an employee of the Company or one of its subsidiaries received, in quarterly installments, an annual cash fee for his or her service as follows: $80,000 for service on the Board; an additional $30,000 for service as the chair of the Audit Committee; an additional $20,000 for service as the chair of the Compensation and Human Capital Committee or the Nominating, Governance, and Sustainability Committee. For 2024, the rate of the annual cash fee for service as the chair of the Board was increased from $100,000 to $125,000 effective as of the 2024 Annual Meeting of Stockholders, and was blended based on those two rates for 2024. The Board approved this increase following the recommendation of the Nominating, Governance, and Sustainability Committee, which had based its recommendation on an analysis of several factors, including the committee’s review of survey and peer group data (based on the same peer group used for executive compensation purposes) prepared by Compensation Advisory Partners, our compensation consultant, which indicated that the increased amount was more consistent with the market median. Directors are also reimbursed for expenses incurred in connection with attending meetings.

Each non-employee director who continues in office or is elected at an annual stockholder meeting receives an award of fully-vested shares of Common Stock having a fair market value on the grant date equal to approximately $160,000. Each non-employee director who is initially elected or appointed to serve on the Board other than at any annual stockholder meeting will be granted a prorated number of fully vested shares of Common Stock based on the number of days between the effective date of appointment and the next annual stockholders’ meeting. In connection with Mr. Kapoor’s appointment in August 2024, Mr. Kapoor was granted fully-vested shares of Common Stock having a fair market value on the grant date of $126,507. Pursuant to the Company’s 2017 Omnibus Incentive

Director Compensation for 2024

Plan, the maximum grant date fair value of awards granted to an individual non-employee director in any calendar year may not exceed $400,000. The Board has adopted stock ownership requirements, pursuant to which each non-employee director must own shares of Common Stock (or share equivalents) having a value equal to ten times the director’s annual cash fees for service on the Board (excluding any additional fees for service as the chair of the Board or any committee of the Board and any other compensation or expense reimbursement received by the director) within five years of being elected or appointed to the Board. The Nominating, Governance, and Sustainability Committee evaluates each director’s stock ownership level on an annual basis. At the time of such evaluation, the value of the stock owned by each director is determined by reference to the higher of: (i) the original share (or share equivalent) purchase or issuance price, and (ii) the value of the share (or share equivalent) price at the time of determining compliance with these stock ownership requirements. The Nominating, Governance, and Sustainability Committee may modify these stock ownership requirements in its reasonable discretion and is authorized to make exceptions to these stock ownership requirements when special circumstances arise. All non-employee directors are currently in compliance with these ownership requirements or are in their initial five-year phase in period.

Directors who are employees of the Company or one of its subsidiaries receive no additional compensation for serving as directors. The following table discloses the compensation earned by, or paid or awarded to, as the case may be, each of the Company’s non-employee directors for 2024.

(1) | Brian E. Lane also served as a member of the Board during 2024 but was an employee of the Company in 2024 and received no additional compensation for his service on the Board. Mr. Lane’s compensation for his service as an employee for 2024 is disclosed in the “Summary Compensation Table” included elsewhere in this proxy statement.
(2) | Amounts in this column represent fees earned in 2024. For Mr. Kapoor, the amount reflects a prorated portion of the annual cash fee based on his appointment to the Board on August 1, 2024. For Mr. Myers, the amount includes his annual cash fee for service as chair of the Board, which calculated on a blended basis for 2024 to account for the increase in such annual fee effective May 17, 2024 from $100,000 per year to $125,000 per year. Finally, Mr. Tang served as the chair of the Nominating, Governance, and Sustainability Committee until May 17, 2024, and Ms. Wallis-Lage succeeded him for the remainder of the year. Thus, Mr. Tang and Ms. Wallis-Lage each received a prorated additional annual fee for service as chair of the Nominating, Governance, and Sustainability in 2024, as reflected above.

As described above, Mr. Kapoor received 385 shares of Common Stock in connection with his appointment in 2024. The aggregate grant date fair value of the shares was computed in accordance with FASB ASC Topic 718, disregarding the effect of estimated forfeitures, and is equal to the number of shares granted multiplied by the average of the high and low price of the Common Stock on the date of grant.
(4) | The Company maintains a visiting director’s office for all members of the Board at its headquarters in Houston, Texas. The office is available on a first-come-first-served basis for all directors. In accordance with SEC regulations, perquisites that in the aggregate total less than $10,000 are not required to be disclosed. No amount is included in the table above with respect to the availability and use of this office.

PROPOSAL 2

Ratification of the Selection of Independent Auditors

| THE BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE SELECTION OF DELOITTE & TOUCHE LLP AS OUR INDEPENDENT AUDITORS.

The Audit Committee has re-appointed Deloitte & Touche LLP as the Company’s independent auditors for the year ending December 31, 2025. Deloitte & Touche LLP was the Company’s independent auditor for the year ended December 31, 2024.

We expect that representatives of Deloitte & Touche LLP will be present at the Annual Meeting to respond to appropriate questions, and they will have the opportunity to make a statement if they desire.

The affirmative vote of holders of a majority of the shares of Common Stock voted at the Annual Meeting is required to ratify the appointment of Deloitte & Touche LLP as the Company’s independent auditors for 2025. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider its selection, but it still may decide to retain Deloitte & Touche LLP. Even if the appointment is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent accounting firm at any time during the year if the committee determines that such a change would be in the best interests of the Company and its stockholders.

Relationship with Independent Auditors

The Audit Committee has selected Deloitte & Touche LLP as independent auditors for the Company for the year ending December 31, 2025.

Deloitte & Touche LLP acted as independent auditors for the Company for the year ended December 31, 2024. Fees disbursed by the Company and its subsidiaries for professional services rendered by Deloitte & Touche LLP during 2024 and 2023 were as follows:

Description |  | 2024 |  |  | 2023 |
Audit Fees |  | $ | 3,689,501 |  |  | $ | 2,250,247 |
Audit-Related Fees |  | $ | 0 |  |  | $ | 0 |
Tax Fees |  | $ | 0 |  |  | $ | 0 |
All Other Fees |  | $ | 2,051 | (1) |  | $ | 2,051 | (1)

(1) | This amount represents the Company’s subscription fee for the Deloitte Accounting Research Tool (“DART”), a comprehensive web-based library of accounting and financial disclosure literature.

The amount of audit fees for 2024 is based on a fees estimate determined with input from Deloitte & Touche LLP for audit services provided to us in connection with the audit of our 2024 financial statements. The final audit fees for those services may be more or less than the amount reflected on this table.

The Audit Committee has established pre-approval policies and procedures applicable to all services provided by the Company’s independent auditors to the Company, pursuant to which the committee reviews for approval each service expected to be provided by the independent auditors, and is provided with sufficiently detailed information so that it can make well-reasoned assessments of the impact of the services on the independence of the auditors. In 2024, all the fees paid to the Company’s auditors were approved by the Audit Committee. Pre-approvals include pre-approved cost levels or budgeted amounts (or a range of cost levels or budgeted amounts). Any proposed service that would exceed pre-approved cost levels or budgeted amounts also requires pre-approval. Substantive changes in terms, conditions, or fees resulting from changes in the scope, structure, or other items regarding pre-approved services will also be pre-approved if necessary. The pre-approvals may include services in categories of audit services (including consultation to support such audits), audit-related services (items reasonably related to the performance of the audit or review of the financial statements), tax services (tax compliance, tax planning, and tax advice), and other services (services permissible under the SEC’s auditor independence rules, typically routine and recurring type services that would not impair the independence of the auditor).

PROPOSAL 3

Advisory Vote to Approve the Compensation of the Named Executive Officers

| THE BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE APPROVAL OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS.

The Board recognizes that executive compensation is an important matter for our stockholders. As described in detail in the “Compensation Discussion and Analysis” (the “CD&A”) section elsewhere in this proxy statement, the Compensation and Human Capital Committee is tasked with the implementation of our executive compensation philosophy, and the core of that philosophy has been and continues to be to pay the Company’s executive officers based on Company performance. In particular, the Compensation and Human Capital Committee strives to attract, retain, and motivate exceptional executive officers, to reward past performance as measured against pre-established goals, to provide incentives for future performance, and to align executive officers’ long-term interests with the interests of our stockholders. To do so, the Compensation and Human Capital Committee uses a combination of short- and long-term incentive compensation to reward near-term performance and to encourage our executive officers’ commitment to our long-term strategic business goals. It is the intention of the Compensation and Human Capital Committee that our executive officers be compensated competitively and consistently with our business goals and strategy, sound corporate governance principles, and stockholder interests and concerns. As discussed further in the CD&A, the Compensation and Human Capital Committee retains an independent compensation consultant and reviews survey and peer group data to ensure that compensation for key positions is properly aligned with market practices. The Company’s commitment to aligning pay with performance is evidenced by the compensation paid to or earned by the Company’s Named Executive Officers.

As described in the CD&A, we believe that our executive compensation program is effective, appropriate, and strongly aligned with the long-term interests of our stockholders and that the compensation provided to the Named Executive Officers (including potential payouts upon a termination of employment or change in control) is reasonable and not excessive. As you consider this Proposal Number 3, we urge you to read the CD&A section of this proxy statement for additional details on our executive compensation program, including more detailed information about our compensation philosophy and objectives and the compensation paid or awarded to the Named Executive Officers, and to review the tabular disclosures regarding Named Executive Officer compensation together with the accompanying narrative disclosures in the “Summary of Executive Compensation” section of this proxy statement.

Congress enacted the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank”), which requires a non-binding advisory “Say on Pay” vote and gives our stockholders the opportunity to express their views on the compensation of the Named Executive Officers. We value the opportunity to have our stockholders provide us with such a vote on executive compensation at the Annual Meeting.

As an advisory vote and as prescribed by Dodd-Frank, Proposal Number 3 is not binding on the Board or the Compensation and Human Capital Committee, will not overrule any decisions made by the Board or the Compensation and Human Capital Committee, and will not require the Board or the Compensation and Human Capital Committee to take any action. Although the vote is non-binding, the Board and the Compensation and Human Capital Committee value the opinions of our stockholders and will consider the outcome of the vote when making future executive compensation decisions. In particular, if there are a significant number of votes against the Named Executive Officers’ compensation as disclosed in this proxy statement, we will consider our stockholders’ concerns, and the Board and the Compensation and Human Capital Committee will evaluate whether any actions are necessary to address those concerns. Unless the Board modifies its policy on the frequency of “Say on Pay” votes, the next “Say on Pay” vote will be held in 2026. The next advisory vote on the frequency for “Say-on-Pay” stockholder votes will be held no later than at the Company’s 2029 Annual Meeting.

The Board of Directors is asking that stockholders cast a non-binding, advisory vote FOR the following resolution:

“RESOLVED, that the compensation paid or awarded to the Company’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables, and narrative discussion, is hereby APPROVED on an advisory basis.”

We finished 2024 with increased revenue (revenue of $7.03 billion in 2024, as compared to revenue of $5.21 billion in 2023), record earnings (net income of $522.4 million, or $14.60 per diluted share, in 2024, as compared to net income of $323.4 million, or $9.01 per diluted share, in 2023), increased cash flow (operating cash flow of $849.1 million in 2024, as compared to $639.6 million in 2023), and a notable surge of backlog (backlog was $5.99 billion as of December 31, 2024, as compared to $5.68 billion as of September 30, 2024 and $5.16 billion as of December 31, 2023). As a result of this remarkable performance, the Named Executive Officers each received 200.0% of their respective earnings-per-share (“EPS”) target awards and 200.0% of their respective free cash flow (“FCF”) target awards under the corporate financial incentive portion of the Company’s 2024 annual incentive plan, as further described below.

Compensation and Governance Practices

Below we highlight certain of our practices that we consider good governance features of our executive compensation program.

COMPENSATION PRACTICES
| A majority of each executive officer’s compensation is at-risk (i.e., variable and not fixed).* |  |  | Executive officers and directors are subject to stock ownership requirements.
| A majority of each executive officer’s compensation is tied to the Company’s financial performance and/or stock price.* |  |  | The Company has adopted a compensation clawback policy and an anti-hedging/pledging policy that apply to all executive officers.
| 50% of each executive officer’s annual equity award targets are subject to the Company achieving specific performance goals over a 3-year time horizon.* |  |  | The Committee and management routinely engage independent third parties, including an independent compensation consultant and the Company’s stockholders, to advise and provide feedback on executive compensation matters.

* | Assuming target performance is achieved, when applicable, and based on grant date values of annual equity awards. Does not take into account any one-time equity awards outside of the annual equity award cycle.

Consideration of Stockholder Advisory Vote

Consideration of Stockholder Advisory Vote

In designing the Company’s overall executive compensation program, the Committee also values and considers stockholder input. While evaluating the Company’s executive compensation program, the Committee considered the stockholder advisory vote on the compensation paid to the Company’s named executive officers that was taken in 2024.

The Committee viewed the outcome of that advisory vote—approval by more than 95% of the shares voted—as indicating that the Company’s stockholders support the Company’s overall approach to executive compensation and made no changes to the structure of our executive compensation program as a direct result of the vote.

HISTORICAL SAY-ON-PAY APPROVAL

Compensation Philosophy and Objectives

The Committee evaluates each element of the overall executive compensation program to ensure that it supports the Committee’s objectives of:

OUR COMPENSATION OBJECTIVES
| providing competitive total compensation consistent with job scope, experience, and related skills; |  |  | avoiding unnecessary and imprudent risks; and
| linking bonus opportunities to the Company’s performance; |  |  | attracting and motivating talented executive officers and minimizing turnover of senior-level Company employees, which contributes to the stability and continuity of senior leadership.
| granting equity compensation at competitive levels, a significant portion of which is performance-based; |

Against that backdrop, the Company’s executive compensation program is designed to:

OUR COMPENSATION PROGRAM IS DESIGNED TO
| pay competitive levels of compensation; |  |  | align the interests of the Company’s executive officers with the long-term interests of the Company’s stockholders; and
| link executive pay to Company performance by making a significant portion of pay variable and not fixed; |  |  | reward long-term results.

To achieve these objectives, in addition to the objectives referenced in the “Elements of Compensation” subsection below, the Committee implements a “pay-for-performance” philosophy using the guiding principles that:

1 | compensation should be incentive-driven, with a balanced short-term and long-term focus;
2 | a significant portion of pay for executive officers should be “at-risk;”
3 | a significant portion of annual incentive compensation should be tied to the overall performance of the Company;
4 | a portion of annual incentive compensation should be tied to individual performance; and
5 | a significant portion of long-term incentive awards should be contingent upon Company performance.

Compensation Discussion and Analysis

Compensation Philosophy and Objectives

Role of the Chief Executive Officer

The Company’s Chief Executive Officer makes annual recommendations to the Committee regarding the compensation arrangements of the Company’s executive officers (except that he makes no recommendation with respect to his own compensation arrangements). The Committee considers the recommendations during its regularly-scheduled meetings, and may choose to adopt the recommendations, in whole or in part, at the Committee’s sole discretion. The Committee is responsible for making all decisions regarding executive compensation.

Independent Compensation Consultant; Use of Market Data

In 2024, the Committee retained a compensation consultant, Compensation Advisory Partners, to advise the Committee on the design and administration of the Company’s short-term and long-term incentive compensation programs and to provide a comprehensive analysis of executive compensation survey data and market trends. The Committee reviewed the services provided by Compensation Advisory Partners and believes that Compensation Advisory Partners was independent in providing executive compensation consulting services to the Committee. In making this determination, the Committee noted that during 2024:

● | Compensation Advisory Partners did not provide any services to the Company or management other than services requested by or with the approval of the Committee, and its services were limited to advising on executive and director compensation-related matters. Specifically, Compensation Advisory Partners did not provide, directly or indirectly through any affiliates, any non-executive employee compensation services, such as pension consulting or human resource outsourcing;
● | Compensation Advisory Partners maintained a conflict of interest policy, which was provided to the Committee, with specific policies and procedures designed to ensure independence;
● | Fees paid to Compensation Advisory Partners by the Company during 2024 were less than 1% of their total revenue;
● | None of the Compensation Advisory Partners consultants working on Company matters had any business or personal relationship with Committee members;
● | None of the Compensation Advisory Partners consultants working on Company matters had any business or personal relationship with any executive officer of the Company; and
● | None of the Compensation Advisory Partners consultants working on Company matters owned Company stock.

The Committee monitors the independence of its outside consultants on a periodic basis.

During 2024, the Committee consulted with Compensation Advisory Partners regarding the Company’s short-term and long-term incentive compensation programs, as well as market trends and executive compensation peer group and other survey data, as described below. Compensation Advisory Partners has provided the Committee with detailed analysis and recommendations on the structure of the Company’s short-term and long-term incentive compensation programs in terms of design, metrics, and payout opportunities, and the Committee intends to continue to periodically refine the Company’s short-term and long-term incentive compensation programs based on a number of factors, including its compensation consultant’s recommendations, market trends in the Company’s industry, and general economic conditions. In 2024 Compensation Advisory Partners also advised the Nominating, Governance, and Sustainability Committee on non-employee director compensation.

Peer Group and the Benchmarking Process

The Committee reviews executive compensation levels annually using peer group and other survey data provided by its compensation consultant. The Committee does not attempt to set executive compensation at a pre-defined percentile of the market, but the Committee does use comparative data in an effort to be better informed in its executive compensation-related decisions.

The Committee believes that, due to the Company’s unique position in its industry, there are no directly comparable companies in the broader market for the purpose of determining appropriate compensation comparators for the compensation of its executive officers and, for this reason, does not depend solely on a “peer group” to determine executive officer compensation. It does, however, review executive compensation against compensation paid to executive officers holding similar positions in certain select “peer group” companies. For purposes of making 2024 executive compensation decisions, this peer group was as follows:

Use of Tally Sheets

2024 PEER GROUP
● EMCOR Group, Inc. | ● MasTec, Inc. | ● KBR, Inc.
● ABM Industries Incorporated | ● Tutor Perini Corporation | ● Valmont Industries, Inc.
● Granite Construction Incorporated | ● Dycom Industries, Inc. | ● MYR Group Inc.
● Primoris Services Corporation | ● Tetra Tech, Inc. | ● IES Holdings, Inc.
● APi Group Corporation | ● Sterling Infrastructure, Inc. | ● Limbach Holdings, Inc.
● Ameresco, Inc. | ● Oshkosh Corporation | ● MDU Resources Group, Inc.

In determining the appropriateness of the foregoing companies, the Committee, in consultation with Compensation Advisory Partners, considered factors such as historical revenue, the company’s earnings before interest, taxes, depreciation, and amortization (EBITDA), and total shareholder return, in addition to the primary industry, enterprise value, and market capitalization of each company. In August 2024, this peer group was further refined by the Committee, in consultation with Compensation Advisory Partners and considering these same factors, to remove Ameresco, Inc. and Limbach Holdings, Inc. and to add Fluor Corporation and AECOM, as the Committee determined that such revisions would realign the peer group to better reflect the factors as set forth above, including historical revenue and market capitalization.

The Committee uses a combination of the peer group and survey data from certain other industry companies to provide a general market review of the reasonableness of total compensation levels for the Company’s executive officers; however, the Committee does not use the peer group or survey data for any other purpose or otherwise formally benchmark the compensation of the Company’s executive officers.

Use of Tally Sheets

The Committee routinely uses tally sheets to assist it in analyzing executive officers’ total compensation. Tally sheets provide the Committee with information about the following components of compensation paid or granted over the preceding three-year period: cash compensation, including salary and annual incentive compensation, and long-term incentive compensation. These tally sheets also provide an estimate of amounts payable in the event of a voluntary or involuntary termination of employment, including by reason of death, disability, or a change in control resulting in termination of employment. The Committee also reviews information regarding long-term incentive awards, including statistics on share usage, analysis of current “in-the-money” values of outstanding option grants and current values of time-vesting restricted stock unit (“RSU”) and performance-vesting restricted stock unit (“PSU”) awards, and a summary of current and past performance results.

Chief Executive Officer Compensation

Each year, the Committee meets in executive session (i.e., separately from management) to evaluate the Chief Executive Officer’s performance and determine his total compensation. The Committee conducts an assessment of the Chief Executive Officer’s performance as well as an assessment of other relevant factors, such as the Company’s performance, individual tenure, and position tenure, and sets the Chief Executive Officer’s compensation for each year based on the Committee’s assessment of these factors. Although the Committee does not attempt to set the Chief Executive Officer’s target compensation at any specific percentile of compensation for peer group companies, the Committee does use peer group and other survey data as context in reviewing the Chief Executive Officer’s overall compensation levels and approving compensation actions, as described above. Based on this data, the Committee determined that the Chief Executive Officer’s target compensation was below the market median in 2024.

Elements of Compensation

Elements of Compensation

The Company’s executive compensation program consists of four basic elements:

| COMPENSATION ELEMENT |  | OBJECTIVE |  | KEY CHARACTERISTICS
|  | BASE SALARY |  | ● Provide a fixed level of cash compensation for performing day-to-day functions ● Attract and retain strong executive talent |  | ● Levels are evaluated annually by the Committee ● For 2024, base salaries were established based on a number of factors, including each executive’s performance and time in his or her role, advice from the Committee’s independent compensation consultant, and analysis of peer group and survey data and economic conditions
|  | ANNUAL INCENTIVE PLAN |  | ● Reward annual financial and individual performance |  | ● Target awards are established as a percentage of base salary ● The majority of each award’s target opportunity is based on the achievement of objective, pre-established goals related to the Company’s EPS and FCF performance
| LONG-TERM INCENTIVE AWARDS |  | ● Reward long-term Company performance ● Encourage focus on growing stockholder value ● Align management’s interests with stockholders’ interests ● Encourage retention of key management employees, stability, and continuity of leadership |  | ● Awards are provided through a combination of time-vesting RSUs and dollar-denominated PSUs ● Dollar-denominated PSUs are earned based on the achievement of objective, pre-established performance goals, including total shareholder return relative to certain comparable companies and the Company’s EPS performance ● RSUs are subject to a three-year vesting schedule; dollar-denominated PSUs that are earned based on performance cliff vest following the end of a three-year performance period
|  | BENEFITS |  | ● Attract and retain strong executive talent ● Provide basic financial stability |  | ● Participation in health, welfare, and retirement benefit plans, generally on the same terms as all other full-time employees of the Company

While base salaries, together with health, welfare, and retirement benefits, are designed to provide basic compensation and financial stability, the purpose of annual incentive compensation is primarily to encourage the Company’s executive officers to focus on the execution of the Company’s business strategy and plan for the current year. Long-term incentives, granted in the form of RSUs and PSUs, are designed to:

● | align executive officers’ interests with those of stockholders;
● | incentivize them to attain longer-term Company performance goals; and
● | encourage them to remain with the Company.

Unlike annual incentive compensation, which, as discussed below, tends to focus on more current Company and individual performance, long-term incentives focus on sustained results and growing stockholder value.

Relative Size of Major Compensation Elements

The combination of base salary, annual incentive awards, and long-term incentive awards is referred to as the “total direct compensation.” In setting executive officer compensation, the Committee considers the aggregate compensation payable to the executive, assuming target performance is achieved, as well as the weighting of each compensation component. The Committee seeks to achieve the appropriate balance between short- and long-term cash compensation and incentives for the achievement of both annual and long-term financial and non-financial objectives.

Allocation Among Compensation Elements

For 2024, the portion of the Chief Executive Officer’s and the average of each of the other Named Executive Officers’ total target direct compensation (for annual incentive awards, assuming target performance was achieved, and, for annual equity awards, based on grant date values at target) that was variable and at-risk is illustrated as follows:

Total Target Compensation Mix

“Average of Other Named Executive Officers” is based on an average of the respective compensation of Messrs. George and McKenna and Mses. Shaeff and Howell.

Because the value that a Named Executive Officer may receive with respect to RSUs will depend on the performance of the Company’s Common Stock, and therefore is variable, we have included these awards as an element of “Variable Pay” in the charts above.

Base Salary

The Committee determines base salary for our executive officers after considering several factors, including the executive’s individual experience, performance, and individual skills. Only after weighing these factors does the Committee consider peer group and/or survey data. The Committee uses executive officers’ performance assessments, Company performance, peer group and other survey data, as described above, and its own analysis of the executive officer’s individual performance to determine each executive’s base salary at least annually. Following its review of peer group and market data and the other factors described above, and taking into account the Company’s strong performance, on December 6, 2023, the Committee approved an increase in each Named Executive Officer’s base salary as set forth in the table below, effective January 1, 2024. The Committee believes that these increases were appropriate to reward the Named Executive Officers and bring their base salaries more in line with the market.

Named Executive Officer |  | 2024 Base Salary $ |  | 2023 Base Salary $
Brian Lane |  | 1,100,000 |  | 1,002,000
William George |  | 750,000 |  | 633,000

Allocation Among Compensation Elements

Annual Incentive Plan

The Named Executive Officers are eligible to participate in a cash-based annual incentive plan and receive incentive bonuses based on actual performance against key business and individual goals.

The annual incentive plan consists of two distinct components: a corporate financial performance component and an individual performance component. In 2024, consistent with previous years, the corporate financial performance component of the annual incentive plan rewarded the achievement of EPS and FCF goals (together, the “Corporate Financial Incentive”). The Committee believes that EPS remains an important metric for the Company because it encourages a focus on profitability. The Committee continued the use of FCF as a metric under the annual incentive plan because it incentivizes management’s focus on increasing the Company’s cash flow. The second, smaller, component of the annual incentive plan rewarded the achievement of specified individual performance goals (the “Individual Performance Incentive”).

Each year, the Committee determines the threshold, target, and maximum incentive opportunities for the Company’s executive officers, as a percentage of the executive’s base salary. To determine these base salary percentages for each Named Executive Officer for 2024, in addition to historical and projected Company financial performance, the Committee considered the Named Executive Officer’s historical annual incentive levels and the degree to which a Named Executive Officer’s efforts and job function were expected to influence and contribute to the Company’s financial performance. After assigning threshold, target, and maximum base salary percentages for each Named Executive Officer, the Committee then used peer group and other survey data, as described above, to assess the reasonableness of such assigned levels. Target annual incentive opportunities for the Named Executive Officers for 2024 are summarized in the table below, which were unchanged as compared to 2023 targets:

|  | Target Annual Incentive Opportunity as a Percent of Base Salary
Named Executive Officer |  | Target Corporate Financial Incentive |  |  | Target Individual Performance Incentive |  |  | Total Target Incentive Opportunity |
Brian Lane |  |  | 110 | % |  |  | 10 | % |  |  | 120 | %
William George |  |  | 90 | % |  |  | 10 | % |  |  | 100 | %
Trent McKenna |  |  | 90 | % |  |  | 10 | % |  |  | 100 | %
Laura Howell |  |  | 65 | % |  |  | 10 | % |  |  | 75 | %
Julie Shaeff |  |  | 65 | % |  |  | 10 | % |  |  | 75 | %

For the Corporate Financial Incentive, annual incentive opportunities were allocated 70% to the EPS portion and 30% to the FCF portion. For each metric, each Named Executive Officer had a threshold opportunity of 40% of his or her target annual incentive opportunity and a maximum annual incentive opportunity of 200% of his or her target annual incentive opportunity.

Corporate Financial Incentive Criteria

At the beginning of each year, the Committee sets a threshold, target, and maximum performance level for each corporate performance goal for purposes of the Corporate Financial Incentive component of the annual incentive plan. For each of the Named Executive Officers for 2024, consistent with prior years, the EPS portion of the Corporate Financial Incentive represented 70% of the total Corporate Financial Incentive opportunity, and the FCF portion of the Corporate Financial Incentive represented 30% of the total Corporate Financial Incentive opportunity. If neither the EPS nor FCF thresholds were met, then no portion of the Corporate Financial Incentive would be paid. If only one of the EPS or FCF thresholds were met, then only that portion of the Corporate Financial Incentive would be paid.

In setting the EPS and FCF threshold, target, and maximum performance levels, the Committee reviews management’s recommendations and then considers the Company’s historical financial performance as well as projections for the industry and industry historical financial performance and projections. The Committee sets EPS and FCF at levels that it considers aggressive but attainable with the intention that the Named Executive Officers will be encouraged to strive for continued improvement in Company performance, ultimately benefiting the Company’s stockholders, and to continue those efforts even after the EPS and/or FCF threshold performance levels have been achieved. The Committee believes that the added value that results from the Company’s achievement of EPS and/or FCF goals above the threshold performance levels to the Company and its stockholders is sufficient to justify the proportionate increases in amounts paid to the Named Executive Officers for achievement above threshold performance levels.

Allocation Among Compensation Elements

The threshold, target, and maximum performance levels for each of the corporate performance goals for 2024 annual incentives were as set forth in the table below. For performance between threshold, target, and maximum performance levels, the amount that is earned is determined on a straight-line basis.

2024 Corporate Financial Incentive Goals

EPS |  | Threshold |  | $6.30 |  |
|  | Target |  | $9.00 |  |
|  | Max |  | $11.70 |  |
FCF |  | Threshold |  | $150.5M |  |
|  | Target |  | $215.0M |  |
|  | Max |  | $279.5M |  |

For purposes of the annual incentive plan and consistent with previous years, (i) EPS was calculated from the Company’s audited financial statements for the year ended December 31, 2024 in accordance with U.S. generally accepted accounting principles, except that it did not take into account: (A) goodwill impairment; (B) write-off of debt costs; (C) restructuring charges; (D) any cumulative effect of a change in accounting principles; or (E) any other unusual or non-recurring items as determined by the Committee; and (ii) FCF was calculated by excluding: (A) certain unusual items, as determined by the Committee; and (B) certain items related to acquisitions or sales of businesses, including less customary capital expenditures plus the proceeds from asset sales. FCF is defined as cash flow from operating activities less customary capital expenditures, plus the proceeds from asset sales.

In 2024, the Committee did not make any adjustments to EPS or FCF for purposes of determining levels of achievement under the annual incentive plans. For a further discussion of how we calculate EPS and FCF, see the “Liquidity and Capital Resources” section and Note 14 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2024.

The Company’s EPS and FCF for calculating incentive compensation achievement levels for 2024 were $14.60 and $743.5 million, respectively. The amounts earned by each of the Named Executive Officers in respect of the Corporate Financial Incentive under the annual incentive plan for 2024 are set forth in the table below.

Individual Performance Incentive

In addition to, and independent from, the Corporate Financial Incentive portion of the annual incentive plan, for 2024 each Named Executive Officer was eligible to receive the Individual Performance Incentive, which is annual incentive compensation based on the executive’s achievement of individual performance goals related to the Company’s business and strategy.

At the beginning of 2024, each Named Executive Officer, including the Chief Executive Officer, identified individual performance goals for the upcoming year. Each Named Executive Officer’s individual performance goals were discussed and identified in consultation with (i) the Chief Executive Officer, in the case of Messrs. George and McKenna and Ms. Howell, (ii) the Chief Financial Officer, in the case of Ms. Shaeff, and (iii) the Committee, in the case of Mr. Lane. These goals varied depending on the roles and responsibilities for each Named Executive Officer. For 2024, specific goals for each Named Executive Officer included:

Executive | 2024 Individual Performance Goals
Brian Lane |  |  |  | Accomplish operational goals related to strategic, company-wide development
|  |  |  | Advance strategic succession planning initiatives
|  |  |  | Improve Company-wide employee safety measure(1)
|  |  |  | Achieve Company-wide talent goals
William George |  |  |  | Advance strategic acquisition and succession planning initiatives
|  |  |  | Improve Company-wide employee safety measure(1)
Trent McKenna |  |  |  | Accomplish enterprise strategy, professional development, and succession planning goals
|  |  |  | Advance strategic service growth initiatives
|  |  |  | Improve Company-wide employee safety measure(1)
|  |  |  | Achieve Company-wide talent goals
Laura Howell |  |  |  | Accomplish cybersecurity strategy priorities
|  |  |  | Ensure success of additional sustainability initiative priorities
|  |  |  | Improve Company-wide employee safety measure(1)
|  |  |  | Achieve Company-wide talent goals
Julie Shaeff |  |  |  | Complete 2024 target implementations for ERP strategy
|  |  |  | Accomplish certain professional development goals
|  |  |  | Improve Company-wide employee safety measure(1)

(1) | The Company-wide employee safety measure tracks the OSHA Recordable Incident Rate (“ORIR”), which is a nationally-recognized metric that tracks the number of employees per 100 full-time employees that have been involved in a recordable work-related injury or illness. In addition to the ORIR performance metric, the Company’s executive officers are required to attend safety training classes on an annual basis. No amount would be payable to the Named Executive Officers in respect of this safety measure if there was a work-related fatality of a Company employee during the year or if a Named Executive Officer does not attend the required safety classes. In 2024, the Company did have a work-related fatality, and no safety component credit related to the Individual Performance Incentive was obtained in 2024 as a result.

Compensation Discussion and Analysis

Allocation Among Compensation Elements

Each of the Named Executive Officers’ individual performance goals for 2024 were quantifiable and were generally composed of four levels of attainment: Minimum (25% attainment), Meets (50% attainment), Exceeds (75% attainment) and Significantly Exceeds (100% attainment). The goals were measured on a scale of 0-200% and were weighted to reflect each goal’s strategic importance.

The Chief Executive Officer and/or the General Counsel presented a summary evaluation of the level of achievement of these goals for each Named Executive Officer (other than himself or herself) to the Committee following the end of the year. In addition, each Named Executive Officer (other than Mr. Lane) received performance feedback from his or her direct supervisor throughout the year and a formal performance review at the end of the year, at which time the Named Executive Officer and his or her direct supervisor evaluated the Named Executive Officer’s satisfaction of his or her individual performance goals.

In executive session, the Committee reviewed and discussed its evaluation of Mr. Lane’s performance over the past year and the performance summaries for each other Named Executive Officer. The Committee also considered significant individual contributions beyond the pre-established goals and each executive’s overall effectiveness. Based on its evaluation of these factors, the Committee then determined the Named Executive Officer’s individual performance score. For 2024, the individual performance scores and the Individual Performance Incentive for each of the Named Executive Officers are set forth below:

2024 INDIVIDUAL PERFORMANCE INCENTIVE DETERMINATION

|  |  |  |  | Individual Performance Incentive Opportunity (As a % of Base Salary) |  |  |  |  | Individual Performance Incentive
Named Executive Officer |  | Base Salary $ |  |  | Threshold |  |  | Target |  |  | Maximum |  |  | Individual Performance Score |  |  | (As a % of Base Salary) |  |  | (In Dollars) $
Brian Lane |  |  | 1,100,000 |  |  |  | 5 | % |  |  | 10 | % |  |  | 20 | % |  |  | 110.0 | % |  |  | 11.0 | % |  |  | 121,000

Trent McKenna |  |  | 575,000 |  |  |  | 5 | % |  |  | 10 | % |  |  | 20 | % |  |  | 61.5 | % |  |  | 6.15 | % |  |  | 35,363
Laura Howell |  |  | 475,000 |  |  |  | 5 | % |  |  | 10 | % |  |  | 20 | % |  |  | 140.0 | % |  |  | 14.0 | % |  |  | 66,500
Julie Shaeff |  |  | 400,000 |  |  |  | 5 | % |  |  | 10 | % |  |  | 20 | % |  |  | 165.0 | % |  |  | 16.5 | % |  |  | 66,000

The Committee believes that corporate financial measures such as EPS and FCF, when taken together with an additional component to reflect individual achievement, are appropriate measures for determining annual incentive compensation. This two-part framework provided the Named Executive Officers with incentives to both achieve key Company financial goals and sustain long-term growth for the Company and also maintains the Committee’s flexibility to reward outstanding individual performance.

Long-Term Incentives

In 2024, LTI grants made to the Named Executive Officers consisted of RSUs and PSUs, the latter of which are denominated in dollar amounts but, once earned, are settled in shares of Common Stock based on the market value of the Common Stock following the end of the applicable performance period. The Committee designs the components and weightings of LTI awards to encourage the achievement of key performance goals and retention and also to balance the performance metrics utilized among the Company’s performance relative to certain comparable companies, the Company’s ongoing profitability, and the performance of the Common Stock. The Committee believes that these awards promote a long-term view and further align the executive officers’ interests with those of our stockholders.

From 2012 through 2018, the Company’s executive officers were generally granted PSUs, RSUs, and stock options on an annual basis. The Committee modified the structure for LTI awards in March 2019 by removing stock options from annual LTI grants and rebalancing the awards so that 50% of the LTI grant was in the form of RSUs and 50% was in the form of PSUs, based on grant date value and, for PSUs, assuming target performance is achieved. This decision was based, in part, on input from its compensation consultant, and was the first significant structural change since the previous LTI structure was adopted in 2012. The Committee believed that removing stock options and allocating more value to the PSU and RSU awards better aligned the Company’s compensation program with peer and broader market practices. The mix provides a balanced approach to long-term retention through the use of RSU awards while still including a heavy emphasis on performance-based awards through the use of PSUs. The Company’s annual LTI grants for the Named Executive Officers in March 2024 followed this 50% RSU and 50% PSU structure.

Allocation Among Compensation Elements

The Committee believes that LTI compensation should be correlated with salary and short-term incentive compensation. As such, the Committee uses a percentage of each executive officer’s base salary to determine the total dollar amount of the LTI compensation award to be granted to that executive each year, based on grant date values and, for PSUs, assuming target performance is achieved. The Committee determines these percentage levels by analyzing each executive officer’s tenure, responsibilities, and professional experience, recommendations from its compensation consultant based on peer group and other survey data, as described above, and the executive officer’s historical annual LTI compensation levels. For 2024, the following percentage of base salary was used for the Named Executive Officers to determine the grant date value of annual LTI awards: Mr. Lane, 410% of base salary; Mr. George, 190% of base salary; Mr. McKenna, 175% of base salary; Ms. Howell, 145% of base salary; and Ms. Shaeff, 105% of base salary. Following its review of peer group and market data and the other factors described above, and taking into account the Company’s strong performance, on December 6, 2023, the Committee approved an increase in each Named Executive Officer’s annual LTI awards, as a percentage of his or her base salary, as set forth in the table below. The Committee believes that these increases were appropriate to reward the Named Executive Officers, further align their interest with our stockholders, and bring their LTI awards and compensation generally more in line with the market.

Named Executive Officer |  | 2024 LTI Percentage |  | 2023 LTI Percentage |
Brian Lane |  | 410 | % | 325 | %
William George |  | 190 | % | 170 | %
Trent McKenna |  | 175 | % | 145 | %
Laura Howell |  | 145 | % | 100 | %
Julie Shaeff |  | 105 | % | 85 | %

Once each executive officer’s total grant date value is determined, the number of RSUs and the value of PSUs is determined. The number of RSUs granted is determined by dividing the total dollar amount of the RSUs to be granted by the closing price of the Company’s stock on the date of grant, and rounding down to the nearest full RSU. PSUs are denominated in dollars.

As an illustration, Mr. Lane’s 2024 award of LTI compensation was calculated as follows:

Total Amount of Award: 410% of base salary of $1,100,000 equals $4,510,000.

RSUs Awarded: 50% of $4,510,000 equals $2,255,000 in value of RSUs. $2,255,000 divided by $314.31 (the closing price of the Common Stock on the date of grant) equals 7,174 RSUs.

PSUs Awarded: 50% of $4,510,000 equals $2,255,000 in value of PSUs (dollar-denominated, assuming target performance).

The table below sets forth the 2024 annual LTI awards for each of the Named Executive Officers:

Named Executive Officer |  | Base Salary $ |  | Salary Percentage For Calculating Plan Awards |  | Number of RSUs Awarded |  | Dollar Value of PSUs Awarded (At Target) $ |  | Value of Awards Under Plan (At Target) $
Brian Lane |  | 1,100,000 |  | 410 | % | 7,174 |  | 2,255,000 |  | 4,510,000
William George |  | 750,000 |  | 190 | % | 2,266 |  | 712,500 |  | 1,425,000
Trent McKenna |  | 575,000 |  | 175 | % | 1,600 |  | 503,125 |  | 1,006,250
Laura Howell |  | 475,000 |  | 145 | % | 1,095 |  | 344,375 |  | 688,750
Julie Shaeff |  | 400,000 |  | 105 | % | 668 |  | 210,000 |  | 420,000

PSU DESIGN

Upon vesting, PSUs will be settled in shares of Common Stock, with the number of such shares determined by dividing the dollar value of vested PSUs (which may be up to 200% of the original dollar value of such PSUs) by the market value of the Common Stock following the end of the applicable three-year performance period. PSUs are earned based on the level of achievement of the two goals set forth in the table below, both of which are measured on an annual basis over a three-year performance period, and earned PSUs vest in full upon determination of the level of achievement of the performance metrics by the Committee following the end of the applicable three-year performance period, generally subject to continued employment through the end of the three-year performance period.

Performance Measure |  | Measurement |  | Percentage of Performance Award Subject to Measure
Earnings Per Share |  | ● Company’s actual EPS performance relative to pre-established EPS performance goals |  | ● 50%
Relative Total Shareholder Return |  | ● Company’s performance relative to comparable companies* |  | ● 50%

* | For purposes of measuring the Company’s relative total shareholder return for awards granted in 2024, the identified group of comparable companies consists of: Matrix Service Company; Primoris Services Corporation; Tutor Perini Corporation; Stantec Inc.; Dycom Industries Inc.; MasTec, Inc.; Sterling Infrastructure, Inc.; EMCOR Group Inc.; MYR Group, Inc.; Quanta Services, Inc.; Tetra Tech Inc.; Great Lakes Dredge & Dock Corporation; Granite Construction Incorporated; Limbach Holdings, Inc.; and APi Group Corporation. Based on industry analysis and feedback from financial analysts, the Company believes these companies are the most likely to compete with the Company for investment by institutional investors. This group of comparable companies is not used for benchmarking the compensation of the Named Executive Officers.

EPS

The EPS measure compares the Company’s actual EPS performance against its pre-established EPS performance goals over a three-year performance period. For this purpose, EPS is determined and calculated as described under “Annual Incentive Plan” above. For each year in the performance period, the Company’s actual EPS performance is compared against these EPS goals and expressed as a percentage. The EPS percentages for each of the three years in the performance period are then averaged together to determine the final level of EPS achievement upon which the payout, if any, will be earned.

Relative Total Shareholder Return (“TSR”)

The relative TSR measure compares the Company’s TSR to the TSR of a specified group of comparable companies, and payouts are determined by the Company’s rank relative to others in the group. For each year in the three-year performance period, TSR is calculated by determining the difference between the average closing price of a company’s common stock during the first 30 consecutive days of the year and the last 30 consecutive days of the year. The calculation assumes that dividends are reinvested in additional shares. The Company’s TSR is then compared against the TSR for other companies in the group and assigned a percentile ranking. The Company’s TSR percentile ranking for each of the three years in the performance period are then averaged together to determine the final percentile ranking upon which the payout, if any, will be earned.

The following chart shows the range of potential settlement of the PSUs based on the two performance measures, as a percentage of the target amount. The number of PSUs that may be earned ranges from 0% to 200% of the target award amount.

|  | Relative TSR |  | EPS
Performance Level |  |  | Percentage of Target Earned |  |  | Performance Measure |  |  | Percentage of Target Earned |  |  | Performance Measure
Maximum |  |  | 200 | % |  | 75th Percentile or Above |  |  | 200 | % |  | Over 120% of Target
Target |  |  | 100 | % |  | 50th Percentile |  |  | 100 | % |  | 100% of Target
Threshold |  |  | 50 | % |  | 25th Percentile |  |  | 25 | % |  | 70% of Target
Below Threshold |  |  | 0 | % |  | Below 25th Percentile |  |  | 0 | % |  | Below 70% of Target

PSU AWARDS WITH PERFORMANCE PERIOD ENDING IN 2024

PSU awards granted in 2022 with a 2022-2024 performance period were settled in early 2025. The following table shows the EPS and TSR levels achieved over such awards’ three-year performance period and the payout factor for these awards.

|  | 2022 |  |  | 2023 |  |  | 2024 |  |  | 3-Year Average |  |  | Payout Factor (% of Target) |
EPS |  |  | 117 | % |  |  | 158 | % |  |  | 162 | % |  |  | 146 | % |  |  | 200 | %
TSR |  |  | 93 | % |  |  | 87 | % |  |  | 73 | % |  |  | 84 | % |  |  | 200 | %

RULE OF 75

The “Rule of 75” provides that if an executive officer retires from the Company at a time when the sum of his or her age and his or her years of service at the Company is greater than or equal to 75, then upon the executive’s retirement, the executive will generally have been deemed to have satisfied the continuous employment requirement for any equity award to vest (unless the award provides otherwise). Pursuant to the Rule of 75, all performance-based equity awards will continue to be earned only if the applicable performance measures are satisfied and only up to a maximum of target value, but the requirement that the executive be employed by the Company at the time of vesting based on performance will be deemed to be satisfied. As of December 31, 2024, Messrs. Lane and George and Ms. Shaeff satisfied the Rule of 75.

Health and Retirement Benefits

The Company’s health and retirement plans include medical, dental, life, disability and accidental death and dismemberment coverage, and eligibility to participate in the Company’s 401(k) retirement plan. The Company’s benefit programs are designed to be competitive with those of other similarly-sized and -situated companies. The plans offered to the Company’s executive officers are broad-based plans available to all full-time employees. Under the Company’s 401(k) retirement plan, the Company matches an employee’s pre-tax contributions to the plan at a rate of 50% of up to 5% of an employee’s eligible pay or up to the maximum allowed contribution pursuant to the Internal Revenue Code of 1986, as amended (the “Code”).

Perquisites

The Company generally does not provide perquisites to its executive officers that are not provided to other employees. However, the Company does provide increased levels of disability and life insurance coverage that are only available to executive officers of the Company. The Company pays these increased premiums on behalf of the executive officers.

Change in Control and Severance Benefits

Change in Control and Severance Benefits

The Named Executive Officers and other members of senior management serve as at-will employees of the Company without any guaranteed period of employment. However, the Committee believes that an executive severance policy paired with change in control agreements provide appropriate protections to attract and retain qualified and talented individuals to serve as the Company’s executive officers, permit the Company’s executive officers to focus fully on improving the Company’s operations and long-term success, and protect stockholder value by providing continuity of management during any transition period. The severance and change in control benefits are intended to be set at market-competitive levels and help ensure that the Company can attract and retain talented executive officers. These benefits also help ensure that executive officers remain focused on maximizing stockholder value in the context of an actual or potential transaction that might result in the loss or the diminution of their current positions. The Company believes that these benefits are reasonable and ultimately benefit stockholders. The executive severance policy and change in control agreements are more fully described below under “Potential Payments Upon Termination or Change in Control.”

Stock Ownership Requirements

The Company’s stock ownership requirements provide that within three years of being appointed as an executive officer, or being promoted to such a position, an executive is required to beneficially own Common Stock, taking into account all outstanding vested and unvested stock options, RSUs, PSUs, and shares of stock, having a market value or cost basis, whichever is higher, equal to at least the following multiple of his or her base salary (for purposes of determining an executive’s stock ownership multiple, if an executive holds more than one title subject to a stock ownership requirement, then the title with the higher multiple will apply to such executive):

LEVEL | BASE SALARY MULTIPLE |
Chief Executive Officer |  |
Chief Operating Officer |  |
Chief Financial Officer |  |
General Counsel |  |
Senior Vice President |  |
Chief Accounting Officer |  |
Regional Vice President |  |

For purposes of calculating the above multiple, the actual compensation expense incurred by the Company related to the equity award is used only if it is greater than the current market value of the Common Stock subject to the equity award. In March 2024, the Board revised the Company’s Governance Standards to add ownership requirements for all Regional Vice Presidents, as set forth above. As of December 31, 2024, each of our executive officers was in compliance with the stock ownership requirements.

Executive Compensation Recovery, or “Clawback,” Policy

The Company’s executive compensation recovery, or “clawback,” policy provides that, to the extent permitted by applicable law, the Board may seek to recoup—or “claw back”—any cash compensation paid to executive officers and certain other employees identified by the Board where the payment was predicated upon the achievement of certain financial results that were satisfied based upon such individual’s intentional, fraudulent, or illegal conduct. The Board has the sole discretion to determine whether an individual’s conduct has or has not met any particular standard of conduct. The Board may, in its sole discretion after considering the best interests of the Company, determine not to recover such payment. In the event that a restatement of the Company’s financial statements is required, the Company will seek to recover any compensation received by the Chief Executive Officer and Chief Financial Officer that is required to be recovered by Section 304 of the Sarbanes-Oxley Act of 2002. In 2023, we expanded our clawback policy to address the recovery of erroneously-awarded incentive compensation in compliance with the requirements of the Dodd-Frank Act, final SEC rules, and applicable listing standards by adopting an additional policy, which additional policy was filed as an exhibit to our Annual Report on Form 10-K, commencing with the Annual Report on Form 10-K for the year ended December 31, 2023.

Anti-Hedging/Pledging Policy

Anti-Hedging/Pledging Policy

Our Insider Trading Window Policy prohibits our directors, executive officers, and other employees from, among other things, engaging in hedging or monetization transactions, including through the use of financial instruments such as prepaid variable forwards, equity swaps, collars, and exchange funds, that may permit them to continue to own Company stock, but without the full risks and rewards of ownership. No categories of hedging transactions are specifically permitted by this policy. Our Insider Trading Window Policy also prohibits our directors, executive officers, and other employees from holding Company securities in a margin account or otherwise pledging Company securities as collateral for a loan.

Equity Award Policy and Practices

In response to Item 402(x)(1) of Regulation S-K, we generally do not currently grant new awards of stock options, stock appreciation rights or similar option-like instruments. Accordingly, we have no specific policy or practice on the timing of awards of such options in relation to our disclosure of material nonpublic information. In the event we determine to grant new awards of such options in the future, we will evaluate the appropriate steps to take in relation to the foregoing. For fiscal year ended December 31, 2024, we did not grant stock options, stock appreciation rights or similar option-like instruments to any Named Executive Officer.

Risk Considerations in our Compensation Policies

The Committee regularly reviews our various compensation programs and has concluded that they do not create risks that are reasonably likely to have a material adverse effect on the Company or our stockholders. In reaching this conclusion, the Committee considered the following: (i) the use of balanced performance targets; (ii) the Company’s “clawback” policies; (iii) the Company’s stock ownership requirements; (iv) the use of EPS performance metrics that are uniformly applied to all executive officers; (v) a three-year vesting period for LTI compensation; and (vi) the Company’s anti-hedging/pledging policy.

Impact of Accounting and Tax Treatment on Compensation

Section 162(m) of the Code (“Section 162(m)”) generally disallows a tax deduction for any publicly-held corporation for individual compensation exceeding $1 million in any taxable year payable to certain executive officers, subject to certain grandfathering rules for compensation arrangements in effect on November 2, 2017 and not materially modified thereafter. The Committee believes that its primary responsibility is to provide a compensation program that attracts, retains, and rewards the executive officers and other key employees that are important to the Company’s success. Accordingly, the Committee has authorized and will continue to authorize compensation payments that are limited, in full or in part, as to tax deductibility.

The Committee regularly considers the accounting implications of significant compensation decisions, especially in connection with decisions that relate to our equity plans and programs. If accounting standards change, the Company may revise certain programs to appropriately align accounting expenses of our equity awards with our overall executive compensation philosophy and objectives.

Summary of Executive Compensation

Summary Compensation Table

(1) | Reflects the aggregate grant date fair value of PSUs and RSUs granted to the Named Executive Officers in the applicable year. The aggregate grant date fair value of these awards was computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. See Note 15 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the years ended December 31, 2022, December 31, 2023, and December 31, 2024, as applicable, for a discussion of the relevant assumptions used in calculating the value of these awards. For these purposes, the grant date fair value of the PSUs is computed based on performance at the target level, the probable outcome of the performance conditions as of the date of grant, and the grant date fair value of RSUs is equal to the number of RSUs granted multiplied by the closing stock price of the Common Stock on the date of grant. The aggregate grant date fair value will likely vary from the actual amount the Named Executive Officers receive in respect of the PSUs and RSUs, based on a number of factors, including stock price fluctuations and variances from valuation assumptions.
| The PSUs are denominated in dollars and, to the extent they are earned and vest, will be settled in Common Stock based on the market value of the Common Stock following the applicable performance period. PSUs are earned if, and to the degree that, the Company meets certain objective, pre-established performance goals relating to total shareholder return compared to a specified group of comparable companies and EPS performance each year over a three-year performance period and generally vest only if the Named Executive Officer remains employed by the Company through such performance period. The aggregate grant date fair value of the PSUs granted during 2024, assuming achievement of the highest level of performance, was $4,510,000 for Mr. Lane; $1,425,000 for Mr. George; $1,006,250 for Mr. McKenna; $688,750 for Ms. Howell; and $420,000 for Ms. Shaeff. The aggregate grant date fair value of the PSUs granted during 2023, assuming achievement of the highest level of performance, was $3,256,500 for Mr. Lane; $1,076,100 for Mr. George; $733,700 for Mr. McKenna; $425,000 for Ms. Howell; and $311,950 for Ms. Shaeff. The aggregate grant date fair value of the PSUs granted during 2022, assuming achievement of the highest level of performance, was $2,613,600 for Mr. Lane; $880,000 for Mr. George; $572,000 for Mr. McKenna; $280,000 for Ms. Howell; and $266,400 for Ms. Shaeff.
| The RSUs are scheduled to vest over three years, generally subject to the Named Executive Officer’s continued employment with the Company on the applicable vesting date.
(2) | Reflects a one-time payment for each Named Executive Officer equal to 10% of such Named Executive Officer’s above-listed 2022 base salary and approved by the Committee in March 2022 to reward efforts from prior years to obtain tax credits for the Company’s research and development efforts given that the Committee decided that positive impacts to EPS and FCF would be excluded from annual incentive compensation calculations.
(3) | Reflects annual incentive plan awards earned in the applicable year based upon the satisfaction of specified performance goals. To avoid duplication, the 2022 amounts specifically exclude the one-time bonus payments referenced above. For more information on the annual incentive compensation paid to Named Executive Officers for 2024, see the subsection of the CD&A titled “Annual Incentive Plan.”

(1) | Reflects amounts payable under 2024 annual incentive plan awards based on individual and Company performance for 2024, which are described in greater detail in the subsection of the CD&A titled “Annual Incentive Plan.” Goals under the Individual Performance Incentive component of annual incentive plan awards are measured on a scale of 0% - 200% and do not have a threshold payment level. For purposes of this table, it is assumed that each Named Executive Officer realizes (a) 40% of the Corporate Financial Incentive at threshold, 100% at target, and 200% at maximum, and (b) 50% of the Individual Performance Incentive at threshold, 100% at target, and 200% at maximum.
(2) | Reflects amounts payable under dollar-denominated PSUs granted as part of each Named Executive Officer’s 2024 LTI awards based on the satisfaction of Company performance goals applicable to the PSUs. The threshold amount is calculated based on the minimum amount that a Named Executive Officer could earn with respect to the PSUs, calculated as if the EPS performance goal were achieved at the minimum level of performance that would result in a portion of the PSUs being earned and as if the minimum level of performance to earn PSUs based on the relative TSR performance goal were not achieved. For additional information about the PSU awards, see footnote 1 of the Summary Compensation Table and the subsection of the CD&A titled “Long-Term Incentives.”
(3) | Reflects RSUs granted as part of each Named Executive Officer’s 2024 annual LTI awards. For additional information about the RSU awards, see footnote 1 of the Summary Compensation Table and the subsection of the CD&A titled “Long-Term Incentives.”
(4) | Reflects the grant date fair value of LTI awards, computed in accordance with FASB ASC Topic 718, excluding the effect of estimated forfeitures. For the RSUs, the value is equal to the number of RSUs multiplied by the closing stock price of the Common Stock on the date of grant ($314.31). For the PSUs, the value is determined as the value at the grant date based on the probable outcome of the performance conditions. For a discussion of valuation assumptions, see Note 15 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024, and for the maximum value of these awards at grant, see footnote 1 to the Summary Compensation Table above.

(1) | No Named Executive Officer held any unexercisable options as of December 31, 2024.
(2) | Mr. Lane’s 19,638 unvested RSUs consist of 11,012 RSUs scheduled to vest on April 1st of 2025, 6,235 RSUs scheduled to vest on April 1st of 2026, and 2,391 RSUs scheduled to vest on April 1st of 2027, in each case, generally subject to his continued employment with the Company through the applicable vesting date.
| Mr. George’s 23,082 unvested RSUs consist of 3,634 RSUs scheduled to vest on April 1st of 2025, 8,334 RSUs scheduled to vest on December 1st of 2025, 2,026 RSUs scheduled to vest on April 1st of 2026, 8,333 RSUs scheduled to vest on December 1st of 2026, and 755 RSUs scheduled to vest on April 1st of 2027, in each case, generally subject to his continued employment with the Company through the applicable vesting date.
| Mr. McKenna’s 4,377 unvested RSUs consist of 2,444 RSUs scheduled to vest on April 1st of 2025, 1,400 RSUs scheduled to vest on April 1st of 2026, and 533 RSUs scheduled to vest on April 1st of 2027, in each case, generally subject to his continued employment with the Company through the applicable vesting date.
| Ms. Howell’s 2,610 unvested RSUs consist of 1,379 RSUs scheduled to vest on April 1st of 2025, 866 RSUs scheduled to vest on April 1st of 2026, and 365 RSUs scheduled to vest on April 1st of 2027, in each case, generally subject to her continued employment with the Company through the applicable vesting date.

| The number of units in the bottom most row of this column for each Named Executive Officer relates to the PSU awards granted for the 2022-2024 performance period. The three-year average performance payout factor for the EPS component of these awards was 200%. The three-year average performance payout factor for the relative TSR component of these awards was 200%. For purposes of this table, the number of units has been determined by dividing the cash value of the portion of the awards earned based on actual performance by $424.06, the closing price of a share of Common Stock on December 31, 2024. The actual number of shares that were delivered in respect of these awards was determined by dividing the cash value of the awards earned based on actual performance by $357.53, the closing price of a share of Common Stock on March 19, 2025, the date when the performance was determined by the Compensation and Human Capital Committee.
(3) | The market value is based on the closing price of a share of Common Stock ($424.06) as of December 31, 2024 for unvested RSUs, and is based on the actual dollar amount earned under the PSU awards for the 2022-2024 performance period, given that these awards are dollar-denominated awards.
(4) | The number of shares in this column relates to outstanding PSU awards for the 2023-2025 and 2024-2026 performance periods, with the PSU awards for the 2023-2025 performance period in the bottom most row of this column for each Named Executive Officer. The number of shares underlying PSU awards is determined by calculating the market value of shares of Common Stock underlying such PSU awards assuming maximum performance is achieved, as described in more detail in footnote 5 below, divided by the closing price of a share of Common Stock ($424.06) as of December 31, 2024. The actual number of shares that will be delivered in respect of outstanding PSU awards will depend on the performance achieved for the relevant performance periods and the market value of shares of Common Stock on the date of delivery.
(5) | PSU awards are denominated in dollar amounts and are settled by delivery of shares of Common Stock following the end of the applicable performance period. PSU awards are subject to both time-based and performance-based vesting and vest only to the extent that the relevant performance metrics are achieved during the applicable performance period. Thus, at any time prior to the end of the applicable performance period, the exact number of shares of Common Stock underlying unvested PSU awards is not readily identifiable. Instead, the Company has included the dollar value that a Named Executive Officer would earn under outstanding PSU awards for each of the 2023-2025 and 2024-2026 performance periods assuming achievement of maximum performance, with the dollar value for the 2023-2025 performance period in the bottom most row of this column for each Named Executive Officer.

(1) | The value realized on the exercise of stock options is the difference between (a) the price at which the shares of Common Stock were sold upon exercise of the stock option on the date of exercise (or, if inapplicable due to a cash exercise, the closing price of the Common Stock on the date of exercise), and (b) the exercise price of the option.
(2) | The value realized on the vesting of RSU awards is determined based on the average of the high and low price of the Common Stock on the vesting date.
(3) | Represents PSUs that were earned with respect to the 2021-2023 performance period and that were settled in early 2024. The value realized on the vesting of PSU awards is calculated based on the closing price of the Common Stock on March 20, 2024, the date when the performance was determined by the Compensation and Human Capital Committee.

Potential Payments Upon Termination or Change in Control

The Company maintains an Executive Severance Policy that covers the Named Executive Officers and other key employees and has entered into change in control agreements with each Named Executive Officer, as described below. Under the Executive Severance Policy, in addition to providing outplacement assistance of up to $50,000 and reimbursing former executive officers’ insurance premiums for continuing COBRA coverage under the Company’s policies for up to 12 months if they do not have insurance coverage available through another employer, the Company will pay a lump-sum amount equal to (i) the sum of the executive officer’s current base salary plus bonus (consisting of the greater of the average annual incentive plan bonus paid during the last three years or the annual incentive plan bonus for the year of termination of employment, determined following completion of the applicable performance period pursuant to the goals established for such bonus), times (ii) the applicable multiplier set forth below, if an executive officer’s employment is terminated by the Company without cause, and not due to death or disability:

● | Two times such amounts for the Chief Executive Officer or the President;
● | One and one-half times such amounts for the Chief Financial Officer, Chief Operating Officer, or an Executive Vice President;
● | One times such amounts for the Chief Accounting Officer, Chief Legal Officer or General Counsel, and certain specified Senior Vice Presidents; and
● | One-half times such amounts for any other employees who have been subject to reporting under Section 16 of the Exchange Act while employed by the Company or who have been otherwise designated by the Compensation and Human Capital Committee to participate in the plan, but not at a different participation level.

In the case of death or disability, the Executive Severance Policy provides for the Company’s payment of a one-time lump-sum amount equal to the executive’s annual base salary reduced by any benefits payable under Company-paid life or disability insurance policies. No amounts are paid under the policy on a voluntary termination of employment or a termination of employment by the Company for cause.

The change in control agreements with the Named Executive Officers provide severance benefits in connection with certain qualifying terminations following a change in control. Severance benefits under the change in control agreements are triggered in case of a termination of employment by the Company (or its successor) without cause or by the executive for good reason, in each case, within 12 months following the change in control event. The current change in control agreements with Messrs. Lane and George and Ms. Shaeff also provide for severance benefits if the executive resigns from the Company (with or without good reason) within 90 days following the change in control event. As we have previously disclosed, new change in control agreements entered into after February 2014 do not include this feature, and, as such, it is not included in either Mr. McKenna’s or Ms. Howell’s change in control agreement. In addition to reimbursement of the former executive officers’ insurance premiums for continuing COBRA coverage under the Company’s policies for up to 12 months if they do not have insurance coverage available through another employer, these agreements provide for the Company’s payment of a lump-sum amount equal to (i) the sum of the officer’s current base salary plus bonus (the greater of the average incentive plan bonus paid during the last three years or annual incentive plan bonus for the year of termination of employment, determined following completion of the applicable performance period pursuant to the goals established for such bonus), times (ii) the applicable multiplier set forth below, to the Named Executive Officers upon a qualifying termination of employment within 12 months following a change in control event:

● | Two times such amounts for Messrs. Lane, George, and McKenna; and
● | One times such amounts for Mses. Shaeff and Howell.

Under the change in control agreements, Messrs. Lane and George and Ms. Shaeff may be entitled to so-called golden parachute excise tax gross ups in connection with change in control payments in certain circumstances. The Company eliminated the practice of providing for gross-up payments in change in control or other agreements on a going-forward basis, starting in 2013.

Under the change in control agreements, unvested equity awards held by the Named Executive Officers vest in full upon a change in control, with PSUs vesting at target levels.

Regardless of the reason for termination, the Named Executive Officers must execute a release of claims and are subject to a one-year non-compete agreement in order to receive any severance benefits under the change in control agreements or Executive Severance Policy.

As described above, holders of outstanding equity awards who meet the age and service requirements under the “Rule of 75” will, upon the holder’s retirement, generally be deemed to have satisfied the continuous employment requirement for any equity award to vest, unless the equity award specifies otherwise. Pursuant to the Rule of 75, all performance-based equity awards will continue to be earned only if the applicable performance measures are satisfied and only up to a maximum of target value, but the requirement that the executive be employed by the Company at the time of vesting based on performance will be deemed to have been satisfied. As of December 31, 2024, Messrs. Lane and George and Ms. Shaeff satisfied the Rule of 75.

Potential Payments Upon Termination or Change in Control

Summary of Potential Payments

If Mr. Lane had retired on December 31, 2024, he would be deemed to have satisfied the continuous employment requirement for purposes of vesting in: (1) 19,638 RSUs, consisting of 11,012 RSUs scheduled to vest on April 1st of 2025, 6,235 RSUs scheduled to vest on April 1st of 2026, and 2,391 RSUs scheduled to vest on April 1st of 2027; and (2) if applicable performance measures are satisfied, PSUs granted in 2022 with a target value of $1,306,800, PSUs granted in 2023 with a target value of $1,628,250, and PSUs granted in 2024 with a target value of $2,255,000, each of which would vest in the year following the performance period, to the extent earned based on performance and only up to target value, on the date on which the performance is determined by the Compensation and Human Capital Committee.

If Mr. George had retired on December 31, 2024, he would be deemed to have satisfied the continuous employment requirement for purposes of vesting in: (1) 6,415 RSUs, consisting of 3,634 RSUs scheduled to vest on April 1st of 2025, 2,026 RSUs scheduled to vest on April 1st of 2026, and 755 RSUs scheduled to vest on April 1st of 2027; and (2) if applicable performance measures are satisfied, PSUs granted in 2022 with a target value of $440,000, PSUs granted in 2023 with a target value of $538,050, and PSUs granted in 2024 with a target value of $712,500, each of which would vest in the year following the performance period, to the extent earned based on performance and only up to target value, on the date on which the performance is determined by the Compensation and Human Capital Committee. Mr. George’s one-time grant of 25,000 RSUs in November 2023 does not include any “Rule of 75” vesting provisions and, as a result, 16,667 unvested RSUs would have been forfeited upon retirement on December 31, 2024.

If Ms. Shaeff had retired on December 31, 2024, she would be deemed to have satisfied the continuous employment requirement for purposes of vesting in: (1) 1,891 RSUs, consisting of 1,078 RSUs scheduled to vest on April 1st of 2025, 590 RSUs scheduled to vest on April 1st of 2026, and 223 RSUs scheduled to vest on April 1st of 2027; and (2) if applicable performance measures are satisfied, PSUs granted in 2022 with a target value of $133,200, PSUs granted in 2023 with a target value of $155,975, and PSUs granted in 2024 with a target value of $210,000, each of which would vest in the year following the performance period, to the extent earned based on performance and only up to target value, on the date on which the performance is determined by the Compensation and Human Capital Committee.

Summary of Potential Payments

The following table provides the lump-sum payments that would have been made to each Named Executive Officer if his or her employment had been terminated on December 31, 2024 by the Company without cause, or by reason of the Named Executive Officer’s death or disability, in each case, other than in connection with a change in control.

|  | For Cause ($) |  | Death(1) ($) |  | Disability(2) ($) |  | Without Cause(3) ($)
Brian Lane |  | 0 |  | 1,100,000 |  | 1,100,000 |  | 7,329,259

Laura Howell |  | 0 |  | 475,000 |  | 475,000 |  | 1,184,000
Julie Shaeff |  | 0 |  | 400,000 |  | 400,000 |  | 1,028,918

(1) | The Company maintains life insurance for each of the Named Executive Officers in an amount equal to the Named Executive Officer’s annual base salary, up to a maximum of $500,000. The death benefit contained in the Executive Severance Policy is paid net of insurance proceeds.
(2) | The Company maintains disability insurance for each of the Named Executive Officers in an amount equal to the Named Executive Officer’s annual base salary, up to a maximum of $500,000. The disability benefit contained in the Executive Severance Policy is paid net of insurance proceeds.
(3) | Consists of two times the sum of current base salary plus bonus (the greater of the average annual incentive plan bonus paid during the last three years or the annual incentive plan bonus for the year of termination of employment, determined following completion of the applicable performance period pursuant to the goals and objectives established for such bonus) for Mr. Lane; one and one-half times such amounts for Messrs. George and McKenna; and one times such amounts for Mses. Howell and Shaeff. In addition, the following amounts are included in the total for each executive as an estimate of one year of COBRA premium reimbursements payable by the Company to the Named Executive Officer over the 12-month period following termination: Mr. Lane—$22,259; Mr. George—$24,323; Mr. McKenna—$21,456; Ms. Howell—$0; and Ms. Shaeff—$17,918. These COBRA reimbursements would be made by the Company to the Named Executive Officer, and they would cease if the Named Executive Officer obtained other insurance coverage. In no event would these COBRA premium reimbursements be paid for more than 12 months. The total amount also reflects an estimate of $25,000 for outplacement services, which services are provided for in the Executive Severance Policy in an amount not to exceed $50,000.

(1) | Consists of two times the sum of current base salary plus bonus (the greater of the average incentive plan bonus paid during the last three years or the current annual incentive plan bonus for 2024) for Messrs. Lane, George, and McKenna and one times such amounts for Mses. Shaeff and Howell. The amount listed also includes payments made as reimbursements for COBRA premiums for a one-year period after the change in control event; these payments would be made as reimbursements by the Company to the Named Executive Officer, and would cease if the Named Executive Officer obtained other insurance coverage.
(2) | The value of the acceleration of unvested time-based RSUs is determined by multiplying the number of shares underlying the award by the closing price of a share of Common Stock on December 31, 2024 ($424.06). The value of PSUs for the 2022-2024, 2023-2025, and 2024-2026 performance periods has been determined by assuming that the awards vest and are paid out at target levels of performance.
(3) | Reflects the estimated amount of the gross-up for excise taxes imposed under Section 4999 of the Code.

(1) | Includes 29,936 stock options and 157,412 shares of time-vested restricted stock units that have been granted but remain unvested as of December 31, 2024, determined by treating each share underlying a stock option as one share and each share underlying such time-vested restricted stock unit awards as two shares. Additionally, 96,498 shares of Common Stock may be issued upon the achievement of certain performance conditions under outstanding PSU awards. The PSU awards are dollar-denominated and paid in shares based on the market value of the shares following the end of the performance period for such awards; for purposes of this table, the number of shares underlying outstanding PSU awards has been estimated based on current estimated achievement of the performance conditions applicable to the awards and the closing market price of the Company’s stock on December 31, 2024. The Company has no other securities to be issued upon exercise of outstanding options, warrants, or rights. For additional information regarding our equity plans, see Note 14 to our consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024.
(2) | Restricted stock units and PSUs are not factored into this average.
(3) | Reflects shares that are part of a fungible share plan, which means that each share granted that is not an option or a SAR is counted against the plan as two (2.0) shares.

Ratio of Chief Executive Officer Compensation to Median Company Employee Compensation

As required by SEC rules, we are providing the following information about the relationship of the annual total compensation of our employees and the annual total compensation of our Chief Executive Officer. This pay ratio is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K. Because the SEC rules for identifying the median compensated employee and calculating the pay ratio based on that employee’s annual total compensation allow companies to adopt a variety of methodologies, to apply certain exclusions, and to make reasonable estimates and assumptions that reflect their compensation practices, the pay ratio reported by other companies may not be comparable to the pay ratio reported below.

For 2024, our last completed fiscal year:

● | The median of the annual total compensation of all employees of the Company (other than our Chief Executive Officer) was $59,611; and
● | The annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table included elsewhere in this proxy statement, was $8,176,738.

| Based on this information, for 2024, the ratio of annual total compensation of our Chief Executive Officer to the median of the annual total compensation of all other employees is estimated to be 137.2 to 1.

As permitted by SEC rules, in determining this ratio, we used the same “median employee” that we used for purposes of calculating our pay ratio for 2023 because there have been no changes in our employee population or employee compensation arrangements that we reasonably believe would result in a significant change to our pay ratio disclosure. In making this determination, we took into account changes in our employee population and compensation arrangements relating to our 2023 acquisitions of Eldeco, Inc. and DECCO, Inc., but not any changes relating to our 2024 acquisitions of J & S Mechanical Contractors, Inc., Summit Industrial Construction, LLC and Precision Plumbing and Service, LLC (which included approximately 1,079 employees).

For 2023, 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, we took the following steps:

● | We determined that, as of December 31, 2023, our employee population consisted of approximately 14,900 individuals, all of whom were located in the United States. This population consisted of all of our full-time, part-time, and seasonal employees. This population does not include independent contractors or leased workers who were engaged through an unaffiliated third-party staffing agency. We also excluded approximately 961 employees of Eldeco, Inc. and DECCO, Inc., which are companies that we acquired during 2023 in transactions that closed on February 1, 2023 and October 2, 2023, respectively.
● | To identify the median employee from our employee population, we used the amount of salary, wages, bonuses, commissions, and overtime pay of our employees as reflected in our payroll records as reported to the Internal Revenue Service on Form W-2 for 2024. Because only a small portion of Company employees receive grants of equity awards, when identifying the median employee we did not take into account any amounts reported on the employees’ Forms W-2 for 2024 with respect to stock option exercises or the vesting of equity awards. We also did not annualize the compensation of any individuals who were employed for less than the full calendar year.
● | We identified our median employee using this compensation measure, which was consistently applied to all our employees who were included in the calculation. Since all our employees are located in the United States, as is our Chief Executive Officer, we did not make any cost-of-living adjustments in identifying the median employee.

For 2024, we calculated this same employee’s compensation in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $59,611. The difference between such employee’s salary, wages, bonuses, commissions, and overtime pay reflected in such employee’s Form W-2 and the employee’s annual total compensation represents matching contributions by the Company to such employee’s account under the Company’s 401(k) Plan.

With respect to the annual total compensation of our Chief Executive Officer, we used the amount reported in the “Total” column of our 2024 Summary Compensation Table included in this proxy statement.

The Company recognizes that employees are a key asset and are vital to the Company’s continued success. In addition to the Company’s commitment to provide fair and equitable wages and benefits to employees, the Company also periodically conducts formal and informal surveys at all levels of the organization to gauge employee satisfaction and engagement.

The peer group used for this purpose is the S&P 400 Capital Goods Index. While not directly comparable, the Company believes that the S&P 400 Capital Good Index is an appropriate trade or line of business index.

(5) | The dollar amounts reported in column (h) represent the amount of net income reflected in the Company’s audited financial statements for the applicable year.

(6) | The amounts reported in column (i) represent the Company’s earnings per share, which the Company has determined represents the most important performance measure used to link compensation actually paid to our PEO and other NEOs to the Company’s performance.

Report of the Audit Committee

The Audit Committee of the Board of Directors of the Company oversees the Company’s financial reporting process on behalf of the Board of Directors. The committee is made up solely of independent directors, as defined in the applicable NYSE and SEC rules, and it operates under a written charter, amended and effective as of May 2021, reviewed as of March 2025, and approved by the Board of Directors, which is available under the “Governance” tab on the Company’s website at http://investors.comfortsystemsusa.com.

Management has the primary responsibility for the financial statements and the reporting process, including the Company’s internal controls. In fulfilling its oversight responsibilities, the Audit Committee has reviewed and discussed the audited financial statements in the Annual Report with management. The discussion explored the quality, not just the acceptability, of the accounting principles, the reasonableness of significant judgments, and the clarity of each of the key disclosures in the financial statements.

As part of its oversight of the Company’s financial statements, the Audit Committee reviewed and discussed with management and with the Company’s independent auditors, Deloitte & Touche LLP, the audited financial statements of the Company for the year ended December 31, 2024. The committee discussed with Deloitte & Touche LLP, who is responsible for expressing an opinion on the conformity of the audited financial statements with accounting principles generally accepted in the United States, such matters as are required to be discussed by Statement on Auditing Standards No. 16, as amended (Communications with Audit Committees), relating to the conduct of the audit. The Audit Committee also has discussed with Deloitte & Touche LLP the auditors’ independence from the Company and its management, including the matters in the written disclosures the committee received from the independent auditors, in compliance with applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant’s communications with the audit committee concerning independence, and the committee has considered the compatibility of non-audit services with the auditors’ independence.

The Audit Committee discussed with the Company’s internal and independent auditors the overall scope and plans for their respective audits. The committee meets regularly with the external auditors, with and without management present, to discuss the results of their examinations, their evaluations of the Company’s internal controls, and the content and quality of the Company’s financial reporting. Based on the review and discussions above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2024 and for filing with the SEC.

The preceding “Report of the Audit Committee” shall not be deemed soliciting material or to be filed with the Securities and Exchange Commission, nor shall any information in this report be incorporated by reference into any past or future filing under the Securities Act of 1933, as amended, or the Exchange Act, except to the extent the Company incorporates it by reference into such filing.

Other Information

Compensation and Human Capital Committee Interlocks and Insider Participation

Messrs. Anderson, Hardy, Mercado, and Sandbrook, and Ms. Skidmore, none of whom is or was an officer or employee of the Company or any of our subsidiaries through 2024, served on the Compensation and Human Capital Committee during 2024. None of the Company’s executive officers serve on the board of directors or Compensation and Human Capital Committee, or any other committee serving an equivalent function, of another company that employs any member of the Board.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires the Company’s directors, officers, and persons who own more than 10% of a registered class of the Company’s equity securities to file with the SEC initial reports of ownership and reports of changes in ownership with the SEC and the NYSE. Officers, directors, and greater-than-ten-percent stockholders are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

To the Company’s knowledge, based solely upon review of the copies of such reports furnished to the Company during the year ended December 31, 2024, all directors, officers, and beneficial holders of more than 10% of any class of equity securities of the Company complied with all filing requirements.

Householding of Stockholder Materials

Some banks, brokers, and other nominee record holders may be participating in the practice of “householding” proxy statements and annual reports. This means that only one copy of the Company’s proxy statement or Annual Report to Stockholders may have been sent to multiple stockholders in the same household unless the Company has received contrary instructions from one or more of the stockholders. The Company will promptly deliver a separate copy of either document to any stockholder upon written request to the Company at the following address: Comfort Systems USA, Inc., Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, Texas 77057 or upon oral request directed to the Company’s Office of the General Counsel at (713) 830-9600. Any stockholder who wants to receive separate copies of the annual report and proxy statement in the future, or who is currently receiving multiple copies and would like to receive only one copy for his or her household, should contact the stockholder’s bank, broker, or other intermediary, or contact the Company by writing to the above address or by oral request at the above telephone number.

Certain Relationships and Related Transactions

In March 2011, the Board adopted a written Related Person Transactions Policy that codifies the Company’s policies and procedures regarding the identification, review, consideration, and approval or ratification of “related person transactions.” For purposes of this policy only, a “related party transaction” is a transaction, arrangement, or relationship (or any series of similar transactions, arrangements, or relationships) in which the Company and any “related person” are, were, or will be participants in which the amount involved exceeds $120,000. Transactions involving compensation directly paid to a Named Executive Officer or director for services provided directly to the Company in their role as an employee or director shall not be considered related person transactions under the policy. A “related person” is any executive officer, director, or more than 5% stockholder of the Company, including any immediate family members of such persons, and any entity owned or controlled by such persons.

Under the Company’s Related Person Transactions Policy, where a transaction has been identified as a potential related person transaction, the Company’s management shall present such potential related person transaction to the Audit Committee for review, consideration, and approval or ratification. The presentation shall include all information reasonably necessary for the Committee to determine the benefits of the related-party transaction and whether the related-party transaction is commercially comparable to an otherwise unrelated transaction of similar nature and management’s recommendation related thereto.

Interest of Certain Persons in Matters to Be Acted Upon

The Audit Committee, in approving or rejecting the proposed related person transaction, considers all the relevant facts and circumstances deemed relevant by and available to the Audit Committee, including, but not limited to (i) the risks, costs, and benefits to the Company, (ii) the impact on a director’s independence in the event the related person is a director, immediate family member of a director, or an entity with which a director is affiliated, (iii) the terms of the transaction, (iv) the availability of other sources for comparable services or products, and (v) the terms available to or from, as the case may be, unrelated third parties or to or from employees generally. The Audit Committee approves only those related-party transactions that, in light of known circumstances, are in, or are not inconsistent with, the Company’s best interests and those of the Company’s stockholders, as the Audit Committee determines in the good faith exercise of its discretion. The Audit Committee approved the following related party transactions for fiscal year 2024: Gaurav Kapoor, a member of the Company’s Board of Directors, is the Chief Financial & Operations Officer of AECOM, an infrastructure consulting firm delivering professional services throughout a construction project lifecycle. The Company’s subsidiaries occasionally engage AECOM for services in the ordinary course of business. The total for all payments to AECOM by the Company or its subsidiaries was approximately $230,000 in 2024. Mr. Kapoor was not involved in the decision-making process for any of the transactions with the Company’s subsidiaries.

From time to time, the Company or its subsidiaries may have employees who are related to our executive officers or directors. The Company employed no such persons in 2024.

See the subsection above titled “Compensation and Human Capital Committee Interlocks and Insider Participation” for other information required to be disclosed here.
