Annual Meeting of Stockholders

May 22, 2018

PROXY STATEMENT

GENERAL MEETING INFORMATION

Why am I receiving this proxy statement?

The enclosed proxy is solicited by the Board of Directors (the “Board”) of Comfort Systems USA, Inc. (the “Company”) for the 2018 Annual Meeting of Stockholders (the “Annual Meeting”), to be voted at the Annual Meeting. This proxy statement and the enclosed proxy are first being provided to stockholders on or about April 13, 2018.

When and where is the 2018 Annual Meeting of Stockholders?

The Annual Meeting will be held at The Houstonian, 111 North Post Oak Lane, Houston, Texas 77024, at 11:00 a.m. local time on Tuesday, May 22, 2018, and at any reconvened meetings after any adjournments or postponements thereof.

Who can vote?

The holders of record of shares of the Company’s common stock, $.01 par value per share (the “Common Stock”), at the close of business on March 23, 2018 (the “Record Date”) are entitled to notice of and to vote at the Annual Meeting.

How do I vote?

If you are a record stockholder, you may vote in person at the Annual Meeting or by proxy. You may submit your vote by proxy by providing your voting instructions by internet or telephone or by signing, dating and returning a proxy card. The instructions for each method of voting are on the proxy card. If you wish to vote in person at the meeting, be sure to bring a form of personal picture identification with you.

If your stock is held by a broker, bank or other nominee (in “street name”) and you wish to vote in person at the meeting, in addition to picture identification, you should bring both (i) an account statement or a letter from the record holder indicating that you owned the shares as of the record date, and (ii) a proxy issued in your name, which you must obtain from the record holder.

What are the voting rights of holders of Common Stock?

Each share of Common Stock is entitled to one vote on each matter before the Annual Meeting.

What are my voting choices and what is the required vote?

By giving us your proxy, you authorize the persons named on the proxy card to vote your shares in the manner you indicate at the Annual Meeting or at any adjournments or postponements thereof.

Table of Contents

Proposal 1: Election of Directors

In the vote on the election of director nominees nominated by the board of directors to serve until the 2019 Annual Meeting, stockholders may:

(a)vote for all nominees;

(b)withhold authority from the proxy holders to vote for all nominees; or

(c)vote for all nominees except those specified.

The Board recommends a vote FOR all nominees. If a quorum is present, the nine 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 “Proposal Number 1: Election of Directors – 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.

Proposal 2: Ratification of Auditors

In the vote on whether to ratify the selection of Ernst & Young LLP as independent auditors for the Company for the year ending December 31, 2018, stockholders may:

(a)vote for ratification;

(b)vote against ratification; or

(c)abstain from voting on ratification.

The Board recommends a vote FOR ratification. If the stockholders do not ratify the selection, the Audit Committee will reconsider whether to retain Ernst & Young LLP, but still may retain them. Even if the selection is ratified, the Audit Committee, in its discretion, may change the appointment at any time during the year if it determines that such a change would be in the best interests of the Company and its stockholders. The affirmative vote of a majority of the votes cast by stockholders represented at the Annual Meeting and entitled to vote on this proposal will be required to ratify the appointment of the independent auditors. Abstentions will be counted toward a quorum, but will not be taken into account in determining the outcome of this vote.

Proposal 3: Non‑Binding Advisory “Say on Pay” Vote

In the non‑binding advisory vote on whether to approve the compensation paid by the Company to its named executive officers, stockholders may:

(a)vote for approval;

(b)vote against approval; or

(c)abstain from voting on the approval.

2

Table of Contents

The Board recommends a vote FOR approval. The affirmative vote of a majority of the votes cast by stockholders represented at the Annual Meeting and entitled to vote on this proposal will constitute the stockholders’ non‑binding approval with respect to the Company’s executive compensation programs. The Board and the Compensation Committee will review the voting results and take them into consideration when making future decisions regarding executive compensation. Abstentions and broker non‑votes will be counted toward a quorum, but will not be taken into account in determining the outcome of this vote.

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, 37,134,435 shares of Common Stock, representing the same number of votes, were outstanding. Therefore, the presence of holders of Common Stock representing at least 18,567,218 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, 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 Ernst & Young LLP as the Company’s auditors for 2018 in Proposal 2, and FOR approval with respect to the Company’s executive compensation programs 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.

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 21, 2018, 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.

Table of Contents

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, Corporate Compliance Policy, and Board committee charters?

All these documents can be found on our website at http://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, 2017, 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.

Table of Contents

Members of the Board are encouraged to attend the Annual Meeting and all members of the Board attended the Annual Meeting in 2017. Additional information regarding the determination of director independence is set forth below under “Corporate Governance—Independence.” Each director has attended at least 75% of the aggregate number of meetings of the Board and the Board committees of which he or she was or is a member that took place during his or her term of office.

The Board has several committees. Each of these committees and their members are described below. The Board has adopted a written charter for each of these committees which, together with the Board’s Governance Standards and Independence Guidelines, are available on the Company’s website at http://investors.comfortsystemsusa.com under the “Governance” tab, or by writing to Comfort Systems USA, Inc., Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, Texas 77057.

Audit Committee

The Audit Committee, which held eight regular meetings during 2017, reviews with management and the independent auditors the Company’s quarterly and annual financial statements, the scope of the audit, any comments made by the independent auditors and such other matters as the committee deems appropriate. In addition, the Audit Committee reviews the performance and retention of the Company’s independent auditors and reviews with management those matters relating to compliance with corporate policies, as the committee deems appropriate. The Audit Committee reviews and reassesses the adequacy of its charter every year and has done so for 2018.

The current members of the Audit Committee are Ms. Skidmore and Messrs. Krusi, Schultz and Tang, none of whom is or has been an executive officer or employee of the Company at any time. The Board has determined that the committee consists entirely of directors who meet the independence requirements of the NYSE’s listing standards, the Board’s Independence Guidelines (discussed below at “Corporate Governance—Independence”) and the rules and regulations under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In addition, the Board has determined that each member of the Audit Committee is financially literate, and based on accounting or related financial management expertise, that each of Ms. Skidmore and Messrs. Krusi, Schultz and Tang are audit committee financial experts.

Compensation Committee

The Compensation Committee, which held five regular meetings and one special meeting during 2017, establishes and administers the Company’s executive compensation program and reviews and advises the Board with respect to major organizational changes, leadership development and leadership succession, other than the succession of the Chief Executive Officer, which is overseen by the Governance and Nominating Committee. The Compensation Committee establishes and regularly reviews the compensation levels of executive officers and other key managers, and also reviews incentive awards. The members of the committee are Messrs. Anderson, Bulls, Krusi, Myers, and Tang, none of whom is or has been an executive officer or employee of the Company at any time. The committee may delegate any of its responsibilities to a subcommittee thereof. The committee has the authority to hire a professional consultant to review and analyze the Company’s compensation programs. In 2017, the committee retained Pearl Meyer & Partners to advise the committee during its review of the Company’s short-term incentive compensation program and to provide a comprehensive analysis of executive compensation survey data and market trends for each named executive officer of the Company. The committee’s work with Pearl Meyer & Partners is described in greater detail below in the subsection titled “Independent Compensation Consultant.” Further, as discussed below in the section titled “Compensation Discussion and Analysis,” the Compensation Committee consults with management in developing compensation plans for the Company. The Board has determined that the Compensation Committee consists entirely of directors who meet the independence requirements of the NYSE listing standards, the Board’s Independence Guidelines, and the rules and regulations under the Exchange Act.

Governance and Nominating Committee

The Governance and Nominating Committee, which held two regular meetings and three special meetings during 2017, evaluates the structure and membership of the Board, evaluates candidates for nomination to the Board as

appropriate with an emphasis on diversity of viewpoint and professional experience, reviews the compensation structure for the non-employee directors and the frequency and content of meetings, establishes and reviews the Company’s succession plan for its Chief Executive Officer, and makes recommendations to the Board on all such matters. The committee’s diversity policy values diversity in its broadest sense, reflecting, but not limited to, an individual’s profession, geography, gender, ethnicity, race, skills, background and experience, and endeavors to include candidates who are diverse, including in terms of race and gender, in the qualified pool from which Board candidates are chosen. The committee periodically examines the composition of the Board to ensure that the Board, taken as a whole, has the necessary skills and experience to steer the Company toward its stated objectives, as well as the necessary skills and experience to set the Company’s future strategies. Directors are nominated or elected by the Board, and stockholders may nominate directors as described further in “Corporate Governance—Director Nomination by Stockholders.” The committee identifies Board candidates through a variety of formal and informal channels. The committee has the authority to hire a professional search firm to help identify candidates with specific qualifications; although it has no current engagement with any such firm, the committee worked with a third party search firm in 2017 and early 2018 to identify a potential new director. The third party search firm retained by the committee recommended William J. Sandbrook as a new director based on criteria established by the Committee. The current members of the committee are Messrs. Tang, Anderson, Bulls, and Schultz and Ms. Skidmore, each of whom the Board has determined to meet the independence requirements of the NYSE listing standards, the Board’s Independence Guidelines, and the rules and regulations under the Exchange Act.

Corporate Governance

The Board believes the purpose of corporate governance is to maximize stockholder value in a manner consistent with legal requirements and the highest standards of integrity. The Board has adopted and adheres to corporate governance practices that the Board believes promote this purpose, are sound practices, and represent best practices. The Board continually reviews these governance practices, Delaware law (the state in which the Company is incorporated), the rules and listing standards of the NYSE and SEC regulations, and best practices suggested by recognized governance authorities. The corporate Governance Standards are posted on the Company’s website at http://investors.comfortsystemsusa.com under the “Governance” tab and are also available upon request to Comfort Systems USA, Inc., Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, Texas 77057.

Code of Ethics

The Company adopted the Compliance Policy in 1997, the year the Company was founded. That policy, with subsequent amendments discussed, approved and adopted by the Board, remains in effect and applies to the Company’s directors, officers and employees who are subject to disciplinary action, including termination, for violations of the policy. The policy forms the basis of the Company’s ethics and compliance program and covers a wide range of areas. Many Company policies are summarized in the Compliance Policy including conflict of interest, insider trading, confidentiality, and compliance with all laws and regulations applicable to the conduct of the Company’s business. The Compliance Policy is regularly reinforced to the Company’s employees and management through periodic ethics, equal opportunity employment and anti-corruption trainings. Any amendments to the Compliance Policy or the grant of a waiver from a provision of the policy requiring disclosure under applicable SEC rules will be disclosed to the public. The Compliance Policy is posted under the “Governance” tab of the Company’s website at http://investors.comfortsystemsusa.com and is also available upon request to Comfort Systems USA, Inc., Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, Texas 77057.

Independence

The Board has adopted Independence Guidelines to assist the Board in making independence determinations relating to members of the Board. The criteria are consistent with the NYSE listing standards regarding director independence. For a director to be considered independent, the Board must determine that the director does not have a material relationship, directly or indirectly, with the Company. The Independence Guidelines are published on our website, http://investors.comfortsystemsusa.com under the “Governance” tab, and are also available by written request to Comfort Systems USA, Inc., Office of the General Counsel, 675 Bering Drive, Suite 400, Houston, TX 77057.

Table of Contents

The Board has considered the independence of its members in light of the Independence Guidelines and the rules and regulations under the Exchange Act and NYSE, including each director’s affiliations and relationships, and has determined that Ms. Skidmore and Messrs. Anderson, Bulls, Krusi, Myers, Sandbrook, Schultz and Tang, who together constitute a majority of the Board, qualify as independent directors of the Company.

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.” Stockholders desiring to recommend a candidate must submit the recommendation to the Governance and Nominating 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, (b) a non‑employee director under Rule 16b‑3 of the Exchange Act, and (c) to the extent applicable, an outside director under Section 162(m) of the Internal Revenue Code of 1986, as amended from time to time, and pertinent regulations promulgated thereunder by the Internal Revenue Service (collectively, the “Code”);

| · |  | Consent to serve on the Board, if nominated and elected; and

| · |  | Agree to complete, upon request, a customary director’s questionnaire.

The Governance and Nominating Committee will evaluate any candidate recommended by a stockholder to determine whether he or she is highly qualified. The committee evaluates candidates recommended by stockholders in the same way it evaluates candidates proposed from other sources. 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.

Retirement Policy

Under the Company’s corporate Governance Standards, a director shall not be a candidate for reelection after his or her seventy-second birthday.

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 Chairman 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 Chairman 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 Chairman 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 Chairman 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 interest of the Company and its stockholders for the roles of Chairman 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 Chairman 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 Committee and the Governance and Nominating 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. 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 and the Company’s risk appetite. These activities are aligned with the Company’s strategy. Additionally, the Audit Committee, Compensation Committee, and Governance and Nominating Committee consider risks that fall within their respective areas of responsibilities. 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 each of the quarterly meetings held in 2017. 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, and strategic risks. The Risk Committee presents comprehensive reports directly to the Board at least annually.

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 Chairman of the Board following certification of the stockholder vote. The Governance and Nominating 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

12

Table of Contents

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 Governance and Nominating 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, TX 77057.

Director Compensation for 2017

In 2017, each director who was not an employee of the Company or one of its subsidiaries received, in equal quarterly installments, an annual cash fee based on service as follows: $60,000 for service on the Board; $30,000 to serve as the chair of the Audit Committee; $20,000 to serve as the chair of the Compensation Committee or the Governance and Nominating Committee; and $50,000 to serve as the chairman of the Board, in each case, prorated for partial years of service.

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 $140,000. Pursuant to the Company’s 2017 Omnibus Incentive Plan, the maximum grant date fair value of awards granted to each individual non-employee director in any calendar year may not exceed $400,000. The Board has adopted stock ownership guidelines that require each non-employee director to own an amount of shares of Common Stock 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 Governance and Nominating Committee evaluates each director’s stock ownership on an annual basis. At the time of such evaluation, the value of the stock ownership 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 guidelines. The Governance and Nominating Committee may modify these stock ownership guidelines in its reasonable discretion and is

13

Table of Contents

authorized to make exceptions to these stock ownership guidelines when special circumstances arise. All non-employee directors currently comply with these ownership guidelines.

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, paid or awarded, as the case may be, to each of the Company’s non‑employee directors during 2017.

Name(1) |  | Director Fees Earned or Paid in Cash ($) |  | Stock Awards ($)(2) |  | All Other Compensation ($)(3) |  | Total ($) |

James H. Schultz |  | $ | 67,912 | (4) | $ | 139,977 |  | $ | 0 |  | $ | 207,889 |
Constance E. Skidmore |  | $ | 90,000 |  | $ | 139,977 |  | $ | 0 |  | $ | 229,977 |
Vance W. Tang |  | $ | 72,088 | (4) | $ | 139,977 |  | $ | 0 |  | $ | 212,065 |

| (1) |  | Messrs. Lane and Giardinelli also served as members of the Board during 2017, but were employees of the Company or one of its subsidiaries in 2017, and received no additional compensation for their service on the Board. Mr. Lane’s compensation is included in the “Summary Compensation Table” included elsewhere in this proxy statement.

| (2) |  | Represents grants of 4,018 fully-vested shares of Common Stock. The aggregate grant date fair value of the shares was computed in accordance with FASB ASC Topic 718 and is based on the number of shares granted multiplied by the fair market value of the Common Stock on the date of grant.

| (3) |  | 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.

| (4) |  | Mr. Schultz served as the chair of the Governance and Nominating Committee from January 1, 2017 to May 23, 2017, and Mr. Tang served as the chair of the Governance and Nominating Committee from May 23, 2017 to December 31, 2017. Consequently, Mr. Schultz and Mr. Tang received a pro rata payment for each director’s period of service as chair of the Governance and Nominating Committee in 2017.

In March 2018, upon the recommendation of the Governance and Nominating Committee, which was based on an analysis of several factors, including survey data from the National Association of Corporate Directors and the Board’s historical non-employee director compensation practices, the Board approved the following increases to non-employee director compensation. These changes will take effect following the Annual Meeting:

| · |  | The annual fee for service as the chairman of the Board will increase from $50,000 to $60,000.

| · |  | Each non-employee director who continues in office or is elected at an annual stockholder meeting will receive an award of fully-vested shares of Common Stock having a fair market value on the grant date equal to $160,000.

| · |  | All other fees for service on the Board will remain unchanged.

PROPOSAL NUMBER 2

RATIFICATION OF THE SELECTION OF INDEPENDENT AUDITORS

The Audit Committee has re‑appointed Ernst & Young LLP as the Company’s independent auditors for the year ending December 31, 2018. Ernst & Young LLP was the Company’s independent auditor for the year ended December 31, 2017.

We expect that representatives of Ernst & Young 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 Ernst & Young LLP as the Company’s independent auditors for 2018. If the stockholders fail to ratify the appointment, the Audit Committee will reconsider its selection, but it still may decide to retain Ernst & Young 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 Ernst & Young LLP as independent auditors for the Company for the year ending December 31, 2018. Ernst & Young LLP acted as independent auditors for the Company for the year ended December 31, 2017. Fees to the Company and its subsidiaries for professional services rendered by Ernst & Young LLP during 2017 and 2016 were as follows:

Description |  | 2017 |  | 2016 |
Audit Fees |  | $ | 2,149,640 |  | $ | 1,921,287 |
Audit‑Related Fees |  | $ | 0 |  | $ | 0 |
Tax Fees |  | $ | 0 |  | $ | 0 |
All Other Fees |  | $ | 0 |  | $ | 0 |

The amount of audit fees for 2017 is based on a fees estimate determined with input from Ernst & Young LLP for audit services provided to us by Ernst & Young in connection with the audit of our 2017 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 sufficient detailed information so that it can make well‑reasoned assessments of the impact of the services on the independence of the auditors. In 2017, all of 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 NUMBER 3

ADVISORY VOTE TO APPROVE THE COMPENSATION OF THE 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 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 named executive officers (the “Named Executive Officers”) based on Company performance. In particular, the Compensation Committee strives to attract, retain and motivate exceptional executive officers, to reward past performance as measured against 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 Committee uses a combination of short- and long-term incentive compensation to reward near-term performance and to encourage executive officers’ commitment to our long-range strategic business goals. It is the intention of the Compensation 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 Committee retains compensation consultants and reviews survey and peer group data, provided by Equilar, to ensure that compensation for key positions is properly aligned with market practices. Further, the Company’s commitment to aligning pay with performance is evidenced by the compensation paid to or earned by the Named Executive Officers.

As described in the CD&A, we believe our compensation program is effective, appropriate, and strongly aligned with the long‑term interests of our stockholders and that the total compensation packages provided to the Named Executive Officers (including potential payouts upon a termination of employment or change in control) are 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 the more detailed information about our compensation philosophy and objectives and the past compensation of 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 has 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 give our stockholders an opportunity to 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 Committee, will not overrule any decisions made by the Board or the Compensation Committee, and will not require the Board or the Compensation Committee to take any action. Although the vote is non-binding, the Board and the Compensation Committee value the opinions of our stockholders, and will carefully consider the outcome of the vote when making future compensation decisions for the Named Executive Officers. In particular, if there is 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 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 2019.

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

“RESOLVED, that the compensation paid 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.”

RATIO OF CHIEF EXECUTIVE OFFICER COMPENSATION TO MEDIAN COMPANY EMPLOYEE COMPENSATION

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act, and Item 402(u) of Regulation S-K, 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.

18

Table of Contents

For 2017, 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 $50,164; and

| · |  | The annual total compensation of our Chief Executive Officer, as reported in the Summary Compensation Table included elsewhere in this proxy statement, was $2,463,023.

Based on this information, for 2017, 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 49.1 to 1. |

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, 2017, our employee population consisted of approximately 7,816 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 739 employees of BCH Holdings, Inc. and each of its wholly-owned subsidiaries, Century Mechanical Solutions, Inc. and KTU of Spokane, Inc., which are companies that we acquired during 2017 in transactions that closed on April 1, 2017 and July 1, 2017.

| · |  | 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 2017. 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 2017 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 of our employees who were included in the calculation. Since all of 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.”

| · |  | Once we identified our median employee, we combined all of the elements of such employee’s compensation for 2017 in accordance with the requirements of Item 402(c)(2)(x) of Regulation S-K, resulting in annual total compensation of $50,164. 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 2017 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.

COMPENSATION DISCUSSION AND ANALYSIS

Overview

This Compensation Discussion and Analysis (the “CD&A”) provides an overview and analysis of the Company’s executive compensation program and policies, the material compensation decisions made with respect to 2017 compensation, and the material factors considered in making those decisions. The CD&A focuses on the compensation paid to the Named Executive Officers unless noted otherwise. For 2017, the Named Executive Officers are:

Brian E. Lane, President and Chief Executive Officer

William George, Executive Vice President and Chief Financial Officer

Trent T. McKenna, Senior Vice President, General Counsel and Secretary

Julie S. Shaeff, Senior Vice President and Chief Accounting Officer

James Mylett, Former Senior Vice President—Service*

*Mr. Mylett provided notice to the Company on January 9, 2017 of his decision to resign from the Company and terminated employment effective on February 1, 2017. For more information regarding the compensation that Mr. Mylett received in connection with his termination of employment, see “Potential Payments on Termination or Change in Control” below.

The Board has delegated to the Compensation Committee (referred to in this CD&A simply as the “Committee”) the duty of designing and overseeing the Company’s executive compensation program. The Committee is comprised entirely of independent (pursuant to NYSE, SEC and Internal Revenue Service rules, and the Company’s own Independence Guidelines) members of the Board. The Company’s executive compensation program is designed to:

| · |  | attract, motivate, and retain talented executive officers so that the Company can achieve its best results and maximize long‑term stockholder return;

| · |  | align the long‑term interests of Company executive officers with the interests of stockholders; and

| · |  | pay compensation that is directly tied to the performance of the Company and the Common Stock.

2017 Performance Highlights

To put the Company’s 2017 compensation decisions in context, the following summarizes the Company’s key financial and business results for 2017, a year in which the Company continued to experience strong performance:

| · |  | Revenue increased to $1.79 billion in 2017 as compared to $1.63 billion in 2016.

| · |  | Gross profit increased by $22.3 million to $366.3 million in 2017 as compared to $344.0 million in 2016.

| · |  | Free cash flow (“FCF”) increased to $80.0 million in 2017 as compared to $69.0 million in 2016.

| · |  | Backlog as of December 31, 2017 was $948.4 million as compared to $763.4 million as of December 31, 2016.

| · |  | For purposes of our 2017 annual incentive plan and dollar-denominated performance-vesting restricted stock unit (“PSU”) performance, our non‑GAAP earnings per share (“EPS”) was $1.74, as further described below, as compared to $1.72 in 2016.

20

Table of Contents

As a result of this performance, the currently employed Named Executive Officers each received 91.2% of their respective EPS target award and 136.6% of their respective FCF target award under the corporate financial incentive portion of the Company’s 2017 annual incentive plan, as further described below. For a description of how EPS and FCF are determined under this plan, please see “Annual Incentive Plan” below. We use the terms EPS and FCF in this CD&A to refer to those metrics as determined under our annual incentive plan.

Compensation and Governance Practices

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

| · |  | A majority of each Named Executive Officer’s compensation is at-risk (i.e., variable and not fixed).*

| · |  | A majority of each Named Executive Officer’s compensation is tied to the Company’s financial performance and growth in stockholder value.*

| · |  | Forty percent of each Named Executive Officer’s equity awards are subject to the Company achieving specific performance criteria over a three‑year time horizon.*

| · |  | Executive officers and directors are subject to stock ownership guidelines.

| · |  | The Company has adopted a compensation clawback policy and an anti‑hedging/pledging policy that applies to all executive officers.

| · |  | The Committee engages an independent compensation consultant to advise on executive compensation.

*Assuming target performance is achieved, when applicable, and based on grant date values of equity-based awards.

Consideration of Stockholder Advisory Vote

In designing the overall executive compensation program, the Committee also values and considers stockholder input. While evaluating the Company’s 2017 executive compensation program, the Committee considered the stockholder advisory vote on the compensation paid to the Named Executive Officers that was taken in 2017. The Committee viewed the outcome of that advisory vote—approval by more than 94% of the shares voted—as indicating that the Company’s stockholders generally support the Company’s overall approach to executive compensation and made no changes to our executive compensation program as a result of the vote.

Compensation Philosophy and Objectives

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

| · |  | providing competitive base pay consistent with job scope, experience and related skills;

| · |  | linking bonus opportunities to the Company’s performance;

| · |  | granting equity compensation at competitive levels, a significant portion of which is performance‑based;

| · |  | avoiding unnecessary and imprudent risks; and

21

Table of Contents

| · |  | attracting and motivating talented executive officers and minimizing turnover of senior‑level Company employees, which contributes to the stability and continuity of senior leadership.

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

| · |  | pay competitive levels of salary and total compensation;

| · |  | link executive pay to Company performance by making a significant portion of pay variable and not fixed;

| · |  | align the interests of management with the long‑term interests of stockholders; and

| · |  | reward long‑term results.

To achieve these objectives, the Committee implements a “pay‑for‑performance” philosophy using the guiding principles that: (i) compensation should be incentive‑driven, with a balanced short‑term and long‑term focus; (ii) a significant portion of pay for executive officers should be “at-risk”; (iii) a significant portion of annual incentive compensation should be tied to the overall performance of the Company; and (iv) a portion of annual incentive compensation should be tied to individual performance criteria.

Role of the Chief Executive Officer

Management, led by the Chief Executive Officer, at least annually makes recommendations to the Committee regarding the establishment and modification of compensation packages for the Company’s senior management (except that no member of management makes a recommendation with respect to his or her own compensation package). The Committee considers management’s recommendations during its regularly-scheduled meetings, and may choose to adopt the recommendations or not adopt or modify them 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 2017, the Committee retained Pearl Meyer & Partners (“Pearl Meyer”) to advise the Committee on the design and administration of the Company’s annual incentive plan and to provide a comprehensive analysis of executive compensation survey data and market trends. The Committee regularly reviews the services provided by its outside consultants and believes that Pearl Meyer is independent in providing executive compensation consulting services. In making this determination, the Committee noted that during 2017:

| · |  | Pearl Meyer 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 executive and director compensation consulting. Specifically, Pearl Meyer does not provide, directly or indirectly through affiliates, any non‑executive compensation services, such as pension consulting or human resource outsourcing;

| · |  | Pearl Meyer maintains a conflicts policy, which was provided to the Committee with specific policies and procedures designed to ensure independence;

| · |  | Fees paid to Pearl Meyer by the Company during 2017 were less than 1% of Pearl Meyer’s total revenue;

| · |  | None of the Pearl Meyer consultants working on Company matters had any business or personal relationship with Committee members;

22

Table of Contents

| · |  | None of the Pearl Meyer consultants working on Company matters had any business or personal relationship with any executive officer of the Company; and

| · |  | None of the Pearl Meyer consultants working on Company matters own Company stock.

The Committee monitors the independence of its compensation consultant on a periodic basis.

During 2017 the Committee consulted with Pearl Meyer regarding the Company’s annual incentive plan design and administration, which included a comprehensive analysis regarding market trends and executive compensation survey data provided by Equilar, as described below. Following the Committee’s initial engagement of Pearl Meyer in 2013 to provide the Committee with detailed analysis and recommendations on the structure of the Company’s annual incentive plan in terms of design, metrics, and payout opportunities, the Committee has continued to periodically refine the annual incentive plan based on a number of factors, including Pearl Meyer’s recommendations, market trends in the Company’s industry and general economic conditions.

Peer Group and the Benchmarking Process

Since 2010, the Committee has also reviewed executive compensation levels annually based on competitive compensation data provided by Equilar, an information services firm with products focusing on analyzing and benchmarking executive and director compensation information. The Committee does not attempt to set executive compensation at a pre-defined percentile of the market, but the Committee does use the comparative data in an effort to be better informed in its 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 for the Named Executive Officers and, for this reason, does not depend solely on a “peer group” to determine Named Executive Officer compensation. It does, however, review executive compensation against compensation paid to executive officers holding similar positions in the companies contained in the peer group established for the Company by Institutional Shareholder Services (ISS), which includes the companies listed in the table below.

| ISS Peer Group |
| Actuant Corporation |
| Cubic Corporation |
| GATX Corporation |
| Chart Industries, Inc. |
| Esterline Technologies Corporation |
| Valmont Industries, Inc. |
| Aegion Corporation |
| Granite Construction Incorporated |
| Barnes Group Inc. |
| Dycom Industries, Inc. |
| Great Lakes Dredge & Dock Corporation |
| MYR Group Inc. |
| Primoris Services Corporation |
| Wabash National Corporation |

The Committee uses Equilar data from companies included in the ISS peer group to provide a general market review of the reasonableness of Chief Executive Officer and Chief Financial Officer total compensation levels, and the Committee uses a combination of the ISS peer group and Equilar survey data from certain other industry companies to provide a general market review of the reasonableness of total compensation levels for the General Counsel and Chief Accounting Officer; however, the Committee does not use the ISS peer group for any other purpose or otherwise formally benchmark the compensation of the Named Executive Officers.

Table of Contents

Use of Tally Sheets

The Committee routinely uses tally sheets to assist it in analyzing the Named Executive Officers’ total compensation. Tally sheets provide the Committee with information about the following components of compensation paid 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 separation from service, death or 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 exercise values of outstanding option grants and current values of RSU and 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, position tenure and succession planning, 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 target the Chief Executive Officer’s compensation at any specific percentile of compensation at similarly-situated or peer group companies, the Committee does use the data provided by Equilar as context in reviewing the Chief Executive Officer’s overall compensation levels and approving recommended compensation actions. Based on compensation data provided by Equilar, the Chief Executive Officer’s compensation is below the market median when compared to other companies in the Company’s peer group established by ISS (described above).

Table of Contents

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 |  |  Levels are evaluated annually by the Committee
|  |  Attract and retain strong executive talent |  |  In 2017, base salaries were established based on a number of factors, including advice from Pearl Meyer and analysis of market trends and economic conditions
|  |  |  | 
Annual Incentive Plan |  |  Reward annual financial, operational, and individual performance |  |  Award targets are established as a percentage of base salary
|  |  |  |  Majority of each award is based on objective, pre‑established criteria related to the Company’s EPS performance against target
|  |  |  | 
Long‑term Incentive Awards |  |  Reward long‑term Company performance |  |  Awards are provided through a mix of stock options, time‑vesting restricted stock units (“RSUs”), and dollar‑denominated PSUs
|  |  Encourage focus on growing stockholder value |  |  Stock options only have value if the price of the Company’s Common Stock increases
|  |  Align management’s interests with stockholders’ interests |  |  Dollar‑denominated PSUs are earned based on objective, pre‑established performance measures, including total shareholder return relative to certain comparable companies and EPS performance against target
|  |  Encourage retention of key management employees, stability, and continuity of leadership |  |  Stock options and 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 |  |  Participation in health, welfare, and retirement benefit plans on the same terms as all employees at the Company’s corporate office
|  |  Provide basic financial stability |  |

25

Table of Contents

While base salaries, together with health, welfare and retirement benefits, are designed to provide basic compensation and financial stability to the executive officers, the purpose of annual incentive compensation is primarily to encourage the 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 stock options, RSUs and PSUs, are designed to align executive officers’ interests with those of stockholders, incentivize executive officers to attain longer-term goals and also to 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” for the Named Executive Officers. In setting executive officer compensation, the Committee considers the aggregate compensation payable to the executive, assuming target performance is achieved, and the forms of the compensation. The Committee seeks to achieve the appropriate balance between current cash compensation and incentives for the achievement of both annual and long-term financial and non-financial objectives.

Allocation Among Compensation Elements

For 2017, the portion of the Chief Executive Officer’s total direct compensation (assuming target performance was achieved and, for equity awards, based on grant date values at target) that was at-risk is illustrated as follows:

For 2017, the portion of Messrs. George’s and McKenna’s and Ms. Shaeff’s total direct compensation (assuming target performance was achieved and, for equity awards, based on grant date values at target) that was at risk is illustrated as follows, based on an average of their respective compensation:

26

Table of Contents

Although 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 “Fixed Pay” in the charts above.

Base Salary

The Committee determines base salary after considering several factors, including: the executive’s individual experience, previous job performance and individual skills. Only after weighing these factors does the Committee consider comparable indicators. The Committee uses management’s performance assessments, Company performance, survey data provided by Equilar, ISS peer group data (with respect to the Chief Executive Officer and Chief Financial Officer), and its own analysis of job performance to set each executive’s base salary at least annually. Based on the factors described above, on December 14, 2016, the Committee approved an increase in each Named Executive Officer’s base salary as set forth in the table below.

Named Executive Officer(1) |  | 2016 Base Salary |  | 2017 Base Salary |
Brian E. Lane |  | $ | 625,000 |  | $ | 670,000 |
William George |  | $ | 400,000 |  | $ | 426,000 |
Trent T. McKenna |  | $ | 340,000 |  | $ | 351,000 |
Julie S. Shaeff |  | $ | 270,000 |  | $ | 278,100 |

| (1) |  | The Committee also approved an increase to Mr. Mylett’s base salary from $350,000 in 2016 to $360,500 in 2017. However, Mr. Mylett resigned from the Company effective on February 1, 2017. For more information regarding Mr. Mylett’s resignation, see “Potential Payments on Termination or Change in Control” below.

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 objectives. For 2017, each of the Named Executive Officers was eligible to participate in the annual incentive plans on the terms described below except Mr. Mylett. References to “named executive officers” below do not include references to Mr. Mylett since he forfeited his right to receive any annual incentive for 2017 upon his resignation in February 2017.

The annual incentive plan consists of two distinct components: a corporate financial performance component and an individual performance component. In 2017, the principal component of the annual incentive plan rewarded the achievement of earnings-per-share (“EPS”) and free cash flow (“FCF”) goals (collectively, the “Corporate Financial Incentive”). 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 Committee believes that EPS remains an important metric for the Company because it encourages a focus on profitability. The second, smaller, component of the annual incentive plan rewarded the achievement of certain individual performance metrics (the “Individual Performance Incentive”). Target annual incentive opportunities for 2017 are summarized in the table below:

|  | Target Annual Incentive Opportunity as a Percent of Base Salary |
Named Executive Officer(1) |  | Target Corporate Financial Incentive |  | Target Individual Performance Incentive |  | Total Target Incentive Opportunity |
Mr. Lane |  | 100 | % | 10 | % | 110 | %
Mr. George |  | 90 | % | 10 | % | 100 | %
Mr. McKenna |  | 65 | % | 10 | % | 75 | %
Ms. Shaeff |  | 55 | % | 10 | % | 65 | %

27

Table of Contents

Corporate Financial Incentive Criteria

At the beginning of each year, the Committee sets a threshold, target and maximum performance level for each of EPS and FCF for purposes of the Corporation Financial Incentive component of the annual incentive plan. For each of the Named Executive Officers, the EPS portion of the Corporate Financial Incentive represents 70% of the total Corporate Financial Incentive, and the FCF portion of the Corporate Financial Incentive represents 30% of the total Corporate Financial Incentive. If both the EPS and FCF thresholds are not met, no portion of the Corporate Financial Incentive is paid. If only one of the EPS or FCF thresholds is met, then only that portion of the Corporate Financial Incentive is paid. The threshold, target and maximum performance levels for each of the corporate goals for 2017 bonuses were:

2017 Corporate Financial Incentive Criteria

EPS |  | FCF
Threshold |  | Target |  | Max |  | Threshold |  | Target |  | Max
$ | 1.04 |  | $ | 1.80 |  | $ | 2.36 |  | $ | 35.5M |  | $ | 64.4M |  | $ | 85.7M

The Committee establishes short-term incentive levels among the Named Executive Officers by assigning certain base salary percentages to each EPS and FCF performance level. Once set, the Committee has never previously adjusted the assigned base salary percentages, the EPS levels, or the FCF levels during the year; however, the Committee annually reserves the right to adjust these percentages or levels if it believes that an adjustment is appropriate and, for 2017, made an adjustment to the EPS calculation as described below. For the purpose of determining 2017 incentive compensation, (i) EPS is calculated from the Company’s audited financial statements for the year ended December 31, 2017 in accordance with GAAP, except that it does 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; and (E) any other unusual or non-recurring items as determined by the Committee; and (ii) FCF is calculated by excluding certain items related to acquisitions or sales of businesses less customary capital expenditures plus the proceeds from asset sales. For the year ended December 31, 2017, the Committee determined that it was appropriate to exclude a one-time charge taken in the fourth quarter of 2017 from the EPS calculation used for incentive compensation. This charge relates to a reduction in the carrying value of our deferred tax assets by $9.5 million, or $.25 per share, as a result of the reduction in the corporate income tax rate from 35% to 21% in the Tax Cuts and Jobs Act of 2017, which was signed into law on December 22, 2017. In December 2017, the Committee also determined that it would exclude the impact of tax reform legislation from the EPS calculation for purposes of the Corporate Financial Incentive for each Named Executive Officer for the year ending December 31, 2018. For a discussion of how we calculate FCF, see the “Liquidity and Capital Resources” section of our Annual Report on Form 10-K for the year ended December 31, 2017.

For 2017, the base salary percentages for each portion of the Corporate Financial Incentive are 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.

2017 Corporate Financial Incentive Levels

|  |  |  | EPS Incentive Award Levels (as a % of Base Salary) |  | FCF Incentive Award Levels (as a % of Base Salary) |
Named Executive Officer |  | Base Salary |  | Threshold |  | Target |  | Maximum |  | Threshold |  | Target |  | Maximum |
Mr. Lane |  | $ | 670,000 |  | 14 | % | 70 | % | 105 | % | 6 | % | 30 | % | 45 | %
Mr. George |  | $ | 426,000 |  | 12.6 | % | 63 | % | 94.5 | % | 5.4 | % | 27 | % | 40.5 | %
Mr. McKenna |  | $ | 351,000 |  | 9.1 | % | 45.5 | % | 68.25 | % | 3.9 | % | 19.5 | % | 29.25 | %
Ms. Shaeff |  | $ | 278,100 |  | 7.7 | % | 38.5 | % | 57.75 | % | 3.3 | % | 16.5 | % | 24.75 | %

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 other competing companies’ 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 met. The Committee believes that the added value that results from the Company’s

28

Table of Contents

achievement of EPS and/or FCF 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. To determine the assigned base salary percentages for each Named Executive Officer, in addition to historical and projected Company financial performance, the Committee considers the degree to which a Named Executive Officer’s efforts and job function are 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 uses data provided by Equilar and, with respect to the Chief Executive Officer and Chief Financial Officer, ISS peer group data, to assess the reasonableness of such assigned levels. The Committee did not adjust the base salary percentages for any Named Executive Officer in 2017.

The Company’s EPS and FCF for calculating incentive compensation achievement levels for 2017 was $1.74 and $80.0 million, respectively. The amounts earned by each of the Named Executive Officers in respect of the Corporate Financial Incentives under the annual incentive plan in 2017 are summarized in the table below.

Individual Performance Incentive

In addition to and independent of the Corporate Financial Incentive portion of the annual incentive plan, each Named Executive Officer is eligible to receive annual incentive compensation based on certain individual strategic objectives that relate to the executive’s achievement of established quantitative strategic goals (the Individual Performance Incentive).

At the beginning of each year, each Named Executive Officer, including the Chief Executive Officer, identifies individual performance goals and objectives for the upcoming year. Each Named Executive Officer’s individual performance goals are discussed and identified in consultation with the Chief Executive Officer, in the case of Messrs. George and McKenna, with the Chief Financial Officer, in the case of Ms. Shaeff, and with the Compensation Committee, in the case of Mr. Lane. These goals and objectives vary depending on the roles and responsibilities for each Named Executive Officer. For 2017, specific goals for each Named Executive Officer included:

Executive |  | 2017 Individual Performance Goals
Brian E. Lane |  |  | Grow acquired revenue
|  |  | Strategic personnel initiatives
|  |  | Improve Company‑wide employee safety measure(1)
William George |  |  | Grow acquired revenue
|  |  | Improve Company‑wide employee safety measure(1)
Trent McKenna |  |  | Litigation management and compliance strategic initiatives
|  |  | Benefits program strategic initiatives
|  |  | Improve Company‑wide employee safety measure(1)
Julie Shaeff |  |  | Complete implementation phase of new revenue recognition standard
|  |  | Achieve 2017 target implementations for ERP strategy
|  |  | Improve Company‑wide employee safety measure(1)

| (1) |  | The Company-wide employee safety measure tracks the OSHA Lost Time Incident Rate (“LTIR”), which is a nationally-recognized metric that tracks all injuries serious enough to require OSHA documentation of lost time. In addition to the LTIR performance metric, the Named Executive Officers are required to attend safety training classes on an annual basis. No safety incentive is payable to the Named Executive Officers if there is a work-related fatality of a Company employee during the year. In 2017, the Company did not have a work-related fatality, and the Company’s LTIR was improved from the prior fiscal year.

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

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

In executive session, the Committee reviews and discusses its evaluation of Mr. Lane’s performance over the past year and the performance summaries for each other Named Executive Officer. The Committee also considers significant individual contributions beyond established goals and each executive’s overall effectiveness. In the Committee’s sole discretion, based on its evaluation of these factors, the Committee then grades each executive’s attainment of individual performance goals to determine the Named Executive Officer’s individual performance score. For 2017, the individual performance scores and the Individual Performance Incentive for each of the Named Executive Officers are set forth below:

2017 Individual Performance Incentive Determination

|  |  |  |  |  |  |  |  |  |  |  | Individual |  |  |
|  |  |  | Individual Performance |  |  |  | Performance |  | Individual |

|  | Base |  | (as a % of Base Salary) |  | Performance |  | (as a % of |  | Incentive |
Named Executive Officer |  | Salary |  | Threshold |  | Target |  | Maximum |  | Score |  | Base Salary) |  | (in dollars) |
Mr. Lane |  | $ | 670,000 |  | 1 | % | 10 | % | 20 | % | 110.0 | % | 11.0 | % | $ | 73,700 |
Mr. George |  | $ | 426,000 |  | 1 | % | 10 | % | 20 | % | 20.0 | % | 2.0 | % | $ | 8,520 |
Mr. McKenna |  | $ | 351,000 |  | 1 | % | 10 | % | 20 | % | 132.5 | % | 13.3 | % | $ | 46,508 |
Ms. Shaeff |  | $ | 278,100 |  | 1 | % | 10 | % | 20 | % | 177.5 | % | 17.8 | % | $ | 49,363 |

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

Long‑term Incentives

In 2017, long-term incentive (“LTI”) grants provided by the Company consisted of (i) stock options, (ii) RSUs, and (iii) PSUs, which are denominated in dollar amounts but, once earned, are settled in shares of Common Stock based on the market value of the Company’s 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 performance compensation between the Company’s performance relative to certain comparable companies, the Company’s ongoing profitability, and the performance of the Company’s Common Stock. The Committee believes that these awards promote a long-term view and further align the executive officers’

30

Table of Contents

interests with those of our stockholders. The Committee adopted the current structure for LTI awards in 2012 based, in part, on input from Pearl Meyer.

Award Type |  | Description |  | Alignment with and Key Benefits to Stockholders
Stock Options |  | 30% of total LTI grant value |  |
|  | Vest ratably over three years |  | Inherently performance‑based
|  | Exercise price equal to the closing price on date of grant |  | Value contingent upon positive stock price performance
|  | No value to the executive unless stock price increases after the date of grant |  | 10‑year term encourages a focus on longer‑term performance
Restricted Stock Units (RSUs) |  | 30% of total LTI grant value |  | Value partially dependent upon stock price performance
|  | Vest ratably over three years |  | Enhances retention of executive talent
|  |  |  | Encourages long‑term stock ownership
Performance Stock Units (PSUs) |  | 40% of total LTI grant value (assuming target performance) |  | Performance‑contingent
|  | Vest following the end of a three‑year performance period contingent upon achievement of certain levels of performance |  | EPS performance goals reward focus on sustainable year-over-year profitability
|  | Dollar‑denominated awards Settled in shares based upon stock price following the end of the performance period |  | TSR performance goals reward focus on producing stockholder returns in excess of those for our peers
|  | Performance based upon: |  |
|  | EPS performance against budget (50%) |  |
|  | TSR performance against peers (50%) |  |

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 Named Executive Officer’s base salary to determine the total dollar amount of the award of LTI compensation to be granted to that Named Executive Officer each year, based on grant date values and, for PSUs, assuming target performance is achieved. The Committee determines these percentage levels by analyzing each Named Executive Officer’s tenure, responsibilities and professional experience and recommendations from Pearl Meyer based on market survey data as described above. For 2017, the following percentage of base salary was used for the Named Executive Officers to determine the grant date value of LTI awards: Mr. Lane,

31

Table of Contents

150% of base salary; Mr. George, 140% of base salary; Mr. McKenna, 100% of base salary; and Ms. Shaeff, 75% of base salary. Mr. Mylett was not granted LTI awards for 2017 due to his resignation effective in February 2017.

Once each Named Executive Officer’s total grant date value is determined, the number of RSUs and stock options 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. The number of stock options to be granted is determined by dividing the total dollar amount of the stock options to be granted by the estimated value of the options on the date of grant using a Black‑Scholes model. PSUs are denominated in dollars.

As an illustration, Mr. Lane’s 2017 award of LTI compensation was calculated as follows:

Total Amount of Award: 150% of base salary of $670,000 equals $1,005,000.

RSUs Awarded: 30% of $1,005,000 equals $301,500 in value of RSUs. $301,500 divided by $36.25 (the closing price of the Company’s Common Stock on the date of grant) equals 8,317 RSUs.

Stock Options Awarded: 30% of $1,005,000 equals $301,500 in value of stock options. $301,500 divided by approximately $11.60 (the approximate value of the stock options on the date of grant using a Black-Scholes valuation model) equals 25,988 stock options.

PSUs Awarded: 40% of $1,005,000 equals $402,000 in value of PSUs.

The table below sets forth the 2017 LTI compensation awards for each of the Named Executive Officers, other than Mr. Mylett:

Named Executive Officer |  | Base Salary |  | Salary Percentage for Calculating Plan Awards |  | Number of Stock Options Awarded |  | Number of RSUs Awarded |  | Dollar Value of PSUs Awarded (at target) |  | Value of Awards under Plan (at target) |
Mr. Lane |  | $ | 670,000 |  | 150 | % | 25,988 |  | 8,317 |  | $ | 402,000 |  | $ | 1,005,000 |
Mr. George |  | $ | 426,000 |  | 140 | % | 15,422 |  | 4,935 |  | $ | 238,500 |  | $ | 596,400 |
Mr. McKenna |  | $ | 351,000 |  | 100 | % | 9,076 |  | 2,904 |  | $ | 140,400 |  | $ | 351,000 |
Ms. Shaeff |  | $ | 278,100 |  | 75 | % | 5,393 |  | 1,726 |  | $ | 83,430 |  | $ | 208,575 |

PSU Design

Upon vesting, PSUs will be settled in shares of the Company’s Common Stock, with the number of such shares determined by dividing the dollar denomination of vested PSUs (which may be up to 200% of the original dollar denomination of such PSUs) by the market value of the Company’s Common Stock following the end of the applicable three-year performance period. PSUs are earned based on the two metrics set forth in the table below, both of which are measured over a three-year performance period, and earned PSUs vest in full upon certification of the performance metrics by the Compensation 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 budgeted EPS performance |  | 50 | %
Relative Total Shareholder Return |  | Company’s performance relative to identified peer group* |  | 50 | %

* For purposes of measuring the Company’s relative total shareholder return for awards granted in 2017, the identified group of comparable companies consists of: Matrix Service Company; Primoris Services Corporation; Tutor Perini Corporation; Stantec Inc.; Dycom Industries Inc.; MasTec, Inc.;

32

Table of Contents

Sterling Construction, Inc.; EMCOR Group Inc.; MYR Group, Inc.; Quanta Services, Inc.; Tetra Tech Inc.; Great Lakes Dredge & Dock Corporation; Granite Construction Incorporated; Layne Christensen Company; and NCI Building Systems Inc. Based on industry analysis and conversations with 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 Company’s Named Executive Officers.

EPS: The EPS measure compares the Company’s actual EPS performance against its budgeted EPS performance 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 the budgeted EPS 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 potential settlements range from 0% to 200% of the target award amount.

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

PSU Awards Vesting in 2016 and 2017

PSU awards granted in 2014 with a 2014-2016 performance period were settled in early 2017. The following table shows the EPS and TSR levels achieved over such awards’ three-year performance period and the payout factor (percentage of the target award earned) for these awards:

|  | 2014 |  | 2015 |  | 2016 |  | 3 Year Average |  | Payout factor (% of target) |
EPS |  | 83 | % | 178 | % | 126 | % | 129 | % | 200 | %
TSR |  | 33 | % | 93 | % | 20 | % | 49 | % | 98 | %

Table of Contents

PSU awards granted in 2015 with a 2015-2017 performance period were settled in early 2018. The following table shows the EPS and TSR levels achieved over such awards’ three-year performance period and the payout factor for these awards.

|  | 2015 |  | 2016 |  | 2017 |  | 3 Year Average |  | Payout factor (% of target) |
EPS |  | 178 | % | 126 | % | 96 | % | 133 | % | 200 | %
TSR |  | 93 | % | 20 | % | 87 | % | 67 | % | 167 | %

Rule of 75

The “Rule of 75” provides that if an executive 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 have been deemed to have satisfied the continuous employment requirement for any equity award to vest. Pursuant to the Rule of 75, all performance-based equity awards will continue to be earned only if the applicable performance measures are satisfied, 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, 2017, Mr. Lane was the only Named Executive Officer to satisfy 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 other similarly-sized and -situated companies. The plans offered to executive officers are broad‑based plans applicable 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 annual pay or up to the maximum allowed contribution pursuant to the Code.

Perquisites

The Company generally does not provide perquisites to the Named Executive Officers that are not provided to other employees. However, the Named Executive Officers are beneficiaries of 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

The Company’s 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 a 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 Company previously provided executive officers with so-called Section 280G gross-ups, but in 2013 decided to not offer this type of benefit on a go-forward basis with respect to newly-hired executive officers. 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 Guidelines

The Company’s stock ownership guidelines require 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 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 calculating this 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):

Level |  | Base Salary Multiple |
Chief Executive Officer |  | 5 |
Chief Operating Officer |  | 3 |
Chief Financial Officer |  | 3 |
General Counsel |  | 2 |
Chief Accounting Officer |  | 1 |

As of December 31, 2017, each of our executive officers was in compliance with the stock ownership guidelines.

Executive Compensation Recovery 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.

Anti‑Hedging/Pledging Policy

We prohibit our directors and executive officers from hedging their ownership of the Company’s stock, including trading in options, puts, calls, or other derivative instruments related to Company stock or debt. Directors and executive officers are prohibited from purchasing the Company’s stock on margin, borrowing against the Company’s stock held in a margin account, or pledging the Company’s stock as collateral for a loan.

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” policy; (iii) the Company’s required stock ownership guidelines; (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. For 2017 and prior years, this deduction limit did not apply to compensation that qualified as performance-based under Section 162(m). The performance-based compensation exception to Section 162(m) was repealed and certain other

35

Table of Contents

changes were made to Section 162(m), generally effective for taxable years beginning after December 31, 2017. As a result, compensation paid to certain current and former executive officers in excess of $1 million in a taxable year generally will not be deductible beginning in 2018 unless such compensation qualifies for transition relief applicable to legally-binding contracts that were in effect on November 2, 2017.The Committee takes into consideration the potential deductibility of the compensation as one of the factors to be considered when establishing the Company’s executive compensation program. However, 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 may, in its judgment, authorize compensation payments that are limited as to tax deductibility. The Committee will continue to monitor the effect of tax reform on the Company’s executive compensation program.

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.

The aggregate grant date fair value of the stock awards was computed in accordance with FASB ASC Topic 718. See Note 14 to the Consolidated Financial Statements included in our Annual Report on Form 10-K for the year ended December 31, 2017 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 performance awards is computed based on performance at the target level, the probable outcome of the performance conditions as of the date of grant. The aggregate grant date fair value will likely vary from the actual amount the Named Executive Officers receive 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 earned and vested, will be settled in the Company’s Common Stock based on the market value of the Company’s Common Stock following the applicable performance period. PSUs are earned if, and to the degree that, the Company meets certain objective, pre-established performance measures relating to total shareholder return compared to certain comparable companies and EPS performance 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 2017, assuming achievement of the highest level of performance, was $804,000 for Mr. Lane, $477,120 for Mr. George, $280,800 for Mr. McKenna, and $166,860 for Ms. Shaeff. The aggregate grant date fair value of the PSUs granted during 2016, assuming achievement of the highest level of performance, was $750,000 for Mr. Lane, $448,000 for Mr. George, $272,000 for Mr. McKenna, $162,000 for Ms. Shaeff, and $280,000 for Mr. Mylett.

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 2015-2017 performance period. The 3-year average performance payout factor for the EPS component of these awards was 2.00x. The 3-year average performance payout factor for the TSR component of these awards was 1.67x. For purposes of this table, the number of units has been determined by dividing the cash value of the awards earned based on actual performance by $43.65, the closing price of a share of the Company’s Common Stock on December 29, 2017, the last business day of 2017. 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 $42.50, the closing price of a share of the Company’s Common Stock on March 7, 2018, the date on which the performance was certified by the Compensation Committee.

| (3) |  | The market value is based on the closing price of a share of the Company’s Common Stock as of December 29, 2017 ($43.65), the last business day of 2017, for unvested RSUs, and is based on the actual dollar amount earned under the PSU awards for the 2015-2017 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 2016-2018 and 2017-2019 performance periods. 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 share price of a share of Common Stock on December 29, 2017 ($43.65), the last business day of 2017. 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 have earned under outstanding PSU awards for each of the 2016-2018 and 2017-2019 performance periods assuming achievement of maximum performance.

Potential Payments Upon Termination or Change in Control

Prior to March 26, 2008, the Company had included change in control and severance arrangements in the employment agreements with Messrs. Lane, and George, as well as Ms. Shaeff and Mr. McKenna. On March 26, 2008, the Compensation Committee concluded its plan to terminate all executive employment arrangements by requesting that all Named Executive Officers relinquish their rights pursuant to their employment agreements. As consideration, the Committee enacted an Executive Severance Policy and entered into a change in control agreement with each executive.

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 policy

41

Table of Contents

provides for the Company’s payment of the following lump‑sum amount if an executive’s employment is terminated by the Company without cause, and not due to death or disability:

| · |  | 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 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 otherwise designated by the 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 Company has also entered into change in control agreements with the Named Executive Officers that 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 the Named Executive Officers 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. On a going-forward basis, new change in control agreements will not include this feature. These agreements provide for the Company’s payment of the following lump‑sum amount to the Named Executive Officers upon a qualifying termination of employment following a change in control event:

| · |  | Two times the sum of current base salary plus bonus (i.e., the greater of the average 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 and objectives established for such bonus) for Messrs. Lane and George; and

| · |  | One times such amounts for Ms. Shaeff, and Mr. McKenna.

Under the change in control agreements, the Named Executive Officers 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 the event of 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, be deemed to have satisfied the continuous employment requirement for any equity awards held by them to vest. Pursuant to the Rule of 75, all performance-based equity awards will continue to be earned only if the applicable performance measures are satisfied, 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, 2017, Mr. Lane was the only Named Executive Officer to satisfy the Rule of 75. If Mr. Lane had retired on December 31, 2017, he would be deemed to have satisfied the continuous employment requirement for purposes of vesting in: (1) 18,955 RSUs, 10,322 of which would vest on April 1, 2018, 5,861 of which would vest on April 1, 2019, and 2,772 of which would vest on April 1, 2020; (2) 55,778 stock options, 11,518 of which would vest on April 1, 2018 (with an exercise price of $19.67), 18,272 of which would vest in equal parts on April 1, 2018 and April 1, 2019 (with an exercise price of $30.36), and 25,988 of which would vest in equal parts on April 1, 2018, April 1, 2019 and April 1, 2020 (with an exercise price of $36.25); and (3) if applicable performance measures are satisfied, PSUs granted in 2015 valued at $643,500, which reflects 200% EPS achievement and 167% TSR achievement, PSUs granted in 2016 with a target value of $375,000, and PSUs granted in 2017 with a target value of $402,000, each of which would vest in the year following the performance period, to the extent earned based on performance, on the date on which the performance is certified by the Compensation Committee.

Summary of Potential Payments

The following table provides the lump-sum payments that would have been made to each Named Executive Officer (other than Mr. Mylett) if his or her employment had been terminated on December 31, 2017 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. The following table provides the amounts that were actually paid to Mr. Mylett in connection with his resignation from employment effective February 1, 2017 pursuant to his Resignation and General Release Agreement with the Company.

James Mylett |  |  | — |  |  | — |  |  | — |  | $ | 1,130,541 |

| (1) |  | The Company maintains life insurance for each of the Named Executive Officers in an amount equal to the sum of 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. The amount listed in the table above is the amount that would be paid under the Executive Severance Policy, net of insurance proceeds.

| (2) |  | The Company maintains disability insurance for each of the Named Executive Officers in an amount equal to the sum of 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. The amount listed in the table above is the amount that would be paid under the Executive Severance Policy, 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 Mr. George; and one times such amounts for Mr. McKenna and Ms. 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—$24,054; Mr. George—$17,689; Mr. McKenna—$15,694; and Ms. Shaeff—$13,270. 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

43

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.

| (4) |  | Effective February 1, 2017, Mr. Mylett resigned from the Company. In connection with his resignation, the Company entered into a Resignation and General Release Agreement with Mr. Mylett, under which he received cash severance in the amount of $1,119,129 paid in four equal installments during 2017, and reimbursement of the Company portion of COBRA premiums for 12 months ($11,412). Mr. Mylett did not receive any severance benefits pursuant to the Executive Severance Policy, any annual incentive plan bonus for 2017, or any amounts in respect of equity awards granted to him that were not vested as of the date of his resignation.

The following table provides the lump-sum payout and value of the accelerated vesting of equity awards that would have been received by each Named Executive Officer (other than Mr. Mylett) if his or her employment had been terminated in a qualifying termination, as described above, in connection with a change in control occurring on December 31, 2017.

Julie S. Shaeff |  | $ | 500,944 |  | $ | 633,254 |  | $ | 0 |  | $ | 1,134,198 |

| (1) |  | Consists of two times the sum of current base salary plus bonus (i.e., the greater of the average incentive plan bonus paid during the last three years or the current annual incentive plan bonus for 2017) for Messrs. Lane and George; and one times such amounts for Ms. Shaeff and Mr. McKenna. 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 stock options is determined based on the difference between the exercise price of the stock options and the closing price of a share of Common Stock on December 29, 2017 ($43.65), the last business day of 2017. 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 our Common Stock on December 29, 2017. The value of PSUs for the 2015-2017, 2016-2018 and 2017-2019 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.

Additionally, 256,280 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 29, 2017, the last business day of 2017. The Company has no other securities to be issued upon exercise of outstanding options, warrants, or rights.

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 March 2018 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 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, Ernst & Young LLP, the audited financial statements of the Company for the year ended December 31, 2017. The committee discussed with Ernst & Young 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. 61, as amended (Communications with Audit Committees), relating to the conduct of the audit. The Audit Committee also has discussed with Ernst & Young LLP, the auditors’ independence from the Company and its management, including the matters in the written disclosures the committee received from the independent auditors as required by Independence Standards Board Standard No. 1 (Independence Discussions with Audit Committees), and 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, 2017 and for filing with the SEC.

OTHER INFORMATION

Compensation Committee Interlocks and Insider Participation

Messrs. Anderson, Bulls, Krusi, Myers, and Tang, none of whom is or was an officer or employee of the Company or any of our subsidiaries through 2017, served on the Compensation Committee during 2017. None of the Company’s executive officers serve on the board of directors or compensation committee, or any other committee serving an equivalent function, of another company that employs any member of the Board.

Section 16(a) Beneficial Ownership Reporting Compliance

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, 2017, 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 request by writing 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 nominee record holder, 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. This process is to be used for both approvals as well as ratifications under the policy.

Table of Contents

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.

From time to time, the Company or its subsidiaries may have employees who are related to our executive officers or directors. David Giardinelli, the brother of Alfred Giardinelli, one of our directors (until the Annual Meeting), was employed by a subsidiary of the Company as a salesman during the year ended December 31, 2017. In 2017, his total compensation did not meet the threshold requiring Audit Committee approval pursuant to our Related Person Transactions Policy or requiring disclosure under applicable SEC rules. Travis Giardinelli, the son of Alfred Giardinelli, was employed by a subsidiary of the Company as a salesman during the year ended December 31, 2017. In 2017, his total compensation did not meet the threshold requiring Audit Committee approval pursuant to our Related Person Transactions Policy or requiring disclosure under applicable SEC rules. Thomas Marnell, the brother-in-law of Brian Lane, our Chief Executive Officer and one of our directors, was employed by a subsidiary of the Company during the year ended December 31, 2017. In 2017, his total compensation did not meet the threshold requiring Audit Committee approval pursuant to our Related Person Transactions Policy or requiring disclosure under applicable SEC rules. Megan Shaeff, the daughter of Julie Shaeff, our Chief Accounting Officer, was employed as an intern of the Company during the summer of 2017. In 2017, her total compensation did not meet the threshold requiring Audit Committee approval pursuant to our Related Person Transactions Policy.

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

Interest of Certain Persons in Matters to Be Acted Upon

The Named Executive Officers and directors of the Company do not have any substantial interest in the matters to be acted upon at the Annual Meetings, other than in their roles as officers or directors of the Company.

Stockholder Proposals for 2019 Annual Meeting
