All stockholders are cordially invited to attend this meeting.

We have elected to adopt the U.S. Securities and Exchange Commission rule that allows companies to furnish their proxy materials over the Internet. As a result, we are mailing a Notice Regarding the Availability of Proxy Materials (the “Notice of Availability”) to our stockholders instead of a paper copy of this Proxy Statement and our 2021 Annual Report. The Notice of Availability contains instructions on how to access and review those documents over the Internet. We believe that this process will allow us to provide our stockholders with the information they need in a more timely manner, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials. Stockholders who receive a Notice of Availability by mail and would like to receive a printed copy of our proxy materials should follow the instructions for requesting such materials included on the Notice of Availability.

Your vote is very important to us. Whether or not you plan to attend the meeting in person, your shares should be represented and voted. To vote, please complete and return your proxy card, or vote by telephone or via the Internet by following the instructions on your Notice of Availability. Returning a proxy card or otherwise submitting your proxy does not deprive you of your right to attend the annual meeting and vote in person.

Annual Meeting of Stockholders

Proxy Statement

General Information

This Proxy Statement is furnished in connection with the solicitation of proxies by the Board of Directors (the “Board”) of Trex Company, Inc. (the “Company”, “we” or “our”) for use at the Company’s 2022 annual meeting of stockholders to be held at Trex University, 331 Apple Valley Road, Winchester, Virginia, on Thursday, May 5, 2022 at 9:00 a.m., local time. The purpose of the annual meeting and the matters to be acted upon are set forth in the accompanying notice of annual meeting.

Only stockholders of record at the close of business on March 9, 2022, the record date for the annual meeting (the “record date”), will be entitled to notice of and to vote at the annual meeting. As of February 28, 2022, we had 114,357,638 shares of common stock outstanding, which are our only securities entitled to vote at the annual meeting. Each share of common stock is entitled to one vote.

A list of stockholders entitled to vote at the annual meeting will be open to the examination of any stockholder, for any purpose germane to the meeting, during ordinary business hours for a period of ten days before the meeting at the Company’s offices at 160 Exeter Drive, Winchester, Virginia, and at the time and place of the meeting during the whole time of the meeting.

Notice of the Company’s annual meeting was mailed on or about March 22, 2022 to all stockholders as of the record date.

Those stockholders entitled to vote may vote their shares via the Proxy Card, or via the Internet, telephone or mail, following the instructions printed on the Notice of Availability.

Stockholders who receive a Notice of Availability and would like to receive a printed copy of our proxy materials should follow the instructions for requesting such materials included in the Notice of Availability.

From the date of the mailing of the Notice of Availability until the conclusion of the annual meeting, all of the proxy materials will be accessible on the Company’s website at www.trex.com/proxy.

Stockholders who execute proxies may revoke them by giving written notice to our Secretary any time before such proxies are voted. Attendance at the annual meeting shall not have the effect of revoking a proxy unless the stockholder so attending shall, in writing, so notify the Secretary at any time prior to the voting of the proxy at the annual meeting.

The Board does not know of any matter that is expected to be presented for consideration at the annual meeting, other than the election of three directors, a non-binding advisory vote on the compensation of our named executive officers, approval of the First Certificate of Amendment to the Trex Company, Inc. Restated Certificate of Incorporation to increase the number of authorized shares of common stock, $0.01 par value per share, from 180,000,000 to 360,000,000, and ratification of the appointment of our independent registered public accounting firm for the current fiscal year. However, if other matters properly come before the annual meeting, the persons named in the accompanying proxy intend to vote thereon in accordance with their judgment.

We are not engaging any company for the purpose of proxy solicitation in conjunction with this Proxy Statement. We will bear the cost of the annual meeting and the cost of soliciting proxies, including the cost of mailing any proxy materials. In addition to solicitation by mail, our directors, officers and regular employees (who will not be specifically compensated for such services) may solicit proxies by telephone or otherwise. Arrangements will be made with brokerage houses and other custodians, nominees and fiduciaries to forward proxies and proxy material to their principals, and we will reimburse them for their expenses. In addition, we have retained Broadridge Financial Solutions, Inc., or Broadridge, to assist in the mailing, collection, and administration of the proxy.

The 2021 Annual Report to stockholders and the 2021 Form 10-K are not proxy soliciting materials.

All proxies received pursuant to this solicitation will be voted except as to matters where authority to vote is specifically withheld. Where a choice is specified as to the proposal, proxies will be voted in accordance with such specification. If no instructions are given, the persons named in the proxy intend to vote:

A majority of the outstanding shares of common stock entitled to vote on the record date, whether present in person or represented by proxy, will constitute a quorum for the transaction of business at the annual meeting and any adjournment or postponement thereof. Abstentions and broker non-votes (which occur with respect to any proposal when a broker holds shares of a customer in its name and is not permitted to vote on that proposal without instruction from the beneficial owner of the shares and no instruction is given) will be counted as present or represented for purposes of establishing a quorum for the transaction of business.

The following vote shall be required for approval of each matter:

Security Ownership

The following table presents, as of February 28, 2022, information based upon the Company’s records and filings with the U.S. Securities and Exchange Commission (“SEC”) regarding beneficial ownership of its common stock by the following persons:

∎  each person known to the Company to be the beneficial owner of more than 5% of the common stock;

∎  each director and each nominee to the Board;

∎  each executive officer of the Company named in the Summary Compensation Table following the Compensation Discussion and Analysis section of this Proxy Statement; and

∎  all directors and executive officers of the Company as a group.

As of February 28, 2022, there were 114,357,638 shares of common stock outstanding.

The following information has been presented in accordance with SEC rules and is not necessarily indicative of beneficial ownership for any other purpose. Under SEC rules, beneficial ownership of a class of capital stock as of any date includes any shares of such class as to which a person, directly or indirectly, has or shares voting power or investment power as of such date and also any shares as to which a person has the right to acquire such voting or investment power as of or within 60 days after such date through the exercise of any stock option, stock appreciation right, warrant or other right, without regard to whether such right expires before the end of such 60-day period or continues thereafter. If two or more persons share voting power or investment power with respect to specific securities, all of such persons may be deemed to be the beneficial owners of such securities.

Election of Directors

(Proposal 1)

The Company’s Restated Certificate of Incorporation, as amended, provides that the Board is to be divided into three classes of directors, with the classes to be as nearly equal in number as possible. The current terms of office of the three current classes of directors expire at this annual meeting, at the annual meeting of stockholders in 2023 and at the annual meeting of stockholders in 2024, respectively. Upon the expiration of the term of office of each class, the nominees for such class will be elected for a term of three years to succeed the directors whose terms of office expire.

In accordance with the recommendation of the Nominating/Corporate Governance Committee, Mr. Fairbanks, Mr. Golden, and Ms. Juster have been nominated by the Board for election to the class with a three-year term that will expire at the annual meeting of stockholders in 2025. Mr. Fairbanks is being renominated to the class of directors whose term expires in 2025 to keep the number of directors in each class as nearly equal in number as possible after Mr. Posey retires from the Board effective as of the 2022 Annual Meeting of Shareholders. These nominees are incumbent directors.

Approval of the nominees requires the affirmative vote of a majority of the votes cast in favor of such nominee at the annual meeting. The term “Majority” for purposes of election of directors means that a nominee receives more votes in favor of such nominee then are cast against such nominee by the holders of shares present in person or represented by proxy and entitled to vote at the Annual Meeting. Abstentions and broker non-votes will have no effect on the election of directors. Brokers may vote their shares in favor of directors if they have voting instructions from the beneficial owners of the shares. Unless authority to do so is withheld, it is the intention of the persons named in the proxy to vote such proxy FOR the election of each of the nominees. If any of the nominees should become unable or unwilling to serve as a director, the persons named in the proxy intend to vote for the election of such substitute nominee for director as the Board may recommend. It is not anticipated that any of the nominees will be unable or unwilling to serve as a director.

The Board unanimously recommends that the stockholders of the Company vote FOR the election of the nominees to serve as directors.

Corporate Governance

The Board currently consists of ten directors. Mr. Posey will retire from the Board effective as of the 2022 Annual Meeting of Shareholders at which time the Board intends to decrease the size of the Board from ten directors to nine directors.

The Board has three standing committees: the Audit Committee, the Compensation Committee and the Nominating/Corporate Governance Committee. During the Company’s 2021 fiscal year, the Board held five meetings, the Audit Committee held four meetings, the Compensation Committee held five meetings, and the Nominating/Corporate Governance Committee held five meetings. During 2021, each director attended at least 75% of the aggregate of the total number of meetings of the Board and of each committee of the Board on which such director served.

It is the Company’s policy that all directors should attend annual meetings of the Company’s stockholders. All of the directors attended the annual meeting in May 2021.

The Board does not have a strict retirement age for directors. However, the Board does believe that once a director attains a certain age, the Board should carefully consider whether such director’s continued service on the Board is in the best interests of the Company. The Company’s Corporate Governance Principles provide that at the adjournment of each annual meeting of stockholders, any director who is then age 75 or older shall tender his or her resignation to the Board, at which time the Board may elect to either accept such resignation or request that such director continue to serve on the Board.

Board Leadership Structure.    Our Board is currently led by a non-executive Chairman, Mr. Cline, who retired as the Company’s President and Chief Executive Officer on April 28, 2020, and a non-executive Vice Chairman, Mr. Kaplan, who retired as the Company’s President and Chief Executive Officer on August 17, 2015. Our Board determined that retaining Mr. Cline as Chairman and Mr. Kaplan as Vice Chairman was in the best interests of the Company because it allows the Company to benefit from Mr. Cline’s and Mr. Kaplan’s significant experience and accumulated expertise in the Company’s industry and the Company’s internal policies, practices and procedures to effectively and expertly guide the Board. Mr. Cline’s and Mr. Kaplan’s familiarity with the Company’s executives reinforces that the Board and executives will operate with continuity and common purpose. The Board determined that having Mr. Cline as Chairman and Mr. Kaplan as Vice Chairman will allow Mr. Fairbanks, the Company’s President and Chief Executive Officer, to focus on executing the Company’s strategy and manage operations and performance. The Board is further comprised of a Lead Independent Director, an independent Audit Committee Chairman, an independent Compensation Committee Chairman, and an independent Nominating/ Corporate Governance Committee Chairman. These independent positions align with the Company’s corporate governance policies and practices and assure adequate independence of the Board.

Ms. Robinson served as Lead Independent Director between January 1, 2021 and May 5, 2021. Mr. Posey currently serves as Lead Independent Director for a term beginning on May 6, 2021 and ending on the date of the 2022 Annual Meeting. Both Ms. Robinson and Mr. Posey are experienced former chief executive officers. (For additional information regarding Ms. Robinson’s and Mr. Posey’s professional experience, please see “Election of Directors (Proposal 1”).” Pursuant to the Company’s Corporate Governance Principles, the responsibilities of the Lead Independent Director include: presiding at executive sessions of the independent directors; presiding at Board meetings in the absence of the Chairman and Vice Chairman; making recommendations and consulting with management with regard to Board meeting agendas, materials and schedules; and serving as a liaison between the independent directors and members of senior management.

Director Independence.    The Board has affirmatively determined that all of the current directors, other than Mr. Cline, who is the Company’s current Chairman, and Mr. Fairbanks, who is the Company’s current President and Chief Executive Officer, are “independent” of the Company within the independence guidelines governing

companies listed on the New York Stock Exchange (“NYSE”). For a director to be “independent” under the NYSE guidelines, the Board must affirmatively determine that the director has no material relationship with the Company, either directly or as a partner, stockholder or officer of an organization that has a relationship with the Company.

The Board has adopted the following categorical standards of independence to assist it in determining whether a director has a material relationship with the Company. The following relationships between a director and the Company will not be considered material relationships that would preclude a finding by the Board that the director is independent under the NYSE guidelines:

∎  employment of the director or the director’s immediate family member by another company that makes payments to, or receives payments from, the Company or any of its subsidiaries for property or services in an amount which, in any single fiscal year, does not exceed the greater of $1,000,000 or 2% of such other company’s consolidated gross revenues; and

∎  a relationship of the director or the director’s immediate family member with a charitable organization, as an executive officer, board member, trustee or otherwise, to which the Company or any of its subsidiaries has made charitable contributions of not more than $50,000 annually in any of the last three years.

Furthermore, the Board has also determined, consistent with NYSE guidelines, a director is not independent if:

Consistent with the NYSE guidelines, the Company’s corporate governance principles require the Company’s non-management directors to meet at least once each quarter without management present and, if the group of non-management directors includes any director who is not independent under NYSE guidelines, to meet at least once each year with only the independent directors present. The Company’s non-management directors, all of whom are independent under NYSE guidelines other than Mr. Cline, held five executive sessions in 2021. The independent directors held one executive session in 2021. Mr. Cline, as Chairman, acted as presiding director for each such executive session of non-management directors, and Mr. Posey, as Lead Independent Director, acted as presiding director for the executive session of independent directors.

Our Board has three standing committees:

∎  Compensation Committee, chaired by Mr. Golden; and

∎  Nominating/Corporate Governance Committee, chaired by Mr. Posey between January 1, 2021 and May 5, 2021 and by Ms. Robinson after such date.

Each of these committees plays an important role in the governance and leadership of our Board and each is chaired by an independent director with significant business experience.

Audit Committee.    During 2021, the Audit Committee of the Board was composed of five non-employee directors who meet the independence and expertise requirements of the NYSE listing standards: Mr. Gratz, who was the Chairman, Ms. Lovett, Mr. Posey, Ms. Robinson, and Mr. Volas. Pursuant to SEC rules, the Board has determined that Mr. Gratz and Mr. Volas are “audit committee financial experts,” as such term is defined for purposes of Item 407 of Regulation S-K promulgated by the SEC, and are independent of management.

A current version of the Nominating/Corporate Governance Committee charter is available on the Company’s website at www.trex.com/our-company/corporate-governance/committees-charters/.

Our Board recognizes the importance of effective risk oversight in running a successful business and in fulfilling its fiduciary responsibilities to the Company and its stockholders. While the CEO and other members of our senior leadership team are responsible for the day-to-day management of risk, our Board is responsible for ensuring that an appropriate culture of risk management exists within the Company and for setting the right “tone at the top,” overseeing our aggregate risk profile, and assisting management in addressing specific risks, such as strategic and competitive risks, financial risks, brand and reputation risks, legal risks, regulatory risks, and operational risks. In 2021, the Board also was advised by and consulted with senior management with respect to risks related to the COVID-19 pandemic, and its effects on the Company.

The Board believes that its current leadership structure best facilitates its oversight of risk by combining independent leadership, through an independent Lead Independent Director, independent board committees, and majority independent board composition, with an experienced Chairman and Vice Chairman and an experienced CEO who each have extensive knowledge of our business, history, and the complex challenges we face. The CEO’s in-depth understanding of these matters and involvement in the day-to-day management of the Company uniquely positions him to promptly identify and raise key business risks to the Board, call special meetings of the Board when necessary to address critical issues, and focus the Board’s attention on areas of concern. The Chairman, Vice Chairman, Lead Independent Director, independent committee chairs and other directors also are experienced executives who can and do raise issues for Board consideration and review, and are not hesitant to challenge management. The Board believes there is a well-functioning and effective balance between the Chairman, Vice Chairman, Lead Independent Director, independent board committees, independent board members, and the CEO, which enhances risk oversight.

The Board exercises its oversight responsibility for risk both directly and through its three standing committees. Throughout the year, the Board and each committee spend a portion of their time reviewing and discussing specific risk topics. The full Board is kept informed of each committee’s risk oversight and related activities through regular attendance at all committee meetings by all directors. Strategic, operational and competitive risks also are presented and discussed at the Board’s quarterly meetings, and more often as needed. On at least an

annual basis, the Board conducts a review of our long-term strategic plans and members of senior management report on our top risks and the steps management has taken or will take to mitigate these risks. At each quarterly meeting, or more often as necessary, our CEO provides written and/or oral reports to the Board on the critical issues we face, and each officer reports on recent developments in their respective operating area. These reports include a discussion of business risks as well as a discussion regarding enterprise risk. In addition, at each quarterly meeting, or more often as necessary, the Senior Vice President, Chief Legal Officer and Secretary (“CLO”) as well as the General Counsel update the Board on material legal and regulatory matters.

The Audit Committee is responsible for reviewing the framework by which management discusses our risk profile and risk exposures with the full Board and its committees. The Audit Committee meets regularly with our CFO, independent registered public accounting firm, internal auditor, CLO, General Counsel, and other members of senior management to discuss our major financial risk exposures, financial reporting, internal controls, credit and liquidity risk, compliance risk, and key operational risks. The Audit Committee meets regularly in separate executive sessions with the independent registered public accounting firm and internal auditor, as well as with committee members only, to facilitate a full and candid discussion of risk and other issues.

The Compensation Committee is responsible for overseeing human capital and compensation risks, including evaluating and assessing risks arising from our compensation policies and practices and ensuring executive compensation is aligned with performance. The Compensation Committee is also charged with monitoring our incentive and equity-based compensation plans, including employee benefit plans, reviewing and retaining compensation advisers, and considering the results of the non-binding advisory say-on-pay vote and determine what adjustments, if any, are necessary or appropriate for the Company to make to its compensation policies and practices in light of the results of such vote. The Compensation Committee meets regularly with the CLO and also the General Counsel and other executive officers as well as in separate sessions with the Company’s external compensation consultant to facilitate a full and candid discussion of executive performance and compensation.

The Nominating/ Corporate Governance Committee oversees risks related to our overall corporate governance, including Board and committee composition, Board size and structure, Board compensation, director independence, our corporate governance profile and ratings and ESG-related strategies, initiatives and policies. The Committee also is actively engaged in overseeing risks associated with succession planning for the Board and management.

The Board of Directors, its committees and the Company’s management recognize the importance of environmental, social and governance (“ESG”) matters and how they impact our stakeholders. During 2021, the Company assigned oversight of ESG-related initiatives and performance to the Nominating/Corporate Governance Committee and continued its focus on several ESG initiatives that matter to our customers, employees, communities, stockholders and the environment. We believe appropriately responding to ESG issues is an important component of corporate social responsibility and comprehensive fiscal management. In light of the continued importance surrounding ESG matters, the Company is active in establishing and improving programs, practices and policies to maximize the benefit to the Company, our stockholders, employees, customers and the communities we impact. We believe that strong ESG programs and practices are critical to attracting the best talent, executing on our strategies, maintaining a robust supplier and channel partner base, and innovating to meet our consumers’ evolving expectations.

The Company’s policies, practices and programs include engagement with external stakeholders to learn about their priorities and get their feedback; coordination of relevant company projects and initiatives; and alignment with the Company’s strategies and implementation.

Further, the Board and its committees review and discuss with management matters related to human capital management, including the Company’s commitments and progress on diversity, equity and inclusion, employee engagement, compensation and benefits, business conduct and compliance, and executive succession planning. During 2021, the Board and its committees also reviewed and discussed with management the impact of the COVID-19 pandemic on the Company’s employees, supply chain, and business, and management’s strategies and initiatives to respond to, and mitigate, adverse impacts, including enhanced health and safety measures for the Company’s workforce.

We are committed to conducting operations and activities in a manner that provides and maintains safe and healthy working conditions, protects the environment, and conserves natural resources. In meeting this commitment, it is our policy that no employee shall engage in any conduct that violates any environmental, health or safety law or is otherwise inconsistent with the health and safety needs of our employees and the environmental needs of our communities. We are also committed to the continual improvement of our environmental management systems, our environmental, health and safety programs, and to the prevention of pollution.

On June 28, 2021 the Company published its third annual ESG Report that highlighted several achievements including:

The Company is committed to continuing its ESG commitment and will continue its communications with customers, employees, communities and stockholders regarding its ESG initiatives in the upcoming 2021 ESG Report. A copy of the Company’s current ESG report is available on the Company’s website at www.trex.com/why-trex/esg.

In connection with the Company’s ESG efforts, in addition to our Code of Conduct and Ethics, the Company has adopted a Human Rights Policy, a Vendor and Customer Code of Conduct and Ethics, an Environmental Policy and an Occupational Health and Safety Policy. A current version of each of these policies is available on the Company’s website at www.trex.com/our-company/.

No member of the Compensation Committee was an officer or employee of the Company or any subsidiary of the Company during 2021. There are no interlock relationships as defined in the applicable SEC rules.

The Board has adopted a director nominations policy (the “nominations policy”). The purpose of the nominations policy is to set forth the process by which candidates for directors are selected. The nominations policy is administered by the Nominating/Corporate Governance Committee of the Board.

The Board does not currently prescribe any minimum qualifications for director candidates. Consistent with the criteria for the selection of directors approved by the Board, the Nominating/Corporate Governance Committee will take into account the Company’s current needs and the qualities needed for Board service, including experience and achievement in business, finance, technology or other areas relevant to the Company’s activities; reputation, ethical character and maturity of judgment; diversity of viewpoints, backgrounds and experiences; absence of conflicts of interest that might impede the proper performance of the responsibilities of a director; independence under SEC and NYSE rules; service on other boards of directors; sufficient time to devote to Board matters; ability to work effectively and collegially with other Board members; and diversity. In considering the diversity of candidates, the Committee considers an individual’s background, viewpoints, professional experience, education and skill, race, ethnicity, gender, age and/or national origin. In the case of incumbent directors whose terms of office are set to expire, the Nominating/Corporate Governance Committee will review such directors’ overall service to the Company during their term, including the number of meetings attended, level of participation, quality of performance and any transactions of such directors with the Company during their term. For those potential new director candidates who appear upon first consideration to meet the Board’s selection criteria, the Nominating/Corporate Governance Committee will conduct appropriate inquiries into their background and qualifications and, depending on the result of such inquiries, arrange for in-person meetings with the potential candidates.

The Nominating/Corporate Governance Committee may use multiple sources for identifying director candidates, including its own contacts and referrals from other directors, members of management, and the Company’s advisers. The Nominating/Corporate Governance Committee has used in the past, and may use in the future, the services of an executive search firm to help identify candidates for directors who meet the qualifications outlined above. The search firm screens the candidates, conducts reference checks, prepares a biography of each candidate for committee review and assists in arranging interviews.

The Committee will also consider director candidates recommended by stockholders and will evaluate such director candidates in the same manner in which it evaluates candidates recommended by other sources. In making recommendations for director nominees for the annual meeting of stockholders, the Nominating/Corporate Governance Committee will consider any written recommendations of director candidates by stockholders received by the Secretary of the Company no later than 120 days before the anniversary of the previous year’s annual meeting of stockholders. Recommendations must include the candidate’s name and contact information and a statement of the candidate’s background and qualifications, and must be mailed to Trex Company, Inc., 160 Exeter Drive, Winchester, Virginia 22603-8605, Attention: Secretary.

The nominations policy is intended to provide a flexible set of guidelines for the effective functioning of the Company’s director nominations process. The Nominating/Corporate Governance Committee intends to review the nominations policy as it considers advisable and anticipates that modifications may be necessary from time to time as the Company’s needs and circumstances evolve, and as applicable legal or listing standards change. The Nominating/Corporate Governance Committee may amend the nominations policy at any time.

The Company’s bylaws provide that any stockholder wishing to nominate persons for election as directors at an annual meeting must deliver to the Secretary of the Company at the Company’s principal office in Winchester, Virginia a written notice of the stockholder’s intention to make such a nomination. The stockholder generally is required to furnish the notice no earlier than 120 days and no later than 90 days before the first anniversary of the preceding year’s annual meeting. The notice must contain the information required by the bylaws.

The Board welcomes communications from its stockholders and other interested parties and has adopted a procedure for receiving and addressing those communications. Security holders and other interested parties may communicate any concerns they may have about the Company directly and confidentially to either the full Board or the non-management directors as a group, or an individual director, by writing to: “Board of Directors” or “Non-Management Directors” or Name of Individual Director, Trex Company, Inc., 160 Exeter Drive, Winchester, VA 22603-8605, Attention: Secretary, or by calling the Company’s Governance Hotline (800-719-4916). An independent third-party vendor maintains the Governance Hotline, which is available 24 hours a day, 365 days a year. A caller wishing to be identified may indicate his or her name in the message. All calls are forwarded to both the CLO and CFO. The Secretary then reviews and forwards all communications to the Board member or members that the caller designates, except for those communications that are outside the scope of Board matters or duplicative of other communications previously forwarded to the intended recipients. The Secretary will retain copies of all communications and maintain a record of whether the communications were forwarded and, if not, the reason why not.

Any individual, whether an employee or third party, may report to the Audit Committee any information relating to questionable accounting, internal accounting controls and auditing matters by writing to Trex Company, Inc., Audit Committee Chairman, c/o Woods Rogers PLC, 901 East Byrd Street, Suite 1550, Richmond, VA 23219, or by calling the Company’s Governance Hotline. As stated above, an independent third-party vendor maintains the Governance Hotline. A caller wishing to be identified may indicate his or her name in the message. All calls are forwarded to the Chairman of the Audit Committee. If anyone wants to submit relevant records, they should be mailed to the above address.

We proactively engage with shareholders and other stakeholders throughout the year to learn their perspectives on significant issues, including company performance and strategy, corporate governance, executive compensation, and environmental, social, and governance (ESG) topics. This engagement helps us better understand shareholder priorities and perspectives, gives us an opportunity to elaborate upon our initiatives and practices, and fosters constructive dialogue. We take feedback and insights from our engagement with shareholders and other stakeholders into consideration as we review and evolve our practices and disclosures, and further share them with our Board as appropriate.

Section 16(a) of the Securities Exchange Act of 1934 requires the Company’s directors and executive officers and persons who own more than 10% of the Company’s common stock to file with the SEC and the NYSE initial reports of ownership and reports of changes in ownership of common stock and other equity securities of the Company. The reporting persons are required by rules of the SEC to furnish the Company with copies of all Section 16(a) reports they file. Based solely upon a review of Section 16(a) reports furnished to the Company for fiscal 2021 or written representations that no other reports were required, the Company believes that the foregoing reporting persons complied with all filing requirements for fiscal 2021.

We have adopted a Code of Conduct and Ethics, which is applicable to all of our directors, officers and employees, including our CEO and CFO. We make available on our web site, at https://www.trex.com/our-company/corporate-governance/, and in print, to any stockholder who requests them, copies of our Code of Conduct and Ethics, our Bylaws, our Corporate Governance Principles and the Charters of each standing committee of our Board. Requests for copies of these documents should be directed to Secretary, Trex Company, Inc., 160 Exeter Drive, Winchester, Virginia 22603-8605. To the extent required by SEC rules, we intend to disclose any amendments to our Code of Conduct and Ethics, and any waiver of a provision of the code with respect to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions, on our web site referred to above within four business days following any such amendment or waiver, or within any other period that may be required under SEC rules from time to time.

Non-Employee Director Compensation

Non-employee directors of the Company receive cash and stock-based compensation under the Trex Company, Inc. Amended and Restated 1999 Incentive Plan for Outside Directors (“Outside Director Plan”). The Outside Director Plan is administered by the Nominating/Corporate Governance Committee of the Board. The Outside Director Plan provides that all equity grants issued under such Plan are issued pursuant to the 2014 Stock Incentive Plan, which was approved by stockholders at the Company’s 2014 annual meeting.

The Nominating/Corporate Governance Committee is responsible for making recommendations to the Board regarding non-employee director compensation. In accordance with this authority, the Nominating/Corporate Governance Committee utilizes the Compensation Committee’s independent compensation consultant, Korn/Ferry International (“KF”), to advise the Nominating/Corporate Governance Committee on matters related to director compensation.

The Company’s director compensation program was reviewed by KF in February 2021 and February 2022 relative to the Company’s peer group. The Company’s peer group is reviewed by KF prior to each compensation review, and in July 2020, KF provided the Nominating/Corporate Governance Committee (with respect to director compensation) and the Compensation Committee (with respect to officer compensation) a set of considerations for change, including proposed additions and deletions to the peer group. (See discussion in Compensation Discussion and Analysis under the “How Do We Determine Executive Pay?” for further discussion on the changes to the Company’s peer group.)

The peer group approved by both the Nominating/Corporate Governance Committee and the Compensation Committee, and utilized by KF for the director compensation study, is as follows:

The KF review indicated that the non-employee directors’ total annual compensation (consisting of cash and equity-based compensation) in February 2021 was approximately 82% of the median of the peer group (assuming a hypothetical director serves as a member of the Audit Committee and the Compensation Committee). The Nominating/Corporate Governance Committee, desiring that non-employee directors’ total annual compensation more closely align with the peer group, recommended to the Board, and the Board approved on February 17, 2021 and February 23, 2022, increases in total annual compensation. For the hypothetical director referred to above, the total annual compensation was increased from $203,750 to $222,500, which equates to approximately 100% of the median of the peer group.

The elements of the non-employee director compensation package under the Outside Director Plan, as modified effective February 23, 2022, are as follows:

∎  Upon initial appointment to the Board, non-employee directors receive awards of options, stock appreciation rights (“SARs”), restricted shares, restricted stock units or any combination thereof (as determined by the Nominating/Corporate Governance Committee) valued at $55,000.

∎  For service on the Board, each non-employee director receives an annual fee of $82,500, and an annual award of options, SARs, restricted shares, restricted stock units or any combination thereof (as determined by the Nominating/Corporate Governance Committee) valued at $120,000.

∎  Any non-employee director who serves as Chairman of the Board will receive an additional $85,000 annually, as Vice Chairman of the Board will receive an additional $55,000 annually, and as Lead Independent Director will receive an additional $25,000 annually.

∎  The chairman of each committee receives an annual committee fee of $20,000, and each member of a committee other than the chairman receives an annual committee fee of $10,000.

∎  The annual director fee and the annual committee fees are paid in four equal quarterly installments in arrears on the first business day following each quarter of the fiscal year in which the eligible director completes board or committee service. Such fees are paid in the form of cash, provided that a director may elect to receive all or any portion of such fees in the form of a grant of options, SARs, restricted shares, restricted stock units or any combination thereof (as determined by the Nominating/Corporate Governance Committee). The fiscal year of the Outside Director Plan is July 1 through June 30.

∎  The annual grants of equity are made in arrears on the date of the first regularly scheduled Board meeting after June 30 of each year.

∎  All grants of restricted shares or restricted stock units vest one year after grant provided that the grants will immediately vest in the event of death, disability, retirement, or termination in connection with a change in control. All grants of SARs or stock options vest immediately upon grant and have a term of ten years (provided that the term is extended for one year if the director dies during the tenth year of the SAR or stock option term). Upon the termination of a non-employee director’s service for any reason (other than for cause), the director will have the right, at any time within five years after the date of termination of service and before the termination of the SAR or stock option, to exercise any SAR or stock option held by the director on the service termination date.

∎  All fees described above paid in arrears are pro-rated for any partial periods served.

The Nominating/Corporate Governance Committee has elected to use restricted stock units as the form of equity described above.

The Outside Director Plan is designed to deliver compensation approximately 46% in cash and 54% in equity (assuming a director does not elect to receive additional equity in lieu of cash, as described above), with the objective of appropriately balancing the pay of non-employee directors for their service while linking their compensation closely to returns to stockholders through the potential for enhanced value from future stock price appreciation. Directors are also reimbursed for actual travel expenses.

The Company does not provide pensions, medical benefits or other benefit programs to non-employee directors.

In 2013, the Board adopted Stock Ownership Guidelines applicable to non-employee directors, pursuant to which each non-employee director is required to own and hold, as a minimum, that number of shares of the Company’s common stock having a market value of at least 3 times the director’s annual cash retainer. For purposes of the guidelines, common stock includes shares of common stock no matter how acquired (i.e., vesting of restricted shares or restricted stock units, or purchased on the open market), and unvested restricted shares and restricted stock units. Directors have 5 years from the adoption of the guidelines or 5 years from becoming a director, whichever occurs later, to comply with the ownership requirements. Other than Ms. Lovett who joined the Board on March 8, 2021, each director meets the current minimum requirements.

In 2013, the Board also adopted, on a voluntary basis and in advance of final Dodd-Frank Act hedging rules, an Anti-Hedging and Anti-Pledging Policy that applies to non-employee directors. This policy prohibits our directors from purchasing any financial instrument or entering into any transaction that is designed to hedge or offset any decrease in the market value of Company equity (including, but not limited to, prepaid variable forward contracts, equity swaps, collars, or exchange funds), or pledging, hypothecating, or otherwise encumbering Company equity as collateral for indebtedness.

(See discussion in Compensation Discussion and Analysis under the “Stock Ownership Guidelines” and “Anti-Hedging and Anti-Pledging Policy” sections under “Additional Information on Our Program” for discussion of the Stock Ownership Guidelines and Anti-Hedging and Anti-Pledging Policy as applicable to our named executive officers.)

It also provides an overview of our executive compensation philosophy and why we believe the program is appropriate for the Company and its stockholders. Finally, we discuss the Compensation Committee’s methodology for determining appropriate and competitive levels of compensation for the named executive officers. Details of compensation paid to the named executive officers can be found in the tables below.

Our executive compensation program is intended to align our named executive officers’ interests with those of our stockholders by rewarding performance that meets or exceeds the goals the Board and the Compensation Committee establish with the objective of increasing stockholder value. In line with our pay-for-performance philosophy, the total compensation received by our named executive officers will vary based on individual and corporate performance measured against annual and long-term performance goals. Our named executive officers’ total compensation is comprised of a mix of base salary, annual cash incentive compensation and long-term equity incentive compensation.

The Company provides its stockholders the opportunity to cast an annual non-binding advisory vote on executive compensation (a “say-on-pay proposal”). The Company and the Company’s Compensation Committee consider the outcome of the Company’s say-on-pay proposal when making future compensation decisions for the executive officers of the Company. In connection with the Company’s 2021 annual meeting of stockholders, the proposal to approve the executive compensation of the Company’s executive officers named in the Company’s Proxy Statement dated March 23, 2021 received 90,343,066 votes in favor, or 92.7% of votes cast. Although these votes are advisory (and therefore not binding on the Company), the Company, the Compensation Committee and the Board carefully review these results each year and consider them, along with other communications from stockholders relating to our compensation practices, in making future compensation decisions for executive officers of the Company.

What person or group is responsible for determining the compensation levels of named executive officers?

The Role of the Compensation Committee. The Compensation Committee, pursuant to its charter, reviews, determines and approves the compensation, including base salary, and annual and long-term incentive compensation, of the Company’s CEO, the other named executive officers, as well as the other officers. Additionally, the Compensation Committee administers the Company’s employee benefit programs, including its 2014 Stock Incentive Plan, 1999 Employee Stock Purchase Plan, annual cash incentive plan, and other incentive compensation plans, benefit plans and equity-based plans.

The Role of Consultants. The Compensation Committee has the authority to retain and terminate any third-party compensation consultant and to obtain advice and assistance from internal and external legal, accounting and other advisers. The Compensation Committee has the authority to compensate its outside advisers without obtaining approval of the Board. In accordance with this authority, the Compensation Committee retained Korn/Ferry International (“KF”) in 2021 as the committee’s independent compensation consultant to advise the Compensation Committee on matters related to CEO and other officer compensation. The Compensation Committee assessed KF’s work as required under rules of the SEC and concluded that it did not raise any conflicts of interest and that KF was independent within the NYSE’s listing standards.

The consultant’s assignments are determined by the chairman of the Compensation Committee. At the request of the chairman, the current consultant assists in developing the peer group of companies and compensation surveys to be used for the competitive analyses, prepares the market analysis of named executive officer compensation, prepares a financial analysis of the Company’s performance vis-à-vis the peer group and analyzes the relationship between CEO pay and company performance, constructs market competitive ranges of pay opportunity for base salaries, annual cash incentive compensation targets, and long-term equity incentive awards for named executive officers, and reviews the annual cash incentive compensation and long-term equity incentive plans for linkage to key business objectives and company performance. The consultant advises the Compensation Committee as to the compensation of executive officers of the Company, but does not recommend any specific pay level changes for executive officers.

Total fees paid to KF for services performed during 2021 relating to executive compensation were $24,645. During 2021, KF also provided talent acquisition (professional search) consulting services and services related to an employee engagement survey. Management interviewed a number of consultants, but concluded that KF should be retained because they had a more robust process than the other consultants, and because of their intimate familiarity with the Company’s culture and baseline leadership inventory, the depth of their approach to understand the Company’s strategy prior to the creation of competencies and role profiles, and their ability to customize and adapt as the Company advanced through the program. The fees paid by the Company to KF for such services performed during 2021 were $108,695. The decision to retain KF to provide these additional services was approved by the Nominating/Corporate Governance Committee and the Board.

The Role of Executives. The Company’s CEO, Senior Vice President, Chief Legal Officer and Secretary (“CLO”), and Vice President, Human Resources (“VP-HR”) are actively involved in the executive compensation process. Historically, the CEO reviews the performance of each of the named executive officers (other than his own performance) and, within the defined program parameters, recommends to the Compensation Committee base salary increases and annual cash incentive compensation and long-term equity incentive awards for such individuals. He provides the Compensation Committee with both annual and long-term recommended financial performance goals for the Company that are used to link pay with performance. The CEO also provides his views to the Compensation Committee with respect to the executive compensation program’s ability to attract, retain and motivate the level of executive talent necessary to achieve the Company’s business goals. The CLO and VP-HR work with the CEO to develop the recommended base salary increases, annual cash incentive compensation levels and long-term equity incentive awards, and provide analysis on the ability of the executive compensation program to attract, retain, and motivate the Company’s executive team and potential executive hires. The CEO, the CLO and VP-HR attend the meetings of the Compensation Committee, but do not participate in the Compensation Committee’s executive sessions.

What are the Company’s executive compensation principles and objectives?

The Compensation Committee believes that the structure of the compensation program for named executive officers should be designed to attract, motivate, and retain key talent to promote the long-term success of the Company, and to balance these objectives with a strong link to stockholder return and other measures of performance that drive total stockholder return.

The Company’s overall executive compensation philosophy is that pay should be competitive with the relevant market for executive talent, be performance-based, vary with the attainment of specific objectives, and be closely aligned with the interests of the Company’s stockholders. The core principles of the Company’s executive compensation program include the following:

The CEO and the Compensation Committee regularly review the executive compensation program and philosophy to assess whether the program promotes the objectives of enabling the Company to attract and retain exceptionally talented executives and to link total compensation to the Company’s ability to meet its annual financial and non-financial goals and, in the longer term, to produce enhanced levels of total stockholder return. Based on such reviews, programmatic changes have been implemented at various times to enhance consistency of the various compensation elements with the program’s philosophy.

Benchmarking: Benchmarking in comparison to a peer group of companies (the “peer group”) is one of several factors considered in the compensation process but is not in and of itself determinative. The relative position of individual named executive officers in comparison to the peer group is based on their respective competencies, experience and performance. While the Company does not establish executive pay based solely on benchmarking data, we believe that our pay levels and practices should be within a range of competitiveness with our peer group and benchmarking provides us with an assessment of reasonableness and competitiveness. However, each individual’s actual compensation is based on numerous factors including the individual’s level of experience in the role and the annual and long-term performance of both the Company and the individual.

The Compensation Committee benchmarks target total direct compensation, which consists of base salary, target annual cash incentive compensation, and the value of long-term equity incentives, to the peer group. The Compensation Committee benchmarks its named executive officer compensation because the Compensation Committee believes this is the best way to determine whether such compensation is competitive with the Company’s labor market for executive talent.

Peer Group: The Compensation Committee (with respect to officer compensation) and Nominating/Corporate Governance Committee (with respect to director compensation) take into account a number of factors for each potential peer group company including, but not limited to, size (revenues, market capitalization and number of

employees), nature of business (business comparators and similar customer base), organizational complexity and business model (span and scope of the organization), competition for executive talent (organizations from which executives may be recruited to and from) and location. While all of the aforementioned factors are taken into account, the Compensation Committee and Nominating/Corporate Governance Committee consider the most important factors to be size, nature of business and competition for executive talent as these provide the most meaningful insight into competitive practices.

In July 2020, the Compensation Committee and the Nominating/Corporate Governance Committee requested that KF review the Company’s existing peer group in light of the Committees’ observation that, although the median yearly revenues of the existing peer group were aligned with the Company, the median market capitalization of the peer group was substantially lower than the Company’s, and there were a number of companies in the peer group that were not branded consumer product businesses. The Committees asked KF to consider modifications to the peer group in light of this observation. In response, KF provided the Committees with a set of considerations for change, including proposed additions and deletions to the peer group.

In July 2020, with input from KF, the Compensation Committee and Nominating/Corporate Governance Committee identified a publicly-traded peer group consisting of the following companies:

Executive Compensation Benchmarking Study: In October 2021 KF completed an executive compensation benchmarking study. KF assessed the Company’s executive compensation program against the peer group both with respect to competitiveness and mix of the elements of compensation. KF compared the following elements of compensation of the Company against the peer group (based on the most recently-filed proxy statement for each peer company at that time, the majority of which reflect 2020 compensation): (1) base salary; (2) target total cash compensation (base salary plus target annual cash incentive compensation); and (3) target total direct compensation (base salary plus target annual cash incentive compensation plus the value of long-term equity incentive compensation). Based on such comparison, KF determined that the Company’s respective elements of target compensation compared against the peer group (as a weighted average of the named executive officers) were as follows:

Although the Compensation Committee understands that the compensation of the named executive officers in the aggregate is less than 100% of the median of the peer group with respect to each element of compensation referred to above, they also recognize that most of the named executive officers are relatively new to their roles over the last couple of years. In October 2021, the Compensation Committee did approve adjustments to compensation for each named executive officer, as further discussed below, to bring their compensation closer to the peer group median.

As a result of the adjustments made by the Compensation Committee, KF determined that the Company’s respective elements of target compensation for 2022 compared against the peer group (as a weighted average of the named executive officers) are as follows:

As the named executive officers’ experience in their positions at the Company continue to expand, the Compensation Committee expects their success and contributions to the Company will expand, and the Committee will continue to focus on recognizing and rewarding the long-term contributions of the management team as well as all employees.

With respect to the mix of target compensation for the named executive officers, KF found that the majority of the executive officers’ total compensation is comprised of variable or “at risk” pay with considerable emphasis on both short and long-term incentives. This highlights the Company’s focus on pay-for-performance, and is consistent with one of the core principles of the Compensation Committee; namely, that a material portion of the executive officers’ total compensation should be dependent on performance.

Base Salary

Base salary is annual fixed cash compensation, and is a standard element of compensation, necessary to attract and retain talent, and provides fixed compensation that an employee can rely upon for his or her ordinary living expenses. Base salary is the principal non-variable element of the Company’s total compensation program.

Base salaries reflect each named executive officer’s responsibilities, the impact of each named executive officer’s position, and the contributions each named executive officer delivers to the Company.

Base salaries are determined by competitive levels in the market, based on the Company’s peer group and the results of executive compensation surveys, for executives with comparable responsibilities and job scope. Base salary increases, if any, are based on individual performance, market conditions and company performance. To gauge market conditions, the Compensation Committee evaluates the peer group and market data compiled by its consultant. Base salaries are set following review of this data upon consideration of the named executive officer’s experience, tenure, performance, and potential.

In October 2021, as described above, the Compensation Committee approved increases in the base salaries for the named executive officers for 2022.

The base salaries of the named executive officers are as follows:

Annual Cash Incentive Compensation

The annual cash incentive plan provides named executive officers with the opportunity to gain financially from the Company’s financial results that they help to generate annually. The annual cash incentive plan provides for a cash payment based on the achievement of annual corporate financial goals.

We believe that it is necessary to provide annual cash incentive compensation, because short-term incentives provide an immediate benefit paid in cash based on the achievement of immediate results, thereby promoting the achievement of short-term goals. A performance-based incentive motivates management to focus on the short-term (one fiscal year) financial goals in specific targeted areas determined at the beginning of each year.

For the named executive officers, the Company provides an annual cash incentive payment based 75% on achievement of a certain pretax income target, and 25% on achievement of a certain operating cash flow target, in each case excluding any items determined by the Compensation Committee to be extraordinary and not considered in the establishment of such targets. Operating cash flow is defined as net cash provided by operating activities. The pretax income and operating cash flow financial performance metrics were chosen because the Compensation Committee determined that they would best measure the Company’s financial performance for the fiscal year and align managements’ financial incentives to those of its stockholders. Management deems pre-tax earnings to be the key factor to increasing shareholder value, which is indicative of its 75% weighting toward the annual cash incentive plan. Management believes that operating cash flow complements pre-tax earnings to ensure the Company’s operating and strategic objectives are being adequately funded as a result of meeting its profit objectives, which is indicative of its 25% weighting towards the annual cash incentive plan. The operating cash flow financial metric also serves as a guideline to meeting management’s target capital structure.

The Compensation Committee uses a sliding scale to determine both the pretax income portion of the annual cash incentive and the operating cash flow portion of the annual cash incentive. The minimum threshold for any payment under both the pretax income element and the operating cash flow element of the annual cash incentive plan for 2021 was 80% of the respective targets, which would result in a payout of 25% of the target payment, performance at target would result in a payout of 100% of the target payment, and the maximum payout was capped at 200% of the target payment if 112.5% or more of the target was achieved. Numbers falling within the ranges above are interpolated on a straight-line basis. These performance ranges were selected based upon the Company’s business judgment while acknowledging the potential variability in results given some of the unique challenges in our business. Each year, the Company determines its performance ranges based upon the best available information and makes an informed decision as to where the threshold, target and maximum performance levels should be set. As explained in more detail below, these performance ranges were established for the 2021 plan year.

Target awards are expressed as a percentage of the named executive officer’s base salary. Cash incentive targets for 2021 were 115% for the CEO, and 70% to 75% for the other named executive officers, depending on the named executive officer’s grade level. The total award to any single named executive officer was capped at 200% of the named executive officer’s targeted percentage of salary.

Determination of Target Levels. The Compensation Committee believes that using pretax income and operating cash flow financial targets as the basis for the executive annual cash incentive plan effectively aligns executive interests with the interests of the Company’s stockholders. An annual cash incentive can be earned if the Company meets its financial goals as measured using pretax income and operating cash flow as adjusted to reflect core operating performance. The annual financial objectives are contained within the Company’s annual financial plan, which is approved by the Board each December prior to the start of the new fiscal year. The Company’s financial-metric based approach established for the annual cash incentive plan applies to the broader management team as well as the named executive officers to ensure that there is consistency with the essence of the “pay-for-performance” structure of the incentive plan. (For non-officers of the Company, Trex Residential Products and Trex Commercial Products employees have separate targets reflecting the annual financial plan for the respective businesses.)

Calculations of Pretax Income Target and Payout for 2021. For the 2021 fiscal year, the Compensation Committee set target pretax income at $279,209,000. The Compensation Committee considered this target challenging given the set of circumstances including the macro-economic and competitive environments known at

the time. In addition, the 2021 pretax income target was 15.8% higher than actual 2020 pretax income (adjusted for extraordinary items).

As stated above, the Compensation Committee specifically agreed to exclude from the actual pretax income calculation any items determined by the Committee to be extraordinary and not considered in the establishment of the pretax income target. For 2021, the Compensation Committee approved an exclusion of a $54,245,000 write-off of goodwill of Trex Commercial Products because this write-off was not anticipated in the 2021 Financial Plan which was approved by the Board in December 2020. For additional information regarding the goodwill write-off of Trex Commercial Products, see “Footnote 5. Goodwill And Other Intangible Assets, Net” in the Company’s Notes to Consolidated Financial Statements for the Year Ended December 31, 2021, which is incorporated herein by reference.

The net effect of the adjustment described in the preceding paragraph was to increase pretax income for 2021 for incentive purposes by $54,245,000 from $275,392,000 to $329,637,000. This equated to 118.06% of target, which resulted in a payment multiple of 200%. This percentage was then multiplied by 75%, which is the percent weight given to the target pretax income portion of the annual cash incentive, to equal 150% for pretax income achievement.

Calculations of Operating Cash Flow Target and Payout for 2021. For the 2021 fiscal year, the Compensation Committee set target operating cash flow at $201,351,000. The Committee felt that this target was reasonable.

As stated above, the Compensation Committee specifically agreed to exclude from the actual operating cash flow calculation any items determined by the Committee to be extraordinary and not considered in the establishment of the operating cash flow target. For 2021, the Committee decreased operating cash flow by $1,217,000 representing payments lower than planned for surface flaking claims. The Committee made this adjustment because it was not anticipated in the 2021 Financial Plan which was approved by the Board in December 2020.

The net effect of the adjustments described in the preceding paragraph was to decrease operating cash flow for 2021 for incentive purposes by $1,217,000 from $258,063,000 to $256,846,000. This equated to 127.56% of target, which resulted in a payment multiple of 200%. This percentage was then multiplied by 25%, which is the percent weight given to the target cash flow portion of the annual cash incentive, to equal 50% for cash flow achievement.

Total Cash Incentive Payout Percentage. As a result of the above calculations, the cash incentive for 2021 to the executive officers was paid at a blended rate of 200% of target, which was determined as follows:

This blended rate was then multiplied by the cash incentive target for each named executive officer, as described above. Actual payouts to each of the named executive officers in February 2022, as a percentage of base salary, were:
