Notice of Annual Meeting of Stockholders

May 2, 2018

To our stockholders:

Notice is hereby given that the 2018 annual meeting of stockholders of Trex Company, Inc. will be held at The George Washington Grand Hotel, 103 East Piccadilly Street, Winchester, Virginia, on Wednesday, May 2, 2018, at 9:00 a.m., local time, for the following purposes:

_➊

to elect two directors of Trex Company, Inc.;

_➋

to approve, on a non-binding advisory basis, the compensation of our named executive officers;

_➌

to approve the Second Certificate of Amendment to the Restated Certificate of Incorporation of Trex Company, Inc. to increase the number of authorized shares of common stock, $0.01 par value per share, from 80,000,000 to 120,000,000;

_➍

to ratify the appointment of Ernst & Young LLP as Trex Company’s independent registered public accounting firm for the 2018 fiscal year; and

_➎

to transact such other business as may properly come before the annual meeting or any adjournment or postponement thereof.

Only stockholders of record at the close of business on March 5, 2018 will be entitled to notice of and to vote at the annual meeting or any adjournment or postponement thereof.

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 2017 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.

By Order of the Board of Directors,

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.

Solicitation Expenses

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.

Voting Procedures; Quorum; Abstentions; Broker Voting

All proxies received pursuant to this solicitation will be voted except as to matters where authority to vote is specifically withheld.

As of March 5, 2018, there were 29,424,763 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, warrant or other right, without regard to whether such right expires before the end of such 60-day period or continues thereafter.

TREX COMPANY, INC.

2018 PROXY STATEMENT

Election of Directors

(Proposal 1)

Nominees for Election as Directors

The current terms of office of the three current classes of directors expire at this annual meeting, at the annual meeting of stockholders in 2019 and at the annual meeting of stockholders in 2020, 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.

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. Frank H. Merlotti, Jr.’s current three year term is scheduled to expire on the date of the 2018 annual meeting. As previously disclosed by the Company, Mr. Merlotti has elected to retire from the Company’s Board, and therefore will not stand for election at the 2018 annual meeting. With Mr. Merlotti’s retirement, Patricia B. Robinson was the only director scheduled for election at the 2018 annual meeting. In order to keep the classes as nearly equal in number as possible, James E. Cline, who was otherwise scheduled for election at the 2019 annual meeting, agreed to be moved to the class of directors whose terms expire at the 2018 annual meeting.

In accordance with the recommendation of the Nominating/Corporate Governance Committee, Ms. Robinson and Mr. Cline 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 2021. These nominees are incumbent directors. Ms. Robinson has served on the Board since her appointment in November 2000. Mr. Cline has served on the Board since his appointment in August 2015.

Approval of Nominees

Approval of the nominees requires the affirmative vote of a plurality of the votes cast at the annual meeting. Abstentions and broker non-votes will have no effect on the election of directors, which is by plurality of the votes cast in person or by proxy. 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.

Information About Nominees and Continuing Directors

Biographical information concerning each of the nominees and each of the directors continuing in office is presented below.

TREX COMPANY, INC.

2018 PROXY STATEMENT

ELECTION OF DIRECTORS (PROPOSAL 1)

James E. Cline has served as President and Chief Executive Officer of the Company since August 17, 2015. He previously served as Senior Vice President and Chief Financial Officer between August 2013 and August 2015, and as Vice President and Chief Financial Officer between March 2008 and July 2013. Mr. Cline served from July 2005 through December 2007 as the President of Harsco GasServ, a subsidiary of Harsco Corporation and a manufacturer of containment and control equipment for the global gas industry. From January 2008 through February 2008, in connection with the purchase of Harsco GasServ by Taylor-Wharton International LLC, which was owned by Windpoint Partners Company, Mr. Cline served as a consultant to the buyers by providing transition management and financial services. From April 1994 through June 2005, Mr. Cline served as the Vice President and Controller of Harsco GasServ. Mr. Cline served in various capacities with Huffy Corporation from June 1976 to February 1994, including as the Director of Finance of its True Temper Hardware subsidiary, a manufacturer of lawn care and construction products. Mr. Cline received a B.S.B.A. degree in accounting from Bowling Green State University.

Mr. Cline was appointed to the Board in August 2015 upon his promotion to President and Chief Executive Officer. Mr. Cline was appointed to the Board in 2015 and renominated this year specifically because the Board felt it was important to have another member of the Board with significant financial expertise in this industry and also because the Board believes it is in the best interest of the Company that the Chief Executive Officer be a member of the Board.

Patricia B. Robinson has been an independent consultant since 1999. From 1977 to 1998, Ms. Robinson served in a variety of positions with Mead Corporation, a forest products company, including President of Mead School and Office Products, Vice President of Corporate Strategy and Planning, President of Gilbert Paper, Plant Manager of a specialty machinery facility and Product Manager for new packaging product introductions.

Ms. Robinson was appointed to the Board in November 2000 as one of the first outside independent directors of the Company and renominated this year due to her professional experience as a President of a consumer products company and her experience with strategic planning and new product introductions. As a consumer products company that continues to innovate with new products, the Board believes this is important experience to have on the Board.

Corporate Governance

Board of Directors and Committees of the Board of Directors

The Board currently consists of eight directors. Upon Mr. Merlotti’s retirement from the Board effective the date of the 2018 annual meeting of stockholders, the Board will consist of seven directors. At this time, the Board has no plans to replace Mr. Merlotti on the Board.

The Board has three standing committees: the Audit Committee, the Compensation Committee and the Nominating/Corporate Governance Committee. During the Company’s 2017 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 2017, 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 the annual meetings of the Company’s stockholders. All of the directors attended the annual meeting of stockholders in 2017.

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 and Risk Oversight

Our Board is currently led by a non-executive Chairman, Mr. Kaplan, who retired as the Company’s President and Chief Executive Office on August 17, 2015. Our Board determined that retaining Mr. Kaplan as Chairman, despite him retiring as chief executive officer, was in the best interests of the Company because it allows the Company to benefit from Mr. Kaplan’s significant experience and accumulated expertise about the Company’s industry and the Company’s internal policies, practices and procedures to effectively and expertly guide the Board. 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. Kaplan serve as chairman will allow Mr. Cline, the Company’s President and Chief Executive Officer effective August 17, 2015 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.

Mr. Merlotti served as the Company’s Lead Independent Director until May 3, 2017, at which time, Ms. Robinson was appointed as the Lead Independent Director for term ending on August 18, 2018, at which time Mr. Kaplan will be considered “independent” under New York Stock Exchange Rules. Mr. Merlotti and Ms. Robinson are both experienced former chief executive officers. (For additional information regarding Mr. Merlotti’s and Ms. Robinson’s professional experience, please see “Proposal 1 — Election of Directors”.) Pursuant to the Company’s Corporate Governance Principles, the responsibilities of the Lead Independent Director may include: presiding at executive sessions of the independent directors; presiding at Board meetings in the absence of the 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.

Our Board also has three standing committees:

∎ Audit Committee, chaired by Mr. Gratz;

∎ Compensation Committee, chaired by Mr. Posey; and

∎ Nominating/ Corporate Governance Committee, chaired by Mr. Merlotti until May 3, 2017 and by Mr. Golden after such date.

TREX COMPANY, INC.

2018 PROXY STATEMENT

CORPORATE GOVERNANCE

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.

The Board of Directors’ Role in Risk Oversight. 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 Chief Executive Officer 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.

The Board believes that its current leadership structure best facilitates its oversight of risk by combining independent leadership, through the Lead Independent Director, independent board committees, and majority independent board composition, with an experienced Chairman and an experienced Chief Executive Officer who each have intimate knowledge of our business, history, and the complex challenges we face. The Chief Executive Officer’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, 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 Lead Independent Director, independent board committees, independent board members, the Chairman, and the Chief Executive Officer, 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 Chief Executive Officer 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 General Counsel updates 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 Chief Financial Officer, independent auditor, internal auditor, 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 auditor 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 for all employees 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 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 such vote.

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, and our corporate governance profile and ratings. The Committee also is actively engaged in overseeing risks associated with succession planning for the Board and management.

Director Independence. The Board has affirmatively determined that all of the current directors, other than Mr. Kaplan, who is the Company’s Chairman and former President and Chief Executive Officer, and Mr. Cline, 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, or “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 million 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:

∎ The director is, or has been within the last three years, an employee of the Company, or an immediate family member is, or has been within the last three years, an executive officer, of the Company.

∎ The director has received, or has an immediate family member who has received, during any twelve-month period within the last three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service).

∎ The director is a current partner or employee of a firm that is the Company’s internal or external auditor; the director has an immediate family member who is a current partner of such a firm; the director has an immediate family member who is a current employee of such a firm and personally works on the Company’s audit; or the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the Company’s audit within that time.

∎ The director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company’s present executive officers at the same time serves or served on that company’s compensation committee.

∎ The director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1 million, or 2% of such other company’s consolidated gross revenues.

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 held five executive sessions in 2017. Mr. Kaplan, as Chairman, acted as presiding director for each such executive session of non-management directors. In 2017, the Company’s independent directors held one executive session, at which Ms. Robinson presided.

Audit Committee. The Audit Committee of the Board is a standing committee composed of four non-employee directors who meet the independence and expertise requirements of the NYSE listing standards. Pursuant to SEC rules, the Board has determined that Jay M. Gratz and Gerald Volas are “audit committee financial experts,” as

Compensation Committee Interlocks and Insider Participation

No member of the Compensation Committee was an officer or employee of the Company or any subsidiary of the Company during 2017. There are no interlock relationships as defined in the applicable SEC rules.

Director Nominations Policy

The Board has, by resolution, adopted a director 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, professional experience, education and skill, race, gender 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 Trex 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

2018 PROXY STATEMENT

CORPORATE GOVERNANCE

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.

Communications with the Board of Directors; Reporting Questionable Accounting, Internal Accounting Controls and Auditing Matters

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. To maintain the caller’s anonymity, calls are passed through proprietary filters to “mask” the caller’s voice and the originating phone number is removed from the associated audio file. A caller wishing to be identified may indicate his or her name in the message. All calls are forwarded to both the Company Secretary and Chief Financial Officer. 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, and to maintain the caller’s anonymity, calls are passed through proprietary filters to “mask” the caller’s voice and the originating phone number is removed from the associated audio file. 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.

Section 16(a) Beneficial Ownership Reporting Compliance

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 2017 or written representations that no other reports were required, the Company believes that the foregoing reporting persons complied with all filing requirements for fiscal 2017.

Availability of Code of Conduct and Ethics, Bylaws, Corporate
Governance Principles, and Committee Charters

Amended and Restated 1999 Incentive Plan for Outside Directors, or “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 Trex Company, Inc. 2014 Stock Incentive Plan, or “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 Hay Group (“KFHG”), to advise the Nominating/Corporate Governance Committee on matters related to director compensation.

The Company’s director compensation program was reviewed by KFHG in 2015 relative to the Company’s peer group. The Company’s peer group is reviewed by KFHG prior to each compensation review, and the peer group utilized in such study was as follows:


AAON, Inc.		Landec Corp.
American Woodmark Corp.		L.B. Foster Company
Apogee Enterprises, Inc.		Patrick Industries, Inc.
Deltic Timber Corp.		PGT, Inc.
Gibraltar Industries, Inc.		Quanex Building Products Corporation
Insteel Industries, Inc.		Simpson Manufacturing, Inc.
Kadant Inc.		Twin Disc, Inc.

The KFHG review indicated that the non-employee directors’ total annual compensation (consisting of cash and equity-based compensation) was approximately at the 25^th percentile of the Company’s peer group. Based upon the Nominating/Corporate Governance Committee’s desire to have director compensation approximate the median of its peer group, KFHG provided pay level and pay structure alternatives for the Committee’s consideration. Based on KFHG’s analysis, the Committee recommended and the Board approved certain modifications to the Outside Director Plan in October 2015. The elements of the non-employee director compensation package under the Outside Director Plan, as modified, 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 $50,000, 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 $70,000.

∎ Any non-employee director who serves as Chairman of the Board will receive an additional $60,000 annually, and any director who serves as Lead Independent Director will receive an additional $15,000 annually.

∎ The chairman of the Audit Committee receives an annual committee fee of $12,500, the chairman of the Compensation Committee receives an annual committee fee of $9,000, and the chairman of the Nominating/Corporate Governance Committee receives an annual committee fee of $7,500.

∎ Each member of the Audit Committee (other than the chairman) receives an annual committee fee of $8,500, each member of the Compensation Committee (other than the chairman) receives an annual committee fee of $6,500 and each member of the Nominating/Corporate Governance Committee (other than the chairman) receives an annual committee fee of $5,000.

∎ The $50,000 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

TREX COMPANY, INC.

2018 PROXY STATEMENT

DIRECTOR COMPENSATION

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 annual cash compensation and equity compensation at the median of the Company’s peer group. The Outside Director Plan is designed to deliver compensation approximately 50% in cash and 50% in equity (assuming a director does not elect to receive additional equity in lieu of cash, as discussed 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. Notwithstanding the foregoing, 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.)

Compensation Discussion and Analysis

Introduction

This section describes the Company’s compensation program for its Chief Executive Officer (“CEO”), its Chief Financial Officer (“CFO”), and its four other most highly compensated executive officers for fiscal year 2017, all of whom are referred to collectively as the “named executive officers”. For fiscal 2017, the Company’s named executive officers were:

∎

James E. Cline, President and Chief Executive Officer;

∎

William R. Gupp, Senior Vice President, General Counsel and Secretary;

∎

Bryan H. Fairbanks, Vice President and Chief Financial Officer;

∎

Christopher P. Gerhard, Vice President, Sales;

∎

Jay T. Scripter, Vice President, Operations; and

∎

Adam D. Zambanini, Vice President, Marketing.

This Compensation Discussion and Analysis focuses on the material elements of our executive compensation program in effect for the 2017 fiscal year. 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 Compensation Committee establishes 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.

2017 Say-on-Pay Results and Considerations

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 2017 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, 2017 received 22,600,030 votes in favor, or 93.0% 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.

Compensation Philosophy and Objectives

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 and the other named executive officers, as well as Vice Presidents who report directly to the CEO. Additionally, the Compensation Committee administers the Company’s employee

TREX COMPANY, INC.

2018 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS

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 Hay Group (“KFHG”) in 2017 as the committee’s independent compensation consultant to advise the Compensation Committee on matters related to CEO and other named executive officer compensation. The Compensation Committee assessed KFHG’s work as required under rules of the SEC and concluded that it did not raise any conflicts of interest and that KFHG 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 KFHG for services performed during 2017 relating to executive compensation were $10,720. During 2017, KFHG also was retained by Management of the Company to provide succession planning and executive leadership consulting services. Management interviewed a number of consultants, but concluded that KFHG 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 for such services performed during 2017 was $544,498. The decision to retain KFHG to provide these additional services was approved by the Nominating/Corporate Governance Committee and the Board.

The Role of Executives. The Company’s CEO, its Senior Vice President, General Counsel and Secretary, or “GC,” and its Vice President, Human Resources, or “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 and the consultant 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 GC 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 GC 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.

TREX COMPANY, INC.

2018 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS

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:

∎

Pay competitively: The Compensation Committee believes in positioning executive compensation at competitive levels necessary to attract and retain exceptional leadership talent. An individual’s performance and importance to the Company can result in that individual’s total compensation being higher or lower than the Company’s target market position. The Compensation Committee regularly utilizes the assistance of a compensation consultant to provide information on market practices, programs, and compensation levels.

∎

Pay-for-performance: The Compensation Committee structures executive compensation programs to balance annual and long-term corporate objectives, including specific measures which focus on financial performance, with the goal of fostering stockholder value creation in the short- and long-term.

∎

Create an ownership culture: The Compensation Committee believes that using equity compensation to instill an ownership culture effectively aligns the interests of management and the stockholders. To promote this alignment, the Compensation Committee granted equity-based compensation in 2017, which was comprised of time-based restricted stock units, performance-based restricted stock units and stock appreciation rights, to provide incentives for named executive officers to enhance stockholder value.

∎

Utilize a total compensation perspective: The Compensation Committee considers all of the compensation components — base salary, annual cash incentive compensation, long-term equity incentive compensation, and benefits and perquisites — in total.

∎

Improved financial performance: The Company aggressively pursues strategies intended to improve its financial and operational performance by expanding its product offerings, enhancing its sales channels, improving production performance, including quality, efficiency and capacity, and lowering costs. The Compensation Committee believes in utilizing a compensation program that appropriately rewards executives for the achievement of these objectives.

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.

How Do We Determine Executive Pay?

Benchmarking: Benchmarking in comparison to the peer group (see below) 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. To that end, the Company generally views the median of the market as a reference point against which to evaluate the competitiveness of its target total direct compensation. 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 a peer group of companies (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.

TREX COMPANY, INC.

2018 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS

Peer Group: In July 2016, KFHG reviewed the Company’s existing peer group and provided the Compensation Committee with a set of considerations for change, including proposed additions and deletions to the peer group. Based on KFHG’s analysis, the Compensation Committee refined its peer group taking into account a number of factors for each potential peer 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, KFHG considers the most important to be size and competition for executive talent as these provide the most meaningful insight into competitive practices.

In July 2016, with input from KFHG, the Compensation Committee identified a publicly-traded peer group consisting of the following fifteen companies:


AAON, Inc.		Kadant, Inc.
American Woodmark Corp.		L.B. Foster Company
Apogee Enterprises, Inc.		Patrick Industries, Inc.
Continental Building Products, Inc.		PGT, Inc.
Deltic Timber Corp.		Quanex Building Products Corporation
Gibraltar Industries, Inc.		Simpson Manufacturing, Inc.
Headwaters, Inc.		Twin Disc, Inc.
Insteel Industries, Inc.

In October 2016, KFHG completed an executive compensation benchmarking study. KFHG assessed the Company’s executive compensation program against the peer group both with respect to competitiveness and mix of the elements of compensation. KFHG compared the following elements of compensation of the Company against the peer group for 2015 (the last reported compensation for the peer group): (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, KFHG 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:


				Weighted Average % of Median (all NEOs)
Base Salary				99.79%
Target Total Cash Compensation				89.48%
Target Total Direct Compensation				90.19%

With respect to the mix of target compensation for the named executive officers, KFHG 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.

Elements of Executive Compensation

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.

TREX COMPANY, INC.

2018 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS

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 December 2016, the Compensation Committee approved a 3% increase in the 2017 base salaries for the named executive officers, based on an internal analysis of prevailing market and industry conditions, except that with respect to Mr. Cline, the Committee approved a 6% increase, and for Mr. Gerhard and Mr. Zambanini, the Committee approved a 5% increase, all in recognition of their significant contributions to the Company and below median salary compared to our peer companies.

In December 2017, the Compensation Committee approved increases in the 2018 base salaries for the named executive officers. The average increase for the named executive officers was 3.47%.

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 free 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. Free cash flow is defined as net cash provided by operating activities less net cash used for investing activities. The pretax income and free 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 free 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 free-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 free cash flow portion of the annual cash incentive. The minimum threshold for any payment under both the pretax income element and the free cash flow element of the annual cash incentive plan

for 2017 was 80% of the respective targets, which would result in a payout of 50% of the target payment, and the maximum payout was capped at 200% of the target payment if 120% 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 2017 plan year.

Target awards are expressed as a percentage of the named executive officer’s base salary. Cash incentive targets for 2016 were 100% for the CEO, and 60% to 70% 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 free 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 free 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.

Calculations of Pretax Income Target and Payout for 2017. For the 2017 fiscal year, the Compensation Committee set target pretax income at $124,888,000. 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 2017 pretax income target was 10.8% higher than actual 2016 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 Compensation Committee to be extraordinary and not considered in the establishment of the pretax income target. On July 31, 2017, the Company, through its newly formed, wholly-owned subsidiary Trex Commercial Products, Inc. (“TCP”) acquired substantially all of the assets of Staging Concepts Acquisition, LLC (“SC Company”), which operated under the tradenames SC Railing Company and Staging Concepts. For 2017, the Committee agreed to exclude all items related to the acquisition of SC Company. This included a $3,404,000 pretax loss by TCP, $218,000 in equity awards by the Company to the senior executives of SC Company, and $266,000 in acquisition costs. The Compensation Committee excluded all items related to the acquisition because they determined that it was an extraordinary event not anticipated in the 2017 Financial Plan which was approved by the Board in December 2016.

The net effect of the adjustment described in the preceding paragraph was to increase pretax income for 2017 for incentive purposes by $3,888,000 from $141,919,000 to $145,807,000. This equated to 116.75% of target, which resulted in a payment multiple of 183.75%. 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 137.81% for pretax income achievement.

Calculations of Free Cash Flow Target and Payout for 2017. For the 2017 fiscal year, the Compensation Committee set target free cash flow at $64,128,000. Although this was lower than actual 2016 free cash flow of $70,810,000 (adjusted for extraordinary items), the Committee felt that this target was reasonable given planned working capital changes and capital investments.

As stated above, the Compensation Committee specifically agreed to exclude from the actual free cash flow calculation any items determined by the Compensation Committee to be extraordinary and not considered in the establishment of the free cash flow target. For 2017, the Committee agreed to exclude all items related to the acquisition of SC Company. This included $72,070,000 in purchase price for SC Company and other acquisition costs, $4,542,000 in an intra-company loan to TCP and $14,000 in negative cash generation by TCP. The

COMPENSATION DISCUSSION AND ANALYSIS

Compensation Committee excluded all items related to the acquisition because they determined that it was an extraordinary event not anticipated in the 2017 Financial Plan which was approved by the Board in December 2016. The Compensation Committee also excluded $244,000, which represented payments under the warranty reserve for decking material manufactured at the Company’s Nevada plant prior to 2007 that were $244,000 more than planned for. The Compensation Committee excluded this item because they concluded that it would not be appropriate to penalize management because it related to product sold prior to the current senior management team assuming responsibility in early 2008.

The net effect of the adjustments described in the preceding paragraph was to increase free cash flow for 2017 for incentive purposes by $76,870,000 from $15,076,000 to $91,946,000. This equated to 143.38% 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 2017 to the executive officers was paid at a blended rate of 187.81% of target, which was determined as follows:


Pretax Income achievement				183.75% x .75 = 137.81%
Free cash flow achievement				200.00% x .25 = 50.00%
Total				187.81%

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 2018, as a percentage of base salary, were:


Executive Officer	2017 Base Salary	Target Annual Cash Incentive (as a % of Base Salary)	Target Annual Cash Incentive	Annual Cash Incentive Payout Percentage	2017 Annual Cash Incentive

Adam D. Zambanini	$262,500	60%	$157,500	187.81%	$295,805

Plan Structure and Target Levels for 2018 Annual Cash Incentive Plan. In December 2017, the Compensation Committee established the pretax income and free cash flow targets for 2018, consistent with the Company’s internal Financial Plan approved by the Board in December 2017, with pretax income again being weighted at 75% and free cash flow weighted at 25%. The program mechanics for the 2018 annual cash incentive plan will be the same as they were for the 2017 annual cash incentive plan, which is discussed in detail above.

Long-Term Equity Incentive Compensation

We believe that long-term equity incentive compensation provides appropriate motivational tools to achieve certain long-term company goals. The long-term equity incentive compensation plan is designed to align named executive officers’ interests with those of stockholders, motivate the named executive officer team to achieve key financial goals and reward superior performance. The design of the program helps to reduce turnover and to retain the knowledge and skills of the Company’s valued employees. In structuring the amount of long-term equity incentive compensation awards, the Compensation Committee seeks to balance such awards and the interests of the Company’s stockholders under a policy that moderates the dilutive effects of annual equity-based awards against the need to provide attractive and competitive incentive compensation.

The Compensation Committee regularly makes its annual long-term equity incentive grants to named executive officers at its February meeting, with the grant date being the date of the Compensation Committee meeting at which such equity grants are approved. The Company does not time the grant of equity awards in coordination with the release of material non-public information.

TREX COMPANY, INC.

2018 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS

Under the long-term equity incentive compensation plan of the Company in 2017, grants consisted of 35% time-based restricted stock units, 50% performance-based restricted stock units, and 15% stock appreciation rights. The target levels for long-term equity incentive compensation grants for the named executive officers were 200% of base salary for the CEO and 115% to 135% of base salary for the other named executive officers, depending on the named executive officer’s grade level.

The Compensation Committee retains discretion to adjust the target percentage award based upon each named executive officer’s current performance and anticipated future contribution to the Company’s results, as well as upon the amount and terms of equity-based awards previously granted to the named executive officer by the Company. The Compensation Committee did not make any discretionary adjustments to a named executive officer’s target percentage award, and has not done so for any of the named executive officers in any of the years reflected in the Summary Compensation Table.

Elements of Long-Term Equity Incentive Compensation:

Time-Based Restricted Stock Units. Time-based restricted stock units are similar to time-based restricted shares, with the principal difference being that with restricted stock units, the shares are not actually issued until vesting. The restricted stock units have a three-year vesting period, vesting one-third each year. The number of restricted stock units issued is based on the approved target dollar amount of the award, divided by the fair market value of the Company’s common stock on the date of the grant. Upon vesting, each restricted stock unit will equal the right to receive one share of Company stock.

Time-based restricted stock units facilitate retention by providing value if the named executive officer remains with the Company over the vesting period. In addition, time-based restricted stock units provide alignment with stockholders through stock ownership, and the potential for future growth.

Performance-Based Restricted Stock Units. Performance-based restricted stock units are similar to their time-based counterparts, but the number of units that will vest each year, if any, is based on Company financial performance. Upon vesting, each restricted stock unit will equal the right to receive one share of Company stock. The performance-based restricted stock units have a three-year vesting period, vesting one-third each year based on performance against target earnings before interest, taxes, depreciation and amortization, or “EBITDA,” for 1 year, cumulative 2 years and cumulative 3 years, respectively, in each case excluding any items determined by the Compensation Committee to be extraordinary and not considered in the establishment of such targets.

∎ For the first vesting, the target performance will be planned EBITDA for the first year.

∎ For the second vesting, the target performance will be cumulative planned EBITDA for the first two years, with the target EBITDA for the second year equaling the first year’s target EBITDA plus a pre-determined growth rate.

∎ For the third vesting, the target performance will be cumulative planned EBITDA for the three years, with the target EBITDA for the third year equaling the second year’s target EBITDA plus a pre-determined growth rate.

The target number of performance-based restricted stock units issued is based on the approved target dollar amount of such units to be awarded, divided by the fair market value of the Company’s common stock on the date of the grant. With respect to each vesting, the number of units that will vest will be between 0% and 200% of the target number of units. The Compensation Committee uses a sliding scale to determine the percentage of the target units that will vest each year. The minimum threshold for any vesting will be 80% of the EBITDA target, which will result in a payout of 50% of the target vesting, and the maximum payout will be capped at 200% of the target vesting if 120% or more of the target is achieved. Numbers falling within the ranges above are interpolated on a straight line basis.

In addition to facilitating retention, performance-based restricted stock units also more closely align the long-term equity incentive compensation plan with the Company’s pay for performance philosophy. The number of units that will vest each year is contingent upon performance against pre-determined EBITDA targets. If the Company achieves less than 80% of the target for any year, no units will vest. This vesting condition encourages named executive officers to work with a long-term view of the Company’s performance and reinforces their long-term affiliation with the Company.

COMPENSATION DISCUSSION AND ANALYSIS

Stock Appreciation Rights. Stock Appreciation Rights, or “SARs,” are grants which, upon exercise, give the holder the right to receive the net appreciation in market value of a specified number of shares of our common stock over the grant price. Upon exercise, the net appreciation over the base price is settled in an equivalent number of common shares valued on the exercise date. SARs are similar to stock options but are less dilutive because only a net number of shares are issued. With respect to SARs, the grant price is the closing market price of the Company’s common stock on the NYSE on the grant date. The SARs have a three-year vesting period, vesting one-third each year. The number of SARs issued is based on the approved target dollar amount of SARs to be awarded, divided by the value of one SAR, which is equal to the Black-Scholes value of an equivalent stock option. SARs have a term of ten years (provided that the term is extended for one year if the holder dies during the tenth year of the SAR.

SARs motivate executive efforts to achieve results that produce long-term increases (since executives have up to 10 years to exercise their SARs) in common stock market price. The three-year SAR vesting period encourages named executive officers to work with a long-term view of the Company’s performance and reinforces their long-term affiliation with the Company. Named executive officers receive value in the SAR grants only when the share price increases above the grant price, which strengthens their alignment with stockholder interests.

The award agreements for the time-based restricted stock units, performance-based restricted stock units and SARs provide that if a participant’s employment with the Company is terminated due to death, permanent and total disability, retirement, by the Company without “cause,” or by the participant with “good reason” (with “cause” and “good reason” being defined in the award agreements), any unvested awards held by a participant at termination will vest (with performance-based restricted stock units vesting at target levels). The award agreements and the change in control agreements further provide that in the event of a change in control of the Company, any unvested awards held by the participant at the time of the change in control will vest (with performance-based restricted stock units vesting at target levels). For a discussion of the change in control agreements, see the Severance/Change in Control Agreements discussion following this Compensation Discussion and Analysis.

2017 Long-Term Equity Incentive Compensation Awards. The target levels for the 2017 grants made in February 2017 were 200% of base salary for the CEO and 115% to 135% of base salary for the other named executive officers, depending on the named executive officer’s grade level, and consisted of 35% time-based restricted stock units, 50% performance-based restricted stock units, and 15% stock appreciation rights. The award of any long-term incentive in 2017 was conditioned on the attainment in 2016 of positive pretax earnings, excluding certain items determined by the Compensation Committee to be extraordinary and not considered in the establishment of such target. The Company earned positive pretax earnings in 2016, so the awards were made in February 2017 at target levels.

2018 Long-Term Equity Incentive Compensation Awards. The target levels for the 2018 grants made in February 2018 were the same as in 2017: 200% of base salary for the CEO and 115% to 135% of base salary for the other named executive officers, depending on the named executive officer’s grade level, and consisted of 35% time-based restricted stock units, 50% performance-based restricted stock units, and 15% stock appreciation rights. The award of any long term incentive in 2018 was conditioned on the attainment in 2017 of positive pretax earnings, excluding certain items determined by the Compensation Committee to be extraordinary and not considered in the establishment of such target. The Company earned positive pretax earnings in 2017, so awards were made in February 2018 at target levels.

Vesting of Previously Granted Performance-Based Restricted Shares and Restricted Stock Units Based upon 2017 Performance. In February 2018, (a) one-third of performance-based restricted shares granted in 2015 vested based on actual EBITDA performance in 2015, 2016 and 2017 (cumulative) against the EBITDA target, (b) one-third of performance-based restricted stock units granted in 2016 vested based on actual EBITDA performance in 2016 and 2017 (cumulative) against the EBITDA target, and (c) one-third of performance-based restricted stock units granted in 2017 vested based on actual EBITDA performance in 2017 against the EBITDA target. The following is a summary with respect to the vesting of performance-based restricted shares and restricted stock units granted in each of 2015, 2016 and 2017.

Performance-Based Restricted Shares Granted in 2015

As stated above, with respect to the performance-based restricted shares granted in 2015, one-third of such shares vested in February 2018 based upon actual EBITDA performance in 2015, 2016 and 2017 cumulatively against target. The target was $291,340,000 which was based upon target EBITDA of $88,018,000 in 2015 (established in December 2014), with 10% year over year growth for 2016 ($96,820,000) and 2017 ($106,502,000).

As reported in the Company’s 2016 Proxy Statement, EBITDA for 2015 adjusted for extraordinary items was $98,855,000. As reported in the Company’s 2017 Proxy Statement, EBITDA for 2016 adjusted for extraordinary items was $127,971,000.

With respect to EBITDA for 2017, the Compensation Committee agreed to exclude from the actual EBITDA calculation for 2017 certain items that it determined to be extraordinary and not considered in the establishment of the EBITDA target for 2017. For 2017, the Committee agreed to exclude all items related to the acquisition of SC Company. This included $1,272,000 negative EBITDA for TCP, $266,000 in acquisition costs, and $218,000 in equity awards by the Company to the senior executives of SC Company. The Compensation Committee excluded all items related to the acquisition because they determined that it was an extraordinary event not anticipated in the establishment of the EBITDA target for 2015-2017 which was approved by the Board in December 2014.

The net effect of the adjustment described above was to increase EBITDA for 2017 for incentive purposes by $1,756,000 from $159,110,000 to $160,866,000. Adding this number to actual adjusted EBITDA for 2015 of $98,855,000, and actual adjusted EBITDA for 2016 of $127,971,000, this resulted in a cumulative adjusted EBITDA for 2015, 2016 and 2017 of $387,692,000, which equated to 133.07% of the target EBITDA of $291,340,000, which resulted in a payment multiple of 200.00%.

Performance-Based Restricted Shares Granted in 2016

As stated above, with respect to the performance-based restricted stock units granted in 2016, one-third of such units vested in February 2018 based upon actual EBITDA performance in 2016 and 2017 cumulatively against target. The target was $232,046,000, which was based upon target EBITDA of $110,498,000 in 2016 (established in December 2015), with 10% year over year growth for 2017 ($121,548,000).

COMPENSATION DISCUSSION AND ANALYSIS

As stated above, adjusted EBITDA for 2017 was $160,866,000. Adding this number to actual adjusted EBITDA for 2016 of $127,971,000 resulted in cumulative adjusted EBITDA for 2016 and 2017 of $288,837,000, which equated to 124.47% of target EBITDA of $232,046,000, which resulted in a payment multiple of 200.00%.

Performance-Based Restricted Stock Units Granted in 2017

As stated above, with respect to the performance-based restricted stock units granted in 2017, one-third of such units vested in February 2018 based upon actual EBITDA performance in 2017 against target. The target was $139,865,000 established in December 2016). As stated above, adjusted EBITDA for 2017 was $160,866,000, which equated to 115.02% of target EBITDA, which resulted in a payment multiple of 175.08%.

Pay Ratio Disclosure

In August 2015, pursuant to a mandate of the Dodd-Frank Wall Street Reform and Consumer Protection Act, the Securities and Exchange Commission adopted a rule requiring annual disclosure of the ratio of the annual total compensation of the median employee (“Median Employee”) to the total annual compensation of the principle executive officer (“PEO”). Such disclosure is now required beginning with proxy statements filed in 2018. The purpose of the new required disclosure is to provide a measure of the equitability of pay within an organization.

The Company’s PEO is Mr. Cline. We identified the Median Employee by examining the 2017 total compensation, as reported on W-2 Statements, for all employees, excluding our PEO, who were employed by us on December 31, 2017. We included all full-time, part-time, seasonal or temporary employees. We did not include temporary workers employed by a third party (i.e., “leased workers”). For any full-time or part-time employees hired during 2017 or for any employee on an unpaid leave of absence during the year, we annualized their compensation. We did not do this for seasonal or temporary or employees. Once we determined the identity of the Median Employee, we calculated such employee’s 2017 compensation using the same methodology as that used in the Summary Compensation Table for Mr. Cline.

On July 31, 2017, the Company, through its newly formed wholly-owned subsidiary Trex Commercial Products, Inc. (“TCP”), acquired substantially all of the assets of Staging Concepts Acquisition, LLC, which operated under the tradenames SC Railing Company and Staging Concepts. As of December 31, 2017, TCP had 186 employees, who we did not include in our determination of the Median Employee.

In determining our Median Employee, we have excluded our foreign employees, who comprise less than 5% of our total employees. As of December 31, 2017, we had 929 U.S. employees and 8 non-U.S. employees. The non-U.S. employees include 6 Canadian employees, 1 German employee and 1 United Kingdom employee.

Mr. Cline (“PEO”) Total Annual Compensation				$3,105,533
Ratio of PEO to Median Employee Total Annual Compensation				49.3:1.0

Retention Agreements

As previously disclosed in prior proxy statements and filed with the Company’s previous Annual Reports on Form 10-K, on July 24, 2012, the Company entered into retention agreements with Mr. Kaplan, Mr. Cline, Mr. F. Timothy Reese (former Vice President, Operations) and Mr. Gupp pursuant to which the Company granted restricted shares and agreed to pay cash retention payment awards, with the restricted stock vesting and the cash payment being made only if certain retention conditions were met.

Mr. Kaplan retired as President and Chief Executive Officer on August 17, 2015, and therefore satisfied the terms of his Retention Agreement. Accordingly, on such date, Mr. Kaplan received a cash payment of $1,055,800 and 74,484 restricted shares vested.

Mr. Cline remained with the Company through January 1, 2017, and therefore satisfied the terms of his Retention Agreement. Accordingly, on such date, Mr. Cline received a cash payment of $491,470 and 34,672 restricted shares vested.

Mr. Reese resigned from the Company effective June 30, 2015, and therefore did not satisfy the terms of his Retention Agreement. Accordingly, Mr. Reese forfeited any right to payment of the cash retention amount or vesting of any restricted shares.

Mr. Gupp successfully resolved the legal matters required by his Retention Agreement, and remained employed through August 16, 2015, and therefore satisfied the terms of his Retention Agreement. Accordingly, on such date, Mr. Gupp received a cash payment of $437,920 and 30,894 restricted shares vested.

Perquisites

The Company provides a limited number of perquisites to its named executive officers. The perquisites offered to the named executive officers in 2017 include 401K contributions, a monthly company car allowance, and life insurance premiums.

The Compensation Committee believes that the benefits the Company and the named executive officers derive from perquisites more than offset their costs to the Company. The personal benefits are considered to constitute a part of the Company’s overall program and are presented in this light as part of the total compensation package approved by the Compensation Committee at the time of an executive officer’s hiring or promotion, as part of the Compensation Committee’s review of each named executive officer’s annual total compensation, and in compensation discussions with named executive officers.

The Compensation Committee oversees the design, implementation and administration of all the Company benefit programs, including perquisites. The Compensation Committee, with the assistance of its consultant, periodically reviews the cost and prevalence of these programs to determine whether they are in line with competitive practices and are warranted based upon business needs and the contributions of the named executive officers.

Additional information about these perquisites can be found in the All Other Compensation Table below.

Additional Information on our Program

Stock Ownership Guidelines

To align our officers’ and directors’ interests with those of our stockholders, the Board in December 2013 instituted Stock Ownership Guidelines.

Under these Guidelines, each executive officer 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 a stated multiple of the executive officer’s base salary. The stated multiple for the Chief Executive Officer is 3, for a Senior Vice President is 1.5 and for a Vice President is 1. 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), unvested time-based restricted shares or restricted stock units, and unvested performance-based restricted shares or restricted stock units at target levels.

Executive officers have 5 years from the adoption of the Guidelines or 5 years from becoming an executive officer, whichever occurs later, to comply with the ownership requirements. Notwithstanding the foregoing, each named executive officer meets the current minimum requirements.

Anti-Hedging and Anti-Pledging Policy

The Board adopted in October 2013, on a voluntary basis and in advance of final Dodd-Frank Act hedging/pledging rules, a policy that prohibits our executive officers 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.

Clawback Policy

The Board adopted in October 2013, on a voluntary basis and in advance of final Dodd-Frank Act “clawback” (or compensation recovery) rules, a “clawback” policy with respect to incentive-based compensation. The policy provides that in the event of a restatement of the Company’s financial results due to any fraudulent actions or executive misconduct, the Compensation Committee is entitled to recover from executive officers any incentive-based compensation that would not otherwise have been awarded to such persons under the as-restated financial statements during the three years preceding the date of the restatement.

Does the Company have Severance or Change-in-Control Agreements with its named executive officers?

The named executive officers have severance agreements, which provide for certain benefits upon an involuntary termination. These agreements promote retention of high-performing individuals and also assist in recruiting and retaining key employees by providing competitive arrangements. In addition, the Company has entered into change in control agreements with the named executive officers to provide certain cash payments to the officers upon a termination following a change in control, which is in the form of a “double trigger.” In addition, such agreements provide for an acceleration of equity grants upon a change in control. Change in control agreements are designed to protect executives in the event of a change in control, and provide security for executives against sudden or arbitrary termination in connection with a change in control. The provisions of each agreement were determined by analysis of peer group and market trends and practices and are set at competitive levels with industry practice.

For a discussion of these arrangements, including the estimated quantification of these amounts, see the Severance/Change in Control Agreements discussion following this Compensation Discussion and Analysis.

How do our decisions regarding each element affect decisions regarding the other elements?

The Compensation Committee considers total cash and equity compensation when setting the compensation of executive officers. In doing so, the Compensation Committee considers the retention value of the long-term equity

TREX COMPANY, INC.

2018 PROXY STATEMENT

COMPENSATION DISCUSSION AND ANALYSIS

currently held by the executive. Based on this review, the Compensation Committee may decide to adjust one or more elements of an executive’s total compensation. The Compensation Committee aims to provide competitive total direct compensation and assesses an executive’s total compensation package when looking at the executive’s competitive standing relative to the market. Additionally, the Compensation Committee seeks to provide a competitive compensation mix, with discretion depending on factors deemed relevant to the Compensation Committee, such as individual performance, internal equity, and historical pay practices. Certain compensation decisions may specifically affect other elements of compensation. For example, because potential annual cash incentive and long-term equity incentive payouts are based on the executive’s base salary, increases in base salary also increase the amount of such payouts.

What are the tax and accounting considerations that factor into decisions regarding executive compensation?

We consider tax and accounting implications in determining our compensation programs.

Policy on Deductibility of Named Executive Officer Compensation. In evaluating compensation program alternatives, the Compensation Committee considers the potential impact on the Company of Section 162(m) of the Internal Revenue Code. Section 162(m) eliminates the deductibility of compensation over $1 million paid to the CEO and three other most highly-compensated named executive officers (other than the CEO), excluding “performance-based compensation.” Compensation programs generally will qualify as performance-based if compensation is based on pre-established objective performance targets, the programs’ material features have been approved by stockholders, and there is no discretion to increase payments after the performance targets have been established for the performance period.

It should be noted that the Tax Cuts and Jobs Act signed by President Donald Trump on December 22, 2017 eliminates the exception for “performance-based compensation” beginning with the 2018 tax year.

To the extent a named executive officer would otherwise earn over $1 million in compensation in any calendar year, the Compensation Committee generally endeavors to maximize deductibility of compensation under Section 162(m) of the Internal Revenue Code to the extent practicable while maintaining a competitive, performance-based compensation program. However, tax consequences are subject to many factors (such as changes in the tax laws and regulations or interpretations thereof and the timing and nature of various decisions by officers regarding stock options) that are beyond the control of either the Compensation Committee or the Company. In addition, the Compensation Committee believes that it is important for it to retain maximum flexibility in designing compensation programs that meet its stated objectives and fit within the Compensation Committee’s guiding principles. Also, the actual impact of the loss of deduction for compensation paid to the CEO and the other three most highly compensated executives over the $1 million limitation may be small and have a de minimis impact on the Company’s overall tax position. For these and other reasons, the Compensation Committee, while considering tax deductibility as a factor in determining compensation, will not limit compensation to those levels or types that will be deductible.

Internal Revenue Code Section 409A. The Company reviews its compensation plans and programs for compliance with Section 409A of the Internal Revenue Code and the relevant Treasury Resolutions regarding nonqualified deferred compensation.

Impact of FASB ASC Topic 718. The accounting standards applicable to the various forms of long-term incentive plans under Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) Topic 718 (formerly FASB Statement 123R) is one factor that the Company considers in the design of its long-term equity incentive programs. The Company monitors its FASB ASC Topic 718 expense to ensure that it is reasonable, but expense will not be the most important factor in making decisions about our long-term incentive plans.

2018 PROXY STATEMENT

Severance/Change in Control Agreements

In light of competitive market practices, based on the findings in a study completed by the Compensation Committee’s independent consultant, the Compensation Committee has approved severance agreements with the named executive officers, which provide for certain benefits upon an involuntary termination. These agreements promote retention of high-performing individuals and also assist in recruiting and retaining key employees by providing competitive arrangements.

The severance agreements with each of the named executive officers provide for the payment of severance compensation and benefits to the covered executive officer (the “covered executive”) if the Company terminates the covered executive’s employment without “cause” or if the covered executive resigns for “good reason.” For this purpose, “cause” and “good reason” are defined in the same manner as in the change-in-control severance agreements discussed above. Upon such a termination, the covered executive will be entitled to receive the following:

∎

a lump-sum cash payment equal to the sum of (1) the covered executive’s accrued base salary and accrued vacation pay plus (2) if not previously paid, the covered executive’s annual cash incentive earned for the preceding fiscal year;

∎

a lump-sum cash payment equal to 2 times for the CEO and 1 time for the other named executive officers the sum of (1) the covered executive’s base salary then in effect, plus (2) an amount equal to the greater of (a) the covered executive’s targeted annual cash incentive for the year immediately prior to the year in which his employment terminates, or (b) the covered executive’s actual annual cash incentive earned for the preceding year;

∎

continued health and dental plan benefits on the same terms and conditions as though the covered executive had remained an active employee (or payment of the necessary amount to obtain equivalent coverage if Company coverage is not possible), for the shorter of 12 months or until equivalent coverage is obtained from a new employer; and

∎

accelerated vesting of all outstanding long-term equity incentive awards, including, but not limited to, stock options, stock appreciation rights, restricted stock, restricted stock units and performance shares (at the targeted payment level).

If the covered executive’s employment is terminated during a change-in-control protection period under his change-in-control severance agreement, described below, the covered executive will be entitled to receive the severance payments specified under that agreement instead of the foregoing payments under his severance agreement.

The covered executive is not entitled to any additional severance payments or benefits under his severance agreement if his employment is terminated by the Company for cause, by the covered executive without good reason, or if it terminates due to his death or disability.

The term of each severance agreement is three years, unless it is extended by mutual agreement of the parties. The current term of the severance agreements ends on August 3, 2020.

In light of competitive market practices, based on the findings in a sturdy completed by the Compensation Committee’s independent consultant, the Compensation Committee has approved change in control severance agreements for the CEO and the other named executive officers. The agreements are intended to help retain these named executive officers, maintain a stable work environment and provide economic security to certain key employees in the event of termination of their employment in connection with a change in control.

Pursuant to these agreements, if, within the period beginning 90 days before and ending two years after a “change in control” of the Company, (1) the employment of the executive, who we refer to as a “covered executive,” is terminated by the Company (other than a termination for “cause” or by reason of death or disability) or (2) if the covered executive terminates his employment for “good reason” (either event constituting a “double trigger”), the covered executive will receive severance benefits.

∎

For this purpose, “cause” includes events specified in the change-in-control severance agreement, including the covered executive’s willful or grossly negligent misconduct that is materially injurious to the Company,

TREX COMPANY, INC.

2018 PROXY STATEMENT

SEVERANCE/CHANGE IN CONTROL AGREEMENTS

embezzlement or misappropriation of funds or property of the Company, conviction of a felony or any crime involving fraud, dishonesty, moral turpitude or breach of trust, or willful failure or refusal to devote full business time and attention to the performance of duties.

∎

For this purpose, “good reason” includes events specified in the change-in-control severance agreement, including a material and adverse change in the covered executive’s status or position with the Company, a 10% or greater reduction in the covered executive’s aggregate base salary and targeted annual incentive other than as part of general reduction in executive compensation, the failure by the Company or any successor to continue in effect any employee benefit plan in which the covered executive is participating other than as a result of normal expiration of such plan in accordance with its terms, or the relocation of the covered executive’s office more than 50 miles from the current office and further than his then-current residence.

Upon such termination, the covered executive will receive:

∎

a lump-sum cash payment equal to the sum of (1) the covered executive’s accrued base salary and accrued vacation pay, plus (2) if not previously paid, the covered executive’s annual cash incentive earned for the preceding fiscal year, plus (3) the covered executive’s targeted annual cash incentive for the year in which the severance occurs, pro-rated based upon the number of days he was employed during such year;

∎

a lump sum severance payment equal to 2.99 times for the CEO and 1.5 times for the other named executive officers the sum of (1) the covered executive’s annual base salary (in effect immediately prior to the change in control or termination, whichever is greater), plus (2) the greater of (a) the covered executive’s target annual cash incentive for the year immediately prior to the year in which the change in control occurs, (b) the covered executive’s target annual cash incentive for the year of the termination of employment, or (c) the covered executive’s actual annual cash incentive for the last fiscal year immediately prior to the year of the termination of employment; and

∎

continuation of group health and dental insurance, and group life insurance, on the same terms and conditions as though the covered executive had remained an active employee (or payment of the necessary amount to obtain equivalent coverage if Company coverage is not possible), for the shorter of 18 months or until coverage is obtained from a new employer.

Notwithstanding the foregoing, each agreement provides that, to the extent necessary to avoid imposition of the excise tax under Section 4999 of the Internal Revenue Code in connection with a change in control, the amounts payable or benefits to be provided to the covered executive shall be reduced such that the reduction of compensation to be provided to the covered executive is minimized. In applying this principle, the reduction shall be made in a manner consistent with the requirements of Section 409A of the Internal Revenue Code, and where two economically equivalent amounts are subject to reduction but payable at different times, such amounts shall be reduced on a pro rata basis (but not below zero).

If a change in control occurs during the term of these agreements, the covered executive will be entitled to accelerated vesting of all outstanding long-term equity incentive awards, including, but not limited to, stock options, stock appreciation rights, restricted stock, restricted stock units, and performance shares (at the targeted payment level) (whether or not there is a loss of employment).

A change in control is generally defined as (1) the acquisition by any person or entity of 35% of Trex Company’s outstanding stock, (2) a merger where the stockholders of the Company immediately prior to the merger would not own at least 50% of the outstanding stock of the Company after such merger, (3) a sale of all or substantially all of the assets of the Company, or (4) during any two-year period, the directors in office at the beginning of such period ceasing to be a majority of the board, unless the nomination of each new director during such period was approved by at least two-thirds of the directors in office at the beginning of such period.

The table below reflects the amount of compensation payable to the CEO and each of the Company’s other named executive officers in the event of termination of such officer’s employment (including termination by death or disability) and/or a change in control. The amounts shown assume that such termination and/or change in control was effective as of December 31, 2017 and thus includes amounts earned through such date. These figures are estimates of the amounts which would be paid to the officers upon their termination and/or a change-in-control. The actual amounts to be paid can only be determined at the time of such event.

The Company’s Compensation Policies and Practices as They Relate to Risk

The Company does not believe that its compensation policies and practices create risks that are reasonably likely to have a material adverse effect on the Company. The annual cash incentive compensation plan described in the Compensation Discussion and Analysis section above is based upon achievement of annual financial targets, and potential cash incentive compensation opportunities are tempered so as not to place a disproportionate incentive on short-term financial results. In addition, the long-term equity incentive plan provides appropriate motivation to achieve long-term financial results as well, given that the ultimate value of the award is based upon the future value of the Company stock, and such awards constitute a significant portion of each executive’s total compensation package. The Company has constructed the determinant performance factors in short- and long-term performance plans such that they balance focus on performance metrics with strong links to stockholder value creation and overall company performance, which we believe avoids any potential risks that may result from an imbalance in performance metrics.

Report of the Audit Committee of the Board of Directors of Trex Company, Inc.

During the fiscal year ended December 31, 2017, the Audit Committee of the Board of Directors (the “Board”) of Trex Company, Inc. (the “Company”) reviewed with the Company’s financial managers, the internal auditors and Ernst & Young LLP (“Ernst & Young”), the Company’s independent registered public accounting firm, the scope of the annual audit and audit plans, the results of internal and external audit examinations, the evaluation of the Company’s system of internal control, the quality of the Company’s financial reporting, and the Company’s process for legal and regulatory compliance. The Audit Committee also monitored the progress and results of the testing of internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act of 2002.

Management is responsible for the Company’s system of internal control, the financial statements and the financial reporting process, and the assessment of the effectiveness of internal control over financial reporting. Ernst & Young is responsible for performing an integrated audit and issuing reports on the following: (1) the Company’s consolidated financial statements, and (2) the Company’s internal control over financial reporting. As provided in its charter, the Audit Committee’s responsibilities include monitoring and overseeing these processes. The Audit Committee has reviewed and discussed the audited financial statements for the fiscal year ended December 31, 2017 with management. Management has excluded Trex Commercial Products, Inc., the wholly-owned subsidiary of Trex Company, Inc. which is included in the Consolidated Financial Statements, from its assessment of internal control over financial reporting as of December 31, 2017, because it was formed to acquire certain assets and assume certain liabilities of Staging Concepts Acquisition, LLC in a business combination on July 31, 2017.

Consistent with this oversight responsibility, Ernst & Young reports directly to the Audit Committee. The Audit Committee appointed Ernst & Young as the Company’s independent registered public accounting firm and approved the firm’s compensation.

The Audit Committee discussed with Ernst & Young the matters required to be discussed by the New York Stock Exchange, the U.S. Securities and Exchange Commission, the Public Company Accounting Oversight Board, and the American Institute of Certified Public Accountants’ Statement on Auditing Matters No. 61, Communication with Audit Committee, as amended, as adopted by the Public Company Accounting Oversight Board. In addition, the Audit Committee has received from Ernst & Young the written disclosures and the letter required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountants’ communications with the Audit Committee concerning independence, and discussed with Ernst & Young the firm’s independence from the Company and its management.

In reliance on the review and discussions referred to above, the Audit Committee recommended to the Board, and the Board has approved, the inclusion of the audited financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2017, for filing with the U.S. Securities and Exchange Commission.

Advisory Vote on Executive Compensation

(Proposal 2)

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables our stockholders to vote to approve, on an advisory (non-binding) basis, the compensation of our named executive officers as disclosed in this proxy statement, in accordance with the SEC’s rules.

As described in detail under the heading “Compensation Discussion and Analysis,” our executive compensation programs are designed to attract, motivate, and retain our named executive officers, who are critical to our success. Under these programs, our named executive officers are rewarded for the achievement of specific annual, long-term and strategic goals, corporate goals, and the realization of increased stockholder value. Please read the “Compensation Discussion and Analysis” section above for additional details about our executive compensation programs, including information about the fiscal year 2017 compensation of our named executive officers.

The Compensation Committee periodically reviews the compensation programs for our named executive officers to determine and confirm that they achieve (and continue to achieve) the desired goals of aligning our executive compensation structure with our stockholders’ interests and current market practices.

We are asking our stockholders to indicate their support for our named executive officer compensation as described in this proxy statement. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to vote on our named executive officers’ compensation. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement.

The say-on-pay vote is advisory, and therefore not binding on the Company, the Compensation Committee or our Board. Our Board and our Compensation Committee value the opinions of our stockholders, and the Compensation Committee will consider the results of the vote in future decisions relating to executive compensation.

Approval of Proposal 2

Approval of this proposal will require the affirmative vote of holders of a majority of the shares of common stock present in person or represented by proxy and entitled to vote on such matter at the annual meeting. Unless authority to do so is withheld, it is the intention of the persons named in the proxy to vote such proxy FOR this proposal. Abstentions from voting on this proposal will have the same effect as a vote against this proposal. Brokers may vote their shares on this proposal if they have voting instructions from the beneficial owners of the shares. Broker non-votes will not be treated as votes cast on this matter, and therefore will not have any effect on determining the outcome.

The Board unanimously recommends that the stockholders of the Company vote FOR the approval of the compensation of our named executive officers, as disclosed in this proxy statement pursuant to the compensation disclosure rules of the U.S. Securities and Exchange Commission.

2018 PROXY STATEMENT

Approval of the Second Certificate of Amendment to the Restated Certificate of Incorporation of Trex Company, Inc. to Increase the Number of Authorized Shares of Common Stock

(Proposal 3)

The Second Certificate of Amendment to the Trex Company, Inc. Restated Certificate of Incorporation is attached to this Proxy Statement as Appendix A (the “Amendment”). The purpose of the Amendment is solely to modify Article IV of the Restated Certificate of Incorporation of the Company to increase the number of authorized shares of common stock, par value $.01 per share, from 80,000,000 shares to 120,000,000. The Amendment would change Article IV specifically as follows:

“The Corporation shall have the authority to issue a total of one hundred twenty three million (123,000,000) shares of capital stock, each with a par value of $0.01, consisting of one hundred twenty million (120,000,000) shares of common stock and three million (3,000,000) shares of preferred stock.”

The authorized capital stock of the Company presently consists of 83,000,000 shares of capital stock, each with a par value of $0.01 per share, consisting of 80,000,000 shares of common stock and 3,000,000 shares of preferred stock. As of December 31, 2017, 29,428,430 shares of common stock were outstanding, 5,493,681 shares were held by the Company as treasury shares, and 2,737,379 shares were reserved for issuance under the Company’s stock incentive plans for directors, officers and other key employees.

The terms of the additional authorized shares of common stock will be identical to those of the currently outstanding shares of common stock. The relative rights and limitations of the shares of issued common stock would remain unchanged under this proposal. This Amendment will not alter the number of shares issued on the date of stockholder approval.

The Board of Directors believes that it is in the Company’s best interests to increase the number of authorized shares of common stock to give the Company greater flexibility in the future should certain opportunities arise such as the following:

future stock splits;

raising capital through the sale of common stock;

acquiring other companies, businesses or products in exchange for shares of common stock;

attracting and retaining employees by the issuance of additional securities under the Company’s various equity compensation plans; or

other transactions and corporate purposes that the Board and/or the Compensation Committee deems are in the Company’s best interest.

The additional authorized shares would enable the Company to act quickly in response to opportunities that may arise for these types of transactions. For example, on April 7, 2014, the Company completed a 2 for 1 stock split in the form of a stock dividend. Between April 7, 2014 and December 31, 2017, the Company’s common stock increased in market price from $36.42 to $108.39. It is possible in the near future that the Board of Directors may resolve to do another 2 for 1 stock split in the form of a stock dividend. If the Board approved a 2 for 1 stock split using the currently authorized numbers, approximately 75,300,000 shares would be outstanding, held by the Company as treasury shares, or reserved for issuance under the Company’s stock incentive plan after such stock split. Without approving the Amendment, the Company would have only 4,700,000 authorized shares of common stock available for any future issuances for the other possibilities described above. This may severely impede the ability of the Board and management to take action to achieve a valid business purpose that would create value for the Company and the stockholders. If the Amendment is approved, the number of authorized and unissued shares of common stock available for future issuance would increase to 44,700,000 shares if the Company did a 2 for 1 stock split.

The Company is not proposing to increase its authorized shares of common stock in order to impede a change in control of the Company and the Company is not aware of any current efforts to acquire control of the Company.

However, under certain circumstances, the additional shares of common stock could be issued by the Company to defend against, or otherwise respond to, a hostile takeover bid. For instance, the Company could issue shares of common stock to dilute the stock ownership of a person or entity seeking to obtain control of the Company. The Company could also respond to an unsolicited takeover bid by issuing, in a private placement or otherwise, a significant portion of its securities with purchasers who might align with the Board in response to a specific change in control transaction affecting the Company. Moreover, the issuance of shares of common stock to persons friendly to the Board could make it more difficult to remove incumbent officers and directors from office even if such change could be considered favorable to stockholders generally.

Nevertheless, while the issuance of shares of common stock may have anti-takeover ramifications, the Board believes that the financial flexibility offered by Amendment outweighs any such disadvantages. To the extent that the Amendment may have anti-takeover effects, the Amendment may encourage persons seeking to acquire the Company to negotiate directly with the Board enabling the Board to consider the proposed transaction in a manner that best serves the stockholders’ interests.

The issuance of the additional shares of common stock contemplated by this proposal also could have the effect in certain circumstances of, among other things, diluting earnings per share, book value per share or voting power of the currently outstanding shares of common stock

As of the date of this proxy statement, the Company has no current plans, arrangements or understandings regarding the additional shares that would be authorized pursuant to this proposal; however, the Company reviews and evaluates potential capital raising activities, transactions and other corporate actions on an on-going basis to determine if such actions would be in the best interests of the Company and its stockholders.

Approval of Proposal 3

Under Delaware law, approval of the Amendment requires the affirmative vote of a majority of the shares of common stock issued and outstanding. Unless authority to do so is withheld, it is the intention of the persons named in the proxy to vote such proxy FOR this proposal. Abstentions and broker non-votes will have the same effect as a vote against this proposal.

The Board unanimously recommends that the stockholders of the Company vote FOR approval of the Second Certificate of Amendment to the Trex Company, Inc. Restated Certificate of Incorporation to increase the number of authorized shares of Common Stock from 80,000,000 to 120,000,000.

2018 PROXY STATEMENT

Ratification of Appointment of Independent Registered Public Accounting Firm for the 2018 Fiscal Year

(Proposal 4)

The Audit Committee of the Board has appointed Ernst & Young LLP as the Company’s independent registered public accounting firm for the Company’s fiscal year ending December 31, 2018. The Board is submitting this appointment for stockholder ratification at the annual meeting.

A representative of Ernst & Young will attend the annual meeting, will have the opportunity to make a statement and will be available to respond to appropriate questions from stockholders.

The Company’s bylaws do not require that stockholders ratify the appointment of Ernst & Young as the Company’s independent registered public accounting firm. The Company is asking its stockholders to ratify this appointment because it believes such a proposal is a matter of good corporate practice. If the stockholders do not ratify the appointment of Ernst & Young, the Audit Committee will reconsider whether or not to retain Ernst & Young as the Company’s independent registered public accounting firm, but may determine to do so. Even if the appointment of Ernst & Young is ratified by the stockholders, the Audit Committee may change the appointment at any time if it determines that a change would be in the best interests of the Company and its stockholders.

Approval of Proposal 4

Approval of this proposal will require the affirmative vote of holders of a majority of the shares of common stock present in person or represented by proxy and entitled to vote on such matter at the annual meeting. Unless authority to do so is withheld, it is the intention of the persons named in the proxy to vote such proxy FOR this proposal. Abstentions from voting on this proposal will have the same effect as a vote against this proposal. Broker non-votes will not be treated as votes cast on this matter, and therefore will not have any effect on determining the outcome.

The Board unanimously recommends that the stockholders of the Company vote FOR the ratification of the appointment of Ernst & Young LLP as the Company’s independent registered public accounting firm for the 2018 fiscal year.

Fees

Ernst & Young LLP served as the Company’s independent registered public accounting firm for the Company’s fiscal years ended December 31, 2017 and 2016. The following sets forth the aggregate fees billed by Ernst & Young to the Company for fiscal years 2017 and 2016.


	2017	2016
Audit services	$942,060	$788,000
Audit-related services	$94,680	—
Tax services	—	—
All other services	$280,800	$416,369
Total	$1,317,540	$1,204,369

The Audit Committee considered whether Ernst & Young’s provision of non-audit-related services is compatible with maintaining Ernst & Young’s independence, and determined it was.

Audit Services. Audit services include services performed by Ernst & Young to comply with generally accepted auditing standards related to the audit and review of the Company’s consolidated financial statements. The audit fees shown above for the 2017 and 2016 fiscal years were incurred principally for services rendered in connection with the audit of the Company’s consolidated financial statements and associated SEC filings, the issuance of opinions on the Company’s internal control over financial reporting and quarterly reviews.

Audit-Related Services. Audit-related services include assurance and related services that are traditionally performed by independent registered public accounting firms.

Tax Services. The tax fees shown above were incurred in connection with the preparation of the Company’s tax returns and corporate tax consultations.

All Other Services. These fees were incurred in connection with a strategic market assessment provided by an affiliate company of Ernst & Young.

Pre-Approval Policy

The Audit Committee pre-approves all audit and permissible non-audit services provided by the Company’s independent registered public accounting firm. These services may include audit services, audit-related services, tax and other services. Pre-approval on other than an engagement-by-engagement basis is generally provided for up to one year, and any pre-approval is detailed as to the particular service or category of services and is generally subject to a specific budget. The independent registered public accounting firm and management are required to report periodically to the Audit Committee regarding the extent of services provided by such firm in accordance with this pre-approval and the fees for the services performed to date. The Audit Committee also may pre-approve particular services on an engagement-by-engagement basis.

During the year, circumstances may arise when it may become necessary to engage the independent registered public accounting firm for additional services not contemplated in the original pre-approval. In those instances, the Audit Committee requires specific pre-approval before engaging the independent registered public accounting firm. The Audit Committee has the authority to delegate pre-approval authority to a subcommittee of the Audit Committee consisting of one or more of its members.

All services provided to the Company by Ernst & Young LLP during fiscal 2017 and 2016 were pre-approved by the Audit Committee in accordance with this policy.

Transactions with Related Persons

The Company’s Board has adopted a written policy for the approval of transactions with related persons. The policy requires Audit Committee approval or ratification of transactions which involve more than $120,000 in which the Company is a participant and in which a Company director, nominee for director, executive officer, greater than 5% stockholder, or an immediate family member of any of the foregoing persons has a direct or indirect material interest. In reviewing the related party transaction, the Audit Committee will, after reviewing all material information regarding the transaction, take into account, among other factors it deems appropriate, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances and the extent of the related person’s interest in the transaction. The policy includes standing pre-approval for the following related person transactions:

∎

any transaction with another company at which a related person’s only relationship is as an employee (other than an executive officer), director or beneficial owner of less than 10% of that company’s equity securities, if the aggregate amount involved does not exceed the greater of $1,000,000, or 2% of that company’s total annual revenues;

∎

any charitable contribution, grant or endowment by the Company to a charitable organization, foundation or university at which a related person’s only relationship is as an employee (other than an executive officer) or a director, if the aggregate amount involved does not exceed the lesser of $1,000,000, or 2% of the charitable organization’s total annual receipts;

∎

any transaction, such as dividends paid on the common stock, in which the related person’s interest arises solely from the ownership of the Company’s common stock and all holders of the Company’s common stock received the same benefit on a pro rata basis; and

∎

any transaction with a related party involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar services.

There are no transactions with related persons to report for fiscal 2017.

Delivery of Documents to Stockholders Sharing an Address

If you and other residents at your mailing address own common stock through a broker or bank in “street name,” your broker or bank may have sent you a notice that your household will receive only one annual report to stockholders and proxy statement or a Notice of Internet Availability indicating proxy materials are available on the internet for each company in which you hold shares through that broker or bank. The practice of sending only one copy of an annual report to stockholders and proxy statement or a Notice of Internet Availability is known as “householding.” If you did not respond that you did not want to participate in householding, you were deemed to have consented to the process. If the foregoing procedures apply to you, your broker has sent one copy of the Notice of Internet Availability to your address. You may revoke your consent to householding at any time by sending your name, the name of your brokerage firm, and your account number to Broadridge, Householding Department, 51 Mercedes Way, Edgewood, New Jersey 11717 (telephone number: 1-800-542-1061). In any event, if you did not receive an individual copy of the Company’s annual report to stockholders or this proxy statement, and wish to do so, the Company will send a copy to you if you address your written request to Trex Company, Inc., 160 Exeter Drive, Winchester, Virginia 22603-8605, Attention: Secretary, or call the Company at 540-542-6300. If you are receiving multiple copies of the annual report to stockholders and proxy statement or Notice of Internet Availability, you can request householding by contacting the Company in the same manner. The Company encourages you to participate in this program. It will reduce the volume of duplicate information received at your household, as well as reduce the Company’s expense.
