Robert G. Matheny Retiring for Health Reasons

The Board of Directors of Trex Company, Inc. (NYSE: TWP), manufacturer of Trex(R) decking and railing, today announced the appointment of Anthony J. Cavanna as the Company's chairman and chief executive officer. One of the original four executives who formed Trex in 1996 and took the Company public in 1999, Mr. Cavanna has served as a director since 1998 and was executive vice president and chief financial officer from 1998 through 2003. Mr. Cavanna succeeds Robert G. Matheny, who is retiring for health reasons. Mr. Matheny will remain on the Trex board of directors.

The Board also announced that Andrew U. Ferrari has been appointed to the positions of president and chief operating officer. Mr. Ferrari, also one of the Company's original executives, has served as a director of Trex since 1998 and was executive vice president of marketing and business development from 2001 to 2003. Prior to that, he served as Trex Company's executive vice president of sales and marketing.

Mr. Cavanna commented, "On behalf of the entire board, I would like to thank Bob for his leadership of Trex and his many extraordinary contributions to establishing our Company as the leader in composite decking and railing. He successfully led many of the Company's most important strategic initiatives. We look forward to his continued participation and guidance as he continues as a member of the board.

"Over the past five years, Trex's sales have more than tripled, rising from $74 million in 1999 to $254 million in 2004. We have successfully introduced many exciting new products and choices for consumers, expanded our distribution channels, and improved our manufacturing and technological capabilities. Trex's growth prospects have never been stronger, and Andy and I are very excited about the many opportunities that exist to continue to build value for our shareholders."

Mr. Cavanna and Mr. Ferrari have been leaders of the business since Trex was formed through a leveraged buy-out from Mobil Oil Corporation in 1996. Mr. Cavanna was responsible for the financial plan that led to the Company's listing on the New York Stock Exchange in 1999 and for overseeing the Company's financial planning and operations for the next four years. Mr. Ferrari developed Trex's marketing strategy to create a brand in what was previously a commodity business and guided the growth of the company's sales effort from a handful of distributors to a national network of more than 90 Trex distributors and 3,000 retail dealers.

From 1962 to 1996, Mr. Cavanna held a variety of high-level positions with Mobil Chemical, including group vice president, vice president-planning and finance, and vice president of Mobil Chemical and general manager of its Films Division Worldwide. He currently serves as a director of UltraLife Batteries Co., Inc. and chairman of its Audit and Finance Committee.

Mr. Ferrari held various positions with Mobil Chemical Company from 1971 to 1996, including director of sales and marketing of the Composite Products Division, new business manager, and marketing director of the Consumer Products Division. He currently serves on the board of trustees of Shenandoah University, as an overseer of Whitman College and as vice chairman of the board of the Grafton School for children with special needs.
