Trex Company Updates Full Year Financial Guidance and

Announces Preliminary Third Quarter 2003 Results

WINCHESTER, Va.– September 29, 2003 — Trex Company, Inc. (NYSE: TWP), manufacturer of Trex^® decking and railing, today updated its financial guidance for 2003. For the full year, the Company expects revenue to range between $185 million to $190 million, compared to its previous guidance of approximately $200 million and 2002’s revenue of $167.1 million. It expects net income for 2003 to range between $1.40 to $1.43 per share, compared to the previous estimate of $1.63 to $1.66 per share and actual net income of $1.16 per share in 2002.

The Company attributed the updated guidance primarily to continued poor weather conditions throughout many parts of the country, including, most recently, Hurricane Isabel. In addition, net income has been adversely affected by the cost of plastic raw materials. Although these third-quarter costs have declined compared to the second quarter of 2003, thus far in the second half of 2003, poly costs have been higher than previously anticipated.

Based on a preliminary review, the Company expects revenue for the third quarter of 2003 to be between $39 million and $40 million, compared to last year’s third quarter revenue of $49.5 million. The Company expects net income for the third quarter to be a minimum of $0.33 per share, compared to $0.43 per share for last year’s third quarter.

Trex Company President Robert Matheny commented, “Although we have lowered our projections for the full year, we believe the primary causes of this temporary slowdown are behind us. Our dealers and distributors are reporting increases in sales volume and we are maintaining a sufficient factory finished goods inventory level to meet a potentially strong sales level in the fourth quarter as well as to support a strong “early buy” program in the first quarter of 2004. Our marketing efforts remain focused on establishing the Trex brand as the standard in the $2.0 billion decking market.”

Trex will release its third-quarter results after the market closes on Monday, October 27 and will hold a conference call to discuss those results on Tuesday, October 28 at 11:00 a.m. ET. A live webcast of the conference call will be available to all investors at the Trex Company web site at www.trex.com. The call will also be simulcast at www.streetevents.com.
