TWP Trex CO., Inc.

Trex Company, Inc. (NYSE: TWP), manufacturer and distributor of Trex� decking, railing, fencing and trim, today announced financial results for the fourth quarter and fiscal year ended December 31, 2008.

For fiscal year 2008, Trex Company reported net sales of $329.2 million, compared to net sales of $329.0 million for fiscal year 2007. The Company reported net income of $13.6 million, or $0.90 per diluted share, for 2008 compared to a net loss of $75.9 million, or $5.10 per diluted share, for 2007. The Company�s full-year 2007 results were adversely affected by charges totaling $92.0 million, of which $37.8 million were recognized in net sales. Before giving effect to these charges, net sales for 2007 totaled $366.8 million.

Net sales for the fourth quarter of 2008 totaled $29.3 million compared to net sales of $30.3 million for the 2007 fourth quarter. The Company reported a net loss for the 2008 fourth quarter of $10.0 million, or $0.67 per diluted share, compared to a net loss of $41.0 million, or $2.75 per diluted share, for the fourth quarter of 2007. The Company�s fourth-quarter 2007 results were adversely affected by charges totaling $19.3 million. Of these charges, $12.5 million were recognized in net sales. Before giving effect to these charges, net sales for the 2007 fourth quarter totaled $42.8 million.

The Company recognized an income tax benefit of $0.8 million and $1.0 million in the 2008 fourth quarter and full year, respectively. The low 2008 effective tax rate, as compared to 2007, was primarily due to the recognition of a benefit resulting from the realization of a portion of the Company�s previously reserved deferred tax assets.

President and CEO Ronald W. Kaplan commented, �As our results clearly demonstrate, 2008 was an excellent year for Trex, during which we made significant progress in restoring the company to financial health and grew shareholder value based on our four guiding principles � providing a best-in-class product offering, expanding our distribution presence, increasing our brand leadership and advancing our low-cost competitive advantage. Our new products, including Trex Escapes� ultra-low maintenance decking and grooved Trex Brasilia� with the Trex Hideaway� fastening system, were well received, and the many cost efficiencies, productivity and process improvements we implemented also contributed to the successful progress of our business turnaround. All of us are very proud of the long way Trex has come over the past 12 months, especially given the extremely difficult economic environment.

�Although we reported a net loss in the 2008 fourth quarter � as Trex typically does due to the highly seasonal nature of outdoor home improvements � on a pro forma basis, our results improved significantly over the same period in 2007. Our gross margin for fiscal year 2008 climbed to 27.8% or 29.1% on a pro forma basis from 12.0% or 24.1% on a pro forma basis for the 2007 year. Free cash flow for the 2008 year (defined as cash provided by, or used in, operating activities less cash used for capital expenditures) rose substantially to $25.2 million from negative $25.2 million in 2007 and we ended 2008 with a cash balance of $23.2 million, greatly enhancing our financial and operational flexibility in the coming year.

�Moving forward we will complete the business turnaround that we began a year ago and maintain our focus on long-term growth in shareholder value by responding to consumers� desire for attractive, high quality outdoor living products. We will continue building our exceptional brand recognition, best-in-class products, and leading distribution presence, as well as leveraging our low-cost manufacturing advantage. An important goal will be to provide people more choices that enable them to build decks, railing and fences that are both distinctive and provide a value proposition against traditional wood. We are also assessing strategies that will enable Trex to take advantage of today�s tough competitive conditions and gain additional market share.

�While the current economic turmoil makes it difficult to forecast net sales in 2009, we have established a target of $60 million in net sales for the first quarter. This estimate reflects the fact that we expect a shift in purchasing patterns as our customers order based more on pull-through demand due to the current economic conditions and the redesign of our early buy sales program. We expect this to shift sales activity in 2009 from the first to the second and third quarters. Throughout 2009, we will maintain our strong focus on free cash flow through earnings and working capital management, and will keep inventory and capital expenditures low as compared to historical levels.�
