Trex Company Reports First Quarter 2008 Net Sales of $119.5 Million and EPS of $0.60

No Borrowings Against Revolver; Positive Cash Balance of $1.9 million as of May 5, 2008

WINCHESTER, Va.--(BUSINESS WIRE)--Trex Company, Inc. (NYSE: TWP), manufacturer and distributor of Trex® decking, railing, fencing and trim, today announced financial results for the first quarter ended March 31, 2008.

Net sales for the first quarter of 2008 totaled $119.5 million, compared to net sales of $115.9 million for the first quarter of 2007, representing a 3.1% increase. The Company reported net income for the 2008 first quarter of $8.9 million, or $0.60 per diluted share, compared to net income of $3.7 million, or $0.25 per diluted share, for the 2007 first quarter, representing a 140% increase.

The Company had an effective tax rate of approximately 1% for the first quarter of 2008 as a result of recognizing a decrease in the valuation allowance against the deferred tax asset, which accounted for $0.22 of the increase in earnings per share.

President and Chief Executive Officer Ronald W. Kaplan commented, “Trex’s expanding distribution presence, continued commitment to quality, and the notable power of the Trex brand enabled us to increase sales revenue despite the weakening economy and continued softness in the building materials industry. In addition, our improved gross margin reflects our successful focus on productivity and cost containment initiatives.”

“We managed liquidity well during the 2008 first quarter, ending the period with $22 million of borrowings on our revolving line of credit, which has a maximum borrowing capacity of $70 million during the ‘early buy’ sales season. As of May 6, 2008, we have paid down all borrowings on our revolving line of credit and are carrying a positive cash balance.”

Mr. Kaplan continued, “The first quarter of 2008 represents an excellent first step to our near-term goal of restoring Trex Company’s financial health and providing a competitive return to our shareholders. The measures we took in the first quarter – including rightsizing the Company, recruiting new management, controlling costs and enhancing operating and financial controls – have established a solid foundation for delivering improved financial results.

“We are pleased with the performance of our early buy sales program, which is designed to meet current demand as well as place sufficient product into distribution before the deck-building season moves into high gear. At the same time, given the inclement winter weather in many parts of the U.S., which delayed many outdoor projects, coupled with building material dealers choosing to operate with depressed inventory levels and the uncertain economic outlook, we are cautious regarding second quarter revenue. We are therefore projecting second quarter 2008 revenue to be 23% to 33% below the level attained during the second quarter of 2007, when net sales totaled $118.8 million. We anticipate that the lower effective tax rate realized in the first quarter of 2008 will continue for the remainder of the year. We further expect that the effects of lower sales will be partially mitigated by the enhanced efficiency and cost control we have achieved.”
