   Trex Company Announces Fourth Quarter and Year-End 2005 Results

    WINCHESTER, Va.--(BUSINESS WIRE)--Feb. 16, 2006--Trex Company,
Inc. (NYSE:TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the fourth quarter and full year ended
December 31, 2005.
    Net sales for the fourth quarter of 2005 totaled $44.0 million,
compared to net sales of $29.6 million for the fourth quarter of 2004,
which represented a 49% increase. The Company reported a net loss for
the 2005 fourth quarter of $10.1 million, or $0.68 per diluted share,
compared to a net loss of $0.4 million, or $0.02 per diluted share,
for the 2004 fourth quarter.
    For the full 2005 year, Trex Company reported net sales of $294.1
million, compared to net sales of $253.6 million for 2004, which
represented a 16% increase. Net income for 2005 was $2.5 million, or
$0.17 per diluted share, compared to net income of $ 27.2 million, or
$1.83 per diluted share, for 2004.
    Chairman and Chief Executive Officer Anthony J. Cavanna commented,
"We are pleased with Trex's strong revenue growth in the fourth
quarter, which reflected low inventory levels in the channel combined
with favorable weather conditions and our dealers' anticipation of a
strong 2006.
    "This positive top-line performance was offset by lower
utilization of the company's manufacturing facilities and the
resulting underabsorption of fixed plant costs. Continued increases in
the cost of plastic raw materials and a series of ongoing initiatives
to improve product quality and packaging also negatively affected our
bottom line.
    "2005 was clearly a challenging year for Trex, due in great part
to the aggressive manufacturing and new product agenda we set for the
company. Our plan for 2006 is to achieve better absorption of fixed
overhead by bringing plant utilization up to a more normal level. We
successfully opened our facility in Olive Branch, Mississippi in the
second quarter of 2005, and the new facility is already producing at
rates and quality levels comparable to those of our Winchester and
Fernley plants. Rather than introducing any new decking products in
2006, we will focus on achieving more consistent and efficient plant
production of our Trex Accents(R), Trex Brasilia(TM), and Trex Artisan
Series Railing(TM) products, all of which have been enthusiastically
received by the market. Although investing in our brand is still an
important priority for Trex, we expect total SG&A costs to decline as
a percentage of net sales in 2006."
    Mr. Cavanna concluded, "As a result of the many steps we have
taken to enhance product quality, improve our manufacturing operations
and achieve better control of our costs, we believe Trex is well
positioned to continue to lead the conversion of the market from wood
to composite decking. For the first half of 2006, we expect net sales
to range from $220 million to $230 million and earnings per diluted
share to range from $0.57 to $0.62. This compares to net sales of $173
million and earnings per diluted share of $0.50 in the first half of
2005."
    Trex will hold a conference call to discuss its fourth-quarter and
year-end 2005 results on Thursday, February 16 at 10:00 a.m. ET. A
live webcast of the conference call will be available to all investors
at the Trex Company website at www.trex.com. The call will also be
simulcast at www.streetevents.com.
