WINCHESTER, Va. –May 7, 2026– Trex Company, Inc. [NYSE:TREX], the world’s largest manufacturer of wood-alternative composite decking and railing, and a leader in high-performance, low-maintenance outdoor living products, today announced financial results for the first quarter of 2026.

Commenting on the quarter, Adam Zambanini, President and CEO, said, “We entered 2026 with strong momentum and a renewed sense of energy and excitement driving the entire organization forward. During the quarter, Trex delivered solid results driven primarily by positive performance in our premium decking portfolio and supported by recent shelf space wins in retail. The Company also delivered strong margins, reflecting product mix, operational efficiencies and cost discipline.”

“During the quarter, we began to take decisive actions aligned with our new long-term strategic priorities, positioning the Company to return to above-industry growth through unmatched innovation, enhanced execution, and renewed investment in our brand, marketing, and customer experience.

Long-Term Strategic Priorities

Trex recently launched five priorities to define a focused, durable path to long-term profitable growth and increased shareholder value:

Create an Unbreakable Bond with End Users: Deepen brand preference and loyalty across consumers, contractors, and pros through superior marketing, product experience, and service.

Launch High‑Performance Innovation: Continue to expand Trex’s leadership in material science and performance through products that represent the next generation of outdoor living solutions.

Optimize Channels for Growth: Strengthen distribution effectiveness and ensure Trex products are readily available across retail, dealer, and pro channels to drive above-market growth.

Lower the Cost of Railing: Drive cost efficiencies and design advancements to enhance margin structure and accelerate share gains in this fast‑growing product line.

Growth Enablement: Invest in the foundation – culture, technology, and talent – that powers sustainable growth. We’re strengthening our organization by aligning around accountability, upskilling for digital and commercial excellence, and fostering an innovation‑driven culture that empowers teams to act with speed and discipline.

“As I noted last quarter, driving growth through innovation remains a key priority. Our recently launched PVC decking product is performing well, leading us to expand into geographies beyond our initial West Coast rollout. The fire-rated product category represents an attractive market opportunity, and we are committed to competing aggressively to capture share in this and other potential growth areas through unmatched product innovation.

“Our refined incentive and marketing programs have been very well received by our channel partners further strengthening these valued relationships. We also are excited about the next phase of our consumer- and pro-focused marketing campaign centered around our “Performance-Engineered for Your Life Outdoors™” brand platform, which launched in May 2025. As we move forward, the Trex brand and our value proposition will become increasingly visible and strategically positioned, with the impact of these programs further enhanced by our investment in digital tools. In the first quarter our digital metrics showed consistent growth across key leading indicators, with high‑intent behaviors meaningfully outpacing overall traffic, signaling more deliberate consumer engagement,” noted Mr. Zambanini.

Q1 2026 Financial Summary

All financial results comparisons made are against the prior-year period unless otherwise noted:

Net sales were $343 million compared to $340 million, an increase of 1%, due to positive price/mix in the quarter.

Gross profit was $139 million with gross margin of 40.5%, compared to gross profit of $138 million and gross margin of 40.5%. There were no adjustments to this year’s gross profit while last year’s adjusted gross profit, which excluded railing conversion costs of approximately $4 million, was $142 million. A favorable mix of higher margin premium decking boards and margin improvement from continued operational excellence programs helped to offset a $4M increase in depreciation expenses related to our Little Rock production facility. The Company experienced no impact on gross margins related to increased oil prices during the quarter.

Selling, general, and administrative expenses were $56 million, representing 16.2% of net sales, compared to $56 million, or 16.5% of net sales in the prior year. Excluding digital transformation costs and Arkansas facility start-up expenses of $1.2 million and $1.5 million, SG&A was $54 million and $55 million, respectively. The Company continued to increase its investment in branding and marketing programs to drive future growth. Other expenses, including personnel and healthcare related expenses, were lower than expected due to cost containment and timing.

Net income was $61 million, or $0.58 per diluted share, compared to net income of $60 million, or $0.56 per diluted share in the prior year. Adjusted net income was $62 million, with adjusted diluted EPS of $0.59, compared to adjusted net income of $64 million with adjusted diluted earnings per share of $0.60.

Adjusted EBITDA of $103 million compared favorably to an adjusted EBITDA of $101 million in the prior year.

Free cash flow was ($143) million, a 39% improvement from last year, reflecting effective management of working capital and lower capital expenditures as we finish the new Little Rock facility.

During the quarter, the Company authorized significant share repurchase programs including a $100 million ASR program and $50 million of additional discretionary repurchases as part of an existing share repurchase authorization. The Company intends to complete the $150 million repurchase program in the second quarter. Share repurchases remain a key aspect of the Company’s capital allocation strategy.

Summary & Outlook

“We continue to anticipate the overall R&R market to be down to flat this year and are closely monitoring any impact on consumer confidence from the ongoing conflict in the Middle East. First quarter financial results were consistent with the cadence we anticipated for the year, with the typical seasonality of the business reflected in both revenue and margins. Additionally, the first quarter reflects continued execution on our commitment to returning capital to shareholders,” said Prith Gandhi, Senior Vice President and Chief Financial Officer.

Based on current visibility, the Company is reaffirming its full year 2026 guidance, shown in the table below, with revenue ranging from $1.185 billion to $1.23 billion and adjusted EBITDA ranging from $315 million to $340 million. The Company also provided second quarter revenue guidance in the range of $388 to $403 million.

The Company expects robust free cash flow generation this year, supported by a meaningful reduction in capital expenditures relative to 2025, as the peak investment phase of the Arkansas campus build-out transitions to an operational phase. Capital expenditure guidance for 2026 is $100 million to $120 million, down from $224 million in 2025. As construction winds down, The Company expects another meaningful increase in free cash flow in 2027 and beyond as capital expenditures return to maintenance levels of roughly 5 to 6% of revenue.

In addition to the execution of its $150 million share repurchase program, the Board of Directors authorized a 10 million share increase to the Company’s existing share repurchase program,

bringing the total potential shares available for repurchase to approximately 13% of Trex’s outstanding shares at the end of the quarter.

Use of Non-GAAP Measures

The Company reports its financial results in accordance with accounting principles generally accepted in the United States (GAAP). To supplement our consolidated financial statements reported on a GAAP basis, we provide the following non-GAAP financial measures, adjusted gross profit, adjusted net income, adjusted diluted earnings per share, earnings before interest, income taxes, depreciation and amortization (EBITDA), adjusted EBITDA and free cash flow. Management believes these non-GAAP financial measures provide investors with additional meaningful financial information that should be considered when assessing our underlying business performance and trends. Further, management believes these non-GAAP financial measures also enhance investors’ ability to compare period-to-period financial results. Non-GAAP financial measures should be viewed in addition to, and not as an alternative for, the Company’s reported results prepared in accordance with GAAP and are not meant to be

considered superior to or a substitute for our GAAP results. Our non-GAAP financial measures do not represent a comprehensive basis of accounting. Therefore, our non-GAAP financial measures may not be comparable to similarly titled measures reported by other companies. Reconciliations of these non-GAAP financial measures to GAAP information are included below. Management uses these non-GAAP financial measures in making financial, operating, compensation and planning decisions and in evaluating the Company’s performance. Disclosing these non-GAAP financial measures allows investors and management to view our operating results excluding the impact of items that are not reflective of the underlying operating performance.
