Trex Q3 2026 Earnings: Sales Rise 26% as Gross Margin Contracts

Trex Company (NYSE: TREX) reported fiscal Q3 2026 net sales of $359.5 million for the quarter ended September 30, up 26.0% from $285.3 million, while diluted EPS increased to $0.52 from $0.48. Growth was overwhelmingly volume-driven and included approximately $30 million from initial distribution load-in, but gross margin fell to 36.0% from 40.5% as transportation costs, depreciation, and Arkansas startup expenses rose. Free cash flow was $134.6 million, and Trex raised its full-year sales and adjusted EBITDA outlook.

Core Q3 2026 Results

Revenue expanded much faster than profit. GAAP operating income increased about 3%, while net income was nearly unchanged, showing that lower gross margin absorbed much of the benefit from higher sales. Adjusted EBITDA grew 10%, but that also trailed the 26% increase in revenue.

Adjusted net income was $55.7 million, compared with $54.7 million a year earlier. The faster increase in per-share earnings relative to net income also reflected a lower diluted share count following repurchases.

Business and Distribution Performance

Trex said growth was led by broad volume gains, particularly in the Trex Enhance product line, with minimal benefit from pricing. Management attributed the performance to consumer demand, wood-conversion initiatives, and market-share gains rather than a meaningful improvement in the broader end market.

Approximately $30 million of revenue came from initial inventory placements with new and expanded distribution partners. On a simple basis, excluding that amount would leave about $329.5 million of sales, roughly 15.5% above the prior-year quarter; this is a calculated figure rather than a company-reported organic growth measure.

The distribution transition was completed with minimal channel disruption, according to Trex. Inventory increased at selected partners as products were placed, while inventory held by the former partner declined, leaving overall channel inventory comparable with the prior year.

Trex also continued ramping its Arkansas manufacturing facility. The company expects approximately 50% of the facility’s existing decking production capacity to be operational by year-end, although startup costs exceeded its expectations during the quarter because of mechanical issues that management said have since been resolved.

Volume Growth Outpaced Profit Growth as Gross Margin Contracted

Gross margin declined 4.5 percentage points to 36.0%, causing operating income to grow much more slowly than revenue. Operating margin was approximately 20.2%, down from about 24.7% a year earlier.

Trex identified three main sources of pressure: higher transportation-related input costs associated with diesel prices, additional depreciation from recent capacity investments, and increased Arkansas startup expenses. Arkansas costs included in cost of sales rose to $3.2 million from $1.4 million. Even after excluding those costs, adjusted gross margin was 36.9%, compared with approximately 41.0% based on the prior-year adjusted gross profit figures, indicating that the margin decline was not solely a startup-cost issue.

SG&A expense increased to $56.5 million from $45.0 million, although it remained nearly stable as a share of sales at 15.7% versus 15.8%. Excluding digital transformation costs, SG&A was $55 million, up from $43 million, primarily because of investments in personnel, capabilities, and brand-building.

Cash Flow, Balance Sheet, and Capital Allocation

Operating cash flow fell to $152.6 million from $196.9 million, but lower investment spending limited the decline in free cash flow. Capital expenditures decreased to $16.6 million from $53.9 million as construction of the Arkansas facility approached completion, while purchased intangibles declined to $1.4 million from $3.4 million.

During the quarter, Trex repurchased approximately 1.2 million shares for $55 million and repaid $83 million under its revolving credit facility. As of September 30, the company had $3.3 million of cash and $170 million outstanding on its line of credit, compared with $133.5 million at the end of 2025.

Trex expects to complete its board-authorized $150 million repurchase program by year-end, bringing total 2026 repurchases to approximately $300 million. The repurchases reduced diluted weighted-average shares to 101.8 million from 107.3 million, helping EPS grow faster than net income.

2026 Guidance

Trex raised its full-year 2026 net sales and adjusted EBITDA expectations and issued a Q4 sales range. The release did not provide the previous ranges, so the size of the increases cannot be quantified.

Management based the higher outlook on year-to-date execution, continued product demand, and confidence in its distribution and manufacturing initiatives. It nevertheless described the broader market environment as mixed.

Recent Insider Transactions

The latest 10 reported insider transactions consisted of nine stock awards and one sale. All were reported as direct holdings; the records do not by themselves indicate insiders’ views on Trex’s prospects.

Risks Investors Need to Watch

• Gross-margin recovery: Transportation-related input costs, higher depreciation, and Arkansas startup expenses reduced gross margin by 4.5 percentage points. Moderating startup costs alone may not restore the prior-year margin level.
• Arkansas execution: The facility remains on schedule to reach approximately 50% of existing decking capacity by year-end, but Q3 mechanical issues produced higher-than-expected startup costs. The pace of utilization will affect future efficiency and margins.
• Distribution normalization: About $30 million of Q3 revenue came from initial distribution load-in. Future results will depend more on underlying product sell-through once these inventory placements are completed.
• Mixed end-market conditions: Management said growth was primarily driven by Trex-specific initiatives and market-share gains rather than broad market improvement, making continued execution important if industry demand remains uneven.
• Capital allocation and leverage: Trex is pursuing substantial repurchases while carrying $170 million on its credit line and holding $3.3 million in cash. Future free cash flow and borrowing levels will determine how these capital returns affect the balance sheet.

Summary

Trex delivered 26% sales growth through higher volume, market-share initiatives, and distribution inventory placements, but gross-margin pressure kept operating and net income growth modest. Lower capital spending supported free cash flow, while the raised full-year outlook signals confidence in demand and execution. The central issues for upcoming quarters are whether margins recover as Arkansas production scales and whether underlying demand sustains growth after the initial distribution load-in ends.
