Fun facts about TREX CO INC

Quirks, history, and lore behind TREX — the kind of stuff that makes a stock memorable.

1
The Basics
U.S. building products company · mid-cap · listed on the NYSE · headquartered in Virginia.
2
The Numbers
Annual revenue in the range of $1 billion, with margins that make traditional lumber companies deeply jealous — gross margins above 40% in good years.
3
The History
Founded in the 1990s, it was a pioneer in turning recycled plastic and wood fiber into a product most people assumed could only come from a tree.
4
The Secret
Its core product never needs staining, sealing, or painting — a major selling point over real wood, which rots, splinters, and demands weekend-ruining maintenance.
5
The Lore
The company diverted billions of pounds of plastic film and reclaimed wood from landfills to make its products — so your backyard upgrade is technically a recycling project.
6
The Giveaway
It is the dominant brand in composite decking — if an American has a beautiful low-maintenance deck out back, there's a very good chance it came from this company.

AI Insight: TREX Financial Trends

Q4 2025 operating income collapsed to $4M — the weakest quarter in the dataset — but Q1 2026 rebounded sharply to $84M, tracking Q1 2025 closely.

• Revenue has been range-bound year-over-year: Q1 2026 at $343M versus Q1 2025 at $340M, suggesting flat top-line growth.

• Operating income in Q4 2025 fell to just $4M versus $32M in Q4 2024, a steep 88% year-over-year deterioration in the seasonally slow quarter.

• Equity has grown from $895M in Q2 2024 to $996M in Q1 2026, reflecting retained earnings accumulation over the period.

• Operating cash flow swung from -$154M in Q1 2025 to -$118M in Q1 2026, a modest improvement but still a significant seasonal cash outflow.

⚠ Q4 2025 net income of $2M versus $10M in Q4 2024 signals worsening profitability in off-peak quarters — a trend worth monitoring.

⚠ Operating margin in Q2 2025 was ~26% versus ~31% in Q2 2024 — peak-season margin compression despite higher revenue.

⚠ Total debt is absent from all periods; if leverage is being deployed quietly, it could alter the equity-growth narrative.

AI Insight: TREX Ratio Trends

Q1 2026 operating margin of 24.3% nearly matches peak Q2 2025 levels, but Q4 2025's 2.2% collapse drags TTM profitability to 22.1%.

• Operating margin recovered to 24.3% in Q1 2026 after crashing to 2.2% in Q4 2025, suggesting Q4 was a one-off trough.

• ROIC improved to 33.5% in Q1 2026 from 1.4% in Q4 2025, though still below Q2 2025's 41.4% peak.

• TTM OpMargin of 22.1% and ROIC of 26.1% lag Q1 2026 standalone figures, entirely due to Q4 2025 drag.

• Year-over-year, Q1 2026 OpMargin of 24.3% exceeds Q1 2025's 24.0%, signaling modest underlying improvement.

⚠ Q4 2025 OpMargin collapsed to 2.2% from 24.7% in Q3 2025 — magnitude of drop warrants scrutiny for recurrence.

⚠ ROIC has not returned to Q2 2024's 52.2% peak; sustained recovery above 40% remains unconfirmed.

⚠ D/E data absent across all periods — leverage position and capital structure changes cannot be assessed.
