Comfort Systems USA Achieves 30% Revenue Growth and 14.4% Operating Margin
Comfort Systems USA recorded FY2025 revenue of $9.1 billion, a 30% year-over-year increase, with operating margin rising to 14.4% from 10.7% and EPS reaching $28.88. Free cash flow exceeded $1 billion and the company ended the year with net cash backing a nearly $12 billion backlog.
1. FY2025 Financial Highlights
Comfort Systems USA generated $9.1 billion in revenue for fiscal 2025, up nearly 30% from the prior year, with fourth-quarter sales exceeding $2.65 billion. Diluted EPS reached $28.88, reflecting genuine operational strength, while trailing and forward P/E ratios stood at 42.83 and 33.44 respectively.
2. Margin Expansion Drivers
Operating margin expanded to 14.4% from 10.7% a year earlier, and net margin rose to 11.2%, driven by disciplined bidding, stronger execution, operating leverage, and a favorable project mix focused on data centers, electrification, industrial reshoring, and infrastructure upgrades.
3. Cash Flow and Balance Sheet Strength
Free cash flow topped $1 billion on approximately $1.19 billion of operating cash flow, and the company closed the year with nearly $1 billion in cash against modest debt. The net cash position underpins ongoing acquisitions, dividend increases, share buybacks, and organic expansion.
4. Backlog Growth and Future Outlook
Backlog nearly doubled to $12 billion year-over-year, with strong same-store growth providing visibility into 2026. Key uncertainties include fixed-price contract execution risk, capital spending cyclicality, labor constraints, and the durability of mid-teens margins.
