Comfort Systems USA stock follows 2026 earnings surge and record backlog

Comfort Systems USA reported on Thursday, October 22, 2026, that third-quarter revenue and profit rose sharply from a year earlier. The company said demand remained strong across its mechanical, electrical, modular and plumbing building-services operations. Its shares later traded at 1,037.00 euros on Lang & Schwarz at 13:05 CET on Friday, November 13, 2026.

Revenue for the quarter ended September 30 reached 3.77 billion US dollars, compared with 2.45 billion US dollars in the third quarter of 2025. Net income increased to 489.0 million US dollars from 291.6 million US dollars, while diluted earnings per share rose to 13.91 US dollars from 8.25 US dollars.

The operating figures also showed stronger profitability. Operating income was 624.6 million US dollars, equal to a 16.6 percent margin, up from 15.5 percent a year earlier. Adjusted EBITDA rose to 667.9 million US dollars, or 17.7 percent of revenue, compared with 413.9 million US dollars and a 16.9 percent margin in the prior-year quarter.

Backlog supports 2027 outlook

Backlog stood at 17.81 billion US dollars on September 30, up from 14.06 billion US dollars at the end of June and 9.38 billion US dollars a year earlier. On a same-store basis, backlog reached 17.39 billion US dollars, also well above the prior-year level.

Chief Executive Officer Brian Lane attributed the performance to ongoing demand and execution by the company's teams. He said Comfort Systems generated more than 1 billion US dollars of operating cash flow in the quarter. Management also said the company was positioned to grow organically through year-end and in 2027 while maintaining high profitability and solid cash flow.

Cash from operating activities totaled 1.01 billion US dollars in the quarter, compared with 553.3 million US dollars in the year-earlier period. Free cash flow was 805.6 million US dollars, up from 519.0 million US dollars. For the first nine months, revenue reached 9.90 billion US dollars and net income 1.30 billion US dollars, compared with 6.46 billion US dollars and 691.8 million US dollars, respectively, in 2025.

The company also declared a quarterly dividend of 1.00 US dollar per share, an increase of 0.10 US dollars from the previous payout. The dividend is payable on November 23, 2026, to shareholders of record on November 12.

Market weighs growth and expectations

A Globe and Mail report said the quarterly revenue and adjusted EBITDA figures exceeded analyst estimates. The report also said the shares traded down 7.6 percent to 1,186 US dollars immediately after the results. That historical reaction highlights the market's high expectations even as the operating indicators remained strong.

Comfort Systems is scheduled to transition its finance leadership after filing the 2026 annual report. Chief Financial Officer William George plans to retire after the filing, and Julie Shaeff, currently senior vice president and chief accounting officer, is set to succeed him under the company's succession plan.

Investors will next focus on execution against the record backlog, labor and supply-chain conditions, and the CFO transition after the annual report. The company's broader market environment remains relevant for valuation-sensitive industrial stocks.
