Comfort Systems USA quarterly revenue jumps 54% on data-center demand

what happened

Comfort Systems USA, a mechanical and electrical contractor, said third-quarter 2026 revenue reached $3.77 billion, more than half above the $2.45 billion booked a year earlier. Net income climbed 67.7% to $489.04 million, and diluted earnings per share rose to $13.91 from $8.25. These figures come from TradingView summaries of the company's SEC filing and press release.

Nine-month revenue rose 53.3% to $9.90 billion. Demand from data-center projects did most of the work, particularly in Texas and in modular construction. Electrical revenue grew 84.8% and mechanical revenue 42.7%. Operating cash flow came in at $1.01 billion, compared with $553.3 million a year ago.

Backlog stood at $17.81 billion, 26.7% above the end of the second quarter and 90% higher than a year earlier. Management expects robust demand through 2026 and 2027, while pointing to labor costs and occasional supply delays as execution risks.

why it matters

The data-center build-out is the main driver here, and it makes Comfort Systems a useful gauge of AI infrastructure spending. A backlog growing faster than revenue suggests contracted work extending well past the current quarter. Labor costs and equipment supply delays remain the key risks to margins.
