Did FIX Beat Earnings? Q4 2025 Results
Comfort Systems USA delivered a blowout Q4 2025, posting diluted EPS of $9.37 against a consensus estimate of $6.73, a 39.23% beat, while revenue climbed 41.7% year-over-year to $2.65 billion, well ahead of the $2.34 billion Wall Street had expected. The results were fueled by an extraordinary surge in data center and technology infrastructure demand, which now accounts for roughly 45% of company revenue and drove gross margins to 25.5% from 23.2% a year earlier. Net income more than doubled to $330.81 million from $145.87 million in the prior-year quarter, and <a href="https://247wallst.com/investing/2026/02/19/live-comfort-systems-reports-earnings-tonight-after-65-rally/">full-year free cash flow</a> reached $1.04 billion. Perhaps the most compelling signal for investors was the record $11.94 billion backlog at year-end, roughly double the figure at the start of 2025, including a third consecutive same-store increase exceeding $1 billion in a single quarter. Management offered no specific numerical guidance for 2026 but expressed confidence that persistent demand and a strengthening project pipeline would sustain the company's momentum well into the year ahead.
