FIX Q1 2026: Revenue Doubles, Record Backlog as Data-Center Demand Accelerates
Comfort Systems USA's Q1 2026 results show data-center construction demand is still accelerating, driving both revenue growth and margin expansion. Revenue rose 56% YoY to $2.87 billion, beating estimates by 20%, while gross margin reached a record 26.3%. Backlog climbed to $12.5 billion, supporting management's mid- to high-20% organic growth outlook. The initial market reaction was negative — a 3.5% abnormal decline — likely reflecting concerns over sustainability, a one-time $43 million change-order benefit, and surging capital expenditures of $147 million. The stock subsequently drifted 5.9% higher. With a bullish score of 85 and maintained guidance, the fundamental picture is strong, but labor constraints, capex efficiency, and acquisition integration are key execution risks.

Methodology
Reported and consensus figures come from FN2's earnings event records. Market reaction and volume are calculated from daily adjusted bars around the event; abnormal move subtracts the SPY move over the same window.
Analyst target low, average, and high values are derived at request time from each named analyst's latest persisted FMP target. The current-price marker comes from FN2's persisted market snapshot. They are sell-side estimates, not an FN2 valuation or recommendation.
Transcript intelligence is a structured synthesis of the current and prior earnings-call analyses. Missing values stay missing and are never estimated.
