Revenue and Growth Highlights#

In the first quarter of 2026, Comfort Systems reported revenues of $2.87 billion, significantly surpassing the consensus estimate of $2.40 billion. This marks a remarkable 57% increase in revenue year-over-year, driven by a 52% increase in organic growth and contributions from acquisitions.

The technology sector saw a staggering 139% growth year-over-year, making up about 56% of the company's sales during the quarter, primarily from data center projects. The adjusted earnings before interest, taxes, depreciation, and amortization (EBITDA) reached $524 million, exceeding the expected $355 million, thanks to better-than-expected profit margins in both business segments.

Profitability and Backlog Growth#

The company's profitability was positively impacted by approximately $43 million from unusual closeout and change order benefits, which added nearly a dollar to earnings per share. Additionally, Comfort Systems' total backlog grew by 81% compared to the previous year, with the Mechanical segment increasing by 84% and the Electrical segment by 70%.
