Comfort Systems USA Stock Jumps After Profit More Than Doubles On Data Center Demand

24 April 2026

HOUSTON, April 23, 2026, 16:56 CDT

First-quarter earnings at Comfort Systems USA jumped to $370.4 million, a sharp rise from $169.3 million reported in the same period last year.
Revenue jumped 56.5% to $2.87 billion, with a boost from tech-sector projects—data centers stood out.
The backlog climbed to $12.45 billion. The board also bumped the quarterly dividend up to 80 cents per share.

Comfort Systems USA Inc. saw its first-quarter profit surge, with technology and data-center projects driving both revenue and backlog sharply higher—pushing shares up after hours. The Houston contractor posted net income of $370.4 million, or $10.51 per diluted share, a jump from $169.3 million, or $4.75 per share, in the same quarter last year.

The report has fresh weight as investors look for evidence the data-center surge is still boosting firms beyond just chipmakers and server suppliers—specifically the contractors handling the cooling, wiring, and outfitting work. Comfort Systems posted a 56.5% jump in first-quarter revenue, reaching $2.87 billion, and highlighted “especially strong” demand from the tech sector, with data centers standing out in its latest filing.

Backlog climbed to $12.45 billion as of March 31, up from $11.94 billion at the end of last year and $6.89 billion a year ago. The company noted that backlog signals revenue trends for the coming six to 12 months, but doesn’t capture the full picture beyond that window.

The stock was recently seen at $1,773.91, a gain of $52.18 from its previous finish, after hitting an intraday peak of $1,905. Market data pegged the company’s valuation around $62.7 billion.

Comfort Systems’ March-quarter earnings easily topped the mean LSEG estimate of $6.80 a share, according to figures posted on the company’s investor page. That same site put the average analyst recommendation at 1.67 on the scale from sell to strong buy.

Chief Executive Brian Lane noted “robust ongoing demand” and “strong pipelines,” highlighting that the backlog increased despite the company pushing through projects more quickly. Lane called out a 51% jump in organic revenue—growth generated by existing operations, not acquisitions. Comfort Systems USA

Growth leaned heavily on tech, but gains spread across the board. Mechanical segment revenue hit $2.06 billion, up 47%, while the electrical side soared 87.5% to $804.7 million. Tech sector work in Texas, Indiana, and North Carolina fueled much of the improvement, according to Comfort Systems.

Margins stretched out, too. Gross profit came in at $754.4 million, up from $403.4 million. Gross margin hit 26.3%, an improvement over last year’s 22.0%, with the filing pointing to better execution and positive turns in a few late-stage projects—change orders among them.

Operating cash inflow came in at $388.8 million for the company, swinging from an $88.0 million outflow the same period last year. Free cash flow totaled $242.2 million—last year’s figure was negative $109.1 million for the quarter, after routine capital spending and asset-sale proceeds.

Comfort Systems bumped its quarterly dividend to $0.80 per share, a 10-cent increase over its last payout. Shareholders on record as of May 15 will get the dividend, set for distribution on May 26.

EMCOR Group calls the electrical and mechanical construction services space “highly fragmented” in its latest annual filing, pointing to Comfort Systems and APi Group as bigger rivals. Customers, the company notes, size up providers on skilled labor, technical know-how, safety, cost management, and niche market experience. SEC

Still, backlog doesn’t translate directly to money on hand. Comfort Systems flagged in its filing that contracted jobs can shift or even get scrapped, warning investors not to count backlog as a surefire indicator of future earnings. The company also pointed to rising labor expenses, thanks to more employees and higher wages.

Comfort Systems USA has scheduled its conference call for Friday at 10:00 a.m. Central Time to go over the results. Investors are expected to question management about the sustainability of data-center demand translating into lasting margins, especially after a quarter that raised expectations.
