[Comfort Systems USA](https://www.bullished.co/tag/fix/), which installs and maintains heating, cooling, plumbing and electrical systems in commercial and industrial buildings, grew third-quarter revenue 53.7% to [$3.77 billion](https://www.sec.gov/Archives/edgar/data/0001035983/000110465926118159/fix-20260930x10q.htm?ref=bullished.co), according to its 10-Q. Gross margin stayed at 24.8%, the same as a year earlier, and a larger slice of revenue came from revisions to estimates on work begun in earlier periods.

## Flat margin on a much bigger base

Gross profit rose to $934.5 million in the third quarter, up 53.7% in step with revenue, so the percentage did not move. Management credited a 46.3% rise in same-store revenue and better execution at numerous locations. A $15.5 million bankruptcy-related revenue recognition in 2025 did not repeat.

For the first nine months, gross margin rose to 25.6% from 23.6%. The company points to favorable developments on projects nearing completion in the first quarter, including change orders of about $43.1 million, and to better results in its mechanical segment.

Net income climbed to $489.0 million, or $13.91 per diluted share, from $291.6 million, or $8.25, in the [earnings release](https://www.sec.gov/Archives/edgar/data/0001035983/000110465926118156/fix-ex99d1.htm?ref=bullished.co). Selling and administrative costs fell to 8.3% of revenue from 9.4%.

## Estimate revisions add more to revenue

Comfort Systems books revenue as work progresses, so changes in estimates on jobs already underway flow straight into current results. Those revisions added 4.5% to third-quarter revenue, against 4.0% a year earlier. Over nine months they added 6.6%, against 4.6%.

Billed receivables reached $3.84 billion at September 30, from $2.58 billion at year-end. The [prior quarter's filing](https://www.sec.gov/Archives/edgar/data/0001035983/000110465926086258/fix-20260630x10q.htm?ref=bullished.co) showed $3.28 billion at June 30.

Technology customers, mainly data centers, were 60.8% of third-quarter revenue, against 45.8% a year ago. Backlog reached $17.81 billion, up 26.7% from June 30 and 90.0% from a year earlier. The company says backlog speaks only to revenue direction over the next six to 12 months.

## Buybacks surge, CFO to retire

Share repurchases totaled $340.9 million in the third quarter, up from $5.7 million in the second. For the nine months the company bought 0.2 million shares at an average $1,643.85\. The stock closed at $1,279.37 on Thursday, for a market value of $49.3 billion.

Cash from operations was $2.54 billion for nine months, against $717.8 million a year earlier. The company had no borrowings on its revolver and $1.01 billion of credit available.

Separately, an [8-K](https://www.sec.gov/Archives/edgar/data/0001035983/000110465926118149/tm2628079d1%5F8k.htm?ref=bullished.co) says CFO William George will retire after the 2026 annual report is filed. Chief Accounting Officer Julie Shaeff will succeed him.

The company hosts its conference call Friday at 10:00 a.m. Central Time, and Shaeff becomes CFO once the 2026 annual report is filed.
