Comfort Systems USA is a national HVAC and electrical contractor, and the demand environment its filings describe as historic through mid-2026 is the company's central strategic variable. The share price has roughly quadrupled over twelve months, and the market is now paying for one question: whether a multi-billion backlog can convert into earnings without breaking the margin model. The scale of the re-rating is the defining fact of the last year for this stock.
Second-quarter revenue grew 50.3 percent to 3.27 billion, with the electrical segment carrying the mix as data center work in Texas and the new R.C. Hunt Electric acquisition added volumes. That combination of organic strength and bought scale is the underlying driver, and the numbers reflect both moving at once. Operating cash flow of 1.14 billion in the quarter, against a far smaller print a year earlier, shows the working capital machine at full stretch.
Net income of 441.6 million, or 12.53 per share, plus a dividend increase, sets up the forward question. Can same-store backlog growth that now feeds mostly one end market stay broad enough to protect a multiple built on this run?
