Comfort Systems USA INC (NYSE:FIX) reported an insider sale this week after a year of outsized share gains. According to an SEC Form 4 filing, President and Chief Executive Officer Brian E. Lane sold 9,365 shares of company stock on February 25, 2026. The reported average sale price was $1,453.1168 per share, producing a total transaction value of $13,608,438.
Following the disposition, Lane is shown on the filing as directly holding 171,523 shares of Comfort Systems USA INC. The Form 4 was executed by Rachel R. Eslicker, Attorney-in-Fact, and signed on February 26, 2026, according to the disclosure in the filing.
The sale comes amid a dramatic run for the stock. Over the past 12 months the shares returned 285% and are trading in the vicinity of their 52-week high of $1,500. Market valuation metrics included in public data show the stock trading at a price-to-earnings ratio of 49.56. An InvestingPro analysis cited in the filing materials indicates the company is currently overvalued relative to its Fair Value.
Comfort Systems also released quarterly financial results that may have factored into recent market activity. For the fourth quarter of 2025 the company reported earnings per share of $9.37, exceeding consensus expectations of $6.73. Revenue for the period came in at $2.65 billion, above the forecasted $2.33 billion. Those figures, presented in the company’s earnings disclosure, outperformed analyst estimates and drew attention from market participants.
Responding to the stronger-than-expected results, DA Davidson adjusted its valuation view on the shares. The firm raised its price target for Comfort Systems USA from $1,200 to $1,800 while keeping a Buy rating in place, citing the company’s reported earnings strength, cash flow, and bookings as rationale for the higher target.
Investors and analysts will be able to review the SEC filing for the precise details of Lane’s sale, including the reported price and remaining holdings. The company’s recent earnings outperformance and the analyst price-target revision sit alongside third-party commentary on valuation, creating a mixed factual picture in which strong operating results coexist with metrics that some services currently judge as indicating overvaluation.
