Comfort Systems USA IncSurge in demand for data center cooling and power infrastructure drives revenue growth.

Comfort Systems USA has returned more than 2,000% over the past five years, easily beating Nvidia's return of just under 1,000%. The HVAC and mechanical contractor benefited from surging demand for data center cooling and power infrastructure, with over half of its revenue now coming from tech and data center projects. In the second quarter, Comfort Systems reported revenue of $3.26 billion, up 50.3% year over year, and earnings per share of $12.53, up 91.9%, while trimming total debt to $54.1 million from $145 million a year earlier. The company now has a market capitalization of $59 billion and a trailing price-to-earnings ratio of nearly 50, higher than competitors Emcor Group, IES Holdings, and Sterling Infrastructure. Analysts note that its physical scaling limits and high valuation make it unlikely to repeat such outsized gains, though it maintains a backlog of more than $14 billion and has increased its dividend for 14 consecutive years.
