At first glance, it looks like just another institutional engineering and construction contractor specializing in plumbing, HVAC, and electrical work. And technically speaking, that's exactly what it is.
Nevertheless, the rapid explosion of artificial intelligence data centers is proving a boon for Comfort Systems USA (FIX +2.51%). Last quarter's top line of $3.27 million was up 50% year over year, reflecting the fact that nearly 60% of this company's business comes from the technology sector, with the lion's share of that business coming from the construction of new AI data centers.
Moreover, the company's backlog grew from $12.45 billion at the end of March to $14.06 billion as of the end of June. Again, data centers are the chief driver of this future growth.

If you're interested in becoming a shareholder, just think it through carefully before diving in. While it's a relatively small and relatively unknown name, at least a few investors have connected the dots. The stock's up over 140% for the past year and more than 2,000% higher for the past five years, in step with the explosion of artificial intelligence data centers.

Key Data Points
That's made the stock relatively expensive -- although not outrageously so. Shares are trading at roughly 30 times next year's expected per-share profit of $60.04, up roughly 23% from analysts' bottom-line projection for this year, en route to expected earnings of $75.46 per share in 2028.
And speaking of analysts, most of the few covering Comfort Systems USA rate its stock a strong buy with a consensus price target of $2,217.63, more than 27% above the ticker's current price.
It's certainly not the only overlooked way to plug into the artificial intelligence craze that's still going strong. But this stock's certainly worth a closer look, or a spot on your watch list.
