1 Hot Industrial Stock Riding the AI Infrastructure Boom
Yahoo Finance ·
Mechanical and electrical contracting services company Comfort Systems USA ( FIX 7.95% ) is a major winner from surging artificial intelligence (AI) data center investment. A high proportion of a data center's cost is in mechanical, electrical, and plumbing (MEP) systems, not least to ensure adequate cooling for heat-intensive IT racks. That's led to booming demand for the company's services and an incredible 1,160% return for investors over the last three years. The increase comes down to surging orders driving backlog and revenue growth, along with margin expansion. The growth in its backlog (shown below) leads to highly predictable revenue growth in the future. Data source: Comfort Systems presentations. Chart by the author. Turning to the question of margin expansion, it comes from a combination of being able to selectively bid on complex and higher-margin AI data center projects, a natural leverage opportunity, as the marginal increase in revenue isn't accompanied by a significant increase in overhead costs, and the increase in its modular revenue, which represented 17% of its revenue in the first quarter of 2026. Modular systems are manufactured at Comfort Systems locations (rather than onsite by tradespeople) and then transported and fitted onsite. It's a solution that confers several benefits for Comfort Systems and facility owners, such as optimizing MEP labor, improving quality control, and ensuring no disruption to the critical path of construction.
