The narrative around American reshoring has been loud for years. The actual revenue has been quieter – until now. In 2026, the construction of domestic semiconductor fabs, EV battery gigafactories, and advanced manufacturing campuses is no longer a political talking point. It is a capital expenditure supercycle generating billions in contract work. And one company is embedded in nearly every major project: Comfort Systems USA (FIX).
The Market Temperature
The CHIPS Act and Inflation Reduction Act together allocated over $400 billion in domestic industrial investment. That spending is now hitting its most intensive construction phase. Electrical, mechanical, and HVAC systems – the unglamorous backbone of every fab and factory – are in extraordinary demand. The companies that install and service those systems are experiencing a once-in-a-generation workload surge.
What Comfort Systems Actually Does
Comfort Systems provides mechanical, electrical, and plumbing installation and service across commercial and industrial construction. Its client list reads like a map of the reshoring boom: semiconductor manufacturers, data center developers, aerospace facilities, and pharmaceutical production sites.
The company reported record revenue of approximately $6.8 billion in fiscal 2025, with backlog growing to nearly $6.2 billion – a figure that effectively pre-funds the next 18 months of operations. Operating margins have expanded to roughly 11%, well above the industry average for mechanical contractors.
Strategic Insight
What separates FIX from a generic construction play is its service and maintenance revenue, which now accounts for over 35% of total income. This recurring stream provides earnings stability that pure-play contractors cannot match. As newly built facilities require long-term mechanical servicing, that percentage is likely to grow.
- Backlog-to-revenue ratio suggests strong forward visibility through late 2027
- Acquisitive growth strategy has added regional density without diluting margins
- Exposure to data center construction provides an additional AI-era tailwind
Risks Worth Noting
Labor shortages in skilled trades remain a persistent constraint. Project delays tied to permitting or supply chain disruptions could push backlog conversion timelines. The stock has already re-rated meaningfully from its 2023 lows, so entry valuation deserves careful attention.
The Takeaway
While most investors chased the software layer of the AI and reshoring trade, Comfort Systems has been quietly installing the physical infrastructure that makes it all possible. The numbers suggest the market is beginning to catch on – but the earnings trajectory may still have further to run.
