Comfort Systems backlog nearly doubles to $12B, driven by data center and AI infrastructure demand

Comfort Systems USA has entered 2026 with strong order momentum, supported by a record backlog approaching $12 billion at year-end 2025, nearly double the prior year. The surge reflects robust bookings, particularly in data centres, with technology-related work accounting for 45% of 2025 revenue, up from 33% previously. Fourth-quarter 2025 revenues rose 42% year-over-year to $2.65 billion, whilst earnings per share more than doubled. The backlog's extended duration, driven by larger and more complex projects, provides multi-year revenue visibility through 2027 and beyond. The company is expanding modular capacity and investing in workforce and acquisitions to support future demand. Key competitors include EMCOR Group and Quanta Services, which compete across data centre and infrastructure projects.

The company has delivered 1,500% gains over five years. The firm reported a record backlog of nearly $12 billion in February, roughly double from the start of the year and up 27.3% quarter-over-quarter. Fourth-quarter revenue jumped 41.7% year-over-year whilst net income more than doubled. The company maintains a 10-year revenue compound annual growth rate of 21.3%.

Comfort Systems scales modular capacity to 4M sq ft to capture data centre growth

Comfort Systems USA has raised its modular construction capacity to approximately 3 million square feet and plans to expand to nearly 4 million square feet by the end of 2026. The move comes as the company reported strong 2025 results, with revenue rising 29.5% year over year to $9.1 billion and earnings per share surging 97.8% to $28.88. The expansion responds to growing demand for prefabricated solutions, particularly in data centre projects driven by AI and cloud computing. Modular construction offers faster project timelines, improved labour productivity and enhanced quality control whilst addressing skilled labour constraints. The strategy positions Comfort Systems competitively against firms like AECOM and Jacobs Solutions, giving it advantages in execution speed and modular deployment whilst strengthening margins through its integrated design-build model.

2 cash-producing stocks for long-term investors and 1 to avoid

Comfort Systems, a mechanical and electrical contracting services provider, has raised its free cash flow margin by 6.1 percentage points over five years to 11.4%. The company's backlog has grown 47.6% on average over the past two years, indicating strong demand exceeding supply. Lam Research, a semiconductor wafer fabrication equipment provider, posted a 30.2% trailing 12-month free cash flow margin. The company achieved 19.8% annual revenue growth over the past two years whilst improving capital efficiency. Meanwhile, Kimberly-Clark faces challenges despite its 10% free cash flow margin. The household products company has seen disappointing organic revenue growth and its free cash flow margin declined by five percentage points over the past year. Analysts expect just 2.1% sales growth next year.
