Comfort Systems backlog hits record $17.8B as revenue jumps 54% and CFO retires

Comfort Systems (NYSE:FIX) reported third-quarter diluted net income of $13.91 per share on October 23, 2026, as revenue rose 54% year over year. Demand from technology and industrial customers drove the results. The mechanical and electrical contractor's backlog reached a record $17.8 billion. Clients are booking large projects early to secure contractor capacity, which extends timelines by 18 to 24 months and locks in revenue into 2028. The company is expanding modular manufacturing capacity to 6 million square feet, serving data centre customers including a frontier lab and colocation providers. Chief financial officer Bill George is retiring after 30 years. Chief accounting officer Julie S. Shaeff will succeed him. Management expects continued growth through 2027, with strong gross profit margins.

AI data centre suppliers fall despite blowout quarters, shedding over $300B since October

Shares of AI data centre suppliers fell for a second day despite strong results. Bloom Energy said sales rose 138% last quarter and raised its full-year growth outlook to roughly 122%. Comfort Systems said its backlog nearly doubled to $17.8 billion. Since the S&P 500's October 6 record close, companies building and equipping AI data centres are down a median 23%, according to Yahoo Finance calculations. Nvidia is off 11%, while the Big Tech companies funding the build-out are down 5%. A dozen of the biggest builders and power names have lost more than $300 billion in market value. Bloom's cash flow turned negative in the quarter, and its margins lag sales growth. The next test comes Wednesday, when Microsoft, Alphabet, and Vertiv report, followed by Amazon on Thursday.
