AI Brief

Q3 FY26 earnings call · Oct 23, 2026
Q3 FY26

TL;DR. Comfort Systems USA reported strong third-quarter growth, record backlog, and more than $1 billion of quarterly operating cash flow, while management expects continued growth and strong results through 2027. Near-term risks include lower year-over-year electrical margins, cost-mix pressure on sequential margins, and elevated capital spending.

Bullish
  • + Third-quarter revenue rose 54% to $3.8 billion and diluted EPS increased to $13.91 from $8.25.
  • + Backlog reached a record $17.8 billion and increased for an eighth consecutive quarter.
  • + Management expects full-year 2026 same-store revenue in the mid-40% range and mid-20% growth in 2027.
  • + The quarterly dividend was increased by $0.10 to $1.00 per share.
  • + The two August acquisitions are expected to contribute more than $100 million of annual revenue at good margins.
Bearish
  • − Electrical gross margin declined to 24.3% from 26.2% in the prior-year quarter.
  • − A higher proportion of equipment and materials dampened sequential margins.
  • − Full-year capital spending is estimated at 45% of revenue and elevated spending is expected to continue in the first half of 2027.
  • − Acquisition pricing remains high.
