A superb payer that is not an income holding at this price. Comfort Systems raised its dividend three times in 2026 — $0.70, $0.80, $0.90, then $1.00 on October 22 — and FY2025 dividends were only 6.7% of free cash flow, with $981.9 million of cash against $151.4 million of debt. All three rubric checks pass. The tag stays warn because the trailing yield is 0.23%: under §1 a yield under 1% is a growth holding, not income, and the card must say so.
Key risk: The dividend is trivial against a $1,288 share price that fell from a $2,073.99 52-week high, so income buyers are buying price appreciation, not a paycheck, and the CFO transition announced alongside the Q3 results adds execution uncertainty to a record $17.81 billion backlog.
Changes if: The trailing yield reaches 1%, or free-cash-flow payout rises past 60%.
- ✓Cash-flow cover 6.7% of FY2025 free cash flow, pass (<60%). 9-month 2026 operating cash flow was $2.54bn vs $717.8m a year earlier (Q3 10-Q).
- ✓Leverage Net cash $830.5m; no borrowings on the $1.10bn revolver at Sep 30, 2026. Pass (<3x).
- ✓Growth record Dividends declared per share rose every year 2009–2025 ($0.19 → $1.95) and three more times in 2026; no cut in 10 years.
- !Income-purpose screen Trailing yield 0.23% is under 1% — §1 warn (growth holding, not income), regardless of the three passes.
What this grade doesn't say: It screens the dividend only — covered, real, compounding. It says nothing about valuation or price: a well-covered payer can still be overpriced, and its price can still fall.
