FIX · PEAD ↓ 56

Comfort Systems USA reported Q3 2026 EPS of $13.91 on 2026-10-22, beating the $12.71 consensus by $1.20 (+9.4%).

Print-day reaction was –8.7% versus the prior close, a sharp sell-the-news flush despite the sizable EPS beat. The overnight gap to the T+1 open extended losses by another –5.3%, signalling no after-hours stabilisation. Over the following two trading sessions the price drifted +11.0% off the T+1 open, a partial recovery but insufficient to reclaim pre-earnings levels. Cumulative abnormal return of –7.6% versus SPY.US keeps this firmly in PEAD short territory; the documented drift pattern holds through 2027-01-19.
