ENTG · PEAD → 0

Entegris reported Q3 2026 EPS of $1.23 on 2026-10-29, beating the $1.04 consensus by $0.19 (+18.3%).

Print-day reaction was a muted +0.4% versus the prior close of $159.32, a notably compressed move given the magnitude of the EPS beat. The overnight gap into T+1 open was a sharp reversal of -4.7%, wiping out the initial gain and signalling immediate post-market selling pressure. Over the subsequent two trading days the stock drifted a further -1.1%, with no stabilisation — compounding rather than recovering the overnight gap. Cumulative abnormal return of -1.8% versus SPY.US lands inside the ±3% neutral band, yielding a PEAD verdict of none with zero conviction; no directional read is established through the holding window ending 2027-01-26.
