COHR · PEAD ↑ 81

Coherent reported Q4 FY2026 EPS of $1.47 on 2026-08-12, beating the $1.43 consensus by $0.04 (+2.8%).

Print-day reaction was +8.2% versus the prior close, a sharp gap-up open that held through the session. The overnight gap to the T+1 open gave back 3.0%, signalling meaningful after-hours profit-taking against the initial surge. Over the following two trading days (T+1 through T+3), the stock drifted +7.3%, recovering the overnight fade and then some, confirming demand absorbed the near-term supply. Cumulative abnormal return of +6.6% versus SPY.US places this firmly in PEAD long territory — drift confirms and extends the initial reaction; the documented pattern holds through 2026-11-09.
