AVAV · PEAD ↑ 18

AeroVironment reported Q1 FY2027 EPS of $0.59 on 2026-09-09, beating the $0.22 consensus by $0.37 (+168.2%).

Print-day reaction was −5.4% versus the prior close, an initial sell-the-news drop despite the substantial EPS beat. The overnight gap recovered sharply, adding +4.2% from the T+0 close to the T+1 open, signalling that after-hours buyers absorbed the print-day weakness. Days 1–3 drift continued the recovery, adding another +4.3% from the T+1 close through the T+3 close, a sustained reversal of the opening-day fade. Cumulative abnormal return of +3.8% versus SPY.US clears the +3% threshold for a PEAD long read — drift decisively reversed the initial negative reaction; holding window runs through 2026-12-07.
