ALGM · PEAD ↓ 22

Allegro MicroSystems reported Q1 FY2026 EPS of $0.15 on 2026-07-30, missing the $0.16 consensus by $0.01 (-6.25%); year-over-year comparison is not available in current data.

Print-day reaction was -1.8% versus the prior close, a modest but directionally negative response to the EPS miss. The overnight gap to T+1 open recovered +2.0%, suggesting an initial after-hours bid that partially offset the print-day decline. Over the following two trading days the stock drifted +3.3%, a continuation that ran counter to the original negative reaction rather than confirming it. Cumulative abnormal return of -4.2% versus SPY.US over the three-day window places this in PEAD short territory despite the surface drift; the holding window runs through 2026-10-27.
