ARM · PEAD ↓ 61

ARM Holdings reported Q1 FY2027 EPS of $0.20 on 2026-07-29 (after market close), beating the $0.18 consensus by $0.02 (+11.1%); prior-year comparable EPS was not available in the data feed.

Print-day reaction was −8.1% versus the prior close, a sharp sell-the-news move despite the EPS beat. The overnight gap to T+1 open was a striking +14.7%, suggesting buyers stepped in aggressively in after-hours and pre-market trade. Day 1-to-3 drift then gave back that gap enthusiasm, declining −1.0% from T+1 close to T+3 close, confirming the initial negative reaction rather than sustaining the overnight bounce. Cumulative abnormal return of −4.6% versus SPY.US puts this firmly in PEAD short territory; per the documented drift pattern, the read runs through 2026-10-26.
