ACLS · PEAD ↑ 80

Axcelis Technologies reported Q3 2026 EPS of $1.09 on 2026-11-05, beating the $0.90 consensus by $0.19 (+21.1%).

Print-day reaction was −2.3% versus the prior close, as the market initially faded the beat on the open. The overnight gap to the T+1 open reversed that weakness sharply, adding +10.0% and signalling a decisive after-hours reassessment. Over the following two trading days price continued to drift higher by +7.6%, sustaining the reversal with no meaningful give-back. Cumulative abnormal return of +18.1% versus SPY.US — which itself fell −2.2% over the same window — firmly places this in PEAD long territory; the documented drift pattern holds through 2027-02-02.
