IFCN.SW · PEAD ↑ 10

INFICON reported Q3 2026 EPS of 1.94 on 2026-10-27, beating the 1.02 consensus by 0.92 (+90.2%).

Print-day reaction was +8.4% versus the prior close, a sharp gap-and-hold on the earnings beat. The overnight gap to the T+1 open added a further +0.7%, with no after-hours fade. Over days 1–3, however, the stock drifted –6.6%, giving back a meaningful portion of the initial surge. Cumulative abnormal return of +3.0% versus SPY.US clears the long threshold on a narrow margin; per the documented PEAD pattern, the read holds through 2027-01-22.
