IRDM · PEAD ↑ 16

Iridium reported Q3 2026 EPS of $1.0934 on 2026-10-22, beating the $0.29 consensus by $0.8034 (+277.0%), with prior-year comparable not yet in our feed.

Print-day reaction was −1.0% versus the prior close, an initial fade despite the large EPS beat, as the stock slipped from $44.25 to $43.79. The overnight gap to the T+1 open was a negligible +0.05%, indicating no meaningful after-hours directional conviction. Over the following two trading days (T+1 through T+3), IRDM drifted +2.8%, decisively reversing the print-day dip and closing at $45.65. Cumulative abnormal return of +3.6% versus SPY.US clears the long threshold; per the documented PEAD pattern, the read is held through 2027-01-19.
