ROGERS MARK N 4

What Happened Mark N. Rogers, Executive Vice President and General Counsel of Amkor Technology (AMKR), exercised options and sold shares in a series of transactions on Feb 16–17, 2026.

Separately, 1,856 restricted stock units (RSUs) vested on Feb 16; 796 of those vested shares were withheld to satisfy tax withholding obligations (value of withheld shares: $47.48 × 796 = $37,794).

Context

• The sequence (exercise of options at $7.40 followed immediately by an open‑market sale at $46.92) is a common pattern where exercised shares are sold soon after vest/exercise (often to cover exercise cost and taxes). The sale was executed under a pre‑established 10b5‑1 plan, which indicates the trades were pre‑planned rather than ad hoc.
