Rutten Guillaume Marie Jean 4

What Happened Guillaume Rutten, a director of Amkor Technology (AMKR), had 8,692 restricted stock units (RSUs) convert into common shares on 2026-03-31 (listed as an exercise/conversion of a derivative at $0). The same 8,692 shares are also listed as a disposition (derivative) on 2026-03-31 at $0 in the filing. On 2026-04-01 he was recorded as acquiring 482 shares via a director RSU award (grant) at $0. These entries reflect compensation vesting/award activity rather than an open-market purchase.

Key Details

• Transaction dates and prices:
  • 2026-03-31: Conversion/exercise (code M) — 8,692 shares acquired at $0; same date shows 8,692 shares disposed (derivative) at $0.
  • 2026-04-01: Grant/award (code A) — 482 shares acquired at $0.
• Shares owned after transaction: Not specified in the provided filing excerpt.
• Footnotes:
  • F1: The 8,692 conversion aligns with a Feb 20, 2025 grant of 43,459 time-vested RSUs that vest in five equal quarterly installments (one installment vested on 3/31/2026).
  • F2: The 482 shares relate to Director RSUs granted on 4/1/2025 that vest on the earlier of the first anniversary or the first annual meeting following the grant; awarded for director service.
• Timeliness: Form 4 was filed 2026-04-02 for transactions on 3/31 and 4/1, which appears timely (Form 4 is generally due within two business days).

Context These entries are routine director compensation events (vesting/conversion of RSUs and a director RSU award). The $0 exercise price indicates stock granted/vested rather than a cash purchase. The filing lists both acquisition and disposition of the 8,692 shares on 3/31; when conversions are followed by same-day dispositions, that often reflects tax withholding or immediate sale, but the filing does not specify the reason. Such awards are common and do not by themselves indicate the director’s market view.
