Amkor (AMKR) Director Guillaume Rutten Sells 10,000 Shares
What Happened
Director Guillaume Rutten converted 13,920 derivative awards (time‑vested RSUs) into common shares on Feb 16, 2026 (no exercise price). He then sold 10,000 of those shares in an open‑market transaction on Feb 17, 2026 for a weighted average price of $45.89, generating about $458,900. Net from these transactions, 3,920 shares remained from the conversion (absent information on prior holdings).
Key Details
- Transaction dates: Feb 16, 2026 (conversion of 13,920 RSUs into common stock), Feb 17, 2026 (sale of 10,000 shares).
- Sale price: weighted average $45.89 per share; price range reported $44.33–$46.92. Total proceeds ≈ $458,900.
- Nature of derivative: RSUs granted Feb 16, 2023 that vest in four equal annual installments beginning Feb 16, 2024 (footnote F3). Conversion recorded with $0 exercise price (typical for RSUs).
- Plan/authorization: the sale was executed under a Rule 10b5‑1 trading plan adopted by the reporting person on June 6, 2025 (footnote F1).
- Shares owned after transaction: the filing shows a net increase of 3,920 shares from this conversion minus sale; the reporting person’s total holdings after the filing are not disclosed in the supplied details.
- Timeliness: Form 4 filed Feb 18, 2026 for transactions on Feb 16–17, 2026 — appears timely (Form 4 is due within two business days).
Context
- These conversions were RSU vesting events (not option exercises requiring cash). Part of the shares were sold under a prearranged 10b5‑1 plan, which is a routine way insiders monetize shares on a schedule and does not necessarily reflect a change in view about the company.
- For retail investors, purchases typically signal stronger insider conviction than scheduled sales; this filing mainly documents routine vesting and a planned sale.
