Amkor (AMKR) Director Rutten Converts 172,329 RSUs to Shares

What Happened

  • Director Rutten Guillaume Marie Jean reported the conversion/exercise of time‑vested RSUs on February 20, 2026. The filing shows acquisitions of 112,941 and 59,388 shares (total 172,329) at $0.00 and matching disposals of the same amounts (also reported at $0.00). These entries reflect RSU vesting/conversion rather than a cash purchase price.

Key Details

  • Transaction date: 2026-02-20. Form 4 filed: 2026-02-24 (appears timely — within the 2 business‑day reporting window).
  • Reported amounts: 112,941 shares (F1) and 59,388 shares (F2) acquired and concurrently reported as disposed; total = 172,329 shares.
  • Reported price/value: $0.00 for both acquisition and disposition lines (typical for RSU conversions).
  • Shares owned after transaction: not specified in the provided filing details.
  • Footnotes: F1 = RSUs from Feb 20, 2024 grant (vest schedule: 40%/40%/20% over 3 years). F2 = RSUs from Feb 20, 2025 grant (vests in three equal annual installments).
  • Transaction code: M = exercise or conversion of derivative securities (here, RSUs converting to common stock).
  • No sale price or proceeds reported in the filing, and the filing does not state the reason for the reported disposals.

Context

  • These entries reflect RSUs vesting and being converted into common shares (reported at $0 because no cash exercise price was paid). The filing shows the same number of derivative shares were reported as disposed, but it does not disclose sale price, proceeds, or the nature of the disposition (e.g., open‑market sale, broker transfer, or tax withholding). For retail investors, RSU vesting/conversion is typically routine compensation-related activity and does not by itself indicate the insider’s view of the company’s prospects.
