Amkor (AMKR) CEO Kevin K. Engel Receives RSUs; Shares Withheld

What Happened

  • Kevin K. Engel, President, CEO and Director of Amkor Technology, received awards totaling 82,252 shares (various restricted stock units) on February 18, 2026. These awards include vested performance-vested RSUs (PSUs) and newly granted time-vested RSUs.
  • On the same date, 3,212 shares were surrendered/withheld to satisfy tax withholding obligations (dispositions reported at $46.74 per share), generating proceeds/value of approximately $150,129 (814 shares ≈ $38,046; 2,398 shares ≈ $112,083).
  • This is primarily an award/vesting event (A = award/grant); the F-coded transactions reflect shares withheld to cover taxes (not an open-market sale).

Key Details

  • Transaction date: February 18, 2026; Form 4 filed February 20, 2026 (appears timely).
  • Prices reported: awards at $0.00 (granted for service or vested); withheld/disposed shares reported at $46.74 each.
  • Share counts: 1,777 PSUs vested (from 2024 grant); 5,594 PSUs vested (from 2025 grant); 53,487 and 21,394 time-vested RSUs granted on Feb 18, 2026 (total awards = 82,252). Withholding/dispositions: 814 and 2,398 shares (total 3,212).
  • Shares owned after transaction: not specified in the provided filing excerpt.
  • Notable footnotes:
    • PSUs vested based on attainment of basic EPS goals for the 2025 performance period (footnotes F1 and F3).
    • Withheld shares were used to satisfy tax withholding; the issuer will pay these taxes on the reporting person’s behalf (F2).
    • Newly granted RSUs vest over multi-year schedules (three-year and two-year schedules described in F4 and F5).
  • Transaction codes: A = Award/Grant, F = Tax withholding/disposition.

Context

  • These transactions are mainly awards and vesting events rather than open-market purchases or sales; the withheld shares represent tax-withholding actions, not discretionary market sales.
  • Performance-vested RSUs (PSUs) indicate shares earned based on company performance metrics; time-vested RSUs will vest over future dates per the award terms.
  • For retail investors, awards and tax-withholding are routine corporate compensation mechanics and do not by themselves indicate a buy/sell signal.
