Amkor (AMKR) Director Robert R. Morse Receives Dividend-Equivalent RSUs

What Happened
Robert Randolph Morse, a director of Amkor Technology, received two grants of dividend-equivalent units (DEUs) that converted into additional restricted stock units (RSUs). On March 31, 2026 he was credited with 15.725 DEUs and 18.156 DEUs (total 33.881 units). Each unit was recorded at $0.00 (no cash paid); DEUs simply represent additional RSUs tied to existing awards.

Key Details

  • Transaction date: March 31, 2026. Report filed April 2, 2026 (timely filing).
  • Grants: 15.725 DEUs (F1) and 18.156 DEUs (F2); price per unit $0.00; total acquired = 33.881 RSU equivalents.
  • Footnotes: F1 = DEUs from dividend on RSUs granted May 16, 2023; F2 = DEUs from dividend on RSUs granted May 15, 2025. Each DEU is an additional RSU subject to the same vesting/terms as the underlying RSU.
  • Shares owned after the transaction: not disclosed in the provided filing excerpt.
  • Transaction code: "A" = award/grant (derivative conversion), not a market purchase or sale.

Context
DEUs are a routine mechanism that accrues additional RSUs when the company pays cash dividends on outstanding RSUs. This is not a cash purchase or sale and does not by itself indicate a change in insider sentiment. The additional units remain subject to the same vesting and restrictions as the original RSU grants.
