The shares were sold in multiple transactions at prices ranging from $45.92 to $46.52. The Reporting Person hereby undertakes to provide, upon request, to the staff of the Securities and Exchange Commission, Amkor Technology, Inc. (the "Issuer"), or any security holder of the Issuer, full information regarding the number of shares sold at each separate price within the range set forth in this footnote (1) to this Form 4. (F2) On February 21, 2025, the Reporting Person filed a Form 4 which inadvertently overreported the number of shares of common stock of the Issuer ("Shares") withheld by the Issuer in connection with the vesting of performance-vested restricted stock units to satisfy the Reporting Person's tax withholding obligations by 28 Shares. The amount of securities beneficially owned following the transaction reported in this Form 4 reflects a correction to the holdings of the Reporting Person previously reported on Form 4 since February 21, 2025, which understated holdings by 28 Shares. |
