Explanation of Responses:
1. This Form 4 reports the vesting on February 20, 2024 of 21,377 shares of common stock of Amkor Technology, Inc. (the "Issuer") underlying performance-vested restricted stock units ("PSUs") granted to the Reporting Person on February 24, 2022 pursuant to the Issuer's Equity Incentive Plan, as amended, and the related award agreement. The PSUs vested based on the attainment of a basic cumulative earnings per share performance goal over a two-year performance period beginning January 1, 2022 and ending on December 31, 2023.
2. The transaction represents shares of the Issuer's common stock withheld by the Issuer in connection with the vesting of PSUs to satisfy the Reporting Person's tax withholding obligations. The Issuer will pay these taxes on behalf of the Reporting Person.
3. Represents shares of the Issuer's common stock underlying time-vested restricted stock units granted on February 20, 2024 (the "Grant Date") pursuant to the Issuer's Equity Incentive Plan (the "RSUs"). The RSUs were awarded for no consideration other than the Reporting Person's service as an officer of the Issuer and will vest in three equal annual installments beginning on the first anniversary of the Grant Date and annually thereafter, such that 100% will be vested on the third anniversary of the Grant Date.
