Explanation of Responses:

Id Content
F1 On February 22, 2024, the Reporting Person filed a Form 4 (the "Previous Form 4") which inadvertently underreported by 28 shares the number of shares of Amkor Technology, Inc. (the "Issuer") common stock ("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. As a result, the Previous Form 4 inadvertently reported that the Reporting Person beneficially owned 4,411 Shares as of February 20, 2024, instead of 4,383. As of February 23, 2024, the Reporting Person beneficially owned 4,921 Shares.
F2 The transaction represents shares withheld by the Issuer in connection with the vesting of certain restricted stock units ("RSUs") granted to the Reporting Person on February 24, 2022 (the "Grant Date") pursuant to the Issuer's 2021 Equity Incentive Plan, as amended, and the related award agreement. These shares were withheld to satisfy the Reporting Person's tax withholding obligations. The Issuer will pay these taxes on behalf of the Reporting Person.
F3 On the Grant Date, the Reporting Person was granted 3,761 RSUs which vest in four equal annual installments beginning on the first anniversary of the Grant Date.
