Explanation of Responses:

1. As previously reported in a Form 4 filed by the Reporting Person on February 18, 2021 (the "Original 2021 Form 4"), on February 11, 2021 (the "2021 Grant Date"), 6,536 shares of Amkor Technology, Inc. (the "Issuer") common stock underlying time-vested restricted stock units (the "2021 RSUs") were granted to the Reporting Person. The 2021 RSUs vest in four equal annual installments beginning on the first anniversary of the 2021 Grant Date. In the Original 2021 Form 4 and in subsequent Form 4s filed by the Reporting Person, the 2021 RSUs were incorrectly reported in Table I. Table II, Column 9 of this Form 4 has been adjusted to include the 2021 RSUs and reflects the proper number of 2021 RSUs beneficially owned by the Reporting Person as of the filing date of this Form 4.

2. As previously reported in a Form 4 filed by the Reporting Person on February 25, 2022 (the "Original 2022 Form 4"), on February 24, 2022 (the "2022 Grant Date") shares of the Issuer's common stock underlying time-vested restricted stock units (the "2022 RSUs") were granted to the Reporting Person. The 2022 RSUs vest in four equal annual installments beginning on the first anniversary of the 2022 Grant Date. In the Original 2022 Form 4, the 2022 RSUs were incorrectly reported in Table I. Table II, Column 9 of this Form 4 has been adjusted to include the 2022 RSUs and reflects the proper number of 2022 RSUs beneficially owned by the Reporting Person as of the filing date of this Form 4.

3. The transaction represents shares withheld by the Issuer in connection with the vesting of certain of the 2021 RSUs. 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.
