Explanation of Responses:

1. As previously reported in a Form 4 filed by the Reporting Person on February 25, 2022 (the "Original Form 4"), shares of Amkor Technology, Inc. (the "Issuer") common stock underlying time-vested restricted stock units (the "2022 RSUs") were granted to the Reporting Person on February 24, 2022. In the Original 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.

2. As previously reported in a Form 3 filed by the Reporting Person on October 12, 2021 (the "Form 3"), shares of the Issuer's common stock underlying time-vested restricted stock units (the "2021 RSUs") were granted to the Reporting Person on February 11, 2021. In the Form 3 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.

3. The sale reported in this Form 4 was effected pursuant to a Rule 10b5-1 trading plan adopted by the Reporting Person on September 1, 2022.

4. This stock option ("the Option") to acquire 100,000 shares of the Issuers common stock (the "Option Shares") was granted on February 15, 2019 (the "Grant Date") and vests over four years as follows: (i) with respect to 25% of the Option Shares, on the first anniversary of the Grant Date; and (ii) with respect to the remainder of the Option Shares, in equal quarterly installments thereafter, such that 100% of the Option will vest on the fourth anniversary of the Grant Date.
