Explanation of Responses:

1. As previously reported in a Form 4 filed by the Reporting Person on May 19, 2022 (the "Original Form 4"), 8,706 shares of Amkor Technology, Inc. (the "Issuer") common stock underlying time-vested restricted stock units (the "RSUs") was granted to the Reporting Person on May 17, 2022. In the Original Form 4, the RSUs were incorrectly reported in Table I. Table II, Column 9 of this Form 4 has been adjusted to include the RSUs and reflects the proper number of RSUs beneficially owned by the Reporting Person as of the filing date of this Form 4.

2. This stock option (the "Option") to acquire 20,000 shares of the Issuer's common stock (the "Option Shares") was granted on February 6, 2013 (the "Option Grant Date") and vested as follows: (i) with respect to 1/3 of the Option Shares, on the first anniversary of the Option Grant Date; (ii) with respect to 1/3 of the Option Shares, on the second anniversary of the Option Grant Date; and (iii) with respect to the remainder of the Option Shares, on March 5, 2015.
