        <footnote id="F1">As previously reported in a Form 4 filed by the Reporting Person on May 19, 2022 (the &quot;Original Form 4&quot;), 8,706 shares of Amkor Technology, Inc. (the &quot;Issuer&quot;) common stock underlying time-vested restricted stock units (the &quot;RSUs&quot;) were granted to the Reporting Person on May 17, 2022. Pursuant to the award agreement for the RSUs, dividend equivalent units (&quot;DEUs&quot;) accrue with respect to the RSUs when and as dividends are paid on the Issuer's common stock. In the Original Form 4 and the Form 4 filed by the Reporting Person on March 1, 2023, the RSUs were incorrectly reported in Table I. Table I, Column 5 has been adjusted to include the proper number of non-derivative securities beneficially owned by the Reporting Person, and 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, in each case as of the filing date of this Form 4.</footnote>
        <footnote id="F2">Represents DEUs accrued with respect to the RSUs upon the Issuer's payment of a dividend on March 20, 2023. Each DEU represents an additional RSU subject to the same provisions as the RSU with respect to which the DEU was accrued.</footnote>
