        <footnote id="F1">As previously reported in a Form 4 filed by the Reporting Person on February 18, 2021 (the &quot;Original 2021 Form 4&quot;), on February 11, 2021 (the &quot;2021 Grant Date&quot;), 6,536 shares of Amkor Technology, Inc. (the &quot;Issuer&quot;) common stock underlying time-vested restricted stock units (the &quot;2021 RSUs&quot;) 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.</footnote>
