| F1 | On January 27, 2022, the Reporting Person filed a Form 4 (the "Original Form 4") which inadvertently omitted a transaction which resulted in an increase in the indirect holdings of the Reported Person as the trustee of a trust for the benefit of members of the Reporting Person's immediate family. On December 27, 2021, a transfer of 164,678 shares of the Common Stock of Amkor Technology, Inc. (the "Issuer") was made to a limited liability company being treated as a corporation for purposes of Section 16 of the Securities Exchange Act of 1934, as amended ("Section 16"). The Reporting Person is a trustee of a trust which is a member of such limited liability company. The beneficiaries of the trust are members of the Reporting Person's immediate family. The trust is being treated as the "controlling shareholder" of the limited liability company for purposes of Section 16. |
| F2 | (Continued from Footnote 1) Although the above described transfer of shares of the Issuer's Common Stock was not reported on the Original Form 4, such shares were correctly included in the indirect holdings of the Reporting Person on the Original Form 4 |
| F3 | The Reporting Person is a trustee of trusts for the benefit of his immediate family members (excluding his own grantor retained annuity trusts and the Qualified Annuity Trust Under the Susan Y. Kim 2018-1 Irrevocable Trust Agreement dtd 8/29/18) which own 12,678,815 shares of the Issuer's Common Stock. Pursuant to the Form 4 instructions, the Reporting Person is being treated as having a pecuniary interest in all of such shares. The Reporting Person disclaims beneficial ownership of these securities, except to the extent of the Reporting Person's pecuniary interest therein, and this report shall not be deemed an admission that the Reporting Person is the beneficial owner of such securities, except to the extent of the Reporting Person's pecuniary interest therein, for purposes of Section 16, or for any other purpose. |
