| F1 | Reflects the Reporting Person's distribution of 2,500,000 shares of Common Stock of Amkor Technology, Inc. (the "Issuer") to the 2023 Grantor Retained Annuity Trust of Susan Y. Kim dated 9/15/23 (the "SYK 2023 GRAT") on September 15, 2023. Because the Reporting Person is the annuitant and sole trustee of the SYK 2023 GRAT, such distribution was a mere change in the form of ownership from direct to indirect and hence not reportable by the Reporting Person on a Form 4. |
| F2 | 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 of the Securities Exchange Act of 1934, as amended ("Section 16"), or for any other purpose. |
| F3 | The Reporting Person is (i) a trustee of trusts for the benefit of her immediate family members (other than grantor retained annuity trusts ("GRATs")) which own 9,718,085 shares of the Issuer's Common Stock, (ii) a trustee of GRATs for the benefit of members of her immediate family which own 12,923,592 shares of the Issuer's Common Stock, (iii) a trustee of GRATs of which the Reporting Person was the settlor and is the sole annuitant which own 3,879,943 shares of the Issuer's Common Stock, (iv) a general partner of a limited partnership (Sujochil, LP) which owns 19,484,809 shares of the Issuer's Common Stock, |
| F4 | (Continued from Footnote 3) (v) a manager of limited liability companies being treated as corporations for purposes of Section 16, which own 8,200,000 shares of the Issuer's Common Stock and (vi) as referenced in Footnote 6, a member of Sujoda Management, LLC, which indirectly owns 2,478,325 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. |

Kim 2020-1 Irrevocable Trust Agreement dated 4/1/20 (the "SYK 2020-1 GRAT") to the Family Trust under the Susan Y. Kim 2020-1 Irrevocable Trust Agreement dated 4/1/20 (the "SYK 2020-1 Family Trust") on September 14, 2023. The Reporting Person and James J. Kim are co-trustees of the SYK 2020-1 GRAT and SYK 2020-1 Family Trust. Because the Reporting Person is a trustee of the SYK 2020-1 GRAT and SYK 2020-1 Family Trust, such distribution was not reportable by the Reporting Person on a Form 4. |
| F6 | The sole general partner of Sujoda Investments, LP is Sujoda Management, LLC. The Reporting Person is one of three members of Sujoda Management, LLC. Sujoda Management, LLC is being treated as a limited partnership for purposes of Section 16, and, pursuant to the Form 4 instructions, the Reporting Person has elected to treat all of the shares of the Issuer's common stock owned by Sujoda Investments, LP as beneficially owned by the Reporting Person. |
| F7 | Represents dividend equivalent units ("DEUs") accrued with respect to time-vested restricted stock units ("RSUs") of the Issuer upon the Issuer's payment of a dividend on September 25, 2023. Each DEU represents an additional RSU subject to the same provisions as the RSU with respect to which the DEU was accrued. |
(8) The Reporting Person states that the filing of this Form 4 shall not be deemed an admission that the Reporting Person is the beneficial owner of the reported securities owned by the other members of the group, for the purpose of Section 16 or for any other purpose.
