The Reporting Person hereby undertakes to provide, upon request, to the staff of the Securities and Exchange Commission, Amkor Technology, Inc.

As previously reported in a Form 4 filed by the Reporting Person on February 24, 2023 (the "Original Form 4"), 6,250 shares (the "Option Shares") of the Issuer's common stock underlying an option to acquire 100,000 shares of the Issuer's common stock were exercised and sold on February 23, 2023. Pursuant to the award agreement for the Option Shares, the expiration date for the Option Shares is February 15, 2029. In the Original Form 4, the expiration date for the Option Shares was incorrectly reported. Table II, Column 6 has been adjusted to include the proper expiration date for the Option Shares.
