 noted otherwise in the table, the material assumptions that we used in creating the table are as follows:

| • |     | Price per Share of Common Stock. Calculations requiring a per share stock price are made using the closing price of our common stock on December 31, 2024, which was $25.69. Any actual amounts paid under these scenarios, should they occur in the future, may be different. |

| • |     | Generally Available Compensation and Benefits. For purposes of this section, we have excluded amounts that would become payable under programs that are generally available to Amkor’s salaried employees (e.g., the 401(k) Plan and Company-provided life insurance) and other post-termination compensation generally available to Amkor’s salaried employees (e.g., earned but unpaid salary and accrued but unused vacation time). |

| • |     | Assumption of Equity Awards Following a Change in Control. Except as otherwise set forth in the table below, the values shown for a Change in Control assume that a Qualifying CIC Termination has occurred for purposes of the Executive Severance Agreements. |

| • |     | Performance Goal Attainment. The values included in the table below and attributable to the settlement of PSUs and payments made under the Executive Bonus Plan assume an actual attainment of |

43

| 100% for the applicable performance period. The actual attainment levels under these scenarios, should they occur in the future, may be different. |

| • |     | Restrictive Covenants. To the extent that that we have any post-termination compensation arrangement that requires any of our NEOs to execute a general release of claims in favor of Amkor or to comply with the terms of any non-competition, non-solicitation, confidentiality, or similar restrictive covenant as a condition to receiving post-termination compensation payments pursuant to such arrangement, we have assumed that the NEO has complied with all such requirements. |

| • |     | Executive Bonus Plan. We describe the Executive Bonus Plan in the CD&A under “Elements of Our Compensation Program — Annual Incentive Opportunities.” Amounts earned by and paid to the NEOs during 2024 under the Executive Bonus Plan are disclosed in the Summary Compensation Table. |
