, we also reimburse directors for travel and other reasonable out-of-pocketexpenses incurred by them in attending Board and committee meetings. Directors who are also employees or officers of Amkor, including Mr. Rutten, our President and Chief Executive Officer, do not receive annual retainers for their service on our Board of Directors. Equity Compensation Upon election to the Board of Directors at the 2024 Annual Meeting, each non-employeedirector was granted an equity award of time-vested restricted stock units (“RSUs”) with a fair market value on the grant date of $195,000, rounded down such that only whole shares are issued, pursuant to the Director Compensation Policy and the terms of the Amkor Technology, Inc. 2021 Equity Incentive Plan (as amended, the “2021 Equity Plan”). Subject to the terms and conditions of the RSU award agreement for non-employeedirectors: (i) the RSUs will vest in full on the earlier of the first anniversary of the grant date or the date of the Company’s first annual meeting of the stockholders immediately following the grant date; and (ii) upon the Company’s payment of a cash dividend, dividend equivalent units (“DEUs”) accrue with respect to the underlying RSUs, with DEUs representing additional RSUs subject to the same vesting provisions as the underlying RSUs. Under our stock ownership guidelines, each non-employeedirector is expected to directly or indirectly own shares of our common stock equal in value to five times the annual cash retainer for non-employeedirectors. 19

Each non-employeedirector is expected to achieve the ownership guideline within five years after the date on which such director became subject to the ownership guideline and to retain 50% of the after-taxshares of common stock acquired or retained upon the exercise of a stock option or vesting of a restricted stock unit until such director satisfies the stock ownership guidelines. As of December 31, 2024, all of our non-employeedirectors either owned more than the minimum level of our common stock or were otherwise in compliance with the stock ownership guidelines.
