As previously reported in a Form 3 filed by the Reporting Person on March 17, 2021 (the "Form 3"), on February 11, 2021 (the "2021 Grant Date"), 3,268 shares of Amkor Technology, Inc. (the "Issuer") common stock underlying time-vested restricted stock units (the "2021 RSUs") were granted to the Reporting Person. The 2021 RSUs vest in four equal annual installments beginning on the first anniversary of the 2021 Grant Date. In the Form 3 and in subsequent Forms 4 filed by the Reporting Person, the 2021 RSUs were incorrectly reported in Table I. On February 10, 2023, 817 of the 2021 RSUs vested, and such vested RSUs are properly reported in Table I of this Form 4. Table I, Column 5 and Table II, Column 9 of this Form 4 have been adjusted to include the remaining vested and unvested 2021 RSUs, respectively, and reflect the proper number of 2021 RSUs beneficially owned by the Reporting Person as of the filing of this Form 4.
As previously reported in a Form 4 filed by the Reporting Person on February 25, 2022 (the "Original Form 4"), on February 24, 2022 (the "2022 Grant Date"), 3,761 shares of the Issuer's common stock underlying time-vested restricted stock units (the "2022 RSUs") were granted to the Reporting Person. The 2022 RSUs vest in four equal annual installments beginning on the first anniversary of the 2022 Grant Date. In the Original Form 4, the 2022 RSUs were incorrectly reported in Table I. Table II, Column 9 of this Form 4 has been adjusted to include the 2022 RSUs and reflects the proper number of 2022 RSUs beneficially owned by the Reporting Person as of the filing of this Form 4.
Represents shares of the Issuer's common stock underlying time-vested restricted stock units granted on February 16, 2023 (the "2023 Grant Date") pursuant to the Issuer's 2021 Equity Incentive Plan (the "2023 RSUs"). The 2023 RSUs were awarded for no consideration other than the Reporting Person's service as an officer of the Issuer and will vest in four equal annual installments beginning on the first anniversary of the 2023 Grant Date.
