Explanation of responses 8 footnotes
Footnote F1
Restricted Stock Awards vest in three equal annual installments beginning on the first anniversary of the grant date.
Footnote F2
Withholding of common stock shares to satisfy tax withholding obligations in connection with the vesting of previously granted awards.
Footnote F3
The Compensation Committee certified achievement of pre-established performance goals related to High Growth Segments and HBM3E+, each at 266% of target under the performance-based restricted stock units ("PRSUs") with a three-year performance period granted on October 13, 2023. The payout for the PRSUs (if earned) varies (starting at 0%) based on actual achievement of the goals, subject to a 200% aggregate limit on the total target shares that may be received under the PRSUs awarded on October 13, 2023. The reported shares represent shares earned upon certification of performance at the conclusion of the three-year performance period, including shares earned based on second-year performance that remained subject to vesting and shares earned based on third-year performance. All such shares vested upon certification of performance at the end of the three-year performance period.
Footnote F4
The Compensation Committee certified achievement of pre-established performance goals related to total shareholder return at 150% of target under the PRSUs with a three-year performance period previously awarded on October 13, 2023. The payout for the PRSUs (if earned) varies (starting at 0%) based on actual achievement of the goals, subject to a 200% aggregate limit on the total target shares that may be received under the PRSUs awarded on October 13, 2023. As a result of this limitation, the final payout for these PRSUs was reduced to 126% of target after application of the aggregate payout provisions. The reported shares represent shares earned upon certification of performance at the conclusion of the three-year performance period, including shares earned based on second-year performance that remained subject to vesting and shares earned based on third-year performance. All such shares vested upon certification of performance at the end of the three-year performance period.
