On August 1, 2024, KLA's Board of Directors and Compensation and Talent Committee determined that the performance conditions applicable to the first tranche of these PRSUs were satisfied at 131% of target shares. The first tranche of these PRSUs (8,241.210) vested on June 30, 2025, and were subject to the continued service of the reporting person. |
| F5 | Pursuant to the terms of the grant, shares of KLA common stock were automatically withheld to cover required tax withholding on the 8.241.210 shares of KLA common stock that vested. The fair market value of KLA common stock used for purposes of calculating the number of shares to be withheld was the closing price of KLA common stock as reported on June 30, 2025. |
