| F1 | On August 4, 2022, in addition to the RSUs granted that were subject to only service-based vesting conditions, the Reporting Person was also granted RSUs with both performance-based and service-based vesting conditions ("PRSUs") for a target number of shares equal to 894.000 shares of KLA common stock. The maximum number of shares issuable under these PRSUs is 150% of the target shares if KLA's free cash flow relative to its peers was at the 75th percentile or greater for the three years in the period ended June 30, 2025. On August 7, 2025, KLA's Board of Directors and Compensation and Talent Committee determined that the performance conditions applicable to these PRSUs were satisfied at the maximum level. Fifty percent (50%) of the PRSUs will vest today, August 7, 2025, and the remaining fifty percent (50%) of the PRSUs will vest on August 4, 2026, subject to continued service of the Reporting Person. |
| F2 | The number of shares of KLA common stock includes 2,205.000 shares issuable upon vesting of restricted stock units ("RSUs"). |
| F3 | On August 7, 2025, fifty percent (50%) of the performance-based restricted stock units granted on August 4, 2022 vested. Pursuant to the terms of the grant, shares of KLA common stock were automatically withheld at vesting to cover required tax withholding. 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 August 6, 2025. |
