On August 4, 2022, the Reporting Person was granted restricted stock units ("RSUs") of shares of KLA common stock. On August 4, 2026, twenty-five percent (25%) of the RSUs 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 3, 2026.

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. The remaining fifty percent (50%) of the PRSUs vested on August 4, 2026. 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 3, 2026.
