        <footnote id="F1">On August 4, 2022, the Reporting Person received a grant of restricted stock units (&quot;RSUs&quot;). The RSUs vest 25% annually from the date of grant.</footnote>
        <footnote id="F2">The number of shares of KLA common stock includes 48,958 shares issuable upon vesting of RSUs.</footnote>
        <footnote id="F3">On August 1, 2019, in addition to the RSUs granted on that date that were subject only to service-vesting requirements (which RSUs were previously reported on a Form 4), the Reporting Person was also granted RSUs covering up to a maximum of 19,294 shares (based on 150% of the target shares of 12,863) of KLA common stock, subject to both performance-vesting and service-vesting requirements. On August 4, 2022, the Compensation and Talent Committee of KLA's Board of Directors determined the level at which the corporate performance goals were attained and, based on the assessment, determined that the number of shares subject to the RSUs is 19,294.</footnote>
        <footnote id="F4">The number of shares of KLA common stock includes 58,604 shares issuable upon vesting of RSUs.</footnote>
        <footnote id="F5">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 4, 2022.</footnote>
