Explanation of Responses:

( 1 )Each restricted stock unit ("RSU") represents a contingent right to receive one share of KLA common stock. ( 2 )On March 20, 2019, the reporting person was granted performance-based RSUs that would be eligible to vest, subject to continued service on each vesting date, in three equal installments as early as the third, fourth and fifth anniversaries of the grant date provided that the trailing 20-day average of the closing price of KLA common stock plus cash dividends distributed per share since the grant date exceeded $174.5865, $203.6843 and $232.782, respectively. On November 20, 2019, it was determined that the 20-day trailing average plus cash dividends distributed per share since the grant date exceeded the first threshold of $174.5865. As a result, 13,813 shares became eligible to vest on March 20, 2022, subject to continued service on that date. ( 3 )Does not include performance-based RSUs, if any, held by the Reporting Person for which an assessment has not yet been made regarding the achievement of the applicable performance goals. Any such holdings will be reported on a Form 4 within two business days of the date such assessment is made.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
