Insights

Financial Analyst

TL;DR: Routine, pre-planned insider sale and a small gift; holdings remain substantial and include vested RSUs.

The filing documents a Rule 10b5-1 plan-driven sale of 10,801 shares at $913.68 and a gift of 804 shares, both on 08/12/2025. Use of an established 10b5-1 plan reduces the likelihood these transactions were timed based on nonpublic information. The reporting person still beneficially owns over 92,000 shares, of which 57,511.168 are RSU-related, indicating continued equity exposure to KLAC.

Corporate Governance Expert

TL;DR: Insider complied with 10b5-1 procedures; disclosure is timely and standard for an officer.

The Form 4 discloses compliance with a 10b5-1 trading plan adopted on November 1, 2024, and the transactions are signed by an attorney-in-fact. Reporting shows both a sale and a gift rather than any unusual acceleration or amendment. The disclosure of RSU inclusion in beneficial ownership is appropriate and provides clarity on long-term incentive overlap.
