[Form 4] KLA Corporation Insider Trading Activity

Rhea-AI Filing Summary

Form 4 shows KLA Corp. (KLAC) EVP & CFO Bren D. Higgins settling tax withholdings triggered by scheduled RSU vesting, not an open-market trade. Two Code “F” transactions were reported:

• 08/03/25: 722.381 shares withheld at $886.64 after 25 % of a 5,828-unit 2023 RSU grant vested.
• 08/04/25: 738.743 shares withheld at the same price following 25 % vesting of a 5,961-unit 2022 RSU grant.

Post-withholding, Higgins directly owns 23,182.006 KLAC shares, including 13,213.912 unvested RSUs. Because Code “F” indicates share retention for taxes, the filing is routine and signals no directional change in insider sentiment or corporate outlook.

Insights

Securities Analyst

TL;DR: Routine tax-withholding; no bullish or bearish signal.

These Code “F” dispositions reflect automatic share surrender to cover taxes on vested RSUs. Higgins retains a sizable holding (≈ 23 k shares), so equity exposure remains intact. No open-market selling or buying occurred, limiting market relevance. Neutral for valuation or sentiment models.

Corporate Governance Expert

TL;DR: Standard Section 16 compliance; administrative.

The filing complies with Section 16(a) and Rule 10b5-1(c) disclosure standards. Transactions are plan-based, avoiding potential optics of opportunistic trading. No governance red flags emerge.
