[144] KLA Corporation SEC Filing

Rhea-AI Filing Summary

Form 144 filing: A notice of proposed sale of 1,022 common shares through Fidelity Brokerage Services LLC on or about 08/08/2025. The securities were acquired via restricted-stock vesting on 08/07/2025 as compensation. Aggregate market value for the planned sale is listed at $933,086. Shares outstanding total 132,241,430; the planned disposition therefore represents well under 0.01 % of the issuer’s equity.

The person for whose account the shares are to be sold is identified in the past-sales table as Mary B. Wilkinson. Over the prior three months, Wilkinson completed three open-market sales totaling 4,003 shares for $3.62 million in gross proceeds (06/30/2025: 1,320 sh; 08/04/2025: 763 sh; 08/05/2025: 1,920 sh).

No other financial metrics, company outlook, or management commentary are included in this filing. The document serves solely to comply with Rule 144 disclosure requirements for the contemplated sale.

Positive

• None.

Negative

• Continued insider selling—4,003 shares sold in the past three months and an additional 1,022 planned may be viewed cautiously, though size is immaterial.

Insights

Securities Analyst

TL;DR: Routine Form 144; 1,022-share sale is de minimis vs. 132 M O/S—neutral signal.

Rule 144 filings flag insider intent to sell but do not guarantee execution. Here, the sale is minuscule (<0.01 % of shares) and follows prior small sales totaling 4,003 shares. Without price data or role of the seller, investors can view this as ordinary diversification rather than a directional statement on fundamentals. Filing contains no business updates; hence valuation or earnings outlook remain unchanged.
