KLA Corporation supplies advanced process control, metrology, software and services to semiconductor, packaging and PCB manufacturers. Its services business represented approximately 22% of revenue in fiscal 2025, and international sales accounted for about 89% of total revenues in fiscal 2025 and 2024. Backlog declined from $9.83 billion at June 30, 2024 to $7.86 billion at June 30, 2025, and the company expects to recognize roughly 71%–76% of the backlog as revenue in the next 12 months and another 20%–25% in the following 12 months.

The filing highlights material concentrations and risks: revenue from customers in China was 33% of revenue in 2025 (43% in 2024), and two customers (including Taiwan Semiconductor Manufacturing Company and Samsung) each accounted for more than 10% of revenues in recent years. KLA reports over 8,500 active patents, ~15,000 full-time employees, ~131.96 million shares outstanding as of July 21, 2025 and an aggregate market value of approximately $83.7 billion as of December 31, 2024. The company discloses significant regulatory and trade risks—notably evolving U.S. export controls, China-related restrictions and recent tariffs—that it says could materially affect shipments, backlog and future revenue recognition.

Mary Beth Wilkinson, EVP, CLO and Secretary of KLA Corporation, reported multiple restricted stock unit (RSU) events on Form 4 dated 08/07/2025. A performance-based RSU grant from 08/04/2022 with a target of 2,385 shares achieved its performance goal at the maximum (150%) and 50% vested on 08/07/2025, with the remaining 50% scheduled to vest on 08/04/2026 subject to continued service. A second performance tranche (target 1,677 shares) was determined at 147% of target and will vest on 06/30/2026 if service conditions are met. The filing notes that shares were automatically withheld to cover tax withholding using the closing price on 08/06/2025, and that Wilkinson received a new RSU grant on 08/07/2025 that vests 25% annually. The form also lists several counts of shares issuable upon vesting (for example 5,974.194, 4,184.694, 6,649.884, 7,794.972), which the filing states are included in the reported amounts.

Insider vesting and grant activity at KLA (KLAC) is reported for Richard P. Wallace. Performance-based restricted stock units (PRSUs) granted in 2022 reached their performance targets: one PRSU tranche had a target of 24,146 shares and was certified at a maximum payout of 150%, with 50% of those PRSUs vesting immediately and the remaining 50% scheduled to vest one year later, subject to continued service. A second PRSU tranche with a target of 6,291 shares was certified at 147% of target and will vest on the scheduled future vesting date, subject to continued service. Fifty percent of vested PRSU shares were withheld to satisfy tax withholding using a closing price of $888.28 per share. The reporting person also received a new RSU grant that vests 25% annually. These actions convert performance awards into common stock and adjust the reporting person's beneficial ownership as shown on the form.
