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.
