A stock is a share of ownership in a company. Owning one means you own a small piece of that business.

In the company's own words, from Item 1 (Business) of its latest annual report (Form 10-K) filed with the SEC on 2025-08-08.

Our suite of advanced products, coupled with our unique process control software and services, allow us to deliver the solutions our customers need to achieve their technology advancement and high-volume production goals by significantly improving yields, while simultaneously reducing waste, risks and costs.

KLA was formed as KLA-Tencor Corporation in April 1997 through the merger of KLA Instruments Corporation and Tencor Instruments, two long-time leaders in the semiconductor capital equipment industry that began operations in 1975 and 1976, respectively. We are organized into three reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection.
