How KLA makes money
KLA earns most of its money selling costly process control, inspection and metrology systems to semiconductor and electronics manufacturers. It also earns recurring revenue from service programs, software and components for its large installed base of tools.
What KLA does
KLA Corporation, known as KLA-Tencor until 2019, supplies process control and process-enabling solutions to the semiconductor and electronics industries. Its core business is Semiconductor Process Control: inspection, review and metrology systems for patterned and unpatterned wafers and reticles, plus sensor wafers, chemical process control equipment and analytics software. These tools help chipmakers find defects and control yield across many manufacturing steps. Its other two segments are Specialty Semiconductor Process, which includes etch, plasma dicing and deposition technologies, and PCB and Component Inspection, which includes direct imaging, inspection, inkjet and additive printing, and CAM/CAE software. KLA also runs service programs for its installed tools. It sells to customers in China, Taiwan, Korea, North America, Japan, Europe and Israel. The company was founded in 1975 and is headquartered in Milpitas, California.

What is KLA worth?
On an owner-earnings DCF, KLA's most-likely value is about $80 versus a recent price near $196 (59% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$29) with a margin of safety — so the honest verdict here is “Fairly priced — no edge.” Fair value earns its keep only at the extremes, not in the wide middle.
Price sits in the normal range — fair value isn't actionable here; it earns its keep only when price drops below the no-growth floor, or runs to roughly double the optimistic case.
Analysis, not advice. Fair value is a margin-of-safety estimate from a deterministic owner-earnings DCF, not a price target or recommendation. See the full breakdown →
