KLA Corporation
KLA Corporation, together with its subsidiaries, provides process control and process-enabling solutions for manufacturing wafers, reticles/masks, chemicals/materials, integrated circuits (ICs), packaged ICs, and printed circuit boards. It operates through three segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection. The company offers inspection and review tools to identify, locate, characterize, review, and analyze defects on various surfaces of patterned and unpatterned wafers; chemical process control equipment; wired and wireless sensor wafers and reticles; wafer defect inspection, review, and metrology systems; reticle inspection and metrology systems; wafer inspection and metrology systems; semiconductor software solutions; KLA Pro systems; and specialty semiconductor manufacturing, benchtop metrology, surface characterization, material strength characterization, and electrical property measurement products. It also provides etch, plasma dicing, deposition and other wafer processing technologies and solutions; direct imaging, inspection, optical shaping, inkjet, and additive printing, as well as computer-aided manufacturing and engineering solutions; and components. In addition, the company offers service programs. It serves semiconductor, and semiconductor-related and electronic device manufacturers. The company operates in China, Taiwan, Korea, North America, Japan, Europe, Israel, and rest of Asia. The company was formerly known as KLA-Tencor Corporation and changed its name to KLA Corporation in July 2019. KLA Corporation was incorporated in 1975 and is headquartered in Milpitas, California.
What does it do?
KLA makes inspection tools that chip manufacturers use to catch defects before they become expensive problems. Think of it like a quality control camera that looks at silicon wafers during production and spots microscopic flaws invisible to the human eye. The company also inspects the masks (blueprints) used to print circuits, and checks circuit boards before they ship. Without KLA's tools, chip makers would waste billions producing defective products.
KLA is a gatekeeper in chip manufacturing—every advanced semiconductor made today depends on their inspection equipment. As the world scrambles to build more chips for AI, data centers, and consumer electronics, demand for KLA's tools has exploded. The company essentially profits from the entire semiconductor boom without bearing the capital risk of actually building fabs (factories).
How does it make money?
KLA generates revenue almost entirely from selling and servicing inspection equipment to semiconductor manufacturers. They earn money upfront when a chip maker buys a tool (which can cost millions), then recurring revenue from maintenance, software updates, and spare parts. Last year they pulled in $13.6 billion in revenue, up 11% from $12.2 billion the prior year, with a net profit of $4.8 billion, meaning roughly 35% of revenue drops to the bottom line as earnings.
Why do investors care?
Investors are betting that chip manufacturing capex (capital spending) will stay elevated for years as companies build new fabs to meet AI demand and reduce reliance on Taiwan. KLA's customers—Intel, Samsung, TSMC, and others—are spending record amounts on equipment, and KLA captures a slice of every expansion. The company also has pricing power because their tools are essential and hard to replace, which means margins could expand if they can grow revenue faster than costs.
