Maker of equipment that etches, deposits and cleans layers on chip wafers. Lam sells semiconductor processing systems (deposition, etch and clean tools) to chipmakers producing logic and memory devices.
How Lam Research makes money
Lam sells semiconductor processing systems (deposition, etch and clean tools) to chipmakers producing logic and memory devices. It also earns recurring revenue from customer service, spare parts, upgrades and refurbished equipment for its installed base.
What Lam Research does
Lam Research, founded in 1980 and headquartered in Fremont, California, designs, manufactures and services the equipment used to fabricate integrated circuits. Its lineup covers three core steps of chipmaking: deposition (ALTUS for tungsten/molybdenum metallization, SABRE copper electrochemical deposition, Striker atomic layer deposition, VECTOR plasma-enhanced CVD), etch (Kiyo and Akara conductor etch, Flex and Vantex dielectric etch, Syndion deep silicon etch, Versys metal etch, and the Argos, Prevos and Selis selective etch systems), and cleaning (Coronus bevel clean, Da Vinci, DV-Prime, EOS and SP series). The company serves chipmakers producing advanced logic and memory devices in the United States, China, Korea, Taiwan, Japan, Southeast Asia and Europe. Beyond new systems, it sells refurbished tools under the Reliant brand, offers the Sense.i platform, and provides service, spare parts and upgrades for equipment already installed in customer fabs.

What is Lam Research worth?
On an owner-earnings DCF, Lam Research's most-likely value is about $99 versus a recent price near $319 (69% above fair value). But TacticScale only calls a stock undervalued when the price sits below its conservative no-growth floor (~$36) 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 →
