Lam Research builds etch and deposition equipment. Etch is the step that sculpts the wafer. The more layers a stacked memory has, the more times it has to be etched. That is why memory pulls Lam in a way it does not pull a company that only sells lithography.
The customer is again the short list: memory fabs and logic fabs. Service on tools already installed is the part that does not switch off when a new order slips. Lam does not replace Applied or ASML. It sits at another step on the same line.
The memory cycle is sharper than logic. A year of depressed DRAM prices can cut capex even though etch is still needed over the long run. Export controls do the same job as in the rest of the equipment industry: they take customers out of the addressable market.
Sustainable Competitive Advantage
"The moat is etch chemistry already qualified in the fab and the base of tools that must be maintained. Replacing it in the middle of a stacked-memory process means rewriting the recipe. It is not a monopoly on every tool on the wafer. Applied and Tokyo Electron occupy neighbouring steps. The moat narrows if memory stops stacking layers, or if a fab qualifies someone else on the same etch."

Health is that of an equipment maker, not of a designer with no plants. Quality looks at the etch margin and the service margin. Growth is cyclical with memory and with logic capex, and it can go backwards for a full year. Valuation looks expensive at the order peak and cheap at the trough, which is the usual equipment trap. Shareholder return waits until the cycle's cash allows it.
Do not use the P/E of a memory peak as if it were normal earnings. Through-cycle EV/EBITDA, and cash flow after the working capital of the tools, are the multiples that hold. Compare Lam with Applied on margin and on the weight of service, not on a one-point P/E gap. A dash means LRCX is missing from the cache.

Questions from this report
What moat does Lam Research have?
The moat is etch chemistry already qualified in the fab and the base of tools that must be maintained. Replacing it in the middle of a stacked-memory process means rewriting the recipe. It is not a monopoly on every tool on the wafer. Applied and Tokyo Electron occupy neighbouring steps. The moat narrows if memory stops stacking layers, or if a fab qualifies someone else on the same etch.
