Applied Materials
Thesis
- The business: one of the WFE five-firm oligopoly (AMAT, LRCX, KLAC, ASML, TEL).
- Moat:
- Subscription-based service with growing installed base
- Breath enabled co-optimization at inflections. AMAT has the broadest materials engineering portfolio (everything except lithography).
- More process steps per wafer as devices go 3D.
- 3.6 billion R&D and industry positioning.
- Earnings drivers: Leading edge logic and DRAM CapEx. Content increase at inflections (gate-all-around, backside power, HBM, packaging). Pricing to value.
- Competition: etch (Lam), process control (KLA), China (NAURA, AMEC, Piotech).
- Risks:
- Export compliance enforcement.
- China substitution.
- Spend shifting to steps applied does not serve (lithography, NAND).
- Customer concentration.
- Capacity commitments at the peak.
- What to watch: TSMC and memory capex, DRAM prices, China share and export rules, NAURA/AMEC growth.
Lam versus Applied Materials
- Applied's moat is breadth plus co-development; Lam's is depth in the steps that are multiplying.
- The tension: Applied has the stronger overall power position but the weaker growth cells. Lam is growing fastest precisely where its customers are most concentrated, so its growth depends on a few buyers it cannot control.
- Breadth protects Applied's share, not its price. Lam's cost edge is real but cyclical.
- Lam leads in margin conversion due to structural (counts per wafer rises as chips go vertical) and operating leverage. Installed base services is larger and growing faster. Faster growing served market and rising market share. Faster asset turnover. No China footprint.
- Applied is more resilient. Lam has higher customer concentration, higher memory exposure, and more cyclical margin.
- Risk for Lam: Customer concentration. NAND conversion due to end in 2027.
- Risk for Applied: China mature node demand. Fixed capex cost.
