Lam Research

Business description

Lam Research is a global leader in wafer fabrication equipment (WFE) and services for the semiconductor industry. The company specializes in etch and deposition processes, which are critical for the manufacturing of advanced logic and memory chips.

Key financials

• CY2026 WFE Outlook: USD 140 billion (industry-wide).
• Revenue Growth: Projected to remain consistently strong at 20%+.
• **H-Score:**75 (Strong Momentum and Multi-factor score).

Competitive moat

Lam Research holds a dominant position in the plasma etch and deposition market. Its installed base—the industry's largest for 3D NAND equipment—creates a significant recurring revenue stream through the Customer Support Business Group (CSBG). It is a critical partner for leading chipmakers as they transition to advanced nodes like Gate-All-Around (GAA) and High-Bandwidth Memory (HBM).

Recent developments

• 2026-05-03: Analyst rating lifted to Buy (from Hold). Management is navigating supply chain and cleanroom constraints while producing above-consensus results.
• NAND Recovery: Pulling forward its ~ NAND upgrade/new equipment forecast to the end of 2027 due to strengthening bit demand.
• Molybdenum Transition: Beneficiary of the industry-wide shift from tungsten to molybdenum for >300 layer NAND devices, which may also extend to DRAM and logic.
• Strategic Concentration: Lam remains the primary customer for key subsystem suppliers like [[Comet Holding AG]] (78% of PCT revenue) and [[VAT Group AG]].

Investment risks / red flags

• China Exposure: China business remains elevated (34% of Q3 sales). Risks from MATCH Act and local competitors gaining capabilities via government funding ( incentive package).
• Customer Concentration: Sensitive to the capital spending cycles of major foundries and memory manufacturers (TSMC, Samsung, Intel).

H-Score signals

• TBI multi factor score: 75
