Lam Research Corporation (LRCX) | The Buildout — AI Infrastructure

The Verdict

Lam Research supplies wafer fabrication equipment and services to the semiconductor industry — the tools that deposit, etch and clean films on silicon wafers. It sits upstream of the chipmakers: foundries, memory makers and logic manufacturers buy its capital equipment, then buy spares, services and upgrades for as long as the tools run. AI accelerators, HBM stacks and high-capacity storage all depend on process inflections that raise deposition and etch intensity, and Lam sells into those inflections. Management now frames AI as the organizing driver of the wafer-fab-equipment cycle.

Earnings Beat

Revenue was a record $6.72B, up 15% sequentially and 30% year over year. Company-reported gross margin was 52%, the highest in 20 years, and operating margin was 38.4%. The standout was NAND: systems revenue from non-volatile memory more than doubled sequentially, taking NAND to 23% of systems revenue from 12%. The customer support business set a third consecutive record at about $2.5B.

Management tone: Management's language hardened versus prior-period references without becoming promotional. The prepared remarks opened on AI as the organizing frame and closed on relative outperformance. Management was direct on items that cut against the story — the tax rate stepping to the mid-teens, September gross margin guided flat at 52%, and lead times described as challenging — and declined repeated requests to put a number on 2027.

Management Guidance

For the September 2026 quarter, non-GAAP guidance is revenue of $8.1B ±$400M, gross margin of 52% ±1 percentage point, operating margin of 39.5% ±1 percentage point and EPS of $2.15 ±$0.15, on a share count of approximately 1.255 billion. The non-GAAP tax rate steps from 11% to the mid-teens, due to more revenue in higher-tax jurisdictions, primarily the United States, and a higher U.S. GILTI rate; management expects that to continue 'for the remainder of 2026 and likely beyond.' Capex remains framed at 4% to 5% of revenue.

Trajectory

Revenue has set four consecutive records, reaching $6.72B in the June 2026 quarter, with sequential growth stepping up from 0.4% in December 2025 to 15.1% in June and September guided above 20%. The mix rotated toward memory: Memory rose to 46% of systems revenue from 39%, with NAND dollars more than doubling sequentially, while Foundry fell to 44% from 54%. Company-reported gross margin rose to 52% and operating margin to 38.4%. CSBG compounded off installed-base upgrades and spares.

The Model

The model projects FY+1 revenue of $34,800M and EBITDA of $14,616M, a 42.0% margin, and FY+2 revenue of $40,500M and EBITDA of $17,820M, a 44.0% margin. The near term is anchored by the September quarter's guided $8.1B and by management's calendar-2026 WFE outlook in the low $150B range. FY+2 depends on the 2027 setup management calls extraordinary — DRAM-led WFE growth, then leading-edge foundry/logic, then NAND — plus the installed-base conversions and advanced packaging that carry the systems and CSBG lines. The five runs behind the median carry a 20% revenue spread in FY+1 and 27% in FY+2.

Projections are the median of 5 independent model runs. The model’s revenue sits 11.2% above analyst consensus.

For the September 2026 quarter, non-GAAP guidance is revenue of $8.1B ±$400M, gross margin of 52% ±1 percentage point, operating margin of 39.5% ±1 percentage point and EPS of $2.15 ±$0.15, on a share count of approximately 1.255 billion. The non-GAAP tax rate steps from 11% to the mid-teens, due to more revenue in higher-tax jurisdictions, primarily the United States, and a higher U.S. GILTI rate; management expects that to continue 'for the remainder of 2026 and likely beyond.'

What Could Go Right — and Wrong

Looking Ahead

Over the next 12 months the test is conversion rather than demand. Lam has guided the September 2026 quarter and said the second half of 2026 offers little room for unexpected upside because lead times are challenging. Management pointed to 8-10 new customer fabs coming online between now and the end of 2027, a first 310×310mm panel tool shipping this year, and additional Dextro and Equipment Intelligence service revenue in the second half. The company also committed more than $3B over five years to expand its global R&D lab network, with the Oregon lab groundbreaking on 2026-08-26. The unresolved item is 2027, which management calls an extraordinary setup but has declined to quantify.

The Company

Lam Research supplies wafer fabrication equipment and services to the semiconductor industry. Its tools deposit, etch and clean films on silicon wafers — the steps that determine how small and how well performing a chip can be. The 10-K describes core competencies in nanoscale manufacturing enablement, chemistry, plasma and fluidics, and advanced systems engineering. Product families include SABRE electroplating, ALTUS and VECTOR deposition, Kiyo and Flex etch, Coronus bevel clean, and the Reliant line of new and refurbished non-leading-edge tools.

Lam runs two businesses in effect. Systems is new wafer fab equipment. CSBG, the Customer Support Business Group, covers upgrades, spares, services, Reliant, and increasingly Equipment Intelligence and Dextro collaborative maintenance robots; it is discussed as a distinct revenue stream but is not a reported segment. The company reports one segment overall. Manufacturing runs across Oregon, California, Ohio, Malaysia, Taiwan, Korea and Austria, and management describes those sites as deliberately not all interrelated, so they are not all driven by the same demand.

Business Segments

Competitive Landscape

Lam competes across deposition, etch and clean. The 10-K names Applied Materials as its primary competitor in dielectric and metals deposition, and Applied Materials, Hitachi and Tokyo Electron as its primary etch competitors. It also competes against ASM International and Wonik IPS in ALD and PECVD, and against Screen Holding, Semes and Tokyo Electron in wet clean. Management describes strong positions in conductor etch and in TSV etch and electroplating for advanced packaging.

Supply Chain

Lam buys gas and chemical delivery subsystems, RF power, and specialty materials from a set of suppliers, then sells finished wafer-fab equipment to foundries and memory makers. No neighbor transcript named Lam; verified relationships come from filings and counterparty calls.
