Lam Research Corporation

What they do

Lam Research designs and manufactures semiconductor processing equipment used in the fabrication of integrated circuits, offering systems and services for deposition, etch, and clean processes. The company also provides advanced packaging solutions for back-end wafer-level packaging, including fan-out panel-level packaging. Its services business, the Customer Support Business Group, maximizes installed equipment performance, predictability, and operational efficiency.

Revenue drivers

• Systems revenue — Sales of new leading-edge equipment in deposition, etch, and clean; $4.25 billion in Q4 FY2026, 63% of total revenue.
• Customer support-related revenue and other — Services, spare parts, and upgrades for installed base; $2.47 billion in Q4 FY2026, 37% of total revenue.
• Geographic segments — Revenue concentrated in Asia: Taiwan 27%, China 26%, Korea 20% of Q4 FY2026 revenue; Japan, US, Southeast Asia, and Europe each under 10%.

Recent performance

For the quarter ended June 28, 2026, Lam reported record revenue of $6.72 billion, up 15.1% sequentially from $5.84 billion in March 2026. GAAP gross margin was 51.7%, operating margin 37.4%, and diluted EPS $1.81, compared to 49.8%, 35.0%, and $1.45 in the prior quarter. Non-GAAP diluted EPS was $1.82, up from $1.47. For fiscal year 2026, revenue was $23.23 billion, up 26% from $18.44 billion in fiscal 2025.

Strategy

Lam is investing in R&D to support technology inflections such as 3D device scaling, multiple patterning, and advanced packaging. It focuses on multi-product solutions and collaboration with ecosystem partners to enhance customer value. Management cites leadership in deposition, etch, and clean markets and a strong installed base as keys to differentiation. The company also aims to leverage AI-driven demand to achieve a third consecutive year of outperformance in 2026.

Risks

• Trade restrictions and tariffs — The company notes that volatility from trade restrictions, tariffs, and related uncertainties could negatively impact revenue and operating margin.
• Customer concentration — A significant portion of revenue comes from a limited number of large semiconductor manufacturers; order timing and cancellations can cause quarterly volatility.
• Supply chain disruptions — The company's operations depend on suppliers; constraints or material cost increases could affect production and profitability.
• AI demand cyclicality — While AI drives current growth, a slowdown in semiconductor spending or shifts in technology can reduce demand for its equipment.

Outlook

Management sees strong wafer fabrication equipment investments in 2025 and 2026, driven by AI market demand across memory and non-memory segments. In the short term, trade restrictions and tariffs pose risks, but over the longer term, secular semiconductor demand and technology inflections are expected to expand the served available market. The company anticipates continued growth, having reported record revenue and operating margin in the June quarter.
