## Overview

Lam Research Corp. designs and sells wafer fabrication equipment and related services used in semiconductor manufacturing, with a focus on deposition, etch, and clean process steps. Its tools and support offerings help chipmakers build smaller, more complex devices for memory, foundry, logic, and advanced packaging applications.

## Products & services

• Wafer fabrication equipment for deposition, etch, and clean
• Customer support, spares, upgrades, and field services
• Equipment Intelligence® fleet optimization solutions
• Reliant® new and refurbished non-leading-edge products
• SABRE® electrochemical deposition systems
• ALTUS® CVD/ALD systems for advanced films

- **Systems equipment** (60%) — New wafer fabrication tools sold into deposition, etch, and clean process steps.
- **Customer support-related revenue** (30%) — Spare parts, service, upgrades, and installed-base support across the tool lifecycle.
- **Non-leading-edge products** (10%) — Reliant-branded new and refurbished tools for applications that do not need the most advanced nodes.

## Customers

Lam sells primarily to large semiconductor manufacturers that operate advanced fabs and spend heavily on process equipment. Its customer base spans memory, foundry, and logic/integrated device manufacturing, with Samsung Electronics and TSMC identified as major customers in recent filings.

- **Memory manufacturers** (primary) — Buy deposition, etch, and clean tools for DRAM and NAND process steps, plus upgrades and support to extend fab productivity.
- **Foundry customers** (primary) — Purchase advanced systems for leading-edge logic and process integration, especially where scaling and patterning complexity are rising.
- **Logic / IDM customers** (secondary) — Use Lam equipment in integrated device manufacturing flows and buy support to maintain output and process consistency.
- **Installed base / service customers** (secondary) — Buy spares, upgrades, and fleet optimization services to improve uptime, throughput, and cost per wafer.

- Large semiconductor manufacturers building memory and logic chips
- Foundry customers that need advanced process control and scaling
- IDMs using Lam tools in key wafer fabrication steps
- Installed-base customers buying spares, upgrades, and service
- Customers seeking higher throughput, yield, and defect reduction

## Geography

Lam is headquartered in Fremont, California, but operates a global network of facilities across Asia, Europe, and the United States. Revenue is heavily tied to customer fabs in Asia, especially China, Taiwan, Korea, Japan, and Southeast Asia, which makes the company sensitive to export controls, trade restrictions, and regional capex cycles.

- **China** (39%) — Q3 FY2026 six-month revenue mix disclosed in MD&A
- **Taiwan** (20%) — Q3 FY2026 six-month revenue mix disclosed in MD&A
- **Korea** (17%) — Q3 FY2026 six-month revenue mix disclosed in MD&A
- **Japan** (10%) — Q3 FY2026 six-month revenue mix disclosed in MD&A
- **Southeast Asia** (7%) — Q3 FY2026 six-month revenue mix disclosed in MD&A
- **United States** (5%) — Q3 FY2026 six-month revenue mix disclosed in MD&A
- **Europe** (2%) — Q3 FY2026 six-month revenue mix disclosed in MD&A

- Headquartered in Fremont, California, with global operations
- Revenue is attributed to customer fab location, not billing entity
- Asia is the main demand center for semiconductor equipment
- China, Taiwan, and Korea are the largest disclosed revenue regions
- International sales expose Lam to export controls and FX risk

## Strategy

Lam is focused on sustaining R&D investment in leading-edge deposition, etch, and clean technologies while protecting its installed base through service and upgrade offerings. Management also emphasizes liquidity, cost discipline, and capital returns as it navigates cyclical semiconductor spending, trade restrictions, and customer concentration.

- **Advance process technology in deposition, etch, and clean** (medium-term) — Differentiated tools are needed to win share as chipmakers adopt more complex device architectures.
- **Monetize the installed base** (short-term) — Service, spares, and upgrades provide recurring revenue and deepen customer relationships.
- **Preserve financial flexibility** (short-term) — Cyclical demand and trade-related volatility require liquidity to sustain R&D and operations.

- Invest in leading-edge deposition, etch, and clean R&D
- Expand served market through 3D scaling and advanced packaging
- Grow customer support revenue from the installed base
- Maintain liquidity to fund R&D, capex, and downturn resilience
- Return capital through repurchases and dividends

## Risks

Lam’s business is exposed to semiconductor capex cycles, customer concentration, and rapid technology shifts that can reduce demand for its limited product set. It also faces material geopolitical and operational risks from export restrictions, supply chain disruptions, cybersecurity threats, and the fact that a large share of revenue is generated outside the United States.

- **Customer concentration** [high] — A small number of large semiconductor manufacturers account for a significant share of shipments and revenue.
- **Semiconductor industry cyclicality** [high] — Customer investment in wafer fabrication equipment rises and falls quickly with memory and foundry spending.
- **Trade restrictions and export controls** [high] — A large portion of sales and operations occur outside the U.S., especially in Asia.
- **Technology concentration** [medium] — The company relies on a relatively narrow set of process steps and product lines.
- **Cybersecurity and IP protection** [high] — Loss of sensitive data or disruption of systems could affect operations, customer trust, and R&D value.

- Customer concentration can swing revenue and margins if one buyer slows spending
- Semiconductor capex cycles drive sharp changes in equipment demand
- Export controls and tariffs can limit sales in key Asian markets
- Limited product lines increase exposure to technology substitution
- Supply chain and cybersecurity incidents can disrupt manufacturing and service

## Accounting

Lam’s reported results are sensitive to revenue recognition judgments, inventory valuation, and tax estimates, all of which can move gross margin and earnings. The company also has meaningful quarter-to-quarter mix effects between systems and customer support revenue, and it evaluates uncertain tax positions and deferred tax assets regularly because a large share of pre-tax income is earned outside the United States.

- **Revenue recognition** — Can shift quarterly revenue and margin
- **Inventory valuation** — Directly affects gross margin
- **Income taxes and uncertain tax positions** — Can change effective tax rate and net income
- **Customer support revenue mix** — Affects quarterly comparability and profitability

- Revenue recognition affects timing of systems and service sales
- Inventory valuation can materially affect gross margin
- Customer support mix changes can alter quarterly comparability
- Deferred tax assets and uncertain tax positions require judgment
- International earnings create tax-rate sensitivity
