LRCX earnings analysis
What we found in LRCX's 10-K: the parts that mattered, the offsets in the same document, and what the company said about what comes next.
Our reading of the filing · Free to read, no account needed
Lam delivered a strong FY2026, with revenue up 26.0% to $23.233 billion, diluted EPS up 38.8% to $5.76, gross margin expanding 180 basis points to 50.5%, and foundry, Taiwan, systems, and support revenue driving growth. Its strategy is aligned with AI-driven semiconductor investment and increasing process complexity, supported by deposition, etch, clean expertise, a broad installed base, and sustained R&D spending of $2.376 billion. The outlook remains structurally positive, but China export controls, customer concentration, tariffs, supply-chain disruption, and the volatility of AI-related capital spending create meaningful downside risks.
The parts that mattered.
Pulled out of the filing itself, with the figures the company reported.
- Strong three-year earnings acceleration
- FY2026 revenue increased 26.0% to $23.233 billion from $18.436 billion in FY2025 and $14.905 billion in FY2024. Net income rose 35.6% to $7.265 billion, while diluted EPS increased to $5.76 from $4.15 in FY2025 and $2.90 in FY2024.
- Margin expansion despite tariffs
- Gross margin expanded to 50.5% in FY2026 from 48.7% in FY2025 and 47.3% in FY2024; operating income reached $8.200 billion, implying a 35.3% operating margin versus 32.0% in FY2025 and 28.6% in FY2024. Management attributed the gross-margin improvement largely to favorable customer mix despite aluminum and steel tariff costs.
- Positioned for AI-era process inflections
- Lam identifies deposition, etch, and clean leadership, a broad installed base, customer collaboration, and multi-product solutions as sources of differentiation. AI, 3D device scaling, multiple patterning, process-flow changes, and advanced packaging are described as longer-term drivers of the served market.
- Foundry and systems led growth
- Foundry was the principal market growth driver, increasing to 54% of equipment and upgrade revenue from 45% in FY2025, while memory declined to 39% from 42% and logic/integrated device manufacturing declined to 7% from 13%. Systems revenue grew 29.5% to $14.885 billion, and customer support revenue increased 20.2% to $8.347 billion.
- Taiwan and Asia drove geographic growth
- Growth was broad across key regions: Taiwan revenue rose to $5.223 billion from $3.445 billion, Southeast Asia to $1.246 billion from $837 million, and Korea to $4.505 billion from $4.128 billion. China remained the largest region at $7.860 billion, or 34% of revenue.
- Substantial cash returns and investment
- Free cash flow, calculated as operating cash flow less capital expenditures, was approximately $4.891 billion in FY2026 ($5.858 billion less $966.4 million), versus approximately $5.414 billion in FY2025 and $4.256 billion in FY2024. The company returned $5.12 billion through $3.85 billion of share repurchases and $1.27 billion of dividends, while also repaying $755.4 million of debt and investing $966.4 million in capital expenditures.
And the other side of it.
The offsets in the same document — the things a summary that only listed the good news would have left out.
- New Middle East supply-chain shock
- The filing identifies a new February 2026 conflict involving the United States, Israel, Persian Gulf states, and Iran, which disrupted the Strait of Hormuz and Red Sea and adversely affected the supply and prices of oil, LNG, aluminum, helium, bromine, and sulfur. The company states that continuation or escalation could materially and adversely affect operations, margins, and cash flows.
- AI demand and execution uncertainty
- AI is both a growth driver and a newly emphasized execution risk: Lam says AI-related spending is driving semiconductor equipment demand, but slower AI adoption, improved compute efficiency, oversupply, architecture changes, or regulation could rapidly reduce customer capital spending. The company also warns that failure to scale manufacturing and hiring in response to AI-driven demand could cause lost market share, while AI-enabled attacks and data leakage create additional cybersecurity exposure.
- Greater customer concentration
- Customer and credit concentration increased materially: in FY2026, four customers represented approximately 16%, 15%, 12%, and 12% of total revenue, and five customers represented approximately 20%, 16%, 15%, 11%, and 10% of accounts receivable. The filing warns that a single customer’s investment decisions, pricing demands, shipment delays, or inability to pay could materially affect revenue, margins, cash flow, and liquidity.
- China controls and rare-earth exposure
- China remains a significant regulatory exposure at 34% of FY2026 revenue, or $7.860 billion, although down from 42% in FY2024. The filing says expanded U.S. export-license requirements and possible future controls could limit sales, weaken Lam’s competitive position, and materially adversely affect revenue and profits; China is also the primary source of certain rare-earth elements critical to manufacturing.
- Debt service constrains flexibility
- The company had $3.75 billion of senior notes outstanding at June 28, 2026, with contractual interest payments of $2.042 billion over the disclosed payment periods. Although Lam repaid the $750.0 million 2026 Notes at maturity and had no commercial-paper or revolver borrowings, debt service competes with capital expenditures, dividends, repurchases, and acquisitions.
- Input-cost and PFAS regulation risk
- Tariffs on steel and aluminum increased FY2026 manufacturing costs and adversely affected margins, while proposed PFAS restrictions could reduce the availability of parts and materials incorporated into Lam products. The company states that suitable replacements may not be available at similar costs or at all.

What they said about what is next.
The 10-K provides no annual numeric revenue or EPS guidance. It states that current cash flows and liquidity are expected to support operations, investments, debt service, capital expenditures, capital returns, and dividends for at least the next twelve months; quarterly outlook was provided separately in the Q4 earnings release.
