LAM Research (LRCX) Q1 2026: China Revenue Set to Drop Below 30% as AI-Driven Demand Lifts Global Mix

October 22, 2025 | By EarningsIQ Research

LAM Research enters 2026 with record profitability and a global revenue mix shift, as China exposure drops and AI-driven investments in memory and logic drive new growth levers. Strategic product wins and a resilient services business offset regulatory headwinds, positioning LAM for continued outperformance as the industry’s technology roadmap accelerates.

Summary

• Global Mix Shift: China’s revenue share will fall below 30% in 2026, as multinationals drive spending.
• AI Infrastructure Tailwind: Surging AI data center demand expands LAM’s served market and product attach rates.
• Profitability at Scale: Record margins and operating leverage reflect execution and advanced services growth.

Performance Analysis

LAM Research delivered record quarterly revenue and margins, closing out the September quarter above $5.3 billion in revenue, with gross margin at 50.6% and operating margin reaching 35%. The company’s Customer Support Business Group (CSBG), services and spares unit, generated $1.8 billion, growing sequentially and year-over-year, and remains a solid pillar of margin accretion. Foundry represented 60% of systems revenue, up from 52% last quarter, while memory’s share declined to 34% as investment timing shifted among customers.

China accounted for 43% of total revenue, up from 35% in the prior quarter, but this was driven by domestic Chinese customers rather than multinationals. LAM expects a sharp reversal in 2026, with China’s share dropping below 30% due to new U.S. export restrictions and robust global demand. Operating expenses rose modestly, largely from R&D and field support headcount to sustain product innovation and customer installations. Capital deployment remained aggressive, with nearly $1 billion in buybacks and a dividend increase, underscoring confidence in long-term cash generation.

• Foundry Strength: Leading-edge and mature node investments, especially outside China, drove record Foundry revenue mix.
• CSBG Resilience: Recurring services, spares, and upgrades outpaced installed base growth, supporting margin durability.
• China Volatility: Near-term revenue was elevated, but regulatory headwinds set up a material mix shift in 2026.

Profitability remains anchored by product differentiation in etch and deposition, as well as operational discipline. Tariff and mix headwinds are expected to pressure margins in coming quarters, but scale and services should buffer downside.

Executive Commentary

Strategic Positioning

1. AI-Driven Market Expansion

AI data center investment is reshaping demand for advanced semiconductor manufacturing equipment. LAM estimates every $100 billion in AI data center capex translates to $8 billion in wafer fab equipment (WFE) spend, with LAM’s core etch and deposition products capturing a rising share. The company’s attach rate is projected to climb from the low 30% range to the high 30s as leading-edge nodes proliferate.

2. NAND Upgrade Cycle and Installed Base Leverage

The multi-year NAND upgrade wave remains a core growth engine. LAM expects over $40 billion in upgrade spending as the industry transitions to 200+ layer devices. The company’s large installed base and proprietary technologies, such as Cryo 3.0 and Halo ALD, position it to capture a disproportionate share of this investment. Upgrades are the fastest and lowest-cost path for customers to boost performance, extending LAM’s relevance even as new capacity additions lag due to cleanroom constraints.

3. Advanced Packaging and Product Innovation

Advanced packaging is emerging as a new vector for growth, with LAM’s Sabre 3D, Cindi, and Edge systems leading the market. The company is investing in panel-level packaging, collaborating with ecosystem partners to standardize and scale next-generation integration. Early customer adoption and a growing installed base support long-term share gains as packaging complexity rises.

4. Resilient Services Model

CSBG’s recurring revenue from spares, services, and upgrades continues to grow faster than the installed base, providing margin stability and a buffer against cyclical swings in systems revenue. Margin accretion from CSBG supports overall profitability, even as mix and tariff headwinds emerge.

5. Geographic Revenue Rebalancing

Regulatory restrictions are forcing a sharp reduction in China exposure, with LAM guiding to less than 30% of revenue from China in 2026. This mix shift will be offset by accelerating investments from global multinationals in the U.S., Taiwan, and Korea, supporting both growth and strategic de-risking.

Key Considerations

This quarter marks a pivotal transition for LAM, as AI infrastructure demand, regulatory impacts, and customer investment cycles reshape the company’s opportunity set and risk profile. The company’s ability to convert technology leadership into recurring revenue and margin expansion will be tested as the market’s center of gravity shifts globally.

Key Considerations:

• AI Data Center Demand: LAM’s technology portfolio is tightly aligned with the most demanding AI workloads, supporting sustained growth in etch and deposition intensity.
• NAND Upgrade Acceleration: Higher-than-expected bit demand is pulling forward upgrade cycles, but cleanroom constraints may cap the pace of capacity additions.
• Services Margin Resilience: CSBG’s recurring revenue and margin accretion are offsetting cyclicality in systems sales, reinforcing LAM’s business model durability.
• China Revenue Headwind: U.S. export controls will reduce China revenue by an estimated $600 million in 2026, but global demand is expected to more than offset this headwind.
• Tariff and Mix Pressure: Customer mix normalization and rising tariffs will weigh on gross margin, requiring continued operational discipline.

Risks

Regulatory pressure remains the most material risk, with new U.S. rules restricting shipments to Chinese customers set to reduce revenue and drive mix volatility. Tariff escalation and customer mix normalization will challenge gross margin. Physical infrastructure constraints, such as cleanroom availability, could limit the pace of NAND and advanced packaging growth. Cyclical swings in memory and foundry investment plans remain a persistent risk to near-term visibility.

Forward Outlook

For the December quarter, LAM guided to:

• Revenue of $5.2 billion, plus or minus $300 million
• Gross margin of 48.5%, plus or minus one percentage point
• Operating margin of 33%, plus or minus one percentage point
• EPS of $1.15, plus or minus $0.10

For full-year 2026, management did not provide explicit revenue guidance but stated:

• WFE growth will be “second half weighted,” with China headwinds offset by global strength
• China revenue will fall below 30% of total, with global multinationals driving the offset

Management highlighted that tariff and mix headwinds will pressure gross margin, and the effective tax rate will rise slightly as global minimum tax regimes phase in. Investors should expect more detailed 2026 sub-segment guidance on the next call.

Takeaways

Investors should recognize LAM’s strategic pivot from China-centric growth to a more balanced, AI-driven global opportunity set. The company’s leadership in etch, deposition, and advanced packaging, combined with a resilient services model, underpins margin strength even as regulatory and mix headwinds emerge.

• Global Demand Diversification: Robust foundry, DRAM, and NAND investment from multinationals is offsetting China revenue risk, supporting growth into 2026.
• Product and Services Leverage: Proprietary technology and a growing installed base are driving both new system sales and recurring services margin.
• Regulatory and Margin Watchpoints: Ongoing U.S.-China tensions and tariff escalation require vigilance, as does the impact of customer mix on profitability. Investors should monitor the pace of AI-driven WFE spending and the evolution of LAM’s geographic revenue mix in 2026.

Conclusion

LAM Research exits Q1 2026 with record profitability and a clear pivot toward global, AI-driven growth, as China’s revenue share recedes and product innovation sustains operating leverage. The company is well-positioned to capitalize on the next wave of semiconductor complexity, but investors should track regulatory, margin, and infrastructure risks as the cycle matures.
