The company’s September guidance signals more than 20% sequential top-line growth, fueled by AI-driven demand and technology transitions across NAND, DRAM, and advanced packaging. With its expanding served available market and operational scale, LAM is positioned to outpace wafer fab equipment growth into 2027.
Summary
- NAND Acceleration: Storage system demand for AI doubled NAND revenue, reshaping LAM’s growth profile.
- Service Expansion: Upgrades and automated fab solutions drove a third straight quarter of record support revenue.
- AI-Driven Opportunity: Technology inflections in memory and packaging signal multi-year outperformance potential.
Business Overview
LAM Research designs and manufactures semiconductor wafer fabrication equipment, specializing in etch and deposition tools used to build advanced memory and logic chips. The company’s revenue streams include systems sales (new tools for chipmakers), and its Customer Support Business Group (CSBG), which provides upgrades, spares, and services for installed equipment. Major segments are memory (NAND and DRAM), foundry/logic, and services, with a global customer base spanning leading semiconductor manufacturers.
Performance Analysis
Record revenue, margin, and EPS marked LAM’s June quarter, with top-line growth led by a surge in NAND demand and robust service activity. Systems revenue mix shifted sharply toward memory, as NAND accounted for 23% of systems sales, up from 12% last quarter. DRAM remained strong and stable, while foundry/logic demand concentrated in advanced nodes and packaging.
The Customer Support Business Group delivered its third consecutive record, with revenue up 17% sequentially and 43% year-over-year, driven by upgrades and increased fab utilization. Gross margin reached a 20-year high, reflecting favorable product mix, pricing actions, and operational scale. Inventory levels rose to support demand, but inventory turns improved to a five-year peak, underscoring supply chain discipline.
- Memory Mix Shift: Memory represented 46% of systems revenue, with NAND more than doubling sequentially, highlighting the impact of AI storage needs.
- Regional Dynamics: Taiwan set a new revenue record, while China’s share declined as domestic demand softened but multinational activity remained resilient.
- Margin Expansion: Gross margin hit 52%, driven by pricing, scale, and product mix, supporting record operating profit and EPS.
Capital returns remained disciplined, with 45% of free cash flow returned via buybacks and dividends. Headcount growth focused on manufacturing and R&D to support the ongoing ramp and new product initiatives.
Executive Commentary
"Sequential top line growth was led by a doubling of NAND revenue from the prior quarter, underscoring the growing importance of storage to AI system performance. Our customer support business group also posted strong revenue growth driven by robust demand for upgrades, reliant, and equipment intelligence enabled services."
Tim Archer, President and Chief Executive Officer
"We were pleased with our continued strong execution in the June quarter, resulting in our fourth consecutive quarter of record revenue, our highest quarterly gross margin in 20 years, record operating margin, and record earnings per share."
Doug Bettinger, Executive Vice President and Chief Financial Officer
Strategic Positioning
1. Memory Technology Inflections
AI-driven demand is accelerating NAND and DRAM technology transitions, with customers converting installed base to 200+ layer NAND and advancing DRAM nodes. LAM’s opportunity per wafer is set to double as layer counts and complexity rise, expanding its served available market (SAM) and deepening its competitive moat in etch and deposition.
2. Advanced Packaging Leadership
Advanced packaging revenue is on track for over 70% growth this year, as industry shifts toward panel-level and high-bandwidth memory (HBM) solutions for AI applications. LAM’s early investments and technical leadership in panel tools and electroplating position it as a key enabler of next-generation chip architectures.
3. Service and Automation Upside
The CSBG segment is outpacing installed base growth, driven by upgrades, spares, and the adoption of dextro cobots, collaborative maintenance robots, and equipment intelligence. These automation solutions boost fab output and tool availability, creating recurring revenue opportunities as they expand from NAND into DRAM customers.
4. Operational Velocity and Global Manufacturing
LAM’s diversified global manufacturing footprint (with sites in the US, Asia, and Europe) enables rapid response to customer demand spikes and reduces supply chain risk. Scale efficiencies and close-to-customer strategies are contributing to structural margin gains and support the company’s ability to capture upside in tight supply environments.
5. Product Innovation and Market Share Expansion
New platforms such as ACARA (direct drive plasma etch) and Argos (selective edge treatment) are driving share gains in leading-edge foundry/logic and DRAM. LAM’s co-optimized solutions deliver both performance improvements and customer cost savings, reinforcing its position at the forefront of critical process technologies.
Key Considerations
Strategic context for the quarter centers on AI-driven demand, memory technology inflections, and LAM’s expanding role in advanced packaging and automation. Operational execution and product innovation continue to underpin outperformance versus wafer fab equipment (WFE) market growth.
Key Considerations:
- NAND and DRAM Layer Scaling: Rising layer counts and device complexity are expanding LAM’s SAM, with each new node driving higher tool intensity and process times.
- Service Revenue Leverage: Upgrades, spares, and automation services are generating high-margin recurring revenue, with adoption broadening across memory types.
- Regional Shifts: Taiwan’s foundry/logic investments set new records, while China’s mix is shifting toward multinationals as domestic demand softens.
- Margin Trajectory: Gross margin expansion is being driven by pricing, product mix, and operational scale, with a multi-year path toward mid-50% targets.
- Capacity and Inventory Management: LAM is balancing inventory build with improved turns to support growth while maintaining cash discipline.
Risks
Potential oversupply in NAND, as flagged by third-party forecasts, could pressure memory fundamentals if consumer demand weakens. China’s domestic customer slowdown introduces regional volatility, while lead time constraints and cleanroom availability may limit upside in the near term. Gross margin expansion depends on sustaining pricing and operational gains amid competitive and macro uncertainties.
Forward Outlook
For the September quarter, LAM guided to:
- Revenue of $8.1 billion, plus or minus $400 million
- Gross margin of 52%, plus or minus one percentage point
- Operating margin of 39.5%, plus or minus one percentage point
- EPS of $2.15, plus or minus $0.15
For full-year 2026, management expects:
- WFE spending of $150 billion
- Continued outperformance versus WFE growth, with DRAM as the fastest grower next year, followed by foundry/logic and NAND
Management highlighted:
- Continued momentum in memory and advanced packaging segments
- Service revenue and automation as recurring growth drivers
Takeaways
LAM’s Q4 2026 results underscore its leverage to AI-driven semiconductor demand, with NAND and service segments fueling record performance and a robust outlook. Margin expansion and operational scale are supporting multi-year outperformance against WFE benchmarks.
- AI and Memory Transitions: The accelerating shift to higher-layer NAND and advanced DRAM nodes is structurally expanding LAM’s market share and revenue per wafer.
- Services and Automation: The installed base and automation solutions are creating durable, high-margin growth engines beyond core systems sales.
- Watch for: Sustained service momentum, DRAM’s outperformance, and the pace of advanced packaging adoption as key drivers into 2027.
Conclusion
LAM Research enters the second half of 2026 with accelerating revenue, margin expansion, and a path to multi-year growth driven by AI, memory scaling, and advanced packaging. The company’s operational execution and product innovation position it to capture outsized share as semiconductor complexity and demand rise.
