    Executive summary

    Lam Research Q4 FY25 — Record Gross Margin and Strong Foundry/NAND Performance

    Lam Research delivered a strong Q4 FY25, achieving record gross margins and EPS, driven by robust foundry and NAND upgrades. The company is executing on its served available market expansion strategy, with new products gaining traction in advanced packaging and gate-all-around architectures. While WFE spending is now expected to be flat half-on-half for CY25, Lam remains confident in its outperformance due to technology inflections and product leadership.

    Highlights

    5
    • Achieved record gross margin of 50.3% in the post-Novellus period.

    • Record revenue of $18.4 billion and free cash flow of $5.4 billion (29% of revenue) for FY25.

    • Record foundry revenues, driven by gate-all-around and mature nodes, and upgrades business grew mid-teens percent QoQ.

    • Secured key win for ALD Moly at another leading foundry customer for next-generation application, with Lam being the only company with ALD Moly in production.

    • Expanded Dextro cobot capabilities to 3 additional tool types, accelerating roadmap for autonomous fab vision.

    Concerns

    4
    • Gross margin expected to decline to ~48% in December quarter due to mix, tariffs, and slightly softer revenue.

    • Operating expenses increased to $822 million from $763 million QoQ, primarily due to increased incentive compensation.

    • DRAM revenue declined to 14% of systems revenue from 23% QoQ due to timing of certain customer projects.

    • China revenue in December quarter expected to lighten up after a strong September, contributing to gross margin headwinds.

    Increased tariff headwindsDecember quarter

    incrementally higher in December quarter

    Mitigation: Included in gross margin guidance.

    Less favorable customer and product mixDecember quarter

    Mitigation: Included in gross margin guidance.

    Softer overall revenueDecember quarter

    December quarter revenue expected to be down

    Mitigation: Included in gross margin guidance.

    Timing of certain customer projects in DRAMQ4 FY25

    DRAM revenue declined to 14% of systems revenue from 23% QoQ

    Mitigation: Not explicitly stated, but FY25 DRAM revenue was a record, suggesting project timing rather than fundamental weakness.

    Current50.3%
    Target~48%

    Why it matters

    Gross margin is a key profitability metric, and management guided a notable decline due to mix and tariffs. Verifying this trend is crucial for profitability outlook.

    You should be kind of thinking about where consensus is today, which is about 48%. I think that's what you're going to see in December.

    Q&A highlights

    6

    What are the key factors contributing to Lam's expected growth significantly above the overall WFE market?

    Tim Archer cited gate-all-around, advanced packaging, HBM, NAND layer scaling, moly, selective etch, ALD, backside power, and dry resist as key technology drivers. He emphasized that etch and deposition intensity continues to rise faster than WFE, and Lam's strong product portfolio positions it for SAM expansion and share gains.

    It's all the things that we've talked about in the past. I mean, clearly, if we look at foundry/logic, I mentioned extensively the discussion of moly today, but we're also looking at other tools around the gate-all-around structure. It's things like selective etch, ALD. We still have backside power to come.

    Detailed Narrative

    01

    Record Profitability and Operational Execution

    Lam Research achieved a record gross margin of 50.3% in Q4 FY25, the highest since the Lam-Novellus merger, and record EPS. For FY25, the company reported record revenue of $18.4 billion and free cash flow of $5.4 billion (29% of revenue). This performance is attributed to a growing top line, favorable mix, and strong operational efficiencies from its close-to-customer manufacturing strategy.

    02

    Market Outperformance and SAM Expansion

    The company expects to outperform WFE growth in CY25 and CY26, driven by its strong position in gate-all-around, advanced packaging, HBM, and NAND layer conversions. Lam's served available market (SAM) is projected to expand to mid-30s percent of WFE in CY25 and is on track to reach high 30% range longer term, with an expectation to win over 50% share of the incremental SAM.

    03

    Advanced Technology Inflections (Moly)

    Lam is leading the industry transition to ALD Moly, with its Halo ALD Moly tool ramping at multiple NAND customers and already in production in foundry/logic. This technology addresses RC challenges below 2nm gate-all-around structures, driving a roughly 3x increase in Lam's metal deposition SAM per wafer for advanced nodes. The company secured a key win at a leading foundry customer for next-gen applications.

    04

    Advanced Packaging Leadership

    Advanced packaging is a critical growth driver, with Lam's SAM expanding due to increased adoption in DRAM, CPUs, GPUs, and ASICs for data centers. The company's SABRE 3D system, leveraging 20 years of copper plating experience and over 6,000 installed plating cells, is gaining market share, expected to grow nearly 5 points year-on-year in CY25.

    05

    Etch Technology Wins

    Lam solidified its leadership in high aspect ratio dielectric etch for NAND with its Vantex system winning a multigeneration etch decision at a major NAND customer. The new Akara conductor etch tool, launched earlier this year, secured multiple new application wins at a top DRAM maker, demonstrating industry-leading depth uniformity and profile control vital for DRAM scaling.

    06

    Customer Support Business Group (CSBG) Momentum

    CSBG revenue was approximately $1.7 billion, consistent with the prior quarter. The upgrades business achieved its third consecutive record quarter, driven by NAND technology conversions. The company also highlighted momentum with its Equipment Intelligence enabled Dextro cobots, expanding capabilities to 3 additional tool types, enhancing tool-to-tool matching, machine availability, and operational costs.
