Key Factors to Watch This Quarter
1. NAND Momentum and Upgrade Cycle
- Management expects most of the $40B NAND upgrade cycle to be completed by end of 2027, with greenfield capacity additions to follow.
- Q4 FY2026 saw NAND revenue more than double sequentially, driven by conversions to 256-layer and above devices.
- Watch for commentary on the pace of upgrades vs. greenfield, and any update to the size/timing of the next upgrade cycle (300+ layers).
2. DRAM/HBM and Advanced Packaging Growth
- DRAM remains a key growth driver, especially with HBM and advanced nodes (1c, 1-gamma).
- Advanced packaging revenue is now expected to grow >70% YoY in 2026, up from >50% earlier in the year.
- Monitor for continued share gains in DRAM, HBM, and advanced packaging, as well as adoption of panel-level packaging.
3. Gross Margin Expansion and Sustainability
- Gross margin reached 52.0% in Q4 FY2026 (highest in 20 years); guidance is for 52.0% again in Q1 FY2027.
- Management targets mid-50% gross margin over the next several years, driven by scale, product mix, pricing, and operational efficiency.
- Investors will look for evidence that these margins are sustainable as volumes ramp and customer mix evolves.
4. CSBG (Customer Support Business Group) Performance
- CSBG posted a third consecutive record quarter at nearly $2.5B revenue (+43% YoY).
- Growth is driven by upgrades, spares, service, and advanced services (cobots, Equipment Intelligence).
- High utilization rates across the industry are supporting strong spares/service demand.
- Watch for continued outperformance and commentary on incremental growth drivers.
5. China Exposure and Regional Mix
- China revenue declined to 26% in Q4 FY2026 (from 34% in Q3), with global multinationals in China growing while domestic customers declined.
- Management expects China WFE to be flat to slightly up YoY, but as a percent of total, China will decline as other regions grow faster.
- Monitor for any regulatory or competitive developments impacting China business.
6. Supply Chain, Inventory, and Capacity
- Inventory turns improved to 3x in Q4 FY2026 (highest in almost 5 years), with inventory up $300M QoQ to support growth.
- Second Malaysia facility coming online in H2 2026 to support increased demand.
- Lead times are stretched but Lam is focused on not being the bottleneck for customers.
7. Pricing Power and Product Mix
- Management cited pricing actions, operational efficiencies, and favorable product mix as drivers of recent gross margin outperformance.
- New products (Akara, Vantex, Halo, advanced packaging tools) are contributing to higher value capture.
- Investors will look for continued evidence of pricing discipline and mix improvement.
8. Visibility and Demand Outlook for 2027
- Management and customers are signaling robust demand visibility into 2027, with 8–10 new Tier 1 fabs coming online.
- Cleanroom constraints are easing but still present; 2027 is expected to be another strong growth year.
- Watch for updates on customer order patterns, long-term agreements, and Lam’s ability to scale.

Management Commentary — Recent Tone and Focus
- On Demand and Visibility:
"AI is driving unprecedented demand, greater technical requirements and accelerated architectural scaling at both the device and packaging level... We see 2026 shaping up to be our third consecutive year of relative outperformance to WFE. Looking into 2027, we see an extraordinary setup for WFE growth." - On Margins:
"Gross margin was stronger due to a myriad of factors, including pricing actions, operational and scale efficiencies as well as a favorable product mix... We intend to drive gross margins to the mid-50% level and operating margins to the mid-40% level over the next several years." - On CSBG:
"The customer support business group generated a third consecutive quarter of record revenue at nearly $2.5 billion... Sequentially, the increase was primarily due to record upgrade revenue." - On Supply Chain:
"Our team is doing a phenomenal job, a heroic job, I think, responding to urgent customer requests and so when those do come up, we've been able to meet those needs."
What Changed Since Last Year
- Revenue and margin acceleration: Lam is now guiding to >$8B quarterly revenue and 52% gross margin, both record levels, with YoY growth accelerating.
- NAND upgrade cycle pulled forward: Most of the $40B upgrade cycle is now expected to complete by end of 2027, with greenfield additions to follow.
- Advanced packaging growth revised up: Now expected to grow >70% YoY in 2026, up from >50% earlier in the year.
- Gross margin target raised: Long-term gross margin target increased to mid-50% from 50%.
- China exposure moderating: China now 26% of revenue, down from 34% last quarter, with global multinationals in China offsetting domestic weakness.
