Lam Research Lifts 2026 WFE Outlook as AI Demand Strains Fab Capacity

Key Points

• Lam Research raised its 2026 wafer-fabrication equipment spending outlook to the low-$150 billion range from $135 billion-$140 billion, driven by sustained AI demand and expectations for eight to 10 new leading-edge fabs through 2027.
• AI hardware is increasing equipment intensity, while advanced chip designs and packaging are expanding Lam’s addressable market. The company cited growing opportunities in gate-all-around transistors, backside power delivery, advanced packaging and dry-resist technology.
• Lam is accelerating capacity expansion, including a second Malaysia facility, as clean-room availability and supply-chain capacity constrain the industry. The company also expects NAND upgrades to accelerate, while targeting mid-50% gross margins and reporting record customer-support revenue.

Lam Research NASDAQ: LRCX executives said the semiconductor equipment industry remains constrained by available clean-room capacity despite a higher outlook for wafer-fabrication equipment spending, citing sustained artificial intelligence demand and a growing pipeline of new fabs.

Speaking at the Citi Global TMT Conference, Executive Vice President and Chief Financial Officer Doug Bettinger said Lam had raised its view for calendar 2026 wafer-fabrication equipment, or WFE, spending to the low-$150 billion range from an earlier estimate of $135 billion to $140 billion.

“The industry is fundamentally under-supplying demand, and clean room is a constraint,” Bettinger said. He said customers have been able to increase output by using available fab space more efficiently, pulling projects forward and bringing existing clean rooms into production sooner than anticipated.

Bettinger said Lam sees eight to 10 new tier-one fabs coming online through the end of 2027, supporting its expectation that WFE spending will grow next year. He added that the company’s top-down and bottom-up assessments point to continued AI demand as computing shifts from training workloads toward inference and eventually “Physical AI.”

AI hardware raises equipment intensity

Vice President of Investor Relations Ram Ganesh said Lam’s estimate that each $100 billion of AI data-center capital spending could generate roughly $8 billion of WFE demand has increased by $1 billion to $2 billion. He attributed the revision to a combination of higher hardware content, greater capital intensity and increased memory requirements.

Ganesh said Lam has raised its NAND serviceable available market per wafer estimate to 2 times from 1.8 times presented at its analyst day. He also said device complexity has increased relative to the assumptions incorporated in the company’s original model.

Bettinger said Lam is having unusually intensive planning discussions with customers and suppliers to ensure capacity is available. Lam is expanding its manufacturing capabilities, including accelerating work on a second facility in Malaysia and increasing output from existing facilities through denser use of production space.

While supply-chain constraints can emerge because Lam’s tools contain thousands of parts, Bettinger characterized those issues as manageable. He said the company is working to ensure it is not a production bottleneck as customer demand rises.

Foundry, logic and packaging opportunities

Bettinger said Lam’s serviceable available market has expanded more quickly than expected. The company previously projected its addressable market would rise from the low-30% range to the high-30% range of WFE spending; Bettinger said Lam’s market opportunity this year is above the mid-30% range and “probably north of 36%.”

He said the expansion reflects foundry and logic spending as customers transition to gate-all-around transistor architectures. Those architectures require more etch and deposition processes, including selective etch, atomic layer deposition and high-aspect-ratio etching, according to Bettinger.

Lam’s Akara conductor-etch product is performing “extraordinarily well,” Bettinger said, as AI computing increases the value customers place on incremental silicon performance and latency improvements. He also cited products including Vantex and ALTUS Halo as beneficiaries of higher research-and-development investment in recent years.

The company estimates that every 100,000 wafer starts of gate-all-around capacity expands Lam’s serviceable market by $1 billion. Backside power delivery could add another $1 billion per 100,000 wafer starts when it is adopted, Bettinger said.

Advanced packaging is another growth area, with Lam’s advanced-packaging business growing more than 70% this year, according to Bettinger. He said Lam expects to compete organically as the industry moves toward panel-level packaging, leveraging its wafer-level capabilities in through-silicon-via etching and copper electroplating. Lam acquired an Austrian company several years ago that added panel-form-factor capabilities, he said.

Bettinger also said demand for Lam’s Aether dry-resist technology is strong, particularly as high-numerical-aperture lithography adoption develops. He said Lam expects its previously discussed five-year cumulative revenue opportunity of $1.5 billion for dry resist to be higher, though he did not provide a revised figure.

NAND, services and profitability

Ganesh said Lam’s previously disclosed $40 billion NAND upgrade opportunity remains unchanged, but the expected timing has accelerated. The company now expects the transition from sub-200-layer NAND to more than 200 layers to be completed by the end of 2027, compressing a process investors had assumed could take three to five years.

He said NAND spending in 2026 and 2027 should remain primarily conversion-driven, with limited greenfield capacity. If demand remains on its current course, Lam expects more capacity additions could be needed in the second half of 2028 and beyond.

Bettinger said high-bandwidth flash technologies are not yet in volume production, but could be favorable for Lam because of its NAND and through-silicon-via positions.

On profitability, Bettinger noted Lam recently reported and guided to 52% gross margin, which he called the company’s highest level in 20 years. He said Lam sees a path to mid-50% gross margins through new products, its close-to-customer manufacturing strategy, the Malaysia expansion, supply-chain benefits and pricing.

Lam’s customer support business group generated nearly $2.5 billion in revenue in the most recently reported quarter, its third consecutive record, Bettinger said. He cited high industry utilization, strong spare-parts consumption, NAND upgrades and service offerings using cobots, equipment intelligence and data-driven techniques.

Finally, Bettinger said China investment remains active, but China is likely to decline as a percentage of industry revenue over several years because leading-edge DRAM, NAND and foundry investment tied to AI computing is growing faster elsewhere. Ganesh cautioned that China exposure could still vary from quarter to quarter.
