- Wafer fabrication equipment spending is forecast at $140 billion in 2026
Key Takeaways:

Lam Research is on track to push its gross margin above 50% for the first time, driven by AI-fueled demand for the advanced etch and deposition tools used in high-bandwidth memory and AI processor production.
Lam Research Corp. guided for a record 50.5% non-GAAP gross margin in the fiscal fourth quarter, as AI-driven demand for advanced memory and packaging tools improves its product mix.
"Strong demand for advanced memory, foundry and packaging equipment is improving the product mix and allowing Lam Research to generate higher returns from its product portfolio," the company said in its Q3 earnings release.
In the third quarter ended March 29, Lam reported revenue of $5.84 billion, up 24% from a year earlier, and non-GAAP earnings per share of $1.47, a 41% increase. Gross margin reached 49.9%, up from 49.7% in the prior quarter and 49% a year ago. The company also delivered a 35% non-GAAP operating margin.
The margin milestone signals that semiconductor equipment makers are capturing more value from the AI infrastructure buildout. Lam expects wafer fabrication equipment spending to reach about $140 billion this year, with advanced packaging revenue rising more than 50% in calendar 2026 as chipmakers invest in complex packaging technologies for AI processors.
KLA Corp., which focuses on process control and inspection, has maintained a non-GAAP gross margin above 60% over the past several quarters, reflecting its strong exposure to advanced logic and memory manufacturing. Applied Materials Inc. reported Semiconductor Systems revenue of $5.97 billion in its most recent quarter, supported by DRAM and advanced packaging demand. Both companies, along with Lam, have benefited from rising AI and memory spending as chipmakers race to expand capacity for high-bandwidth memory and AI accelerator production.
If Lam delivers on its Q4 guidance, it would mark the first time the company's gross margin has crossed the 50% threshold, a level that could support higher earnings power and valuation. The company's non-GAAP operating margin of 35% in Q3 already reflects strong cost discipline. With revenue projected at $6.6 billion in Q4, each 100 basis points of margin expansion adds roughly $66 million to operating profit. Lam shares have gained about 154% in the first half of fiscal 2026, reflecting investor optimism around AI-driven equipment demand.
