Lam Research reported a record $8.22 billion in quarterly revenue on October 21, 2026, for the period ended September 27. Revenue rose 22% sequentially from $6.72 billion and approximately 54% year over year, according to its official earnings release and SEC Form 8-K. The company credited AI-driven demand for more sophisticated semiconductor manufacturing equipment.

Key Takeaways

• Quarterly revenue reached $8.22 billion, up 22% from June 2026.
• New wafer-fabrication systems generated $5.73 billion; support and related revenue contributed $2.49 billion.
• GAAP operating margin reached 40.0%, with diluted earnings of $2.19 per share.
• Lam forecasts December-quarter revenue of $8.6 billion, plus or minus $400 million, while warning of near-term supply constraints.

What the Results Show

The $5.73 billion systems figure includes advanced deposition, plasma etch, cleaning and related fabrication equipment. These tools build intricate transistor structures, multilayer memory and vertical interconnects. Lam’s etch technology guide explains why high-aspect-ratio plasma processing is increasingly important as chip structures become taller and denser.

Why Manufacturing Capacity Matters

Lam expects December-quarter revenue of approximately $8.6 billion, with a $400 million range. During its October 21 investor webcast, management said the outlook would have been higher without certain component supply bottlenecks. It also flagged cleanroom availability as a constraint as chipmakers expand. Those are forward-looking assessments, not guaranteed production or sales.

For practical background, BitcoinVersus.Tech’s plasma-etch equipment lesson, deposition equipment guide, Applied Materials market outlook and semiconductor-machine ranking explain the equipment and processes behind these results.

What Comes Next

Lam’s stronger sales indicate substantial demand for tools used to manufacture AI processors and memory, but quarterly revenue is not a direct measure of global chip output. The December guidance and management’s preliminary 2027 forecasts depend on customer spending, component delivery and factory readiness. An October 23 community discussion offers a separate interpretation; Lam’s filing remains the source for the figures.
