Highlights

  • Lam Research increased September-quarter revenue 22% QoQ to USD 8.22bn, with higher margins supporting record profit and earnings.
  • Management expects December-quarter revenue of USD 8.6bn at the midpoint, alongside further improvement in the modelled operating margin.
  • A planned global laboratory expansion exceeds USD 3bn over five years and targets substantially more capacity for semiconductor experiments.
  • The board increased its quarterly dividend 27% in August, adding a larger shareholder distribution alongside the research investment programme.

Record operating results are coinciding with a larger research commitment at Lam Research Corporation (NASDAQ:LRCX), a supplier of wafer fabrication equipment and services. Its September quarter delivered higher revenue, margins and earnings as management linked demand to AI-related chip complexity. A planned laboratory expansion aims to accelerate the next generation of process development. Shares closed at USD 237.50, up 3.22%, after the market session ended on 26 October 2026. The company's latest financial performance and its multi-year research plan address different stages of the same equipment development cycle.

September Performance Supports a Higher December Model

Revenue reached USD 8.22bn for the quarter ended 27 September, increasing 22% QoQ. GAAP gross margin was 52.3%, operating margin reached 40.0% and diluted earnings were USD 2.19 per share. Cash, equivalents and restricted cash increased to USD 7.45bn from USD 5.60bn at June's end.

Systems revenue was USD 5.73bn, while customer support and other revenue contributed USD 2.49bn. China represented 35% of quarterly revenue, followed by Korea at 20% and Taiwan at 18%.

For the December quarter, management models revenue of USD 8.6bn, plus or minus USD 400mn, and non-GAAP operating margin of 40.5%, plus or minus one percentage point. The guidance remains an estimate, separate from the completed September results.

Laboratory Expansion Targets Faster Product Development

In August, Lam outlined plans to invest more than USD 3bn over five years in its global research and development laboratory network. The expansion is expected to increase experiment capacity by more than 50%, adding infrastructure across a network spanning the United States, Asia and Europe.

The existing network supports more than one million experiments annually. Specialised facilities address different stages of development, including new chemistries, materials and mechatronics. Lam combines this work with customer collaboration, including facilities close to customers' operations.

The planned investment is intended to shorten the path from early research to equipment deployment in semiconductor factories. Management sees faster experimentation as increasingly relevant as chip architectures adopt different materials and more complex features. The announced spending and capacity gains remain a multi-year programme rather than a completed expansion reflected in one quarter's revenue.

Capital Returns Continue Alongside Technology Spending

The board approved a quarterly dividend increase from USD 0.26 to USD 0.33 per share on 27 August. The USD 0.07 increase represented 27%, establishing a higher declared distribution while the company continues investment in its research infrastructure.

Future dividends remain subject to board review and approval. Lam's equipment and services business includes both new systems used in wafer fabrication and support for customers' installed equipment. Research development supports the former, while services, spares and upgrades form part of the continuing customer relationship.

The current priorities therefore combine execution against near-term equipment demand with laboratory capabilities intended to support future products. Management's December model sets the immediate financial reference, while the proposed research expansion extends over several years. Their different timeframes are central to how the operating and investment programmes fit together.
