Frequently Asked Questions

Common questions about this slide and the underlying presentation content.

What does the Lam Research September quarter 2026 earnings presentation cover?

The 26-page deck, dated October 21, 2026, covers Lam's results for the September 2026 quarter (fiscal Q1 2027). It includes a company snapshot, a CEO business review on NAND, foundry/logic, DRAM, advanced packaging and the Customer Support Business Group, then CFO financial results, December 2026 quarter guidance, Q&A, five GAAP-to-non-GAAP reconciliation appendices and a glossary.

What were Lam Research's key numbers for the September 2026 quarter?

Revenue was a record $8.22B ($8,219M), up from $6.72B in the June quarter. Non-GAAP gross margin was 52.4%, non-GAAP operating margin was 40.2% (above 40% for the first time), non-GAAP EPS was $2.20 and GAAP EPS was $2.19. CSBG revenue was $2.49B, and quarterly free cash flow was about $3.24B.

What guidance did Lam Research give for the December 2026 quarter?

Lam guided to revenue of $8.60B +/- $400M, non-GAAP gross margin of 52.5% +/- 1%, non-GAAP operating margin of 40.5% +/- 1%, and non-GAAP EPS of $2.33 +/- $0.15, based on about 1.253 billion diluted shares. The deck puts WFE at a mid-$150B range for CY26 and a preliminary >$200B for CY27.

What is the design style of this deck?

It uses a dark navy background with mint-teal accents, elegant serif headlines paired with clean sans-serif body text, and a small dotted-grid motif in the top-right corner. Cover and divider slides use dramatic blue light-streak photography. Content slides use translucent cards with teal top rules, oversized serif KPI numerals, pie charts in a teal-yellow-orange palette, and tables whose current-quarter column is filled solid mint-teal.

Can I get an editable PPTX version of this presentation?

Yes. This page offers the original PDF and an editable PPTX download. Lam Research publishes the deck as a PDF; the PPTX is a conversion of that PDF, so every slide's text, charts and layout can be edited in PowerPoint, Keynote or Google Slides. You can also use the Create Slides Like This flow on 2Slides to generate a new deck in the same style with your own content.

How can I adapt this deck structure for my own earnings presentation?

Follow its flow: cover, safe-harbor statement, company snapshot, a CEO section (record highlights in three cards, market and technology slides, closing thesis), a CFO section (KPI highlight cards, revenue mix pie charts, a quarter-over-quarter results table, capital return metrics, a guidance slide), then Q&A, reconciliation appendices and a glossary. Keep one accent color for the current period so the latest numbers stand out, and only use numbers your filings support.

How was Lam's September 2026 quarter revenue split by segment and region?

Systems revenue by market segment was Foundry 46%, Memory 46% (NVM 26% and DRAM 20%) and Logic/Other 8%. Total revenue by region was China 35%, Korea 20%, Taiwan 18%, Japan 9%, US 8%, Southeast Asia 6% and Europe 4%.

Where is the original Lam Research presentation from?

It comes from Lam Research's investor relations website, which posts quarterly earnings materials on its quarterly results page (investor.lamresearch.com/quarterly-results).
