How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Key Terms

gaap, non-gaap, diluted eps, deferred revenue

4 terms

gaap financial

"U.S. GAAP gross margin as a percent of revenue"

GAAP, or Generally Accepted Accounting Principles, are a set of standardized rules and guidelines that companies follow when preparing their financial statements. They ensure consistency, transparency, and comparability across different companies, making it easier for investors to understand and compare financial information accurately. This helps investors make informed decisions based on trustworthy and uniform financial reports.

View in glossary

non-gaap financial

"Non-GAAP gross margin as a percent of revenue"

Non-GAAP refers to financial measures that companies use to show their earnings or performance without including certain expenses or income that are often added back to give a different picture. It matters because it can make a company's results look better or more favorable, but it may also hide important costs, so investors need to look at both GAAP (official rules) and non-GAAP numbers to get a full understanding.

View in glossary

diluted eps financial

"U.S. GAAP diluted EPS of $2.19"

Diluted earnings per share (EPS) shows how much profit a company makes for each share of stock, assuming all possible shares from stock options or convertible securities are used. It provides a more conservative estimate than basic EPS, accounting for potential share increases that could dilute ownership. Investors use diluted EPS to get a clearer picture of a company's true profitability on a per-share basis.

deferred revenue financial

"Deferred revenue at the end of the September 2026 quarter increased"

Cash a company has already received for goods or services it has promised but not yet delivered; it's recorded as a liability because the company still owes that product, service, or future revenue recognition. For investors, deferred revenue signals upcoming work or deliveries that will convert into reported sales over time and affects short-term obligations, cash flow quality, and how quickly a firm can grow recognized revenue—think of it like prepaid subscriptions or gift cards a business must honor later.

Non-GAAP Financial Results

For the September 2026 quarter, non-GAAP gross margin was $4.31 billion, or 52.4% of revenue, non-GAAP operating expenses were $1.00 billion, non-GAAP operating margin was 40.2%, and non-GAAP net income was $2.77 billion, or $2.20 per diluted share.

"With AI driving higher semiconductor demand and greater device complexity, our focus on operational execution helped Lam deliver record revenue, profit, and earnings per share in the September quarter," said Tim Archer, Lam Research's President and Chief Executive Officer. "Our strategic investments in technology inflections and manufacturing capacity are paying off, strengthening our ability to outgrow the wafer fabrication equipment market as the industry expands."

Balance Sheet and Cash Flow Results

Cash, cash equivalents, and restricted cash balances increased to $7.45 billion at the end of the September 2026 quarter compared to $5.60 billion at the end of the June 2026 quarter. The increase was primarily the result of cash generated from operating activities during the quarter partially offset by cash deployed for capital return activities and capital expenditures.

Deferred revenue at the end of the September 2026 quarter increased to $2.66 billion compared to $2.43 billion as of the end of the June 2026 quarter. Lam's deferred revenue balance does not include shipments to customers in Japan, to whom control does not transfer until customer acceptance. Shipments to customers in Japan are classified as inventory at cost until the time of acceptance. The estimated future revenue from shipments to customers in Japan was approximately $468.3 million as of September 27, 2026 and $490.2 million as of June 28, 2026.

The information provided above is only an estimate of what the Company believes is realizable as of the date of this release and does not incorporate the potential impact of any business combinations, asset acquisitions, divestitures, restructuring, balance sheet valuation adjustments, financing arrangements, other investments, or other items that may be completed or realized after the date of this release, except as described below. U.S. GAAP to non-GAAP reconciling items provided include only those items that are known and can be estimated as of the date of this release. Actual results will vary from this model and the variations may be material. Reconciling items included above are as follows:

• Gross margin - amortization related to intangible assets acquired through certain business combinations, $2.7 million.

• Operating margin - amortization related to intangible assets acquired through certain business combinations, $3.0 million.

• Net income per diluted share - amortization related to intangible assets acquired through certain business combinations, $3.0 million; amortization of note discounts, $0.5 million; and associated tax benefit for non-GAAP items ($0.2 million); totaling $3.3 million.

Use of Non-GAAP Financial Results

In addition to U.S. GAAP results, this press release also contains non-GAAP financial results. The Company's non-GAAP results for both the September 2026 and June 2026 quarters exclude amortization related to intangible assets acquired through certain business combinations, the effects of elective deferred compensation-related assets and liabilities, amortization of note discounts, and the net income tax effect of non-GAAP items. The September 2026 quarter also excludes the net income tax effect of a change in tax law, and the June 2026 quarter excludes workforce optimization charges and the related income tax effect.

Management uses non-GAAP gross margin, operating expense, operating income, operating margin, net income, and net income per diluted share to evaluate the Company's operating and financial results. The Company believes the presentation of non-GAAP results is useful to investors for analyzing business trends and comparing performance to prior periods, along with enhancing investors' ability to view the Company's results from management's perspective.
