Analysis

Rambus reported record Q3 2026 revenue of $218.3 million, up 22% year over year and above its $210 million to $216 million guidance range. Product revenue reached a record $114.3 million, up 15% quarter over quarter and 22% year over year. Royalties revenue was $77.0 million and contract and other revenue was $27.0 million. Management attributed the product result to strong customer demand.

Profitability advanced on both reported bases. GAAP operating income was $83.6 million and GAAP operating margin was 38 %, versus $63.3 million and 35 % in the prior-year quarter. Non-GAAP operating income was $102.2 million, with a 47 % operating margin, versus $79.2 million and 44 %. GAAP net income was $74.6 million, and non-GAAP net income was $91.7 million. GAAP diluted earnings per share of $0.69 and non-GAAP diluted earnings per share of $0.84 both exceeded the stated guidance range.

Cash generation was a further strength, with a record $102.5 million of cash from operating activities. Cash, cash equivalents, and marketable securities totaled $776.9 million at September 30, 2026, down $48.0 million from June 30, 2026. The company cited $135.4 million of common-stock repurchases and $11.2 million of capital expenditures as uses of cash, partly offset by operating cash generation. Inventory was $87,235 thousand at September 30, 2026, compared with $44,098 thousand at December 31, 2025.

The Q4 outlook calls for revenue of $227 million to $233 million, including product revenue of $127 million to $133 million, royalties revenue of $68 million to $74 million, and contract and other revenue of $26 million to $32 million. Guided GAAP diluted earnings per share is $0.68 to $0.76, while non-GAAP diluted earnings per share is $0.84 to $0.92. Management said it expects an even stronger Q4 performance, but specified that achieving the revenue range requires customer agreements for various product sales and solutions licensing.

The company is positioning its product and IP roadmap around next-generation AI and data center infrastructure. It highlighted expanded offerings including PMIC for LPDDR6 SOCAMM2 and data center-class Root of Trust security IP. The reported period combines higher revenue, expanded operating margin, record operating cash flow and continued repurchases, while Q4 execution remains tied to signing the required customer agreements.

Questions about RMBS earnings dates

When is Rambus's next earnings date?
AlphAI has no confirmed date for RMBS yet. We publish an earnings date only once the company has set it, so this page shows one the day that happens.
Where does the date come from, and why is there no estimate?
A confirmed date comes from the company's own announcement. Many sites fill the gap by adding about 91 days to the last report, but that arithmetic is a guess, and a wrong date costs a reader more than a missing one, so AlphAI shows nothing until the company confirms. Every quarter already on this page is read straight from the SEC filing: an 8-K item 2.02 for US filers, a 6-K earnings release for foreign private issuers.
