Frequently asked questions
Is RMBS growing its revenue and profit?
Over the past 5 years, Rambus's revenue has grown 23.5% per year. These are computed facts, not advice.
How much debt does RMBS have?
As of FY2025, Rambus reported — of total debt against $183M of cash; operating income covered interest expense 190×.
What is RMBS's profit margin?
In FY2025, gross margin was 79.6%, operating margin 36.8%, and net margin 32.6%.
What is RMBS's P/E ratio?
Rambus's P/E (TTM) is 33.84 as of the 2026-11-02 close — market cap ÷ net income over the trailing twelve months where four consecutive quarters are reported, otherwise the latest fiscal year, the same figure as on the RMBS stock page. The valuation chart above sets each month-end's price against the latest annual net income instead, so its latest point (about 39.0× as of Nov '26) can differ. These are computed facts, not advice.
Where does this data come from?
All figures are extracted from the company’s SEC EDGAR/XBRL filings — 10-K annual reports and 10-Q quarterly reports (use the Annual / Quarterly toggle). Quarterly figures are derived from the as-filed statements (year-to-date amounts are differenced into discrete quarters). Growth rates and ratios are computed by tradmap; nothing here is investment advice.

growth rates, valuation multiples & ratios computed by tradmap. Valuation uses each month-end price
against the latest annual filing. Informational only — not investment advice.
