Rambus had $708M of revenue in fiscal 2025, up 27.1% on the year before. Over five years, revenue changed +23.5% a year on average.
Hi! I read Rambusβs latest annual report (fiscal 2025). Here is what stands out:

Rules of thumb on reported numbers. A starting point, not a recommendation.
About these figures. Rambus' filings from 2022 tag a figure of about US$10 million as its depreciation and amortization total, against US$35 million of depreciation alone in 2025, so depreciation and amortization, EBITDA and the ratios built on it are left blank.
Is it selling more, and how much does it keep?
In plain words: Every quarter, companies publish how much they sold and earned. These are the days Rambus did it, and the next one. Share prices often move a lot on those days.

From SEC filings: the results press release (8-K) or, without one, the quarterly or annual report.
KIRA Β· Rambus had $708M of revenue in fiscal 2025, up 27.1% on the year before. Over five years, revenue changed +23.5% a year on average. Its operating margin was 36.8%, up 3.9Β pts: of every 100 in sales, about 37 is left after running the business.
In plain words: Revenue is all the money customers paid. The margins show how many cents of each dollar of sales are left over at each step: after making the product (gross), after running the business (operating) and after everything, tax included (net).

KIRA Β· Free cash flow was $333M in fiscal 2025, 47.1% of revenue.
