Despite posting healthy earnings, Rambus Inc.'s (NASDAQ:RMBS ) stock has been quite weak. We have done some analysis, and found some encouraging factors that we believe the shareholders should consider.

Zooming In On Rambus' Earnings

In high finance, the key ratio used to measure how well a company converts reported profits into free cash flow (FCF) is the accrual ratio (from cashflow). In plain english, this ratio subtracts FCF from net profit, and divides that number by the company's average operating assets over that period. This ratio tells us how much of a company's profit is not backed by free cashflow.

As a result, a negative accrual ratio is a positive for the company, and a positive accrual ratio is a negative. While it's not a problem to have a positive accrual ratio, indicating a certain level of non-cash profits, a high accrual ratio is arguably a bad thing, because it indicates paper profits are not matched by cash flow. To quote a 2014 paper by Lewellen and Resutek, "firms with higher accruals tend to be less profitable in the future".

For the year to March 2026, Rambus had an accrual ratio of -0.17. That implies it has very good cash conversion, and that its earnings in the last year actually significantly understate its free cash flow. To wit, it produced free cash flow of US$335m during the period, dwarfing its reported profit of US$230.0m. Rambus' free cash flow improved over the last year, which is generally good to see.
