Examining Cashflow Against InterDigital's Earnings

Many investors haven't heard of the accrual ratio from cashflow, but it is actually a useful measure of how well a company's profit is backed up by free cash flow (FCF) during a given period. The accrual ratio subtracts the FCF from the profit for a given period, and divides the result by the average operating assets of the company over that time. The ratio shows us how much a company's profit exceeds its FCF.

Therefore, it's actually considered a good thing when a company has a negative accrual ratio, but a bad thing if its accrual ratio is positive. While having an accrual ratio above zero is of little concern, we do think it's worth noting when a company has a relatively high accrual ratio. Notably, there is some academic evidence that suggests that a high accrual ratio is a bad sign for near-term profits, generally speaking.

Over the twelve months to June 2025, InterDigital recorded an accrual ratio of 0.37. That means it didn't generate anywhere near enough free cash flow to match its profit. As a general rule, that bodes poorly for future profitability. In fact, it had free cash flow of US$274m in the last year, which was a lot less than its statutory profit of US$463.5m. We note, however, that InterDigital grew its free cash flow over the last year.

Our Take On InterDigital's Profit Performance

As we have made quite clear, we're a bit worried that InterDigital didn't back up the last year's profit with free cashflow. As a result, we think it may well be the case that InterDigital's underlying earnings power is lower than its statutory profit. But on the bright side, its earnings per share have grown at an extremely impressive rate over the last three years. At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly. Keep in mind, when it comes to analysing a stock it's worth noting the risks involved.
