Despite posting some strong earnings, the market for D. I. System Co., Ltd.'s (TSE:4421) stock hasn't moved much. We did some digging, and we found some concerning factors in the details.
A Closer Look At D. I. System'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. This ratio tells us how much of a company's profit is not backed by free cashflow.
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. That is not intended to imply we should worry about a positive accrual ratio, but it's worth noting where the accrual ratio is rather high. 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 2025, D. I. System had an accrual ratio of 0.38. 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. Indeed, in the last twelve months it reported free cash flow of JP¥43m, which is significantly less than its profit of JP¥238.0m. D. I. System's free cash flow actually declined over the last year, but it may bounce back next year, since free cash flow is often more volatile than accounting profits. One positive for D. I. System shareholders is that it's accrual ratio was significantly better last year, providing reason to believe that it may return to stronger cash conversion in the future. Shareholders should look for improved cashflow relative to profit in the current year, if that is indeed the case.

Our Take On D. I. System's Profit Performance
As we have made quite clear, we're a bit worried that D. I. System didn't back up the last year's profit with free cashflow. For this reason, we think that D. I.
