Zooming In On Diffusion Engineers' 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. To get the accrual ratio we first subtract FCF from profit for a period, and then divide that number by the average operating assets for the period. 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. 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".

Diffusion Engineers has an accrual ratio of 0.23 for the year to March 2026. Therefore, we know that it's free cashflow was significantly lower than its statutory profit, which is hardly a good thing. Over the last year it actually had negative free cash flow of ₹182m, in contrast to the aforementioned profit of ₹503.2m. We also note that Diffusion Engineers' free cash flow was actually negative last year as well, so we could understand if shareholders were bothered by its outflow of ₹182m.
