Despite posting some strong earnings, the market for Diamond Power Infrastructure Limited’s (NSE:DIACABS) stock hasn’t moved much. Our analysis suggests that this might be because shareholders have noticed some concerning underlying factors.
A Closer Look At Diamond Power Infrastructure’s 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.
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. Notably, there is some academic evidence that suggests that a high accrual ratio is a bad sign for near-term profits, generally speaking.
Diamond Power Infrastructure has an accrual ratio of 0.21 for the year to September 2025. Unfortunately, that means its free cash flow fell significantly short of its reported profits. In the last twelve months it actually had negative free cash flow, with an outflow of ₹2.7b despite its profit of ₹617.7m, mentioned above. We saw that FCF was ₹80m a year ago though, so Diamond Power Infrastructure has at least been able to generate positive FCF in the past.
