A Closer Look At Sinopec Oilfield Service'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). 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.

As a result, a negative accrual ratio is a positive for the company, and a positive accrual ratio is a negative. 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. 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 September 2025, Sinopec Oilfield Service recorded an accrual ratio of -0.12. That indicates that its free cash flow was a fair bit more than its statutory profit. Indeed, in the last twelve months it reported free cash flow of CN¥4.5b, well over the CN¥624.5m it reported in profit. Notably, Sinopec Oilfield Service had negative free cash flow last year, so the CN¥4.5b it produced this year was a welcome improvement.
