A Closer Look At Iluka Resources' Earnings

One key financial ratio used to measure how well a company converts its profit to free cash flow (FCF) is the accrual ratio. In plain english, this ratio subtracts FCF from net profit, and divides that number by the company's average operating assets over that period. The ratio shows us how much a company's profit exceeds its FCF.

As a result, a negative accrual ratio is a positive for the company, and a positive accrual ratio is a negative. 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 2024, Iluka Resources recorded an accrual ratio of 0.24. Therefore, we know that it's free cashflow was significantly lower than its statutory profit, which is hardly a good thing. In the last twelve months it actually had negative free cash flow, with an outflow of AU$187m despite its profit of AU$272.5m, mentioned above. It's worth noting that Iluka Resources generated positive FCF of AU$32m a year ago, so at least they've done it in the past.
