Examining Cashflow Against AAON's Earnings

As finance nerds would already know, the accrual ratio from cashflow is a key measure for assessing how well a company's free cash flow (FCF) matches its profit. 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. 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. That's because some academic studies have suggested that high accruals ratios tend to lead to lower profit or less profit growth.

Over the twelve months to December 2024, AAON recorded an accrual ratio of 0.22. 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 US$21m despite its profit of US$168.6m, mentioned above. We saw that FCF was US$49m a year ago though, so AAON has at least been able to generate positive FCF in the past.
