AAON, Inc.'s( NASDAQ:AAON ) stock showed strength, with investors undeterred by its weak earnings report. Sometimes, shareholders are willing to ignore soft numbers with the hope that they will improve, but our analysis suggests this is unlikely for AAON.
Examining Cashflow Against AAON'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. You could think of the accrual ratio from cashflow as the 'non-FCF profit ratio'.
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. 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.
AAON has an accrual ratio of 0.23 for the year to March 2026. Unfortunately, that means its free cash flow fell significantly short of its reported profits. Even though it reported a profit of US$118.1m, a look at free cash flow indicates it actually burnt through US$164m in the last year. We also note that AAON's free cash flow was actually negative last year as well, so we could understand if shareholders were bothered by its outflow of US$164m.
