Zooming In On Saia'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. 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. To quote a 2014 paper by Lewellen and Resutek, "firms with higher accruals tend to be less profitable in the future".

For the year to September 2024, Saia had an accrual ratio of 0.38. As a general rule, that bodes poorly for future profitability. And indeed, during the period the company didn't produce any free cash flow whatsoever. In the last twelve months it actually had negative free cash flow, with an outflow of US$394m despite its profit of US$375.2m, mentioned above. It's worth noting that Saia generated positive FCF of US$116m a year ago, so at least they've done it in the past.

Our Take On Saia's Profit Performance

As we discussed above, we think Saia's earnings were not supported by free cash flow, which might concern some investors. As a result, we think it may well be the case that Saia's underlying earnings power is lower than its statutory profit. Nonetheless, it's still worth noting that its earnings per share have grown at 68% over the last three years. Of course, we've only just scratched the surface when it comes to analysing its earnings; one could also consider margins, forecast growth, and return on investment, among other factors. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks. For example - Saia has 1 warning sign we think you should be aware of.

This note has only looked at a single factor that sheds light on the nature of Saia's profit. But there is always more to discover if you are capable of focussing your mind on minutiae. For example, many people consider a high return on equity as an indication of favorable business economics, while others like to 'follow the money' and search out stocks that insiders are buying.
