GATX Corporation (NYSE:GATX) announced strong profits, but the stock was stagnant. We did some digging, and we found some concerning factors in the details.

How Do Unusual Items Influence Profit?

Importantly, our data indicates that GATX's profit received a boost of US$119m in unusual items, over the last year. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. And that's as you'd expect, given these boosts are described as 'unusual'. We can see that GATX's positive unusual items were quite significant relative to its profit in the year to March 2024. As a result, we can surmise that the unusual items are making its statutory profit significantly stronger than it would otherwise be.

Our Take On GATX's Profit Performance

As previously mentioned, GATX's large boost from unusual items won't be there indefinitely, so its statutory earnings are probably a poor guide to its underlying profitability. As a result, we think it may well be the case that GATX's underlying earnings power is lower than its statutory profit. But the good news is that its EPS growth over the last three years has been very impressive. At the end of the day, it's essential to consider more than just the factors above, if you want to understand the company properly.
