Jabil Inc.'s (NYSE:JBL ) stock didn't jump after it announced some healthy earnings. We think that investors might be worried about some concerning underlying factors.

How Do Unusual Items Influence Profit?

Importantly, our data indicates that Jabil's profit received a boost of US$616m 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. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. Which is hardly surprising, given the name. Jabil had a rather significant contribution from unusual items relative to its profit to May 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 Jabil's Profit Performance

As we discussed above, we think the significant positive unusual item makes Jabil's earnings a poor guide to its underlying profitability. As a result, we think it may well be the case that Jabil'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. The goal of this article has been to assess how well we can rely on the statutory earnings to reflect the company's potential, but there is plenty more to consider. In light of this, if you'd like to do more analysis on the company, it's vital to be informed of the risks involved.
