How Do Unusual Items Influence Profit?

Importantly, our data indicates that Avantor's profit received a boost of US$355m in unusual items, over the last year. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. When we crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. Which is hardly surprising, given the name. Avantor had a rather significant contribution from unusual items relative to its profit to March 2025. All else being equal, this would likely have the effect of making the statutory profit a poor guide to underlying earnings power.

Our Take On Avantor's Profit Performance

As previously mentioned, Avantor's large boost from unusual items won't be there indefinitely, so its statutory earnings are probably a poor guide to its underlying profitability. For this reason, we think that Avantor's statutory profits may be a bad guide to its underlying earnings power, and might give investors an overly positive impression of the company. The silver lining is that its EPS growth over the last year has been really wonderful, even if it's not a perfect measure. 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. Keep in mind, when it comes to analysing a stock it's worth noting the risks involved.
