Last week's profit announcement from Summit Midstream Corporation (NYSE:SMC) was underwhelming for investors, despite headline numbers being robust. We did some digging and found some worrying underlying problems.

How Do Unusual Items Influence Profit?

Importantly, our data indicates that Summit Midstream's profit received a boost of US$126m in unusual items, over the last year. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. 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'. Summit Midstream had a rather significant contribution from unusual items relative to its profit to June 2024. As a result, we can surmise that the unusual items are making its statutory profit significantly stronger than it would otherwise be.
