Investors were disappointed with FormFactor, Inc.'s (NASDAQ:FORM) earnings, despite the strong profit numbers. We did some digging and found some worrying underlying problems.

How Do Unusual Items Influence Profit?

Importantly, our data indicates that FormFactor's profit received a boost of US$91m 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. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. And, after all, that's exactly what the accounting terminology implies. We can see that FormFactor's positive unusual items were quite significant relative to its profit in the year to September 2024. 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 FormFactor's Profit Performance

As previously mentioned, FormFactor's large boost from unusual items won't be there indefinitely, so its statutory earnings are probably a poor guide to its underlying profitability.

On the bright side, the company showed enough improvement to book a profit this year, after losing money last year. 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.
