How Do Unusual Items Influence Profit?

To properly understand Proto Labs' profit results, we need to consider the US$5.6m expense attributed to unusual items. It's never great to see unusual items costing the company profits, but on the upside, things might improve sooner rather than later. We looked at thousands of listed companies and found that unusual items are very often one-off in nature. And that's hardly a surprise given these line items are considered unusual. Assuming those unusual expenses don't come up again, we'd therefore expect Proto Labs to produce a higher profit next year, all else being equal.
