Coherent Corp.'s (NYSE:COHR) stock was strong after they recently reported robust earnings. We did some analysis and think that investors are missing some details hidden beneath the profit numbers.

In order to understand the potential for per share returns, it is essential to consider how much a company is diluting shareholders. Coherent expanded the number of shares on issue by 26% over the last year. As a result, its net income is now split between a greater number of shares. To talk about net income, without noticing earnings per share, is to be distracted by the big numbers while ignoring the smaller numbers that talk to per share value.

How Is Dilution Impacting Coherent's Earnings Per Share (EPS)?

Coherent was losing money three years ago. And even focusing only on the last twelve months, we don't have a meaningful growth rate because it made a loss a year ago, too. But mathematics aside, it is always good to see when a formerly unprofitable business come good (though we accept profit would have been higher if dilution had not been required). So you can see that the dilution has had a fairly significant impact on shareholders.

If Coherent's EPS can grow over time then that drastically improves the chances of the share price moving in the same direction. But on the other hand, we'd be far less excited to learn profit (but not EPS) was improving. For that reason, you could say that EPS is more important that net income in the long run, assuming the goal is to assess whether a company's share price might grow.

How Do Unusual Items Influence Profit?

Alongside that dilution, it's also important to note that Coherent's profit suffered from unusual items, which reduced profit by US$148m in the last twelve months. 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, after all, that's exactly what the accounting terminology implies. Assuming those unusual expenses don't come up again, we'd therefore expect Coherent to produce a higher profit next year, all else being equal.

Our Take On Coherent's Profit Performance

To sum it all up, Coherent took a hit from unusual items which pushed its profit down; without that, it would have made more money. But unfortunately the dilution means that shareholders now own a smaller proportion of the company (assuming they maintained the same number of shares). That will weigh on earnings per share, even if it is not reflected in net income. Having considered these factors, we don't think Coherent's statutory profits give an overly harsh view of the business. If you'd like to know more about Coherent as a business, it's important to be aware of any risks it's facing.
