ICU Medical, Inc. (NASDAQ:ICUI) just released a solid earnings report, and the stock displayed some strength. While the profit numbers were good, our analysis has found some concerning factors that shareholders should be aware of.

The Impact Of Unusual Items On Profit

To properly understand ICU Medical's profit results, we need to consider the US$26m 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. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. 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 ICU Medical to produce a higher profit next year, all else being equal.

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that ICU Medical received a tax benefit of US$37m. This is of course a bit out of the ordinary, given it is more common for companies to be paying tax than receiving tax benefits! The receipt of a tax benefit is obviously a good thing, on its own. And given that it lost money last year, it seems possible that the benefit is evidence that it now expects to find value in its past tax losses. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal. So while we think it's great to receive a tax benefit, it does tend to imply an increased risk that the statutory profit overstates the sustainable earnings power of the business.

Our Take On ICU Medical's Profit Performance

In the last year ICU Medical received a tax benefit, which boosted its profit in a way that might not be much more sustainable than turning prime farmland into gas fields. But on the other hand, it also saw an unusual item depress its profit. Given the contrasting considerations, we don't have a strong view as to whether ICU Medical's profits are an apt reflection of its underlying potential for profit. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks.
