The latest earnings release from NCS Multistage Holdings, Inc. (NASDAQ:NCSM ) disappointed investors. We did some digging and found some underlying numbers that are worrying.

The Impact Of Unusual Items On Profit

To properly understand NCS Multistage Holdings' profit results, we need to consider the US$1.2m gain attributed to unusual items. 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'. Assuming those unusual items don't show up again in the current year, we'd thus expect profit to be weaker next year (in the absence of business growth, that is).

An Unusual Tax Situation

Having already discussed the impact of the unusual items, we should also note that NCS Multistage Holdings received a tax benefit of US$9.1m. It's always a bit noteworthy when a company is paid by the tax man, rather than paying the tax man. The receipt of a tax benefit is obviously a good thing, on its own. However, our data indicates that tax benefits can temporarily boost statutory profit in the year it is booked, but subsequently profit may fall back. In the likely event the tax benefit is not repeated, we'd expect to see its statutory profit levels drop, at least in the absence of strong growth. 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 NCS Multistage Holdings' Profit Performance

In its last report NCS Multistage Holdings received a tax benefit which might make its profit look better than it really is on a underlying level. Furthermore, it also benefitted from a positive unusual item, which boosted the profit result even higher. Considering all this we'd argue NCS Multistage Holdings' profits probably give an overly generous impression of its sustainable level of profitability. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks.
