An Unusual Tax Situation

Power Integrations reported a tax benefit of US$10m, which is well worth noting. 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! We're sure the company was pleased with its tax benefit. However, the devil in the detail is that these kind of benefits only impact in the year they are booked, and are often one-off in nature. 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.

That might leave you wondering what analysts are forecasting in terms of future profitability. Luckily, you can click here to see an interactive graph depicting future profitability, based on their estimates.

Our Take On Power Integrations' Profit Performance

Power Integrations reported that it received a tax benefit, rather than paid tax, in its last report. As a result we don't think its profit result, which includes that tax-boost, is a good guide to its sustainable profit levels. Therefore, it seems possible to us that Power Integrations' true underlying earnings power is actually less than its statutory profit. In further bad news, its earnings per share decreased in the 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. With this in mind, we wouldn't consider investing in a stock unless we had a thorough understanding of the risks.
