Twin Disc, Incorporated (NASDAQ:TWIN) just reported some strong earnings, and the market reacted accordingly with a healthy uplift in the share price. However, our analysis suggests that shareholders may be missing some factors that indicate the earnings result was not as good as it looked.

An Unusual Tax Situation

Twin Disc reported a tax benefit of US$19m, which is well worth noting. 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. Assuming the tax benefit is not repeated every year, we could see its profitability drop noticeably, all else being equal.

Our Take On Twin Disc's Profit Performance

Twin Disc received a tax benefit in its last reported period, as we have mentioned already. Tax is usually an expense, not a benefit, so we don't think the reported profit number is a particularly good guide to the earning potential of the business. For this reason, we think that Twin Disc's statutory profits may be a bad guide to its underlying earnings power, and might give investors an overly positive impression of the company. But on the bright side, its earnings per share have grown at an extremely impressive rate over the last three years. 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. So while earnings quality is important, it's equally important to consider the risks facing Twin Disc at this point in time. While conducting our analysis, we found that Twin Disc has 1 warning sign and it would be unwise to ignore this.

Today we've zoomed in on a single data point to better understand the nature of Twin Disc's profit. But there are plenty of other ways to inform your opinion of a company. Some people consider a high return on equity to be a good sign of a quality business.
