Signet Jewelers Limited's (NYSE:SIG ) stock didn't jump after it announced some healthy earnings. We think that investors might be worried about some concerning underlying factors.

An Unusual Tax Situation

Signet Jewelers reported a tax benefit of US$174m, which is well worth noting. This is meaningful because companies usually pay tax rather than receive tax benefits. Of course, prima facie it's great to receive a tax benefit. 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 Signet Jewelers' Profit Performance

Signet Jewelers reported that it received a tax benefit, rather than paid tax, in its last report. Given that sort of benefit is not recurring, a focus on the statutory profit might make the company seem better than it really is. Because of this, we think that it may be that Signet Jewelers' statutory profits are better than its underlying earnings power. 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.
