The market wasn't impressed with the soft earnings from Ameresco, Inc. (NYSE:AMRC) recently. We did some analysis, and found that there are some reasons to be cautious about the headline numbers.

An Unusual Tax Situation

Ameresco reported a tax benefit of US$16m, 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. 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. 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. While we think it's good that the company has booked a tax benefit, it does mean that there's every chance the statutory profit will come in a lot higher than it would be if the income was adjusted for one-off factors.

Our Take On Ameresco's Profit Performance

As we have already discussed Ameresco reported that it received a tax benefit, rather than paying tax, in the last year. As a result we don't think its profit result, which includes that tax-boost, is a good guide to its sustainable profit levels. Because of this, we think that it may be that Ameresco's statutory profits are better than its underlying earnings power. 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. So if you'd like to dive deeper into this stock, it's crucial to consider any risks it's facing. For example, we've found that Ameresco has 2 warning signs (1 can't be ignored!) that deserve your attention before going any further with your analysis.

This note has only looked at a single factor that sheds light on the nature of Ameresco's profit. But there is always more to discover if you are capable of focussing your mind on minutiae. Some people consider a high return on equity to be a good sign of a quality business.
