An Unusual Tax Situation

We can see that Ameresco received a tax benefit of US$18m. 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, 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.

Our Take On Ameresco's Profit Performance

Ameresco 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 Ameresco's true underlying earnings power is actually less than its statutory profit. But at least holders can take some solace from the 14% EPS growth in the last year. The goal of this article has been to assess how well we can rely on the statutory earnings to reflect the company's potential, but there is plenty more to consider. So if you'd like to dive deeper into this stock, it's crucial to consider any risks it's facing.
