Ameresco (AMRC) Valuation Check After New Nuclear MOU And Illinois Renewable Gas Milestone

Listen to the news

Ameresco (AMRC) is back in focus after two project updates, including an MOU with NANO Nuclear Energy on modular micro reactors and a new renewable natural gas facility now operating in Illinois.

See our latest analysis for Ameresco.

The recent MOU around modular micro reactors and the new Illinois renewable natural gas facility arrive as momentum rebuilds, with a 1 month share price return of 11.88% and a year to date share price return of 8.05%. However, the 3 year total shareholder return of 46.33% and 5 year total shareholder return of 43.94% remain weak compared with the 43.77% total shareholder return over the last 12 months.

If this kind of clean energy project news has your attention, it could be a good moment to see what else is setting up in high growth tech and AI stocks.

With shares up in the short term but longer term returns still weak, and with the stock trading below analyst targets and some intrinsic value estimates, is Ameresco quietly sitting at a discount, or is the market already pricing in future growth?

Most Popular Narrative: 24.3% Undervalued

At a last close of US$33.14 versus a narrative fair value of US$43.78, Ameresco is framed as trading at a sizable discount, with that gap tied directly to long term growth and margin assumptions that extend beyond the latest project headlines.

Analysts have modestly raised their price target on Ameresco, lifting the implied fair value by about 5 percent to approximately $43.78 per share, citing slightly higher long term growth expectations, a marginally stronger profit outlook, and a richer future earnings multiple.

Read the complete narrative.

Curious what kind of revenue path, profitability lift, and future earnings multiple need to align in order to reach that valuation gap? The full narrative lays out those assumptions in detail.

Result: Fair Value of $43.78 (UNDERVALUED)

However, this hinges on supply chain reliability and stable clean energy policy, because equipment delays or incentive cuts could quickly challenge those long term earnings assumptions.

Another Way To Look At The Price

That 24.3% “undervalued” narrative sits alongside a very different message from simple earnings multiples. Ameresco trades on a P/E of 27.8x, richer than its peer average of 23.4x, yet below the industry’s 36.1x and our fair ratio estimate of 39.6x. So is this a cushion or a warning sign?
