Most Popular Narrative: 12% Overvalued

With Ameresco closing at $41.55 and the narrative setting fair value at $37.11, the stock price sits notably above the consensus valuation. This gap is fueling debate over whether optimism has run ahead of the underlying fundamentals.

Expanded government incentives for clean energy and storage (including ITCs and the Inflation Reduction Act) have allowed Ameresco to monetize new projects more quickly and enhance project economics. This has improved both revenue predictability and net margins through increased operating leverage.

Another View: How Does Market Pricing Stack Up?

Looking at Ameresco through the lens of price-to-earnings, the market is valuing shares at 35.3 times earnings, which is essentially in line with peers and the US Construction industry average of 35.8. However, this is well below our calculated fair ratio of 52.3. This narrower gap suggests a more balanced risk profile, but also means upside could be limited unless the market re-rates. Does this close pricing leave the stock exposed to swings in sentiment?
