Ameresco (AMRC) has just finished the first phase of a multi year manhole rehabilitation project with the City of Mesquite, Texas, refurbishing more than 190 aging structures in the city’s wastewater system.

Ameresco’s recent wastewater win and investor conference appearances come as momentum in the stock has picked up, with a 30 day share price return of 31.84% and a 1 year total shareholder return of 161.1%, even though the 3 and 5 year total shareholder returns are still negative.

With Ameresco sharing strong short term share price gains and trading at a discount of 19% to its analyst price target, the key question for you is whether there is still an opportunity here or if the market is already pricing in future growth.

Most Popular Narrative: 16% Undervalued

Ameresco's most followed narrative pegs fair value at $42.60, above the last close of $35.98, which puts the recent rally into clearer context.

Sharply rising utility rates and escalating grid instability are prompting more public and private clients to pursue long-term energy infrastructure, distributed generation, and microgrid projects. These are areas where Ameresco's project backlog and pipeline are rapidly growing, indicating upside for future revenues and gross margins as these higher-value projects convert.

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 via increased operating leverage.

Want to see what is actually baked into that fair value? The narrative leans heavily on faster earnings growth, fatter margins, and a richer future earnings multiple.

Putting it together, the narrative uses a 12.33% discount rate and assumes higher future earnings power to arrive at a fair value of $42.60 per share, which is above both the current $35.98 price and the $42.90 analyst price target, implying some upside according to that framework.

Result: Fair Value of $42.60 (UNDERVALUED)

However, this hinges on timely execution, as supply chain snags and shifting clean energy policy could delay projects, pressure margins, and weaken those upbeat assumptions.

Another View: Market Ratios Tell A Tougher Story

While the narrative framework points to a fair value of $42.60, the market’s current P/E of 60.8x is higher than both the estimated fair ratio of 52.2x and the US Construction industry at 51.6x. This suggests investors are already paying a premium. Is that level of optimism something you are comfortable underwriting?
