Ameresco (AMRC) has been drawing fresh attention after recent share price swings, with the stock down about 18% over the past month but showing a gain over the past 3 months.

Set against a 1 year total shareholder return of 69.16% but a 5 year total shareholder return that is down 56.93%, Ameresco’s recent 30 day share price decline of 17.80% and year to date share price decline of 11.48% suggest momentum has cooled after a strong rebound.

With Ameresco stock trading at $27.15 and sitting at a sizeable discount to the average analyst price target of $42.90, the key question is whether this gap reflects undervaluation or if markets already factor in future growth.

Most Popular Narrative: 36.3% Undervalued

With Ameresco shares at $27.15 versus a narrative fair value of $42.60, the current setup focuses attention on how future earnings power could close that gap.

Growing recurring O&M contract revenue and a rising base of operating energy assets (now at 750MW) are providing Ameresco with more predictable, higher-margin income, supporting greater financial stability and margin expansion over time. Investing in new technologies (e.g., small modular reactors), deeper penetration into C&I/data center markets, and disciplined project screening are enabling Ameresco to access emerging, higher-margin opportunities while reducing execution risk and enhancing forward visibility for earnings growth.

Want to see what sits behind that earnings power story? The narrative hinges on specific revenue growth, margin uplift, and a future earnings multiple that has been carefully modelled but not yet fully unpacked here.

Result: Fair Value of $42.60 (UNDERVALUED)

However, for Ameresco the story can change quickly if supply chain setbacks delay that US$5.0b project backlog or if policy support for clean energy is scaled back.

Another View: What the SWS DCF Model Says About Ameresco

The earlier narrative framed Ameresco stock as undervalued relative to analyst targets and a fair value of $42.60, but the SWS DCF model lands in a different place. On that approach, Ameresco, at $27.15, trades above an estimated future cash flow value of $20.83, so it screens as overvalued instead.

That gap between an earnings based fair value and a more conservative cash flow view leaves a real question for you: which story do you trust more when cash is the reference point rather than multiples and narratives about future margins?
