• Investors may be wondering whether Ameresco at around US$27.74 still offers value after a strong run, or whether most of the opportunity is already reflected in the price.
• The stock has returned 3.7% over the last week and month, while year to date it is down 9.6%. The 1 year return sits at 155.4%, with 3 year and 5 year returns at 38.2% and 42.3% declines respectively. This combination can leave the current valuation looking quite mixed.
• Recent coverage has focused on Ameresco's position in energy efficiency and clean energy solutions, as well as contract wins and project announcements that help frame expectations for future cash flows. This context helps explain why the market has been reassessing both the upside potential and the risks around the stock price.
• Ameresco currently has a valuation score of 4 out of 6. The rest of this article will walk through what that means using different valuation approaches, then conclude with a broader way of thinking about value that can sit alongside the numbers.

Approach 1: Ameresco Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model projects a company’s future cash flows and then discounts them back to today, aiming to estimate what the business could be worth in present dollar terms.

For Ameresco, the model used is a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is a loss of about $592.7 million, so the valuation relies heavily on projections rather than recent cash generation. Analyst inputs and extrapolations point to free cash flow reaching about $182 million in 2030, with intermediate years stepping up from $16.3 million in 2026 to $173 million in 2029, all in dollar terms and then discounted back to today.

Pulling these projected cash flows together gives an estimated intrinsic value of about $29.39 per share, compared with the current share price of roughly $27.74. That implies the stock is around 5.6% below the DCF estimate, which falls into a “close enough” range rather than suggesting it is particularly cheap or expensive.

Result: ABOUT RIGHT

Ameresco is fairly valued according to our Discounted Cash Flow (DCF), but this can change at a moment's notice. Track the value in your watchlist or portfolio and be alerted on when to act.

Approach 2: Ameresco Price vs Earnings

For a profitable company, the P/E ratio is a straightforward way to think about what you are paying for each dollar of current earnings. It ties the share price directly to the business’s ability to generate profit, which many investors use as a quick reality check on valuation.

What counts as a “normal” P/E depends on how the market views a company’s growth prospects and risk. Higher expected growth or lower perceived risk can justify a higher P/E, while slower growth or higher risk usually point to a lower, more cautious multiple.

Ameresco currently trades on a P/E of about 33.21x. That is below the Construction industry average of roughly 43.07x and also below the peer group average of around 98.68x. Simply Wall St’s Fair Ratio for Ameresco is 38.36x, which is its proprietary view of what the P/E could be given factors such as earnings growth, profit margins, industry, market cap and risk profile. This Fair Ratio can be more tailored than a simple peer or industry comparison because it tries to adjust for the company’s own characteristics. With the current P/E sitting below the Fair Ratio, Ameresco screens as undervalued on this metric.

Result: UNDERVALUED
