FRAMINGHAM, MA – May 4, 2026 – Ameresco, Inc. (NYSE:AMRC), a leading energy infrastructure solutions provider, today announced financial results for the first quarter ended March 31, 2026. The Company also furnished supplemental information in conjunction with this press release in a Current Report on Form 8-K. The supplemental information, which includes Non-GAAP financial measures, has been posted to the “Investors” section of the Company’s website at www.ameresco.com. Reconciliations of Non-GAAP measures to the appropriate GAAP measures are included herein. All financial result comparisons made are against the prior year period unless otherwise noted.

CEO George Sakellaris commented, “The first quarter represented a solid start to the year, with revenue growth of 14% despite adverse weather conditions. During the quarter we secured over half a billion dollars in new project awards, driving 20% growth in our Awarded Backlog which now stands at almost $2.8 billion.

“Our customers are navigating a convergence of rising energy costs, rapidly increasing demand, and an imperative for highly resilient energy systems. Against this backdrop, we are experiencing record levels of business development activity, with especially strong demand



coming from our Federal government customers. Ameresco’s diversified mix of building efficiency and energy infrastructure Project offerings together with our Energy Asset solutions and O&M capabilities puts us in a unique position to address these complex challenges as a go-to, comprehensive solutions provider.”

“In a separate release today, we announced the signing of an agreement with HASI for an important $400 million strategic investment in our biofuels business, creating a newly formed joint venture named Neogenyx Fuels. Ameresco has been a leader in the biofuels industry for the last twenty-five years, turning the beneficial use of biogas into a reliable low-carbon fuel source,” said George Sakellaris, Chief Executive Officer of Ameresco. “When completed, this transaction will enable us to monetize a portion of the $1.8 billion enterprise value that we have created in our biogas business, while allowing us to accelerate the future growth of this platform."

(1) Net Income represents net income attributable to common shareholders.
(2) Numbers in table may not sum due to rounding.

Total revenue was $401.5 million, up 14% year over year, driven by strong performances in Projects and O&M. Project revenue increased 16% to $290.5 million, reflecting solid execution across Federal and key geographies in both Building Efficiency and Energy Infrastructure solutions. Energy Asset revenue grew 7% to $60.7 million, supported by continued expansion of our operating asset portfolio, more than offsetting the impact of adverse weather conditions at several RNG facilities. O&M revenue increased 22%, driven by the continued additions of new long-term contracts. Gross margin of 14% reflects the impact of adverse weather at certain RNG sites and project mix.

Net interest and other expenses was $27.8 million, reflecting an increase year over year, primarily driven by $1.8 million of non-cash mark-to-market adjustments on non-hedged derivatives and $0.9 million of foreign exchange losses.

The effective tax rate was approximately 18% in Q1, compared to a (27)% benefit in the prior year, reflecting our decision to monetize certain investment tax credits through third-party sales. Net loss attributable to common shareholders was $18.3 million or $(0.35) per diluted share, with



Non-GAAP loss per share of $(0.33). Adjusted EBITDA of $40.5 million was in line with the Company’s expectations.

Summary and Outlook
“Ameresco is off to a solid start this year, against a favorable backdrop of strong secular trends. We made several important organizational changes in the first quarter that are designed to enhance our ability to execute more effectively and better profit from the tremendous opportunities on the horizon,” concluded CEO George Sakellaris.

Based on our strong start to the year, we would have reaffirmed our original 2026 guidance. In anticipation of the closing of the Neogenyx Fuels transaction, however, we are updating our full-year guidance to reflect the expected impact on our reported results.  Importantly, this update is driven by the structure of the transaction and does not change our underlying operating expectations.

Given the structure of the transaction, we plan to consolidate Neogenyx Fuels, and therefore our revenue guidance remains unchanged. 30% of Neogenyx Fuel's net income will be attributable to HASI and reflected as income attributable to non-controlling interest. Consistent with this, our reported Adjusted EBITDA, as well as our operating assets and assets in development metrics will reflect our 70% ownership.

The company continues to anticipate placing approximately 100-120 MWe of total energy assets in service, including 2 RNG plants. Expected capex is $300 million to $350 million, the majority of which is expected to be funded with a combination of energy asset debt, HASI's investment, tax equity and tax credit sales.  

The revenue cadence for the remainder of the year is expected to follow our historical seasonal pattern, with results weighted toward the second half. We expect the second half to contribute approximately 60% of total 2026 revenue, consistent with recent-year performance.

For the second quarter, with the expectation that the Neogenyx Fuels transaction will close, we expect Adjusted EBITDA of $58 million to $62 million and Non‑GAAP EPS of $0.18 to $0.23.

Exhibit A: Non-GAAP Financial Measures
We use the Non-GAAP financial measures defined and discussed below to provide investors and others with useful supplemental information to our financial results prepared in accordance with GAAP. These Non-GAAP financial measures should not be considered as an alternative to any measure of financial performance calculated and presented in accordance with GAAP. For a reconciliation of these Non-GAAP measures to the most directly comparable financial measures prepared in accordance with GAAP, please see Non-GAAP Financial Measures and Non-GAAP Financial Guidance in the tables above.

We understand that, although measures similar to these Non-GAAP financial measures are frequently used by investors and securities analysts in their evaluation of companies, they have limitations as analytical tools, and investors should not consider them in isolation or as a substitute for the most directly comparable GAAP financial measures or an analysis of our results of operations as reported under GAAP. To properly and prudently evaluate our business, we encourage investors to review our GAAP financial statements included above, and not to rely on any single financial measure to evaluate our business.

Adjusted EBITDA and Adjusted EBITDA Margin
We define adjusted EBITDA as net income attributable to common shareholders, including impact from redeemable non-controlling interests, before income tax (benefit) provision, other expenses net, depreciation, amortization of intangible assets, accretion of asset retirement obligations, stock-based compensation expense, energy asset and goodwill impairment,



contingent consideration, restructuring and other charges, gain or loss on sale of equity investment, and gain or loss upon deconsolidation of a variable interest entity. We believe adjusted EBITDA is useful to investors in evaluating our operating performance for the following reasons: adjusted EBITDA and similar Non-GAAP measures are widely used by investors to measure a company's operating performance without regard to items that can vary substantially from company to company depending upon financing and accounting methods, book values of assets, capital structures and the methods by which assets were acquired; securities analysts often use adjusted EBITDA and similar Non-GAAP measures as supplemental measures to evaluate the overall operating performance of companies; and by comparing our adjusted EBITDA in different historical periods, investors can evaluate our operating results without the additional variations of depreciation and amortization expense, accretion of asset retirement obligations, stock-based compensation expense, impact from redeemable non-controlling interests, contingent consideration, restructuring and asset impairment charges. We define adjusted EBITDA margin as adjusted EBITDA stated as a percentage of revenue.

Our management uses adjusted EBITDA and adjusted EBITDA margin as measures of operating performance, because they do not include the impact of items that we do not consider indicative of our core operating performance; for planning purposes, including the preparation of our annual operating budget; to allocate resources to enhance the financial performance of the business; to evaluate the effectiveness of our business strategies; and in communications with the board of directors and investors concerning our financial performance.

Non-GAAP Net Income and EPS
We define Non-GAAP net income and earnings per share (EPS) to exclude certain discrete items that management does not consider representative of our ongoing operations, including energy asset and goodwill impairment, contingent consideration, restructuring and other charges, impact from redeemable non-controlling interest, gain or loss on sale of equity investment, and gain or loss upon deconsolidation of a variable interest entity. We consider Non-GAAP net income and Non-GAAP EPS to be important indicators of our operational strength and performance of our business because they eliminate the effects of events that are not part of the Company's core operations.

Non-GAAP Adjusted Cash from Operations
We define Non-GAAP adjusted cash from operations as cash flows from operating activities plus proceeds from ITC sales and proceeds from Federal ESPC projects. Cash received in payment of ITC sales are, as of our fiscal year 2025, treated as investing activities under GAAP. Federal ESPC projects are treated as financing cash flows under GAAP. These cash flows, however, correspond to benefits generated by the underlying assets and projects. Thus, we believe that adjusting operating cash flow to include the cash generated from ITC sales and by our Federal ESPC projects provides investors with a useful measure for evaluating the cash generating ability of our core operating business. Our management uses Non-GAAP adjusted cash from operations as a measure of liquidity because it captures all sources of cash associated with our operations.
