Ameresco Reports First Quarter 2026 Financial Results

FRAMINGHAM, Mass. — 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.”

First Quarter Financial Results
(All financial result comparisons made are against the prior year period unless otherwise noted.)

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.

Project and Asset Highlights

Balance Sheet and Cash Flow Metrics

The Company ended the first quarter with $104.0 million in unrestricted cash. Total corporate debt, including subordinated debt, term loans and borrowings under our revolving line of credit, increased to $383.1 million, supporting working capital needs associated with the continued growth of our project and energy asset businesses.

During the quarter the Company executed approximately $149.5 million of new financing commitments. Energy Asset Debt totaled $1.6 billion representing an Energy Debt Advance rate of 73% of Energy Asset Book Value. Non-GAAP Adjusted Cash from Operations for the quarter was $62.0 million, with an 8-quarter rolling average Non-GAAP Adjusted Cash from Operations of $57.0 million.

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.
