Ameresco, Inc. (NYSE:AMRC), a leading energy solutions provider dedicated to helping customers navigate the energy transition, today announced financial results for the second quarter ended June 30, 2025. 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, “This was another strong quarter for Ameresco as the team continued its excellent execution across our broad operating footprint. Revenue growth of 8% exceeded our expectations, particularly considering the strong first quarter results during which we executed on projects worth approximately $30 million faster than anticipated. Second quarter revenue performance reflected strength across our business lines and was driven by continued growth in Europe and our Energy Asset business. Adjusted EBITDA increased 24%, demonstrating the significant operating leverage we believe is inherent in our Company’s unique business model, while Non-GAAP EPS was $0.17 higher from a year ago. In the second quarter, we also continued to further strengthen our foundation for future profitable growth with successful business development activities. The Company added over $550.0 million of new project awards during the quarter. Total Project Backlog stands at a record of $5.1 billion, with Energy Infrastructure and resiliency projects accounting for almost half.

“Rapidly increasing demand for electricity, rising utility rates and growing grid instability continue to drive tremendous interest and demand for our broad portfolio of Energy Infrastructure solutions. Our diverse portfolio of solutions includes natural gas-powered engines, co-gen equipment, hydroelectric power, other power generation technologies, as well as renewables, BESS and microgrid offerings. And to ensure we are active participants in the evolving Small Modular Reactor, or SMR market, we recently added a seasoned executive to lead the development of our Nuclear Partner Program. Our significant growth in Europe furthered our ongoing geographic diversification. To support this growth, we hired a key executive in Continental Europe. We believe this diversification and our continued investments in executive talent and leading-edge technologies allow us to thrive,” Mr. Sakellaris concluded.

Second Quarter Financial Results

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

Total revenue of $472.3 million increased 8%. Continued growth in Europe combined with our focus on project execution and the conversion of our backlog drove solid growth of 8% in our Projects revenue to $358.1 million. Energy Asset revenue grew 18% to $62.9 million, continuing to benefit from the cumulative impact of long-term contracts associated with our growing portfolio of operating Energy Assets. O&M revenue increased 7%, and Other revenue of $23.3 million was lower due to the sale of AEG at the end of 2024. Gross margin of 15.5% was in line with expectations. Net income attributable to common shareholders was $12.9 million with EPS and Non-GAAP EPS of $0.24 and $0.27, respectively. Q2 net income and EPS were positively impacted by $4.3 million in non-cash, mark-to-market gains on certain unhedged derivatives, and $3.0 million of fx translation gains. Adjusted EBITDA increased 24% to $56.1 million.

Project and Asset Highlights

• Ameresco brought 7 MWe of Energy Assets into operation

Balance Sheet and Cash Flow Metrics

The Company ended the quarter with $81.6 million in unrestricted cash with total corporate debt including our subordinated debt, term loans and drawn amounts on our revolving line of credit increasing to $294.1 million. Corporate debt increased in order to support our working capital needs given the continued growth of our business. During the quarter the Company successfully executed approximately $175.0 million in project financing commitments and the sale of over $70.0 million in RNG-related tax credits. Our Energy Asset Debt was $1.5 billion with an Energy Debt Advance rate of 74% on the Energy Asset Book Value. Our Adjusted Cash from Operations during the quarter was $49.6 million. Our 8-quarter rolling average Adjusted Cash from Operations was $46.9 million.

Outlook

“We are pleased to note that our business with the Federal Government is returning to a more normalized cadence, and while we continue to evaluate the industry changes brought about by the OBBB Act, we do not believe that these changes will have a material impact on Ameresco in the short term. With our strong first half results together with our visibility into the remainder of the year, we are pleased to reiterate our 2025 revenue and adjusted EBITDA guidance of $1.9 billion and $235 million at the midpoints of our ranges, respectively.”

Our 2025 guidance does not include the potential impact of a change in accounting principle related to sale-leaseback arrangements that continues to be assessed.

Non-GAAP Financial Measures (Unaudited, in thousands)

Other Financial Measures (Unaudited, in thousands)

Non-GAAP Financial Guidance

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.

Adjusted Cash from Operations

We define 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 a 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 adjusted cash from operations as a measure of liquidity because it captures all sources of cash associated with our operations.
