FRAMINGHAM, Mass.--(BUSINESS WIRE)-- Ameresco, Inc. (NYSE:AMRC), a leading energy solutions provider dedicated to helping customers navigate the energy transition, today announced financial results for the fiscal quarter ended March 31, 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, “The first quarter represented an excellent start to the year with both our Projects and Energy Asset businesses delivering strong double-digit growth. We also increased future revenue visibility through robust contract conversion and asset deployments. During the quarter, we added over $367 million to awarded backlog while converting $334 million of awards into contracts. At quarter end our contracted backlog stood at $2.6 billion, almost 80% ahead of the previous year, driving our total project backlog to $4.9 billion up 22% compared to last year. Revenue visibility across our businesses now stands at almost $10 billion, adding to our long-term resilience.

“The Ameresco team continues to effectively and efficiently operate during these dynamic times. We are pleased to report that we have not encountered any additional cancellations or delays in our Federal contracts and those that we highlighted the previous quarter as being delayed or cancelled have now been “unpaused” or modified and are progressing. Importantly, we are now seeing a significant number of recently issued Federal RFPs, focused on our core competencies of resiliency and increasing power supply.

“Like every company in our industry we have also been dealing with rapidly changing tariff dynamics. While there will be some impact on costs, timing of deliveries and potentially lengthening implementation schedules, we believe that we have limited near-term exposure. We note that much of the equipment for ongoing Projects and Energy Assets has already been purchased and is in the country or already on our sites, shielding us from tariff and price increases. Beyond 2025, we will try to mitigate the effect of price increases during contract negotiations and repricing where possible. The Ameresco team has significant experience operating in such dynamic environments having successfully navigated Covid era inflation along with tariff impacts during previous administrations.

”Our increasing clarity and mitigation effort around Federal and tariff related dynamics, as well as the excellent visibility provided by our contracted project backlog and recurring revenue streams give us excellent visibility to delivering on our guidance for the year.”

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

(in millions)	Q1 2025			Q1 2024
	Revenue	Net Income (Loss) (1)	Adj. EBITDA	Revenue	Net (Loss) Income (1)	Adj. EBITDA
Projects	$251.5	$0.4	$8.7	$204.3	($6.0)	$3.2
Energy Assets	$56.7	($5.9)	$30.1	$43.2	$(0.5)	$21.2

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

Total revenue increased 18% to $352.8 million, with strong growth in Projects and Energy Assets revenue partially offset by a decline in Other revenue due to the divestiture of AEG at the end of 2024. Projects revenue grew 23% to $251.5 million, driven by our continued focus on project execution and the conversion of our awarded backlog to contracts. The Company continues to benefit from the increased number of operating Energy Assets placed in service, fueling a 31% increase in energy asset revenue to $56.7 million. The year-end sale of AEG led to the decline in Other revenue to $19.8 million. Gross margin of 14.7% was in line with expectations, slightly impacted by a heavier mix of lower margin EPC revenue related to our European JV. Net loss attributable to common shareholders was $5.5 million. Adjusted EBITDA of $40.6 million, increased 32%.

Summary and Outlook

Given our strong start to the year and excellent visibility we are reiterating our 2025 revenue and adjusted EBITDA guidance of $1.9 billion and $235 million at the midpoints of our ranges, respectively. Our team’s outstanding execution drove faster implementation during the first quarter of approximately $30 million of project revenue. To assist with shaping for the remainder of the year, we are maintaining our expectation for the cadence of revenue in the second half of 2025 to represent approximately 60% of our total revenue. Accounting for our strong Q1 results, we anticipate Q2 revenue will be in the range of approximately $400 - $425 million.

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

Non-GAAP Financial Guidance

Adjusted earnings before interest, taxes, depreciation and amortization (adjusted EBITDA):
Year Ended December 31, 2025
	Low	High
Operating income (1)	$113 million	$132 million
Depreciation and amortization	$103 million	$105 million
Stock-based compensation	$14 million	$16 million
Restructuring and other charges	$(5) million	$(8) million
Adjusted EBITDA	$225 million	$245 million
(1) Although net income is the most directly comparable GAAP measure, this table reconciles adjusted EBITDA to operating income because we are not able to calculate forward-looking net income without unreasonable efforts due to significant uncertainties with respect to the impact of accounting for our redeemable non-controlling interests and taxes.

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 Federal ESPC projects. Cash received in payment of Federal ESPC projects is treated as a financing cash flow under GAAP due to the unusual financing structure for these projects. These cash flows, however, correspond to the revenue generated by these projects. Thus, we believe that adjusting operating cash flow to include the cash generated 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 revenue generated by operations.
