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 December 31, 2024. 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 fourth quarter represented a strong and resilient finish to an excellent year for Ameresco. Our team continued to deliver solid results in a dynamic business environment while positioning the Company for future growth and adding to our multi-year visibility. Our record revenue performance was driven by growth across our business lines, reflecting robust demand for cost effective projects that provide energy savings and resilience. This was also a record quarter in project contract conversions with over $1 billion, bringing our contracted project backlog to over $2.5 billion at year-end, approximately twice 2023 levels. We also placed a record 241 MWe of energy assets into service during the year. These accomplishments have added considerably to our total multiyear revenue visibility which now stands at almost $10 billion. During the quarter, we also successfully divested our AEG business unit allowing us to remain focused on our core businesses and the exciting growth opportunities within our target markets."

Fourth Quarter Financial Results

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

Total revenue increased 20.7% to $532.7 million, with growth across all four of our business lines. Projects revenue grew 20.7% to $418.3 million, driven by our focus on project execution and the conversion of our awarded backlog to contracts. Energy Assets revenue increased 31.2% to $57.6 million, on the strength of record growth in assets placed in service. O&M revenue increased 8.6% to $26.5 million reflecting a solid attachment rate to our growing projects business. Other revenue increased 13.7% to $30.2 million. Gross margin of 12.5% for the quarter was significantly lower than expected. Unanticipated cost overruns on two of our large-scale legacy projects, negatively impacted gross profit by approximately $20 million, or 400 basis points. Operating income of $44.6 million, included a gain recognized on the sale of our AEG business unit of approximately $38.0 million, was partially offset by non-cash impairment charges of approximately $12.0 million taken on certain energy assets and higher depreciation expenses of $8.0 million. Interest and other expenses, net was $23.4 million, representing an increase of 45.7%. We continued to take advantage of clean energy tax incentives, resulting in an effective tax rate benefit of (58.9)% compared to a benefit of (67.0)% in 2023. Net income attributable to common shareholders was $37.1 million, increasing by 14.6%. Adjusted EBITDA of $87.2 million, increased 58.7%.

Balance Sheet and Cash Flow Metrics

The Company ended 2024 with $108.5 million in cash. During the fourth quarter the Company executed the planned, strategic divestiture of our energy technology and advisory services business, AEG, which resulted in significant cash proceeds and a higher than expected gain of approximately $38.0 million. The Company used the net cash proceeds from the sale to pay down its corporate term loan, resulting in an improvement in the corporate debt leverage ratio as of December 31, 2024. Our total corporate debt including our subordinated debt, term loans and drawn amounts on our revolving line of credit declined to $243.1 million from $272.5 million. Subsequent to the year-end, we extended and increased this facility, providing further financial flexibility and increased capacity to help fund our growth. During the fourth quarter we successfully executed approximately $237.0 million in project financing commitments to help fund our Energy Asset business. Our Energy Asset Debt was $1.4 billion with an Energy Debt Advance rate of 73% on the Energy Asset Book Value. Our Adjusted Cash from Operations during the quarter was $53.8 million. Our 8-quarter rolling average Adjusted Cash from Operations was $45.8 million.

Project and Asset Highlights

• Ameresco brought 31 MWe of Energy Assets into operation, including the 15.6 MWe Roxana RNG plant.
• Ameresco's Assets in Development increased 48 MWe during the quarter to 637 MWe with the addition of a number of large battery and PV assets.
• The Southern California Edison projects continue to progress and we expect them to be finalized this year.

Summary and Outlook

"Entering 2025, Ameresco is well-positioned for continued long term profitable growth even in an evolving industry and political landscape. While we expect continued growth in our recurring energy assets and O&M businesses, our projects business, and specifically our federal projects, will be impacted as the new administration determines which projects align with its funding priorities. We expect there to be continued long-term demand for our budget-neutral, cost-saving solutions as energy demand and prices continue to increase. We also expect the growing need for resilient, reliable power and infrastructure upgrades to drive the continued growth of our energy solutions as these drivers align with the new administration's priorities. Additionally, we foresee growing contributions from our European business, with renewable projects driven by decarbonization and net-zero commitments. These critical market drivers and our proven tailored solutions will continue to bolster our status as a leading global market player."

Given the current unpredictable political and regulatory environment, we have evaluated our federal government exposure in our 2025 guidance. We are guiding revenue of $1.9 billion and adjusted EBITDA $235 million at the midpoints of our ranges. We have reviewed risks related to project cancellations, pauses and re-scopes and factored that into our guidance. However, if these factors last longer than anticipated, our earnings could be impacted.

We anticipate placing approximately 100-120 MWe of energy assets in service, including 1-2 RNG plants. Our expected capex is $350 million to $400 million, the majority of which we expect to fund with additional energy asset debt, tax equity or tax credit sales.

We anticipate that first quarter revenue and Adjusted EBITDA will be similar to Q1 last year. Because the first quarter is our seasonally lowest revenue quarter, and due to the generally linear nature of depreciation and interest expenses, we expect to have negative EPS. With respect to the cadence of revenue, we expect revenues in the second half of the year to represent approximately 60% of our total revenue for 2025. This is consistent with our performance from the past couple of years.

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. If implemented, this change could result in lower annual interest and other expenses with an estimated impact of approximately $20 million in 2025.

Non-GAAP Financial Measures (Unaudited, in thousands)

Other Financial Measures (In thousands) (Unaudited)

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 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.
