1. BASIS OF PRESENTATION
The accompanying condensed consolidated financial statements of Ameresco, Inc. (including its subsidiaries, the “Company,” “Ameresco,” “we,” “our,” or “us”) are unaudited, according to certain rules and regulations of the Securities and Exchange Commission, and include, in our opinion, normal recurring adjustments necessary for a fair presentation in conformity with accounting principles generally accepted in the United States (“GAAP”) of the results for the periods indicated.
The results of operations for the three and six months ended June 30, 2025 are not necessarily indicative of results which may be expected for the full year. The December 31, 2024 consolidated balance sheet data was derived from audited financial statements, but certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with GAAP have been condensed or omitted. The interim condensed consolidated financial statements and accompanying notes should be read in conjunction with the audited consolidated financial statements and accompanying notes for the year ended December 31, 2024, included in our annual report on Form 10-K (“2024 Form 10-K”) filed with the Securities and Exchange Commission on February 28, 2025.
Reclassification and Rounding
Certain prior period amounts were reclassified to conform to the presentation in the current period. We round amounts in the condensed consolidated financial statements to thousands and calculate all percentages and per-share data from the underlying whole-dollar amounts. Thus, certain amounts may not foot, crossfoot, or recalculate based on reported numbers due to rounding.
Significant Risks and Uncertainties
Global factors have continued to result in global supply chain disruptions.
We have considered the impact of general global economic conditions on the assumptions and estimates used, which may change in response to this evolving situation. Results of future operations and liquidity could be adversely impacted by a number of factors including supply chain disruptions, varying levels of inflation, payments of outstanding receivable amounts beyond normal payment terms, workforce disruptions, and uncertain demand. As of the date of issuance of these condensed consolidated financial statements, we cannot reasonably estimate the extent to which macroeconomic conditions may impact our financial condition, liquidity, or results of operations in the foreseeable future. The ultimate impact of the general global economic conditions on our business is highly uncertain and will depend on future developments, and such impacts could exist for an extended period of time.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Our accounting policies are set forth in Note 2 to the consolidated financial statements contained in our 2024 Form 10-K. We have included certain updates to those policies below.

Recent Accounting Pronouncements

Business Combinations— Joint Venture Formations
In August 2023, the FASB issued ASU 2023-05, Business Combinations— Joint Venture Formations (Subtopic 805-60) Recognition and Initial Measurement, which addresses the accounting for contributions made to a joint venture, upon formation, in a joint venture’s separate financial statements. ASU 2023-05 is effective prospectively for all joint venture formations with a formation date on or after January 1, 2025. We adopted this new accounting standard effective January 1, 2025 and the adoption did not have a material impact on our condensed consolidated financial statements.
Income Taxes (Topic 740) - Improvements to Income Tax Disclosures
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, to enhance the income tax disclosures, including disaggregation of information in the rate reconciliation table and disaggregated information related to income taxes paid. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. We are currently evaluating the impact that adopting this new accounting standard would have on our annual condensed consolidated financial statements.
Codification Improvements—Amendments to Remove References to the Concepts Statements
In March 2024, the FASB issued ASU 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements, to remove references to various FASB Concepts Statements based on suggestions received from stakeholders on the Accounting Standards Codification and other incremental improvements to GAAP. ASU 2024-02 is effective for fiscal years beginning after December 15, 2024.

Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, to improve the disclosures by requiring more detailed information about the types of expenses (including purchases of inventory, employee compensation, depreciation, amortization, and depletion) in commonly presented expense captions (such as cost of sales, SG&A, and research and development). ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. In January 2025, the FASB issued ASU 2025-01, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40), to modify the effective date previously stated in ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. We are currently evaluating the impact that adopting ASU 2024-03 would have on our condensed consolidated financial statements and will adhere to the clarified effective date in ASU 2025-01 if implementation is necessary.

(1) Performance obligations that are expected to be completed beyond the next twelve months and are included in other liabilities in the condensed consolidated balance sheets.
The decrease in contract assets for the six months ended June 30, 2025 was primarily due to billings of $598,064, offset by revenue recognized of $527,653, as well as reclassifications, primarily from contract liabilities as a result of the timing of customer payments. The increase in contract liabilities was primarily driven by the receipt of advance payments from customers, and related billings, as well as reclassifications from contract assets as a result of timing of customer payments. The advance payments and reclassifications exceeded the recognition of revenue as performance obligations were satisfied. For the six months ended June 30, 2025, we recognized revenue of $239,308 and billed $217,506 to customers that had balances which were included in contract liabilities at December 31, 2024.
The increase in contract assets for the six months ended June 30, 2024 was primarily due to revenue recognized of $490,125 offset by billings of $494,441. Contract assets also increased due to reclassifications, primarily from contract liabilities as a result of timing of customer payments. The increase in contract liabilities was primarily driven by the receipt of advance payments from customers, and related billings, as well as reclassifications from contract assets as a result of timing of customer payments.

Performance Obligations
Our remaining performance obligations (“backlog”) represent the unrecognized revenue value of our contract commitments. At June 30, 2025, we had contracted backlog of $3,761,721 of which approximately 35% is anticipated to be recognized as revenue in the next twelve months. The remaining performance obligations primarily relate to the energy efficiency and renewable energy construction projects, including long-term operations and maintenance (“O&M”) services related to these projects. The long-term services have varying initial contract terms, up to 27 years.
Deferred Project Costs
Deferred project costs include costs incurred on active projects which will be reclassified either to contract assets or energy assets, as applicable, once a change order or other project resolution is finalized.
Project Development Costs
Project development costs of $4,045 and $3,164 were recognized in our condensed consolidated statements of income (loss) on projects that converted to customer contracts during the three months ended June 30, 2025 and 2024, respectively. Project development costs of $8,481 and $6,284 were recognized in the condensed consolidated statements of income (loss) on projects that converted to customer contracts during the six months ended June 30, 2025 and 2024, respectively.
No impairment charges in connection with our project development costs were recorded during the three or six months ended June 30, 2025 and 2024.
4. BUSINESS ACQUISITIONS AND RELATED TRANSACTIONS
We account for acquisitions using the acquisition method in accordance with ASC 805, Business Combinations. The purchase price for each acquisition is allocated to the assets based on their estimated fair values at the date of acquisition. The excess purchase price over the estimated fair value of the net assets acquired, which is calculated using level 3 inputs per the fair value hierarchy as defined in Note 11, is recorded as goodwill. Intangible assets, if identified, are also recorded. See Note 5 for additional information.
ASA Controls, Inc.

On January 24, 2025, we entered into an asset purchase agreement to acquire ASA Controls, Inc., an Ohio-based energy services company that specializes as a regional controls contractor and systems integrator within the smart buildings sector. As of June 30, 2025, we paid $3,972 in cash. There is no contingent consideration related to this acquisition. We recorded goodwill and intangible assets in connection with this acquisition. See Note 5. The historical and pro-forma effects of this acquisition on our operations, contribution to revenue, and net income for the three and six months ended June 30, 2025 were not material.

We have a future lease commitment for a project lease with the United States Navy (“Navy”) which has not yet met the criteria for recording a right-of-use (“ROU”) asset or ROU liability. The estimated net present value of this commitment totals $40,335 as of June 30, 2025. We will provide IKCPs over a thirty-six-year period, which the Navy will credit as consideration towards our lease obligation upon the Navy’s final acceptance of the IKCPs. Once the lease commences, the ROU asset and liability will be recorded, which we estimate to be in late 2025 or early 2026.
Non-monetary Lease Transactions
We have six lease liabilities consisting of obligations that will be settled with non-monetary consideration. The lease liabilities relating to non-monetary consideration are based on the fair market value of the project services or back up power expected to be provided, which approximate the cash payments.
Financing Leases
Net gains from amortization expense recognized in cost of revenues relating to deferred gains and losses in connection with our sale-leaseback agreements were $57 and $114 for the three and six months ended June 30, 2025 and 2024, respectively.

(3) These facilities are accounted for as failed sale-leasebacks and are classified as long-term financing facilities. See Note 7 for additional disclosures.
(4) Financing lease liabilities are sale-leaseback arrangements under previous guidance. See Note 7 for additional disclosures.
Senior Secured Corporate Credit Facility
On January 23, 2025, we refinanced our term loan and revolving credit facility by entering into a sixth amended and restated senior secured credit agreement (“Restated Credit Agreement”) with the group of lenders thereto. The interest rate for borrowings is based on, at our option, either the Base Rate plus a margin of 0.75% to 1.75%, depending on our core leverage ratio; or the Term SOFR plus a margin of 1.75% to 2.75%, depending on our core leverage ratio. A commitment fee of between 0.25% and 0.375%, depending on our core leverage ratio, is payable quarterly on the undrawn portion of the revolver. As of June 30, 2025, the interest rates were 6.85% and 7.48% per annum for the term loan and revolving credit facility, respectively. At closing we paid $2,345 in lenders fees and debt issuance costs. Proceeds from this agreement in the amount of $180,000 and $13,000 were used to pay the balance of our revolving credit facility and the outstanding portion of the senior secured term loan, respectively, at closing.
The Restated Credit Agreement replaced and extended Ameresco's existing credit agreement dated March 4, 2022, and subsequently amended (the “Original Credit Agreement”). The Restated Credit Agreement refinanced the credit facilities under the Original Credit Agreement and replaced it with the following facilities:
•a $225,000 revolving credit facility, maturing on December 28, 2028, and
•a $100,000 term loan, maturing on December 28, 2028
The revolver may be increased by up to an additional $100,000 at Ameresco's option if lenders are willing to provide such increased commitments, subject to certain conditions.
Additional terms of the Restated Credit Agreement are as follows:
•the term loan requires quarterly principal payments of $1,250 starting March 31, 2025, with the balance due at maturity
•the revolving credit facility requires payment at maturity
•a debt service coverage ratio (as defined in the agreement) of at least 1.5 to 1.0
•a total funded debt to EBITDA of less than 3.5 to 1.0

April 2025 Senior Secured Notes, 6.72%, due September 30, 2045 and Term Shelf Note
On April 30, 2025 we entered into a note purchase agreement and private shelf agreement which includes committed proceeds under series A notes of $78,000 to finance a battery energy storage asset in development, with a maturity date of September 30, 2045, and a fixed interest rate of 6.72% per annum. Gross proceeds from the initial issuance on April 30, 2025 were $67,708 with the remaining $10,291 issued on June 27, 2025. At closing, we incurred $3,126 in lenders fees and debt issuance costs. In connection with this note, we recorded one derivative instrument for make-whole provisions with an initial value of $3,040 which was recorded as debt discount. The agreement also includes a 20-year term $300,000 private shelf facility, as well as the ability to issue series B notes with a maturity date of September 30, 2045 on or before December 31, 2025. As part of this transaction, we signed a tax credit transfer agreement for the investment tax credits associated with the BESS asset. Upon the asset achieving commercial operations, we will receive proceeds from the ITC transfer and a $30,000 prepayment on the note purchase agreement will be required.
May 2025, Term Loan, 6.62%, due December 31, 2037
On May 27, 2025, we entered into a term loan agreement which provided a term loan in a principal amount of $12,221 with a maturity date of December 31, 2037. The term loan bears a fixed interest rate of 6.62%. Interest is payable quarterly. At closing, we incurred $402 in lenders fees and debt issuance costs. Proceeds from this term loan in the amount of $8,273 were used to pay a portion of the October 2012 term loan. In connection with this term loan we recorded one derivative instrument for a make-whole provision with an initial value of $347 which was recorded as debt discount.
See Note 12 for additional information about the derivative instruments.
October 2012, Term Loan, 6.87%, due June 30, 2025
On May 27, 2025, we paid off the term loan with a balance of $31,086, partially with $8,273 from the May 2025 term loan proceeds and the remainder with working capital cash. With this debt termination, we also terminated four interest rate swap contracts that were not previously designated as hedged instruments.
October 2022, Financing Facility, 6.70%, due August 31, 2039
On May 27, 2025 we entered into an omnibus amendment as part of a tax credit transfer agreement for investment tax credits. The amendment required a $7,000 principal payment, which was made during the three months ended June 30, 2025. During the six months ended June 30, 2025, we made no additional draw downs and at June 30, 2025, $345,173 was outstanding under this facility, net of unamortized debt discount and issuance costs.
August 2023, Construction Credit Facility, 8.32%, due December 15, 2027
During the six months ended June 30, 2025, we drew an additional $138,655, paid down $60,213, and at June 30, 2025, $390,574 was outstanding under this facility, net of unamortized debt discount and issuance costs. The Powin bankruptcy triggered a default under this facility, requiring us to move the project associated with the battery payment deposits we made to Powin out of this facility. We subsequently received a waiver effective July 31, 2025 of this default as well as of a default of certain lien provisions under the facility.
June 2020, Construction Credit Facility, 5.93%, due March 31, 2026
During the six months ended June 30, 2025, we entered into an amendment to extend this revolver, and the current maturity date is March 31, 2026.
During the three months ended June 30, 2025, there were no additional draw downs and as of June 30, 2025, $19,205 was outstanding and $80,795 was available for borrowing.

August 2018 Master Sale-leaseback
We enter into amendments to our August 2018 master lease and participation agreement from time to time, which may extend the maturity date, increase the availability, or modify other covenants. During the six months ended June 30, 2025, we entered into an amended and restated participation agreement which extended the participation date from June 30, 2025 to March 31, 2026. During the three months ended June 30, 2025, we were default of certain lien provisions of this agreement. On June 30, 2025, we received a waiver of this default.
We sold and leased back five energy assets for $18,946 in cash proceeds under this facility during the six months ended June 30, 2025.
December 2020 Master Sale-leaseback
We enter into amendments to our December 2020 master lease and participation agreement from time to time, which may extend the maturity date, increase the availability, or modify other covenants. As of March 31, 2025, we were in default under this agreement as we had failed to satisfy the historical coverage ratio under this agreement. On May 5, 2025, we received a waiver of this default.
9. INCOME TAXES
We recorded an income tax benefit of $2,900 and $0 for the three months ended June 30, 2025 and 2024, respectively. We recorded an income tax benefit of $1,712 and $0 for the six months ended June 30, 2025 and 2024, respectively.
The effective tax rate benefit was 23.0% for the three months ended June 30, 2025, compared to the effective tax rate of 0.0% for the three months ended June 30, 2024. The effective tax rate benefit was 20.9% for the six months ended June 30, 2025, compared to effective tax rate of 0.0% for the six months ended June 30, 2024. The principal reasons for the lower effective rate for the three months and six months ended June 30, 2025 is due to the effects of higher investment tax credits from solar, and storage plants placed into service or are forecasted to be placed into service during 2025 and effects of foreign earnings, offset by a lower Section 179D Energy Efficient Building deduction.
10. COMMITMENTS AND CONTINGENCIES
From time to time, we issue letters of credit and performance bonds with our third-party lenders, to provide collateral.
Legal Proceedings
We are involved in a variety of other claims and other legal proceedings generally incidental to our normal business activities. When we conclude that it is probable that a liability has been incurred and the amount of the liability can be reasonably estimated, it is accrued through a charge to earnings and, if material, disclosed below. When only a range of amounts is reasonably estimable and no amount within the range is more likely than another, the low end of the range is recorded. While the ultimate amount of liability incurred in any of these matters is dependent on future developments, in our opinion, the recorded liability is adequate to cover the future payment of such liability and claims. However, the final outcome of any of these claims and legal proceedings cannot be predicted with certainty, and unfavorable or unexpected outcomes could result in additional accruals that could be significant to results of operations in a particular year or quarter. Any adjustments to the recorded liability will be reflected in earnings in the periods in which such adjustments become known. For any other claims where a loss may be reasonably possible, but not probable, or is probable but not reasonably estimable, no accrual is established, but the matter, if potentially material, is disclosed below. We routinely review relevant information with respect to our matters and update our accruals, disclosures and estimates of reasonably possible loss based on such reviews. While the outcome of any of these matters cannot be accurately predicted, we do not believe the ultimate resolution of any of these existing matters would have a material adverse effect on our financial condition or results of operations.
In October 2021, we entered into a contract with SCE to design and build three grid scale battery energy storage system (“BESS”) at three sites near existing substation parcels throughout SCE’s service territory in California with an aggregate capacity of 537.5 megawatt (“MW”) (“the SCE Agreement”). As previously disclosed, due to supply chain delays, weather, and other events, we were unable to complete the projects by August 1, 2022 (the “Guaranteed Completion Date”) and made related force majeure claims. In late 2022, SCE also instructed us to adjust the completion of the sites into 2023. Under the SCE Agreement, a failure to reach the Guaranteed Completion Date could, under certain circumstances, result in liquidated damages up to a maximum amount of $89 million being applied. On August 30, 2024, we reached an agreement with SCE on the substantial completion of two out of

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(In thousands) (Unaudited) (Continued)
three battery energy storage system projects. We received approximately $110 million on September 5, 2024 as milestone payments, reflecting a set-off of liquidated damages for these two projects. The agreement confirmed that the final resolution related to our obligation to pay the liquidated damages withheld and the applicability and scope of any force majeure relief as well as any cost recovery we may be entitled to remain subject to dispute. We are continuing discussions with SCE on these matters, and our view continues to be that liquidated damages should not be applied. It is at least reasonably possible we may incur an obligation to pay liquidated damages up to the maximum amount.
Commitments as a Result of Acquisitions
In December 2021, we completed our acquisition of Plug Smart which provided for an earn-out based on future EBITDA targets beginning with EBITDA performance for the month of December 2021 and each fiscal year thereafter, over a five-year period through December 31, 2026. The maximum cumulative earn-out is $5,000 and we evaluated financial forecasts of the acquired business and concluded that the fair value of this earn-out was approximately $1,614 at December 31, 2024. As of June 30, 2025, the EBITDA targets and maximum cumulative earn-out were achieved, and the fair value of the remaining contingent consideration increased by $71 to $1,685. A payment of $1,685 was made as of June 30, 2025. See Note 11 for additional information.
Powin LLC
On June 10, 2025, Powin LLC (“Powin”), one of our BESS suppliers, voluntarily filed for protection under Chapter 11 of the U.S. Bankruptcy Code in the United States Bankruptcy Court. As of the date of this report, Ameresco paid Powin $26,683 in deposits for transactions that never materialized and are recorded within other assets in the accompanying condensed consolidated balance sheets. We are actively monitoring the proceedings, and the range of loss is between $0 and $26,683. Since it is early in the bankruptcy proceedings a loss cannot be reasonably estimated, therefore, no loss has been accrued at this time.
11. FAIR VALUE MEASUREMENT
We recognize our financial assets and liabilities at fair value on a recurring basis. Fair value is defined as the price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Three levels of inputs that may be used to measure fair value are as follows:
Level 1: Inputs are based on unadjusted quoted prices for identical instruments traded in active markets. 
Level 2: Inputs are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant assumptions are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities. 
Level 3: Inputs are generally unobservable and typically reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. The fair values are therefore determined using model-based techniques that include option pricing models, discounted cash flow models, and similar techniques. 
The following table presents the input level used to determine the fair values of our financial instruments measured at fair value on a recurring basis:

Long-term debt (Level 2) $1,801,014 $1,809,748 $1,618,208 $1,620,359 
The fair value of our long-term debt was estimated using discounted cash flows analysis, based on our current incremental borrowing rates for similar types of borrowing arrangements which are considered to be level two inputs. There have been no transfers in or out of level two or three financial instruments for the six months ended June 30, 2025 and the year ended December 31, 2024.
We are also required to periodically measure certain other assets at fair value on a nonrecurring basis, including long-lived assets, goodwill and other intangible assets. We calculated the fair value used in our annual goodwill impairment analysis utilizing a discounted cash flow analysis and determined that the inputs used were level 3 inputs. There were no assets recorded at fair value on a non-recurring basis as of June 30, 2025 or December 31, 2024.

We also added 2 embedded derivatives for make-whole provisions with an initial fair value totaling $3,387. See Note 8 for additional information about the financings.

See Note 14 for additional information on the call and put options related to our investment funds.
Non-controlling Interests
Non-controlling interests represents the equity owned by the other joint venture members of consolidated joint ventures. On February 9, 2024, we entered into an agreement to sell a 40% interest in an energy asset, thus forming a joint venture, and we received $28,864 in cash. We also received additional contributions totaling $6,543 during the year ended December 31, 2024 and $3,799 during the six months ended June 30, 2025.
Equity and Cost Method Investments
Unconsolidated joint ventures are accounted for under the equity method. For these unconsolidated joint ventures, our investment balances are included in other assets on the condensed consolidated balance sheets, and our pro rata share of net income or loss is included in earnings from unconsolidated entities on the condensed consolidated statements of income (loss).

14. REDEEMABLE NON-CONTROLLING INTERESTS
Our subsidiaries with membership interests in the investment funds we formed have the right to elect to require the non-controlling interest holder to sell all of its membership units to our subsidiaries, a call option. Our investment funds also include rights for the non-controlling interest holder to elect to require our subsidiaries to purchase all of the non-controlling membership interests in the fund, a put option.
We had one investment fund remaining as of June 30, 2025 and December 31, 2024.
We initially record our redeemable non-controlling interests at fair value on the date of acquisition and subsequently adjust to redemption value. At both June 30, 2025 and December 31, 2024, the remaining redeemable non-controlling interest was reported at its carrying values, as the carrying value at each reporting period was greater than the estimated redemption value.

Our stock-based compensation expense is included in selling, general and administrative expenses in the condensed consolidated statements of income (loss). As of June 30, 2025, there was $27,735 of unrecognized compensation expense related to non-vested stock option awards that is expected to be recognized over a weighted-average period of 2.8 years. This includes $4,236 of unrecognized compensation expense related to PSOs based on our current assessment of probability. There is an additional $7,646 of unrecognized compensation expense if the PSOs were to achieve 100% probability.
Stock Option and Restricted Stock Units (“RSUs”) Grants
During the six months ended June 30, 2025, we granted 1,388 common stock options to certain employees under our 2020 Stock Incentive Plan (“2020 Plan”), which have a contractual life of ten years and vest over a three or five-year period. We also granted awards of 137 RSUs to certain employees and directors under our 2020 Plan. RSUs for directors cliff vest after one year and RSUs for employees vest 25% every six months for two years. We did not grant awards to individuals who were not either an employee or director of ours during the six months ended June 30, 2025 and 2024.
17. BUSINESS SEGMENT INFORMATION
Our reportable segments are North America Regions, U.S. Federal, Europe, Renewable Fuels, and All Other.
Our North America Regions, U.S. Federal, and Europe segments offer energy efficiency products and services which include the design, engineering, and installation of equipment and other measures to improve the efficiency and control the operation of a facility’s energy infrastructure, renewable energy solutions, and services which include the construction of small-scale plants that Ameresco owns or develops for customers that produce electricity, gas, heat, or cooling from renewable sources of energy and O&M services.
Our Renewable Fuels segment sells electricity, processed renewable gas fuel, heat or cooling, produced from renewable sources of energy, other than solar, and generated by small-scale plants that we own and O&M services for customer owned small-scale plants. Our North America Regions segment also includes certain small-scale solar grid-tie plants developed for customers.
The “All Other” category offers consulting services and the sale of solar PV energy products and systems which we refer to as integrated-PV.
These segments do not include results of other activities, such as corporate operating expenses not specifically allocated to the segments. Certain reportable segments are an aggregation of operating segments.
Our Chief Executive Officer and President is our chief operating decision maker (“CODM”). The CODM is responsible for making operating decisions, allocating resources, and assessing performance of the business segments. The CODM uses the segments’ income before income taxes as the profitability measure in making these decisions.

Overview
Ameresco is a leading energy solutions provider dedicated to helping customers navigate the energy transition. Our comprehensive portfolio includes implementing smart energy efficiency solutions, upgrading aging infrastructure, and developing, constructing, and operating distributed energy resources.
Drawing from decades of experience, Ameresco reduces energy use and delivers diversified generation solutions to Federal, state and local governments, utilities, educational and healthcare institutions, housing authorities, and commercial and industrial customers.
We provide solutions primarily throughout North America and Europe, and our revenues are derived principally from energy efficiency projects, which entail the design, engineering, and installation of equipment and other measures that incorporate a range of innovative technology and techniques to improve the efficiency and control the operation of a facility’s energy infrastructure; this can include designing and constructing a central plant or cogeneration system for a customer providing power, heat and/or cooling to a building, or other small-scale plant that produces electricity, gas, heat or cooling from renewable sources of energy. We also derive revenue from long-term O&M contracts, energy supply contracts for renewable energy operating assets that we own, integrated-PV, and consulting and enterprise energy management services.
In addition to organic growth, strategic acquisitions of complementary businesses and assets, and joint venture arrangements have been an important part of our growth enabling us to broaden our service offerings and expand our geographical reach.
Key Factors and Trends
Regulatory Environment and Federal Policies
Federal policies play an important role in our business and we benefit from regulatory measures and various clean energy tax incentives, including those implemented under the Inflation Reduction Act (the “IRA”). These credits were modified by the One Big Beautiful Bill Act (the “OBBB”), which was enacted on July 4, 2025.


30
Table of Contents

Among other provisions, the OBBB introduces new timing requirements for solar-only projects seeking eligibility for Investment Tax Credits (the “ITC”) under Section 48 of the Internal Revenue Code (the “Code”). To qualify, such projects must commence construction by July 4, 2026, and be placed in service by December 31, 2027. The OBBB also phases down ITCs for energy storage projects beginning in 2034, with a complete phase-out by 2036. Additionally, it increases the requirements for the domestic content bonus credit and introduces new compliance obligations under the Foreign Entity of Concern (“FEOC”) provisions for solar and energy storage projects beginning construction in 2026. On July 7, 2025, the President issued an Executive Order directing the Secretary of the Treasury to issue updated guidance within 45 days regarding the “beginning of construction” criteria applicable to clean energy projects and mandating implementation of the FEOC restrictions under the OBBB.
These legislative and regulatory developments may adversely impact our eligibility for certain tax credits, the attractiveness of our solar and energy storage system offerings, and overall demand for our products. If we are unable to meet the revised domestic content or FEOC requirements, our ability to qualify for these incentives could be impaired, which may adversely affect our revenue, gross margins, business operations and competitive position.
See “Our business depends in part on federal, state, provincial and local government support or the imposition of additional taxes, tariffs, duties, or other assessments on renewable energy or the equipment necessary to generate or deliver it, for energy efficiency and renewable energy, and a decline in such support could harm our business” and “Compliance with environmental laws could adversely affect our operating results” in Item 1A, Risk Factors in our 2024 Form 10-K.
Supply Chain Disruptions and Other Global Factors
We continue to monitor the impact of global economic conditions on our operations, financial results, and liquidity, such as the impact of tariffs, supply chain challenges, the wars in Ukraine and the Middle East, evolving relations between the U.S. and China, and other geopolitical tensions. Import duties, tariffs and other import restrictions, including the Uyghur Forced Labor Protection Act, restrict the global supply of, and raise prices for, supplies needed for our business. In addition, tariffs and trade restrictions that have been introduced and may be introduced as part of the 'America First' trade policy may further increase the cost of components needed for our offerings and may strain trade relations, create inflationary pressures and cause additional supply chain disruptions. The impact to our future operations and results of operations as a result of these global trends remains uncertain and the challenges we face, including increases in costs for logistics and supply chains, intermittent supplier delays, and shortages of certain components needed for our business, such as electrical equipment, steel and aluminum as well as BESS equipment or components required for our projects and clean energy solutions may continue or become more pronounced.
During the six months ended June 30, 2025, we continued to face supply chain disruptions and varying levels of inflation driven by macroeconomic conditions. This caused some delays in the timely delivery of material to customer sites and in the timely completion of certain projects and increased shipping, transportation, component and labor costs, negatively impacting our results of operations during the six months ended June 30, 2025. We expect these challenges will persist and they may intensify. We continue to monitor macroeconomic conditions to remain flexible and to optimize and evolve our business as appropriate to address the challenges presented from these conditions.
These tariffs, restrictions, and strained trade relations may affect our ability to source materials and products, potentially leading to increased costs, supply chain disruptions and operational challenges, and decreased demand for our offerings. We are closely monitoring the regulatory environment and actions of the current administration that could impact our business.
Climate Change and Effects of Seasonality
Global emphasis on climate change and reducing carbon emissions has created opportunities for our industry. Sustainability has been at the forefront of our business since its inception, and we are committed to staying at the leading edge of innovation taking place in the energy sector. We believe the next decade will be marked by dramatic changes in the power infrastructure with resources shifting to more distributed assets, storage, and microgrids to increase overall reliability and resiliency.
Climate change also brings risks, as the impacts have caused us to experience more frequent and severe weather interferences, and this trend is expected to continue. We are subject to seasonal fluctuations and construction cycles, particularly in climates that experience colder weather during the winter months, such as the northern United States and Canada, and climates that experience extreme weather events, such as wildfires, storms or flooding, hurricanes, or at educational institutions, where large projects are typically carried out during summer months when their facilities are unoccupied. In addition, government customers, many of which have fiscal years that do not coincide with ours, typically follow annual procurement cycles and appropriate funds on a fiscal-year basis even though contract performance may take more than one year. Further, government contracting cycles can be affected by the timing of, and delays in, the legislative process related to government programs and incentives that help drive demand for energy efficiency and renewable energy projects. As a result, our revenues and operating income in the third and fourth quarter are typically higher, and our revenues and operating income in the first quarter are typically lower, than in other
31
Table of Contents

quarters of the year, however, this may become harder to predict with the potential effects of climate change. As a result of such fluctuations, we may occasionally experience declines in revenues or earnings as compared to the immediately preceding quarter, and comparisons of our operating results on a period-to-period basis may not be meaningful.
Our annual and quarterly financial results are also subject to significant fluctuations as a result of other factors, many of which are outside our control. See “Our business is affected by seasonal trends and construction cycles, and these trends and cycles could have an adverse effect on our operating results” and “Extreme weather events and other natural disasters, particularly those exacerbated by climate change, could materially affect our ability to complete our projects and develop our assets” in Item 1A, Risk Factors in our 2024 Form 10-K.
The Southern California Edison (“SCE”) Agreement
In October 2021, we entered into a contract with SCE to design and build three grid scale BESS at three sites near existing substation parcels throughout SCE’s service territory in California with an aggregate capacity of 537.5 MW (the “SCE Agreement”). The engineering, procurement and construction price is approximately $892.0 million in the aggregate, including two years of O&M revenues, subject to customary potential adjustments for changes in the work. As previously disclosed, due to supply chain delays, weather and other events, we were unable to complete the projects by August 1, 2022 (the “Guaranteed Completion Date”). On August 30, 2024, we reached an agreement with SCE on the substantial completion of two out of three battery energy storage system projects. We received approximately $110 million on September 5, 2024 as milestone payments, reflecting both an offset of liquidated damages which are still in dispute and $3 million that SCE withheld for additional work SCE required. Upon final acceptance of these two projects, we will invoice SCE for the remaining final acceptance milestone payments for these projects. We have provided SCE notice for substantial completion of the third project and are in discussions with SCE to reach agreement on the achievement of this milestone. We continue to expect all three projects to be finalized this year.
The August 2024 agreement with SCE confirmed that the final resolution related to our obligation to pay the liquidated damages withheld and the applicability and scope of any force majeure relief as well as any cost recovery we may be entitled to remain subject to dispute. We are continuing discussions with SCE on these matters, and our view continues to be that liquidated damages should not be applied. If we fail to come to an agreement with SCE about the applicability and scope of force majeure relief and liquidated damages, we may be required to pay liquidated damages up to an aggregate maximum of $89 million and may not be able to recover costs associated with the force majeure events.
A majority of our revenues under this contract were recognized in 2022 based upon costs incurred in 2022 relative to total expected costs on this project.
Stock-based Compensation
During the six months ended June 30, 2025, we granted 1,388,000 common stock options and 136,770 restricted stock units (“RSUs”) to certain employees under our 2020 Plan. Our unrecognized stock-based compensation expense was $27.7 million at June 30, 2025, compared to $28.0 million at December 31, 2024, and is expected to be recognized over a weighted-average period of three years. See Note 16 “Stock-based Compensation” for additional information.
Backlog and Awarded Projects
Backlog is an important metric for us because we believe strong order backlogs indicate growing demand and a healthy business over the medium to long term, conversely, a declining backlog could imply lower demand.
32
Table of Contents

The following table presents our backlog:
As of June 30,
(In Thousands)20252024
Project Backlog
Fully-contracted backlog$2,415,369 $1,650,562 
Awarded, not yet signed customer contracts2,688,537 2,762,481

O&M Backlog
Fully-contracted backlog$1,346,352 $1,185,890 
12-month O&M backlog$101,272 $89,773 
Total project backlog represents energy efficiency projects that are active within our sales cycle. Our sales cycle begins with the initial contact with the customer and ends, when successful, with a signed contract, also referred to as fully-contracted backlog. Our sales cycle averages 18 to 42 months. Awarded backlog is created when a potential customer awards a project to Ameresco following a request for proposal. Once a project is awarded but not yet contracted, we typically conduct a detailed energy audit to determine the scope of the project as well as identify the savings that may be expected to be generated from upgrading the customer’s energy infrastructure. At this point, we also determine the subcontractors, what equipment will be used, and assist in arranging for third party financing, as applicable. It takes an average of 12 to 24 months to convert our awarded backlog to fully-contracted backlog. It may take longer, as it depends on the size and complexity of the project. Historically, approximately 90% of our awarded backlog projects have resulted in a signed contract. After the customer and Ameresco agree to the terms of the contract and the contract is executed, the project moves to fully-contracted backlog. The contracts reflected in our fully-contracted backlog typically have a construction period of 12 to 36 months and we typically expect to recognize revenue for such contracts over the same period.
Our O&M backlog represents expected future revenues under signed, multi-year customer contracts for the delivery of O&M services, primarily for energy efficiency and renewable energy construction projects completed by us for our customers.
We define our 12-month backlog as the estimated amount of revenue that we expect to recognize in the next twelve months from our fully-contracted backlog. See “We may not recognize all revenues from our backlog or receive all payments anticipated under awarded projects and customer contracts” and “In order to secure contracts for new projects, we typically face a long and variable selling cycle that requires significant resource commitments and requires a long lead time before we realize revenues” in Item 1A, Risk Factors in our 2024 Form 10-K.
Assets in Development
Assets in development, which represents the potential design/build project value of renewable energy plants that have been awarded or for which we have secured development rights, were estimated at $2.25 billion and $2.34 billion, net of amount attributable to a non-controlling interest at June 30, 2025 and 2024, respectively. This is another important metric because it helps us gauge our future capital expenditure needs and develop-and-sell opportunities as well as our capacity to generate electricity or deliver renewable gas fuel, which contributes to our recurring revenue stream.

Our results of operations for the three months ended June 30, 2025 are due to the following:
•Revenues: total revenues for the three months ended June 30, 2025 increased over 2024 primarily due to a $27.3 million, or 8%, increase in our project revenues attributed to the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects, and a $9.5 million, or 18% increase in energy asset revenue resulting from the continued growth of our operating portfolio.
•Cost of Revenues and Gross Profit: the increase in cost of revenues is primarily due to the increase in project revenues described above and higher depreciation expenses from the continued growth in our operating assets portfolio.
•Selling, General and Administrative Expenses (“SG&A”): SG&A expenses for the three months ended June 30, 2025 increased from 2024 primarily due to increases in payroll and related benefits and restructuring charges and professional fees, partially offset by lower miscellaneous other charges.
•Other Expenses, Net: Other expenses, net for the three months ended June 30, 2025 decreased over 2024 primarily due to increased gains from derivatives transactions of $2.7 million and gains from foreign currency transactions of $3.0 million compared to losses of $0.5 million last year, partially offset by higher interest expenses, net of $5.1 million related to an increase in the amount of energy asset financings and corporate debt outstanding and higher interest rates.
•Income Tax Benefit: the benefit for income taxes is based on various rates set by federal, state, provincial and local authorities and is affected by differences between financial accounting and tax reporting requirements. We expect the effective tax rate benefit will be lower in 2025 as compared to 2024 primarily due to higher profit over fixed tax benefits, including lower investment tax credits from solar, and storage plants placed into service or are forecasted to be placed into service during 2025 and lower Section 179D Energy Efficient Building deduction, offset by the effects of foreign earnings.
•Net Earnings Per Share: Net income increased due to the reasons described above. Basic and diluted earnings per share for the three months ended June 30, 2025 were $0.24, an increase of $0.14 per share compared to the same period of 2024.

Our results of operations for the six months ended June 30, 2025 are due to the following:
•Revenues: total revenues for the six months ended June 30, 2025 increased over 2024 primarily due to a $ 75 million, or 14%, increase in our project revenues attributed to the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects, and a $23.0 million, or 24% increase in energy asset revenue resulting from the continued growth of our operating portfolio.
•Cost of Revenues and Gross Profit: the increase in cost of revenues is primarily due to the increase in project revenues described above and higher depreciation expenses from the continued growth in our operating assets portfolio. Gross profit as a percentage of revenues remained stable.
•Selling, General and Administrative Expenses (“SG&A”): SG&A expenses for the six months ended June 30, 2025 increased from 2024 primarily due to increases in payroll and related benefits, restructuring charges and professional fees, partially offset by lower other miscellaneous charges and an additional gain of $1.4 million recognized in 2025 from the sale of an energy technology and advisory services company late in 2024.
•Other Expenses, Net: Other expenses, net for the six months ended June 30, 2025 increased over 2024 primarily due to higher interest expenses, net of $9.3 million related to an increase in the amount of energy asset financings and corporate debt outstanding and higher interest rates, partially offset by gains from foreign currency transactions of $4.4 million compared to losses of $1.7 million last year.
•Income Tax Benefit: the benefit for income taxes is based on various rates set by federal, state, provincial and local authorities and is affected by differences between financial accounting and tax reporting requirements. We expect the effective tax rate benefit will be lower in 2025 as compared to 2024 primarily due to higher profit over fixed tax benefits, including lower investment tax credits from solar, and storage plants placed into service or are forecasted to be placed into service during 2025 and lower Section 179D Energy Efficient Building deduction, offset by the effects of foreign earnings.
•Net Earnings Per Share: Net income increased due to the reasons described above. This year there is net income attributable to non-controlling interests and redeemable non-controlling interests compared to a loss in the prior year. Basic and diluted earnings per share for the six months ended June 30, 2025 were $0.14, an increase of $0.10 per share compared to the same period of 2024.

•North America Regions: revenues increased during the three months ended June 30, 2025 primarily due to increased energy assets revenue resulting from the continued growth of our operating portfolio, higher O&M and consulting revenue, partially offset by decreased project revenues. The increased revenues during the six months ended June 30, 2025 is primarily due to higher project revenues resulting from the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects and higher energy asset revenue.
•U.S. Federal: the decrease in revenue versus the prior year is primarily due to lower project revenue attributed to the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects and the reversal of previously recognized revenue as it was determined that the closing of a sale of a solar photovoltaic energy project was no longer probable.
•Renewable Fuels: revenues decreased during the three months ended June 30, 2025 primarily due to decreased project revenues resulting from the timing of revenue recognized based upon costs incurred to date relative to total expected costs, partially offset by increased energy asset revenues resulting from the continued growth of our operating portfolio. The increased revenues during the six months ended June 30, 2025 is primarily due to an increase in energy asset revenues resulting from the continued growth of our operating portfolio and increased production levels partially offset by lower project revenue.
•Europe: revenues increased primarily due to higher project revenues resulting from the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects primarily related to increased activity under our joint venture in Greece compared to the prior period.
•All Other: All other revenues decreased year-over-year primarily due to the divestiture of an energy technology and advisory services company in the fourth quarter of 2024.

•Europe: the increase is primarily due to the increased revenues noted above, partially offset by higher SG&A expenses.
•All Other: the decrease is primarily due to the divestiture of an energy technology and advisory services company in the fourth quarter of 2024.
•Unallocated corporate activity includes all corporate level selling, general and administrative expenses and other expenses not allocated to the segments. We do not allocate any indirect expenses to the segments. Corporate activity decreased primarily due to foreign currency transaction gains this year versus losses last year and an additional gain of $1.4 million recognized in 2025 from the sale of an energy technology and advisory services company late in 2024, partially offset by higher interest expenses, net.
Liquidity and Capital Resources
Overview
Since inception, we have funded operations primarily through cash flow from operations, advances from Federal ESPC projects, our senior secured credit facility, second lien term loan and various forms of other debt. See Note 8 “Debt and Financing Lease Liabilities” for additional information.
Working capital requirements can be susceptible to fluctuations during the year due to timing differences between costs incurred, the timing of milestone-based customer invoices and actual cash collections. Working capital may also be affected by seasonality, growth rate of revenue, long lead-time equipment purchase patterns, advances from Federal ESPC projects, and payment terms for payables relative to customer receivables.
We expect to incur additional expenditures in connection with the following activities:
•equity investments, project asset acquisitions, and business acquisitions that we may fund from time to time
•capital investment in current and future energy assets
•material, equipment, and other expenditures for large projects
We regularly monitor and assess our ability to meet funding requirements. We believe that cash and cash equivalents, working capital and availability under our revolving senior secured credit facility, combined with our right (subject to lender consent) to increase our revolving credit facility by $100.0 million, plus develop and sell asset transactions, sales of tax attributes, and our general access to credit and equity markets, will be sufficient to fund our operations through at least August 2026 and thereafter.
We continue to evaluate and take action, as necessary, to preserve adequate liquidity and ensure that our business can continue to operate and that we can meet our capital and debt service requirements. This may include limiting discretionary spending across the organization and re-prioritizing our capital projects amid times of political unrest, the duration of supply challenges, and the rate and duration of the inflationary pressures, and other events affecting our liquidity. For example, recent increases in inflation and interest rates have impacted overall market returns on assets. We have therefore been particularly prudent in our capital commitments over the past few quarters, ensuring that our assets in development continue to align with our hurdle rates.
Senior Secured Corporate Credit Facility
On January 23, 2025, we refinanced our term loan and revolving credit facility by entering into a sixth amended and restated senior secured credit agreement (“Restated Credit Agreement”) with the group of lenders thereto. The interest rate for borrowings is based on, at our option, either the Base Rate plus a margin of 0.75% to 1.75%, depending on our core leverage ratio; or the Term SOFR plus a margin of 1.75% to 2.75%, depending on our core leverage ratio. A commitment fee of between 0.25% and 0.375%, depending on our core leverage ratio, is payable quarterly on the undrawn portion of the revolver. As of June 30, 2025, the interest rates were 6.85% and 7.48% per annum for the term loan and revolving credit facility, respectively. At closing we paid $2.3 million in lenders fees and debt issuance costs. Proceeds from this agreement in the amount of $180.0 million and $13.0 million were used to pay the balance of our revolving credit facility and the outstanding portion of the senior secured term loan, respectively, at closing.
The Restated Credit Agreement replaced and extended the prior credit agreement dated March 4, 2022, and subsequently amended (the “Original Credit Agreement”). The Restated Credit Agreement refinanced the credit facilities under the Original Credit Agreement and replaced it with the following facilities:
•a $225.0 million revolving credit facility, maturing on December 28, 2028, and
•a $100.0 million term loan, maturing on December 28, 2028.
The revolver may be increased by up to an additional $100.0 million at our option if lenders are willing to provide such increased commitments, subject to certain conditions.

As of June 30, 2025, the balance on the senior secured term loans was $97.5 million, the balance on the senior secured revolving credit facility was $103.0 million, and we had funds available of $9.8 million.
Energy Asset Financing
Energy Asset Construction Facilities, Financing Facilities, and Term Loans
We have entered into a number of construction and term loan agreements for the purpose of constructing and owning certain renewable energy plants. The physical assets and the operating agreements related to the renewable energy plants are generally owned by wholly owned, single member “special purpose” subsidiaries of Ameresco. These construction and term loans are structured as project financings made directly to a subsidiary, and upon commercial operation and achieving certain milestones in the credit agreement, the related construction loan converts into a term loan. While we are required under generally accepted accounting principles (“GAAP”) to reflect these loans as liabilities on our condensed consolidated balance sheets, they are generally non-recourse and not direct obligations of Ameresco, Inc., except to the extent of completion guarantees and EPC contracts and certain equity contribution obligations under our August 2023 Construction Credit Facility.
Our project financing facilities contain various financial and other covenant requirements which include debt service coverage ratios and total funded debt to EBITDA, as defined in the facilities. Any failure to comply with the financial or other covenants of our project financings would result in inability to distribute funds from the wholly-owned subsidiary to Ameresco, Inc. or constitute an event of default in which the lenders may have the ability to accelerate the amounts outstanding, including all accrued interest and unpaid fees.
On April 30, 2025 we entered into a note purchase agreement and private shelf agreement which includes committed proceeds under series A notes of $78.0 million to finance a battery energy storage asset in development, with a maturity date of September 30, 2045, and a fixed interest rate of 6.72% per annum. Gross proceeds from the initial issuance on April 30, 2025 were $67.7 million and the remaining balance of $10.3 million was issued on June 27, 2025. The agreement also includes a 20-year term $300.0 million private shelf facility as well as the ability to issue series B notes on or before December 31, 2025. As part of this transaction, we signed a tax credit transfer agreement for the investment tax credits associated with the BESS asset. Upon the asset achieving commercial operations, we will receive payment for the ITC transfer and a $30.0 million prepayment on the note purchase agreement will be required.
During the six months ended June 30, 2025, we drew an additional $138.7 million and paid down $60.2 million on our August 2023 Construction Credit Facility. The Powin bankruptcy triggered a default under this facility, requiring us to move the project associated with the battery payment deposits we made to Powin out of this facility. We subsequently received a waiver effective July 31, 2025 of this default as well as of a default of certain lien provisions under the facility.
We also paid off our October 2012, Term Loan in the amount of $31.1 million, partially with $8.3 million in proceeds from our new $12.2 million May 2025, Term Loan and the remainder from working capital.
Other Financing Facilities and Financing Leases
During the six months ended June 30, 2025, we sold and leased back five energy assets for $18.9 million in cash proceeds under our master sale-leaseback agreements. During the three months ended June 30, 2025, we were default of certain lien provisions of this agreement. On June 30, 2025, we received a waiver of this default.
As of June 30, 2025, we were in default under our December 2020 Master Sale-leaseback agreement as we had failed to satisfy the historical coverage ratio under this agreement. On May 5, 2025, we received a waiver of this default.
Federal ESPC Liabilities
We have arrangements with certain third-parties to provide advances to us during the construction or installation of projects for certain customers, typically federal governmental entities, in exchange for our assignment to the lenders of our rights to the long-term receivables arising from the ESPCs related to such projects. These financings totaled $550.6 million as of June 30, 2025. Under the terms of these financing arrangements, we are required to complete the construction or installation of the project in accordance with the contract with our customer, and the liability remains on our condensed consolidated balance sheets until the completed project is accepted by the customer.
We are the primary obligor for financing received, but only until final acceptance of the work by the customer. At this point recourse to us ceases and the ESPC receivables are transferred to the investor. The transfers of receivables under these agreements do not qualify for sales accounting until final customer acceptance of the work, so the advances from the investors are not classified as operating cash flows. Cash draws that we received under these ESPC agreements were $35.4 million during the six months ended June 30, 2025, and are recorded as financing cash inflows. The use of the cash received under these arrangements is
38
Table of Contents

to pay project costs classified as operating cash flows and totaled $36.7 million during the six months ended June 30, 2025. Due to the manner in which the ESPC contracts with the third-party investors are structured, our reported operating cash flows are materially impacted by the fact that operating cash flows only reflect the ESPC contract expenditure outflows and do not reflect any inflows from the corresponding contract revenues. Upon acceptance of the project by the federal customer the ESPC receivable and corresponding ESPC liability are removed from our condensed consolidated balance sheets as a non-cash settlement.
Other
We issue letters of credit and performance bonds, from time to time, with our third-party lenders, to provide collateral.

Our service offering also includes the development, construction, and operation of small-scale renewable energy plants. Small-scale renewable energy projects, or energy assets, can either be developed for the portfolio of assets that we own and operate or designed and built for customers. Expenditures related to projects that we own are recorded as cash outflows from investing activities. Expenditures related to projects that we build for customers are recorded as cash outflows from operating activities as cost of revenues.
Cash Flows from Operating Activities
Our cash flows from operating activities during the six months ended June 30, 2025 decreased over the same period last year primarily due to increases in cash outflows of $156.9 million in accounts payable, accrued expenses and other current liabilities, $39.8 million in deferred revenue, and $41.9 million in prepaid expenses and other current assets, partially offset by increases in cash inflows of $46.3 million in unbilled revenue (costs and estimated earnings in excess of billings) due to the timing of when certain projects are invoiced when compared to the prior year period and $6.8 million in accounts receivable.
Cash Flows from Investing Activities
During the six months ended June 30, 2025 we made capital investments of $208.1 million in new energy assets and $10.1 million in major maintenance of energy assets compared to $227.4 million and $10.5 million, respectively, in 2024.
We currently plan to invest approximately $150 million to $200 million in additional capital expenditures during the remainder of 2025, principally for the construction or acquisition of new renewable energy plants, the majority of which we expect to fund with project finance debt.
Cash Flows from Financing Activities
Our primary sources of financing for the six months ended June 30, 2025 were proceeds from energy asset financings of $290.2 million, proceeds from long-term corporate debt financings of $100.0 million, net proceeds received from Federal ESPC projects and energy asset receivable financing arrangements of $35.2 million, partially offset by payments on long-term debt and debt fees of $176.5 million, and net payments on our senior secured revolving credit facility of $32.0 million.
Our primary sources of financing for the six months ended June 30, 2024 were proceeds from energy asset financings of $259.3 million, proceeds from long-term corporate debt financings of $100.0 million, net proceeds received from Federal ESPC projects and energy asset receivable financing arrangements of $125.4 million, net proceeds from our senior secured revolving credit facility of $34.9 million, contributions from a non-controlling interest of $30.8 million, partially offset by payments on long-term debt and debt fees of $213.0 million, and payments on seller’s promissory note of $29.4 million.

We currently plan additional project financings of approximately $100 million to $150 million during the remainder of 2025 to fund the construction or the acquisition of new renewable energy plants as discussed above.
Critical Accounting Estimates
Preparing our condensed consolidated financial statements in accordance with GAAP involves us making estimates and assumptions that affect reported amounts of assets and liabilities, net sales and expenses, and related disclosures in the accompanying notes at the date of our financial statements. We base our estimates on historical experience, industry and market trends, and on various other assumptions that we believe to be reasonable under the circumstances. However, by their nature, estimates are subject to various assumptions and uncertainties, and changes in circumstances could cause actual results to differ from these estimates, sometimes materially.
There have been no material changes in our critical accounting estimates from those disclosed in Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations of our 2024 Form 10-K. In addition, refer to Note 2 “Summary of Significant Accounting Policies” for updates to critical accounting policies.
Recent Accounting Pronouncements
See Note 2, “Summary of Significant Accounting Policies” for a discussion of recent accounting pronouncements.
Item 3. Quantitative and Qualitative Disclosures About Market Risk
As of June 30, 2025, there have been no significant changes in market risk exposures that materially affected the quantitative and qualitative disclosures as described in Item 7A to our 2024 Form 10-K.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our principal executive officer and principal financial officer, evaluated the effectiveness of our disclosure controls and procedures, as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, as of the end of the period covered by this quarterly report, or the evaluation date. Disclosure controls and procedures are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosures. Our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives, and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Our management, after evaluating the effectiveness of our disclosure controls and procedures as of the evaluation date, concluded that as of the evaluation date, our disclosure controls and procedures were effective at a reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes in our internal control over financial reporting during our most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
