NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(In thousands) (Unaudited)
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, 2026 are not necessarily indicative of results which may be expected for the full year. The December 31, 2025 condensed 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, 2025, included in our annual report on Form 10-K (“2025 Form 10-K”) filed with the Securities and Exchange Commission on March 3, 2026.
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, such as tariffs, supply chain challenges, geopolitical instability and conflicts in Ukraine and the Middle East, evolving relations between the U.S. and China, and other geopolitical tensions have restricted the global supply of, and raised prices for, supplies needed for our business and 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 2025 Form 10-K. We have included certain updates to those policies below.

Recent Accounting Pronouncements
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.
Business Combinations (Topic 805) and Consolidation (Topic 810) - Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity
In May 2025, the FASB issued ASU 2025-03, Business Combinations (Topic 805) and Consolidation (Topic 810) - Determining the Accounting Acquirer in the Acquisition of a Variable Interest Entity to enhance the ability to compare business combinations that do and do not involve variable interest entities by identifying the accounting acquirer. ASU 2025-03 is effective for fiscal years beginning after December 15, 2026, including interim reporting periods within those fiscal years. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.
Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses for Accounts Receivable and Contract Assets
In July 2025, the FASB issued ASU 2025-05, Financial Instruments - Credit Losses (Topic 326) Measurement of Credit Losses for Accounts Receivable and Contract Assets to address challenges encountered when applying the guidance in Topic 326, Financial Instruments—Credit Losses, to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606, Revenue from Contracts with Customers. ASU 2025-05 is effective for fiscal years beginning after December 15, 2025, and interim periods within those fiscal years. We adopted this new accounting standard effective January 1, 2026 and the adoption did not have a material impact on our condensed consolidated financial statements.
Derivatives and Hedging (Topic 815) - Hedge Accounting Improvements
In November 2025, the FASB issued ASU 2025-09, Derivatives and Hedging (Topic 815) - Hedge Accounting Improvements to clarify certain aspects of the guidance on hedge accounting and to address several incremental hedge accounting issues arising from the global reference rate reform initiative. ASU 2025-09 is effective for fiscal years beginning after December 15, 2026, and interim periods within those fiscal years. We are currently evaluating the impact that adopting this new accounting standard would have on our condensed consolidated financial statements.

The increase in contract assets for the six months ended June 30, 2026 was primarily due to revenue recognized of $641,749 , as well as reclassifications primarily from contract liabilities as a result of the timing of customer payments, offset by billings of $572,891 . The decrease in contract liabilities was primarily driven by revenue recognized, offset 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 the recognition of revenue as performance obligations were satisfied exceeded advance payments and reclassifications. For the six months ended June 30, 2026, we recognized revenue of $215,430 and billed $183,745 to customers that had balances which were included in contract liabilities at December 31, 2025.
Performance Obligations
Our remaining performance obligations (“backlog”) represent the unrecognized revenue value of our contract commitments. At June 30, 2026, we had contracted backlog of $3,820,481 of which approximately 32 % 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 $6,470 and $4,045 were recognized in our condensed consolidated statements of operations on projects that converted to customer contracts during the three months ended June 30, 2026 and 2025, respectively. Project development costs of $11,320 and $8,481 were recognized in our condensed consolidated statements of operations on projects that converted to customer contracts during the six months ended June 30, 2026 and 2025, respectively.
No impairment charges in connection with our project development costs were recorded during the six months ended June 30, 2026 and 2025.
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.

The estimated net present value of this commitment totals $40,335 as of June 30, 2026. 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 lease liability will be recorded, which we estimate to be later in 2026.
We have a future lease commitment for a project lease in Illiopolis, IL. The estimated net present value of this commitment totals $4,509 . This new lease agreement was executed and the lease will commence July 1, 2026 and will continue for 20 years upon commercial operation, which we estimate to be in mid 2027.
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.

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, 2026, the interest rates were 6.23 % and 6.27 % 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
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
On March 30, 2026, we entered into amendment number 2 to the Restated Credit Agreement, and the term loan was increased by $45,000 , under a provision that allows us to increase the facility by up to an additional $100,000 at Ameresco’s option if lenders are willing to provide such increased commitments, subject to certain conditions. Following the amendment, $55,000 of remaining accordion capacity is available, subject to lender commitments and the terms of the credit agreement. Quarterly

principal payments increased to $1,812 . No other terms were changed with this amendment. As part of the exercise of the accordion feature, we paid $41,000 on the revolving credit facility and $1,085 for accrued interest on the term loan. Net proceeds for the term loan were $2,784 and debt issuance costs totaled $131 .
October 2022, Financing Facility, 8.75 %, due September 26, 2040
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.
On September 26, 2025 we entered into an amendment to modify the May 27, 2025 omnibus amendment. This amendment included advances of $25,500 related to an expansion project and $15,653 related to a true-up payment in connection to the removal of an IRR residual income requirement. The interest rate is now fixed at 8.75 % and the maturity date changed from August 31, 2039 to September 26, 2040.
On February 3, 2026, we entered into an omnibus amendment as part of moving two projects out of a construction credit facility and under this facility. The transaction added $99,900 to the facility for the two projects, of which $97,759 was used to pay off the projects under the construction facility. No other terms were changed with this amendment.

June 2020, Construction Credit Facility, 5.25 %, due March 31, 2027
During the six months ended June 30, 2026, we entered into an amendment to extend this revolver, and the current maturity date is March 31, 2027.
As of June 30, 2026, $20,337 was outstanding under this facility and $79,663 was available for borrowing.
August 2023 Variable Rate Construction Facility 8.48 %, due December 2027
On June 30, 2026, we entered into an amendment to extend the accordion exercise period of this construction facility through July 15, 2026 and decrease the accordion option from $100 million to $50 million and the aggregate commitment under the agreement from $500 million to $450 million. On June 30, 2026, we exercised the accordion option, increasing the borrowing capacity from $400 million to $450 million.
As of June 30, 2026, $250,860 was outstanding under this facility, net of unamortized debt discount and issuance costs.
See Note 13 regarding a $57,942 payment made on this construction facility in connection with the closing of a joint venture transaction on May 12, 2026.

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, 2026, we entered into an amended and restated participation agreement which extended the participation date from March 31, 2026 to March 31, 2027. During the six months ended June 30, 2026, we were in default of certain lien provisions of this agreement on three facilities. In June 2026, we received waiver of these defaults which are valid until August 14, 2026, August 30, 2026, and December 30, 2026.

9. INCOME TAXES
We recorded a tax provision for income taxes of $137 for the three months ended June 30, 2026 and a benefit of $2,900 for the three months ended June 30, 2025, respectively. We recorded an income tax benefit of $3,047 and $1,712 for the six months ended June 30, 2026 and 2025, respectively.
The effective tax rate provision was 0.7 % for three months ended June 30, 2026, compared to the effective tax rate benefit of 23.0 % for the three months ended June 30, 2025. The effective tax rate benefit was 123.0 % for the six months ended June 30, 2026, compared to the effective tax rate benefit of 20.9 % for the six months ended June 30, 2025.
The principal reason for the higher effective rate for the three months ended June 30, 2026 is higher income offset by higher investment tax credits forecasted on assets to be placed in service during 2026 versus lower income in 2025 as well as lower investment tax credits earned in 2025. The principal reason for the lower effective rate for the six months ended June 30, 2026 is due to higher investment tax credits forecasted on assets to be placed into service during 2026 versus 2025.
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 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 parties are continuing to dispute the scope and timing of SCE’s final payment obligations and whether liquidated damages should apply. Our view continues to be that SCE is obligated to make the final payments under the SCE Agreement and liquidated damages should not be applied. If we fail to come to an agreement with SCE on these matters, 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. 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
The August 4, 2023 purchase and sale agreement with BCE includes a potential earn-out that could be earned if the projects achieve specified value thresholds in certain phase 2 projects, each of which is very early in development, or if milestones are achieved on other future projects that are not yet started. The total earn-out is limited to $40,000 over a seven-year period beginning on January 12, 2024. We will record a liability for the phase 2 earn-out payments when the amounts are probable and

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, of which $10,000 and are recorded within other assets and $16,683 recorded in energy assets, net in the accompanying condensed consolidated balance sheets. We are actively monitoring the proceedings, and the range of cash loss is between $0 and $26,683 . The bankruptcy proceedings are ongoing and 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.
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:

The fair value of our interest rate swaps was determined using cash flow analysis on the expected cash flow of the contract in combination with observable market-based inputs, including interest rate curves and implied volatility. As part of this valuation, we considered the credit ratings of the counterparties to the interest rate swaps to determine if a credit risk adjustment was required.
The fair value of our make-whole provisions was determined by comparing them against the rates of similar debt instruments under similar terms without a make-whole provision obtained from various highly rated third-party pricing sources.
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, 2026 and the year ended December 31, 2025.
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

Neogenyx Fuels LLC
On May 4, 2026, Ameresco, through certain of its subsidiaries, entered into a contribution and equity purchase agreement (the “Contribution Agreement” and, the transactions contemplated thereby, the “JV Transaction”) with an affiliate of HA Sustainable Infrastructure Capital, Inc., a Delaware corporation (“HASI” and, such affiliate, “JV Investor”) to form a new joint venture, Neogenyx Fuels LLC, a Delaware limited liability company (the “Joint Venture” or “Neogenyx”). The JV Transaction closed on May 12, 2026.
The JV Transaction constituted a reconsideration event under ASC 810, under which we concluded that Neogenyx Fuels LLC is a variable interest entity, and we are the primary beneficiary. Accordingly, following the formation, Ameresco retains control over Neogenyx. We recognized the decrease in ownership of Neogenyx as a non-controlling interest. The difference between the cash received and the non-controlling interest was recognized as an adjustment to additional paid-in capital. Transactions costs attributable to the security issuance were recognized as a reduction to additional paid-in capital.
The Contribution Agreement provided that, among other things:
•Ameresco and certain of its subsidiaries transferred to the Joint Venture the equity interests of the subsidiaries and certain other assets comprising Ameresco’s existing biogas business (the “Business”), together with related assumed liabilities, in exchange for Class A units of the Joint Venture (the “Class A Units”), representing a 70 % equity interest of the Joint Venture; and
•JV Investor committed to invest a total of $400,000 in the Business, in exchange for Class B units of the Joint Venture (the “Class B Units”), representing a 30 % equity interest of the Joint Venture. Of the $400,000 investment (i) $233,800 was paid to Ameresco at closing as consideration for the Business, of which $57,942 , was used to pay towards the August 2023 Variable Rate Construction Facility and approximately $5,371 was used to pay fees, and (ii) the remaining $166,200 will be contributed to the Joint Venture over a period of time to fund the Joint Venture.
An amended and restated limited liability company agreement of the Joint Venture includes the key terms related to quarterly distributions, liquidating distributions, right of first offer, drag-along and tag-along rights, call options, and management and governance provisions.
Neogenyx is reported within our Renewable Fuels segment which is consistent with our historical presentation prior to the JV Transaction.
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 operations.

14. REDEEMABLE NON-CONTROLLING INTERESTS
Our subsidiaries with membership interests in the investment funds we formed had 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 fund also included 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.
The call options were exercisable beginning on the date that specified conditions are met for each respective fund. The call option period for our only active investment fund began in May 2026. In June 2026 we finalized our purchase of the investor’s membership interest for $622 in cash and reclassified the remaining redeemable non-controlling interest balance to paid-in capital to reflect the additional contribution from us to our wholly-owned subsidiary.

We initially record our redeemable non-controlling interests at fair value on the date of acquisition and subsequently adjust to redemption value. At December 31, 2025, the remaining redeemable non-controlling interest was reported at its carrying value, as the carrying value at each reporting period was greater than the estimated redemption value. At June 30, 2026, we have no investment funds remaining.

This Quarterly Report on Form 10-Q contains “forward-looking statements” within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Statements that do not relate strictly to historical or current facts are forward-looking statements. Without limiting the generality of the foregoing, forward-looking statements contained herein specifically include statements that refer to our expectations as to the future growth of our business and associated expenses; our expectations as to revenue generation; the future availability of borrowings under our revolving credit facility; the expected future growth of the market for energy efficiency and renewable energy solutions; our backlog, awarded projects and recurring revenue and the timing of such matters; our expectations as to financing and acquisition activity; the impact of any restructuring; the uses of future earnings; the expected energy and cost savings of our projects; the expected energy production capacity of our renewable energy plants; the impact of supply chain disruptions, shortage and cost of materials and labor, the impact of macroeconomic and geopolitical challenges; our expectations related to our agreement with SCE and associated liquidated damages; and other characterizations of future events or circumstances are forward-looking statements. Forward looking statements are often, but not exclusively, identified by the use of words such as “may,” “will,” “expect,” “believe,” “anticipate,” “plan,”“intend,” “could,” “estimate,” “target,” “project,” “predict” or “continue,” and similar expressions or variations. These forward-looking statements are based on current expectations and assumptions that are subject to risks, uncertainties and other factors that could cause actual results and the timing of certain events to differ materially and adversely from future results expressed or implied by such forward-looking statements. Risks, uncertainties, and factors that could cause or contribute to such differences include, but are not limited to, those discussed in the section titled “Risk Factors,” set forth in Part I, Item 1A of our 2025 Form 10-K. Subsequent events and developments may cause our views to change. However, while we may elect to update these forward-looking statements at some point in the future, we have no current intention of doing so and undertake no obligation to do so except to the extent required by applicable law. You should, therefore, not rely on these forward-looking statements as representing our views as of any date subsequent to the date of this Quarterly Report on Form 10-Q.

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.
31
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.
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 for energy efficiency and renewable energy, and a decline in such support or the imposition of additional taxes, tariffs, duties or other assessments on renewable energy or the equipment necessary to generate or deliver it, could harm our business” and “Compliance with environmental laws could adversely affect our operating results” in Item 1A, Risk Factors in our 2025 Form 10-K.
Neogenyx Fuels LLC Joint Venture Transaction
On May 4, 2026, we entered into a contribution and equity purchase agreement with an affiliate of HA Sustainable Infrastructure Capital and an affiliate thereof (“HASI”) to combine our biogas business into a new joint venture, Neogenyx Fuels LLC. At closing on May 12, 2026, we contributed our existing biogas operations and related assets and liabilities in exchange for a 70% equity interest, while HASI acquired a 30% interest through a $400 million cash commitment. Of this amount, (i) $233,800 was paid to Ameresco at closing, of which $57,942, was used to pay existing project-level debt and approximately $5,371 was used to pay fees, and (ii) a portion of the remaining $166,200 was contributed to the joint venture at closing and the remainder thereof will be contributed over a period of time to fund the joint venture.
Following the closing, we are consolidating the joint venture into our financial statements.
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, geopolitical instability and conflicts in Ukraine and the Middle East, evolving relations between the U.S. and China, and other geopolitical tensions. These conflicts together with import duties, tariffs and other import restrictions, including the Uyghur Forced Labor Protection Act, have restricted the global supply of, and raised 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, 2026, 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, 2026. 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.
We believe the increasing demand for electricity, rising oil and utility rates, and growing grid instability, are driving demand for our energy infrastructure and other solutions. However, this increased demand may increase the competition we face and we may also face an increased risk in completing larger more complex projects.
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.
32
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 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 2025 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. The parties are continuing to dispute the scope and timing of SCE’s final payment obligations and whether liquidated damages should apply. Our view continues to be that SCE is obligated to make the final payments under the SCE Agreement and liquidated damages should not be applied. If we fail to come to an agreement with SCE on these matters, 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
We recorded stock-based compensation expense, including expenses related to the estimated achievement of the performance metrics of performance-based stock options (“PSOs”) granted during the year ended December 31, 2025, and our employee stock purchase plan. During the six months ended June 30, 2026, we granted 620,200 common stock options and 128,160 restricted stock units (“RSUs”) to certain employees under our 2020 Plan. Our unrecognized stock-based compensation expense was $30.0 million at June 30, 2026, compared to $24.8 million at December 31, 2025, 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.

The following table presents our backlog:

12-month O&M backlog | $ | 117,527 | $ | 101,272 | |||||||
Total project backlog: Total project backlog represents energy efficiency projects that are active within our sales cycle and include awarded and contracted backlog. 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: For our more traditional projects, 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 for our more traditional project to fully-contracted backlog. It may take longer, as it depends on the size and complexity of the project. A growing portion of our backlog represents projects in development for data centers, which have different milestones within the sales cycle compared to our traditional projects. These data center projects are added to our awarded backlog when we are under an exclusive arrangement with a data center developer or land owner, and have made meaningful progress in terms of site control, interconnection and the offtake arrangement, among other development activities. Given the development status of these projects, we may choose to include only a portion of the estimated total contract value in our awarded backlog while development progresses and scopes are finalized. These projects represent a new end market for Ameresco, however we currently believe that the average sales cycle of these projects will be consistent with our traditional projects.
Contracted backlog: 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. Consistent with our traditional projects, data center project will also move to fully-contracted backlog after the customer and Ameresco agree to the terms of either an offtake or EPC agreement and the agreements are executed.
O&M backlog: 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.
12-month backlog: 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” and other risk factors related to our ability to convert backlog into revenue in Item 1A, Risk Factors in our 2025 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 $1.7 billion and $2.3 billion, net of amounts attributable to a non-controlling interest at June 30, 2026 and 2025, 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, 2026 are due to the following:
•Revenues: total revenues for the three months ended June 30, 2026 increased over 2025 primarily due to a $22.8 million, or 6%, 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, primarily in U.S. Federal and Europe segments. The increase is in part attributed to a $13.0 million, or 21% increase in energy asset revenue resulting from the growth of our operating asset portfolio and an $8.2 million, or 29%, increase in operations and maintenance revenue due to continued additions of new long-term contracts.
•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 increased primarily in our energy asset and operations and maintenance businesses due in part to growth in these businesses as noted above, production tax credits earned, and the benefit of annual price increases on relatively stable costs on certain operations and maintenance contracts.
•Selling, General and Administrative Expenses (“SG&A”): SG&A expenses for the three months ended June 30, 2026 increased from 2025 primarily due to an increase in professional fees of $1.8 million and payroll and benefit costs of $0.7 million, offset in part by a decrease in restructuring costs.
•Interest Expense and Interest Income, Net: increased $5.1 million primarily due to increases in the amount of energy asset financings and corporate debt outstanding.
•Other Expenses (Income), Net: Other expenses (income), net for the three months ended June 30, 2026 is lower than 2025 primarily due to the impact of foreign currency transaction gains and losses. In the three months ended June 30, 2026 we recognized a loss of $0.0 million compared to gains of $3.0 million in the same period last year.
•Income Tax (Benefit) Expense: 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. The higher effective rate for the three months ended June 30, 2026 is primarily due to higher income offset by higher investment tax credits forecasted on assets to be placed in service during 2026 versus lower income in 2025 as well as lower investment tax credits earned in 2025. We expect a higher effective tax rate benefit in 2026 as compared to 2025 primarily attributable to our plan generate and hold more investment tax credits on energy assets placed into service during 2026.
35
Management continues to evaluate the market conditions for opportunities to monetize investment tax credits on favorable terms.
•Net Income and Earnings Per Share: Net income decreased due to the reasons described above as well as the impact of gains attributable to non-controlling interest and redeemable non-controlling interest of 10.2 million. Basic and diluted earnings per share for the three months ended June 30, 2026 was $0.18, a decrease of $0.06 per share basic and diluted compared to the same period of 2025.

Our results of operations for the six months ended June 30, 2026 are due to the following:
•Revenues: total revenues for the six months ended June 30, 2026 increased over 2025 primarily due to a $61.8 million, or 10%, increase in our project revenues attributed to continued growth and expansion in our project business in Europe, the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects, principally in our Federal and Europe segments, as well as the impact of the 2025 reversal of previously recognized revenue on a Federal solar photovoltaic energy project that was determined that the closing of the sale was not probable.. The increase is in part attributed to a $13.6 million, or 26% in operations and maintenance revenue due to continued additions of new long-term contracts, and a $17.0 million, or 14% increase and energy asset revenue resulting from the growth of our operating asset portfolio.
•Cost of Revenues and Gross Profit: the increased 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 increased primarily due to a more favorable mix of higher-margin projects as well as growth in our operations and maintenance business.
•Selling, General and Administrative Expenses (“SG&A”): SG&A expenses for the six months ended June 30, 2026 increased from 2025 primarily due to increases in payroll and related benefits of $4.5 million, increases in professional fees of $3.2 million, as well as the effect of an additional gain of $1.4 million recognized in 2025 from the sale of an energy technology and advisory services company late in 2024.
•Interest Expense and Interest Income, Net: increased $10.4 million primarily due to increases in the amount of energy asset financings and corporate debt outstanding.
•Other Expenses (Income), Net: Other expenses (income), net for the six months ended June 30, 2026 increased over 2025 primarily due to an increase in loss from foreign currency transactions of $1.0 million compared to gains of $4.4 million in the same period 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. The lower effective rate for the six months ended June 30, 2026 is primarily due to higher investment tax credits forecasted on
36
assets to be placed into service during 2026 versus 2025.We expect a higher effective tax rate benefit in 2026 as compared to 2025 primarily attributable to our plan to generate and hold more investment tax credits on energy assets placed in service during 2026.
•Net Income (Loss) and Earnings Per Share: Net income (loss) decreased to a loss due to the reasons described above. Basic and diluted loss per share for the six months ended June 30, 2026 was $0.16, a decrease of $0.30 per share basic and diluted compared to the earnings per share in the same period of 2025.

•North America Regions: the decrease in revenue 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, partially offset by increased operations and maintenance revenue attributed to continued additions of new long-term contracts as well as increased energy asset revenue resulting from the growth of our operating asset portfolio.
•U.S. Federal: the increase in revenue during the three and six months ended June 30, 2026 is primarily due to increased project revenue attributed to the timing of revenue recognized based upon costs incurred to date relative to total expected costs on active projects as well as increased operations and maintenance revenue attributed to continued additions of new long-term contracts as well as increased energy asset revenue resulting from the growth of our operating asset portfolio. The increase in revenue during the six months ended June 30, 2026 is also due to the impact in 2025 of the reversal of previously recognized revenue on a solar photovoltaic energy project that was determined that the closing of the sale was not probable.
•Renewable Fuels: the increase in revenue is primarily due to increased energy assets revenue resulting from the continued growth of our operating asset portfolio as well as increased project revenues resulting from the timing of revenue recognized based upon costs incurred to date relative to total expected costs.
•Europe: the increase in revenue 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 primarily related to increased activity under our joint ventures in Greece and Romania compared to the prior period.
•All Other: All other revenues decreased year-over-year primarily due to lower sales in our integrated PV line of business due in part to seasonality.

•North America Regions: the decrease is primarily due to a decrease in unrealized gains from derivatives, a decrease in other income, lower gross profit due to lower project revenue, and the impact of lower-margin project mix in the three months ended June 30, 2026, partially offset by a higher-margin project mix in the six months ended June 30, 2026.
•U.S. Federal: the increase is primarily due to higher gross profit primarily due to the benefit of annual price increases on relatively stable costs for certain operations and maintenance contracts and an increase in unrealized gains from derivatives, partly offset by increased operating expenses from legal costs compared to the prior period.
•Renewable Fuels: the increase during the three months ended June 30, 2026 is primarily due to additional assets placed into service as well as production tax credits earned resulting in higher gross profit and profit margins, offset by higher interest expenses. The increase in loss during the six months ended June 30, 2026 is primarily due to lower gross margins attributed to energy asset production delays primarily due to weather impacts in the first quarter of the year, increased depreciation expense due to growth in our operating portfolio, and higher interest expenses.
•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 decreased revenues noted above.
•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 expenses increased primarily due to higher net interest expense and foreign currency transaction losses this year versus gains last year, increased stock compensation and insurance costs in 2026 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.
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 “Energy Asset Financing” below) and equity.
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 2027 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
38
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.
Of the $400 million cash commitment from HASI related to the new joint venture, Neogenyx Fuels LLC, which closed on May 12, 2026, (i) $233,800 was paid to Ameresco at closing, of which $57,942, was used to pay existing project-level debt and approximately $5,371 was used to pay fees, and (ii) a portion of the remaining $166,200 was contributed to the joint venture at closing. The remainder thereof will be contributed over a period of time to fund the joint venture, which funds are being used for strategic opportunities, working capital, and deleveraging throughout the year. See Neogenyx Fuels transaction in Key Factors and Trends above for further details.
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. 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. As of June 30, 2026, the interest rates were 6.23% and 6.27% per annum for the term loan and revolving credit facility, respectively.
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.
On March 30, 2026, we entered into amendment number 2 to the Restated Credit Agreement, and the term loan was increased by $45.0 million, under a provision that allows us to increase the facility by up to an additional $100.0 million at Ameresco’s option if lenders are willing to provide such increased commitments, subject to certain conditions. Following the amendment, $55 million of remaining accordion capacity is available, subject to lender commitments and the terms of the credit agreement. Quarterly principal payments increased to $1.8 million. No other terms were changed with this amendment. As part of the transaction, we paid $41.0 million on the revolving credit facility and $1.1 million for accrued interest on the term loan. Net proceeds for the term loan were $2.8 million.
As of June 30, 2026, the balance on the senior secured term loans was $136.9 million, the balance on the senior secured revolving credit facility was $153.0 million, and we had funds available of $42.8 million.
Energy Asset Financing
Energy Asset Construction and Operating 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.
39
On May 27, 2025 we entered into an omnibus amendment to our October 2022, Financing Facility as part of a tax credit transfer agreement for investment tax credits. The amendment required a $7.0 million principal payment, which was made during the three months ended June 30, 2025. On September 26, 2025 we entered into an amendment to modify the May 27, 2025 omnibus amendment. This amendment included advances of $25.5 million related to an expansion project and $15.7 million related to a true-up payment in connection to the removal of an IRR residual income requirement. The interest rate is now fixed at 8.75% and the maturity date changed from August 31, 2039 to September 26, 2040. On February 3, 2026, we entered into an omnibus amendment as part of moving two projects out of a construction credit facility and under this facility. The transaction added $99.9 million to the facility for the two projects, of which $97.8 million was used to pay off the projects under the construction facility. No other terms were changed with this amendment. At June 30, 2026, $435.6 million was outstanding under this facility, net of unamortized debt discount and issuance costs.
During the six months ended June 30, 2026, we entered into an amendment to extend our June 2020, Construction Credit Facility, and the current maturity date is March 31, 2027. As of June 30, 2026, $20.3 million was outstanding under this facility and $79.7 million was available for borrowing.
On June 30, 2026, we entered into an amendment to extend the accordion exercise period through July 15, 2026 and decrease the accordion option from $100 million to $50 million and the aggregate commitment under the agreement from $500 million to $450 million. On June 30, 2026, we exercised the accordion option, increasing the borrowing capacity from $400 million to $450 million.
Other Financing Facilities and Financing Leases
During the six months ended June 30, 2026, we sold and leased back two energy assets for $4.6 million in cash proceeds under our August 2018 Master Sale-leaseback. During the six months ended June 30, 2026, we entered into an amended and restated participation agreement which extended the participation date from June 30, 2026 to March 31, 2027. During the six months ended June 30, 2026, we were in default of certain lien provisions of this agreement. In June 2026, we received waiver of these defaults which are valid until August 14, 2026, August 30, 2026, and December 30, 2026.
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 $528.0 million as of June 30, 2026. 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 $48.1 million during the six months ended June 30, 2026, and are recorded as financing cash inflows. The use of the cash received under these arrangements is to pay project costs classified as operating cash flows and totaled $24.7 million during the six months ended June 30, 2026. 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, 2026 decreased over the same period last year primarily due to increases in cash outflows of $120.2 million in unbilled revenue, $8.3 million in deferred revenue and $8.7 million in accounts receivable, offset by increases in cash inflows of $55.0 million in accounts payable, accrued expenses and other current liabilities due to the timing of payments related to project activity compared to the prior year period and $29.4 million in prepaid expenses.
Cash Flows from Investing Activities
During the six months ended June 30, 2026 we made capital investments of $213.2 million in new energy assets and $15.9 million in major maintenance of energy assets compared to $208.1 million and $10.1 million, respectively, in 2025.
We currently plan to invest approximately $120 million to $170 million in additional capital expenditures during the remainder of 2026, principally for the construction or acquisition of new renewable energy plants, the majority of which we expect to fund with project finance debt and tax transfers. We expect that approximately $50 million to $75 million of that total will be incurred by the Neogenyx Fuels joint venture and funded by HASI’s capital commitments as well as project finance debt and tax transfers.
Cash Flows from Financing Activities
Our primary sources of financing for the six months ended June 30, 2026 were proceeds from energy asset financings of $235.1 million, contributions from non-controlling interests related to the Neogenyx Fuels joint venture of $228.4 million, proceeds from long-term corporate debt financings of $45.0 million, net proceeds received from Federal ESPC projects and energy asset receivable financing arrangements of $47.7 million, partially offset by payments on long-term debt and debt fees of $210.6 million including approximately $58.0 million of project financing debt repaid in connections with the Neogenyx Fuels joint venture transaction.
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, contributions from a non-controlling interest of $3.8 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.
We currently plan additional project financings of approximately $100 million during the remainder of 2026 to fund the construction or the acquisition of new renewable energy plants as discussed above, including amounts we plan to raise for energy assets in the Neogenyx Fuels joint venture.
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,
41
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 2025 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, 2026, 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 2025 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.

PART II - OTHER INFORMATION
Item 1. Legal Proceedings
In the ordinary conduct of our business, we are subject to periodic lawsuits, investigations, and claims. Although we cannot predict with certainty the ultimate resolution of such lawsuits, investigations and claims against us, we do not believe that any currently pending or threatened legal proceedings to which we are a party will have a material adverse effect on our business, results of operations or financial condition.
For additional information about certain proceedings, please refer to Note 10, Commitments and Contingencies, to our condensed consolidated financial statements included under Part I, Item 1 of this Quarterly Report on Form 10-Q, which is incorporated into this item by reference.
Item 1A. Risk Factors
Our business is subject to numerous risks, a number of which are described below and under “Risk Factors” in Part I, Item 1A of our 2025 Form 10-K.
You should carefully consider these risks together with the other information set forth in this report, which could materially affect our business, financial condition and future results. The risks described in Part I, Item 1A of our 2025 Form 10-K are not the only risks we face. Risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition, and operating results.
Item 2. Unregistered Sales of Equity and Use of Proceeds
Stock Repurchase Program
We did not repurchase any shares of our common stock under our stock repurchase program authorized by the Board of Directors on April 27, 2016 (the “Repurchase Program”) during the three months ended June 30, 2026. Under the Repurchase Program, we are authorized to repurchase up to $17.6 million of our Class A common stock. As of June 30, 2026, there were shares having a dollar value of approximately $5.7 million that may yet be purchased under the Repurchase Program.
Item 5. Other Information
Director and Officer Trading Arrangements
A portion of the compensation of our directors and officers (as defined in Rule 16a-1(f) under the Exchange Act) is in the form of equity awards and, from time to time, directors and officers engage in open-market transactions with respect to the securities acquired pursuant to such equity awards or other shares of Class A common stock held by such individuals. Transactions in our securities by directors and officers are required to be made in accordance with our insider trading policy, which requires that the transactions be in accordance with applicable U.S. federal securities laws that prohibit trading while in possession of material nonpublic information. Rule 10b5-1 under the Exchange Act provides an affirmative defense that enables directors and officers to prearrange transactions in a company’s securities in a manner that avoids concerns about initiating transactions while in possession of material nonpublic information.
