Our debt and financing lease liabilities are comprised of the following:
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.
At June 30, 2026, $435,615 was outstanding under this facility, net of unamortized debt discount and issuance costs.
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.
Other Financing Facilities
These facilities are accounted for as failed sale-leasebacks and are classified as long-term financing facilities.
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.
We sold and leased back two energy assets for $4,560 in cash proceeds under this facility during the six months ended June 30, 2026.
Surety-Backed Letters of Credit
We also have surety-backed letters of credit with termination dates through 2027 and par value of $16,165.
