Senior Secured Credit Facility

On February 16, 2024, a wholly owned subsidiary of ours entered into an amendment (the “Amendment”) to a syndicated, senior secured credit facility originally entered into with various lenders on April 20, 2021 (the “Initial Credit Facility”) which has previously been amended five times (as amended, the “Credit Facility”). Prior to the Amendment, the Credit Facility had commitments of $1.8 billion and matured on April 20, 2025. Prior to and after the Amendment, the Credit Facility is non-recourse to us and is secured by net cash flows from power purchase agreements and leases available to the subsidiary borrower after distributions to tax equity investors and payment of certain operating, maintenance and other expenses.

The Amendment amends certain terms of the Credit Facility, including:

•extending the maturity date to February 16, 2028;

•in the case of each lender (other than certain commercial paper conduit lenders (“CP Lenders”)), increasing the interest rate (i) for the period from the date of the Amendment to February 16, 2027 from the SOFR index + 215 basis points to such index + 265 basis points and (ii) for the period from and after February 16, 2027, from the SOFR index + 315 basis points to such index + 365 basis points;

•in the case of each CP Lender, revising the interest rate (i) for the period from the date of the Amendment to February 16, 2027 from the SOFR index + a margin of 215 basis points to the applicable commercial rate for such CP Lender + 235 basis points and (ii) for the period from and after February 16, 2027 from the applicable SOFR index + a margin of 315 basis points to the applicable commercial paper rate for such CP Lender + 335 basis points; and

•increasing total loan commitments available by $550.0 million, bringing the total commitments to $2.35 billion.
