Item 1.01. Entry into a Material Definitive Agreement.

On May 29, 2025, Sunnova Energy International Inc. (the “Company”) and the other parties to the Forbearance Agreement (as defined below) agreed by email correspondence to an extension (the “Amendment”) of that certain Forbearance Agreement, dated as of May 2, 2025 (as amended, the “Forbearance Agreement”), by and among the Company, Sunnova Energy Corporation (“SEC”), Sunnova Intermediate Holdings, LLC and certain beneficial holders or investment managers or advisors for such beneficial holders (collectively, the “Supporting Holders”) of SEC’s 11.750% Senior Notes due 2028 (the “11.750% Notes”) and SEC’s 5.875% Senior Notes due 2026 (the “5.875% Notes” and, together with the 11.750% Notes, the “Notes”), relating to the Notes.

As previously announced, the Company elected to defer making an interest payment on the 11.750% Notes of approximately $23.5 million due on April 1, 2025 (the “Specified Default”) and enter the 30-day grace period under the indenture governing the 11.750% Notes (the “11.750% Notes Indenture”), which expired on May 1, 2025. Pursuant to the 11.750% Notes Indenture, a failure to make the interest payment by the expiration of the grace period constitutes an “Event of Default” under such indenture, which would entitle the trustee under the 11.750% Notes Indenture or the holders of at least 30% in aggregate principal amount of the outstanding 11.750% Notes to accelerate the maturity thereof. An Event of Default under the 11.750% Notes Indenture causes a cross-default under the indenture governing the 5.875% Notes (the “5.875% Notes Indenture” and such default, the “Cross-Default”), which would entitle the trustee under such indenture or the holders of at least 30% in aggregate principal amount of the outstanding 5.875% Notes to accelerate the maturity thereof.

As previously disclosed in the Current Report on Form 8-K filed on May 2, 2025, the Forbearance Agreement provided that, from May 2, 2025 until May 8, 2025, or the occurrence of another Event of Termination (as defined in the Forbearance Agreement) (the “Forbearance Period”), the Supporting Holders would (i) forbear from exercising any of their rights and remedies, including with respect to an acceleration, under 5.875% Notes Indenture or 11.750% Notes Indenture, as applicable, or applicable law with respect to the Specified Default and the Cross-Default and (ii) in the event that the applicable trustee or any holder or group of holders declares the Notes to be due and payable immediately (an “Acceleration”) during the Forbearance Period, to deliver written notice to the applicable trustee to rescind such Acceleration and its consequences and take all other action in their power to cause such Acceleration to be rescinded and annulled. In addition, during the Forbearance Period, each Supporting Holder (severally and not jointly) agreed that it (individually or collectively) will not deliver any notice or instruction to the applicable trustee directing the applicable trustee to exercise during the Forbearance Period any of the rights and remedies under 5.875% Notes Indenture or 11.750% Notes Indenture, as applicable, or applicable law with respect to the Specified Default and the Cross-Default. During the Forbearance Period, each of the Supporting Holders is prohibited from transferring the 5.875% Notes or 11.750% Notes, as applicable, except to a party who is already a Supporting Holder or who, prior to such transfer, agrees to be bound by all of the terms of the Forbearance Agreement.

Further, as previously disclosed in the Current Report on Form 8-K filed on May 8, 2025, the Company and the other parties to the Forbearance Agreement extended the Forbearance Period until the earlier of (i) May 15, 2025 and (ii) the occurrence of another Event of Termination, and as previously disclosed in the Current Report on Form 8-K filed on May 16, 2025, the Company and the other parties to the Forbearance Agreement further extended the Forbearance Period until the earlier of (i) May 22, 2025 and (ii) the occurrence of another Event of Termination, and as previously disclosed in the Current Report on Form 8-K filed on May 22, 2025, the Company and the other parties to the Forbearance Agreement further extended the Forbearance Period until the earlier of (i) May 29, 2025 and (ii) the occurrence of another Event of Termination. The Amendment further extends the Forbearance Period until the earlier of (i) June 2, 2025 and (ii) the occurrence of another Event of Termination.
