Sunnova Announces Strategic Action to Facilitate Value-Maximizing Sale Process

Files voluntary petitions for chapter 11 with support of key financial stakeholders

Continues to service and manage customers' solar and storage systems in the ordinary course of business at this time

Receives interim Court approval on "First Day Motions" to enable continued operations

Enters into Asset Purchase Agreement with ATLAS SP Partners and Solar Power System Purchase Agreement with Lennar Homes, LLC to secure new capital to support operations

Sunnova Energy International Inc. ("Sunnova" or the "Company") (NYSE:NOVA) today announced that on June 8, 2025, the Company and certain of its subsidiaries voluntarily filed petitions for chapter 11 relief in the United States Bankruptcy Court for the Southern District of Texas ("the Court") to facilitate a sale process for certain of the Company's assets and business operations. The Company intends to continue operating its business in the ordinary course throughout the sale process.

In order to maximize value for all stakeholders, Sunnova will conduct a court-supervised sale process to elicit the highest or otherwise best bid for the Company's assets. Sunnova expects to complete the marketing and sale process, which will provide interested parties the opportunity to submit competing bids for the Company's assets, in approximately 45 days.

"Today's actions mark a critical step towards securing a value-maximizing outcome for Sunnova's stakeholders," said Paul Mathews, Chief Executive Officer of Sunnova. "Throughout this process, maintaining continuity of service for our customers is our top priority as we work to secure a long-term solution for our business operations under new ownership. I'm incredibly grateful to our dedicated Sunnova team for their hard work and commitment. We have built an innovative power provider, and I continue to believe deeply in the future of our industry and the promise of residential solar and storage."

Sunnova intends to continue to monitor, manage, and service solar and storage systems in the ordinary course during the sale process. The Company plans to communicate directly with customers regarding any material changes that may impact the service and support provided by Sunnova.

Entry into the Asset Purchase Agreement and Settlement Agreement with ATLAS SP Partners and Solar Power System Purchase Agreement with Lennar Homes, LLC

Sunnova announced that it has entered into an asset purchase agreement (the "Asset Purchase Agreement") between Sunnova Energy Corporation ("SEC"), Sunnova TEP Developer, LLC ("TEP Developer"), Sunnova TEP Holdings, LLC ("TEP Holdings"), and Sunnova TEP Holdings Subsidiary, LLC ("TEPH Subsidiary") under which certain solar systems, and rights and customer agreements related to them, will be sold to TEPH Subsidiary. The purchase price of $15.0 million will be paid from proceeds borrowed under TEP Holdings' existing warehouse credit facility. ATLAS SP Partners ("ATLAS"), Sunnova, and certain of its affiliates also entered into a settlement agreement (the "Settlement Agreement"). Upon approval of the Asset Purchase Agreement and Settlement Agreement by the Court, Sunnova will facilitate ATLAS' direct negotiations with certain dealers and installers that have worked with Sunnova in the past with the goal of completing certain in-process solar systems. The Asset Purchase Agreement and Settlement Agreement will provide Sunnova with additional liquidity to support its operations and the payment of employee obligations during the chapter 11 process.

The Company has also entered into an Asset Purchase Agreement (the "Solar Power System Purchase Agreement") with Lennar Homes, LLC. Upon Court approval, Lennar will acquire certain assets related to Sunnova's New Homes business unit for aggregate consideration of approximately $16.0 million.

Tax Equity Partnerships and Asset Backed Securities Remain Intact

The chapter 11 filing and the various transactions in connection with it will not have any material impact on Sunnova's closed tax equity partnership affiliates or asset-backed securities, as those investment structures are bankruptcy remote. The Company intends to continue to prioritize servicing and performance for the benefit of its asset-backed security holders and tax equity partners.

Operations During Chapter 11

Sunnova intends to use the funds from the Asset Purchase Agreement and Solar Power System Purchase Agreement, upon approval by the Court, as well as cash-on-hand, to support core business operations during the initial period of the chapter 11 sale process as the Company works to finalize ongoing initiatives to secure additional capital.

Among other customary relief, the Court granted interim approval on a number of customary "First Day Motions" to facilitate a smooth transition into chapter 11, including requests for approval to continue to pay employee wages and benefits, maintain customer programs and service, and honor post-petition obligations to its commercial partners, providing the Company the ability to continue certain business operations during the chapter 11 process.

The Company has also secured interim relief to continue to uphold and honor loan agreements, lease agreements, power purchase agreements, service agreements, managed solar renewable energy certificates and demand response agreements, warranties, and production guarantees throughout the chapter 11 process.

This filing follows the voluntary chapter 11 petition filed by TEP Developer, a subsidiary of the Company, on June 1, 2025. Sunnova has sought relief to jointly administer these chapter 11 cases.
