Appointment of New Director

On November 6, 2025, Craig Cornelius was appointed to the Board of Directors (the “Board”) of Sunrun Inc. (the “Company”), effective November 6, 2025. Mr. Cornelius will serve as a Class III director and will stand for reelection at the 2026 annual meeting of stockholders. The Board also appointed Mr. Cornelius to serve on the Audit Committee and the Nominating, Governance, and Sustainability Committee of the Board. In connection with the appointment of Mr. Cornelius, the size of the Board was increased from eight to nine.

Mr. Cornelius has served as President and Chief Executive Officer of Clearway Energy Group LLC (“Clearway”) since September 2018 and as Chief Executive Officer of its public affiliate Clearway Energy, Inc. (“CWEN”), which is publicly traded on the NYSE under the symbols CWEN and NYSE:CWEN.A, since July 2024. His service as Chief Executive Officer of Clearway commenced on the company’s formation through a spin-out of NRG Energy, Inc.’s (“NRG”) clean energy businesses in 2018. Previously, Mr. Cornelius was President of NRG’s renewables division. In this capacity, he oversaw origination, development, engineering and construction, operations and asset management across the company’s businesses in wind and solar power. He joined NRG in 2013 and initially led new business development for renewables, including the establishment of new market segments, project acquisitions, and process improvement initiatives. Before joining NRG, Mr. Cornelius served for five years as a Principal and then a Managing Director in the solar investing practice at Hudson Clean Energy Partners. Previously, he was the Program Manager of the U.S. Department of Energy’s Solar Energy Technologies Program, where he led the creation of the $1.5 billion Solar America Initiative.

Mr. Cornelius holds an A.B. from Princeton University in History of Science and an M.A. in Science, Technology, and Public Policy from George Washington University.

Mr. Cornelius was selected to serve on the Board because of his extensive operational and financial experience and deep knowledge of the energy industry.

There is no arrangement or understanding between Mr. Cornelius and any other person pursuant to which he was selected as a director, and there is no family relationship between Mr. Cornelius and any of the Company’s other directors or executive officers. There are no transactions between Mr. Cornelius and the Company that would be required to be reported under Item 404(a) of Regulation S-K.

As a non-employee director of the Company, Mr. Cornelius is eligible to receive compensation pursuant to the Company’s Non-Employee Director Compensation Policy, a copy of which was filed as Exhibit 10.21 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024.
