Solid Power, Inc. (Nasdaq: SLDP) reported a board change effective July 1, 2026, appointing Uwe Breitweg as a Class III director. The appointment was made by the company’s Board of Directors and disclosed under Form 8-K Item 5.02, which covers director and officer changes and related compensatory arrangements. Breitweg was nominated by BMW Holding B.V. under BMW Holding’s director nomination rights in a Board Nomination and Support Agreement dated May 5, 2021, among Solid Power, BMW Holding and certain stockholders. He succeeds Rainer Feurer as BMW Holding’s nominee on Solid Power’s board, following Dr. Feurer’s previously reported retirement from the board. Breitweg’s term is scheduled to run until Solid Power’s 2027 annual meeting of stockholders and until a successor is duly elected and qualified. Solid Power noted that, because of the company’s commercial relationship with Bayerische Motoren Werke AG and BMW-related affiliates, including BMW of North America, LLC and BMW Holding, the board determined that Breitweg is not independent under Nasdaq rules. As a result, he is not expected to serve on any board committees. The filing also states that Breitweg agreed to waive all compensation payable by Solid Power for his board service. In connection with the appointment, Solid Power and Breitweg entered into the company’s standard indemnification agreement, which provides customary protections for directors. The company also furnished a July 1, 2026 press release announcing the appointment under Item 7.01 Regulation FD Disclosure, with the release included as Exhibit 99.1. No share issuance, insider stock transaction, option grant, transaction code, price, or change in beneficial ownership was reported in this filing.
