QuantumScape Corporation, through its wholly owned subsidiary QuantumScape Battery, Inc., entered into an amendment to its Amended and Restated Collaboration Agreement with PowerCo SE on July 16, 2026. PowerCo is a battery cell company wholly owned by the Volkswagen Group and a major investor in QuantumScape.
The amendment refocuses the joint program on automotive cell development, larger format cells, and the company’s future technology roadmap for QSE-5 Technology, including transfer into a cell size to be determined by PowerCo. It replaces the prior statement of work and cost-reimbursement structure with milestone-based payments tied to development, validation, demonstration and delivery of battery cells over the next two years. The maximum aggregate amount QuantumScape will receive from PowerCo for this program is $75.4 million, inclusive of amounts paid to date. Statement of Work No. 1 was terminated and replaced by the new terms, and invoiced obligations to date remain payable; the amendment does not change the potential IP License Agreement terms previously described.
