Rhea-AI Summary

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.
