QuantumScape Beats Q3 Earnings Estimates

Customer billings reached $9.8 million, including the company's first billings under its Honda (HMC) agreement. It also recorded initial billings from its advanced solutions business, which serves defense and aerospace customers.

QuantumScape ended the quarter with $819.8 million in liquidity. It kept its 2026 adjusted EBITDA loss outlook at $250 million to $275 million. Full-year capital spending is expected to range from $27 million to $37 million.

QuantumScape Plans Battery Line for AI Data Centers

QuantumScape plans to build a 100-MWh battery production line with Germany's Muehlbauer Group, which will supply cell-assembly equipment. Production is targeted to start in 2028, with the line aimed at AI data centers and other advanced markets rather than carmakers.

The project builds on the company's Eagle Line pilot facility in San Jose, which is producing cells for customer samples. Equipment costs for the new line are expected to stay below $100 million. QuantumScape is seeking funding that would avoid issuing more shares.

The company is also targeting AI data centers with its QS PowerBlock energy storage system. The system uses its QSE-5 solid-state cells and is designed to fit inside data center racks.

By targeting AI data centers, QuantumScape aims to expand beyond EV batteries and tap into demand for energy storage in computing infrastructure.
