QuantumScape (NYSE: QS) saw its shares climb approximately 10% in after-hours trading on Wednesday, even as the company reported a net loss of $84.5 million for the third quarter. The rally was fueled by an announcement of a partnership with Germany's Muehlbauer Group to equip a 100-megawatt-hour production line targeting a 2028 start, aimed at serving artificial intelligence data centers and other high-value markets.
The stock closed regular trading at $3.98 before the news. The company's quarterly loss of 14 cents per share was narrower than the 17 cents analysts had expected, and customer billings reached $9.8 million, including initial invoices from its Honda partnership. However, these billings are not recognized as revenue under U.S. accounting rules and do not indicate profitability.
Investors Overlook Another Loss
QuantumScape reported an adjusted EBITDA loss of $60.7 million for the quarter. The company ended September with $819.8 million in liquidity, providing a financial cushion as it continues to develop its manufacturing processes. Despite the ongoing losses, the market's enthusiasm centered on the manufacturing plan rather than proven commercial-scale sales.
During the earnings call, Deutsche Bank analyst Winnie Dong questioned the ownership and financing of the proposed facility, asking "who owns it, who pays." CEO Siva Sivaram said equipment costs borne by QuantumScape are targeted below $100 million, with additional funding from customers, government, and partners being explored.
AI Data Centers: A New Opportunity
QuantumScape's technology was originally developed for electric vehicles, where battery range and charging speed are critical. AI data centers, however, require compact backup systems capable of delivering intense power bursts near expensive computing equipment. On October 8, the company introduced QS PowerBlock, an in-rack energy storage design claiming four times the power density and five times the runtime of a reference industry specification—though these figures come from prototype testing and modeled configurations, not commercial installations.
William Blair analyst Mark Shooter questioned how cells designed for vehicles were adapted for data-center demands. Sivaram argued that high-power operation and thermal stability make the technology suitable for data centers, where battery safety is paramount. The Muehlbauer deal proposes volume production for data centers, aerospace, and defense, but customer interest and lab performance must still translate into repeatable, economically viable manufacturing.
2028 Target Raises Questions
The new production line is not expected to operate until 2028, and its location and complete funding arrangements remain undisclosed. QuantumScape maintained its 2026 adjusted EBITDA loss forecast of $250 million to $275 million and capital expenditure guidance of $27 million to $37 million.
UBS analyst Gabriel Gonzales asked whether commercial agreements might arrive in 2027, before the facility starts production. Sivaram said management wants multiple customers signed beforehand, highlighting the execution gap between pilot output and meaningful sales. The company plans to disclose more about its next-generation batteries at a Kyoto symposium on November 11.
