This low-volume, high-visibility demonstration validates the technology in a real-world application, with field testing as the next step.

Financial Performance and Liquidity Strength

As a development-stage company, QuantumScape has not yet generated revenue from its principal business activities as of September 30, 2025. The company reported a GAAP net loss attributable to common shareholders of $105.8 million for the third quarter of 2025, narrowing from $119.7 million in the same period last year. The adjusted EBITDA loss for Q3 2025 was $61.4 million, aligning with expectations. For the nine months ended September 30, 2025, the net loss was approximately $334.9 million, contributing to an accumulated deficit of approximately $3.7 billion since inception.

Operating expenses for Q3 2025 totaled $115 million, a decrease from $130.2 million in Q3 2024. This reduction was primarily driven by a $6.8 million decrease in non-cash stock-based compensation, a $5.1 million decrease in personnel costs, and a $2.2 million decrease in materials costs within research and development (R&D). However, these were partially offset by a $9.2 million increase related to the write-off of fixed assets no longer in use, including leasehold improvements. General and administrative (G&A) expenses also saw a decrease, mainly due to lower non-cash stock-based compensation and reduced charges related to legal matters.

A notable financial development in Q3 2025 was the introduction of "customer billings" as a new operational metric, totaling $12.8 million. These represent the total value of invoices issued to customers and partners, signaling initial commercial traction and evidence of the capital-light business model at work. While these billings are expected to translate into future cash inflows, they are not a substitute for GAAP revenue and, for the PowerCo deal, will initially be recorded as a liability due to the related-party relationship, eventually accruing directly to shareholders' equity without a repayment obligation.

QuantumScape maintains a robust liquidity position, ending Q3 2025 with $1 billion in cash, cash equivalents, and marketable securities. The company bolstered its balance sheet by completing its at-the-market (ATM) equity program in Q3 2025, raising approximately $264.2 million in net proceeds.
