QuantumScape Chief Technology Officer Timothy Holme sold 120,000 shares of Class A Common Stock on September 15, 2026. The transaction was executed under a Rule 10b5-1 trading plan established in June.
Why it matters
The sale highlights executive liquidity activity at the San Jose-based developer as the firm navigates a period of significant financial losses. QuantumScape reported a net loss of $98.2 million for the second quarter of 2026.
The transaction involved 120,000 Class A shares sold at an average price of $5.09, leaving Holme with 1,583,075 direct shares and 2.5 million derivative securities. The stock has faced downward pressure, recording a -51% return over the prior year and approaching its 52-week low of $4.77.
The players
QuantumScape Corporation
A San Jose-based developer of solid-state battery technology focused on energy density and charging performance for electric vehicles.
Timothy Holme
The co-founder and Chief Technology Officer at QuantumScape who leads the technical development of the company's proprietary ceramic separator technology.
The details
The sale was executed through a Rule 10b5-1 trading plan, a mechanism that allows corporate insiders to schedule pre-planned stock trades to avoid accusations of insider trading based on material non-public information. Holme established this specific plan on June 10, 2026, to systematically divest his remaining Class A holdings. While this position was liquidated, the CTO retains a significant stake through his direct shares and indirect holdings of Class B Common Stock.
Timeline
June 10, 2026: The Rule 10b5-1 trading plan was established.
Q2 2026: QuantumScape recorded a net loss of $98.2 million.
September 15, 2026: Timothy Holme sold 120,000 shares of stock.
The Tech Race
This divestment follows the standard pattern established by SEC Rule 10b5-1 to decouple executive stock sales from short-term market volatility or non-public information. The activity occurs as QuantumScape competes to commercialize its solid-state battery platform against established lithium-ion manufacturing leaders.
This transaction does not alter the company's product roadmap or the immediate availability of its battery prototypes. Investors should monitor future SEC filings for updates on executive holdings and the company's ongoing cash burn rate.
The takeaway
The move demonstrates a complete liquidation of the CTO's Class A share holdings while maintaining his long-term stake through Class B securities. Watch for the next quarterly financial report to see how the company manages its current $98.2 million net loss trajectory.
