QuantumScape Corporation (NASDAQ: QS) shares surged 16.52% on June 18, closing at $8.04, following the announcement of a major joint research agreement with Honda R&D Co., Ltd.
The agreement between QuantumScape and Honda R&D, a subsidiary of Honda Motor Co., Ltd. (NYSE: HMC), is aimed at advancing the QS solid-state battery platform through the combined expertise of both companies.
The multi-year joint program will focus on solid-state battery development as well as the associated manufacturing processes required to bring the technology to commercial scale.
The deal follows Honda’s successful completion of a prior technology evaluation agreement with QuantumScape, which included hands-on technical study and competitive benchmarking across a range of standard technical tests.
QuantumScape CEO and President Dr. Siva Sivaram described the partnership as a significant endorsement of the company’s technology platform and its potential across multiple applications.
“Honda is a leading global automaker renowned for its engineering excellence and product quality across automotive and other applications worldwide, and its evaluation represents one of the most rigorous assessments of our technology to date,” Dr. Sivaram said.
He added that “this agreement reflects the growing confidence in QS solid-state lithium-metal batteries to enable safer, higher-density energy storage,” signaling broader ambitions beyond the EV market.
Honda represents QuantumScape’s second major original equipment manufacturer partnership, following an earlier relationship with Volkswagen, reinforcing the company’s growing credibility among global automakers.
Trading volume on June 18 reached 79.0 million shares, approximately 271% above the stock’s three-month average of 21.3 million shares, reflecting strong investor enthusiasm around the announcement.
Investors are also turning attention to QuantumScape’s late-July earnings window, as the market looks for updates on the company’s commercialization strategy and financial trajectory.
QuantumScape, which went public in 2020, has declined approximately 19% since its IPO, though today’s session marked one of the more significant single-day rallies in the stock’s recent history.
The broader market also finished higher on June 18, with the S&P 500 closing up 1.08% at 7,501 and the Nasdaq Composite rising 1.91% to close at 26,518.
