Factorial Energy Inc. has entered the public markets through the completion of its business combination with Cartesian Growth Corporation III, marking a new phase for the U.S.-based solid-state battery developer. The combined company is expected to trade on the Nasdaq Stock Market under the ticker symbols FAC for its common stock and FACWW for its warrants. The listing positions Factorial to move beyond validation and toward broader commercialization of its next-generation battery platforms.
Market Debut
The transaction gives Factorial an implied equity value of approximately $1.3 billion and brings in more than $100 million in gross proceeds. The company said the capital will support the commercialization of solid-state batteries across defense and aerospace, hyperscale data centers, and e-mobility applications. The public listing also gives Factorial a wider investor platform as it seeks to scale technologies that have already been tested in demanding real-world environments.
Commercialization Strategy
Factorial is entering the market with backing from major automotive and strategic investors, including Mercedes-Benz, Stellantis, Hyundai, Kia, and In-Q-Tel. Its commercialization approach is built around joint manufacturing partnerships rather than a fully self-owned production model, which the company says is intended to support faster and more scalable deployment. This strategy reflects a broader industry push to bring solid-state batteries from laboratory validation into practical applications where higher energy density, safety, and performance are increasingly important.
Technology Milestones
The company’s recent progress includes vehicle integrations, drone partnerships, and battery cell advancements that demonstrate its push into multiple high-growth sectors. Mercedes-Benz previously integrated Factorial’s FEST cells into a lightly modified EQS test vehicle that completed a 1,205-kilometer journey from Stuttgart, Germany, to Malmö, Sweden, on a single charge. Factorial has also announced collaborations with drone integrators across several regions, as well as technology milestones connected to Stellantis testing and its earlier launch of a 100Ah-plus lithium-metal solid-state battery.
Leadership and Public Launch
Factorial’s leadership and board include executives with deep experience in batteries, automotive manufacturing, and large-scale industrial commercialization. The company highlighted figures such as Executive Chairman Joe Taylor, former chairman and CEO of Panasonic North America, and Dieter Zetsche, former chairman of Daimler and head of Mercedes-Benz Cars. To mark the transaction, Factorial is scheduled to ring the Nasdaq Opening Bell on June 17, 2026, with battery cells and demonstration vehicles displayed outside Nasdaq later that morning.
Factorial’s Nasdaq debut comes at a time when solid-state batteries are drawing strong interest from automakers, defense customers, aerospace companies, and energy infrastructure operators. By raising new capital and gaining public-market visibility, the company aims to accelerate the transition from proven prototypes and test programs to broader commercial deployment. The listing does not eliminate the manufacturing and adoption challenges facing solid-state technology, but it gives Factorial additional resources and visibility as it attempts to scale one of the battery industry’s most closely watched technologies.
