Factorial Lists on Nasdaq,
Bringing Solid-State Batteries From Validation to Scale
Leading American solid-state battery innovator, backed by global automakers and rapidly expanding into defense & aerospace, robotics, and hyperscale data centers, enters public markets with $1.3 billion equity value
Boston, MASS. – June 8, 2026 – Factorial Inc. (“Factorial”), a U.S. developer of solid‑state battery technology, announced today that it has completed its previously announced business combination with Cartesian Growth Corporation III, a publicly traded special purpose acquisition company. The combined company will operate as Factorial Energy Inc., and its Series A common stock and warrants are expected to begin trading on the Nasdaq Stock Market (“Nasdaq”) under the ticker symbols “FAC” and “FACWW”, respectively, on June 8, 2026.
The transaction implies an equity value of approximately $1.3 billion and provides more than $100 million in gross proceeds to support continued commercialization of Factorial’s next generation batteries for defense & aerospace, hyperscale data centers, and e-mobility.
Factorial enters the public markets with a track record few battery companies match – support from the U.S. national security investment community, real world vehicle integrations, expansion into high‑performance drones, and progress toward the first U.S. solid‑state production program for passenger vehicles. Factorial’s capital-light commercialization model, built on joint manufacturing partnerships, is designed for rapid, scalable deployment.
“We built Factorial to solve one of the hardest problems in energy – making solid‑state real at scale,” said Siyu Huang, CEO of Factorial. “The automotive industry is the most demanding proving ground in the world, and we’ve shown our technology can perform in real cars on real roads. That foundation positions us to scale, providing power to drones, robotics, and next generation energy systems. Listing on Nasdaq gives us the platform to accelerate that work and deliver solid‑state technology where it matters most.”
“The team at Factorial is dedicated not just to powering the next generation of drones, robots, e-mobility and energy storage, but to creating long-term shareholder value,” noted Peter Yu, Chairman & CEO of Cartesian Growth Corporation III. “We are proud to anchor the common-equity PIPE and even more excited to open Factorial’s cap table to investors seeking to participate in the company’s brilliant future.”
