Advanced nuclear energy company Deep Fission (See Pulse 2.0 profile here) announced the launch of its proposed underwritten initial public offering of 6 million shares of common stock. The company also intends to grant underwriters a 30-day option to purchase up to an additional 900,000 shares at the initial public offering price, less underwriting discounts and commissions.
The expected IPO price range is between $24 and $26 per share, which would value the base offering at approximately $144 million to $156 million before any exercise of the underwriters’ option. Deep Fission has applied to list its shares on the Nasdaq Global Market under the ticker symbol “FISN.”
The company said proceeds from the offering will be used for general working capital and corporate purposes, including engineering, research and development, licensing, and construction activities related to its first pilot nuclear reactor and associated technologies.
Deep Fission is developing small modular pressurized water reactors designed to operate approximately one mile underground using its Gravity Nuclear Reactor™ deployment model. The company’s approach combines conventional pressurized water reactor technology with underground borehole deployment aimed at simplifying construction, improving safety, and enabling scalable commercial deployment.
The company is targeting growing electricity demand from utilities, industrial customers, and data centers with its low-carbon baseload power technology.
William Blair, Stifel, and Canaccord Genuity are serving as joint lead book-running managers for the offering. Seaport Global Securities and Benchmark, a StoneX company, are acting as bookrunners.
