Deep Fission Inc., a company focused on developing underground small modular nuclear reactors, has kicked off an investor roadshow tied to a planned public offering of common stock. The proposed deal comprises 6 million shares with an anticipated pricing range between $24.00 and $26.00 per share, according to a company statement.
The company has given its underwriters a 30-day option to purchase as many as an additional 900,000 shares at the initial public offering price, less underwriting discounts and commissions. Deep Fission has filed to list its common stock on the Nasdaq Global Market, proposing the ticker symbol "FISN."
Deep Fission disclosed that net proceeds from the transaction are intended to support general working capital and corporate purposes. The company specified several uses for the funds, including engineering, research and development, licensing and the construction of its first pilot nuclear reactor and related technologies.
On the underwriting side, William Blair, Stifel and Canaccord Genuity are named as joint lead book-running managers for the offering. Seaport Global Securities and Benchmark, a StoneX Company, are listed as additional bookrunners.
The company has submitted a registration statement to the Securities and Exchange Commission in connection with the planned offering. That registration statement has been filed but has not yet become effective, a step the company noted in its filing.
Deep Fission develops small modular pressurized water reactors designed for installation approximately one mile underground, the company said. Beyond the technical description, the filing focuses on the mechanics of the proposed equity raise, the intended allocation of proceeds and the underwriting arrangements that would govern the offering.
The roadshow commencement signals the company is advancing toward a public equity transaction, but the filing-specific disclosures underscore that certain regulatory and administrative steps remain. The statement does not assert that the registration is effective, nor does it provide timing for listing or closing. The underwriters' 30-day option also means the total number of shares sold could increase if the option is exercised during that period.
