Deep Fission, Inc. is registering 2,500,000 shares of common stock in an initial public offering, with an expected price between $16.00 and $18.00 per share.
The company is a pre-revenue nuclear technology developer pursuing Nasdaq listing under “FISN” and building a small modular “Gravity Reactor” installed about one mile underground in deep boreholes. Its design adapts proven pressurized water reactor technology, targets 8–15 MWe per reactor, and uses low-enriched uranium fuel. The business plan relies on a three-phase deployment and DOE Reactor Pilot Program participation, with ambitious cost and revenue targets per reactor.
Deep Fission recently restated prior financial statements due to material errors in SAFE valuation and stock-based compensation and has identified material weaknesses in internal control over financial reporting, though management believes the included financials are fairly presented.
