Analysis · FISN · Energy & Transportation
In its first quarterly filing as a public company, Deep Fission drops a going concern warning: management admits its $93 million cash balance won't last a year. The pre-revenue nuclear startup burned through $42.5 million in just six months, weighed down by heavy R&D and stock-based compensation. Material weaknesses in financial controls remain unremediated. With the recent IPO and private placement proceeds already earmarked, the company must raise substantial capital soon to survive. A conditional DOE approval for its reactor design offers a bright spot, but it does nothing to ease the immediate cash crisis.
At the time of this filing, FISN was trading at $10.11 on NASDAQ in the Energy & Transportation sector, with a market capitalization of approximately $598.5M.
