Deep Fission pushes back on short-seller claims, considers legal action

Deep Fission said a short-seller report targeting the company is misleading and contains inaccuracies. The nuclear technology developer noted the report's disclaimer describes its contents as opinions and says the author may hold short positions. Deep Fission said it is reviewing the report with advisors and evaluating possible legal remedies while standing by its public disclosures.
Deep Fission, a Nasdaq-listed nuclear developer in Parsons, Kansas, responded after a short-seller report criticized it and its technology. The company called the report misleading, citing distortions, inaccuracies and mischaracterizations. It noted the report’s disclaimer labels its contents opinions, not facts, and says the anonymous author may hold short positions that could profit from a stock decline.
Deep Fission said it stands by its public disclosures and SEC filings. Its Gravity reactor design would place a small modular pressurized water reactor about one mile underground, pairing established pressurized water reactor technology with an underground deployment model. The company is advancing its first project in Parsons and was selected for a U.S. Department of Energy pilot program.
The dispute may affect investors in Deep Fission and other early-stage nuclear firms, as short-seller claims can amplify share-price swings and uncertainty. If legal action follows, it could draw attention to disclosure standards and the risks of anonymous reports. Local stakeholders in Parsons and potential utility or data-center customers could also watch whether the controversy slows project momentum or erodes confidence in the company’s reactor plans.
