Standard Nuclear has sharply scaled back its planned initial public offering on the U.S. stock market, cutting the size of the deal by more than half — a move that reflects the cautious mood among investors this year.
The Oak Ridge, Tennessee-based company, which focuses on processing enriched uranium feedstock into advanced nuclear fuel for reactors including small modular reactors and microreactors, now plans to sell 10 million shares at $15 each. That’s a significant pullback from its original plan to offer 18.25 million shares priced between $18 and $21 apiece.
At the revised price of $15 per share, Standard Nuclear would be valued at approximately $2.4 billion — well below the $3.55 billion valuation it had previously targeted.
While the U.S. IPO market has generally bounced back in 2025, analysts note that investors remain selective, particularly when it comes to companies with higher risk profiles or less proven business models. Standard Nuclear is not alone in trimming its ambitions — ambulance company GMR and small modular reactor developer Deep Fission have also reduced the size of their IPOs in recent months.
IPOX CEO Josef Schuster pointed to the broader environment as a key factor. “The poor performance of recent IPOs, including SpaceX, is negatively affecting the demand for U.S. IPOs, in particular for high-risk, loss-making deals such as Standard Nuclear,” he said.
The company’s financials reflect its early-stage status. In the three months ending March 31, Standard Nuclear reported a net loss of $7.7 million on revenue of $593,802. That compares to a net loss of $8.3 million and revenue of $377,926 during the same period a year earlier. The company earns most of its revenue through fuel development agreements and research and development projects.
Schuster also noted that weakness within the nuclear sector itself is adding to the pricing difficulties. “Sector-specific weakness is contributing to the more challenging pricing environment,” he said, pointing to NuScale Power and Oklo, both of which have seen their stock values fall more than 35% so far this year.
Standard Nuclear was expected to finalize its IPO pricing on Wednesday, with its shares set to begin trading on the New York Stock Exchange on Thursday.
