Standard Nuclear, a Tennessee company that makes ceramic pellets filled with uranium, has the potential to be a central player in the new nuclear supply chain. The company completed its initial public offering on Wednesday, raising $150 million at $15 a share, at a valuation around $2 billion. It's expected to start trading Thursday around midday under the ticker STDN.
Standard Nuclear occupies a niche in the new nuclear universe: it takes uranium that was mined and enriched by other companies and packages it into poppyseed-sized pellets that it sells to reactor owners. The pellets are expected to work well in the small and microsize reactors being developed today for use at specialized sites, like at data centers. Dozens of companies are developing those reactors, and are expected to need much more fuel for them than is available in the market today.
"There's a lot more demand than we have capacity," said CEO Kurt Terrani in an interview with Barron's. "This IPO is gonna put us in a very, very good position. We had a really strong balance sheet before the IPO. Now we have even more resources."
Standard Nuclear has ramped up fast, after buying assets from a bankrupt nuclear company in 2024. It's already producing and selling nuclear fuel, and was chosen by the Department of Energy as a partner in the government's nuclear acceleration program. That said, Standard Nuclear has been losing money as it ramps up, posting a $7.7 million loss in the first quarter.
Its success will depend on the success of the broader nuclear ecosystem -- particularly the novel kinds of reactors being developed by companies like Oklo, privately held Radiant Industries and X-Energy, which is also making fuel pellets.
Lately, investors have soured on some of the new nuclear stocks, which may have also depressed interest in Standard Nuclear's offering. The company downsized the IPO from its initial expectations.
