Key Takeaways:

Standard Nuclear, the only independent US manufacturer of TRISO nuclear fuel, is targeting a valuation of up to $3.55 billion in its initial public offering, the company said Tuesday.
"We are the only independent manufacturer of TRISO fuel in the United States, serving advanced nuclear reactors for terrestrial, national security and space applications," the company said in its registration statement filed with the Securities and Exchange Commission.
The Tennessee-based company plans to raise as much as $383.25 million by offering 18.25 million shares at $18 to $21 each. Underwriters have a 30-day option to purchase an additional 2.74 million shares. BofA Securities and Goldman Sachs are acting as joint lead bookrunners, with Barclays, UBS Investment Bank, Evercore ISI, RBC Capital Markets, William Blair and Stifel serving as additional bookrunners.
The listing comes as the IPO market regains momentum after a prolonged drought, with easing geopolitical tensions and resilient equity markets encouraging companies to proceed with listing plans. For Standard Nuclear, the offering taps into growing investor appetite for nuclear energy as a clean-power source capable of meeting surging electricity demand from artificial intelligence data centers and manufacturing reshoring.
Standard Nuclear produces TRISO — tri-structural isotropic — fuel, a particle-based technology designed to withstand extreme temperatures without melting, making it suitable for next-generation reactor designs. The company focuses on scaling domestic manufacturing capacity to reduce reliance on foreign suppliers for nuclear fuel, a priority for U.S. energy security policymakers who have allocated billions through the Inflation Reduction Act and the bipartisan infrastructure law to support advanced nuclear development.
The nuclear sector has drawn increased investor attention as utilities and technology companies seek carbon-free baseload power to support AI infrastructure expansion. Major technology firms have signed power purchase agreements with nuclear operators, and several advanced reactor developers including NuScale Power and Oklo have pursued public listings to fund their projects. Standard Nuclear's fuel production positions it as a supplier to multiple reactor developers rather than a single project developer, diversifying its revenue base across the emerging advanced nuclear ecosystem.
The company's listing on the New York Stock Exchange under the ticker STDN remains subject to the SEC declaring its registration statement effective. The company did not disclose a specific pricing date.
