Standard Nuclear’s first day on the New York Stock Exchange ended with its shares down about 10% after the company significantly reduced the size of its initial public offering. The Oak Ridge, Tennessee-based firm, which converts enriched uranium feedstock into advanced fuel for reactors including small modular reactors and microreactors, opened at $13.50 a share, below its $15 offering price and reflecting a market valuation of $2.17 billion.
The muted reception comes even as interest in nuclear energy has resurged. The sector has drawn attention because of growing electricity needs tied to large-scale computing operations and regulatory moves that aim to accelerate deployment and strengthen supply chains. Technology companies and utilities seeking steady, carbon-free electricity have been cited as drivers of renewed demand for nuclear solutions.
Standard Nuclear’s chief executive, Kurt Terrani, said the company faces stronger demand than its current production can meet and positioned the capital raise as a way to expand manufacturing capacity. "We have more demand than we have production capability. The capital that we already had on our balance sheet and this new capital, positions us to expand our production capability," he said in an interview.
Despite the sector tailwinds, investors remain cautious about valuations and the risks associated with early-stage businesses in the nuclear supply chain. The company’s public market debut followed those of reactor developers X-energy and Deep Fission, which are also trading below their respective IPO prices, highlighting a broader pattern of investor selectivity within the field.
Policy developments are a prominent element in the current narrative for nuclear companies. Executive orders issued in May 2025 by the Trump administration are intended to speed up reactor approvals and support the nuclear fuel supply chain, a set of measures that industry participants expect will benefit firms involved in advanced reactor technologies and fuel production. President Trump has set an objective to expand U.S. nuclear power capacity substantially by 2050 to address anticipated electricity demand from data centers, electric vehicles and cryptocurrency operations.
Terrani also pointed to international opportunities and the administration’s policy actions. "This administration has been incredibly effective in policy. Beyond the United States, we see there’s huge opportunities for nuclear, where you need reliable, clean, low-cost energy," he said. On the interest from large-scale cloud providers and data center operators, he added that hyperscalers are "very interested in advanced nuclear" because it can offer economic and reliability benefits.
Standard Nuclear’s opening share price and the reduction in its offering size underscore the tension between growing commercial demand for advanced nuclear fuel and investor scrutiny of valuation and execution risk. The company’s role in processing enriched uranium feedstock into fuel for advanced reactors places it at the center of discussions about scaling production to meet anticipated market needs.
