(Incorporated in Delaware)

Our mission is to supply advanced nuclear fuels that enable safe, reliable and scalable nuclear power generation. We aim to support the re-emergence of the U.S. newbuild nuclear infrastructure, strengthen domestic energy security and meet the nation’s growing demand for safe, reliable and clean baseload power.

Company Overview

Standard Nuclear is a leading independent advanced nuclear fuel company and the only company in the United States with industrial-scale TRISO manufacturing facilities to date, based on our commercialized manufacturing capability supported by production-grade equipment, established processes, and facility infrastructure designed for sustained, high-throughput output and scalable expansion. We design, engineer, and manufacture advanced nuclear fuels with a primary focus on TRISO fuel that is utilized by advanced nuclear reactors, including some SMRs and microreactors, designed to be safer, more efficient, and more flexible than traditional nuclear reactors (“Advanced Reactors”), and we believe we are the only participant in the market that is currently positioned to be able to work with and develop fuel for any developer of Advanced Reactors which use TRISO fuel. As of the date of this prospectus, we operate the only dedicated, privately funded, industrial scale TRISO production line in the United States and are currently producing and shipping fuel for Advanced Reactor demonstrations scheduled for 2026, with additional TRISO production facilities expected to come online in the second half of 2026.

Led by internationally recognized nuclear fuel expert Dr. Kurt Terrani, who serves as our Chief Executive Officer, our technical team leverages over 150 years of combined U.S. National Laboratory experience in the development, fabrication, and testing of advanced fuels, and many of our technical team members have previously held critical leadership roles in the U.S. Department of Energy’s (the “DOE”) advanced gas reactor program, which established the modern TRISO fuel standard currently accepted by the NRC. We believe the qualifications exhibited by our elite technical team, together with our ownership and operation of facilities licensed for the large-scale manufacturing of TRISO-based fuels, makes us a leading nuclear fuel company capable of delivering advanced nuclear fuel to the growing industry.

Our company was built on the basis of certain nuclear-fuel related assets purchased at auction in late 2024 following the bankruptcy of the Ultra Safe Nuclear Corporation and we have a limited operating history upon which investors can evaluate our business and prospects. While we have commenced commercial operations, our business model and operating assumptions remain unproven at the industrial scale we are targeting, and we may not achieve the growth, yields, or profitability that we expect. As we transition from our initial development and commercial activities to regulated manufacturing of nuclear fuels at scale, we must continue to establish repeatable processes, qualify suppliers, and demonstrate compliance programs across our existing and planned facilities.
