Company context
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.
