NANO Nuclear Energy Announces Second Fiscal Quarter and Recent Operational Highlights and Provides Corporate Outlook 

New York, N.Y., May 16, 2025 (GLOBE NEWSWIRE) — NANO Nuclear Energy Inc. (NASDAQ: NNE) (“NANO Nuclear” or “the Company”), a leading advanced nuclear energy and technology company focused on developing clean energy solutions, today announced its second fiscal quarter ended March 31, 2025 and more recent operational highlights and provided an outlook on its expectations and goals for 2025 and beyond.

“We started 2025 with a view to build on a successful 2024, and have done just that, pursuing and executing on our objectives efficiently,” said Jay Yu, Founder, Chairman and President of NANO Nuclear. “The acquisition of the rebranded, high technology readiness level stationary KRONOS MMR^™ and portable LOKI MMR™ microreactors, which were finalized at the start of the year, has put us in a leading position in the microreactor race in U.S. We have solidified our relationship and working agreements with the University of Illinois Urbana-Champaign (UIUC) for the KRONOS MMR and are now working to construct the first research microreactor on campus grounds in the U.S. We are confident our efforts at UIUC will lead to eventual commercialization of many KRONOS MMRs being constructed throughout many industries across the world. The U.S. Nuclear Regulatory Commission (NRC) approved the Fuel Qualification Methodology Topical Report for the KRONOS MMR, which is a major milestone for the commercial microreactor sector in general and crucial for the eventual construction of the microreactor system on campus grounds. In the coming months, we expect to begin the process of geological characterization, including subsurface investigations, which will lead to our construction permit applications and other future project milestones.”

“In addition, NANO Nuclear has amassed dozens of domestic and international patents through our KRONOS and LOKI acquisition. We are also further expanding our current intellectual property protections with over a dozen new patent applications surrounding our microreactor portfolio, and supplementary technologies like our ALIP pump system,” continued Mr. Yu. “This year has also seen us commit to a new, multimillion dollar demonstration facility in Westchester County, New York, where the development of non-nuclear components, including commercializing the ALIP technology, will take place. Furthermore, our team has grown, and we have attracted many full-time engineers, regulatory and licensing experts, led by a world class Chief Technical Officer and Head of Reactor Development, Dr. Florent Heidet. This positive start to the year positions us well to achieve further milestones during the rest of 2025 and lays a solid foundation for achieving our longer term demonstration, regulatory licensing and commercialization goals.”
