Dismissal of Federal Securities Class Action Lawsuit Follows Dismissal of Related Shareholder Derivative Lawsuit

New York, NY, Jan. 09, 2026 (GLOBE NEWSWIRE) -- NANO Nuclear Energy Inc. (NASDAQ: NNE) (“NANO Nuclear” or “the Company”) , a leading advanced nuclear micro modular reactor (MMR) and technology company focused on developing clean energy solutions, announced today that the United States District Court for the Southern District of New York granted NANO Nuclear’s motion to dismiss the putative securities class action lawsuit filed against Nano Nuclear and certain of its officers and directors. The lawsuit, captioned Hongui Xie v. Nano Nuclear Energy, et al. , 1:24-CV-6057-JMF, made sprawling claims challenging statements about the qualifications of NANO Nuclear’s team and NANO Nuclear’s prospects for microreactor development, among others. In its Order dated January 8, 2026, the Court dismissed all claims against all defendants. The dismissal of this lawsuit follows the dismissal of a related shareholder derivative lawsuit NANO Nuclear announced in April 2025.

NANO Nuclear Energy Inc. (NASDAQ: NNE) is a North American advanced technology-driven nuclear energy company seeking to become a commercially focused, diversified, and vertically integrated company across five business lines: (i) cutting edge portable and other microreactor technologies, (ii) nuclear fuel fabrication, (iii) nuclear fuel transportation, (iv) nuclear applications for space and (v) nuclear industry consulting services. NANO Nuclear believes it is the first portable nuclear microreactor company to be listed publicly in the U.S.

Led by a world-class nuclear engineering team, NANO Nuclear’s reactor products in development include patented KRONOS MMR ™ Energy System , a stationary high-temperature gas-cooled reactor that is in construction permit pre-application engagement U.S. Nuclear Regulatory Commission (NRC) in collaboration with University of Illinois Urbana-Champaign, “ZEUS” , a portable solid core battery reactor, and the space focused, portable LOKI MMR ™ , each representing advanced developments in clean energy solutions that are portable, on-demand capable, advanced nuclear microreactors.

Advanced Fuel Transportation Inc. (AFT) , a NANO Nuclear subsidiary, is led by former executives from the largest transportation company in the world aiming to build a North American transportation company that will provide commercial quantities of HALEU fuel to small modular reactors, microreactor companies, national laboratories, military, and DOE programs. Through NANO Nuclear, AFT is the exclusive licensee of a patented high-capacity HALEU fuel transportation basket developed by three major U.S. national nuclear laboratories and funded by the Department of Energy. Assuming development and commercialization, AFT is expected to form part of the only vertically integrated nuclear fuel business of its kind in North America.

HALEU Energy Fuel Inc. (HEF) , a NANO Nuclear subsidiary, is focusing on the future development of a domestic source for a High-Assay, Low-Enriched Uranium (HALEU) fuel fabrication pipeline for NANO Nuclear’s own microreactors as well as the broader advanced nuclear reactor industry.

NANO Nuclear Space Inc. (NNS) , a NANO Nuclear subsidiary, is exploring the potential commercial applications of NANO Nuclear’s developing micronuclear reactor technology in space. NNS is focusing on applications such as the LOKI MMR ™ system and other power systems for extraterrestrial projects and human sustaining environments, and potentially propulsion technology for long haul space missions. NNS’ initial focus will be on cis-lunar applications, referring to uses in the space region extending from Earth to the area surrounding the Moon's surface.
