NANO Nuclear Energy Closes $105 Million Common Stock Private Placement

NANO Nuclear’s cash position at over $210 Million, which will fuel the company’s continued innovations in the advanced nuclear energy sector 

Financing included primary participation from fundamental institutional investors, including a pre-eminent global investment manager and a leading long-only mutual fund

New York, N.Y., May 29, 2025 (GLOBE NEWSWIRE) -- NANO Nuclear Energy Inc. (NASDAQ: NNE) (“NANO Nuclear” or “the Company”), a leading advanced nuclear energy and technology company, today announced the closing of its previously announced common stock private placement for gross proceeds of approximately $105 million, before deducting offering expenses. Net proceeds to NANO Nuclear are expected to be approximately $99 million.

Primary participation in the private placement came from fundamental institutional investors, including a pre-eminent global investment manager and a leading long-only mutual fund. In the private placement, NANO Nuclear sold 3,888,889 shares of common stock at a purchase price of $27.00 per share.

The proceeds from this financing significantly boosts NANO Nuclear’s cash on hand to over $210 million. With these resources, NANO Nuclear will be able to more readily advance its cutting-edge micro nuclear reactors and auxiliary nuclear energy-related businesses, as well as seek complimentary acquisitions and drive growth towards initial revenue generation.

“We are very grateful to have secured this new capital, our largest funding round yet, which was also completed at our highest financing valuation to date and puts our cash on hand at over $210 million,” said Jay Yu, Founder and Chairman of NANO Nuclear Energy. “This achievement was made possible through the participation of well known, long term fundamental institutional investors who understand not only the nuclear energy renaissance we are participating in, but the specific potential for NANO Nuclear’s technologies and business plans. We expect this capital will accelerate our near- and longer-term valuation catalysts, particularly given the high technology readiness level of our KRONOS MMR^™ microreactor (being developed in conjunction with University of Illinois Urbana-Champaign) and our planned commencement of geological site characterization activities, including subsurface drilling investigations, for this reactor, which would be first research microreactor built on campus grounds in the U.S by an advanced reactor company. These activities will lead to the submission of our KRONOS MMR construction permit applications to the Nuclear Regulatory Commission thereafter. We also applaud last week’s presidential executive orders aimed at boosting nuclear energy in the U.S. and streamlining nuclear regulation, which will drive tailwinds for us and the entire nuclear energy sector in coming years. Our mission to become a leading, diversified, and vertically integrated advanced nuclear energy company has taken another large step forward, and we look forward to deploying our capital to drive innovation in our industry and value for our stockholders.”

Titan Partners Group, a division of American Capital Partners, acted as the sole placement agent for the offering. Ellenoff Grossman & Schole LLP acted as counsel to NANO Nuclear, and Lucosky Brookman LLP acted as counsel to the placement agent.

About NANO Nuclear Energy, Inc.

NANO Nuclear Energy Inc. (NASDAQ: NNE) is an 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 (U. of I.), “ZEUS”, a solid core battery reactor, and “ODIN”, a low-pressure coolant 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.
