Radnostix Signs Definitive Agreement to Divest DUF6 and Fluorine Assets to NANO Nuclear

BOISE, Idaho, Oct. 1, 2026 /PRNewswire/ -- Radnostix, Inc. (formerly International Isotopes Inc.) (OTCQB: INIS) ( "Radnostix" or the "Company") today announced that Radnostix and its wholly-owned subsidiary, International Isotopes Fluorine Products, Inc, have entered into a definitive asset purchase agreement with NANO Nuclear Energy Inc. (NASDAQ: NNE) and its wholly-owned subsidiary, HALEU Energy Fuel Inc., (collectively "NANO"), to divest its U.S. nuclear fuel processing assets, including a U.S. Nuclear Regulatory Commission ("NRC") license and related intellectual property and technical materials associated with depleted uranium hexafluoride ("DUF6") deconversion and fluorine extraction capabilities at a facility anticipated to be located in Lea County, New Mexico.

Transaction Terms and Next Steps

The proposed acquisition would provide NANO Nuclear with existing NRC 10 CFR Part 40 licensed fuel cycle assets and a substantial body of associated licensing and technical work. The NRC license was originally issued in connection with a proposed facility in Lea County, New Mexico designed to support DUF6 deconversion and fluorine extraction activities. The proposed acquisition also includes related patented technology, engineering and safety analyses, regulatory and permitting materials, equipment and historical project development records. The facility contemplated under the existing license was not previously constructed.

Under the asset purchase agreement, the consideration being paid for the assets at closing is $9.5 million in cash and $4.0 million in NANO common stock, payable and issuable at closing in accordance with the agreement.  Closing remains subject to NRC consent to the license transfer, other required approvals and consents (including from New Mexico officials), satisfactory site arrangements and other closing conditions. The parties currently expect closing in approximately 90 to 120 days, although the timing will depend on those approvals and conditions.

Radnostix Focus on Radioisotope Technologies

This transaction represents a major centering event for Radnostix, allowing the Company to focus on its core radioisotope technology segments while significantly strengthening its balance sheet for the next chapter of the business. Following closing, Radnostix intends to utilize the net proceeds to accelerate the growth of its four radioisotope technology product segments through a combination of enhanced research and development and continued organic and inorganic growth initiatives.

"We have complete confidence in NANO to take these DUF6 deconversion and fluorine extraction assets across the finish line and fill a material need for the U.S. Nuclear Fuel Cycle industry," said Shahe Bagerdjian, Chief Executive Officer of Radnostix. "The site, license, and technology sit squarely inside NANO's strategy to become a vertically integrated nuclear energy company, and we are excited to become NANO shareholders." Mr. Bagerdjian added, "For Radnostix, this transaction gives us the best of both worlds, allowing us to retain some upside via NNE stock while we can fully focus on our radioisotope technologies in medical and industrial applications.  We have a number of initiatives in our R&D & growth pipeline that upon closing Radnostix will be able to accelerate the development of.  While we have completed a few modest acquisitions over the past couple of years, the proceeds from the transaction will allow us to broaden our horizons, and fuel our growth rate."
