Nano

Nuclear Energy Inc. (the “Company,” “us,” “our,” or similar terminology), a Nevada corporation, has recently

submitted a private proposal to Dioxitek S.A., an Argentinian state-owned nuclear fuel cycle and uranium dioxide production company and

the country’s only feedstock manufacturer for nuclear fuel fabrication (“Dioxitek”), relating to the potential joint

development by the parties of a natural uranium hexafluoride (UF6) production facility on Dioxitek’s existing infrastructure in

Argentina.

This

development arises from a previously announced Memorandum of Understanding between the Company and Dioxitek, executed in August 2025,

which established a non-binding framework to assess the current capacities of natural uranium conversion and supporting infrastructure

in Argentina. The submission of the proposal by the Company reflects the outcome of this collaborative work, and the preparation and

submission of the proposal represents the Company’s next step towards the potential development of a UF₆ production capacity.

the Company’s proposal is reviewed as required by Argentinian law, further work is expected to be undertaken in coordination with

relevant stakeholders in Argentina to advance the assessment of technical, financial, and implementation considerations associated with

any potential facility development, all with a view towards the potential negotiation and execution of definitive documentation between

the Company and Dioxitek related to this project.

Cautionary

Note Regarding Forward Looking Statements

This

Current Report on Form 8-K (“Report”) contains or may contain “forward-looking statements” within the

meaning of Section 21E of the Securities Exchange Act of 1934, as amended, and the Private Securities Litigation Reform Act of 1995.

In this context, forward-looking statements mean statements related to future events, which may impact our expected future business and

financial performance, and often contain words such as “expects”, “anticipates”, “intends”, “explore”,

“aims,” “estimates”, “plans”, “believes”, “potential”, “eventual,”

“goal,” “will”, “should”, “could”, “would” or “may” and other

words of similar meaning. In this Report, forward-looking statements include those related to the potential future joint development

of a UF6 facility by the Company and Dioxitek as described herein. These and other forward-looking statements are based on information

available to us as of the date of this Report and represent management’s current views and assumptions. Forward-looking

statements are not guarantees of future performance, events or results and involve significant known and unknown risks, uncertainties

and other factors, which may be beyond our control. In addition, for the Company, particular risks and uncertainties that could

cause our actual future results to differ materially from those expressed in our forward-looking statements include but are not limited

to the following: (i) risks related to our U.S. Department of Energy (“DOE”), U.S. Nuclear Regulatory Commission (“NRC”),

Canadian Nuclear Safety Commission (“CNSC”) or related state or other U.S. or non-U.S nuclear licensing submissions, including

the risk that the Company’s proposal to Dioxitek may not be accepted or lead to definitive documentation, (ii) risks related to

the development of new or advanced technology and the acquisition of complementary technology or businesses, including difficulties with

design and testing, cost overruns, regulatory delays, integration issues and the development of competitive technology, (iii) our ability

to obtain contracts and funding to be able to continue operations, (iv) risks related to uncertainty regarding our ability to technologically

develop and commercially deploy a competitive advanced nuclear reactor or other technology within the timelines we anticipate,

if ever, (v) risks related to the impact of U.S. and non-U.S. government regulation, policies and licensing requirements, including by

the DOE, and the NRC, including those associated with the recently enacted ADVANCE Act and the May 23, 2025 Executive Orders seeking

to streamline nuclear regulation, and (vi) similar risks and uncertainties associated with the operating a developing business a highly

regulated, competitive and rapidly evolving industry, including that our plans may change and we may use our cash on hand faster or in

different ways than anticipated as our business requires. Readers are cautioned not to place undue reliance on these forward-looking

statements, which apply only as of the date of this Report. These factors may not constitute all factors that could cause actual

results to differ from those discussed in any forward-looking statement, and the Company therefore encourages investors to review

other factors that may affect future results in its filings with the SEC, which are available for review at www.sec.gov and at

https://ir.nanonuclearenergy.com/financial-information/sec-filings. Accordingly, forward-looking statements should not be relied

upon as a predictor of actual results. We do not undertake to update our forward-looking statements to reflect events or circumstances

that may arise after the date of this Report.
