Vancouver, British Columbia--(Newsfile Corp. - August 18, 2025) - GoviEx Uranium Inc. (TSXV: GXU) (OTCQB: GVXXF) ("GoviEx" or the "Company") is pleased to announce that it has today, 18 August 2025, entered into an arrangement agreement (the "Arrangement Agreement") with Tombador Iron Limited (ASX: TI1) ("Tombador") to complete a reverse takeover that will see GoviEx shareholders become the majority shareholders of an Australian listed company to be renamed Atomic Eagle Ltd ("Atomic Eagle" or the "Combined Company"). Tombador is a listed shell on the Australian Securities Exchange ("ASX"), having sold its operating iron ore business, and retained its ASX listing and approximately A$10.4 million² in cash reserves.

Pursuant to the Arrangement Agreement, Tombador will acquire 100% of the issued and outstanding Class A common shares of GoviEx (each, a "GoviEx Share") by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia) (the "Arrangement" or the "Transaction"). On closing of the Transaction, GoviEx shareholders will own 75%¹ of the Combined Company while Tombador's existing shareholders will hold 25%¹ of the Combined Company. Additionally, Tombador will undertake a concurrent financing of at least A$5.0 million and up to A$10.0 million bringing the Combined Company's cash balances to between A$19.4 million and A$24.4 million.

Commenting on the Transaction, Govind Friedland, GoviEx's Executive Chairman said: "This is a transformational transaction for GoviEx: it brings an Australian public listing, a new capital structure, a refreshed board, new substantial shareholders, a cornerstone investor with recent uranium development experience and a strengthened balance sheet. Our Combined Company, to be named Atomic Eagle Ltd, will lead the development of the Muntanga Project, situated in one of the largest and most under explored sandstone hosted uranium basins in the world, with considerable exploration potential. We are excited to move forward with unlocking its full potential."

Tombador's Executive Director, Stephen Quantrill, said: "Uranium is growing in importance and prominence in the global transition to clean energy. Tombador acknowledges the pedigree and long history of the GoviEx team and assets, and we welcome the opportunity to work with Govind Friedland and his team alongside the experienced leadership from Matador Capital to realise the potential of the GoviEx projects.

"This transaction brings together the proven track record and pedigree of the GoviEx team with the leadership and operational experience of Matador. We see enormous potential in Muntanga and look forward to continuing its development."

The Transaction is expected to offer significative benefits to GoviEx and its shareholders:

• Improved valuation environment with deep capital pool access. An ASX listing for the Combined Company is expected to provide access to deep pools of capital for African uranium explorers and developers with potential for significant valuation uplift upon delivery of key milestones.

• Efficient, low-cost transaction. The Arrangement will provide GoviEx shareholders with an efficient, low-cost transaction structure via reverse takeover, ensuring the Company has a robust capital structure on listing.

• Strong cash balance. As a result of the Arrangement, the Combined Company is expected to be well capitalized with a pro forma cash balance between A$19.4 million and A$24.4 million upon completion, assisting the Combined Company to avoid short term debt. The Combined Company anticipates deploying these funds as well as other funds it raises to further the development of its Muntanga uranium project in Zambia (the "Muntanga Project").

• GoviEx to own majority. The Arrangement will result in GoviEx shareholders owning approximately 75%³ of the Combined Company.

• Tighter capital structure. The Combined Company will have a significantly reduced share count, from 1,022,062,190 GoviEx Ordinary Shares currently issued and outstanding to 345,315,243 on completion of the Arrangement³. This is expected to result in a more efficient float, and reduced share price volatility. This structure also provides greater flexibility for future capital raises.

• The addition of Matador Capital Pty Ltd. ("Matador"). In addition to the ASX listing and a minimum A$5.0 million (and up to A$10.0 million) capital raising to be completed concurrently with the closing of the Transaction (the "Capital Raising"), the Arrangement brings in the key personnel of Matador to support the Combined Company. Grant Davey, founder of Matador Capital, will be appointed as strategic advisor to the board. Matador has a track record of working with and developing mining and energy projects including uranium mining companies and their projects on the ASX, such as Lotus Resources and Boss Energy.

• Team strategically aligned for the next stage of growth. Daniel Major (GoviEx's CEO) will retain his position and be the CEO of the Combined Company. A new board with seasoned industry professionals will be chaired by Govind Friedland (currently Executive Chairman of GoviEx). Eric Krafft (GoviEx), Stephen Quantrill (Tombador) and Keith Bowes (ex-MD Lotus Resources) will be appointed as non-executive directors.

• Corporate rebranding and reset. The Arrangement includes a rebranding that better reflects the Company's strategic focus, market opportunity and position in the market of uranium exploration companies.

• Continued focus on Zambia and the Muntanga Project. The Transaction is expected to enable the Combined Company to position its development strategy towards continuing to significantly increase the size of Muntanga Project and achieving economies of scale to improve the potential project economics and benefits for all stakeholders, as well as targeting the substantial exploration potential of the Karoo sandstones in Zambia.

• The transaction includes GoviEx Niger with no impact on ongoing proceedings.
