Noble Plains Uranium Corp. (TSX-V: NOBL) (OTCQB: NBLXF) (FSE: INE0) a U.S.-focused uranium exploration and development company, is pleased to announce that it has entered into a binding letter of intent dated October 30, 2026 with Eagle Nuclear Energy Corp. (NASDAQ: NUCL), pursuant to which Eagle proposes to acquire all of the issued and outstanding common shares of the Company by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia). If the Proposed Transaction is completed, Noble Plains would become a wholly-owned subsidiary of Eagle.

Eagle Nuclear Energy Corp. is a next-generation nuclear energy company that combines domestic uranium exploration with access to proprietary Small Modular Reactor technology. Eagle owns a conventional uranium deposit in the United States, located in southeastern Oregon. This includes the Aurora deposit, with a current Indicated resource of 53.43 Mt at 278 ppm containing 32.75Mlbs of U₃O₈ and an Inferred resource of 8.96Mt at 252 ppm containing 4.98Mlbs of U₃O₈, as reported in Eagle’s SK-1300 technical report summary dated August 8, 2025 (as amended December 17, 2025), as well as the adjacent Cordex claims, which Eagle believes offers exploration potential and accretive value to shareholders. By integrating advanced SMR technology with a sizeable uranium asset, Eagle is building an integrated nuclear platform positioned to support domestic nuclear energy development.

The Proposed Transaction

Pursuant to the terms of the Proposed Transaction, each common share of the Company would entitle its holder to receive 0.0167 of a common share of Eagle. The Exchange Ratio reflects an offer price of CAD $0.125 per Noble Plains Share, being a premium of approximately 92% to the closing price of the Noble Plains Shares on the TSX Venture Exchange on October 29, 2026 of CAD $0.065.

The LOI provides for the parties to negotiate and enter into a definitive arrangement agreement setting out the final terms and conditions of the Proposed Transaction. Upon execution of the Arrangement Agreement, the Company will issue a subsequent news release containing the details of the Arrangement Agreement and any additional terms of the Proposed Transaction.

“Eagle Nuclear’s offer follows a site visit, a review of our technical data and meetings with our team. Their Offer Price represents a premium of approximately 92% to our October 29 closing price which management believes speaks to the quality of our projects. Our team has built that value on our projects in the prominent Powder River and Shirley Basins. Earlier this year we put out a maiden resource at Duck Creek with additional trend along strike and the deeper Fort Union Formation has not yet been drill tested. At Shirley Central, all seven recent confirmation holes intersected uranium mineralization. ,” stated Drew Zimmerman, President and CEO of Noble Plains. “What they need now is scale and capital, and Eagle Nuclear brings both, along with a team that knows how to advance uranium projects. Our shareholders keep their upside in Wyoming, add exposure to Aurora, a conventional uranium deposit in America, and gain the scale and market access of a Nasdaq-listed company. Together, we have a clear path to grow compliant pounds, accelerate development and help deliver the domestic uranium supply the United States needs. Bigger platform, same discipline, and Noble shareholders own a piece of all of it.”

“This transaction gives Eagle greater scale at a time when the need for domestic U.S. uranium production is growing,” said Mark Mukhija, CEO of Eagle Nuclear Energy. “Noble Plains adds established resources in Wyoming and strengthens our portfolio with favorable ISR geology. We believe we can move these assets forward efficiently while we continue to work towards development of an integrated nuclear energy platform combining domestic uranium resources with advanced SMR technology.”

Details of the Proposed Transaction

The Proposed Transaction is expected to be completed by way of a court-approved plan of arrangement under the Business Corporations Act (British Columbia). Under the terms of the LOI, Eagle, directly or through a wholly owned subsidiary, would acquire all of the issued and outstanding Noble Plains Shares in exchange for Eagle Shares on the basis of the Exchange Ratio. Outstanding Noble Plains stock options are expected to be exchanged for replacement options to acquire Eagle Shares, with the number of underlying shares and exercise price adjusted based on the Exchange Ratio. Outstanding Noble Plains share purchase warrants are expected to remain outstanding in accordance with their terms and, following completion of the Proposed Transaction, are expected to entitle their holders to receive the number of Eagle Shares that they would have received had the warrants been exercised immediately before completion of the Proposed Transaction.

Noble Plains and Eagle expect there will be 89,631,808 Noble Plains Shares and 29,798,342 Eagle Shares issued and outstanding immediately prior to the closing of the Proposed Transaction. Following completion of the Proposed Transaction, it is expected that there will be 31,295,193 Eagle Shares issued and outstanding.

Under the LOI, 60% of the Eagle Shares issued to directors, officers and shareholders of Noble Plains identified by Eagle will be subject to contractual resale restrictions for six months following completion of the Proposed Transaction.

Arrangement Agreement and Due Diligence

The Arrangement Agreement is expected to contain conditions to closing and representations, warranties and covenants customary for transactions of this nature.

The LOI also provides for reciprocal break fees of US$400,000 payable in certain circumstances.

Except for the provisions expressly identified as binding in the LOI, neither Noble Plains nor Eagle is obligated to complete the Proposed Transaction unless and until the parties execute and deliver the Arrangement Agreement, and then only on the terms and subject to the conditions contained in the Arrangement Agreement. There can be no assurance that an Arrangement Agreement will be entered into on the terms contemplated by the LOI, or at all.

Conditions to Completion

Completion of the Proposed Transaction will be subject to customary closing conditions and receipt of necessary shareholder, court and regulatory approvals, including acceptance by the TSXV and approval by Nasdaq of the listing of the Eagle Shares issuable in connection with the Proposed Transaction.
