Eagle Nuclear Energy is a next-generation nuclear energy company that combines domestic uranium exploration with access to proprietary small modular reactor (SMR) 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 (million tonnes) at 278 ppm (parts per million) containing 32.75 Mlb (million pounds) of U3O8 (triuranium octoxide) and an inferred resource of 8.96 Mt at 252 ppm containing 4.98 Mlb of U3O8, as reported in Eagle's SK-1300 technical report summary dated Aug. 8, 2025 (as amended Dec. 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 12.5 cents per Noble Plains share, being a premium of approximately 92 per cent to the closing price of the Noble Plains shares on the TSX Venture Exchange on Oct. 29, 2026, of 6.5 cents.

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 per cent 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 chief executive officer 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 favourable 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."

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.
