Eagle Nuclear Energy Signs Binding LOI to Acquire Noble Plains Uranium

Proposed Acquisition Strategically Expands Eagle’s Domestic Uranium Resource Portfolio

RENO, Nev., Nov. 04, 2026 (GLOBE NEWSWIRE) -- Eagle Nuclear Energy Corp. (“Eagle” or the “Company”) (NASDAQ: NUCL), a next-generation nuclear energy company, today announced that it has signed a binding Letter of Intent (LOI) to acquire 100% of Noble Plains Uranium Corp. (TSX-V: NOBL, OTCQB: NBLXF, FSE: INE0) (“Noble Plains”) in an all-stock transaction, subject to the negotiation and execution of a definitive agreement and customary closing conditions.

Noble Plains is a U.S.-focused uranium exploration and development company advancing two In-Situ Recovery (ISR)-amenable projects strategically located within two of the country’s most prolific uranium districts in Wyoming. ISR provides the most capital-efficient and environmentally responsible method of uranium extraction, while also offering faster development times and lower capital intensity than conventional mining. Noble Plains’ ISR portfolio combines brownfield projects covering ~5,965 acres of demonstrated ISR geology in close proximity to established operators.

Noble Plains has an option to acquire an 80% interest in its flagship Duck Creek project located in the uranium-rich Powder River basin of Wyoming that hosts a U₃O₈ resource, reported on a 100% basis, containing 5.32M lbs in the Indicated category and an additional 1.04M lbs in the Inferred category, as reported by Noble Plains under the Canadian National Instrument 43-101 (“NI 43-101”) regulatory standards (see “Cautionary Note to U.S. Investors Regarding Mineral Resource Estimates” below). Eagle’s technical team believes this current resource estimate represents a relatively small portion of the total resource potential at Duck Creek, as it covers only 2.5 miles of a total 5.25-mile trend, and sits entirely in the shallower of two prospective mineralized formations. Eagle plans to unlock significantly more value at Duck Creek through the execution of a systematically phased exploration program over the next 12-18 months.

Noble Plains’ Shirley Central is an earlier-stage uranium project that represents additional prospectivity for developing U₃O₈ resources in the strategically prominent Shirley basin of Wyoming.

Neither Eagle nor Noble Plains has completed a technical report or resource estimate of Noble Plains’ projects in accordance with Regulation S-K 1300 Standards of Disclosure for Mineral Projects at this time.

Transaction Overview

Under the LOI and subject to a definitive agreement, Eagle will acquire 100% of Noble Plains’ issued and outstanding common shares at a deemed price of CAD $0.125 per Noble Plains’ share. Based on the Exchange Ratio of 0.0167 Eagle shares for each Noble Plains share, the offer price represents a premium of approximately 92% to the closing price of Noble Plains shares on the TSXV on October 29, 2026 of CAD $0.065. Upon closing of the transaction, subject to customary board, stock exchange and any necessary regulatory and shareholder approvals, it is anticipated that existing Eagle stockholders will hold approximately 95.22% and former Noble Plains shareholders will hold approximately 4.78% of the equity of Eagle, on an issued and outstanding share basis.

Strategic Rationale for the Acquisition

• Jurisdictional diversification within the US. This acquisition diversifies Eagle’s domestic uranium resource footprint within the US to include Wyoming in addition to Oregon.
• Entry into two historically prolific uranium districts. Wyoming has produced over 238M lbs of uranium since 1951, and the Powder River and Shirley basins represent two of the most strategically important uranium districts within the state.
• Adding ISR potential to existing conventional potential at Aurora. Developing a portfolio of uranium projects that include ISR-amenability along with conventional mineability diversifies Eagle’s geological and developmental risks, and provides exposure to potentially lower cost and shorter lead-time production opportunities.
• Overall resource growth. The addition of Duck Creek, subject to the exercise of Noble Plains’ option on the project, is expected to provide a meaningful increase to the overall uranium resource attributable to Eagle, with the potential for further resource expansion based on Duck Creek’s high prospectivity.

“This transaction gives Eagle greater scale at a time when demand for U.S. uranium 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.”

“We’ve proven we can acquire uranium assets with historical data, move them forward quickly and add value without having to recreate decades of work,” said Drew Zimmerman, CEO of Noble Plains. “Combining with Eagle gives us more scale and the capital to keep executing that strategy. We have a strong resource at Duck Creek, more opportunity across the portfolio and existing uranium infrastructure all around us. Today’s announcement is a significant inflection point in the development of our assets and we look forward to further building alongside the team at Eagle.”

About Eagle Nuclear Energy Corp.

Eagle Nuclear Energy Corp. is a next-generation nuclear energy company that combines domestic uranium exploration with access to proprietary Small Modular Reactor (SMR) technology. The Company owns the largest conventional, measured and indicated uranium deposit in the United States, located in southeastern Oregon. This includes the Aurora deposit, with 32.75Mlbs Indicated and 4.98Mlbs Inferred (SK-1300 TRS) of near-surface uranium resource, and the adjacent Cordex deposit, which the Company believes offers potential to expand the project’s overall resource inventory. By integrating advanced SMR technology with a sizeable uranium asset, Eagle is building an integrated nuclear platform positioned to support domestic nuclear energy development.

Cautionary Note to U.S. Investors Regarding Mineral Resource Estimates

The Duck Creek mineral resource estimates in this press release were prepared by or on behalf of Noble Plains in accordance with NI 43-101, which differs from subpart 1300 of Regulation S-K (“S-K 1300”), under which Eagle reports its own mineral resources. A qualified person has not done sufficient work on behalf of Eagle to classify these estimates as current mineral resources under S-K 1300, and Eagle is not treating them as current mineral resources of Eagle.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. Inferred mineral resources are subject to a high degree of uncertainty as to their existence and as to whether they can be economically or legally mined, and investors should not assume that any part of an inferred mineral resource will be upgraded to a higher category. The Duck Creek estimates are reported on a 100% basis; Noble Plains’ interest in Duck Creek is subject to its option to acquire an 80% interest.
