Premier American Uranium Completes US$5 Million Strategic Equity Investment by DISA Uranium; IsoEnergy Increases its Strategic Holding

Premier American Uranium Inc. (PUR) has closed a US$5.0 million strategic equity investment from DISA Uranium Corporation. Under the terms of the deal, DISA acquired 9,326,000 subscription receipts at C$0.75 each, a price representing a 41.5% premium to PUR's closing price on September 14, 2026.

The proceeds from the investment are held in escrow and will convert into PUR shares once specific conditions are satisfied. The primary condition is the closing of PUR's sale of its Colorado assets—Outlaw Mesa, Atkinson Mesa, Monogram Mesa, and Slick Rock—to DISA. If these closing conditions are not met or waived by June 13, 2027, the funds plus interest will be returned to DISA and the subscription receipts cancelled.

As part of the transaction, founding shareholder IsoEnergy Ltd. acquired the entire stake of Sachem Cove Opportunity Fund LP, increasing IsoEnergy's ownership to approximately 22.1% of outstanding shares. The arrangement is classified as a related-party transaction under Multilateral Instrument 61-101, exempting it from formal valuation and minority shareholder approval requirements. DISA receives customary participation rights and the right to nominate one director to PUR's Board.

Premier American Uranium Inc. (PUR) is set to receive a US$5.0 million capital infusion from the closing of its strategic investment with DISA. These funds will be held securely in escrow until the asset sale to DISA closes, a structure that reduces immediate dilution risk compared to standard open-market financing and aligns capital deployment with the monetization of non-core Colorado projects.

The transaction allows PUR to divest the Colorado portfolio while retaining upside exposure through DISA's equity and warrants, effectively monetizing historical assets without sacrificing future optionality. Concurrently, IsoEnergy’s acquisition of Sachem Cove's stake increases its ownership position to 22.1%, demonstrating strong insider confidence and consolidating strategic control. This level of insider accumulation typically supports long-term holding patterns and reduces float volatility.

The deal carries a 41.5% premium to the pre-announcement share price, validating management's strategic direction and providing a near-term price anchor. Although the market had already priced in the September 15 announcement, the execution of previously disclosed terms confirms the strategic shift.

Premier American Uranium Inc. (PUR) is a U.S.-focused uranium exploration and development company. Its flagship asset is the Cebolleta Uranium Project in New Mexico, a heap-leach operation with a projected 13-year life. A 2025 Preliminary Economic Assessment (PEA) for the project calculated an after-tax net present value (NPV) of $83.9 million at a uranium price of $90/lb U3O8. The project holds an Indicated resource of 20.3 million pounds and an Inferred resource of 7.0 million pounds. Metallurgical testing is currently underway to improve recovery rates from 80% to 90%, a change that could nearly double the NPV to $159 million.

The company also holds the Kaycee ISR Uranium Project in Wyoming, a large grassroots exploration program spanning approximately 31,724 acres across the Powder River Basin. The 2026 program targets 100,000 feet of drilling to define a resource across the Outpost, Rustler, and West Diane targets.

Premier American Uranium has divested its Colorado portfolio, which included the Outlaw Mesa, Atkinson Mesa, Monogram Mesa, and Slick Rock properties, selling them to DISA Uranium to focus capital on its core U.S. assets.
