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

TORONTO, Nov. 10, 2026 (GLOBE NEWSWIRE) -- Premier American Uranium Inc. (“PUR”, the “Company” or “Premier American Uranium”) (TSXV: PUR) (OTCQB: PAUIF) is pleased to announce that it has closed its previously announced strategic equity investment by DISA Uranium Corporation (“DISA Uranium”), pursuant to which PUR issued 9,326,000 subscription receipts (the “Subscription Receipts”) to DISA Uranium at C$0.75 per Subscription Receipt (the “Offering Price”) for aggregate proceeds of US$5,000,000 (C$6,994,500) (the “Equity Investment”). Upon conversion of the Subscription Receipts, DISA Uranium is expected to hold an approximately 8.88% ownership interest in PUR. The Offering Price represents a 41.5% premium to the closing price of PUR’s common shares (the “PUR Shares”) on September 14, 2026, the last trading day prior to the announcement of the Equity Investment.

The Company is also pleased to announce that IsoEnergy Ltd. (“IsoEnergy”), a founding and strategic shareholder of PUR, has agreed to acquire the position held by Sachem Cove Opportunity Fund LP (“Sachem Cove”), comprising 13,642,775 PUR Shares (the “IsoEnergy Acquisition”). As consideration, IsoEnergy issued 387,491 of its common shares to Sachem Cove. Following completion of the IsoEnergy Acquisition, IsoEnergy will hold 21,136,376 PUR Shares, representing approximately 22.1% of the outstanding PUR Shares on a non-diluted basis, and warrants to acquire an additional 3,060,127 PUR Shares. Following completion of the IsoEnergy Acquisition, Sachem Cove will no longer hold any securities of PUR. PUR did not issue any securities or receive any proceeds in connection with this transaction.

Colin Healey, CEO of PUR, commented, “We appreciate the continued confidence and support of DISA Uranium and IsoEnergy. DISA Uranium’s US$5 million strategic investment, priced at a 41.5% premium to PUR’s closing share price immediately before its announcement, alongside IsoEnergy’s increased ownership, represents a strong endorsement of our assets, team and strategy. Their support strengthens our position as we advance our U.S. uranium development and ISR exploration portfolio.”

Mr. Healey continued, “We also thank Sachem Cove for its instrumental role in establishing PUR and building the foundation we have today. Its original vision was to build a meaningful U.S. uranium platform and attract strategic partners to support its growth. The transfer of its position to IsoEnergy is consistent with Sachem Cove’s broader macro-focused investment approach, while strengthening the commitment of a founding strategic shareholder as PUR enters its next phase of growth.”

DISA Uranium Strategic Equity Investment

Each Subscription Receipt entitles DISA Uranium to automatically receive, upon satisfaction or waiver, as applicable, of certain escrow release conditions (the “Escrow Release Conditions”), one PUR Share.

The Escrow Release Conditions include the satisfaction of all conditions precedent to the completion of the previously announced transaction pursuant to which the Company has agreed to sell all of its rights, title and interest in and to the Outlaw Mesa, Atkinson Mesa, Monogram Mesa and Slick Rock Projects located in Colorado to DISA Uranium (the “Transaction”). The proceeds of the Equity Investment are being held in escrow and will not be released to PUR until the Escrow Release Conditions are satisfied or waived, as applicable. If the Escrow Release Conditions have not been satisfied or waived, as applicable, on or prior to June 13, 2027, the aggregate Offering Price of the Subscription Receipts (plus any interest earned thereon) will be returned to DISA Uranium, and the Subscription Receipts will be automatically cancelled and be of no further force and effect.

Following the satisfaction or waiver, as applicable, of the Escrow Release Conditions, the proceeds of the Equity Investment are expected to be used by the Company to fund proposed exploration and development programs for PUR’s projects as well as for working capital and general corporate purposes. Completion of the Equity Investment is subject to the final approval of the TSX Venture Exchange. The Subscription Receipts and the PUR Shares issuable upon conversion thereof are subject to a hold period expiring on March 10, 2027.

Related Party Disclosure

An insider of the Company, IsoEnergy is also an insider of DISA Uranium, and therefore the Equity Investment constitutes a “related party transaction” pursuant to Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions (“MI 61-101”). The Company is exempt from the requirement to obtain a formal valuation or minority shareholder approval in connection with the Equity Investment under MI 61-101 in reliance on Sections 5.5(a) and 5.7(1)(a) of MI 61-101 due to the fair market value of the Equity Investment being below 25% of the Company’s market capitalization for purposes of MI 61-101. The Transaction and the Equity Investment have been approved by the board of directors of the Company with Marty Tunney, a director of the Company and officer of IsoEnergy, having disclosed his interest and abstaining from voting thereon. The Company has not received, nor has it requested a valuation of its securities or the subject matter of the Equity Investment in the 24 months prior to the date hereof.
