5 terms

deemed price financial

"deemed price of $11.763 per share"

A deemed price is a notional value assigned to a security or asset when no clear market price exists, used for accounting, tax or corporate-action calculations. Think of it like agreeing on a sticker price for a homemade item when you trade it — the number doesn’t reflect a real market sale but establishes a common reference for calculating taxes, gains, share allocations, or conversion rates. Investors care because that assigned price determines reported gains or losses, how ownership stakes are adjusted, and the cash or share amounts they receive.

partially-diluted basis financial

"approximately 24.5% ... on a partially-diluted basis"

A partially-diluted basis is a way of counting a company’s shares that includes currently outstanding shares plus certain likely additional shares from things like vested options, warrants, and convertible securities, but excludes more speculative or unissued items. For investors it gives a more realistic view of ownership stakes and per-share figures — like earnings per share — by showing dilution that is probable today, much as counting people with purchased tickets (but not those who might buy later) gives a clearer sense of how full a theater really is.

subscription receipts financial

"strategic investment ... in subscription receipts of PUR"

Subscription receipts are temporary securities sold to investors that act like a receipt for future shares or cash once certain conditions in a financing or acquisition are met; until those conditions are satisfied, the funds are held in trust. Think of them as a ticket you buy today that will convert into the actual product later or get you a refund if the event doesn’t happen. They matter to investors because they provide a way to participate in a deal now while limiting immediate ownership changes and risk until the outcome is confirmed.

escrow release conditions financial

"satisfaction or waiver of the applicable escrow release conditions"

Escrow release conditions are the specific checklist of actions, documents or approvals that must be satisfied before money or assets held by a neutral third party are handed over. Think of it like a locked safe that only opens when everyone produces the right keys or paperwork. For investors, these conditions shape when cash or shares change hands, reduce the risk of surprises, and can affect deal timing, expected returns and liquidity.

in-situ recovery technical

"ongoing ISR exploration in Wyoming"

In-situ recovery is a mining method that extracts a valuable material by dissolving it underground and pumping the solution to the surface instead of digging or blasting rock. For investors, it matters because this approach often lowers upfront construction costs, shortens development time and reduces visible land disturbance, but it also brings regulatory, environmental and groundwater risks that can affect project timelines, operating costs and valuation.

Exhibit 99.1

IsoEnergy Increases Strategic Holding in Premier American Uranium Inc.

TORONTO, Nov. 10, 2026 /CNW/ -- IsoEnergy Ltd. ("IsoEnergy", or the "Company") (NYSE American: ISOU) (TSX: ISO) is pleased to announce that it has agreed to acquire (the "Transaction") 13,642,775 common shares (the "PUR Shares") of Premier American Uranium Inc. ("PUR") held by Sachem Cover Opportunity Fund LP ("Sachem Cove") in consideration for the issuance of an aggregate of 387,491 common shares of the Company (the "ISO Shares"). The ISO Shares were issued at a deemed price of $11.763 per share, representing aggregate consideration of $4,558,057. Closing of the Transaction is subject to the satisfaction of certain customary closing conditions, including the approval of the Toronto Stock Exchange with respect to the issuance of the ISO Shares.

The Transaction will transfer Sachem Cove's position in PUR to IsoEnergy, a founding and strategic shareholder, further strengthening IsoEnergy's exposure to U.S. uranium development and in-situ recovery exploration. PUR will not issue any securities or receive any proceeds in connection with the Transaction. The increased investment follows PUR's completion of a US$5 million strategic investment by DISA Uranium Corporation ("DISA Uranium") in subscription receipts of PUR priced at C$0.75 each, representing a 41.5% premium to PUR's closing share price on September 14, 2026, the last trading day before that investment was announced. The subscription receipts will convert into PUR Common Shares upon satisfaction or waiver of the applicable escrow release conditions. IsoEnergy is also a significant shareholder of DISA Uranium (see PUR press releases dated September 15, 2026, and November 10, 2026).

Philip Williams, CEO and Director of IsoEnergy, commented, "We are pleased to increase our position as a strategic shareholder of PUR as it advances the Cebolleta uranium project in New Mexico and pursues significant discovery potential through ongoing ISR exploration in Wyoming. We believe the recent weakness in PUR's share price does not reflect the value of its development portfolio and exploration upside, creating an attractive opportunity to add to our holdings. This transaction further strengthens our exposure to the U.S. uranium sector which spans near-term production, development and exploration through our own portfolio and investments in DISA Uranium and PUR. DISA Uranium's recent investment in PUR further reinforces the strategic support behind PUR as it pursues an exciting next phase of growth."

Immediately prior to the completion of the Transaction, the Company owned an aggregate of 7,493,601 PUR Shares and warrants to acquire 3,060,127 PUR Shares, representing approximately 7.8% of the current outstanding PUR Shares on a non-diluted basis and approximately 10.7% of the current outstanding PUR Shares on a partially-diluted basis assuming exercise of all of the warrants held by the Company.

Assuming completion of the Transaction, the Company is deemed to own an aggregate of 21,136,376 PUR Shares and warrants to acquire an aggregate of 3,060,127 PUR Shares, representing approximately 22.1% of the current outstanding PUR Shares on a non-diluted basis and approximately 24.5% of the current outstanding PUR Shares on a partially-diluted basis assuming exercise of all of the warrants held by the Company.

The securities of PUR held by IsoEnergy are held for investment purposes. Although IsoEnergy has no current plans with respect to the securities, depending on market conditions, general economic and industry conditions, trading prices of PUR's securities, PUR's business, financial condition and prospects and/or other relevant factors, IsoEnergy may develop such plans or intentions in the future and, at such time, may from time to time acquire additional securities, dispose of some or all of the existing or additional securities or may continue to hold securities of PUR. The PUR Shares are being acquired by IsoEnergy pursuant to an exemption under Section 4.2 of National Instrument 62-104 – Take-Over Bids and Special Transactions.

This news release is issued pursuant to National Instrument 62-103 – The Early Warning System and Related Take-Over Bid and Insider Reporting Issues, which also requires an early warning report to be filed with the applicable securities regulators containing additional information with respect to the foregoing matters. A copy of the early warning report of IsoEnergy will be available under PUR's profile on SEDAR+ at www.sedarplus.ca. IsoEnergy's registered office is located at 217 Queen Street West, Toronto, ON M5V 0R2.
