TORONTO, June 25, 2026 /PRNewswire/ - IsoEnergy Ltd. ("IsoEnergy") (NYSE:ISOU) (TSX:ISO) is pleased to announce the completion of its previously announced acquisition of Toro Energy Limited ("Toro") (ASX: TOE) by way of a scheme of arrangement under Australia's Corporations Act 2001 (Cth) (the "Transaction" or the "Scheme"). Pursuant to the Scheme, IsoEnergy has acquired all of the issued and outstanding ordinary shares of Toro that it does not already own (the "Toro Shares"). The Scheme was implemented today following approval by Toro shareholders on June 9, 2026, and approval by the Federal Court of Australia on June 15, 2026. The Scheme became effective on June 16, 2026.

Under the terms of the Scheme, eligible participating Toro shareholders received 0.036 of a common share of IsoEnergy (each whole share, an "ISO Share") for each Toro Share held on the Scheme record date. As a result of the implementation of the Scheme, IsoEnergy has issued approximately 4,359,568 ISO Shares to former eligible Toro shareholders.

Philip Williams, Chief Executive Officer and Director of IsoEnergy, commented, "The completion of the Toro acquisition marks another important step in advancing IsoEnergy's strategy to build a globally diversified, development-ready uranium platform. The addition of the Wiluna Uranium Project expands and diversifies our development pipeline, complementing our flagship Hurricane project in the Athabasca Basin. With growing support for nuclear energy and increasingly constructive policy and market conditions for uranium development in Australia, we believe this Transaction positions IsoEnergy to benefit from multiple avenues of future growth. We are pleased to welcome Toro shareholders to IsoEnergy and look forward to advancing the combined portfolio."

Toro Shares were suspended from trading on the Australian Securities Exchange ("ASX") as at close of trading on June 16, 2026, and Toro is expected to be removed from the official list of the ASX on or about June 26, 2026.

For additional information on the Transaction, please refer to IsoEnergy's news releases dated October 12, 2025 and June 10, 2026.
