As previously disclosed, on March 18, 2024, Fusion Pharmaceuticals Inc. (“Fusion”), a corporation formed under the Canada Business Corporations Act (the “CBCA”) entered into a definitive arrangement agreement (the “Arrangement Agreement”) with AstraZeneca AB, a public company with limited liability (Aktiebolag) incorporated under the laws of Sweden (“Parent”) and 15863210 Canada Inc., a corporation formed under the CBCA (“Purchaser”), under which Purchaser will acquire all of the issued and outstanding common shares of Fusion by way of a plan of arrangement under the CBCA (the “Arrangement”).

The expiration of the waiting period under the HSR Act satisfies one of the conditions to the closing of the Arrangement Agreement, which remains subject to other customary closing conditions, including receipt of approval of Fusion’s shareholders (the “Shareholders”).
