Acquisition of Fusion Pharmaceuticals Completed

HAMILTON, ON and BOSTON, June 4, 2024 /PRNewswire/ -- Fusion Pharmaceuticals Inc. (Nasdaq: FUSN), a clinical-stage oncology company focused on developing next-generation radioconjugates (RCs), announced the successful completion of the acquisition of all of the issued and outstanding shares of Fusion by a wholly-owned subsidiary of AstraZeneca AB by way of a statutory plan of arrangement under section 192 of the Canada Business Corporations Act, referred to as the Arrangement. The Arrangement marks a major step forward in AstraZeneca delivering on its ambition to transform cancer treatment and outcomes for patients by replacing traditional regimens like chemotherapy and radiotherapy with more targeted treatments.

The Arrangement complements AstraZeneca's leading oncology portfolio with the addition of the Fusion pipeline of RCs, including their most advanced program, FPI-2265, a potential new treatment for patients with metastatic castration-resistant prostate cancer (mCRPC), and brings new expertise and pioneering R&D, manufacturing and supply chain capabilities in actinium-based RCs to AstraZeneca. The Arrangement is also expected to strengthen AstraZeneca's presence in and commitment to Canada.

As a result of the Arrangement, Fusion has become a wholly owned subsidiary of AstraZeneca, with operations continuing in Canada and the US. Fusion shares will be delisted from the Nasdaq Stock Market and deregistered under the U.S. Securities Exchange Act of 1934. Fusion has submitted an application to cease to be a reporting issuer under applicable Canadian securities laws and to otherwise terminate Fusion's Canadian public reporting requirements.

Financial Considerations
Under the terms of the definitive agreement, AstraZeneca, through a subsidiary, has acquired all of Fusion's outstanding shares pursuant to the Arrangement for a price of $21.00 per share in cash at closing plus a non-transferable contingent value right of $3.00 per share in cash payable upon the achievement of a specified regulatory milestone prior to August 31, 2029. Combined, the upfront payment and maximum potential contingent value payment, if achieved, represent a transaction value of approximately $2.4 billion. As part of the Arrangement, AstraZeneca acquired the cash, cash equivalents and short-term investments on Fusion's balance sheet, which totaled $211 million as of March 31, 2024. 

The upfront consideration has been provided to Equiniti Trust Company, LLC, as depositary under the Arrangement, and, along with the contingent value rights, will be delivered to former securityholders (as applicable) of Fusion as soon as practicable on or after the date hereof.

Notes

Radioconjugates in oncology
RCs combine the precise targeting of antibodies, small molecules or peptides with potent medical radioisotopes to deliver radiation directly to cancer cells. By seeking out cancer cells, RCs provide a more precise mechanism of cancer cell killing compared with traditional radiation therapy, with the goal of improving efficacy while minimizing toxicity on healthy cells. RCs are administered via systemic delivery, which enables their use in tumour types not accessible to external beam radiation and the targeting of cancer cells that have spread from the main tumour to other sites in the body.

About FPI-2265
FPI-2265 is an actinium-225 based PSMA-targeting RC for mCRPC, currently in a Phase II trial.

Actinium-225 emits alpha particles and holds the promise of being a next-generation radioisotope in cancer treatment. By delivering a greater radiation dose over a shorter distance, alpha particles such as actinium-225 have the potential for more potent cancer cell killing, and targeted delivery, thereby minimizing damage to surrounding healthy tissue.
