Mural Oncology Announces Sanction of the Scheme by the High Court
WALTHAM, Mass. and DUBLIN, Dec. 03, 2025 (GLOBE NEWSWIRE) -- Mural Oncology plc, (Nasdaq: MURA) (“Mural”) announces that the High Court of Ireland has today sanctioned the scheme of arrangement between Mural and its shareholders under Chapter 1 of Part 9 of the Companies Act 2014 (the “Scheme”) pursuant to which XRA 5 Corp. (“Sub”), a wholly-owned subsidiary of XOMA Royalty Corporation (Nasdaq: XOMA) (“XOMA Royalty”), will acquire the entire issued and to be issued share capital of Mural (the “Acquisition”).
The Scheme and the Acquisition will become effective on delivery of the Court Order to the Irish Registrar of Companies.
Delivery of the Court Order to the Irish Registrar of Companies is expected to occur, and the Acquisition is expected to become effective, on 5 December 2025 (the “Effective Date”). Accordingly, 4 December 2025 is expected to be the last date on which trading of Mural Shares on the Nasdaq will occur. Cancellation of the admission of Mural Shares to trading on the Nasdaq Global Market is expected to occur with effect from 8.00 pm (U.S. Eastern Time) on 4 December 2025.
Distribution of cheques and crediting of DTC participant accounts for the cash consideration paid by Sub to Scheme Shareholders under the terms of the Scheme is expected to commence as soon as practicable following the Effective Date, with DTC participant accounts expected to be credited and the distribution of cheques expected to be complete as soon as practicable. In accordance with the requirements of the Irish Takeover Rules, subject to the delivery of the Court Order to the Irish Registrar of Companies on 5 December 2025, all consideration payable by Sub to Scheme Shareholders under the terms of the Scheme will be distributed by no later than 19 December 2025.
Except as otherwise defined herein, capitalised terms used but not defined in this announcement have the same meanings as given to them in the definitive proxy statement of Mural dated 23 September 2025 relating to the Acquisition, which also constitutes a scheme circular under Irish law.
