ASCENTIAL PLC

PUBLICATION OF CLASS 1 CIRCULAR AND NOTICE OF GENERAL MEETING

Further to the announcement on 30 October 2023 by Ascential plc ("Ascential" or the "Company") regarding the proposed disposals of the Company's digital commerce business ("Digital Commerce") to Omnicom Group Inc.  (the "Digital Commerce Sale"), and its product design business ("WGSN") to Wind UK Bidco 3 Limited (the "WGSN Sale" and, together with the Digital Commerce Sale, the "Transactions"), the Company is pleased to announce that a shareholder circular relating to the Transactions has been approved by the Financial Conduct Authority and will shortly be sent to the Company's shareholders (other than those who have elected for notification by electronic communication).

Each of the Digital Commerce Sale and the WGSN Sale qualifies as a "Class 1" transaction for the Company under the Listing Rules and accordingly, each of the Digital Commerce Sale and the WGSN Sale is conditional upon, amongst other things, the approval of the Company's shareholders at a general meeting of the Company. Accordingly, the Circular contains a notice convening a general meeting of the Company which is to be held at the offices of Slaughter and May, One Bunhill Row, London EC1Y 8YY on 18 December 2023 at 10.00am (the "General Meeting"), at which the resolutions contained in the notice of meeting will be proposed to the Company's shareholders to approve the Transactions (the "Resolutions").

The Board considers the Transactions (and the Resolutions necessary to implement the Transactions) to be in the best interests of the Company and its shareholders as a whole and unanimously recommends that shareholders vote in favour of the Resolutions at the General Meeting.

A copy of the Circular will be submitted to the National Storage Mechanism where it will be available for inspection at https://data.fca.org.uk/#/nsm/nationalstoragemechanism. In addition, a copy of the Circular will be made available for inspection on the Company's website at www.ascential.com.
