Scheme of Arrangement becomes Effective

On 7 April 2026, the boards of Senior and BidCo announced that they had reached agreement on the terms of a recommended cash acquisition pursuant to which BidCo shall acquire the entire issued and to be issued ordinary share capital of Senior (other than the Existing Tinicum Shares) (the "Acquisition").

The Acquisition is being implemented by means of a court-sanctioned scheme of arrangement under Part 26 of the Companies Act 2006 (the "Scheme") and is subject to the terms and conditions set out in the circular in relation to the Scheme sent to Senior Shareholders dated 30 April 2026 (the "Scheme Document").

On 6 October 2026, Senior and BidCo announced that the Court had sanctioned the Scheme at the Sanction Hearing held on 6 October 2026.

Senior and BidCo are pleased to announce that, following delivery of the Court Order to the Registrar of Companies today, the Scheme has now become Effective in accordance with its terms and the entire issued share capital of Senior is now owned by BidCo (other than the Existing Tinicum Shares).

Consideration and settlement

Under the terms of the Scheme, a Scheme Shareholder on the register of members of Senior at the Scheme Record Time, being 6.00 p.m. on 7 October 2026, will be entitled to receive 297.85 pence in cash for each Scheme Share held. Settlement of the consideration to which any Scheme Shareholder is entitled will be effected as set out in the Scheme Document.
