Allocation of the Exit Tender Offer Pools

Further to the announcement of the results of elections pursuant to the Exit Tender Offer on 20 April 2026, the Board now confirms that the Company's Debt Facilities have been repaid in full and that assets and liabilities have been allocated to the Tender Pool and the Continuing Pool in accordance with the terms of the Exit Tender Offer. The value of the assets allocated to the Tender Pool is equal to the Tender Pool Initial Asset Value, which has been calculated in accordance with the terms of the Exit Tender Offer as at close of business on 29 April 2026. The Tender Pool Initial Asset Value was £719.0 million in respect of the 148,202,139 Ordinary Shares that have been validly tendered pursuant to the Exit Tender Offer.

The assets in the Tender Pool will be realised, the relevant liabilities will be settled, the associated costs of the Exit Tender Offer will be paid and, subsequently, the net cash proceeds will be paid to Shareholders who validly elected for the Exit Tender Offer. The Tender Price will be the Tender Pool Final Asset Value divided by the total number of Tender Exit Shares.

As set out in the Circular, the Company has very substantial distributable reserves and it is likely that all of the Shares in respect of which a valid election was made will be accepted as Tender Exit Shares. However, it is not possible to say definitively whether sufficient distributable reserves will be available. Any modest amount of scale back required as a result of insufficient distributable reserves, along with confirmation of the Tender Price, is expected to be announced before the end of May.

The Tender Pool NAV per Share will be announced daily throughout the period of realisation.

Defined terms used in this announcement shall, unless the context requires otherwise, have the meanings ascribed to them in the circular to Shareholders published by the Company on 17 March 2026.
