Special Resolution 9 - Authority to purchase own shares

1. In substitution for all existing authorities to the extent unused, to authorise the Company to make market purchases of its own ordinary shares either for cancellation or to hold as treasury shares for future resale or transfer, provided that:

(a)      the maximum number of ordinary shares authorised to be purchased is 14.99% of the ordinary shares in issue as at 6 August 2025 (being the latest practicable date before the publication of the notice of AGM);

(b)      the minimum price which may be paid for an ordinary share is £0.01;

(c)       the maximum price (exclusive of expenses) which may be paid for an ordinary share must not be more than the higher of (i) 5 per cent. above the average of the mid-market quotations for the five Business Days before the purchase is made; and (ii) the higher of: (a) the price of the last independent trade, and (b) the highest current independent bid for ordinary shares on the London Stock Exchange at the time the purchase is carried out,

and such authority will unless previously revoked or varied, expire at the conclusion of the next annual general meeting of the Company, save that the Company may contract to purchase ordinary shares under the authority thereby conferred prior to the expiry of such authority, which contract will or may be executed wholly or partly after the expiry of such authority and may purchase ordinary shares in pursuance of such contract.

Resolution 9 is to allow the Company to repurchase up to 49,992,856 ordinary shares and replaces the existing authority in this regard. There is no present intention to exercise such general authority. This authority will expire at the conclusion of the next annual general meeting of the Company. The Directors intend to seek renewal of this authority at subsequent annual general meetings in accordance with best practice.

The resolution specifies the maximum number of ordinary shares which may be purchased (representing 14.99% (excluding treasury shares) of the Company's issued ordinary share capital as at 6 August 2025, being the latest practicable date before the publication of the notice of AGM) and the maximum and minimum prices at which they may be bought, exclusive of expenses. General purchases undertaken in accordance with this resolution will only be made through the market.

The Directors undertake that, after considering the maximum number of shares that may be repurchased pursuant to the general authority granted by Resolution 9, and the price at which any such repurchases shall be effected, on the date on which the repurchase is to be effected they will ensure there are reasonable grounds for believing that the Company is, and after the repurchase will continue to be, able to pay its liabilities as they become due.

Under the Companies (Guernsey) Law, 2008, as amended (the "Companies Law"), the Company is allowed to hold its own shares in treasury following a repurchase, instead of having to cancel them. In accordance with the Company's articles of incorporation, the Companies Law and the LSE listing requirements, treasury shares may be resold for cash, used to settle future scrip dividends offered by the Company to its shareholders or used for the exercise of options under employee share schemes. However, all rights attaching to such shares, including voting rights and any right to receive dividends are suspended whilst they are held in treasury. If the Directors exercise the authority conferred by Resolution 9, the Company will have the option of holding them in treasury or cancelling any of its own shares purchased under this authority and will decide at the time of purchase which option to pursue.

The total number of voting rights was 333,508,046 ordinary shares of no par value each.

The full text of all the resolutions can be found in the Notice of Annual General Meeting dated 15 August 2025, a copy of which is available on the Company's website at www.castelnaugroup.com.

In accordance with UK Listing Rule 6.4.3 copies of all the resolutions passed, other than ordinary business, will be submitted to the National Storage Mechanism and will shortly be available for inspection at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism .
