Transaction in Own Shares, Completion of Share Buyback Programme and Total Voting Rights

The Company announces that on 9 September 2026, in accordance with the terms of its share buyback programme announced on 19 February 2026 (the “Share Buyback”), the Company has purchased 72,916 ordinary shares of nominal value of £0.2625 each in the capital of the Company (the "OrdinaryShares") on the London Stock Exchange through Merrill Lynch International (“BofA Securities”).

The Share Buyback is to enable the Company to issue Ordinary Non-Voting shares to Amundi equal to the number of Ordinary Shares repurchased by the Company in a manner that is non-dilutive to the Company’s existing shareholders in connection with its strategic partnership with Amundi as announced on 18 November 2025 (the “Strategic Partnership Announcement”).

Completion of Share Buyback Programme

The Company confirms that, following the purchase of the Ordinary Shares disclosed above, the Share Buyback has now concluded. Since the commencement of the Share Buyback, the Company has repurchased 15,280,825 Ordinary Shares in aggregate at a weighted average price of 1790.56 pence per Ordinary Share for a total consideration of approximately £274 million. In accordance with the Subscription Agreement, Amundi has subscribed for an equivalent number of Ordinary Non-Voting shares. The subscription price for those Ordinary Non-Voting shares was equal to the repurchase price for the Ordinary Shares, and Amundi will reimburse the Company in cash for the costs and expenses incurred in connection with the Share Buyback.

As a result of the completion of the Share Buyback, Amundi has a 9.9% economic interest in the Company, including a 4.9% voting interest. The Ordinary Shares and Ordinary Non-Voting shares have the same economic entitlements, including as relates to dividends. Shareholders may therefore use the figure of 290,644,122 (being the combined number of Ordinary Shares and Non-Voting Ordinary shares outstanding) to assess their economic interest in the Company.

Cancellation of Treasury Shares and Total Voting Rights

The Company confirms that on 16 September 2026, following the completion of the Share Buyback, it cancelled 6,897,364 Ordinary Shares held in Treasury. Following the cancellation, the Company has 275,363,297 Ordinary Shares in issue and 15,280,825 Ordinary Non-Voting shares in issue.

Therefore, the total number of voting rights in the Company is 275,363,297, and this figure may be used by Shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company under the FCA's Disclosure Guidance and Transparency Rules.

No Ordinary Shares or Ordinary Non-Voting shares are currently held in Treasury.

Terms not defined here shall have the meaning as set out in the Strategic Partnership Announcement.
