LONDON STOCK EXCHANGE GROUP PLC

("LSEG" or the "Company")

Capital Reduction

LSEG announces that the reduction of capital approved by shareholders at the Annual General Meeting of the Company held on 23 April 2026 (the Capital Reduction) was on 2 June 2026 approved by the High Court of Justice of England and Wales (the Court). The Court order approving the Capital Reduction, and a statement of capital approved by the Court, have been registered with the Registrar of Companies and accordingly the Capital Reduction has now become effective.

The purpose of the Capital Reduction is to increase the amount of distributable reserves available for the Company to provide flexibility for future dividends and share buybacks. This has been effected by: (i) converting part of the Company's merger relief reserve into share capital by issuing one B ordinary share having a nominal value of £10,347 million (the Capital Reduction Share) and then cancelling the Capital Reduction Share; and (ii) cancelling the full amount standing to the credit of the Company's share premium account (being £977,839,016.67). There is no change in the number of the Company's ordinary shares in issue, or their nominal value, as a result of the Capital Reduction.
