London Stock Exchange Group plc - Commencement of Share Buyback Programme

London Stock Exchange Group plc (the "Company") announces today that, further to its announcement on 27 February 2025 of the Company's preliminary results for the financial year ended 31 December 2024, the Company will commence a share buyback programme to purchase ordinary shares of 679/86 pence each in the Company ("Shares") with an aggregate value of up to £500 million (the "Buyback Programme").

In connection with the Buyback Programme, the Company has entered into an irrevocable agreement with Morgan Stanley & Co. International Plc ("Morgan Stanley") in relation to the purchase of Shares by Morgan Stanley, acting as riskless principal and in accordance with certain pre-set parameters, under which the Company has instructed Morgan Stanley to purchase Shares with a value of up to £500 million. Purchases will commence immediately and will end no later than 30 July 2025. Morgan Stanley will make trading decisions in relation to the Buyback Programme independently of, and uninfluenced by, the Company. Any purchase of Shares by Morgan Stanley contemplated by this announcement will be carried out on the London Stock Exchange and/or on Turquoise Equities Trading. Shares purchased by Morgan Stanley will be on-sold by Morgan Stanley to the Company, and any purchases of Shares by the Company from Morgan Stanley will be carried out on the London Stock Exchange, with the Shares purchased by the Company being held in treasury. The arrangements between the Company and Morgan Stanley are subject to customary termination rights in favour of the Company and Morgan Stanley. The purpose of the Buyback Programme is to reduce the share capital of the Company. 

Any purchases under the Buyback Programme shall take place in accordance with (and subject to the limits prescribed by) the Company's general authority to repurchase Shares granted by its shareholders at the annual general meeting on 25 April 2024 (the "2024 Authority") and any further authority to repurchase Shares as may be granted by its shareholders from time to time under Chapter 9 of the Listing Rules. The maximum number of Shares that the Company is authorised to purchase under the 2024 Authority is 53,560,181. Purchases of Shares by Morgan Stanley shall take place in accordance with the Market Abuse Regulation (EU) No 596/2014 (including the delegated and implementing acts adopted under it) and the Commission Delegated Regulation (EU) No 2016/1052 with regard to regulatory technical standards for the conditions applicable to buyback programmes and stabilisation measures (in each case as they form part of the law of the United Kingdom by virtue of the European Union (Withdrawal) Act 2018, as implemented, retained, amended, extended, re-enacted or otherwise given effect in the United Kingdom from 1 January 2021 and as amended or supplemented in the United Kingdom thereafter). The Company will make further regulatory announcements to shareholders in respect of purchases of Shares under the Buyback Programme as they occur.
