PLACING OF 33.0 MILLION VOTING ORDINARY SHARES IN LONDON STOCK EXCHANGE GROUP PLC ("LSEG" OR THE "COMPANY")

17 May 2023

Further to the announcement released on 16 May 2023, BCP York Holdings (Delaware) L.P. (an entity owned by a consortium of certain investment funds affiliated with Blackstone Inc. ("Blackstone") and including an affiliate of Canada Pension Plan Investment Board, an affiliate of GIC Special Investments Pte. Ltd. and certain other co-investors) ("BCP York"), York Holdings II Limited ("York Holdings II") and York Holdings III Limited ("York Holdings III") (entities owned by BCP York, Thomson Reuters and certain other minority holders) (BCP York, York Holdings II and York Holdings III together, the "Consortium" or the "Sellers") have sold an aggregate of 33,000,000 voting ordinary shares of 6⁷⁹/₈₆ pence each in the capital of the Company at a price of 8,050 pence per ordinary share (the "Placing Price") via a placing to institutional investors (the "Placing") and a separate offer to retail investors (the "Retail Offer") at the Placing Price. The Placing was upsized from 28.0 million voting ordinary shares (as announced on 16 May 2023) to 33.0 million voting ordinary shares.

The aggregate gross sale proceeds raised through the Placing and the Retail Offer are approximately £2.7 billion.

The Placing and the Retail Offer are being undertaken in compliance with the Relationship Agreement (as defined in the Prospectus (see below)), a summary of the terms of which is set out in the prospectus published by LSEG on 9 December 2020 (the "Prospectus"). As detailed in the Relationship Agreement, as of 30 January 2023 the lock-up arrangements governing Blackstone and Thomson Reuters' indirect shareholding in LSEG no longer applied to approximately 66.1 million of the voting ordinary shares owned indirectly by Blackstone and Thomson Reuters (in aggregate) which are free to be sold. In March 2023, the Consortium completed the sale of 28.0 million of such voting ordinary shares, and accordingly prior to the Placing have approximately 38.1 million voting ordinary shares remaining free to be sold in accordance with the Relationship Agreement. The balance of approximately 5.1 million voting ordinary shares owned indirectly by Blackstone and Thomson Reuters not sold in the Placing or the Retail Offer are subject to a 90 day lock-up, subject to customary exceptions and waiver by the Joint Global Coordinators (as defined below). The lock-up also contains an exception for disposals of shares pursuant to share repurchases by the Company.

The Company is not party to the Placing or the Retail Offer and will not receive any proceeds from the Placing or the Retail Offer.

The proceeds of the Placing and the Retail Offer are payable in cash on usual settlement terms, and closing of the Placing and the Retail Offer is expected to occur on a T+2 basis on 19 May 2023, subject to the satisfaction or waiver of certain customary conditions.

Barclays Bank PLC ("Barclays"), Citigroup Global Markets Limited ("Citigroup"), J.P. Morgan Securities plc (which conducts its UK investment banking business as J.P. Morgan Cazenove) ("JPMC") and Merrill Lynch International ("BofA Securities" and, together with Barclays, Citigroup, and JPMC, the "Joint Global Coordinators") are acting as Joint Global Coordinators and Joint Bookrunners in connection with the Placing.
