Share Buyback Programme

London Stock Exchange Group plc (LSEG) announces that it is to commence a £200 million buyback programme to repurchase ordinary shares in the capital of LSEG, to be carried out in two tranches (the Programme). The Programme will be managed by Barclays Capital Securities Limited (Barclays) and RBC Europe Limited (RBC). The sole purpose of the Programme is to reduce the share capital of LSEG.

LSEG announces that it has entered into an irrevocable, non-discretionary arrangement with Barclays in relation to the first tranche of the Programme (the First Tranche). Barclays will make its trading decisions concerning the timing of the purchases of LSEG shares independently of and uninfluenced by LSEG.

The First Tranche commences on 30 March 2017 and will end no later than 13 July 2017. Purchases may continue during any closed periods of LSEG which may fall during this period. The maximum amount allocated to the First Tranche is £100 million.

In addition, LSEG announces that it has entered into an irrevocable, non-discretionary arrangement with RBC in relation to the second tranche of the Programme (the Second Tranche). RBC will make its trading decisions concerning the timing of the purchases of LSEG shares independently of and uninfluenced by LSEG.

The Second Tranche will commence on the business day following the end of the First Tranche and will end no later than 14 October 2017. Purchases may continue during any closed periods of LSEG which may fall during this period. The maximum amount allocated to the Second Tranche is £100 million.

The purchased shares will be held as treasury shares. The number of ordinary shares purchased under the Programme will not exceed the maximum number of ordinary shares permitted to be purchased under the authority to purchase shares in LSEG granted by shareholders at LSEG's most recent Annual General Meeting from time to time (the AGM Authority), which is currently 34,800,000 shares. A renewed authority to purchase shares up to a maximum of 35,040,453 shares will be voted on by shareholders at LSEG's Annual General Meeting on 26 April 2017.

Any purchases of ordinary shares by LSEG in relation to the Programme will be effected within certain pre-set parameters and in accordance with the AGM Authority, the Market Abuse Regulation 596/2014 and Chapter 12 of the Listing Rules and will be discontinued in the event LSEG ceases to have the necessary general authority to repurchase ordinary shares. The arrangements with Barclays and RBC are each capable of termination in certain circumstances.
