Update on Share Buyback Extension

In its 2024 Preliminary Results on 20 February 2025, the Company announced a further £500 million extension of the Company's share buyback programme, to be completed by around the end of 2025 (the "2025 Extension"), taking the total programme to £2.0bn.

The Company today announces the entry into an irrevocable arrangement with Goldman Sachs International ("Goldman Sachs") (acting as riskless principal) to conduct the repurchases in respect of the first £250 million tranche of the 2025 Extension (the "First Tranche") on its behalf and to make trading decisions in respect of the First Tranche independently of the Company.

Repurchases in respect of the First Tranche will be conducted from 16 June 2025 to no later than 19 September 2025 to buy back ordinary shares of 6 14/81 pence each (the "Shares") up to an aggregate maximum consideration of up to £250 million (exclusive of associated fees, expenses and stamp duty), representing an amount equal to the aggregate value of approximately 3% of the Company's issued share capital at the share price as at close of business on 7 May 2025.

Goldman Sachs International may effect purchases of shares under the First Tranche on the London Stock Exchange and/or other trading venues[1] for subsequent purchase by the Company. Purchases by the Company will be treated as being made on the London Stock Exchange. The Company intends that any shares purchased will be cancelled, held in treasury, or used for the purposes of employee share schemes.

The purpose of the 2025 Extension is to reduce the capital of the Company.

Any share purchases will be carried out in accordance with certain pre-set parameters. The maximum number of ordinary shares which may be purchased by the Company under the First Tranche is 536,039,506 (which is the maximum pursuant to the authority granted by shareholders at the Company's Annual General Meeting held on 5 June 2024) less the number of Shares purchased (and to be purchased) by the Company pursuant to the share buyback programmes announced on 8 August 2024 and 27 December 2024 taken together with such number of Shares under any subsequent authority to repurchase Shares as may be granted by the Company's shareholders at the Company's Annual General Meeting to be held on 8 May 2025.

The First Tranche will be conducted within the parameters prescribed by the Market Abuse Regulation 596/2014/EU (as in force in the UK and as amended by the Market Abuse (Amendment) (EU Exit) Regulations 2019), the Commission Delegated Regulation 2016/1052/EU (as in force in the UK and as amended by the FCA's Technical Standards (Market Abuse Regulation) (EU Exit) Instrument 2019) and in accordance with Chapter 9 of the UK Listing Rules. No repurchases will be made in respect of the Company's American Depositary Receipts.

The Company will make further announcements in due course following any repurchase of shares. There is no guarantee that the First Tranche will be implemented in full or that any shares will be bought back by the Company.
