RECKITT BENCKISER GROUP PLC

2026 SHARE BUYBACK PROGRAMME

Reckitt Benckiser Group plc ("Reckitt" or the "Company") announces that in connection with its intention to commence its latest share buyback programme of up to £500 million (the "Programme") over the next 12 months, which was announced on 29 July 2026, the Programme will commence on 5 August 2026. The purpose of the new share buy-back programme is to increase returns to shareholders and to reduce the share capital of Reckitt.

In accordance with the Company's general authority to make market purchases of existing ordinary shares of 10 5/12 pence each in the share capital of the Company (the "Ordinary Shares") as granted by shareholders at the Company's Annual General Meeting on 21 May 2026, the Company will purchase no more than 64,490,000 Ordinary Shares. The first tranche of the Programme will commence on 5 August 2026 and is expected to end no later than 11 December 2026. The first tranche will return up to £150 million of capital to shareholders. All shares repurchased under the first tranche will be held in treasury.

Reckitt announces that it has entered into an agreement with Citigroup Global Markets Limited ("Citi") under which it has issued an instruction to Citi to manage the first tranche of the Programme. Citi will, acting as riskless principal, purchase Ordinary Shares for an aggregate purchase price of no greater than £150 million and will simultaneously sell such Ordinary Shares on to the Company.

Any purchase of Ordinary Shares in relation to this announcement will be carried out on the London Stock Exchange and Multilateral Trading Facilities, as defined by the Directive 2014/65/EU on markets in financial instruments (including the delegated and implementing acts adopted under it) 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, and executed in accordance with the UK Listing Rules and Reckitt's general authority to make market purchases of Ordinary Shares. The shares will be purchased in accordance with the price and volume conditions set out in the Commission Delegated Regulation (EU) 2016/1052 of 8 March 2016 supplementing Regulation (EU) No 596/2014 of the European Parliament and of the Council with regard to regulatory technical standards for the conditions applicable to buyback programmes and stabilisation measures 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.

Following the recent amendments to UKLR 9.6.6, the Company will announce purchases made under the Programme on a weekly basis rather than through daily announcements. Each announcement will contain aggregate and transaction-level details of purchases made during the relevant reporting period.

For the avoidance of doubt, no repurchases will be made in respect of the Company's American Depository Receipts.

Any further tranches of the Programme, which may be conducted after completion of this first tranche, will be announced in due course.

This announcement does not constitute, or form part of, an offer or any solicitation of an offer for securities in any jurisdiction.
