HSBC Holdings plc ("HSBC") announces that, as outlined in its announcement on 4 August 2026, it will commence a share buy-back of HSBC's ordinary shares of US$0.50 each ("Ordinary Shares") for up to a maximum consideration of US$1,000,000,000 (one billion United States dollars) (the "Buy-back"). The purpose of the Buy-back is to reduce HSBC's outstanding Ordinary Shares.

HSBC has entered into non-discretionary buy-back agreements with BNP Paribas Financial Markets SNC ("BNP Paribas") to enable the purchase of Ordinary Shares by BNP Paribas, acting as principal, during the period running from 6 August 2026 and ending no later than 23 October 2026 (subject to regulatory approval remaining in place), for an aggregate purchase price of up to US$1,000,000,000 (one billion United States dollars) and the simultaneous on-sale of such Ordinary Shares by BNP Paribas to HSBC.

BNP Paribas will make trading decisions in relation to the Buy-back independently of HSBC. Any purchases of Ordinary Shares will be carried out on the London Stock Exchange, Aquis Exchange, Cboe Europe Limited (through the BXE and CXE order books) and/or Turquoise (together, the "UK Venues") and/or The Stock Exchange of Hong Kong Limited ("Hong Kong Stock Exchange").

The repurchases on the UK Venues will be implemented as "on Exchange" transactions (as such term is defined in the rules of the London Stock Exchange) and will be "market purchases" for the purposes of the Companies Act 2006. The repurchases on the Hong Kong Stock Exchange will be "off-market" for the purposes of the Companies Act 2006 but will be transactions which occur "on Exchange" for the purposes of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited ("Hong Kong Listing Rules") and which constitute an "on-market share buy-back" for the purposes of the Hong Kong Codes on Takeovers and Mergers and Share Buy-backs ("Hong Kong Buy-back Code").

The repurchases will take place in accordance with certain pre-set parameters and in accordance with (and subject to limits prescribed by) HSBC's authority to make market purchases and off-market purchases of its Ordinary Shares, in each case granted by its shareholders at HSBC's annual general meeting on 8 May 2026 (the "2026 Authority"), Chapter 9 of the Financial Conduct Authority's Listing Rules, Article 5(1) of the Market Abuse Regulation (EU) No 596/2014 (as it forms part of domestic law of the United Kingdom by virtue of the European Union (Withdrawal) Act 2018, as amended (the "Withdrawal Act")), the Commission Delegated Regulation (EU) No 2016/1052 (as it forms part of domestic law of the United Kingdom by virtue of the Withdrawal Act), the Hong Kong Listing Rules, the Hong Kong Buy-back Code and applicable US federal securities laws.

The maximum number of Ordinary Shares that may be repurchased under the Buy-back is 1,718,354,635, being the number of Ordinary Shares able to be repurchased under the 2026 Authority.
