HSBC HOLDINGS PLC

23 January 2024

Transaction in own shares

HSBC Holdings plc ("HSBC" or the "Company") announces that it has purchased for cancellation the following number of its ordinary shares of US$0.50 from Morgan Stanley & Co. International plc ("Morgan Stanley") as part of its buy-back announced on 31 October 2023.

UK Venues

Date of purchase:	23 January 2024
Number of ordinary shares of US$0.50 each purchased:	2,746,241
Highest price paid per share:	£6.0200
Lowest price paid per share:	£5.9460
Volume weighted average price paid per share:	£5.9863

All repurchases on the London Stock Exchange, Aquis Exchange, Cboe Europe Limited (through the BXE and CXE order books) and/or Turquoise ("UK Venues") are implemented as "on Exchange" transactions (as such term is defined in the rules of the London Stock Exchange) and as "market purchases" for the purposes of the Companies Act 2006.

Hong Kong Stock Exchange

Date of purchase:	23 January 2024
Number of ordinary shares of US$0.50 each purchased:	2,490,800
Highest price paid per share:	HK$59.6500
Lowest price paid per share:	HK$59.0500
Volume weighted average price paid per share:	HK$59.3382

All repurchases on The Stock Exchange of Hong Kong Limited ("Hong Kong Stock Exchange") are "off market" for the purposes of the Companies Act 2006 but are transactions which occur "on Exchange" for the purposes of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited and which constitute an "on-market share buy-back" for the purposes of the Codes on Takeovers and Mergers and Share Buy-backs.

Since the commencement of the buy-back announced on 31 October 2023, the Company has repurchased 338,048,369 ordinary shares for a total consideration of approximately US$2,601.7m.

Following the cancellation of the shares repurchased on the UK Venues, the Company's issued ordinary share capital will consist of 19,149,244,760 ordinary shares with voting rights. There are no ordinary shares held in treasury. Cancellation of the shares repurchased today on the Hong Kong Stock Exchange takes longer than those repurchased on the UK Venues and a further announcement of total voting rights will be made once those shares have been cancelled.

The above figure of 19,149,244,760 may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the Company as required under the Disclosure Guidance and Transparency Rules in the UK and/or the Securities and Future Ordinance in Hong Kong.

In accordance with Article 5(1)(b) 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), a full breakdown of the individual trades made by Morgan Stanley on behalf of the Company is available via the link below.
