HSBC HOLDINGS PLC SHARE BUY-BACK
 
HSBC Holdings plc ('HSBC') announces that, as outlined in its announcement on 31 July 2017, 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$2,000,000,000 (the "Buy-back"). The purpose of the Buy-back is to reduce HSBC's outstanding Ordinary Shares.
 
HSBC has entered into an irrevocable, non-discretionary agreement (the 'Agreement') with Credit Suisse Securities (Europe) Limited ('Credit Suisse') to enable the purchase of Ordinary Shares by Credit Suisse, acting as principal, during the period running from 1 August 2017 and ending no later than 31 December 2017 (subject to regulatory approval remaining in place), for an aggregate purchase price of no greater than US$2,000,000,000 and the simultaneous on-sale of such Ordinary Shares by Credit Suisse to HSBC.
 
Any purchases of Ordinary Shares will be carried out on the London Stock Exchange in accordance with certain pre-set parameters and in accordance with (and subject to limits prescribed by) HSBC's general authority to repurchase Ordinary Shares granted by its shareholders at the annual general meeting on 28 April 2017 (the '2017 Authority'), Chapter 12 of the Financial Conduct Authority's Listing Rules and Article 5(1) of Regulation (EU) No 596/2014, the Commission Delegated Regulation (EU) No 2016/1052, the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited, the Hong Kong Codes on Takeovers and Mergers and Share Buy-Backs and applicable US federal securities laws. Ordinary Shares purchased under the Buy-back will be cancelled.
 
The maximum number of Ordinary Shares that may be repurchased under the Buy-back is 1,986,691,641, being the number of Ordinary Shares able to be repurchased under the 2017 Authority.
