We are pleased to advise that the 2019 Interim Report (the "2019 Interim Report") of BOC Hong Kong (Holdings) Limited ("BOCHK") has been prepared in English and Chinese. The English and Chinese versions of the 2019 Interim Report are now available in the "Investor Relations" section of BOCHK's website at www.bochk.comand the website of Hong Kong Exchanges and Clearing Limited ("HKEx") at www.hkexnews.hk.

Those Shareholders who (a) have received a printed copy of the 2019 Interim Report in either the English or Chinese language only and would like to receive a printed copy in the other language; or (b) have chosen (or are deemed to have consented) to access the Corporate Communications (as defined below) posted on BOCHK's website in lieu of receiving printed copies (the "Website Option") and would like to receive a printed copy now; or (c) wish to change their choice of language and means of receipt of all corporate communications issued or to be issued by BOCHK to Shareholders including but not limited to, annual reports and accounts, interim reports, notices of meetings, listing documents, circulars and proxy forms (collectively the "Corporate Communications") of BOCHK, please complete Part A and/or Part B of the Request Form overleaf and return it by post, using the mailing label at the bottom of the Request Form (no postage stamp is necessary if posted in Hong Kong; otherwise please affix an appropriate stamp), or by hand delivery to BOCHK's share registrar, Computershare Hong Kong Investor Services Limited ("BOCHK's Registrar") at 17M Floor, Hopewell Centre, 183 Queen's Road East, Wan Chai, Hong Kong. You may also send a scanned copy of the Request Form duly completed and signed to BOCHK's Registrar via email to [e-mail]. The Request Form may also be downloaded from BOCHK's website at www.bochk.comor HKEx's website at www.hkexnews.hk.

You are entitled at any time by reasonable notice in writing to BOCHK's Registrar to change your choice of language and means of receiving Corporate Communications. Further, if you have chosen (or are deemed to have consented) to access the Corporate Communications posted on BOCHK's website and have any difficulty in receiving or gaining access to the relevant documents, for any reason, BOCHK's Registrar will promptly upon your notice send the printed form of the same to you free of charge.
