Guangzhou Baiyunshan Pharmaceutical Holdings Company Limited (Baiyunshan PH) announced on 22 April 2026 that, pursuant to Rule 2.07A of the Hong Kong Stock Exchange Listing Rules and the paperless listing regime effective since 31 December 2023, the company will shift all future corporate communications to electronic distribution.

The move covers directors’ reports, annual and interim reports (and any summaries), meeting notices, listing documents, circulars and proxy forms. Both English and Chinese versions will be posted on three platforms: 1) the company’s website (www.gybys.com.cn), 2) the company’s third-party disclosure page (www.hmdatalink.com/C14070/en/announcement.php), and 3) HKEXnews (www.hkexnews.hk).

To ensure timely delivery of actionable communications—documents that require shareholder instructions—registered shareholders are encouraged to provide an email address. This can be done by scanning a personalised QR code on the reply form or by returning the signed form to the H-share registrar, Computershare Hong Kong Investor Services Limited, 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong.

Shareholders who do not supply a functional email address will continue to receive printed copies of actionable communications until electronic details are provided. Those preferring hard copies of all corporate communications may submit a written request via the reply form or by emailing Baiyunshan.ecom@computershare.com.hk; such instructions remain valid for one year.

Enquiries can be directed to Computershare Hong Kong Investor Services Limited at +852 2862 8688 during business hours (09:00–18:00, Monday to Friday, excluding Hong Kong public holidays).

The announcement was issued by the Board of Baiyunshan PH.
