China Southern Airlines Company Limited has reiterated that all future corporate communications—including annual and interim reports, meeting notices, circulars and proxy forms—will be distributed exclusively in electronic format via its website (www.csair.com) and the HKEXnews platform (www.hkexnews.hk). Printed copies will no longer be sent automatically.

Registered shareholders who have not yet provided an email address are urged to do so by scanning the personalised QR code on the enclosed reply form or by returning the form to Computershare Hong Kong Investor Services Limited.

Key points: 1. Actionable corporate communications—documents requiring shareholder instructions—will be emailed once a functional address is on file; otherwise, they will be delivered in print until an address is provided. 2. Shareholders preferring hard copies may opt in by submitting the reply form or emailing csair.ecom@computershare.com.hk. This print request remains valid for one year from the date of receipt. 3. Any subsequent update that supplies multiple email addresses will see only the latest address registered.

For enquiries, shareholders can contact csair.ecom@computershare.com.hk. The notice is signed by Joint Company Secretaries Chen Wei Hua and Liu Wei and dated 28 April 2026.
