ISP Holdings Limited announced on 17 September 2026 that its 2026 Interim Report has been published on the company’s website (www.isp-hk.com.hk) and on the HKEX disclosure platform (www.hkexnews.hk). Printed copies have been dispatched only to shareholders who previously elected to receive hard-copy materials; all other investors may request a complimentary printed version from the Hong Kong share registrar, Computershare Hong Kong Investor Services Limited, at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wanchai, Hong Kong, or via email at investor@isp-hk.com.hk.

Pursuant to Listing Rule 2.07A, ISP Holdings has now adopted electronic delivery as the default method for all future corporate communications. Both English and Chinese versions of subsequent documents—including annual and interim reports, meeting notices, circulars and proxy forms—will be accessible solely through the company and HKEX websites unless shareholders specifically request printed copies.

Non-registered shareholders are urged to supply a functional email address to their respective banks, brokers, custodians or other CCASS intermediaries to ensure timely receipt of electronic notifications. Investors who do not provide a valid email address may not receive publication alerts and will need to monitor the company and HKEX websites independently.

Shareholders retain the right to change their preferred language or method of receipt at any time by submitting the designated reply form to Computershare or by emailing investor@isp-hk.com.hk. Telephone enquiries can be directed to the dedicated hotline on +852 2635 8290 during normal business hours (09:00–18:00, Monday to Friday, excluding Hong Kong public holidays).

The notice was issued under the authority of the Board and signed by Chairman Kingston Chu Chun Ho.
