On 31 March 2026, Wai Chun Bio-Technology Limited announced that its Interim Report for the 2025/26 financial year has been published in both English and Chinese on the company’s website (www.0660.hk) and on the HKEXnews portal (www.hkexnews.hk).

Registered shareholders who have not yet provided an email address—or whose email address on record is invalid—may now opt to receive electronic notifications rather than printed letters. To activate this option, shareholders should complete and return the reply form to Union Registrars Limited via email (660-corpcomm@unionregistrars.com.hk), post, or in person at Suites 3301-04, 33/F, Two Chinachem Exchange Square, 338 King’s Road, North Point, Hong Kong. Mail posted within Hong Kong can use the pre-printed label without postage.

Printed copies of corporate communications remain available free of charge upon written request. Shareholders encountering difficulty accessing documents online can also request hard copies at any time using the same contact details.

For further enquiries, shareholders may contact Union Registrars Limited on +852 2849 3399 during business hours (09:00–17:00, Monday to Friday, excluding Hong Kong public holidays).
