Tong Ren Tang Technologies Co. Ltd. (stock code 01666) has reiterated its decision to adopt a fully electronic distribution model for all future corporate communications, according to a reminder letter dated 28 April 2026.

Key points:

1. Scope of Materials • Documents covered include directors’ reports, annual and interim reports (and any summary versions), notices of meetings, listing documents, circulars and proxy forms. These will be published simultaneously in English and Chinese on the company’s website (www.tongrentangkj.com) and the HKEXnews website (www.hkexnews.hk).

2. Action Required from Non-Registered Shareholders • The company has not yet received functional email addresses from the relevant intermediaries—banks, brokers, custodians, nominees or HKSCC Nominees Limited—through which non-registered shareholders hold their shares. • To receive electronic “Actionable Corporate Communications” (documents requiring shareholder instructions or elections), non-registered shareholders must supply a valid email address to their intermediaries. • Until a valid email address is provided, the company will continue to deliver Actionable Corporate Communications in printed form.

3. Option to Receive Printed Copies • Shareholders preferring hard-copy versions of all future communications can complete and return the enclosed reply form to the Hong Kong share registrar, Computershare Hong Kong Investor Services Limited, or send an email request to tongrentangtech@computershare.com.hk.

4. Contact Information • Enquiries should be directed to the share registrar at +852 2862 8688 during business hours (09:00–18:00, Monday to Friday, excluding Hong Kong public holidays).

The reminder, signed by Chairman Zhang Yi, underscores Tong Ren Tang Technologies’ ongoing shift toward paperless communications in line with Hong Kong Listing Rules and broader sustainability practices.
