On 10 April 2026, CARsgen Therapeutics Holdings Limited issued a reminder confirming the transition to electronic dissemination of all corporate communications. The company will provide printed materials only upon request, aiming to accelerate delivery speed and reduce paper consumption.

Actionable documents—those requiring shareholder instructions—will be emailed individually. If an email address is unavailable or invalid, CARsgen will mail a printed copy together with a reply form to collect the shareholder’s functional email address for future use.

All other corporate communications, including annual and interim reports, meeting notices, circulars and proxy forms, will be posted in both English and Chinese on the company’s website (www.carsgen.com) and on the HKEXnews portal (www.hkexnews.hk).

Shareholders who have not yet supplied an email address are encouraged 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 at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong. In the absence of a valid email address or written objection, shareholders are deemed to have consented to receive the web-based version of all future communications.

Investors preferring hard-copy documents may request printed versions by submitting the reply form or emailing carsgen.ecom@computershare.com.hk. Such requests remain valid for one year unless revoked earlier.

Enquiries should be directed to the share registrar at +852 2862 8688 during business hours, Monday to Friday (excluding Hong Kong public holidays).
