On 28 April 2026, Kasen International Holdings Limited issued a reminder to registered shareholders regarding its transition to electronic dissemination of corporate communications.

Both English and Chinese versions of future documents—including annual and interim reports, meeting notices, circulars and proxy forms—will be posted on the company’s website (www.irasia.com/listco/hk/kasen/index.htm) and on HKEXnews (www.hkexnews.hk) in place of printed copies.

Shareholders who have not supplied a functional 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. Without a valid email address: • Shareholders will not receive notifications of new publications. • They must proactively visit the above websites to access materials. • Actionable corporate communications will continue to be sent in hard copy.

Investors preferring physical documents can request printed versions via the reply form or by emailing kasen.ecom@computershare.com.hk. This instruction will remain effective for one year from the date of receipt.

Enquiries should be directed to the share registrar at kasen.ecom@computershare.com.hk. The reminder was authorised by Chairman Zhu Zhangjin on behalf of the board.
