On 17 April 2026, China Boton Group Company Limited announced the release of four key documents—its 2025 Annual Report, an accompanying circular, the notice of the 2026 Annual General Meeting (AGM) and the corresponding proxy form.

English and Chinese versions of all materials are now accessible on both the company’s website (www.boton.com.hk) and the Hong Kong Stock Exchange website (www.hkexnews.hk). Printed copies are being distributed in line with each shareholder’s previously registered preference and remain available free of charge upon request.

Shareholders may alter their future communication format—choosing between website access and hard copies—by submitting a written notice or an email (3318-ecom@vistra.com) to the company’s Hong Kong branch registrar, Tricor Investor Services Limited. Tricor can also be contacted by phone at (852) 2980 1333 during business hours.

The change request form enclosed with the notification allows shareholders to: 1. Switch to electronic delivery with email alerts; 2. Receive printed English versions only; 3. Receive printed Chinese versions only; or 4. Receive both printed English and Chinese versions.

These instructions will stand for all subsequent corporate communications—defined to include financial statements, interim reports, meeting notices, circulars and proxy forms—unless amended by shareholders through reasonable prior written notice.
