On 22 September 2026, Ruifeng Power Group Company Limited informed registered shareholders that the English and Chinese versions of its Interim Report 2026 are now accessible on both the company’s website (www.hbsgt.com) and Hong Kong Exchanges and Clearing’s website (www.hkexnews.hk).

To streamline communication and encourage environmentally friendly practices, Ruifeng Power recommends that shareholders review the digital version of the Interim Report and all future corporate communications online. Shareholders who have previously elected to receive printed documents will find the Interim Report enclosed with the notification letter.

The company reiterated that shareholders experiencing difficulties with email notifications or web access may request hard-copy documents at no cost. A reply form is provided for shareholders who wish to: • receive the current and all future corporate communications in printed English, printed Chinese, or both languages; • register or update an email address to obtain electronic notifications of future publications and actionable corporate communications.

Completed reply forms should be returned to the Hong Kong branch share registrar, Tricor Investor Services Limited, by post (17/F, Far East Finance Centre, 16 Harcourt Road, Hong Kong) using the enclosed prepaid mailing label, or by email (is-ecom@vistra.com).

Ruifeng Power emphasized that shareholders who have not supplied a functional email address will continue to receive printed notices and actionable corporate documents until a valid address is provided. For inquiries, shareholders may contact Tricor’s hotline at (+852) 2980 1333 during business hours.

The notification was issued under the authority of Chairman Mr. Meng Lianzhou on behalf of Ruifeng Power Group Company Limited.
