On 17 September 2026, China Environmental Technology Holdings Limited released a notification to its registered shareholders confirming that the English and Chinese versions of the company’s latest Interim Report are now accessible on both the corporate website (www.cethl.com/en/Home.aspx) and Hong Kong Exchanges and Clearing’s HKEXnews portal (www.hkexnews.hk).

The board, chaired by Mr Xu Jingping, strongly encourages investors to review the “Website Version” of all current and future corporate communications to support cost efficiency and environmental objectives. Shareholders who have previously requested hard-copy documents will find the printed Interim Report enclosed with the letter.

For investors unable to access electronic copies or who prefer physical documentation, the company provides an opt-in mechanism: • Shareholders may submit the enclosed Request Form to Tricor Investor Services Limited, the Hong Kong branch share registrar, to obtain printed copies of the Interim Report and all subsequent corporate communications at no charge. • Requests can be returned by post using the prepaid mailing label or emailed to 646-ecom@vistra.com.

The notice also reminds shareholders that maintaining an active email address with the registrar is essential. Without a valid email on record, the company will default to sending printed notices of publication and any actionable corporate communications by post until an email address is provided.

Enquiries can be directed to Tricor’s hotline at +852 2980 1333, available Monday to Friday, 9:00 a.m. – 6:00 p.m. (excluding Hong Kong public holidays).
