Hong Kong Exchanges and Clearing Limited and The Stock Exchange of Hong Kong Limited disclaim responsibility for the contents of the announcement referenced below. China High Speed Transmission Equipment Group Co., Ltd. (658) (CHS) has released a voluntary announcement addressing statements and allegations from Fullshare Holdings Limited (Fullshare), alongside updates on the ongoing criminal investigation in the PRC.

CHS reiterates that it received notification from the Nanjing Public Security Bureau, Jiangning Branch, indicating a formal investigation into a criminal case involving suspected embezzlement and misappropriation of funds and assets of certain CHS subsidiaries. According to CHS, the investigation remains ongoing, and no communication from the relevant authorities has supported Fullshare’s recent public assertion regarding purportedly confirmed investigation results. CHS also notes that interim findings in criminal investigations are considered state secrets under PRC law and are not shared with unauthorized parties.

In the announcement, CHS explains that it chose Jinhu County, Jiangsu, as the venue for general meetings due to its accessibility and its business presence there. The same venue was previously used for CHS’s Annual General Meeting in June 2025, at which Fullshare exercised its voting rights.

CHS further references its earlier disclosures regarding potential amendments to the NHS Articles, indicating that explanations for these amendments had already been provided in previous announcements. CHS concludes by advising shareholders and investors to remain cautious when dealing in its securities and states that any material developments will be disclosed based on official and verifiable information, in line with applicable laws and regulations.
