Pursuant to the new regulations on overseas listing filing for domestic enterprises that took effect on March 31, 2023, when an enterprise chooses to list via H shares in Hong Kong, the former "small route letter" has become history. Enterprises can directly submit their prospectus for overseas listing, and the "general route letter" will be replaced by the "Filing Notice". Recently, the Department of International Cooperation of the China Securities Regulatory Commission (CSRC) issued the Filing Notice for Overseas Issuance and Listing of Horizon Robotics (Guohe Han [2024] No. 1640). Horizon Robotics: We have received the filing materials for overseas issuance and listing submitted by your company through its domestic operating entity, Beijing Horizon Information Technology Co., Ltd. Pursuant to the Securities Law of the People's Republic of China, the Interim Measures for the Administration of Overseas Issuance and Listing of Securities by Domestic Enterprises and other regulations, we hereby notify you of the filing matters as follows: 1. Your company intends to issue no more than 1,153,546,800 shares of overseas listed common shares and list on The Stock Exchange of Hong Kong Limited (HKEX). 2. From the date of issuance of this Filing Notice until the completion of this overseas issuance and listing, if any major event occurs to your company, you shall report it through the CSRC Filing Management Information System in accordance with the relevant regulations on overseas issuance and listing of domestic enterprises. 3. Within 15 working days after the completion of your overseas issuance and listing, you shall report the issuance and listing situation through the CSRC Filing Management Information System. Your company shall strictly comply with the relevant laws, regulations and rules at home and abroad during the overseas issuance and listing process. 4. If your company fails to complete the overseas issuance and listing within 12 months from the date of issuance of this Filing Notice and intends to continue the process, you shall update the filing materials. This Filing Notice only confirms the filing information for the company's overseas issuance and listing, and does not indicate that the CSRC makes a substantive judgment or guarantee on the investment value of the company's securities or the returns of investors, nor does it indicate that the CSRC guarantees or confirms the truthfulness, accuracy and completeness of the company's filing materials. According to the HKEX Listing Rules, enterprises are required to submit the "Filing Notice" at least 4 business days before the hearing approval date, which means that Horizon Robotics has met the pre-requirements for the Hong Kong listing hearing, and will hold the listing hearing at HKEX soon.
