The Company used its internal resources for each of the Subscriptions. BASIS OF DETERMINATION OF CONSIDERATION The Board confirmed that the considerations of each of the Subscriptions were determined on the basis of commercial terms negotiated at arm’s length between the Company and each of UBS and ICBC, respectively, having considered (i) the then available surplus cash of the Company for treasury management purpose; (ii) the expected investment return and terms of each of the Subscriptions; and (iii) the prevailing market interest rates and practices.

6 REASONS FOR AND BENEFITS OF THE SUBSCRIPTIONS The Subscriptions were carried out by the Company for treasury management purposes in order to maximize the utilization of its surplus cash received from its business operations, with a view to achieving balanced yields whilst maintaining high liquidity and a low level of risks. Taking into account, among others, the low level of risks and the expected rates of return of the wealth management products, the Company considers that the Subscriptions would provide the Group with better returns than the returns on deposits generally offered by commercial banks and increase the Company’s overall earnings in the long run. The Company has monitored and managed the subscriptions closely and effectively and will continue to do so. Having considered that each of the Subscriptions had been classified as relatively low risk after assessment, and with reference to similar products in the market and their general rates of return, the Board was of the view that the terms of each of the Subscriptions are fair and reasonable and in the best interests of the Company and its Shareholders as a whole. The Group has implemented adequate and appropriate internal control procedures to ensure the Subscriptions would not affect the working capital or the operations of the Group, and that such investments would be conducted on the principle of protecting the interests of the Company and its Shareholders as a whole. GENERAL INFORMATION OF THE PARTIES The Company and Beijing CHJ The Company is a holding company incorporated under the laws of the Cayman Islands and is, through its consolidated subsidiaries and consolidated variable interest entities and their subsidiaries, principally engaged in the design, development, manufacturing, and sales of new energy vehicles and providing other sales and services in the People’s Republic of China. Beijing CHJ is a limited liability company established under the laws of the PRC on April 10, 2015 and a consolidated affiliated entity of the Company. It is principally engaged in technology development in the PRC. ICBC ICBC is a licensed bank in the PRC principally engaged in the provision of banking and related financial services, which is listed on the Stock Exchange (stock code: 01398) and the Shanghai Stock Exchange (stock code: 601398). UBS UBS is a licensed bank incorporated and domiciled in Switzerland and engages in a full range of financial services activities as a bank. UBS is part of UBS Group AG which is a global financial services provider incorporated in Switzerland. UBS Group AG, a company listed on both the SIX Swiss Exchange (SWX: UBS) and the New York Stock Exchange (NYSE: UBS). To the best knowledge, information and belief of the Directors having made all reasonable enquiries, each of ICBC and UBS, and their respective ultimate beneficial owner(s), are third parties independent of the Company and its connected persons.

7 LISTING RULES IMPLICATIONS As all the applicable percentage ratios (as defined under Rule 14.07 of the Listing Rules) in respect of each of the Subscriptions were below 5%, none of the Subscriptions constituted a discloseable transaction of the Company on a standalone basis. Given that the UBS Subscription and the UBS Outstanding Subscriptions were subscribed with UBS and the UBS Outstanding Subscriptions remained outstanding as of the date of the UBS Subscription, pursuant to Rule 14.22 of the Listing Rules, the transactions contemplated under the UBS Subscription shall be aggregated with the UBS Outstanding Subscriptions. Given that the ICBC Subscriptions and the ICBC Outstanding Subscriptions were subscribed with ICBC and relevant ICBC Outstanding Subscriptions remained outstanding as of the dates each of the ICBC Subscriptions, pursuant to Rule 14.22 of the Listing Rules, the transactions contemplated under the each of the ICBC Subscriptions shall be aggregated with the relevant ICBC Outstanding Subscriptions. Pursuant to the Listing Rules, as one or more of the applicable percentage ratios (as defined under Rule 14.07 of the Listing Rules) of the aggregated transaction amounts of each of the UBS Subscription and the UBS Outstanding Subscriptions, and each of the ICBC Subscriptions and the relevant ICBC Outstanding Subscriptions, respectively, exceeded 5% but all of the ratios were below 25%, such transactions constituted discloseable transactions of the Company and shall be subject to the notification and announcement requirements but exempt from the shareholders’ approval requirement under the Listing Rules. The Company should have made an announcement in respect of the each of the Subscriptions as and when such obligations arose. However, as (i) the Company was only listed on the Stock Exchange since August 2021 and is still in the process of familiarizing itself with the requirements under the Listing Rules; and (ii) it is in the Group’s normal course of business operations to utilize its surplus cash reserves to enhance the funds utilization efficiency and bring extra returns, the Company did not realize that the subscriptions of the wealth management products would have implications under Chapter 14 of the Listing Rules and inadvertently overlooked such obligation. The Company would like to emphasize that it has no intention to withhold any information from disclosure to the public as required under the Listing Rules and has always, and will continue to, put great emphasis on the importance of Listing Rules compliance and the risk assessment of its subscriptions for wealth management products. As soon as the Company became aware of its obligation to make an announcement pursuant to Chapter 14 of the Listing Rules, the Company sought relevant professional advice, conducted a comprehensive review of the Group’s subscriptions for wealth management products and published this announcement as soon as practicable. The Company shall continue to enhance its internal control management and strictly control the supervision regarding compliance and risk control matters of its business operations to avoid the re-occurrence of similar incidents. In particular, the Company will (i) strengthen the coordination and reporting arrangements for notifiable transactions within the Group, (ii) designate specific employees to monitor the transaction amounts of any transaction subject to Chapter 14 of the Listing Rules, (iii) enhance the measures within the Group to regularly review and check the size test calculations of transactions, and (iv) continue to work closely with its legal adviser and compliance adviser to ensure compliance with the Listing Rules.
