As resolved at the 2023 annual general meeting of Huaneng Power International, Inc. (the "Company") held on 25 June 2024, the Company has been given a mandate to issue super short-term debentures (in either one or multiple tranches on rolling basis) with a principal amount of up to RMB30 billion (which means that the outstanding principal balance of the super short-term debentures in issue shall not exceed RMB30 billion at any time within the period as prescribed therein) within the period from approval obtained at 2023 annual general meeting to the conclusion of the 2024 annual general meeting.

China Everbright Bank Company Limited and Bank of Ningbo Co., Ltd. acted as the lead underwriters to form the underwriting syndicate for the Debentures, which were placed through bookbuilding and issued in the domestic bond market among banks. The proceeds from the Debentures will be used to supplement the working capital of the Company, adjust debts structure, repay bank loans and the debt due.

The relevant documents in respect of the Debentures are posted on China Money and Shanghai Clearing House at websites of www.chinamoney.com.cn and www.shclearing.com.cn, respectively.
