On January 30, 2026, the Issuer (as the issuer), the Company (as the guarantor), and the Joint Lead Managers (as the joint lead managers) entered into a subscription agreement. Pursuant to this agreement, the Joint Lead Managers have severally, but not jointly, agreed to subscribe and pay for, or procure subscribers to subscribe and pay for, the Green Notes. Concurrently, the Issuer has agreed to issue the Green Notes to the Joint Lead Managers or as they may direct on the issue date.

The Green Notes will consist of RMB 1.735 billion in 3.40% guaranteed green notes. These will be subscribed for, or procured, severally but not jointly by the Joint Lead Managers and are scheduled to mature in 2029.

The gross proceeds from the proposed Green Notes issuance, before deducting underwriting commissions payable to the Joint Lead Managers and other expenses incurred or to be incurred in connection with the issuance, will amount to RMB 1.735 billion.

The net proceeds from the offering of the Green Notes are intended to be used for refinancing certain medium to long-term offshore debts of the Issuer, the Company, and its subsidiaries falling due within one year. This usage is in accordance with the Enterprise Foreign Debt Verification and Registration Certificate dated July 11, 2025 (Approval No.: Fagaiiban Waizhai 2025[302]).
