Important reminders regarding the issuance process, subscription, payment, and handling of investor defaults are as follows:

1. The priority allocation date for original shareholders and the online subscription date for this convertible bond issuance are both June 26, 2026 (T day). The subscription period is T day from 9:15-11:30 and 13:00-15:00. When participating in priority allocation on June 26, 2026 (T day), original shareholders must pay sufficient funds for the convertible bonds within their allocated quota. Original shareholders and general public investors do not need to pay subscription funds when participating in the online subscription for the remaining portion after priority allocation.

2. Investors should determine their subscription amount reasonably based on industry regulatory requirements and their respective asset or capital scale, and should not subscribe beyond their asset or capital scale. If the sponsor (lead underwriter) discovers that an investor has violated industry regulatory requirements by subscribing beyond their respective asset or capital scale, it has the right to deem the investor's subscription invalid. Investors should express their subscription intentions independently and should not entrust securities companies to subscribe on their behalf in a general manner.

3. Investors can only use one securities account to participate in the online subscription of convertible bonds. If the same investor participates in the subscription of the same convertible bond using multiple securities accounts, or uses the same securities account to subscribe for the same convertible bond multiple times, only the first subscription will be considered a valid subscription, and all other subscriptions will be deemed invalid. Once confirmed by the SZSE trading system, subscriptions cannot be withdrawn.
