The shareholders and the organizing broker comprehensively consider factors such as the shareholders’ personal funding needs to negotiate the lower limit of the transfer price for this inquiry transfer, and the lower limit shall not be less than 70% of the average stock trading price over the last 20 trading days prior to the date of sending the subscription invitation (i.e., March 27, 2026, inclusive). After the inquiry subscription bidding ends, CITIC Securities will cumulatively tally the valid subscriptions and determine the transfer price according to the principles of price priority, quantity priority, and time priority.

The specific method is as follows:

1. If the total number of valid subscriptions for this inquiry transfer exceeds the upper limit of shares for this inquiry transfer, the principles for determining the inquiry transfer price, subscription objects, and the number of allocated shares are as follows (in order of priority based on serial number):

(1) Subscription price priority: cumulative sorting from high to low based on the declared prices;

(2) Subscription quantity priority: for the same declared price, cumulative sorting from high to low based on the subscription quantity;

(3) Time priority of receiving the “Subscription Quotation Form”: for the same declared price and subscription quantity, cumulative sorting based on the time of receipt of the “Subscription Quotation Form” from earliest to latest, with earlier valid subscriptions being prioritized for allocation.

When the total number of all valid subscriptions equals or first exceeds 11,528,931 shares, the cumulative valid subscription’s lowest subscription price will be the inquiry transfer price.

2. If the cumulative valid subscription shares from the inquiry objects total less than 11,528,931 shares, the lowest bid among all valid subscriptions will be determined as the inquiry transfer price.
