In relation to the Registered Direct Offering, each of the Purchasers and Mr. Xiaofeng Ma, the chairman and CEO of the Company, together with its affiliated entities, namely Able Knight Development Limited and Joingear Limited, entered into a lock-up agreement (the “Lock-Up Agreement”, the substantial form of which is attached hereto as Exhibit 99.2) with the Company, pursuant to which, each of them have agreed that, from the closing date of the Registered Direct Offering until April 30, 2026, it shall not transfer any Common Shares, ADSs or other securities of the Company beneficially owned, held or hereafter acquired by him or it, subject to customary exceptions. The Lock-Up Agreements will come into effect upon the closing of the Registered Direct Offering.

Subject to the approval by the board of directors of the Company, the net proceeds from the Registered Direct Offering will be used for the general working capital of the Company.
