Capitalized terms used but not specifically defined herein shall have the meanings ascribed to them in the U.S. Offer to Purchase. The description of the U.S. Offer in this letter is only a summary and is qualified by the terms and conditions of the U.S. Offer set forth in the U.S. Offer to Purchase and the related materials, including the ADS Letter of Transmittal and the Form of Acceptance.

YOUR PROMPT ACTION IS REQUESTED. WE URGE YOU TO CONTACT YOUR CLIENTS AS PROMPTLY AS POSSIBLE.

Please furnish copies of the following enclosed materials to those of your clients for whose accounts you hold ADSs in your name or in the name of your nominee:

Your attention is directed to the following:.

•

The U.S. Offer commenced on Monday, September 9, 2024 and will expire at 4:00 a.m., New York City time, on Wednesday, October 30, 2024, unless extended.

•

The U.S. Offer is subject to the satisfaction of the Condition described in “The U.S. Offer — Terms and Conditions of the U.S. Offer — Condition to the U.S. Offer” of the U.S. Offer to Purchase. The U.S. Offer is not subject to any financing or minimum tender condition.

•

The Company will not pay any fees or commissions to brokers, dealers, commercial banks, trust companies, or other nominees for soliciting tenders of ADSs or Class A Ordinary Shares pursuant

to the U.S. Offer. However, the Company will, upon request, reimburse brokers, dealers, commercial banks, trust companies, or other nominees for customary mailing and handling expenses incurred by them in forwarding this U.S. Offer to Purchase, the ADS Letter of Transmittal, and other related materials to the beneficial owners of ADSs or Class A Ordinary Shares held by them as a nominee or in a fiduciary capacity.

•

If required by U.S. federal income tax laws, backup withholding at the applicable backup withholding rate will be imposed on any payments made to certain ADS holders pursuant to the U.S. Offer.

•

In order for a book-entry transfer of ADSs held through a broker, dealer, commercial bank, trust company, or other nominee to constitute a valid tender of ADSs in the U.S. Offer, the ADSs must be tendered by the ADS holder’s broker, dealer, commercial bank, trust company, or other nominee before the Latest Acceptance Time. Further, before the Latest Acceptance Time, the Tender Agent must receive (i) a confirmation of a book-entry transfer of the tendered ADSs into the Tender Agent’s account at DTC and (ii) an Agent’s Message.

An ADS holder tendering ADSs in the U.S. Offer will have to pay ADS cancellation fees, but not ADS cash distribution fees, payable to the Depositary.
