Annex A

Preliminary Non-binding Proposal to Acquire Chindata Group Holdings Limited

June 6, 2023

The Board of Directors

Chindata Group Holdings Limited

No. 47 Laiguangying East Road,

Chaoyang District, Beijing, 100012

The People’s Republic of China

Dear Sirs:

BCPE Bridge Cayman, L.P. and BCPE Stack Holdings, L.P. (collectively, “Bain Shareholders”), are pleased to submit this preliminary non-binding proposal to acquire Chindata Group Holdings Limited (the “Company”) in a going private transaction (the “Acquisition”).

We believe that our proposal provides an attractive opportunity to the Company’s shareholders. Our proposal represents a 33% premium to the closing price on the last trading day prior to the date of this proposal and a premium of 38% to the volume-weighted average price during the last 30 trading days.

1. Purchase Price. The consideration payable for each ordinary share of the Company, par value $0.00001 per share, will be US$4.0 in cash, or US$8.0 in cash for each American Depositary Share of the Company (an “ADS”, representing two Class A ordinary shares of the Company) (in each case other than those ADSs or ordinary shares of the Company that may be rolled over in connection with the proposed Acquisition).

2. Closing Certainty; Funding. We believe that we offer a high degree of closing certainty and are well positioned to negotiate and complete the proposed Acquisition on an expedited basis. We intend to finance the Acquisition with a combination of equity and debt capital and we expect the commitments for the required equity and debt funding, subject to the terms and conditions set forth therein, to be in place when the Definitive Agreements (as defined below) are signed.

3. Due Diligence. We have engaged Kirkland & Ellis as our international legal counsel. We have significant experience in structuring and consummating transactions of this nature and would expect to complete due diligence on an expedited basis. We and our advisors are prepared and ready to engage in the next stage of discussions.

4. Definitive Agreements. We are prepared to promptly negotiate and finalize definitive agreements (the “Definitive Agreements”) providing for the Acquisition and related transactions. These documents will provide for representations, warranties, covenants and conditions that are typical, customary and appropriate for transactions of this type.

5. Process. We expect that the Company’s Board of Directors will establish a special committee comprised of independent and disinterested directors of the Company (the “Special Committee”). Given Bain Shareholders have representatives on the Company’s Board of Directors, we expect that the Special Committee and its advisors will be exclusively authorized to consider and negotiate with us the proposed Acquisition, including the Definitive Agreements, and that no other members of management or any other directors other than the members of the Special Committee will participate in any deliberations and decisions related to the Acquisition unless their involvement is approved by the Special Committee.

In considering our offer, you should be aware that Bain Shareholders do not intend to sell their stake in the Company to any third party. Bain Shareholders in the aggregate beneficially own approximately 42.17% of the total issued and outstanding share capital of the Company, representing 87.39% of the total voting power of the Company.

6. No Binding Commitment. This letter constitutes only a preliminary indication of our interest, and does not constitute any binding commitment with respect to the Acquisition. A binding commitment will result only from the execution of Definitive Agreements, and then will be on terms and conditions provided in such documentation.

In closing, we would like to express our commitment to work together to bring this Acquisition to a successful and timely conclusion. Should you have any questions regarding this proposal, please do not hesitate to contact us. We look forward to hearing from you.
