DEREGISTRATION OF SECURITIES

Chindata Group Holdings Limited (the “Registrant”) is filing this post-effective amendment (this “Post-Effective Amendment”) to the following registration statements on Form S-8 (collectively, the “Registration Statements”) to deregister all unsold securities originally registered by the Registrant pursuant to the Registration Statements:

On August 11, 2023, the Registrant entered into an Agreement and Plan of Merger (the “Merger Agreement”) with BCPE Chivalry Bidco Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands (“Parent”), and BCPE Chivalry Merger Sub Limited, an exempted company with limited liability incorporated under the laws of the Cayman Islands and a wholly owned subsidiary of Parent (“Merger Sub”). On December 18, 2023 (the “Effective Time”), pursuant to the Merger Agreement, Merger Sub was merged with and into the Registrant (the “Merger”), with the Registrant continuing as the surviving company and a wholly owned subsidiary of Parent. Upon completion of the Merger, the Registrant became a privately-held company.

As a result of the Merger, the Registrant has terminated all offerings of its securities pursuant to the Registration Statements. The Registrant hereby removes from registration, by means of this Post-Effective Amendment, any and all of the securities registered under the Registration Statements that remained unsold as of the Effective Time.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, as amended, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Post-Effective Amendment to the Registration Statements to be signed on its behalf by the undersigned, thereunto duly authorized, in the People’s Republic of China on December 20, 2023.

No other person is required to sign this Post-Effective Amendment in reliance upon Rule 478 under the Securities Act of 1933, as amended.
