Use of Non-GAAP Financial Measures

To supplement Chindata Group’s consolidated financial results presented in accordance with U.S. GAAP, Chindata Group uses adjusted EBITDA and adjusted EBITDA margin as non-GAAP financial measure. The presentation of the non-GAAP financial measure is not intended to be considered in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP.

The Company believes that these non-GAAP financial measures provide useful information to investors and others in understanding and evaluating its operating results as they do not include all items that impact its net loss or income for the period, and are presented to enhance investors’ overall understanding of the Company’s financial performance. A limitation of using the non-GAAP financial measure is that the non-GAAP measure exclude certain items that have been and will continue to be for the foreseeable future a significant component in the Company’s results of operations. The non-GAAP financial measure presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to the Company’s data.
