USE OF NON-GAAP FINANCIAL MEASURES

In evaluating its business, BEST considers and uses non-GAAP measures, such as non-GAAP net loss, non-GAAP net loss margin, adjusted EBITDA, adjusted EBITDA margin, and EBITDA, as supplemental measures in the evaluation of the Company’s operating results and in the Company’s financial and operational decision-making. The Company believes these non-GAAP financial measures that help identify underlying trends in the Company’s business that could otherwise be distorted by the effect of the expenses and gains that the Company includes in loss from operations and net loss. The Company believes that these non-GAAP financial measures provide useful information about its operating results, enhance the overall understanding of its past performance and future prospects and allow for greater visibility with respect to key metrics used by the Company’s management in its financial and operational decision-making.

In addition, the Company’s calculation of the non-GAAP financial measures may be different from the calculation used by other companies, and therefore comparability may be limited.
