Use of Non-GAAP Financial Measures

The Company also uses certain non-GAAP financial measures in evaluating its business. For example, the Company uses non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net margin, non-GAAP net income (loss) attributable to ordinary shareholders of Baozun and diluted non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS, as supplemental measures to review and assess its financial and operating performance. The presentation of these non-GAAP financial measures is not intended to be considered in isolation, or as a substitute for the financial information prepared and presented in accordance with U.S. GAAP.

The Company defines non-GAAP income (loss) from operations as income (loss) from operations excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisition, acquisition-related expenses, impairment of goodwill and cancelation fees of repurchased. The Company defines non-GAAP net income (loss) as net (loss) income excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisition, acquisition-related expenses, impairment of goodwill and investments, other-than-temporary impairment of equity method investments, cancellation fees of repurchased ADSs, fair value loss on financial instruments, loss (gain) on disposal/acquisition of subsidiaries, and unrealized investment loss (gain). The Company defines non-GAAP net income (loss) attributable to ordinary shareholders of Baozun as net income (loss) attributable to ordinary shareholders of Baozun excluding the impact of share-based compensation expenses, amortization of intangible assets resulting from business acquisition, acquisition-related expenses, impairment of goodwill and investments, other-than-temporary impairment of equity method investments, cancellation fees of repurchased ADSs, fair value loss on financial instruments, loss (gain) on disposal/acquisition of subsidiaries, and unrealized investment loss (gain). The Company defines diluted non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS as non-GAAP net income (loss) attributable to ordinary shareholders of Baozun divided by weighted average number of shares used in calculating net income (loss) per ordinary share multiplied by three.

The Company presents the non-GAAP financial measures because they are used by the Company’s management to evaluate the Company’s financial and operating performance and formulate business plans. Non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net income (loss) attributable to ordinary shareholders of Baozun and Non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS reflect the Company’s ongoing business operations in a manner that allows more meaningful period-to-period comparisons. The Company believes that the use of the non-GAAP financial measures facilitates investors to understand and evaluate the Company’s current operating performance and future pros pects in the same manner as management does, if they so choose. The Company also believes that the non-GAAP financial measures provide useful information to both management and investors by excluding certain expenses, gain/loss and other items that are not expected to result in future cash payments or that are non-recurring in nature or may not be indicative of the Company’s core operating results and business outlook.

The non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. The non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using non-GAAP income (loss) from operations, non-GAAP net income (loss), non-GAAP net income (loss) attributable to ordinary shareholders of Baozun, and non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS is that they do not reflect all items of income and expense that affect the Company’s operations. Further, the non-GAAP measures may differ from the non-GAAP measures used by other companies, including peer companies, potentially limiting the comparability of their financial results to the Company’s. In light of the foregoing limitations, the non-GAAP income (loss) from operations, non-GAAP operating margin, non-GAAP net income (loss), non-GAAP net margin, non-GAAP net income (loss) attributable to ordinary shareholders of Baozun and non-GAAP net income (loss) attributable to ordinary shareholders of Baozun per ADS for the period should not be considered in isolation from or as an alternative to income (loss) from operations, operating margin, net income (loss), net margin, net income (loss) attributable to ordinary shareholders of Baozun and net income (loss) attributable to ordinary shareholders of Baozun per ADS, or other financial measures prepared in accordance with U.S. GAAP.

The Company compensates for these limitations by reconciling the non-GAAP financial measures to the nearest U.S. GAAP performance measures, which should be considered when evaluating the Company’s performance. The Company encourages you to review the Company’s financial information in its entirety and not rely on a single financial measure. For reconciliations of these non-GAAP financial measures to the most directly comparable GAAP financial measures, please see the section of the accompanying tables titled, “Reconciliations of GAAP and Non-GAAP Results.”
