Use of Non-GAAP Financial Measures

The unaudited condensed consolidated financial information is prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”). In evaluating our business, we consider and use certain non-GAAP measures, Non-GAAP gross profit, Non-GAAP gross margin, Non-GAAP operating (loss) profit, Non-GAAP operating (loss) profit margin, Non-GAAP EBITDA, Non-GAAP EBITDA margin, Non-GAAP net (loss) profit and Non-GAAP net (loss) profit margin, as supplemental measures to review and assess our 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. We define Non-GAAP gross profit as gross profit excluding share-based compensation allocated in the cost of revenues, and we define Non-GAAP gross margin as Non-GAAP gross profit as a percentage of revenues. We define Non-GAAP operating (loss) profit as operating loss excluding share-based compensation, impairment of long-lived assets and amortization of intangible assets and we define Non-GAAP operating (loss) profit margin as Non-GAAP operating (loss) profit as a percentage of revenues. We define Non-GAAP net (loss) profit as net loss excluding share-based compensation, foreign exchange (gain) loss and impairment of long-lived assets, and we define Non-GAAP net (loss) profit margin as Non-GAAP net (loss) profit as a percentage of revenues. We define Non-GAAP EBITDA as Non-GAAP net (loss) profit excluding interest income, interest expense, income tax expense (benefit) and depreciation and amortization, and we define Non-GAAP EBITDA margin as Non-GAAP EBITDA as a percentage of revenues. We present these non-GAAP financial measures because they are used by our management to evaluate our operating performance and formulate business plans. We also believe that the use of these non-GAAP measures facilitates investors’ assessment of our operating performance.

These non-GAAP financial measures are not defined under U.S. GAAP and are not presented in accordance with U.S. GAAP. These non-GAAP financial measures have limitations as analytical tools. One of the key limitations of using these non-GAAP financial measures is that they do not reflect all items of income and expense that affect our operations. Further, these non-GAAP measures may differ from the non-GAAP information used by other companies, including peer companies, and therefore their comparability may be limited.

We compensate for these limitations by reconciling these non-GAAP financial measures to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating our performance. We encourage you to review our financial information in its entirety and not rely on a single financial measure.
