About Non-GAAP Financial Measures

To supplement the Company's unaudited consolidated financial results presented in accordance with United States Generally Accepted Accounting Principles (“GAAP”), the Company has provided non-GAAP information related to income from operations, net income, net income attributable to ordinary shareholders of Tuniu Corporation, which excludes share-based compensation expenses and amortization of acquired intangible assets. The presentation of this 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 U.S. GAAP. We believe that the non-GAAP financial measures used in this press release are useful for understanding and assessing underlying business performance and operating trends, and management and investors benefit from referring to these non-GAAP financial measures in assessing our financial performance and when planning and forecasting future periods.

This non-GAAP financial measure is not defined under U.S. GAAP and is not presented in accordance with U.S. GAAP. The non-GAAP financial measure has limitations as an analytical tool. Further, this non-GAAP measure may differ from the non-GAAP information used by other companies, including peer companies, and therefore its comparability may be limited. The Company compensates for these limitations by reconciling the non-GAAP financial measure to the nearest U.S. GAAP performance measure, all of which should be considered when evaluating performance. Tuniu encourages investors and others to review its financial information in its entirety and not rely on a single financial measure.
