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 loss from operations, net loss, net loss attributable to ordinary shareholders, which excludes share-based compensation expenses, amortization of acquired intangible assets and net gain on disposals of subsidiaries. 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.

For more information on these non-GAAP financial measures, please see the table captioned "Reconciliations of GAAP and non-GAAP Results" set forth at the end of this press release.
