Non-GAAP Financial Measures

To supplement Baidu’s consolidated financial results presented in accordance with GAAP, Baidu uses the following non-GAAP financial measures: non-GAAP operating income, non-GAAP operating margin, non-GAAP net income attributable to Baidu, non-GAAP net margin, non-GAAP diluted earnings per ADS, adjusted EBITDA, adjusted EBITDA margin, adjusted long-term investments and free cash flow. 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 GAAP.

Baidu believes that these non-GAAP financial measures provide meaningful supplemental information regarding its performance and liquidity by excluding certain items that may not be indicative of its recurring core business operating results, such as operating performance excluding non-cash charges or non-operating in nature. The Company believes that both management and investors benefit from referring to these non-GAAP financial measures in assessing its performance and when planning and forecasting future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to Baidu’s historical performance and liquidity. The Company believes these non-GAAP financial measures are useful to investors in allowing for greater transparency with respect to supplemental information used by management in its financial and operational decision making. A limitation of using these non-GAAP financial measures is that these non-GAAP measures exclude certain items that have been and will continue to be for the foreseeable future a significant component in the Company’s results of operations. These non-GAAP financial measures presented here may not be comparable to similarly titled measures presented by other companies. Other companies may calculate similarly titled measures differently, limiting their usefulness as comparative measures to the Company’s data.
