BEIJING, China, May 21, 2025 – Baidu, Inc. (NASDAQ: BIDU and HKEX: 9888 (HKD Counter) and 89888 (RMB Counter)) (“Baidu” or the “Company”), a leading AI company with a strong Internet foundation, today announced its unaudited financial results for the first quarter ended March 31, 2025.

“Baidu Core revenue grew 7% year over year in the first quarter, driven by the accelerating momentum of AI Cloud, which surged 42% year over year. The strong performance of our AI Cloud business underscores the growing market recognition of our distinctive strength in providing full-stack AI products and solutions with a highly competitive price-performance advantage. We also achieved a pivotal milestone in our robotaxi business, as Apollo Go expanded internationally by entering Dubai and Abu Dhabi, reinforcing our commitment to bringing safe, comfortable, and affordable autonomous ride-hailing services to global markets,” said Robin Li, Co-founder and CEO of Baidu. “We are confident that our AI-first strategy positions us to remain at the forefront and to capture long-term growth opportunities in the AI era.”

“AI Cloud continued its robust growth in the first quarter, which provides solid support to our overall revenue while we accelerate the AI transformation across our mobile ecosystem,” said Junjie He, Interim CFO of Baidu. “Looking ahead, we are strongly committed to investing in AI to translate our technological strengths into sustainable long-term growth.”

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 (loss) attributable to Baidu, non-GAAP net margin, non-GAAP diluted earnings per ADS, adjusted EBITDA, adjusted EBITDA margin 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.

Non-GAAP operating income represents operating income excluding share-based compensation expenses, and amortization and impairment of intangible assets resulting from business combinations.

Baidu’s share of equity method investments for these non-GAAP reconciling items, amortization and impairment of intangible assets not on the investees’ books, accretion of their redeemable non-controlling interests, and the gain or loss associated with the issuance of shares by the investees at a price higher or lower than the carrying value per share, adjusted for related income tax effects, are also excluded.
