“In the second quarter, our AI Cloud business continued to deliver robust and healthy revenue growth, supported by our strengthening full-stack AI capabilities and comprehensive end-to-end AI products and solutions.

Apollo Go accelerated global expansion while actively exploring new business models, underscored by our leadership in both left-hand drive and right-hand drive robotaxi markets globally,” said Robin Li, Co-founder and CEO of Baidu. “We remain focused on AI initiatives that offer the greatest long-term value creation potential, where our technology and innovation can make the most meaningful and lasting impact.”

“In Q2, mainly propelled by new AI initiatives, Baidu Core’s non-online marketing revenue exceeded RMB 10 billion for the first time, delivering 34% year-over-year growth and marking a more balanced, diversified mix,” said Haijian He, CFO of Baidu. “We remain committed to our AI investments, focusing on advancing AI transformation across the Mobile Ecosystem, sustaining healthy growth momentum in AI Cloud, and accelerating Apollo Go’s global expansion. While navigating near-term challenges, we believe these strategic priorities will drive significant long-term value.”

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.

Non-GAAP net income attributable to Baidu represents net income attributable to Baidu excluding share-based compensation expenses, amortization and impairment of intangible assets resulting from business combinations, disposal gain or loss, impairment of long-term investments, and fair value gain or loss of long-term investments and exchangeable bonds, adjusted for related income tax effects. 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.
