Investing.com -- Baidu shares slid in U.S. premarket trading Tuesday after the Chinese search and AI giant reported second-quarter earnings and revenue that missed analyst expectations.

The company reported second-quarter earnings per share of RMB7.22, missing the analyst estimate of RMB9.84. Revenue came in at RMB31.33 billion, down 4% year-over-year, and also below the RMB31.95 billion consensus estimate.

Shares in the Chinese internet giant fell about 3% in the U.S. pre-open trade by 05:08 ET.

AI Cloud Infrastructure revenue rose 50% year-over-year to RMB7.3 billion, with GPU Cloud revenue within that segment surging 283% year-over-year, accelerating from 184% growth in the prior quarter.

AI Applications revenue rose 3% to RMB2.5 billion, while revenue from AI-native marketing services was roughly flat year-over-year at RMB2.6 billion.

"With AI-powered Business now firmly established as the core of Baidu, we are strengthening the foundations for our next phase of AI-driven growth. AI Cloud Infra sustained strong momentum this quarter, with GPU Cloud growth accelerating further off an already high base," said Robin Li, co-founder and CEO of Baidu.

"While our online marketing business remains under pressure, the growing momentum in our core AI-powered Business reaffirms Baidu’s transition from an internet-centric company to an AI-first company, and strengthens our confidence in our long-term growth potential," he added.
