The Baidu class action lawsuit alleges that defendants throughout the Class Period made false and/or misleading statements and/or failed to disclose that: (i) Baidu had overstated the ability of its AI business to mitigate rapid declines in its legacy online marketing business; (ii) as a result, Baidu’s revenue was reasonably likely to decline; and (iii) as a result of the foregoing, defendants’ positive statements about Baidu’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.
On February 26, 2026, before the market opened, Baidu reported fourth quarter and full year 2025 financial results, allegedly revealing that total revenue fell more than 4% year over year for the fourth quarter to RMB32.74 billion (or $4.68 billion) and fell more than 3% year over year for the full year to RMB129.079 billion (or $18.458 billion). The complaint alleges that Baidu management assured investors its “AI-Powered Business” grew 48% year over year to RMB40 billion for fiscal year 2025, mitigating this transition.

The Baidu class action lawsuit further alleges Baidu disclosed that the Baidu Core AI-powered business fell 8% quarter over quarter to RMB12.5 billion (or $1.86 billion), its year-over-year growth having decelerated from 49% in the first quarter of 2026 to 25%, and its largest component, AI Cloud Infra, having fallen 17% quarter over quarter from RMB8.8 billion to RMB7.3 billion. On this news, the price of Baidu ADS dropped nearly 13%, according to the complaint.
THE LEAD PLAINTIFF PROCESS: The Private Securities Litigation Reform Act of 1995 permits any investor who purchased or acquired Baidu securities, including call options, during the Class Period to seek appointment as lead plaintiff in the Baidu class action lawsuit. A lead plaintiff is generally the movant with the greatest financial interest in the relief sought by the putative class who is also typical and adequate of the putative class. A lead plaintiff acts on behalf of all other class members in directing the Baidu class action lawsuit. The lead plaintiff can select a law firm of its choice to litigate the Baidu class action lawsuit. An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff of the Baidu class action lawsuit.
