Lawsuit follows Baidu revenue and share-price declines
The case, Rosewood Funeral Home, Inc. v. Baidu, Inc. et al., was filed on September 14, 2026, in the U.S. District Court for the Southern District of New York under Case No. 26-cv-08012. It covers investors who acquired Baidu securities from November 18, 2025 to August 17, 2026.
The complaint concerns Baidu's financial disclosures during that period. On February 26, 2026, Baidu reported fourth-quarter 2025 revenue of RMB32.74 billion, down more than 4% year over year, while full-year revenue fell more than 3% to RMB129.079 billion. The company said its AI-Powered Business grew 48% year over year to RMB40 billion for fiscal year 2025.
Following that report, Baidu American Depositary Shares fell $7.50, or 5.65%, to close at $125.15 on February 26, 2026, according to the release.
Complaint alleges AI growth did not offset legacy declines
The release says Baidu's August 18, 2026 results showed further deterioration in several areas. General Business revenue fell 4% year over year to RMB25.2 billion. Legacy Business revenue declined 23% to RMB10.4 billion, while total Online Marketing Services revenue fell 19% to RMB13.1 billion.
Baidu Core AI-powered business revenue fell 8% quarter over quarter to RMB12.5 billion. Its year-over-year growth slowed from 49% in the first quarter of 2026 to 25%. AI Cloud Infra, its largest component, fell 17% quarter over quarter from RMB8.8 billion to RMB7.3 billion.
On that news, Baidu ADS fell $13.25, or 12.73%, to close at $90.87 on August 18, 2026. The complaint alleges that defendants overstated the AI business's ability to mitigate declines in legacy online marketing, that revenue was reasonably likely to decline, and that positive statements about Baidu lacked a reasonable basis. These are allegations, and the release states that no class has been certified.
What investors can do before the deadline
Investors who bought Baidu securities during the proposed class period and lost money may be class members. Those seeking to serve as lead plaintiff must file a motion with the court by November 13, 2026.
The lead plaintiff is appointed by the court to represent all class members and direct the class action. Investors do not have to seek that role to potentially share in a recovery. They may take no action and remain absent class members, according to the release.
The Law Offices of Frank R. Cruz says investors may contact the firm through its case page, by email at [email protected], or by calling 310-914-5007. The firm says it works on contingency, with fees and litigation expenses coming only from a recovery, if there is one, and requiring court approval. Investors may retain counsel of their choice.
