What the lawsuit alleges
According to the DJS Law Group, the complaint accuses Baidu of violating Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5, which was promulgated under the act by the U.S. Securities and Exchange Commission.
The core allegation concerns the company's shift from its older business to artificial intelligence. Per the complaint, as described by the law firm, Baidu "made false and misleading statements to the market." The complaint says the company was incapable of replacing revenue lost by its legacy advertising business with new revenue in its AI business, despite its statements to the contrary. On that basis, the complaint holds that Baidu's public statements were false and materially misleading throughout the class period.
These are allegations made in a complaint and described in a law firm's press release. The source does not report any court finding, and it does not include a response from Baidu.
