Kirby McInerney LLP has filed a class action lawsuit against PubMatic, Inc. for investors who acquired securities during the period of February 27, 2025 through August 11, 2025. The lawsuit alleges that PubMatic made false and/or misleading statements about the company's business, operations, and prospects, including a reduction in ad spend from a top DSP partner. Investors who suffered losses have until October 20, 2025, to request lead plaintiff appointment.

Kirby McInerney LLP has recently filed a class action lawsuit against PubMatic, Inc. on behalf of investors who acquired securities between February 27, 2025, and August 11, 2025. The lawsuit alleges that PubMatic made false and/or misleading statements about the company's business, operations, and prospects, including a reduction in ad spend from a top DSP partner.

The complaint filed in this class action lawsuit [NUMBER:1] alleges that throughout the specified period, PubMatic made materially false and/or misleading statements and failed to disclose material adverse facts about the company's business. Specifically, the lawsuit claims that PubMatic failed to disclose that a top DSP buyer was shifting a significant number of clients to a new platform, which evaluated inventory differently, leading to a reduction in ad spend and revenue from this top DSP buyer. These omissions, according to the complaint, made Defendants' positive statements about the company's business, operations, and prospects materially misleading and/or lacking a reasonable basis.

On August 11, 2025, after the market closed, PubMatic released its second quarter 2025 financial report. The report revealed that the company's outlook reflected a reduction in ad spend from one of its top DSP partners. The company's Chief Executive Officer, Rajeev Goel, further stated that a "top DSP buyer" had shifted a significant number of clients to a new platform that evaluated inventory differently, causing significant headwinds. As a result, PubMatic's stock price fell $2.23, or 21.1%, to close at $8.34 per share on August 12, 2025, on unusually heavy trading volume.

Investors who suffered losses during this period are encouraged to contact Bragar Eagel & Squire, P.C., a nationally recognized stockholder rights law firm, to discuss their legal rights. The firm has announced that a class action lawsuit has been filed against PubMatic, Inc. in the United States District Court for the Northern District of California. Investors have until October 20, 2025, to apply to the Court to be appointed as lead plaintiff in the lawsuit.
