If you suffered losses exceeding $50,000 in PubMatic between February 27, 2025 and August 11, 2025 and would like to discuss your legal rights, call Faruqi & Faruqi partner Josh Wilson directly at 877-247-4292 or 212-983-9330 (Ext. 1310).

Faruqi & Faruqi, LLP, a leading national securities law firm, is investigating potential claims against PubMatic, Inc. (“PubMatic” or the “Company”) (NASDAQ: PUBM) and reminds investors of the October 20, 2025 deadline to seek the role of lead plaintiff in a federal securities class action that has been filed against the Company.

Faruqi & Faruqi is a leading national securities law firm with offices in New York, Pennsylvania, California and Georgia. The firm has recovered hundreds of millions of dollars for investors since its founding in 1995. See www.faruqilaw.com.

As detailed below, the complaint alleges that the Company and its executives violated federal securities laws by making false and/or misleading statements and/or failing to disclose that: (1) that a top DSP buyer was shifting a significant number of clients to a new platform which evaluated inventory differently; (2) that, as a result, PubMatic was seeing a reduction in ad spend and revenue from this top DSP buyer; and (3) that, as a result of the foregoing, Defendants’ positive statements about the Company’s business, operations, and prospects were materially misleading and/or lacked a reasonable basis.

On August 11, 2025, after the market closed, PubMatic released its second quarter 2025 financial report. In its report, PubMatic’s Chief Financial Officer, Steven Pantelick, revealed that the Company’s outlook reflects “a reduction in ad spend from one of [its] top DSP partners.” The Company’s Chief Executive Officer, Rajeev Goel, further revealed that a “top DSP buyer” had “shifted a significant number of clients to a new platform that evaluates inventory differently” causing significant headwinds. Goel stated, in response to the inventory valuation change, the Company would “need to do a better job . . . to prioritize across all the hundreds of billions of daily ad impressions that we have, which subset of those impressions that we send to this DSP.”

On this news, 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.

The court-appointed lead plaintiff is the investor with the largest financial interest in the relief sought by the class who is adequate and typical of class members who directs and oversees the litigation on behalf of the putative class. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member. Your ability to share in any recovery is not affected by the decision to serve as a lead plaintiff or not. 

Faruqi & Faruqi, LLP also encourages anyone with information regarding PubMatic’s conduct to contact the firm, including whistleblowers, former employees, shareholders and others.
