Faruqi & Faruqi Investigates Claims Against PubMatic for Misleading Statements

Faruqi & Faruqi, LLP is investigating potential claims against PubMatic, Inc. 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 a reduction in ad spend and revenue from a top DSP buyer. PubMatic's stock price fell 21.1% after the company revealed the inventory valuation change. Investors who bought PubMatic stock between June 9, 2022 and August 11, 2025 may be eligible to seek the role of lead plaintiff in a federal securities class action.

New York, Aug. 21, 2025 - PubMatic, Inc. (NASDAQ: PUBM) is facing class action lawsuits alleging securities violations. The lawsuits, filed in the United States District Court for the Northern District of California, allege that the company and its executives made false and/or misleading statements and failed to disclose a significant reduction in ad spend and revenue from a top DSP buyer.

Class Action Details

The lawsuits, filed by Bragar Eagel & Squire, P.C. and Glancy Prongay & Murray LLP, represent investors who purchased PubMatic securities between February 27, 2025 and August 11, 2025 [1]. The complaints allege that during this period, PubMatic failed to disclose that a top DSP buyer was shifting a significant number of clients to a new platform, which evaluated inventory differently. This change led to a reduction in ad spend and revenue from this top DSP buyer, resulting in misleading statements about the company's business, operations, and prospects.

Stock Price Impact

On August 11, 2025, after the market closed, PubMatic released its second quarter 2025 financial report, revealing the reduction in ad spend from a top DSP partner. The company'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 [2].
