Event Summary

A class action lawsuit has been filed against PubMatic by Bragar Eagel & Squire on behalf of investors who purchased PubMatic securities between February 27, 2025, and August 11, 2025. The lawsuit alleges that PubMatic made materially false and misleading statements and failed to disclose that a top DSP buyer was shifting clients to a new platform, resulting in a reduction of ad spend and revenue for PubMatic. This information was revealed in PubMatic's second-quarter 2025 financial report on August 11, 2025, causing PubMatic's stock price to fall by 21.1% the following day. Rajeev Goel, CEO, and Steven Pantelick, CFO, of PubMatic, confirmed the reduction in ad spend from a top DSP partner.
