Investors of PubMatic, Inc. Urged to Join Securities Fraud Lawsuit

On October 7, 2025, the Rosen Law Firm, a renowned global law firm advocating for investor rights, announced significant updates regarding the ongoing securities fraud lawsuit against PubMatic, Inc. (NASDAQ: PUBM). This marks a crucial opportunity for investors who purchased PubMatic securities within the defined Class Period—from February 27, 2025, to August 11, 2025—to take action before the lead plaintiff deadline of October 20, 2025.

Important Information for Investors

What is the Class Action about?

The lawsuit presents serious allegations that during the Class Period, PubMatic executives made misleading statements about the Company’s performance and growth prospects. It is claimed that a major demand-side platform (DSP) buyer unexpectedly shifted many of its clients to a competing platform. This transition assessed inventory in a decidedly different manner, leading to a concerning decrease in advertising expenditure and revenue from that key DSP client for PubMatic.

The lawsuit argues that these revelations significantly misrepresented the true state of PubMatic’s business operations, leading to investor losses once the factual details became public. Consequently, investors endured monetary damages when the truth was finally disclosed to the market.
