Pomerantz Law Firm Initiates Class Action Lawsuit Against PubMatic, Inc. Amid Investment Losses

Investor Alert: Lawsuit Against PubMatic, Inc.

On September 18, 2025, Pomerantz LLP confirmed the filing of a class action lawsuit concerning PubMatic, Inc., identified under the NASDAQ ticker PUBM. This legal action arises from allegations that the company, alongside certain officers and directors, may have participated in fraudulent securities practices detrimental to investors.

Investors who faced losses related to their PubMatic investments are urged to connect with Danielle Peyton from Pomerantz via email or phone to explore their rights and consider joining the lawsuit. By reaching out, potential claimants can express their interest in being appointed as Lead Plaintiffs, thus having a voice in the proceedings. It is vital for interested parties to provide relevant information, such as their contact details and the number of shares purchased. The deadline to act is set for October 20, 2025, allowing investors a limited window to present their claims to the court.

Background of the Class Action

The crux of the current lawsuit revolves around PubMatic’s reported financial outcomes for the second quarter of 2025. During a press release held on August 11, CFO Steven Pantelick indicated a setback in the earnings forecast due to a significant reduction in advertising spend from one of PubMatic's key partners in demand-side platforms (DSP). This predicament was echoed by CEO Rajeev Goel, who disclosed that a prominent DSP buyer had shifted numerous clients to alternative platforms that evaluate ad inventory differently, leading to major challenges for PubMatic.

Consequently, these revelations triggered a drastic reaction in the stock market. On August 12, 2025, PubMatic’s share price plummeted by $2.23, or approximately 21.1%, closing at $8.34. This decline sparked concerns among investors, prompting the law firm to take action.
