Background of the Allegations

The context for this lawsuit originates from a press release issued on August 11, 2025, wherein PubMatic's Chief Financial Officer, Steven Pantelick, discussed troubling financial forecasts. He disclosed that one of PubMatic’s primary demand-side platform (DSP) partners had significantly reduced its advertising expenditure, which posed substantial challenges for the company. Furthermore, CEO Rajeev Goel indicated that this DSP had transitioned clients to a new platform, affecting how ad inventory was being evaluated.

Following the announcement, PubMatic’s stock price plummeted by $2.23, representing a staggering 21.1% drop, closing at $8.34 per share the day after the news broke. These developments raised suspicions about the company’s operational transparency and adherence to lawful business practices, consistent with the claims central to the class action.
