ITEM 1. LEGAL PROCEEDINGS

On September 8, 2025, we filed a civil action against Google LLC (“Google”) in the U.S. District Court for the Eastern District of Virginia seeking injunctive relief and damages for monopolistic and anticompetitive behavior in the publisher ad server and ad exchange markets for open-web display advertising. Given the nature of the case, including that the proceedings are in their early stages, we are unable to predict the ultimate outcome of the case.

From time to time, we may become involved in legal or regulatory proceedings, lawsuits and other claims arising in the ordinary course of our business. In view of the inherent difficulty of predicting the outcome of such matters, we cannot state what the eventual outcome of such matters will be. However, based on our knowledge, we are not presently a party to any legal proceedings that, in the opinion of our management, would individually or taken together have a material adverse effect on our business, operating results, financial condition, or cash flows. Regardless of outcome, litigation can have an adverse impact on us due to defense and settlement costs, diversion of management resources, negative publicity and reputational harm, and other factors. For additional information, see Note 8, “Commitments and Contingencies,” to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.
