Should l Buy RMBS?
In a regulatory filing, Rambus said: "Commencing in the first quarter of 2026, we have been responding to a U.S. federal grand jury subpoena in connection with a criminal investigation being conducted by the U.S. Department of Justice, Antitrust Division. Litigation and other proceedings, such as we experienced in our history and the current DOJ matter, can be lengthy, expensive and disruptive to our operations, and results cannot be predicted with certainty. Any settlement of a matter or adverse decision could include monetary fines or damages, changes to our business practices, negative publicity, reputational harm, or, in cases for which injunctive relief is sought, an injunction prohibiting us from manufacturing or selling one or more of our products or technologies. As a result of the conclusion of any matter, including a settlement or an unfavorable ruling on a matter, our business, operating results or financial condition could be materially harmed... We seek to diligently protect our IP rights and will continue to do so."
