Monolithic Power Systems, Inc. (NASDAQ: MPWR) Investor Reminder: Schubert Jonckheer Investigating Possible Wrongdoing After 30% Stock Drop and Key Court Rulings

SAN FRANCISCO, Oct. 26, 2026 /PRNewswire/ -- Schubert Jonckheer & Kolbe LLP reminds Monolithic Power Systems, Inc. (NASDAQ: MPWR) investors that the firm is investigating potential wrongdoing at the company following a 30% stock drop and court rulings that key claims in a securities fraud lawsuit against Monolithic Power and its CEO and former CFO will move forward. Current shareholders are encouraged to contact the firm here: https://www.classactionlawyers.com/monolithicreminder.

The lawsuit alleges Monolithic Power misled investors between February and November 2024 about the quality and performance of the company's power management integrated circuits and relationship with its key customer, Nvidia, causing its stock to trade at artificially inflated prices. On May 6, 2026, U.S. District Judge James L. Robart found the complaint sufficiently alleged that defendants acted with an intent to deceive or with deliberate recklessness in making these misleading statements, and on October 22, 2026, again rejected defendants' attempt to dismiss the case. During this period, company insiders sold over $160 million in stock. When the truth was revealed that Nvidia had shifted business to competitors amid persistent product quality issues, the stock price fell 30%.

We are investigating potential wrongdoing by Monolithic Power's directors and officers in connection with these allegations.
