Monolithic Power Systems, Inc. (NASDAQ: MPWR) Investor Alert: Schubert Jonckheer Investigating Possible False Statements Following 30% Stock Drop
Schubert Jonckheer & Kolbe said it is investigating possible securities-fraud claims against Monolithic Power Systems (MPWR) after a 30% stock drop. A May 6, 2026 ruling by Judge James L. Robart let key claims proceed, alleging misleading statements about PMIC quality and Nvidia’s continued integration, with insiders selling over $160M. The decline followed late Oct to early Nov 2024 news that Nvidia shifted to competitors.

Why it matters
A federal judge ruled that key securities-fraud claims against Monolithic Power, its CEO, and former CFO will move forward, and the article links the alleged disclosure period to a later 30% stock decline after Nvidia shifted business to competitors.
Market read
For MPWR, the actionable element is the court’s decision to allow key securities-fraud claims to proceed, which can reprice litigation risk and investor confidence.
