The investigation adds legal overhang on Monolithic Power Systems, potentially further depressing its stock price and harming investor confidence. Nvidia's shift to competitors may reduce Monolithic's revenue and market share in the power management semiconductor space.

Event Summary

Kahn Swick & Foti, LLC (KSF) has commenced an investigation into Monolithic Power Systems, Inc. (MPWR) regarding potential breaches of fiduciary duties by its officers and directors. The investigation follows a November 2024 report by Edgewater Research revealing that Nvidia, Monolithic's largest customer, cancelled half of its outstanding orders and plans to eliminate Monolithic's allocation for next-generation Blackwell chips due to performance issues. Subsequently, a securities class action lawsuit was filed against Monolithic and certain executives for failing to disclose material information. KSF's investigation focuses on whether Monolithic's leadership violated state or federal laws.
