A class action lawsuit has been filed against Super Micro Computer, Inc. (NASDAQ: SMCI) on behalf of shareholders who purchased the company's securities between April 30, 2024 and March 19, 2026. The lawsuit alleges that Super Micro failed to disclose that a significant portion of its server sales were to companies in China, violating U.S. export control laws, and that the company had material weaknesses in its compliance controls.

Why it matters

The allegations against Super Micro, if proven true, could have serious legal and financial consequences for the company. Violations of export control laws can result in hefty fines and criminal penalties, and the revelations have already caused a significant drop in Super Micro's stock price, impacting shareholders.

The details

According to the complaint, Super Micro's co-founder Yih-Shyan Liaw, Taiwan office general manager Ruei-Tsang Chang, and third-party broker Ting-Wei Sun conspired to divert the company's servers with advanced Nvidia GPUs to customers in China without the required licenses from the U.S. Department of Commerce. This allegedly enabled the sale of approximately $2.5 billion worth of servers between 2024 and 2025.

  • On March 19, 2026, the U.S. Justice Department announced the unsealing of an indictment against the three individuals associated with Super Micro.
  • The class period for the lawsuit is April 30, 2024 to March 19, 2026.
