Super Micro Computer, Inc. is facing multiple class action lawsuits from investors who were allegedly harmed by the company's failure to disclose material information about a scheme to divert servers containing U.S. artificial intelligence technology to customers in China, violating export control laws. The lawsuits cover the period from February 2, 2024 to March 19, 2026, when the U.S. Department of Justice announced the unsealing of an indictment against three individuals associated with Super Micro.

Why it matters

The alleged export control violations and subsequent lawsuits raise concerns about Super Micro's corporate governance and compliance practices, as well as the potential financial and reputational damage the company may face. Investors will be closely watching how the cases unfold and whether the company can recover from the fallout.

The details

According to the complaints, Super Micro and certain executives are accused of failing to disclose that three individuals - Yih-Shyan Liaw (the company's co-founder, director, and Senior Vice President of Business Development), Ruei-Tsang Chang (a general manager in the Taiwan office), and Ting-Wei Sun (a third-party broker) - were engaged in a scheme to divert servers containing U.S. artificial intelligence technology to customers in China, violating export control laws. This allegedly enabled the sale of approximately $2.5 billion worth of servers between 2024 and 2025.

  • On March 19, 2026, the U.S. Department of Justice announced the unsealing of an indictment against the three individuals.
  • On March 20, 2026, Super Micro's stock price fell 33.3% to $20.53 per share.
