The Portnoy Law Firm has filed a class action lawsuit against Super Micro Computer, Inc. on behalf of investors who bought securities between April 30, 2024 and March 19, 2026. The lawsuit alleges that Super Micro made false and/or misleading statements and failed to disclose that a significant portion of its server sales were to companies in China, violating U.S. export control laws, and that there were material weaknesses in the company's compliance controls.

Why it matters

This lawsuit highlights the growing scrutiny on U.S. tech companies over compliance with export control regulations, especially in dealings with China. The alleged violations could result in significant legal and financial penalties for Super Micro, as well as reputational damage that impacts the company's future business prospects.

The details

According to the lawsuit, on March 19, 2026, the U.S. Department of Justice announced the unsealing of an indictment against three individuals associated with Super Micro for engaging in a scheme to divert servers with U.S. artificial intelligence technology to customers in China without the required export licenses. The DOJ stated these activities enabled the sale of approximately $2.5 billion worth of servers between 2024 and 2025.

  • The class period covers securities bought between April 30, 2024 and March 19, 2026.
