Shares of Super Micro Computer (SMCI) have been sued by shareholders alleging that the company overstated its growth prospects by failing to disclose that a significant portion of its server sales were linked to China, potentially violating U.S. export controls. The lawsuit, filed in federal court in San Francisco, alleges that Super Micro had material weaknesses in its compliance systems and presented a stronger business outlook to investors. This comes after criminal charges were brought against co-founder Yih-Shyan Liaw and two others for orchestrating sales of servers containing Nvidia chips to China through a Southeast Asian intermediary. The company's stock dropped 33% after the charges were disclosed, wiping out roughly $6.1 billion in market value.
