Super Micro Faces Shareholder Lawsuit Over Alleged China Export Violations

Shareholders of Super Micro Computer filed a lawsuit against the Silicon Valley-based server maker on March 25, accusing the company of securities fraud. They claim that Super Micro concealed its heavy reliance on sales to China, which allegedly violated US export laws. This led to criminal charges, including smuggling Nvidia chips, against several individuals associated with the company, including co-founder Yih-Shyan Liaw and sales manager Ruei-Tsang Chang. The lawsuit argues that Super Micro misled investors by overstating its business prospects and failing to disclose weaknesses in complying with export controls. After the charges were announced on March 20, Super Micro’s stock value dropped by 33%, wiping out $6.1 billion in market value. The case, filed in San Francisco, seeks unspecified damages for investors who held shares between April 2024 and March 2026. The company has not yet responded to the lawsuit but claims to be cooperating with authorities in the ongoing criminal case, though neither Super Micro nor Nvidia is facing criminal charges. The lawsuit also names CEO Charles Liang and CFO David Weigand as defendants.
