The charges against Supermicro's co-founder and employees for smuggling AI technology to China caused Supermicro's stock to plummet significantly. This event highlights the ongoing US-China tech rivalry and the strict enforcement of export controls, which could impact other semiconductor and technology companies involved in AI hardware trade.
Yih-Shyan Liaw, a co-founder and senior vice president of Supermicro, along with Ruei-Tsang Chang, a sales manager, and Ting-Wei Sun, a contractor, were charged by the United States — United States Department of Justice with conspiring to illegally divert billions of dollars in artificial intelligence technology to China. The scheme involved selling high-performance computer servers, assembled in the United States with Nvidia GPUs, through a Southeast Asian intermediary company, knowing they would be sent to China in violation of US export controls. The defendants allegedly used fabricated documents, staged dummy equipment for audits, and repackaged servers in unmarked boxes to conceal their true destination. The alleged operation generated approximately $2.5 billion in sales for Supermicro since 2024, with at least $510 million worth of servers diverted between April and May 2025. Supermicro stated it is cooperating with the investigation, has placed Liaw and Chang on administrative leave, and terminated its relationship with Sun. The company's shares fell sharply following the announcement.
