A contractor linked to Super Micro Computer Inc. pleaded guilty on Thursday, Oct. 8, 2026, to charges involving the illegal export of advanced artificial intelligence servers to China. Ting-Wei "Willy" Sun entered the plea in U.S. District Court in Manhattan, admitting to four counts including conspiracies to violate export controls, smuggle goods from the U.S., defraud the country, and obstruct justice.
The plea follows a March 2026 indictment charging Sun and two others associated with Super Micro with conspiring to divert approximately $2.5 billion in U.S. technology to China. According to federal prosecutors, the scheme began around October 2023 and involved exporting servers containing restricted Nvidia chips without the required government licenses.
The indictment identified Sun as a broker and "fixer" who facilitated orders and took steps to conceal the scheme. In December 2025, Sun allegedly helped stage "dummy" servers and made false statements to a U.S. Department of Commerce officer during an inspection of equipment that had already been diverted to China. Also indicted in the case were Super Micro co-founder Yih-Shyan "Wally" Liaw and Ruei-Tsang "Steven" Chang, a former sales manager for the company's Taiwan office.
Super Micro stated that the company itself was not named as a defendant in the indictment and its operations remain unaffected. The company terminated Sun and cut ties with the other defendants earlier in the year.
The legal proceedings signal a continued focus by the Department of Commerce and the Department of Justice on enforcing AI-related export laws. While Sun has entered a guilty plea, the legal status of co-defendants Liaw and Chang remains pending. The U.S. government maintains these restrictions to prevent the use of advanced computing power in foreign military development, citing national security concerns. The indictment stated that Nvidia's B200, H100, and H200 graphics processing units, and servers containing them, were subject to the restrictions.
