Federal Indictment Targets Super Micro Associates


The U.S. Attorney’s Office for the Southern District of New York has unsealed an indictment charging three individuals connected to server manufacturer Super Micro Computer with violating the Export Control Reform Act. The defendants—co-founder Yih-Shyan “Wally” Liaw, sales manager Ruei-Tsan “Steven” Chang, and contractor Ting-Wei “Willy” Sun—are accused of orchestrating a scheme to illegally divert advanced servers containing Nvidia chips to China.


According to court filings, the group utilized a Southeast Asian intermediary to create fraudulent paperwork, presenting the company as the end-user of the technology. In reality, the servers were repackaged and smuggled into China. To deceive compliance teams and U.S. export control officers, the defendants allegedly set up dummy servers at inspection sites while the actual hardware was shipped abroad.


Company Response and Market Reaction


Following the announcement, Super Micro’s stock price tumbled approximately 12% in extended trading. The company, while not named as a defendant, confirmed the indictment of the individuals involved. A statement from the server maker noted that Liaw, Chang, and Sun have been placed on leave or had their contracts terminated. The firm emphasized that the alleged conduct violates its internal policies and stressed its commitment to maintaining a robust compliance program.


Deception Tactics and Scale


Prosecutors detailed a sophisticated operation designed to circumvent national security protocols. The indictment alleges that Liaw pushed for the adoption of Nvidia’s advanced Blackwell architecture chips, communicating with the intermediary to accelerate shipments before new export rules took effect. It is estimated that the scheme generated roughly $2.5 billion in sales since 2024.


Authorities stated that Liaw and Sun were arrested on Thursday, while Chang remains a fugitive. The case highlights the ongoing struggle U.S. authorities face in preventing sensitive AI technology from reaching foreign rivals, particularly as demand for high-performance computing components continues to surge globally.
