Investigations and authorities' requests
The appointment came amid investigations related to the company. In March 2026, the U.S. Department of Justice and the FBI charged and arrested Supermicro co-founder Yi-Shan “Wally” Liao. According to the investigation, in a case involving the alleged smuggling of $2.5 billion worth of Supermicro equipment, servers with export-controlled Nvidia chips were illegally shipped to China.
Supermicro is not a defendant in the case and has said it is cooperating with law enforcement. Liao pleaded not guilty. An internal review conducted by the board of directors after his arrest found no evidence that current members of senior management knew about the alleged scheme, according to the company.
The company also reported receiving a grand jury subpoena from the U.S. Attorney's Office for the Southern District of New York regarding the charges against Liao, its compliance program and internal controls. Supermicro contractor Ting-Wei “Willie” Sun, who was also charged in the case, pleaded guilty to four counts, including conspiracy to smuggle and obstruction of justice. Weigand will remain with the company during a transition period to assist the new CFO.
