Supermicro stock took a massive hit on March 20 after co-founder Yih-Shyan "Wally" Liaw, sales manager Ruei-Tsan "Steven" Chang, and contractor Ting-Wei "Willy" Sun were indicted on charges of conspiring to unlawfully divert cutting-edge U.S. artificial intelligence technology to China. The company's share price plunged over 33% after the news became public servers containing $2.5 billion worth of Nvidia banned artificial intelligence chips had allegedly been smuggled to Chinese customers from 2024 to 2025.
Through inclusion in Supermicro servers that were allegedly mislabeled, the band chips were allegedly sold to a Southeast Asian company and rerouted to China in violation of the Export Control Reform Act. Four Chinese universities, two of which have ties to the military, bought the restricted Supermicro servers. On the other hand, Supermicro has not been directly named as a defendant in any related crimes.
Supermicro stock has seen some modest recovery momentum early in April thanks to bullish momentum for the broader market. The company's share price is up roughly 2.6% in the month so far amid a 3.9% gain for the S&P 500 and a 4.8% gain for the Nasdaq Composite.
Supermicro computer has seen massive sales gains in conjunction with the artificial intelligence revolution. The company's business revolves around producing pre-made servers using mostly components from third parties, with Nvidia's advanced processors being the most important piece of its hardware boxes.
Supermicro products built around these Nvidia chips for training artificial intelligence make up around 70% of the company's revenue, and the server specialist's business could be severely impacted if Nvidia chose to distance itself from Supermicro. There is no current long-term contract between the companies.
Supermicro has disclosed that an independent investigation as begun regarding Liaw, Chang, and Sun, but a definitive timetable for the investigation has not yet been set. The company has reaffirmed its commitments to U.S. export laws, but big questions regarding its future remain -- and shares could continue to be volatile in the near term.
