Prosecutors are checking whether groups tied to Alice Huang tried to smuggle Super Micro products into China. Huang is an executive at Singapore-based data-center firm Megaspeed.
What the probe covers
The Justice Department is already investigating a chip-smuggling campaign linked to Huang and Megaspeed. She is also suspected of spying for the Chinese government.
Huang is the woman at the center of the Nvidia scandal involving Jensen Huang. He admitted to an affair but did not name her, and he resigned as Nvidia CEO on Thursday.
Super Micro pushed back in a statement. It said Megaspeed has never been a customer.
The company also said it has fully cooperated with US and Taiwanese officials. It has given information to Singapore authorities as well.
The Justice Department declined to comment. The US Attorney’s Office did not respond to a request for comment.
A timeline of Super Micro’s legal trouble
This is not Super Micro’s first brush with regulators.
In 2020, the SEC charged the company with widespread accounting violations. It settled and agreed to pay a $17.5 million civil penalty.
In 2024, Hindenburg Research questioned the company’s accounting. Its auditor, EY, later resigned over concerns about transparency and internal controls.
In March, prosecutors in the Southern District of New York unsealed an indictment. It said Yih-Shyan “Wally” Liaw and two others set up a scheme to send servers to China, and Liaw resigned right away.
Taiwanese investigators later raided Super Micro’s office and other sites in Taiwan. That was part of a wider probe into how restricted Nvidia chips reached Asia.
In August, Super Micro said an internal review led by independent board members was finished. It found no evidence that current senior managers knew of the alleged scheme.
The company said it added recommended upgrades to its export compliance program. Rival Dell is up roughly 200% this year, and its stock was about flat on Thursday after a sharp early drop.
