March 20 - Super Micro Computer Inc. experienced a severe market setback on Friday, as shares dropped 27% in reaction to U.S. criminal charges filed against three individuals tied to the company. The decline in premarket trading, if it persists through the session, would cut roughly $5 billion from the company's $18.49 billion market capitalization.
The Department of Justice charged three people - the company co-founder Yih-Shyan Liaw, the Taiwan-office sales manager Ruei-Tsang Chang, and contractor Ting-Wei Sun - alleging a scheme to move U.S.-made servers through Taiwan and onward to other Southeast Asian countries, where they were reportedly repackaged in unmarked boxes and ultimately shipped to China.
According to the charges, the accused helped smuggle at least $2.5 billion worth of U.S. AI technology to China. The Justice Department said that products valued at more than $500 million were shipped during a concentrated period between April and mid-May 2025.
Super Micro confirmed it was not named as a defendant in the complaint and stated that it had cooperated with investigators. The company has placed the implicated employees on leave and ended its relationship with the contractor identified in the charges.
The case comes against the backdrop of U.S. export restrictions introduced in 2022 aimed at preventing Chinese military forces from benefiting from advanced technology and at slowing aspects of China’s AI development. Super Micro said earlier that those restrictions affected certain products, including some that contain Nvidia A100 and H100 integrated circuits, among others.
Investor enthusiasm for AI-related hardware had previously driven Super Micro's market value to a peak of $67 billion in 2024. Since that high-water mark, the company has faced margin pressure tied to the costs of building high-performance servers, and its shares were also weighed down by allegations from the now-disbanded short-seller Hindenburg.
Summary
U.S. prosecutors charged three people connected to Super Micro with helping to smuggle U.S. AI servers to China via Taiwan and other Southeast Asian nodes. The allegations involve at least $2.5 billion in technology transfers, including more than $500 million shipped between April and mid-May 2025. Super Micro says it is not a defendant, has cooperated with authorities, and has taken personnel and contractor actions in response.
Key points
- Shares plunged 27% in premarket trading, threatening about $5 billion in market value from an $18.49 billion capitalization.
- Three people tied to the company were charged: co-founder Yih-Shyan Liaw, sales manager Ruei-Tsang Chang, and contractor Ting-Wei Sun.
- At least $2.5 billion of U.S. AI technology was reportedly smuggled to China, with over $500 million of product moved between April and mid-May 2025; earlier U.S. export controls from 2022 have already affected some Super Micro products featuring Nvidia A100 and H100 chips.
Risks and uncertainties
- Legal and compliance risk to the company stemming from criminal charges against individuals associated with Super Micro - this could affect corporate operations and reputation in the technology and server hardware sectors.
- Regulatory and export-control uncertainty linked to U.S. restrictions on advanced chips - potential impacts on product availability and sales for server builders and semiconductor customers.
- Market and valuation risk for investors given prior margin pressure from costly server builds and past allegations from a disbanded short-seller, contributing to heightened share price volatility in the technology and enterprise hardware markets.
