Shareholders of Super Micro Computer Inc on Wednesday sued the Silicon Valley server maker, accusing it of committing securities fraud by concealing its dependence on sales to China that violated US export laws, leading to criminal smuggling charges involving Nvidia Corp chips against a cofounder and two others linked to the company.
In a proposed class action suit filed in San Francisco federal court, shareholders said Super Micro overstated its business prospects and inflated its stock price by knowingly failing to disclose that a significant portion of server sales went to companies in China, and the company had material weaknesses in its compliance with export control laws.
Super Micro shares sank 33 percent on Friday last week after criminal charges were announced a day earlier against Liaw Yih-shyan (廖益賢), a cofounder and director; Chang Ruei-tsang (張瑞滄), a sales manager in Taiwan; and Sun Ting-wei (孫廷瑋), a contractor.

The decline wiped out about US$6.1 billion of the San Jose, California-based company’s market value, and Liaw resigned from Super Micro’s board.
Other defendants in the civil lawsuit are Super Micro CEO Charles Liang (梁見後) and chief financial officer David Weigand.
Super Micro did not respond to requests for comment.
Prosecutors said Liaw and Chang directed an unnamed company in Southeast Asia to buy servers with Nvidia’s chips, and that the company bought US$2.5 billion of servers in 2024 and last year.
Super Micro has said it is cooperating with the US government, and the alleged criminal conduct violates its policies.
Neither Super Micro nor Nvidia was criminally charged, and Nvidia is not a defendant in the shareholder lawsuit.
It is common for shareholders to sue companies after unexpected negative news causes stock prices to decline.
Wednesday’s lawsuit seeks unspecified damages for Super Micro investors between April 30, 2024, and March 19.
ENERGY ISSUES: The TSIA urged the government to increase natural gas and helium reserves to reduce the impact of the Middle East war on semiconductor supply stability Chip testing and packaging service provider ASE Technology Holding Co (日月光投控) yesterday said it planned to invest more than NT$100 billion (US$3.15 billion) in building a new advanced chip testing facility in Kaohsiung to keep up with customer demand driven by the artificial intelligence (AI) boom. That would be included in the company’s capital expenditure budget next year, ASE said. There is also room to raise this year’s capital spending budget from a record-high US$7 billion estimated three months ago, it added. ASE would have six factories under construction this year, another record-breaking number, ASE chief operating officer Tien Wu
The EU and US are nearing an agreement to coordinate on producing and securing critical minerals, part of a push to break reliance on Chinese supplies. The potential deal would create incentives, such as minimum prices, that could advantage non-Chinese suppliers, according to a draft of an “action plan” seen by Bloomberg. The EU and US would also cooperate on standards, investments and joint projects, as well as coordinate on any supply disruptions by countries like China. The two sides are additionally seeking other “like-minded partners” to join a multicountry accord to help create these new critical mineral supply chains, which feed into
For weeks now, the global tech industry has been waiting for a major artificial intelligence (AI) launch from DeepSeek (深度求索), seen as a benchmark for China’s progress in the fast-moving field. More than a year has passed since the start-up put Chinese AI on the map in early last year with a low-cost chatbot that performed at a similar level to US rivals. However, despite reports and rumors about its imminent release, DeepSeek’s next-generation “V4” model is nowhere in sight. Speculation is also swirling over the geopolitical implications of which computer chips were chosen to train and power the new
TECH WINNERS: Taiwan and South Korea reported robust trade, which suggests that they have critical advantages in the rapidly expanding AI supply chain, an official said Exports last month surged to a new high, as booming demand tied to artificial intelligence (AI) infrastructure fueled shipments of advanced technology components, underscoring the nation’s pivotal role in the global semiconductor supply chain. Outbound shipments climbed to US$80.18 billion, the highest ever for a single month, rising 61.8 percent from a year earlier and marking the 29th consecutive month of growth, the Ministry of Finance said yesterday. “The surge was driven primarily by global investment in AI infrastructure,” Department of Statistics Director-General Beatrice Tsai (蔡美娜) said. The mass production of next-generation AI computing systems has accelerated procurement across the semiconductor supply
