Supermicro Says It Is Cooperating After Taiwan Office Search in NVIDIA AI Server Probe

Taiwanese authorities have searched Supermicro’s Taiwan office as part of an expanding investigation into the alleged diversion of advanced NVIDIA AI server technology toward China. The operation was directed by the Keelung District Prosecutors Office and also included locations connected to Supermicro distributor Albatron Technology and data center operator Chief Telecom. At the time of reporting, prosecutors had not announced charges against Supermicro itself, and a search does not establish wrongdoing by the company.

The latest searches expand an investigation that became public in May 2026, when prosecutors searched 12 locations and detained 3 people suspected of using false documents to export Supermicro AI servers containing restricted NVIDIA accelerators. The official Keelung District Prosecutors Office statement said the suspects allegedly purchased the systems in Taiwan and submitted inaccurate export documents while attempting to move them toward mainland China, Hong Kong, or Macao.

Supermicro previously said its cooperation with Taiwanese authorities contributed to the arrest of 3 suspects and the seizure of 50 servers. According to the company’s May statement, the systems had initially been sold to an authorized reseller after undergoing a review process, but were later acquired through downstream transactions that allegedly concealed their intended destination.

Following the latest search, Supermicro told the Financial Times that it was working closely with Taiwanese authorities and other government agencies to ensure its technology is distributed in accordance with applicable export regulations.

Albatron confirmed through a Taiwan Stock Exchange filing that investigators searched its offices on June 29. The distributor said the event was not expected to create a material effect on its finances or normal operations. Its shares nevertheless reached the 10% daily decline limit in Taiwan on June 30, while Supermicro shares fell approximately 8% in United States trading following reports of the broader investigation.

The Taiwanese case remains separate from a United States prosecution announced in March 2026. The United States Department of Justice charged Supermicro cofounder and former executive Yih Shyan Liaw, Taiwan employee Ruei Tsang Chang, and contractor Ting Wei Sun with allegedly conspiring to divert approximately $2.5 billion of servers containing controlled AI technology to customers in China. Prosecutors allege that the operation used false end user records, a Southeast Asian intermediary, repackaged equipment, and nonfunctional dummy servers to conceal the destination of the working systems. All allegations remain unproven, and the defendants are presumed innocent unless convicted.

Liaw and Sun have pleaded not guilty, while Chang remained outside United States custody when the pleas were entered. Supermicro was not named as a defendant in the indictment. The company placed Liaw and Chang on administrative leave immediately after the charges became public, ended its relationship with Sun, and later confirmed that the 3 individuals no longer had any relationship with the company. Liaw also resigned from Supermicro’s board, while the company appointed an acting Chief Compliance Officer and initiated an independent internal investigation.

The March indictment caused Supermicro shares to lose approximately 33% in a single trading session, reflecting investor concern over compliance exposure and potential disruption to one of the most important suppliers of NVIDIA based AI server systems. Supermicro and Dell both play central roles in integrating advanced NVIDIA accelerators into complete data center platforms for cloud providers, research institutions, and enterprise customers.

Taiwan’s legal position adds another layer of complexity. Unauthorized movement of United States controlled AI hardware toward China is not currently treated as a dedicated criminal offense under Taiwanese law. Investigators have instead relied on allegations involving false documentation, breach of trust, customs declarations, and other domestic offenses. Taiwan has reportedly been considering stronger controls that would more directly align its enforcement framework with United States restrictions on advanced AI technology.

The investigation follows the wider alleged supply chain network previously examined in our report on restricted NVIDIA servers suspected of reaching China through Thailand. That case illustrates how servers can pass through authorized distributors and multiple regional companies before manufacturers lose visibility into their final destination. NVIDIA has started responding to this wider enforcement challenge through optional server telemetry and location verification tools. As covered in our report on the NVIDIA AI GPU location tracking service, the technology is intended to help data center operators monitor accelerator fleets and identify unexpected changes in where systems are operating.

The most important distinction is that Supermicro has not been charged in either the current Taiwanese search or the United States criminal case. However, its products, employees, reseller network, and compliance systems remain central to both investigations, creating significant legal and reputational exposure even without a corporate indictment.

The case demonstrates why conventional customer screening is no longer sufficient for advanced AI infrastructure. A server manufacturer can approve a legitimate reseller and still lose visibility after products move through secondary buyers, logistics companies, and international intermediaries. As Blackwell generation systems become more valuable, manufacturers will face growing pressure to implement continuous asset verification rather than relying only on documents submitted before shipment.

For Taiwan, the investigation could accelerate a wider policy shift. The island is a critical manufacturing and distribution hub for global AI hardware, but its current domestic laws do not directly mirror every United States export restriction. Stronger coordination may reduce diversion risks, although it could also increase compliance costs and operational delays across the regional server supply chain.

Should AI server manufacturers be required to track the location of restricted GPUs after delivery, or would that create excessive control over customer owned hardware?
