Supermicro is scrambling to contain a crisis of confidence as the company launches a probe after a co-founder’s arrest on charges of $2.5 billion in chip smuggling. The internal investigation follows a federal indictment alleging that Yih-Shyan “Wally” Liaw orchestrated a sophisticated scheme to route high-end servers, packed with Nvidia’s most sought-after GPUs, into China in direct violation of U.S. Export controls.
The board’s latest effort to scrub its operations comes at a precarious time for the server maker. Investors are increasingly worried that systemic compliance failures could alienate Nvidia, the $4 trillion chip giant that serves as Supermicro’s primary supplier. If the relationship with Nvidia is strained, Supermicro’s ability to fulfill purchase orders for AI infrastructure—the engine of its current growth—could be severely compromised.
To lead the investigation, the board has appointed its newest director, Scott Angel, and audit committee chair Tally Liu. The company has retained the law firm Munger, Tolles & Olson, which in turn brought in the consulting firm AlixPartners to provide forensic accounting and audit expertise. These teams will coordinate with Supermicro’s current auditor, BDO USA, and report their findings directly to Angel and Liu.
The ‘Subterfuge’: Hair Dryers and Replica Servers
The Department of Justice indictment paints a picture of an elaborate operation designed to deceive government auditors. According to the charges, Liaw and two other individuals—Ruei-Tsang “Steven” Chang and Ting-Wei “Willy” Sun—conspired during 2024 and 2025 to use an unnamed Southeast Asian company as a front for buyers in China.
The level of detail in the indictment suggests a desperate attempt to maintain a facade of legality. The group allegedly stocked a warehouse with thousands of fake replica servers to trick auditors who were verifying that restricted technology was not being diverted. The subterfuge reportedly included organizing a dedicated team in Southeast Asia to set up these fake units, complete with coordinated van transportation and meals for the staff.
Most strikingly, the indictment claims the trio used hair dryers to peel off packaging labels, which were then reaffixed to the replica servers to mimic legitimate shipments. While Liaw and Sun have pleaded not guilty, Chang remains at large.
During the window of the alleged conspiracy, Liaw served as both a board member and a senior executive. He co-founded Supermicro in 1993 alongside CEO Charles Liang and Liang’s wife, Sara Liu. Supermicro has not been named as a defendant in the indictment and maintains that This proves cooperating fully with the government. CEO Charles Liang has told investors the company was a victim of the scheme, stating that the internal review is part of a commitment to the “highest level of ethical and legal scrutiny.”
A History of Regulatory Friction
For those tracking Supermicro’s corporate governance, this is not the first time the company has faced a reckoning. The current turmoil echoes a pattern of instability involving Liaw and the company’s accounting practices.
Liaw originally retired in February 2018. That exit followed a third board-led investigation tied to an SEC investigation into accounting irregularities and a potential Nasdaq delisting. That saga ended with Supermicro settling with regulators and paying $17.5 million. After a brief stint as president of the French server firm 2CRSi, Liaw returned to Supermicro as a consultant in May 2021, regained a full-time executive role in August 2022, and was reappointed to the board in December 2023. He resigned from the board on March 20, one day after his arrest.
The company’s recent history is summarized in the following timeline of governance challenges:
| Period | Event | Outcome |
|---|---|---|
| 2017–2018 | SEC Accounting Probe | $17.5 million settlement; Wally Liaw retires |
| 2024 | EY Auditor Resignation | EY states it can no longer rely on management |
| 2024 | Internal Export Probe | Found no evidence of circumvention (focused on Russia) |
| 2025–2026 | DOJ Smuggling Indictment | Wally Liaw arrested; $2.5 billion smuggling probe launched |
The Gap in Previous Oversight
One of the most pressing questions for investors is how a previous internal investigation in 2024 failed to catch these activities. Following the abrupt resignation of auditor Ernst & Young (EY)—which stated it could no longer rely on Supermicro’s management—the board appointed director Susie Giordano to lead a special committee.
Working with the law firm Cooley and forensic accountants at Secretariat Advisors, Giordano reviewed 11 export transactions. The resulting report found “no evidence suggesting that anyone at the company tried to circumvent export control regulations,” specifically noting no violations regarding shipments to Russia. Still, those disclosures notably did not mention China.
The 2024 probe did lead to recommendations for structural changes, including the appointment of a chief compliance officer, a chief accounting officer, and a new general counsel. It also suggested that CFO David Weigand be replaced with a professional from a larger public company—a recommendation that the board has yet to act upon, as Weigand remains in his role.
What This Means for the AI Market
Beyond the legal jeopardy for Liaw, this case highlights the extreme pressure on the AI hardware supply chain. Because Nvidia GPUs are subject to strict U.S. Export controls to prevent China from advancing its military and AI capabilities, the “gray market” for these chips has become a high-stakes arena for federal law enforcement.
Supermicro’s ability to prove it has a rigorous global trade compliance program is no longer just a matter of legal housekeeping; it is a prerequisite for its survival as a top-tier partner for the world’s most valuable chipmaker. The company has now initiated a separate internal review of its global trade compliance program, led by general counsel Yitai Hu.
The next critical checkpoint will be the unfolding legal proceedings for Liaw and Sun, alongside any disclosures the board makes regarding the findings of Munger, Tolles & Olson and AlixPartners. These results will determine if the company can convince regulators—and its partners—that the smuggling was the work of a rogue executive rather than a systemic failure of corporate culture.
