美超微（Super Micro Computer, SMCI）及其創辦人家族近期捲入一起涉及高階伺服器走私的重大指控。需要特別注意的是，美超微（Supermicro）與超微（AMD）是完全不同的公司，前者以伺服器硬體為主，後者則是晶片製造商，兩者不可混淆。

事件的核心在於，美國檢方起訴與美超微相關的家族成員，指控他們非法將價值高達25億美元、搭載英偉達（NVIDIA）高階晶片的伺服器運往中國。儘管創辦人梁見後（Charles Liang）本人並未列入首波逮捕名單，但調查鎖定其家族，尤其是其三弟梁見達，其所掌管的肯微科技被指為走私鏈的重要節點。整個走私過程主要透過新加坡、馬來西亞及泰國等地的「白手套」公司進行，以繞過美國出口管制，將受管制的NVIDIA GPU（包括 A100、H100 系列）運往中國。

這起事件對美超微造成了明顯的衝擊。股價因負面消息及早前審計師安永（EY）辭任等財務爭議而大幅下跌，市場信心隨之動搖。在業務層面，美超微因面臨禁令而一度無法取得NVIDIA GPU晶片，同時需接受美國司法部（DOJ）更嚴格的合規調查。此外，外媒與分析師指出，美超微與梁氏兄弟旗下企業（如大訊、肯微）之間存在高度親信交易與供應鏈綁定，這被視為管理上的重大風險和黑洞，對公司長期治理造成疑慮。

在辨析公司身份時，美超微（Supermicro/SMCI）由梁見後創立，主要聚焦AI伺服器，是此次走私與調查的核心對象；而超微（AMD）則是由蘇姿丰領導的晶片製造商，雖然近期因AI需求而股價波動，但並未涉及本案。

Super Micro Computer (SMCI) and members of its founding family have recently been embroiled in serious allegations involving the smuggling of high-end servers. It is important to note that Supermicro and AMD are entirely separate companies: the former focuses on server hardware, while the latter is a chip manufacturer, and they should not be confused.

The core of the case involves U.S. prosecutors charging family members associated with Supermicro for allegedly illegally shipping servers equipped with high-end NVIDIA chips worth up to $2.5 billion to China. Although founder Charles Liang was not included in the initial wave of arrests, the investigation targeted his family, particularly his younger brother, Liang Jianda, whose company, Kingway Technology, is alleged to have played a key role in the smuggling network. The operation reportedly used “white glove” companies in Singapore, Malaysia, and Thailand to bypass U.S. export controls, transporting controlled NVIDIA GPUs such as the A100 and H100 series to China.

The incident has had a significant impact on Supermicro. Its stock price plummeted due to the negative news and earlier financial controversies, including the resignation of auditor Ernst & Young (EY), undermining market confidence. Operationally, Supermicro faced difficulties obtaining NVIDIA GPUs due to export restrictions and is subject to more stringent compliance investigations by the U.S. Department of Justice (DOJ). Additionally, media and analysts have noted that Supermicro’s close business ties with the Liang brothers’ other companies, such as Dashun and Kingway, involve deeply intertwined transactions and supply chains, representing a major governance risk and internal blind spot for the company.

In distinguishing the two companies, Supermicro (SMCI) was founded by Charles Liang and focuses on AI servers, making it the central subject of this smuggling investigation. AMD, led by Lisa Su, is a chip manufacturer; although its stock has recently fluctuated due to AI demand, it is not involved in this case.
