Super Micro Computer (SMCI) shares fell 11.30% to $26.99 as federal prosecutors investigated allegations that entities linked to Alice Huang smuggled company products into China. The decline followed reports that the Department of Justice is scrutinizing these smuggling efforts, a development that intensified existing concerns over the company’s governance and operational risks.

What Happened

Federal prosecutors are investigating whether entities connected to Alice Huang were involved in efforts to smuggle Supermicro products into China. The company stated that it has fully cooperated with authorities in the United States, Taiwan, and Singapore. While the probe centers on Supermicro, reports indicate that Nvidia and Megaspeed are also facing separate DOJ inquiries, though no charges have been indicated against Nvidia or its leadership. Supermicro reported third-quarter adjusted earnings per share of 5 cents, a significant improvement from the 61-cent loss reported in the same period last year. The company also clarified that Megaspeed was never a customer, a detail highlighted in recent reporting.

The session low hit $25.70 at 11:55 AM ET. Over the last 8 sessions, the stock has declined 14.0%. Fundamentals show a market cap of $18.3 billion and a P/E ratio of 6.4, with trailing twelve-month revenue up 156.5%. The 52-week range spans from $19.48 to $51.40.
