Super Micro Computer stock climbed 8.3% to $24.05, shrugging off news that shareholders have filed a lawsuit against the AI server maker. The legal action follows a China-linked criminal case targeting co-founder Yih-Shyan Liaw and two other individuals connected to the company. Super Micro itself faces no charges.
The rebound comes as Super Micro searches for footing after its shares dropped 33% on March 20, erasing roughly $6.1 billion in market cap. A fresh civil lawsuit keeps export-control questions front and center for investors—right when the company is still projecting at least $40 billion in fiscal 2026 revenue from its AI server business.
A proposed class action landed in San Francisco federal court this Wednesday, accusing Super Micro of concealing its dependence on sales to China—a move shareholders say ran afoul of U.S. export rules. Investors claim the company didn’t come clean about key weaknesses in its export-control compliance. The complaint, which also names CEO Charles Liang and CFO David Weigand, is seeking damages for anyone who bought Super Micro shares from April 30, 2024 through March 19, 2026.
This civil suit comes on the heels of criminal charges unsealed last week against Liaw, Ruei-Tsang Chang (a sales manager), and contractor Ting-Wei Sun. Prosecutors say the trio pushed at least $2.5 billion worth of U.S.-made AI servers through Taiwan and Southeast Asia, ultimately bringing them into China and sidestepping U.S. export controls. Those rules are supposed to restrict shipments of advanced AI chips and related systems to China.
Super Micro last week called the alleged conduct a violation of its policy and compliance rules. The company put Liaw and Chang on leave, severed its relationship with Sun, and tapped DeAnna Luna as acting chief compliance officer. It also stated that Liaw’s board exit wasn’t related to any internal clash.
Target cuts are rolling in. Nehal Chokshi at Northland dropped coverage to Market Perform, now with a $22 price target. Chokshi said the compliance moves “appear reactionary rather than proactive,” flagging likely “flattish” growth for both revenue and earnings. BofA trimmed its own target to $24, calling the situation “another negative on Super Micro’s brand” and cautioning that customers might slow down orders or shift business to competitors. TipRanks
Caution is bumping up against a business that had been expanding fast before the legal blow landed. Back in February, Weigand noted “order strength remains strong” among big data-center and enterprise clients, after Super Micro raised its fiscal 2026 revenue forecast to at least $40 billion. According to Emarketer analyst Gadjo Sevilla, the company’s trajectory hinges on its position as an integrator for major cloud and AI customers. Reuters
Also in play: new products. On March 24, Arm noted that Supermicro is one of the system partners rolling out early systems for its AGI CPU—a data center chip designed for AI tasks. The move highlights the ongoing importance of server builders in fueling the next phase of AI infrastructure investment.
That’s why there’s more in play than just a single stock. Melius Research last week called Dell the likely winner if buyers rethink which suppliers they trust. Earlier this month, Reuters pointed out that Hewlett Packard Enterprise is locked in direct competition with both Dell and Super Micro when it comes to AI servers. Back in February, Dell projected its AI server revenue will double for fiscal 2027.
For Super Micro, there’s more at stake if the fallout spills beyond just a few ex-employees or the currently suspended. Should suppliers start pulling back on components, or if regulators dig deeper and customers hesitate, that bounce in the shares could evaporate in a hurry. Shana Orczyk Sissel at Banríon Capital summed it up as just the latest batch of “negative headlines” dogging a name that was already drawing plenty of investor attention. TipRanks
