Super Micro Computer stock jumps 17% on $4B revenue forecast, analysts cautious

Super Micro Computer shares surged up to 17% in after-hours trading Tuesday after the AI server maker raised its quarterly revenue forecast by $4 billion, now projecting $18.5 billion to $19.5 billion for the September quarter. The company also improved its gross margin outlook to 12%–12.5%, citing stronger demand for AI platforms and a better product mix. The surprise lifted rival stocks Dell Technologies and Hewlett Packard Enterprise, though analysts remain split on whether exceptional server sales will translate into sustainable cash generation and profitability. Supermicro will release full fiscal first-quarter results on November 3, when investors can examine operating cash flow, inventory, and customer concentration—one client accounted for 28.1% of fiscal 2026 revenue. Wall Street maintains a Hold consensus among 18 analysts, with price targets ranging from $15 to $60.
