Super Micro $SMCI surges 18% as fiscal Q3 revenue more than doubles, guidance beats

Revenue Doubles, Guidance Beats — Super Micro Rebounds

Super Micro Computer ($SMCI) shares jumped 18% after hours on May 5, 2026, after the AI server maker reported fiscal third-quarter results that decisively beat on both the top line and forward guidance. Revenue more than doubled year-over-year, driven by strong demand for its GPU-dense rack-scale server systems used in AI data centers.

Management flagged notable progress on U.S. manufacturing expansion — a key focus for investors and policymakers amid broader onshoring efforts in the semiconductor supply chain. Domestic production ramp supports both cost control and customer relationships with hyperscalers seeking U.S.-made hardware.

The result is a significant turnaround for Super Micro, which faced accounting-related scrutiny and a delayed annual filing in fiscal 2025. The strong Q3 result suggests operational momentum has outpaced its earlier compliance issues.

Super Micro competes directly with Dell ($DELL) and Hewlett Packard Enterprise ($HPE) in the AI server market. An 18% single-day move signals that institutional investors are pricing in continued AI-driven demand through at least the end of fiscal 2026.
