Super Micro Computer reported its fourth-quarter and full-year fiscal 2026 results after the bell on Tuesday, and the stock jumped more than 9% in after-hours trading after the AI server maker issued an outlook that blew past Wall Street's expectations.
The company expects revenue between $65 billion and $72 billion for fiscal 2027 — well above the average analyst estimate of about $52.5 billion. The numbers cap a year of extraordinary growth: fiscal 2026 revenue, which ended in June, nearly doubled to roughly $39.1 billion, driven by insatiable demand for servers and cooling systems for AI data centers.
Supermicro's outlook is widely read as a sentiment test for the entire AI infrastructure supply chain — from chipmakers to networking vendors to the neoclouds that operate the data centers. The company has positioned itself as a leading supplier of high-performance servers for GPU clusters, benefiting from the scramble by hyperscalers and AI labs for fast delivery.
The after-hours rally coincided with a broader rebound in AI stocks as markets looked ahead to US inflation data and the upcoming earnings season for Chinese AI companies. Analysts noted that Supermicro's guidance also reflects how demand for compute has broadened from a few anchor customers to a much wider set of enterprises.
What remains open is whether margins can hold up amid aggressive price competition and rising component costs — an issue that has weighed on the stock in past quarters. For now, though, the signal dominates: the AI hardware boom set new records in the past fiscal year — and Supermicro is betting heavily that it will continue.
