Super Micro Computer just offered one of the clearest signals yet that enterprise AI spending isn’t slowing down. The company’s CFO disclosed that nine customers each generated more than $1 billion in revenue during fiscal year 2026, more than doubling the four customers that hit that mark in FY25.
The numbers behind the surge #
Supermicro, which trades on NASDAQ under the ticker SMCI, provided a preliminary business update on July 21 ahead of its full FY26 earnings call scheduled for August 11. The company’s fiscal year ends June 30, meaning FY26 is now in the books.
Preliminary Q4 revenue is expected to land near the lower end of the company’s $11.0 to $12.5 billion guidance range. GAAP and non-GAAP gross margins are projected to come in between 15% and 17%. Prior forecasts had pegged margins at just 8.2% to 8.4%.
The company reported Q3 FY26 net sales of $10.2 billion. New orders in Q4 alone exceeded $60 billion, pushing the company’s backlog to record levels.
What’s driving the demand #
The company attributed the Q4 demand increase to enterprise and channel customers upgrading their infrastructure. Supermicro has built its recent strategy around AI-optimized systems, frequently paired with Nvidia GPUs.
A turbulent recent history #
The strong FY26 performance arrives after a particularly rocky period for Supermicro. The company faced serious headwinds in 2024 and early 2025 related to accounting concerns, a delayed annual report, and questions about its internal controls.
What this means going forward #
The margin improvement is a notable signal for investors. Margins jumping from the 8% range to 15–17% suggests the company is selling higher-value configurations, likely GPU-heavy systems with premium pricing power.
With the full earnings call set for August 11, investors will be watching for clarity on backlog conversion timelines, customer diversification trends, and whether those elevated margins are sustainable or a one-quarter anomaly driven by product mix.
