Super Micro Closes Fiscal 2026 at $11.1B Q4 Revenue as AI Capex Backlog Deepens
Super Micro Computer reported fourth-quarter fiscal year 2026 net sales of $11.1 billion on August 11, 2026, up from $10.2 billion in the prior quarter and nearly double the $5.8 billion posted in Q4 FY2025. Super Micro IR
The result landed near the low end of the company's own $11.0 billion to $12.5 billion guidance range, as flagged in a preliminary business update on July 21. Super Micro IR That same update disclosed $60 billion in fourth-quarter orders booked and gross margins roughly double prior guidance, which sent shares up nearly 20% on July 22. WSJ Reuters The rally faded the following session: shares finished down 3% on July 23 as broader big-tech earnings revived concerns about AI infrastructure spending durability. Reuters
Wall Street analysts had modeled Q4 revenue at $11.67 billion. The $11.1 billion actual fell short of that consensus but still delivered 91% year-over-year growth. The company's outlook for Q4 included approximately $95 million in expected stock-based compensation, a metric worth watching given the equity-dilution implications for a hardware business operating at scale.

Fiscal 2026 Trajectory
Super Micro's fiscal year traced a steep upward arc. Management initially projected fiscal 2026 revenue of at least $33 billion in August 2025, against analyst consensus of $29.94 billion. Reuters By November, the company raised its full-year forecast to $36 billion and said demand would remain robust for the remainder of fiscal 2026. Reuters Quarterly revenue guidance climbed in parallel: Q2 FY2026 results (reported February 3, 2026) guided Q3 net sales of at least $12.3 billion. Super Micro IR
The AI-server market backdrop has been expanding rapidly. As of May 29, 2026, sales of AI-optimized servers reached $16.1 billion across Dell, Super Micro, and Lenovo, according to WSJ live coverage. WSJ Super Micro's Q4 order book of $60 billion signals that demand is still outpacing the company's delivery capacity, which is why revenue can fall short of Street estimates while the stock initially rallies on margin strength.
CoreWeave and the Capex Spiral
The demand signal extends well beyond server OEMs. CoreWeave, the GPU cloud provider, reported Q2 2026 revenue of $1.21 billion, beating estimates of $1.08 billion. Its revenue backlog stood at approximately $104 billion as of June 30, 2026, up from $99.4 billion at the end of Q1 and $66.8 billion at the close of fiscal 2025. CoreWeave IR
CoreWeave's capital spending trajectory has escalated in lockstep. Initial 2026 capex guidance of $30 billion to $35 billion was set in February alongside Q4 2025 results, up from a prior run rate of $14.9 billion. Reuters By May, the lower bound was lifted to $31 billion. Reuters The most recent figure, reported August 11, 2026, places 2026 capex between $35 billion and $39 billion. Reuters CoreWeave also closed a $2.6 billion loan facility on August 10, 2026. CoreWeave IR
SpaceX has moved in the same direction. The company poured $15.83 billion into AI capital spending in Q2 2026, up from $749 million a year earlier. Reuters
The aggregate is staggering. CoreWeave alone is committing up to $39 billion in a single year. SpaceX added roughly $16 billion in a single quarter. Super Micro booked $60 billion in quarterly orders. These are not isolated data points; they are signals from different layers of the AI infrastructure stack — compute providers, hyperscalers, and server OEMs — all converging on the same conclusion: AI build-out is still accelerating into the back half of 2026.
Macro Cross-Currents
The August 11 earnings releases land on the eve of the July CPI report, due August 12, 2026. Economists polled by Reuters expect headline inflation of 3.4% year over year, with core CPI at 2.5%. Reuters The print arrives against a market backdrop that has been pricing in optimism: the S&P 500 closed at a record high on Friday, August 7, capping a strong week for major indexes. Reuters
WSJ's live coverage for August 10 flagged Super Micro alongside Berkshire Hathaway and Sunrise Energy as stocks to watch heading into the CPI release. WSJ The June 10 CPI edition, which saw the Dow drop 953 points, is a reminder that inflation surprises can override micro-level earnings momentum in short order. WSJ
The tension is straightforward. AI capex is running at a pace that implies sustained, multi-year hardware demand. But the cost of capital that funds that build-out — through CoreWeave's debt facilities, SpaceX's internal reinvestment, and customer financing of server purchases — remains tethered to Federal Reserve policy. A hot CPI print on August 12 could compress equity multiples across the AI infrastructure complex even as backlog and order data continue to strengthen. The June 30 Nasdaq advance suggests markets have been leaning toward a benign rate path. WSJ Whether that leaning survives tomorrow's data is the immediate question.
