SMCI Quarterly Revenue Could Reach $19.5 Billion, Shares Jump Over 15% After Hours: AI Server Demand Surges, but Profit and Cash Flow Still Need Verification
- Key Takeaways: Super Micro Computer (SMCI) sharply raised its revenue guidance for the first quarter of fiscal 2027 to $18.5 billion to $19.5 billion, roughly 27% above its original guidance, confirming strong AI hardware demand. However, the low margins under its system integration model, high working capital consumption, and customer concentration remain core constraints on its valuation discount.
- Key Elements:
- Revenue guidance of $18.5 billion to $19.5 billion, raised about 27% from the August guidance and roughly 25% above market consensus, implying year-over-year growth of 278.6% and quarter-over-quarter growth of 70.9%; the stock rose more than 15% after hours at one point, lifting memory and optical communications names such as Micron, Lumentum, and Coherent.
- Profit structure is constrained by the system integration segment: Nvidia's net margin reaches 71.5%, while SMCI's best quarter in fiscal 2026 posted a net margin of only 10.6%, with 5.7% for the full year; material costs account for about 88% of revenue, with pricing power concentrated at the chip level.
- Gross margin guidance recovered to 12% to 12.5%, about 2 percentage points higher than the August guidance, but still below the 17.5% actually recorded last quarter; gross margin has fluctuated widely between 6.3% and 17.5% over the past several quarters, and the sustainability of the improvement needs confirmation in the full earnings report.
- Fiscal 2026 revenue grew 77.8%, but operating cash flow showed a net outflow of $6.81 billion, a $9.04 billion gap versus net income of $2.23 billion, mainly due to a 125.1% surge in inventory and a lengthening of the fronting cycle to about 127 days.
- Customer concentration is high: a single large data center customer contributed about 63% of revenue in the second quarter of fiscal 2026, while the largest customer accounted for 27% in the third quarter; Citi maintains a Hold rating, viewing the valuation discount as reasonable until customer concentration and cash conversion improve, with the current price-to-sales ratio at about 0.44x.
- Rising memory prices are pushing up costs: server DRAM contract prices have cumulatively risen about 270% in 2026, while enterprise SSDs are up about 235%; Barclays downgraded Dell and Hewlett Packard Enterprise but raised its AI server order forecasts for them, and whether margins can be sustained is a key focus of the late-November earnings report.
- The full earnings report is scheduled for release on November 3, with three sets of data requiring close scrutiny: the composition of the gross margin improvement, whether the gap between operating cash flow and net income can narrow, and whether the share of large customers declines.
After the U.S. market closed on October 20, Super Micro Computer (SMCI.US) released preliminary results, raising its revenue guidance for the first quarter of fiscal 2027 to $18.5 billion to $19.5 billion. That figure is about 27% above the guidance the company gave in August and about 25% above the prior market consensus. The stock jumped more than 15% after hours, and the next day storage and optical communications names such as Micron, Lumentum, and Coherent moved higher in sympathy. A single-quarter preview, released before full financials, has already told the entire demand-side story. The answers on gross margin, cash flow, and customer concentration will only come with the full report on November 3. This article lays out the numbers that can already be verified, then works through the profit math the market is currently trading on.
1. Revenue Guidance Raised 27% in One Go, Quarterly Revenue Seen at Up to $19.5 Billion
A preliminary preview pulled the AI hardware sector, which had been correcting continuously since early October, back onto the main trading theme. The demand-side signal was confirmed, and the spillover effect spread that evening to Dell, Hewlett Packard Enterprise, storage, and optical communications.
After the U.S. market closed on October 20, SMCI released preliminary results. For the first quarter of fiscal 2027 ended September 30, revenue is expected to be $18.5 billion to $19.5 billion, about 27% above the $14.5 billion to $15.5 billion guidance given in August. The prior market consensus was $15.23 billion; based on the midpoint of $19 billion, the result exceeds it by about 24.8%. Year-over-year growth is 278.6%, and quarter-over-quarter growth is 70.9%.
SMCI's revenue for the entire fiscal 2026 was $39.06 billion. This single-quarter preview, released before full financials, amounts to nearly 48.6% of the prior fiscal year's total. The stock jumped more than 15% after hours and closed at $35.57 on October 21, up 9.55% for the day. According to Futu data, options volume that day was 418,100 contracts, with open interest of 2.388 million contracts, and trading enthusiasm carried into the next session.
The move spread to related names that same evening. According to reports, Dell rose about 6% after hours, Hewlett Packard Enterprise rose about 5%, and CoreWeave and Nebius rose more than 4%. At the October 21 close, Micron gained 6.31%, Lumentum gained 8.52%, Coherent gained 5.66%, and Hewlett Packard Enterprise gained 1.87%, while Dell fell 1.0%. The Philadelphia Semiconductor Index had fallen about 11% cumulatively in October (according to reports), and this rally pulled AI hardware out of its continuous correction. Asian markets reacted in tandem: on October 21, South Korea's KOSPI rose 2.21%, led by semiconductor heavyweights (according to reports).
