Super Micro Computer (SMCI) shares traded near $37 in early Wednesday trading, following a 4.3% gain on Tuesday. The uptick came as part of a broader rally in AI hardware stocks, sparked by a UBS price-target hike for Micron Technology (MU). The move lifted not just Micron but also other 'picks-and-shovels' names in the AI infrastructure space, including AMD (AMD), Dell (DELL), HPE (HPE), Arista (ANET), and Vertiv (VRT).
The rally was notable because it was not driven by any fresh company-specific news from Super Micro itself. Instead, traders interpreted the Micron surge as a signal that demand for AI infrastructure—spanning chips, memory, servers, networking, and cooling—remains robust, potentially outstripping supply.
However, the company's underlying financial health remains a concern. In its fiscal third quarter, Super Micro reported net sales of $10.24 billion, more than double the $4.60 billion from the same period last year. Yet its gross margin—the percentage of revenue left after product costs—stood at just 9.9%. This thin margin has been a persistent issue, casting a shadow over the revenue growth story.
During the quarter, AI GPU platforms accounted for over 80% of revenue, highlighting the company's heavy reliance on the AI boom. Management guided for fiscal fourth-quarter sales of $11.0 billion to $12.5 billion and fiscal 2026 sales of $38.9 billion to $40.4 billion. CEO Charles Liang emphasized the company's transformation into a total data center infrastructure provider, but analysts remain cautious.
Seeking Alpha contributor Tech Stock Pros downgraded Super Micro to sell on Tuesday, noting that the stock had risen about 60% since late March and that the margin recovery appeared vulnerable. The note cited guidance implying sub-9% margins and warned that memory and CPU shortages could hinder near-term revenue recognition.
David Jagielski of The Motley Fool also flagged the low margins, earlier accounting concerns, and the company's dependence on AI-fueled growth as reasons the stock remains risky despite its seemingly cheap valuation.
In prepared remarks, CFO David Weigand said orders and backlog remain strong, with two customers each accounting for more than 10% of fiscal third-quarter revenue, including one large data center customer at 27%. However, the company has warned that larger customers can make sales less predictable and pressure margins.
Peer comparisons underscore the challenge. AMD reported first-quarter revenue of $10.3 billion—close to Super Micro's quarterly sales—but posted a gross margin of 53% and net income of $1.4 billion. This gap explains why a chip designer like AMD commands a far richer market valuation than a company assembling lower-margin AI server systems.
The broader market signal from Micron, driven by UBS raising its price target to $1,625 from $535, cited stronger AI demand and long-term supply deals that could reduce earnings volatility in DRAM and NAND memory. UBS argued there was 'no reason' Micron should trade much differently from Nvidia (NVDA) on a price-to-earnings basis if AI demand continues reshaping the sector.
Super Micro also faces potential headwinds from an independent board review tied to export-control issues. While the company has said it was not named as a defendant in that case, the review could affect forecasts or past results. Gabelli Funds portfolio manager Hendi Susanto noted that investors may weigh risks including further investigation, audits, costs, and negative reputation.
For now, Super Micro trades on two clocks: one tracking the AI buildout, where memory shortages and rising cloud spending lift all hardware suppliers, and the other tracking cash, margins, and customer concentration. The company needs both clocks to run in its favor.
