Super Micro (SMCI) stock slides 9% after earnings spike — what to watch before Friday’s trade

New York, Feb 5, 2026, 20:04 EST — The market has closed for the day.

  • Super Micro Computer (SMCI) dropped 8.6% to $30.85 Thursday, pulling back after Wednesday’s post-earnings surge.
  • The AI server maker raised its fiscal 2026 sales forecast to $40 billion, even as margins narrowed significantly.
  • Next week’s focus: will demand stay strong as investors dig into profitability and await delayed U.S. jobs data.

Shares of Super Micro Computer Inc dropped 8.6% Thursday, closing at $30.85. The stock held steady at that price in after-hours trading.

This shift is significant since Super Micro now serves as a high-beta indicator for the AI infrastructure ramp-up. This week’s activity reflected not just demand, but also what the company retains after assembling and delivering its hardware.

Super Micro bumped its fiscal 2026 revenue forecast to at least $40 billion from $36 billion on Tuesday, following a quarterly revenue beat. The company noted that roughly $1.5 billion of first-quarter shipments were delayed, while it expects third-quarter revenue around $12.3 billion. “Order strength remains strong,” CFO David Weigand said. Emarketer analyst Gadjo Sevilla described Super Micro as an “integrator” catering to major cloud and AI clients. 1

The quarter ending Dec. 31 highlighted the trade-off. Gross margin — the portion of sales remaining after direct costs — dropped to 6.3% from 9.3% the previous quarter, even as net sales climbed to $12.7 billion, the company reported. Founder and CEO Charles Liang said the company is “scaling rapidly” to back large deployments. 2

On Tuesday, an 8-K filing submitted the quarterly results to the U.S. Securities and Exchange Commission. 3

The stock surged 13.8% on Wednesday following the forecast boost, contrasting with a day when tech shares pulled U.S. indexes down. On Thursday, it fell back, marking a volatile two-day stretch heading into Friday. 4

Thursday’s sell-off hit AI-related stocks hard. The Nasdaq ended at its lowest point since November, dragged down after Alphabet announced a further increase in AI spending. “We’re seeing this volatility about whether this investment will translate, ultimately, into results,” said Tom Hainlin, investment strategist at U.S. Bank Wealth Management. 5

Super Micro saw heavy trading, with roughly 56.6 million shares exchanging hands—more than twice its 50-day average, according to MarketWatch data. 6

Shares of other AI hardware makers also slipped, adding stress to the server and accelerator supply chain. Nvidia slid roughly 1.2%, while AMD tumbled nearly 3.9% on the session.

Yet the earnings report delivered a stark warning. In its SEC filing, Super Micro cautioned that bigger contracts might concentrate its customer base, making sales less predictable. It also flagged risks from costs, tariffs, and pricing pressure that could squeeze margins. 7

With U.S. markets closed, Friday’s trading will show if the stock can hold near $30 after a volatile week. Tech shares, sensitive to interest rates, face a key macro week ahead: the January jobs report, delayed, arrives Feb. 11, followed by January’s CPI data on Feb. 13. 8
