Super Micro Stock Jumps 8% After Hours: Revenue Quadruples to $19.9 Billion

Super Micro Computer (NASDAQ: SMCI) stock jumped about 8% in after-hours trading on Tuesday, November 3, 2026, after the AI server maker reported fiscal first-quarter revenue of $19.9 billion — nearly four times the $5.0 billion it booked a year earlier — and raised its full-year sales outlook to $72 billion to $82 billion. The beat landed on a day when investors were openly questioning whether AI spending can keep growing, and Supermicro's numbers were one of the clearest answers yet that data-center demand is still accelerating.

What happened

Supermicro reported unaudited results for its first quarter of fiscal 2027, ended September 30, 2026, after the closing bell. Net sales came in at $19.9 billion, up from $11.1 billion in the previous quarter and $5.0 billion in the same quarter a year ago — a rise of about 298% year over year. Net income rose to $1.594 billion, from $168 million a year earlier, and non-GAAP earnings reached $1.81 a share, well above the $1.23 a share analysts surveyed by FactSet had expected. Revenue also beat the roughly $16 billion to $17.5 billion consensus range reported across outlets, and it cleared the top of the $18.5 billion to $19.5 billion preliminary range the company itself gave on October 20.

The guidance mattered as much as the quarter. For the December quarter, Supermicro expects net sales of $19.5 billion to $21.5 billion, above the roughly $16.5 billion consensus, with non-GAAP earnings of $1.66 to $1.90 a share. For the full fiscal year ending in June, the company now expects $72 billion to $82 billion in sales, raised from its previous $65 billion to $72 billion outlook and above the roughly $69 billion to $73 billion analysts had pencilled in.

Why it is blowing up

Supermicro has become one of the market's purest reads on the AI buildout: it assembles the server racks that house advanced AI chips inside data centers, so its order book moves with hyperscaler spending. A near-quadrupling of revenue in a single year — at a company already doing billions a quarter — is the kind of print that travels fast. The stock reaction was reported between roughly 7% and 10% across after-hours coverage, with Barron's putting the pop at 8.3% and MarketWatch at 7.2%, as the result arrived alongside strong AMD and Arista Networks reports that together steadied the AI trade after the Nasdaq-100's slide into correction territory on Monday.

Chief executive Charles Liang credited the quarter to the company's shift into a total AI and IT data-center solutions provider, saying that transformation "continues to accelerate, delivering record revenue of $19.9 billion." Finance chief Mark Long told MarketWatch the company is building out a "high-quality customer base" that is fuelling the growth.

What to watch next

Two questions will decide whether the after-hours jump holds when regular trading resumes on Wednesday. The first is margin: growth this fast is coming from large-scale AI deployments, which carry thinner margins, and the fall from 17.5% gross margin in the June quarter to 12.7% is the main counterweight to the revenue story. The second is delivery: a $72 billion to $82 billion year requires the December quarter to land inside that $19.5 billion to $21.5 billion range. The company itself notes the figures are preliminary and unaudited, so final results could differ. For now, the print gives the AI trade fresh evidence of demand — reported here as news, not as a recommendation to buy, sell or hold any security.
