Super Micro posts $19.95 billion quarter and lifts its full-year outlook

Super Micro Computer just reported net sales of $19.95 billion for the first quarter of its fiscal 2027. That figure beat consensus estimates by $3.7 billion and was up 298% from the same quarter a year earlier.

The company also raised its full-year forecast and guided to another quarter of similar scale.

A quarter that outran three forecasts

The quarter ended September 30, 2026, and results were announced on November 3, 2026. Super Micro’s fiscal year runs through June 30, which is why the calendar and the fiscal labels look out of sync.

In August, management guided Q1 revenue to a range of $14.5 billion to $15.5 billion. On October 20, the company issued a preliminary update lifting that range to $18.5 billion to $19.5 billion. The final print then came in above the top of the revised range.

Earnings followed revenue higher. GAAP diluted earnings per share came in at $1.75, while non-GAAP diluted EPS reached $1.81.

Guidance moves up, margins move sideways

Super Micro now expects fiscal 2027 revenue of $72 billion to $82 billion. The prior forecast called for $65 billion to $72 billion, so the new floor sits at the old ceiling.

For the second quarter, the company is guiding to revenue between $19.5 billion and $21.5 billion.

The engine behind all of this is AI. Server and data center solutions for AI workloads made up 71% of Q1 revenue, and the company expects that share to land between 70% and 80% for the full fiscal year.

Margins tell a more modest story. Gross margin slipped on a sequential basis to 12.7%, or 12.8% on a non-GAAP basis. Even so, that came in above expectations of 12% to 12.5%.

The customer concentration question

One unnamed data center customer accounted for 44% of Q1 revenue. Two customers made up 49% and 17% of accounts receivable, meaning a large chunk of the money Super Micro is waiting to collect sits with a very short list of names.

Management flagged other potential speed bumps too. The company cited working capital constraints, along with possible limits from component availability and the readiness of power supply at customer sites.

The bull case on cash

An analyst writing on Seeking Alpha argued that investor worries about Super Micro’s cash balance and negative cash flows are misplaced. In that analyst’s view, the company’s core business momentum and its strong cash position limit downside risk. The author disclosed a long position in shares of SMCI and DELL.

Background: Super Micro’s place in the AI build-out

Super Micro designs and assembles the servers and data center systems that house accelerators, then sells those systems to cloud operators and large enterprises. The company has leaned on partnerships across the tech stack, including work with NVIDIA, Nutanix, and Nokia.

What this means

For investors, the report sharpens a trade-off that has defined Super Micro for a while. Growth is undeniable, with revenue up 298% year over year and full-year guidance lifted to $72 billion to $82 billion.

A single customer at 44% of revenue turns every quarter partly into a referendum on that one relationship. At 12.7% gross margin, Super Micro has limited room to absorb price pressure from buyers who know how much of its business they represent.

There are a few concrete things to watch from here. First, whether Q2 revenue lands inside the $19.5 billion to $21.5 billion range. Second, whether the AI share of revenue holds within management’s 70% to 80% expectation. Third, whether customer concentration eases as new buyers ramp, or tightens further as gigawatt-scale projects keep consolidating orders with a few names. Finally, component availability and power readiness at customer sites are factors Super Micro cannot fully control, and either one could slow the conversion of strong demand into reported revenue.
