How Does Supermicro Make Money?
Server and Storage Systems supplies 97% of revenue, so Supermicro's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Server and Storage Systems grew fastest (+50.2%) and Subsystems and Accessories slowest (-17.9%), so the revenue mix tilts toward Server and Storage Systems while that gap lasts.

What the Segment Figures Do Not Show
The rows above add up to 103% of Supermicro's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.
Where These Numbers Come From
Every figure on this page is a value Supermicro reported in the segment note and revenue disclosures of its Form 10-K filed August 28, 2025 (accession 0001375365-25-000027), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.
Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
