Who are Synopsys’s biggest customers?
One Customer: 13% of FY2024 revenue
stale FY2024 is the latest fiscal year with a 10% customer fact in the SEC data; the latest fiscal year with reported revenue is FY2025, for which no 10% customer is in the data yet.
The filing does not name this customer. Hollsteen never guesses names.
“One customer, including its subsidiaries, accounted for 12.6%, and 13.5% of our consolidated revenue in fiscal 2024 and 2023, respectively.”

Numbers, method and sources
Share of revenue per customer as tagged in the filing’s XBRL (ConcentrationRiskPercentage, benchmark revenue). US GAAP requires disclosure only for customers with at least 10% of revenue; a year without a customer means below 10% or not disclosed. Labels like “Customer A” are the filer’s own; the same label is not guaranteed to be the same customer every year.
