How F5 makes money

Each fiscal year from SEC filings. Percentages are share of revenue, so the green profit nodes read directly as gross / operating / net margin. Line items a company doesn't break out are derived from their siblings so the flows balance; small residuals show as “Other.” For informational purposes only.
