Method and sources
Companies among the 100 we cover that F5 names as competitors in its latest annual report (10-K or 20-F), counted by Hollsteen. A company counts only when the quoted sentence itself names it and speaks of competition; hedged sentences (“some of which are competitors”) and quarterly reports are left out.
Competitors outside our coverage are not listed, so the list is not complete. Sentences are quoted exactly as filed.
