From Arista's reports to the SEC (latest: Form 10-Q, filed Nov 4, 2026). Quarters are named the way Arista names them. Fourth quarters aren't reported on their own: they are the full year minus the first nine months. A dash means the number isn't in the filings in a form we can check. Not investment advice.
