F5, Inc.
A maker of software and hardware that keeps websites and apps fast, secure, and online, F5 sells products like BIG-IP, NGINX, and Distributed Cloud Services to businesses, governments, and service providers around the world. It was founded in Seattle in 1996 as F5 Labs by Jeffrey Hussey, launching its flagship BIG-IP load balancer in 1997. The name comes from the Fujita tornado scale—F5 being the most powerful category—meant to evoke the sheer force of traffic its devices could handle.

Select a row to see that insider’s individual transactions. Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
Net open-market activity over the last 5 years: -347.5K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
