F5, INC.
F5, INC. is a registered legal entity registered in United States under 601692492, and its current status with Washington Secretary of State is active. The company was incorporated on 26 February 1996 and lists its registered address as SEATTLE, United States. 5 shareholders are on record for F5, INC., and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Washington Secretary of State and was last updated on 22 September 2026.

Shareholders
5
Five shareholders are currently on record for F5, INC., reflecting the stock ledger maintained under state corporate law (e.g. §219 of the Delaware General Corporation Law) rather than a public filing.
The largest of these is Vanguard Group Inc, holding 17.5% — the largest recorded stake — followed by UBS Group AG at 2.4%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 6 shareholders in total, though only the top 5 by holding are shown in this view.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers
5
The Governingperson of F5, INC. on record is FRANK PELZER; 5 officers are shown here, filed with Washington Secretary of State.
The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at F5, INC. sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
F5, INC. has no recorded parent company — it sits at the top of its own group structure, with 19 subsidiaries recorded beneath it across 12 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 19 subsidiaries span United States, Belgium, Spain, Switzerland, Saudi Arabia, Indonesia, and 6 more jurisdictions, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Two of the 19 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
