AMGEN INC.
AMGEN INC. is a registered legal entity registered in United States under 601170854, and its current status with Washington Secretary of State is active. The company was incorporated on 2 October 1989 and lists its registered address as THOUSAND OAKS, United States. 2 shareholders are on record for AMGEN 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
2
Two shareholders are currently on record for AMGEN 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 16.9% — the largest recorded stake — followed by Fidelity Concord Street Trust-Fidelity 500 Index Fund at 2.1%.
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.

| Fidelity Concord Street Trust-Fidelity 500 Index Fund | 2.1% | Washington Secretary of State |
Officers
5
The Governingperson of AMGEN INC. on record is R. SANDERS WILLIAMS; 5 officers are shown here, filed with Washington Secretary of State.
The register reports 14 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at AMGEN 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
AMGEN INC. sits 1 level below its ultimate parent, Amgen Inc., registered in United States. 3 subsidiaries are recorded beneath it, across 4 jurisdictions. The full chain up to Amgen Inc. is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by AMGEN INC.'s own shareholder record. 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 3 subsidiaries span United States, Hong Kong, Austria, Mexico 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. One of the 3 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
