argenx SE
argenx SE is an European Public Limited Liability Company registered in Netherlands under 24435214, and its current status with Netherlands Chamber of Commerce (KvK) is active. Its registered address on file is Amsterdam, Netherlands. 5 shareholders are on record for argenx SE, 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 Netherlands Chamber of Commerce (KvK) and was last updated on 8 September 2026.

Shareholders of argenx SE
Five shareholders are currently on record for argenx SE, reflecting the aandeelhoudersregister (shareholder register) maintained under Article 2:194 of the Dutch Civil Code rather than a public filing. The largest of these is VANGUARD SPECIALIZED FUNDS-Vanguard Health Care Fund, holding 5.2% — the largest recorded stake — followed by VANGUARD WORLD FUND-Vanguard International Growth Fund at 1.7%; the remaining 3 shareholders shown hold smaller stakes. 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.
