Group Structure
ALEXION PHARMACEUTICALS INC sits 1 level below its ultimate parent, ASTRAZENECA PLC, registered in United Kingdom. 19 subsidiaries are recorded beneath it, across 5 jurisdictions. The full chain up to ASTRAZENECA PLC is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by ALEXION PHARMACEUTICALS 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 19 subsidiaries span United States, Sweden, Belgium, France, 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 19 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
