Group Structure
VIRGINIA MASON MEDICAL CENTER sits 1 level below its ultimate parent, Commonspirit Health, registered in United States. 4 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Commonspirit Health is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by VIRGINIA MASON MEDICAL CENTER'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 4 subsidiaries span United States jurisdiction, 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 4 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
