How these relationships were recorded
QUEST DIAGNOSTICS INCORPORATED has no recorded parent company — it sits at the top of its own group structure, with 78 subsidiaries recorded beneath it across 5 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 78 subsidiaries span United States, Finland, Mexico, India, Brazil 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. 10 of the 78 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
