Group Structure
QUEST DIAGNOSTICS NICHOLS INSTITUTE sits 1 level below its ultimate parent, Quest Diagnostics Incorporated, registered in United States. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to Quest Diagnostics Incorporated is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by QUEST DIAGNOSTICS NICHOLS INSTITUTE'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 1 subsidiary spans 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.
