Why Ownership Structure Data Matters

Understanding ownership is key to seeing how companies connect and operate. Our corporate hierarchy data helps you trace relationships between parent companies, subsidiaries, and shareholders, showing control, structure, and risk inside any global group. Whether you’re analysing McKesson or another large multinational, this type of insight supports compliance checks, market research, and better CRM data management. With verified ownership records covering millions of companies worldwide, CompanyData.com gives a clear view of who owns whom across industries and countries.

How We Track Global, National, and Local Headquarters

At CompanyData.com, every company profile – such as McKesson – is organised using a three-level hierarchy: Global, National, and Local headquarters. This setup shows how each entity fits into the larger corporate family.

Three levels explained

  • Global Headquarters — McKesson Corporation serves as the global headquarter of the McKesson Group, located in the United States. This top entity oversees all other parts of the group.
  • National Headquarters — Country-specific subsidiaries manage operations locally and report to the global parent. Examples include McKesson Canada Corporation and McKesson UK Ltd.
  • Local Headquarters — These regional subsidiaries manage local distribution centers, pharmacies, or service units within their markets, ensuring local regulatory compliance and brand presence.

Each entity has a unique ID, helping you connect subsidiaries to parent companies, follow ownership paths, and integrate the data with your systems.

How ownership and control are shown

Control is based on ownership levels. When one company owns more than 50% of another, we classify it as a controlled subsidiary. Our data focuses on these majority-owned links to show clear corporate structures. This method gives a transparent view of complex ownership like McKesson’s and applies to any large multinational.

Why this information is important

This model helps show who the real decision-makers are within the McKesson Group, simplifies compliance and risk assessment, and aids mergers and acquisitions analysis. By mapping all entities with verified ownership data, CompanyData.com lets users explore McKesson’s corporate hierarchy with confidence. With data on more than 1,300 related companies in 8 countries and regions, including the USA, Canada, and UK, our platform brings clarity to global corporate structures.
