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 entities, subsidiaries, and shareholders, revealing control, structure, and risk within any global group. Whether you’re analysing Northrop Grumman or another multinational, this level of insight supports compliance checks, market research, and smarter CRM data management. With verified ownership records covering more than 380 million companies worldwide, CompanyData.com delivers a clear view of who owns who across industries and borders.

How We Map Global, National, and Local Headquarters

At CompanyData.com, each company profile – like Northrop Grumman – is mapped using our three-level hierarchy model: Global, National, and Local headquarters. This structure reveals how every entity fits into its wider corporate family.

Three levels we use

  • Global Headquarter — Northrop Grumman Corporation serves as the global headquarter of the Northrop Grumman Group, located at their main office in Falls Church, Virginia, United States. It sits above all other entities in the group.
  • National Headquarters — Country-level entities manage operations and report to the global parent. Examples include Northrop Grumman USA Inc., Northrop Grumman Canada Ltd., and other regional subsidiaries.
  • Local Headquarters — Regional subsidiaries oversee manufacturing plants, service units, and project divisions within their own markets, maintaining local compliance and operational control.

Each entity is assigned a unique ID, allowing you to link subsidiaries to parent groups, trace ownership paths, and integrate the data across your own systems.

How control is shown

Control is determined by ownership. When a company owns more than fifty percent of another, we classify it as a controlled subsidiary. Our data focuses on these majority-controlled relationships to clearly represent corporate hierarchies. This approach provides a transparent view of complex ownership networks such as Northrop Grumman’s and can be applied to any multinational group.

Why this matters

This model helps identify the real decision makers within the Northrop Grumman Group, simplifies compliance checks, and supports M&A or risk analysis. By mapping each entity with verified ownership data, CompanyData.com enables users to navigate Northrop Grumman’s corporate hierarchy confidently and see how global companies are structured. With more than 41 million companies linked across 200 countries and jurisdictions, our platform delivers clarity and transparency to international teams working with complex corporate networks.
