Why Ownership Structure Data is Important

Understanding ownership is essential to seeing how companies connect and operate. Our corporate hierarchy data helps you track relationships between parent companies, subsidiaries, and shareholders, showing control, structure, and risk within any global group. Whether you are studying Siemens or another multinational, this insight supports compliance checks, market research, and improved CRM data management. With verified ownership records covering millions of companies worldwide, CompanyData.com gives a clear picture of who owns who across industries and borders.

How We Organize Global, National, and Local Headquarters

At CompanyData.com, each company profile – like Siemens – is organized using our three-level structure: Global, National, and Local headquarters. This framework reveals how every entity fits into the larger corporate group.

Three levels explained

  • Global Headquarter — Siemens AG acts as the global headquarter of the Siemens Group, located in Munich, Germany. It sits at the top of all other company parts worldwide.
  • National Headquarters — Country-level entities manage operations and report to the global parent. Examples include Siemens USA Inc., Siemens Canada Ltd., and Siemens Netherlands B.V.
  • Local Headquarters — Regional subsidiaries handle sites, plants, and operations within their market, maintaining local compliance and brand presence.

Each company is given a unique ID, which lets you link subsidiaries to parent groups, follow ownership paths, and use the data within your systems.

How control is identified

Control is based on ownership. When one company owns more than fifty percent of another, it is classified as a controlled subsidiary. Our data highlights these majority-owned connections to clearly show corporate hierarchies. This method gives a transparent view of complex ownership networks like Siemens’ and can apply to any multinational corporation.

Why this information is useful

This model helps pinpoint the main decision makers in the Siemens Group, supports compliance checks, and aids in mergers & acquisitions or risk evaluations. By mapping every entity with verified ownership details, CompanyData.com lets users understand Siemens’ corporate structure confidently. With more than 41 million companies linked across 200 countries and jurisdictions, our platform offers clarity and transparency for international teams handling complex corporate groups.
