Why Ownership Structure Data Is Important

Knowing who owns a company is essential to understanding how businesses link and function worldwide. Our corporate hierarchy data allows you to follow connections between parent companies, subsidiaries, and shareholders, revealing control, organization, and potential risks within any global corporate group. Whether you are investigating GSK or another multinational, these insights aid compliance, market research, and better CRM management. With verified ownership records covering over 380 million companies around the globe, CompanyData.com gives you a clear view of corporate ownership across industries and countries.

How We Define Global, National, and Local Headquarters

At CompanyData.com, every company profile such as GSK is organized using our three-tier hierarchy model: Global, National, and Local headquarters. This structure clarifies how each entity fits inside the larger corporate group.

The three levels explained

  • Global Headquarter — GSK plc acts as the global headquarter for the GSK Group, based in London, United Kingdom. It holds the highest level in the group hierarchy.
  • National Headquarters — Country-level companies manage local business and report directly to the global parent. For example, GSK USA Inc., GSK Canada Ltd., and GSK India Ltd.
  • Local Headquarters — Regional subsidiaries handle operations like sales, marketing, manufacturing, and regulatory compliance within their own markets.

Each company gets a unique ID, enabling you to connect subsidiaries to their parent companies, trace ownership paths, and merge data into your systems.

How we show control

Control is based on ownership stakes. When a company holds more than 50% of another, we mark it as a controlled subsidiary. Our data highlights these majority-owned relationships to clearly represent corporate structures. This method gives a transparent view of complex groups like GSK’s and can be applied to any multinational business.

Why this is useful

This hierarchy helps identify who truly controls the GSK Group, simplifies compliance checks, and supports mergers, acquisitions, and risk management. By mapping each entity with verified ownership data, CompanyData.com lets you explore GSK’s corporate setup with confidence. With over 41 million companies linked in 200 countries and regions, our platform offers clarity for teams working with multinational groups.
