Knowing the ownership details helps you see how companies are linked and operate worldwide. Our corporate hierarchy data makes it easy to track the connections between parent companies, subsidiaries, and shareholders. This reveals the control, structure, and risk inside any global business group. Whether you’re studying Entergy or another multinational, having this insight helps with compliance checks, market research, and better CRM data management. With verified ownership records covering millions of companies worldwide, CompanyData.com shows you who owns who across industries and borders.

How We Track Entergy’s Global and Local Headquarters

At CompanyData.com, each company profile – like Entergy – is organized using a three-level structure: Global, National, and Local headquarters. This setup helps show how every part fits into the overall corporate family.

The three levels we follow

  • Global Headquarters — Entergy Services, Inc. acts as the global headquarter of the Entergy Group, overseeing all other entities within the group. Its principal operations are centered in the US (country code 1).
  • National Headquarters — These manage operations for specific countries or regions. For Entergy, this includes main entities in the United States, where all 290 known subsidiaries operate under the country code 1.
  • Local Headquarters — Local subsidiaries look after day-to-day activities, power plants, and service regions, ensuring compliance and brand presence in various local markets.

Every entity is given a unique ID to easily connect subsidiaries with their parent companies, map ownership, and integrate this data with your systems.

Control and ownership explained

Control is based on ownership percentage. When one company owns over 50% of another, it’s considered a controlled subsidiary. Our data focuses on these majority-owned relationships to clearly map corporate chains. This method reveals detailed corporate structures like Entergy’s and can be applied to other global groups.

The benefit of this data

This structured view helps identify key decision makers within the Entergy Group, supports compliance and risk analysis, and aids growth planning. By mapping all entities with verified ownership, CompanyData.com allows you to confidently explore Entergy’s corporate makeup. With data covering more than 41 million companies in over 200 countries and jurisdictions, our service offers valuable clarity for international business teams working in complex networks.
