Why Understanding Corporate Structure of ConocoPhillips Is Important

Knowing the ownership structure helps you understand how companies operate and connect worldwide. Our corporate hierarchy data allows you to follow the relationships between parent companies, subsidiaries, and shareholders, showing control, organization, and risks within any global group. Whether you’re studying ConocoPhillips or other multinational firms, this insight supports compliance monitoring, industry research, and improved CRM management. With verified ownership details covering millions of companies globally, CompanyData.com gives a clear picture of who owns whom across sectors and borders.

How ConocoPhillips' Global and Local Structure Is Mapped

At CompanyData.com, we structure each corporation like ConocoPhillips into three main levels: Global, National, and Local headquarters. This method shows the position of every entity within its corporate family.

The three main levels

  • Global Headquarter — ConocoPhillips is the global headquarter, managing the entire group from its office in the United States (US).
  • National Headquarters — Country-specific entities handle operations and report to the global parent company. Examples include ConocoPhillips Canada Ltd., ConocoPhillips UK Ltd., and ConocoPhillips Netherlands B.V.
  • Local Headquarters — Regional offices or subsidiaries operate production sites, refineries, and business units, maintaining compliance and local market management.

Each firm is assigned a unique ID, allowing you to connect subsidiaries to the parent structure, trace ownership routes, and integrate this data with your systems.

Showing control in ownership

Ownership greater than 50% defines control under our model. Companies with a majority stake in another firm are shown as controlled subsidiaries. Our dataset highlights these majority-owned connections to clearly outline corporate hierarchies. This approach applies to complex structures like ConocoPhillips’ and other multinational corporations.

Why this structure is useful

This framework helps identify key decision makers within ConocoPhillips, facilitates compliance reviews, and supports merger, acquisition, or risk evaluations. Through verified ownership data, CompanyData.com enables users to understand ConocoPhillips’ corporate setup with confidence. Covering over 686 entities in more than 25 countries, including the USA (567 subsidiaries), Norway (64), Canada (15), and Netherlands (6), our platform delivers transparent business ownership data to global teams navigating complex corporate networks.
