Knowing who owns and controls companies is essential for understanding how they operate globally. Our corporate hierarchy data lets you follow the connections between parent companies, subsidiaries, and shareholders. This data shows the structure, control, and risks inside any multinational group. Whether you are researching Exelon Corporation or another large company, this level of insight helps support compliance checks, market research, and better CRM data management. CompanyData.com offers verified ownership details on millions of companies worldwide, providing a clear picture of global corporate ownership across industries and borders.
At CompanyData.com, each company, including Exelon Corporation, is mapped through a three-tier headquarters model: Global, National, and Local. This clarifies how every entity fits within the broader corporate structure.
Every entity is given a unique identifier, making it easy to link subsidiaries to parent companies, trace ownership paths, and integrate data into your systems.
Control is based on ownership stakes. When an entity owns over 50% of another, it’s considered a controlled subsidiary.

This method offers clear views of complex corporate networks, such as Exelon’s, and can be applied to any multinational firm.
