Understanding ownership helps to see how companies are linked and operate worldwide. Our corporate hierarchy data allows you to follow the connections between parent companies, subsidiaries, and shareholders, showing control, structure, and risks inside any global group. Whether looking at Sempra or other multinational companies, this data assists in compliance checks, market research, and better CRM data management. With verified ownership records covering over 380 million companies, CompanyData.com offers a clear picture of corporate relationships across industries and countries.
At CompanyData.com, each company profile – such as Sempra – is structured using our three-level hierarchy system: Global, National, and Local headquarters. This mapping shows how every entity fits into the full corporate family.
Each company is assigned a unique ID, making it easy to connect subsidiaries back to their parent firms, follow ownership lines, and integrate these insights into your systems.
Control is defined by ownership share. When a company holds over 50% of another, it is classified as a controlled subsidiary within our data. We focus on these majority control links to clearly visualize corporate hierarchies. This method helps map complex ownership layers like those of Sempra and can be applied across any global company.
This structure identifies who has real authority in the Sempra Group, streamlines compliance verifications, and supports mergers & acquisitions or risk analysis. By linking entities through verified ownership data, CompanyData.com helps users clearly understand how Sempra and other large multinational companies are organized. With more than 41 million companies connected across 200 countries and jurisdictions, our platform brings transparency to complex international corporate networks.
