Knowing who owns and controls companies is essential to understanding how they operate globally. Our corporate hierarchy data lets you follow the links between parent companies, subsidiaries, and shareholders, showing you control and structure inside any multinational group. Whether you work with Rio Tinto or other global corporations, this valuable insight aids in compliance, market research, and better CRM management. With verified ownership information on more than 380 million companies worldwide, CompanyData.com gives you a clear picture of who owns who across countries and industries.
At CompanyData.com, the corporate structure of each company — like Rio Tinto — is shown through our three-level model: Global, National, and Local headquarters. This system reveals how each part fits into the larger group.
Every entity has a unique ID, making it easy to trace ownership paths, connect subsidiaries to parent companies, and integrate this data into your own systems.
Majority control is the key factor. If a parent company owns more than 50% of another company, that entity is considered a controlled subsidiary. We focus on this majority ownership to present clear and accurate corporate family trees. This method reveals complex ownership structures such as Rio Tinto’s and applies to all large global groups.
This approach identifies the main decision-makers inside Rio Tinto, eases compliance reviews, and supports risk evaluation or mergers and acquisitions. By linking all entities with verified ownership data, CompanyData.com helps users understand Rio Tinto’s full corporate network. With over 322 subsidiaries spread across 38 countries including key locations like the United States (US), Canada (Canada), Australia (Australia), United Kingdom (UK), and Singapore (Singapore), our platform offers a detailed overview for your corporate insights.
