Corporate structure overview

Understanding SK Hynix's Global Network

Knowing the ownership structure of a company is important to understand how it operates worldwide. Our corporate hierarchy data uncovers the links between parent companies, subsidiaries, and shareholders, showing control and organization within global groups. With SK Hynix, a leading semiconductor company, this insight supports compliance review, business research, and better CRM management. CompanyData.com tracks verified ownership details across millions of firms globally to help you see who controls whom, across industries and borders.

How SK Hynix's Headquarters and Subsidiaries Are Organized

At CompanyData.com, SK Hynix is mapped using our three-level corporate hierarchy model: Global, National, and Local headquarters. This setup helps show how each part of the company fits into the global family.

The three headquarters levels

  • Global Headquarter — SK Hynix Inc. serves as the global headquarter, based in Seoul, South Korea. It is the top entity that controls the entire group.
  • National Headquarters — These are the country-level companies that manage operations locally and report directly to the global headquarter. Examples include SK Hynix USA Inc., SK Hynix China Ltd., and SK Hynix Japan K.K.
  • Local Headquarters — These regional subsidiaries run local offices, production sites, and support SK Hynix’s business activities in various markets, ensuring compliance and brand presence.

Each entity receives its own unique ID to link subsidiaries with parent companies, trace ownership, and allow integration with other data systems.

How control is represented

Subsidiaries are marked as controlled when SK Hynix owns more than 50% of the shares. Our data highlights these majority control relations, so you get a clear picture of SK Hynix’s global group structure. This method works well for any multinational company with complex ownership.

Why this is useful

This structured data identifies who holds decision-making power in SK Hynix, helps with compliance checks and due diligence, and supports risk and merger assessments. With SK Hynix’s network spanning countries including China (27 subsidiaries), South Korea (12 subsidiaries), the United States (14 subsidiaries), Japan (5 subsidiaries), Germany (2 subsidiaries), and more, CompanyData.com offers a complete view of their global reach.
