- opta data IT GmbH (Germany)
- opta data Finance GmbH (Germany)
- opta data Service GmbH (Germany)
Data availability
Those 3 subsidiaries span Germany jurisdiction, though this list should not be read as complete — subsidiaries only become visible here where shareholder data has actually been filed with a register, so holdings in jurisdictions without that filing simply won't appear. Three of the 3 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
