Data availability
Those 6 subsidiaries span Germany, Belarus, United States jurisdictions, 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. Two of the 6 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
