Those 25 subsidiaries span Ireland, Greece, Switzerland, New Zealand, Austria, Norway, and 15 more 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. One of the 25 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
