How these relationships were recorded
100-SIO SYNERGIA S.A. has no recorded parent company — it sits at the top of its own group structure, with 15 subsidiaries recorded beneath it across 1 jurisdiction. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 15 subsidiaries span Poland 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.
