Group Structure
1&1 Telecommunication SE sits 2 levels below its ultimate parent, United Internet AG, registered in Germany. 6 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to United Internet AG is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by 1&1 Telecommunication SE's own shareholder record. 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 6 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. One of the 6 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
