Management authority at ONI-Wärmetrafo GmbH sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
ONI-Wärmetrafo GmbH has no recorded parent company — it sits at the top of its own group structure, with 3 subsidiaries recorded beneath it across 3 jurisdictions. 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 3 subsidiaries span Germany, Norway, China 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 3 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
