Management authority at Cortex Biophysik 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
Cortex Biophysik GmbH sits 2 levels below its ultimate parent, HWN Holding GmbH & Co. KG, registered in Germany. 1 subsidiary is recorded beneath it, across 2 jurisdictions. The full chain up to HWN Holding GmbH & Co. KG is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Cortex Biophysik GmbH'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 1 subsidiary spans Germany, Ukraine 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.
