Officers
5
Three of the 5 officer records shown for OPTIBAU Holding GmbH are current appointments, filed with Handelsregister (Commercial Register). Jürgen Hellmann (appointed 2006-07-26) and Holger Niemeier (appointed 2006-07-26) both serve as Geschäftsführer (managing director); Nico Wendhausen (appointed 2021-09-21) serves as Officer. The remaining 2 records shown (Heinz-Hartmut Niemeier and Wolfgang Winkelmann) are former appointments that have since been resigned.
The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at OPTIBAU Holding 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
OPTIBAU Holding GmbH has no recorded parent company — it sits at the top of its own group structure, with 3 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 3 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. Three of the 3 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
