HOB Holding GmbH is a Private limited company (Ltd.) registered in Germany under HRB 73575 Köln, and its current status with Handelsregister (Commercial Register) is intermediate. Its registered address on file is Bergheim, Germany. 3 shareholders are on record for HOB Holding GmbH, and since every one of them is a company rather than an individual, this particular filing does not on its own establish an ultimate beneficial owner (UBO) — identifying one would mean tracing the ownership of each shareholding company in turn. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 9 October 2026.

Shareholders

3

Three shareholders are currently on record for HOB Holding GmbH, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG.

The largest of these is Oliver Kau UG (haftungsbeschränkt) & Co. KG, holding 33.3% — the largest recorded stake — followed by Holger Kau UG (haftungsbeschränkt) & Co. KG at 33.3%; the remaining 1 shareholder shown holds smaller stakes.

Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.

Officers

5

The Geschäftsführer (managing director) of HOB Holding GmbH currently on record is Björn Siewert; five officers are currently on record for HOB Holding GmbH, filed with Handelsregister (Commercial Register).

The register reports 6 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Management authority at HOB 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

HOB Holding GmbH has no recorded parent company — it sits at the top of its own group structure, with 6 subsidiaries recorded beneath it across 2 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 6 subsidiaries span Germany, Netherlands 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 6 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
