Siteco GmbH
Siteco GmbH is a Private limited company (Ltd.) registered in Germany under HRB 27821 Traunstein, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Traunreut, Germany. 1 shareholder is on record for Siteco 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 2 October 2026.

1
One shareholder is currently on record for Siteco GmbH, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG.

Officers
5
Four of the 5 officer records shown for Siteco GmbH are current appointments, filed with Handelsregister (Commercial Register). Andreas Willi Frank (appointed 2020-11-30), Ralph Christian Hesse (appointed 2023-03-11) and Daniel Fischer (appointed 2023-06-12) all serve as Geschäftsführer (managing director); Andreas Deibl (appointed 2022-11-29) serves as Officer. The record also shows 1 earlier, since-resigned appointment held by an officer who currently serves.
The register reports 16 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at Siteco 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
Siteco GmbH sits 1 level below its ultimate parent, Stern Stewart Industries I GmbH, registered in Germany. 16 subsidiaries are recorded beneath it, across 13 jurisdictions. Immediately above Siteco GmbH is Stern Stewart Industries I GmbH, holding 100% as filed in Siteco GmbH's own shareholder record with Handelsregister (Commercial Register). 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 16 subsidiaries span Germany, Poland, United Kingdom, Spain, Austria, Switzerland, and 7 more 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 16 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
