ATH Altonaer-Technologie-Holding GmbH
ATH Altonaer-Technologie-Holding GmbH is a Private limited company (Ltd.) registered in Germany under HRB 26741 Hamburg, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Hamburg, Germany. 1 shareholder is on record for ATH Altonaer-Technologie-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 19 October 2026.

Officers
3
Two of the 3 officer records shown for ATH Altonaer-Technologie-Holding GmbH are current appointments, filed with Handelsregister (Commercial Register). Markus Plocher and Markus Bernd Waterkamp both serve as Geschäftsführer (managing director). The remaining 1 record shown (Bernward Josef Kurpisch) is a former appointment that has since been resigned.
Management authority at ATH Altonaer-Technologie-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
ATH Altonaer-Technologie-Holding GmbH sits 1 level below its ultimate parent, Burkhard Meyer Stiftung, registered in Germany. 9 subsidiaries are recorded beneath it, across 1 jurisdiction. The full chain up to Burkhard Meyer Stiftung is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by ATH Altonaer-Technologie-Holding 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 9 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. Two of the 9 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
