sema Systemtechnik GmbH
sema Systemtechnik GmbH is a Private limited company (Ltd.) registered in Germany under HRB 8365 Bad Oeynhausen, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Bünde, Germany. 3 shareholders are on record for sema Systemtechnik 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 16 October 2026.

Shareholders
3

The largest of these is sema Systemtechnik GmbH & Co. KG, holding 50.3% — a majority holding — followed by sema Systemtechnik GmbH & Co. KG at 26.5%; the remaining 1 shareholder shown holds smaller stakes.

Officers
5
Three of the 5 officer records shown for sema Systemtechnik GmbH are current appointments, filed with Handelsregister (Commercial Register). Volker Wörmann (appointed 2010-02-16) and Michael Braetz (appointed 2010-02-16) both serve as Geschäftsführer (managing director); Jens Grewatsch (appointed 2022-02-16) serves as Officer. The remaining 2 records shown (Heinz-Gerhard Ellermann and Hans-Jürgen Unger) 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 sema Systemtechnik 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
sema Systemtechnik GmbH sits 2 levels below its ultimate parent, PHOENIX Beteiligungs-GmbH, registered in Germany. 1 subsidiary is recorded beneath it, across 2 jurisdictions. The full chain up to PHOENIX Beteiligungs-GmbH is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by sema Systemtechnik 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, Norway 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 1 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
