Günter Sievers Maschinenbau GmbH
Günter Sievers Maschinenbau GmbH is a Private limited company (Ltd.) registered in Germany under HRB 52188 Hannover, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Hemmingen, Germany. 2 shareholders are on record for Günter Sievers Maschinenbau 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 13 October 2026.

Shareholders
2
Two shareholders are currently on record for Günter Sievers Maschinenbau GmbH, held on the Gesellschafterliste (shareholder list), filed under §40 of the GmbHG.
The largest of these is GSMG Beteiligungs GmbH & Co.KG, holding 70% — a majority holding — followed by Wilhem Herm. Müller GmbH & Co.KG at 30%.
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
3
Three officers are currently on record for Günter Sievers Maschinenbau GmbH, filed with Handelsregister (Commercial Register). Martin Günther (appointed 2006-02-17) serves as Geschäftsführer (managing director); Henry Jonschker (appointed 2009-07-02) and Joachim Lammers (appointed 2019-08-08) both serve as Officer.
Management authority at Günter Sievers Maschinenbau 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
Günter Sievers Maschinenbau GmbH sits 1 level below its ultimate parent, GSMG Beteiligungs-GmbH & Co. KG, registered in Germany. 1 subsidiary is recorded beneath it, across 1 jurisdiction. The full chain up to GSMG Beteiligungs-GmbH & Co. KG is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Günter Sievers Maschinenbau 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 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.
