Ritz Instrument Transformers GmbH is a Private limited company (Ltd.) registered in Germany under HRB 102486 Hamburg, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Hamburg, Germany. 2 shareholders are on record for Ritz Instrument Transformers 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 6 October 2026.

The Geschäftsführer (managing director) of Ritz Instrument Transformers GmbH currently on record is Ingmar Grambow; five officers are currently on record for Ritz Instrument Transformers GmbH, filed with Handelsregister (Commercial Register).

The register reports 19 officers in total, including past appointments, though only the 5 most relevant records are shown here.

Group Structure

Ritz Instrument Transformers GmbH sits 3 levels below its ultimate parent, Dr. Hans Ritz und Liselotte Ritz Stiftung, registered in Germany. 4 subsidiaries are recorded beneath it, across 4 jurisdictions. The full chain up to Dr. Hans Ritz und Liselotte Ritz Stiftung is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by Ritz Instrument Transformers 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 4 subsidiaries span Germany, Sweden, Norway, United States 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 4 go a level deeper still, with its own further subsidiaries recorded beneath it — additional ownership layers this view doesn't expand.
