Group Structure

PTW – Freiburg Physikalisch-Technische Werkstätten Dr. Pychlau GmbH has no recorded parent company — it sits at the top of its own group structure, with 7 subsidiaries recorded beneath it across 7 jurisdictions. 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 7 subsidiaries span Germany, Hong Kong, Russia, United Kingdom, Spain, United States, and 1 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.
