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
H.C. Starck Tungsten GmbH sits 4 levels below its ultimate parent, MITSUBISHI MATERIALS CORPORATION, registered in Japan. 3 subsidiaries are recorded beneath it, across 4 jurisdictions. The full chain up to MITSUBISHI MATERIALS CORPORATION is derived by walking shareholder filings across jurisdictions; no link in it is independently corroborated by H.C. Starck Tungsten 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 3 subsidiaries span Germany, China, Japan, 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.
