Group Structure

Group structure of IBU-tec advanced materials AG

IBU-tec advanced materials AG has no recorded parent company — it sits at the top of its own group structure, with 2 subsidiaries recorded beneath it across 1 jurisdiction. 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.

  • BNT Chemicals GmbH (Germany)
  • IBUvolt battery materials GmbH (Germany)

Data availability

Those 2 subsidiaries span 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.
