Altech Advanced Materials AG is a Join Stock Company registered in Germany under HRB 118874 Frankfurt am Main, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Heidelberg, Germany. As a Join Stock Company, Altech Advanced Materials AG files no Gesellschafterliste, so no shareholder list is available from the German commercial register — ownership of a listed Aktiengesellschaft is disclosed instead through WpHG voting-rights notifications above statutory thresholds. No beneficial owner record is shown for Altech Advanced Materials AG, as access to the German Transparenzregister is restricted to obliged entities and legitimate-interest applicants following the November 2022 CJEU ruling. This profile is sourced directly from Handelsregister (Commercial Register) and was last updated on 25 September 2026.
