Adtran Networks SE
Adtran Networks SE is a registered legal entity registered in Germany under HRB 508155 Jena, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Meiningen OT Dreißigacker, Germany. 5 shareholders are on record for Adtran Networks SE, 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 23 September 2026.

Christoph Glingener (appointed 2007-06-11) and Timothy Santo both serve as Aufsichtsratsmitglied (board member).
