Phytron GmbH
Phytron GmbH is a Private limited company (Ltd.) registered in Germany under HRB 205987 München, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Maisach, Germany. 2 shareholders are on record for Phytron GmbH, 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 17 October 2026.

Shareholders

The largest of these is STEMAS AG, holding 60% — a majority holding — followed by Robert Stößer GmbH at 40%.
Because every shareholder shown is a company rather than an individual, the ownership chain continues above this level, and no beneficial owner can be established from this filing alone.
