STEAG GmbH
STEAG GmbH is a Private limited company (Ltd.) registered in Germany under HRB 19649 Essen, and its current status with Handelsregister (Commercial Register) is active. Its registered address on file is Essen, Germany. 3 shareholders are on record for STEAG 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 30 September 2026.

The largest of these is STEAG Group GmbH, holding 49% — the largest recorded stake — followed by STEAG Group GmbH at 45.9%; the remaining 1 shareholder shown holds smaller stakes.

Those 3 subsidiaries span Germany, Turkey 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. Two of the 3 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
