Porr GmbH
Porr GmbH is a Private limited company (Ltd.) registered in Austria under FN 254811Y, and its current status with Austrian Business Register (Firmenbuch) is inactive. The company was incorporated on 4 November 2004 and lists its registered address as Wien, Austria. 5 shareholders are on record for Porr 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.
