PORR AG
PORR AG is a Public Limited Company registered in Austria under FN 034853F, and its current status with Austrian Business Register (Firmenbuch) is active. The company was incorporated on 30 June 1993 and lists its registered address as Wien, Austria. 5 shareholders are on record for PORR AG, 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 Austrian Business Register (Firmenbuch) and was last updated on 13 October 2026.

Shareholders
5
Five shareholders are currently on record for PORR AG, based on voting-rights notifications filed under Austria's capital-markets disclosure rules.
The largest of these is Vanguard International Stock Index-Total Intl Stock Indx, holding 24.1% — the largest recorded stake — followed by Avantis International Small Cap Value ETF at 12.5%; the remaining 3 shareholders shown hold smaller stakes.
The register reports 10 shareholders in total, though only the top 5 by holding are shown in this view.
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.

Officers
5
The Managing Director Of Business Unit 2 – Cee/see of PORR AG currently on record is Franz Scheibenecker; five officers are currently on record for PORR AG, filed with Austrian Business Register (Firmenbuch).
The register reports 19 officers in total, including past appointments, though only the 5 most relevant records are shown here.
Management authority at PORR AG sits with these individuals, not with shareholders, who are covered separately and hold ownership rather than control.
The source filing doesn't specify representation authority — whether officers can act individually or must sign jointly to bind the company — so that detail isn't available here.
Group Structure
PORR AG has no recorded parent company — it sits at the top of its own group structure, with 22 subsidiaries recorded beneath it across 5 jurisdictions. Each of these downward relationships is derived rather than filed: resolved by matching entities across the registry network, not stated directly in a single document.
Those 22 subsidiaries span Austria, Belgium, Switzerland, Qatar, Germany 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. Seven of the 22 go a level deeper still, with their own further subsidiaries recorded beneath them — additional ownership layers this view doesn't expand.
