PORR

What PORR does

PORR is a Vienna-headquartered construction firm founded in 1869, operating as a general and total contractor for building construction, civil engineering, infrastructure, environmental engineering, and specialized construction (tunneling, railway, waterproofing, timber, steel) across seven European country markets: Austria, Germany, Switzerland, Czech Republic, Poland, Slovakia, and Romania. With an average of 19,939 employees in Q1 2026 and a record order backlog exceeding EUR 10 billion (60.6% civil engineering, 33.6% building construction, 7.5% residential under the PORR Living sub-brand), the company serves public-sector clients (ASFINAG, ÖBB-Infrastruktur, City of Vienna) and private enterprise (Bayer, Panattoni, Styria Media, Raiffeisenlandesbank Kärnten, FH Campus Wien).

The company executes projects through dedicated operating subsidiaries that concentrate specialized capability: pde Integrale Planung (BIM and integral design), IAT GmbH (waterproofing and sealing), PPE/Pharmaplan (pharmaceutical facility planning, credited on Bayer's ISPE FOYA-winning SOLIDA-1 plant), Bautech Labor (accredited materials testing), PORR Umwelttechnik (environmental remediation), and Nägele Hoch- und Tiefbau (Vorarlberg regional coverage). Proprietary technical differentiators include low-emission concrete (CEM II/C binder, e.g., 4,200 t CO2e saved on the ZBG Aspern vocational school), BIM-based 5D planning, and IAT's bridge and tunnel sealing systems.

PORR monetizes through project-based construction services as general and total contractor, with revenue recognized on milestone/progress basis and pricing set via competitive tendering. The business model is complemented by acquisitions that extend capability (51% of drylining specialist rhtb: in May 2026; 50% of precast concrete specialist Moderna Construction in June 2026) and by digital platforms such as the PORR Maschinenbörse equipment marketplace and the World of PORR digital magazine. Q1 2026 financials show EUR 1,245.5M revenue, EUR 1,300M production output, EUR 1,765M order intake (+14.7% YoY), EUR 66.8M EBITDA, and EUR 14.3M EBIT at a 1.1% margin, with Austria accounting for 45.2% of group production.
