PORR CEO Karl-Heinz Strauss: “PORR delivered an outstanding performance in 2024, and in doing so earned the trust of investors and analysts even in a challenging environment for the global economy. We’re very proud of this achievement – it shows that our successes in the construction industry are being recognised by the capital market as well”. The first trading in the ATX takes place on Monday, 22 September.  

Over the past 12 months, PORR has more than doubled its share price: An increase of +118% between 1 September 2024 and 31 August 2025 was a key driver of the company’s ascension. The trading volume of PORR shares on the Vienna Stock Exchange quadrupled during the same period. In June 2025, trading gained additional momentum: The free float rose to 52.6% as PORR sold 1,703,674 treasury shares, while a further 1,175,000 shares held by SuP Beteiligungs GmbH were offered on the market via a private placement. This attracted considerable interest from international institutional investors, boosting the share’s liquidity even further.

Strengthening stakeholder communication

Strauss sees the enhanced communication with stakeholders as being one of the key success factors: “Conferences, roadshows and targeted engagement through social media are a must nowadays, especially when it comes to reaching retail investors. Our shareholders are highly knowledgeable decision-makers who require up-to-date information around the clock”.

PORR’s entry into the ATX marks another milestone in its long success story on the Austrian capital market: On 8 April 1869, the year it was founded, “Allgemeine Österreichische Baugesellschaft” was first listed on the Vienna Stock Exchange. This means that PORR is the oldest share still traded there today.
