Austrian construction group PORR saw its shares tumble roughly 9% on Friday, constituting the steepest single‑day decline for the stock since June 2022. The drop followed a sale by majority shareholder IGO Industries Group, which disposed of 4.0% of PORR’s syndicated shares. The transaction lifted the company’s free‑float, including shares held by PORR management, to 56.6% from the prior level of 52.6%. Consequently, the combined holding of the syndicate comprising IGO Industries and Strauss Group – PORR’s two principal shareholders – fell to 43.4% of the equity. PORR confirmed that the syndicate’s structure and its control over the company remain unchanged. CEO Karl‑Heinz Strauss commented that an increased free‑float and a broader investor base are viewed positively by the capital market, as they enhance stock liquidity, raise international visibility and improve the firm’s attractiveness to investors.
