PORR AG: PORR launches sale of treasury shares through accelerated bookbuilding

Vienna (pta029/17.06.2025/17:45 UTC+2)

Today, the management board of PORR AG (PORR or the Company) has decided to offer up to 1,703,674 treasury shares (ISIN AT0000609607), corresponding to around 4.33% of the Company's share capital, to institutional investors by means of an accelerated private placement (accelerated bookbuilding process) (the Placement). By resolution of the annual general meeting on 27 May 2021, the shareholders' pro rata purchase right (subscription right) was excluded.

The proceeds from the Placement of the treasury shares will be used to further strengthen the Company's capital structure as well as investments to capture the increased demand from infrastructure programmes in Germany, Poland and the CEE countries.

Assuming all treasury shares are sold, PORR's free float will increase from 42.9% to approximately 47.3%. Following the private placement and subject to customary exceptions, PORR will be subject to a 180-day lock-up.

The accelerated bookbuilding procedure will be initiated immediately following publication of this announcement. The final number of treasury shares to be sold as well as the price per share in the Placement will be determined by the management board of PORR AG and will be published on the Company`s website after completion of the bookbuilding procedure.
