The Czech Republic’s largest brewing group, Plzeňský Prazdroj, is facing an unannounced local investigation by the Office for the Protection of Competition (ÚOHS). The antitrust authority is examining potential abuse of a dominant position regarding beer sales within the ‘on-trade’ sector, which encompasses restaurants, pubs, and other gastronomic establishments.

Plzeňský Prazdroj, which is owned by the Japanese group Asahi, confirmed the inspection took place and stated it intends to use “available legal means to defend its rights,” expressing doubts regarding the “legality and proportionality of the investigation.” The ÚOHS noted that the execution of a local investigation does not inherently imply that illegal activity occurred.
