The CEO of Phonak Holding in Switzerland says he won’t be deterred, at least for now, by the German cartel office veto of the company’s acquisition of GN ReSound. Valentin Chapero said Phonak will work to alleviate regulatory authorities’ concerns that eliminating yet another independent hearing-aid manufacturer from the hearing-aid market will give the remaining giants – especially Phonak and German giant Siemens – de-facto monopoly pricing power. If the merger goes through there will be only six major manufacturers controlling the vast majority of global hearing-aid sales.
