Traffic at Charles de Gaulle and Orly will fall 65-70% rather than the previously forecast 63%, ADP said as it posted January-September revenue of 1.67 billion euros, down 53%.
ADP, which also holds stakes in international airports in countries including Turkey and India, said aviation and retail revenue both fell by more than half in the period.
Traffic has suffered a "new strong decrease" in recent weeks, Chief Financial Officer Philippe Pascal said, "as a consequence of the new wave of epidemic around the world."
ADP is rolling out Covid-19 testing at the Paris airports, but Pascal declined to comment on the target passenger capacity.
