Delivery Hero's shares plunged 14% earlier on Friday following news of the recommendation by the Korea Fair Trade Commission's (KFTC) case team. By 1615 GMT, shares were 5.9% down on the day.
Delivery Hero's Chief Executive Niklas Oestberg told an analysts' call on Friday the German company may suggest alternative remedies to sway the regulator.
"We see it as a starting point for negotiations," Oestberg said. "On the negative side, we now see the process will take one to three months longer," he added.
The company said KFTC Commissioners will make their final decision after hearing both Delivery Hero's and the case team's positions.
