Warner Bros TV president Peter Roth has claimed that no decision has been made on the future of Fringe.
Roth told TV Line that it is "too soon to tell" if the struggling sci-fi drama will continue beyond its current fourth season.
Fringe has fallen in the ratings in recent weeks, with the past two episodes hitting a series low in the 18-49 demographic.
The series, which stars Anna Torv and Joshua Jackson, also fell below 3m total viewers for the first time ever.
However, Roth claimed that overnight audience figures may not be representative, since many Fringe fans record the show for later viewing.
"This is a show on Friday nights that audiences love to DVR, and as such we shoot up anywhere from 40% to 63%, when you calculate the Live+7," he explained. "Hopefully that will be good enough for us to continue."
