Pandora Media stock plunged as much as 26 percent on Friday as things went from bad to worse after its third quarter earnings report.

The company revised its fourth quarter revenue forecast downward, to a range of $365 million to $380 million, Pandora CFO Naveen Chopra revealed on a conference call with investors Thursday evening. That is well below the consensus estimate of $413 million before the report, according to FactSet.
