JC Penney under CEO Ron Johnson "could fail very, very quickly" if it doesn't take action to replace its leadership, retail veteran Mark Cohen said Friday.
On CNBC's "Fast Money," Cohen called JC Penney under Johnson's stewardship "an unmitigated catastrophe" and made the case for his ouster.
Cohen, a marketing professor at Columbia University, joins a growing chorus of industry experts weighing in on Johnson's stewardship of the retail giant, whose performance over the past year has been dismal.
Earlier this week, former JC Penney CEO Allen Questrom criticized the company's board of directors and chief executive.
"The board has to take action. They can't be delusional like Ron Johnson is," Questrom told CNBC on Wednesday. "This has been going on long enough. You can't say you're going to make your numbers for the year and then drop a billion dollars." (Read More: JCP Board Can't Be 'Delusional' Like Ron Johnson: Allen Questrom)
Asked whether putting the company through the upheaval of finding a new chief executive wouldn't hurt the company, Cohen didn't mince words.
"I guess the question is whether you'd like to see the company go under in the short, medium or longer term," he said. "This is a crisis that needs prompt and aggressive remediation because without it, this company's liquidity is going to disappear, and it could very well disappear as a viable enterprise."
Cohen said that JC Penney had a "window of opportunity" in which to act, after which it would still need "tremendous cooperation" from the financial community and its vendors to reformulate a winning retail strategy.
"But the one they're operating under today has no forward viability in my view," he added.
Cohen, formerly the CEO of Sears Canada, also had a bleak assessment for his old parent company.
"Sears is on a slow, downward spiral, whereas JC Penney has basically nosedived into the ground in a very short period of time," he said.
Both companies, however, would meet the same fate, according to Cohen.
"Sears probably can continue to do business for some period of time. It eventually will fail," he said. "There is no long-term future, in my view, whereas JC Penney could fail very, very quickly if it continues on the trajectory that it's now on."
