An activist is pushing Peloton to fire its chief executive officer and consider a sale as its share price has plummeted, according to a report in the Wall Street Journal.

Blackwells Capital, which has a stake of less than 5% in Peloton, believes Peloton could be an attractive acquisition target for larger technology or fitness-oriented companies, people familiar with the matter told the paper.

Blackwells is arguing that Peloton is weaker today than before the pandemic, according to the report. The firm places much of the blame on CEO John Foley, who is also chairman, the report said.

Spokespeople for Peloton and Blackwells didn’t immediately respond to CNBC’s requests for comment. Foley also didn’t return a request for comment.

To be sure, Foley and other insiders have super-voting Class B shares, which gave them control over 80% of Peloton’s voting power as of Sept. 30, according to a proxy filing. That means it would take significant pressure from other shareholders to make any change at the company.

Peloton’s stock is now trading below its September 2019 initial public offering price of $29. It closed Friday at $27.06, giving the company a market cap of $8.8 billion. Roughly a year ago, Peloton’s market value topped out at nearly $50 billion.
