(Reuters) -Bed Bath & Beyond Inc said on Monday it was planning to raise some $1 billion through an offering of preferred stock and warrants, in a last-ditch effort to stave off bankruptcy.

The move comes just weeks after the retailer said it had defaulted on a loan, raising concerns about its future.

Shares of the retailer, which closed up 92.1% at $5.86 in wild trading session, were down as much as 25% in extended trading.  

Bed Bath said it was planning to raise about $225 million through an offering of Series A convertible preferred stock and raise an additional $800 million by issuing securities that could be used to buy shares of preferred stock in future installments. 

The retailer said in a securities filing it would “likely file for bankruptcy protection” if the transactions are not consummated.

The embattled retailer said it would use the proceeds of the offering to repay outstanding revolving loans under its asset-based lending (ABL) facility.

Separately, the company also appointed Holly Etlin as interim chief financial officer.

In January, the company raised doubts about its ability to continue as a going concern just months after it announced more than $500 million in new financing, as well as job cuts and 150 store closures.

Retailers in distress often look to bankruptcy protection after the holiday season to take advantage of the cash cushion provided by recent sales.

Bed Bath & Beyond (NASDAQ:) said in January it had defaulted on a loan from JPMorgan Chase (NYSE:) Bank N.A. Bloomberg News reported that the company’s efforts to find a buyer had also stalled.

Prospective buyers sometimes wait until a company files for bankruptcy before agreeing to purchase assets, hoping to negotiate more favorable terms.

Sources have told Reuters that Bed Bath & Beyond has lined up liquidators to close additional stores unless a last-minute buyer emerges.
