The EV startup added that discussions regarding the sale of its assets remain ongoing. The company's operating unit, Fisker Group, made the bankruptcy filing on Monday and listed assets of around $500M-$1B and liabilities of $100M-$500M. In February, Fisker ( OTC:FSRN ) had raised doubts about its ability to remain in business, after which its attempt to secure an investment from a big automaker failed. The New York Stock Exchange in March began steps to delist shares of Fisker's common stock due to its "abnormally low" price.
