Carvana sent the following statement to CNBC late Wednesday: "Carvana is not involved in any cooperative agreement amongst bondholders and we will not be addressing any questions that arise from actions taken by such bondholders.Our message to our customers, shareholders, employees and other stakeholders remains clear: we are singularly focused on executing on the plan to profitability outlined in our Q3 Shareholder Letter and we have substantial liquidity to get us there.Carvana has received a litany of analyst downgrades since the company reported disappointing third-quarter earnings last month and gave a bleak outlook.Carvana has repeatedly borrowed money to cover its losses and growth initiatives, including an all-cash $2.2 billion acquisition earlier this year of Adesa's U.S. physical auction business from KAR Global.Last week, Bank of America downgraded Carvana to neutral, saying that the company badly needs more liquidity as it struggles to turn profitable."
