Carvana shares soared over 30% in after-hours trading after reporting first-quarter revenue of more than a billion, beating analyst estimates. The company forecast a sequential rise in adjusted core profit and retail unit sales growth, surprising analysts who expected a sales decline. Adjusted earnings before interest, tax, depreciation, and amortization were more than $200 million, exceeding estimates. Carvana's inventory of unsold used vehicles on dealer lots rose 9% from a year ago. High interest rates have pushed some consumers to the used car market for better deals than new vehicles.
