The FactSet consensus is for sales of $2.8 billion. “The decrease in total net sales and operating revenues is primarily driven by the reduction in retail units sold,” the company said in a regulatory filing. It now expects to sell between 76,000 and 79,000 retail units, down from 105,185 a year ago. The FactSet consensus is for sales of 83,000 retail units.
