Mitsubishi Motors has forecast a sharp slowdown in profit growth this year, warning of an earnings drop in the key US market and a long haul before it breaks even at home, Reuters reported. Mitsubishi, owned 37% by DaimlerChrysler, said it expected group operating profit to rise 8.7% to 90 billion yen ($US770 million) in the year to next March, in line with analysts' forecasts, Reuters said, noting that the restructuring company reported operating profit growth of 106% in the just-completed financial year.
