According to a Business Week report, Motorola has been unable to find a buyer for its mobile phone unit and may have to revamp the division internally. The problem, the report claims, is that analysts are currently valuing it at US$8 billion but, as its market share continues to decline, so does the business’ value. The report adds that new CEO Greg Brown has given strong signals he is intent on overhauling the mobile phone business internally. Earlier this month he announced he is to take operational control of the unit, replacing former head man Stu Reed. “Those familiar with Brown’s plans say he has been weeding out underperforming executives and those he had no hand in hiring,” says the report. “Meanwhile he’s attempting to attract the talent Motorola desperately needs.”

Key to any overhaul would be development of a new product line to follow the success of its RAZR porfolio, the fastest selling handsets in history. Analysts are urging Motorola to spend up to US$2 billion on such development. Meanwhile the report adds that although a sale isn’t imminent, a joint venture or partnership with a company “with a proven track record in consumer marketing” is conceivable.
