Shares in MobilityOne slumped after the electronic payments group said it expects to report a loss far below market expectations for the year to December 31.Accounts currently indicate a loss of about £880,000 on turnover of around £12.5m, the firm said."Demand for the group's products and services has been affected by the weak business sentiment and some projects and expansion plans have been delayed," it said. "In addition to the poor trading conditions the loss was compounded by provisions for impairment and write down of assets."MobileOne said it expects 2009 to remain challenging.
