Shares of Perot Systems (PER) were among technology's losers Tuesday, falling 15.1% after the information technology services company said that it lost its Harvard Pilgrim Health Care contract.
Perot Systems said Harvard Pilgrim would replace Perot's transaction processing platform with a new system provided by UnitedHealth Group. The new system, which is expected to be phased in during the next three years, is not expected to have a material impact on Perot's financial results during the next 15 months, it said. According to Perot, Harvard Pilgrim currently represents about 5.5% of Perot's sales and gross profit. Finally, Perot said that it is entitled to a break-up fee associated with the cancellation of the contract. The amount of the fee, which should be finalized during the next several months, is expected to be material and realized in 2006. Shares traded down $2.27 to $12.75.
