Automotive-parts supplier Delphi ( DPH) lowered its guidance Thursday. The company said weak demand and production volumes, notably suspended operations at GM's ( GM) Oklahoma City facility, adverse legal rulings and other factors forced a revision to its forecast. The company previously expected second-quarter revenue of $7 billion to $7.3 billion, but its new guidance is $7 billion to $7.1 billion. Delphi reduced its earnings forecast to between $85 million and $95 million, or 15 cents to 17 cents a share, from its prior target of $160 million to $200 million. The revised projection includes the effect of a $25 million after-tax judgment against the company. For the full year, Delphi was planning on revenue of $28 billion, but now it believes the top line will be $27.5 billion to $28 billion. Net income should reach only $375 million to $475 million, or 67 cents to 85 cents a share, compared with the previous outlook of $600 million. Analysts polled by Thomson First Call are looking for second-quarter earnings of 31 cents and full-year profits of 84 cents. Wall Street's revenue forecast is $7.2 billion for the quarter and $27.7 billion for the year. Shares of Delphi were losing 69 cents, or 7%, to $8.90 in Instinet trading after the close, but volume was light.
