Japanese tire maker Bridgestone said on Tuesday it would not raise its latest cash bid of $17 per share to counter Icahn’s raised offer of $18.50 per share in cash. Pep Boys shares fell 3 percent in late morning trading on Wednesday, while Icahn Enterprises shares declined 2 percent. Pep Boys’ retail auto parts business will be a perfect fit for Auto Plus, an auto spare parts company that Icahn Enterprises bought in June, Carl Icahn said in a statement.
