Chief Executive Officer Marillyn Hewson, who took over on Jan. 1, told reporters the company's results in 2012 were "extraordinary" but that Lockheed remained focused on cutting costs and ensuring performance on key contracts. Lockheed said fourth-quarter sales fell slightly to $12.1 billion from $12.21 billion. The company said it expected sales of $44.5 billion to $46 billion this year, down from $47.18 billion in 2012, but Hewson said there were no additional workforce reductions in the works at this point. Shares of Lockheed were down 1.9 percent at $94.23 in morning trading.
