Lockheed, which builds everything from F-35 fighter jets, national security satellites to new coastal warships, said earnings per share had dropped 19 percent to $1.73 in the fourth quarter from $2.14 a year earlier, reflecting a large noncash pension adjustment, higher income tax expenses and a special charge for job cuts in its aeronautics division.

Analysts polled by Thomson Reuters I/B/E/S had expected fourth-quarter earnings of $1.82 a share.

Lockheed said it expected earnings per share to rise to between $8.80 and $9.10 in 2013, noting that its outlook assumed that the U.S. Congress would avert $500 billion in additional Pentagon spending reductions known as "sequestration" that are due to take effect over the next decade, starting in March.
