6. Lockheed Martin is a global defense company engaged in aeronautics, information and electronic systems. Net sales were up 6% to $11.4 billion during the third quarter. The aeronautics segment, which contributes around 30% toward revenue, grew 10% year over year during the September quarter. Following the earnings, Robert Stevens, Lockheed chairman and CEO, said, "In addition, we agreed with the government on price for the fourth production lot of F-35 aircraft, and we were notified that Israel signed a Letter of Offer and Acceptance for the procurement of the F-35 as the Israeli Air Force's next-generation fighter aircraft." Joseph Nadol, analyst at JPMorgan, observed, "Earnings per share of $1.55 beat our estimate by 3 cents, including 2 cents from operations. Most of the upside was in electronics, and aeronautics and space EBIT were modestly above expectations as well. " Nadol pegs 2011 top-line growth at around 3.7% with an operating margin of 10.7%. The stock is trading at six to seven times its 2011 earnings.
