Northrop Grumman Corporation reported that third quarter 2011 earnings from continuing operations increased 16 per cent to $520 million, or $1.86 per diluted share, from $448 million, or $1.51 per diluted share, in the third quarter of 2010. For the nine months ended September 30, 2011, the company repurchased 28.4 million shares of its common stock for $1.6 billion, and $2.4 billion remained under its current share repurchase authorization.

“Superior operating performance in our businesses drove higher operating income, earnings, cash and a strong book-to-bill ratio for the quarter. Based on year-to-date operating results and effective cash deployment, we are again raising our 2011 EPS guidance. The combination of performance and share repurchases continues to produce strong earnings per share growth despite top line pressures,” said Wes Bush, Chairman, Chief Executive Officer and President.
