Commenting on Orbital's financial results, Mr. David W. Thompson, Chairman and Chief Executive Officer, said, "With exceptionally strong fourth quarter results, Orbital completed an outstanding year in 2006. The company's commercial satellite business generated strong revenue growth and significantly higher operating profit margins as compared to last year.

"Our missile defense programs also continued to post solid results, as did the other products in our launch vehicles segment. In addition, we completed a long-term debt refinancing late in 2006, enhancing our capital structure and significantly reducing future interest costs. We also expect these positive operational and financial trends to continue in 2007, as we add human space exploration projects as a new contributor to revenue growth and profitability for the company."
