The Merger of Equals - Orbital and ATK Aerospace and Defense Groups, SpaceRef Business
"It is being billed as a merger of equals to create a new company called Orbital ATK. At first glance it appears to be a reaction to the current state of the market with consolidation and future growth needing a larger more competitive entity."
"Orbital Sciences Corporation (ORB) today announced that it has entered into a definitive agreement with Alliant Techsystems Inc. (ATK) , which will combine Orbital and ATK's Aerospace and Defense (A&D) Groups to create a $4.5 billion (combined calendar year 2013 annual revenue), 13,000-person space, defense and aviation systems developer and manufacturer. The new company, to be called Orbital ATK, Inc., will serve U.S. and international customers with leading positions in the markets for space launch vehicles and propulsion systems, tactical missiles and defense electronics, satellites and space systems, armament systems and ammunition, and commercial and military aircraft structures and related components. As part of the transaction, ATK will spin off its Sporting Group, which focuses on commercial sporting equipment, to its shareholders."
