After a delay pushed the completion of a series of moves by ATK into 2015, the company completed the spinoff of its sporting business and merged the remaining units with Orbital Sciences on 9 February.
Starting on 10 February the new defence- and space-focused company, Orbital ATK, began trading under the symbol OA on the New York Stock Exchange.
ATK spun off its highly profitable sporting group with the name Vista Outdoors. Orbital ATK's combined units reported USD4.5 billion in 2013 revenue, with 12,000 employees in the newly formed company.
Orbital ATK will operate with three units headquartered in Dulles, Virginia.
