Public companies

15. ATK

The defense contractor ATK this year restructured to form three groups — an aerospace group, a defense group and a sporting group. The move was meant to streamline the company’s units and create better efficiency. The company, which produces ammunition and rockets, among other equipment, also brought on Scott D. Chaplin formerly of Stanley and BAE Systems, as general counsel.


ATK produces about 17 million rounds of ammunition daily for government, law enforcement, commercial and international customers.
