Orbital ATK, Inc. (OA), a global leader in aerospace and defense technologies, today announced both GAAP and adjusted financial results for the third calendar quarter ended October 4, 2015. In addition to GAAP results, the company is presenting adjusted results because it believes these non-GAAP metrics are useful to understand the underlying operating performance of the company by including the pre-merger Orbital and ATK Aerospace and Defense results in comparable periods and excluding significant transaction and merger-related expenses and other non-operational expenses in all periods (for details see reconciliation tables at the end of this release).
Orbital ATK reported adjusted revenues of $1,135 million in the third quarter of 2015 compared to adjusted revenues of $1,112 million in the comparable period of 2014. Adjusted operating income and profit margin were $134.9 million and 11.9%, respectively, in the third quarter of 2015, compared to $120.5 million and 10.8%, respectively, in the same quarter of 2014. Adjusted earnings per share in the quarter were $1.35, compared to $1.15 in the same period of 2014. Adjusted free cash flow was $114.7 million in the quarter ended October 4, 2015.
The company reported GAAP revenues of $1,135 million for the third quarter of 2015 compared to $743 million in the same quarter in 2014.
