Moog Inc. (MOG.A) (MOG.B) announced today that it has completed the acquisition of American Pacific Corporation’s (APFC) In-Space Propulsion business for $46 million in cash. The In-Space Propulsion business, with locations in New York, California, Ireland and the United Kingdom, is a developer and manufacturer of liquid propulsion systems and components for satellites and missile defense systems.

The acquisition provides Moog with additional capabilities, specifically in spacecraft controls. “The In-Space Propulsion business complements our existing components and expands our propulsion systems capabilities,” stated Jay Hennig, President of Moog’s Space and Defense Group. “We believe that this will expand our European presence and provide additional scale to serve our customers with a complete satellite control offering.”

The acquisition is expected to add approximately $8 million to Moog’s sales for the remaining two months of the 2012 fiscal year and $50 million to sales for 2013. As a result of first year purchase accounting adjustments, the acquisition is expected to be neutral to previously forecasted fiscal year 2012 and 2013 earnings per share estimates.
