As previously disclosed by Alliant Techsystems Inc. (“ATK”) in Forms 8-K dated May 12, 2011 and August 18, 2011 and in its Form 10-Q for the quarter ended October 2, 2011:

·                  On May 12, 2011, ATK was notified by the U.S. Army that ATK had not been awarded a contract for the continued operation and maintenance of the Radford Army Ammunition Plant (“RFAAP”).

·                  After receiving a debriefing from the U.S. Army, ATK filed a protest of the award with the Government Accountability Office (“GAO”), requesting that the GAO review the RFAAP competition decision.

·                  In August 2011, ATK was informed that ATK’s protest of the award had resulted in the U.S. Army deciding to take corrective action, including amending the solicitation, reopening discussions, and requesting and evaluating revised proposals.

·                  In October 2011, ATK submitted a revised proposal and also filed a pre-award protest with the GAO, as ATK did not believe that the U.S. Army had taken the appropriate corrective actions.

On January 23, 2012, ATK was notified that the GAO did not uphold ATK’s pre-award protest.

ATK awaits the U.S. Army’s decision on the RFAAP competition.
