Item 4.01. Changes in Registrant’s Certifying Accountant.

As previously disclosed by Orbital ATK, Inc. (the “Company”) in a Current Report on Form 8-K filed on March 2, 2015, the Audit Committee of the Company’s Board of Directors notified PricewaterhouseCoopers LLP (“PwC”) on February 24, 2015 that PwC had been approved as the Company’s independent registered public accounting firm for the fiscal period ending December 31, 2015, subject to completion of PwC’s standard client acceptance procedures and execution of an engagement letter.

On June 30, 2015, the Company and PwC executed an engagement letter formally engaging PwC as the Company’s independent registered public accounting firm.

During the Company’s two most recent fiscal years ended March 31, 2015 and 2014 and the subsequent interim period through June 30, 2015, the Company did not consult with PwC regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and PwC did not provide either a written report or oral advice to the Company that was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue; or (ii) the subject of any disagreement, as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions, or a reportable event within the meaning set forth in Item 304(a)(1)(v) of Regulation S-K.
