EXPLANATORY NOTE TO AMENDMENT NO. 1

The purpose of this Amendment No. 1 to the Quarterly Report on Form 10-Q (this "Amendment" or "Form 10-Q/A") for the quarter ending April 3, 2016, previously filed on May 9, 2016 (the "Original Filing") with the Securities and Exchange Commission (the "SEC"), is to restate our previously issued condensed consolidated financial statements and related disclosures in our Original Filing.

In this Amendment, we have restated our unaudited condensed consolidated financial statements for the quarter ended April 3, 2016 and restated the unaudited condensed consolidated statement of comprehensive income and the unaudited condensed consolidated statement of cash flow for the quarter ended March 31, 2015. The condensed consolidated balance sheet at December 31, 2015 was derived from the audited financial statements included in our Amended Transition Report on Form 10-K/A for the nine-month transition period ended December 31, 2015 filed on February 24, 2017 ("Form 10-K/A") with the SEC. The Form 10-K/A restated our consolidated financial statements for the nine-month transition period ended December 31, 2015 (“2015 transition period”), fiscal year ended March 31, 2015 (“fiscal 2015”), fiscal year ended March 31, 2014, the quarters in the 2015 transition period and fiscal 2015 and the unaudited selected financial data for the fiscal year ended March 31, 2013. We refer to the misstatement corrections contained in the restated financial statements described herein and the Form 10-K/A collectively as the “Restatement.” For further information regarding the Restatement, see the Form 10-K/A and Part I, Item 1, Financial Statements - Note 3 “Restatement,” to the condensed consolidated financial statements in this Amendment.

Description of the Restatement

As previously disclosed in the Company’s Current Reports on Form 8-K filed on August 10, 2016 and November 3, 2016, the Audit Committee of the Board of Directors (the “Audit Committee”) of the Company, after considering the recommendation of management, concluded that the Company’s previously issued financial statements for the periods mentioned above, as well as the quarters in fiscal 2014, the quarters in fiscal 2013 (except for the first quarter) and the quarter ended April 3, 2016, should no longer be relied upon as a result of misstatements resulting in the Restatement. The Restatement corrects misstatements primarily related to:

(i) the estimation of contract costs at completion on the long-term contract (the “Lake City Contract”) with the U.S. Army to manufacture and supply small caliber ammunition at the Lake City Army Ammunition Plant in Independence, Missouri (the "LCAAP"). The Lake City Contract is within the Small Caliber Systems Division, a business unit within the Company’s Defense Systems Group. The Lake City Contract is a fixed price contract accounted for under the percentage of completion revenue recognition method. The misstatements in the estimation of contract costs at completion caused a forward loss provision to not be timely identified and recorded in prior periods; and

(ii) the Company’s accounting policy, which resulted in the incorrect measurement of forward losses as a result of excluding general and administrative costs from the forward loss when general and administrative costs should be included in the measurement of a forward loss.

In addition to the matters in (i) and (ii) mentioned above, we also corrected for (iii) certain immaterial out of period adjustments previously recorded in the Transition Report on Form 10-K for the nine month period ended December 31, 2015 filed with the SEC on March 15, 2016 that related to misstatements in the application of purchase accounting with respect to acquired long-term contracts accounted for under the percentage of completion revenue recognition method (the "Prior Restatement"); and (iv) various other misstatements which are immaterial both individually and in the aggregate and which were identified during an account review and analysis exercise.

In view of the Restatement, management conducted a comprehensive and intensive review of all relevant material contracts throughout the Company. No material adjustment to the accounting for any of these contracts was required as a result of this review, nor were any circumstances similar to those at the Small Caliber Systems Division discovered.

Background

Before its merger with Orbital Sciences Corporation in 2015, the Company, then known as Alliant Techsystems Inc. or ATK, already had many years of experience with contracts involving operation and production of ammunition at U.S. Army ammunition plants. ATK had operated the LCAAP since 2000 and had operated the U.S. Army’s Radford, Virginia ammunition plant from 1995 to 2012.

In September 2012, ATK was awarded the Lake City Contract for the continued production of ammunition and continued operation and maintenance of the LCAAP. Anticipating strong price competition during the bid process in 2012, ATK submitted

a significantly lower price to the U.S. Army than ATK had experienced under the predecessor contract for LCAAP. Based on its long experience in successfully and profitably managing U.S. Army ammunition contracts, ATK believed it would, among other things, be able to substantially reduce operating costs over the life of the Lake City Contract. While the Company did succeed in achieving significant cost reductions at the LCAAP, these cost reductions were not sufficient to achieve profitability over the life of the Lake City Contract.

The Lake City Contract has an initial term of seven years plus the possibility of an award term extension of an additional three years if by July 17, 2017 the Company does not provide written notice of rejection to the U.S. Army. It is probable that the Company will provide written notice of rejection to the U.S. Army. As a result, the Restatement presents the total estimated forward loss provision for the initial seven-year term.

Certain of the misstatements arising out of the Lake City Contract were initially identified by Orbital ATK senior management in 2016 in connection with our enterprise-wide business optimization program, which was recommended by the Board of Directors to be performed by management. This program includes working capital efficiency initiatives and ongoing efforts to enhance accounting controls and oversight, and is part of our remediation activities in response to material weaknesses identified in connection with the Prior Restatement. Senior management’s identification of these misstatements led to the internal investigation described below. Senior management identified that the prior period estimates of underlying contract costs estimated at completion for the Lake City Contract contained misstatements which, when corrected, resulted in the Lake City Contract’s estimated costs at completion exceeding the contracted revenues for the seven-year term. This necessitated a charge for the entire anticipated forward loss on the Lake City Contract in the period in which the loss became evident. The Company determined that $32 million of the loss should have been evident at contract signing (second quarter of fiscal 2013) and $342 million should have been evident at the time of first production (second quarter of fiscal 2014), and restated those periods and the consequential impact in subsequent periods. Due to the contract loss, we also recorded impairments to goodwill for the Small Caliber Systems Division reporting unit and the value of the long-lived assets within the LCAAP asset group in fiscal 2014. Subsequent to the impairments, costs incurred for the purchase or construction of additional long-lived assets related to this contract were expensed in the periods incurred, as such costs will not be recovered.

Internal Investigation

The Audit Committee of the Board of Directors, in consultation with senior management, determined that the Company should conduct an internal investigation, under its supervision, of the circumstances surrounding the misstatements in the accounting for the Lake City Contract and related matters. The investigation was undertaken by outside counsel, along with independent counsel for the Audit Committee. Counsel received assistance from outside forensic accountants. As disclosed in the Form 10-K/A, the investigation was previously completed.

The Board of Directors and management are fully committed to maintaining a strong internal control environment. The Company has taken and will continue to take significant and comprehensive remedial actions in response to the conduct and other factors that led to the Restatement, including actions to begin to remediate the material weaknesses in internal control over financial reporting identified by management that contributed to the misstatements.

For more information about the internal investigation, the specific material weaknesses in internal control over financial reporting and the Company’s remedial actions, please see Part I, Item 4 Controls and Procedures.

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(Amounts in thousands except share and per share data, unless otherwise indicated)

1. Basis of Presentation and Responsibility for Interim Financial Statements

The unaudited condensed consolidated financial statements of Orbital ATK, Inc. ("the Company" or "Orbital ATK") as set forth in this quarterly report have been prepared in accordance with the requirements of the U.S. Securities and Exchange Commission ("SEC") for interim reporting. As permitted under those rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States can be condensed or omitted. The Company’s accounting policies are described in the notes to the consolidated financial statements in its Amended Transition Report on Form 10-K/A for the nine-month transition period ended December 31, 2015 ("Form 10-K/A") filed on February 24, 2017 with the SEC. Management is responsible for the unaudited condensed consolidated financial statements included in this document. The condensed consolidated financial statements included in this document are unaudited but, in the opinion of management, include all adjustments necessary for a fair statement of the Company’s financial position as of April 3, 2016, and its results of operations and cash flows for the quarters ended April 3, 2016 and March 31, 2015.

On February 9, 2015, the Company completed a tax-free spin-off of and distribution of its former Sporting Group to its stockholders (the "Distribution") as a new public company called Vista Outdoor Inc. ("Vista Outdoor"). Immediately following the Distribution, the Company combined with Orbital Sciences Corporation ("Orbital") through the merger of a Company subsidiary with Orbital (the "Merger"). These transactions are discussed in greater detail in Note 5. Following the Distribution and Merger, the Company changed its name from Alliant Techsystems Inc. to Orbital ATK, Inc.

As a result of the Distribution, Sporting Group is no longer reported within the Company’s results from continuing operations but is reported as a discontinued operation for all prior periods presented. The Company used the acquisition method to account for the Merger; accordingly, the results of Orbital have been included in the Company's consolidated financial statements since the date of the Merger.

Following the Distribution and Merger, the Company reorganized its business groups and realigned its reporting segments. The Company’s remaining businesses, combined with the businesses of Orbital, are now reported in three segments: Flight Systems Group, Defense Systems Group and Space Systems Group, as discussed in Note 20. The business comprising Sporting Group is presented as a discontinued operation - see Note 5.

Sales, expenses, cash flows, assets and liabilities can and do vary during the year. Therefore, the results and trends in these interim financial statements may not be the same as those for the full year. Certain reclassifications have been made to prior year amounts to conform to current year presentation.

This Amended Report on Form 10-Q ("Form 10-Q/A") should be read in conjunction with the Company’s consolidated financial statements and notes included in its Form 10-K/A for the nine-month transition period ended December 31, 2015.

Fiscal Year Change. The Company's interim quarterly periods are based on 13-week periods and end on Sundays. The quarter ended March 31, 2015 did not end on a Sunday because it was the last quarter of the Company's fiscal year ended March 31, 2015. On March 10, 2015, the Company's Board of Directors approved a change in the Company's fiscal year end from March 31 to a calendar year ending on December 31 of each year. The Company filed a Transition Report on Form 10-K for the nine-month transition period ended December 31, 2015 on March 15, 2016 which was subsequently amended on February 24, 2017.

Restatement of Previously Issued Consolidated Financial Statements. In this Form 10-Q/A, the Company restated its unaudited condensed consolidated financial statements for the quarter ended April 3, 2016 and restated the unaudited condensed consolidated statement of comprehensive income and the unaudited condensed consolidated statement of cash flows for the quarter ended March 31, 2015. The condensed consolidated balance sheet at December 31, 2015 was derived from the audited financial statements included in the Form 10-K/A but does not include all of the information and footnotes required by U.S. Generally Accepted Accounting Principles ("U.S. GAAP") for complete financial statements.

Such restatements were made to correct errors primarily related to (i) errors identified in estimating contract costs at completion on a certain long-term contract accounted for under the percentage of completion revenue recognition method causing a forward loss provision to not be identified timely and recorded; and (ii) correcting the Company’s accounting policy for measurement of forward loss provisions; and (iii) certain other immaterial misstatements.

See Note 3-"Restatement," for additional information regarding the errors identified in this Form 10-Q/A and the restatement adjustments made to the Condensed Consolidated Financial Statements.

2. New Accounting Pronouncements

Accounting Standards Updates Adopted

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2016-09, Compensation--Stock Compensation (Topic 718) Improvements to Employee Share-Based Payment Accounting, which requires the recognition of the income tax effects of awards in the income statement when the awards vest or are settled, thus eliminating additional paid in capital pools. The guidance also allows for the employer to repurchase a greater number of an employee’s shares for tax withholding purposes without triggering liability accounting. In addition, the guidance allows for a policy election to account for forfeitures as they occur rather than on an estimated basis. The guidance is effective for annual reporting periods beginning after December 15, 2016 with early adoption permitted. The Company elected to early adopt this ASU effective for the quarter ended April 3, 2016. The adoption of this new standard did not have a material impact on the Company's condensed consolidated financial statements.

In May 2015, the FASB issued ASU 2015-07, Disclosures for Investments in Certain Entities That Calculate Net Asset Value per Share (or Its Equivalent), which removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. Such investments should be disclosed separate from the fair value hierarchy. This ASU became effective retrospectively for the Company beginning in the quarter ended April 3, 2016. The adoption of this new standard did not have an impact on the Company's condensed consolidated financial statements but impacted certain disclosures reflected in the notes to the accompanying condensed consolidated financial statements.

In April 2015, the FASB issued ASU No. 2015-03, Simplifying the Presentation of Debt Issuance Costs and in August 2015, the FASB issued ASU No. 2015-15, “Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.” These ASUs more closely align the treatment of debt issuance costs with debt discounts and premiums and requires debt issuance costs to be presented as a direct deduction from the carrying amount of the related debt. The amendments in these ASUs became effective for the Company in the current quarter ended April 3, 2016. The adoption of these new standards impacted the presentation of the current and prior period debt issuance costs included in Note 12.

In February 2015, the FASB issued ASU 2015-02, Amendments to the Consolidation Analysis, which simplifies the consolidation evaluation process by placing more emphasis on risk of loss when determining a controlling financial interest. This new standard is effective for interim and annual periods beginning after December 15, 2015. The adoption of this new standard did not have a material impact on the Company's condensed consolidated financial statements.

Accounting Standards Updates Issued But Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which requires recognition of lease assets and lease liabilities for those leases classified as operating leases under previous generally accepted accounting principles in the United States ("U.S. GAAP"). The new standard is effective for annual reporting periods beginning after December 15, 2018 with early adoption permitted. The Company currently is evaluating the potential changes from this ASU to its future financial reporting and disclosures.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), which will replace numerous requirements in U.S. GAAP, including industry-specific requirements, and provide companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. Under the new standard, the Company expects to continue using the cost-to-cost percentage of completion method to recognize revenue for most of its long-term contracts. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application. The Company has not yet selected a transition method. The Company currently is evaluating the potential changes from this ASU to its future financial reporting and disclosures. In July 2015, the FASB approved the deferral of the new standard's effective date by one year. The new standard now will be effective for annual reporting periods beginning after December 15, 2017. The FASB will permit companies to adopt the new standard early, but not before the original effective date of annual reporting periods beginning after December 15, 2016.

Other new pronouncements issued but not effective for the Company until after April 3, 2016 are not expected to have a material impact on the Company's continuing financial position, results of operations or liquidity.

3. Restatement

In February 2017, the Company filed the Form 10-K/A to restate its consolidated financial statements for the nine-month transition period ended December 31, 2015 ("2015 transition period"), fiscal year ended March 31, 2015 ("fiscal 2015"), fiscal year ended March 31, 2014 ("fiscal 2014"), the quarters in the 2015 transition period and fiscal 2015 (the "Restatement") to correct errors primarily related to (i) the estimation of contract costs at completion on the long-term contract (the “Lake City Contract”) with the U.S. Army to manufacture and supply small caliber ammunition at the Lake City Army Ammunition Plant ("LCAAP") causing a forward loss provision to not be identified timely and recorded in prior periods; and (ii) correcting the Company’s accounting policy for measurement of forward loss provisions. In this Form 10-Q/A, the Company restated its unaudited condensed consolidated financial statements for the quarter ended April 3, 2016 for the consequential impact of these errors in subsequent periods. Additionally, the unaudited condensed consolidated statement of comprehensive income and the unaudited condensed consolidated statement of cash flows for the quarter ended March 31, 2015 are being restated in this Form 10-Q/A for these matters.

The Lake City Contract is within the Small Caliber Systems Division, a business unit within the Company’s Defense Systems Group, and is a fixed price contract accounted for under the percentage of completion revenue recognition method. The Lake City Contract was entered into in September 2012. It has an initial term of seven years plus the possibility of an award term extension of an additional three years if by July 17, 2017 the Company does not provide written notice of rejection to the U.S. Army. It is probable that the Company will provide written notice of rejection to the U.S. Army. As a result, the Restatement presents the total estimated forward loss provision for the initial seven-year term.

Management identified that the underlying contract costs estimated at completion for the Lake City Contract in prior periods contained misstatements which, when corrected, resulted in the Lake City Contract’s estimated costs at completion exceeding the contracted revenues. This necessitated a forward loss charge for the seven-year term of the Lake City Contract to be recorded for the entire anticipated forward loss on the contract in the period in which the loss became evident. The Company determined that $31,500 of the loss was evident at contract signing (second quarter of fiscal 2013) and $342,000 became evident at the time of initial production (second quarter of fiscal 2014) and restated those periods and the consequential impact in subsequent periods.

Due to the contract loss identified at the Lake City facility, the Company recognized an impairment charge for the long lived assets capitalized for the Lake City Ammunition Plant asset group in fiscal 2014. Subsequent to the impairments, costs incurred for the purchase or construction of additional long-lived assets related to this contract were expensed in the periods incurred, as such costs will not be recovered, and the depreciation expense recorded in subsequent periods was revised. The impairment charge recognized on long lived assets was $857 and $8,962 in the quarters ended April 3, 2016 and March 31, 2015, respectively.

The Company corrected its accounting policy from measurement of a forward loss provision based on gross profit to measurement based on gross profit along with general and administrative costs and adjusted the previously recorded forward loss provisions. The Company's prior accounting policy for measurement of a forward loss excluded general and administrative

costs from the forward loss determination resulting in an incorrect measurement of a forward loss as these costs should be included in the measurement. The aggregate impact of this correction to the contract loss reserve liability, excluding the adjustment for the Lake City Contract, was an increase of $3,291 at April 3, 2016. As part of the correction in accounting policy, the Company also reclassified certain forward loss provisions recorded in net receivables to the contract loss reserve liability.

In addition to the matters in (i) and (ii) described above, the Company also corrected for (iii) certain immaterial out of period adjustments previously recorded in the Transition Report on Form 10-K for the nine month period ending December 31, 2015 filed with the SEC on March 15, 2016 that related to misstatements in the application of purchase accounting with respect to acquired long-term contracts accounted for under the percentage of completion revenue recognition method and (iv) various other misstatements which are immaterial both individually and in the aggregate and which were identified during an account review and analysis exercise.

A summary of the impact of these matters on income (loss) from continuing operations, before income taxes and noncontrolling interest is presented below:

4. Fair Value of Financial Instruments

The current authoritative guidance on fair value clarifies the definition of fair value, prescribes a framework for measuring fair value, establishes a fair value hierarchy based on the inputs used to measure fair value, and expands disclosures about the use of fair value measurements. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The valuation techniques required by the current authoritative literature are based upon observable and unobservable inputs. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect internal market assumptions. These two types of inputs create the following fair value hierarchy:

Level 1—Quoted prices for identical instruments in active markets.

Table of Contents

NOTES TO THE CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

(Amounts in thousands except share and per share data, unless otherwise indicated)

Level 2—Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.

Level 3—Significant inputs to the valuation model are unobservable.

The following section describes the valuation methodologies used by the Company to measure its financial instruments at fair value.

Derivative financial instruments and hedging activities—In order to manage its exposure to commodity pricing, foreign currency risk and interest rate risk on debt, the Company periodically utilizes commodity, foreign currency and interest rate derivatives, which are considered Level 2 instruments. As discussed further in Note 8, the Company has outstanding commodity forward contracts that were entered into to hedge forecasted purchases of copper and zinc, as well as outstanding foreign currency forward contracts that were entered into to hedge forecasted transactions denominated in a foreign currency. Commodity derivatives are valued based on prices of futures exchanges and recently reported transactions in the marketplace. During the fiscal year ended March 31, 2014 ("fiscal 2014"), the Company entered into five interest rate swaps. These swaps are valued based on future LIBOR rates and the established fixed rate is based primarily on quotes from banks. Foreign currency derivatives are valued based on observable market transactions of spot currency rates and forward currency prices.

The carrying amounts of the Company’s financial instruments, other than derivatives, which include net receivables, inventory, accounts payable, accrued liabilities and other current assets and liabilities, are reasonable estimates of their related fair values. The fair value of the variable-rate long-term debt is calculated based on current market rates for debt of the same risk and maturities. The fair value of the fixed-rate debt is based on market quotes for each issuance. The Company considers these to be Level 2 instruments.

The Company’s non-financial instruments measured at fair value on a non-recurring basis include goodwill, indefinite-lived intangible assets and long-lived tangible assets. The valuation methods used to determine fair value require a significant degree of management judgment to determine the key assumptions. As such, the Company generally classifies non-financial instruments as either Level 2 or Level 3 fair value measurements.

The following table sets forth, by level within the fair value hierarchy, the Company's financial assets and liabilities that are measured at fair value on a recurring basis:

Investments in marketable securities—The Company's investments in marketable securities represent investments held in a common collective trust ("CCT") that primarily invests in fixed income securities which are used to pay benefits under a nonqualified supplemental executive retirement plan for certain executives and highly compensated employees. Investments in a collective investment vehicle are valued by multiplying the investee company's net asset value per share with the number of units or shares owned at the valuation date as determined by the investee company. Net asset value per share is determined by the investee company's custodian or fund administrator by deducting from the value of the assets of the investee company all of its liabilities and dividing the resulting number by the outstanding number of shares or units. Investments held by the CCT, including collateral invested for securities on loan, are valued on the basis of valuations furnished by a pricing service approved by the CCT's investment manager, which determines valuations using methods based on market transactions for comparable securities and various relationships between securities which are generally recognized by institutional traders, or at fair value as determined in good faith by the CCT's investment manager. The fair value of these securities, not subject to leveling, is included within other noncurrent assets on the consolidated balance sheet. The fair value of these securities is measured on a recurring basis. The fair value of these securities was $10,751 and $12,065 as of April 3, 2016 and December 31, 2015, respectively.

5. Mergers, Acquisitions and Divestitures

On February 9, 2015, the Company completed the spin-off and Distribution of its former Sporting Group to its stockholders and merged with Orbital pursuant to a transaction agreement, dated April 28, 2014 (the "Transaction Agreement"). The Company completed the Merger with Orbital in order to create a global aerospace and defense company with greater technical and industrial capabilities and increased financial resources. Both the Distribution and Merger were structured to be tax-free to U.S. stockholders for U.S. federal income tax purposes. Under the Transaction Agreement, a subsidiary of the Company merged with and into Orbital, with Orbital continuing as a wholly-owned subsidiary of the Company.

Pursuant to the Distribution, Company stockholders received two shares of Vista Outdoor for each share of Company common stock held. The Company distributed a total of approximately 63.9 million shares of Vista Outdoor common stock to its stockholders of record as of the close of business on February 2, 2015 the record date for the Distribution. As a result of the Distribution, Sporting Group is no longer reported within the Company’s results from continuing operations but is reported as a discontinued operation for all prior periods presented in accordance with ASC Topic 205, "Presentation of Financial Statements." Sales reported as discontinued operations were $186,000 in the quarter ended March 31, 2015.

In connection with the Merger, each outstanding share of Orbital common stock was converted into the right to receive 0.449 shares of Company common stock. The Company issued approximately 27.4 million shares of common stock to Orbital stockholders. Immediately following the Merger, Orbital stockholders owned 46.2% of the common stock of the Company and existing stockholders owned 53.8%. Based on the closing price of the Company's common stock following the Distribution on February 9, 2015 as reported on the New York Stock Exchange, the aggregate value of the consideration paid or payable to former holders of Orbital common stock was approximately $1.8 billion. The Company used the acquisition method to account for the Merger; accordingly, the results of Orbital have been included in the Company's consolidated financial statements since the date of the Merger. Orbital's sales and pre-tax income included in the Company's financial statements for the post-Merger period of February 9, 2015 through March 31, 2015 were approximately $191,000 and $16,000, respectively.

Valuation of Net Assets Acquired

The following amounts represent the final determination (as of the Merger date) of the fair value of identifiable assets acquired and liabilities assumed in the Merger, including adjustments made to date during the one year measurement period from the date of the Merger:

⁽²⁾	The fair value of replacement equity-based awards attributable to pre-Merger service was recorded as part of the consideration transferred in the Merger.

The consideration paid for Orbital's assets and liabilities was determined using the fair market value of the Company stock issued on the closing date of the Merger along with restricted stock awards granted to certain employees of Orbital.

Goodwill recognized from the Merger primarily relates to the expanded market opportunities, expected synergies and benefits of increased scale and scope of combined human, physical and financial resources attributable to merging the operations of the two companies. As stated above, the Merger was a tax-free transaction and as such, goodwill is not amortized for tax purposes.

In determining the fair values of identifiable assets acquired and liabilities assumed, a review was conducted for any significant contingent assets or liabilities existing as of the Merger date. There were no significant contingencies identified related to any legal or government action.

The accompanying condensed consolidated income statement for the quarter ended April 3, 2016 included a measurement period adjustment pertaining to the fair value of intangibles that was immaterial. All elements in the determination of the fair value of identifiable assets acquired and liabilities assumed in the Merger are final as of April 3, 2016.

Supplemental Pro Forma Data

The following unaudited supplemental pro forma data for the quarter ended March 31, 2015 presents consolidated information as if the Merger had been completed on April 1, 2013. The pro forma results were calculated by combining the results from continuing operations of the Company with the stand-alone results of Orbital for the pre-Merger period, which were adjusted to eliminate historical sales between the companies and to account for certain costs which would have been incurred during this pre-Merger period:



	Quarter Ended March 31, 2015
	As Restated
Sales	$	1,088,291
Loss from continuing operations	(29,627		)
Basic earnings per common share from continuing operations	$	(0.49	)
Diluted earnings per common share from continuing operations	(0.49		)

The unaudited supplemental pro forma data above includes the following significant adjustments made to account for certain costs which would have been incurred if the Merger had been completed on April 1, 2013, as adjusted for the applicable income tax impact:



	Quarter Ended March 31, 2015
Amortization of acquired Orbital intangible assets ⁽¹⁾	$	3,877
Interest expense adjustment ⁽²⁾	(6,069		)
Transaction fees for advisory, legal and accounting services ⁽³⁾	(19,134		)

_________________________________________

⁽¹⁾ Added the amortization of acquired Orbital intangible assets recognized at fair value in purchase accounting and eliminated historical Orbital intangible asset amortization expense.

⁽²⁾ Reduced interest expense for the net reduction in debt of the Company and Orbital.

⁽³⁾ Excluded transaction fees for advisory, legal and accounting services incurred in the quarter ended March 31, 2015.

The unaudited supplemental pro forma data above does not reflect the potential realization of cost savings related to the integration of the two companies. Further, the pro forma data should not be considered indicative of the results that would have occurred if the Merger had been completed on April 1, 2013, nor are they indicative of future results.

Ongoing Business with Vista Outdoor

In conjunction with the Distribution, the Company entered into two supply agreements and one Transition Services Agreement ("TSA") with Vista Outdoor. The supply agreements call for Vista Outdoor to purchase certain minimum quantities of ammunition and gun powder from the Company through March 2017 or 2018, as applicable. The supply agreements which are priced at arms-length expire in 2017 (powder) and 2018 (ammunition) and may be extended in one-to-three year increments. Under the terms of the TSA, the Company provided various administrative services to Vista Outdoor for up to 12 months following the Distribution and will provide tax assistance services for 18 months following the Distribution, extendable to 30 months. Fees for services under the TSA are charged to Vista Outdoor.

Sales to Vista Outdoor under the supply agreements were $64,668 (as restated) for the quarter ended April 3, 2016 and $18,928 for the period from the date of the Distribution to March 31, 2015, respectively. Prior to the Merger, sales to Sporting Group, previously reported as intercompany sales and eliminated in consolidation were $13,595 for the quarter ended March 31, 2015.

Diluted weighted-average number of shares outstanding	58,881	46,928
Anti-dilutive stock options excluded from the calculation of diluted shares	147	73

8. Derivative Financial Instruments

The Company is exposed to market risks arising from adverse changes in commodity prices affecting the cost of raw materials and energy, interest rates and foreign exchange risks. In the normal course of business, these risks are managed through a variety of strategies, including the use of derivative instruments. Commodity forward contracts are periodically used to hedge forecasted purchases of certain commodities, foreign currency exchange contracts are used to hedge forecasted transactions denominated in a foreign currency, and the Company periodically uses interest rate swaps to hedge forecasted interest payments and the risk associated with variable interest rates on long-term debt.

The Company entered into forward contracts for copper and zinc during the quarter ended April 3, 2016. The contracts establish a fixed price for the underlying commodity and are designated and qualify as effective cash flow hedges of purchases of the commodity. Ineffectiveness is calculated as the amount by which the change in the fair value of the derivatives exceeds the change in the fair value of the anticipated commodity purchases.

The Company entered into interest rate swaps in fiscal 2014 in order to manage interest costs and the risk associated with variable rates, whereby the Company pays a fixed rate on a total notional amount of $400,000 and receives one-month LIBOR. The fair value of interest rate swap agreements approximates the amount at which they could be settled, based on future LIBOR, and the established fixed rate is based primarily on quotes from banks. The Company performs assessments of the effectiveness of hedge instruments on a quarterly basis and determined the hedges to be highly effective. The counterparties to the interest rate swap agreements expose the Company to credit risk in the event of nonperformance. However, at April 3, 2016, five of the outstanding swap agreements were in a net liability position which would require the Company to make the net settlement payments to the counterparties. The Company does not anticipate nonperformance by the Company's counterparties. The Company does not hold or issue derivative financial instruments for trading purposes.

The Company entered into foreign currency forward contracts during the quarter ended April 3, 2016 to hedge forecasted cash payments to a customer. This transaction was designated and qualified as effective cash flow hedge. Ineffectiveness with respect to forecasted inventory purchases or customer cash receipts was calculated based on changes in the forward rate until the anticipated purchase or cash receipt occurs; ineffectiveness of the hedge of the accounts payable was evaluated based on the change in fair value of its anticipated settlement.

The fair value of the commodity and foreign currency forward contracts is recorded within other assets or liabilities, as appropriate, and the effective portion is reflected in accumulated other comprehensive income (loss) in the financial statements. The gains or losses on the commodity forward contracts are recorded in inventory as the commodities are purchased and in cost of sales when the related inventory is sold. The gains or losses on the foreign currency forward contracts are recorded in earnings when the related inventory is sold or customer cash receipts are received.

Senior Credit Facility

In September 2015, the Company refinanced its Former Senior Credit Facility (as defined below) with a new senior credit facility (the "Senior Credit Facility"), which is comprised of a term loan of $800,000 (the "Term Loan A") and a revolving credit facility of $1,000,000 (the "Revolving Credit Facility"), both of which mature in 2020. The Term Loan A is subject to quarterly principal payments of $10,000, with the remaining balance due on September 29, 2020. Substantially all tangible and intangible assets of the Company and certain domestic subsidiaries, excluding real property, are pledged as collateral under the Senior Credit Facility. Borrowings under the Senior Credit Facility bear interest at a per annum rate equal to either the sum of a base rate plus a margin or the sum of a LIBOR rate plus a margin. Each margin is based on the Company's total leverage ratio. Based on the Company's current total leverage ratio, the current base rate margin is 0.5% and the current LIBOR margin is 1.5%. The weighted-average interest rate for the Term Loan A, after taking into account the interest rate swaps discussed below, was 2.07% at April 3, 2016. The Company pays a quarterly commitment fee on the unused portion of the Revolving Credit Facility based on its total leverage ratio. Based on the Company's current total leverage ratio, this fee currently is 0.25%. As of April 3, 2016, the Company had borrowings of $125,000 under the Revolving Credit Facility and had outstanding letters of credit of $130,316, which reduced amounts available on the Revolving Credit Facility to $744,684. There are unamortized debt issuance costs associated with the Former Senior Credit Facility of $3,361 that will be amortized to interest expense along with $3,306 of debt issuance costs incurred related to the Senior Credit Facility over five years, the term of the Senior Credit Facility.

5.50% Senior Notes

In September 2015, the Company issued $400,000 aggregate principal amount of 5.50% Senior Notes (the "5.50% Notes") that mature on October 1, 2023. These notes are general unsecured obligations. Interest on these notes is payable on April 1 and October 1 of each year. The Company has the right to redeem some or all of these notes from time to time on or

Prior to October 1, 2018, the Company may redeem some or all of these notes at a price equal to 100% of their principal amount plus accrued and unpaid interest to the date of redemption and a specified make-whole premium. In addition, prior to October 1, 2018, the Company may redeem up to 35% of the aggregate principal amount of these notes with the net cash proceeds of certain equity offerings, at a price equal to 105.5% of their principal amount plus accrued and unpaid interest to the date of redemption. Debt issuance costs of $6,136 (as restated) related to these notes are being amortized to interest expense over eight years, the term of the notes.

5.25% Senior Notes

In fiscal 2014, the Company issued $300,000 aggregate principal amount of 5.25% Senior Notes (the "5.25% Notes") that mature on October 1, 2021. These notes are general unsecured obligations. Interest on these notes is payable on April 1 and October 1 of each year. The Company has the right to redeem some or all of these notes from time to time on or after October 1, 2016, at specified redemption prices. Prior to October 1, 2016, the Company may redeem some or all of these notes at a price equal to 100% of their principal amount plus accrued and unpaid interest to the date of redemption and a specified make-whole premium. In addition, prior to October 1, 2016, the Company may redeem up to 35% of the aggregate principal amount of these notes with the net cash proceeds of certain equity offerings, at a price equal to 105.25% of their principal amount plus accrued and unpaid interest to the date of redemption. Debt issuance costs of approximately $2,625 related to these notes are being amortized to interest expense over eight years, the term of the notes.

Former Senior Credit Facility

In September 2015, the Company refinanced and paid off its former senior credit facility (the "Former Senior Credit Facility") which was comprised of a term loan of $1,160,000 (the "Former Term A Loan"), a term loan of $250,000 (the "Former Term B Loan") and a $700,000 revolving credit facility (the "Former Revolving Credit Facility"), all of which were to mature from 2018 to 2020. The Former Term A Loan and the Former Term B loan were subject to quarterly principal payments of $14,500 and $499, respectively. Substantially all domestic tangible and intangible assets of the Company and its subsidiaries were pledged as collateral under the Former Senior Credit Facility. Borrowings under the Former Senior Credit Facility were charged interest at a rate equal to either the sum of a base rate plus a margin or the sum of a Eurodollar rate plus a margin. Each margin was based on the Company's senior secured credit ratings. The Company paid an annual commitment fee on the unused portion of the Former Revolving Credit Facility based on its senior secured credit ratings.

Interest Rate Swaps

At April 3, 2016, the Company had interest rate swap agreements in order to manage interest costs and the risk associated with variable interest rates - see Note 8.

Rank and Guarantees

The 5.50% Notes and the 5.25% Notes are the Company’s general unsecured and unsubordinated obligations and rank equally in right of payment with all of the Company’s existing and future unsecured and unsubordinated indebtedness, rank senior in right of payment to all of the Company’s existing and future subordinated indebtedness and are effectively subordinated to all existing and future senior secured indebtedness, including the Senior Credit Facility, to the extent of the collateral. The 5.50% Notes and the 5.25% Notes are guaranteed on an unsecured basis, jointly and severally and fully and unconditionally, by substantially all of the Company's domestic subsidiaries. The Senior Credit Facility obligations are guaranteed on a secured basis, jointly and severally and fully and unconditionally, by substantially all of the Company's domestic subsidiaries. All of these guarantor subsidiaries are 100% owned by the Company. The Company, exclusive of these guarantor subsidiaries, has no independent operations or material assets. The guarantee by any Subsidiary Guarantor of the Company's obligations in respect of the 5.50% Notes and the 5.25% Notes will be released in each of the following circumstances:


•	if, as a result of the sale of its capital stock, such Subsidiary Guarantor ceases to be a Restricted Subsidiary;


•	if such Subsidiary Guarantor is designated as an "Unrestricted Subsidiary" with respect to the 5.25% Notes and the 5.50% Notes;


•	upon defeasance or satisfaction and discharge of the 5.25% Notes and the 5.50% Notes, as applicable; and


•	if such Subsidiary Guarantor has been released from its guarantees of indebtedness under the credit agreement governing the Senior Credit Facility (the "Credit Agreement") and all capital markets debt securities.

Scheduled Minimum Loan Payments

The scheduled minimum loan payments on outstanding long-term debt are as follows:



Remainder of 2016	$	30,000
Calendar 2017	40,000
Calendar 2018	40,000
Calendar 2019	40,000
Calendar 2020	755,000
Thereafter	700,000
Total	$	1,605,000

Covenants and Default Provisions

The Company's Senior Credit Facility and the indentures governing the 5.50% Notes and the 5.25% Notes impose restrictions on the Company, including limitations on its ability to incur additional debt, enter into capital leases, grant liens, pay dividends and make certain other payments, sell assets, or merge or consolidate with or into another entity. In addition, the Senior Credit Facility limits the Company's ability to enter into sale-and-leaseback transactions. The 5.50% Notes and 5.25% Notes limit the aggregate sum of dividends, share repurchases, and other designated restricted payments to an amount based on the Company’s net income, stock issuance proceeds, and certain other items since April 1, 2001, less restricted payments made since that date. The Senior Credit Facility allows the Company to make unlimited "restricted payments" (as defined in the Credit Agreement), which, among other items, would allow payments for future stock repurchases, as long as the Company maintains a certain amount of liquidity and maintains certain senior secured debt limits, with a limit, when those senior secured debt limits are not met, of $250,000 plus proceeds of any equity issuances plus 50% of net income since October 7, 2010. The Senior Credit Facility also requires the Company to meet and maintain specified financial ratios, including a minimum interest coverage ratio and a maximum consolidated total leverage ratio. The Company's debt agreements contain cross-default provisions so that noncompliance with the covenants within one debt agreement could cause a default under other debt agreements as well. The Company's ability to comply with these covenants and to meet and maintain the financial ratios may be affected by events beyond its control. Borrowings under the Senior Credit Facility are subject to compliance with these covenants. As of April 3, 2016, the Company was in compliance with the financial covenants.

Effective January 1, 2016, the Company changed the approach used to measure service and interest costs for pension and other postretirement benefits. Prior to January 1, 2016, the Company measured service and interest costs utilizing a single weighted-average discount rate derived from the yield curve used to measure the plan obligations. For 2016, the Company has elected to measure service and interest costs by applying the specific spot rates along that yield curve to the plans’ liability cash flows. The Company believes the new approach provides a more precise measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding spot rates on the yield curve. This change does not affect the measurement of our plan obligations. The Company has accounted for this change as a change in accounting estimate and, accordingly, has accounted for it on a prospective basis. This change resulted in approximately $6,000 lower pension expense compared to the method used prior to January 1, 2016.

Employer Contributions. During the three months ended April 3, 2016, the Company contributed $3,334 directly to retirees under its nonqualified supplemental executive retirement plan. The Company also contributed $1,059 to its other postretirement benefit plans.

During the remainder of 2016, the Company anticipates making pension contributions of approximately $37,600 in order to meet the minimum required contributions for 2016. The Company anticipates making additional contributions of approximately $2,048 directly to retirees under the nonqualified plan and $6,505 to its other postretirement benefit plans during the remainder of 2016.

14. Income Taxes

The Company’s income taxes include federal, foreign and state income taxes. Income taxes for interim periods are based on estimated effective annual income tax rates.

The effective income tax rate for the tax expense in the quarter ended April 3, 2016 was 25.1% (as restated) compared to an effective income tax rate of 9.6% (as restated) for the tax benefit in the quarter ended March 31, 2015, reflecting the impact of domestic manufacturing deductions and research and development tax credits in the quarter ended April 3, 2016 and the impact of certain non-deductible costs in the quarter ended March 31, 2015.

The Company or one of its subsidiaries files income tax returns in the U.S. federal, various U.S. state and foreign jurisdictions. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or foreign income tax examinations by tax authorities for years prior to 2010. The IRS has completed the audits of the Company through fiscal 2012 and is currently auditing the Company's income tax returns for fiscal years 2013 and 2014. The Company believes appropriate provisions for all outstanding issues have been made for all remaining open years in all jurisdictions.

Although the timing and outcome of audit settlements are uncertain, it is reasonably possible that a $3,725 reduction of the uncertain tax benefits will occur in the next 12 months. The settlement of these unrecognized tax benefits could result in an increase in net income from $0 to $2,850.

15. Stockholders' Equity

The Company has authorized 5,000,000 shares of preferred stock, par value $1.00, none of which has been issued.

Total pretax stock-based compensation expense of $4,640 and $11,734 was recognized during the quarters ended April 3, 2016 and March 31, 2015, respectively.

(Amounts in thousands except share and per share data, unless otherwise indicated)

The total income tax benefit recognized in the income statement for share-based compensation was $1,804 and $4,538 during the quarters ended April 3, 2016 and March 31, 2015, respectively.

The Company sponsors six stock-based incentive plans: the Orbital ATK, Inc. 2015 Stock Incentive Plan (the "2015 Stock Incentive Plan"); three legacy ATK plans (the Alliant Techsystems Inc. 2005 Stock Incentive Plan, the Non-Employee Director Restricted Stock Plan and the 1990 Equity Incentive Plan); and two legacy Orbital plans, under which the Company assumed the obligation to issue Company common stock pursuant to the terms of the Transaction Agreement relating to the Merger (the Orbital Sciences Corporation 2005 Amended and Restated Stock Incentive Plan and the Orbital Sciences Corporation 1997 Stock Option and Incentive Plan). At April 3, 2016, the Company had authorized up to 3,750,000 common shares under the 2015 Stock Incentive Plan, of which 2,853,398 common shares were available to be granted. No new grants will be made out of the other five plans.

There are five types of awards outstanding under the Company's stock incentive plans: performance awards, total stockholder return performance awards ("TSR awards"), restricted stock units, restricted stock and stock options. The Company issues treasury shares upon (i) the payment of performance awards, TSR awards and restricted stock units, (ii) the grant of restricted stock, and (iii) the exercise of stock options.

Pursuant to the terms of the Transaction Agreement and under the terms of the ATK 2005 Stock Incentive Plan, all of the performance awards and TSR awards outstanding as of February 9, 2015 were converted into time-vesting restricted stock units in connection with the Distribution, with vesting periods corresponding to the respective performance periods. As of December 31, 2015, there were 55,677 shares reserved for the vesting of restricted stock units for the fiscal 2015-2017 performance period on March 31, 2017. During the quarter ended April 3, 2016, 40,707 shares reserved for the vesting of restricted stock units for the fiscal 2014-2016 performance period vested.

As of April 3, 2016, there were 55,677 shares reserved for the vesting of restricted stock units for the fiscal 2015-2017 performance period on March 31, 2017.

As of April 3, 2016, there were up to 82,042 shares reserved for performance awards for the fiscal 2015-2017 performance period for executive officers and key employees. Performance shares are valued at the fair value of the Company stock as of the grant date and expense is recognized based on the number of shares expected to vest under the terms of the award under which they are granted. Of these shares:


•	up to 50% will become payable only upon achievement of a financial performance goal relating to absolute earnings per share growth for the performance period beginning April 1, 2015 and ending December 31, 2017; and


•	up to 50% will become payable only upon achievement of a performance goal relating to absolute sales growth for the performance period beginning April 1, 2015 and ending December 31, 2017.

As of April 3, 2016, there were up to 73,447 shares reserved for performance awards for the fiscal 2016-2018 performance period for executive officers and key employees. Performance shares are valued at the fair value of the Company stock as of the grant date and expense is recognized based on the number of shares expected to vest under the terms of the award under which they are granted. Of these shares:


•	up to 50% will become payable only upon achievement of a financial performance goal relating to return on investment of capital for the performance period beginning January 1, 2016 and ending December 31, 2018; and


•	up to 50% will become payable only upon achievement of a performance goal relating to absolute sales growth for the performance period beginning January 1, 2016 and ending December 31, 2018.

As of April 3, 2016, there were up to 73,447 shares and 82,042 shares reserved for TSR awards for key employees for the fiscal year 2016-2018 and 2015-2017 performance periods, respectively. The Company used an integrated Monte Carlo simulation model to determine the fair value of the TSR awards. The Monte Carlo model calculates the probability of satisfying the market conditions stipulated in the award. This probability is an input into the trinomial lattice model used to determine the fair value of the awards as well as the assumptions of other variables, including the risk-free interest rate and expected volatility of the Company's stock price in future periods. The risk-free rate is based on the U.S. dollar-denominated U.S. Treasury strip rate with a remaining term that approximates the life assumed at the date of grant. There were 73,447 TSR awards granted during the quarter ended April 3, 2016 with a fair value of $87.85 per share.

(Amounts in thousands except share and per share data, unless otherwise indicated)

Restricted stock granted to non-employee directors and certain key employees totaled 153,815 shares during the quarter ended April 3, 2016. Restricted shares vest over periods generally ranging from one to three years from the date of award and are valued at the fair value of the Company's common stock as of the grant date.

Stock options may be granted periodically, with an exercise price equal to the fair market value of the Company's common stock on the date of grant, and generally vest from one to three years from the date of grant. Options are generally granted with seven-year or ten-year terms. The weighted-average fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model and represents the difference between fair market value on the date of grant and the estimated market value on the expected exercise date. The option pricing model requires the Company to make assumptions. The risk-free rate is based on U.S. Treasury zero-coupon issues with a remaining term that approximates the expected life assumed at the date of grant. Expected volatility is based on the historical volatility of the Company's stock over the past seven years. The expected option life is based on the contractual term of the stock option and expected employee exercise and post-vesting employment termination trends. There were 73,100 stock options granted during the quarter ended March 31, 2015 with a weighted average fair value of $39.81 per stock option. There were 72,328 stock options granted during the quarter ended April 3, 2016 with a weighted average fair value of $20.53 per stock option.

16. Contingencies

Litigation. From time to time, the Company is subject to various legal proceedings, including lawsuits, which arise out of, and are incidental to, the conduct of the Company's business. The Company does not consider any of such proceedings that are currently pending, individually or in the aggregate, notwithstanding that the unfavorable resolution of any matter may have a material effect on net earnings in any particular quarter, to be material to its business or likely to result in a material adverse effect on its operating results, financial condition or cash flows.

U.S. Government Investigations. The Company is also subject to U.S. Government investigations from which civil, criminal or administrative proceedings could result. Such proceedings could involve claims by the U.S. Government for fines, penalties, compensatory and treble damages, restitution and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. The Company believes, based upon all available information, that the outcome of any such pending government investigations will not have a material adverse effect on its operating results, financial condition or cash flows.

Claim Recovery. Profits expected to be realized on contracts are based on management's estimates of total contract sales value and costs at completion. Estimated amounts for contract changes and claims are included in contract sales only when realization is estimated to be probable. At April 3, 2016, based on progress to date on certain contracts, there was approximately $26,747 included in unbilled receivables for contract claims compared to $25,042 as of December 31, 2015.

Environmental Liabilities. The Company's operations and ownership or use of real property are subject to a number of federal, state, and local environmental laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites and restoration of damage to the environment. At certain sites that the Company owns or operates or formerly owned or operated, there is known or potential contamination that the Company is required to investigate or remediate. The Company could incur substantial costs, including remediation costs, resource restoration costs, fines, and penalties, or third party property damage or personal injury claims, as a result of liabilities associated with past practices or violations of environmental laws or noncompliance with environmental permits.

The Company has been identified as a potentially responsible party ("PRP"), along with other parties, in several regulatory agency actions associated with hazardous waste sites. As a PRP, the Company may be required to pay a share of the costs of the investigation and clean-up of these sites. While uncertainties exist with respect to the amounts and timing of the ultimate environmental liabilities, based on currently available information, the Company has concluded that these matters, individually or in the aggregate, will not have a material adverse effect on the Company's operating results, financial condition or cash flows.

The Company could incur substantial costs, including cleanup costs, resources restoration, fines and penalties or third party property damage or personal injury claims, as a result of violations or liabilities under environmental laws or noncompliance with environmental permits. While environmental laws and regulations have not had a material adverse effect on the Company's operating results, financial condition, or cash flows in the past and the Company has environmental management programs in place to mitigate these risks, it is difficult to predict whether they will have a material impact in the future.

(Amounts in thousands except share and per share data, unless otherwise indicated)

The liability for environmental remediation represents management's best estimate of the present value of the probable and reasonably estimable costs related to known remediation obligations. The receivable represents the present value of the amount that the Company expects to recover, as discussed below. Both the liability and receivable have been discounted to reflect the present value of the expected future cash flows, using a discount rate of 0.4% and 0.7% as of April 3, 2016 and December 31, 2015, respectively. The Company's discount rate is calculated using the 20-year Treasury constant maturities rate, net of an estimated inflationary factor of 1.9%, rounded to the nearest quarter percent.

The following is a summary of the amounts recorded for environmental remediation:



	April 3, 2016						December 31, 2015
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(42,921	)	$	18,675		$	(41,824	)	$	18,236
Unamortized discount	920			(286		)	1,718			(568		)
Present value amounts (payable) receivable	$	(42,001	)	$	18,389		$	(40,106	)	$	17,668

Amounts expected to be paid or received in periods more than one year from the balance sheet date are classified as noncurrent. Of the $42,001 discounted liability as of April 3, 2016, $5,323 was recorded within other current liabilities and $36,678 was recorded within other long-term liabilities. Of the $18,389 discounted receivable, the Company recorded $2,836 within other current assets and $15,553 within other noncurrent assets. As of April 3, 2016, the estimated discounted range of reasonably possible costs of environmental remediation was $42,001 to $80,536.

The Company expects that a portion of its environmental compliance and remediation costs will be recoverable under U.S. Government contracts. Some of the remediation costs that are not recoverable from the U.S. Government that are associated with facilities purchased in a business acquisition may be covered by various indemnification agreements, as described in Note 14 to the audited consolidated financial statements included in the Company’s Amended Transition Report on Form 10-K/A for the nine-month transition period ended December 31, 2015.

17. Share Repurchases

On March 11, 2015, the Company's Board of Directors authorized the Company to repurchase up to the lesser of $75,000 or 1.0 million shares of its common stock through December 31, 2015. On August 4, 2015, the Board of Directors increased the amount authorized for repurchase to the lesser of $100,000 or 1.4 million shares of the Company's common stock. On October 29, 2015, the Board of Directors increased the amount authorized for repurchase to the lesser of $250,000 or 3.25 million shares through December 31, 2016. Under the authorized repurchase program, shares of the Company common stock may be purchased from time to time in the open market, subject to compliance with applicable laws and regulations and the Company’s debt covenants, depending upon market conditions and other factors. The Company repurchased 334,101 shares for $27,402 during the quarter ended April 3, 2016.

In accordance with the Transaction Agreement entered into on April 28, 2014, the Company did not repurchase any outstanding shares prior to the closing of the Distribution and Merger during the quarter ended March 31, 2015.

18. Changes in Estimates

The majority of our sales are accounted for as long-term contracts, which are accounted for using the percentage-of-completion method ("POC"). Accounting for contracts under POC requires judgment relative to assessing risks and estimating contract revenues and costs. Profits expected to be realized on contracts are based on management’s estimates of total contract sales value and costs at completion. Estimated amounts for contract changes, including scope and claims, are included in contract sales only when realization is probable. Assumptions used for recording sales and earnings are modified in the period of change to reflect revisions in contract value and estimated costs. In the period in which it is determined that a loss will be incurred on a contract, the entire amount of the estimated loss, based on gross profit along with general and administrative costs, is charged to cost of sales. Changes in estimates of contract value, costs or profits are recognized using the cumulative catch-up method of accounting. Changes in estimates of contract value, costs or profits are recognized using the cumulative catch-up method of accounting. The cumulative effect of a change in estimate is recognized in the period a change in estimate occurs.

(Amounts in thousands except share and per share data, unless otherwise indicated)

Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by approximately $29 million (as restated) and $39 million (as restated) for the quarters ended April 3, 2016 and March 31, 2015, respectively. The aggregate net changes in contract estimates are reflective of the correction in accounting policy for determining a forward loss and any other resulting impact from the errors being corrected in the Restatement (see Note 3). The changes in estimates for the quarter ended April 3, 2016 are primarily attributable to higher profit expectations in the Flight Systems Group and the Space Systems Group. The adjustments for the quarter ended March 31, 2015 were primarily due to profit margin improvements in the Flight Systems Group and Defense Systems Group. Estimated costs to complete on loss contracts at April 3, 2016 and December 31, 2015 were $1,410,564 and $1,392,218, respectively.

19. Restructuring Costs

The Company had restructuring liabilities for termination benefits of $1,994 and $3,589 and facility related liabilities of $24,166 (as restated) and $26,154 (as restated) for the quarters ended April 3, 2016 and December 31, 2015, respectively. The change in restructuring liabilities for the quarter ending April 3, 2016, was primarily attributed to cash expenditures for termination benefits and facilities.

20. Operating Segment Information

The Company operates its business structure within three operating segments. These operating segments ("groups") are defined based on the reporting and review process used by the Company's chief executive officer and other management.

Certain administrative functions are primarily managed by the Company at the corporate headquarters ("Corporate"). Some examples of such functions are human resources, pension and postretirement benefits, corporate accounting, legal, tax and treasury. Significant assets and liabilities managed at Corporate include those associated with debt, restructuring, pension and postretirement benefits, environmental liabilities, litigation liabilities, strategic growth costs and income taxes.

Costs related to the administrative functions managed by Corporate are either recorded at Corporate or allocated to the business units based on the nature of the expense. The difference between pension and postretirement benefit expense calculated under U.S. Generally Accepted Accounting Standards ("U.S. GAAP") and the expense calculated under U.S. Cost Accounting Standards is recorded at the corporate level which provides for greater clarity on the operating results of the business segments. Administrative expenses such as corporate accounting, legal and treasury costs are allocated out to the business segments. Environmental expenses are allocated to each segment based on the origin of the underlying environmental cost. Transactions between segments are recorded at the segment level, consistent with the Company's financial accounting

The amortization expense related to purchase accounting attributed to the acquisition of Orbital is also recorded in Corporate.

21. Subsequent Events

As a result of the Restatement, the Company was unable to file its Quarterly Reports on Form 10-Q with the SEC for the fiscal quarters ended July 3, 2016 and October 2, 2016 ("the 2016 Quarterly Reports") as well as its Annual Report on Form 10-K for 2016. The Company has entered into an extension agreement with its Senior Credit Facility lender group to extend, until April 14, 2017, the deadline under the Senior Credit Facility for filing with the SEC the 2016 Quarterly Reports, as well as this Form 10-Q/A for the fiscal quarter ended April 3, 2016 and the Company's Annual Report on Form 10-K for 2016. As a result of the extension, the Company is in compliance with the financial covenants as of the date of the filing of this Form 10-Q/A based on the Company's restated financial results.

Securities Class Action. On August 12, 2016, a putative class action complaint, naming the Company, our Chief Executive Officer and our Chief Financial Officer as defendants, was filed in the United States District Court for the Eastern District of Virginia (Steven Knurr v. Orbital ATK, Inc., et al., No. 16-cv-01031 (TSE-MSN)). The class action complaint asserts claims on behalf of purchasers of Orbital securities for violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, arising out of allegedly false and misleading statements and the failure to disclose that: (i) the Company lacked effective control over financial reporting; and (ii) as a result, the Company failed to record an anticipated loss on its long-term contract with the U.S. Army to manufacture and supply small caliber ammunition at the U.S. Army’s Lake City Army Ammunition Plant. The complaint seeks a determination that this matter is a proper class action and certifying the plaintiff as the class representative, an award of damages, an award of reasonable costs and expenses of trial, including counsel and expert fees, and an award of such other relief as deemed appropriate by the Court. The Company intends to defend this action vigorously.

SEC Investigation. The SEC is conducting a non-public investigation relating to our historical accounting practices as a result of the prior restatement of the Company’s unaudited condensed consolidated financial statements for the quarterly periods ended July 5, 2015 and October 4, 2015 as described in the Company's Transition Report on Form 10-K for the nine-month transition period ending December 31, 2015 filed on March 15, 2016. The Company has also voluntarily self-reported to the SEC regarding matters pertaining to the Restatement described in the Form 10-K/A. The Company is cooperating fully with the SEC in connection with these matters.

Critical Accounting Policies

The Company’s significant accounting policies are described in Note 1 to the consolidated financial statements included in the Company’s Form 10-K/A and the same accounting policies are used in preparing the Company’s interim condensed consolidated financial statements.

In preparing the condensed consolidated financial statements, the Company follows accounting principles generally accepted in the United States. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, sales, expenses, and related disclosure of contingent assets and liabilities. The Company re-evaluates its estimates on an on-going basis. The Company’s estimates are based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions.

More information on these policies can be found in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the Company’s Form 10-K/A.

Results of Operations (as restated)

The following information should be read in conjunction with our condensed consolidated financial statements. The key performance indicators that management uses in managing the business are sales, income before interest and income taxes, and cash flows.

Table of Contents

Group Sales, Cost of Sales, and Income from Continuing Operations before Interest, Income Taxes and Noncontrolling Interest include intergroup sales and profit. Corporate and Eliminations include intergroup sales and profit eliminations and corporate expenses.

As a general note, results for the quarter ended April 3, 2016 include Orbital for the full quarter, whereas results for the quarter ended March 31, 2015 include Orbital only after the Merger date of February 9, 2015.

Sales (as restated)



	Quarter Ended
	April 3, 2016			March 31, 2015			Change			Percent Change
Flight Systems Group	$	353,956		$	327,334		$	26,622		8.1	%
Defense Systems Group	430,693			499,544			(68,851		)	(13.8	)%
Space Systems Group	285,754			188,102			97,652			51.9	%
Corporate and Eliminations	(14,008		)	(43,830		)	29,822			68.0	%
Total sales	$	1,056,395		$	971,150		$	85,245		8.8	%

Fluctuations in sales were driven by program-related changes within the operating segments and the impact of the Merger as described below.

Flight Systems Group. The increase in sales was primarily due to the Merger. Sales for the quarter ended April 3, 2016 include Orbital's former Launch Vehicles segment, now referred to as the Launch Vehicles division, for the full quarter; however, sales for the quarter ended March 31, 2015 include the results of the Launch Vehicles division only after the Merger date. Launch Vehicles division sales were $131,000 for the quarter ended April 3, 2016, compared to $64,700 for the quarter ended March 31, 2015. This increase in sales was partially offset by a decrease in Propulsion Systems sales largely due to the termination in 2015 of a commercial contract.

Defense Systems Group. The decrease in sales was primarily due to reductions in shipments of Armament Systems Division products.

Space Systems Group. The increase in sales was primarily due to the Merger. Sales for the quarter ended April 3, 2016 include Orbital's former Advanced Space Programs and Satellite and Space Systems segments for the full quarter; however, sales for the quarter ended March 31, 2015 include the results of those former Orbital segments only after the Merger date. The legacy Orbital businesses generated sales of approximately $242,900 for the quarter ended April 3, 2016, compared to $119,300 included in our results for the quarter ended March 31, 2015.

Corporate. The change in eliminations was driven primarily by lower intergroup sales from Defense Systems Group, due to the spin-off of Vista Outdoor as a result of the Distribution.

Total cost of sales	$	829,560		$	747,877		$	81,683		10.9	%

The fluctuation in cost of sales was driven by program-related changes within the operating segments and the impact of the Merger as described below.

Flight Systems Group. The increase in cost of sales was primarily due to the Merger. Cost of sales for the quarter ended April 3, 2016 include Orbital's former Launch Vehicles segment, now referred to as the Launch Vehicles division, for the full quarter; however, cost of sales for the quarter ended March 31, 2015 include the results of the Launch Vehicles division only after the Merger date. Launch Vehicles division cost of sales were $101,600 for the quarter ended April 3, 2016, compared to

Table of Contents

$47,500 for the quarter ended March 31, 2015. This increase in cost of sales was partially offset by a decrease in Propulsion Systems cost of sales largely due to the 2015 termination of a commercial contract.

Defense Systems Group. The decrease in cost of sales was primarily driven by reduced cost of sales in Armament Systems that reflected decreased foreign sales.

Space Systems Group. The increase in cost of sales was primarily due to the Merger. Cost of sales for the quarter ended April 3, 2016 include Orbital's former Advanced Space Programs and Satellite and Space Systems segments for the full quarter; however, sales for the quarter ended March 31, 2015 include the results of those former Orbital segments only after the Merger date. The legacy Orbital businesses incurred cost of sales of approximately $196,000 for the quarter ended April 3, 2016, compared to $101,700 for the quarter ended March 31, 2015.

Corporate. The change in corporate/eliminations was driven primarily by lower intergroup sales from Defense Systems Group, due to the spin-off of Vista Outdoor in the Distribution.

Operating Expenses (as restated)

Operating expenses decreased $113,308 in the quarter ended April 3, 2016 compared to the quarter ended March 31, 2015 primarily due to $18,000 of transaction costs pertaining to the Merger and Distribution, $15,000 of restructuring charges, a $25,000 charge related to a lawsuit settlement and a goodwill impairment charge of $34,300 in the quarter ended March 31, 2015.

Income from Continuing Operations, Before Interest, Income Taxes and Noncontrolling Interest (as restated)



	Quarter Ended
	April 3, 2016			March 31, 2015			Change
Flight Systems Group	$	49,695		$	41,731		$	7,964
Defense Systems Group	42,125			57,437			(15,312		)
Space Systems Group	29,832			(20,707		)	50,539
Corporate/Eliminations	(1,173		)	(74,852		)	73,679
Total	$	120,479		$	3,609		$	116,870

The fluctuations in income from continuing operations, before interest, income taxes and noncontrolling interest are described as follows:

Flight Systems Group. The increase in income was primarily due to the Merger. Income for the quarter ended April 3, 2016 include Orbital's former Launch Vehicles segment, now referred to as the Launch Vehicles division, for the full quarter; however, income for the quarter ended March 31, 2015 include the results of the Launch Vehicles division only after the Merger date. In addition, income for the quarter ended April 3, 2016 included the impact of a favorable change in estimated profit adjustment associated with our CRS contract.

Defense Systems Group. The decrease in income was largely due to lower revenues and unfavorable product mix in the Armament Systems Division.

Space Systems Group. The increase in income was primarily due to the Merger. Income for the quarter ended April 3, 2016 included Orbital's former Advanced Space Programs and Satellite and Space Systems segments in our results for the full quarter; however, income for the quarter ended March 31, 2015 include the results of these former Orbital segments only after the Merger date. In addition, income for the quarter ended April 3, 2016 included the impact of a favorable change in estimated profit adjustment associated with our CRS contract.

Table of Contents

Corporate. Results reflect unallocated expenses incurred for administrative functions that are performed centrally at the corporate headquarters, the difference between pension and postretirement benefit expense calculated under U.S Generally Accepted Accounting Standards ("U.S GAAP") and the expense calculated under U.S. Cost Accounting Standards ("CAS"), merger and acquisition transaction related costs, amortization of intangible assets recorded in connection with the Merger, and the elimination of intercompany profits. The decrease in corporate expenses in the quarter ended April 3, 2016 compared to the quarter ended March 31, 2015 was largely driven by $18,000 of transaction costs pertaining to the Merger and Distribution, $15,000 of restructuring charges and a goodwill impairment charge of $34,300 recorded in the quarter ended March 31, 2015.

Changes in Estimates. The majority of our sales are accounted for as long-term contracts, which are accounted for using the percentage-of-completion method ("POC"). Accounting for contracts under POC requires judgment relative to assessing risks and estimating contract revenues and costs. Profits expected to be realized on contracts are based on management’s estimates of total contract sales value and costs at completion. Estimated amounts for contract changes, including scope and claims, are included in contract sales only when realization is probable. Assumptions used for recording sales and earnings are modified in the period of change to reflect revisions in contract value and estimated costs. In the period in which it is determined that a loss will be incurred on a contract, the entire amount of the estimated gross margin loss is charged to cost of sales. Changes in estimates of contract sales, costs or profits are recognized using the cumulative catch-up method of accounting. This method recognizes in the current period the cumulative effect of the changes on current or prior periods. The effect of the changes on future periods of contract performance is recognized as if the revised estimate had been used since contract inception.

Changes in contract estimates occur for a variety of reasons including changes in contract scope, unforeseen changes in contract cost estimates due to unanticipated cost growth or risks affecting contract costs and/or the resolution of contract risks at lower costs than anticipated, as well as changes in contract overhead costs over the performance period. Changes in estimates could have a material effect on our consolidated financial position or annual results of operations. Aggregate net changes in contract estimates recognized using the cumulative catch-up method of accounting increased operating income by approximately $29 million and $39 million for the quarters ended April 3, 2016 and March 31, 2015, respectively. The changes in estimates for the quarter ended April 3, 2016 are primarily attributable to higher profit expectations in the Flight Systems Group and the Space Systems Group. The adjustments for the quarter ended March 31, 2015 were primarily due to profit margin improvements in Flight Systems Group and Defense Systems Group.

Net Interest Expense (as restated)

Net interest expense for the quarter ended April 3, 2016 was $17,312 (as restated) a decrease of $3,439 (as restated) compared to $20,751 (as restated) in the quarter ended March 31, 2015.

Income Taxes (from Continuing Operations) (as restated)



	Quarter Ended
	April 3, 2016		Effective Rate		March 31, 2015			Effective Rate		Change
Income taxes	$	25,894	25.1	%	$	(4,223	)	9.6	%	$	30,117

The effective income tax rate for the tax expense in the quarter ended April 3, 2016 was 25.1% compared to an effective income tax rate of 9.6% for the tax benefit in the quarter ended March 31, 2015, reflecting the impact of domestic manufacturing deductions and research and development tax credits in the quarter ended April 3, 2016 and the impact of certain non-deductible costs in the quarter ended March 31, 2015.

Income From Continuing Operations, Before Noncontrolling Interest (as restated)

Net income from continuing operations before noncontrolling interest for the quarter ended April 3, 2016 was $77,273, an increase of $116,818 compared to $(39,545) in the quarter ended March 31, 2015.

Liquidity and Capital Resources

We manage our business to maximize operating cash flows as the primary source of liquidity. In addition to cash on hand and cash generated by operations, sources of liquidity include a credit facility, long-term borrowings, and access to the public debt and equity markets. We use our cash to fund investments in our existing core businesses and for debt repayment, cash dividends, share repurchases, acquisitions and other activities.

Table of Contents

Cash Flows Summary (as restated)

Our cash flows from continuing operations for operating, investing and financing activities, as reflected in the condensed consolidated statements of cash flows are summarized as follows:



	Quarter Ended
	April 3, 2016			March 31, 2015
Cash (used for) provided by operating activities of continuing operations	$	(75,071	)	$	146,404
Cash (used for) provided by investing activities of continuing operations	(22,573		)	391,401
Cash provided by (used for) financing activities of continuing operations	67,136			(520,922		)
Net cash flows from continuing operations	$	(30,508	)	$	16,883

Operating Activities (as restated)

Cash used for operating activities of continuing operations during the quarter ended April 3, 2016 was $75,071, compared to cash provided by operating activities of $146,404 during the quarter ended March 31, 2015. The decrease in operating cash flow resulted primarily from the net effect of changes in working capital and other assets and liabilities partially offset by a $116,818 improvement in the income (loss) from continuing operations. During the quarter ended April 3, 2016, changes in working capital and other assets and liabilities used $202,567 of cash, comprised of a $178,590 increase in net receivables, a $22,009 increase in inventories, a $13,571 decrease in accrued compensation, a $11,949 decrease in contract loss reserve and a $46,526 change in other assets and liabilities, offset by a $43,134 increase in accounts payable, a $20,079 decrease in income taxes receivable and a $6,865 increase in pension and other postretirement benefits. During the quarter ended March 31, 2015, changes in working capital and other assets and liabilities provided $94,453 of cash, comprised of a $113,723 decrease in net receivables, a $15,847 decrease in inventories, a $5,973 decrease in income taxes receivable and a $32,199 change in other assets and liabilities, offset by a $31,869 decrease in accounts payable, a $17,550 decrease in contract loss reserve, a $15,610 decrease in pension and other postretirement benefits and a $8,260 decrease in accrued compensation.

Investing Activities

Cash used for investing activities of continuing operations during the quarter ended April 3, 2016 was $22,573, compared to cash provided by investing activities during the quarter ended March 31, 2015 of $391,401. Capital expenditures during the quarter ended April 3, 2016 were $22,573, compared to $51,343 during the quarter ended March 31, 2015. Cash provided by investing activities during the quarter ended March 31, 2015 included $253,734 of cash acquired in the Merger with Orbital and a cash dividend of $188,878 received from Vista Outdoor in conjunction with the distribution of Sporting Group.

Financing Activities

Cash provided by financing activities during the quarter ended April 3, 2016 was $67,136, compared to cash used for financing during the quarter ended March 31, 2015 of $520,922. The decrease in cash used for financing activities was largely attributable to debt extinguishment payments of $372,758 made during the quarter ended March 31, 2015.

Liquidity

In addition to our normal operating cash requirements, our principal future cash requirements will be to fund capital expenditures, repay debt, satisfy employee benefit obligations, repurchase shares, pay dividends and complete any strategic acquisitions. Our short-term cash requirements for operations are expected to consist mainly of capital expenditures to maintain and expand production facilities and working capital requirements. Our debt service requirements over the next two years consist of principal payments due under the Senior Credit Facility, as discussed further below. Our other debt service requirements consist of interest expense on our debt.

During the quarter ended April 3, 2016, we paid dividends totaling $17,590. On May 3, 2016, the Board of Directors declared a dividend of $0.30 per share payable on June 23, 2016 to holders of record on June 8, 2016. The payment and amount of any future dividends are at the discretion of our Board of Directors and will be based on a number of factors, including our earnings, liquidity position, financial condition, capital requirements, credit ratings and the availability and cost of obtaining new debt. We cannot be certain that we will continue to declare dividends in the future and, as such, the amount and timing of any future dividends are not determinable.

Based on our current financial condition, we believe our cash position, combined with anticipated generation of cash flows, as well as the availability of funding, if needed, through our Senior Credit Facility, access to debt and equity markets, and potential future sources of funding such as additional bank financing and debt markets, will be adequate to fund future

Table of Contents

growth as well as service our anticipated long-term debt and pension obligations, make capital expenditures and pay dividends over the next 12 months.

We do not expect our access to liquidity sources will be materially impacted in the near future. There can be no assurance, however, that the cost or availability of future borrowings, if any, will not be materially impacted by capital market conditions.

Long-term Debt and Credit Facilities

As of April 3, 2016, we had outstanding total indebtedness of $1,605,000 and a $1,000,000 revolving credit facility provided for the potential of additional borrowings up to $744,684 reduced by outstanding borrowings of $125,000 and letters of credit of $130,316.

See Note 12 "Long-term Debt" to the condensed consolidated financial statements in Part I, Item 1 for a detailed discussion of these borrowings.

Covenants

As of April 3, 2016, we were in compliance with all of the covenants in our debt agreements, including specified financial ratios that our Senior Credit Facility requires us to meet as follows:



	Total Leverage Ratio ⁽¹⁾	Interest Coverage Ratio ⁽²⁾
Requirement	4.00	3.00
Actual at April 3, 2016 (as restated)	2.53	9.07
⁽¹⁾ Not to exceed the required financial ratio
⁽²⁾ Not to be below the required financial ratio

The Total Leverage Ratio is the sum of our total debt plus financial letters of credit, net of up to $100,000 of cash, divided by Covenant EBITDA (which includes adjustments for items such as non-recurring or extraordinary non-cash items, non-cash charges related to stock-based compensation, and intangible asset impairment charges, as well as inclusion of EBITDA of acquired companies on a pro forma basis) for the past four fiscal quarters.

See Note 12 "Long-term Debt" to the condensed consolidated financial statements in Part I, Item 1 for further discussion of the covenants in our debt agreements.

Our debt agreements contain cross-default provisions so that non-compliance with the covenants within one debt agreement could cause a default under other debt agreements as well. Our ability to comply with these covenants in the future and to meet and maintain the requisite financial ratios may be affected by events beyond our control.

Impact of the Restatement on Covenants

As a result of the Restatement, the Company was unable to file its Quarterly Reports on Form 10-Q with the SEC for the fiscal quarters ended July 3, 2016 and October 2, 2016 ("the 2016 Quarterly Reports") as well as its Annual Report on Form 10-K for 2016. The Company has entered into an extension agreement with its Senior Credit Facility lender group to extend, until April 14, 2017, the deadline under the Senior Credit Facility for filing with the SEC the 2016 Quarterly Reports as well as the Company's Annual Report on Form 10-K for 2016. As a result of the extension, the Company is in compliance with the financial covenants as of the date of the filing of this Form 10-Q/A based on the Company's restated financial results.

Share Repurchases

On March 11, 2015, our Board of Directors authorized us to repurchase up to the lesser of $75 million or 1.0 million shares of our common stock through December 31, 2015. On August 4, 2015, the Board of Directors increased the amount authorized for repurchase to the lesser of $100 million or 1.4 million shares. On October 29, 2015, the Board of Directors increased the amount authorized for repurchase to the lesser of $250 million or 3.25 million shares through December 31, 2016. Under the authorized repurchase program, shares of our common stock may be purchased from time to time in the open market, subject to compliance with applicable laws and regulations and our debt covenants, depending upon market conditions and other factors. We repurchased 334,101 shares for $27,402 during the quarter ended April 3, 2016.

In accordance with the Transaction Agreement entered into on April 28, 2014, we did not repurchase any outstanding shares prior to the closing of the Distribution and Merger during the quarter ended March 31, 2015.

Authorized repurchases of our shares are subject to market conditions, our compliance with our debt covenants and the limitations imposed by the tax treatment of the Distribution and the related Tax Matters Agreement between us and Vista Outdoor. Our 5.25% Notes and 5.50% Notes limit the aggregate sum of dividends, share repurchases, and other designated restricted payments to an amount based on our net income, stock issuance proceeds, and certain other items since April 1, 2001, less restricted payments made since that date. As of April 3, 2016, the Senior Credit Facility allows us to make unlimited "restricted payments" (as defined in the Credit Agreement), which, among other items, allows payments for future share repurchases, as long as we maintain a certain amount of liquidity and maintain certain senior secured debt limits. When those requirements are not met, the limit is equal to $250,000 plus proceeds of any equity issuances plus 50% of net income since October 7, 2010. The Credit Agreement also prohibits dividend payments if loan defaults exist or the financial covenants contained in the agreement are not met.

Contractual Obligations and Commercial Commitments

There have been no material changes with respect to the contractual obligations and commitments or off-balance sheet arrangements described in our Form 10-K/A.

Contingencies

Environmental Liabilities. Our operations and ownership or use of real property are subject to a number of federal, state, and local environmental laws and regulations, as well as applicable foreign laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites and restoration of damage to the environment. At certain sites that we own or operate or formerly owned or operated, there is known or potential contamination that we are required to investigate or remediate. We could incur substantial costs, including remediation costs, resource restoration costs, fines, and penalties, or third party property damage or personal injury claims, as a result of liabilities associated with past practices or violations of environmental laws or non-compliance with environmental permits.

The liability for environmental remediation represents management's best estimate of the present value of the probable and reasonably estimable costs related to known remediation obligations. The receivable represents the present value of the amount that we expect to recover, as discussed below. Both the liability and receivable have been discounted to reflect the present value of the expected future cash flows, using a discount rate of 0.40% and 0.70% as of April 3, 2016 and December 31, 2015, respectively. Our discount rate is calculated using the 20-year Treasury constant maturities rate, net of an estimated inflationary factor of 1.9%, rounded to the nearest quarter percent.

Table of Contents

The following is a summary of the amounts recorded for environmental remediation:



	April 3, 2016						December 31, 2015
	Liability			Receivable			Liability			Receivable
Amounts (payable) receivable	$	(42,921	)	$	18,675		$	(41,824	)	$	18,236
Unamortized discount	920			(286		)	1,718			(568		)
Present value amounts (payable) receivable	$	(42,001	)	$	18,389		$	(40,106	)	$	17,668

As of April 3, 2016, the estimated discounted range of reasonably possible costs of environmental remediation was $42,001 to $80,536.

We expect that a portion of our environmental compliance and remediation costs will be recoverable under U.S. Government contracts. Some of the remediation costs that are not recoverable from the U.S. Government that are associated with facilities purchased in a business acquisition may be covered by various indemnification agreements, as described in Note 14 to the audited consolidated financial statements included in our Amended Transition Report on Form 10-K/A for the nine-month transition period ended December 31, 2015.

We have been identified as a potentially responsible party ("PRP"), along with other parties, in several regulatory agency actions associated with hazardous waste sites. As a PRP, we may be required to pay a share of the costs of the investigation and clean-up of these sites. While uncertainties exist with respect to the amounts and timing of the ultimate environmental liabilities, based on currently available information, we have concluded that these matters, individually or in the aggregate, will not have a material adverse effect on our operating results, financial condition or cash flows.

Other Contingencies. On August 12, 2016, a putative class action complaint, naming the Company, our Chief Executive Officer and our Chief Financial Officer as defendants, was filed in the United States District Court for the Eastern District of Virginia (Steven Knurr v. Orbital ATK, Inc., et al., No. 16-cv-01031 (TSE-MSN)). The class action complaint asserts claims on behalf of purchasers of Orbital securities for violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and Rule 10b-5 thereunder, arising out of allegedly false and misleading statements and the failure to disclose that: (i) the Company lacked effective control over financial reporting; and (ii) as a result, the Company failed to record an anticipated loss on its long-term contract with the U.S. Army to manufacture and supply small caliber ammunition at the U.S. Army’s Lake City Army Ammunition Plant. The complaint seeks a determination that this matter is a proper class action and certifying the plaintiff as the class representative, an award of damages, an award of reasonable costs and expenses of trial, including counsel and expert fees, and an award of such other relief as deemed appropriate by the Court. The Company intends to defend this action vigorously.

We are also subject to a number of other potential risks and contingencies. These risks and contingencies are described in Item 1A of Part I of our Form 10-K/A.

New Accounting Pronouncements

See Note 2 to the unaudited condensed consolidated financial statements in Item 1 of Part I of this report.

Inflation

In management's opinion, inflation has not had a significant impact upon the results of our operations. The selling prices under contracts, the majority of which are long term, generally include estimated costs to be incurred in future periods. These cost projections can generally be negotiated into new buys under fixed-price government contracts, while actual cost increases are recoverable on cost-type contracts.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

There were no material changes in our market risk during the quarter ended April 3, 2016. For additional information, refer to Item 7A of Part II of our Form 10-K/A.

ITEM 4. CONTROLS AND PROCEDURES

Internal Investigation

As described in the Explanatory Note to this Form 10-Q/A, we have restated our consolidated financial statements for the quarter ended April 3, 2016 and the corresponding comparative quarter ended March 31, 2015. For more information regarding the Restatement, see Note 3 "Restatement" of the notes to consolidated financial statements contained in Part I, Item 1, Financial Statements, in this Form 10-Q/A. Capitalized terms used in this Item 4 have been defined in Note 3 in the notes to the

Table of Contents

consolidated financial statements.

Based on the internal investigation, the Audit Committee and senior management concluded as follows: Certain personnel at the Small Caliber Systems Division and, in some cases, Defense Systems Group, acted inappropriately and failed to adhere to the high standards established in the Company’s policies and expected by senior management and the Board of Directors. Specifically, with respect to the Lake City Contract: (a) there likely was a bias toward maintaining a targeted profit rate; (b) in some cases, there appears to have been inappropriate use of management reserves to maintain the targeted profit rate; (c) some members of the Small Caliber Systems Division finance staff failed to follow up and inquire further into indicators that cost overruns were occurring, and if such inquiries had been made, it could have led to further contemporaneous discussion and an earlier conclusion that the Lake City Contract was in a forward loss position; and (d) negative information was suppressed, and concerns at the Small Caliber Systems Division about cost overruns were not escalated appropriately to higher-level Company management or finance staff, nor were they communicated to the Audit Committee, the Board of Directors or the independent registered public accounting firms. The Lake City Contract is in a forward loss position, which means that it will result in a net loss over its total contract life. In addition to the investigation findings above, the Company’s identification of the forward loss was also delayed by a number of other factors which obscured the actual performance of the Lake City Contract, including migration to a new plant-wide software system at LCAAP, the unionization of employees at the LCAAP, and other factors. In response to the findings of the internal investigation, the Company has taken and will continue to take significant and comprehensive remedial actions which are described below under “Remediation Efforts to Address Material Weaknesses.”

Disclosure Controls and Procedures

In connection with the filing of the Company’s Form 10-Q for the quarter ended April 3, 2016 on May 9, 2016 (the “Original Filing”), management of the Company, with the participation of its CEO and CFO, evaluated the effectiveness of the Company’s disclosure controls and procedures as of April 3, 2016. Based upon that evaluation, the Company’s CEO and CFO concluded that the Company’s disclosure controls and procedures were not effective as of April 3, 2016 because of the material weaknesses in our internal control over financial reporting that were identified in connection with the preparation of the Form 10-K for the for the nine-month transition period ended December 31, 2015 filed on March 15, 2016 (the “Original Form 10-K Filing”) which are described below and continued to exist as of April 3, 2016.

Subsequent to the evaluation made in connection with the Original Filing in May 2016 and in connection with the preparation and filing of this Form 10-Q/A, our CEO and CFO re-evaluated the effectiveness of the Company’s disclosure controls and procedures as of April 3, 2016. The re-evaluation concluded additional material weaknesses existed, which are described below.

Material Weaknesses Identified in the Original Filing

In connection with the evaluation of the effectiveness of our disclosure controls and procedures in the Original Filing, management identified material weaknesses in our control environment related to: (i) establishing and maintaining accounting policies and procedures related to complex transactions, and (ii) maintaining a sufficient complement of personnel with appropriate levels of accounting and controls knowledge, experience and training commensurate with the nature and complexity of our business and contract activity.

These material weaknesses in our control environment contributed to material weaknesses at the control activity level where we (iii) did not design appropriate controls to ensure completeness and accuracy of purchase accounting, specifically we did not maintain controls over measurement period adjustments and controls over the calculation of acquired contracts’ percentage of completion used to recognize revenue. In addition, we (iv) did not maintain controls over the integration of accounting operations of the two merged companies and over the preparation, analysis and review of accounts of the combined business.

Additional Material Weaknesses Identified Subsequent to the Original Filing

Subsequent to the evaluation of our disclosure controls and procedures in connection with the Original Filing and as part of management’s re-evaluation of our internal control over financial reporting in connection with preparing the Form 10-K/A, for the nine-month transition period ended December 31, 2015 filed on February 24, 2017 (the “Form 10-K/A”), management identified two additional material weaknesses in our internal control over financial reporting: (v) the Company did not maintain an effective control environment at our Defense Systems Group and its Small Caliber Systems Division. Specifically, the Small Caliber Systems Division did not maintain a control environment where procedures to escalate accounting issues to Defense Systems Group or Corporate management were followed, which led to the suppression of information by Small Caliber Systems Division management related to cost overruns and the override of certain controls due to pressure to achieve cost savings and maintain a targeted profit rate; and (vi) the material weakness in our control environment contributed to a material weakness at the Small Caliber Systems Division, where the Small Caliber Systems Division did not design and maintain controls related to the preparation, review and approval of costs incurred and contract estimates used to determine revenue.

As a result of these material weaknesses in our internal control over financial reporting which continued to exist as of April 3, 2016, our CEO and CFO re-affirmed the conclusion that our disclosure controls and procedures were not effective as of April 3, 2016.

Remediation Efforts to Address Material Weaknesses

Remediation to Address the Material Weaknesses Identified in the Original Filing

We are continuing to augment our accounting, finance and controls oversight functions with additional professionals to provide increased oversight, appropriate maintenance of policies and procedures related to complex transactions and integration of accounting operations and analysis of accounts of the combined business with particular focus on corporate personnel.

Further, we are performing an enterprise-wide controls improvement program for evaluation of controls across all significant locations utilizing a risk-based approach. We combined the two legacy companies’ control frameworks and validated that where a risk of a material misstatement existed, key controls were identified to address the risk. In addition, we have taken meaningful steps to implement a number of key controls and processes to increase the oversight of the Company’s multiple businesses. We have taken the following specific remediation initiatives in response to the material weaknesses identified in the Original Filing:

•Control Environment.

◦We evaluated our accounting organization and augmented our team with additional professionals with the appropriate levels of accounting and controls knowledge, experience and training. Our evaluation included benchmarking key accounting functions and resulted in the identification of a number of areas where the team needed to be augmented. As a result of this evaluation, we have hired 11 additional accounting and controls professionals in key areas of technical accounting, general accounting oversight, business unit accounting, external reporting and controls. Each of these 11 new professionals is a CPA and 9 of the 11 have experience with a “Big 4” accounting firm. We will continue to evaluate our accounting organization and augment the team as appropriate.

◦We revised our accounting policy for loss contracts to include general and administrative costs in the measurement of loss contracts.

◦We designed an enterprise-wide process to timely identify, track and appropriately resolve and conclude on complex transactions and disclosures.

•Control-Activity Level.

◦We redesigned, developed and implemented processes and controls over the execution of purchase accounting.

◦We revised our account reconciliation policy and controls, including the timing of reconciliations, thresholds for review and the process for resolving reconciling items. We continue to monitor the reconciliation control execution and will make further changes as necessary. In addition, we implemented an enhanced company-wide balance sheet

Table of Contents

review process to perform a more detailed analysis of accounts, including balance composition, fluctuation and trend analysis, which is performed at a segment level.

We believe the remediation steps outlined above have improved and will continue to improve the effectiveness of our internal control over financial reporting. While we have made meaningful progress on strengthening our internal controls relative to the original material weaknesses (i), (ii), and (iv) which were identified in the Original Filing, we have not fully tested all our remediation actions to verify the effectiveness of their design or operation.

Regarding material weakness (iii), which was identified in the Original Filing as a material weakness in our internal control over financial reporting, we have subsequently concluded that the Company completed the design and implementation of new purchase accounting controls, which have subsequently remediated material weakness (iii) during the quarter ended December 31, 2016.

Remediation to Address the Additional Material Weaknesses Identified Subsequent to the Original Filing

In addition to continuing to implement the remediation initiatives described above in response to the material weaknesses identified in the Original Filing, we are implementing the following remedial actions in response to the conduct and other factors that led to the Restatement, including actions to remediate the additional material weaknesses in internal control over financial reporting:

•Control Environment.

◦Certain Small Caliber Systems Division personnel responsible for the inappropriate behaviors described under “Internal Investigation” above are no longer employed by the Company. In addition, certain members of the Defense Systems Group leadership will receive appropriate training, adverse compensation action and additional supervision.

◦Additional accounting, controls and financial reporting personnel have been added to the Small Caliber Systems Division to take responsibility for its financial data forming part of the basis for preparation of these restated consolidated financial statements.

◦We are increasing communication and training to employees regarding internal control over financial reporting, disclosure controls and procedures, and emphasizing the importance of adherence to our policies and procedures.

•Control Activity-Level.

◦We completed a detailed review of the Lake City Contract and the underlying estimates for its percentage of completion revenue recognition accounting model and developed extensive analysis and procedures to develop our management estimates going forward.

◦We are designing and implementing enhancements to the internal controls related to the reconciliation and analysis of unbilled accounts receivable.

The Board of Directors and management believe that the Company’s remediation actions will provide an appropriate control environment going forward once the material weaknesses disclosed herein are remediated and other actions described herein have been taken.

While we have taken measures to strengthen our internal controls related to these additional material weaknesses, we have not fully completed our assessment of these additional controls.

As our management continues to evaluate and work to improve our disclosure controls and procedures and internal control over financial reporting, we may determine to take additional measures to address these deficiencies or determine to modify certain of the remediation measures described above.

Changes in Internal Control over Financial Reporting

During the quarter ended April 3, 2016 there were no changes in the Company’s internal control over financial reporting (as defined in Rule 13a-15(f) under the Securities Exchange Act of 1934) that have materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II—OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

From time to time, we are subject to various legal proceedings, including lawsuits, which arise out of, and are incidental to, the conduct of our business.

Putative class action and derivative lawsuits challenging the merger of Orbital and our company were filed in the Court of Chancery of the State of Delaware in May 2014, naming Orbital, our company and Orbital's directors. On November 14, 2014, the lawsuits were consolidated by the court under the caption In Re Orbital Corporation Stockholder Litigation. The plaintiffs alleged, among other things, that the directors of Orbital breached their fiduciary duties in connection with the Merger, and alleged that we aided and abetted such breaches of fiduciary duty. On January 16, 2015, the parties entered into a memorandum of understanding (the “MOU”) regarding the settlement of this matter. Pursuant to the terms of the MOU, we and Orbital made additional information available to Orbital's stockholders in connection with the Merger vote. On February 2, 2016, the case was dismissed.

Environmental Liabilities. Our operations and ownership or use of real property are subject to a number of federal, state, and local laws and regulations, including those for discharge of hazardous materials, remediation of contaminated sites, and restoration of damage to the environment. Due in part to their complexity and pervasiveness, such laws and regulations have resulted in our company being involved with a number of related legal proceedings, claims and remediation obligations. We routinely assess, based on in-depth studies, expert analyses and legal reviews, our contingencies, obligations, and commitments for remediation of contaminated sites and past practices, including assessments of ranges and probabilities of recoveries from other responsible parties. Our policy is to accrue and charge to expense in the current period any identified exposures related to environmental liabilities based on estimates of investigation, cleanup, monitoring and resource restoration costs to be incurred.

We could incur substantial costs, including cleanup costs, resource restoration, fines, and penalties or third-party property damage or personal injury claims, as a result of violations or liabilities under environmental laws or noncompliance with environmental permits. While environmental laws and regulations have not had a material adverse effect on our operating results, financial condition or cash flows in the past, and we have environmental management programs in place to mitigate these risks, it is difficult to predict whether they will have a material impact in the future.

The description of certain environmental matters contained in Part I, Item 2, "Management’s Discussion and Analysis of Financial Condition and Results of Operations" under the heading "Contingencies," is incorporated herein by reference.

SEC Investigation. The SEC is conducting a non-public investigation relating to our historical accounting practices as a result of the prior restatement of the Company’s unaudited condensed consolidated financial statements for the quarterly periods ended July 5, 2015 and October 4, 2015 described in the original filing, and the Company also has voluntarily self-reported to the SEC regarding matters pertaining to the Restatement described in this Form 10-Q/A. The Company is cooperating fully with the SEC in connection with these matters.

Other U.S. Government Investigations. We are also subject to other U.S. Government investigations from which civil, criminal, or administrative proceedings could result. Such proceedings could involve claims by the U.S. Government for fines, penalties, compensatory and treble damages, restitution, and/or forfeitures. Under government regulations, a company, or one or more of its operating divisions or subdivisions, can also be suspended or debarred from government contracts, or lose its export privileges, based on the results of investigations. We believe, based upon all available information, that the outcome of any such pending government investigations will not have a material adverse effect on our operating results, financial condition, or cash flows.

The Company intends to defend this action vigorously.

ITEM 1A. RISK FACTORS

While our attempts to identify, manage and mitigate risks and uncertainties associated with our business to the extent practical under the circumstances, some level of risk and uncertainty will always be present. Item 1A of Part I of our Amended to the Transition Report on Form 10-K/A for the nine-month transition period ended December 31, 2015 describes all known material risks and uncertainties associated with our business. These risks and uncertainties have the potential to materially affect our business, financial condition, results of operations, cash flows, projected results and future prospects.
