ATK (NYSE: ATK) today announced the commencement of a cash tender offer (the “Tender Offer”) for any and all of the $195,951,000 aggregate principal amount of its outstanding 3.00% Convertible Senior Subordinated Notes due 2024 (CUSIP No. 018804AK0) (the “Notes”).
The Tender Offer will expire at midnight, New York City time, on June 27, 2014 (as such time and date may be extended, the “Expiration Date”), unless extended or earlier terminated by ATK in its sole discretion. Notes tendered may be withdrawn at any time at or prior to midnight, New York City time, at the end of the Expiration Date. The Tender Offer is not subject to any minimum tender condition, but is subject to a financing condition and certain other conditions summarized in the Offer to Purchase.

“We are confident in our business performance for Fiscal Year 2015,” said ATK President and Chief Executive Officer Mark DeYoung. “While we are obligated to settle these notes before the anticipated completion of the Orbital Sciences transaction, taking this action now reaffirms our expectation of delivering operational excellence, earnings growth, and shareholder value this year. We expect the retirement of the Notes will be accretive to earnings per share for the full fiscal year.”

Upon the terms and subject to the conditions of the Tender Offer, holders of Notes who validly tender and do not validly withdraw their Notes at or prior to midnight, New York City time, at the end of the Expiration Date, and whose Notes are accepted for purchase will receive, for each $1,000 principal amount of such Notes, a cash purchase price (the “Purchase Price”) equal to the sum of (i) the Average Volume-Weighted Average Price (the “Average VWAP”, as defined below and as specified in more detail in the Offer to Purchase) multiplied by 13.1023 (the current conversion rate of the Notes) plus (ii) an amount equal to the amount of interest that would accrue on such Notes from and including the settlement date to but excluding August 20, 2014, which is the first day that the Company may redeem the Notes, plus (iii) a fixed cash amount of $2.50, provided that in no event will the Purchase Price be less than $1,382.41 or more than $1,906.50 per $1,000 principal amount of such Notes. In addition to the Purchase Price, holders will receive, in respect of their Notes that are accepted for purchase, accrued and unpaid interest on such Notes to, but excluding, the settlement date of the Tender Offer. All amounts payable pursuant to the Tender Offer will be rounded to the nearest cent.

In addition to the Tender Offer, in connection with a dividend the Company has declared and will pay to holders of its outstanding common stock during the pendency of the Tender Offer, the Company intends to make a payment to each holder of Notes who is a holder of record at the close of business on June 2, 2014 (the record date of such dividend), on the date of payment of such dividend (which is expected to be June 26, 2014), for each $1,000 principal amount of Notes held by such holder, in an amount equal to the per share amount of such dividend, multiplied by 13.1023, such that the holders of the Notes will effectively participate in the dividend without conversion of their Notes. As a result of such payment, no anti-dilution adjustment to the conversion rate of the Notes will be made as a result of this dividend.

“Average VWAP” is the simple arithmetic average of the Daily VWAP over the Averaging Period. The “Averaging Period” is the period of 15 consecutive scheduled trading days beginning on June 5, 2014 and ending on June 25, 2014. For the avoidance of doubt, if up to three scheduled trading days during the period beginning on June 5, 2014 are not trading days, ATK will extend the Expiration Date by a number of scheduled trading days that equals the number of scheduled trading days that were not trading days. The “Daily VWAP” for any trading day means the per share volume-weighted average price of ATK’s common stock on the New York Stock Exchange, as displayed under the heading “Bloomberg VWAP” on Bloomberg page “ATK.N AQR” (or its equivalent successor if such page is not available), in respect of the period from the scheduled open of trading until the scheduled close of trading of the primary trading session of the New York Stock Exchange on such trading day (or if such volume-weighted average price is unavailable, the market value of one share of ATK’s common stock on such trading day determined, using a volume-weighted average method, by a nationally recognized independent investment banking firm retained for this purpose by ATK). The Daily VWAP will be determined without regard to pre-market hours or after-hours trading or any other trading outside of the regular trading session trading hours.

ATK will determine the Purchase Price promptly after the close of trading on the New York Stock Exchange on June 25, 2014, unless the Tender Offer has been extended or earlier terminated by ATK. ATK will announce the Purchase Price no later than 4:30 p.m., New York City time, on that day. The Purchase Price will also be available by that time at http://www.gbsc-usa.com/ATK and from the information agent for the Tender Offer. Prior to the determination of the Purchase Price, an indicative purchase price will be available at that same web address and from the information agent for the Tender Offer.

ATK intends to fund the repurchase of the Notes using cash on hand, borrowings from its existing revolving credit facility and the net proceeds of a new incremental term loan. The timing, terms and size of the proposed new incremental term loan are subject to market and other conditions, and ATK cannot provide any assurance that the proposed new loan will be consummated at any specific time, or at all. The Tender Offer is conditioned upon the receipt of financing proceeds of new debt in an aggregate principal amount of at least $100 million.

Subject to applicable law, ATK may, in its sole discretion, waive conditions applicable to the Tender Offer or extend, terminate or otherwise amend the Tender Offer.

None of ATK, its management or board of directors, the dealer manager, the depositary or the information agent makes any recommendation to any holder of Notes as to whether to tender any Notes. None of ATK, its management or board of directors, the dealer managers, the depositary or the information agent has authorized any person to give any information or to make any representation in connection with the Tender Offer other than the information and representations contained in the Offer to Purchase or in the Letter of Transmittal.
