Forward Looking Statements This communication may contain statements, other than statements of historical fact that constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Words such as “expect,” “intend,” “may,” “could,” “plan,” “project,” “forecast,” “believe,” “estimate,” “outlook,” “anticipate,” “trends,” “goals” and similar expressions generally identify these forward-looking statements. Forward-looking statements include, among other things, statements relating to the Company’s future financial condition, results of operations and/or cash flows, expected benefits of the proposed acquisition, the timing of the proposed acquisition and financing the proposed acquisition. Forward-looking statements are based upon assumptions, expectations, plans and projections that the Company believes to be reasonable when made, but which may change over time. These statements are not guarantees of future performance and inherently involve a wide range of risks and uncertainties that are difficult to predict. Specific risks that could cause actual results to differ materially from those expressed or implied in these forward-looking statements include, but are not limited to: those discussed in this communication, those identified under “Risk Factors” and other important factors disclosed in the Company’s Annual Report on Form 10-K and from time to time in the Company’s other filings with the SEC; the possibility that Orbital ATK stockholders may not approve the proposed acquisition; the possibility that the closing conditions of the proposed acquisition may not be satisfied; the possibility that regulatory approvals required for the proposed acquisition may not be obtained on acceptable terms, on the anticipated schedule, or at all; the possibility that long-term financing for the proposed acquisition may not be available on favorable terms, or at all; the risk that closing of the proposed acquisition may not occur or may be delayed, either as a result of litigation or otherwise; the occurrence of an event that could give rise to termination of the proposed acquisition; the risk that stockholder litigation in connection with the proposed acquisition may affect the timing or occurrence of the proposed acquisition or result in significant costs of defense, indemnification and liability; the possibility that anticipated benefits of the proposed acquisition may not be realized or may take longer to realize than expected; the possibility that costs related to the Company’s integration of Orbital ATK’s operations may be greater than expected and/or that revenues following the proposed acquisition may be lower than expected; the effect of the transaction on the ability of the Company and Orbital ATK to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers, including the U.S. Government; responses from customers and competitors to the proposed acquisition; the possibility that the Company’s business or Orbital ATK’s business may be disrupted due to transaction-related uncertainty; the risk that the proposed acquisition may distract the Company’s management from other important matters; the impact of legislative, regulatory and competitive changes; results from the proposed acquisition different than those anticipated; and the other risks and uncertainties detailed in Orbital ATK’s filings, including its Annual Report on Form 10-K, with the SEC.You are urged to consider the limitations on, and risks associated with, forward-looking statements and not unduly rely on the forward-looking statements including the accuracy thereof. Forward-looking statements are based on information, plans and estimates as of the date they are made and there may be other factors that may cause actual results to differ materially from these forward-looking statements. The Company undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, subsequent events or otherwise, except as required by applicable law. 2
