Forward-Looking Statement: Statements and assumptions made in this press release, which do not address historical facts, constitute “forward-looking” statements that NCI believes to be within the definition in the Private Securities Litigation Reform Act of 1995 and involve risks and uncertainties, many of which are outside of our control. Words such as “may,” “will,” “intends,” “should,” “expects,” “plans,” “projects,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” “continue,” or “opportunity,” or the negative of these terms or words of similar import are intended to identify forward-looking statements.

Such statements are subject to factors that could cause actual results to differ materially from anticipated results. The factors that could cause actual results to differ materially from those anticipated include, but are not limited to, the following: our dependence on our contracts with Federal Government agencies, particularly within the U.S. Department of Defense, for substantially all of our revenue; continued funding of U.S. Government, based on a change in spending priorities, or in the event of a priority need for funds, such as homeland security, the war on terrorism or rebuilding Iraq; risk of contract performance or termination; failure to achieve contract awards in connection with recompetes for present business and/or competition for new business; adverse results of Federal Government audits of our government contracts; Government contract procurement (such as bid protest, small business set asides, etc.) and termination risks; competitive factors such as pricing pressures and competition to hire and retain employees (particularly those with security clearances); failure to successfully identify and integrate future acquired companies or businesses into our operations or to realize any accretive or synergistic effects from such acquisitions or to effectively integrate acquisitions appropriate to the achievement of our strategic plans; adverse results of U.S. Government audits of our Government contracts; economic conditions in the United States, including conditions that result from terrorist activities or war; material changes in laws or regulations applicable to our businesses, particularly legislation affecting (i) government contracts for services, (ii) outsourcing of activities that have been performed by the government, (iii) government contracts containing organizational conflict of interest (OCI) clauses, (iv) delays related to agency specific funding freezes, (v) competition for task orders under Government Wide Acquisition Contracts (GWACs), agency-specific IDIQ contracts and/or schedule contracts with the General Services Administration; and (vi) the Government’s “insourcing” of previously contracted support services and the realignment of funds to other non-defense related programs and (vii) our own ability to achieve the objectives of near-term or long-range business plans, including internal systems failures. These and other risk factors are more fully discussed in the section titled “Risks Factors” in NCI’s Form 10-K filed with the Securities and Exchange Commission (SEC), and from time to time, in other filings with the SEC, such as our Forms 8-K and Forms 10-Q.
