NCI Reports First Quarter 2011 Financial and Operating Results

Highlights:

• Revenue of $150 million, up 31%, all organic¹;

• Diluted EPS of $0.41;

• Company updates Fiscal Year 2011 revenue and earnings guidance.

RESTON, Va., May 4, 2011 — NCI, Inc. (NASDAQ:NCIT), a leading provider of information technology (IT), engineering, logistics, and professional services and solutions to U.S. federal government agencies, today announced financial and operating results for the first quarter ended March 31, 2011.

First quarter revenue was at the midpoint of management’s guidance, and diluted earnings per share, excluding acquisition-related costs, were at the low end of guidance.

First Quarter Fiscal Year 2011 Results:

For the first quarter of 2011, NCI reported revenue of $150.2 million, all organic, an increase of 31% over first quarter 2010 revenues of $115.0 million. The year-over-year increase in revenue was attributable primarily to growth in the Army Program Executive Office (PEO) Soldier and Base Realignment and Closure (BRAC) contracts, as well as network management and analysis services under new and existing contracts.

¹ Organic revenue growth, as presented, measures revenue growth adjusted for the impact of acquisitions. NCI believes that this non-GAAP financial measure provides useful information because it allows management and investors to better assess the underlying growth rate of the company’s existing business. This non-GAAP financial measure should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP.

Operating income for the first quarter of 2011 increased by 10.1% over first quarter of 2010. Operating income for the first quarter of 2011 was $9.7 million, or 6.5% of revenue, compared with $8.8 million, or 7.7% of revenue, for the three months ended March 31, 2010. The year-over-year decrease in operating margin was attributed to increases in materials and subcontractor labor costs, which typically carry lower margins than the company’s direct labor costs. Operating margin was also impacted by $0.2 million of costs incurred related to the acquisition of AdvanceMed Corporation, which was completed on April 1, 2011.

Materials-related revenue associated with the BRAC and U.S. Air Force’s Network Centric Solutions (NETCENTS) contracts, contributed little to no operating margin. Excluding this BRAC and NETCENTS revenue and related costs, operating margin was 7.2% and 7.9% for the first quarters of 2011 and 2010, respectively. Excluding the aforementioned acquisition costs as well, operating margin was 7.4% for the first quarter of 2011.

The effective tax rate for the first quarter of 2011 was 40.1% compared with 36.9% for the first quarter of 2010. The prior year effective tax rate was lower due to a one-time credit related to a corporate tax reorganization completed in 2010.

Net income for the first quarter of 2011 was $5.7 million, compared with $5.5 million for the same period in 2010. Diluted earnings per share were $0.41 per share for the first quarter of 2011 compared with $0.39 per share for the first quarter of 2010.

NCI reported total backlog at March 31, 2011 of $1.2 billion, of which $227 million was funded. This compares with total backlog of $1.3 billion at December 31, 2010, of which $302 million was funded.

Cash flow used in operating activities for the first quarter of 2011 was $7.3 million. Capital expenditures for the first quarter of 2011 were $0.6 million. Days sales outstanding, or DSO, for the quarter was 73 days, up from 71 days for the quarter ended December 31, 2010.

First Quarter Fiscal Year 2011 and Recent Operational Highlights:

• First quarter net bookings totaled $77 million, equating to a book-to-bill ratio of 0.5:1

• Among new business awards and additional tasking in the first quarter:

2

• Won a prime position on the Department of Justice’s Information Technology Support Services-4 (ITSS-4) contract. The contract has a $1.1 billion ceiling and a seven-year period of performance to provide IT support services, including cyber security;

• A prime position on the U.S. Army Total Engineering and Integration Services, TEIS III, contract. The contract has a $892 million ceiling with a five year period of performance to provide systems engineering and IT support;

• A $26.5 million, four-and-a-half-year task order to continue and expand IT and program management support for the Air National Guard; and

• An $11 million, five-year task order under the GSA Alliant contract to continue NCI’s support of the 81^st Medical Group’s Air Education and Training Command.

• Completed the acquisition of AdvanceMed on April 1^st, solidly placing NCI in the program integrity services marketplace.

• Named Philip O. Nolan to NCI’s Board of Directors.

NCI’s President, Terry Glasgow, stated, “With one quarter behind us, 2011 is shaping-up to be a year of both promise and challenge. We enter the second quarter with more than $500 million of bids submitted and awaiting award. In addition, we have submitted four prime GWAC and ID/IQ bids awaiting award with a combined ceiling value of more than $50 billion. Additionally, our acquisition of AdvanceMed provides us substantial momentum to deliver strong operational results in 2011. We believe our future holds tremendous promise as our team executes in a challenging federal procurement environment.”

Management’s Outlook:

Based on the company’s current contract backlog and management’s estimate as to future tasking and contract awards, NCI is issuing guidance for its fiscal year 2011 second-quarter and updating guidance for its full 2011 fiscal year. The table below represents management’s current expectations about future financial performance, based on information available at this time:

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; the overall U.S. Defense budget declined from time to time during the late 1980s and the early 1990s. While spending authorizations for Defense- and Intelligence-related programs by the Federal Government have increased in recent years, future levels of expenditures and authorizations for those programs may decrease, remain constant, or shift to programs in areas where we do not currently provide services; Federal Governmental shutdowns (such as that which occurred during the Federal Government’s 1996 fiscal year) and other potential delays in the Government appropriations process; 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); Federal Government agencies are more frequently awarding contracts on a technically acceptable/lowest cost basis in order to reduce expenditures 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, such as our AdvanceMed acquisition or others; 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 Indefinite Delivery/Indefinite Quantity (IDIQ) contracts and/or schedule contracts with the General Services Administration; and (vi) 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.

The forward-looking statements included in this news release are only made as of the date of this news release and NCI undertakes no obligation to publicly update any of the forward-looking statements made herein, whether as a result of new information, subsequent events or circumstances, changes in expectations or otherwise.
