Exhibit 99.4

NCI, Inc.

Unaudited Pro Forma Condensed Consolidated Financial Statements

On June 27, 2007, NCI, Inc. (“the Company”) purchased Karta Technologies, Inc. (“Karta”). The Company paid approximately $67.6 million for Karta. The purchase price includes $64.8 million for Karta, $0.2 million for a non-compete agreement, $1.5 million as a working capital adjustment and approximately $1.1 million in transactions costs. The following unaudited pro forma condensed consolidated balance sheet as of March 31, 2007 and the unaudited pro forma condensed consolidated statements of operations for the quarter ended March 31, 2007 and the fiscal year ended December 31, 2006 give effect to the Company’s purchase of Karta. The acquisition has been accounted for using the purchase method in accordance with Statement of Financial Accounting Standards No. 141, Business Combinations.

The unaudited pro forma condensed consolidated balance sheet presents the financial position of the Company as if the acquisition of Karta occurred on March 31, 2007. The unaudited pro forma condensed consolidated statement of operations for the quarter ended March 31, 2007 has been prepared as if the acquisition occurred on January 1, 2007. The unaudited pro forma condensed consolidated statement of operations for the year ended December 31, 2006 has been prepared as if the acquisition occurred on January 1, 2006.

The unaudited pro forma adjustments are based on management’s preliminary estimates of the value of the tangible and intangible assets and liabilities acquired. As a result, the actual adjustments may differ materially from those presented in these unaudited pro forma statements. A change in the unaudited pro forma adjustments of the purchase price for the acquisition would primarily result in a reallocation affecting the value assigned to tangible and intangible assets. The income statement effect of these changes will depend on the nature and amount of the assets or liabilities adjusted.

The unaudited pro forma condensed consolidated financial statements, which have been prepared in accordance with rules prescribed by Article 11 of Regulation S-X, are provided for informational purposes only and are not necessarily indicative of the past or future results of the operations or financial position of the Company.

This information should be read in conjunction with the previously filed Current Report on Form 8-K, dated June 27, 2007 and filed with the Securities and Exchange Commission, the previously filed historical consolidated financial statements and accompanying notes of the Company contained in its Annual Report on Form 10-K for the fiscal year ended December 31, 2006, and other subsequent filings and in conjunction with the historical financial statements and accompanying notes of Karta included in this report on Form 8-K/A.
