CACI Reports Record Second Quarter Results

Revenue Up 7.7 Percent to $419.5 million
Net Income Up 16.4 Percent to $22.3 million

          ARLINGTON, Va., Jan. 25 /PRNewswire-FirstCall/ -- CACI International Inc (NYSE: CAI), a leading information technology and network solutions provider to the federal government, announced today record results for its second fiscal quarter and first six months ending December 31, 2005.

          Second Quarter Results

          The results described in this release include the adoption of Financial Accounting Standards Board Statement No. 123R, “Share Based Payment” (FAS 123R) and the resulting non-cash charges.  The second quarter and first six months of Fiscal Year 2005 (FY05) have been restated as if FAS 123R was in effect as of July 1, 2004, the beginning of FY05.

          For the second quarter of fiscal year 2006 (FY06) the Company reported revenue of $419.5 million, up $29.8 million, or 7.7 percent, over FY05 second quarter revenue of $389.7 million. Organic growth in the quarter was 6.7 percent.  Operating income during the quarter was $39.2 million, 13.1 percent higher than the $34.7 million reported in the year earlier quarter.  The Company’s operating margin in the quarter was 9.4 percent compared with 8.9 percent in the year earlier quarter.  Net income for the second quarter was $22.3 million, or $0.72 per diluted share, 16.4 percent higher than net income of $19.1 million, or $0.63 per diluted share, for the second quarter of FY05.

          Had the Company not been required to adopt FAS 123R, operating income and net income would have been as follows:

	(unaudited) Quarter ended
(Amounts in thousands, except per share amounts)		12/31/2005			12/31/2004		% Growth
Income from operations, as reported	$	39,227		$	34,676
Stock option expense		1,620			2,232
Income from operations before stock option expense	$	40,847		$	36,908		10.7	%
Operating margin before stock  option expense		9.7	%		9.5	%
Net income, as reported	$	22,270		$	19,131
Stock option expense, net of tax		1,018			1,384
Net income before stock option expense	$	23,288		$	20,515		13.5	%
Net profit margin before stock  option expense		5.6	%		5.3	%
Diluted earnings per share before stock option expense	$	0.75		$	0.67

          As most of the Company’s industry peers adopted FAS 123R effective January 1st, the information presented above provides a better comparison to results of its competitors from a margin perspective.

          Second Quarter Highlights:

*	Increased Intelligence Community revenue by 26 percent during the quarter, which now represents 28 percent of CACI’s base of business
*	Closed the acquisition of National Security Research, Inc., a provider  of strategic policy analysis to the highest levels of the federal government
*	Signed a definitive agreement to acquire Information Systems Support, Inc. (ISS), a provider of information technology solutions primarily to the U.S. Government.  ISS’s revenue for calendar year ending December 31, 2005 is projected to be approximately $200 million
*	Reported a cash balance of $137.2 million at December 31, 2005.

          Other Operating Information

          The Company also reported that contract awards in the quarter totaled approximately $208 million.  For the first six months of FY06, contract awards totaled approximately $1,005 million compared with contract awards of $812 million reported for the first six months of FY05.

          Contract funding orders in the quarter were $294 million.  For the first six months of FY06, contract funding orders were $772 million compared with $903 million in the year earlier period.  The lower amount during FY06 is due to many of the Company’s federal government clients operating under a continuing resolution throughout the second fiscal quarter and, as a result, issuing shorter term contract funding orders pending approval of their respective appropriations for FY06.

          CEO’s Commentary

          Commenting on the results, Dr. J. P. London, CACI’s Chairman, President and Chief Executive Officer, said, “CACI delivered record results in the second quarter and the first half of our fiscal year. With the completion of the government’s FY06 appropriations, late in calendar 2005, we are now anticipating a more favorable market environment for the remainder of the government’s fiscal year, through September 30, 2006.

          “In the quarter CACI continued to meet the mission critical needs of its clients particularly in the company’s intelligence sector business which grew 26 percent, and now constitutes 28 percent of CACI’s revenue base.  This growth trend continues in the current quarter with the recent award we received for the Engineering, Technical and Operations Support Services (ETOSS) contract, a major program for intelligence services for the U.S. Army. The selection of CACI assures the Army of proven expertise and uninterrupted support for systems and solutions vital to the Army’s role in the global war on terrorism. Additionally, the pending acquisition of ISS will be an important driver for growth in our intelligence sector support.  Mergers and acquisitions (M&A) is a proven core competency of CACI demonstrated over the past 15 years. As the leading strategic consolidator in our market space, we will continue to pursue transactions that add to our capabilities and accelerate our growth going forward.”

          Dr. London continued, “Our FY06 will be a record year for CACI.  Our first half volume of contract awards, at $1 billion, was up 24 percent over the first half of FY05, and is another record performance for us.  Our merger and acquisition transactions year-to-date will generate over $220 million in acquired annual revenue, which includes the pending close of ISS. Another positive indicator going forward is the robust pipeline of qualified opportunities we are pursuing that continues to exceed $10 billion.  With this pace of business in our market niche, we anticipate exiting FY06 at a revenue run rate of greater than $2 billion annually.  We believe that the federal government services and IT market will remain strong for years to come. Overall, our close alignment with national priorities, and our strong legacy offerings, especially in defense, intelligence, and homeland security firmly positions us to grow and meet our long-term objectives in the years ahead.”

          Six Months FY06 Results

          For the first six months of FY06, revenue increased 8.3 percent to $842.6 million versus $778.3 million of revenue for FY05.  Operating income for the first six months was $72.7 million, 7.0 percent higher than the $68.0 million reported a year earlier. The Company’s operating margin was 8.6 percent for the first six months of FY06 compared with 8.7 percent for the first six months of FY05.  Net income for the first six months was $41.4 million, or $1.34 per diluted share, 10.5 percent higher than net income of $37.5 million, or $1.23 per diluted share, for the first half of FY05.  Operating cash flow for the first six months was $47.1 million compared with $21.1 million in the first six months of FY05.

          Again, had we not been required to record stock option expense under FAS 123R, operating income and net income for the first six months would have been as follows:

	(unaudited) Six months ended
(Amounts in thousands, except per share amounts)	12/31/2005			12/31/2004			Growth %
Income from operations, as reported	$	72,715		$	67,952
Stock option expense		7,401			4,545
Income from operations before stock option expense	$	80,116		$	72,497			10.5	%
Operating margin before stock option expense		9.5	%		9.3	%
Net income, as reported	$	41,393		$	37,471
Stock option expense, net of tax		4,718			2,806
Net income before stock option expense	$	46,111		$	40,277			14.5	%
Net profit margin before stock option expense		5.5	%		5.2	%
Diluted earnings per share before stock option expense	$	1.49		$	1.33

          Acquisition of Information Systems Support, Inc.

          The Company anticipates that the acquisition of ISS will be effective February 1, 2006.  The transaction will be funded through a combination of cash and borrowings under CACI’s existing revolving credit facility.

          CACI Guidance

          During the quarter, the abnormal delay and the unpredictability of when the FY06 DoD appropriations would be signed into law resulted in a constrained spending environment and uncertainty on the part of the Company’s defense customers concerning the full-funding of their programs for FY06.  These factors have resulted in lower contract funding orders in the quarter, delays in forecasted contract awards, and the slower initiation of new work during the government’s fiscal year.  As such, the Company’s guidance in the second half of its fiscal year reflects lower revenue and income from on-going business.  The guidance further reflects a higher percentage of the Company’s revenue in the second half now expected to be coming from subcontractors and other material costs, which yields lower margins.  The guidance update also includes the anticipated acquisition of ISS.  Projected revenue for the remaining quarters and all of FY06, and projected earnings per share shown with and without stock option expense, are as follows:

(In millions except for earnings per share)	3rd Quarter	4th Quarter	Total Year
Revenue	$465 - $475	$502 - $517	$1,810 - $1,835
Diluted earnings per share, exclusive of effect of stock option expense	$0.73 - $0.76	$0.75 - $0.82	$2.97 - $3.07
Stock option expense	$(0.04)	$(0.04)	$(0.24)
Diluted earnings per share, inclusive of effect of stock option expense	$0.69 - $0.72	$0.71 - $0.78	$2.73 - $2.83
Diluted weighted average shares	31.0	31.1	31.0

          The total stock compensation expense, which includes both the expense of stock options as shown above and the expense of restricted stock units granted by the Company, is a non-cash expense that has no effect on the Company’s total cash flow.

          This guidance represents our views as of January 25, 2006.  Investors are reminded that actual results may differ from these estimates for the reasons described below and in our filings with the Securities and Exchange Commission.

          Conference Call Information

          The company has scheduled a conference call for 8:30 AM Eastern time Thursday, January 26th, during which management will be making a brief presentation focusing on second quarter results, operating trends and its expectations.
