CACI Reports Another Record Third Quarter
and Nine Months Results and Raises Guidance

Diluted earnings per share up 34% to $0.71

Net income up 37% for the quarter to $21.6 million

Operating income up 52% for the quarter to $38.3 million

Revenue up 44% for the quarter to $414.9 million

Operating cash flow of $45.3 million in the quarter

          ARLINGTON, Va., April 20 /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 third fiscal quarter and nine months ending March 31, 2005.  Net income for the third quarter of fiscal year 2005 (FY05) increased 37 percent, while revenue was up 44 percent compared to the third quarter of fiscal year 2004 (FY04).  For the first nine months of FY05, net income was up 44 percent.  Revenue was up 52 percent versus a year ago.  Fundings from all contract sources were up 29 percent versus the prior year.

          The increase in earnings, revenue, and fundings in the quarter resulted from continuing growth across CACI’s diversified customer base for the systems integration, engineering services, and network services offerings of the company.  Organic revenue growth for the company in the quarter was 14.7 percent.  This growth is a result of CACI’s strategic focus and concentration on national security and intelligence, the global war against terrorism, and the reshaping of the way government agencies communicate, use and disseminate information, and deliver services to the citizens.  These areas continue to be of high national priority and are expected to receive strong funding support going forward.

          Third Quarter Results Reflect Increased Operating Margin and Strong Cash Flow
          Net income for the third quarter of FY05 was $21.6 million, or $0.71 per diluted share, an increase of 37 percent over net income of $15.8 million, or $0.53 per diluted share, reported in the third quarter of FY04.  Revenue for the quarter was $414.9 million, an increase of 44 percent over third quarter FY04 revenue of $288.4 million.  Operating income in the quarter was $38.3 million, an increase of 52 percent over third quarter FY04 operating income of $25.2 million.  For the third quarter, the operating margin increased to 9.2 percent from 8.7 percent a year earlier.  Net cash provided by operations in the quarter was $45.3 million, up 76 percent versus $25.8 million in the third fiscal quarter of FY04.

          The growth of the company’s operations was driven by both ongoing and new tasking to support the mission-critical needs of CACI’s Department of Defense (DoD) and intelligence community clients.  The operating margin increase was primarily from operational efficiencies including the highly successful integration of the Defense and Intelligence Group (D&IG) purchased from American Management Systems, Inc. This improvement more than offset the costs of Sarbanes-Oxley compliance, Restricted Stock Units, and Iraq-related costs.

          Third Quarter Highlights

          Highlights for CACI’s third fiscal quarter included:

*	Organic revenue growth for the company was 14.7 percent.
*	DoD revenue increased 54 percent compared to the third fiscal quarter of FY04 primarily as a result of the acquisition of the D&IG and the continuing demand from customers such as the military intelligence community, the Army’s Communications-Electronics Command, the Defense Information Systems Agency, and the U.S. Navy.
*	Fundings from all contract sources in the quarter were $465 million, an increase of 17.5 percent over the prior year. (Fundings from all contract sources for the first nine months increased significantly to $1.368 billion, up 29 percent from last year.)
*	A total of $1.6 billion in new proposals was submitted during the quarter, reflecting a dramatic increase in bid activity, and resulting in a total of $1.9 billion in proposals currently under evaluation for award.  Contract awards in the quarter were approximately $142 million, bringing the total contract awards for the first nine months of FY05 to approximately $954 million.
*	Total debt was reduced by $20.8 million during the quarter.
*	Operating cash flow increased to $45.3 million compared to $25.8 million a year ago.
*	Operating margin improved to 9.2 percent in the quarter compared to 8.7 percent last year.
*	Days sales outstanding improved to 76 days compared to 84 days a year ago.
*	A universal shelf registration statement was filed to enable the company to offer and sell up to $400 million of common stock, preferred stock, or debt securities from time to time in one or more public offerings.

          CEO’s Commentary
          Commenting on the results, Dr. J.P. London, CACI’s Chairman, President, and Chief Executive Officer, said, “CACI had a terrific third quarter, with strong operating metrics and solid revenue growth.  Our operating profits rose significantly and we increased our operating margin.  We also experienced exceptionally strong operating cash flow during the quarter.  Our organic growth was 14.7 percent, at the high end of our 12 to 15 percent operating goal.  With these results, we are building another record year for CACI.”

          Dr. London continued, “The volume of Requests for Proposals (RFPs) from CACI’s customers and prospects has increased significantly from three months ago.  When compared with the first half of our fiscal year, we are seeing a dramatic increase in the number of opportunities to which we are responding. CACI currently has approximately $1.9 billion in proposals under evaluation for award. We also anticipate that we will submit another $4.0 billion in proposals by the end of September 2005.  Approximately $3 billion of this $5.9 billion total is expected to be awarded by the end of the government’s fiscal year ending on September 30, 2005.

          “We are also actively seeking strategic acquisitions that will further expand our customer base and enhance our capabilities.  We are accelerating our recruiting activities to expand our employee population.  We’ve experienced a very high operational pace throughout this fiscal year as a result of the increasing reliance by the federal government on contractor support from the private sector. We believe that the combination of all these positive factors should position us for a strong fiscal year 2006 (FY06: July 1, 2005) and the continued enhancement of shareholder value.  Entering next year, our operating goal remains intact:  to grow CACI in excess of 20 percent -- 12 to 15 percent organically and five to eight percent through acquisitions.”

          First Nine Months FY05 Results Put CACI on Track for Record Year
          Net income for the first nine months of FY05 was $61.9 million, or $2.03 per diluted share, an increase of 44 percent over net income of $43.0 million, or $1.44 per diluted share, reported in the first nine months of FY04. Revenue for the first nine months was $1.193 billion, an increase of 52 percent over the first nine months FY04 revenue of $787.5 million.  Operating income in the first nine months of FY05 was $110.8 million, an increase of 61 percent over the first nine months FY04 operating income of $69.0 million. For the first nine months of FY05, the operating margin increased to 9.3 percent from 8.8 percent a year earlier.  Fundings from all contract sources for the first nine months increased significantly to $1.368 billion, up 29 percent from last year.

          Revenue growth was driven by growth in support to DoD customers and our successful acquisitions.  Net cash provided by operations for the first nine months of FY05 was $75.9 million, significantly exceeding the $12.9 million for the same period of FY04, and almost equal to cash generated for all of FY04.

          CACI Increases Guidance
          The company increased its guidance for its fourth quarter and for its full year FY05.  CACI’s organic revenue growth for the full year is projected to be between 15 and 16 percent. This guidance excludes any revenue or income from additional acquisitions that might be closed prior to the end of FY05.  The table below summarizes the guidance ranges for each of those periods and shows the change over the same periods in FY04: 

(In millions except for earnings per share)	Q4 FY05		Change		Total FY05		Change
Revenue		$415-$425		16%-19%		$1,608-$1,618		40%-41%
