CACI Reports Record Second Quarter and First Half Results

Net Income up 44% for the Quarter to $20.5 Million

Operating Income up 59% for the Quarter to $36.9 Million

Revenue up 48% for the Quarter to $389.7 Million

Diluted Earnings Per Share up 40% to $0.67

          ARLINGTON, Va., Jan. 24 /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 half ending December 31, 2004.  Net income for the second quarter of Fiscal Year 2005 (FY05) increased 44 percent, while revenue was up 48 percent compared to the second quarter of Fiscal Year 2004 (FY04). For the first six months of FY05, net income was up 48 percent, while revenue was up 56 percent versus a year ago.

          The increase in earnings and revenue in the quarter resulted from continuing growth in the systems integration, engineering services, and network services offerings of the company’s operations.  Internal revenue growth for the company in the quarter was 14 percent, and 18 percent for the trailing twelve months.  This growth is a result of CACI’s strategic focus 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. 

          Second Quarter Results Reflect Higher Operating Margin and Expansion of Current Work

          Net income for the second quarter of FY05 was $20.5 million, or $0.67 per diluted share, an increase of 44 percent over net income of $14.3 million, or $0.48 per diluted share, reported in the second quarter of FY04.  Revenue for the quarter was $389.7 million, an increase of 48 percent over second quarter FY04 revenue of $263.4 million.  Operating income in the quarter was $36.9 million, an increase of 59 percent over second quarter FY04 operating income of $23.2 million.  For the second quarter, the operating margin increased to 9.5 percent from 8.8 percent a year earlier.

          The operating margin increase was driven primarily by a favorable mix of business, operational efficiencies and acquisitions.  The growth of the company’s operations was driven primarily by the expansion of work on current contracts as a result of the continuing need of federal government customers for support in the areas of information technology and solutions.  Domestic operations continued to reflect the trend of increased demand for mission- critical support for intelligence community customers and for systems integration, engineering and logistics, and network services for the Department of Defense (DoD). 

          Second Quarter Highlights
          The following highlights occurred during the second fiscal quarter:

*	Revenue from DoD customers increased 66 percent compared to the second  fiscal quarter of FY04 as a result of the acquisition of the AMS  Defense and Intelligence Group and the continuing demand from customers  such as strategic and tactical organizations in the military  intelligence community, the Army’s Communications-Electronics Command,  the Defense Information Systems Agency, the U.S. Navy and other  organizations within the DoD.
*	Awards in the quarter totaled approximately $235 million, and $812 million over the first six months of FY05.
*	Operating cash flow for the quarter was $9.6 million, and $30.6 million  over the first six months of FY05.
*	Total debt was reduced by $25.9 million during the quarter, and by $44  million during the first half of FY05.

          Commentary
          Commenting on the results, Dr. J.P. London, CACI’s Chairman, President, and Chief Executive Officer, said, “CACI’s solid results in the second fiscal quarter continue to reflect our strategic focus on the key aspects of national security and intelligence, homeland security and law enforcement, and the transformation of government.  It is highly evident that our progress is being driven by deepening relationships with long-standing customers, by effectively integrating acquired talent and capabilities, and by winning new customers. This has produced our higher operating profit margin, which we believe we can continue to enhance going forward.  It has also resulted in another quarter of strong cash flow, allowing us to further reduce our debt.  We were able to accomplish all this by continuing to deliver value-added support and meeting the expanding, critical needs of our diverse government customer base.”

          Dr. London continued, “We believe we are well-positioned for the balance of our fiscal year.  We expect the operational pace we’ve experienced so far in FY05 to continue.  As we recently announced, two senior operational executives, Randy Fuerst and Keith Kellogg, have joined CACI to manage areas key to our future growth.  Randy Fuerst leads our network services area where we are providing mission-critical support and solutions to customers throughout the federal government.  Keith Kellogg will lead our mission- support area where we are providing specialized intelligence and information technology solutions to the DoD.  We believe that all of CACI will continue to grow through the support we provide to our government customers not only within the United States but also in supporting DoD international operations and the global challenges they face.  We expect to accomplish this through the ongoing implementation of our growth strategy of maintaining our base of business, growing by winning new work in key areas, and making accretive acquisitions.  Overall, we believe we are well positioned to continue to deliver and enhance shareholder value in the second half of our FY05.” 

          First Six Months FY05 Results Reflect Operational Efficiencies and Ability to Successfully Integrate Large Acquisitions

          Net income for the first six months of FY05 was $40.3 million, or $1.33 per diluted share, an increase of 48 percent over net income of $27.2 million, or $0.91 per diluted share, reported in the first half of FY04.  Revenue for the first six months was $778.3 million, an increase of 56 percent over first half FY04 revenue of $499.1 million.  Operating income in the first six months of FY05 was $72.5 million, an increase of 66 percent over first half FY04 operating income of $43.7 million.  For the first half of FY05, the operating margin increased to 9.3 percent from 8.8 percent a year earlier.

          Revenue growth was driven by increased demand from federal government customers and acquisitions.  Net cash provided by operations for the first six months of FY05 was $30.6 million versus net cash used in operations of $12.9 million reported a year earlier. 

          Company Increases Guidance
          The company also increased its guidance for its full year FY05, and issued initial guidance for its third and fourth fiscal quarters.  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)	Q3 FY05		Change		Q4 FY05		Change		Total FY05		Change
Revenue		$395-$405		37%-40%		$402-$417		12%-16%		$1,575-$1,600		37%-40%
Net income		$20.5-$21.4		30%-36%		$21.1-$22.3		2%-8%		$81.8-$84.0		28%-32%
Diluted earnings per share		$0.67-$0.70		26%-32%		$0.68-$0.72		(1%)-4%		$2.68-$2.75		26%-29%
Diluted weighted average shares		30.7				30.9				30.5

          Our fourth quarter FY04 net income included higher than expected margins on one contract with fixed unit pricing, and higher than anticipated award fees which provided us with significant one-time benefits.  These benefits are not expected to occur again in the fourth quarter of FY05.

          Investors are reminded that actual results may differ from these estimates for the reasons described below.
