Arlington, VA, August 13, 2003 - CACI International Inc (NYSE: CAI), a leading information technology and network solutions provider to the federal government, announced today record results for its fourth quarter and fiscal year ending June 30, 2003 (FY03). Income from continuing operations in the quarter increased 43 percent while revenue was up 20 percent compared to the fourth quarter of fiscal year 2002 (FY02). For all of FY03, income from continuing operations was up 40 percent while revenue was up 24 percent versus a year ago. The increase in earnings and revenue in the quarter and for the full year resulted from continuing growth in all of the company's service offerings through its domestic operations.

Fourth Quarter Results Reflect Higher Margins and Strong Cash Flow

Net income for the fourth quarter of FY03 was $13.3 million, or $0.45 per diluted share, an increase of 43 percent over net income of $9.3 million, or $0.32 per diluted share, reported in the fourth quarter of FY02. Revenue for the quarter was $228.6 million, an increase of 20 percent over fourth quarter FY02 revenue of $191.0 million. Operating income in the quarter was $21.1 million, an increase of 43 percent over fourth quarter FY02 operating income of $14.7 million.

For the fourth quarter the operating margin increased to 9.2 percent from 7.7 percent a year earlier. The higher operating margin was driven primarily by a favorable contract mix, specifically increased professional services revenue on higher margin time and material and fixed price contracts. The growth in net income was primarily attributable to increased sales to the company's federal customers and improved margin performance. Operating cash flow of $33.9 million was primarily driven by net income and cash collections.

The growth of the company's operations continued to be driven by increased demand for C⁴ISR (command, control, communications, computers, intelligence, surveillance, and reconnaissance) work for intelligence and logistical support for ongoing Department of Defense (DoD) operations and by domestic acquisitions.

Fourth Quarter Highlights

The following highlights occurred during the fourth fiscal quarter:

Revenue from DoD customers increased 19 percent, driven primarily by higher demand from customers such as the Defense Information Systems Agency (DISA), the U.S. Army's Communications-Electronics Command (CECOM), and the defense intelligence community.

Federal civilian agency revenue grew 28 percent primarily from higher volumes of work for customers such as the Department of Justice (DoJ), Department of Veterans Affairs (VA), the Securities and Exchange Commission (SEC), the U.S. Customs Service, and the national intelligence community.

The acquisition of Premier Technology Group, Inc. (PTG), which closed on May 15, 2003, broadened CACI's capabilities in intelligence analysis and security services, information technology, training, program management and logistics for clients in the DoD and the intelligence community.

Full Year FY03 Results Reflect Continued Margin Expansion and Strong Revenue Growth

Income from continuing operations for FY03 was $44.7 million, or $1.52 per diluted share, an increase of 40 percent over income from continuing operations of $31.9 million, or $1.24 per diluted share, reported for FY02. For all of FY03, revenue increased 24 percent, to $843.1 million, compared with $681.9 million reported in FY02. Operating income for FY03 was $70.4 million, up 33 percent over operating income of $53.1 million reported a year earlier.

For the full year, the operating margin improved to 8.4 percent from 7.8 percent a year earlier. The higher operating margin was driven primarily by a favorable contract mix, specifically increased professional services revenue on higher margin time and material and fixed price contracts.

Revenue growth was driven primarily by increased demand from federal government customers. Revenue from DoD customers increased 24 percent, driven primarily by higher demand from customers such as the Defense Information Systems Agency (DISA), the U.S. Army's Communications-Electronics Command (CECOM), and the defense intelligence community. Federal civilian agency revenue grew 31 percent primarily from higher volumes of work for customers such as the Department of Justice (DoJ), Department of Veterans Affairs (VA), the Securities and Exchange Commission (SEC), the U.S. Customs Service, and the national intelligence community.

FY03 Highlights

In addition to record revenue and earnings, major highlights and accomplishments during fiscal year 2003 include:

Operating cash flow of $75.9 million.

Revenue from the federal government increased 26 percent, 16 percent organically. Overall, internal revenue growth for the company for the fiscal year was 15 percent.

Contract awards of up to eight years in length for over $1.1 billion from federal customers.

Backlog at year-end of $2.5 billion, up from $1.9 billion a year earlier.

Acquisition and full integration of four domestic businesses--the Government Services Division of Condor, Acton Burnell, Inc., Applied Technology Solutions of Northern VA, Inc., and Premier Technology Group, Inc.

Common stock listed on the New York Stock Exchange.

Commentary

Commenting on the results, Dr. J.P. London, CACI's Chairman, President, and Chief Executive Officer, said, "Our record year and fourth quarter results are driven by high ongoing demand from those government agencies and spending initiatives that are presently involved with our country's highest national priorities: defense, intelligence, and homeland security. By responding to our customers' needs related to those priorities and delivering to them timely, critical support, we experienced growth in our profitability as well as the overall business. We experienced record cash flow from operations. We received over $1.1 billion in contract awards and maintained our historically high win rate in customer retention. And we gained new customers and broadened our capabilities through our acquisition program. All of this combined to produce solid growth of 24 percent for the year and 15 percent internally, exceeding our stated growth objectives."

Dr. London continued, "We have a well-diversified business base between DoD and federal civilian agencies. We continue to experience strong demand across the federal government market. As we begin our new fiscal year, we are actively hiring additional staff in our domestic operations. Our bid backlog of submitted proposals has increased to over $1 billion, plus we have no additional major contracts being recompeted this fiscal year. And we have recently signed a Letter of Intent for our next potential acquisition. We believe we are well on our way to becoming a $1 billion in annual revenue company in FY04, reaching our goal a year ahead of schedule. We continue to anticipate strong growth across all areas of our core business, including systems integration, engineering services, knowledge management, and managed network services. As we move forward, CACI remains ever vigilant in helping our country secure its future both domestically and abroad. We are extremely pleased with our results and excited about the prospects of achieving another record year of growth and profitability while continuing to enhance shareholder value."

Company Outlook

The company reiterated its guidance for FY04 as originally issued on July 8, 2003. For the full year, there is no change to the range of guidance for revenue, net income and diluted earnings per share. The company's guidance excludes results from any additional acquisitions, including that resulting from the above-mentioned Letter of Intent. The company will update its full year guidance upon successful completion of the acquisition, which is anticipated to close in September. The company continues to target its overall growth at a 20 percent or better compound annual growth rate, through a combination of organic growth ranging between 12 and 15 percent and acquired growth of between five and eight percent. The table below summarizes the guidance ranges for the first quarter and full fiscal year 2004:

(In millions except for earnings per share)	Q1 FY04	Total FY04
Revenue	$233 - $240	$985 - $1,015
Net Income	$12.3 - $12.7	$53.1 - $54.7
Diluted earnings per share	$0.41 - $0.43	$1.77 - $1.82
Diluted weighted average shares	29.7	30.0

Should the company perform in accordance with these estimates, revenue for the first quarter is expected to be up 24 to 28 percent over revenue of $188 million reported in the first quarter of FY03. Net income is anticipated to be up 31 to 35 percent over net income of $9.4 million in the corresponding prior year quarter. Diluted earnings per share are expected to be up 29 to 34 percent over $0.32 reported a year earlier.

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