          CEO’s Commentary
          Commenting on the results, Dr. J.P. (Jack) London, CACI’s Chairman, President, and Chief Executive Officer, said, “CACI delivered the best year- end and fourth quarter profits and revenue in our history. We set new growth records in every quarter of the fiscal year. Our CACI teams turned in exceptional contributions across all our operations both domestic and international. Our organic growth rate of 16 percent for the year exceeded the high end of our 12 to 15 percent goal.

          We have added new, key staff to our senior management team over the last 12 months, including the recent addition of Paul Cofoni as President of our U.S. Operations. Paul brings significant senior-level Tier 1 leadership that will reinforce our Tier 1 competitive position and facilitate our goal to deliver $3 billion in annual revenue by our fiscal year 2009.”

          Dr. London continued, “CACI is a strong growth company in a dynamic market. Our capabilities are aligned with national priorities in defense, intelligence, homeland security, and the transformation of the way the federal government does business. Our strategy is focused on helping government clients complete their most important missions, so we grow in areas of the government’s most critical needs. Thanks to a very successful core business strategy and our exceptional CACI team, we have met our growth targets again and produced another outstanding fiscal performance.”

          CACI Reiterates Guidance and Adopts FAS 123R
          The Company reiterates its guidance for its first quarter and full year FY06 as originally issued on June 23, 2005.  This guidance excludes the revenue or earnings from future acquisitions that may be completed prior to the end of FY06.

3

          Projected revenue and earnings for FY06 includes the adoption of FAS 123R and is shown with and without the effect of stock option expensing, as follows:

(In millions except for earnings per share)	1st Quarter	Total Year
Revenue	$420 - $430	$1,775 - $1,850
Pro forma diluted earnings per share, exclusive of effect of stock option expense	$0.71 - $0.74	$3.10 - $3.25
Stock option expense	$(0.11) - $(0.12)	$(0.26) - $(0.27)
Diluted earnings per share, inclusive of effect of stock option expense	$0.60 - $0.62	$2.84 - $2.98
Diluted weighted average shares	30.9	31.0

          The greater effect of expensing options in the first quarter relative to all of FY06 is due to immediate expense recognition, as required by accounting principles generally accepted in the U.S., of 100 percent of the entire estimated fair value of certain option grants.  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 cash flow.  Investors are cautioned that street consensus estimates may or may not reflect the effects of FAS 123R.

          This guidance represents our views as of August 17, 2005.  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, August 18th, during which management will be making a brief presentation focusing on fourth quarter results, operating trends and its expectations. A question-and-answer session will follow to allow further discussion of the results and the company’s future expectations.
