Exhibit 99 CDI Corp. Provides Updated Revenue Outlook for 2004 Third Quarter PHILADELPHIA, Sept. 9 /PRNewswire-FirstCall/ -- CDI Corp. (NYSE: CDI) today announced that it expects third quarter revenues to be flat compared to the second quarter. The Company expects to achieve essentially flat revenues for the third quarter, which is below the previously stated management guidance of "anticipated sequential revenue growth". "While we remain encouraged about our long-term sales pipeline momentum in our engineering and staffing sectors, we have been affected by the slower than anticipated ramp-up of new account wins in our Business Solutions segment," said President and Chief Executive Officer Roger H. Ballou. "In addition, revenue in the Todays Staffing segment has been softer than expected and the Company has experienced losses in billable hours due to business interruption in several offices caused by the two recent hurricanes." "Our business fundamentals are strong and we anticipate achieving sequential revenue growth in the fourth quarter as we experience expected improvements in permanent placement and in new account win ramp-up velocity. We have a very strong pipeline of new wins, which will support our growth objectives. Additionally, the business model we implemented provides healthy earnings leverage on this growth."
