“This was a good, solid quarter, which reflects the results of focused efforts across many fronts: Controlling costs, reducing the backlog in new merchant locations, and renewed stock buyback,” said Bond R. Isaacson, Concord co-chief executive officer. “We had our best quarter ever in new quick service restaurant locations, which grew a net 2,700 restaurants and represented approximately 21% of merchant location growth. Network Services revenue growth improved to its highest level since third quarter 2002. Year over year growth in cost of operations, exclusive of interchange, was kept to its lowest level since first quarter 2002, and selling, general and administrative costs declined as a percentage of revenue for the third quarter in a row. We believe we are entering the fourth quarter with good momentum.”

Year to date 2003 revenue was up 18% over 2002 on transaction growth of 18%, while diluted earnings per share was up 30%. Year to date results include merger and acquisition expense of $17.4 million in 2003 and acquisition, restructuring and write-off charges and litigation settlement charges totaling $86.3 million in 2002. The company currently expects merger-related expenses in connection with the proposed merger with First Data Corporation to be between $20 million and $23 million for the full year 2003, exclusive of investment banking fees payable upon completion of the deal.

Stock Repurchase

During the third quarter 2003 a total of 21.8 million shares at an aggregate cost of $306.3 million were purchased and retired. As of September 30, 2003, a total of 48.6 million shares at an aggregate cost of $699.9 million were purchased and retired since the repurchase plan was initiated in the third quarter 2002.

Market conditions and anticipation of stock repurchase activity prompted the company to liquidate certain third-party securities held for investment in the third quarter, which resulted in a gain on sale of securities of $7.6 million. The securities gain is included in other income.
