Exhibit 99.1 April 18, 2005 Cass Information Systems Reports 50% Increase in 1st Quarter 2005 Net Income Earns All-Time High of 74 Cents Per Share, 48% Increase Over 2004 ST. LOUIS - Cass Information Systems, Inc. (NASDAQ: CASS), the nation's leading provider of freight, utility and telecom invoice payment, auditing and information services, set a new all-time high for per-share earnings in the first quarter of 2005. The company reported first quarter earnings of 74 cents per fully diluted share for the period, a 48% increase over the 50 cents per fully diluted share it earned in the first quarter of 2004. Total net income was $2,767,000, a 50% increase over the $1,847,000 reported in the comparable period last year. The first quarter results were driven by a combination of higher processing volumes, fee revenues, software sales and investment income. "While our approach to business and investment decisions is long-term oriented, it is gratifying when events converge in a given period to produce such an encouraging result for our shareholders," said Lawrence A. Collett, chief executive officer and chairman of the board. "As always, we remain optimistic in our outlook and confident in our abilities to grow the company in the year ahead." A 31% increase in freight processing volume and a 9% increase in utility invoice processing volume, combined with 16% and 10% increases in dollars processed respectively, fueled a $994,000 or 13% rise in processing fees. A growing customer base, aided by the August 2004 acquisition of PROFITLAB, Inc., contributed to the processing growth. The company's Government e-Management Solutions, Inc. subsidiary also posted sharply stronger results, generating a $501,000 increase in software revenues, a 42% improvement over the first quarter of 2004. 5 Net investment income advanced $953,000, a 15% increase over the first quarter of 2004. A gradual rise in prevailing interest rates, coupled with a higher base of earning assets, were responsible for the outcome. Finally, CASS recorded a gain of $547,000 in the sale of securities during the period, compared to the $441,000 gain it posted last year. Meanwhile, operating expenses increased 8% ($1,060,000) year-to-year due to the PROFITLAB acquisition and growth in processing activity.
