Cass Information Systems, Inc. Ends 2005
With 36% Per Share Earnings Increase Over 2004

      ST. LOUIS - Cass Information Systems, Inc. (NASDAQ: CASS), the nation's
leading provider of transportation, utility and telecom invoice payment and
information services, reports that it earned $1.94 per fully diluted share for
the year ended Dec. 31, 2005, a 36% increase over the $1.43 per share (adjusted
for a 50% stock dividend issued Sept.15, 2005) earned in 2004. Net income was
$10,946,000 in 2005, a 37% increase over the $8,005,000 earned in 2004.

4th Quarter 2005 Earnings

      Fourth quarter 2005 earnings were 44 cents per fully-diluted share,
identical to the result posted in the fourth quarter of 2004. Net income for the
period was $2,503,000, compared to the $2,485,000 reported during the final
quarter of 2004.

      Quarterly earnings were affected by two significant events. The first was
the Dec. 30, 2005 sale of a wholly owned subsidiary, Government e-Management
Solutions, Inc. (GEMS), resulting in a pre-tax gain of $1,336,000. Including the
gain, GEMS generated $518,000 in net income for the quarter, with those results
reclassified as discontinued operations. Second, the company recognized the
impairment of its equity investment in an image processing company, resulting in
a $3,100,000 pre-tax loss. This investment was made in 2001 to acquire imaging
technology for the company's payment operations. Accumulated losses resulted in
the one-time charge.

4th Quarter Revenues from Core Operations Up Strongly

      Overall, 2005 fourth quarter pre-tax income from core operations, which
excludes the $3,100,000 impairment charge, increased $1,780,000 or 43% over the
corresponding period in 2004. Income from


                                       5

continuing operations before taxes, which includes the impairment charge, decreased $1,320,000 or 32%. Total revenue from continuing operations was up 17% or $2,747,000 over the year-earlier period. Payment and processing fees led the way with a 20% or $1,592,000 year-to-year increase. Transportation invoices were up 11% and dollar volume rose 32% due to new business and heightened activity from existing accounts. New customer growth also led to an 8% increase in utility transactions and a 42% increase in dollars processed. The company's telecom group, acquired in August 2004, also contributed to the increase in payment and processing results. Net investment income increased 25% or $1,837,000 due to growth in funds generated from payment processing activities and the rise in prevailing interest rates. Total operating expenses were up 8% or $967,000 due mainly to the growth of expenses related to the increased processing activity. 2005 Summary Income from core operations before taxes and the $3,100,000 impairment charge increased $5,236,000 or 37% from 2004. Income from continuing operations before taxes, which includes the impairment charge, increased $2,136,000 or 15%. Total revenues from continuing operations rose $10,307,000 or 17% in 2005 as Cass boosted processing volumes, fee revenues and investment income. Operating expenses from continuing operations were up 11% or $5,071,000 due mainly to the increased processing activity and the telecom acquisition. "Our earnings growth of 36% in 2005 reflects the intrinsic strength of our core businesses, the soundness of our business strategy and a generally favorable economic climate," commented Lawrence A. Collett, Cass chief executive officer and chairman. "The sale of GEMS, a non-core asset, and the write-off reinforces an already solid balance sheet and sets the stage for future growth. As we look ahead to 2006, we believe double-digit growth in net income is attainable." 6
