Exhibit 99 For Immediate Release Contact: Kathleen Bruegenhemke Senior Vice President, Investor Relations TEL: 573.761.6100 FAX: 573.761.6272 EXCHANGE NATIONAL BANCSHARES, INC. OF JEFFERSON CITY, MISSOURI, ANNOUNCES 3rd QUARTER EARNINGS OF $0.49 PER DILUTED SHARE JEFFERSON CITY, MO, October 29, 2004 - Today, Exchange National Bancshares, Inc. (NASDAQ: EXJF) reported third quarter earnings of $0.49 per diluted share, down 18% from diluted earnings per share of $0.60 a year ago. Net income for the 3 months ended September 30, 2004 of $2,056,000 decreased $488,000 when compared to the third quarter of 2003. For the nine months ended September 30, 2004, Exchange National Bancshares earned $1.54 per diluted share, down 7% from diluted earnings per share of a year earlier. Net income for the nine months ended September 30, 2004 of $6,479,000 decreased $464,000 when compared to the first nine months of 2003. In commenting on earnings, James E. Smith, Chairman and CEO said, "Year to date net interest income increased $1,282,000 compared to the same period in 2003 due to an increase in the volume of earning assets. Increases in net interest income were offset by a $970,000 decrease in non-interest income and a $1,165,000 increase in non-interest expense which is primarily associated with increased staffing in our retail network, expenses associated with the timing of tax payments on the company's real estate investment trust and costs incurred to document internal controls as required by newly imposed Sarbanes-Oxley regulation. The decrease in other non-interest income results largely from reduced gains on sale of mortgage loans due to fewer refinancings." For the year, return on average equity was 9.61% and the return on average assets was 0.97%. Comparing September 30, 2004 balances to December 31, 2003, total assets increased 1.1% to $884,943,000. Total loans grew 5.4% to $615,256,000, while investment securities decreased 11.7% to $166,810,000. Total deposits increased 3.4% to $687,966,000. During the same period, stockholders' equity increased 4.1% to $91,403,000 or 10.3% of total assets.
