Exhibit 99.1 NEWS RELEASE FOR IMMEDIATE RELEASE Contact: Daniel L. Krieger, President (515) 232-6251 APRIL 18, 2003 AMES NATIONAL CORPORATION ANNOUNCES FIRST QUARTER 2003 FINANCIAL RESULTS AND FORECASTED EARNINGS FOR 2003 The Company earned net income of $2,870,000, or $0.92 per share for the three months ended March 31, 2003, compared to net income of $2,941,000, or $0.94 per share, for the three months ended March 31, 2002, a decrease of 2%. The Company's return on average assets was 1.67% and 1.91%, respectively, for the three-month periods ending March 31, 2003 and 2002. The Company's return on average equity was 11.26% and 12.26%, respectively for the three-month periods ending March 31, 2003 and 2002. Total assets increased from $646 million for the quarter ended March 31, 2002 to $737 million for the quarter ended March 31, 2003, an increase of 14%. While net interest income was relatively unchanged for the first quarter of 2003 compared to the same period in 2002, non-interest expense was significantly higher in 2003 as a result of higher overhead expenses associated with the opening of United Bank & Trust NA (United Bank) in Marshalltown, Iowa. Noninterest expenses for United Bank totaled $324,000 for the quarter ended March 31, 2003. The higher non-interest expense was partially offset by higher securities gains in the Company's investment portfolio and an increase in secondary market fees for the first quarter of 2003 compared to the same period a year ago. Secondary mortgage market activity continues to be strong at affiliate banks, but is not anticipated to remain at current levels once interest rates begin to increase. Loans increased 12% to $340 million, a $36 million increase since March 31, 2002. Commercial real estate loans accounted for most of the growth with United Bank generating the increase. Deposits showed a strong 16% growth over first quarter 2002 with all interest bearing deposit categories reflecting significant growth. United Bank has made an impact in the Marshalltown area with over $46 million in deposits since it began operations in mid June 2002. Capital increased 8% to 103 million from one year ago, which included over $7 million in net unrealized gains on securities available for sale. Capital at the end of March 2003, represented 14% of total assets. Ames National Corporation stock, under the symbol ATLO, traded in the $46.05 to $48.90 range in the first quarter of 2003 and closed at $48.90 on March 31, 2003. Ames National Corporation is forecasting earnings for the year ending December 31, 2003 of $3.27 per share. This figure compares to the $3.63 per share earned for the year ending December 31, 2002. Lower earnings are forecast as a result of operating costs associated with the de novo chartering of United Bank & Trust in Marshalltown, Iowa, and anticipation of lower net interest margins in 2003. Ames National Corporation affiliate banks are located in Iowa and include First National Bank, Ames; Boone Bank & Trust Co., Boone; State Bank & Trust Co., Nevada; Randall-Story State Bank, Story City; and United Bank & Trust, Marshalltown. The Company's earnings forecast for 2003 is a forward-looking statement under the Private Securities Litigation Reform Act of 1995 that is subject to certain risks and uncertainties that could cause the actual earnings to differ materially from forecasted earnings. A number of factors, many of which are beyond the Company's control, could cause actual earnings to differ significantly from those described in this forward-looking statement. Such risks and uncertainties with respect to the Company include those related to the economic environment, particularly in the areas in which the Company and the Banks operate, competitive products and pricing, fiscal and monetary policies of the U.S. government, changes in governmental regulations affecting financial institutions, including regulatory fees and capital requirements, changes in prevailing interest rates, credit risk management and asset/liability management, the financial and securities markets and the availability of and costs associated with sources of liquidity. 1 AMES NATIONAL CORPORATION AND SUBSIDIARIES Consolidated Balance Sheets (unaudited) March 31, March 31, Assets 2003 2002 ------------------------------ Cash and due from banks ........................................................ $ 26,870,928 $ 40,864,403 Federal funds sold ............................................................. 100,320,000 60,960,000 Interest bearing deposits in financial institutions ............................ 1,000,000 600,000 Securities available-for-sale .................................................. 254,003,860 225,187,867 Loans receivable, net .......................................................... 340,383,399 304,510,264 Bank premises and equipment, net ............................................... 8,623,103 7,483,997 Accrued income receivable ...................................................... 5,701,244 5,836,053 Other assets ................................................................... 357,811 324,837 ------------------------------ Total assets ....................................................... $ 737,260,345 $ 645,767,421 ============================== Liabilities and Stockholders' Equity Deposits: Demand ..................................................................... $ 61,686,441 $ 51,991,931 NOW accounts ............................................................... 144,079,506 131,319,934 Savings and money market ................................................... 174,326,939 145,667,064 Time, $100,000 and over .................................................... 63,441,854 49,064,946 Other time ................................................................. 170,359,656 152,358,206 ------------------------------ Total deposits ..................................................... 613,894,396 530,402,081 Federal funds purchased and securities sold under agreements to repurchase ........................................ 13,362,019 13,830,133 Dividends payable .............................................................. 1,376,752 1,312,596 Deferred taxes ................................................................. 2,539,121 1,224,826 Accrued interest and other liabilities ......................................... 3,454,538 3,685,309 ------------------------------ Total liabilities .................................................. 634,626,826 550,454,945 ------------------------------ Stockholders' Equity: Common stock, $5 par value; authorized 6,000,000 shares; issued 3,153,230 shares at March 31, 2003 and 2002; outstanding 3,128,982 and 3,125,229 at March 31, 2003 and 2002, respectively .................................... 15,766,150 15,766,150 Surplus .................................................................... 25,354,014 25,393,028 Retained earnings .......................................................... 55,411,117 51,025,345 Treasury stock, at cost; 24,248 and 28,001 shares at March 31, 2003 and 2002, respectively ....................................
