Company Release - 7/21/2003

POPLAR BLUFF, Mo.--(BUSINESS WIRE)--July 21, 2003--Southern Missouri Bancorp, Inc., ("Company") (NASDAQ: SMBC), the parent corporation of Southern Missouri Bank and Trust Co., today announced cash operating earnings, excluding the amortization of goodwill, of $750,000, or $.63 per diluted share for the quarter ended June 30, 2003, up from the $.57 per diluted share earned during the same period last year.

For fiscal 2003, cash operating earnings totaled $2.9 million or $2.42 per diluted share, up 19% from the $2.04 earned during the same period last year.

Net earnings for the fourth quarter of fiscal 2003 were $710,000, or $.60 per diluted share, an increase of 11% from the $.54 per diluted share earned during the same period of the prior year. These earnings resulted in a return on average assets of 1.02% and a return on average equity of 11.30% as compared to respective returns of .99% and 10.82% during the same period of the prior year. Net earnings for fiscal 2003 were $2.7 million, or $2.28 per diluted share, an increase of 19% from the $1.94 per diluted share earned during the prior year. These earnings provided a return on average assets and average common equity of 1.00% and 11.08%, as compared to the respective returns of .91% and 9.77% for fiscal 2002.

"We are pleased with the steady improvement in our earnings per share and return on equity over each of the last eight successive quarters," said Greg Steffens, President and CEO of Southern Missouri Bank & Trust Co. "We have been able to continue to expand earnings by increasing non-interest related income while controlling operating expenditures. We are pleased with the 62% growth in non-interest income this year due to the implementation of the overdraft privilege program, which allows our non-business checking account customers the ability to overdraw their account up to $400. The fees generated by this program have more than offset a contraction in our net interest rate spread. Over the last quarter, our spread was negatively impacted by increased loan and security prepayment rates, which hampered loan growth and lowered investment portfolio returns. We are also encouraged by the continued improvement in our overall credit quality, as delinquency levels and non-performing asset levels continue to decline during challenging national economic conditions. We are pleased to share the improvement in our earnings and our solid financial condition with our shareholders by increasing our common stock dividend for the second consecutive year. Overall, we expect the economic and interest-rate environment to remain challenging, but we believe our business plan will continue to generate shareholder value."

The Company's net interest income decreased $117,000 for the three-month period ended June 30, 2003, as compared to the same period of the prior year. The decrease was due to the compression of our interest rate spread, primarily from lower investment portfolio yields as indicated by the drop in average investment yields from 4.79% for the three-month period ended June 30, 2002, to 2.36% for the current quarter. The drop in investment yields was primarily due to the Company's strategy of maintaining an investment portfolio with an average life of less than three years, faster prepayment rates and the general decline in interest rates. The average interest rate spread for the three-month period ended June 30, 2003, was 3.14% as compared to 3.44% over the same period of the prior year. Net interest income increased $430,000 over the twelve-month period ended June 30, 2003, as compared to the same period of the prior year. The 4.9% increase was primarily due to increased average balances. For fiscal 2003, the average interest rate spread was 3.28% as compared to 3.33% over the same period of the prior year.

The Company's non-interest income increased $248,000 and $541,000 over the respective three and twelve-month period ended June 30, 2003, as compared to the same period of the prior year. The respective increases of 107.4% and 61.9% were primarily due to an expanded customer base, structural changes in the assessment of overdraft fees and the implementation in the third quarter of the overdraft privilege program, which resulted in increased banking service charges.

During fiscal 2003, the Company's total assets increased $13.2 million, or 5.0%, to $279.5 million at June 30, 2003. This growth was attributed primarily to an $11.6 million increase in the loan portfolio to $222.8 million. Changes in the composition of the loan portfolio included growth in commercial and consumer loans of $13.9 million and $2.0 million, respectively, partially offset by the $3.3 million decrease in residential loans. Asset growth has been funded primarily with deposit growth and FHLB advances, which have increased $5.6 million and $6.5 million, respectively, since June 30, 2002.

The Company's stockholders' equity increased $597,000, to $25.1 million at June 30, 2003, from $24.5 million at June 30, 2002. The increase was primarily due to net income, partially offset by stock repurchases and cash dividends.

The Company is also pleased to announce that the Board of Directors, on July 18, 2003, approved the first quarter dividend of $.18 per common share, up from $.14 per share. This 29% increase is payable on August 29, 2003, to shareholders of record at the close of business on August 15, 2003. The dividend is the Company's 37th consecutive quarterly dividend since the inception of the Company.

The Company has previously announced the intention to repurchase up to 58,720 shares of its common stock, or approximately 5% of its outstanding common shares. To date, the Company has repurchased 23,500 shares at an average cost of $25.06 per share. The Company will continue to repurchase shares of its common stock under this plan from time to time, subject to market conditions, business opportunities and other economic considerations, and the Company's determination of the most efficient use of capital in order to maximize shareholder value.

On June 30, 2003, the Company had 1,147,177 common shares outstanding. The common stock traded between $24.00 and $25.75 per share during the quarter ended June 30, 2003, with the last trade of the quarter occurring at $25.40. The Company, through its banking subsidiary, provides a wide array of financial services to Southeastern Missouri through its main office located in Poplar Bluff and seven other full-service facilities located in Poplar Bluff, Dexter, Qulin, Kennett, Doniphan, and Van Buren, Missouri.
