SOUTHERN MISSOURI BANCORP REPORTS PRELIMINARY RESULTS FOR FIRST QUARTER OF FISCAL 2020;

DECLARES QUARTERLY DIVIDEND OF $0.15 PER COMMON SHARE;

CONFERENCE CALL TO DISCUSS RESULTS SCHEDULED FOR TUESDAY, OCTOBER 22, AT 3:30PM CENTRAL TIME

Poplar Bluff, Missouri - Southern Missouri Bancorp, Inc. (“Company”) (NASDAQ: SMBC), the parent corporation of Southern Bank (“Bank”), today announced preliminary net income available to common stockholders for the first quarter of fiscal 2020 of $7.8 million, an increase of $1.0 million, or 15.1%, as compared to the same period of the prior fiscal year. The increase was attributable to increased net interest income and noninterest income, and partially offset by increases in noninterest expense, provision for income taxes, and provision for loan losses. Preliminary net income was $.85 per fully diluted common share for the first quarter of fiscal 2020, an increase of $.09 as compared to the $.76 per fully diluted common share reported for the same period of the prior fiscal year.

Highlights for the first quarter of fiscal 2020:

Annualized return on average assets was 1.40%, while annualized return on average common equity was 13.0%, as compared to 1.43% and 13.4%, respectively, in the same quarter a year ago, and 1.37% and 12.9%, respectively, in the fourth quarter of fiscal 2019, the linked quarter.

Earnings per common share (diluted) were $.85, up $.09, or 11.8%, as compared to the same quarter a year ago, and up $.04, or 4.9%, from the fourth quarter of fiscal 2019, the linked quarter.

Net loan growth for the first quarter of fiscal 2020 was $28.1 million, a moderate annualized pace of growth, but less than achieved by the Company in recent September quarters, typically its best of the year. In general, seasonal impacts have been less pronounced over the previous four quarters.

Deposit balances declined $21.2 million in the first quarter, in what is typically the Company’s weakest quarter for deposit growth. A reduction of $11.7 million in brokered time and nonmaturity deposits contributed to the overall decline.

Net interest margin for the first quarter of fiscal 2020 was 3.81%, down from the 3.92% reported for the year ago period, and up from the 3.77% figure reported for the fourth quarter of fiscal 2019, the linked quarter. Discount accretion on acquired loan portfolios was modestly reduced in the current quarter as compared to the linked quarter, and down significantly as compared to the year ago period, but these decreases were offset by recognition of unusual amounts of interest income as some loans classified as nonaccrual in the previous quarter were repaid, as discussed in detail below.

Noninterest income was up 19.6% for the first quarter of fiscal 2020, as compared to the year ago period, and up 9.6% as compared to the fourth quarter of fiscal 2019, the linked quarter.

Noninterest expense was up 13.2% for the first quarter of fiscal 2020, compared to the year ago period, and up 1.4% from the fourth quarter of fiscal 2019, the linked quarter. After reporting modest acquisition-related costs in the year-ago period, comparable charges were immaterial charges in the current and linked quarters.

Nonperforming assets were $17.9 million, or 0.80% of total assets, at September 30, 2019, as compared to $24.8 million, or 1.12% of total assets, at June 30, 2019. The decrease primarily reflected progress by the Company in resolving acquired nonperforming assets resulting from the November 2018 acquisition of Gideon Bancshares Company and its subsidiary, First Commercial Bank (“the Gideon Acquisition”).

Dividend Declared:

The Board of Directors, on October 15, 2019, declared a quarterly cash dividend on common stock of $0.15, payable November 29, 2019, to stockholders of record at the close of business on November 15, 2019, marking the 102^nd consecutive quarterly dividend since the inception of the Company. The Board of Directors and management believe the payment of a quarterly cash dividend enhances stockholder value and demonstrates our commitment to and confidence in our future prospects.

Balance Sheet Summary:

The Company experienced balance sheet growth in the first quarter of fiscal 2020, with total assets of $2.2 billion at September 30, 2019, reflecting an increase of $34.8 million, or 1.6%, as compared to June 30, 2019. Asset growth was comprised mainly of increases in loans and available-for-sale (“AFS”) securities, while cash equivalents were reduced.

AFS securities were $171.0 million at September 30, 2019, an increase of $5.5 million, or 3.3%, as compared to June 30, 2019. Cash equivalents and time deposits were a combined $32.4 million, a decrease of $4.0 million, or 10.9%, as compared to June 30, 2019.

Loans, net of the allowance for loan losses, were $1.9 billion at September 30, 2019, an increase of $28.1 million, or 1.5%, as compared to June 30, 2019. The portfolio primarily saw growth in commercial loan balances, funded balances in construction loans, and consumer loans, partially offset by declines in residential and commercial real estate loans. The increase in commercial loan balances was attributable primarily to growth in agricultural operating and equipment loan balances, some of which is seasonal, along with increases in commercial and industrial loan balances. Construction loan balances were increased as a result of both draws on existing construction loans and new loans. Growth in consumer loans consisted primarily of loans secured by deposits, and home equity line of credit balances. Residential real estate loan balances were lower as the Company saw reductions in loans secured by multifamily real estate, partially offset by an increase in loans secured by one- to four-family real estate. Commercial real estate loans were reduced slightly as payoffs on nonresidential properties were mostly offset by increases in loans secured by land and development ground. Loans anticipated to fund in the next 90 days stood at $101.7 million at September 30, 2019, as compared to $114.5 million at September 30, 2018, and $83.3 million at June 30, 2019.

Nonperforming loans were $14.0 million, or 0.74% of gross loans, at September 30, 2019, as compared to $21.0 million, or 1.13% of gross loans at June 30, 2019, and $7.6 million, or 0.46% of gross loans, at September 30, 2018. Nonperforming assets were $17.9 million, or 0.80% of total assets, at September 30, 2019, as compared to $24.8 million, or 1.12% of total assets, at June 30, 2019, and $12.5 million, or 0.64% of total assets, at September 30, 2018. The decrease in nonperforming loans since June 30, 2019, was attributed primarily to the resolution of certain nonperforming loans acquired in the Gideon Acquisition, which included nonperforming loans of $12.9 million as of the December 31, 2018, quarter end following the acquisition, while nonperforming loans from that acquisition total $8.0 million as of September 30, 2019. The decrease in nonperforming loans was also the principal reason for the decrease in nonperforming assets. Our allowance for loan losses at September 30, 2019,

totaled $20.7 million, representing 1.09% of gross loans and 148% of nonperforming loans, as compared to $19.9 million, or 1.07% of gross loans and 94.7% of nonperforming loans, at June 30, 2019. For all impaired loans, the Company has measured impairment under ASC 310-10-35. Management believes the allowance for loan losses at September 30, 2019, is adequate, based on that measurement.

Total liabilities were $2.0 billion at September 30, 2019, an increase of $30.9 million, or 1.6%, as compared to June 30, 2019.

Deposits were $1.9 billion at September 30, 2019, a decrease of $21.2 million, or 1.1%, as compared to June 30, 2019. The decrease was attributable to public unit deposits, which decreased by $24.0 million during the first quarter of fiscal 2020, and totaled $242.8 million at September 30, 2019. The decrease was also attributable in part to a reduction in brokered deposits, which declined on net by $11.7 million, reflecting a decrease in brokered time deposits of $19.5 million, and an increase in brokered nonmaturity deposits of $7.8 million. Brokered time deposits were $25.4 million, and brokered nonmaturity deposits were $16.1 million, at September 30, 2019. In total, deposit balances saw reductions in certificates of deposit, noninterest-bearing transaction accounts, interest-bearing transaction accounts, and savings accounts, partially offset by growth in money market deposit accounts. The average loan-to-deposit ratio for the first quarter of fiscal 2020 was 99.2%, as compared to 101.6% for the same period of the prior fiscal year.

FHLB advances were $103.3 million at September 30, 2019, an increase of $58.4 million, or 130.1%, as compared to June 30, 2019, with the increase attributable to the Company’s use of this funding source to replace brokered deposits, and to fund loan growth in what is typically a seasonally slow first fiscal quarter for deposit growth. The increase consisted of $52.6 million in overnight funding and $5.8 million in term advances. Over the past several years, the Company has worked to move public unit and business customers from a swept repurchase agreement product, which required the use of the Company’s AFS securities portfolio to provide the securities to collateralize those borrowings, to a reciprocal deposit product. During the first quarter of fiscal 2020, the final customers utilizing the sweep product were migrated.

The Company’s stockholders’ equity was $242.3 million at September 30, 2019, an increase of $3.9 million, or 1.6%, as compared to June 30, 2019. The increase was attributable to retained earnings, and an increase in accumulated other comprehensive income, which was due to a decrease in market interest rates, partially offset by cash dividends paid and by repurchases of 86,050 Company shares, acquired for $2.8 million, for an average price of $32.70 per share.

Quarterly Income Statement Summary:

The Company’s net interest income for the three-month period ended September 30, 2019, was $19.6 million, an increase of $2.4 million, or 13.9%, as compared to the same period of the prior fiscal year. The increase was attributable primarily to a 17.2% increase in the average balance of interest-earning assets, partially offset by a decrease in net interest margin to 3.81% in the current three-month period, from 3.92% in the three-month period a year ago.

Loan discount accretion and deposit premium amortization related to the Company’s August 2014 acquisition of Peoples Bank of the Ozarks (Peoples), the June 2017 acquisition of Capaha Bank (Capaha), the February 2018 acquisition of Southern Missouri Bank of Marshfield (SMB-Marshfield), and the Gideon Acquisition resulted in an additional $508,000 in net interest income for the three-month period ended September 30, 2019, as compared to $1.2 million in net interest income for the same period a year ago. In the year ago period, there were significant impacts from the favorable resolution of specific purchased credit impaired loans obtained in the Peoples and Capaha acquisitions, and no accretion from the Gideon Acquisition, which did not close until the second quarter of fiscal 2019. Combined, these components of net interest income contributed ten basis points to net interest margin in the three-month period ended September 30, 2019, as compared to a contribution of 27

basis points for the same period of the prior fiscal year. For the linked quarter, ended June 30, 2019, when net interest margin was 3.77%, comparable discount accretion contributed 12 basis points to the net interest margin. Over the longer term, the Company expects this component of net interest income to decline, although to the extent that we have periodic resolutions of specific credit impaired loans, this may create volatility in this component of net interest income. Also, the Company recognized an additional $414,000 in interest income as a result of the resolution of nonperforming loans during the current period. This recognition of interest income contributed eight basis points to the net interest margin, without material comparable items in the year ago or linked period.

The provision for loan losses for the three-month period ended September 30, 2019, was $896,000, as compared to $682,000 in the same period of the prior fiscal year. Increased provisioning was attributed primarily to increasing loan balances subject to allowance methodology, as acquired loan balances mature and prepay, and are replaced by new loan production, or are refinanced by the Company. The Company saw continued low levels of net charge offs and a stable outlook regarding the credit quality of the Company’s legacy loan portfolio. As a percentage of average loans outstanding, the provision for loan losses in the current three-month period represented a charge of 0.19% (annualized), while the Company recorded net charge offs during the period of 0.02% (annualized). During the same period of the prior fiscal year, the provision for loan losses as a percentage of average loans outstanding represented a charge of 0.17% (annualized), while the Company recorded net charge offs of 0.03% (annualized).

The Company’s noninterest income, for the three-month period ended September 30, 2019, was $4.1 million, an increase of $671,000, or 19.6%, as compared to the same period of the prior fiscal year. Increases in bank card interchange income, deposit account service charges, wealth management and insurance brokerage commissions, and gains realized on sales of residential loans originated for sale into the secondary market were partially offset by decreases in loan fees and mortgage servicing income.

Noninterest expense for the three-month period ended September 30, 2019, was $13.0 million, an increase of $1.5 million, or 13.2%, as compared to the same period of the prior fiscal year. The increase was attributable primarily to increases in compensation and benefits, occupancy expenses, and bank card network expense, partially offset by decreases in deposit insurance premiums and legal and professional fees. Noninterest expense items were generally increased as a result of additional staff, facilities, and transactions following the Gideon Acquisition. Partially offsetting these increases, in September 2019, the FDIC began applying credits to the deposit insurance assessments due from smaller banks, such as the Company’s subsidiary. These credits represented the costs borne by smaller banks over several years to increase the deposit insurance fund ratio as required under the Dodd-Frank Act. As a result, we recognized no deposit insurance premium expense for the current quarter, as compared to an expense of $138,000 in the year ago period. Provided the deposit insurance fund ratio remains above 1.35%, the Company would expect to recognize no deposit insurance premium expense in the quarter which will end December 31, 2019, and a reduced expense in the quarter which will end March 31, 2020, before the expense returns to a normalized level for the quarter ended June 30, 2020. After recording $175,000 in charges related to merger and acquisition activity in the same quarter a year ago, there were no comparable expenses in the current period. The Company realized a reduced off-balance sheet credit exposure, resulting in a recovery of $146,000 in the current period, as compared to a charge of $23,000 in the year ago period. The efficiency ratio for the three-month period ended September 30, 2019, was 54.8%, as compared to 55.6% in the same period of the prior fiscal year.

The income tax provision for the three-month period ended September 30, 2019, was $2.0 million, an increase of $310,000, or 18.6%, as compared to the same period of the prior fiscal year, attributable primarily to higher pre-tax income, combined with an increase in the effective tax rate, to 20.2%, as compared to 19.7% in the year-ago period.
