Poplar Bluff, Missouri, Oct. 21, 2026 -- Southern Missouri Bancorp, Inc. (“Company”) (NASDAQ: SMBC), the parent corporation of Southern Bank (“Bank”), today announced preliminary net income for the first quarter of fiscal 2027 of $19.1 million, an increase of $3.4 million, or 22.0%, as compared to the same period of the prior fiscal year. The increase was driven by higher net interest income, lower provision for credit losses (PCL), and higher noninterest income. This was partially offset by higher noninterest expense and higher provision for income taxes. Preliminary net income was $1.73 per fully diluted common share for the first quarter of fiscal 2027, an increase of $0.35, or 25.4%, as compared to $1.38 per fully diluted common share reported for the same period of the prior fiscal year.
