(the "Company"). These forward-looking statements relate to our financial condition, results of operations, and may include, without limitation, statements with respect to anticipated future operating and financial performance, growth opportunities, interest rates, cost savings and funding advantages expected or anticipated to be realized by management. Words such as "may," "could," "should," "would," "believe," "anticipate," "estimate," "expect," "intend," "plan" and similar expressions are intended to identify these forward-looking statements. Forward-looking statements by the Company and its management are based on beliefs, plans, objectives, goals, expectations, anticipations, estimates and intentions of management and are not guarantees of future performance. The important factors we discuss below, as well as other factors discussed under the caption "Management's Discussion and Analysis of Financial Condition and Results of Operations" and identified in our Annual Report on Form 10-K and in our other filings with the SEC and those presented elsewhere by our management from time to time, could cause actual results to differ materially from those indicated by the forward-looking statements made in this document: expected cost savings, synergies and other benefits from our merger and acquisition activities, including our recently completed acquisitions, might not be realized within the anticipated time frames, to the extent anticipated, or at all, and costs or difficulties relating to integration matters, including but not limited to customer and employee retention and labor shortages, might be greater than expected and goodwill impairment charges might be incurred; potential adverse impacts to economic conditions both nationally and in our local market areas, other markets where the Company has lending relationships, or other aspects of the Company's business operations or financial markets, including, without limitation, as a result of employment levels, labor shortages and the effects of inflation, a potential recession or slowed economic growth; the strength of the United States economy in general and the strength of the local economies in which we conduct operations; fluctuations in interest rates and inflation, including the effects of a potential recession whether caused by Federal Reserve actions or otherwise or slowed economic growth caused by changes in oil prices or supply chain disruptions; the impact of monetary and fiscal policies of the Board of Governors of the Federal Reserve System (the "Federal Reserve Board") and the U.S. Government and other governmental initiatives affecting the financial services industry; potential imposition of new or increased tariffs or changes to existing trade policies that could affect economic activity or specific industry sectors; the impact of bank failures or adverse developments at other banks and related negative press about the banking industry in general on investor and depositor sentiment; the risks of lending and investing activities, including changes in the level and direction of loan delinquencies and write-offs and changes in estimates of the adequacy of the allowance for credit losses on loans; our ability to access cost-effective funding and maintain sufficient liquidity; the timely development of and acceptance of our new products and services and the perceived overall value of these products and services by users, including the features, pricing and quality compared to competitors' products and services; fluctuations in real estate values and both residential and commercial real estate markets, as well as agricultural business conditions; fluctuations in the demand for loans and deposits, including our ability to attract and retain deposits the impact of a federal government shutdown; legislative or regulatory changes that adversely affect our business; the effects of climate change, severe weather events, other natural disasters, war, terrorist activities or civil unrest and their effects on economic and business environments in which the Company operates; changes in accounting principles, policies, or guidelines results of examinations of us by our regulators, including the impact on FDIC insurance premiums and the possibility that our regulators may, among other things, require an increase in our reserve for credit losses on loans or a write-down of assets; the impact of technological changes and an inability to keep pace with the rate of technological advances; the inability of key third party providers to perform their obligations to us; cyber threats, such as phishing, ransomware, and insider attacks, can lead to financial loss, reputational damage, and regulatory penalties if sensitive customer data and critical infrastructure are not adequately protected or ability to retain key members of our management team; and our success at managing the risks involved in the foregoing.

The Company wishes to advise readers that the factors listed above and other risks described in our Annual Report on Form 10-K, including, without limitation, those described under Item 1A. "Risk Factors," and other documents filed or furnished from time to time by the Company with the SEC (and are available on our website at investors.bankwithsouthern.com and on the SEC's website at www.sec.gov) could affect the Company's financial performance and cause the Company's actual results for future periods to differ materially from any opinions or statements expressed with respect to future periods in any current statements. We undertake no obligation to publicly update or revise any forward-looking statements or to update the reasons why actual results could differ from those contained in such statements, whether as a result of new information, future events or otherwise. In light of these risks, uncertainties and assumptions, the forward-looking statements discussed might not occur, and you should not put undue reliance on any forward-looking statements. Financial Data Financial information presented as of and for the first quarter fiscal 2026 and as of September 30, 2025, is provided on a preliminary basis and is unaudited. Non-GAAP Financial Measures Tangible common equity, tangible book value per common share, core diluted earnings per common share, and core net interest margin are financial measures determined by methods other than in accordance with accounting principles generally accepted in the United States (GAAP). These non-GAAP financial measures are supplemental and not a substitute for an analysis based on GAAP measures. As other companies may use different calculations for these measures, this presentation may not be comparable to other similarly titled measures used by other companies. We calculate tangible common equity by excluding the balance of intangible assets from common stockholders' equity. We calculate tangible book value per common share by dividing tangible common equity by common shares outstanding, less restricted common shares not vested, as compared to book value per common share, which we calculate by dividing common stockholders' equity by common shares outstanding, less restricted common shares not vested. We believe that this is consistent with the treatment by bank regulatory agencies, which generally exclude intangible assets from the calculation of risk-based capital ratios. We calculate core diluted earnings per common share by excluding from net interest income the accretion of fair value discount on the acquired loan portfolio and amortization of fair value premium on the acquired time deposit portfolio resulting from the fiscal 2015 Peoples acquisition, the fiscal 2017 Capaha acquisition, the fiscal 2018 SMB-Marshfield acquisition, the fiscal 2019 First Commercial acquisition, the fiscal 2020 Central acquisition, the fiscal 2022 FortuneBank acquisition, and the fiscal 2023 Citizens acquisition. We also exclude from noninterest expense the acquisition expenses we incurred during fiscal years 2020, 2022, 2023 and 2024 year to date resulting from these acquisitions. We believe that core diluted earnings per common share is useful in assessing our core operating performance, particularly when comparing periods or when comparing our operating performance to the operating performance of our industry peers. We calculate core net interest margin by excluding from net interest income the accretion of fair value discount on the acquired loan portfolio and amortization of fair value premium on the acquired time deposit portfolio resulting from the Peoples acquisition, the Capaha acquisition, the SMB-Marshfield acquisition, the First Commercial acquisition, the Central acquisition, the FortuneBank acquisition, and the Citizens acquisition. We believe that each of these non-GAAP financial measures provides information that is important to investors and that is useful in understanding our capital position and ratios. Reconciliations of the non-GAAP measures of tangible common equity, tangible book value per common share, core diluted earnings per common share, and core net interest margin to the GAAP measures of common stockholders' equity, book value per common share, diluted earnings per common share, and net interest margin are set forth below.
