Forward-Looking Statements

When used in this press release and in other documents filed or furnished by Great Southern Bancorp, Inc. (the “Company”) with the Securities and Exchange Commission (the "SEC"), in the Company's press releases or other public or stockholder communications, and in oral statements made with the approval of an authorized executive officer, the words or phrases “may,” “might,” “could,” “should,” "will likely result," "are expected to," "will continue," "is anticipated," “believe,” "estimate," "project," "intends" or similar expressions are intended to identify "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements also include, but are not limited to, statements regarding plans, objectives, expectations or consequences of announced transactions, known trends and statements about future performance, operations, products and services of the Company. The Company’s ability to predict results or the actual effects of future plans or strategies is inherently uncertain, and the Company’s actual results could differ materially from those contained in the forward-looking statements. The novel coronavirus disease, or COVID-19, pandemic is adversely affecting the Company, its customers, counterparties, employees, and third-party service providers, and the ultimate extent of the impacts on the Company’s business, financial position, results of operations, liquidity, and prospects is uncertain. Continued deterioration in general business and economic conditions, including further increases in unemployment rates, or turbulence in domestic or global financial markets could adversely affect the Company’s revenues and the values of its assets and liabilities, reduce the availability of funding, lead to a tightening of credit, and further increase stock price volatility. In addition, changes to statutes, regulations, or regulatory policies or practices as a result of, or in response to, COVID-19, could affect the Company in substantial and unpredictable ways.

Other factors that could cause or contribute to such differences include, but are not limited to: (i) expected revenues, cost savings, earnings accretion, synergies and other benefits from the Company's  merger and acquisition activities might not be realized within the anticipated time frames or at all, and costs or difficulties relating to integration matters, including but not limited to customer and employee retention, might be greater than expected; (ii) changes in economic conditions, either nationally or in the Company's market areas; (iii) fluctuations in interest rates; (iv) 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 loan losses; (v) the possibility of other-than-temporary impairments of securities held in the Company's securities portfolio; (vi) the Company's ability to access cost-effective funding; (vii) fluctuations in real estate values and both residential and commercial real estate market conditions; (viii) the ability to adapt successfully to technological changes to meet customers' needs and developments in the marketplace; (ix) the possibility that security measures implemented might not be sufficient to mitigate the risk of a cyber-attack or cyber theft, and that such security measures might not protect against systems failures or interruptions; (x) legislative or regulatory changes that adversely affect the Company's business, including, without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and its implementing regulations, the overdraft protection regulations and customers' responses thereto and the Tax Cut and Jobs Act; (xi) changes in accounting policies and practices or accounting standards, including Accounting Standards Update 2016-13, Credit Losses (Topic 326), “Measurement of Credit Losses on Financial Instruments,” commonly referenced as the Current Expected Credit Loss model, which, upon adoption, is expected to result in an increase in the Company’s allowance for credit losses; (xii) monetary and fiscal policies of the Federal Reserve Board and the U.S. Government and other governmental initiatives affecting the financial services industry; (xiii) results of examinations of the Company and Great Southern Bank by their regulators, including the possibility that the regulators may, among other things, require the Company to limit its business activities, change its business mix, increase its allowance for loan losses, write-down assets or increase its capital levels, or affect its ability to borrow funds or maintain or increase deposits, which could adversely affect its liquidity and earnings; (xiv) costs and effects of litigation, including settlements and judgments; (xv) competition; (xvi) uncertainty regarding the future of LIBOR; and (xvii) natural disasters, war, terrorist activities or civil unrest and

their effects on economic and business environments in which the Company operates. The Company wishes to advise readers that the factors listed above and other risks described from time to time in documents filed or furnished by the Company with the SEC could affect the Company's financial performance and could 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.
