Non-GAAP Financial Measures Non-GAAP Financial Measures This press release, including the accompanying financial statement tables, contains financial information determined by metho ds other than in accordance with generally accepted accounting principles, or GAAP. This financial information includes certain operating performance measures, which exclude charges that are not considered part of recurring operations. Non-GAAP measures in this press release include, but are not limited to, descriptions such as “operating net income,” “operating earnings (loss) per share,” “tangible book value per common share,” “operating return on average common equity,” “operating return on average assets,” and “operating efficiency ratio.” In addition, this press release, consistent with SEC Industry Guide 3, presents total revenue, net interest income, net interest margin, and efficiency ratios on a fully taxable equivalent (“FTE”) basis, and ratios on an annualized basis. The FTE basis adjusts for the tax-favored status of net interest income from certain loans and investments using a federal tax rate of 21% for all periods beginning on or after January 1, 2018 and 35% for all periods prior to January 1, 2018, as well as state income taxes, where applicable, to increase tax-exempt interest income to a taxable-equivalent basis. MidSouth believes this measure to be the preferred industry measurement of net interest income and it enhances comparability of net interest income arising from taxable and tax -exempt sources. We use non-GAAP measures because we believe they are useful for evaluating our financial condition and performance over periods of time, as well as in managing and evaluating our business and in discussions about our performance. We also believe these non-GAAP financial measures provide users of our financial information with a meaningful measure for assessing our financial condition as well as comparison to financial results for prior periods. These measures should be viewed in addition to, and not as an alternative to or substitute for, measures determined in accordance with GAAP, and are not necessarily comparable to non-GAAP measures that may be presented by other companies. To the extent applicable, reconciliations of these non-GAAP measures to the most directly comparable measures as reported in accordance with GAAP are included with the accompanying financial statement tables.

Forward-Looking Statements Disclosure Certain statements contained herein are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934 and subject to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, which involve risks and uncertainties. These statements include, among others, statements regarding expected future performance and shareholder value. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “may,” “plan,” “will,” “would,” “could,” “should,” “guidance,” “potential,” “continue,” “project,” “forecast,” “confident,” and similar expressions are typically used to identify forward-looking statements. These statements are based on assumptions and assessments made by management in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe to be appropriate. Any forward-looking statements are not guarantees of our future performance and are subject to risks and uncertainties and may be affected by various factors that may cause actual results, developments and business decisions to differ materially from those in the forward-looking statements. Factors that might cause such a difference include, among other matters, changes in interest rates and market prices that could affect the net interest margin, asset valuation, and expense levels; changes in local economic and business conditions in the markets we serve, including, without limitation, changes related to the oil and gas industries that could adversely affect customers and their ability to repay borrowings under agreed upon terms, adversely affect the value of the underlying collateral related to their borrowings, and reduce demand for loans; increases in competitive pressure in the banking and financial services industries; increased competition for deposits and loans which could affect compositions, rates and terms; changes in the levels of prepayments received on loans and investment securities that adversely affect the yield and value of the earning assets; our ability to successfully implement and manage our strategic initiatives; costs and expenses associated with our strategic initiatives and regulatory remediation efforts and possible changes in the size and components of the expected costs and charges associated with our strategic initiatives and regulatory remediation efforts; our ability to realize the anticipated benefits and cost savings from our strategic initiatives within the anticipated time frame, if at all; the ability of the Company to comply with the terms of the formal agreement and the consent order with the Office of the Comptroller of the Currency; risk of noncompliance with and further enforcement actions regarding the Bank Secrecy Act and other anti-money laundering statues and regulations; credit losses due to loan concentration, particularly our energy lending and commercial real estate portfolios; a deviation in actual experience from the underlying assumptions used to determine and establish our allowance for loan and lease losses (“ALLL”), which could result in greater than expected loan losses; the adequacy of the level of our ALLL and the amount of loan loss provisions required in future periods including the impact of implementation of the new CECL (current expected credit loss) methodology; future examinations by our regulatory authorities, including the possibility that the regulatory authorities may, among other things, impose additional enforcement actions or conditions on our operations, require additional regulatory remediation efforts or require us to increase our allowance for loan losses or write-down assets; changes in the availability of funds resulting from reduced liquidity or increased costs; the timing and impact of future acquisitions or divestitures, the success or failure of integrating acquired operations, and the ability to capitalize on growth opportunities upon entering new markets; the ability to acquire, operate, and maintain effective and efficient operating systems; the identified material weaknesses in our internal control over financial reporting; increased asset levels and changes in the composition of assets that would impact capital levels and regulatory capital ratios; loss of critical personnel and the challenge of hiring qualified personnel at reasonable compensation levels; legislative and regulatory changes, including the impact of regulations under the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and other changes in banking, securities and tax laws and regulations and their application by our regulators, changes in the scope and cost of FDIC insurance and other coverage; regulations and restrictions resulting from our participation in government-sponsored programs such as the U.S. Treasury’s Small Business Lending Fund, including potential retroactive changes in such programs; changes in accounting principles, policies, and guidelines applicable to financial holding companies and banking; increases in cybersecurity risk, including potential business disruptions or financial losses; acts of war, terrorism, cyber intrusion, weather, or other catastrophic events beyond our control; and other factors discussed under the heading “Risk Factors” in MidSouth’s Annual Report on Form 10-K for the year ended December 31, 2018 filed with the SEC on March 18, 2019 and in its other filings with the SEC. MidSouth does not undertake any obligation to publicly update or revise any of these forward-looking statements, whether to reflect new information, future events or otherwise, except as required by law.
