Forward-Looking Statements and Non-GAAP Financial Measures Forward-Looking Statements. Certain statements by Simmons First National Corporation (the "Company", which where appropriate includes the Company's wholly-owned banking subsidiary, Simmons Bank) contained in this presentation may not be based on historical facts and should be considered "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995.

Readers are cautioned not to place undue reliance on the forward-looking statements contained in this presentation in that actual results could differ materially from those indicated in or implied by such forward-looking statements due to a variety of factors. These factors include, but are not limited to, changes in the Company's operating or expansion strategy; the availability of and costs associated with obtaining adequate and timely sources of liquidity; changes in credit quality; changes in general market and economic conditions; changes in the investment environment and the market for debt securities, including prices therein; increased unemployment; labor shortages; possible adverse rulings, judgments, fines, settlements and other outcomes of pending or future litigation; the ability of the Company to collect amounts due under loan agreements; significant increases in nonaccrual loan balances; changes in consumer preferences and loan demand; the effectiveness of the Company's interest rate risk management strategies; laws and regulations affecting financial institutions in general or relating to taxes; the effect of pending or future legislation; changes in governmental administrations; the ability of the Company to repurchase its common stock on favorable terms; the ability of the Company to successfully manage and implement its acquisition strategy and integrate acquired institutions; changes in tariff policies; difficulties and delays in integrating an acquired business or fully realizing cost savings and other benefits of mergers and acquisitions; changes in interest rates, deposit flows, real estate values, and capital markets; increased inflation; customer acceptance of the Company's products and services and changes in customer behaviors; changes or disruptions in technology and IT systems (including cyber or other information technology threats, attacks and events); changes in accounting principles relating to loan loss recognition (current expected credit losses, or CECL); fraud that results in material losses or that we have not discovered yet that may result in material losses; the benefits associated with the Company's early retirement program; pandemics or significant health hazards, severe weather conditions, natural disasters, terrorist activities, political crises, war, and other military conflicts (including the ongoing military conflicts between Russia and Ukraine and between Israel and Iran) or other major events, or the prospect of these events; increased competition in the markets in which the Company operates and from non-bank financial institutions; changes in governmental policies; loss of key employees; reliance on third parties for key services; the soundness of other financial institutions and any indirect exposure related to the closings of other financial institutions and their impact on the broader market through other customers, suppliers and partners, or that the conditions which resulted in the liquidity concerns experienced by closed financial institutions may also adversely impact, directly or indirectly, other financial institutions and market participants with which the Company has commercial or deposit relationships; increased delinquency and foreclosure rates on commercial real estate and other loans; and other risk factors. Other relevant risk factors are detailed in the Company's Form 10-K for the year ended December 31, 2024, the Company's Form 10-Q for the quarter ended June 30, 2025, and other reports that the Company has filed with or furnished to the U.S. Securities and Exchange Commission (the SEC), all of which are available from the SEC on its website, www.sec.gov. In addition, there can be no guarantee that the board of directors ("Board") of the Company will approve a quarterly dividend in future quarters, and the timing, payment, and amount of future dividends (if any) is subject to, among other things, the discretion of the Board and may differ significantly from past dividends. Any forward-looking statement speaks only as of the date of this presentation, and the Company undertakes no obligation to update these forward-looking statements to reflect events or circumstances that occur after the date of this presentation. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are based on hypothetical assumptions that may not accurately reflect future incomes, are not forecasts and are not guaranteed, and may differ significantly from actual results. Non-GAAP Financial Measures. This presentation contains financial information determined by methods other than in accordance with U.S. generally accepted accounting principles ("GAAP"). The Company's management uses these non-GAAP financial measures in their analysis of the Company's performance and capital adequacy. These measures adjust GAAP performance measures to, among other things, include the tax benefit associated with revenue items that are tax-exempt, as well as exclude from net income (including on a per share diluted basis), pre-tax, pre-provision earnings, net charge-offs, income available to common shareholders, non-interest income, and non-interest expense certain income and expense items attributable to, for example, merger activity (primarily including merger-related expenses), gains and/or losses on sale of branches, net branch right-sizing initiatives, early retirement program, termination of vendor and software services, FDIC special assessment charges and expenses related to the fraud event reported in the first quarter of 2025. In addition, the Company also presents certain figures based on tangible common stockholders' equity, tangible assets and tangible book value, which exclude goodwill and other intangible assets, and presents certain other figures to include the effect that accumulated other comprehensive income could have on the Company's capital levels. The Company further presents certain figures that are exclusive of the impact of deposits and/or loans acquired through acquisitions, mortgage warehouse loans, and/or energy loans, gains and/or losses on the sale of securities, or the Two Specific Credit Relationships. The Company's management believes that these non-GAAP financial measures are useful to investors because they, among other things, present the results of the Company's ongoing operations without the effect of mergers or other items not central to the Company's ongoing business, present the Company's capital inclusive of the potential impact of AOCI (primarily comprised of unrealized losses on securities), as well as normalize for tax effects and certain other effects. Management, therefore, believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of the Company's ongoing businesses, and management uses these non-GAAP financial measures to assess the performance of the Company's ongoing businesses as related to prior financial periods. These non-GAAP disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the appendix to this presentation. 2
