This document 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 . 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 income available to common shareholders, non - interest income, and non - interest expense certain expenses related to significant non - core activities, such as merger - related expenses, expenses related to the Company’s early retirement program, gain on sale of branches, and net branch right - sizing expenses . 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 . The Company further presents certain figures that are exclusive of the impact of PPP loans . The Company’s management believes that these non - GAAP financial measure 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, as well as normalize for tax 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 core businesses . 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 .

Category Q1 - 21 Linked Quarter Change Management’s Outlook Interest Income Down $9.7 million Primarily driven by lower loan volume and a $2.4 million decrease in accretion income, which was partially offset by a $4.4 million increase in the security portfolio. Management anticipates the following for the balance of 2021: 1) Organic loan growth in the mid single digits for Second Half 2021 2) PPP balances to be forgiven or paid - off by year - end 2021 3) Stable loan rates 4) New security yields at lower rates Interest Expense Down $1.4 million (improvement) Cost of deposits declined by 4 basis points. Cost of deposits decreased 64 basis points from 12/31/19 to 3/31/21. Anticipate slight additional decline in Q221. Net Interest Income Down $8.3 million We expect loans rates to be stable and deposit rates to decline slightly, but NIM will be effective by PPP forgiveness and liquidity. Trust Revenue Up $0.1 million Anticipate flat Trust revenue for Q2 and Q3, until our new staff is onboard and productive. Service Charges Down $1.1 million Decrease was primarily due to first quarter seasonality and the impact from the stimulus payments. We expect the stimulus to lead to further reductions in services charges in Q2 21. We are providing relief on some overdraft fees. Mortgage Revenue Up $3.5 million In Q4 20, Mortgage loan volume decline which resulted in lower revenue and a decrease in the fair value mandatory delivery adjustment. We expect mortgage volume to decline throughout 2021. We expect home purchase volume to be steady, but refinance volume to decline. Debit and Credit Card fees Up $0.3 million Credit card revenue was up slightly from Q420. Anticipate modest increase for the balance of 2021. Gain on Sale of Securities Up $5.5 million Sold securities with a gain of $5.3 million Management will continue to look for opportunities to maximize the value of the investment portfolio. Other income Down $0.3 million Gain on sale of Illinois branches of $5.5 million in Q1 21. Decrease from Q4 20 of approximant $5.8 million, primarily attributable to 2020 year - end adjustments in CRA related SBIC investment funds. Management expects other income to more closely track historical trends for the balance of 2021. Revenue 25

Category Q1 - 21 Linked Quarter Change Management’s Outlook Provision Expense Down $5.5 million Provision expense was lower in Q1 21 due to an improvement in Moody’s Economic Scenario Forecast, decline in loan portfolio and a decline in non - performing loans. The $1.4 million in provision expense is made up of the following: 1. Provision for loan losses $0 2. Provision for security portfolio losses $1.4 million (CECL adjustment on bond purchases in Q1) We expect lower provisioning in 2021, subject to the following: 1. Loan Growth – expect mid single digit growth in the second half of 2021 2. Charge - offs – if not specifically reserved 3. Moody’s Economic Scenario Forecast: Management’s weighting for Q1: • Moody’s S1: 20% • Moody’s Baseline: 70% • Moody’s S2: 10% Salaries and Employee Benefits up $4.6 million Primarily driven by a $2.4 million increase in payroll tax/401k expense and a $2.2 million increase in incentive plan accruals (Q4 20 included true - up reversals of accruals). We might see some increases throughout the year as we are hiring in lending, wealth and mortgage. Occupancy Expense Up $0.1 million Expect occupancy expense for the balance of 2021 to be flat to slightly down. Other operating Expense Down $17.5 million Non - core – down $10.7 million related to branch rightsizing. Core – down $6.7 million, primarily due to the $3 million special contribution to the Simmons First Foundation in Q4 20. Enhanced emphasis on efficiencies throughout the Company. We will continue to invest in our digital capacity. Non - interest Expense $115.4 Million, down $12.8 million Non - core – $0.9 million, down $11.6 million related to branch rightsizing and other non - core items. Core – $114.5 million, down $1.1 million. Anticipate quarterly run - rate of approximately $112 - $115 million for the balance of 2021. Provision and Non - interest Expense 26
