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 Q4 - 20 Linked Quarter Change Management’s Outlook Interest Income Down $0.6 million Primarily driven by lower loan volume, which was mostly offset by a $900 million increase in the security portfolio. Management anticipates the following for 2021: 1) Organic loan growth in the mid single digits 2) PPP balances to be forgiven or paid - off by year - end 2021 3) Security portfolio balance to be $5 billion by year - end 2021 4) Stable loan rates 5) New security yields at lower rates Interest Expense Down $2.0 million Cost of deposits declined by 5 basis points, primarily driven by time deposit repricing. Cost of deposits decreased 60 basis points from 12/31/19 to 12/31/20. Anticipate slight additional decline in Q121. Net Interest Income Up $1.4 million Driven by lower cost of deposits. Expect a slightly improving net interest income and NIM for Q121, as PPP loans are forgiven and the expected increase in the security portfolio. Trust Revenue Down $0.2 million Anticipate flat Trust revenue for the first three quarters, until our new staff is onboard and productive. Service Charges Up $0.4 million Increase was primarily due to fourth quarter seasonal increase. We expect the stimulus to lead to a reduction in services charges and we are providing relief to some overdraft fees. Mortgage Revenue Down $11.0 million Mortgage loan volume declined in Q4, which resulted in lower revenue and a decrease in the fair value mandatory delivery adjustment. We would expect mortgage volume to decline throughout 2021. Debit and Credit Card fees Down $0.1 million Merchant revenue down slightly from Q320. Anticipate modest increase for 2021. Gain on Sale of Securities Down $22.3 million No securities sold in Q420. Management will continue to look for opportunities to maximize the value of the investment portfolio. Other income Up $5.2 million Increase was primarily attributable to year - end adjustments in CRA related SBIC investment funds. Management expects other income to more closely track historical trends in 2021. Revenue 22

Category Q4 - 20 Linked Quarter Change Management’s Outlook Provision Expense Down $16.0 million Provision expense was lower in Q420 due to an improvement in Moody’s Economic Scenario Forecast, decline in loan portfolio and a decline in non - performing loans. We expect lower provisioning in 2021, subject to the following: 1. Loan Growth – expect mid single digit growth 2. Charge - off’s – if not specifically reserved 3. Moody’s Economic Scenario Forecast: Management’s weighting for Q4: • Moody’s S1: 17% • Moody’s Baseline: 68% • Moody’s S2: 15% Salaries and Employee Benefits Down $5.4 million Non - core – down $3.2 million from Q320 related to branch rightsizing and other non - core items. Core – down $2.3 million, impact from efficiency initiatives and year - end accrual adjustments. Expect increase in Q121 due to first quarter timing of payroll taxes and 401k expense. Occupancy Expense Down $0.5 million Non - core – up $0.7 million related to branch rightsizing and other non - core items. Core – down $1.2 million, impact from efficiency initiatives. Expect occupancy expense for 2021 to be down as a result of the branch rightsizing initiative in 2020. Other operating Expense Up $15.0 million Non - core – up $10.3 million related to branch rightsizing. Core – up $4.7 million, due to the special $3 million contribution to the Simmons First Foundation and timing differences in legal, audit and marketing expenses. Enhanced emphasis on efficiencies throughout the Company. We will continue to invest in our digital capacity. Non - interest Expense $128.1 Million, up $9.2 million Non - core – $12.5 million, up $8.8 million related to branch rightsizing and other non - core items. Core – $115.6 million, up $0.4 million. Anticipate quarterly run - rate of approximately $114 - $116 million in Q1 and $112 - $115 million for each other quarter in 2021. Provision and Non - interest Expense 23
