CORPORATION CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 1: PREPARATION OF INTERIM FINANCIAL STATEMENTS Description of Business and Organizational Structure Simmons First National Corporation (“Company”) is a Mid-South financial holding company headquartered in Pine Bluff, Arkansas, and the parent company of Simmons Bank, an Arkansas state-chartered bank that has been in operation since 1903 (“Simmons Bank” or the “Bank”). Simmons First Insurance Services, Inc. and Simmons First Insurance Services of TN, LLC are wholly-owned subsidiaries of Simmons Bank and are insurance agencies that offer various lines of personal and corporate insurance coverage to individual and commercial customers. The Company, through its subsidiaries, offers, among other things, consumer, real estate and commercial loans; checking, savings and time deposits; and specialized products and services (such as credit cards, trust and fiduciary services, investments, agricultural finance lending, equipment lending, insurance and Small Business Administration (“SBA”) lending) from approximately 220 financial centers as of June 30, 2026, located throughout market areas in Arkansas, Kansas, Missouri, Oklahoma, Tennessee and Texas. Basis of Presentation The accompanying unaudited consolidated financial statements have been prepared based upon Securities and Exchange Commission (“SEC”) rules that permit reduced disclosures for interim periods. Certain information and footnote disclosures have been condensed or omitted in accordance with those rules and regulations. The accompanying consolidated balance sheet as of December 31, 2025, was derived from audited financial statements. In the opinion of management, these financial statements reflect all adjustments that are necessary for a fair presentation of interim results of operations, including normal recurring accruals. Significant intercompany accounts and transactions have been eliminated in consolidation. The results for the interim periods are not necessarily indicative of results for the full year. For a more complete discussion of significant accounting policies and certain other information, this report should be read in conjunction with the consolidated financial statements and accompanying notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025, which was filed with the SEC on February 25, 2026. The preparation of financial statements, in accordance with accounting principles generally accepted in the United States (“US GAAP”), requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, income items and expenses and disclosure of contingent assets and liabilities. The estimates and assumptions used in the accompanying consolidated financial statements are based upon management’s evaluation of the relevant facts and circumstances as of the date of the consolidated financial statements and actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change relate to the determination of the allowance for credit losses, valuation of goodwill and subsequent impairment analysis and income taxes. Management obtains third party valuations to assist in valuing certain aspects of these material estimates, as appropriate, including independent appraisals for significant properties in connection with the determination of the allowance for credit losses. Assumptions used in the goodwill impairment analysis involve internally projected forecasts, coupled with market and third-party data. These material estimates could change as a result of the uncertainty in current macroeconomic conditions and other factors that are beyond the Company’s control and could cause actual results to differ materially from those projected. 9 Recently Issued Accounting Standards Interim Reporting - In December 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”), that clarifies and enhances guidance on interim financial reporting by (i) clarifying the scope such that it now explicitly applies only to entities that issue complete interim financial statements and related notes under U.S. GAAP, (ii) establishes clear guidance on the form of interim statements and notes, incorporating a comprehensive list of required interim disclosures and (iii) introduces a requirement to disclose material events and changes occurring after the end of the last annual period that could impact interim results. ASU 2025-11 is effective for interim reporting periods with annual reporting periods beginning after December 15, 2027, with early adoption permitted. The adoption of ASU 2025-11 is not expected to have a material impact on the Company’s operations, financial position or disclosures. Derivatives and Hedging - In November 2025, the FASB issued ASU No. 2025-09, Derivatives and Hedging (Topic 815): Hedge Accounting Improvements (“ASU 2025-09”), that targets to align hedge accounting more closely with an entity’s economic risk management practices. ASU 2025-09 addresses improvements for five specific issues: (i) similar risk assessment for cash flow hedges, (ii) hedging interest payments on choose-your-rate debt, (iii) cash flow hedges of nonfinancial forecasted transactions, (iv) net written options as hedging instruments and (v) foreign currency-denominated debt designated as a hedging instrument and a hedged item. ASU 2025-09 is effective for fiscal years beginning after December 15, 2026, and interim periods within those fiscal years and is not expected to have a material impact on the Company’s operations, financial position or disclosures. Purchased Loans - In November 2025, the FASB issued ASU No. 2025-08, Financial Instruments-Credit Losses (Topic 326): Purchased Loans (“ASU 2025-08”), that expands the scope of the “gross-up” method, formerly applicable only to PCD assets, to include acquired non-PCD loans that meet certain criteria, now referred to as purchased seasoned loans (“PSLs”). Under this model, an allowance for expected credit losses is recognized at acquisition, offsetting the loan’s amortized cost basis, thereby eliminating the day-one credit loss expense previously required for non-PCD assets. PSLs are defined as non-PCD loans acquired either (i) through a business combination or (ii) purchased more than 90 days after origination when the acquirer was not involved in origination. ASU 2025-08 will be effective for the Company, on a prospective basis for loans acquired on or after the adoption date, for interim and annual reporting periods beginning in 2027, though early adoption is permitted. The adoption of ASU 2025-08 is not expected to have a material impact on the Company’s operations, financial position or disclosures. Disaggregation of Income Statement Expenses - In November 2024, the FASB issued ASU No. 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), that requires footnote disclosure about specific expenses by requiring companies to disaggregate, in a tabular presentation, each relevant expense caption on the face of the income statement that includes any of the following natural expenses: (i) purchases of inventory, (ii) employee compensation, (iii) depreciation, (iv) intangible asset amortization and (v) depreciation, depletion and amortization recognized as part of oil- and gas-producing activities. The tabular disclosure would also include certain other expenses, when applicable. ASU 2024-03 does not change or remove existing expense disclosure requirements; however, it may affect where that information appears in the footnotes to the financial statements. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The adoption of ASU 2024-03 is not expected to have a material impact on the Company’s operations, financial position or disclosures. There have been no other significant changes to the Company’s accounting policies disclosed in Note 1, Summary of Significant Accounting Policies, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Presently, the Company is not aware of any other changes to the Accounting Standards Codification that will have a material impact on its present or future financial position or results of operations. 10 NOTE 2: INVESTMENT SECURITIES Held-to-maturity (“HTM”) securities, which include any security for which the Company has both the positive intent and ability to hold until maturity, are carried at historical cost adjusted for amortization of premiums and accretion of discounts. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant effective yield method over the security’s estimated life. Prepayments are anticipated for mortgage-backed and SBA securities. Premiums on callable securities are amortized to their earliest call date. Available-for-sale (“AFS”) securities, which include any security for which the Company has no immediate plan to sell but which may be sold in the future, are carried at fair value. Realized gains and losses, based on specifically identified amortized cost of the individual security, are included in other income. Unrealized gains and losses are recorded, net of related income tax effects, in stockholders’ equity, further discussed below. Premiums and discounts are amortized and accreted, respectively, to interest income using the constant effective yield method over the estimated life of the security. Prepayments are anticipated for mortgage-backed and SBA securities. Premiums on callable securities are amortized to their earliest call date. Assets held in trading accounts, comprised of U.S. Treasury securities, are purchased with the intent of selling in the near term. Trading securities are carried at fair value with gains and losses included in other income. During the third quarter of 2025, the Company and its subsidiaries initiated and completed steps taken to reposition the Company’s consolidated balance sheet and reclassified approximately $3.59 billion in HTM investment securities to AFS investment securities. Subsequently, the Company sold approximately $3.16 billion in amortized cost basis of AFS securities (including certain of those previously classified as HTM). The sale of investment securities resulted in a realized, after-tax ordinary loss of $625.6 million (based on actual tax rate of 21.946%). During the quarters ended June 30, 2022 and September 30, 2021, the Company transferred, at fair value, $1.99 billion and $500.8 million, respectively, of securities from the AFS portfolio to the HTM portfolio. No gains or losses on these securities were recognized at the time of transfer. During the balance sheet repositioning that occurred during 2025, the remaining securities were transferred out of the HTM portfolio to the AFS portfolio at fair value and either subsequently sold or maintained within the AFS portfolio. As a result of the balance sheet repositioning, the Company did not hold any investment securities classified as HTM as of June 30, 2026 or December 31, 2025. The amortized cost, fair value and allowance for credit losses of investment securities that are classified as AFS are as follows: (In thousands) Amortized Cost Allowance for Credit Losses Gross Unrealized Gains Gross Unrealized (Losses) Estimated Fair Value Available-for-sale June 30, 2026 U.S. Government agencies $ 45,008 $ — $ 4 $ (587) $ 44,425 Mortgage-backed securities 2,254,293 — 665 (193,198) 2,061,760 State and political subdivisions 1,030,971 — 32 (165,536) 865,467 Other securities 109,254 — 3 (3,728) 105,529 Total AFS $ 3,439,526 $ — $ 704 $ (363,049) $ 3,077,181 December 31, 2025 U.S. Government agencies $ 47,786 $ — $ 6 $ (620) $ 47,172 Mortgage-backed securities 2,385,646 — 6,072 (189,760) 2,201,958 State and political subdivisions 1,046,121 — 42 (187,092) 859,071 Other securities 163,256 — 209 (5,445) 158,020 Total AFS $ 3,642,809 $ — $ 6,329 $ (382,917) $ 3,266,221 As of June 30, 2026, AFS MBS consisted of $562.5 million and $1.50 billion of commercial MBS and residential MBS, respectively. As of December 31, 2025, AFS MBS consisted of $597.4 million and $1.60 billion of commercial MBS and residential MBS, respectively. 11 Accrued interest receivable on AFS securities at June 30, 2026 was $21.6 million, and is included in interest receivable on the consolidated balance sheet. The Company has made the election to exclude all accrued interest receivable from securities from the estimate of credit losses. The following table summarizes the Company’s AFS investments in an unrealized loss position for which an allowance for credit loss has not been recorded as of June 30, 2026 and December 31, 2025, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position: Less Than 12 Months 12 Months or More Total (In thousands) Estimated Fair Value Gross Unrealized Losses Estimated Fair Value Gross Unrealized Losses Estimated Fair Value Gross Unrealized Losses Available-for-sale June 30, 2026 U.S. Government agencies $ — $ — $ 43,291 $ (587) $ 43,291 $ (587) Mortgage-backed securities 210,440 (871) 1,559,771 (192,327) 1,770,211 (193,198) State and political subdivisions 7,227 (14) 835,710 (165,522) 842,937 (165,536) Other securities 9,936 (16) 81,411 (3,712) 91,347 (3,728) Total AFS $ 227,603 $ (901) $ 2,520,183 $ (362,148) $ 2,747,786 $ (363,049) December 31, 2025 U.S. Government agencies $ 2,247 $ (17) $ 43,767 $ (603) $ 46,014 $ (620) Mortgage-backed securities 15,305 (74) 1,672,723 (189,686) 1,688,028 (189,760) State and political subdivisions 5,757 (969) 824,265 (186,123) 830,022 (187,092) Other securities — — 96,176 (5,445) 96,176 (5,445) Total AFS $ 23,309 $ (1,060) $ 2,636,931 $ (381,857) $ 2,660,240 $ (382,917) As of June 30, 2026, the Company’s investment portfolio included $3.08 billion of AFS securities, of which $2.75 billion, or 89.3%, were in an unrealized loss position that were not deemed to have credit losses. A portion of the unrealized losses were related to the Company’s MBS, which are issued and guaranteed by U.S. government-sponsored entities and agencies, and the Company’s state and political subdivision securities, specifically investments in insured fixed rate municipal bonds for which the issuers continue to make timely principal and interest payments under the contractual terms of the securities. Furthermore, the decline in fair value for each of the above AFS securities is attributable to the rates for those investments yielding less than current market rates. Management does not believe any of the securities are impaired due to reasons of credit quality. Management believes the declines in fair value for the securities are temporary. Management does not have the immediate intent to sell the securities, and management believes the accounting standard of “more likely than not” has not been met regarding whether the Company would be required to sell any of the AFS securities before recovery of amortized cost. Allowance for Credit Losses All MBS held by the Company are issued by U.S. government-sponsored entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, highly rated by major rating agencies and have a long history of no credit losses. Accordingly, no allowance for credit losses has been recorded for these securities. Regarding securities issued by state and political subdivisions and other HTM securities, the adequacy of the reserve for credit loss is determined quarterly based on methodology similar to the methodology for determining the allowance for credit losses on loans. The methodology considers, but is not limited to: (i) issuer bond ratings, (ii) issuer geography, (iii) whether issuers continue to make timely principal and interest payments under the contractual terms of the securities, (iv) probability-weighted multiple scenario forecasts, and (v) the issuers’ size. 12 As a result of the balance sheet repositioning, the Company did not hold any investment securities classified as HTM as of June 30, 2026. Activity in the allowance for credit losses by investment security type for the three and six months ended June 30, 2025 on the Company’s HTM securities portfolio was as follows: (In thousands) State and Political Subdivisions Other Securities Total Three Months Ended June 30, 2025 Held-to-maturity Beginning balance, April 1, 2025 $ 171 $ 3,043 $ 3,214 Provision for credit loss expense — — — Net increase (decrease) in allowance on previously impaired securities 31 (31) — Ending balance, June 30, 2025 $ 202 $ 3,012 $ 3,214 Six Months Ended June 30, 2025 Held-to-maturity Beginning balance, January 1, 2025 $ 196 $ 3,018 $ 3,214 Provision for credit loss expense — — — Net increase (decrease) in allowance on previously impaired securities 6 (6) — Ending balance, June 30, 2025 $ 202 $ 3,012 $ 3,214 Based upon the Company’s analysis of the underlying risk characteristics of its AFS portfolio, including credit ratings and other qualitative factors, as previously discussed, there was no provision for credit losses related to the Company’s AFS portfolio recorded for the three and six month periods ended June 30, 2026 or 2025. Income earned on securities for the three and six months ended June 30, 2026 and 2025, is as follows: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2026 2025 2026 2025 Taxable: Held-to-maturity $ — $ 10,224 $ — $ 20,623 Available-for-sale 25,472 21,009 51,783 42,194 Non-taxable: Held-to-maturity — 10,052 — 20,103 Available-for-sale 5,541 5,613 11,112 11,235 Total $ 31,013 $ 46,898 $ 62,895 $ 94,155 The amortized cost and estimated fair value by maturity of AFS securities as of June 30, 2026 are shown in the following table. Securities are classified according to their contractual maturities without consideration of principal amortization, potential prepayments or call options. Accordingly, actual maturities may differ from contractual maturities.

There were no gross realized gains and no gross realized losses from the call or sale of securities during the three and six months ended June 30, 2026 and 2025, as they were recognized at book value of the security. The Company has entered into various hedging transactions to help mitigate the impact of changing interest rates on the fair value of AFS securities. See Note 22, Derivative Instruments, for disclosure of the gains and losses recognized on derivative instruments and the cumulative fair value hedging adjustments to the carrying amount of the hedged securities. NOTE 3: LOANS AND ALLOWANCE FOR CREDIT LOSSES At June 30, 2026, the Company’s loan portfolio was $18.06 billion, compared to $17.49 billion at December 31, 2025. The various categories of loans are summarized as follows: June 30, December 31, (In thousands) 2026 2025 Consumer: Credit cards $ 174,148 $ 175,760 Other consumer 99,117 115,472 Total consumer 273,265 291,232 Real Estate: Construction and development 2,577,630 2,873,807 Single family residential 2,564,282 2,607,450 Other commercial 8,828,771 8,289,968 Total real estate 13,970,683 13,771,225 Commercial: Commercial 2,516,607 2,382,339 Agricultural 426,522 306,300 Total commercial 2,943,129 2,688,639 Other 875,292 741,083 Total loans $ 18,062,369 $ 17,492,179 The above table presents total loans at amortized cost. The difference between amortized cost and unpaid principal balance is due to (i) premiums and discounts associated with acquisition date fair value adjustments on acquired loans of $1.7 million and $3.3 million at June 30, 2026 and December 31, 2025, respectively, and (ii) deferred origination costs and fees of $3.8 million and $5.4 million at June 30, 2026 and December 31, 2025, respectively. Accrued interest on loans, which is excluded from the amortized cost of loans held for investment, totaled $81.4 million and $80.3 million at June 30, 2026 and December 31, 2025, respectively, and is included in interest receivable on the consolidated balance sheets. Loan Origination/Risk Management – The Company seeks to manage its credit risk by diversifying its loan portfolio, determining that borrowers have adequate sources of cash flow for loan repayment without liquidation of collateral; obtaining and monitoring collateral; and providing an adequate allowance for credit losses by regularly reviewing loans through the internal loan review process. The loan portfolio is diversified by borrower, purpose and industry. The Company seeks to use diversification within the loan portfolio to reduce its credit risk, thereby minimizing the adverse impact on the portfolio if weaknesses develop in either the economy or a particular segment of borrowers. Collateral requirements are based on credit assessments of borrowers and may be used to recover the debt in case of default. Consumer – The consumer loan portfolio consists of credit card loans and other consumer loans. Credit card loans are diversified by geographic region to reduce credit risk and minimize any adverse impact on the portfolio. Although they are regularly reviewed to facilitate the identification and monitoring of creditworthiness, credit card loans are unsecured loans, making them more susceptible to economic downturns that result in increased unemployment. Other consumer loans include direct installment loans and account overdrafts. Loans in this portfolio segment are sensitive to unemployment and other key consumer economic measures. 14 Real estate – The real estate loan portfolio consists of construction and development loans (“C&D”), single family residential loans and commercial loans. C&D and commercial real estate (“CRE”) loans can be particularly sensitive to valuation of real estate. CRE cycles are inevitable. The long planning and production process for new properties and rapid shifts in business conditions and employment create an inherent tension between supply and demand for commercial properties. While general economic trends often move individual markets in the same direction over time, the timing and magnitude of changes are determined by other forces unique to each market. CRE cycles tend to be local in nature and longer than other credit cycles. Factors influencing the CRE market are traditionally different from those affecting residential real estate markets; thereby making predictions for one market based on the other difficult. Additionally, submarkets within CRE – such as office, industrial, apartment, retail and hotel – also experience different cycles, providing an opportunity to lower the overall risk through diversification across types of CRE loans. Management realizes that local demand and supply conditions will also mean that different geographic areas will experience cycles of different amplitude and duration. The Company monitors these loans closely. Commercial – The commercial loan portfolio includes commercial and agricultural loans, representing loans to commercial customers and farmers for use in normal business or farming operations to finance working capital needs, equipment purchases or other expansion projects. Collection risk in this portfolio is driven by the creditworthiness of the underlying borrowers, particularly cash flow from customers’ business or farming operations. The Company continues its efforts to keep loan terms short, reducing the negative impact of upward movement in interest rates. Term loans are generally set up with one or three year balloons, and the Company has instituted a pricing mechanism for commercial loans. It is general practice to require personal guaranties on commercial loans for closely-held or limited liability entities. Other – The other loan portfolio includes mortgage warehouse loans, representing warehouse lines of credit to mortgage originators for the disbursement of newly originated 1-4 family residential loans. Also included in the other loan portfolio are loans to public sector customers, including state and local governments. Nonaccrual and Past Due Loans – Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory provisions. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income is subsequently recognized only to the extent cash payments are received in excess of principal due. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured. The amortized cost basis of nonaccrual loans segregated by class of loans are as follows: June 30, December 31, (In thousands) 2026 2025 Consumer: Credit cards $ 499 $ 568 Other consumer 196 386 Total consumer 695 954 Real estate: Construction and development 55,536 17,516 Single family residential 43,534 33,345 Other commercial 46,033 45,417 Total real estate 145,103 96,278 Commercial: Commercial 19,172 13,458 Agricultural 325 1,098 Total commercial 19,497 14,556 Other — 3 Total $ 165,295 $ 111,791 As of June 30, 2026 and December 31, 2025, nonaccrual loans for which there was no related allowance for credit losses had an amortized cost of $23.3 million and $18.0 million, respectively. These loans are individually assessed and do not hold an allowance due to being adequately collateralized under the collateral-dependent valuation method. 15 An age analysis of the amortized cost basis of past due loans, including nonaccrual loans, segregated by class of loans is as follows: (In thousands) Gross 30-89 Days Past Due 90 Days or More Past Due Total Past Due Current Total Loans 90 Days Past Due & Accruing June 30, 2026 Consumer: Credit cards $ 2,973 $ 701 $ 3,674 $ 170,474 $ 174,148 $ 610 Other consumer 655 121 776 98,341 99,117 — Total consumer 3,628 822 4,450 268,815 273,265 610 Real estate: Construction and development 106 54,747 54,853 2,522,777 2,577,630 — Single family residential 17,133 22,083 39,216 2,525,066 2,564,282 — Other commercial 36,510 44,429 80,939 8,747,832 8,828,771 143 Total real estate 53,749 121,259 175,008 13,795,675 13,970,683 143 Commercial: Commercial 2,989 12,563 15,552 2,501,055 2,516,607 — Agricultural 34 292 326 426,196 426,522 — Total commercial 3,023 12,855 15,878 2,927,251 2,943,129 — Other 588 — 588 874,704 875,292 — Total $ 60,988 $ 134,936 $ 195,924 $ 17,866,445 $ 18,062,369 $ 753 December 31, 2025 Consumer: Credit cards $ 2,414 $ 751 $ 3,165 $ 172,595 $ 175,760 $ 697 Other consumer 1,073 166 1,239 114,233 115,472 — Total consumer 3,487 917 4,404 286,828 291,232 697 Real estate: Construction and development 13,344 17,418 30,762 2,843,045 2,873,807 — Single family residential 34,731 15,690 50,421 2,557,029 2,607,450 — Other commercial 10,879 38,047 48,926 8,241,042 8,289,968 148 Total real estate 58,954 71,155 130,109 13,641,116 13,771,225 148 Commercial: Commercial 2,755 10,672 13,427 2,368,912 2,382,339 103 Agricultural 14 598 612 305,688 306,300 — Total commercial 2,769 11,270 14,039 2,674,600 2,688,639 103 Other — 3 3 741,080 741,083 — Total $ 65,210 $ 83,345 $ 148,555 $ 17,343,624 $ 17,492,179 $ 948 Loan Modifications to Borrowers Experiencing Financial Difficulty The Company has internal loan modification programs for borrowers experiencing financial difficulties. Modifications to borrowers experiencing financial difficulties may include interest rate reductions, principal or interest forgiveness and/or term extensions. The Company primarily uses interest rate reduction and/or payment modifications or extensions, with an occasional forgiveness of principal. 16 The following table presents a summary of the amortized cost basis of loan modifications granted to borrowers experiencing financial difficulty, segregated by class of loans and type of loan modification, for the three and six month periods ended June 30, 2026.

Furthermore, such modifications did not significantly impact the Company’s determination of the allowance for credit losses during the period. The following table presents a summary of the amortized cost basis of loan modifications granted to borrowers experiencing financial difficulty, segregated by class of loans and type of loan modification, for the three and six month periods ended June 30, 2025.

Furthermore, such modifications did not significantly impact the Company’s determination of the allowance for credit losses during those periods. 17 The Company closely monitors the performance of loans that are modified to borrowers experiencing financial difficulty. During the six months ended June 30, 2026, there were no loans to borrowers experiencing financial difficulty (modified in the previous twelve months) that had a payment default during the period. There was one CRE loan, related to a downtown St. Louis hotel that was originated pre-pandemic, to a borrower experiencing financial difficulty with a period-end amortized cost basis of $26.7 million that was modified during 2024 which subsequently defaulted during the six months ended June 30, 2025. This CRE loan was placed on nonaccrual status and ultimately charged off during 2025. In relation to loans modified to borrowers experiencing financial difficulty, the Company defines a payment default as a payment received more than 90 days after its due date. At June 30, 2026 and December 31, 2025, the Company had $3.9 million and $4.4 million, respectively, of consumer mortgage loans secured by residential real estate properties for which formal foreclosure proceedings are in process. At June 30, 2026 and December 31, 2025, the Company had $3.1 million and $3.6 million, respectively, of Other Real Estate Owned (“OREO”) secured by residential real estate properties. Credit Quality Indicators – As part of the on-going monitoring of the credit quality of the Company’s loan portfolio, management tracks certain credit quality indicators including trends related to (i) the weighted-average risk rating of commercial and real estate loans, (ii) the level of classified commercial and real estate loans, (iii) net charge-offs, (iv) nonperforming loans (see details above) and (v) the general economic conditions of the Company’s local markets. The Company utilizes a risk rating matrix to assign a risk rate to each of its commercial and real estate loans. Risk ratings are updated on an ongoing basis and are subject to change by continuous loan monitoring processes including lending management monitoring, executive management and board committee oversight, and independent credit review. A description of the general characteristics of the risk ratings is as follows: •Pass (Excellent) – This category includes loans which are virtually free of credit risk. Borrowers in this category represent the highest credit quality and greatest financial strength. •Pass (Good) - Loans under this category possess a nominal risk of default. This category includes borrowers with strong financial strength and superior financial ratios and trends. These loans are generally fully secured by cash or equivalents (other than those rated “excellent”). •Pass (Acceptable – Average) - Loans in this category are considered to possess a normal level of risk. Borrowers in this category have satisfactory financial strength and adequate cash flow coverage to service debt requirements. If secured, the perfected collateral should be of acceptable quality and within established borrowing parameters. •Pass (Monitor) - Loans in the Watch (Monitor) category exhibit an overall acceptable level of risk, but that risk may be increased by certain conditions, which represent “red flags”. These “red flags” require a higher level of supervision or monitoring than the normal “Pass” rated credit. The borrower may be experiencing these conditions for the first time, or it may be recovering from weakness, which at one time justified a higher rating. These conditions may include: weaknesses in financial trends; marginal cash flow; one-time negative operating results; non-compliance with policy or borrowing agreements; poor diversity in operations; lack of adequate monitoring information or lender supervision; questionable management ability/stability. •Special Mention - A loan in this category has potential weaknesses that deserve management’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special Mention loans are not adversely classified (although they are “criticized”) and do not expose an institution to sufficient risk to warrant adverse classification. Borrowers may be experiencing adverse operating trends or an ill-proportioned balance sheet. Non-financial characteristics of a Special Mention rating may include management problems, pending litigation, a non-existent or ineffective loan agreement or other material structural weakness, and/or other significant deviation from prudent lending practices. •Substandard - A Substandard loan is inadequately protected by the current sound worth and paying capacity of the borrower or of the collateral pledged, if any. Loans so classified must have a well-defined weakness, or weaknesses, that jeopardize the liquidation of the debt. The loans are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected. This does not imply ultimate loss of the principal, but may involve burdensome administrative expenses and the accompanying cost to carry the loan. 18 •Doubtful - A loan classified Doubtful has all the weaknesses inherent in a substandard loan except that the weaknesses make collection or liquidation in full (on the basis of currently existing facts, conditions, and values) highly questionable and improbable. Doubtful borrowers are usually in default, lack adequate liquidity or capital, and lack the resources necessary to remain an operating entity. The possibility of loss is extremely high, but because of specific pending events that may strengthen the asset, its classification as loss is deferred. Pending factors include: proposed merger or acquisition; liquidation procedures; capital injection; perfection of liens on additional collateral; and refinancing plans. Loans classified as Doubtful are placed on nonaccrual status. •Loss - Loans classified Loss are considered uncollectible and of such little value that their continuance as bankable assets is not warranted. This classification does not mean that the loans has absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off this basically worthless loan, even though partial recovery may be affected in the future. Borrowers in the Loss category are often in bankruptcy, have formally suspended debt repayments, or have otherwise ceased normal business operations. Loans should be classified as Loss and charged-off in the period in which they become uncollectible. The Company monitors credit quality in the consumer portfolio by delinquency status. The delinquency status of loans is updated daily. A description of the delinquency credit quality indicators is as follows: •Current - Loans in this category are either current in payments or are under 30 days past due. These loans are considered to have a normal level of risk. •30-89 Days Past Due - Loans in this category are between 30 and 89 days past due and are subject to the Company’s loss mitigation process. These loans are considered to have a moderate level of risk. •90+ Days Past Due - Loans in this category are 90 days or more past due and are placed on nonaccrual status. These loans have been subject to the Company’s loss mitigation process and foreclosure and/or charge-off proceedings have commenced. The Company uses a dual risk rating scale that utilizes quantitative models and qualitative factors (“score cards”) to assist in determining the appropriate risk rating for its commercial loans. This dual risk rating methodology incorporates a “probability of default” analysis which utilizes quantified metrics such as loan terms and financial performance, as well as a “loss given default” analysis which utilizes collateral values and economics of the market, among other attributes. Model outputs are reviewed and analyzed to ensure the projected risk levels are commensurate with underwriting and credit leader expectations. The risk rating scale includes Probability of Default levels of 1 – 16 and Loss Given Default levels of A – I. The scale allows for more granular recognition of risk and diversification of grading among traditional Pass grades. The following is a reconciliation between the expanded risk rating scale and the Company’s traditional risk rating segments utilized within the commercial loan classes presented in the credit quality indicator tables. •Pass - Includes loans with an expanded risk rating of 1 through 11. Loans with a risk rating of 10 and 11 equate to loans included on management’s “watch list” and is intended to be utilized on a temporary basis for pass grade borrowers where a significant risk-modifying action is anticipated in the near term. •Special Mention - Includes loans with an expanded risk rating of 12. •Substandard - Includes loans with an expanded risk rating of 13 and 14. •Doubtful and loss - Includes loans with an expanded risk rating of 15 and 16. 19 The following table presents a summary of loans by credit quality indicator, as of June 30, 2026, segregated by class of loans.

The allowance, in the judgment of management, is necessary to reserve for expected loan losses and risks inherent in the loan portfolio. The Company’s allowance for credit loss methodology includes reserve factors calculated to estimate current expected credit losses to amortized cost balances over the remaining contractual life of the portfolio, adjusted for prepayments, in accordance with ASC Topic 326-20, Financial Instruments - Credit Losses. Accordingly, the methodology is comprised of two components: individual assessments on loans with unique risk characteristics and collective assessments for loans that share similar risk characteristics. Loans with similar risk characteristics such as loan type, collateral type, and internal risk ratings are aggregated for collective assessment. The Company uses statistically-based models that leverage assumptions about current and future economic conditions throughout the contractual life of the loan. Expected credit losses are estimated by either lifetime loss rates or expected loss cash flows based on three key parameters: probability-of-default (“PD”), exposure-at-default (“EAD”), and loss-given-default (“LGD”). Future economic conditions are incorporated to the extent that they are reasonable and supportable. Beyond the reasonable and supportable periods, the economic variables revert to a historical equilibrium at a pace dependent on the state of the economy reflected within the economic scenarios. To determine the best estimate of credit losses as of June 30, 2026, the Company utilized a probability-weighted, multiple-scenario approach consisting of Baseline, Upside (S1), and Downside (S3) scenarios published by Moody’s Analytics in June 2026 that was updated to reflect the U.S. economic outlook. The Company also includes qualitative adjustments to the allowance based on factors and considerations that have not otherwise been fully accounted for. These factors may include but are not limited to portfolio trends and considerations, other economic considerations, policy actions, concentration risk, or imprecision risk. 23 Loans with similar risk characteristics such as loan type, collateral type, and internal risk ratings are aggregated into homogeneous segments for assessment. Reserve factors are based on estimated probability of default and loss given default for each segment. The estimates are determined based on economic forecasts over the reasonable and supportable forecast period based on projected performance of economic variables that have a statistical relationship with the historical loss experience of the segments. Loans that have unique risk characteristics are evaluated on an individual basis. These evaluations are typically performed on loans with a deteriorated internal risk rating. For a collateral-dependent loan, the Company’s evaluation process includes a valuation by appraisal or other collateral analysis adjusted for selling costs, when appropriate. This valuation is compared to the remaining outstanding principal balance of the loan. If a loss is determined to be probable, the loss is included in the allowance for credit losses as a specific allocation. Loans for which the repayment is expected to be provided substantially through the operation or sale of collateral and where the borrower is experiencing financial difficulty had an amortized cost of $106.8 million and $112.4 million as of June 30, 2026 and December 31, 2025, respectively, as further detailed in the table below. The collateral securing these loans consist of commercial real estate properties, residential properties, and other business assets.

The provision for credit loss expense for the three and six months ended June 30, 2026 and 2025 reflected the impact of loan growth and updated economic assumptions during the periods, while the three and six months ended June 30, 2025 also included an incremental provision expense of $15.6 million related to two specific credit relationships which migrated to nonperforming during the period. Reserve for Unfunded Commitments In addition to the allowance for credit losses, the Company has established a reserve for unfunded commitments, classified in other liabilities. This reserve is maintained at a level management believes to be sufficient to absorb losses arising from unfunded loan commitments. The reserve for unfunded commitments was $25.6 million for both periods ended June 30, 2026 and December 31, 2025. The adequacy of the reserve for unfunded commitments is determined quarterly based on methodology similar to the methodology for determining the allowance for credit losses. No adjustment was made to the reserve for unfunded commitments during the three and six month periods ended June 30, 2026 or 2025, as it was considered sufficient to cover any loss expectations. 25 Provision for Credit Losses Provision for credit losses is determined by the Company as the amount to be added to the allowance for credit loss accounts for various types of financial instruments including loans, securities and off-balance-sheet credit exposure after net charge-offs have been deducted to bring the allowance to a level which, in management’s best estimate, is necessary to absorb expected credit losses over the lives of the respective financial instruments. The components of the provision for credit losses for the three and six month periods ended June 30, 2026 and 2025 were as follows: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2026 2025 2026 2025 Provision for credit losses related to: Loans $ 17,434 $ 11,945 $ 32,056 $ 38,742 Unfunded commitments — — — — Securities - HTM — — — — Securities - AFS — — — — Total $ 17,434 $ 11,945 $ 32,056 $ 38,742 NOTE 4: RIGHT-OF-USE LEASE ASSETS AND LEASE LIABILITIES The Company accounts for its leases in accordance with ASC Topic 842, Leases, which requires recognition of most leases, including operating leases, with a term greater than 12 months on the balance sheet. At lease commencement, the lease contract is reviewed to determine whether the contract is a finance lease or an operating lease; a lease liability is recognized on a discounted basis, related to the Company’s obligation to make lease payments; and a right-of-use asset is also recognized related to the Company’s right to use, or control the use of, a specified asset for the lease term. The Company accounts for lease and non-lease components (such as taxes, insurance and common area maintenance costs) separately as such amounts are generally readily determinable under the lease contracts. Lease payments over the expected term are discounted using the Company’s Federal Home Loan Bank (“FHLB”) advance rates for borrowings of similar term. If it is reasonably certain that a renewal or termination option will be exercised, the effects of such options are included in the determination of the expected lease term. Leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term. The Company’s leases are classified as operating leases with a term, including expected renewal or termination options, greater than one year, and are related to certain office facilities and office equipment. The following table presents information as of June 30, 2026 and December 31, 2025 related to the Company’s right-of-use lease assets, included in premises and equipment, and lease liabilities, included in accrued interest and other liabilities: June 30, December 31, (Dollars in thousands) 2026 2025 Right-of-use lease assets $ 37,332 $ 51,203 Lease liabilities 38,809 53,212 Weighted average remaining lease term 7.14 years 8.04 years Weighted average discount rate 3.98 % 4.18 % Operating lease cost for the three and six month periods ended June 30, 2026 was $6.8 million and $10.6 million, respectively, as compared to $3.8 million and $8.0 million for the same periods in 2025. 26 NOTE 5: PREMISES AND EQUIPMENT Premises and equipment are stated at cost less accumulated depreciation and amortization.

If the implied fair value of goodwill is lower than its carrying amount, goodwill impairment is indicated, and goodwill is written down to its implied fair value. Subsequent increases in goodwill value are not recognized in the financial statements. Goodwill totaled $1.32 billion at June 30, 2026 and December 31, 2025. Goodwill impairment was neither indicated nor recorded during the six months ended June 30, 2026 or the year ended December 31, 2025. Core deposit premiums represent the value of the relationships that acquired banks had with their deposit customers and are amortized over periods ranging from 10 years to 15 years and are periodically evaluated, at least annually, as to the recoverability of their carrying value. Other intangible assets represent the value of other acquired relationships, including relationships with trust and wealth management customers, and are being amortized over various periods ranging from 8 years to 15 years. Changes in the carrying amount and accumulated amortization of the Company’s core deposit premiums and other intangible assets at June 30, 2026 and December 31, 2025 were as follows: June 30, December 31, (In thousands) 2026 2025 Core deposit premiums: Balance, beginning of year $ 76,390 $ 87,575 Amortization (5,378) (11,185) Balance, end of period 71,012 76,390 Books of business and other intangibles: Balance, beginning of year 8,033 9,667 Amortization (817) (1,634) Balance, end of period 7,216 8,033 Total other intangible assets, net $ 78,228 $ 84,423 27 The carrying basis and accumulated amortization of the Company’s other intangible assets at June 30, 2026 and December 31, 2025 were as follows: June 30, December 31, (In thousands) 2026 2025 Core deposit premiums: Gross carrying amount $ 147,477 $ 173,305 Accumulated amortization (76,465) (96,915) Core deposit premiums, net 71,012 76,390 Books of business and other intangibles: Gross carrying amount 22,068 22,068 Accumulated amortization (14,852) (14,035) Books of business and other intangibles, net 7,216 8,033 Total other intangible assets, net $ 78,228 $ 84,423 The Company’s estimated remaining amortization expense on other intangible assets as of June 30, 2026 is as follows: (In thousands) Year Amortization Expense Remainder of 2026 $ 6,152 2027 12,218 2028 11,312 2029 8,563 2030 8,160 Thereafter 31,823 Total $ 78,228 NOTE 7: TIME DEPOSITS Time deposits included approximately $1.38 billion and $1.50 billion of certificates of deposit over $250,000 at June 30, 2026 and December 31, 2025, respectively.

Reg §1.263(a)-4 and amortized as ordinary deductions over the estimated life of the related loans. A reconciliation of income tax expense at the statutory rate to the Company’s actual income tax expense is shown for the periods indicated below: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2026 2025 2026 2025 Computed at the statutory rate (21%) $ 17,512 $ 13,365 $ 35,587 $ 21,387 Increase (decrease) in taxes resulting from: State income taxes, net of federal tax benefit 1,795 708 2,999 436 Discrete items related to share-based compensation (89) (64) 52 131 Tax exempt interest income (1,797) (3,809) (3,585) (7,617) Tax exempt earnings on BOLI (882) (754) (1,821) (1,550) Federal tax credits (493) (653) (1,038) (1,300) Other differences, net 656 78 2,034 3,196 Actual tax provision $ 16,702 $ 8,871 $ 34,228 $ 14,683 29 The Company follows ASC Topic 740, Income Taxes, which prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. Benefits from tax positions should be recognized in the financial statements only when it is more likely than not that the tax position will be sustained upon examination by the appropriate taxing authority that would have full knowledge of all relevant information. A tax position that meets the more-likely-than-not recognition threshold is measured at the largest amount of benefit that is greater than fifty percent likely of being realized upon ultimate settlement. Tax positions that previously failed to meet the more-likely-than-not recognition threshold should be recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more-likely-than-not recognition threshold should be derecognized in the first subsequent financial reporting period in which that threshold is no longer met. ASC Topic 740 also provides guidance on the accounting for and disclosure of unrecognized tax benefits, interest and penalties. The Company has no history of expiring net operating loss carryforwards and is projecting significant pre-tax and financial taxable income in future years. The Company expects to fully realize its deferred tax assets in the future. The amount of unrecognized tax benefits may increase or decrease in the future for various reasons including adding amounts for current tax year positions, expiration of open income tax returns due to the statutes of limitation, changes in management’s judgment about the level of uncertainty, status of examinations, litigation and legislative activity and the addition or elimination of uncertain tax positions. Section 382 of the Internal Revenue Code imposes an annual limit on the ability of a corporation that undergoes an “ownership change” to use its U.S. net operating losses to reduce its tax liability. The Company has engaged in three tax-free reorganization transactions in which acquired net operating losses are limited pursuant to Section 382. In total, approximately $24.9 million of federal net operating losses subject to the IRC Section 382 annual limitation are expected to be utilized by the Company. All of the acquired net operating loss carryforwards are expected to be fully utilized by 2036. The Company files income tax returns in the U.S. federal jurisdiction. The Company’s U.S. federal income tax returns are open and subject to examinations from the 2022 tax year and forward. The Company’s various state income tax returns are generally open from the 2022 and later tax return years based on individual state statute of limitations. NOTE 9: SECURITIES SOLD UNDER AGREEMENTS TO REPURCHASE The Company utilizes securities sold under agreements to repurchase to facilitate the needs of its customers and to facilitate secured short-term funding needs. Securities sold under agreements to repurchase are stated at the amount of cash received in connection with the transaction. The Company monitors collateral levels on a continuous basis. The Company may be required to provide additional collateral based on the fair value of the underlying securities. Securities pledged as collateral under repurchase agreements are maintained with the Company’s safekeeping agents. The gross amount of recognized liabilities for repurchase agreements was $6.2 million and $21.0 million at June 30, 2026 and December 31, 2025, respectively. The remaining contractual maturity of the securities sold under agreements to repurchase in the consolidated balance sheets as of June 30, 2026 and December 31, 2025 is presented in the following tables: Remaining Contractual Maturity of the Agreements (In thousands) Overnight and Continuous Up to 30 Days 30-90 Days Greater than 90 Days Total June 30, 2026 Repurchase agreements: U.S. Government agencies $ 6,216 $ — $ — $ — $ 6,216 December 31, 2025 Repurchase agreements: U.S. Government agencies $ 20,983 $ — $ — $ — $ 20,983 30 NOTE 10: OTHER BORROWINGS AND SUBORDINATED NOTES AND DEBENTURES Debt at June 30, 2026 and December 31, 2025 consisted of the following components: June 30, December 31, (In thousands) 2026 2025 Other Borrowings FHLB advances, net of discount, due 2026 to 2032, 3.75% to 5.53% secured by real estate loans $ 926,507 $ 286,597 Other long-term debt 14,749 15,656 Total other borrowings 941,256 302,253 Subordinated Notes and Debentures Subordinated notes payable, due 10/1/2035, fixed-to-floating rate (fixed rate of 6.25% through 9/30/2030, floating rate of 3.02% above the three-month SOFR rate, reset quarterly) 325,000 325,000 Unamortized debt issuance costs (3,633) (3,831) Valuation adjustments on hedged subordinated notes payable (9,339) (3,455) Total subordinated notes and debentures 312,028 317,714 Total other borrowings and subordinated debt $ 1,253,284 $ 619,967 In September 2025, the Company issued $325.0 million in aggregate principal amount, of 6.25% Fixed-to-Floating Rate Subordinated Notes (“2025 Notes”) at a public offering price equal to 100% of the aggregate principal amount of the 2025 Notes. The Company incurred $3.9 million in debt issuance costs related to the offering during September 2025. The 2025 Notes will mature on October 1, 2035 and will bear interest at an initial fixed rate of 6.25% per annum, payable semi-annually, in arrears. From and including October 1, 2030 to, but excluding, the maturity date or the date of earlier redemption, the interest rate resets quarterly to an annual interest rate equal to the then-current three month SOFR rate plus 302 basis points, payable quarterly, in arrears. Additionally, during the third quarter of 2025, the Company began utilizing interest rate swaps designated as fair value hedges to mitigate the risk of changes in the fair value of the aggregate principal amount of the 2025 Notes due to changes in market interest rates. See Note 22, Derivative Instruments, for further discussion regarding fair value hedges. The 2025 Notes will be subordinated in right of payment to the payment of the Company’s other existing and future senior indebtedness, including all of its general creditors. The 2025 Notes are obligations of the Company only and are not obligations of, and are not guaranteed by, any of its subsidiaries. The 2025 Notes qualify for Tier 2 capital treatment. The Company had total outstanding FHLB advances of $926.5 million and $286.6 million at June 30, 2026 and December 31, 2025, respectively. The outstanding FHLB advances as of June 30, 2026 were primarily overnight advances, which are due less than one year from origination and therefore were classified as short-term advances by the Company. At June 30, 2026, the FHLB advances outstanding were secured by mortgage loans and investment securities totaling approximately $7.29 billion and the Company had approximately $5.41 billion of additional advances available from the FHLB. The Company’s long-term debt primarily includes subordinated debt and other notes payable. The aggregate contractual annual maturities of long-term debt at June 30, 2026, are as follows: Year (In thousands) Remainder of 2026 $ 789 2027 1,649 2028 2,280 2029 9,689 2030 — Thereafter 313,877 Total $ 328,284 31 NOTE 11: CONTINGENT LIABILITIES In the ordinary course of its operations, the Company and its subsidiaries are parties to various legal proceedings incidental to the conduct of its business, including proceedings based on breach of contract claims, lender liability claims, and other ordinary-course claims, some of which seek substantial relief or damages. The Company establishes reserves for legal proceedings when potential losses become probable and can be reasonably estimated. While the ultimate resolution (including amounts thereof) of any legal proceedings cannot be determined at this time, based on information presently available and after consultation with legal counsel, management believes that the ultimate outcome in such proceedings, either individually or in the aggregate, will not have a material adverse effect on the Company’s business, consolidated results of operations, financial condition, or cash flows. It is possible, however, that future developments could result in an unfavorable outcome for or resolution of any of these proceedings, which may be material to the Company’s results of operations for a given fiscal period. NOTE 12: CAPITAL STOCK On February 27, 2009, at a special meeting, the Company’s shareholders approved an amendment to the Articles of Incorporation to establish 40,040,000 authorized shares of preferred stock, $0.01 par value. On April 27, 2022, the Company’s shareholders approved amendments to the Company’s Articles of Incorporation to remove an $80.0 million cap on the aggregate liquidation preference associated with the preferred stock and increase the number of authorized shares of the Company’s Class A common stock from 175,000,000 to 350,000,000. On October 29, 2019, the Company filed Amended and Restated Articles of Incorporation (“October Amended Articles”) with the Arkansas Secretary of State. The October Amended Articles classified and designated Series D Preferred Stock, Par Value $0.01 Per Share (“Series D Preferred Stock”), out of the Company’s authorized preferred stock. On November 30, 2021, the Company redeemed all of the Series D Preferred Stock, including accrued and unpaid dividends. On April 27, 2022, the Company’s shareholders approved an amendment to the Company’s Articles of Incorporation to remove the classification and designation for the Series D Preferred Stock. As of June 30, 2026, there were no shares of preferred stock issued or outstanding. On May 17, 2024, the Company filed a shelf registration with the SEC. The shelf registration statement provides increased flexibility and more efficient access to raise capital from time to time through the sale of common stock, preferred stock, debt securities, depository shares, warrants, purchase contracts, subscription rights, units or a combination thereof, subject to market conditions. Specific terms and prices are determined at the time of any offering under a separate prospectus supplement that the Company is required to file with the SEC at the time of the specific offering. On July 23, 2025, the Company closed a public offering of 18,653,000 shares of its Class A common stock, at a price to the public of $18.50 per share, which included 2,433,000 shares of the Company’s Class A common stock granted pursuant to the underwriters’ option to purchase additional shares at the public offering price, less underwriting discounts. In January 2024, the Company’s Board of Directors authorized a stock repurchase program (“2024 Program”) under which the Company could repurchase up to $175.0 million of its Class A common stock currently issued and outstanding. The 2024 Program terminated in January 2026, and the Company’s Board of Directors authorized a new stock repurchase program in January 2026 (“2026 Program”) under which the Company may repurchase up to $175.0 million of its Class A common stock currently issued and outstanding. The 2026 Program will be executed in accordance with Rule 10b-18 under the Securities Exchange Act of 1934, as amended, and will terminate on January 31, 2028 (unless terminated sooner). Under the 2026 Program, which replaced the 2024 Program, the Company may repurchase shares of its common stock through open market and privately negotiated transactions or otherwise. The timing, pricing, and amount of any repurchases under the 2026 Program will be determined by the Company’s management at its discretion based on a variety of factors, including, but not limited to, trading volume and market price of the Company’s common stock, corporate considerations, the Company’s working capital and investment requirements, general market and economic conditions, and legal requirements. The 2026 Program does not obligate the Company to repurchase any common stock and may be modified, discontinued, or suspended at any time without prior notice. The Company anticipates funding for this 2026 Program to come from available sources of liquidity, including cash on hand and future cash flow. During the three and six month periods ended June 30, 2026, the Company repurchased 662,082 shares at an average price of $21.52 per share under the 2026 Program. No shares were repurchased during the three and six month periods ended June 30, 2025. Market conditions and the Company’s capital needs, among other things, will drive decisions regarding future stock repurchases. 32 NOTE 13: UNDIVIDED PROFITS Simmons Bank, the Company’s subsidiary bank, is subject to legal limitations on dividends that can be paid to the parent company without prior approval of the applicable regulatory agencies. The approval of the Commissioner of the Arkansas State Bank Department is required if the total of all dividends declared by an Arkansas state bank in any calendar year exceeds seventy-five percent (75%) of the total of its net profits, as defined, for that year combined with seventy-five percent (75%) of its retained net profits of the preceding year. Since Simmons Bank is also under supervision of the Federal Reserve, it is further limited if the total of all dividends declared in any calendar year by Simmons Bank exceeds its net income to date for that year combined with its retained net profits for the preceding two years. At June 30, 2026, undivided profits of Simmons Bank were approximately $150.7 million, none of which were available for payment of dividends to the Company, without prior regulatory approval. The risk-based capital guidelines of the Federal Reserve Board and the Arkansas State Bank Department include the definitions for (1) a well-capitalized institution, (2) an adequately-capitalized institution, and (3) an undercapitalized institution. The criteria for a well-capitalized institution are: a 5% “Tier l leverage capital” ratio, an 8% “Tier 1 risk-based capital” ratio, 10% “total risk-based capital” ratio; and a 6.5% “common equity Tier 1 (CET1)” ratio. The Company and Simmons Bank must hold a capital conservation buffer of 2.5% composed of CET1 capital above its minimum risk-based capital requirements. Failure to meet this capital conservation buffer would result in additional limits on dividends, other distributions and discretionary bonuses. As of June 30, 2026, the Company and Simmons Bank met all capital adequacy requirements, including the capital conservation buffer, under the Basel III Capital Rules. The Company’s CET1 ratio was 11.60% at June 30, 2026. NOTE 14: STOCK-BASED COMPENSATION The Company’s Board of Directors has adopted various stock-based compensation plans, including the Amended and Restated 2023 Stock and Incentive Plan that was approved by shareholders and became effective May 13, 2026. The plans provide for the grant of incentive stock options, nonqualified stock options, stock appreciation rights, restricted stock awards, restricted stock units, performance stock units and stock awards. Pursuant to the plans, shares are reserved for future issuance by the Company upon exercise of stock options or awards of restricted stock, restricted stock units, performance stock units or stock awards granted to directors, officers and other key employees or consultants. The table below summarizes the transactions under the Company’s active stock-based compensation plans for the six months ended June 30, 2026: Stock Options Outstanding Non-vested Restricted Stock Units Outstanding Non-vested Performance Stock Units Outstanding (Shares in thousands) Number of Shares Weighted Average Exercise Price Number of Shares Weighted Average Grant-Date Fair Value Number of Shares Weighted Average Grant-Date Fair Value Beginning balance, January 1, 2026 62 $ 23.51 1,047 $ 20.24 512 $ 20.84 Granted — — 815 19.88 255 20.12 Stock options exercised — — — — — — Stock awards/units vested (earned) — — (401) 20.20 (7) 22.21 Forfeited/expired (62) 23.51 (76) 19.86 (209) 21.26 Balance, June 30, 2026 — $ — 1,385 $ 20.06 551 $ 19.94 Exercisable, June 30, 2026 — $ — Stock-based compensation expense was $7.0 million and $8.6 million during the six month periods ended June 30, 2026 and 2025, respectively. Stock-based compensation expense is recognized ratably over the requisite service period for all stock-based awards. There was no unrecognized stock-based compensation expense related to stock options at June 30, 2026. Unrecognized stock-based compensation expense related to non-vested stock awards and stock units was $25.3 million at June 30, 2026. At such date, the weighted-average period over which this unrecognized expense is expected to be recognized was 2.0 years. 33 There was no intrinsic value of stock options outstanding and stock options exercisable at June 30, 2026. Aggregate intrinsic value represents the difference between the Company’s closing stock price on the last trading day of the period, which was $22.65 as of June 30, 2026, and the exercise price multiplied by the number of options outstanding. There was no intrinsic value of stock options exercised during the six months ended June 30, 2026 and 2025. The fair value of the Company’s employee stock options granted is estimated on the date of grant using the Black-Scholes option-pricing model. This model requires the input of highly subjective assumptions, changes to which can materially affect the fair value estimate. There were no stock options granted during the six months ended June 30, 2026 and 2025. NOTE 15: EARNINGS PER SHARE (“EPS”) Basic EPS is computed by dividing reported net income available to common stockholders by the weighted average number of common shares outstanding during each period. Diluted EPS is computed by dividing reported net income available to common stockholders by the weighted average common shares and all potential dilutive common shares outstanding during the period. The computation of earnings per share is as follows: Three Months Ended June 30, Six Months Ended June 30, (In thousands, except per share data) 2026 2025 2026 2025 Net income available to common stockholders $ 66,691 $ 54,773 $ 135,235 $ 87,161 Average common shares outstanding 144,877 125,962 144,888 125,882 Average potential dilutive common shares 447 444 447 444 Average diluted common shares 145,324 126,406 145,335 126,326 Basic earnings per share $ 0.46 $ 0.43 $ 0.93 $ 0.69 Diluted earnings per share $ 0.46 $ 0.43 $ 0.93 $ 0.69 There were no stock options excluded from the three and six months ended June 30, 2026 earnings per share calculation as there were no outstanding stock options as of June 30, 2026. There were 317,660 stock options excluded from the earnings per share calculation for the three and six months ended June 30, 2025 due to the related stock option exercise price exceeding the average market price of the Company’s stock during the periods. NOTE 16: ADDITIONAL CASH FLOW INFORMATION The following is a summary of the Company’s additional cash flow information: Six Months Ended June 30, (In thousands) 2026 2025 Interest paid $ 220,219 $ 301,513 Income taxes paid 12,241 5,635 Transfers of loans to foreclosed assets held for sale 2,154 4,491 34 NOTE 17: OTHER INCOME AND OTHER OPERATING EXPENSES Other income for the three and six months ended June 30, 2026 was $8.6 million and $13.4 million, respectively. Other income for the three and six months ended June 30, 2025 was $4.8 million and $12.8 million, respectively. Other operating expenses consisted of the following: Three Months Ended June 30, Six Months Ended June 30, (In thousands) 2026 2025 2026 2025 Professional services $ 6,142 $ 6,192 $ 13,303 $ 11,059 Postage 2,308 2,250 4,596 4,530 Telephone 1,523 1,594 3,037 3,073 Credit card expense 2,962 3,191 6,069 6,220 Marketing 6,911 6,612 13,611 13,438 Software and technology 11,651 10,485 22,708 20,521 Operating supplies 421 487 707 1,114 Amortization of intangibles 3,097 3,098 6,194 6,625 Other expense 11,535 8,367 20,862 21,747 Total other operating expenses $ 46,550 $ 42,276 $ 91,087 $ 88,327 NOTE 18: OPERATING SEGMENTS Operating segments are components of an enterprise about which separate financial information is available that is regularly evaluated by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company is organized with community and commercial banking groups. Each of these groups provide one or more similar banking services, including such products and services as loans; time deposits, checking and savings accounts; treasury management; and credit cards. Loan products include consumer, real estate, commercial, agricultural, equipment, warehouse lending and SBA lending. The individual banking groups have similar operating and economic characteristics. While the CODM monitors the revenue streams of the various products, services, branch locations, divisions and groups, operations are managed, financial performance is evaluated, and management makes decisions on how to allocate resources, on a Company-wide basis. Accordingly, the respective groups are considered by management to be aggregated into one reportable operating segment. The Company also considers its wealth group, which provides trust and investment services, as well as insurance services, to be operating segments. Information on these segments is not reported separately since they do not meet the quantitative thresholds under ASC Topic 280-10-50-12, and, as a result, are reported within “Other” in the following table. The Company’s CODM is the chief executive officer. The CODM evaluates the performance of the Company’s reportable operating segments using net interest income and net income. The CODM analyzes on the spread between interest revenue and interest expense (net interest income) to assess performance and to allocate operating and capital resources. Therefore, interest revenue is presented net of interest expense. Additionally, the CODM reviews budgeted net income versus actual net income of the Company to allocate resources to meet the Company’s strategic objectives. 35 The following table provides a summary of the Company’s reportable operating segment results for the three and six months ended June 30, 2026 and 2025.

Additionally, some directors, officers and their associates and members of their immediate families have placed deposits with the Company’s subsidiary bank, Simmons Bank. Such loans and other extensions of credit, deposits and vendor contracts (which were not material) were made in the ordinary course of business, on substantially the same terms (including interest rates and collateral) as those prevailing at the time for comparable transactions with unrelated persons or through a competitive bid process. Further, in management’s opinion, these extensions of credit did not involve more than normal risk of collectability or present other unfavorable features. NOTE 20: COMMITMENTS AND CREDIT RISK The Company grants agribusiness, commercial and residential loans to customers primarily throughout Arkansas, Kansas, Missouri, Oklahoma, Tennessee and Texas, along with credit card loans to customers throughout the United States. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if deemed necessary, is based on management’s credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate and residential real estate. At June 30, 2026, the Company had outstanding commitments to extend credit aggregating approximately $795.8 million and $4.72 billion for credit card commitments and other loan commitments, respectively. At December 31, 2025, the Company had outstanding commitments to extend credit aggregating approximately $799.4 million and $4.19 billion for credit card commitments and other loan commitments, respectively. As of June 30, 2026, the Company had outstanding commitments to originate fixed-rate mortgage loans of approximately $28.4 million. At December 31, 2025, the Company had outstanding commitments to originate fixed-rate mortgage loans of approximately $20.5 million. The commitments extend over varying periods of time with the majority being disbursed within a thirty-day period. Standby letters of credit are conditional commitments issued by the Company to guarantee the performance of a customer to a third party. Those guarantees are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loans to customers. The Company had total outstanding letters of credit amounting to $82.3 million and $72.9 million at June 30, 2026 and December 31, 2025, respectively, with terms ranging from 9 months to 15 years. At June 30, 2026 and December 31, 2025, the Company had no deferred revenue under standby letter of credit agreements. The Company has purchased letters of credit from the FHLB as security for certain public deposits. The amount of the letters of credit was $944.4 million and $785.4 million at June 30, 2026 and December 31, 2025, respectively, and they expire in less than one year from issuance. NOTE 21: FAIR VALUE MEASUREMENTS ASC Topic 820, Fair Value Measurements defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. ASC Topic 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance also establishes a fair value hierarchy that requires the use of observable inputs and minimizes the use of unobservable inputs when measuring fair value. ASC Topic 820 describes three levels of inputs that may be used to measure fair value: •Level 1 Inputs – Quoted prices in active markets for identical assets or liabilities. •Level 2 Inputs – Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities in active markets; quoted prices for similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. •Level 3 Inputs – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. 37 In general, fair value is based upon quoted market prices, where available. If such quoted market prices are not available, fair value is based upon internally developed models that primarily use, as inputs, observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect counterparty credit quality and the Company’s creditworthiness, among other things, as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Furthermore, the reported fair value amounts have not been comprehensively revalued since the presentation dates, and therefore, estimates of fair value after the balance sheet date may differ significantly from the amounts presented herein. A more detailed description of the valuation methodologies used for assets and liabilities measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. Following is a description of the inputs and valuation methodologies used for assets measured at fair value on a recurring basis and recognized in the accompanying consolidated balance sheets, as well as the general classification of such assets pursuant to the valuation hierarchy. Available-for-sale and trading securities – Where quoted market prices are available in an active market, securities are classified within Level 1 of the valuation hierarchy. Level 1 securities would include highly liquid government bonds, mortgage products and certain other financial products. Other securities classified as available-for-sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the security’s terms and conditions, among other things. In order to ensure the fair values are consistent with ASC Topic 820, the Company periodically checks the fair values by comparing them to another pricing source, such as Bloomberg. The availability of pricing confirms Level 2 classification in the fair value hierarchy. The third-party pricing service is subject to an annual review of internal controls. In certain cases where Level 1 or Level 2 inputs are not available, securities are classified within Level 3 of the hierarchy. The Company’s investment in U.S. Treasury securities, if any, is reported at fair value utilizing Level 1 inputs. The remainder of the Company’s available-for-sale securities are reported at fair value utilizing Level 2 inputs. Mortgage loans held for sale – Mortgage loans held for sale are reported at fair value on an aggregate basis. Adjustments to fair value are recognized monthly and reflected in earnings. In determining the fair value of loans held for sale, the Company may consider outstanding investor commitments, discounted cash flow analyses with market assumptions or the fair value of the collateral if the loan is collateral dependent. Such loans are classified within either Level 2 or Level 3 of the fair value hierarchy. Where assumptions are made using significant unobservable inputs, such loans held for sale are classified as Level 3. At June 30, 2026 and December 31, 2025, the aggregate fair value of mortgage loans held for sale exceeded their cost. Derivative instruments – The Company’s derivative instruments are reported at fair value utilizing Level 2 inputs. The Company obtains fair value measurements from dealer quotes. 38 The following table sets forth the Company’s financial assets by level within the fair value hierarchy that were measured at fair value on a recurring basis as of June 30, 2026 and December 31, 2025. Fair Value Measurements Using (In thousands) Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Significant Unobservable Inputs (Level 3) June 30, 2026 Available-for-sale securities U.S. Government agencies $ 44,425 $ — $ 44,425 $ — Mortgage-backed securities 2,061,760 — 2,061,760 — State and political subdivisions 865,467 — 865,467 — Other securities 105,529 — 105,529 — Mortgage loans held for sale 16,450 — — 16,450 Assets held in trading accounts 14,541 14,541 — — Derivative asset 83,855 — 83,855 — Derivative liability (45,982) — (45,982) — December 31, 2025 Available-for-sale securities U.S. Government agencies $ 47,172 $ — $ 47,172 $ — Mortgage-backed securities 2,201,958 — 2,201,958 — States and political subdivisions 859,071 — 859,071 — Other securities 158,020 — 158,020 — Mortgage loans held for sale 17,438 — — 17,438 Assets held in trading accounts 11,685 11,685 — — Derivative asset 87,463 — 87,463 — Derivative liability (31,522) — (31,522) — Certain assets and liabilities are measured at fair value on a nonrecurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances. Assets and liabilities measured at fair value on a nonrecurring basis include the following: Individually assessed loans (collateral-dependent) – When the Company has a specific expectation to initiate, or has initiated, foreclosure proceedings, and when the repayment of a loan is expected to be substantially dependent on the liquidation of underlying collateral, the relationship is deemed collateral-dependent. Fair value of the loan is determined by establishing an allowance for credit loss for any exposure based on the valuation of the underlying collateral. The valuation of the collateral is determined by either an independent third-party appraisal or other collateral analysis. Discounts can be made by the Company based upon the overall evaluation of the independent appraisal. Collateral-dependent loans are classified within Level 3 of the fair value hierarchy due to the unobservable inputs used in determining their fair value such as collateral values and the borrower’s underlying financial condition. Collateral values supporting the individually assessed loans are evaluated quarterly for updates to appraised values or adjustments due to non-current valuations. Foreclosed assets and other real estate owned – Foreclosed assets and other real estate owned are reported at fair value, less estimated costs to sell. At foreclosure, if the fair value, less estimated costs to sell, of the real estate acquired is less than the Company’s recorded investment in the related loan, a write-down is recognized through a charge to the allowance for credit losses. Additionally, valuations are periodically performed by management and any subsequent reduction in value is recognized by a charge to income. The fair value of foreclosed assets and other real estate owned is estimated using Level 3 inputs based on unobservable market data. 39 The significant unobservable inputs (Level 3) used in the fair value measurement of collateral for collateral-dependent loans and foreclosed assets primarily relate to the specialized discounting criteria applied to the borrower’s reported amount of collateral. The amount of the collateral discount depends upon the condition and marketability of the collateral, as well as other factors which may affect the collectability of the loan. Management’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset. It is reasonably possible that a change in the estimated fair value for instruments measured using Level 3 inputs could occur in the future. As the Company’s primary objective in the event of default would be to liquidate the collateral to settle the outstanding balance of the loan, collateral that is less marketable would receive a larger discount. The following table sets forth the Company’s assets by level within the fair value hierarchy that were measured at fair value on a nonrecurring basis as of June 30, 2026 and December 31, 2025.

(2)Identified reserves of $11.6 million and $9.1 million were related to collateral-dependent loans for which fair value re-measurements took place during the periods ended June 30, 2026 and December 31, 2025, respectively. ASC Topic 825, Financial Instruments, requires disclosure in annual and interim financial statements of the fair value of financial assets and financial liabilities, including those financial assets and financial liabilities that are not measured and reported at fair value on a recurring basis or nonrecurring basis. The following methods and assumptions were used to estimate the fair value of each class of financial instruments not previously disclosed. Cash and cash equivalents – The carrying amount for cash and cash equivalents approximates fair value (Level 1). Interest bearing balances due from banks – The fair value of interest bearing balances due from banks – time is estimated using a discounted cash flow calculation that applies the rates currently offered on deposits of similar remaining maturities (Level 2). Loans – The fair value of loans is estimated by discounting the future cash flows, using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. Additional factors considered include the type of loan and related collateral, variable or fixed rate, classification status, remaining term, interest rate, historical delinquencies, loan to value ratios, current market rates and remaining loan balance. The loans were grouped together according to similar characteristics and were treated in the aggregate when applying various valuation techniques. The discount rates used for loans were based on current market rates for new originations of similar loans. Estimated credit losses were also factored into the projected cash flows of the loans. The fair value of loans is estimated on an exit price basis incorporating the above factors (Level 3). Deposits – The fair value of demand deposits, savings accounts and money market deposits is the amount payable on demand at the reporting date (i.e., their carrying amount) (Level 2). The fair value of fixed-maturity time deposits is estimated using a discounted cash flow calculation that applies the rates currently offered for deposits of similar remaining maturities (Level 3). Federal Funds purchased, securities sold under agreement to repurchase and short-term debt – The carrying amount for federal funds purchased, securities sold under agreement to repurchase and short-term debt are a reasonable estimate of fair value (Level 2). 40 Other borrowings – For short-term instruments, the carrying amount is a reasonable estimate of fair value. For long-term debt, rates currently available to the Company for debt with similar terms and remaining maturities are used to estimate the fair value (Level 2). Subordinated debentures – The fair value of subordinated debentures is estimated using the rates that would be charged for subordinated debentures of similar remaining maturities (Level 2). Accrued interest receivable/payable – The carrying amounts of accrued interest approximated fair value (Level 2). Commitments to extend credit, letters of credit and lines of credit – The fair value of commitments is estimated using the fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the present creditworthiness of the counterparties. For fixed rate loan commitments, fair value also considers the difference between current levels of interest rates and the committed rates. The fair values of letters of credit and lines of credit are based on fees currently charged for similar agreements or on the estimated cost to terminate or otherwise settle the obligations with the counterparties at the reporting date. The fair value of a financial instrument is the current amount that would be exchanged between willing parties, other than in a forced liquidation. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. The estimated fair values, and related carrying amounts, of the Company’s financial instruments are as follows: Carrying Fair Value Measurements (In thousands) Amount Level 1 Level 2 Level 3 Total June 30, 2026 Financial assets: Cash and cash equivalents $ 589,484 $ 589,484 $ — $ — $ 589,484 Interest bearing balances due from banks - time 100 — 100 — 100 Interest receivable 103,016 — 103,016 — 103,016 Loans, net 17,824,142 — — 17,635,637 17,635,637 Financial liabilities: Noninterest bearing transaction accounts 4,350,474 — 4,350,474 — 4,350,474 Interest bearing transaction accounts and savings deposits 11,133,265 — 11,133,265 — 11,133,265 Time deposits 4,244,371 — — 4,229,367 4,229,367 Federal funds purchased and securities sold under agreements to repurchase 46,216 — 46,216 — 46,216 Other borrowings 941,256 — 940,406 — 940,406 Subordinated notes and debentures 312,028 — 327,350 — 327,350 Interest payable 26,163 — 26,163 — 26,163 41 Carrying Fair Value Measurements (In thousands) Amount Level 1 Level 2 Level 3 Total December 31, 2025 Financial assets: Cash and cash equivalents $ 711,913 $ 711,913 $ — $ — $ 711,913 Interest bearing balances due from banks - time 100 — 100 — 100 Interest receivable 104,062 — 104,062 — 104,062 Loans, net 17,267,802 — — 17,056,124 17,056,124 Financial liabilities: Noninterest bearing transaction accounts 4,330,211 — 4,330,211 — 4,330,211 Interest bearing transaction accounts and savings deposits 11,141,169 — 11,141,169 — 11,141,169 Time deposits 4,712,658 — — 4,704,667 4,704,667 Federal funds purchased and securities sold under agreements to repurchase 21,383 — 21,383 — 21,383 Other borrowings 302,253 — 301,500 — 301,500 Subordinated notes and debentures 317,714 — 328,419 — 328,419 Interest payable 34,683 — 34,683 — 34,683 The fair value of commitments to extend credit, letters of credit and lines of credit is not presented since management believes the fair value to be insignificant. NOTE 22: DERIVATIVE INSTRUMENTS The Company utilizes derivative instruments to manage exposure to various types of interest rate risk for itself and its customers within policy guidelines. Transactions should only be entered into with an associated underlying exposure. All derivative instruments are carried at fair value. Derivative contracts involve the risk of dealing with institutional derivative counterparties and their ability to meet contractual terms. Institutional counterparties must have an investment grade credit rating and be approved by the Company’s asset/liability management committee. In arranging these products for its customers, the Company assumes additional credit risk from the customer and from the dealer counterparty with whom the transaction is undertaken. Credit risk exists due to the default credit risk created in the exchange of the payments over a period of time. Credit exposure on interest rate swaps is limited to the net favorable value and interest payments of all swaps with each counterparty. Access to collateral in the event of default is reasonably assured. Therefore, credit exposure may be reduced by the amount of collateral pledged by the counterparty. Hedge Structures The Company will seek to enter derivative structures that most effectively address the risk exposure and structural terms of the underlying position being hedged. The term and notional principal amount of a hedge transaction will not exceed the term or principal amount of the underlying exposure. In addition, the Company will use hedge indices which are the same as, or highly correlated to, the index or rate on the underlying exposure. Derivative credit exposure is monitored on an ongoing basis for each customer transaction and aggregate exposure to each counterparty is tracked. The Company has set a maximum outstanding notional contract amount at 25% of the Company’s assets. Fair Value Hedges For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative instrument as well as the offsetting loss or gain on the hedged asset or liability attributable to the hedged risk are recognized in current earnings. The gain or loss on the derivative instrument is presented on the same income statement line item as the earnings effect of the hedged item. 42 During the third quarter of 2021, the Company began utilizing interest rate swaps designated as fair value hedges to mitigate the effect of changing interest rates on the fair values of fixed rate callable AFS securities. The hedging strategy converts the fixed interest rates to variable interest rates based on federal funds rates. The two year forward start date for these swaps occurred during late third quarter of 2023 and involves the payment of fixed interest rates with a weighted average of 1.21% in exchange for variable interest rates based on federal funds rates. During the third quarter of 2025, the Company began utilizing step-down interest rate swaps designated as fair value hedges to mitigate the risk of changes in the fair value of the $325.0 million in aggregate principal amount of the 2025 Notes due to changes in market interest rates. These receive-fixed/pay-variable swaps have maturities ranging from 2026 to 2030 and the fixed interest rate decreases in predetermined intervals over the contractual term of the agreement. The following table summarizes the fair value hedges recorded in the accompanying consolidated balance sheets.

The gain or loss is reclassified into earnings in the same period during which the hedged asset or liability affects earnings and is presented in the same income statement line item as the earnings effect of the hedged asset or liability. During the third quarter of 2025, the Company executed step-down interest rate swaps on certain variable rate loans within the CRE and commercial and industrial portfolios with maturity dates ranging from 2026 to 2029 and certain securities within the variable rate commercial MBS portfolio with maturity dates ranging from 2026 to 2027. These receive-fixed/pay-variable swaps are used to manage variability in future cash flows related to interest rate exposure within each portfolio.

The Company enters into such agreements with customers, then offsetting agreements are executed between the Company and an approved dealer counterparty to minimize market risk from changes in interest rates. The counterparty contracts are identical to customer contracts in terms of notional amounts, interest rates, and maturity dates, except for a fixed pricing spread or fee paid to the Company by the dealer counterparty. These interest rate swaps carry varying degrees of credit, interest rate and market or liquidity risks. The fair value of these derivative instruments is recognized as either derivative assets or liabilities in the accompanying consolidated balance sheets. The Company has a limited number of swaps that are standalone without a similar agreement with the loan customer. The following table summarizes the fair values of loan derivative contracts recorded in the accompanying consolidated balance sheets. June 30, 2026 December 31, 2025 (In thousands) Notional Fair Value Notional Fair Value Derivative assets $ 1,505,189 $ 19,208 $ 1,190,958 $ 26,734 Derivative liabilities 1,506,072 19,148 1,191,858 26,682 Risk Participation Agreements The Company has a limited number of Risk Participation Agreement swaps, that are associated with loan participations, where the Company is not the counterparty to the interest rate swaps that are associated with the risk participation sold. The interest rate swap mark to market only impacts the Company if the swap is in a liability position to the counterparty and the customer defaults on payments to the counterparty. The notional amount of these contingent agreements is $4.0 million as of June 30, 2026. Energy Hedging The Company, from time-to-time, has provided energy derivative services to qualifying, high quality oil and gas borrowers for hedging purposes. The Company has served as an intermediary on energy derivative products between the Company’s borrowers and dealers. The Company will only enter into back-to-back trades, thus maintaining a balanced book between the dealer and the borrower. The energy hedging risk exposure to the Company’s customer would increase as energy prices for crude oil and natural gas rise. As prices decrease, exposure to the exchange would increase. These risks are mitigated by customer credit underwriting policies and establishing a predetermined hedge line for each borrower and by monitoring the exchange margin. The Company has no outstanding notional values related to energy hedge swap contracts as of June 30, 2026. Currently, the Company generally does not intend to offer hedging services to any remaining energy related customers. 45 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the Shareholders, Board of Directors and Audit Committee Simmons First National Corporation Pine Bluff, Arkansas Results of Review of Interim Financial Information We have reviewed the consolidated balance sheet of Simmons First National Corporation and subsidiaries (the “Company”) as of June 30, 2026, and the related consolidated statements of income, comprehensive income (loss), and stockholders’ equity for the three and six month periods ended June 30, 2026 and 2025, and cash flows for the six month periods ended June 30, 2026 and 2025, and the related notes (collectively referred to as the “interim financial information”). Based on our reviews, we are not aware of any material modifications that should be made to the interim financial information referred to above for it to be in conformity with accounting principles generally accepted in the United States of America. We have previously audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheet of the Company and subsidiaries as of December 31, 2025, and the related consolidated statements of income (loss), comprehensive income (loss), stockholders’ equity and cash flows for the year then ended (not presented herein), and in our report dated February 25, 2026, we expressed an unqualified opinion on those consolidated financial statements. In our opinion, the information set forth in the accompanying consolidated balance sheet as of December 31, 2025, is fairly stated, in all material respects, in relation to the consolidated balance sheet from which it has been derived. Basis for Review Results These interim financial statements are the responsibility of the Company’s management. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our review in accordance with the standards of the PCAOB. A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the PCAOB, the objective of which is the expression of an opinion regarding the financial statements taken as a whole. Accordingly, we do not express such an opinion. /s/ Forvis Mazars, LLP Little Rock, Arkansas August 5, 2026 46
