SIMMONS FIRST NATIONAL CORP (SFNC) Business

ITEM 1. BUSINESS

Company Overview

Simmons First National Corporation, an Arkansas corporation organized in 1968, is a financial holding company registered under the Bank Holding Company Act of 1956, as amended. The terms “Company,” “we,” “us,” and “our” refer to Simmons First National Corporation and, where appropriate, its subsidiaries. The Company is headquartered in Pine Bluff, Arkansas, and had total consolidated assets of $24.54 billion, total consolidated loans of $17.49 billion, total consolidated deposits of $20.18 billion and equity capital of $3.42 billion, each as of December 31, 2025. The Company, through its subsidiaries, provides banking and other financial products and services in markets located in Arkansas, Kansas, Missouri, Oklahoma, Tennessee and Texas.

We seek to build shareholder value by, among other things, focusing on strong asset quality, maintaining strong capital, managing our liquidity position, improving our operational efficiency and opportunistically growing our business, both organically and through mergers with and acquisitions of other financial institutions. Our business philosophy centers on building strong, deep customer relationships through excellent customer service and integrity in our operations. While we have grown in recent years into a regional financial institution and one of the largest bank/financial holding companies headquartered in the State of Arkansas, we continue to emphasize, where practicable, a community-based mindset focused on local associates responding to local banking needs and making business decisions in the markets they serve. Those efforts, though, are buttressed by experienced, centralized support functions in select, critical areas. While we serve a variety of customers and industries, we are not dependent on any single customer or industry.

Subsidiary Bank

The Company’s lead subsidiary, Simmons Bank (“Simmons Bank” or the “Bank”), is an Arkansas state-chartered bank that has been in operation since 1903.

Simmons Bank provides banking and other financial products and services to individuals and businesses using a network of approximately 222 financial centers in Arkansas, Kansas, Missouri, Oklahoma, Tennessee and Texas. Simmons Bank offers commercial banking products and services to business and other corporate customers. Simmons Bank extends loans for a broad range of corporate purposes, including (among others) financing commercial real estate, construction of particular properties, commercial and industrial uses, acquisition and equipment financings, and other general corporate needs. Simmons Bank also engages in small business administration (“SBA”) and agricultural finance lending, and it offers corporate credit card products, as well as corporate deposit products and treasury management services.

In addition, Simmons Bank offers a variety of consumer banking products and services, including (among others) savings, time, and checking deposit products; ATM services; internet and mobile banking platforms; overdraft facilities; real estate, home equity, and other consumer loans and lines of credit; consumer credit card products; and safe deposit boxes. Simmons Bank also maintains a networking arrangement with a third-party broker-dealer that offers brokerage services to Simmons Bank customers, as well as a trust department that provides a variety of trust, investment, agency, and custodial services for individual and corporate clients (including, among others, administration of estates and personal trusts as well as management of investment accounts).

Additionally, 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.

Community Banking, Commercial Banking and Wealth Strategy

To both effectively compete for and service the needs of different types of customers, Simmons Bank now operates using three main groups: a community banking group (which generally focuses on retail, small-to-mid-size customer relationships plus mortgage lending), a commercial banking group (which generally focuses on larger, more complex customers, sometimes with intricate or unique banking needs) and a wealth group (which generally focuses on serving investment and trust needs of consumers and businesses). Each of these groups is supported by Simmons Bank’s various operations divisions.

Growth Strategy

Over the years, as we have expanded our markets and services, our growth strategy has evolved and diversified. We have used varying acquisition and internal branching methods to enter key growth markets and increase the size of our footprint.

Since 1990, we have completed 21 whole bank acquisitions, one trust company acquisition, five bank branch acquisitions, one bankruptcy (363) acquisition, four Federal Deposit Insurance Corporation (“FDIC”) failed bank acquisitions and four Resolution Trust Corporation failed thrift acquisitions. The following summary provides additional details concerning our more recent acquisition activity.

In October 2021, we completed the acquisition of Landmark Community Bank (“Landmark”), headquartered in Collierville, Tennessee, as well as the acquisition of Triumph Bancshares, Inc. (“Triumph”), including its wholly-owned bank subsidiary, Triumph Bank, headquartered in Memphis, Tennessee. Landmark had total assets of $968.8 million, while Triumph provided us with $847.2 million in assets. These combined acquisitions allowed us to expand our existing footprint in Tennessee and to further enhance our scale in two of our key Tennessee growth markets – Memphis and Nashville. The systems conversions for both Landmark and Triumph Bank were completed in October 2021, at which time Landmark and Triumph Bank were merged into Simmons Bank.

In April 2022, we completed the acquisition of Spirit of Texas Bancshares, Inc. (“Spirit”), headquartered in Conroe, Texas, including its wholly-owned bank subsidiary, Spirit of Texas Bank SSB (“Spirit Bank”). We acquired approximately $3.1 billion in assets and further strengthened our position in Texas. The systems conversion was completed in April 2022, at which time Spirit Bank merged into Simmons Bank.

Merger and Acquisition Strategy

Merger and acquisition activities have been an important part of the Company’s historical growth strategy. While we will continue to consider strategic merger and acquisition opportunities if and as they arise, and while we continue to believe that current market and industry conditions will continue to cause various financial institutions to seek merger partners in the near-to-intermediate future, in the near term, we are continuing our enhanced focus on ensuring that we capitalize on organic growth opportunities in many of the markets that we have had the fortune to enter through previous mergers and acquisitions. We also continue to focus on evaluating and, where appropriate, enhancing our people, processes and systems so that we are able to more effectively and efficiently compete as an organization of the size and scale that we now have achieved.

To the extent that a strategic merger and acquisition opportunity becomes of interest, we believe our community banking philosophy, access to capital and successful merger and acquisition history would position us as a purchaser of choice for a community and regional bank seeking a strong partner.

As consolidations continue to unfold in the banking industry, the management of risk is an important consideration in how the Company evaluates and consummates these transactions. The process of merging or acquiring banking organizations is extremely complex; it requires a great deal of time and effort from both buyer and seller. The business, legal, operational, organizational, accounting and tax issues all must be addressed if the merger or acquisition is to be successful. The senior management teams of both the Company and Simmons Bank have extensive experience in acquiring banks, branches and deposits and post-acquisition integration of operations. We believe this experience positions us to successfully acquire and integrate banks to the extent a compelling strategic opportunity presents itself.

Loan Risk Assessment

As part of our ongoing risk assessment and analysis, the Company utilizes credit policies and procedures, internal credit expertise and several internal layers of review. The internal layers of ongoing review include Division Presidents, Division and Senior Credit Officers, the Chief Credit Officer and Corporate Credit Officers, an Executive Loan Committee, a Senior Credit Committee, and a Directors’ Credit Committee.

Additionally, the Company has an Asset Quality Review Committee comprised of management that meets quarterly to review the adequacy of the allowance for credit losses. The Committee reviews the status of past due, non-performing and other impaired loans, reserve ratios, and additional performance indicators for Simmons Bank. The appropriateness of the allowance for credit losses is determined based upon the aforementioned performance factors, and provision adjustments are made accordingly.

The Board of Directors reviews the adequacy of its allowance for credit losses on a periodic basis giving consideration to past due loans, non-performing loans, other impaired loans, and current economic conditions. Our loan review department monitors loan information monthly. In order to verify the accuracy of the monthly analysis of the allowance for credit losses, the loan review department performs a detailed review of loans across each product line and all divisions on an annual basis or more often if warranted. Additionally, we have instituted a Special Asset Committee for the purpose of reviewing criticized loans in regard to collateral adequacy, workout strategies and proper reserve allocations.

Competition

There is significant competition among commercial banks in our various market areas. In addition, we also compete with other providers of financial services, such as savings and loan associations, credit unions, finance companies, securities firms, insurance companies, full service brokerage firms, discount brokerage firms and fintech companies. Some of our competitors have greater resources and, as such, may have higher lending limits and may offer other services that we do not provide. Some of our competitors operate only in digital channels, which may result in those competitors investing greater resources in information technology and digital product and service delivery without the overhead associated with a branch network. We generally compete on the basis of customer service and responsiveness to customer needs, available loan and deposit products, the rates of interest charged on loans, the rates of interest paid for funds, and the availability and pricing of trust and brokerage services.

Nonbank competitors are increasingly offering products and services that traditionally were bank products. Many of these nonbank competitors are not subject to the same extensive federal regulations that govern bank holding companies and federally insured banks, which may allow them to offer greater lending limits and certain products and services that the Company and its affiliates do not provide.

Human Capital

Our associates are a critical component of our success. Because our business depends on our ability to attract, develop, and retain highly qualified, skilled operations, information technology, production and other associates, as well as managers who are experienced and effective at leading their respective business areas, we have implemented wide-ranging programs focused on identifying and recruiting new talent, as well as enhancing the skills, qualifications, and engagement of our current associate base. In recruiting, we employ a variety of strategies, including, among other things, the use of in-house recruiters, search firms, and employment agencies, designed to attract qualified candidates. Among other opportunities, we offer student internships and a banker trainee program that provides recent graduates with the opportunity to gain insight into several business areas. We believe our compensation program, which, in addition to base and incentive compensation, includes health, retirement, and an array of other benefit plans and programs, is competitive within the financial industry, and we periodically review our plans and programs, as well as market surveys, to help ensure that our compensation program is consistent with our level of performance and that we have a current understanding of peer practices.

We provide our associates a variety of professional development opportunities, including participation in industry conferences, instructor-led continuing education and training sessions, as well as online training sessions that focus on industry, regulatory, business, and leadership topics. We offer mentorship opportunities through our “Simmons Sidekick” and “Ambassadors” programs, and we provide tuition reimbursement for associates to attend a higher education facility to obtain bachelor’s and master’s degrees that are relevant to the finance industry and/or their positions within the Company. We seek to promote from within the Company when feasible and have established programs, such as our “Next Generation Leadership Program,” to help develop future leadership talent.

We are committed to maintaining a strong culture that not only engages associates but also serves as a catalyst for growth. Our values-based culture is memorialized in a set of “Culture Cornerstones” that are communicated to all associates and incorporated in various ways throughout our operations. We strive for all six of our Culture Cornerstones - Better Together; Integrity; Passion; High Performance; Pursue Growth; and Build Loyalty - to be reflected in everything we do, including how we interact with each other, how we interact with our customers, and how we interact with our vendors and business partners. We have implemented extensive training and programming to support leaders and associates to emphasize and reinforce our culture cornerstones and ensure a pervasive, shared value system. Finally, we are also committed to promoting our associates’ well-being. Our wellness program, “Ultimate You,” assists associates in improving their level of physical, financial, and mental fitness through offerings such as financial literacy training, channels for counseling and health-focused challenges and contests.

As of December 31, 2025, the Company and its subsidiaries had approximately 2,917 full time equivalent associates. None of our associates are represented by any union or similar groups, and we have not experienced any labor disputes or strikes arising from any such organized labor groups. We consider our relationship with our associates to be good and strive to operate with an “open door policy” where associate concerns and issues can be discussed anytime directly with leadership or human resources. We have been recognized with “Best Places to Work” awards in several of our markets.

SUPERVISION AND REGULATION

The Company and its subsidiaries are extensively regulated under both federal and state laws. The following description summarizes certain aspects of that regulation that are material to the Company and its subsidiary bank, Simmons Bank, and is not a complete description of all applicable laws or regulations, or all aspects of those regulations, that affect us. To the extent that any specific statutory or regulatory provision or proposal is described in this Annual Report on Form 10-K, such description is qualified in its entirety by reference to the statutory or regulatory provision or proposal.

Proposals to change the laws, regulations, and policies governing the banking industry are frequently raised at both the state and federal levels. These laws and regulations, and changes thereto, impose compliance costs and create obligations and, in some cases, reporting obligations, and compliance with these laws, regulations, and obligations may require us to use significant resources. The likelihood and timing of any changes in laws and regulations and the supervisory environment, and the impact such changes may have on us, are difficult to predict and assess.

The Company

The Company, as a bank holding company, is subject to both federal and state regulation. Under federal law, a bank holding company generally must obtain approval from the Board of Governors of the Federal Reserve System (“FRB”) before acquiring ownership or control of the assets or stock of a bank or a bank holding company. Prior to approval of any proposed acquisition, the FRB will review the effect on competition of the proposed acquisition, as well as other regulatory issues.

The federal law generally prohibits a bank holding company from directly or indirectly engaging in non-banking activities. This prohibition does not include loan servicing, liquidating activities or other activities so closely related to banking as to be a proper incident thereto. Bank holding companies, including the Company, which have elected to qualify as financial holding companies, are authorized to engage in financial activities. Financial activities include any activity that is financial in nature or any activity that is incidental or complimentary to a financial activity.

As a financial holding company, we are required to file with the FRB an annual report and such additional information as may be required by law. From time to time, the FRB examines the financial condition of the Company and its subsidiaries. For the Company to maintain financial holding company status, each of the Company’s bank subsidiaries must be “well-capitalized” and “well-managed” as defined by the FRB. Bank holding companies are not permitted to engage in unsafe and unsound banking practices. The FRB, through civil and criminal sanctions, is authorized to exercise enforcement powers over bank holding companies (including financial holding companies) and non-banking subsidiaries, to limit activities that represent unsafe or unsound practices or constitute violations of law. We also must file annual, quarterly and other periodic reports with, and comply with other regulations of, the SEC, as well as the rules of the Nasdaq Global Select Market.

Federal law also requires the Company to act as a source of financial and managerial strength for our bank subsidiary and to commit resources to support that subsidiary. This support may be required by federal banking agencies even at times when a bank holding company may not have the resources to provide the support. Further, if the FRB believes that a bank holding company’s activities, assets or affiliates represent a significant risk to the financial safety, soundness or stability of its subsidiary bank, then the FRB could require that bank holding company to terminate the activities, liquidate the assets or divest the affiliates. Federal banking agencies, including the FRB, may require these and other actions in support of a subsidiary bank even if such actions are not in the best interests of the bank holding company or its stockholders.

We are subject to certain laws and regulations of the State of Arkansas applicable to financial and bank holding companies, including examination and supervision by the Arkansas Bank Commissioner. Under Arkansas law, a financial or bank holding company is prohibited from owning more than one subsidiary bank if any subsidiary bank owned by the holding company has been chartered for less than five years and, further, requires the approval of the Arkansas Bank Commissioner for any acquisition of more than 25% of the capital stock of any other bank located in the State of Arkansas. No bank acquisition may be approved if, after such acquisition, the holding company would control, directly or indirectly, banks having 25% of the total bank deposits in the State of Arkansas, excluding deposits of other banks and public funds.

Additionally, under federal and state law, acquisitions of the Company’s common stock above certain thresholds or in connection with certain governance rights or business relationships may be subject to certain regulatory restrictions, including prior notice and approval requirements, and investors in the Company’s common stock are responsible for ensuring that they comply with these restrictions to the extent they are applicable.

Federal legislation allows bank holding companies (including financial holding companies) from any state to acquire banks located in any state without regard to state law, provided that the holding company (1) is well capitalized, (2) is well managed, (3) would not control more than 10% of the insured deposits in the United States or more than 30% of the insured deposits in such state, and (4) such bank has been in existence at least five years if so required by the applicable state law.

The principal source of the Company’s liquidity is dividends from Simmons Bank, the payment of which is subject to certain limitations imposed by federal and state laws. The approval of the Arkansas Bank Commissioner is, for instance, 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. Under the foregoing dividend restrictions, and while maintaining its “well capitalized” status, at December 31, 2025, Simmons Bank had paid to the Company all available dividends. While past dividends are not necessarily indicative of amounts that may be paid or available to be paid in future periods, net profits of Simmons Bank and cash balances at the Company are projected to be sufficient to pay quarterly dividends on the Company’s common stock at current levels and interest and principal on the Company’s debt as well as meet other liquidity needs.

9

A bank holding company’s repurchases of shares of its common stock or redemption of its debt securities may, in certain circumstances, be subject to approval or notice requirements under other regulations, policies, or supervisory expectations of the bank holding company’s regulators, may be discouraged by regulators in the form of supervisory feedback on the bank holding company’s regulatory capital levels or plan, and must comply with all applicable state and federal corporate and securities laws and regulations.

Subsidiary Bank

Simmons Bank is an Arkansas state-chartered bank and a member of the Federal Reserve System through the Federal Reserve Bank of St. Louis. Due to the Company’s typical acquisition process, there may be brief periods of time during which the Company may operate another subsidiary bank that the Company acquired through a merger with a target bank holding company as a separate subsidiary while preparing for the merger and integration of that subsidiary bank into Simmons Bank. However, it is the Company’s intent to generally maintain Simmons Bank as the Company’s sole subsidiary bank.

The lending powers of the subsidiary bank are generally subject to certain restrictions, including the amount which may be loaned to a single borrower. Our subsidiary bank is a member of the FDIC, which provides insurance on deposits of each member bank up to applicable limits by the Deposit Insurance Fund. For this protection, our bank pays a statutory assessment to the FDIC each year.

Furthermore, as a member of the Federal Reserve System, our subsidiary bank is required by law to maintain reserves against its transaction deposits as required by the FRB. The reserves must be held in cash or with the FRB. Banks are permitted to meet this requirement by maintaining the specified amount as an average balance over a two-week period. During 2020, due to the COVID-19 pandemic, the FRB acting pursuant to the Federal Reserve Act reduced the reserve requirements to zero until further notice. As a result, as of December 31, 2025, the Company’s reserve balances were zero.

Pursuant to federal laws and regulations, national and state-chartered banks may establish branches in their home states, as well as in other states. Applications to establish branches must be filed with the appropriate primary federal regulator and, where applicable, the bank’s state regulatory authority. As an Arkansas state-chartered bank, our subsidiary bank files branch applications with both the FRB and the Arkansas State Bank Department.

Federal laws and regulations also restrict banks, including our subsidiary bank, from establishing certain tying arrangements. In particular, subject to certain exceptions, banks, including our subsidiary bank, are prohibited from extending credit, leasing or selling property, furnishing services, or varying prices on the condition that the customer obtain an additional product or service from the bank or its affiliates or not obtain services of a competitor of the bank or its affiliates.

Transactions with Affiliates and Insiders

Under federal law, transactions between insured depository institutions and their affiliates are governed by Sections 23A and 23B of the Federal Reserve Act and its implementing regulation, Regulation W. In a bank holding company context, at a minimum, the parent holding company of a bank, any companies which are controlled by such parent holding company, and financial subsidiaries of the bank, are affiliates of the bank. Generally, Sections 23A and 23B of the Federal Reserve Act are intended to protect insured depository institutions from losses arising from transactions with non-insured affiliates by limiting the extent to which a bank or its subsidiaries may engage in covered transactions with any one affiliate and with all affiliates of the bank in the aggregate, and requiring that such transactions be on terms consistent with safe and sound banking practices.

Loans to executive officers, directors, or any person who directly or indirectly, or acting through or in concert with one or more persons, owns, controls, or has the power to vote more than 10% of any class of voting securities of a bank (“10% Shareholders”), are subject to Sections 22(g) and 22(h) of the Federal Reserve Act and their corresponding regulations (Regulation O) and Section 13(k) of the Exchange Act relating to the prohibition on personal loans to executives (which exempts financial institutions in compliance with the insider lending restrictions of Section 22(h) of the Federal Reserve Act). Among other things, these loans must be made on terms substantially the same as those prevailing on transactions made to unaffiliated individuals, except that such insiders may receive preferential loans made under a benefit or compensation program that is widely available to the bank's employees and does not give preference to the insider over the employees, and certain extensions of credit to those persons must first be approved in advance by a disinterested majority of the entire Board of Directors.

10

Section 22(h) of the Federal Reserve Act and its implementing regulation, Regulation O, prohibits loans to any directors, executive officers, and principal stockholders and their related interests where the aggregate amount exceeds an amount equal to 15% of an institution’s unimpaired capital and surplus plus an additional 10% of unimpaired capital and surplus in the case of loans that are fully secured by readily marketable collateral, or when the aggregate amount on all of the extensions of credit outstanding to all of these persons would exceed the Bank’s unimpaired capital and unimpaired surplus. Section 22(g) of the Federal Reserve Act places additional limitations on loans to executive officers and identifies limited circumstances in which the Bank is permitted to extend credit to executive officers.

As a result, our subsidiary bank is limited in its ability to make extensions of credit to the Company, investing in the stock or other securities of the Company, and engaging in other affiliated financial transactions with the Company.

Potential Enforcement Action for Bank Holding Companies and Banks

Enforcement proceedings seeking civil or criminal sanctions may be instituted against any bank, any financial or bank holding company, any director, officer, employee or agent of the bank or holding company, which is believed by the federal banking agencies to be violating any applicable banking law, regulation or administrative pronouncement or engaged in unsafe and unsound practices. In more serious cases, enforcement actions may include the issuance of directives to increase capital; the issuance of formal and informal agreements; the imposition of civil monetary penalties; the issuance of a cease and desist order that can be judicially enforced; the issuance of removal and prohibition orders against officers, directors, and other institution-affiliated parties; the termination of a bank’s deposit insurance; the appointment of a conservator or receiver for a bank; and the enforcement of such actions through injunctions or restraining orders based upon a judicial determination that the agency would be harmed if such equitable relief was not granted.

Risk-Weighted Capital Requirements for the Company and the Subsidiary Bank

Effective January 1, 2015, the Company and its subsidiary bank became subject to new capital regulations (“Basel III Capital Rules”) adopted by the Federal Reserve in July 2013 establishing a new comprehensive capital framework for U.S. banks. The Basel III Capital Rules were fully implemented as of January 1, 2019. For a tabular summary of our risk-weighted capital ratios, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Capital” and Note 22, Stockholders’ Equity, of the Notes to Consolidated Financial Statements.

The Basel III Capital Rules include a common equity Tier 1 capital to risk-weighted assets (“CET1”) ratio of 4.5% and a common equity Tier 1 capital conservation buffer of 2.5% of risk-weighted assets. CET1 generally consists of common stock; retained earnings; accumulated other comprehensive income; and certain minority interests, all subject to applicable regulatory adjustments and deductions. The Company and its subsidiary bank must hold a capital conservation buffer composed of CET1 capital above its minimum risk-based capital requirements.

A banking organization’s qualifying total capital consists of two components: Tier 1 Capital and Tier 2 Capital. Tier 1 Capital is an amount equal to the sum of common stockholders’ equity, hybrid capital instruments (instruments with characteristics of debt and equity) in an amount up to 25% of Tier 1 Capital, certain preferred stock and the minority interest in the equity accounts of consolidated subsidiaries. For bank holding companies and financial holding companies, goodwill (net of any deferred tax liability associated with that goodwill) may not be included in Tier 1 Capital. Identifiable intangible assets may be included in Tier 1 Capital for banking organizations, in accordance with certain further requirements. At least 50% of the banking organization’s total regulatory capital must consist of Tier 1 Capital.

Tier 2 Capital is an amount equal to the sum of the qualifying portion of the allowance for credit losses, certain preferred stock not included in Tier 1, hybrid capital instruments (instruments with characteristics of debt and equity), certain long-term debt securities and eligible term subordinated debt, in an amount up to 50% of Tier 1 Capital. The eligibility of these items for inclusion as Tier 2 Capital is subject to certain additional requirements and limitations of the federal banking agencies.

The Basel III Capital Rules expanded the risk-weighting categories from the previous four Basel I-derived categories (0%, 20%, 50% and 100%) to a much larger and more risk-sensitive number of categories, depending on the nature of the assets, generally ranging from 0% for U.S. government and agency securities, to 600% for certain equity exposures, and resulting in higher risk weights for a variety of asset categories, including many residential mortgages and certain commercial real estate.

Accordingly, under the fully-phased in Basel III Capital Rules, the capital standards applicable to the Company include an additional capital conservation buffer of 2.5% of CET1, effectively resulting in minimum ratios inclusive of the capital conservation buffer of (1) CET1 to risk-weighted assets of at least 7.0%, (2) Tier 1 capital to risk-weighted assets of at least 8.5%, and (3) Total capital to risk-weighted assets of at least 10.5%.

11

In August 2020, the FRB, along with the other federal bank regulatory agencies, adopted a final rule that allows the Company and the Bank to phase-in the impact of adopting the Current Expected Credit Losses (or “CECL”) methodology up to two years, with a three-year period to phase out the cumulative benefit to regulatory capital provided during the two-year delay.

Prompt Corrective Action

The Basel III Capital Rules also affected the FDIC’s prompt correction action standards. Those standards seek to address problems associated with undercapitalized financial institutions and provide for five capital categories: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized.

For purposes of prompt corrective action, to be:

•well capitalized, a bank must have a total risk based capital ratio of at least 10%, a Tier 1 risk based capital ratio of at least 8%, a CET1 risk based capital ratio of at least 6.5%, and a Tier 1 leverage ratio of at least 5%;

•adequately capitalized, a bank must have a total risk based capital ratio of at least 8%, a Tier 1 risk based capital ratio of at least 6%, a CET1 risk based capital ratio of at least 4.5%, and a Tier 1 leverage ratio of at least 4%;

•undercapitalized, a bank would have a total risk based capital ratio of less than 8%, a Tier 1 risk based capital ratio of less than 6%, a CET1 risk based capital ratio of less than 4.5%, and a Tier 1 leverage ratio of less than 4%;

•significantly undercapitalized, a bank would have a total risk based capital ratio of less than 6%, a Tier 1 risk based capital ratio of less than 4%, a CET1 risk based capital ratio of less than 3%, and a Tier 1 leverage ratio of less than 3%; and

•critically undercapitalized, a bank would have a ratio of tangible equity to total assets that is less than or equal to 2%.

Institutions that fall into the latter three categories are subject to restrictions on their growth and are required to submit a capital restoration plan. There is also a method by which an institution may be downgraded to a lower capital category based on supervisory factors other than capital. As of December 31, 2025, Simmons Bank was “well capitalized” based on the aforementioned ratios.

Federal Deposit Insurance Corporation Improvement Act

The Federal Deposit Insurance Corporation Improvement Act (“FDICIA”), enacted in 1991, requires the FDIC to increase assessment rates for insured banks and authorizes one or more “special assessments,” as necessary for the repayment of funds borrowed by the FDIC or any other necessary purpose. As directed in FDICIA, the FDIC has adopted a transitional risk-based assessment system, under which the assessment rate for insured banks will vary according to the level of risk incurred in the bank’s activities. The risk category and risk-based assessment for a bank is determined, in part, from its prompt corrective action, as well capitalized, adequately capitalized or undercapitalized. Please refer to the section below titled “FDIC Deposit Insurance and Assessments” for more information.

Pursuant to the FDICIA and Federal Deposit Insurance Act (“FDIA”), the federal banking agencies must promptly mandate corrective actions by banks that fail to meet the capital and related requirements in order to minimize losses to the FDIC and the Deposit Insurance Fund. As of December 31, 2025, the Bank was well capitalized under these regulations.

The federal banking agencies are also required by FDICIA to prescribe standards for banks and bank holding companies (including financial holding companies) relating to operations and management, asset quality, earnings, stock valuation and compensation. A bank or bank holding company that fails to comply with such standards will be required to submit a plan designed to achieve compliance. If no plan is submitted or the plan is not implemented, the bank or holding company would become subject to additional regulatory action or enforcement proceedings.

A variety of other provisions included in FDICIA may affect the operations of the Company and the subsidiary bank, including reporting requirements, regulatory standards for real estate lending, “truth in savings” provisions, and the requirement that a depository institution give 90 days prior notice to customers and regulatory authorities before closing any branch.

Dodd-Frank Wall Street Reform and Consumer Protection Act

Enacted in 2010, the Dodd-Frank Wall Street Reform and Consumer Protection Act (“Dodd-Frank Act”), significantly changed the regulation of financial institutions and the financial services industry. The Dodd-Frank Act included provisions affecting large and small financial institutions alike, including several provisions that profoundly affected how community banks, thrifts, and small bank and thrift holding companies are regulated. Among other things, these provisions relaxed rules regarding interstate branching, allow financial institutions to pay interest on business checking accounts, and revised capital requirements on bank and thrift holding companies.

The Dodd-Frank Act also established the Bureau of Consumer Financial Protection (“CFPB”) as an independent entity within the Federal Reserve and provided it with the authority to promulgate consumer protection regulations applicable to all entities offering consumer financial services or products, including banks. Additionally, the Dodd-Frank Act included a series of provisions covering mortgage loan origination standards affecting, among other things, originator compensation, minimum repayment standards, and pre-payment penalties. The Dodd-Frank Act contained numerous other provisions affecting financial institutions of all types, many of which have an impact on our operating environment, including among other things, our regulatory compliance costs. However, the Dodd-Frank Act does not prevent states from adopting stricter consumer protection standards than those promulgated by the CFPB. State regulation of financial products and potential enforcement actions could also adversely affect the Company’s business, financial condition, or operations.

The EGRRCPA

In May 2018, the Economic Growth, Regulatory Reform, and Consumer Protection Act (“EGRRCPA”) was enacted, which, among other things, amended certain provisions of the Dodd-Frank Act as well as statutes administered by the FRB and the FDIC. The EGRRCPA provides targeted regulatory relief to financial institutions while preserving the existing framework under which U.S. financial institutions are regulated. The EGRRCPA relieves bank holding companies with less than $100 billion in assets, such as the Company, from the enhanced prudential standards imposed under Section 165 of the Dodd-Frank Act (including, but not limited to, resolution planning and enhanced liquidity and risk management requirements). Please see the section below titled Impacts of Growth for more information.

In addition to amending the Dodd Frank Act, the EGRRCPA also includes certain additional banking-related provisions, consumer protection provisions and securities law-related provisions. Many of the EGRRCPA’s changes were implemented through rules finalized by the federal banking agencies over the course of 2019. These rules and their enforcement are subject to the substantial regulatory discretion of the federal banking agencies.

Volcker Rule

Section 619 of the Dodd-Frank Act, commonly known as the “Volcker Rule,” restricts the ability of banking entities from: (i) engaging in “proprietary trading” and (ii) investing in or sponsoring certain covered funds, subject to certain limited exceptions. Under the Volcker Rule, the term “covered funds” is defined as any issuer that would be an investment company under the Investment Company Act but for the exemption in Section 3(c)(1) or 3(c)(7) of that Act. There are also several exemptions from the definition of covered fund, including, among other things, loan securitizations, joint ventures, certain types of foreign funds, entities issuing asset-backed commercial paper, and registered investment companies. The EGRRCPA and the subsequently promulgated inter-agency rules have aimed at simplifying and tailoring certain requirements related to the Volcker Rule.

Real Estate Lending Standards and Guidance

The federal regulatory agencies have adopted regulations setting forth standards for extensions of credit that are secured by real estate. Under these regulations, the Bank must adopt and maintain written policies establishing appropriate limits and standards for extensions of credit that are secured by real estate. These policies must establish loan portfolio diversification standards, prudent underwriting standards (including loan-to-value limits) that are clear and measurable, loan administration procedures and documentation, approval and reporting requirements.

The federal regulatory agencies have also jointly issued guidance on “Concentrations in Commercial Real Estate Lending,” which defines commercial real estate (“CRE”) loans as exposures secured by raw land, land development and construction (including 1-4 family residential construction), multi-family property, and non-farm nonresidential property where the primary or a significant source of repayment is derived from rental income or the proceeds of the sale, refinancing, or permanent financing of the property. The guidance requires that appropriate processes be in place to identify, monitor and control risks associated with real estate lending concentrations. If a concentration is present, management must employ heightened risk management practices that address key elements, including board and management oversight and strategic planning, portfolio management, development of underwriting standards, risk assessment and monitoring through market analysis and stress testing, and maintenance of increased capital levels as needed to support the level of CRE lending. The guidance states that the following metrics may indicate a concentration of CRE loans, but that these metrics are neither limits nor a safe harbor: (1) total reported loans for construction, land development, and other land represent 100% or more of total risk-based capital; or (2) total reported loans secured by multi-family properties, nonfarm non-residential properties (excluding those that are owner-occupied), and loans for construction, land development, and other land represent 300% or more of total risk-based capital and the bank’s CRE loan portfolio has increased 50% or more during the prior 36 months.

Brokered Deposits

Section 29 of the FDIA and the FDIC regulations promulgated thereunder limit the ability of any bank to accept, renew or roll over any brokered deposit unless it is well capitalized or, with the FDIC’s approval, adequately capitalized. However, as a result of the EGRRCPA, the FDIC has undertaken a comprehensive review of its regulatory approach to brokered deposits, including reciprocal deposits, and interest rate caps applicable to banks that are less than well capitalized. In December 2020, the FDIC issued a final rulemaking to modernize its brokered deposit regulations. Among other things, the final rule established a new framework for analyzing certain provisions of the “deposit broker” definition and established certain automatic “primary purpose” exemptions from the deposit broker definition, as well as revised certain interest rate restrictions that apply to less than well capitalized insured depository institutions. The final rule became effective April 1, 2021; and full compliance was required by January 1, 2022. Implementation of the final rule did not have a material impact on our subsidiary bank. In July 2024, the FDIC proposed significant revisions to the brokered deposit regulations, including significant expansions to the definition of “deposit broker,” and significantly narrowing the primary purpose exception to “deposit broker” status, but the FDIC withdrew the proposals during 2025.

FDIC Deposit Insurance and Assessments

Our customer deposit accounts are insured up to applicable limits by the FDIC’s Deposit Insurance Fund (“DIF”) up to $250,000 per separately insured depositor. Simmons Bank is required to pay deposit insurance assessments to maintain the DIF. Because Simmons Bank’s assets exceed $10 billion, its deposit insurance assessment is based on a scoring system that examines the institution’s supervisory ratings and certain financial measures. The scoring system assesses risk measures to produce two scores, a performance score and a loss severity score, that are combined and converted to an initial assessment rate. The FDIC has the ability to make discretionary adjustments to the total score based upon significant risk factors not adequately captured in the calculations.

As described above in the section titled Potential Enforcement Action for Bank Holding Companies and Banks, the FDIC may terminate deposit insurance upon a finding that an institution has engaged in unsafe and unsound practices, is in an unsafe or unsound condition to continue operations, or has violated any applicable law, regulation, rule, order or condition imposed by the FDIC.

14

In November 2023, the FDIC issued a final rule to implement a special assessment to recover losses to the DIF incurred as a result of recent bank failures and the FDIC’s use of the systemic risk exception to cover certain deposits that were otherwise uninsured. The special assessment was based on estimated uninsured deposits as of December 31, 2022 (excluding the first $5.0 billion) and will be assessed at an initial quarterly rate of 3.36 basis points, over eight quarterly assessment periods, beginning in the first quarter of 2024. As a result of this final rule, we accrued $12.4 million related to this assessment. Under the final rule, the estimated loss pursuant to the systemic risk determination will be periodically adjusted, and the FDIC has retained the ability to cease collection early, extend the special assessment collection period and impose a final shortfall special assessment on a one-time basis. The FDIC approved an interim final rule in 2025 to amend certain aspects of the FDIC’s collection activities, including, among other things, reducing the rate at which the special assessment will be charged in the eighth collection quarter from 3.36 basis points to 2.97 basis points.

Community Reinvestment Act

The Community Reinvestment Act of 1977 (“CRA”) requires that federal banking agencies evaluate the record of each financial institution in meeting the credit needs of the market areas they serve, including low and moderate-income individuals and communities. These activities are also considered in connection with, among other things, applications for mergers, acquisitions and the opening of a branch or facility, and negative results of these evaluations could prevent us from engaging in these types of transactions. Simmons Bank received a “satisfactory” CRA rating during its most recent exam.

UDAP and UDAAP

Federal laws, including Section 5 of the Federal Trade Commission Act, prohibit financial institutions from engaging in unfair or deceptive acts or practices (“UDAP”) in or affecting commerce. The Dodd-Frank Act expanded regulation in this space to apply to unfair, deceptive or abusive acts or practices (“UDAAP”) and delegated to the CFPB supervision and enforcement authority for UDAAP with respect to our subsidiary bank and rulemaking authority with respect to UDAAP. These laws have been used to, among other things, address certain problematic practices that may not fall directly within the scope of other banking or consumer protection laws.

Financial Privacy and Data Security

The Company is subject to federal laws, including the Gramm-Leach-Bliley Act of 1999 (“GLBA”), and certain state laws containing consumer privacy protection and data security provisions. These federal and state laws, and the rules and regulations promulgated thereunder, impose restrictions on our ability to disclose non-public information concerning consumers to nonaffiliated third parties. These laws, rules and regulations also mandate the distribution of privacy policies to consumers, as well as provide consumers an ability to prevent our disclosure of their information under certain circumstances.

In addition, the GLBA requires that financial institutions, such as our subsidiary bank, implement comprehensive written information security programs that include administrative, technical, and physical safeguards to protect consumer information and data. Further, pursuant to interpretive guidance issued under the GLBA and certain state laws, financial institutions are also generally required to notify customers of security breaches that result in unauthorized access to their nonpublic personal information.

The federal bank regulatory agencies also adopted rules to improve the sharing of information about cyber incidents that may affect the U.S. banking system. A banking organization must notify its primary federal regulator of certain significant “computer-security incidents” that may pose a threat to the stability of the U.S. financial sector as soon as possible and no later than 36 hours after the banking organization determines that a notification incident has occurred. A bank service provider must also notify affected banking organization customers as soon as possible when the provider determines that it has experienced a computer-security incident that has materially disrupted or degraded or is reasonably likely to materially disrupt or degrade covered services provided to such banking organization customers for four or more hours.

Although these laws and regulations impose compliance costs and create obligations and, in some cases, reporting obligations, and compliance with all of the laws, regulations, and reporting obligations may require significant resources of the Company and our subsidiary bank, these laws and regulations do not materially affect our products, services or other business activities.

Anti-Money Laundering and Anti-Terrorism

Simmons Bank is subject to the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 (also known as the “PATRIOT Act”), the Bank Secrecy Act (“BSA”) and rules and regulations of the Office of Foreign Assets Control (“OFAC”).

Under Title III of the PATRIOT Act, all financial institutions are required to take certain measures to identify their customers, prevent money laundering, monitor customer transactions, and report suspicious activity to U.S. law enforcement agencies. Financial institutions also are required to respond to requests for information from federal banking agencies and law enforcement agencies. Information sharing among financial institutions for the above purposes is encouraged by an exemption granted to complying financial institutions from the privacy provisions of the GLBA and other privacy laws.

Among other things, Simmons Bank is required to establish an anti-money laundering (“AML”) program which includes the designation of a BSA officer, the establishment and maintenance of BSA/AML training, the establishment and maintenance of BSA/AML policies and procedures, independent testing of the AML program, and compliance with customer due diligence requirements. Our subsidiary bank must also employ enhanced due diligence under certain conditions. Compliance with BSA/AML requirements is routinely examined by regulators, and failure of a financial institution to meet its requirements in combating AML and anti-terrorism activities could result in severe penalties for the institution, including, among other things, the inability to receive the requisite regulatory approvals for mergers and acquisition.

Further, OFAC administers economic sanctions imposed by the federal government that affect transactions with foreign countries, individuals, and others (as the “OFAC Rules”). The OFAC Rules target many countries as well as specially designated nationals and blocked persons (collectively, “SDNs”) and take many different forms. Blocked assets (property and bank deposits) that are associated with such countries and SDNs cannot be paid out, withdrawn, set off, or transferred in any manner without a license from OFAC. Failure to comply with the OFAC Rules can result in serious legal and reputational consequences.

In December 2020, the U.S. Congress enacted the National Defense Authorization Act (“NDAA”) that, among other provisions, made significant updates to the federal BSA/AML regulations that aim to eliminate the use of shell companies that facilitate the laundering of criminal proceeds. The NDAA includes the Corporate Transparency Act (“CTA”), which requires the U.S. Treasury Department’s Financial Crimes Enforcement Network (“FinCEN”) to, among other things, establish a national beneficial ownership information registry. In December 2021, FinCEN issued the first of three planned rules, which rule was adopted to implement a national beneficial ownership reporting framework. In September 2022, FinCEN issued the final Beneficial Ownership Information Reporting Requirements rule (“BOI Reporting Rule”), which requires certain “reporting companies” to file beneficial ownership information reports with FinCEN that will be stored in the national beneficial ownership registry and will detail the reporting company’s beneficial owners. In December 2023, FinCEN issued the second of the three planned rules, which rule was adopted to implement protocols for access to and disclosure of beneficial ownership information. In March 2025, FinCEN issued an interim final rule removing the requirement for U.S. companies and U.S. persons to report such beneficial ownership information and indicated that it would issue a modified set of regulations regarding beneficial ownership disclosures. Given the potential of new regulations from FinCEN, as well as ongoing litigation with respect to the CTA, it is not clear what impact the CTA and BOI Reporting Rule will have on the Bank. The Company and the Bank continue to monitor legislative, regulatory and supervisory developments related thereto.

Mortgage Banking Regulation

In connection with making mortgage loans, we are subject to rules and regulations that, among other things, establish standards for loan origination and servicing, prohibit discrimination, provide for inspections and appraisals of property, require credit reports on prospective borrowers, in some cases restrict certain loan features and fix maximum interest rates and fees, require the disclosure of certain basic information to mortgagors concerning credit and settlement costs, limit payment for settlement services to the reasonable value of the services rendered and require the maintenance and disclosure of information regarding the disposition of mortgage applications based on race, gender, geographical distribution and income level, and establish requirements for servicing mortgage loans including loan mitigation. We are also subject to rules and regulations that require the collection and reporting of significant amounts of information with respect to mortgage loans and borrowers. Our mortgage origination activities are subject to Regulation Z, which implements the Truth in Lending Act. Certain provisions of Regulation Z require creditors to make a reasonable and good faith determination based on verified and documented information that a consumer applying for a mortgage loan has a reasonable ability to repay the loan according to its terms.

Federal Home Loan Bank of Dallas

Simmons Bank is a member of the Federal Home Loan Bank (“FHLB”) of Dallas (“FHLB-Dallas”), which is one of 11 regional Federal Home Loan Banks that provide funding to their members for making housing loans as well as for affordable housing and community development loans. Each FHLB serves as a reserve, or central bank, for the members within its assigned region and makes loans to its members in accordance with policies and procedures established by the board of directors of that FHLB. As a member, Simmons Bank must purchase and maintain stock in FHLB-Dallas. At December 31, 2025, Simmons Bank’s total investment in FHLB-Dallas was $25.3 million.

Incentive Compensation

The Dodd-Frank Act requires the federal banking agencies and the SEC to establish joint regulations or guidelines prohibiting incentive-based payment arrangements at specified regulated entities, including the Company and our subsidiary bank, with at least $1 billion in total consolidated assets that encourage inappropriate risks by providing an executive officer, employee, director, or principal shareholder with excessive compensation, fees, or benefits that could lead to material financial loss to the entity. The federal banking agencies and the SEC most recently proposed such regulations in 2016, but the regulations have not yet been finalized. However, in late 2022, the SEC finalized a set of rules directing national securities exchanges to establish listing standards regarding clawbacks of incentive-based executive compensation, which listing standards became effective in 2023. Specifically, Nasdaq implemented listing standards that require listed companies to adopt clawback policies, or policies mandating the recovery of excess incentive compensation earned by a current or former executive officer during the three fiscal years preceding the date the listed company is required to prepare an accounting restatement, including to correct an error that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. We adopted a compensation recovery policy pursuant to the Nasdaq listing standards, and the policy is included as Exhibit 97 to this Annual Report on Form 10-K.

The Dodd-Frank Act also requires publicly traded companies to give stockholders a non-binding vote on executive compensation at least every three years and on so-called “golden parachute” payments in connection with approvals of mergers and acquisitions. The Company gives stockholders a non-binding vote on executive compensation annually.

Impacts of Growth

Because the Company and Simmons Bank have exceeded $10 billion in assets, each of the Company and the Bank are subject to heightened requirements (as compared to smaller community banking organizations) that are imposed by various federal banking law and regulations.

Among other things, the Dodd-Frank Act, through the Durbin Amendment, and associated Federal Reserve regulations cap the interchange rate on debit card transactions that can be charged by banks that, together with their affiliates, have at least $10 billion in assets at $0.21 per transaction plus five basis points multiplied by the value of the transaction (plus, for a debit card issuer that meets certain fraud-prevention standards, a “fraud-prevention adjustment” of $0.01 per transaction). The cap goes into effect July 1st of the year following the year in which a bank reaches the $10 billion asset threshold. Simmons Bank became subject to the interchange rate cap effective July 1, 2018. In October 2023, the Federal Reserve proposed lowering the maximum interchange fee, but the proposal has faced legal challenges, and the Company is monitoring developments related to the proposal and continuing to assess its potential impact.

As of December 31, 2017, the Company exceeded $15 billion in total assets and trust preferred securities are no longer included as Tier 1 capital. Trust preferred securities and qualifying subordinated debt are included as total Tier 2 capital.

The Dodd-Frank Act also previously required banks and bank holding companies with more than $10 billion in assets to adhere to certain enhanced prudential standards, including requirements to conduct annual stress tests, report the results to regulators and publicly disclose such results. However, as a result of regulatory reform finalized following passage of the EGRRCPA, the Company and Simmons Bank are no longer required to conduct an annual stress test of capital under the Dodd-Frank Act. Further, as a result of passage of the EGRRCPA, bank holding companies with less than $100 billion in assets, such as the Company, are exempt from the resolution planning, enhanced liquidity standards, and risk management requirements imposed under Section 165 of the Dodd-Frank Act. In anticipation of becoming subject to these requirements, the Company and Simmons Bank had begun the necessary preparations, including undertaking a gap analysis, implementing enhancements to the audit and compliance departments, and investing in various information technology systems. Notwithstanding that federal banking agencies will not take action with respect to these enhanced prudential standards, the Company and its subsidiary bank continue to review their capital planning and risk management practices in connection with the regular supervisory processes of the FRB.

17

Additionally, the Dodd-Frank Act established the CFPB and granted it supervisory authority over banks with total assets of more than $10 billion. Simmons Bank is subject to CFPB oversight with respect to its compliance with federal consumer financial laws. Simmons Bank continues to be subject to the oversight of its other regulators with respect to matters outside the scope of the CFPB’s jurisdiction. The CFPB has broad rule-making, supervisory, examination and enforcement authority, as well as expanded data collecting and enforcement powers, all of which impact the operations of Simmons Bank. The current leadership of the CFPB has indicated intentions to rescind or revise many regulations, as well as to narrow its enforcement and supervision. We cannot currently predict the nature and timing of future developments that may potentially impact CFPB rules, proposals, enforcement and supervision.

Future Legislation and Regulation

Because of concerns relating to, among other things, competitiveness and the safety and soundness of the banking industry, governmental administrations, as well as Congress and state legislatures, often consider a number of wide-ranging proposals for altering the structure, regulation, and competitive relationships of the nation’s financial institutions and of those chartered in a particular state legislature’s jurisdiction. We cannot predict the timing of any proposals or whether or in what form any proposals will be adopted or the extent to which our business, including our financial condition and results of operations, may be affected.

Effect of Governmental Monetary Policies

The FRB uses monetary policy tools to impact interest rates, credit market conditions and money market conditions, as well as to influence general economic conditions, including employment, market interest and inflation rates. These policies can have a significant impact on the absolute levels and distribution of deposits, loans and investment securities, as well as on market interest rates charged on loans or paid for deposits and other borrowings. Monetary policies of the FRB have in the past had a significant effect on the operating results of bank holding companies and their subsidiary banks, such as the Company and Simmons Bank, and may have similar effects in the future.
