These results included strong revenue growth – notably with net interest margin expansion of 31 basis points to 3.81 percent – and continued expense discipline that resulted in a 19 percent linked-quarter increase in adjusted PPNR 1 . Adjusted ROAA 1 was 1.29 percent, and our adjusted efficiency ratio 1 improved to 53.6 percent. At the same time, balance sheet growth was solid as total loans increased 7 percent on an annualized basis and customer deposits increased 8 percent annualized. Our strong top-line performance in the quarter was coupled with improving credit quality and capital metrics. Nonperforming loans decreased 26 basis points to 0.64 percent of total loans with the charge-offs of two previously disclosed credit relationships and the sale of a run-off portfolio. In addition, we performed a deep dive analysis of nonperforming loans and took aggressive action to improve the loss content of the portfolio. Our reserves on these relationships were appropriate, and the ACL ended the quarter at 1.28 percent and is near the top-end of our modeled range. As we enter 2026, our commitment to delivering profitable growth and efficient scale positions us well for the future. We are confident in our ability to build on our momentum, driving value for our customers and associates and generating attractive returns for our shareholders. Simmons First National Corporation (NASDAQ: SFNC ) (Simmons or Company) today reported net income of $78.1 million for the fourth quarter of 2025, compared to a net loss of $562.8 million for the third quarter of 2025 and net income of $48.3 million for the fourth quarter of 2024. Diluted earnings per share were $0.54 for the fourth quarter of 2025, $(4.00) for the third quarter of 2025 and $0.38 for the fourth quarter of 2024. Adjusted earnings 1 for the fourth quarter of 2025 were $79.0 million, compared to $64.9 million in the third quarter of 2025 and $49.6 million in the fourth quarter of 2024. For the fourth quarter of 2025, return on average assets was 1.28 percent and return on average common equity was 9.08 percent. Adjusted return on average assets 1 was 1.29 percent and adjusted return on average tangible common equity 1 was 16.10 percent. As previously disclosed, during the third quarter of 2025, the Company utilized the net proceeds from a public offering of the Company's Class A common stock to support a balance sheet repositioning that included the sale of low-yielding investment securities and resulted in an after-tax loss of approximately $626 million. The table below summarizes the impact of the loss on the sale of securities, as well as other certain items, consisting primarily of loss on sale of equipment finance business, branch right sizing costs, early retirement program costs and a loss on early extinguishment of debt. These items are also described in further detail in the "Reconciliation of Non-GAAP Financial Measures" tables contained in this press release.

The increase in net interest income on a linked quarter basis was primarily driven by a $16.5 million decrease in interest expense, fueled by $14.1 million decrease in interest bearing deposit costs and a $2.4 million decrease in the cost of other interest bearing liabilities. Net interest margin for the fourth quarter of 2025 on a fully taxable equivalent basis was 3.81 percent, up 31 basis points compared to 3.50 percent for the third quarter of 2025 and up 94 basis points compared to 2.87 percent for the fourth quarter of 2024. The increase in net interest margin on a linked quarter basis reflects a full quarter impact of the balance sheet repositioning completed in the third quarter of 2025, coupled with strong loan and low-cost deposit growth during the fourth quarter of 2025.

Excluding these items (which are described in the "Reconciliation of Non-GAAP Financial Measures" tables below), adjusted noninterest income 1 was $45.9 million in the third quarter of 2025. The increase in adjusted noninterest income on a linked quarter basis was primarily driven by an increase in swap fee income, wealth management fees, debit and credit card fees, and proceeds from bank owned life insurance death benefits, which is included in other income in the table below.

Excluding these items (which are described in the "Reconciliation of Non-GAAP Financial Measures" tables below), adjusted noninterest expense 1 was $138.6 million in the fourth quarter of 2025, $139.7 million in the third quarter of 2025 and $139.3 million in the fourth quarter of 2024. The decrease in adjusted noninterest expense on a linked quarter basis primarily reflected salary and employee benefits accrual adjustments and a fraud recovery, offset in part by an increase in other operating expenses primarily related to the timing of certain professional services and marketing expenses recorded in the fourth quarter of 2025.

The increase in total loans was driven by increases in real estate – commercial, commercial and consumer & other portfolios, offset in part by seasonal declines in mortgage warehouse and agricultural portfolios. Unfunded loan commitments at the end of the fourth quarter of 2025 were $3.9 billion, compared to $4.0 billion at the end of the third quarter of 2025. The commercial loan pipeline totaled $1.5 billion at the end of the fourth quarter of 2025, and ready to close commercial loans totaled $774 million with a weighted average rate of 6.53 percent.

The increase in total deposits on a linked quarter basis was fueled by a $349 million, or 8 percent annualized, increase in customer deposits, driven by increases in interest bearing transaction accounts and savings accounts and interest bearing public fund deposits. The decrease in total deposits on a year-over-year basis deposits reflects a reduction of higher rate, non-relationship wholesale and public fund deposits as part of the balance sheet repositioning completed during the third quarter of 2025. Other borrowings at the end of the fourth quarter of 2025 were $302.3 million, compared to $18.8 million at the end of the third quarter of 2025 and $745.4 million at the end of the fourth quarter of 2024. The decrease in other borrowings on a year-over-year basis reflected the pay down of higher cost wholesale funding, primarily FHLB advances, as part of the balance sheet repositioning.

The decrease in nonperforming loans on a linked quarter basis reflected a $40.8 million decline related to two previously disclosed credit relationships. In addition, during the fourth quarter of 2025 the Company completed the sale of a small ticket equipment finance portfolio that was included in a run-off portfolio, resulting in a $3.2 million decrease in nonperforming loans. The nonperforming loan coverage ratio ended the fourth quarter of 2025 at 199 percent, compared to 168 percent at the end of the third quarter of 2025 and 212 percent at the end of the fourth quarter of 2024. Total nonperforming assets as a percentage of total assets were 51 basis points at the end of the fourth quarter of 2025, compared to 66 basis points at the end of the third quarter of 2025 and 45 basis points at the end of the fourth quarter of 2024. Net charge offs as a percentage of average loans for the fourth quarter of 2025 were 112 basis points and included net charge-offs of $28.2 million (or 65 basis points) related to the two previously disclosed credit relationships for which the Company held specific reserves totaling $30.8 million. In addition, there were $6.2 million (or 14 basis points) of net charge-offs related to a run-off portfolio that included a small ticket equipment finance portfolio that was sold during the quarter. Provision for credit losses on loans totaled $15.1 million for the fourth quarter of 2025, compared to $15.2 million in the third quarter of 2025 and $13.3 million in the fourth quarter of 2024. The allowance for credit losses on loans at the end of the fourth quarter of 2025 was $224.4 million, compared to $258.0 million at the end of the third quarter of 2025 and $235.0 million at the end of the fourth quarter of 2024. The allowance for credit losses on loans as a percentage of total loans (ACL ratio) was 1.28 percent at the end of the fourth quarter of 2025, compared to 1.50 percent at the end of the third quarter of 2025 and 1.38 percent at the end of the fourth quarter of 2024. The linked quarter reduction in the ACL ratio was primarily due to the utilization of specific reserves related to the two previously disclosed credit relationships and the run-off portfolio.

Tangible book value per share 1 at the end of the fourth quarter of 2025 was $13.91, compared to $16.80 at the end of the fourth quarter of 2024. The increase in book value per share and tangible book value per share on a linked quarter basis was primarily due to a $47.3 million increase in undivided profits. The year-over-year decline in book value per share and tangible book value per share was primarily due to an increase in outstanding shares resulting from the public offering of the Company's Class A common stock completed in the third quarter of 2025 and the impacts of the balance sheet repositioning. Total stockholders' equity as a percentage of total assets at the end of the fourth quarter of 2025 was 13.9%, unchanged from third quarter of 2025 levels and up from 13.1 percent at the end of the fourth quarter of 2024.

Non-GAAP Financial Measures This press release contains financial information determined by methods other than in accordance with U.S. generally accepted accounting principles (GAAP). The Company's management uses these non-GAAP financial measures in their analysis of the Company's performance. These measures adjust GAAP performance measures to, among other things, include the tax benefit associated with revenue items that are tax-exempt, as well as exclude from net income (including on a per share diluted basis), pre-tax, pre-provision earnings, net charge-offs, income available to common shareholders, noninterest income, and noninterest expense certain income and expense items attributable to, for example, losses on sale of securities, loss on sale of equipment finance business, net branch right-sizing initiatives, early retirement program, termination of vendor and software services and losses on early extinguishment of debt. In addition, the Company also presents certain figures based on tangible common stockholders' equity, tangible assets and tangible book value, which exclude goodwill and other intangible assets. The Company further presents certain figures that are exclusive of the impact of deposits and/or loans acquired through acquisitions, mortgage warehouse loans, and/or energy loans, or gains and/or losses on the sale of securities. The Company's management believes that these non-GAAP financial measures are useful to investors because they, among other things, present the results of the Company's ongoing operations without the effect of mergers or other items not central to the Company's ongoing business, as well as normalize for tax effects and certain other effects. Management, therefore, believes presentations of these non-GAAP financial measures provide useful supplemental information that is essential to a proper understanding of the operating results of the Company's ongoing businesses, and management uses these non-GAAP financial measures to assess the performance of the Company's ongoing businesses as related to prior financial periods. These non-GAAP disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the tables of this release.

Various factors, including, but not limited to, changes in economic conditions, changes in credit quality, changes in interest rates and related governmental policies, the effects of a government shutdown, changes in loan demand, changes in deposit flows, changes in real estate values, changes in the assumptions used in making the forward-looking statements, changes in the securities markets generally or the price of Simmons' common stock specifically, changes in information technology affecting the financial industry, and changes in customer behaviors, including consumer spending, borrowing, and saving habits; changes in tariff policies; general economic and market conditions; changes in governmental administrations; market disruptions including pandemics or significant health hazards, severe weather conditions, natural disasters, terrorist activities, financial crises, political crises, war and other military conflicts (including the ongoing military conflicts in the Middle East and between Russia and Ukraine) or other major events, or the prospect of these events; the soundness of other financial institutions and any indirect exposure related to the closings of other financial institutions and their impact on the broader market through other customers, suppliers and partners, or that the conditions which resulted in the liquidity concerns experienced by closed financial institutions may also adversely impact, directly or indirectly, other financial institutions and market participants with which the Company has commercial or deposit relationships; increased inflation; the loss of key employees; increased competition in the markets in which the Company operates and from non-bank financial institutions; increased unemployment; labor shortages; claims, damages, and fines related to litigation or government actions; changes in accounting principles relating to loan loss recognition (current expected credit losses); fraud that results in material losses or that we have not discovered yet that may result in material losses; the Company's ability to manage and successfully integrate its mergers and acquisitions and to fully realize cost savings and other benefits associated with acquisitions; increased delinquency and foreclosure rates on commercial real estate loans; significant increases in nonaccrual loan balances; cyber or other information technology threats, attacks or events; reliance on third parties for key services; government legislation; and other factors, many of which are beyond the control of the Company, could cause actual results to differ materially from those projected in or contemplated by the forward-looking statements. In addition, there can be no guarantee that the board of directors (Board) of Simmons will approve a quarterly dividend in future quarters, and the timing, payment, and amount of future dividends (if any) is subject to, among other things, the discretion of the Board and may differ significantly from past dividends.
