Simmons First National Corporation Reports Third Quarter 2024 Results

Bob Fehlman, Simmons’ Chief Executive Officer, commented on third quarter 2024 results:

Simmons’ third quarter results were highlighted by positive underlying trends across the board. Net interest income increased 10 percent annualized on a linked quarter basis as loan yields continued to increase, while deposit costs were unchanged from second quarter 2024 levels and appear to have peaked.

We also were proactive in responding to favorable market conditions when opportunities presented themselves. During the quarter, we decided to sell certain lower yielding bonds in our securities portfolio to hasten the pace of our ongoing balance sheet optimization strategy. While the loss on the sale of these securities weighed on reported results, on an adjusted basis total revenue, noninterest income and pre-provision net revenue posted solid growth on a linked quarter basis. Equally important, credit trends remained steady in the quarter and our allowance for credit losses on loans ended the quarter at 1.35 percent.

As we enter the final quarter of 2024, we believe our strong capital and liquidity positions combined with the liability sensitivity position of our balance sheet will provide tailwinds as we navigate an uncertain macroeconomic environment.

Simmons First National Corporation (NASDAQ: SFNC) (Simmons or Company) today reported net income of $24.7 million for the third quarter of 2024, compared to $40.8 million in the second quarter of 2024 and $47.2 million in the third quarter of 2023. Diluted earnings per share were $0.20 for the third quarter of 2024, compared to $0.32 in the second quarter of 2024 and $0.37 in the third quarter of 2023. Adjusted earnings¹ for the third quarter of 2024 were $46.0 million, compared to $41.9 million in the second quarter of 2024 and $48.8 million in the third quarter of 2023. Adjusted diluted earnings per share¹ for the third quarter of 2024 were $0.37, compared to $0.33 in the second quarter of 2024 and $0.39 in the third quarter of 2023.

During the third quarter of 2024, given prevailing market conditions, we executed a strategic decision to sell approximately $252 million of available-for-sale (AFS) investment securities with a weighted average yield of approximately 1.29 percent, resulting in an after-tax loss of $21.0 million. The proceeds from the sale were used to pay off higher rate wholesale funding consisting of Federal Home Loan Bank advances. The table below summarizes the impact of this transaction, along with the impact of certain other items consisting primarily of branch right sizing, early retirement, and termination of vendor and software services. They are also described in further detail in the “Reconciliation of Non-GAAP Financial Measures” tables contained in this press release.

Net Interest Income

Net interest income for the third quarter of 2024 totaled $157.7 million, compared to $153.9 million in the second quarter of 2024 and $153.4 million in the third quarter of 2023. Interest income totaled $334.3 million in the third quarter of 2024, compared to $329.1 million in the second quarter of 2024 and $310.3 million in the third quarter of 2023. The increase in interest income was primarily driven by an increase in total loans, coupled with an increase in the rate earned on loans. Interest expense totaled $176.6 million in the third quarter of 2024, up $1.3 million on a linked quarter basis primarily due to an increase in other borrowings costs, offset in part by a decrease in the interest expense on interest bearing deposits. Included in net interest income is accretion recognized on loans, which totaled $1.5 million in the third quarter of 2024, $1.6 million in the second quarter of 2024 and $2.1 million in the third quarter of 2023.

The yield on loans on a fully taxable equivalent (FTE) basis for the third quarter of 2024 was 6.44 percent, up 5 basis points from the 6.39 percent for the second quarter of 2024 and up 36 basis points from the 6.08 percent for the third quarter of 2023. Cost of deposits for the third quarter of 2024 was 2.79 percent, unchanged from second quarter 2024 levels. The net interest margin on an FTE basis for the third quarter of 2024 was 2.74 percent, compared to 2.69 percent for the second quarter of 2024 and 2.61 percent for the third quarter of 2023. The 5 basis point increase in the net interest margin on a linked quarter basis included an estimated 3 basis point benefit from the strategic sale of

AFS investment securities.

Noninterest Income

Noninterest income for the third quarter of 2024 was $17.1 million, compared to $43.3 million in the second quarter of 2024 and $42.8 million in the third quarter of 2023. Included in the third quarter of 2024 was a $28.4 million pre-tax loss on the strategic sale of AFS investment securities. Excluding this item, adjusted noninterest income¹ was $45.5 million in the third quarter of 2024, compared to $43.3 million in the second quarter of 2024 and $42.8 million in the third quarter of 2023. The increase in adjusted noninterest income on a linked quarter basis was primarily due to an increase in other noninterest income reflecting gains on the sale of other real estate owned.

Noninterest Expense

Noninterest expense for the third quarter of 2024 was $137.2 million, compared to $139.4 million in the second quarter of 2024 and $132.0 million in the third quarter of 2023. Included in noninterest expense are certain items consisting of branch right sizing, early retirement, and termination of vendor and software services, amongst others. Collectively, these items totaled $0.4 million in the third quarter of 2024, $1.5 million in the second quarter of 2024 and $2.1 million in the third quarter of 2023. Excluding these items (which are described in the “Reconciliation of Non-GAAP Financial Measures” tables below), adjusted noninterest expense¹ was $136.8 million in the third quarter of 2024, $137.8 million in the second quarter of 2024 and $129.9 million in the third quarter of 2023. The decrease in noninterest expense and adjusted noninterest expense on a linked quarter basis was primarily attributable to a decline in salaries and employee benefits reflecting incentive compensation accrual adjustments.

Loans and Unfunded Loan Commitments

Total loans at the end of the third quarter of 2024 were $17.3 billion, up $564.2 million, or 3 percent, compared to $16.8 billion at the end of the third quarter of 2023. Total loans on a linked quarter basis increased $143.6 million, or 3 percent on an annualized basis. Unfunded loan commitments at the end of the third quarter of 2024 were $3.7 billion, down slightly from second quarter 2024 levels. The commercial loan pipeline ended the third quarter of 2024 at $1.2 billion, compared to $1.0 billion at the end of the second quarter of 2024 and $877 million at the end of the third quarter of 2023.

Deposits

Total deposits at the end of the third quarter of 2024 were $21.9 billion, compared to $21.8 billion at the end of the second quarter of 2024 and $22.2 billion at the end of the third quarter of 2023. The increase in total deposits on a linked quarter basis was primarily attributable to an increase in public funds and brokered deposits. During the third quarter of 2024, the brokered deposit market reflected more favorable pricing opportunities compared to other wholesale funding options. As a result, while the utilization of brokered deposits increased during the third quarter of 2024, other borrowings totaled $1.0 billion, down $300.5 million on a linked quarter basis. The loan to deposit ratio at the end of the third quarter of 2024 was 79 percent, unchanged from second quarter 2024 levels.

Asset Quality

Provision for credit losses totaled $12.1 million for the third quarter of 2024, compared to $11.1 for the second quarter of 2024 and $7.7 million for the third quarter of 2023. Provision for credit losses on loans exceeded net charge-offs by $2.8 million during the third quarter of 2024. The allowance for credit losses on loans at the end of the third quarter of 2024 was $233.2 million, compared to $230.4 million at the end of the second quarter of 2024 and $218.5 million at the end of the third quarter of 2023. The increase in allowance for credit losses on loans on a linked quarter and year-over-year basis reflected normalization of the credit environment from historical lows, as well as changes in the macroeconomic conditions and increased activity in the loan portfolio. The allowance for credit losses on loans as a percentage of total loans was 1.35 percent at the end of the third quarter of 2024, compared to 1.34 percent at the end of the second quarter of 2024 and 1.30 percent at the end of the third quarter of 2023.

Net charge-offs as a percentage of average loans for the third quarter of 2024 were 22 basis points, compared to 19 basis points in the second quarter of 2024 and 28 basis points in the third quarter of 2023. Net charge-offs in the third quarter of 2024 included $3.5 million of charge-offs associated with the run-off portfolio, which consists of an acquired asset-based lending portfolio and a small ticket equipment finance portfolio. Net charge-offs from the run-off portfolio accounted for 9 basis points of total net charge-offs during the third quarter of 2024 and 16 basis points of total net charge-offs during the second quarter of 2024.

Total nonperforming loans at the end of the third quarter of 2024 were $101.7 million, compared to $103.4 million at the end of the second quarter of 2024 and $81.9 million at the end of the third quarter of 2023. The decrease in nonperforming loans on a linked quarter basis reflected $5 million of payoffs from the run-off portfolio and the previously noted charge-offs associated with this portfolio. The nonperforming loan coverage ratio ended the third quarter of 2024 at 229 percent, compared to 223 percent at the end of the second quarter of 2024 and 267 percent at the end of the third quarter of 2023. Total nonperforming assets as a percentage of total assets were 38 basis points at the end of the third quarter of 2024, compared to 39 basis points at the end of the second quarter of 2024 and 32 basis points at the end of the third quarter of 2023.

Capital

Total stockholders’ equity at the end of the third quarter of 2024 was $3.5 billion, compared to $3.3 billion at the end of the third quarter of 2023. On a linked quarter basis, total stockholders’ equity increased $70.0 million, primarily as a result of a $69.6 million recapture of accumulated other comprehensive income principally associated with mark-to-market adjustment on AFS investment securities. Book value per share at the end of the third quarter of 2024 was $28.11, up 2 percent on a linked quarter basis and up 7 percent compared to the end of the third quarter of 2023. Tangible book value per share¹ at the end of the third quarter of 2024 was $16.78, up 4 percent on a linked quarter basis and up 14 percent compared to the end of the third quarter of 2023.

Total stockholders’ equity as a percentage of total assets at September 30, 2024 was 12.9 percent, up from 12.6 percent reported at the end of the second quarter of 2024 and up from 11.9 percent reported at the end of the third quarter of 2023. Tangible common equity as a percentage of tangible assets¹ was 8.2 percent, up from 7.8 percent reported at the end of the second quarter of 2024 and up from 7.1 percent reported at the end of the third quarter of 2023. Each of the regulatory capital ratios for Simmons and its lead subsidiary, Simmons Bank, continue to significantly exceed “well-capitalized” guidelines.

Share Repurchase Program

During the third quarter of 2024, Simmons did not repurchase shares under its stock repurchase program that was authorized in January 2024 (2024 Program), which replaced its former repurchase program that was authorized in January 2022. Remaining authorization under the 2024 Program as of September 30, 2024, was approximately $175 million. The timing, pricing and amount of any repurchases under the 2024 Program will be determined by Simmons’ management at its discretion based on a variety of factors including, but not limited to, market conditions, trading volume and market price of Simmons’ common stock, Simmons’ capital needs, Simmons’ working capital and investment requirements, other corporate considerations, economic conditions, and legal requirements. The 2024

Program does not obligate Simmons to repurchase any common stock and may be modified, discontinued or suspended at any time without prior notice.

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, non-interest income, and non-interest expense certain income and expense items attributable to, for example, merger activity (primarily including merger-related expenses), gains and/or losses on sale of branches, net branch right-sizing initiatives, FDIC special assessment charges and gain/loss on the sale of AFS investment securities. The Company has updated its calculation of certain non-GAAP financial measures to exclude the impact of gains or losses on the sale of AFS investment securities in light of the impact of the Company’s strategic AFS investment securities transactions during the fourth quarter of 2023 and has presented past periods on a comparable basis.

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.

These forward-looking statements, including, without limitation, statements made in Mr. Fehlman’s quote, may be identified by reference to future periods or by the use of forward-looking terminology, such as “believe,” “budget,” “expect,” “foresee,” “anticipate,” “intend,” “indicate,” “target,” “estimate,” “plan,” “project,” “continue,” “contemplate,”

“positions,” “prospects,” “predict,” or “potential,” by future conditional verbs such as “will,” “would,” “should,” “could,” “might” or “may,” or by variations of such words or by similar expressions.

Any forward-looking statement speaks only as of the date of this press release, and Simmons undertakes no obligation to update these forward-looking statements to reflect events or circumstances that occur after the date of this press release. By nature, forward-looking statements are based on various assumptions and involve inherent risk and uncertainties. Various factors, including, but not limited to, changes in economic conditions, changes in credit quality, changes in interest rates and related governmental policies, 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; 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 between Russia and Ukraine and between Israel and Hamas) 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); 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; cyber 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. Additional information on factors that might affect the Company’s financial results is included in the Company’s Form 10-K for the year ended December 31, 2023, and other reports that the Company has filed with or furnished to the U.S. Securities and Exchange Commission (the SEC), all of which are available from the SEC on its website, www.sec.gov. 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.
