Simmons First National Corporation Reports Fourth Quarter 2024 Results

George Makris, Jr., Simmons’ Chairman and Chief Executive Officer, commented on the quarterly results:

Simmons’ fourth quarter results were encouraging as we head into 2025. Profitability trends improved and should be a good foundation from which to build. While we are cautiously optimistic as we enter the new year, we are also watching several factors that could impact us in 2025: a new administration and how its policies affect domestic growth; inflation and employment levels; the trajectory of short-term interest rates; regulatory changes and their effect on our operating costs and growth; insurance availability and costs for both commercial enterprises and consumers; and population migration’s effects on housing trends geographically.

I also want to recognize and thank the following leaders who retired from Simmons at the end of 2024: Bob Fehlman, Steve Massanelli, Steve Wade, Johnny McCaleb, and Pat Neely. These leaders have played a significant role in the growth of Simmons, and they will be missed. At the same time, I am excited about the next generation of leadership and the opportunities we see ahead.

Simmons First National Corporation (NASDAQ: SFNC) (Simmons or Company) today reported net income of $48.3 million for the fourth quarter of 2024, compared to $24.7 million in the third quarter of 2024 and $23.9 million in the fourth quarter of 2023. Diluted earnings per share were $0.38 for the fourth quarter of 2024, compared to $0.20 in the third quarter of 2024 and $0.19 in the fourth quarter of 2023. Adjusted earnings¹ for the fourth quarter of 2024 were $49.6 million, compared to $46.0 million in the third quarter of 2024 and $50.2 million in the fourth quarter of 2023. Adjusted diluted earnings per share¹ for the fourth quarter of 2024 were $0.39, compared to $0.37 in the third quarter of 2024 and $0.40 in the fourth quarter of 2023.

The table below summarizes the impact of certain items, consisting primarily of branch right sizing, early retirement, loss on sale of available-for-sale (AFS) investment securities and FDIC special assessments. They are also described in further detail in the “Reconciliation of Non-GAAP Financial Measures” tables contained in this press release.

Impact of Certain Items on Earnings and Diluted EPS

Net Interest Income

Net interest income for the fourth quarter of 2024 totaled $164.9 million, compared to $157.7 million in the third quarter of 2024 and $155.6 million in the fourth quarter of 2023. Interest income totaled $326.0 million for the fourth quarter of 2024, compared to $334.3 million in the third quarter of 2024 and $323.5 million in the fourth quarter of 2023. The decrease in interest income on a linked quarter basis was primarily driven by a decline in the level of interest rates resulting from interest rate cuts at the end of the third quarter and during the fourth quarter of 2024. Interest expense totaled $161.0 million for the fourth quarter of 2024, compared to $176.6 million in the third quarter of 2024 and $167.9 million in the fourth quarter of 2023. The decrease in interest expense was driven by lower interest rates, coupled with management’s ability to proactively manage deposit costs and reduced use of wholesale funding sources. Included in net interest income is accretion recognized on loans, which totaled $1.9 million in the fourth quarter of 2024, $1.5 million in the third quarter of 2024 and $1.8 million in the fourth quarter of 2023.

The yield on loans on a fully taxable equivalent (FTE) basis for the fourth quarter of 2024 was 6.32 percent, down 12 basis points from 6.44 percent for the third quarter of 2024 and up 12 basis points from 6.20 percent in the fourth quarter of 2023. Cost of deposits for the fourth quarter of 2024 was 2.60 percent, down 19 basis points from 2.79 percent for the third quarter of 2024 and up 2 basis points from 2.58 percent in the fourth quarter of 2023. The net interest margin on an FTE basis for the fourth quarter of 2024 was 2.87 percent, up 13 basis points from 2.74 percent for the third quarter of 2024 and up 19 basis points from 2.68 percent in the fourth quarter of 2023. The increase in net interest margin on a linked quarter basis was primarily due to lower deposits costs, as well as the reduced use of and rate paid on other borrowings.

Noninterest Income

Noninterest income for the fourth quarter of 2024 was $43.6 million, compared to $17.1 million in the third quarter of 2024 and $22.0 million in the fourth quarter of 2023. Included in the third quarter of 2024 and fourth quarter of 2023 was a $28.4 million and $20.2 million pre-tax loss on the sale of AFS investment securities, respectively. Excluding these items (which are described in the “Reconciliation of Non-GAAP Financial Measures” tables below), adjusted noninterest income¹ was $45.5 million for the third quarter of 2024 and $42.2 million in the fourth quarter of 2023. The decrease in adjusted noninterest income on a linked quarter basis was primarily due to a higher level of other noninterest income resulting from the gain on sale of other real estate recorded in the third quarter of 2024, offset in part by increases in most of our major fee-based businesses.

Noninterest Income

Noninterest Expense

Noninterest expense for the fourth quarter of 2024 was $141.1 million, compared to $137.2 million in the third quarter of 2024 and $148.1 million in the fourth quarter of 2023. Included in noninterest expense are certain items consisting of branch right sizing, early retirement and an FDIC special assessment. Collectively, these items totaled $1.8 million in the fourth quarter of 2024, $0.4 million in the third quarter of 2024 and $15.4 million in the fourth quarter of 2023. Excluding these items (which are described in the “Reconciliation of Non-GAAP Financial Measures” tables below), adjusted noninterest expense¹ was $139.3 million for the fourth quarter of 2024, $136.8 million in the third quarter of 2024 and $132.7 million in the fourth quarter of 2023. The increase in adjusted noninterest expense on a linked quarter basis was primarily due to seasonality in salaries and employee benefits.

Noninterest Expense

Loans and Unfunded Loan Commitments

Total loans at the end of the fourth quarter of 2024 were $17.0 billion, compared to $17.3 billion at the end of the third quarter of 2024 and $16.8 billion at the end of the fourth quarter of 2023. The decrease in total loans on a linked quarter basis was primarily due to normal seasonality in the company’s agricultural and mortgage warehouse loan portfolios, as well as further declines in a run-off portfolio consisting of small ticket equipment finance and acquired asset based lending portfolios (run-off portfolio). Unfunded loan commitments at the end of the fourth quarter of 2024 were $3.7 billion, up slightly from third quarter 2024 levels. The commercial loan pipeline ended the fourth quarter of 2024 at $1.3 billion and ready to close loans totaled $552 million, marking the second consecutive quarterly increase in both metrics.

Loans and Unfunded Loan Commitments

Deposits and Other Borrowings

Total deposits at the end of the fourth quarter of 2024 were $21.9 billion, down slightly from third quarter 2024 levels. The decrease in deposits on a linked quarter basis was primarily due to a decline in time deposits and brokered deposits, offset in part by increases in interest bearing transaction accounts (checking, money market and savings accounts) and public fund deposits. Other borrowings totaled $1.1 billion at the end of the fourth quarter of 2024, compared to $1.5 billion at the end of the third quarter of 2024 and $1.4 billion at the end of the fourth quarter of 2023. The decrease in other borrowing both on a linked quarter and year-over-year basis was primarily due to lower levels of FHLB advances.

Deposits

Asset Quality

Provision for credit losses totaled $13.3 million for the fourth quarter of 2024, compared to $12.1 million in the third quarter of 2024 and $10.0 million in the fourth quarter of 2023. Provision for credit losses on loans exceeded net charge-offs by $1.8 million during the fourth quarter of 2024. The allowance for credit losses on loans at the end of the fourth quarter of 2024 was $235.0 million, compared to $233.2 million at the end of the third quarter of 2024 and $225.2 million at the end of the fourth quarter of 2023. The increase in the allowance for credit losses on loans on a linked quarter basis and year-over-year basis reflected continued normalization of the credit environment, macroeconomic conditions and activity in the loan portfolio. The allowance for credit losses on loans was 1.38 percent at the end of the fourth quarter of 2024, compared to 1.35 percent at the end of the third quarter of 2024 and 1.34 percent at the end of the fourth quarter of 2023.

Net charge-offs as a percentage of average loans for the fourth quarter of 2024 were 27 basis points, compared to 22 basis points in the third quarter of 2024 and 11 basis points in the fourth quarter of 2023. Net charge-offs in the fourth quarter of 2024 included $2.5 million of charge-offs associated with the run-off portfolio. Net charge-offs from the run-off portfolio accounted for 6 basis points of total net charge-offs during the fourth quarter and 9 basis points of total net charge-offs during the third quarter of 2024.

Total nonperforming loans at the end of the fourth quarter of 2024 were $110.7 million, compared to $101.7 million at the end of the third quarter of 2024 and $84.5 million at the end of the fourth quarter of 2023. The increase in nonperforming loans on a linked quarter basis was primarily due to increases from the real estate construction and real estate 1-4 family loan portfolios. The nonperforming loan coverage ratio ended the fourth quarter of 2024 at 212 percent, compared to 229 percent at the end of the third quarter of 2024 and 267 percent at the end of the fourth quarter of 2023. Total nonperforming assets as a percentage of total assets were 45 basis points at the end of the fourth quarter of 2024, compared to 38 basis points at the end of the third quarter of 2024 and 33 basis points at the end of the fourth quarter of 2023. The increase in nonperforming assets as a percentage of total assets on a linked quarter basis was primarily due to an increase in nonperforming loans and an increase in other nonperforming assets resulting from the addition of two foreclosed properties.

Capital

Total stockholders’ equity at the end of the fourth quarter of 2024 was $3.5 billion, up slightly from the end of the third quarter 2024 and up $102.4 million from $3.4 billion at the end of the fourth quarter of 2023. The increase on a year-over-year basis was primarily due to an increase of $47.3 million in retained earnings, coupled with a $43.5 million recapture of accumulated other comprehensive income principally associated with the mark-to-market adjustment on AFS investment securities. Book value per share at the end of the fourth quarter of 2024 was $28.08, compared to $28.11 at the end of the third quarter of 2024 and $27.37 at the end of the fourth quarter of 2023.

Tangible common equity as a percentage of tangible assets¹ at the end of the fourth quarter of 2024 was 8.3 percent, compared to 8.2 percent at the end of the third quarter of 2024 and 7.7 percent at the end of the fourth quarter of 2023. Each of the regulatory capital ratios for Simmons and its lead subsidiary, Simmons Bank, continue to significantly exceed “well-capitalized” regulatory guidelines.

Share Repurchase Program

During the fourth 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 December 31, 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, noninterest income, and noninterest 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, early retirement program, 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 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.
