Tyler, Texas (January 29, 2026) Southside Bancshares, Inc. (“Southside” or the “Company”) (NYSE: SBSI) today reported its financial results for the quarter and year ended December 31, 2025.

“During the fourth quarter, we continued the restructure of a portion of our available for sale (“AFS”) securities portfolio by selling approximately $82 million of lower yielding long duration municipal securities with a combined taxable equivalent yield of approximately 2.59% at a loss of $7.3 million,” stated Keith Donahoe, President and Chief Executive Officer of Southside. “All the sales occurred at the end of October. The proceeds from the sale of these securities were reinvested primarily in U.S. Agency mortgage-backed securities. Linked quarter, net interest income increased $1.5 million, our net interest margin increased four basis points to 2.98% due to lower funding costs during the quarter and deposits, net of public fund and brokered deposits, increased $40.8 million. Linked quarter, total loans increased $52.7 million. On February 15, 2026, we will redeem our $93 million subordinated notes due 2030 which bear interest at a rate of 7.51%. We expect the redemption to have a positive impact on our net interest margin in the first quarter.”

Operating Results for the Three Months Ended December 31, 2025

Net income was $21.0 million for the three months ended December 31, 2025, compared to $21.8 million for the same period in 2024, a decrease of $0.8 million, or 3.7%. Earnings per diluted common share were $0.70 for the three months ended December 31, 2025, compared to $0.71 for the same period in 2024, a decrease of $0.01, or 1.4%. The decrease in net income was due to the net loss on sale of AFS securities, partially offset by an increase in net interest income, decreases in income tax expense and provision for credit losses and increases in several noninterest income categories. For the three months ended December 31, 2025, we had a $7.3 million net loss on sale of AFS securities, compared to no gain or loss for the same period in 2024. Annualized returns on average assets and average shareholders’ equity for the three months ended December 31, 2025 were 0.99% and 9.85%, respectively, compared to 1.03% and 10.54%, respectively, for the three months ended December 31, 2024. Our efficiency ratio and tax-equivalent efficiency ratio(1) were 53.85% and 52.28%, respectively, for the three months ended December 31, 2025, compared to 56.08% and 54.00%, respectively, for the three months ended December 31, 2024, and 54.87% and 52.99%, respectively, for the three months ended September 30, 2025.

Net interest income for the three months ended December 31, 2025 was $57.2 million, an increase of $3.5 million, or 6.6%, compared to the same period in 2024. The increase in net interest income was primarily due to the decrease in the average rate paid on our interest bearing liabilities. Linked quarter, net interest income increased $1.5 million, or 2.7%, compared to $55.7 million for the three months ended September 30, 2025, due to a decrease in the average rate paid on our interest bearing liabilities and an increase in the average balance of our interest earning assets, partially offset by the decrease in the average yield of our interest earning assets.

Our net interest margin and tax-equivalent net interest margin(1) increased to 2.87% and 2.98%, respectively, for the three months ended December 31, 2025, compared to 2.70% and 2.83%, respectively, for the same period in 2024. Linked quarter, net interest margin and tax-equivalent net interest margin(1) increased from 2.81% and 2.94%, respectively, for the three months ended September 30, 2025.

Noninterest income, excluding the net losses on sales of AFS securities, was $12.9 million and $12.3 million for the three months ended December 31, 2025 and 2024, respectively, an increase of $0.6 million, or 5.0%. The increase was due to increases in trust fees, deposit services income, brokerage services income and bank owned life insurance (“BOLI”) income, partially offset by a decrease in other noninterest income. On a linked quarter basis, noninterest income, excluding the net losses on sales of AFS securities increased $0.5 million, or 4.0%, compared to the three months ended September 30, 2025, due primarily to increases in deposit services income, BOLI income and brokerage services income, partially offset by a decrease in other noninterest income during the three months ended December 31, 2025.

Noninterest expense decreased $0.7 million, or 1.8%, to $37.5 million for the three months ended December 31, 2025, compared to $38.2 million for the same period in 2024, primarily due to decreases in professional fees and other noninterest expense. On a linked quarter basis, noninterest expense decreased by $57,000, or 0.2%, compared to the three months ended September 30, 2025.

Income tax expense decreased $0.9 million, or 18.8%, for the three months ended December 31, 2025, compared to the same period in 2024. On a linked quarter basis, income tax expense increased $3.6 million, or 1,900.5%. Our effective tax rate (“ETR”) decreased to 15.3% for the three months ended December 31, 2025, compared to 17.6% for the three months ended December 31, 2024, and increased from 3.7% for the three months ended September 30, 2025. The lower ETR for the three months ended December 31, 2025 compared to the same period in 2024, was primarily a result of an increase in net tax-exempt income as a percentage of pre-tax income. On a linked quarter basis, the higher ETR was primarily due to the impact of the net loss on the sale of AFS securities of $24.4 million recorded during the third quarter of 2025 on our tax-exempt income as a percentage of pre-tax income as well as an increase in state income tax expense.

Operating Results for the Year Ended December 31, 2025

Net income was $69.2 million for the year ended December 31, 2025, compared to $88.5 million for the same period in 2024, a decrease of $19.3 million, or 21.8%. Earnings per diluted common share were $2.29 for the year ended December 31, 2025, compared to $2.91 for the same period in 2024, a decrease of $0.62, or 21.3%. The decrease in net income was driven by the net loss on the sale of AFS securities and, to a lesser extent, an increase in noninterest expense, partially offset by a decrease in income tax expense, increases in net interest income and several noninterest income categories and a decrease in provision for credit losses. For the year ended December 31, 2025, we had a $32.3 million net loss on sale of AFS securities, compared to a net loss of $2.5 million for the same period in 2024. Returns on average assets and average shareholders’ equity for the year ended December 31, 2025 were 0.83% and 8.40%, respectively, compared to 1.06% and 11.03%, respectively, for the year ended December 31, 2024. Our efficiency ratio and tax-equivalent efficiency ratio(1) were 55.32% and 53.48%, respectively, for the year ended December 31, 2025, compared to 55.69% and 53.52%, respectively, for the year ended December 31, 2024.

Net interest income was $221.1 million for the year ended December 31, 2025, compared to $216.1 million for the same period in 2024, an increase of $5.0 million, or 2.3%, due to decreases in the average rate paid on our interest bearing liabilities and a change in the mix of our interest earning assets and interest bearing liabilities, partially offset by the decrease in the average yield of interest earning assets.

Our net interest margin and tax-equivalent net interest margin(1) increased to 2.81% and 2.93%, respectively, for the year ended December 31, 2025, compared to 2.74% and 2.88%, respectively, for the same period in 2024.

Noninterest income, excluding the net losses on sale of AFS securities, was $48.2 million and $44.2 million for the years ended December 31, 2025 and 2024, respectively, an increase of $4.0 million, or 9.0%. The increase was primarily due to an increase in other noninterest income, trust fees, brokerage services income and gain on sale of loans, partially offset by a decrease in BOLI income.

Noninterest expense was $151.4 million for the year ended December 31, 2025, compared to $147.1 million for the same period in 2024, an increase of $4.2 million, or 2.9%. The increase was primarily due to increases in other noninterest expense, professional fees and advertising, travel and entertainment expense, partially offset by decreases in amortization of intangibles and communications expense.

Income tax expense decreased $5.5 million, or 29.0%, for the year ended December 31, 2025, compared to the same period in 2024. Our ETR was approximately 16.2% and 17.6% for the years ended December 31, 2025 and 2024, respectively. The lower ETR for the year ended December 31, 2025, as compared to the same period in 2024, was primarily a result of an increase in net tax-exempt income as a percentage of pre-tax income.

Linked quarter, loans increased $52.7 million, or 1.1%, due to increases of $29.0 million in construction loans, $24.1 million in commercial real estate loans and $14.8 million in commercial loans. These increases were partially offset by decreases of $6.6 million in municipal loans, $5.7 million in 1-4 family residential loans and $2.9 million in loans to individuals.

Securities at December 31, 2025 were $2.70 billion, a decrease of $109.4 million, or 3.9%, compared to $2.81 billion at December 31, 2024. Linked quarter, securities increased $147.9 million, or 5.8%, from $2.56 billion at September 30, 2025.

Deposits at December 31, 2025 were $6.87 billion, an increase of $210.9 million, or 3.2%, compared to $6.65 billion at December 31, 2024.

Linked quarter, deposits decreased $96.4 million, or 1.4%, from $6.96 billion at September 30, 2025, primarily due to the decrease of $223.5 million in brokered deposits, partially offset by increases of $86.3 million and $40.8 million in public fund deposits and retail deposits, respectively.

At December 31, 2025, we had 178,757 total deposit accounts with an average balance of $35,000. Our estimated uninsured deposits were 39.7% of total deposits as of December 31, 2025. When excluding affiliate deposits (Southside-owned deposits) and public fund deposits (all collateralized), our total estimated deposits without insurance or collateral was 23.0% as of December 31, 2025. Our noninterest bearing deposits represent approximately 20.9% of total deposits. Linked quarter, our cost of interest bearing deposits decreased nine basis points from 2.82% in the prior quarter to 2.73%. Linked quarter, our cost of total deposits decreased nine basis points from 2.25% in the prior quarter to 2.16%.

Our cost of total deposits decreased 13 basis points, from 2.36% for the year ended December 31, 2024, to 2.23% for the year ended December 31, 2025.

Capital Resources and Liquidity

Our capital ratios and contingent liquidity sources remain solid. During the fourth quarter ended December 31, 2025, we repurchased 369,804 shares of the Company’s common stock at an average price of $28.84 per share, pursuant to our Stock Repurchase Plan (the “Plan”). Under the Plan, repurchases of our outstanding common stock may be carried out in open market purchases, privately negotiated transactions or pursuant to any trading plan that might be adopted in accordance with Rule 10b5-1 of The Securities Exchange Act of 1934, as amended. The Company has no obligation to repurchase any shares under the Plan and may modify, suspend or discontinue the Plan at any time. As of December 31, 2025, approximately 0.8 million authorized shares remained available for purchase. We have not purchased any common stock pursuant to the Plan subsequent to December 31, 2025.

As of December 31, 2025, our total available contingent liquidity, net of current outstanding borrowings, was $2.78 billion, consisting of FHLB advances, Federal Reserve Discount Window and correspondent bank lines of credit.

Asset Quality

Nonperforming assets at December 31, 2025 were $38.2 million, or 0.45% of total assets, an increase of $2.6 million, or 7.4%, from $35.6 million, or 0.42% of total assets, at September 30, 2025, due primarily to an increase of $2.5 million in nonaccrual loans. The increase in nonaccrual loans compared to September 30, 2025 was due to a $3.4 million increase in 1-4 family real estate. Nonperforming assets increased $34.7 million, or 965.6%, compared to $3.6 million, or 0.04% of total assets, at December 31, 2024, due primarily to an increase of $27.5 million in restructured loans. The increase in restructured loans was due to the extension of maturity in the first quarter of 2025 on a $27.5 million commercial real estate loan to allow for an extended lease up period.

The allowance for loan losses totaled $45.1 million, or 0.94% of total loans, at December 31, 2025, compared to $45.3 million, or 0.95% of total loans, at September 30, 2025. The allowance for loan losses was $44.9 million, or 0.96% of total loans, at December 31, 2024. The decrease in allowance as a percentage of total loans compared to December 31, 2024 was primarily due to improvements in the overall economic forecast in the CECL model.

For the three months ended December 31, 2025, we recorded a provision for credit losses for loans of $0.6 million, compared to $1.6 million and $1.7 million for the three months ended December 31, 2024 and September 30, 2025, respectively. Net charge-offs were $0.8 million for the three months ended December 31, 2025, compared to net charge-offs of $1.0 million and $0.8 million for the three months ended December 31, 2024 and September 30, 2025, respectively. Net charge-offs were $2.8 million for the year ended December 31, 2025, compared to net charge-offs of $1.9 million for the year ended December 31, 2024.

We recorded a provision for credit losses on off-balance-sheet credit exposures of $17,000 for the three months ended December 31, 2025, compared to a reversal of provision of $0.2 million and $0.6 million for the three months ended December 31, 2024 and September 30, 2025, respectively. We recorded a provision for losses on off-balance-sheet credit exposures of $25,000 for the year ended December 31, 2025, compared to a reversal of provision for credit losses on off-balance-sheet credit exposures of $0.8 million for the year ended December 31, 2024. The balance of the allowance for off-balance-sheet credit exposures was $3.2 million and $3.1 million at December 31, 2025 and 2024, respectively, and is included in other liabilities.

Non-GAAP Financial Measures

Our accounting and reporting policies conform to generally accepted accounting principles (“GAAP”) in the United States and prevailing practices in the banking industry. However, certain non-GAAP measures are used by management to supplement the evaluation of our performance. These include the following fully taxable-equivalent measures (“FTE”): (i) Net interest income (FTE), (ii) net interest margin (FTE), (iii) net interest spread (FTE), and (iv) efficiency ratio (FTE), which include the effects of taxable-equivalent adjustments using a federal income tax rate of 21% to increase tax-exempt interest income to a tax-equivalent basis. Interest income earned on certain assets is completely or partially exempt from federal income tax. As such, these tax-exempt instruments typically yield lower returns than taxable investments.

Net interest income (FTE), net interest margin (FTE) and net interest spread (FTE). Net interest income (FTE) is a non-GAAP measure that adjusts for the tax-favored status of net interest income from certain loans and investments and is not permitted under GAAP in the consolidated statements of income. We believe that this measure is the preferred industry measurement of net interest income and that it enhances comparability of net interest income arising from taxable and tax-exempt sources. The most directly comparable financial measure calculated in accordance with GAAP is our net interest income. Net interest margin (FTE) is the ratio of net interest income (FTE) to average earning assets. The most directly comparable financial measure calculated in accordance with GAAP is our net interest margin. Net interest spread (FTE) is the difference in the average yield on average earning assets on a tax-equivalent basis and the average rate paid on average interest bearing liabilities. The most directly comparable financial measure calculated in accordance with GAAP is our net interest spread.

Efficiency ratio (FTE).  The efficiency ratio (FTE) is a non-GAAP measure that provides a measure of productivity in the banking industry. This ratio is calculated to measure the cost of generating one dollar of revenue. The ratio is designed to reflect the percentage of one dollar which must be expended to generate that dollar of revenue. We calculate this ratio by dividing noninterest expense, excluding amortization expense on intangibles and certain nonrecurring expense by the sum of net interest income (FTE) and noninterest income, excluding net gain (loss) on sale of securities available for sale and certain nonrecurring impairments. The most directly comparable financial measure calculated in accordance with GAAP is our efficiency ratio.

These non-GAAP financial measures should not be considered alternatives to GAAP-basis financial statements and other bank holding companies may define or calculate these non-GAAP measures or similar measures differently. Whenever we present a non-GAAP financial measure in an SEC filing, we are also required to present the most directly comparable financial measure calculated and presented in accordance with GAAP and reconcile the differences between the non-GAAP financial measure and such comparable GAAP measure.

Management believes adjusting net interest income, net interest margin and net interest spread to a fully taxable-equivalent basis is a standard practice in the banking industry as these measures provide useful information to make peer comparisons. Tax-equivalent adjustments are reflected in the respective earning asset categories as listed in the “Average Balances with Average Yields and Rates” tables.

A reconciliation of our non-GAAP financial measures to the comparable GAAP financial measures is included at the end of the financial statement tables.
