Quarterly Report for Quarter Ending September 30, 2026 (Form 10-Q)
MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
The following is a discussion of our consolidated financial condition, changes in our financial condition and results of our operations, and should be read and reviewed in conjunction with the financial statements, and the notes thereto, in this Quarterly Report on Form 10-Q, and in our 2025 Form 10-K. Certain risks, uncertainties and other factors, including those set forth under "Risk Factors" in Part I, Item 1A. of the 2025 Form 10-K and elsewhere in this Quarterly Report on Form 10-Q, may cause actual results to differ materially from the results discussed in the forward-looking statements appearing in this discussion and analysis.
Forward-Looking Statements
Certain statements of other than historical fact that are contained in this report may be considered to be "forward-looking statements" within the meaning of and subject to the safe harbor protections of the Private Securities Litigation Reform Act of 1995. These forward-looking statements are not guarantees of future performance, nor should they be relied upon as representing management's views as of any subsequent date. These statements may include words such as "expect," "estimate," "project," "anticipate," "appear," "believe," "could," "should," "may," "might," "will," "would," "seek," "intend," "probability," "risk," "goal," "target," "objective," "plans," "potential," and similar expressions. Forward-looking statements are statements with respect to our beliefs, plans, expectations, objectives, goals, anticipations, assumptions, estimates, intentions and future performance and are subject to significant known and unknown risks and uncertainties, which could cause our actual results to differ materially from the results discussed in the forward-looking statements. For example, trends in asset quality, capital, liquidity, our ability to sell nonperforming assets, expense reductions, planned operational efficiencies and earnings from growth and certain market risk disclosures, including the impact of interest rates and our expectations regarding rate changes, tax reform, inflation, the impacts related to or resulting from other economic factors are based upon information presently available to management and are dependent on choices about key model characteristics and assumptions and are subject to various limitations. By their nature, certain of the market risk disclosures are only estimates and could be materially different from what actually occurs in the future. Accordingly, our results could materially differ from those that have been estimated. The most significant factors that could cause future results to differ materially from those anticipated by our forward-looking statements include general economic conditions in our markets, including higher energy and gas prices, the impact of changes in interest rates on our financial projections, models and guidance, as well as the effects of declines in the real estate market, tariffs or trade wars (including reduced consumer spending, lower economic growth or recession, reduced demand for U.S. exports, disruptions to supply chains and decreased demand for other banking products and services), high unemployment and increasing insurance costs, as well as the financial stress to borrowers as a result of the foregoing, all of which could impact economic growth and could cause a reduction in financial transactions and business activities, including decreased deposits and reduced loan originations and our ability to manage liquidity in a rapidly changing and unpredictable market. Other factors that could cause actual results to differ materially from those indicated by forward-looking statements include, but are not limited to, the following:
•general (i) political conditions, including, without limitation, governmental action and uncertainty resulting from U.S. and global political trends and (ii) economic conditions, either globally, nationally, in the State of Texas, or in the specific markets in which we operate, including, without limitation, the deterioration of the commercial real estate, residential real estate, construction and development, energy, oil and gas, credit or liquidity markets, which could cause an adverse change in our net interest margin, or a decline in the value of our assets, which could result in realized losses, as well as the risks of an economic slowdown or recession and the effects of inflationary pressures, changes in interest rates, tariffs or trade wars (including reduced consumer spending, supply chain issues and adverse impacts to credit quality) and the related financial stress on borrowers and changes to customer behavior and credit risk as a result of the foregoing;
•changes in trade, monetary, and fiscal policies and laws, including actual changes in interest rates and the Fed Funds rate and changes in international trade policies, tariffs and treaties affecting imports and exports, and their related impacts on macroeconomic conditions, customer behavior, funding costs and loan and securities portfolios;
•inflation and fluctuations in interest rates that reduce our margins and yields, the fair value of financial instruments, the level of loan originations or prepayments on loans we have made and make, and the cost we pay to retain and attract deposits and secure other types of funding;
•current or future legislation, regulatory changes or changes in monetary or fiscal policy that adversely affect the businesses in which we or our customers or our borrowers are engaged, including the Federal Reserve's actions to manage interest rates, tariffs, trade policies, supply chain disruptions, immigration policies and/or disputes and other regulatory responses to economic conditions;
•the impact of interest rate fluctuations on our financial projections, models and guidance;
•legislative, tax and regulatory changes, including those that impact the money supply, trade, immigration and inflation;

•acts of terrorism, war or other conflicts, natural disasters, such as hurricanes, freezes, flooding and other man-made disasters, such as oil spills or power outages, health emergencies, epidemics or pandemics, climate change or other catastrophic events that may affect general economic conditions or cause other disruptions and/or increase costs, including, but not limited to, property and casualty and other insurance costs;
•potential impacts of the adverse developments in the banking industry highlighted by high-profile bank failures, including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto (including increases in the cost of our deposit insurance assessments);
•technological changes, including potential cyber-security incidents and other disruptions, developments in AI, or innovations to the financial services industry, including as a result of the increased telework environment;
•our ability to identify and address cyber-security risks such as data security breaches, malware, "denial of service" attacks, "hacking" and identity theft, which may be exacerbated by developments in generative AI and which could disrupt our business and result in the disclosure of and/or misuse or misappropriation of confidential or proprietary information, disruption or damage of our systems, increased costs, significant losses, or adverse effects to our reputation;
•changes in the interest rate yield curve such as flat, inverted or steep yield curves, or changes in the interest rate environment that impact net interest margins and may impact prepayments on our MBS portfolio;
•the risk that our enterprise risk management framework, compliance program or our corporate governance and supervisory oversight functions may not identify or address risks adequately, which may result in unexpected losses;
•the effect of compliance with legislation or regulatory changes;
•credit risks of borrowers, including any increase in those risks due to changing economic conditions, including inflation, interest rates, tariffs and immigration policies;
•increases in our nonperforming assets;
•risks related to environmental liability as a result of certain lending activity;

•execution of future acquisitions, reorganization or disposition transactions, including the risk that the anticipated benefits of such transactions are not realized;
•our ability to increase market share and control expenses;
•our ability to develop competitive new products and services in a timely manner and the acceptance of such products and services by our customers;
•the effect of changes in accounting policies and practices;
•adverse changes in the status or financial condition of the GSEs which impact the GSEs' guarantees or ability to pay or issue debt;

Critical Accounting Estimates
Our accounting and reporting estimates conform with U.S. GAAP and general practices within the financial services industry. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We consider accounting estimates that can (1) be replaced by other reasonable estimates and/or (2) changes to an estimate from period to period that have a material impact on the presentation of our financial condition, changes in financial condition or results of operations as well as (3) those estimates that require significant and complex assumptions about matters that are highly uncertain to be critical accounting estimates. We consider our critical accounting estimates to include allowance for credit losses on loans and off-balance-sheet credit exposure.
Critical accounting estimates include a high degree of uncertainty in the underlying assumptions. Management bases its estimates on historical experience, current information and other factors deemed relevant. The development, selection and disclosure of our critical accounting estimates are reviewed with the Audit Committee of the Company's Board of Directors. Actual results could differ from these estimates. For additional information regarding critical accounting policies, refer to "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Critical Accounting Estimates," "Part II - Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations - Allowance for Credit Losses - Loans and Allowance for Credit Losses - Off-Balance-Sheet Credit Exposures," "Note 1 - Summary of Significant Accounting and Reporting Policies," "Note 5 - Loans and Allowance for Loan Losses" and "Note 17 - Off-Balance-Sheet Arrangements, Commitments and Contingencies" in the 2025 Form 10-K. As of September 30, 2026, there have been no significant changes to our critical accounting estimates.

Non-GAAP Financial Measures
Certain non-GAAP measures are used by management to supplement the evaluation of our performance. These include the following fully taxable-equivalent measures: net interest income (FTE), net interest margin (FTE) and net interest spread (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.
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.
In the following table we present the reconciliation of net interest income to net interest income adjusted to a fully taxable-equivalent basis assuming a 21% marginal tax rate for interest earned on tax-exempt assets such as municipal loans and investment securities (dollars in thousands), along with the calculation of net interest margin (FTE) and net interest spread (FTE).

OVERVIEW
ECONOMIC CONDITIONS
Ongoing tariff negotiations and conflict in the Middle East have caused some uncertainty related to inflation levels, energy and gas prices, and their impact on interest rates and the overall economy, including the economy in the State of Texas. While it is too early to discern the likely outcome of these tariff negotiations and military conflicts, the current economic conditions and growth prospects for our markets continue to reflect a solid and overall positive outlook. Higher inflation levels, including higher energy and gas prices, and interest rate fluctuations could have a negative impact on both our consumer and commercial borrowers in the future. Overall, however, we believe that the Texas markets we serve remain healthy.
DEPOSITS
Our deposits were $6.01 billion at September 30, 2026, a decrease of $851.4 million, or 12.4%, from December 31, 2025. At September 30, 2026, we had 178,615 total deposit accounts with an average balance of $33,000. Our estimated uninsured deposits were 41.8% of total deposits as of September 30, 2026. When excluding affiliate deposits (Southside-owned deposits) and public fund deposits (all collateralized), our total estimated deposits without insurance or collateral was 26.8% of total deposits as of September 30, 2026.
Our noninterest bearing deposits represent approximately 23.3% of total deposits. During the three months ended September 30, 2026, our cost of interest bearing deposits decreased 37 basis points to 2.45% from 2.82% for the three months ended September 30, 2025. Our cost of total deposits for the third quarter of 2026 decreased 36 basis points to 1.89% from 2.25% for the three months ended September 30, 2025.
Our cost of interest bearing deposits decreased 30 basis points, from 2.83% for the nine months ended September 30, 2025 to 2.53% for the nine months ended September 30, 2026. Our cost of total deposits decreased 27 basis points, from 2.26% for the nine months ended September 30, 2025 to 1.99% for the nine months ended September 30, 2026.
CAPITAL RESOURCES AND LIQUIDITY
Our capital ratios and contingent liquidity sources remain solid. The table below shows our total lines of credit, borrowings, total amounts available for future liquidity, and swapped value as of September 30, 2026 (in thousands):

Operating Results
Net income was $28.0 million for the three months ended September 30, 2026, compared to $4.9 million for the same period in 2025, an increase of $23.1 million, or 469.4%. The increase in net income was largely driven by a $25.7 million increase in noninterest income and, to a lesser extent, a $4.6 million increase in net interest income and a $345,000 decrease in provision for credit losses, partially offset by a $6.1 million increase in income tax expense and a $1.5 million increase in noninterest expense. There were no sales of AFS securities during the three months ended September 30, 2026, compared to a net loss on sale of AFS securities, included in noninterest income, of $24.4 million for the same period in 2025. Earnings per diluted common share were $0.93 for the three months ended September 30, 2026, compared to $0.16 for the same period in 2025, an increase of $0.77, or 481.3%.
During the nine months ended September 30, 2026, our net income increased $29.8 million, or 61.9%, to $78.1 million from $48.2 million for the same period in 2025. The increase in net income was due to a $30.0 million increase in noninterest income and, to a lesser extent, $11.5 million increase in net interest income and a $232,000 decrease in provision for credit losses, partially offset by a $7.4 million increase in income tax expense and a $4.4 million increase in noninterest expense. There were no sales of AFS securities during the nine months ended September 30, 2026, compared to a net loss on sale of AFS securities, included in noninterest income, of $24.9 million for the same period in 2025. Earnings per diluted common share
Southside Bancshares, Inc. |46
increased $1.02, or 64.2%, to $2.61 for the nine months ended September 30, 2026, compared to $1.59 for the same period in 2025.
Financial Condition
Our total assets increased $350.5 million, or 4.1%, to $8.87 billion at September 30, 2026 from $8.51 billion at December 31, 2025. Our securities portfolio increased by $127.3 million, or 4.7%, to $2.83 billion at September 30, 2026, compared to $2.70 billion at December 31, 2025. The increase in the securities portfolio was due to an increase in MBS during the nine months ended September 30, 2026. Our FHLB stock increased $29.6 million, or 210.5%, to $43.7 million from $14.1 million at December 31, 2025, due to the increase in our FHLB borrowings during the nine months ended September 30, 2026.
Loans at September 30, 2026 were $4.96 billion, an increase of $140.7 million, or 2.9%, compared to $4.82 billion at December 31, 2025, due to increases of $65.3 million in commercial loans, $41.1 million in commercial owner-occupied loans, $23.1 million in commercial real estate loans, $21.0 million in municipal loans and $543,000 in 1-4 family residential loans. These increases were partially offset by decreases of $5.6 million in construction loans and $4.8 million in loans to individuals. Loans held for sale decreased $363,000, or 27.3%, to $969,000 at September 30, 2026 from $1.3 million at December 31, 2025.
Our nonperforming assets at September 30, 2026 decreased $22.4 million, or 58.6%, to $15.8 million and represented 0.18% of total assets, compared to $38.2 million, or 0.45% of total assets, at December 31, 2025, primarily due to a decrease of $27.5 million in restructured loans, partially offset by a $5.2 million increase in accruing loans past due more than 90 days. The decrease in restructured loans was due to the payoff of a $27.5 million restructured commercial real estate loan in the first quarter of 2026 that was originally restructured with an extension of maturity in the first quarter of 2025 to allow for an extended lease up period. There was one $5.2 million commercial real estate loan past due more than 90 days as of September 30, 2026 that subsequently paid off in full on October 1, 2026. Nonaccruing loans decreased $182,000, or 1.7%, to $10.3 million, and the ratio of nonaccruing loans to total loans was 0.21% and 0.22% for September 30, 2026 and December 31, 2025, respectively. There were no repossessed assets at September 30, 2026 or December 31, 2025. There was $331,000 of OREO at September 30, 2026 and $248,000 at December 31, 2025.
Our deposits decreased $851.4 million, or 12.4%, to $6.01 billion at September 30, 2026, from $6.87 billion at December 31, 2025, due to decreases in brokered deposits of $617.8 million, or 91.9%, and public fund deposits of $240.4 million, or 20.8%, partially offset by an increase in retail deposits of $6.8 million, or 0.1%. The marginal increase in retail deposits of $6.8 million consists of a $32.3 million increase in interest bearing deposits, partially offset by a $25.6 million decrease in noninterest bearing deposits.
Total FHLB borrowings increased $589.6 million, or 279.3%, to $800.8 million at September 30, 2026 from $211.1 million at December 31, 2025, due to a shift from brokered deposits into FHLB borrowings.
Other borrowings increased $685.9 million, or 328.7%, to $894.6 million at September 30, 2026, from $208.7 million at December 31, 2025, due to a $725.0 million increase in FRDW borrowings, partially offset by a $39.1 million decrease in repurchase agreements.
Our subordinated notes, net of unamortized debt issuance costs, decreased $92.0 million, or 38.4%, to $147.6 million at September 30, 2026 from $239.7 million at December 31, 2025, as a result of the full redemption of $100.0 million in aggregate principal amount of 3.875% fixed-to-floating rate subordinated notes during the first quarter of 2026. Refer to "Note 7 - Long-term Debt" in our consolidated financial statements included in this report for a detailed description of the terms of the redemption of the subordinated notes.
Our total shareholders' equity at September 30, 2026 decreased 0.6%, or $4.7 million, to $842.9 million, or 9.5% of total assets, compared to $847.6 million, or 10.0% of total assets, at December 31, 2025. The decrease in shareholders' equity was the result of other comprehensive loss of $54.2 million, cash dividends paid of $32.5 million and net issuance of common stock under employee stock plans of $407,000, partially offset by net income of $78.1 million, stock compensation expense of $3.6 million and common stock issued under our dividend reinvestment plan of $676,000.
Key financial indicators management follows include, but are not limited to, numerous interest rate sensitivity and interest rate risk indicators, credit risk, operations risk, liquidity risk, capital risk, regulatory risk, inflation risk, competition risk, yield curve risk, U.S. agency MBS prepayment risk and economic risk indicators.

Balance Sheet Strategy
Determining the appropriate size of the balance sheet is one of the critical decisions any bank makes. Our balance sheet is not merely the result of a series of micro-decisions, but rather the size is controlled based on the economics of assets compared to the economics of funding and funding sources. Changing interest rate environments and economic conditions require that we monitor the interest rate sensitivity of our assets, the funding driving our growth and closely align ALCO objectives accordingly.
We ended the third quarter of 2026 with approximately $12.9 million in available liquidity from the FRDW, in addition to the approximately $1.77 billion available from the credit line with FHLB due primarily to the blanket lien on our loan portfolio and to a lesser extent, securities available as collateral. At September 30, 2026, the estimated deposits, without insurance or collateral, to total deposits, excluding affiliate deposits (Southside-owned deposits) was 26.8%, or $1.61 billion.
From time to time, we may enter into certain interest rate swap contracts with third parties using specific variable rates, as well as short-term (generally three months or less) fixed rate borrowings designated as cash flow hedges under ASC Topic 815. At September 30, 2026, we had swap contracts covering $340 million in FRDW borrowings and $275 million in FHLB borrowings for a total of $615 million of cash flow hedges. We expect the cash flows from swap contracts to be highly effective in hedging the variability in future cash flows attributable to fluctuations in the underlying SOFR rate. At September 30, 2026, these contracts reflected a weighted average rate of 3.88% with a remaining average weighted maturity of 1.0 year. During the nine months ended September 30, 2026, $245 million cash flow hedge interest rate swap contracts matured. As of September 30, 2026, a pre-tax unrealized gain of $6.5 million was recognized in other comprehensive income, and there was no ineffective portion of these hedges. At December 31, 2025, the outstanding balance of cash flow hedges was $860 million. Refer to "Note 9 - Derivative Financial Instruments and Hedging Activities" in our consolidated financial statements included in this report for a detailed description of our hedging policy and methodology related to derivative instruments.
We continue to evaluate the lowest cost wholesale funding sources and will utilize either FHLB advances, FRDW borrowings, brokered deposits, or any combination of the three funding sources to minimize interest expense while also utilizing cash flow hedges to mitigate the impacts of interest rate movements. Wholesale funding and securities are utilized to enhance overall profitability, to determine the appropriate leverage of our capital and to determine acceptable levels of credit, interest rate and liquidity risk consistent with prudent capital management. Wholesale funds are invested primarily in U.S. agency MBS and long-term municipal securities and to a lesser extent, corporate securities. Although the securities often carry lower yields than loans, these securities generally (i) increase the overall quality of our assets due to either the implicit or explicit guarantees of the U.S. Government and the guarantees of the municipalities, (ii) are more liquid than individual loans and (iii) may be used to collateralize our borrowings or other obligations.
Risks associated with this asset structure include a potentially lower net interest rate spread and margin when compared to our peers, changes in the slope of the yield curve, increased interest rate risk, the length of interest rate cycles, changes in volatility or spreads associated with the MBS, municipal and corporate securities, the unpredictable nature of MBS prepayments and credit risks associated with the municipal and corporate securities. See "Part I - Item 1A. Risk Factors - Risks Related to Our Business" in the 2025 Form 10-K for a discussion of risks related to interest rates. An additional risk is significant increases in interest rates, especially long-term interest rates, which could adversely impact the fair value of the AFS securities portfolio and could also impact our equity capital. Due to the unpredictable nature of MBS prepayments, the length of interest rate cycles and the slope of the interest rate yield curve, net interest income could fluctuate more than simulated under the scenarios modeled by our ALCO and described under "Item 7A. Quantitative and Qualitative Disclosures about Market Risk" in this report.
Our securities portfolio increased $127.3 million, or 4.7%, from $2.70 billion at December 31, 2025 to $2.83 billion at September 30, 2026, with increases in U.S. Agency MBS, and to a lesser extent, corporate bonds, partially offset by a decrease in municipal securities. As a result, securities totaled 31.9% of total assets at September 30, 2026, compared to 31.8% at December 31, 2025. The increase in the U.S. Agency MBS was due to the purchase of $504.6 million of low premium and discounted MBS with coupons ranging from 4.50% to 6.00%. The increase in corporate bonds was due to the purchase of $25.5 million in 6.25% to 7.00% coupon corporate bonds. The net increase in the total securities portfolio was due to securities purchased during the nine months ended September 30, 2026, which more than offset maturities, principal payments and net amortization.
Cash and cash equivalents increased to 4.9% of total assets at September 30, 2026, compared to 4.6% at December 31, 2025.
Our FHLB borrowings increased $589.6 million, or 279.3%, to $800.8 million at September 30, 2026, from $211.1 million at December 31, 2025. As of September 30, 2026 and December 31, 2025, we had $835.0 million and $110.0 million, respectively, in borrowings from the FRDW.
As of September 30, 2026, our total wholesale funding as a percentage of deposits, not including brokered deposits, increased to 28.4% from 16.0% at December 31, 2025.

Our brokered deposits may consist of CDs and non-maturity deposits which may be raised quickly with terms tailored to our funding needs. We had $39.3 million brokered CDs at September 30, 2026, compared to $19.8 million at December 31, 2025. At September 30, 2026, our brokered CDs had a weighted average cost of 403 basis points and remaining maturities of less than three months. Our brokered non-maturity deposits decreased to $15.1 million at September 30, 2026, from $652.4 million at December 31, 2025, with a weighted average cost of 408 and 359 basis points, respectively. Our wholesale funding policy currently allows for maximum brokered deposits of the lesser of $1.05 billion, or 12% of total assets. Potential higher interest expense and lack of customer loyalty are risks associated with the use of brokered deposits.
At September 30, 2026, a portion of the securities portfolio was funded by non-maturity deposits, some of which are included in wholesale funding that accounts for approximately 58% of the funding source, of which approximately 36% is swapped at a fixed rate, providing protection from rising interest rates.
We have partial term fair value hedges for certain of our fixed rate callable AFS municipal securities and partial term fair value hedges of fixed rate AFS MBS using the portfolio layer method. The instruments are designated as fair value hedges as the changes in the fair value of the interest rate swap are expected to partially offset changes in the fair value of the hedged item attributable to changes in the SOFR swap rate, the designated benchmark interest rate. As of September 30, 2026, $24.1 million in hedging instruments were used to hedge municipal securities with a carrying amount of $18.6 million included in our AFS securities portfolio in our consolidated balance sheets, representing approximately 11.8% of the AFS municipal portfolio. As of September 30, 2026, $267.0 million in hedging instruments were used to hedge 88.4% of our AFS MBS portfolio with a carrying value of $1.26 billion. These derivative contracts involve the receipt of floating rate interest from a counterparty in exchange for us making fixed-rate payments over the life of the agreement, without the exchange of the underlying notional value.

Results of Operations
Our results of operations are dependent primarily on net interest income, which is the difference between the interest income earned on assets (loans and investments) and interest expense due on our funding sources (deposits and borrowings) during a particular period. Results of operations are also affected by our noninterest income, provision for credit losses, noninterest expenses and income tax expense. General economic and competitive conditions, particularly changes in interest rates, inflation, changes in interest rate yield curves, prepayment rates of MBS and loans, repricing of loan relationships, government policies and actions of regulatory authorities also significantly affect our results of operations. Future changes in applicable laws, regulations or government policies may also have a material impact on our results of operations. See "Part I - Item 1A. Risk Factors - Risks Related to Our Business" in the 2025 Form 10-K for further discussion of these risks.

Net Interest Income
Net interest income is one of the principal sources of a financial institution's earnings stream and represents the difference or spread between interest and fee income generated from interest earning assets and the interest expense paid on interest bearing liabilities. Fluctuations in interest rates or interest rate yield curves, as well as repricing characteristics and volume and changes in the mix of interest earning assets and interest bearing liabilities, materially impact net interest income. During the last four months of 2025, the Federal Reserve reduced the target federal funds rate by 75 basis points to 3.50% to 3.75%. During the third quarter of 2026, the Federal Reserve raised the target federal funds rate by 25 basis points to 3.75% to 4.00%.
Net interest income for the three months ended September 30, 2026 increased $4.6 million, or 8.2%, compared to the same period in 2025. The increase in net interest income was primarily due to an increase in average balance of our interest earning assets and a decrease in the average rate paid on our interest bearing liabilities, partially offset by an increase in the average balance of our interest bearing liabilities and a change in the mix of our interest earning assets. Total interest income increased $5.0 million, or 4.9%, to $106.9 million for the three months ended September 30, 2026, compared to $101.9 million during the same period in 2025. Total interest expense increased $396,000, or 0.9%, to $46.6 million for the three months ended September 30, 2026, compared to $46.2 million for the same period in 2025. Our net interest margin and our net interest margin (FTE), a non-GAAP measure, both increased to 2.92% and 3.02%, respectively, for the three months ended September 30, 2026, compared to 2.81% and 2.94%, respectively, for the same period in 2025. Our net interest spread and net interest spread (FTE), also a non-GAAP measure, was 2.26% and 2.36%, respectively, for the three months ended September 30, 2026, compared to 2.14% and 2.26%, respectively, for the same period in 2025. See "Non-GAAP Financial Measures" for more information and a reconciliation to GAAP.
Southside Bancshares, Inc. |50
Net interest income was $175.3 million for the nine months ended September 30, 2026, compared to $163.8 million for the same period in 2025, an increase of $11.5 million, or 7.0%. The increase in net interest income for the nine months ended September 30, 2026 was due to an increase in the average balance of our interest earning assets and a decrease in the average rate paid on our interest bearing liabilities, partially offset by an increase in the average balance of our interest bearing liabilities and a decrease in the yield on our interest earning assets. Total interest income increased $12.3 million, or 4.1%, to $313.0 million for the nine months ended September 30, 2026, compared to $300.7 million for the same period in 2025. Total interest expense increased $817,000, or 0.6%, to $137.7 million for the nine months ended September 30, 2026, compared to $136.9 million for the same period in 2025. Our net interest margin and net interest margin (FTE), a non-GAAP measure, increased to 2.88% and 2.97%, respectively, for the nine months ended September 30, 2026, compared to 2.79% and 2.92%, respectively, for the same period in 2025, and our net interest spread and net interest spread (FTE), also a non-GAAP measure, increased to 2.24% and 2.33%, respectively, compared to 2.12% and 2.24%, respectively, for the same period in 2025.

(1)Interest yields on loans and securities that are nontaxable for federal income tax purposes are presented on a fully taxable-equivalent basis. See "Non-GAAP Financial Measures" for more information and for a reconciliation to GAAP.
The increase in total interest income for the three months ended September 30, 2026, was attributable to a $349.4 million, or 4.4%, increase in the average balance of our interest earning assets when compared to the same period in 2025, partially offset by a change in the mix of our interest earning assets. The increase in total interest expense for the three months ended September 30, 2026, was primarily attributable to an increase in the average balance of our interest bearing liabilities of $269.6 million, or 4.4%, compared to the same period in 2025, partially offset by the decrease in the average rate paid on our interest bearing liabilities to 2.91% for the three months ended September 30, 2026, from 3.01% for the same period in 2025.

(1)Interest on loans includes net fees on loans that are not material in amount.
(2)For the purpose of calculating the average yield, the average balance of securities does not include unrealized gains and losses on AFS securities.
(3)Yield/rate includes the impact of applicable derivatives.
Note: As of September 30, 2026 and 2025, loans totaling $10.3 million and $8.0 million, respectively, were on nonaccrual status. Our policy is to reverse previously accrued but unpaid interest on nonaccrual loans; thereafter, interest income is recorded to the extent received, when appropriate.

(1)Interest yields on loans and securities that are nontaxable for federal income tax purposes are presented on a fully taxable-equivalent basis. See "Non-GAAP Financial Measures" for more information and for a reconciliation to GAAP.
The increase in total interest income was attributable to a $308.7 million, or 3.9%, increase in the average balance of our interest earning assets when compared to the same period in 2025, partially offset by the decrease in the average yield on earning assets to 5.23% for the nine months ended September 30, 2026, from 5.25% for the same period in 2025. The increase in total interest expense for the nine months ended September 30, 2026 was attributable to an increase in the average balance of our interest bearing liabilities of $263.6 million, or 4.3%, when compared to the same period in 2025, partially offset by a decrease in rate paid on interest bearing liabilities to 2.90% for the nine months ended September 30, 2026, from 3.01% for the same period in 2025.

The 214.5% increase in noninterest income for the three months ended September 30, 2026, when compared to the same period in 2025, was due to a decrease in net loss on sale of securities AFS and increases in trust fees, deposit services and brokerage services income. The 288.6% increase in noninterest income for the nine months ended September 30, 2026, when compared to the same period in 2025, was due to a decrease in net loss on sale of securities AFS and increases in trust fees, other noninterest income, deposit services income, BOLI and brokerage services income.
During the three and nine months ended September 30, 2025, we sold MBS and municipal securities that resulted in a net loss on sale of AFS securities of $24.4 million and $24.9 million, respectively.
Gain on sale of loans decreased for the three and nine months ended September 30, 2026, when compared to the same periods in 2025, due to a decrease in the volume of loans sold.
Trust fees increased for the three and nine months ended September 30, 2026, when compared to the same periods in 2025, due to an increase in assets under management, and to a lesser extent, fee repricing.
The increase in BOLI income for the nine months ended September 30, 2026, when compared to the same period in 2025, was due to death benefits of $590,000 realized in the first six months of 2026 for former covered officers, and to a lesser extent, the purchase of a new policy for $5.5 million late in the fourth quarter of 2025.
Brokerage services income increased for the three and nine months ended September 30, 2026, when compared to the same periods in 2025, due to an increase in assets under management.
Other noninterest income increased for the nine months ended September 30, 2026, when compared to the same period in 2025, primarily due to increases in mortgage servicing fee income, swap fee income, letter of credit fee and deluxe income, partially offset by a decrease in equity investment income.

The increase in noninterest expense for the three and nine months ended September 30, 2026, when compared to the same periods in 2025, was primarily due to increases in salaries and employee benefits expense and software and data processing expense. Additional increases for the nine months ended September 30, 2026 include the loss on redemption of subordinated notes and advertising, travel and entertainment, partially offset by a decrease in other noninterest expense.
Salaries and employee benefits expense increased during the three months ended September 30, 2026, compared to the same period in 2025, due to increases in direct salary expense and retirement expense, partially offset by a decrease in health insurance expense. Salaries and employee benefits expense increased during the nine months ended September 30, 2026, compared to the same period in 2025, due to increases in direct salary expense, retirement expense and health insurance expense.
For the three and nine months ended September 30, 2026, direct salary expense increased $928,000, or 4.8%, and $3.0 million, or 5.2%, respectively, when compared to the same periods in 2025, primarily due to normal salary increases effective in the first quarter of 2026 and an increase in stock compensation expense.
Retirement expense, included in salaries and employee benefits, increased $26,000, or 2.8%, and $487,000, or 18.3%, for the three and nine months ended September 30, 2026, respectively, when compared to the same periods in 2025. The increase during the nine months ended September 30, 2026, was primarily due to an increase in our split dollar expense related to the execution of a new split dollar agreement with an executive officer.
Southside Bancshares, Inc. |57
Health and life insurance expense, included in salaries and employee benefits, decreased $15,000, or 0.6%, for the three months ended September 30, 2026, compared to the same period in 2025, and increased $84,000, or 1.3%, for the nine months ended September 30, 2026, when compared to the same period in 2025, primarily due to premiums for a new short-term disability policy. We have a self-insured health plan which is supplemented with a stop loss policy.
Advertising, travel and entertainment expense increased for the three months ended September 30, 2026, when compared to the same period in 2025, due to increases in media advertising, sponsorships and travel related expenses. The increase in advertising, travel and entertainment expense for the nine months ended September 30, 2026, when compared to the same period in 2025, was due to an increase in media advertising, sponsorships and meals and entertainment expense.
ATM expense decreased for the three and nine months ended September 30, 2026, when compared to the same periods in 2025. The decrease for the three months ended September 30, 2026 was primarily due to decreases in ATM maintenance and armored car expense while the decrease for the nine months ended September 30, 2026 was due to decreases in armored car expense, and to a lesser extent, ATM repairs, system maintenance and branding fees.
Software and data processing expense increased for the three and nine months ended September 30, 2026, when compared to the same periods in 2025, primarily resulting from an increase in data processing expense due to the transition from in-house core processing to an outsourced solution.
Communications expense decreased for the nine months ended September 30, 2026, when compared to the same period in 2025, resulting from improved network management efficiency.
Amortization of intangibles decreased for the three and nine months ended September 30, 2026, when compared to the same periods in 2025, due primarily to a decrease in core deposit intangible amortization which is recognized on an accelerated method resulting in a decline in expense over the amortization period.
Loss on redemption of subordinated notes consisted of the remaining unamortized discount of $601,000 and debt issuance costs of $190,000 associated with the notes at the time of redemption on February 15, 2026.
Income Taxes
Pre-tax income for the three and nine months ended September 30, 2026 was $34.3 million and $95.1 million, respectively, an increase of 571.5% and 64.4%, compared to $5.1 million and $57.9 million for the three and nine months ended September 30, 2025, respectively. We recorded income tax expense of $6.3 million and $17.1 million for the three and nine months ended September 30, 2026, respectively, compared to income tax expense of $189,000 and $9.6 million for the same periods in 2025. The ETR as a percentage of pre-tax income was 18.3% and 17.9% for the three and nine months ended September 30, 2026, respectively, compared to an ETR as a percentage of pre-tax income of 3.7% and 16.6% the three and nine months ended September 30, 2025, respectively. The increase in the ETR for the three and nine months ended September 30, 2026 was 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 net tax-exempt income as a percentage of pre-tax income.
The ETR differs from the statutory rate of 21% primarily due to the effect of tax-exempt income from municipal loans and securities, BOLI and state income tax. The net deferred tax asset totaled $42.0 million at September 30, 2026, compared to $27.1 million at December 31, 2025. The increase in the net deferred tax asset is primarily the result of an increase in the unrealized loss in the AFS securities portfolio.
See "Note 11 - Income Taxes" to our consolidated financial statements included in this report. No valuation allowance was recorded at September 30, 2026 or December 31, 2025, as management believes it is more likely than not that all of the deferred tax asset items will be realized in future years.

Composition of Loans
One of our main objectives is to seek attractive lending opportunities in Texas, primarily in the market areas in which we operate. Refer to "Part I - Item 1. Business - Market Area" in the 2025 Form 10-K for a discussion of our primary market area and the geographic concentration of our loan portfolio as of December 31, 2025. There were no substantial changes in these concentrations during the nine months ended September 30, 2026. The majority of our loan originations are made to borrowers who live in and/or conduct business in the market areas of Texas in which we operate or adjoin, with the exception of municipal loans, which are made primarily throughout the state of Texas. Municipal loans are made to municipalities, counties, school districts and colleges.

Our total loan portfolio increased $140.7 million, or 2.9%, compared to December 31, 2025, and increased $193.4 million, or 4.1%, compared to September 30, 2025. From December 31, 2025, increases occurred in all categories except construction and loans to individuals. From September 30, 2025, increases occurred in all categories except loans to individuals and 1-4 family residential.
At September 30, 2026, our real estate loans represented 81.6% of our loan portfolio and were comprised of commercial real estate loans of 59.8%, 1-4 family residential loans of 17.9%, construction loans of 13.4% and commercial owner-occupied of 8.9%. Commercial real estate loans and commercial owner-occupied primarily include loans collateralized by retail, commercial office buildings, multi-family residential buildings, medical facilities and offices, senior living, assisted living and skilled nursing facilities, warehouse facilities, hotels and churches. Our 1-4 family residential loans consist primarily of loans secured by first mortgages on owner occupied 1-4 family residences. Our construction loans are collateralized by property located primarily in or near the market areas we serve.
Nonperforming Assets
Nonperforming assets consist of delinquent loans 90 days or more past due, nonaccrual loans, OREO, repossessed assets and restructured loans. Nonaccrual loans are loans 90 days or more delinquent and collection in full of both the principal and interest is not expected. Additionally, some loans that are not delinquent or that are delinquent less than 90 days may be placed on nonaccrual status if it is probable that we will not receive contractual principal and interest payments in accordance with the terms of the respective loan agreements. When a loan is categorized as nonaccrual, the accrual of interest is discontinued and any accrued balance is reversed for financial statement purposes. OREO represents real estate taken in full or partial satisfaction of debts previously contracted. The dollar amount of OREO is based on a current evaluation of the OREO at the time it is recorded on our books, net of estimated selling costs. Updated valuations are obtained as needed and any additional impairments are recognized. Restructured loans represent loans that have been modified due to the borrower experiencing financial difficulty by providing interest rate reductions or below market interest rates, restructuring amortization schedules and other actions intended to minimize potential losses. Categorization of a loan as nonperforming is not in itself a reliable indicator of potential loan loss. Other factors, such as the value of collateral securing the loan and the financial condition of the borrower, are considered in judgments as to potential loan loss.

Nonperforming assets hinder our ability to earn interest income. Decreases in earnings can result from both the loss of interest income and the costs associated with maintaining the OREO, for taxes, insurance and other operating expenses. We actively market all OREO properties and do not hold them for investment purposes.
Allowance for Credit Losses - Loans
In accordance with ASC 326, the allowance for credit losses on loans is estimated and recognized upon origination of the loan based on expected credit losses. The CECL model uses historical experience and current conditions for homogeneous pools of loans, and reasonable and supportable forecasts about future events. The impact of varying economic conditions and portfolio stress factors are a component of the credit loss models applied to each portfolio. Reserve factors are specific to the loan segments that share similar risk characteristics based on the probability of default assumptions and loss given default assumptions, over the contractual term. The forecasted periods gradually mean-revert the economic inputs to their long-run historical trends. Management evaluates the economic data points used in the Moody's forecasting scenarios on a quarterly basis to determine the most appropriate impact to the various portfolio characteristics based on management's view and applies weighting to various forecasting scenarios as deemed appropriate based on known and expected economic activities. Management also considers and may apply relevant qualitative factors, not previously considered, to determine the appropriate allowance level. The use of the CECL model includes significant judgment by management and may differ from those of our peers due to different historical loss patterns, economic forecasts, and the length of time of the reasonable and supportable forecast period and reversion period.
We utilize Moody's Analytics economic forecast scenarios and assign probability weighting to those scenarios which best reflect management's views on the economic forecast. The probability weighting and scenarios utilized for the estimate of the allowance were generally reflective of the economic forecast in our CECL model as of September 30, 2026.
When determining the appropriate allowance for credit losses on our loan portfolio, our commercial construction, commercial owner-occupied and commercial real estate loans, commercial loans and municipal loans utilize the probability of default/loss given default discounted cash flow approach. Reserves on these loans are based upon risk factors including the loan type and
Southside Bancshares, Inc. |60
structure, collateral type, leverage ratio, refinancing risk and origination quality, among others. Our consumer construction real estate loans, 1-4 family residential loans and our loans to individuals use a loss rate based upon risk factors including loan types, origination year and credit scores.
Loans evaluated collectively in a pool are monitored to ensure they continue to exhibit similar risk characteristics with other loans in the pool. If a loan does not share similar risk characteristics with other loans, expected credit losses for that loan are evaluated individually.
As of September 30, 2026, our review of the loan portfolio indicated that an allowance for loan losses of $46.9 million was appropriate to cover expected losses in the portfolio. Changes in economic and other conditions, including the application of the CECL model, may require future adjustments to the allowance for loan losses.
During the nine months ended September 30, 2026, the allowance for loan losses increased $1.8 million, or 3.9%, to $46.9 million, or 0.94% of total loans, when compared to $45.1 million, or 0.94% of total loans, at December 31, 2025.
For the three and nine months ended September 30, 2026, loan charge-offs were $727,000 and $2.3 million, respectively, and recoveries were $1.0 million and $2.1 million, respectively. For the three and nine months ended September 30, 2025, loan charge-offs were $1.3 million and $3.1 million, respectively, and recoveries were $491,000 and $1.1 million, respectively. For the three and nine months ended September 30, 2026, we recorded a provision for credit losses for loans of $946,000 and $1.9 million, respectively. For the three and nine months ended September 30, 2025, we recorded a provision for credit losses for loans of $1.7 million and $2.4 million, respectively.

Our off-balance-sheet credit exposures include contractual commitments to extend credit and standby letters of credit. For these credit exposures we evaluate the expected credit losses using usage given defaults and credit conversion factors depending on the type of commitment and based upon historical usage rates. These assumptions are reevaluated on an annual basis and adjusted if necessary. For additional information regarding our methodology used to estimate the allowance for credit losses on off-balance-sheet credit exposures, see "Note 12 - Off-Balance-Sheet Arrangements, Commitments and Contingencies" to our consolidated financial statements included in this report.

Capital Resources and Liquidity
Our total shareholders' equity at September 30, 2026 decreased 0.6%, or $4.7 million, to $842.9 million, or 9.5% of total assets, compared to $847.6 million, or 10.0% of total assets, at December 31, 2025. The decrease in shareholders' equity was the result of other comprehensive loss of $54.2 million, cash dividends paid of $32.5 million and net issuance of common stock under employee stock plans of $407,000, partially offset by net income of $78.1 million, stock compensation expense of $3.6 million and common stock issued under our dividend reinvestment plan of $676,000.
The Company's Common Equity Tier 1 capital includes common stock and related paid-in capital, net of treasury stock, and retained earnings. The Bank's Common Equity Tier 1 capital includes common stock and related paid-in capital and retained earnings. In connection with the adoption of the Basel III Capital Rules, we elected to opt-out of the requirement to include accumulated other comprehensive income in Common Equity Tier 1. Common Equity Tier 1 for both the Company and the Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities.
Tier 1 capital includes Common Equity Tier 1 capital and additional Tier 1 capital. For the Company, additional Tier 1 capital at September 30, 2026 included $58.5 million of trust preferred securities. For bank holding companies that had assets of less than $15 billion as of December 31, 2009, trust preferred securities issued prior to May 19, 2010 can be treated as Tier 1 capital to the extent that they do not exceed 25% of Tier 1 capital after the application of capital deductions and adjustments. The Bank did not have any additional Tier 1 capital beyond Common Equity Tier 1 at September 30, 2026.
Total capital includes Tier 1 capital and Tier 2 capital. Tier 2 capital for both the Company and the Bank includes a permissible portion of the allowance for credit losses on loans, off-balance sheet exposures and HTM securities. Tier 2 capital for the Company also includes $147.6 million of qualified subordinated debt as of September 30, 2026. The permissible portion of qualified subordinated notes decreases 20% per year during the final five years of the term of the notes.
Management believes that, as of September 30, 2026, we met all capital adequacy requirements to which we were subject. It is management's intention to maintain our capital at a level acceptable to all regulatory authorities and future dividend payments will be determined accordingly. Regulatory authorities require that any dividend payments made by either the Company or the Bank not exceed earnings for that year. Accordingly, shareholders should not anticipate a continuation of the cash dividend payments simply because of the existence of a dividend reinvestment program. The payment of dividends will depend upon future earnings, our financial condition and other related factors, including the discretion of the Board.

Management of Liquidity
Liquidity management involves our ability to convert assets to cash with minimum risk of loss while enabling us to meet our current and future obligations to our customers at any time. This means addressing: (1) the immediate cash withdrawal requirements of depositors and other fund providers; (2) the funding requirements of lines and letters of credit; and (3) the short-term credit needs of customers. Liquidity is provided by cash, interest earning deposits and short-term investments that can be readily liquidated with a minimum risk of loss. At September 30, 2026, these investments were 6.8% of total assets, as compared with 8.1% and 8.8% for December 31, 2025 and September 30, 2025, respectively. The decrease to 6.8% at September 30, 2026 as compared to December 31, 2025, is largely driven by an increase in total assets and a decrease in the short-term investment portfolio and cash and due from banks. The decrease to 6.8% at September 30, 2026 as compared to September 30, 2025, is largely driven by an increase in total assets and a decrease in the short-term investment portfolio, interest earning deposits and cash and due from banks. Liquidity is further provided through the matching, by time period, of rate sensitive interest earning assets with rate sensitive interest bearing liabilities. The Bank has three unsecured lines of credit for the purchase of overnight federal funds at prevailing rates with Frost Bank, Amegy Bank and TIB - The Independent Bankers Bank for $40.0 million, $25.0 million and $15.0 million, respectively. There were no federal funds purchased at September 30, 2026 or December 31, 2025. To provide more liquidity in response to economic conditions in recent years, the Federal Reserve has encouraged broader use of the discount window. At September 30, 2026, the amount of additional funding the Bank could obtain from the FRDW, collateralized by securities, was approximately $12.9 million. At September 30, 2026 and December 31, 2025, we had $835.0 million and $110.0 million, respectively, in borrowings from the FRDW. At September 30, 2026, the amount of additional funding Southside Bank could obtain from FHLB, collateralized by FHLB stock, nonspecified loans and/or securities, was approximately $1.77 billion, net of FHLB stock purchases required. The Bank has a $5.0 million line of credit with Frost Bank to be used to issue letters of credit, and at September 30, 2026, the line had one outstanding letter of credit for $155,000. The Bank currently has four outstanding letters of credit from FHLB held as collateral for loans totaling $19.3 million.
Interest rate sensitivity management seeks to avoid fluctuating net interest margins and to enhance consistent growth of net interest income through periods of changing interest rates. The ALCO closely monitors various liquidity ratios and interest rate spreads and margins. The ALCO utilizes a simulation model to perform interest rate simulation tests that apply various interest rate scenarios including immediate shocks and MVPE to assist in determining our overall interest rate risk and the adequacy of our liquidity position. In addition, the ALCO utilizes this simulation model to determine the impact on net interest income of various interest rate scenarios. By utilizing this methodology, we can determine potential changes to make to the asset and liability mix to minimize the change in net interest income under these various interest rate scenarios.
Management continually evaluates our liquidity position and currently believes the Company has adequate funding to meet our financial needs.
