The following discussion should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021, and the Selected Financial Data and Consolidated Financial Statements included elsewhere herein. Special Cautionary Notice Regarding Forward Looking Information Certain matters discussed in this report, excluding historical information, include forward-looking statements, within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and are subject to the safe harbor created by these sections. Although we believe such forward-looking statements are based on reasonable assumptions, no assurance can be given that every objective will be reached. The words “estimate,” “expect,” “intend,” “believe” and “project,” as well as other words or expressions of a similar meaning, are intended to identify forward-looking statements. Readers are cautioned not to place undue reliance on forward-looking statements, which speak only as of the date of this report. Such statements are based on current expectations, are inherently uncertain, are subject to risks and should be viewed with caution. Actual results and experience may differ materially from the forward-looking statements as a result of many factors. Risk factors that could cause actual results to differ materially from any results that we project, forecast, estimate or budget in forward-looking statements include, among others, the following possibilities: • Local, regional, national and international economic business conditions and the impact they may have on us, our customers, and such customers’ ability to transact profitable business with us, including the ability of our borrowers to repay their loans according to their terms or a change in the value of the related collateral. • Volatility and disruption in national and international financial markets. • Government intervention in the U.S. financial system. • The unavailability of funding from the FHLB, the Fed or other sources in the future could adversely impact our growth strategy, prospects and performance. • Changes in consumer spending, borrowing and saving habits. • Changes in interest rates and market prices, including, changes in federal regulations on the payment of interest on demand deposits. • Changes in the capital markets we utilize, including changes in the interest rate environment that may reduce margins. • Changes in state and/or federal laws and regulations, including, the impact of the Consumer Financial Protection Bureau (“CFPB”) as a regulator of financial institutions, changes in the accounting, tax and regulatory treatment of trust preferred securities, as well as changes in banking, tax, securities, insurance, employment, environmental and immigration laws and regulations and the risk of litigation that may follow. • Changes in U.S.—Mexico trade, including, reductions in border crossings and commerce, integration and implementation of the United States-Mexico-Canada Agreement and the possible imposition of tariffs on imported goods. • The reduction of deposits from nonresident alien individuals due to the IRS rules requiring U.S. financial institutions to report deposit interest payments made to such individuals. • The loss of senior management or operating personnel. • The timing, impact and other uncertainties of the potential future acquisitions, as well as our ability to maintain our current branch network and enter new markets to capitalize on growth opportunities. • Changes in estimates of future reserve requirements based upon periodic review thereof under relevant regulatory and accounting requirements. 2 • Additions to our allowance for credit loss as a result of changes in local, national or international conditions which adversely affect our customers. • Greater than expected costs or difficulties related to the development and integration of new products and • lines of business. Increased labor costs and effects related to health care reform and other laws, regulations and legal developments impacting labor costs. Impairment of carrying value of goodwill could negatively impact our earnings and capital. • • Changes in the soundness of other financial institutions with which we interact. • Political instability in the United States or Mexico. • Technological changes or system failures or breaches of our network security, as well as other cyber security risks, could subject us to increased operating costs, litigation and other liabilities. • Acts of war or terrorism. • Natural disasters. • Reduced earnings resulting from the write down of the carrying value of securities held in our securities available-for-sale portfolios. • The effect of changes in accounting policies and practices by the Public Company Accounting Oversight Board, the Financial Accounting Standards Board and other accounting standards setters. • The costs and effects of regulatory developments or regulatory or other governmental inquiries and the results of regulatory examinations or reviews and obtaining regulatory approvals. • The effect of final rules amending Regulation E that prohibit financial institutions from charging consumer fees for paying overdrafts on ATM and one-time debit card transactions, as well as the effect of any other regulatory or legal developments that limit overdraft services. • The reduction of income and possible increase in required capital levels related to the adoption of legislation, including and the implementing rules and regulations, including those that establish debit card interchange fee standards and prohibit network exclusivity arrangements and routing restrictions. • The increase in required capital levels related to the implementation of capital and liquidity rules of the federal banking agencies that address or are impacted by the Basel III capital and liquidity standards. • The enhanced due diligence burden imposed on banks related to the banks’ inability to rely on credit ratings under Dodd-Frank. • Our failure or circumvention of our internal controls and risk management, policies and procedures. • Potential direct and indirect impacts, risks, and uncertainties associated with the novel Coronavirus Disease 2019 (“COVID-19”) or similar global pandemics. Forward-looking statements speak only as of the date on which such statements are made. It is not possible to foresee or identify all such factors. We make no commitment to update any forward-looking statement, or to disclose any facts, events or circumstances after the date hereof that may affect the accuracy of any forward-looking statement, unless required by law. Overview We are headquartered in Laredo, Texas, with 170 facilities and 263 ATMs, providing banking services for commercial, consumer and international customers of north, south, central and southeast Texas and the State of Oklahoma. We are one of the largest independent commercial bank holding companies headquartered in Texas. We, through our Subsidiary Banks, are in the business of gathering funds from various sources and investing those funds in order to earn a return. We, either directly or through a Subsidiary Bank, own one insurance agency, a liquidating subsidiary, a fifty percent interest in an investment banking unit that owns a broker/dealer, a controlling interest in four merchant banking entities, and a majority ownership in a real-estate development partnership. Our primary earnings come from the spread between the interest earned on interest-bearing assets and the interest paid on interest-bearing liabilities. In addition, we generate 3 income from fees on products offered to commercial, consumer and international customers. The sales team of each of our Subsidiary Banks aims to match the right mix of products and services to each customer to best serve the customer’s needs. That process entails spending time with customers to assess those needs and servicing the sales arising from those discussions on a long-term basis. Our Subsidiary Banks have various compensation plans, including incentive-based compensation, for fairly compensating employees. Our Subsidiary Banks also have a robust process in place to review sales that support the incentive-based compensation plan to monitor the quality of the sales and identify any significant irregularities, a process that has been in place for many years. One of our primary goals is to grow net interest income and non-interest income while adequately managing credit risk, interest rate risk and expenses. Effective management of capital is one of our critical objectives. A key measure of the performance of a banking institution is the return on average common equity (“ROE”). Our ROE for the year ended December 31, 2021 was 11.28% as compared to 7.86% for the year ended December 31, 2020. We are very active in facilitating trade along the United States border with Mexico. We do a large amount of business with customers domiciled in Mexico and deposits from persons and entities domiciled in Mexico comprise a large and stable portion of the deposit base of our Subsidiary Banks. We also serve the growing Hispanic population through our facilities located throughout north, south, central and southeast Texas and the State of Oklahoma. Expense control is an essential element of our long-term profitability. It has been a constant focus of ours for many years and is especially critical during periods of economic uncertainty. At the onset of the COVID-19 pandemic, management, though a variety of tools, immediately took action and introduced cost-savings measures across our Company, recognizing that the COVID-19 pandemic and the impact it had on market interest rates and other business activities potentially could have severely impacted our business. As a result, we have achieved a decrease of approximately 15% or $46.5 million, before tax, in non-interest expense over the two-year period ended December 31, 2021, primarily driven by decreases in our employee compensation and benefit plan expenses, professional fees and other general operating expenses with the ultimate goal of ensuring that we align our workforce and operating expenses with our revenue streams. In March 2020, the World Health Organization recognized the outbreak of COVID-19 as a pandemic. The spread of COVID-19 and resulting global health crisis has created extreme negative consequences and disruption in global financial markets and curtailed activity in the governmental, commercial and consumer sectors in 2020 and 2021. Government responses at all levels have included ordering non-essential businesses be closed, mandating that individuals not working in essential businesses restrict their movement, observe social distancing and shelter in place. Although some of the governmental mandates have been lifted with the development of several vaccines for COVID-19, the long-term consequences of those actions, and the responses by individuals and businesses affected, remain to be seen. The rapid decreases in consumer and commercial activity, rapid increases in unemployment, disruption in global supply chains, market downturns and volatility, drastic changes in consumer behavior, new legislation in response to the emergency and decreases in interest rates seen throughout 2020 continued to impact 2021. We have continued to work with our customers to assist them through these difficult times and we are continuing to capitalize on our strong capital position and strong liquidity to ensure that we are correctly positioned and have the financial strength to navigate the crisis to protect our Company, our employees, our customers and our shareholders. In order to protect the health of our employees and customers, while still filling the needs in the communities we serve as an essential business, we have taken steps to ensure proper safety protocols are in place, including enforcing local ordinances, discontinuing significant travel, ensuring social distancing, increasing disinfecting of our facilities, establishing a human resources hotline to address employee concerns and establishing a task force to ensure we are making good decisions. For our customers, we are also working with them on a case-by-case basis on temporary deferrals of interest and/or principal payments on loans and responding to other individual needs of those customers that continue to experience financial distress. On March 27, 2020, the Coronavirus Aid, Relief and Economic Security (“CARES”) Act was signed into law. It contains substantial tax and spending provisions intended to address the impact of the COVID-19 pandemic. The CARES Act includes the Paycheck Protection Program (“PPP”), originally a nearly $350 billion program designed to aid small businesses through federally guaranteed loans distributed through banks. These loans were originally intended to support eight weeks of payroll and certain other costs to help those businesses remain viable and allow their employees to pay 4 their bills. Subsequently, on April 24, 2020, the Paycheck Protection Program and Health Care Enhancement Act (“CARES Part II”) was signed into law. CARES Part II provided an additional funding of $320 billion for the PPP program. Then, on June 5, 2020, the Paycheck Protection Program Flexibility Act (“PPPFA”) was signed into law. The PPPFA, among other things, extended the period of time that businesses could spend PPP loan proceeds on payroll and other eligible costs from eight weeks to the earlier of 24 weeks or December 31, 2020. On December 27, 2020, the Economic Aid to Hard-Hit Small Businesses, Nonprofits and Venues Act (the “Economic Aid Act”) was enacted, which among other things, reauthorized lending under the PPP to first-time borrowers and for second draws by certain borrowers who have previously received PPP loans. The Economic Aid Act made available an additional $147 billion for PPP loans requested by March 31, 2021. We have been active participants in helping our customers obtain PPP loans under all the PPP programs, and as of February 18, 2022, have approximately 968 loans with an approximate value of $71,149,000 outstanding. Future economic conditions remain uncertain and the impact of those conditions on our business also remains uncertain. Our business depends on the willingness and ability of our customers to conduct banking and other financial transactions. Our revenue streams including service charges on deposits and banking and non-banking service charges and fees (ATM and interchange income) have been impacted and may continue to be impacted in the future if economic conditions do not improve. Expense control has been a long-time focus and essential element to our long-term profitability. We have kept that focus in mind as we continue to look at operations and create efficiencies and institute cost-control protocols at all levels. We will continue to monitor our efficiency ratio, a measure of non-interest expense to net interest income plus non-interest income and our overhead burden ratio, a ratio of our operating expenses against total assets, closely. We use these measures in determining if we are accomplishing our long-term goals of controlling our costs in order to provide superior returns to our shareholders.

Net income for 2021 was positively impacted by the sale of an equity interest in a merchant banking investment held by one of our non-bank subsidiaries totaling $42.8 million, net of tax, in the second quarter of 2021. Net income for 2021 was positively impacted by a decrease in the provision for credit losses compared to the same period of 2020. We adopted the provisions of Accounting Standards Update No. 2016-13, “Financial Instruments – Credit Losses: (“ASU 2016-13”) on January 1, 2020, resulting in a transition from the long-standing incurred loss model to an expected credit loss model, which recognizes credit losses over the life of a financial asset. Expected credit losses capture historical information, current conditions, and reasonable and supportable forecasts of future conditions. The impact of the adoption resulted in a one-time charge to capital of $8.3 million, net of tax. The credit loss expense charged to operations increased throughout 2020 as a result of increases in the allowance for credit losses (“ACL”) due to deteriorating economic conditions as a result of COVID-19 and the impact of those conditions on certain segments of our loan portfolio. Economic conditions during 2021 stabilized or improved in certain segments. The pool specific qualitative loss factors management deemed appropriate for the ACL calculation at December 31, 2020 remained constant in the December 31, 2021 ACL calculation, which positively impacted the calculation and resulted in a decrease of $29.6 million, net of tax, in the credit loss expense charged to operations for the year ended December 31, 2021 compared to the same period of 2020. Net Interest Income Net interest income is the spread between income on interest-earning assets, such as loans and securities, and the interest expense on liabilities used to fund those assets, such as deposits, repurchase agreements and funds borrowed. Net interest income is our largest source of revenue. Net interest income is affected by both changes in the level of interest 6 rates and changes in the amount and composition of interest-earning assets and interest-bearing liabilities. Tax-exempt yields have not been adjusted to a tax-equivalent basis.

The yield on average interest-earning assets decreased 21% from 3.72% in 2020 to 2.94% in 2021, and the rates paid on average interest-bearing liabilities decreased 39.0% from 0.59% in 2020 to 0.36% in 2021. The yield on average interest-earning assets decreased 22.0% from 4.77% in 2019 to 3.72% in 2020, and the rates paid on average interest-bearing liabilities decreased 36.6% from .93% in 2019 to .59% in 2020. The majority of our taxable investment securities are invested in mortgage backed securities and, during rapid increases or reduction in interest rates, the yield on these securities do not re-price as quickly as the loans. 7 The following table analyzes the changes in net interest income during 2021, 2020 and 2019 and the relative effect of changes in interest rates and volumes for each major classification of interest-earning assets and interest-bearing liabilities.

As part of our strategy to manage interest rate risk, we strive to manage both assets and liabilities so that interest sensitivities match. One method of calculating interest rate sensitivity is through gap analysis. A gap is the difference between the amount of interest rate sensitive assets and interest rate sensitive liabilities that re-price or mature in a given time period. Positive gaps occur when interest rate sensitive assets exceed interest rate sensitive liabilities, and negative gaps occur when interest rate sensitive liabilities exceed interest rate sensitive assets. A positive gap position in a period of rising interest rates should have a positive effect on net interest income as assets will re-price faster than liabilities. Conversely, net interest income should contract somewhat in a period of falling interest rates. Our management can quickly change our interest rate position at any given point in time as market conditions dictate. Additionally, interest rate changes do not affect all categories of assets and liabilities equally or at the same time. Analytical techniques we employ to supplement gap analysis include simulation analysis to quantify interest rate risk exposure. The gap analysis prepared by management is reviewed by our Investment Committee at least twice a year. The Investment Committee is comprised of certain members of the board of directors and senior managers of the various Subsidiary Banks. Management currently believes that we are properly positioned for interest rate changes; however, if management determines at any time that we are not properly positioned, we will strive to adjust the interest rate sensitive assets and liabilities in order to manage the effect of interest rate changes. We have established guidelines for acceptable volatility of projected net interest income on the income simulation analysis and the guidelines are reviewed at least annually. As of December 31, 2021, in rising rate scenarios of +100, +200, +300 and +400 basis points, the guidelines established by management require that the net interest income not vary 8 by more than minus 15%, 15%, 15%, and 20%, respectively, for the first 12-month period projected. Given the current low interest rate environment, no downward rate shifts were modeled in our income simulations. At December 31, 2021, the income simulations show that a rate shift of +100, +200, +300 and +400 basis points in interest rates up will vary projected net interest income for the coming 12-month period by +15.6%, +30.47%, +45.95%, and +61.42%, respectively. The basis point shift in interest rates is a hypothetical rate scenario used to calibrate risk and does not necessarily represent management’s current view of future market developments. We believe that we are properly positioned for a potential interest rate increase or decrease. Allowance for Credit Losses The ACL increased 1.2% to $110,374,000 at December 31, 2021 from $109,059,000 at December 31, 2020. The provision for credit losses charged to expense decreased $37,424,000 to $7,955,000 for the year ended December 31, 2021 from $45,379,000 for the same period in 2020. We adopted the provisions of ASU 2016-13 on January 1, 2020, resulting in a transition from the long-standing incurred loss model to an expected credit loss model, which recognizes credit losses over the life of a financial asset. The change in methodology combined with deteriorating economic conditions occurring in 2020 as a result of COVID-19 and the impact of those conditions on certain segments of our calculation, resulted in an increase in credit loss expense in 2020. 9 The following table summarizes loan balances at the end of each year and average loans outstanding during the year and the following ratios: nonaccrual loans to total loans, nonaccrual loans to the ACL, charge-offs to average loans, by loan type, and total charge-off to average total loans.: 2021 2020 2019 Allowance for credit losses to total loans outstanding . . . . . . . . . . . . .

The ACL’s are established through charges to operations in the form of provisions for credit losses. The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial and agricultural or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure beyond any collateral coverage is apparent, (ii) when no further collection of the portion of the loan so exposed is anticipated based on actual results, (iii) when the credit enhancements, if any, are not adequate, and (iv) when the borrower’s financial condition would so indicate. Generally, unsecured consumer loans are charged-off when 90 days past due. The ACL is a reserve established through a provision for credit losses charged to expense, which represents management’s best estimate of credit losses within the existing portfolio of loans based on our internal ACL calculation. While our management considers that it is generally able to identify borrowers with financial problems reasonably early and to monitor credit extended to such borrowers carefully, there is no precise method of predicting credit losses. The determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an exercise of judgment. Similarly, the determination of the adequacy of the ACL can be made only on a subjective basis. Our management believes that the ACL at December 31, 2021 was adequate to absorb expected losses from loans and other financial instruments in the portfolio at that date.

Non-interest income from other investments for the year ended December 31, 2021 was positively impacted by the sale of an equity interest in a merchant banking investment held by one of our non-bank subsidiaries.

The decrease is primarily due to our continued employee compensation and benefits expense reductions, and is primarily being driven by efforts to right-size and closely manage our workforce commensurate with decreased activities in our branches arising from the COVID-19 pandemic while ensuring that we are able to continue to serve our customers. We continue to actively monitor and manage our controllable non-interest expenses and continue to develop operating efficiencies through a variety of methods, with the ultimate goal of ensuring we align non-interest expenses with our operations and revenue streams. Total non-interest expense has decreased by approximately 15.0% or $46.5 million, over the two-year period ending December 31, 2021, primarily driven by decreases in our employee compensation and benefit plans expenses, professional fees and other general operating expenses. Non-interest expense for the year ended December 31, 2020 decreased by 9.2% compared to the same period of 2019 for similar reasons. These expense reductions have 12 occurred because management acted quickly and precisely at the onset of the pandemic to mitigate the impact of reduced interest rates and business activities. Effects of Inflation The principal component of earnings is net interest income, which is affected by changes in the level of interest rates. Changes in rates of inflation affect interest rates. It is difficult to precisely measure the impact of inflation on net interest income because it is not possible to accurately differentiate between increases in net interest income resulting from inflation and increases resulting from increased business activity. Inflation also raises costs of operations, primarily those of employment and services.

Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. government. Investments in residential mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in 2008 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae or Freddie Mac are rated consistently as AAA rated securities. 13 Loans The following table shows the amounts of loans outstanding as of December 31, 2021, which based on remaining scheduled repayments of principal are due in the years indicated.

We rely primarily on our high-quality customer service, sales programs, customer referrals and advertising to attract and retain these deposits. Deposits provide the primary source of funding for our lending and investment activities, and the interest paid for deposits must be managed carefully to control the level of interest expense. Deposits at December 31, 2021 were $12,617,877,000, an increase of 17.7% from $10,721,860,000 at December 31, 2020. Deposits during the current economic environment have increased as customers have received proceeds from CARES Act programs, such as stimulus payments and PPP loan proceeds, and presumably decided to save and preserve cash instead of spending during these uncertain times. Other Borrowed Funds Other borrowed funds include FHLB borrowings which are long-term borrowings issued by the FHLB of Dallas and the FHLB of Topeka at the market price offered at the time of funding. These borrowings are secured by residential 16 mortgage-backed investment securities and a portion of our loan portfolio. At December 31, 2021, other borrowed funds totaled $436,138,000, a slight decrease from $436,327,000 at December 31, 2020.

Liquidity and Capital Resources Liquidity The maintenance of adequate liquidity provides our Subsidiary Banks with the ability to meet potential depositor withdrawals, provide for customer credit needs, maintain adequate statutory reserve levels and take full advantage of high-yield investment opportunities as they arise. Liquidity is afforded by access to financial markets and by holding appropriate amounts of liquid assets. Our Subsidiary Banks derive their liquidity largely from deposits of individuals and business entities. Other important funding sources for our Subsidiary Banks during 2021 and 2020 were borrowings from the FHLB, securities sold under repurchase agreements and large certificates of deposit, requiring management to closely monitor its asset/liability mix in terms of both rate sensitivity and maturity distribution. Our Subsidiary Banks have had a long-standing relationship with the FHLB and keep open, unused, lines of credit in order to fund liquidity needs. In the event that the FHLB indebtedness is not renewed, the repayment of the outstanding indebtedness would more than likely be repaid through proceeds generated from the sales of unpledged available-for-sale securities. We maintain a sizable, high quality investment portfolio to provide significant liquidity. These securities can be sold or sold under agreements to repurchase, to provide immediate liquidity. As in the past, we will continue to monitor the volatility and cost of funds in an attempt to match maturities of rate-sensitive assets and liabilities and respond accordingly to anticipated fluctuations in interest rates over reasonable periods of time. Asset/Liability Management Our funds management policy has as its primary focus the measurement and management of the Subsidiary Banks’ earnings at risk in the face of rising or falling interest rate forecasts. The earliest and most simplistic concept of earnings at risk measurement is the gap report, which is used to generate a rough estimate of the vulnerability of net interest income to changes in market rates as implied by the relative re-pricings of assets and liabilities. The gap report calculates the difference between the amounts of assets and liabilities re-pricing across a series of intervals in time, with emphasis typically placed on the one-year period. This difference, or gap, is usually expressed as a percentage of total assets. If an excess of liabilities over assets matures or re-prices within the one-year period, the statement of condition is said to be negatively gapped. This condition is sometimes interpreted to suggest that an institution is liability-sensitive, indicating that earnings would suffer from rising rates and benefit from falling rates. If a surplus of assets over liabilities occurs in the one-year time frame, the statement of condition is said to be positively gapped, suggesting a condition of asset sensitivity in which earnings would benefit from rising rates and suffer from falling rates. 17 The gap report thus consists of an inventory of dollar amounts of assets and liabilities that have the potential to mature or re-price within a particular period. The flaw in drawing conclusions about interest rate risk from the gap report is that it takes no account of the probability that potential maturities or re-pricings of interest-rate-sensitive accounts will occur, or at what relative magnitudes. Because simplicity, rather than utility, is the only virtue of gap analysis, financial institutions increasingly have either abandoned gap analysis or accorded it a distinctly secondary role in managing their interest-rate risk exposure. The net interest rate sensitivity at December 31, 2021, is illustrated in the following table. This information reflects the balances of assets and liabilities whose rates are subject to change. As indicated in the table below, we are asset sensitive through all of the time periods illustrated. The table shows the sensitivity of the statement of condition at one point in time and is not necessarily indicative of the position at future dates.

In particular, the fundamental, but often unstated, assumption of the gap approach that every statement of condition item that can re-price will do so to the full extent of any movement in market interest rates is taken into consideration in income simulation analysis. 18 Accordingly, income simulation analysis captures not only the potential of assets and liabilities to mature or re-price, but also the probability that they will do so. Moreover, income simulation analysis focuses on the relative sensitivities of these balance sheet items and projects their behavior over an extended period of time in a motion picture rather than snapshot fashion. Finally, income simulation analysis permits management to assess the probable effects on balance sheet items not only of changes in market interest rates, but also of proposed strategies for responding to such changes. We and many other institutions rely primarily upon income simulation analysis in measuring and managing exposure to interest rate risk. We have established guidelines for acceptable volatility of projected net interest income on the income simulation analysis and the guidelines are reviewed at least annually. As of December 31, 2021, in rising rate scenarios of +100, +200, +300 and +400 basis points, the guidelines established by management require that the net interest income not vary by more than minus 15%, 15%, 15%, and 20%, respectively, for the first 12-month period projected. Given the current low interest rate environment, no downward rate shifts were modeled in our income simulations. At December 31, 2021, the income simulations show that a rate shift of +100, +200, +300 and +400 basis points in interest rates up will vary projected net interest income for the coming 12-month period by +15.6%, +30.47%, +45.95%, and +61.42%, respectively. The basis point shift in interest rates is a hypothetical rate scenario used to calibrate risk and does not necessarily represent management’s current view of future market developments. We believe that we are properly positioned for a potential interest rate increase or decrease. All the measurements of risk described above are made based upon our business mix and interest rate exposures at the particular point in time. The exposure changes continuously as a result of our ongoing business and our risk management initiatives. While management believes these measures provide a meaningful representation of our interest rate sensitivity, they do not necessarily take into account all business developments that have an effect on net income, such as changes in credit quality or the size and composition of the statement of condition. Our principal sources of liquidity and funding dividends from subsidiaries and borrowed funds, with such funds being used to finance our cash flow requirements. We closely monitor the dividend restrictions and availability from our Subsidiary Banks as disclosed in Note 20 to the Consolidated Financial Statements. At December 31, 2021, the aggregate amount legally available to be distributed to us from our Subsidiary Banks as dividends was approximately $1,066,000,000, assuming that each Subsidiary Bank continues to be classified as “well-capitalized” under the applicable regulations in effect at December 31, 2021. The restricted capital (capital and surplus) of our Subsidiary Banks was approximately $1,225,260,000 as of December 31, 2021. The undivided profits of our Subsidiary Banks were approximately $1,394,877,000 as of December 31, 2021. At December 31, 2021, we had outstanding $436,138,000 in other borrowed funds and $134,642,000 in junior subordinated deferrable interest debentures. In addition to borrowed funds and dividends, we have a number of other available alternatives to finance the growth of our Subsidiary Banks as well as future growth and expansion. Capital We maintain an adequate level of capital as a margin of safety for our depositors and shareholders. At December 31, 2021, shareholders’ equity was $2,308,481,000 compared to $2,177,998,000 at December 31, 2020, an increase of $130,483,000, or 6.2%. Shareholders’ equity increased primarily due to the retention of earnings, offset by the payment of cash dividends to shareholders and repurchases of our common stock in the form of treasury stock. The accumulated other comprehensive income is not included in the calculation of regulatory capital ratios. During 1990, the FRB adopted a minimum leverage ratio of 3% for the most highly rated bank holding companies and at least 4% to 5% for all other bank holding companies. Our leverage ratio (defined as shareholders’ equity plus eligible trust preferred securities issued and outstanding less goodwill and certain other intangibles divided by average quarterly assets) was 13.94% at December 31, 2021 and 14.92% at December 31, 2020. The core deposit intangibles and goodwill of $282,532,000 as of December 31, 2021, are deducted from the sum of core capital elements when determining our capital ratios. 19 The FRB has adopted risk-based capital guidelines which assign risk weightings to assets and off-balance sheet items. The guidelines also define and set minimum capital requirements (risk-based capital ratios). Under the final 1992 rules, all banks are required to have Tier 1 capital of at least 4.0% of risk-weighted assets and total capital of 8.0% of risk-weighted assets. Tier 1 capital consists principally of shareholders’ equity plus trust preferred securities issued and outstanding less goodwill and certain other intangibles, while total capital consists of Tier 1 capital, certain debt instruments and a portion of the reserve for loan losses. In order to be deemed well-capitalized pursuant to the regulations, an institution must have a total risk-weighted capital ratio of 10%, a Tier 1 risk-weighted ratio of 8% and a Tier 1 leverage ratio of 5%. We had risk-weighted Tier 1 capital ratios of 21.59% and 20.25% and risk weighted total capital ratios of 22.73% and 21.4% as of December 31, 2021 and 2020, respectively, which are well above the minimum regulatory requirements and exceed the well-capitalized ratios (see Note 19 to Notes to Consolidated Financial Statements). In July 2013, the Federal Deposit Insurance Corporation (“FDIC”) and other regulatory bodies established a new, comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both the quantity and quality of capital held by banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various Dodd-Frank related capital provisions. Consistent with the Basel international framework, the rules include a minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% and a CET1 capital conservation buffer of 2.5% of risk-weighted assets. The capital conservation buffer began phasing-in on January 1, 2016 at .625% and increased each year until January 1, 2019, when we were required to have a 2.5% capital conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the rules emphasize CET1 capital and implements strict eligibility criteria for regulatory capital instruments. The rules also improve the methodology for calculating risk-weighted assets to enhance risk sensitivity. The rules were subject to a four-year phase in period for mandatory compliance and we were required to begin to phase in the rules beginning on January 1, 2015. We believe that as of December 31, 2021, we meet all fully phased-in capital adequacy requirements. On November 21, 2017, the OCC, the Federal Reserve and the FDIC finalized a proposed rule that extends the current treatment under the regulatory capital rules for certain regulatory capital deductions and risk weights and certain minority interest requirements, as they apply to banking organizations that are not subject to the advanced approaches capital rules. Effective January 1, 2018, the rule also pauses the full transition to the Basel III treatment of mortgage servicing assets, certain deferred tax assets, investments in the capital of unconsolidated financial institutions and minority interests. The agencies are also considering whether to make adjustments to the capital rules in response to CECL (the FASB Standard relating to current expected credit loss) and its potential impact on regulatory capital. On December 7, 2017, the Basel Committee on Banking Supervision unveiled the latest round of its regulatory capital framework, commonly called “Basel IV.” The framework makes changes to the capital framework first introduced as “Basel III” in 2010. The committee targeted 2022-2027 as the timeframe for implementation by regulators in individual countries, including the U.S. federal bank regulatory agencies (after notice and comment). Junior Subordinated Deferrable Interest Debentures We have formed five statutory business trusts under the laws of the State of Delaware, for the purpose of issuing trust preferred securities. These statutory business trusts (the “Trusts”) have each issued Capital and Common Securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) that we issued. As of December 31, 2021 and December 31, 2020, the principal amount of debentures outstanding totaled $134,642,000. The Debentures are subordinated and junior in right of payment to all of our present and future senior indebtedness (as defined in the respective indentures), and are pari passu with one another. The interest rate payable on, and the payment terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive quarterly periods on Trusts VIII, IX, X, XI and XII. If interest payments on any of the Debentures are deferred, distributions 20 on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption prior to maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory bodies. For financial reporting purposes, the Trusts are treated as investments and not consolidated in the consolidated financial statements. Although the Capital Securities issued by each of the Trusts are not included as a component of shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 capital up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that exceeds the 25% threshold would qualify as Tier 2 capital. At December 31, 2021 and December 31, 2020, the total $134,642,000 of the Capital Securities outstanding qualified as Tier 1 capital.

Critical Accounting Policies We have established various accounting policies which govern the application of accounting principles in the preparation of our consolidated financial statements. The significant accounting policies are described in the Notes to the Consolidated Financial Statements. Certain accounting policies involve significant subjective judgments and assumptions by management which have a material impact on the carrying value of certain assets and liabilities; management considers such accounting policies to be critical accounting policies. We consider our estimated ACL as a policy critical to the sound operations of our Subsidiary Banks. We adopted the provisions of Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – Credit Losses,” on January 1, 2020. ASU 2016-13 replaces the long-standing incurred loss model with an expected credit loss model that recognizes credit losses over the life of a financial asset. Expected credit losses capture historical information, current conditions, and reasonable and supportable forecasts of future conditions. The ACL is deducted from the amortized cost of an instrument to present the net amount expected to be collected on the financial asset. Our ACL primarily consists of the aggregate ACL estimates of our Subsidiary Banks. The estimates are established through charges to operations in the form of charges to provisions for credit loss expense. Loan losses or recoveries are charged or credited directly to the ACL. The ACL of each Subsidiary Bank is maintained at a level considered appropriate by management, based on estimated current expected credit losses in the current loan portfolio, including information about past events, current conditions and reasonable and supportable forecasts. The estimation of the ACL is based on a loss-rate methodology that measures lifetime losses on loan pools that have similar risk characteristics. Loans that do not have similar risk characteristics are evaluated on an individual basis. The segmentation of the loan portfolio into pools requires a balancing process between capturing similar risk characteristics and containing sufficient loss history to provide meaningful results. Our segmentation starts at the general loan category with further sub-segmentation based on collateral types that may be of meaningful size and/or may contain 21 sufficient differences in risk characteristics based on management’s judgement that would warrant further segmentation. The general loan categories along with primary risk characteristics used in our calculation are as follows: Commercial and industrial loans. This category includes loans extended to a diverse array of businesses for working capital or equipment purchases. These loans are mostly secured by the collateral pledged by the borrower that is directly related to the business activities of the company such as equipment, accounts receivable and inventory. The borrower’s abilities to generate revenues from equipment purchases, collect accounts receivable, and to turn inventory into sales are risk factors in the repayment of the loan. A small portion of this loan category is related to loans secured by oil & gas production and loans secured by aircraft. Construction and land development loans. This category includes the development of land from unimproved land to lot development for both residential and commercial use and vertical construction across residential and commercial real estate classes. These loans carry risk of repayment when projects incur cost overruns, have an increase in the price of construction materials, encounter zoning, entitlement and environmental issues, or encounter other factors that may affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively impacted when the market experiences a deterioration in the value of real estate. Risks specifically related to 1-4 family development loans also include mortgage rate risk and the practice by the mortgage industry of more restrictive underwriting standards, which inhibits the buyer from obtaining long term financing creating excessive housing and lot inventory in the market. Commercial real estate loans. This category includes loans secured by farmland, multifamily properties, owner occupied commercial properties, and non-owner occupied commercial properties. Owner occupied commercial properties include warehouses often along the border for import/export operations, office space where the borrower is the primary tenant, restaurants and other single-tenant retail. Non-owner occupied commercial properties include hotels, retail centers, office and professional buildings, and leased warehouses. These loans carry risk of repayment when market values deteriorate, the business experiences turnover in key management, the business has an inability to attract or keep occupancy levels stable, or when the market experiences an exit of a specific business type that is significant to the local economy, such as a manufacturing plant. 1-4 family mortgages. This category includes both first and second lien mortgages for the purpose of home purchases or refinancing of existing mortgage loans. A small portion of this loan category is related to home equity lines of credits, lots purchases, and home construction. Loan repayments may be affected by unemployment or underemployment and deteriorating market values of real estate. Consumer loans. This category includes deposit secured, vehicle secured, and unsecured loans, including overdrafts, made to individuals. Repayment is primarily affected by unemployment or underemployment. The loan pools are further broken down using a risk-based segmentation based on internal classifications for commercial loans and past due status for consumer mortgage loans. Non-mortgage consumer loans are evaluated as one segment. On a weekly basis, commercial loan past due reports are reviewed by the credit quality committee to determine if a loan has any potential problems and if a loan should be placed on our internal Watch List report. Additionally, our credit department reviews the majority of our loans for proper internal classification purposes regardless of whether they are past due and segregates any loans with potential problems for further review. The credit department will discuss the potential problem loans with the servicing loan officers to determine any relevant issues that were not discovered in the evaluation. Also, an analysis of loans that is provided through examinations by regulatory authorities is considered in the review process. After the above analysis is completed, we will determine if a loan should be placed on an internal Watch List report because of issues related to the analysis of the credit, credit documents, collateral and/or payment history. Our internal Watch List report is segregated into the following categories: (i) Pass, (ii) Economic Monitoring, (iii) Special Review, (iv) Watch List—Pass, or (v) Watch List—Substandard, and (vi) Watch List—Doubtful. The loans placed in the Special Review category and lower rated credits reflect our opinion that the loans reflect potential weakness which require monitoring on a more frequent basis. Credits in those categories are reviewed and discussed on a regular basis, no less frequently than quarterly, with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the Watch List—Pass category and lower rated credits reflect our opinion that the credit 22 contains weaknesses which represent a greater degree of risk, which warrant “extra attention.” Credits in this category are reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the Watch List—Substandard category are considered to be potentially inadequately protected by the current sound worth and debt service capacity of the borrower or of any pledged collateral. These credit obligations, even if apparently protected by collateral value, have shown defined weaknesses related to adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and interest. Furthermore, there is the possibility that we may sustain some future loss if such weaknesses are not corrected. The loans placed in the Watch List—Doubtful category have shown defined weaknesses and it is likely, based on current information and events, that we will be unable to collect all principal and/or interest amounts contractually due. Watch List—Doubtful loans are placed on non-accrual when they are moved to that category. For the purposes of the ACL, in order to maintain segments with sufficient history for meaningful results, the credits in the Pass and Economic Monitoring categories are aggregated, the credits in the Special Review and Watch List— Pass credits are aggregated, and the credits in the Watch List—Substandard category remain in their own segment. For loans that are classified as Watch List—Doubtful, management evaluates these credits in accordance with ASC 310-10, “Receivables,” and, if deemed necessary, a specific reserve is allocated to the loan. The specific reserve allocated under ASC 310-10, is based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the loan’s observable market price; or (iii) net realizable value of the fair value of the collateral if the loan is collateral dependent. Substantially all of our loans evaluated as Watch List—Doubtful under ASC 310-10 are measured using the fair value of collateral method. In rare cases, we may use other methods to determine the specific reserve of a loan under ASC 310-10 if such loan is not collateral dependent. Within each collectively evaluated pool, the robustness of the lifetime historical loss-rate is evaluated and, if needed, is supplemented with peer loss rates through a model risk adjustment. Certain qualitative loss factors are then evaluated to incorporate management’s two-year reasonable and supportable forecast period followed by a reversion to the pool’s average lifetime loss-rate. Those qualitative loss factors are: (i) trends in portfolio volume and composition, (ii) volume and trends in classified loans, delinquencies, non-accruals and TDR’s, (iii) concentration risk, (iv) trends in underlying collateral value, (v) changes in policies, procedures, and strategies, and (vi) economic conditions. Qualitative factors also include potential losses stemming from operational risk factors arising from fraud, natural disasters, pandemics and geopolitical events. Should any of the factors considered by management in evaluating the adequacy of the ACL change, our estimate could also change, which could affect the level of future credit loss expense. We have elected to not measure an ACL for accrued interest receivable given our timely approach in identifying and writing off uncollectible accrued interest. An ACL for off-balance sheet exposure is derived from a projected usage rate of any unfunded commitment multiplied by the historical loss rate, plus model risk adjustment, if any, of the on- balance sheet loan pools. Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and the estimate based on qualitative current conditions and reasonable and supportable two-year forecasted data. Our methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable and supportable forecasts. Should any of the factors considered by management in evaluating the adequacy of the estimate for current expected credit losses change, our estimate of current expected credit losses could also change, which could affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in interest rates and the view of regulatory authorities towards loan classifications.

Stock Repurchase Program In April 2009, the Board of Directors re-established a formal stock repurchase program that authorized the repurchase of up to $40 million of common stock within the following 12 months. Annually since then, including on March 2, 2021, the Board of Directors extended the repurchase program to purchase up to $50 million of common stock during the 12 month period commencing on March 17, 2021. Shares of common stock may be purchased from time to time on the open market or through privately negotiated transactions. Shares purchased under this program will be held in treasury for reissue for various corporate purposes, including employee compensation plans. During the fourth quarter of 2021, the Board of Directors adopted a Rule 10b5-1 trading plan, and intends to adopt additional Rule 10b5-1 trading plans, that will allow us to purchase shares of our common stock during certain trading blackout periods when we ordinarily would not be in the market due to trading restrictions in our insider trading policy. During the term of a Rule 10b5-1 trading plan, purchases of common stock are automatic to the extent the conditions of the plan’s trading instructions are met. Shares purchased under the Rule 10b5-1 trading plan will be held in treasury for reissue for various corporate purposes, including employee stock compensation plans. As of February 18, 2022, a total of 12,285,386 shares had been repurchased under all programs at a cost of $357,771,000. We are not obligated to purchase shares under our stock repurchase program outside of its Rule 10b5-1 trading plan. Except for repurchases in connection with the administration of an employee benefit plan in the ordinary course of business and consistent with past practices, common stock repurchases are only conducted under publicly announced repurchase programs approved by the Board of Directors. The following table includes information about common stock share repurchases for the quarter ended December 31, 2021. 24 Total Number of Shares Purchased as Total Number Price Paid Average Part of a Publicly- of Shares Purchased Per Share Announced Program Approximate Dollar Value of Shares Available for Repurchase(1) October 1 – October 31, 2021 . . . . . . . . . . . . . . . . . . . . . . . . . .

In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2021, in conf ormity with accounting principles generally accepted in the United States of America. We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2021, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 24, 2022 expressed an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting. Basis for Opinion These f inancial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are f ree of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or f raud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates. 27 Allowance for Credit Losses As described in Note 4 of the consolidated financial statements, the Company established an allowance f or credit losses totaling $110,374,000 as of December 31, 2021. The allowance for credit losses is derived from a loss-rate methodology that measures lifetime losses on loan pools that have similar risk characteristics. Loans that do not have similar risk characteristics are evaluated on an individual basis. The segmentation of the loan portfolio into pools requires a balancing process between capturing similar risk characteristics and sufficient loss history to provide relevant results. Loan pools are further broken down using a risk-based segmentation based on internal classifications of credit quality. Within each loan pool, the lifetime historical loss-rate is evaluated and, if needed, is supplemented with peer loss rates through a model risk adjustment. Certain qualitative factors are applied at the loan pool level to incorporate management’s two-year forecast period followed by a reversion to the pool’s average lifetime loss-rate. Those qualitative factors include: (i) trends in portfolio volume and composition, (ii) volume and trends in classified loans, delinquencies, non-accruals and troubled debt restructurings (TDR’s), (iii) concentration risk, (iv) trends in underlying collateral value, (v) changes in policies, procedures, and strategies, (vi) economic conditions, and (vii) operational and other risk factors to capture potential losses arising f rom fraud, natural disasters, pandemics, and geopolitical events. We identif ied the qualitative factor component of the allowance for credit losses as a critical audit matter. Auditing management’s estimate of the qualitative factors required a high degree of auditor judgment due to the nature of the adjustments and the subjectivity in judgments applied by management in forming them. Our audit procedures related to the Company’s qualitative factors included, the following, among others: We obtained an understanding of the relevant controls related to the allowance for credit losses, including the qualitative factors, and tested such controls for design and operating effectiveness, including controls related to management’s review of the qualitative factors and approval of the allowance for credit losses calculation. We evaluated the appropriateness and consistency of management’s methods and assumptions used to determine qualitative factors by (1) evaluating management’s identification and quantification of qualitative factors; (2) testing the completeness and accuracy of data and information used in calculating the components of the qualitative factors; (3) evaluating the reasonableness, directional consistency, and magnitude of the quantification of the qualitative factors; and (4) reviewing subsequent events and considering their impact on judgments applied in forming the qualitative factor component of the allowance for credit losses as of the consolidated balance sheet date. We have served as the Company’s auditor since 2007.

The following is a description of the more significant of those policies. Consolidation and Basis of Presentation Our consolidated financial statements include the accounts of the International Bancshares Corporation, its wholly-owned Subsidiary Banks and its wholly-owned non-bank subsidiaries, IBC Trading Company, Premier Tierra Holdings, Inc., IBC Charitable and Community Development Corporation, IBC Capital Corporation and Diamond Beach Holdings, LLC. All significant inter-company balances and transactions have been eliminated in consolidation. We, through our Subsidiary Banks, are primarily engaged in the business of banking, including the acceptance of checking and savings deposits and the making of commercial, real estate, personal, home improvement, automobile and other installment and term loans. Our primary markets are north, south, central, and southeast Texas and the state of Oklahoma. Each of our Subsidiary Banks is very active in facilitating international trade along the United States border with Mexico and elsewhere. Although our loan portfolio is diversified, the ability of our debtors to honor their contracts is primarily dependent upon the economic conditions in our trade area. In addition, the investment portfolio is directly impacted by fluctuations in market interest rates. We are subject to the regulations of certain federal agencies as well as the Texas Department of Banking and the Oklahoma Department of Banking and undergo periodic examinations by those regulatory authorities. Such agencies may require certain standards or impose certain limitations based on their judgments or changes in law and regulations. We own one insurance-related subsidiary, IBC Insurance Agency, Inc., a wholly owned subsidiary of our Subsidiary Bank, International Bank of Commerce, Laredo. The insurance-related subsidiary does not conduct underwriting activities. The preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the dates of the statement of condition and income and expenses for the periods. Actual results could differ significantly from those estimates. Material estimates that are particularly susceptible to significant changes in the near-term relate to the determination of the allowance for credit losses (“ACL”). Subsequent Events We have evaluated all events or transactions that occurred through the date we issued these financial statements. During this period, we did not have any material recognizable or non-recognizable subsequent events. Investment Securities We classify debt securities into one of these categories: held-to-maturity, available-for-sale, or trading. Such classifications are reassessed for appropriate classification at each reporting date. Securities that are intended and expected to be held until maturity are classified as “held-to-maturity” and are carried at amortized cost for financial statement reporting. Securities that are not positively expected to be held until maturity, but are intended to be held for an indefinite period of time are classified as “available-for-sale” or “trading” and are carried at their fair value. Unrealized holding gains and losses are included in net income for those securities classified as “trading”, while unrealized holding gains and losses related to those securities classified as “available-for-sale” are excluded from net income and reported net of tax as other comprehensive income (loss) and in shareholders’ equity as accumulated other comprehensive income (loss) until realized. Unrealized gains and losses related to equity securities with readily determinable fair values are included in net income. In accordance with ASU 2016-13, which we adopted on January 1, 2020, available-for-sale and held-to-maturity debt securities in an unrealized loss position must be evaluated for the underlying cause of the loss. In the event that the deterioration in value is attributable to credit related reasons, then the amount of credit-related impairment would be recorded as a charge to our ACL with subsequent changes in the amount of impairment, up or down, also recorded through 37 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) our ACL. The exception to this process will occur if we intend to sell an impaired available-for-sale debt security or if we will more likely than not be required to sell a credit impaired available-for-sale debt security prior to the value recovering to the security’s amortized cost. In those situations, the entire credit-related impairment amount would be required to be recognized in earnings. We have evaluated the debt securities classified as available-for-sale and held-to-maturity at December 31, 2021 and have determined that no debt securities in an unrealized loss position are arising from credit related reasons and have therefore not recorded any allowances for debt securities in our ACL for the periods. We did not maintain any trading securities during the three-year period ended December 31, 2021. Mortgage-backed securities held at December 31, 2021 and 2020 represent participating interests in pools of long-term first mortgage loans originated and serviced by the issuers of the securities. Mortgage-backed securities are either issued or guaranteed by the U.S. government or its agencies including Freddie Mac, Fannie Mae, Ginnie Mae or other non-government entities. Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U. S. government. Investments in residential mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in 2008 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae or Freddie Mac are rated consistently as AAA rated securities. Market interest rate fluctuations can affect the prepayment speed of principal and the yield on the security. Premiums and discounts are amortized using the level yield or “interest method” over the terms of the securities. Declines in the fair value of held-to-maturity and available-for sale-securities below their cost that are deemed to be other than temporary are reflected in earnings as realized losses. In determining whether other-than-temporary impairment exists, management considers many factors, including (i) the length of time and the extent to which the fair value has been less than cost, (ii) the financial condition and near-term prospects of the issuer, and (iii) our intent to hold and our determination of whether we will more likely than not be required to sell the security prior to a recovery in fair value. If we determine that (i) we intend to sell the security or (ii) it is more likely than not that we will be required to sell the security before it’s anticipated recovery, the other-than-temporary impairment that is recognized in earnings is equal to the difference between the fair value of the security and our amortized cost of the security. If we determine that we (i) do not intend to sell the security and (ii) we will not be more likely than not required to sell the security before it’s anticipated recovery, the other-than-temporary impairment is segregated into its two components (i) the amount of impairment related to credit loss and (ii) the amount of impairment related to other factors. The difference between the present value of the cash flows expected to be collected and the amortized cost is the credit loss recognized through earnings and an adjustment to the cost basis of the security. The amount of impairment related to other factors is included in other comprehensive income (loss). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method. Equity Securities Equity securities with readily determinable fair values at December 31, 2021 and December 31, 2020 consist primarily of Community Reinvestment Act funds. Unrealized gains and losses on the equity securities are recognized in net income. Provision and Allowance for Credit Losses We adopted the provisions of Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – Credit Losses,” on January 1, 2020. ASU 2016-13 replaces the long-standing incurred loss model with an expected credit loss model that recognizes credit losses over the life of a financial asset. Expected credit losses capture historical information, current conditions, and reasonable and supportable forecasts of future conditions. The ACL is deducted from the amortized cost of an instrument to present the net amount expected to be collected on the financial asset. Our ACL primarily consists of the aggregate ACL estimates of our Subsidiary Banks. The estimates are established through charges to operations in the form of charges to provisions for credit loss expense. Loan losses or recoveries are charged or credited directly to the ACL. The ACL of each Subsidiary Bank is maintained at a level considered appropriate by management, based on estimated current expected credit losses in the current loan portfolio, including information about past events, current conditions and reasonable and supportable forecasts. 38 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and the estimate based on qualitative current conditions and reasonable and supportable two-year forecasted data. Our methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable and supportable forecasts. Should any of the factors considered by management in evaluating the adequacy of the estimate for current expected credit losses change, our estimate of current expected credit losses could also change, which could affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in interest rates and the view of regulatory authorities towards loan classifications. We believe that the allowance for probable loan losses is adequate. The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial, financial and agricultural or real estate loans are generally considered by management to represent a loss, in whole or part, (i) when an exposure beyond any collateral coverage is apparent, (ii) when no further collection of the portion of the loan so exposed is anticipated based on actual results, (iii) when the credit enhancements, if any, are not adequate, and (iv) when the borrower’s financial condition would indicate so. Generally, unsecured consumer loans are charged-off when 90 days past due. Loans Loans are reported at the principal balance outstanding, net of unearned discounts. Interest income on loans is reported on an accrual basis. Loan fees and costs associated with originating the loans are accreted or amortized over the life of the loan using the interest method. We originate mortgage loans that may subsequently be sold to an unaffiliated third party. The loans are not securitized and if sold, are sold without recourse. Loans held for sale are carried at cost and the principal amount outstanding is not significant to the consolidated financial statements. Doubtful Loans Doubtful loans are those loans where it is probable that all amounts due according to contractual terms of the loan agreement will not be collected. Doubtful loans are measured based on (1) the present value of expected future cash flows discounted at the loan’s effective interest rate; (2) the loan’s observable market price; or (3) the fair value of the collateral if the loan is collateral dependent. Substantially all our doubtful loans are measured at the fair value of the collateral. In limited cases, we may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent. 39 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Troubled Debt Restructured Loans Troubled debt restructured loans (“TDR”) are those loans where, for reasons related to a borrower’s difficulty to repay a loan, we grant a concession to the borrower that we would not normally consider in the normal course of business. In accordance with interagency guidance issued in March 2020, certain short-term deferrals are not considered troubled debt restructurings. The original terms of the loan are modified or restructured. The terms that may be modified include a reduction in the original stated interest rate, an extension of the original maturity of the loan, a renewal of the loan at an interest rate below current market rates, a reduction in the principal amount of debt outstanding, a reduction in accrued interest or deferral of interest payments. A loan classified as a TDR is classified as a doubtful loan and included in the doubtful loan totals. A TDR loan may be returned to accrual status when the loan is brought current, has performed in accordance with the restructured terms for a reasonable period of time, is at the current market rate, and the ultimate collectability of the outstanding principal and interest is no longer questionable, however, although those loans may be placed back on accrual status, they will continue to be classified as doubtful. Consistent with regulatory guidance, a TDR loan that is subsequently modified, but has shown sustained performance and classification as a TDR, will be removed from TDR status provided that the modified terms were market-based at the time of modification. Non-Accrual Loans The non-accrual loan policy of our Subsidiary Banks is to discontinue the accrual of interest on loans when management determines that it is probable that future interest accruals will be un-collectible. As it relates to consumer loans, management charges-off those loans when the loan is contractually 90 days past due. Under special circumstances, a consumer or non-consumer loan may be more than 90 days delinquent as to interest or principal and not be placed on non-accrual status. This situation generally results when a Subsidiary Bank has a borrower who is experiencing financial difficulties, but not to the extent that requires a restructuring of indebtedness. The majority of this category is composed of loans that are considered to be adequately secured and/or for which there are expected future payments. When a loan is placed on non-accrual status, any interest accrued, not paid is reversed and charged to operations against interest income. As it relates to non-consumer loans that are not 90 days past due, management will evaluate each of these loans to determine if placing the loan on non-accrual status is warranted. Interest income on non-accrual loans is recognized only to the extent payments are received or when, in management’s opinion, the debtor’s financial condition warrants reestablishment of interest accruals. Other Real Estate Owned and Repossessed Assets Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such property (as determined by independent appraisal). Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the ACL, if necessary. Any subsequent write-downs are charged against other non-interest expense through a valuation allowance. Other real estate owned totaled approximately $35,332,000 and $60,487,000 at December 31, 2021 and 2020, respectively. Other real estate owned is included in other assets. Repossessed assets consist primarily of non-real estate assets acquired by foreclosure. Prior to foreclosure, the value of the underlying loan is written down to the fair value of the asset to be repossessed by a charge to the ACL, if necessary. Repossessed assets are included in other assets on the consolidated financial statements and totaled approximately $4,798,000 and $5,779,000 at December 31, 2021 and 2020, respectively. Bank Premises and Equipment Bank premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed on straight-line and accelerated methods over the estimated useful lives of the assets. Repairs and maintenance are charged to operations as incurred and expenditures for renewals and betterments are capitalized. We primarily own all the property we occupy, with the exception of certain branches operating in grocery store or retail shopping centers and certain ATM locations, which are all under operating leases as classified under guidance prior to the issuance of ASU 2016-02, “Leases.” 40 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Other Investments Other investments include equity investments in non-financial companies, as well as equity securities with no readily determinable fair market value. Equity investments are accounted for using the equity method of accounting. Equity securities with no readily determinable fair value are accounted for using the cost method. Revenue Recognition Our revenue is primarily comprised of net interest income on financial assets and liabilities, which are excluded from the scope of ASU No. 2014-09 to ASC 606, “Revenue from Contracts with Customers.” The remaining non-interest revenue streams were identified and then analyzed under the provisions of the update, to: (i) identify the contract, (ii) identify the performance obligation, (iii) determine the transaction price, (iv) allocate the transaction price to the performance obligations, and (v) recognize revenue when the performance obligation was satisfied. Our non-interest revenue contracts with customers are primarily short term and our performance obligation is satisfied at a single point in time, typically within a single period. No changes to our existing methods for recognizing revenue were made as a result of the accounting standards update. Income Taxes Deferred income tax assets and liabilities are determined using the asset and liability method. Under this method, the net deferred tax asset or liability is determined based on the tax effects of the differences between the book and tax basis of the various balance sheet assets and liabilities and gives current recognition to changes in tax rates and laws. We file a consolidated federal income tax return with our subsidiaries. Recognition of deferred tax assets is based on management’s assessment that the benefit related to certain temporary differences, tax operating loss carry forwards, and tax credits are more likely than not to be realized. A valuation allowance is recorded for the amount of the deferred tax items for which it is more likely than not that the tax benefits will not be realized. We evaluate uncertain tax positions at the end of each reporting period. We may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefit recognized in the financial statements from any such a position is measured based on the largest benefit that has a greater than fifty percent likelihood of being realized upon ultimate settlement. As of December 31, 2021 and 2020, respectively, after evaluating all uncertain tax positions, we have recorded no liability for unrecognized tax benefits at the end of the reporting period. We would recognize any interest accrued on unrecognized tax benefits as other interest expense and penalties as other non-interest expense. During the years ended December 31, 2021, 2020 and 2019, we recognized no interest expense or penalties related to uncertain tax positions. We file consolidated tax returns in the U.S. Federal jurisdiction and various state jurisdictions. We are no longer subject to U.S. federal or state income tax examinations by tax authorities for years before 2018. Stock Options Compensation expense for stock awards is based on the market price of the stock on the measurement date, which is generally the date of grant, and is recognized ratably over the service period of the award. The fair value of stock options granted was estimated using the Black-Sholes-Merton option-pricing model. This model was developed for use in estimating the fair value of publicly traded options that have no vesting restrictions and are fully transferable. Additionally, the model requires the input of highly subjective assumptions. Because our employee stock options have characteristics significantly different from those of publicly traded options, and because changes in the subjective input assumptions can materially affect the fair value estimate, in management’s opinion, the Black-Scholes-Merton option-pricing model does not necessarily provide a reliable single measure of the fair value of our stock options. 41 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Net Income Per Share Basic Earnings Per Share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding. The computation of diluted EPS assumes the issuance of common shares for all dilutive potential common shares outstanding during the reporting period. The dilutive effect of stock options is considered in earnings per share calculations, if dilutive, using the treasury stock method. Goodwill and Identified Intangible Assets Goodwill represents the excess of costs over fair value of assets of businesses acquired. Goodwill is tested for impairment at least annually or on an interim basis if an event triggering impairment may have occurred. As of October 1, 2021, after completing goodwill testing, we have determined that no goodwill impairment exists. Identified intangible assets are acquired assets that lack physical substance but can be distinguished from goodwill because of contractual or other legal rights or because the asset is capable of being sold or exchanged either on its own or in combination with a related contract, asset, or liability. Our identified intangible assets relate to core deposits and contract rights. As of December 31, 2021, we have determined that no impairment of identified intangibles exists. Identified intangible assets with definite useful lives are amortized on an accelerated basis over their estimated life. See Note 6— Goodwill and Other Intangible Assets. Impairment of Long-Lived Assets Long-lived assets, such as property, plant and equipment, and purchased intangibles subject to amortization, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying value of the asset to the estimated undiscounted future cash flows expected to be generated by the asset. If the carrying value of an asset exceeds its estimated future cash flows, an impairment charge is recognized by the amount by which the carrying value of the asset exceeds the fair value of the asset. Assets to be disposed of would be separately presented in the statement of condition and reported at the lower of the carrying value or fair value less costs to sell, and are no longer depreciated. The assets and liabilities of a disposed group classified as held for sale would be presented separately in the appropriate asset and liability sections of the statement of condition. Consolidated Statements of Cash Flows For purposes of the consolidated statements of cash flows, we consider all short-term investments with a maturity at date of purchase of three months or less to be cash equivalents. Also, we report transactions related to deposits and loans to customers on a net basis. Accounting for Transfers and Servicing of Financial Assets We account for transfers and servicing of financial assets and extinguishments of liabilities based on the application of a financial-components approach that focuses on control. After a transfer of financial assets, we recognize the financial and servicing assets we control and liabilities we have incurred, derecognize financial assets when control has been surrendered and derecognize liabilities when extinguished. We have retained mortgage servicing rights in connection with the sale of mortgage loans. Because we may not initially identify loans as originated for resale, all loans are initially treated as held for investment. The value of the mortgage servicing rights are reviewed periodically for impairment and are amortized in proportion to, and over the period of estimated net servicing income or net servicing losses. The value of the mortgage servicing rights is not significant to the consolidated statements of condition. Segments of an Enterprise and Related Information We operate as one segment. The operating information used by our chief executive officer for purposes of assessing performance and making operating decisions is the consolidated financial statements presented in this report. 42 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) We have five active operating subsidiaries, namely, the Subsidiary Banks. We apply the provisions of ASC Topic 280, “Segment Reporting,” in determining our reportable segments and related disclosures. Comprehensive Income (Loss) Comprehensive income (loss) consists of net income and other comprehensive income (loss). Other comprehensive income (loss) includes unrealized gains and losses on securities available for sale. Advertising Advertising costs are expensed as incurred. Reclassifications Certain amounts in the prior year’s presentations have been reclassified to conform to the current presentation. These reclassifications had no effect on previously reported net income or shareholders’ equity. New Accounting Standards In June 2016, the FASB issued Accounting Standards Update No. 2016-13 to ASC 326, “Financial Instruments – Credit Losses.” The update amends existing standards for accounting for credit losses for financial assets. The update requires that the expected credit losses on the financial instruments held as of the end of the period being reported be measured based on historical experience, current conditions, and reasonable and supportable forecasts. The update also expands the required disclosures related to significant estimates and judgements used in estimating credit losses, as well as the credit quality and underwriting standards of an organization’s financial assets. The update also amended the accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration. The impact of the adoption of the standard is to be recorded as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The accounting standard was effective for us on January 1, 2020. The task force formed last year, which includes key members of the teams that work with the calculation of the allowance for probable loan losses plus members representing the corporate accounting and risk management areas, has worked with the implementation of the update and validation to complete our model/tool. Based on the composition of the portfolio at December 31, 2019 and after finalizing the methodology, the adoption of the update increased our allowance for probable loan losses (referred to as the ACL under ASU 2016-13), by approximately 17.2%, resulting in a cumulative-effect adjustment to retained earnings of approximately $8.3 million, net of tax. Please refer to Note 4 – Allowance for Credit Losses and the Critical Accounting Policies discussion in Management’s Discussion and Analysis. In December 2019, the FASB issued Accounting Standards Update No. 2019-12, to ASC 740, “Income Taxes.” The update amends existing guidance with the intention of simplifying the accounting for income taxes. Specifically, the update removes some exceptions in existing guidance around intraperiod tax allocations, recognition of deferred tax liabilities for certain changes in investments in foreign subsidiaries and to the general methodology for calculating taxes on interim periods when year to date losses exceed the anticipated loss for the year. Additionally, the update clarifies and provides more guidance with respect to the classification of franchise or similar taxes, requirements to evaluate when a step up in the tax basis of goodwill should be considered, eliminates the requirement that a consolidated entity allocate a portion of current and deferred tax expense to a legal entity that is not subject to tax, requires that an entity reflect the effect of changes in tax laws and tax rates in the effective tax rate computed in the interim period that includes the enactment date and makes minor changes for taxes related to employee stock ownership plans and investments in qualified affordable housing projects accounted for using the equity method. The update is effective for fiscal years beginning after December 15, 2020. The adoption of the update did not have a significant impact on our consolidated financial statements. In March 2020, the FASB issued Accounting Standards Update No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting.” The update provides optional guidance for a limited period of time to ease the potential burden in accounting for and recognizing the effects of reference 43 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) rate reform on financial reporting. The practical expedients and exceptions in the update apply only to contracts, hedging relationships and other transactions affected by reference rate reform if certain criteria are met. The update does not apply to contract modifications made and hedging relationships entered into or evaluated after December 31, 2022, except for hedging relationships existing as of December 31, 2022 that an entity has elected certain optional expedients for and that are retained through the end of the hedging relationship. The update was effective as of the date of issuance and can be applied through December 31, 2022. We have not adopted the provisions of the update and do not anticipate that the adoption of the update will have a significant impact on our consolidated financial statements. In January 2021, the FASB issued Accounting Standards Update No. 2021-01, “Reference Rate Reform (Topic 848): Scope.” The update clarifies the applicability of the practical expedients and exceptions issued in ASU 2020-04 to derivative instruments that use an interest rate for margining, discounting or contract price alignment that is modified as a result of reference rate reform. The update is intended to capture the incremental consequences of the scope clarification and tailor the existing guidance to derivative instruments affected by the discounting transition. The update was effective as of the date of issuance and can be applied through December 31, 2022. We have not adopted the provisions of the update and do not anticipate that the adoption of the update will have a significant impact on our consolidated financial statements. (2) Investment Securities, Equity Securities with Readily Determinable Fair Values and Other Investments In accordance with ASU 2016-13, which we adopted on January 1, 2020, available-for-sale and held-to-maturity debt securities in an unrealized loss position must be evaluated for the underlying cause of the loss. In the event that the deterioration in value is attributable to credit related reasons, then the amount of credit-related impairment would be recorded as a charge to our ACL with subsequent changes in the amount of impairment, up or down, also recorded through our ACL. The exception to this process will occur if we intend to sell an impaired available-for-sale debt security or if we will more likely than not be required to sell a credit impaired available-for-sale debt security prior to the value recovering to the security’s amortized cost. In those situations, the entire credit-related impairment amount would be required to be recognized in earnings. We have evaluated the debt securities classified as available-for-sale and held-to-maturity at December 31, 2021 and have determined that no debt securities in an unrealized loss position are arising from credit related reasons and have therefore not recorded any allowances for debt securities in our ACL for the period. Unrealized gains and losses related to equity securities with readily determinable fair values are included in net income. The amortized cost and estimated fair value by type of investment security at December 31, 2021 are as follows: Held to Maturity Gross Gross Amortized unrealized unrealized cost gains losses Estimated fair value Carrying value (Dollars in Thousands) Other securities. . . . . . . . . . . . . . . . . . . . . . . . . . . $ Total investment securities . . . . . . . . . . . . . . . . . $ 3,400 $ 3,400 $ — $ — $ — $ — $ 3,400 $ 3,400 $ 3,400 3,400 Available for Sale Debt Securities Gross Gross Amortized unrealized unrealized cost gains losses (Dollars in Thousands) Estimated fair value Carrying value(1) Residential mortgage-backed securities . . . . . . . . . . $ 4,213,441 $ 14,159 $ (58,237) $ 4,169,363 $ 4,169,363 Obligations of states and political subdivisions . . . . 44,557 Total investment securities . . . . . . . . . . . . . . . . . . . . $ 4,254,960 $ 17,197 $ (58,237) $ 4,213,920 $ 4,213,920 44,557 41,519 3,038 — (1) Included in the carrying value of residential mortgage- backed securities are $824,474 of mortgage-backed securities issued by Ginnie Mae and $3,344,889 of mortgage-backed securities issued by Fannie Mae and Freddie Mac 44 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) The amortized cost and estimated fair value of investment securities at December 31, 2021, by contractual maturity, are shown below.

Investments in residential mortgage-backed securities issued by Ginnie Mae are fully guaranteed by the U.S. government. Investments in mortgage-backed securities issued by Freddie Mac and Fannie Mae are not fully guaranteed by the U.S. government; however, we believe that the quality of the bonds is similar to other AAA rated bonds with limited credit risk, particularly given the placement of Fannie Mae and Freddie Mac into conservatorship by the federal government in early September 2008 and because securities issued by others that are collateralized by residential mortgage-backed securities issued by Fannie Mae and Freddie Mac are rated consistently as AAA rated securities. The amortized cost and fair value of available for sale investment securities pledged to qualify for fiduciary powers, to secure public monies as required by law, repurchase agreements and short-term fixed borrowings was $1,519,652,000 and $1,497,929,000, respectively, at December 31, 2021. Proceeds from the sale and call of securities available-for-sale were $5,890,000, $42,350,000 and $94,585,000 during 2021, 2020 and 2019, respectively, which amounts included $0, $0 and $0 of mortgage-backed securities. Gross gains of $0, $1,000 and $3,000, and gross losses of $16,000, $6,000 and $15,000 were realized on the sales and calls in 2021, 2020 and 2019, respectively. 45 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position, at December 31, 2021 were as follows: Less than 12 months 12 months or more Total Fair Value Fair Value Losses Fair Value Unrealized Losses Unrealized Unrealized Losses Available for sale: Residential mortgage-backed securities . . . . . . . . . . . . . . . $ 3,037,188 $ (53,060) $ 423,733 $ $ 3,037,188 $ (53,060) $ 423,733 $ (5,177) $ 3,460,921 $ (58,237) (5,177) $ 3,460,921 $ (58,237) (Dollars in Thousands) Gross unrealized losses on investment securities and the fair value of the related securities, aggregated by investment category and length of time that individual securities have been in a continuous loss position, at December 31, 2020 were as follows: Less than 12 months 12 months or more Total Fair Value Fair Value Losses Fair Value Unrealized Losses Unrealized Unrealized Losses Available for sale: Residential mortgage-backed securities . . . . . . . . . . . . . . . $ 1,462,232 $ Obligations of states and political subdivisions . . . . . . . . . — (9,339) $ — $ 1,462,232 $ (9,339) $ — $ 757 757 $ — $ 1,462,232 $ (14) 757 (14) $ 1,462,989 $ (9,339) (14) (9,353) (Dollars in Thousands) The unrealized losses on investments in residential mortgage-backed securities are primarily caused by changes in market interest rates. We have no intent to sell and more likely than not be required to sell before a market price recovery or maturity of the securities; therefore, it is our conclusion that the investments in residential mortgage-backed securities issued by Freddie Mac, Fannie Mae and Ginnie Mae are not considered other-than-temporarily impaired. Equity securities with readily determinable fair values consist primarily of Community Reinvestment Act funds. At December 31, 2021 and December 31, 2020, the balance in equity securities with readily determinable fair values recorded at fair value were $6,079,000 and $6,202,000, respectively.

Results and information regarding our ACL included in this Note are calculated and presented in accordance with that accounting standards update. Results and information prior to January 1, 2020 are calculated and presented in accordance with previously applicable U.S. GAAP. ASU 2016-13 replaces the long-standing incurred loss model with an expected credit loss model that recognizes credit losses over the life of a financial asset. Expected credit losses capture historical information, current conditions, and reasonable and supportable forecasts of future conditions. The ACL is deducted from the amortized cost of an instrument to present the net amount expected to be collected on the financial asset. Our ACL primarily consists of the aggregate ACL estimates of our Subsidiary Banks. The estimates are established through charges to operations in the form of charges to provisions for credit loss expense. Loan losses or recoveries are charged or credited directly to the 47 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) ACL. The ACL of each Subsidiary Bank is maintained at a level considered appropriate by management, based on estimated current expected credit losses in the current loan portfolio, including information about past events, current conditions and reasonable and supportable forecasts. The estimation of the ACL is based on a loss-rate methodology that measures lifetime losses on loan pools that have similar risk characteristics. Loans that do not have similar risk characteristics are evaluated on an individual basis. The segmentation of the loan portfolio into pools requires a balancing process between capturing similar risk characteristics and containing sufficient loss history to provide meaningful results. Our segmentation starts at the general loan category with further sub-segmentation based on collateral types that may be of meaningful size and/or may contain sufficient differences in risk characteristics based on management’s judgement that would warrant further segmentation. The general loan categories along with primary risk characteristics used in our calculation are as follows: Commercial and industrial loans. This category includes loans extended to a diverse array of businesses for working capital or equipment purchases. These loans are mostly secured by the collateral pledged by the borrower that is directly related to the business activities of the company such as equipment, accounts receivable and inventory. The borrower’s abilities to generate revenues from equipment purchases, collect accounts receivable, and to turn inventory into sales are risk factors in the repayment of the loan. A small portion of this loan category is related to loans secured by oil & gas production and loans secured by aircraft. Construction and land development loans. This category includes the development of land from unimproved land to lot development for both residential and commercial use and vertical construction across residential and commercial real estate classes. These loans carry risk of repayment when projects incur cost overruns, have an increase in the price of construction materials, encounter zoning, entitlement and environmental issues, or encounter other factors that may affect the completion of a project on time and on budget. Additionally, repayment risk may be negatively impacted when the market experiences a deterioration in the value of real estate. Risks specifically related to 1-4 family development loans also include mortgage rate risk and the practice by the mortgage industry of more restrictive underwriting standards, which inhibits the buyer from obtaining long term financing creating excessive housing and lot inventory in the market. Commercial real estate loans. This category includes loans secured by farmland, multifamily properties, owner occupied commercial properties, and non-owner occupied commercial properties. Owner occupied commercial properties include warehouses often along the border for import/export operations, office space where the borrower is the primary tenant, restaurants and other single-tenant retail. Non-owner occupied commercial properties include hotels, retail centers, office and professional buildings, and leased warehouses. These loans carry risk of repayment when market values deteriorate, the business experiences turnover in key management, the business has an inability to attract or keep occupancy levels stable, or when the market experiences an exit of a specific business type that is significant to the local economy, such as a manufacturing plant. 1-4 family mortgages. This category includes both first and second lien mortgages for the purpose of home purchases or refinancing of existing mortgage loans. A small portion of this loan category is related to home equity lines of credits, lots purchases, and home construction. Loan repayments may be affected by unemployment or underemployment and deteriorating market values of real estate. Consumer loans. This category includes deposit secured, vehicle secured, and unsecured loans, including overdrafts, made to individuals. Repayment is primarily affected by unemployment or underemployment. The loan pools are further broken down using a risk-based segmentation based on internal classifications for commercial loans and past due status for consumer mortgage loans. Non-mortgage consumer loans are evaluated as one segment. On a weekly basis, commercial loan past due reports are reviewed by the credit quality committee to determine if a loan has any potential problems and if a loan should be placed on our internal Watch List report. Additionally, our credit department reviews the majority of our loans for proper internal classification purposes regardless of whether they are past due and segregates any loans with potential problems for further review. The credit department will discuss the potential problem loans with the servicing loan officers to determine any relevant issues that were not discovered in the evaluation. Also, an analysis of loans that is provided through examinations by regulatory authorities is considered in the 48 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) review process. After the above analysis is completed, we will determine if a loan should be placed on an internal Watch List report because of issues related to the analysis of the credit, credit documents, collateral and/or payment history. Our internal Watch List report is segregated into the following categories: (i) Pass, (ii) Economic Monitoring, (iii) Special Review, (iv) Watch List—Pass, or (v) Watch List—Substandard, and (vi) Watch List—Doubtful. The loans placed in the Special Review category and lower rated credits reflect our opinion that the loans reflect potential weakness which require monitoring on a more frequent basis. Credits in those categories are reviewed and discussed on a regular basis, no less frequently than quarterly, with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the Watch List—Pass category and lower rated credits reflect our opinion that the credit contains weaknesses which represent a greater degree of risk, which warrant “extra attention.” Credits in this category are reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the Watch List—Substandard category are considered to be potentially inadequately protected by the current sound worth and debt service capacity of the borrower or of any pledged collateral. These credit obligations, even if apparently protected by collateral value, have shown defined weaknesses related to adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and interest. Furthermore, there is the possibility that we may sustain some future loss if such weaknesses are not corrected. The loans placed in the Watch List—Doubtful category have shown defined weaknesses and it is likely, based on current information and events, that we will be unable to collect all principal and/or interest amounts contractually due. Watch List—Doubtful loans are placed on non-accrual when they are moved to that category. For the purposes of the ACL, in order to maintain segments with sufficient history for meaningful results, the credits in the Pass and Economic Monitoring categories are aggregated, the credits in the Special Review and Watch List— Pass credits are aggregated, and the credits in the Watch List—Substandard category remain in their own segment. For loans that are classified as Watch List—Doubtful, management evaluates these credits in accordance with ASC 310-10, “Receivables,” and, if deemed necessary, a specific reserve is allocated to the loan. The specific reserve allocated under ASC 310-10, is based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the loan’s observable market price; or (iii) net realizable value of the fair value of the collateral if the loan is collateral dependent. Substantially all of our loans evaluated as Watch List—Doubtful under ASC 310-10 are measured using the fair value of collateral method. In rare cases, we may use other methods to determine the specific reserve of a loan under ASC 310-10 if such loan is not collateral dependent. Within each collectively evaluated pool, the robustness of the lifetime historical loss-rate is evaluated and, if needed, is supplemented with peer loss rates through a model risk adjustment. Certain qualitative loss factors are then evaluated to incorporate management’s two-year reasonable and supportable forecast period followed by a reversion to the pool’s average lifetime loss-rate. Those qualitative loss factors are: (i) trends in portfolio volume and composition, (ii) volume and trends in classified loans, delinquencies, non-accruals and TDR’s, (iii) concentration risk, (iv) trends in underlying collateral value, (v) changes in policies, procedures, and strategies, and (vi) economic conditions. Qualitative factors also include potential losses stemming from operational risk factors arising from fraud, natural disasters, pandemics and geopolitical events. Should any of the factors considered by management in evaluating the adequacy of the ACL change, our estimate could also change, which could affect the level of future credit loss expense. We have elected to not measure an ACL for accrued interest receivable given our timely approach in identifying and writing off uncollectible accrued interest. An ACL for off-balance sheet exposure is derived from a projected usage rate of any unfunded commitment multiplied by the historical loss rate, plus model risk adjustment, if any, of the on- balance sheet loan pools. Our management continually reviews the ACL of the Subsidiary Banks using the amounts determined from the estimates established on specific doubtful loans, the estimate established on quantitative historical loss percentages, and the estimate based on qualitative current conditions and reasonable and supportable two-year forecasted data. Our methodology reverts to the average lifetime loss-rate beyond the forecast period when we can no longer develop reasonable and supportable forecasts. Should any of the factors considered by management in evaluating the adequacy of the estimate for current expected credit losses change, our estimate of current expected credit losses could also change, which could affect the level of future credit loss expense. While the calculation of our ACL utilizes management’s best judgment and all information reasonably available, the adequacy of the ACL is dependent on a variety of factors beyond our control, 49 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) including, among other things, the performance of the entire loan portfolio, the economy, government actions, changes in interest rates and the view of regulatory authorities towards loan classifications.

The credit loss expense charged to operations for the twelve months ended December 31, 2021 has decreased from the same period of 2020 as economic conditions in 2021 stabilized and in some cases, improved, impacting certain segments of our loan portfolio. The stabilization and improvement means that the pool specific qualitative loss factors used in the December 31, 2020 ACL calculation have remained constant in the December 31, 2021 ACL calculation, which 50 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) positively impacted the calculation and resulted in a decrease in the credit loss expense for 2021. The credit loss expense charged to operations increased for the year ended December 31, 2020 and can be primarily attributed to the deteriorating economic conditions occurring in those periods as a result of COVID-19 and the impact of those conditions on certain segments of our ACL calculation for those periods. We adopted the provisions of ASU 2016-13 on January 1, 2020, resulting in a transition from the long-standing incurred loss model to an expected credit loss model. The increase in provision for probable loan losses charged to expense and charge-offs charged to the allowance for probable loan losses for the year ended December 31, 2019 can be primarily attributed to a relationship that is secured by multiple pieces of real property on which car dealerships are operated. The relationship began deteriorating in the fourth quarter of 2018, triggered by significant fraud by a high level insider of the car dealership resulting in the dealerships unexpectedly filing for bankruptcy and creating an exposure for potential loss since the operations of the dealerships were the source of repayment from the borrower. The relationship further deteriorated in the first quarter of 2019 after the sponsor of the court approved debtor in possession plan discontinued its role in the process and thus did not fulfill its obligation to assume full responsibility of the accrued and unpaid interest. Although the relationship is secured by real property (the dealerships’ real estate), the real property has specialized use, contributing to the potential exposure for probable loss. During the first quarter of 2019, in light of the circumstances and management’s evaluation of the relationship, the decision was made to place the relationship on impaired, non-accrual status and place a specific reserve on the relationship in the amount of $9.5 million. During the second quarter of 2019, management continued to evaluate the relationship and decided to foreclose on the underlying real estate collateral, resulting in a charge-off of approximately $9.5 million, reflected in the tables above as part of the Commercial and commercial real estate: farmland and commercial categories.

The decrease in non-accrual Commercial loans at December 31, 2021 compared to December 31, 2020 can be attributed to a relationship secured by commercial property that was placed on non-accrual in the fourth quarter of 2020 and foreclosed upon in the first quarter of 2021. The effect of such non-accrual loans reduced interest income by approximately $169,000, $694,000 and $340,000 for the years ended December 31, 2021, 2020 and 2019, respectively. Amounts received on non-accruals are applied, for financial accounting purposes, first to principal and then to interest after all principal has been collected. Accruing loans contractually past due 90 days or more as to principal or interest payments at December 31, 2021, 2020 and 2019 amounted to approximately $8,642,000, $8,238,000 and $59,705,000, respectively.

We have identified these loans through our normal loan review procedures. Doubtful loans are measured based on (i) the present value of expected future cash flows discounted at the loan’s effective interest rate; (ii) the loan’s observable market price; or (iii) the fair value of the collateral if the loan is collateral dependent. Substantially all of our doubtful loans are measured at the fair value of the collateral. In limited cases, we may use other methods to determine the level of impairment of a loan if such loan is not collateral dependent.

We have been offering and are prepared to continue to offer assistance in accordance with current regulatory guidance. That includes continuously reaching out to our customers and, in some cases, offering short-term payment deferral plans. In accordance with the Coronavirus Aid, Relief and Economic Security (“CARES”) Act or interagency regulatory guidance, these short-term deferrals are not considered troubled debt restructurings. As of February 18, 2022, approximately $123,194,000 in loans with some degree of payment deferrals were in our system. In accordance with interagency regulatory guidance these short-term deferrals are not considered troubled debt restructurings. The $123,194,000 is comprised primarily of loans related to industries that have been significantly impacted by the COVID-19 pandemic, including the hospitality sector, special use facilities, including child-care centers, and retail developments. With the passage of the Paycheck Protection Program (“PPP”), administered by the Small Business Association (“SBA”), we assisted our customers with applications for loans through the PPP. PPP loans earn interest at 1% and PPP loans made prior to June 5, 2020 have a two-year term, while those made after June 5, 2020 have a five-year term; however, PPP loans also include forgiveness provisions that we expect most customers will utilize. Customers began submitting applications for the forgiveness program in the third quarter of 2020. PPP loans were intended to support up to 24 weeks of payroll and certain other costs to help those businesses remain viable and allow their employees to pay their bills. As of February 18, 2022, we had 968 PPP loans totaling approximately $71,149,000 outstanding. The PPP loans are fully guaranteed by the U.S. government through the SBA. The Subsidiary Banks charge-off that portion of any loan which management considers to represent a loss as well as that portion of any other loan which is classified as a “loss” by bank examiners. Commercial and industrial or real estate loans are generally considered by management to represent a loss, in whole or part, when an exposure beyond any collateral coverage is apparent and when no further collection of the loss portion is anticipated based on the borrower’s financial condition and general economic conditions in the borrower’s industry. Generally, unsecured consumer loans are charged-off when 90 days past due. While management considers that it is generally able to identify borrowers with financial problems reasonably early and to monitor credit extended to such borrowers carefully, there is no precise method of predicting loan losses. The determination that a loan is likely to be uncollectible and that it should be wholly or partially charged-off as a loss is an exercise of judgment. Similarly, the determination of the adequacy of the ACL (formerly allowance for probable loan losses) can be made only on a subjective basis. It is the judgment of our management that the ACL at December 31, 2021 and December 31, 2020, was adequate to absorb expected losses from loans in the portfolio at that date. 53 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) The following table presents information regarding the aging of past due loans by loan class: December 31, 2021 30 - 59 Days Total 90 Days or Past 90 Days or greater & 60 - 89 Days Greater still accruing Due (Dollars in Thousands) Current Portfolio Total Domestic Commercial . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 2,534 $ Commercial real estate: other construction & 303 $ 577 $ 577 $ 3,414 $ 1,498,438 $ 1,501,852 land development . . . . . . . . . . . . . . . . . . . . . 499 334 188 188 1,021 1,667,092 1,668,113 Commercial real estate: farmland & commercial . . . . . . . . . . . . . . . . . . . . . . . . .

The decrease in commercial real estate: other construction & land development loans past due 90 days or greater at December 31, 2021 compared to December 31, 2020 can be primarily attributed to a relationship secured by commercial property which was foreclosed upon in the first quarter of 2021. Our internal classified report is segregated into the following categories: (i) “Special Review Credits,” (ii) “Watch List—Pass Credits,” or (iii) “Watch List—Substandard Credits.” The loans placed in the “Special Review Credits” category reflect our opinion that the loans reflect potential weakness which require monitoring on a more frequent basis. The “Special Review Credits” are reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the “Watch List—Pass Credits” category reflect our opinion that the credit contains weaknesses which represent a greater degree of risk, which warrant “extra attention.” The “Watch List—Pass Credits” are reviewed and discussed on a regular basis with the credit department and the lending staff to determine if a change in category is warranted. The loans placed in the “Watch List—Substandard Credits” classification are considered to be potentially inadequately protected by the current sound worth and debt service capacity of the borrower or of any pledged collateral. These credit obligations, even if apparently protected by collateral value, have shown defined weaknesses related to adverse financial, managerial, economic, market or political conditions which may jeopardize repayment of principal and interest. Furthermore, there is the possibility that we could sustain some future loss if such weaknesses are not corrected.

The decrease in Commercial Real Estate: Farmland and Commercial Watch-List Doubtful loans at December 31, 2021 compared to December 31, 2020 can be attributed to a relationship secured by commercial property that was foreclosed upon in the first quarter of 2021. 56 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (5) Bank Premises and Equipment A summary of bank premises and equipment, by asset classification, at December 31, 2021 and 2020 were as follows: Bank buildings and improvements . . . . . . . . . . . . . . . . . . . . .

(9) Other Borrowed Funds Other borrowed funds include Federal Home Loan Bank borrowings, which may be short and long-term fixed borrowings issued by the Federal Home Loan Bank of Dallas and the Federal Home Loan Bank of Topeka at the market price offered at the time of funding. These borrowings are secured by mortgage-backed investment securities and a portion of our loan portfolio. Further information regarding our other borrowed funds at December 31, 2021 and 2020 is set forth in the following table: December 31, 2021 2020 (Dollars in Thousands) Federal Home Loan Bank advances—short-term Balance at year end . . . . . . . . . . . . . . . . . . . . . . . . . . $ Rate on balance outstanding at year end . . . . . . . . .

The non- amortizing advances mature in the following increments: $75,000,000 in July 2028, $100,000,000 in March 2033 and $250,000,000 in August 2033 and are callable by the FHLB on a quarterly basis. Two amortizing advances are outstanding at December 31, 2021 in the amounts of $3,033,000 and $8,104,000 and mature in December 2033 and November 2033, respectively. The amortization on the amortizing long-term advances totals approximately $194,000, $199,000, $204,000, $210,000 and $2215,000 for the years ending December 31, 2022, 2023, 2024, 2025 and December 31, 2026, respectively. 60 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (10) Junior Subordinated Deferrable Interest Debentures We have formed five statutory business trusts under the laws of the State of Delaware for the purpose of issuing trust preferred securities. These statutory business trusts (the “Trusts”) have each issued Capital and Common Securities and invested the proceeds thereof in an equivalent amount of junior subordinated debentures (the “Debentures”) we issued. As of December 31, 2021 and December 31, 2020, the principal amount of debentures outstanding totaled $134,642,000. The Debentures are subordinated and junior in right of payment to all our present and future senior indebtedness (as defined in the respective indentures) and are pari passu with one another. The interest rate payable on, and the payment terms of the Debentures are the same as the distribution rate and payment terms of the respective issues of Capital and Common Securities issued by the Trusts. We have fully and unconditionally guaranteed the obligations of each of the Trusts with respect to the Capital and Common Securities. We have the right, unless an Event of Default (as defined in the Indentures) has occurred and is continuing, to defer payment of interest on the Debentures for up to twenty consecutive quarterly periods on Trusts VIII, IX, X, XI and XII. If interest payments on any of the Debentures are deferred, distributions on both the Capital and Common Securities related to that Debenture would also be deferred. The redemption prior to maturity of any of the Debentures may require the prior approval of the Federal Reserve and/or other regulatory bodies. For financial reporting purposes, the Trusts are treated as investments and not consolidated in the consolidated financial statements. Although the Capital Securities issued by each of the Trusts are not included as a component of shareholders’ equity on the consolidated statement of condition, the Capital Securities are treated as capital for regulatory purposes. Specifically, under applicable regulatory guidelines, the Capital Securities issued by the Trusts qualify as Tier 1 capital up to a maximum of 25% of Tier 1 capital on an aggregate basis. Any amount that exceeds the 25% threshold would qualify as Tier 2 capital. At December 31, 2021 and December 31, 2020, the total $134,642,000 of the Capital Securities outstanding qualified as Tier 1 capital.

(11) Earnings per Share (“EPS”) Basic EPS is calculated by dividing net income by the weighted average number of common shares outstanding. The computation of diluted EPS assumes the issuance of common shares for all dilutive potential common shares 61 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) outstanding during the reporting period.

Our annual contribution to the plan is based on a percentage, as determined by our Board of Directors, of income before income taxes, as defined, for the year. Allocation of the contribution among officers and employees’ accounts is based on length of service and amount of salary earned. Profit sharing costs of $3,550,000, $4,000,000 and $4,200,000 were charged to income for the years ended December 31, 2021, 2020, and 2019, respectively. (13) International Operations We provide international banking services for our customers through our Subsidiary Banks. Neither we nor our Subsidiary Banks have facilities located outside the United States. International operations are distinguished from domestic operations based upon the domicile of the customer. Because the resources we employ are common to both international and domestic operations, it is not practical to determine net income generated exclusively from international activities. 62 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) A summary of assets attributable to international operations at December 31, 2021 and 2020 are as follows: Loans: Commercial . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ Others . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Revenues directly attributable to international operations were approximately $4,090,000, $4,676,000 and $5,445,000 for the years ended December 31, 2021, 2020 and 2019, respectively.

(15) Stock Options On April 5, 2012, the Board of Directors adopted the 2012 International Bancshares Corporation Stock Option Plan (the “2012 Plan”). There are 800,000 shares available for stock option grants under the 2012 Plan. Under the 2012 Plan, both qualified incentive stock options (“ISOs”) and non-qualified stock options (“NQSOs”) may be granted. Options granted may be exercisable for a period of up to 10 years from the date of grant, excluding ISOs granted to 10% shareholders, which may be exercisable for a period of up to only five years. As of December 31, 2021, 30,678 shares were available for future grants under the 2012 Plan. 64 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) The fair value of each option award granted under the plan is estimated on the date of grant using a Black-Scholes-Merton option valuation model that uses the assumptions noted in the following table. Expected volatility is based on the historical volatility of the price of our stock. We use historical data to estimate the expected dividend yield and employee termination rates within the valuation model. The expected term of options is derived from historical exercise behavior. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

We are involved in various legal proceedings that are in various stages of litigation. We have determined, based on discussions with our counsel that any material loss in such actions, individually or in the aggregate, is remote or the damages sought, even if fully recovered, would not be considered material to our consolidated statements of condition and related statements of income, comprehensive income, shareholders’ equity and cash flows. However, many of these matters are in various stages of proceedings and further developments could cause management to revise its assessment of these matters. (17) Transactions with Related Parties In the ordinary course of business, the Subsidiary Banks make loans to our directors and executive officers, including their affiliates, families and companies in which they are principal owners. In the opinion of management, these loans are made on substantially the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with other persons and do not involve more than normal risk of collectability or present other unfavorable features. The aggregate amounts receivable from such related parties amounted to approximately $18,881,000 and $30,398,000 at December 31, 2021 and 2020, respectively. (18) Financial Instruments with Off-Statement of Condition Risk and Concentrations of Credit Risk In the normal course of business, the Subsidiary Banks are party to financial instruments with off-statement of condition risk to meet the financing needs of their customers. These financial instruments include commitments to their customers. These financial instruments involve, to varying degrees, elements of credit risk in excess of the amounts recognized in the consolidated statement of condition. The contract amounts of these instruments reflect the extent of involvement the Subsidiary Banks have in particular classes of financial instruments. At December 31, 2021, the following financial amounts of instruments, whose contract amounts represent credit risks, were outstanding: Commitments to extend credit . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ Credit card lines . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

These guarantees are primarily issued to support public and private borrowing arrangements. The credit risk involved is represented by the contractual amounts of those instruments. Under the standby letters of credit, we are required to make payments to the beneficiary of the letters of credit upon request by the beneficiary so long as all performance criteria have been met. At December 31, 2021, the maximum potential amount of future payments is approximately $111,955,000. At December 31, 2021, the fair value of these guarantees is not significant. Unsecured letters of credit totaled approximately $29,254,000 and $39,487,000 at December 31, 2021 and 2020, respectively. We enter into commercial letters of credit on behalf of our customers which authorize a third party to draw drafts upon us up to a stipulated amount and with specific terms and conditions. A commercial letter of credit is a conditional commitment on our part to provide payment on drafts drawn in accordance with the terms of the commercial letter of credit. The Subsidiary Banks’ exposure to credit loss in the event of nonperformance by the other party to the above financial instruments is represented by the contractual amounts of the instruments. The Subsidiary Banks use the same credit policies in making commitments and conditional obligations as they do for on-statement of condition instruments. The Subsidiary Banks control the credit risk of these transactions through credit approvals, limits and monitoring procedures. Commitments to extend credit are agreements to lend to a customer as long as there is no violation of any 66 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) condition established in the contract. Commitments generally have fixed expiration dates normally less than one year or other termination clauses and may require the payment of a fee. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. The Subsidiary Banks evaluate each customer’s credit-worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by the Subsidiary Banks upon extension of credit, is based on management’s credit evaluation of the customer. Collateral held varies, but may include residential and commercial real estate, bank certificates of deposit, accounts receivable and inventory. The Subsidiary Banks make commercial, real estate and consumer loans to customers principally located in South, Central and Southeast Texas and the State of Oklahoma. Although the loan portfolio is diversified, a substantial portion of its debtors’ ability to honor their contracts is dependent upon the economic conditions in these areas, especially in the real estate and commercial business sectors. (19) Capital Requirements Bank regulatory agencies limit the amount of dividends, which the Subsidiary Banks can pay, without obtaining prior approval from such agencies. At December 31, 2021, the Subsidiary Banks could pay dividends of up to $1,066,000,000 without prior regulatory approval and without adversely affecting their “well-capitalized” status under regulatory capital rules in effect at December 31, 2021. In addition to legal requirements, regulatory authorities also consider the adequacy of the Subsidiary Banks’ total capital in relation to their deposits and other factors. These capital adequacy considerations also limit amounts available for payment of dividends. We historically have not allowed any Subsidiary Bank to pay dividends in such a manner as to impair its capital adequacy. We and the Subsidiary Banks are subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on our consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, we must meet specific capital guidelines that involve quantitative measures of our assets, liabilities, and certain off-statement of condition items as calculated under regulatory accounting practices. Our capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. Current quantitative measures established by regulation to ensure capital adequacy require us to maintain minimum amounts and ratios (set forth in the table on the following page) of Total and Tier 1 capital to risk-weighted assets and of Tier 1 capital to average assets. Management believes, as of December 31, 2021, that we met all capital adequacy requirements to which we are subject. In July 2013, the FDIC and other regulatory bodies established a new, comprehensive capital framework for U.S. banking organizations, consisting of minimum requirements that increase both the quantity and quality of capital held by banking organizations. The final rules are a result of the implementation of the BASEL III capital reforms and various Dodd-Frank related capital provisions. Consistent with the Basel international framework, the rules include a new minimum ratio of Common Equity Tier 1 (“CET1”) to risk-weighted assets of 4.5% and a CET1 capital conservation buffer of 2.5% of risk-weighted assets. The capital conservation buffer began phasing-in on January 1, 2016 at .625% and increased each year until January 1, 2019, when we were required to have a 2.5% capital conservation buffer, effectively resulting in a minimum ratio of CET1 capital to risk-weighted assets of at least 7% upon full implementation. The rules also raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4% to 6% and include a minimum leverage ratio of 4% for all banking organizations. Regarding the quality of capital, the rules emphasize CET1 capital and implements strict eligibility criteria for regulatory capital instruments. The rules also improve the methodology for calculating risk-weighted assets to enhance risk sensitivity. The rules were subject to a four-year phase-in period for mandatory compliance and we were required to begin to phase-in the new rules beginning on January 1, 2015. We believe that as of December 31, 2021, we meet all fully phased-in capital adequacy requirements. On November 21, 2017, the OCC, the Federal Reserve and the FDIC finalized a proposed rule that extends the current treatment under the regulatory capital rules for certain regulatory capital deductions and risk weights and certain minority interest requirements, as they apply to banking organizations that are not subject to the advanced approaches 67 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) capital rules. Effective January 1, 2018, the rule also paused the full transition to the Basel III treatment of mortgage servicing assets, certain deferred tax assets, investments in the capital of unconsolidated financial institutions and minority interests. The agencies are also considering whether to make adjustments to the capital rules in response to CECL (the FASB Standard relating to current expected credit loss) and its potential impact on regulatory capital. On December 7, 2017, the Basel Committee on Banking Supervision unveiled the latest round of its regulatory capital framework, commonly called “Basel IV.” The framework makes changes to the capital framework first introduced as “Basel III” in 2010. The committee targeted 2022-2027 as the timeframe for implementation by regulators in individual countries, including the U.S. federal bank regulatory agencies (after notice and comment). The aforementioned capital conservation buffer is designed to absorb losses during periods of economic stress. Banking institutions with a ratio of CET1 capital to risk-weighted assets above the minimum but below the conservation buffer will face constraints on dividends, equity repurchases and compensation based on the amount of the shortfall. As of December 31, 2021, our capital levels continue to exceed all capital adequacy requirements under the Basel III Capital Rules as currently applicable to us. On May 24, 2018, the EGRRCPA was enacted and, among other things, it includes a simplified capital rule change which effectively exempts banks with assets of less than $10 billion that exceed the “community bank leverage ratio,” from all risk-based capital requirements, including Basel III and its predecessors. The federal banking agencies must establish the “community bank leverage ratio” (a ratio of tangible equity to average consolidated assets) between 8% and 10% before community banks can begin to take advantage of this regulatory relief provision. Some of the Subsidiary Banks, with assets of less than $10 billion, may qualify for this exemption. Additionally, under the EGRRCPA, qualified bank holding companies with assets of up to $3 billion (currently $1 billion) will be eligible for the Federal Reserve’s Small Bank Holding Company Policy Statement, which eases limitations on the issuance of debt by holding companies. On August 28, 2018, the Federal Reserve issued an interim final rule expanding the applicability of its Small Bank Holding Company Policy Statement. While holding companies that meet the conditions of the policy statement are excluded from consolidated capital requirements, their depository institutions continue to be subject to minimum capital requirements. Finally, for banks that continue to be subject to the risk-based capital rules of Basel III (e.g., 150%), certain commercial real estate loans that were formally classified as high volatility commercial real estate 31 (“HVCRE”) will not be subject to heightened risk weights if they meet certain criteria. Also, while acquisition, development, and construction (“ADC”) loans will generally be subject to heightened risk weights, certain exceptions will apply. On September 18, 2018, the federal banking agencies issued a proposed rule modifying the agencies’ capital rules for HVCRE. As of December 31, 2021, the most recent notification from the FDIC categorized all the Subsidiary Banks as well-capitalized under the regulatory framework for prompt corrective action. To be categorized as “well-capitalized,” we must maintain minimum Total risk-based, Tier 1 risk based, and Tier 1 leverage ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed our categorization as well-capitalized. In December 2018, the federal bank regulators issued a final rule that would provide an optional three-year phase- in period for the day-one regulatory capital effects of the adoption of ASU 2016-13 to ASC 326 “Financial Instruments – Credit Losses,” as amended, on January 1, 2020. We did not elect to use the optional three-year phase-in period when we adopted ASU 2016-13 to ASC 326 “Financial Instruments – Credit Losses,” as amended, on January 1, 2020. 68 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Our actual capital amounts and ratios for 2021 under current guidelines are presented in the following table: Actual For Capital Adequacy Purposes Phase In Schedule To Be Well-Capitalized Under Prompt Corrective Action Provisions Amount Ratio Amount Ratio Amount Ratio (greater than (greater than (greater than (greater than or equal to) or equal to) or equal to) or equal to) (Dollars in Thousands) As of December 31, 2021: Common Equity Tier 1 (to Risk Weighted Assets): Consolidated . . . . . . . . . . . . . . . . . . . . . . . . . . . . . $ 2,057,928 20.47 % $ International Bank of Commerce, Laredo . . . . . . . .

ASC 820 applies to all financial instruments that are being measured and reported on a fair value basis. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date; it also establishes a fair value hierarchy that prioritizes the inputs used in valuation methodologies into the following three levels: • Level 1 Inputs—Unadjusted quoted prices in active markets for identical assets or liabilities. • Level 2 Inputs—Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. • Level 3 Inputs—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or other valuation techniques, 70 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) as well as instruments for which the determination of fair value requires significant management judgment or estimation. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy is set forth below. The following table represents financial instruments reported on the consolidated statements of condition at their fair value as of December 31, 2021 by level within the fair value measurement hierarchy.

Equity securities with readily determinable fair values are classified within Level 1. For debt securities classified as Level 2 in the fair value hierarchy, we obtain fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. 71 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) Certain financial instruments are measured at fair value on a nonrecurring basis. They are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). The following table represents financial instruments measured at fair value on a non-recurring basis as of and for the period ended December 31, 2021 by level within the fair value measurement hierarchy: Fair Value Measurements at Reporting Date Using (in thousands) Quoted Assets/Liabilities Prices in Active Measured at Markets for Fair Value Identical Assets (Level 1) Period ended December 31, 2021 Significant Other Significant Observable Unobservable Inputs (Level 2) Inputs (Level 3) Net Provision (Credit) During Period Measured on a non-recurring basis: Assets: Watch-List doubtful loans . . . . . . . . . . . . . . . . . . . . $ Other real estate owned . . . . . . . . . . . . . . . . . . . . . . $ 55 $ 18,095 $ — $ — $ — $ 55 $ — $ 18,095 $ 209 2,655 The following table represents financial instruments measured at fair value on a non-recurring basis as of and for the year ended December 31, 2020 by level within the fair value measurement hierarchy: Fair Value Measurements at Reporting Date Using (in thousands) Quoted Assets/Liabilities Prices in Active Measured at Markets Fair Value Net (Credit) for Identical Observable Unobservable Provision Year ended Significant Other Significant Measured on a non-recurring basis: Assets: Watch-List doubtful loans . . . . . . . . . . . . . . . . . . . . . $ Other real estate owned . . . . . . . . . . . . . . . . . . . . . . . 393 $ 6,241 — $ — — $ — 393 $ 6,241 (86) 1,539 December 31, 2020 Assets (Level 1) Inputs (Level 2) Inputs (Level 3) During Period Our assets measured at fair value on a non-recurring basis are limited to loans classified as Watch List – Doubtful and other real estate owned. The fair value of Watch-List Doubtful loans is derived in accordance with FASB ASC 310, “Receivables”. They are primarily comprised of collateral-dependent commercial loans. As the primary sources of loan repayments decline, the secondary repayment source, the collateral, takes on greater significance. Correctly evaluating the fair value becomes even more important. Re-measurement of the loan to fair value is done through a specific valuation allowance included in the ACL. The fair value of the loan is based on the fair value of the collateral, as determined through either an appraisal or evaluation process. The basis for our appraisal and appraisal review process is based on regulatory guidelines and strives to comply with all regulatory appraisal laws, regulations, and the Uniform Standards of Professional Appraisal Practice. All appraisals and evaluations are “as is” (the property’s highest and best use) valuations based on the current conditions of the property/project at that point in time. The determination of the fair value of the collateral is based on the net realizable value, which is the appraised value less any closing costs, when applicable. As of December 31, 2021, we had approximately $993,000 of doubtful commercial collateral dependent loans, of which approximately $0 had an appraisal performed within the immediately preceding twelve months and of which approximately $896,000 had an evaluation performed within the immediately preceding twelve months. As of December 31, 2020, we had approximately $18,361,000 of doubtful commercial collateral dependent loans, of which approximately $16,587,000 had an appraisal 72 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) performed within the immediately preceding twelve months and of which approximately $1,283,000 had an evaluation performed within the immediately preceding twelve months. The determination to either seek an appraisal or to perform an evaluation begins in weekly credit quality meetings, where the committee analyzes the existing collateral values of the doubtful loans and where obsolete appraisals are identified. In order to determine whether we would obtain a new appraisal or perform an internal evaluation to determine the fair value of the collateral, the credit committee reviews the existing appraisal to determine if the collateral value is reasonable in view of the current use of the collateral and the economic environment related to the collateral. If the analysis of the existing appraisal does not find that the collateral value is reasonable under the current circumstances, we would obtain a new appraisal on the collateral or perform an internal evaluation of the collateral. The ultimate decision to get a new appraisal rests with the independent credit administration group. A new appraisal is not required if an internal evaluation, as performed by in-house experts, is able to appropriately update the original appraisal assumptions to reflect current market conditions and provide an estimate of the collateral’s market value for impairment analysis. The internal evaluations must be in writing and contain sufficient information detailing the analysis, assumptions and conclusions and they must support performing an evaluation in lieu of ordering a new appraisal. Other real estate owned is comprised of real estate acquired by foreclosure and deeds in lieu of foreclosure. Other real estate owned is carried at the lower of the recorded investment in the property or its fair value less estimated costs to sell such property (as determined by independent appraisal) within Level 3 of the fair value hierarchy. Prior to foreclosure, the value of the underlying loan is written down to the fair value of the real estate to be acquired by a charge to the ACL (formerly allowance for probable loan losses), if necessary. The fair value is reviewed periodically and subsequent write downs are made accordingly through a charge to operations. Other real estate owned is included in other assets on the consolidated financial statements. For the twelve months ended December 31, 2021, 2020 and 2019, we recorded approximately $2,000, $22,000 and $9,611,000, respectively, in charges to the ACL in connection with loans transferred to other real estate owned. For the twelve months ended December 31, 2021, 2020 and 2019, we recorded approximately $2,655,000, $1,539,000 and $322,000, respectively, in adjustments to fair value in connection with other real estate owned. The fair value estimates, methods, and assumptions for our financial instruments at December 31, 2021 and December 31, 2020 are outlined below. Cash and Cash Equivalents For these short-term instruments, the carrying amount is a reasonable estimate of fair value. Investment securities held-to-maturity The carrying amounts of investments held-to-maturity approximate fair value. Investment Securities For debt investment securities, which may include U.S. Treasury securities, obligations of other U.S. government agencies, obligations of states and political subdivisions and mortgage pass through and related securities, fair values are from an independent pricing service. The fair value measurements consider observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. See disclosures of fair value of investment securities in Note 2. Loans Fair values are estimated for portfolios of loans with similar financial characteristics. Loans are segregated by type such as commercial, real estate and consumer loans as outlined by regulatory reporting guidelines. Each category is segmented into fixed and variable interest rate terms and by performing and non-performing categories. 73 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) For variable rate performing loans, the carrying amount approximates the fair value. For fixed rate performing loans, except residential mortgage loans, the fair value is calculated by discounting scheduled cash flows through the estimated maturity using estimated market discount rates that reflect the credit and interest rate risk inherent in the loan. For performing residential mortgage loans, fair value is estimated by discounting contractual cash flows adjusted for prepayment estimates using discount rates based on secondary market sources or the primary origination market. Fixed rate performing loans are within Level 3 of the fair value hierarchy. At December 31, 2021 and December 31, 2020, the carrying amount of fixed rate performing loans was $1,363,313,000 and $1,812,413,000, respectively, and the estimated fair value was $1,323,223,000 and $1,747,257,000, respectively. Accrued Interest The carrying amounts of accrued interest approximate fair value. Deposits The fair value of deposits with no stated maturity, such as non-interest bearing demand deposit accounts, savings accounts and interest-bearing demand deposit accounts, was equal to the amount payable on demand as of December 31, 2021 and December 31, 2020. The fair value of time deposits is based on the discounted value of contractual cash flows. The discount rate is based on currently offered rates. Time deposits are within Level 3 of the fair value hierarchy. At December 31, 2021 and December 31, 2020, the carrying amount of time deposits was $2,188,803,000 and $2,153,541,000, respectively, and the estimated fair value was $2,186,547,000 and $2,148,976,000, respectively. Securities Sold Under Repurchase Agreements Securities sold under repurchase agreements are short-term maturities. Due to the contractual terms of the instruments, the carrying amounts approximated fair value at December 31, 2021 and December 31, 2020. Junior Subordinated Deferrable Interest Debentures We currently have floating rate junior subordinated deferrable interest debentures outstanding. Due to the contractual terms of the floating rate junior subordinated deferrable interest debentures, the carrying amounts approximated fair value at December 31, 2021 and December 31, 2020. Other Borrowed Funds We currently have long-term borrowings issued from the Federal Home Loan Bank (“FHLB”). The long-term borrowings outstanding at December 31, 2021 and December 31, 2020 are fixed-rate borrowings and the fair value is based on established market spreads for similar types of borrowings. The fixed-rate long-term borrowings are included in Level 2 of the fair value hierarchy. At December 31, 2021 and December 31, 2020 the carrying amount of the fixed-rate long-term FHLB borrowings was $436,138,000 and $436,372,000, respectively, and the estimated fair value was $455,187,000 and $480,475,000 respectively. Commitments to Extend Credit and Letters of Credit Commitments to extend credit and fund letters of credit are principally at current interest rates and therefore the carrying amount approximates fair value. Limitations Fair value estimates are made at a point in time, based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time of our entire holdings of a particular financial instrument. Because no market exists for a significant portion of our financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current 74 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters of significant judgment and therefore cannot be determined with precision. Changes in assumptions could significantly affect the estimates. Fair value estimates are based on existing on-and off-statement of condition financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. Other significant assets and liabilities that are not considered financial assets or liabilities include the bank premises and equipment and core deposit value. In addition, the tax ramifications related to the effect of fair value estimates have not been considered in the above estimates. 75 INTERNATIONAL BANCSHARES CORPORATION AND SUBSIDIARIES Notes to Consolidated Financial Statements (Continued) (21) International Bancshares Corporation (Parent Company Only) Financial Information Statements of Condition (Parent Company Only) December 31, 2021 and 2020 (Dollars in Thousands) ASSETS Cash . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .
