ITEM 2.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following is a discussion of our consolidated financial condition, changes in our financial condition and results of our operations, and should be read and reviewed in conjunction with the financial statements, and the notes thereto, in this Quarterly Report on Form 10-Q, and in our 2025 Form 10-K. Certain risks, uncertainties and other factors, including those set forth under “Risk Factors” in Part I, Item 1A. of the 2025 Form 10-K and elsewhere in this Quarterly Report on Form 10-Q, may cause actual results to differ materially from the results discussed in the forward-looking statements appearing in this discussion and analysis.

Forward-Looking Statements

Certain statements of other than historical fact that are contained in this report may be considered to be “forward-looking statements” within the meaning of and subject to the safe harbor protections of the Private Securities Litigation Reform Act of 1995.  These forward-looking statements are not guarantees of future performance, nor should they be relied upon as representing management’s views as of any subsequent date.  These statements may include words such as “expect,” “estimate,” “project,” “anticipate,” “appear,” “believe,” “could,” “should,” “may,” “might,” “will,” “would,” “seek,” “intend,” “probability,” “risk,” “goal,” “target,” “objective,” “plans,” “potential,” and similar expressions. Forward-looking statements are statements with respect to our beliefs, plans, expectations, objectives, goals, anticipations, assumptions, estimates, intentions and future performance and are subject to significant known and unknown risks and uncertainties, which could cause our actual results to differ materially from the results discussed in the forward-looking statements.  For example, trends in asset quality, capital, liquidity, our ability to sell nonperforming assets, expense reductions, planned operational efficiencies and earnings from growth and certain market risk disclosures, including the impact of interest rates and our expectations regarding rate changes, tax reform, inflation, the impacts related to or resulting from other economic factors are based upon information presently available to management and are dependent on choices about key model characteristics and assumptions and are subject to various limitations.  By their nature, certain of the market risk disclosures are only estimates and could be materially different from what actually occurs in the future.  Accordingly, our results could materially differ from those that have been estimated.  The most significant factors that could cause future results to differ materially from those anticipated by our forward-looking statements include general economic conditions in our markets, including higher energy and gas prices, the impact of changes in interest rates on our financial projections, models and guidance, as well as the effects of declines in the real estate market, tariffs or trade wars (including reduced consumer spending, lower economic growth or recession, reduced demand for U.S. exports, disruptions to supply chains and decreased demand for other banking products and services), high unemployment and increasing insurance costs, as well as the financial stress to borrowers as a result of the foregoing, all of which could impact economic growth and could cause a reduction in financial transactions and business activities, including decreased deposits and reduced loan originations and our ability to manage liquidity in a rapidly changing and unpredictable market. Other factors that could cause actual results to differ materially from those indicated by forward-looking statements include, but are not limited to, the following:

•general (i) political conditions, including, without limitation, governmental action and uncertainty resulting from U.S. and global political trends and (ii) economic conditions, either globally, nationally, in the State of Texas, or in the specific markets in which we operate, including, without limitation, the deterioration of the commercial real estate, residential real estate, construction and development, energy, oil and gas, credit or liquidity markets, which could cause an adverse change in our net interest margin, or a decline in the value of our assets, which could result in realized losses, as well as the risks of an economic slowdown or recession and the effects of inflationary pressures, changes in interest rates, tariffs or trade wars (including reduced consumer spending, supply chain issues and adverse impacts to credit quality) and the related financial stress on borrowers and changes to customer behavior and credit risk as a result of the foregoing;

•changes in trade, monetary, and fiscal policies and laws, including actual changes in interest rates and the Fed Funds rate and changes in international trade policies, tariffs and treaties affecting imports and exports, and their related impacts on macroeconomic conditions, customer behavior, funding costs and loan and securities portfolios;

•inflation and fluctuations in interest rates that reduce our margins and yields, the fair value of financial instruments, the level of loan originations or prepayments on loans we have made and make, and the cost we pay to retain and attract deposits and secure other types of funding;

•current or future legislation, regulatory changes or changes in monetary or fiscal policy that adversely affect the businesses in which we or our customers or our borrowers are engaged, including the Federal Reserve’s actions to manage interest rates, tariffs, trade policies, supply chain disruptions, immigration policies and/or disputes and other regulatory responses to economic conditions;

•the impact of interest rate fluctuations on our financial projections, models and guidance;

•legislative, tax and regulatory changes, including those that impact the money supply, trade, immigration and inflation;

•acts of terrorism, war or other conflicts, natural disasters, such as hurricanes, freezes, flooding and other man-made disasters, such as oil spills or power outages, health emergencies, epidemics or pandemics, climate change or other catastrophic events that may affect general economic conditions or cause other disruptions and/or increase costs, including, but not limited to, property and casualty and other insurance costs;

•potential impacts of the adverse developments in the banking industry highlighted by high-profile bank failures, including impacts on customer confidence, deposit outflows, liquidity and the regulatory response thereto (including increases in the cost of our deposit insurance assessments);

•technological changes, including potential cyber-security incidents and other disruptions, developments in AI, or innovations to the financial services industry, including as a result of the increased telework environment;

•our ability to identify and address cyber-security risks such as data security breaches, malware, “denial of service” attacks, “hacking” and identity theft, which may be exacerbated by developments in generative AI and which could disrupt our business and result in the disclosure of and/or misuse or misappropriation of confidential or proprietary information, disruption or damage of our systems, increased costs, significant losses, or adverse effects to our reputation;

•changes in the interest rate yield curve such as flat, inverted or steep yield curves, or changes in the interest rate environment that impact net interest margins and may impact prepayments on our MBS portfolio;

•the risk that our enterprise risk management framework, compliance program or our corporate governance and supervisory oversight functions may not identify or address risks adequately, which may result in unexpected losses;

•the effect of compliance with legislation or regulatory changes;

•credit risks of borrowers, including any increase in those risks due to changing economic conditions, including inflation, interest rates, tariffs and immigration policies;

•increases in our nonperforming assets;

•risks related to environmental liability as a result of certain lending activity;

•our ability to maintain adequate liquidity to fund operations and growth;

•our ability to control interest rate risk;

•any applicable regulatory limits or other restrictions on the Bank and its ability to pay dividends to us;

•the failure of our assumptions underlying our allowance for credit losses and other estimates;

•the failure to maintain an effective system of controls and procedures, including internal control over financial reporting;

•the effectiveness of our derivative financial instruments and hedging activities to manage risk;

•unexpected outcomes of, and the costs associated with, existing or new litigation involving us;

•potential claims, damages, penalties, fines and reputational damage resulting from pending or future litigation, regulatory proceedings and enforcement actions;

•changes impacting our balance sheet strategy;

•risks related to actual mortgage prepayments diverging from projections;

•risks related to fluctuations in the price per barrel of crude oil, including as a result of recent conflict in the Middle East;

•significant increases in competition in the banking and financial services industry;

•changes in consumer spending, borrowing and saving habits, including as a result of inflation, tariffs, supply chain disruptions, fluctuating interest rates and recessionary concerns;

•execution of future acquisitions, reorganization or disposition transactions, including the risk that the anticipated benefits of such transactions are not realized;

•our ability to increase market share and control expenses;

•our ability to develop competitive new products and services in a timely manner and the acceptance of such products and services by our customers;

•the effect of changes in accounting policies and practices;

•adverse changes in the status or financial condition of the GSEs which impact the GSEs’ guarantees or ability to pay or issue debt;

•adverse changes in the credit portfolios of other U.S. financial institutions relative to the performance of certain of our investment securities;

•risks related to actual U.S. agency MBS prepayments exceeding projected prepayment levels;

•risks related to U.S. agency MBS prepayments increasing due to U.S. government programs designed to assist homeowners to refinance their mortgage that might not otherwise have qualified;

•risks related to loans secured by real estate, including the risk that the value and marketability of collateral could decline;

•risks associated with our common stock and our other securities, including fluctuations in our stock price and general volatility in the stock market; and

•other risks and uncertainties discussed in “Part I – Item 1A. Risk Factors” in the 2025 Form 10-K.

All written or oral forward-looking statements made by us or attributable to us are expressly qualified by this cautionary notice.  We disclaim any obligation to update any factors or to announce publicly the result of revisions to any of the forward-looking statements included herein to reflect future events or developments, unless otherwise required by law.
