Background

Texas Capital Bancshares, Inc. (“the Company”), a Delaware financial holding company, is the parent of Texas Capital Bank, National Association (“the Bank”), a Texas-based bank headquartered in Dallas, with our primary banking offices in Austin, Dallas, Fort Worth, Houston, and San Antonio, the state’s five largest metropolitan areas. All of our business activities are conducted through our bank subsidiary. Our market focus is commercial businesses and successful professionals and entrepreneurs, and we offer a variety of banking products and services to our customers. We have focused on organic growth, maintenance of credit quality and bankers with strong personal and professional relationships in their communities.

We focus on serving the needs of commercial businesses and successful professionals and entrepreneurs, the core of our model since our organization in March 1998. We do not incur the costs of competing in an over-branched and over-crowded consumer market. We are primarily a secured lender in Texas, and, as a result, we have experienced a low percentage of charge-offs relative to both total loans and non-performing loans since inception. Our loan portfolio is diversified by industry, collateral and geography in Texas.

Growth History

We have grown substantially in both size and profitability since our formation. The table below sets forth data regarding the growth of key areas of our business from December 2008 through December 2012 (in thousands):

The following table provides information about the growth of our loan portfolio by type of loan from December 2008 to December 2012 (in thousands):

The Texas Market

The Texas market for banking services is highly competitive. Texas’ largest banking organizations are headquartered outside of Texas and are controlled by out-of-state organizations. We also compete with other providers of financial services, such as savings and loan associations, credit unions, consumer finance

companies, securities firms, insurance companies, commercial finance and leasing companies, full service brokerage firms and discount brokerage firms. We believe that many middle market companies and successful professionals and entrepreneurs are interested in banking with a company headquartered in, and with decision-making authority based in, Texas and with established Texas bankers who have the expertise to act as trusted advisors to the customer with regard to its banking needs. Our banking centers in our target markets are served by experienced bankers with lending expertise in the specific industries found in their market areas and established community ties. We believe our bank can offer customers more responsive and personalized service. We believe that, if we service these customers properly, we will be able to establish long-term relationships and provide multiple products to our customers, thereby enhancing our profitability.

Business Strategy

Utilizing the business and community ties of our management and their banking experience, our strategy is maintaining a primary focus on middle market business customers and successful professionals and entrepreneurs in each of the five major metropolitan markets of Texas. In addition, we have specialty lending businesses that have a national presence that also focus on middle market customer relationships. To achieve this, we seek to implement the following strategies:

Products and Services

We offer a variety of loan, deposit account and other financial products and services to our customers.

Business Customers. We offer a full range of products and services oriented to the needs of our business customers, including:

Individual Customers. We also provide complete banking services for our individual customers, including:

Lending Activities

We target our lending to middle market businesses and successful professionals and entrepreneurs that meet our credit standards. The credit standards are set by our standing Credit Policy Committee with the assistance of our Bank’s Chief Credit and Risk Officer, who is charged with ensuring that credit standards are met by loans in our portfolio. Our Credit Policy Committee is comprised of senior Bank officers including our Bank’s Chief Executive Officer, our Bank’s President/Chief Lending Officer and our Bank’s Chief Credit and Risk Officer. We believe we have maintained a diversified loan portfolio. Credit policies and underwriting guidelines are tailored to address the unique risks associated with each industry represented in the portfolio. Our credit standards for commercial borrowers reference numerous criteria with respect to the borrower, including historical and projected financial information, strength of management, acceptable collateral and associated advance rates, and market conditions and trends in the borrower’s industry. In addition, prospective loans are also analyzed based on current industry concentrations in our loan portfolio to prevent an unacceptable concentration of loans in any particular industry. We believe our credit standards are consistent with achieving business objectives in the markets we serve and will generally mitigate risks. We believe that we differentiate our bank from its competitors by focusing on and aggressively marketing to our core customers and accommodating, to the extent permitted by our credit standards, their individual needs.

We generally extend variable rate loans in which the interest rate fluctuates with a predetermined indicator such as the United States prime rate or the London Interbank Offered Rate (LIBOR). Our use of variable rate loans is designed to protect us from risks associated with interest rate fluctuations since the rates of interest earned will automatically reflect such fluctuations.

Deposit Products

We offer a variety of deposit products to our core customers at interest rates that are competitive with other banks. Our business deposit products include commercial checking accounts, lockbox accounts, cash concentration accounts, and other treasury management services, including an on-line system. Our treasury management on-line system offers information services, wire transfer initiation, ACH initiation, account transfer, and service integration. Our consumer deposit products include checking accounts, savings accounts, money market accounts and certificates of deposit. We also allow our consumer deposit customers to access their accounts, transfer funds, pay bills and perform other account functions over the Internet and through ATM machines.

Trust and Wealth Management

Our trust and wealth management services include investment management, personal trust and estate services, custodial services, retirement accounts and related services. Our investment management professionals work with our clients to define objectives, goals and strategies for their investment portfolios. We assist the customer with the selection of an investment manager and work with the client to tailor the investment program accordingly. We also offer retirement products such as individual retirement accounts and administrative services for retirement vehicles such as pension and profit sharing plans.

Cayman Islands Branch

In June 2003, we received authorization from the Cayman Islands Monetary Authority to establish a branch of our bank in the Cayman Islands. We believe that a Cayman Islands branch of our bank enables us to offer more competitive cash management and deposit products to our core customers. Our Cayman Islands branch consists of an agented office to facilitate our offering of these products. We opened our Cayman Islands branch in September 2003. All deposits in the Cayman Branch come from U.S. based customers of our Bank. Deposits do not originate from foreign sources, and funds transfers neither come from nor go to facilities outside of the U.S. All deposits are in U.S. dollars. As of December 31, 2012, our Cayman Islands deposits totaled $329.3 million.

Employees

As of December 31, 2012, we had 881 full-time employees relating to our continuing operations. None of our employees is represented by a collective bargaining agreement and we consider our relations with our employees to be good.

Regulation and Supervision

Current banking laws contain numerous provisions affecting various aspects of our business. Our bank is subject to federal banking laws and regulations that impose specific requirements on and provide regulatory oversight of virtually all aspects of our operations. These laws and regulations are generally intended for the protection of depositors, the deposit insurance funds of the Federal Deposit Insurance Corporation, or the FDIC, and the banking system as a whole, rather than for the protection of our stockholders. Banking regulators have broad enforcement powers over financial holding companies and banks and their affiliates, including the power to establish regulatory requirements, impose large fines and other penalties for violations of laws and regulations. The following is a brief summary of laws and regulations to which we are subject.

National banks such as our bank are subject to examination by the Office of the Comptroller of the Currency, or the OCC. The OCC and the FDIC regulate or monitor all areas of a national bank’s operations, including security devices and procedures, adequacy of capitalization and loss reserves, accounting treatment and impact on capital determinations, loans, investments, borrowings, deposits, mergers, issuances of securities, payment of dividends, interest rate risk management, establishment of branches, corporate reorganizations, maintenance of books and records, and adequacy of staff training to carry on safe lending and deposit gathering practices. The OCC requires national banks to maintain capital ratios and imposes limitations on its aggregate investment in real estate, bank premises and furniture and fixtures. National banks are currently required by the OCC to prepare quarterly reports on their financial condition and to conduct an annual audit of their financial affairs in compliance with minimum standards and procedures prescribed by the OCC.

Restrictions on Dividends and Repurchases. Our source of funding to pay dividends is our bank. Our bank is subject to statutory dividend restrictions. Under such restrictions, national banks may not, without the prior approval of the OCC, declare dividends in excess of the sum of the current year’s net profits plus the retained net profits from the prior two years, less any required transfers to surplus. In addition, under the Federal Deposit Insurance Corporation Improvement Act of 1991, our bank may not pay any dividend if payment would cause it to become undercapitalized or in the event it is undercapitalized.

It is the policy of the Federal Reserve, which regulates financial holding companies such as ours, that financial holding companies should pay cash dividends on common stock only out of income available over the past year and only if prospective earnings retention is consistent with the organization’s expected future needs and financial condition. The policy provides that financial holding companies should not maintain a level of cash dividends that undermines the financial holding company’s ability to serve as a source of strength to its banking subsidiaries.

If, in the opinion of the applicable federal bank regulatory authority, a depository institution or holding company is engaged in or is about to engage in an unsound practice (which could include the payment of

4

Table of Contents

dividends), such authority may require, generally after notice and hearing, that such institution or holding company cease and desist such practice. The federal banking agencies have indicated that paying dividends that deplete a depository institution’s or holding company’s capital base to an inadequate level would be such an unsafe banking practice. Moreover, the Federal Reserve and the FDIC have issued policy statements providing that financial holding companies and insured depository institutions generally should only pay dividends out of current operating earnings.

Supervision by the Federal Reserve. We operate as a financial holding company registered under the Bank Holding Company Act, and, as such, we are subject to supervision, regulation and examination by the Federal Reserve. The Bank Holding Company Act and other Federal laws subject financial holding companies to particular restrictions on the types of activities in which they may engage, and to a range of supervisory requirements and activities, including regulatory enforcement actions for violations of laws and regulations.

Because we are a legal entity separate and distinct from our bank, our right to participate in the distribution of assets of any subsidiary upon the subsidiary’s liquidation or reorganization will be subject to the prior claims of the subsidiary’s creditors. In the event of a liquidation or other resolution of a subsidiary, the claims of depositors and other general or subordinated creditors are entitled to a priority of payment over the claims of holders of any obligation of the institution to its stockholders, including any financial holding company (such as ours) or any stockholder or creditor thereof.

Support of Subsidiary Banks. Under Federal Reserve policy, a financial holding company is expected to act as a source of financial and managerial strength to each of its banking subsidiaries and commit resources to their support. Such support may be required at times when, absent this Federal Reserve policy, a holding company may not be inclined to provide it. As discussed below, a financial holding company in certain circumstances could be required to guarantee the capital plan of an undercapitalized banking subsidiary in order for it to be accepted by the regulators.

In the event of a financial holding company’s bankruptcy under Chapter 11 of the U.S. Bankruptcy Code, the bankruptcy trustee will be deemed to have assumed and is required to cure immediately any deficit under any commitment by the debtor holding company to any of the federal banking agencies to maintain the capital of an insured depository institution, and any claim for breach of such obligation will generally have priority over most other unsecured claims.

Capital Adequacy Requirements. The bank regulators have adopted a system using risk-based capital guidelines to evaluate the capital adequacy of banking organizations. Under the guidelines, specific categories of assets and off-balance sheet activities such as letters of credit are assigned different risk weights, based generally on the perceived credit or other risks associated with the asset. These risk weights are multiplied by corresponding asset balances to determine a “risk weighted” asset base. The guidelines require a minimum total risk-based capital ratio of 8% (of which at least 4% is required to consist of Tier 1 capital elements).

In addition to the risk-based capital guidelines, the OCC and the Federal Reserve use a leverage ratio as an additional tool to evaluate the capital adequacy of banking organizations. The leverage ratio is a company’s Tier 1 capital divided by its average total consolidated assets. Banking organizations must maintain a minimum leverage ratio of at least 4%, although most organizations are expected to maintain leverage ratios that are at least 100 to 200 basis points above this minimum ratio.

The federal banking agencies’ risk-based and leverage capital ratios are minimum supervisory ratios generally applicable to banking organizations that meet specified criteria, assuming that they have the highest regulatory rating. Banking organizations not meeting these criteria are expected to operate with capital positions well above the minimum ratios. The federal bank regulatory agencies may set capital requirements for a particular banking organization that are higher than the minimum ratios when circumstances warrant and the agencies can change interpretations of existing guidelines, which changes could result in decreases in our capital ratios. Federal Reserve and OCC guidelines also provide that banking organizations experiencing significant internal growth or making acquisitions will be expected to

5

Table of Contents

maintain strong capital positions substantially above the minimum supervisory levels, without significant reliance on intangible assets. In addition, the regulations of the bank regulators provide that concentration of credit risks arising from non-traditional activities, as well as an institution’s ability to manage these risks, are important factors to be taken into account by regulatory agencies in assessing an organization’s overall capital adequacy. Regulators can, from time to time, change their policies or interpretations of practices in such a way that could require a change in risk weight, which could ultimately require the bank to provide additional capital to support future growth or reduce asset balances to maintain minimum and well-capitalized levels.

Transactions with Affiliates and Insiders. Our bank is subject to Section 23A of the Federal Reserve Act which places limits on, among other covered transactions, the amount of loans or extensions of credit to affiliates that it may make. In addition, extensions of credit must be collateralized by Treasury securities or other collateral in prescribed amounts. It also limits the amount of advances to third parties which are collateralized by our securities or obligations or the securities or obligations of any of our non-banking subsidiaries.

Our bank also is subject to Section 23B of the Federal Reserve Act, which, among other things, prohibits an institution from engaging in transactions with affiliates unless the transactions are on terms substantially the same, or at least as favorable to such institution or its subsidiaries, as those prevailing at the time for comparable transactions with non-affiliates.

We are subject to restrictions on extensions of credit to executive officers, directors, principal stockholders and their related interests. These restrictions contained in the Federal Reserve Act and Federal Reserve Regulation O apply to all insured institutions and their subsidiaries and holding companies. These restrictions include limits on loans to one borrower and conditions that must be met before such a loan can be made. There is also an aggregate limitation on all loans to insiders and their related interests. These loans cannot exceed the institution’s total unimpaired capital and surplus, and the FDIC may determine that a lesser amount is appropriate. Insiders are subject to enforcement actions for knowingly accepting loans in violation of applicable restrictions. See additional restrictions on transactions with affiliates and insiders discussed in the Dodd-Frank Act section.

Corrective Measures for Capital Deficiencies. The Federal Deposit Insurance Corporation Improvement Act imposes a regulatory matrix which requires the federal banking agencies, which include the FDIC, the OCC and the Federal Reserve, to take “prompt corrective action” with respect to capital deficient institutions. The prompt corrective action provisions subject undercapitalized institutions to an increasingly stringent array of restrictions, requirements and prohibitions as their capital levels deteriorate. Should these corrective measures prove unsuccessful in recapitalizing the institution and correcting its problems, the Federal Deposit Insurance Corporation Improvement Act mandates that the institution be placed in receivership.

Pursuant to regulations promulgated under the Federal Deposit Insurance Corporation Improvement Act, the corrective actions that the banking agencies either must or may take are tied primarily to an institution’s capital levels. In accordance with the framework adopted by the Federal Deposit Insurance Corporation Improvement Act, the banking agencies have developed a classification system, pursuant to which all banks and thrifts are placed into one of five categories. Agency regulations define, for each capital category, the levels at which institutions are “well capitalized”, “adequately capitalized”, “undercapitalized”, “significantly undercapitalized” and “critically undercapitalized.” A well capitalized bank has a total risk-based capital ratio (total capital to risk-weighted assets) of 10% or higher; a Tier 1 risk-based capital ratio (Tier 1 capital to risk-weighted assets) of 6% or higher; a leverage ratio (Tier 1 capital to total adjusted assets) of 5% or higher; and is not subject to any written agreement, order or directive requiring it to maintain a specific capital level for any capital measure. An institution is critically undercapitalized if it has a tangible equity to total assets ratio that is equal to or less than 2%. Our bank’s total risk-based capital ratio was 10.34% at December 31, 2012 and, as a result, it is currently classified as “well capitalized” for purposes of the OCC’s prompt corrective action regulations. The bank’s capital category of “well capitalized” is determined solely for the purposes of applying prompt corrective action

and that the capital category may not constitute an accurate representation of the bank’s overall financial condition or prospects. The OCC, Federal Reserve and FDIC may, pursuant to changes in their regulatory or statutory interpretations, change risk weights applicable to different assets and determine that additional capital may be required to support future growth.

In addition to requiring undercapitalized institutions to submit a capital restoration plan which must be guaranteed by its holding company (up to specified limits) in order to be accepted by the bank regulators, agency regulations contain broad restrictions on activities of undercapitalized institutions including asset growth, acquisitions, branch establishment and expansion into new lines of business. With some exceptions, an insured depository institution is prohibited from making capital distributions, including dividends, and is prohibited from paying management fees to control persons if the institution would be undercapitalized after any such distribution or payment.

As an institution’s capital decreases, the OCC’s enforcement powers become more severe. A significantly undercapitalized institution is subject to mandated capital raising activities, restrictions on interest rates paid and transactions with affiliates, removal of management and other restrictions. The OCC has only very limited discretion in dealing with a critically undercapitalized institution and is virtually required to appoint a receiver or conservator (the FDIC) if the capital deficiency is not corrected promptly.

Banks with risk-based capital and leverage ratios below the required minimums may also be subject to certain administrative actions, including the termination of deposit insurance upon notice and hearing, or a temporary suspension of insurance without a hearing in the event the institution has no tangible capital.

BASEL III. On December 15, 2010, the Basel Committee released its final framework for strengthening international capital and liquidity regulation, known as Basel III. When fully phased in on January 1, 2019, Basel III requires banks to maintain the following new standards and introduces a new capital measure “Common Equity Tier 1”, or “CET1”. Basel III increases the CET1 to risk-weighted assets to 4.5%, and introduces a capital conservation buffer of an additional 2.5% of common equity to risk-weighted assets, raising the target CET1 to risk-weighted assets ratio to 7%. It requires banks to maintain a minimum ratio of Tier 1 capital to risk weighted assets of at least 6.0%, plus the capital conservation buffer effectively resulting in Tier 1 capital ratio of 8.5%. Basel III increases the minimum total capital ratio to 8.0% plus the capital conservation buffer, increasing the minimum total capital ratio to 10.5%. Basel III also introduces a non-risk adjusted tier 1 leverage ratio of 3%, based on a measure of total exposure rather than total assets, and new liquidity standards. The Basel III capital and liquidity standards will be phased in over a multi-year period, but the implementation of the new framework will commence January 1, 2013. On that date, banks will be required to meet the following minimum capital ratios: 3.5% CET1 to risk-weighted assets, 4.5% Tier 1 capital to risk-weighted assets and 8.0% total capital to risk-weighted assets. Basel III also requires the phase-out from Tier 1 Capital of trust preferred securities over a 10-year time period beginning on January 1, 2013. It requires the phase-out of these instruments for bank holding companies having under $15 billion in total consolidated assets as of December 31, 2009, albeit on Basel III’s longer 10-year phase-out, permitting the inclusion of 90% of the carrying value of such instruments in 2013, with annual 10% decreases in the includible amount through 2021, until the instruments are fully phased-out on January 1, 2022.

Although the Basel III framework is not directly binding on the U.S. bank regulatory agencies, the regulatory agencies will likely implement changes to the capital adequacy standards applicable to the insured depository institutions and their holding companies in light of Basel III. In June 2012, the U.S. bank regulatory agencies issued three proposals to implement the capital, liquidity and other requirements under BASEL III, as well as certain other regulatory capital requirements under the Dodd-Frank Act. In November 2012, the Federal Reserve and FDIC released notice that the Basel III Notices of Proposed Rulemaking they issued in June will not be finalized and effective by January 1, 2013. They have not clarified an intended target date for implementation, but have stated that they will take “operational and other considerations” into account when they finalize implementation dates/transition periods.

Sarbanes-Oxley Act of 2002. The Sarbanes-Oxley Act of 2002 (“Sarbanes-Oxley”) contains important requirements for public companies in the area of financial disclosure and corporate governance. In

7

Table of Contents

accordance with Section 302(a) of Sarbanes-Oxley, written certifications by our chief executive officer and chief financial officer are required. These certifications attest that our quarterly and annual reports do not contain any untrue statement of a material fact.

Financial Modernization Act of 1999. The Gramm-Leach-Bliley Financial Modernization Act of 1999 (“the Modernization Act”):

The Modernization Act also modifies other current financial laws, including laws related to financial privacy. The financial privacy provisions generally prohibit financial institutions, including us, from disclosing non-public personal financial information to non-affiliated third parties unless customers have the opportunity to “opt out” of the disclosure.

Community Reinvestment Act. The Community Reinvestment Act of 1977 (“CRA”) requires depository institutions to assist in meeting the credit needs of their market areas consistent with safe and sound banking practice. Under the CRA, each depository institution is required to help meet the credit needs of its market areas by, among other things, providing credit to low- and moderate-income individuals and communities. Depository institutions are periodically examined for compliance with the CRA and are assigned ratings. In order for a financial holding company to commence new activity permitted by the Bank Holding Company Act, each insured depository institution subsidiary of the financial holding company must have received a rating of at least “satisfactory” in its most recent examination under the CRA.

The USA Patriot Act, the International Money Laundering Abatement and Financial Anti-Terrorism Act and the Bank Secrecy Act. A major focus of governmental policy on financial institutions in recent years has been aimed at combating money laundering and terrorist financing. The USA Patriot Act of 2001 and the International Money Laundering Abatement and Financial Anti-Terrorism Act of 2001 substantially broadened the scope of United States anti-money laundering laws and penalties, specifically related to the Bank Secrecy Act, and expanded the extra-territorial jurisdiction of the United States. The United States Treasury Department has issued a number of implementing regulations which apply various requirements of the USA Patriot Act to financial institutions such as our bank. These regulations impose obligations on financial institutions to maintain appropriate policies, procedures and controls to detect, prevent and report money laundering and terrorist financing and to verify the identity of their customers. Failure of a financial institution to maintain and implement adequate programs to combat money laundering and terrorist financing, or to comply with relevant laws or regulations, could have serious legal, reputational and financial consequences for the institution. Because of the significance of regulatory emphasis on these requirements, we will continue to expend significant staffing, technology and financial resources to maintain programs designed to ensure compliance with applicable laws and regulations and an effective audit function for testing our compliance with the Bank Secrecy Act on an ongoing basis.

The Dodd-Frank Act. On July 21, 2010, President Obama signed the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 Act (“Dodd-Frank Act”) into law. The Dodd-Frank Act will have a broad impact on the financial services industry, imposing significant regulatory and compliance changes, including the designation of certain financial companies as systemically significant, the imposition of increased capital, leverage, and liquidity requirements, and numerous other provisions designed to improve supervision and oversight of, and strengthen safety and soundness within, the financial services sector.

Additionally, the Dodd-Frank Act establishes a new framework of authority to conduct systemic risk oversight within the financial system to be distributed among new and existing federal regulatory agencies, including the Financial Stability Oversight Council, or Council, the Federal Reserve, the OCC, and the FDIC.

The following items provide a brief description of certain provisions of the Dodd-Frank Act that may have an effect on us.

Table of Contents

Many requirements of the Dodd-Frank Act will be implemented over time and most will be subject to regulations implemented over the course of several years. Given the uncertainty associated with the manner in which the provisions of the Dodd-Frank Act will be implemented by the various regulatory agencies and through regulations, the full extent of the impact such requirements will have on our operations is unclear. The changes resulting from the Dodd-Frank Act may impact the profitability of our business activities, require changes to certain of our business practices, impose upon us more stringent capital, liquidity and leverage requirements or otherwise adversely affect our business. These changes may also require us to invest significant management attention and resources to evaluate and make any changes necessary to comply with new statutory and regulatory requirements. Failure to comply with the new requirements may negatively impact our results of operations and financial condition. While we cannot predict what effect any presently contemplated or future changes in the laws or regulations or their interpretations would have on us, these changes could be materially adverse to our investors.

An investment in our common stock involves certain risks. You should consider carefully the following risks and other information in this report, including our financial information and related notes, before investing in our common stock. The risks and uncertainties described below are not the only ones facing us. Additional risks and uncertainties that management is not aware of or focused on or that management currently deems immaterial may also impair our business operations. This report is qualified in its entirety by these risk factors.

Risk Factors Associated With Our Business

We must effectively manage our credit risk .    There are risks inherent in making any loan, including risks with respect to the period of time over which the loan may be repaid, risks resulting from changes in economic and industry conditions, risks inherent in dealing with individual borrowers, including increased risks of

10

Table of Contents

fraud perpetrated by customers of the bank and risks resulting from uncertainties as to the future value of collateral. The risk of non-payment of loans is inherent in commercial banking. Although we attempt to minimize our credit risk by carefully monitoring the concentration of our loans within specific industries and through prudent loan approval practices in all categories of our lending, we cannot assure you that such monitoring and approval procedures will reduce these lending risks. We cannot assure you that our credit administration personnel, policies and procedures will adequately adapt to changes in economic or any other conditions affecting customers and the quality of the loan portfolio.

Our results of operations and financial condition would be adversely affected if our allowance for loan losses is not sufficient to absorb actual losses .    Experience in the banking industry indicates that a portion of our loans in all categories of our lending business will become delinquent, and some may only be partially repaid or may never be repaid at all. Our methodology for establishing the adequacy of the allowance for loan losses depends on subjective application of risk grades as indicators of borrowers’ ability to repay. Deterioration in general economic conditions and unforeseen risks affecting customers may have an adverse effect on borrowers’ capacity to repay timely their obligations before risk grades could reflect those changing conditions. In times of improving credit quality, with growth in our loan portfolio, the allowance for loan losses may decrease as a percent of total loans. Changes in economic and market conditions may increase the risk that the allowance would become inadequate if borrowers experience economic and other conditions adverse to their businesses. Maintaining the adequacy of our allowance for loan losses may require that we make significant and unanticipated increases in our provisions for loan losses, which would materially affect our results of operations and capital adequacy. Recognizing that many of our loans individually represent a significant percentage of our total allowance for loan losses, adverse collection experience in a relatively small number of loans could require an increase in our allowance. Federal regulators, as an integral part of their respective supervisory functions, periodically review our allowance for loan losses. The regulatory agencies may require us to change classifications or grades on loans, increase the allowance for loan losses with large provisions for loan losses and to recognize further loan charge-offs based upon their judgments, which may be different from ours. Any increase in the allowance for loan losses required by these regulatory agencies could have a negative effect on our results of operations and financial condition. Additionally, the current proposal from the Financial Accounting Standards Board (“FASB”) for changes to the credit impairment model could require us to increase our allowance for loan losses, and that could have a negative effect on our results of operations and financial condition.

Our growth plans are dependent on the availability of capital and funding .    Our historical ability to raise capital through the sale of common stock and debt securities may become limited by market conditions beyond our control, as has been evidenced with the economic downturn and issues affecting the financial services industry. Due to changes in regulation, trust preferred is no longer viable as source of long-term debt capital, and treatment of trust preferred as capital may be changed by regulation prior to the maturity of the trust preferred. Change in capital treatment of trust preferred may require the Company to issue securities at times and with maturity, conditions, and rates that are disadvantageous. Pricing of capital, in terms of interest or dividend requirements or dilutive impact on earnings available to shareholders, has increased dramatically, and an increase in costs of capital can have a direct impact on operating performance and the ability to achieve growth objectives. Costs of funding could also increase dramatically and affect our growth objectives, as well as our financial performance. Additionally, the FDIC’s guarantee on non-interest bearing deposits was not extended past December 31, 2012; as a result, we could be adversely affected in our ability to attract and maintain non-interest bearing deposits as a source of cost-effective funding. Adverse changes in operating performance or financial condition or changes in statutory or regulatory requirements could make raising additional capital difficult or extremely expensive. Regulators may change capital requirements including previous interpretations of practices related to risk weights that could require us to raise additional capital or reduce asset balances to maintain minimum and well-capitalized levels of regulatory capital. One such change could relate to the assets generated by our mortgage warehouse division. Balances shown as “loans held for sale” are comprised of ownership interests in mortgage loans to which we currently assign a risk weight applicable under current regulation to mortgage loans (50% or 20% for loans guaranteed by the FHA or VA). The OCC is considering whether assets which do not qualify as “participating interests” under ASC 860, should be assigned to the 100% risk weight category associated

with loans to mortgage companies that are secured by a pledge of mortgage loans as collateral. We believe we have applied the correct risk weights to the ownership interests in mortgage loans held by us and are prepared to defend that position. We cannot predict the likelihood of our success if the OCC chooses to contest risk weights currently applied. We believe our business practices could be changed to maintain the risk weights currently applied, but those changes would create operating and financial risks to which the Bank currently is not exposed. The outcome of a review by the OCC of our approach to the application of risk weights to the ownership interests in mortgage assets is uncertain. An increase in risk weights applied could require the Bank to obtain additional capital to support future growth or reduce our loans held for sale to the detriment of our operating results.

Our operations are significantly affected by interest rate levels .    Our profitability is dependent to a large extent on our net interest income, which is the difference between interest income we earn as a result of interest paid to us on loans and investments and interest we pay to third parties such as our depositors and those from whom we borrow funds. Like most financial institutions, we are affected by changes in general interest rate levels, which are currently at record low levels, and by other economic factors beyond our control. Prolonged periods of unusually low interest rates may have an adverse effect on earnings or returns by reducing yields on loans and other earning assets and by reducing the value of demand deposits, stockholders’ equity and fixed rate liabilities with rates higher than available earning assets. Interest rate risk can result from mismatches between the dollar amount of repricing or maturing assets and liabilities and from mismatches in the timing and rate at which our assets and liabilities reprice. Although we have implemented strategies which we believe reduce the potential effects of changes in interest rates on our results of operations, these strategies will not always be successful. In addition, any substantial and prolonged increase in market interest rates could reduce our customers’ desire to borrow money from us or adversely affect their ability to repay their outstanding loans by increasing their costs since most of our loans have adjustable interest rates that reset periodically. If our borrowers’ ability to repay is affected, our level of non-performing assets would increase and the amount of interest earned on loans would decrease, thereby having an adverse effect on operating results. Additionally, the level of interest rates may have a direct impact on the levels of mortgage origination and could affect the volumes and the profitability of our warehouse lending business. Any of these events could adversely affect our results of operations or financial condition.

Our business faces unpredictable economic and business conditions .    General economic conditions and specific business conditions impact the banking industry and our customers’ businesses. The credit quality of our loan portfolio necessarily reflects, among other things, the general economic conditions in the areas in which we conduct our business. Our continued financial success depends somewhat on factors beyond our control, including:

Substantial deterioration in any of the foregoing conditions, as we have experienced with the past economic downturn and continuation of weakened economy and employment growth, can have a material adverse effect on our results of operations and financial condition, and we may not be able to sustain our historical rate of growth. Our bank’s customer base is primarily commercial in nature, and our bank does not have a significant branch network or retail deposit base. In periods of economic downturn, business and commercial deposits may tend to be more volatile than traditional retail consumer deposits and, therefore, during these periods our financial condition and results of operations could be adversely affected to a greater degree than our competitors that have a larger retail customer base. We rely on investors to purchase our loans held for sale in a timely manner. Due to industry and economic conditions, investors may slow their purchase or refuse to purchase the loans.

12

Table of Contents

We are dependent upon key personnel .    Our success depends to a significant extent upon the performance of certain key employees, the loss of whom could have an adverse effect on our business. Although we have entered into employment agreements with certain employees, we cannot assure you that we will be successful in retaining key employees.

Our business is concentrated in Texas and a downturn in the economy of Texas may adversely affect our business .    A substantial majority of our business is located in Texas. As a result, our financial condition and results of operations may be affected by changes in the Texas economy. A prolonged period of economic recession or other adverse economic conditions in Texas may result in an increase in non-payment of loans, a decrease in collateral value and higher incidence of fraud.

Our business strategy focuses on organic growth within our target markets and, if we fail to manage our growth effectively, it could negatively affect our operations .    We intend to develop our business principally through organic growth. Our prospects must be considered in light of the risks, expenses and difficulties frequently encountered by companies in significant growth stages of development. In order to execute our growth strategy successfully, we must, among other things:

Failure to manage our growth effectively could have a material adverse effect on our business, future prospects, financial condition or results of operations, and could adversely affect our ability to successfully implement our business strategy.

Our business is susceptible to fraud. As a financial institution, we may experience fraud risk with our loan customers and deposit customers, both directly and indirectly. As a lender we rely on financial data which could turn out to be fraudulent, both when we’re the originator of a loan or when we are purchasing ownership interests in loans originated by others. We believe we have the underwriting and operational controls in place to prevent or detect, but in some cases of collusion with multiple parties the fraud might not be readily detected and could result in losses that would affect our financial results. In addition, our lending customers could experience fraud in their business which would have an effect on their ability to repay us. Our deposit customers could be victims of fraud that may not result from ineffective controls on our part, but we could be expected to share in losses as a result of, and as a means to maintain, our relationship with the customer.

We compete with many larger financial institutions which have substantially greater financial resources than we have .    Competition among financial institutions in Texas is intense. We compete with other financial and bank holding companies, state and national commercial banks, savings and loan associations, consumer finance companies, credit unions, securities brokerages, insurance companies, mortgage banking companies, money market mutual funds, asset-based non-bank lenders and other financial institutions. Many of these competitors have substantially greater financial resources, lending limits and larger branch networks than we do, and are able to offer a broader range of products and services than we can, including systems and services that could protect customers from cyber threats. Failure to compete effectively for deposit, loan and other banking customers in our markets could cause us to lose market share, slow our growth rate and may have an adverse effect on our financial condition and results of operations.

The risks involved in commercial lending may be material .    We generally invest a greater proportion of our assets in commercial loans than other banking institutions of our size, and our business plan calls for continued efforts to increase our assets invested in these loans. Commercial loans may involve a higher degree of credit risk than some other types of loans due, in part, to their larger average size, the effects of changing economic conditions on commercial loans, the dependency on the cash flow of the borrowers’ businesses to service debt, the sale of assets securing the loans, and disposition of collateral which may not be readily marketable. Losses incurred on a relatively small number of commercial loans could have a materially adverse impact on our results of operations and financial condition.

Real estate lending in our core Texas markets involves risks related to a decline in value of commercial and residential real estate .    Our real estate lending activities, and the exposure to fluctuations in real estate values, are significant and expected to increase. The market value of real estate can fluctuate significantly in a relatively short period of time as a result of market conditions in the geographic area in which the real estate is located. If the value of the real estate serving as collateral for our loan portfolio were to decline materially, a significant part of our loan portfolio could become under-collateralized and we may not be able to realize the amount of security that we anticipated at the time of originating the loan. Conditions in certain segments of the real estate industry, including homebuilding, lot development and mortgage lending, may have an effect on values of real estate pledged as collateral in our markets. The inability of purchasers of real estate, including residential real estate, to obtain financing may weaken the financial condition of borrowers dependent on the sale or refinancing of property. Failure to sell some loans held for sale in accordance with contracted terms may result in mark to market charges to other operating income. In addition, after the mark to market, we may transfer the loans into the loans held for investment portfolio where they will then be subject to changes in grade, classification, accrual status, foreclosure, or loss which could have an effect on the adequacy of the allowance for loan losses. When conditions warrant, we may find it beneficial to restructure loans to improve prospects of collectability, and such actions may require loans to be treated as troubled debt restructurings (“TDR”) and/or non-performing loans.

We are subject to environmental liability risk associated with lending activities. A significant portion of our loan portfolio is secured by real property. During the ordinary course of business, we may foreclose on and take title to properties securing certain loans. In doing so, there is a risk that hazardous or toxic substances could be found on these properties. If hazardous or toxic substances are found, we may be liable for remediation costs, as well as for personal injury and property damage. Environmental laws may require us to incur substantial expenses and may materially reduce the affected property’s value or limit our ability to use or sell the affected property. In addition, future laws or more stringent interpretations or enforcement policies with respect to existing laws may increase our exposure to environmental liability. Although we have policies and procedures to perform an environmental review before initiating any foreclosure action on real property, these reviews may not be sufficient to detect all potential environmental hazards. The remediation costs and any other financial liabilities associated with an environmental hazard could have a material adverse effect on our financial condition and results of operations.

Our future profitability depends, to a significant extent, upon revenue we receive from our middle market business customers and their ability to meet their loan obligations .    Our future profitability depends, to a significant extent, upon revenue we receive from middle market business customers, and their ability to continue to meet existing loan obligations. As a result, adverse economic conditions or other factors adversely affecting this market segment may have a greater adverse effect on us than on other financial institutions that have a more diversified customer base.

System failure or breaches of our network security could subject us to increased operating costs as well as litigation and other liabilities .    The computer systems and network infrastructure we use could be vulnerable to unforeseen problems. Our operations are dependent upon our ability to protect our computer equipment against damage from fire, power loss, telecommunications failure or a similar catastrophic event and our reliance on third party service providers who provide many of our technology services. Any damage or failure that causes an interruption in our operations could have an adverse effect on our customers. In addition, we must be able to protect the computer systems and network infrastructure utilized by us against physical damage, security breaches and service disruption caused by the Internet or other users. Such

14

Table of Contents

computer break-ins and other disruptions would jeopardize the security of information stored in and transmitted through our computer systems and network infrastructure, which may result in significant liability to us and deter potential customers. Although we, with the help of third-party service providers, will continue to implement security technology and establish operational procedures to prevent such damage, there can be no assurance that these security measures will be successful. In addition, the failure of our customers to maintain appropriate security for their systems may increase our risk of loss. We have and will continue to incur costs with the training of our customers about protection of their systems. However, we cannot be assured that this training will be adequate to avoid risk to our customers or, under unknown circumstances to us. Cyber threats and other fraud committed against our customers by third parties can result in financial losses to us and expose us to reputation risks that would limit our ability to retain customers.

We are subject to extensive government regulation and supervision .    We are subject to extensive federal and state regulation and supervision. Banking regulations are primarily intended to protect depositors’ funds, federal deposit insurance funds and the banking system as a whole, not shareholders or debtholders. Federal regulation is also designed to cause the banking system to support governmental policies that may not be beneficial to our bank. These regulations affect our lending practices, capital structure, investment practices, accounting, financial reporting, dividend policy, operations and growth, among other things. These regulations also impose obligations to maintain appropriate policies, procedures and controls, among other things, to detect, prevent and report money laundering and terrorist financing and to verify the identities of our customers. Congress and federal regulatory agencies continually review banking laws, regulations and policies for possible changes. Changes to statutes, regulations or regulatory policies, including changes in interpretation or implementation of statutes, regulations or policies, could affect us in substantial and unpredictable ways. The changes in regulation and requirements imposed on financial institutions, such as the Dodd-Frank Act and Basel III accord, could subject us to additional costs, impose requirements for additional capital, limit the types of financial services and products we may offer and/or increase the ability of non-banks to offer competing financial services and products, among other things. Over a year after the adoption of the Dodd-Frank Act, there are still many related regulations that have not been written, so the effects of those are unknown at this time. In addition, from time to time we receive inquiries from our regulators regarding, among other things, lending practices, reserve methodology, interest rate and operational risk management, regulatory and financial accounting practices and policies and related matters. Additionally, we will be subject to stress testing requirements, and the inability to know what conditions or risk factors will be imposed could subject us to criticism from regulators. Any change to our practices or policies requested or required by our regulators, or any changes in interpretation of regulatory policy applicable to our businesses, may have a material adverse effect on our business, results of operations, financial condition, credit quality or regulatory capital.

We expend substantial effort and incur costs to improve our systems, controls, accounting, operations, information security, compliance, audit capabilities, stress testing requirements, staffing and training in order to satisfy regulatory requirements, but the regulatory authorities may determine that such efforts are insufficient. Failure to comply with relevant laws, regulations or policies could result in sanctions by regulatory agencies, civil money penalties and/or reputation damage, which could have a material adverse effect on our business, financial condition and results of operations. While we have policies and procedures designed to prevent any such violations, there can be no assurance that such violations will not occur. In addition, the FDIC has imposed higher general and special assessments on deposits based on general industry conditions and as a result of changes in specific programs, and there is no restriction on the amount by which the FDIC may increase deposit assessments in the future. Any increase in FDIC assessments could affect our earnings to a significant degree, and the industry may be subject to additional assessments, fees or taxes.

Furthermore, Sarbanes-Oxley, and the related rules and regulations promulgated by the SEC and Financial Industry Regulatory Authority (“FINRA”) that are applicable to us, have increased the scope, complexity and cost of corporate governance, reporting and disclosure practices. As reports from the Public Company Accounting Oversight Board’s (“PCAOB”) inspections of public accounting firms continue to outline findings and recommendations which could require these firms to perform additional work as part of their financial statement audits, our costs to respond to these added requirements and exposure to adverse findings by the

15

Table of Contents

PCAOB of the work performed may increase. As a result, we have experienced, and may continue to experience, greater compliance and audit costs, as well as additional staffing costs to comply with these changes.

Severe weather, natural disasters, acts of war or terrorism and other external events could significantly impact our business .    Severe weather, natural disasters, acts of war or terrorism and other adverse external events could have a significant impact on our ability to conduct business. Such events could affect the stability of our deposit base, impair the ability of borrowers to repay outstanding loans, impair the value of collateral securing loans, cause significant property damage, result in loss of revenue and/or cause us to incur additional expenses. Periodically, hurricanes have caused extensive flooding and destruction along the coastal areas of Texas, including communities where we conduct business, and our operations in Houston have been disrupted to a minor degree. While the impact of these hurricanes did not significantly affect us, other severe weather or natural disasters, acts of war or terrorism or other adverse external events may occur in the future. Although management has established disaster recovery policies and procedures, the occurrence of any such event could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition and results of operations.

Our management maintains significant control over us .    Our current executive officers and directors beneficially own approximately 4% of the outstanding shares of our common stock. Accordingly, our current executive officers and directors are able to influence, to a significant extent, the outcome of all matters required to be submitted to our stockholders for approval (including decisions relating to the election of directors) and other significant corporate matters.

There are substantial regulatory limitations on changes of control .    With certain limited exceptions, federal regulations prohibit a person or company or a group of persons deemed to be “acting in concert” from, directly or indirectly, acquiring more than 10% (5% if the acquirer is a bank holding company) of any class of our voting stock or obtaining the ability to control in any manner the election of a majority of our directors or otherwise direct the management or policies of our company without prior notice or application to and the approval of the Federal Reserve. Accordingly, prospective investors need to be aware of and comply with these requirements, if applicable, in connection with any purchase of shares of our common stock.

Anti-takeover provisions of our certificate of incorporation, bylaws and Delaware law may make it more difficult for you to receive a change in control premium .    Certain provisions of our certificate of incorporation and bylaws could make a merger, tender offer or proxy contest more difficult, even if such events were perceived by many of our stockholders as beneficial to their interests. These provisions include advance notice for nominations of directors and stockholders’ proposals, and authority to issue “blank check” preferred stock with such designations, rights and preferences as may be determined from time to time by our board of directors. In addition, as a Delaware corporation, we are subject to Section 203 of the Delaware General Corporation Law which, in general, prevents an interested stockholder, defined generally as a person owning 15% or more of a corporation’s outstanding voting stock, from engaging in a business combination with our company for three years following the date that person became an interested stockholder unless certain specified conditions are satisfied.

We are subject to contract claims and litigation pertaining to lending activities, employment practices, fiduciary responsibility related to our wealth management services and other general business matters .    From time to time, customers make claims and take legal action pertaining to our performance of any of the above. Whether customer claims and legal action related to our performance are founded or unfounded, if such claims and legal actions are not resolved in a manner favorable to us they may result in significant financial liability which could require us to increase capital and/or adversely affect the market perception of us and our products and services as well as impact customer demand for those products and services. In addition, employees can make claims related to our employment practices. If such claims or legal actions are not resolved in a manner favorable to us they may result in significant financial liability and/or adversely affect the market perception of us. Any financial liability or reputation damage could have a material adverse effect on our business, which, in turn, could have a material adverse effect on our financial condition and results of operations.

16

Table of Contents

Our controls and procedures may fail or be circumvented .    Management regularly reviews and updates our internal controls, disclosure controls and procedures, and corporate governance policies and procedures. Any system of controls, however well designed and operated, is based in part on certain assumptions and can provide only reasonable, not absolute, assurances that the objectives of the system are met. Any failure or circumvention of our controls and procedures or failure to comply with regulations related to controls and procedures could have a material adverse effect on our business, results of operations and financial condition.

New lines of business or new products and services may subject us to additional risks .    From time to time, we may develop and grow new lines of business or offer new products and services within existing lines of business. There are substantial risks and uncertainties associated with these efforts, particularly in instances where the markets are not fully developed. In developing and marketing new lines of business and/or new products and services we may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved and price and profitability targets may not prove feasible. External factors, such as compliance with regulations, competitive alternatives and shifting market preferences, may also impact the successful implementation of a new line of business or a new product or service. Furthermore, any new line of business and/or new product or service could have a significant impact on the effectiveness of our system of internal controls. Failure to successfully manage these risks in the development and implementation of new lines of business or new products or services could have a material adverse effect on our business, results of operations and financial condition. All service offerings, including current offerings and those which may be provided in the future, may become more risky due to changes in economic, competitive and market conditions beyond our control.

Risks Associated With Our Common Stock

Our stock price can be volatile .    Stock price volatility may make it more difficult for you to resell your common stock when you want and at prices you find attractive. Our stock price can fluctuate significantly in response to a variety of factors including, among other things:

General market fluctuations, industry factors and general economic and political conditions and events, such as economic slowdowns or recessions, interest rate changes or credit loss trends, could also cause our stock price to decrease regardless of operating results as evidenced by the current volatility and disruption of capital and credit markets.

The trading volume in our common stock is less than that of other larger financial services companies .    Although our common stock is traded on the Nasdaq Global Select Market, the trading volume in our common stock is less than that of other larger financial services companies. A public trading market having the desired characteristics of depth, liquidity and orderliness depends on the presence in the marketplace of willing

17

Table of Contents

buyers and sellers of our common stock at any given time. This presence depends on the individual decisions of investors and general economic and market conditions over which we have no control. Given the lower trading volume of our common stock, significant sales of our common stock, or the expectation of these sales, could cause our stock price to fall. In addition, a substantial majority of common stock outstanding is held by institutional shareholders, and trading activity involving large positions may increase volatility of the stock price. Concentration of ownership by institutional investors and inability to execute large trades covering large numbers of shares can increase volatility of stock price. Changes in outlook or view of the institutional investors, whether factual or speculative, can have a major impact on stock price.

An investment in our common stock is not an insured deposit. Our common stock is not a bank deposit and, therefore, is not insured against loss by the FDIC, any other deposit insurance fund or by any other public or private entity. Investment in our common stock is inherently risky for the reasons described in this “Risk Factors” section and elsewhere in this report and is subject to the same market forces that affect the price of common stock in any company. As a result, if you acquire our common stock, you may lose some or all of your investment.

The holders of our subordinated notes have rights that are senior to those of our shareholders. As of December 31, 2012, we had $111.0 million in subordinated notes outstanding that were issued in a public offering. Our subordinated notes are senior to our shares of common stock. As a result, we must make payments on our subordinated notes before any dividends can be paid on our common stock and, in the event of our bankruptcy, dissolution or liquidation, the holders of the debentures must be satisfied before any distributions can be made to our shareholders.

The holders of our junior subordinated debentures have rights that are senior to those of our shareholders .    As of December 31, 2012 we had $113.4 million in junior subordinated debentures outstanding that were issued to our statutory trusts. The trusts purchased the junior subordinated debentures from us using the proceeds from the sale of trust preferred securities to third party investors. Payments of the principal and interest on the trust preferred securities are conditionally guaranteed by us to the extent not paid or made by each trust, provided the trust has funds available for such obligations.

Our junior subordinated debentures are senior to our shares of common stock. As a result, we must make payments on our junior subordinated debentures (and the related trust preferred securities) before any dividends can be paid on our common stock and, in the event of our bankruptcy, dissolution or liquidation, the holders of the debentures must be satisfied before any distributions can be made to our shareholders. If certain conditions are met, we have the right to defer interest payments on the junior subordinated debentures (and the related trust preferred securities) at any time or from time to time for a period not to exceed 20 consecutive quarters in a deferral period, during which time no dividends may be paid to holders of our common stock.

We do not currently pay dividends .    Our ability to pay dividends is limited and we may be unable to pay future dividends. We do not currently pay dividends on our common stock. Our ability to pay dividends is limited by regulatory restrictions and the need to maintain sufficient consolidated capital. The ability of our bank subsidiary, Texas Capital Bank, to pay dividends to us is limited by its obligations to maintain sufficient capital and by other general restrictions on its dividends that are applicable to our regulated bank subsidiary. If these regulatory requirements are not met, our subsidiary bank will not be able to pay dividends to us, and we could be unable to pay dividends on our common stock or meet debt or other contractual obligations.

Risks Associated With Our Industry

The earnings of financial services companies are significantly affected by general business and economic conditions .    As a financial services company, our operations and profitability are impacted by general business and economic conditions in the United States and abroad. These conditions include short-term and long-term interest rates, inflation, money supply, economic conditions in foreign markets, political issues, legislative and regulatory changes, fluctuation in both debt and equity capital markets, broad trends in industry and finance and the strength of the U.S. economy and the local economies in which we operate, all of which are

18

Table of Contents

beyond our control. Continued weakness or further deterioration in economic conditions could result in decreases in loan collateral values and increases in loan delinquencies, non-performing assets and losses on loans and other real estate acquired through foreclosure of loans. Industry conditions, competition and the performance of our bank could also result in a decrease in demand for our products and services, among other things, any of which could have a material adverse impact on our results of operations and financial condition.

There can be no assurance that recent and future legislation will not subject us to heightened regulation, and the impact of such legislation on us cannot be reliably determined at this time .    On July 21, 2010, President Obama signed into law the Dodd-Frank Act, which imposes significant regulatory and compliance changes. The changes resulting from the Dodd-Frank Act may impact the profitability of our business activities, require changes to certain of our business practices, impose upon us more stringent capital, liquidity and leverage requirements or otherwise adversely affect our business. These changes may also require us to invest significant management attention and resources to evaluate and make any changes necessary to comply with the new statutory and regulatory requirements. Failure to comply with the new requirements or with any future changes in laws, regulations or interpretations of policy may negatively impact our results of operations, financial condition, operating results and capital adequacy. We cannot predict what additional legislation may be enacted affecting banks and bank holding companies and their operations, or what regulations might be adopted by bank regulators or the effects thereof. In light of current economic conditions in the financial markets and the United States economy, Congress and regulators have increased their focus on the regulation of the banking industry. If enacted, any new legislative or regulatory initiatives could affect us in substantial and unpredictable ways, including increased compliance costs and additional operating restrictions on our business, and could result in an adverse effect on our business, financial condition and results of operations.

Financial services companies depend on the accuracy and completeness of information about customers and counterparties .    In deciding whether to extend credit or enter into other transactions, we may rely on information furnished by or on behalf of customers and counterparties, including financial statements, credit reports and other financial information. We may also rely on representations of those customers, counterparties or other third parties, such as independent auditors, as to the accuracy and completeness of that information. Reliance on inaccurate or misleading financial statements, credit reports or other financial information could have a material adverse impact on our business and, in turn, our results of operations and financial condition.

We compete in an industry that continually experiences technological change, and we may have fewer resources than many of our competitors to continue to invest in technological improvements .    The financial services industry is undergoing rapid technological changes, with frequent introductions of new technology-driven products and services which our customers may require. Many of our competitors have substantially greater resources to invest in technological improvements. We may not be able to effectively implement new technology-driven products and services or be successful in marketing these products and services to our customers. Our growth and changes in regulation may cause services and applications provided by vendors to be obsolete and unable to meet our business requirements, competitive needs or requirements imposed upon us by regulatory authorities. Failure to meet business, competitive and regulatory requirements could cause us to suffer additional risks or costs necessary to address those risks.

Consumers and businesses may decide not to use banks to complete their financial transactions. Technology and other changes are allowing parties to complete financial transactions that historically have involved banks through alternative methods. The possibility of eliminating banks as intermediaries could result in the loss of interest and fee income, as well as the loss of customer deposits and the related income generated from those deposits. The loss of these revenue streams and the lower cost deposits as a source of funds could have a material adverse effect on our results of operations and financial condition.

As of December 31, 2012, we conducted business at thirteen full service banking locations and one operations center. Our operations center houses our loan and deposit operations and the customer service call center. We lease the space in which our banking centers and the operations call center are located. These leases expire between March 2013 and May 2024, not including any renewal options that may be available.

In the fourth quarter of 2012, we recorded a $4.0 million pre-tax charge related to the settlement of a $65.4 million jury verdict that was rendered in August 2011, in rural southeastern Oklahoma. As noted in prior filings, we have attempted to overturn this verdict on post-trial motions and appeal. The case was filed in May 2010 by one of the guarantors of a defaulted loan to an auto dealership in Hugo, Oklahoma, after we already had filed suit in Texas against the debtor and the three co-guarantors to recover the debt, and despite a forum selection clause in the guaranty requiring that any lawsuits be brought in Texas. The guarantor conceded he had signed the guaranty and that the guaranty was valid, but complained that he later had been defrauded because we had failed to notify him about on-going fraud at the dealership. Although he lacked much arguable economic loss, if any, the guarantor repeatedly emphasized to the jury in the Oklahoma case that we were claiming about $6.7 million, plus accumulating interest, on the debt and guaranty in the Texas lawsuit, and that we were asking for those damages to be trebled because of RICO violations. The Oklahoma jury proceeded to award the guarantor a total of $21.8 million in money damages, which was almost exactly three times his estimated prospective liability on his guaranty, and went on to award twice that amount in punitive damages.

In addition to seeking to overturn the Oklahoma jury verdict, we continued to pursue the Texas lawsuit over the guaranty, and in April 2012, we received summary judgment ordering the guarantor to pay us approximately $7 million on the debt. In reaction to these post-trial developments, the guarantor re-asserted the same claims that were the basis for his Oklahoma judgment as counterclaims in the Texas action. We moved for summary judgment against the guarantor on these claims and the guarantor then dismissed those claims with prejudice. We obtained a final judgment on the guaranty and the counterclaims in Texas, and in the fourth quarter of 2012 we moved to dismiss the case and vacate the verdict in Oklahoma on the ground that the final Texas judgment had preclusive effect under the Full Faith and Credit Clause of the U.S. Constitution.

The Oklahoma court ordered a settlement conference, but in advance of that conference the parties conducted a private mediation in December 2012. We reached a confidential settlement under which all litigation against us in the Oklahoma courts and actions by us against the plaintiff in the Texas courts will be dismissed with prejudice. The settlement amount was within policy limits of insurance coverage maintained by the Company, and we are aggressively pursuing claims against the insurance company for more than the pre-tax charge.

Our common stock is traded on The Nasdaq Global Select Market under the symbol “TCBI”. On February 19, 2013, there were approximately 257 holders of record of our common stock.

No cash dividends have ever been paid by us on our common stock, and we do not anticipate paying any cash dividends in the foreseeable future. Our principal source of funds to pay cash dividends on our common stock would be cash dividends from our bank. The payment of dividends by our bank is subject to certain restrictions imposed by federal and state banking laws, regulations and authorities.

Overview of Our Business Operations

We commenced our banking operations in December 1998. An important aspect of our growth strategy has been our ability to service and effectively manage a large number of loans and deposit accounts in multiple markets in Texas. Accordingly, we created an operations infrastructure sufficient to support state-wide lending and banking operations.

The following discussions and analyses present the significant factors affecting our financial condition as of December 31, 2012 and 2011 and results of operations for each of the three years in the period ended December 31, 2012. This discussion should be read in conjunction with our consolidated financial

statements and notes to the financial statements appearing later in this report. Please also note the below description about our discontinued operations and how it is reflected in the following discussions of our financial condition and results of operations.

On October 16, 2006, we completed the sale of our residential mortgage lending division (“RML”). The sale was effective as of September 30, 2006, and, accordingly, all operating results for this discontinued component of our operations were reclassified to discontinued operations. All prior periods were restated to reflect the change. Subsequent to the end of the first quarter of 2007, Texas Capital Bank and the purchaser of its residential mortgage loan division (RML) agreed to terminate and settle the contractual arrangements related to the sale of the division.

The loss from discontinued operations was $37,000 and $126,000, net of taxes, for the years ended December 31, 2012 and 2011, respectively. The 2012 and 2011 losses are primarily related to continuing legal expenses incurred in dealing with the remaining loans and requests from investors related to the repurchase of previously sold loans. We still have approximately $302,000 in loans held for sale from discontinued operations that are carried at the estimated market value at year-end, which is less than the original cost. We plan to sell these loans, but timing and price to be realized cannot be determined at this time due to market conditions. In addition, we will address any future requests from investors related to repurchasing loans previously sold. While the balances as of December 31, 2012 and 2011 include a liability for exposure to additional contingencies, including risk of having to repurchase loans previously sold, we recognize that market conditions may result in additional exposure to loss and the extension of time necessary to complete the discontinued mortgage operation. Our mortgage warehouse lending operations were not part of the sale, and are included in the results from continuing operations. Except as otherwise noted, all amounts and disclosures throughout this document reflect only the Company’s continuing operations.

Year ended December 31, 2012 compared to year ended December 31, 2011

We reported net income of $120.7 million, or $3.01 per diluted common share, for the year ended December 31, 2012, compared to $76.1 million, or $1.99 per diluted common share, for the same period in 2011. Return on average equity was 16.93% and return on average assets was 1.35% for the year ended December 31, 2012, compared to 13.39% and 1.12%, respectively, for the same period in 2011.

Net income increased $44.6 million, or 59%, for the year ended December 31, 2012 compared to the same period in 2011. The $44.6 million increase was primarily the result of a $73.9 million increase in net interest income, a $17.0 million decrease in the provision for credit losses and a $10.8 million increase in non-interest income, offset by a $31.6 million increase in non-interest expense, and a $25.5 million increase in income tax expense.

Details of the changes in the various components of net income are further discussed below.

Year ended December 31, 2011 compared to year ended December 31, 2010

We reported net income of $76.1 million, or $1.99 per diluted common share, for the year ended December 31, 2011, compared to $37.3 million, or $1.00 per diluted common share, for the same period in 2010. Return on average equity was 13.39% and return on average assets was 1.12% for the year ended December 31, 2011, compared to 7.23% and .63%, respectively, for the same period in 2010.

Net income increased $38.8 million, or 104%, for the year ended December 31, 2011 compared to the same period in 2010. The $38.8 million increase was primarily the result of a $61.3 million increase in net interest income and a $25.0 million decrease in the provision for credit losses, offset by a $24.7 million increase in non-interest expense and a $22.7 million increase in income tax expense.

Details of the changes in the various components of net income are further discussed below.

Net Interest Income

The average cost of interest bearing liabilities decreased from 0.40% for the year ended December 31, 2011 to 0.35% in 2012, reflecting the continued low market interest rates, and our focus on reducing deposit rates.

Net interest income was $302.9 million for the year ended December 31, 2011 compared to $241.7 million for the same period of 2010. The increase in net interest income was primarily due to an increase of $819.4 million in average earning assets and the increase in our net interest margin. The increase in average earning assets from 2010 included a $915.4 million increase in average net loans offset by a $65.6 million decrease in average securities. For the year ended December 31, 2011, average net loans and securities represented 96% and 2%, respectively, of average earning assets compared to 93% and 4%, respectively, in 2010.

Average interest bearing liabilities for the year ended December 31, 2011 increased $393.7 million from the year ended December 31, 2010, which included a $48.5 million decrease in interest bearing deposits and a $442.3 million increase in other borrowings. At the beginning of the year we actively turned away certain higher priced deposits. For the same periods, the average balance of demand deposits increased to $1.5 billion from $1.1 billion. The average cost of interest bearing liabilities decreased from 0.89% for the year ended December 31, 2010 to 0.40% in 2011, reflecting the continued low market interest rates, and our focus on reducing deposit rates.
