TCBI is headquartered in Dallas, with primary banking offices in Austin, Dallas, Fort Worth, Houston and San Antonio, and has built a network of clients across the country.

(“TCBI Securities”). The Bank is a Texas state-chartered bank. TCBI Securities is a registered broker-dealer with the U.S. Securities and Exchange Commission (“SEC”) and a member of the Financial Industry Regulatory Authority and Municipal Securities Rulemaking Board. The Company was incorporated as a Delaware corporation in 1996 and commenced banking operations in 1998. Basis of Presentation The Company’s accounting and reporting policies conform to accounting principles generally accepted in the United States (“GAAP”) and to generally accepted practices within the banking industry. Certain prior period balances have been reclassified to conform to the current period presentation. The consolidated interim financial statements are unaudited, and certain information and disclosures in the notes to consolidated unaudited financial statements that are presented in accordance with GAAP have been condensed or omitted. In the opinion of management, the interim financial statements include all normal and recurring adjustments and the disclosures made present a fair presentation of the Company’s financial position and results of operations. The consolidated financial statements have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10-Q adopted by the SEC. Accordingly, the financial statements and the notes to the consolidated unaudited financial statements required by GAAP for complete annual financial statements do not include all of the information and should be read in conjunction with the consolidated financial statements, and notes thereto, for the year ended December 31, 2024, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”). Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The allowance for credit losses, the fair value of financial instruments and the status of contingencies are particularly susceptible to significant change.
