3 LEGAL DISCLOSURES Special Note Concerning Forward-Looking Statements This investor presentation contains “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995. All statements other than statements of historical fact are forward-looking statements. You can identify these forward-looking statements in some cases through the Company’s use of words such as “believes,” “anticipates,” “expects,” “may,” “will,” “assumes,” “should,” “predicts,” “could,” “would,” “intends,” “targets,” “estimates,” “projects,” “plans,” “potential” and other similar words and expressions of the future or otherwise regarding the Company’s future business and financial performance and/or the performance of the banking and mortgage industry and economy in general. Forward-looking statements are based on the information known to, and current beliefs and expectations of, the Company’s management and are subject to significant risks and uncertainties. Actual results may differ materially from those contemplated by such forward-looking statements. A number of important factors could cause actual results to differ materially from those contemplated by the forward-looking statements in this presentation including, without limitation, the risks set forth in “Forward Looking Statements” and “Risk Factors” in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the SEC on March 1, 2024 (as may be amended in the Company’s Quarterly Reports on Form 10-Q). Many of these factors are difficult to foresee and are beyond the Company’s ability to control or predict. The Company believes the forward-looking statements contained herein are reasonable; however, undue reliance should not be placed on any forward-looking statements, which are based on current expectations and speak only as of the date that they are made. The Company does not assume any obligation to update any forward-looking statements as a result of new information, future developments or otherwise, except as otherwise may be required by law. Non-GAAP Financial Measures This presentation includes certain financial measures that are not measures recognized under U.S. generally accepted accounting principles (“GAAP”) and therefore are considered non-GAAP financial measures. The Company’s management uses these non-GAAP financial measures in their analysis of the Company’s performance, financial condition and the efficiency of its operations. Management believes that these non-GAAP financial measures provide a greater understanding of the ongoing operations and enhance comparability of results with prior periods. The Company’s management also believes that investors find these non-GAAP financial measures useful as they assist investors in understanding the Company’s underlying operating performance and the analysis of ongoing operating trends. However, the non-GAAP financial measures discussed herein should not be considered in isolation or as a substitute for the most directly comparable or other financial measures calculated in accordance with GAAP. Moreover, the manner in which the Company calculates the non-GAAP financial measures discussed herein may differ from the reporting measures with similar names as used by other companies. You should understand how such other banking organizations calculate their non-GAAP financial measures with names similar to the non-GAAP financial measures discussed herein when comparing such information. Reconciliations of non-GAAP financial measures to GAAP financial measures are provided in the Appendix to this presentation.

HFS) / Deposits 92.80 % 91.32 % 97.69 % Year-over-year shift was due to focus on organic deposit growth. Borrowings decreased $1.8 million for the quarter. The year-over- year decline of $365.7 million was mostly due to the payoff of a $300.0 million BTFP advance in March as well as paydowns of FHLB advances of $57.0 million. Increase in equity for the quarter was driven by $15.9 million net income available to common shareholders as well as a $3.9 million improvement in AOCI for Q2. The annual increase was driven by $61.7 million net income available to common shareholders as well as a $13.5 million AOCI improvement. Highlights Improvement for the quarter and year are due to retention of earnings coupled with a positive AOCI changes. TBV improved from the linked quarter and is attributed to $15.9 million net income available to common shareholders and a $3.9 million improvement in AOCI. TBVPS growth excluding AOCI of 8.64% QTD and 8.97% year-over-year show franchise value. The improvement in the risk-based capital ratio was attributable to retained earnings supporting loan growth. Actual Change vs. Q2'24 Highlights Organic loan growth of 1.45% for the quarter (5.85% Annualized) led by C&I ($93.4 million) and a reduction in C&D (-$24.6 million) and CRE (-$17.8 million). Year-over-year loan growth ($264.1 million) was headlined by organic growth in DFW, SWLA and Capital regions maintaining our Texas exposure at 36%. Deposits decreased $9.1 million (0.16%, or 0.66% Annualized) during Q2 mostly attributable to $24.2 million contraction in interest-bearing deposits partially offset by $15.2 million growth in noninterest-bearing deposits. The interest-bearing contraction was mostly due to $75.1 million of strategic reductions of brokered deposits. ACL + Fair Value Discount on acquired loans as a percentage of total loans of 1.05%. Loan purchase discount decreased by approximately $1.7 million. The slight quarterly improvement in fair market value was due to positive fair value adjustments ($4.9 million).
