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, 2024, filed with the SEC on March 7, 2025 (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.

(3) Past due and nonaccrual loan amounts exclude purchased impaired loans, even if contractually past due or if the Company does not expect to receive payment in full, as the Company is currently accreting interest income over the expected life of the loans. This was applicable to all periods 12/31/2022, and prior. The guidance and methodology were changed beginning 1/1/2023, due to CECL adoption. QUARTERLY FINANCIAL HIGHLIGHTS • Net interest margin excluding loan discount accretion remained stable through continued pricing discipline with new and renewed loan originations while managing rate reductions on interest-bearing deposits. • Weighted average loan originations continued to hold strong in June at 7.43%, down slightly from 7.58% in December. • The weighted average rate of new interest-bearing non-maturity deposits were 3.06% in June down from 3.86% in December. • Investments in non-interest income revenue initiatives continue to show early signs of success with loan sales, mostly SBA loans, producing income of $781,000 coupled with swap revenue of $808,000 during Q2. • Successfully completed a core processing system conversion for the deposits, loans and general ledger systems to Fidelity Information Systems (FIS) to improve capabilities and efficiencies for future growth. 6/30/2024 9/30/2024 12/31/2024 3/31/2025 6/30/2025 Diluted Earnings per Common Share $0.63 $0.65 $0.51 $0.65 $0.70 ROAA 0.95 % 0.97 % 0.78 % 1.00 % 1.07 % ROACE 10.94 10.76 8.23 10.48 10.87 Net Interest Margin 3.45 3.51 3.61 3.68 3.68 Efficiency Ratio(1) 65.14 63.45 63.91 63.85 62.83 Net Income Available to Common Shareholders in thousands $15,856 $16,492 $15,138 $19,193 $20,753 Core Pre-Tax, Pre-Provision Income(1) in thousands $23,494 $25,281 $33,450 $28,742 $28,516 Core Diluted Earnings Per Common Share(1) $0.64 $0.68 $0.66 $0.65 $0.66 Core ROAA(1) 0.98 % 1.01 % 1.00 % 1.01 % 1.01 % Core ROACE(1) 11.22 11.23 10.58 10.53 10.23 Net Interest Margin excluding loan discount accretion(1) 3.34 3.46 3.56 3.64 3.64 Core Efficiency Ratio(1) 64.50 62.21 63.09 63.35 63.51 Tier 1 Leverage Ratio(2) 9.49 % 9.61 % 9.53 % 9.70 % 9.86 % Total Risk-Based Capital Ratio(2) 12.88 % 12.99 % 12.75 % 13.03 % 13.07 % Tangible Common Equity / Tangible Assets(1) 7.43 % 7.75 % 7.63 % 8.06 % 8.19 % Tangible Book Value Per Share(1) $19.22 $20.60 $19.92 $20.84 $21.61 NPLs / Loans (Excl.

Our Texas exposure represented approximately 40% of the overall loan portfolio. Deposits decreased $38.5 million (0.60%, or 2.39% Annualized) during Q2 mostly attributable to $50.7 million of deposits transferred in the Kaplan branch sale. Excluding these sold deposits results in an increase of $12.1 million or 0.19% (0.76% annualized). ACL + Fair Value Discount on acquired loans as a percentage of total loans of 1.19%. Loan purchase discount decreased by approximately $1.2 million. The $5.9 million increase for the quarter stemmed from positive fair market value adjustments ($6.4 million). Increase for the quarter was driven primarily by the sale of the Kaplan branch causing a $50.7 million reduction of deposits in Q2 on which the bank received an 8% premium on the sale. The gain on sale bolsters capital by $3.4 million while also reducing annual operating costs by approximately $750,000. Borrowings increased $179.0 million for the quarter due to an increase in short-term FHLB advances. These advances were done to bolster liquidity during the core conversion process involving a change in the bank's main correspondent banking relationship. Increase in equity for the quarter of $22.1 million driven by positive quarterly earnings coupled with positive after-tax fair value adjustments. Highlights Increase in equity for the quarter of $22.1 million driven by positive quarterly earnings. TBV increased 77 basis points or 3.70% (14.82% annualized) from the linked quarter and is attributed to $20.8 million net income available to common shareholders. The improvement in the risk-based capital ratio was attributable to the retention of earnings coupled with stability of risk-based assets in 2Q25.
