Q1 2024 Investor Presentation April 22, 2024

2 Important Notices and Disclaimers Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the federal securities laws, which reflect our current expectations and beliefs with respect to, among other things, future events and our financial performance. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. This may be especially true given recent events and trends in the banking industry and the inflationary environment. Although we believe that the expectations reflected in such forward-looking statements are reasonable as of the dates made, we cannot give any assurance that such expectations will prove correct and actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. Important factors that could cause actual results to differ materially from those in the forward-looking statements are set forth in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, and in other SEC filings under the sections entitled “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors”. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions and uncertainties that are difficult to predict. These statements are often, but not always, made through the use of words or phrases such as “may,” “can,” “should,” “could,” “to be,” “predict,” “potential,” “believe,” “will likely result,” “expect,” “continue,” “will,” “likely,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “target,” “project,” “would” and “outlook,” or the negative version of those words or other similar words or phrases of a future or forward-looking nature. Forward-looking statements appear in a number of places in this presentation and may include statements about business strategy and prospects for growth, operations, ability to pay dividends, competition, regulation and general economic conditions. Non-GAAP Financial Measures In addition to reporting GAAP results, the Company reports non-GAAP financial measures in this presentation and other disclosures. Our management believes that these non-GAAP financial measures and the information they provide are useful to investors since these measures permit investors to view our performance using the same tools that our management uses to evaluate our performance. While we believe that these non- GAAP financial measures are useful in evaluating our performance, this information should be considered as supplemental in nature and not as a substitute for or superior to the related financial information prepared in accordance with GAAP. Additionally, these non-GAAP financial measures may differ from similar measures presented by other companies. For a reconciliation of the non-GAAP measures we use to the most comparable GAAP measures, see the Appendix to this presentation.

14 Near-Term Outlook Loan balances expected to continue to grow at a modest pace Deposit balances expected to grow slightly Net interest income expected to be fairly flat as loans grow, though this will be somewhat offset by net interest margin declines Core noninterest income expected to be consistent with Q1 2024 Core noninterest expense is expected to be fairly consistent with Q1 2024 Credit metrics are currently strong and future provision levels are expected to consider both current and evolving economic conditions, as well as changes in credit Balanced approach to capital deployment with flexibility to support organic loan growth trajectory and cash dividend while evaluating stock repurchases Century Bank closing and conversion anticipated in Q3 2024
