1 Forward–looking statements Certain statements contained in this Presentation that are not historical in nature may be considered forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. These forward-looking statements include, without limitation, statements regarding the Company’s future plans, results, strategies, and expectations, including expectations around changing economic markets. These statements can generally be identified by the use of the words and phrases “may,” “will,” “should,” “could,” “would,” “goal,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” “target,” “aim,” “predict,” “continue,” “seek,” “project,” and other variations of such words and phrases and similar expressions. These forward-looking statements are not historical facts, and are based upon management's current expectations, estimates, and projections, many of which, by their nature, are inherently uncertain and beyond the Company’s control. The inclusion of these forward-looking statements should not be regarded as a representation by the Company or any other person that such expectations, estimates, and projections will be achieved. Accordingly, the Company cautions shareholders and investors 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. Actual results may prove to be materially different from the results expressed or implied by the forward-looking statements. A number of factors could cause actual results to differ materially from those contemplated by the forward-looking statements including, without limitation, (1) current and future economic conditions, including the effects of inflation, interest rate fluctuations, changes in the economy or global supply chain, supply-demand imbalances affecting local real estate prices, and high unemployment rates in the local or regional economies in which the Company operates and/or the US economy generally, (2) changes in government interest rate policies and its impact on the Company’s business, net interest margin, and mortgage operations, (3) any continuation of the recent turmoil in the banking industry, including the associated impact to the Company and other financial institutions of any regulatory changes or other mitigation efforts taken by government agencies in response, (4) increased competition for deposits, (5) the Company’s ability to effectively manage problem credits, (6) any deterioration in commercial real estate market fundamentals, (7) the Company’s ability to identify potential candidates for, consummate, and achieve synergies from, potential future acquisitions, (8) the Company’s ability to successfully execute its various business strategies, (9) changes in state and federal legislation, regulations or policies applicable to banks and other financial service providers, including legislative developments, (10) the effectiveness of the Company’s cybersecurity controls and procedures to prevent and mitigate attempted intrusions, (11) the Company's dependence on information technology systems of third party service providers and the risk of systems failures, interruptions, or breaches of security, and (12) the impact of natural disasters, pandemics, and/or acts of war or terrorism, (13) events giving rise to international or regional political instability, including the broader impacts of such events on financial markets and/or global macroeconomic environments, and (14) general competitive, economic, political, and market conditions. Further information regarding the Company and factors which could affect the forward-looking statements contained herein can be found in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2022, and in any of the Company’s subsequent filings with the SEC. Many of these factors are beyond the Company’s ability to control or predict. If one or more events related to these or other risks or uncertainties materialize, or if the underlying assumptions prove to be incorrect, actual results may differ materially from the forward-looking statements. Accordingly, shareholders and investors should not place undue reliance on any such forward-looking statements. Any forward-looking statement speaks only as of the date of this Presentation, and the Company undertakes no obligation to publicly update or review any forward-looking statement, whether as a result of new information, future developments or otherwise, except as required by law. New risks and uncertainties may emerge from time to time, and it is not possible for the Company to predict their occurrence or how they will affect the Company. The Company qualifies all forward-looking statements by these cautionary statements.

2 Use of non-GAAP financial measures This Presentation contains certain financial measures that are not measures recognized under U.S. generally accepted accounting principles (“GAAP”) and therefore are considered non-GAAP financial measures. These non-GAAP financial measures may include, without limitation, adjusted net income, adjusted diluted earnings per common share, adjusted and unadjusted pre-tax pre-provision earnings, consolidated and segment core revenue, consolidated and segment core noninterest expense and core noninterest income, consolidated and segment core efficiency ratio (tax equivalent basis), adjusted return on average assets and equity, and adjusted pre-tax pre-provision return on average assets. Each of these non-GAAP metrics excludes certain income and expense items that the Company’s management considers to be non-core/adjusted in nature. The Company refers to these non-GAAP measures as adjusted (or core) measures. Also, the Company presents tangible assets, tangible common equity, tangible book value per common share, tangible common equity to tangible assets, on-balance sheet liquidity to tangible assets, return on average tangible common equity, and adjusted return on average tangible common equity. Each of these non-GAAP metrics excludes the impact of goodwill and other intangibles. 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 as management believes such measures facilitate period-to-period comparisons and provide meaningful indications of its operating performance as they eliminate both gains and charges that management views as non-recurring or not indicative of operating performance. Management believes that these non- GAAP financial measures provide a greater understanding of ongoing operations and enhance comparability of results with prior periods as well as demonstrate the effects of significant non-core gains and charges in the current and 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 in the analysis of ongoing operating trends. In addition, because intangible assets such as goodwill and the other items excluded each vary extensively from company to company, the Company believes that the presentation of this information allows investors to more easily compare the Company’s results to the results of other companies. 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 that of other companies reporting measures with similar names. Investors should understand how such other banking organizations calculate their financial measures with names similar to the non-GAAP financial measures the Company has discussed herein when comparing such non-GAAP financial measures. See the corresponding non-GAAP reconciliation tables below in this Presentation for additional discussion and reconciliation of these measures to the most directly comparable GAAP financial measures.
