Forward Looking Statements 2 Certain statements in this presentation may constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking statements are statements that include, projections, predictions, expectations, or beliefs about future events or results that are not statements of historical fact. Such forward-looking statements are based on various assumptions as of the time they are made, and are inherently subject to known and unknown risks, uncertainties, and other factors, some of which cannot be predicted or quantified, that may cause actual results, performance, or achievements to be materially different from those expressed or implied by such forward-looking statements. Forward-looking statements are often accompanied by words that convey projected future events or outcomes such as “expect,” “believe,” “estimate,” “plan,” “project,” “anticipate,” “intend,” “will,” “may,” “view,” “opportunity,” “potential,” or words of similar meaning or other statements concerning opinions or judgment of the Company and its management about future events. Although the Company believes that its expectations with respect to forward-looking statements are based upon reasonable assumptions within the bounds of its existing knowledge of its business and operations, there can be no assurance that actual results, performance, or achievements of, or trends affecting, the Company will not differ materially from any projected future results, performance, or achievements expressed or implied by such forward-looking statements. Actual future results, performance, achievements or trends may differ materially from historical results or those anticipated depending on a variety of factors, including, but not limited to the effects of or changes in: • changes in interest rates; • general economic and financial market conditions, in the United States generally and particularly in the markets in which the Company operates and which its loans are concentrated, including the effects of declines in real estate values, an increase in unemployment levels and slowdowns in economic growth, including as a result of COVID-19; • the quality or composition of the loan or investment portfolios and changes therein; • demand for loan products and financial services in the Company’s market area; • the Company’s ability to manage its growth or implement its growth strategy; • the effectiveness of expense reduction plans; • the introduction of new lines of business or new products and services; • the Company’s ability to recruit and retain key employees; • the incremental cost and/or decreased revenues associated with exceeding $10 billion in assets; • real estate values in the Bank’s lending area; • an insufficient ACL; • changes in accounting principles; • the Company’s liquidity and capital positions; • concentrations of loans secured by real estate, particularly commercial real estate; • the effectiveness of the Company’s credit processes and management of the Company’s credit risk; • the Company’s ability to compete in the market for financial services and increased competition from fintech companies; • technological risks and developments, and cyber threats, attacks, or events; • the potential adverse effects of unusual and infrequently occurring events, such as weather- related disasters, terrorist acts or public health events (such as COVID-19), and of governmental and societal responses thereto; these potential adverse effects may include, without limitation, adverse effects on the ability of the Company's borrowers to satisfy their obligations to the Company, on the value of collateral securing loans, on the demand for the Company's loans or its other products and services, on supply chains and methods used to distribute products and services, on incidents of cyberattack and fraud, on the Company’s liquidity or capital positions, on risks posed by reliance on third-party service providers, on other aspects of the Company's business operations and on financial markets and economic growth; • the effect of steps the Company takes in response to COVID-19, the severity and duration of the pandemic, the uncertainty regarding new variants of COVID-19 that have emerged, the speed and efficacy of vaccine and treatment developments, the impact of loosening or tightening of government restrictions, the pace of recovery when the pandemic subsides and the heightened impact it has on many of the risks described herein; • the discontinuation of LIBOR and its impact on the financial markets, and the Company’s ability to manage operational, legal and compliance risks related to the discontinuation of LIBOR and implementation of one or more alternate reference rates, • performance by the Company’s counterparties or vendors; • deposit flows; • the availability of financing and the terms thereof; • the level of prepayments on loans and mortgage-backed securities; • legislative or regulatory changes and requirements, including the impact of the CARES Act, as amended by the CAA, and other legislative and regulatory reactions to COVID-19; • potential claims, damages, and fines related to litigation or government actions, including litigation or actions arising from the Company’s participation in and administration of programs related to COVID-19, including, among other things, the CARES Act, as amended by the CAA; • the effects of changes in federal, state or local tax laws and regulations; • monetary and fiscal policies of the U.S. government, including policies of the U.S. Department of the Treasury and the Federal Reserve; • changes to applicable accounting principles and guidelines; and • other factors, many of which are beyond the control of the Company.

Reconciliation of Non-GAAP Disclosures 19 Operating Earnings Per Share The Company has provided supplemental performance measures on a tax-equivalent, tangible, operating, adjusted, or pre-tax pre-provision basis. These non-GAAP financial measures are supplements to GAAP, which is used to prepare the Company’s financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, the Company’s non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. The Company uses the non-GAAP financial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure trends in the Company’s underlying performance.

Reconciliation of Non-GAAP Disclosures 20 Operating Earnings Per Share Adjusted operating measures exclude the gains or losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment) and gains or losses on sale of securities. The Company believes these non-GAAP adjusted measures provide investors with important information about the combined economic results of the organization’s operations. The adjusted operating efficiency ratio (FTE) excludes the amortization of intangible assets and gains or losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment). This measure is similar to the measure utilized by the Company when analyzing corporate performance and is also similar to the measure utilized for incentive compensation. The Company believes this adjusted measure provides investors with important information about the combined economic results of the organization’s operations.

Reconciliation of Non-GAAP Disclosures 21 Operating Earnings Per Share Net interest income (FTE) and total adjusted revenue (FTE), which are used in computing net interest margin (FTE) and adjusted operating efficiency ratio (FTE), respectively, provide valuable additional insight into the net interest margin and the efficiency ratio by adjusting for differences in tax treatment of interest income sources.

Reconciliation of Non-GAAP Disclosures 22 Tangible assets, tangible common equity, and leverage ratio are used in the calculation of certain profitability, capital, and per share ratios. The Company believes tangible assets, tangible common equity, leverage ratio, and the related ratios are meaningful measures of capital adequacy because they provide a meaningful base for period-to-period and company-to-company comparisons, which the Company believes will assist investors in assessing the capital of the Company and its ability to absorb potential losses.

Reconciliation of Non-GAAP Disclosures 23 Operating Earnings Per Share The Company believes that return on tangible common equity (ROTCE) is a meaningful supplement to GAAP financial measures and useful to investors because it measures the performance of a business consistently across time without regard to whether components of the business were acquired or developed internally. Adjusted operating measures exclude the gains or losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment) and gains or losses on sale of securities. The Company believes these non-GAAP adjusted measures provide investors with important information about the combined economic results of the organization’s operations.

Reconciliation of Non-GAAP Disclosures 25 ($ IN THOUSANDS) Operating Earnings Per Share PPP adjustment impact excludes the SBA guaranteed loans funded during 2020 and 2021. The Company believes loans held for investment (net of deferred fees and costs), excluding PPP is useful to investors as it provides more clarity on the Company’s organic growth. The Company also believes that the related non-GAAP financial measures of past due loans still accruing interest as a percentage of total loans held for investment (net of deferred fees and costs), excluding PPP, are useful to investors as loans originated under the PPP carry an SBA guarantee. The Company believes that the ALLL as a percentage of loans held for investment (net of deferred fees and costs), excluding PPP, is useful to investors because of the size of the Company’s PPP originations and the impact of the embedded credit enhancement provided by the SBA guarantee.
