2023 Outlook 19 With a Lag, the NIM Should Begin to Rebound After Fed Rate Increases Stop  Loan Growth – Higher rate environment to impact origination volumes and prepayments speeds  Funding – Focused on deposits; borrowings will fill any gaps  Net Interest Income – Expect NIM pressure until Fed stops raising rates – Lag before loan repricing drives NIM expansion  Noninterest Expense – Normalization of accruals – Increase in medical insurance expense – Increase in FDIC Insurance premiums – First quarter seasonality  Effective Tax Rate – Expecting ~24 - 25%

3 4 1 2 Grow Funding Sources Maintain Loan Portfolio  Focus on full relationships across all business units  Emphasize noninterest bearing DDA  Navigate the rate environment  More selective in lending  Focus on risk - adjusted returns  Full relationship lending Focus on Asset Quality Leverage Technology  Will not sacrifice credit quality for growth  No change to risk profile  Maintain conservative underwriting standards  Evaluate new Fintech partnerships  Expand digital lending platform  Continue to drive digital engagement 2023 Strategic Objectives: Navigating Through the Environment 20

Appendix 22

Reconciliation of GAAP Earnings and Core Earnings 23 Non - cash Fair Value Adjustments to GAAP Earnings The variance in GAAP and core earnings is partly driven by the impact of non - cash net gains and losses from fair value adjustments .. These fair value adjustments relate primarily to borrowing carried at fair value under the fair value option and swaps designated to protect against rising rates .. As the swaps get closer to maturity, the volatility in fair value adjustments will dissipate .. In a rising interest rate environment or a steepening of the yield curve, the loss position would experience an improvement .. In a declining interest rate environment, the movement in the curve exaggerates our mark - to - market loss position .. Core Net Income, Core Diluted EPS, Core ROAE, Core ROAA, Pre - provision, Pre - tax Net Revenue, Core Net Interest Income FTE, Core Net Interest Margin FTE, Core Interest Income and Yield on Total Loans, Core Noninterest Income, Core Noninterest Expense and Tangible Book Value per common share are each non - GAAP measures used in this presentation .. A reconciliation to the most directly comparable GAAP financial measures appears below in tabular form .. The Company believes that these measures are useful for both investors and management to understand the effects of certain interest and noninterest items and provide an alternative view of the Company's performance over time and in comparison to the Company's competitors .. These measures should not be viewed as a substitute for net income .. The Company believes that tangible book value per common share is useful for both investors and management as these are measures commonly used by financial institutions, regulators and investors to measure the capital adequacy of financial institutions .. The Company believes these measures facilitate comparison of the quality and composition of the Company's capital over time and in comparison to its competitors .. These measures should not be viewed as a substitute for total shareholders' equity .. These non - GAAP measures have inherent limitations, are not required to be uniformly applied and are not audited .. They should not be considered in isolation or as a substitute for analysis of results reported under GAAP .. These non - GAAP measures may not be comparable to similarly titled measures reported by other companies ..
