Outlook Benefitting from steeper yield curve; positioning for higher rates ‒ Steeper yield curve helps asset repricing and keeps funding pressures low ‒ Starting to extend liability duration to help protect from rising short term rates ‒ Continue to build out Commercial lending portfolio and shorten asset duration ‒ $480 million forward starting swaps on wholesale funding More optimistic about operating environment ‒ Accelerated vaccine roll out to have a positive impact on the economy ‒ Asian franchise to become more active as pandemic recedes; more outreach and community events planned ‒ Using some of the benefit from the steeper yield curve to make investments in the business ‒ Digital enhancements are planned with new offerings and business opportunities • Loan pipelines are solid and should translate to better non-PPP loan growth • Empire synergies are underway; costs savings targets on track; working on revenue enhancements; confident in 20% EPS accretion in 2021 Remain very comfortable with our credit profile On right path to reach through-the-cycle goals: ROA ≥1% and ROE ≥10%       15

Reconciliation of GAAP Earnings and Core Earnings 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 swaps designated to protect against rising rates and borrowing carried at fair value under the fair value option. As the swaps get closer to maturity, the volatility in fair value adjustments will dissipate. In a declining interest rate environment, the movement in the curve exaggerates our mark-to-market loss position. In a rising interest rate environment or a steepening of the yield curve, the loss position would experience an improvement. 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, Base Net Interest Income FTE, Base Net Interest Margin FTE, Core Interest Income and Yield on Total Loans, Base Interest Income and Yield on Total Loans, Core Non-interest Income, Core Non-interest 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 non-interest 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. 19
