(vi) the quality and composition of our securities portfolio; (vii) changes in general economic conditions, either nationally or in our market areas, including the impact of supply chain disruptions, or changes in financial markets, and the risk of recession; (viii) changes in the interest rate environment and levels of general interest rates, including the recent and anticipated increases by the FRB in its benchmark rate, the impacts of inflation, the relative differences between short- and long-term interest rates, deposit interest rates, our net interest margin, and funding sources;

(xii) legislative or regulatory changes that adversely affect our business, including, without limitation, changes in tax laws and policies, changes in privacy laws, and changes in regulatory capital or other rules, and the availability of resources to address or respond to such changes;

(xxv) continuing impact of the Financial Accounting Standards Board’s credit loss accounting standard, referred to as Current Expected Credit Loss, which requires financial institutions to determine periodic estimates of lifetime expected credit losses on loans, and provide for the expected credit losses as allowances for loan losses; (xxvi) share price volatility and reputational risks, related to, among other things, speculative trading and certain traders shorting our common shares and attempting to generate negative publicity about us;

27 NON-GAAP FINANCIAL INFORMATION This presentation contains certain financial measures determined by methods other than in accordance with U.S. generally accepted accounting principles (GAAP). These measures include tangible assets, tangible equity, tangible common equity, tangible equity to tangible assets, tangible common equity to tangible assets, tangible common equity per share, return on average tangible common equity, adjusted noninterest expense, adjusted noninterest expense to average total assets, pre-tax pre-provision (PTPP) income (loss), adjusted PTPP income (loss), PTPP income (loss) ROAA, adjusted PTPP income (loss) ROAA, efficiency ratio, adjusted efficiency ratio, adjusted net income, adjusted net income available to common stockholders, adjusted diluted earnings per share (EPS) and adjusted return on average assets (ROAA) constitute supplemental financial information determined by methods other than in accordance with GAAP. These non-GAAP measures are used by management in its analysis of the Company's performance. Tangible assets and tangible equity are calculated by subtracting goodwill and other intangible assets from total assets and total equity. Tangible common equity is calculated by subtracting preferred stock from tangible equity. Return on average tangible common equity is computed by dividing net income (loss) available to common stockholders, after adjustment for amortization of intangible assets, by average tangible common equity. Banking regulators also exclude goodwill and other intangible assets from stockholders' equity when assessing the capital adequacy of a financial institution. PTPP income is calculated by adding net interest income and noninterest income (total revenue) and subtracting noninterest expense. Adjusted PTPP income is calculated by adding total revenue and subtracting adjusted noninterest expense. PTPP income ROAA is computed by dividing annualized PTPP income by average assets. Adjusted PTPP income ROAA is computed by dividing annualized adjusted PTPP income by average assets. Efficiency ratio is computed by dividing noninterest expense by total revenue. Adjusted efficiency ratio is computed by dividing adjusted noninterest expense by total revenue. Adjusted net income (loss) is calculated by adjusting net income (loss) for tax- effected noninterest expense adjustments and the tax impact from the exercise of stock appreciation rights for the periods indicated. Adjusted ROAA is computed by dividing annualized adjusted net income by average assets. Adjusted net income (loss) available to common stockholders is computed by removing the impact of preferred stock redemptions from adjusted net income (loss). Adjusted diluted earnings per share is computed by dividing adjusted net income (loss) available to common stockholders by the weighted average diluted common shares outstanding. Management believes the presentation of these financial measures adjusting the impact of these items provides useful supplemental information that is essential to a proper understanding of the financial results and operating performance of the Company. This disclosure should not be viewed as a substitute for results determined in accordance with GAAP, nor is it necessarily comparable to non-GAAP performance measures that may be presented by other companies. Reconciliations of these measures to measures determined in accordance with GAAP are contained on slides 28-32 of this presentation.
