Appendix

Non-GAAP Financial Information Tangible assets, tangible equity, tangible common equity, tangible common equity to tangible assets, tangible book value per common share, return on average tangible common equity, adjusted return on average tangible common equity, adjusted noninterest income, adjusted noninterest expense, adjusted noninterest income to adjusted total revenue, adjusted noninterest expense to average total assets, adjusted net earnings (loss) available to common stockholders, adjusted diluted earnings (loss) per diluted common share, adjusted return on average assets (“ROAA”), pre-tax pre-provision, pre-goodwill impairment (“PTPP”) income, and adjusted PTPP income 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 stockholders’ equity. Tangible common equity is calculated by subtracting preferred stock, as applicable, from tangible equity. Return on average tangible common equity is calculated by dividing net earnings available to common stockholders, after adjustment for amortization of intangible assets and goodwill impairment, by average tangible common equity. Adjusted return on average tangible common equity is calculated by dividing adjusted net earnings available to common stockholders, after adjustment for amortization of intangible assets, goodwill impairment, and any unusual one-time items, 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. Adjusted net earnings (loss) is calculated by adjusting net earnings (loss) by unusual, one-time items. ROAA is calculated by dividing annualized net earnings (loss) by average assets. Adjusted ROAA is calculated by dividing annualized adjusted net earnings (loss) by average assets. 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 net interest income and adjusted noninterest income (adjusted total revenue) and subtracting adjusted noninterest expense. 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 27-31 of this presentation. First Quarter 2024 Earnings | 26
