Forward-Looking Statements

4 Non-GAAP Financial Measures The Company's accounting and reporting policies conform to U.S. generally accepted accounting principles ("GAAP") and general practices within the banking industry. As a supplement to GAAP, the Company provides non-GAAP performance results, which the Company believes are useful because they assist investors in assessing the Company's operating performance. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in the appendix to this financial review. The Company presents EPS, the efficiency ratio, return on average common equity, and return on average tangible common equity, net income applicable to common shares, all adjusted for certain notable items. These items include the CECL Day 1 non-purchased credit deteriorated (“non-PCD”) provision expense, Louisville expenses1, merger-related charges associated with completed acquisitions, gain on sale of health savings accounts, property optimization charges, and net securities gains/losses. Management believes excluding these items from EPS, the efficiency ratio, return on average common equity, and return on average tangible common equity may be useful in assessing the Company's underlying operational performance since these transactions do not pertain to its core business operations and their exclusion may facilitate better comparability between periods. Management believes that excluding merger-related charges and the CECL Day 1 non-PCD provision expense from these metrics may be useful to the Company, as well as analysts and investors, since these expenses can vary significantly based on the size, type, and structure of each acquisition. Additionally, management believes excluding these items from these metrics may enhance comparability for peer comparison purposes. The Company presents adjusted noninterest expense, which excludes Louisville expenses1, merger-related charges and property optimization charges, as well as adjusted noninterest income, which excludes the gain on sale of health savings accounts and gains/losses on sales of debt securities. Management believes that excluding these items from noninterest expense and noninterest income may be useful in assessing the Company’s underlying operational performance as these items either do not pertain to its core business operations or their exclusion may facilitate better comparability between periods and for peer comparison purposes. The tax-equivalent adjustment to net interest income and net interest margin recognizes the income tax savings when comparing taxable and tax-exempt assets. Interest income and yields on tax-exempt securities and loans are presented using the current federal income tax rate of 21%. Management believes that it is standard practice in the banking industry to present net interest income and net interest margin on a fully tax-equivalent basis and that it may enhance comparability for peer comparison purposes. In management's view, tangible common equity measures are capital adequacy metrics that may be meaningful to the Company, as well as analysts and investors, in assessing the Company's use of equity and in facilitating comparisons with peers. These non-GAAP measures are valuable indicators of a financial institution's capital strength since they eliminate intangible assets from stockholders' equity and retain the effect of accumulated other comprehensive loss in stockholders' equity. Although intended to enhance investors' understanding of the Company's business and performance, these non-GAAP financial measures should not be considered an alternative to GAAP. In addition, these non-GAAP financial measures may differ from those used by other financial institutions to assess their business and performance. See the following reconciliations in the "Non-GAAP Reconciliations" section for details on the calculation of these measures to the extent presented herein. 1 Includes expenses related to the tragic April 10 event at our downtown Louisville location
