OLD NATIONAL BANCORP IN

The Company’s accounting and reporting policies conform to 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 users of the financial information 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 following table.

The Company presents net income per common share and net income applicable to common shares, adjusted for certain notable items. These items include merger-related charges associated with completed and pending acquisitions, debt securities gains/losses, separation expense, CECL Day 1 non-PCD provision expense, distribution of excess pension assets expense, FDIC special assessment expense, gain on sale of Visa Class B restricted shares, expenses related to the tragic April 10, 2023 event at our downtown Louisville location (“Louisville expenses”), contract termination charge, and property optimization charges. Management believes excluding these items from net income per common share and net income applicable to common shares may be useful in assessing the Company's underlying operational performance since these items do not pertain to its core business operations and their exclusion may facilitate better comparability between periods. Management believes that excluding merger-related charges 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 taxable 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 users of the financial information, 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 shareholders’ equity and retain the effect of AOCI in shareholders’ equity.

Although intended to enhance 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 previously provided tables and the following reconciliations in the “Non-GAAP Reconciliations” section for details on the calculation of these measures to the extent presented herein.
