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 tables of this release.

The Company presents EPS, the efficiency ratio, return on average common equity, and return on average tangible common equity, all adjusted for certain notable items. These items include the CECL Day 1 non-PCD provision expense, merger related charges associated with completed acquisitions, ONB Way charges, and net securities gains. 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 loans excluding PPP loans, as well as deposits, both on a historical combined basis and excluding acquisition accounting adjustments. Management believes that comparisons of balance sheet balances to legacy periods are not meaningful due to the merger with First Midwest. Additionally, management believes that excluding acquisition accounting adjustments may be useful to the Company, as well as analysts and investors, since these adjustments can vary significantly based on the size, type, and structure of each acquisition.

Income tax expense, provision for credit losses, and the certain notable items listed above are excluded from the calculation of pre-provision net revenues, adjusted due to the fluctuation in income before income tax and the level of provision for credit losses required. Management believes pre-provision net revenues, adjusted may be useful in assessing the Company's underlying operational performance and their exclusion may facilitate better comparability between periods and for peer comparison purposes.

The Company presents adjusted noninterest expense, which excludes merger related charges, ONB Way charges and amortization of tax credit investments. Management believes that excluding these items from noninterest expense 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 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.
