Forward-looking statements are statements that include projections, predictions, expectations, or beliefs about future events or results that are not statements of historical fact. Such forward-looking statements are based on various assumptions as of the time they are made, and are inherently subject to known and unknown risks, uncertainties, and other factors, some of which cannot be predicted or quantified, that may cause actual results, performance, or achievements to be materially different from those expressed or implied by such forward-looking statements.

2021 Operating Environment – Managing through the Pandemic 21 Soundness Profitability Growth During challenging times, it is important to remember our governing philosophy –“Soundness, Profitability, & Growth – in that order of priority”  This core philosophy is serving us well as we manage the Company through the current coronavirus pandemic crisis. We continue to effectively manage through the pandemic with an intense focus on:  Taking care of our Teammates and clients – they will remember how we treated them during this period.  Mitigating credit risk – batten down the hatches and protect the Bank by working with our business and consumer clients to assist them through these tough times.  Aligning the expense base to the lower for longer interest rate environment – ensure sustained top tier financial performance on the other side.

Reconciliation of Non-GAAP Disclosures 27 Operating Earnings Per Share The Company has provided supplemental performance measures on a tax-equivalent, tangible, operating, adjusted, or pre-tax pre-provision basis. These non-GAAP financial measures are supplements to GAAP, which is used to prepare the Company’s financial statements, and should not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, the Company’s non-GAAP financial measures may not be comparable to non-GAAP financial measures of other companies. The Company uses the non-GAAP financial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non-GAAP financial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure trends in the Company’s underlying performance.

Reconciliation of Non-GAAP Disclosures 28 Operating Earnings Per Share Adjusted operating measures exclude the after-tax effect of merger and rebranding-related costs unrelated to the Company’s normal operations. In addition, adjusted operating measures exclude the gains or losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment) and gains or losses on sale of securities. The Company believes these non-GAAP adjusted measures provide investors with important information about the combined economic results of the organization’s operations Additionally, the Company believes that return on tangible common equity (ROTCE) is a meaningful supplement to GAAP financial measures and useful to investors because it measures the performance of a business consistently across time without regard to whether components of the business were acquired or developed internally.
