26 Reconciliation of Non - GAAP Disclosures The Company has provided supplemental performance measures on a tax - equivalent, tangible, operating, adjusted, or pre - tax pre - pr ovision basis. These non - GAAP financial measures are a supplement to GAAP, which is used to prepare the Company’s financial statements, and sho uld not be considered in isolation or as a substitute for comparable measures calculated in accordance with GAAP. In addition, the Compa ny’ s non - GAAP financial measures may not be comparable to non - GAAP financial measures of other companies. The Company uses the non - GAAP financ ial measures discussed herein in its analysis of the Company’s performance. The Company’s management believes that these non - GAAP fi nancial measures provide additional understanding of ongoing operations, enhance comparability of results of operations with prior pe rio ds and show the effects of significant gains and charges in the periods presented without the impact of items or events that may obscure tren ds in the Company’s underlying performance.

27 Reconciliation of Non - GAAP Disclosures Adjusted operating measures exclude merger and rebranding - related costs, nonrecurring tax expenses, the gains or losses related to balance sheet repositioning (principally composed of gains and losses on debt extinguishment), gains or losses on sale of securities , gains on the sale of Visa, Inc. Class B common stock, gain on the sale DHFB, as well as branch closing and facility consolidation costs (principally composed of real estate, leases and other assets write downs, as well as severance associated with branch closing and corporate expense reduction initiatives). The Company believes these non - GAAP adjusted measures provide investors with important information about the continuing economic results of the organization’s operations. Non - GAAP adjusted measures for prior periods reflect adjustments for previously announced branch closing and corporate expense reduction initiatives. Tangible assets and tangible common equity are used in the calculation of certain profitability, capital, and per share ratios. The Company believes tangible assets, tangible common equity and the related ratios are meaningful measures of capital adequacy because they provide a meaningful base for period - to - period and company - to - company comparisons, which the Company believes will assist investors in assessing the capital of the Company and its ability to absorb potential losses. 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.

28 Reconciliation of Non - GAAP Disclosures PPP adjustment impact excludes the unforgiven portion of PPP loans. The Company believes loans held for investment (net of deferred fees and costs), excluding PPP is useful to investors as it provides more clarity on the Company’s organic growth. The Company believes that the ALLL as a percentage of loans held for investment (net of deferred fees and costs), excluding PPP, is useful to investors because of the size of the Company’s PPP originations and the impact of the embedded credit enhancement provided by the Small Business Administration guarantee.
