39 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 supplements to GAAP, which is used to prepare the Company’s financial statements, and shou ld 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.

40 Reconciliation of Non - GAAP Disclosures 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. (1) Includes expenses related to PPP loan forgiveness and PPP round two loan set - up, expenses incurred related to the Company’s response to COVID - 19, gains on the sale of closed branches, costs related to the Company’s closure of branches, merger - related costs, rebranding expenses, severance expenses, and losses on debt extinguishment (2) Includes unrealized losses related to SBIC Investment due to COVID - 19, insurance proceeds, gains related to the sale of Shor e Premier, and gains related to the sale of the Company’s ownership interest in a payments - related company ADJUSTED OPERATING EARNINGS & FINANCIAL METRICS For the three months For the nine months ended ended For the years ended (Dollars in thousands, except per share amounts) September 30, 2021 September 30, 2021 2020 2019 2018 2017 2016 Net Income Net income (GAAP) 74,565$ 216,138$ 158,228$ 193,528$ 146,248$ 72,923$ 77,476$ Plus: Merger and rebranding-related costs net of tax - - - 27,395 32,065 4,405 - Plus: Nonrecurring tax expenses - - - - - 6,250 - Plus: Net loss related to balance sheet repositioning, net of tax - 11,609 25,979 12,953 - - - Less: Gain on sale of securities, net of tax 7 69 9,712 6,063 303 520 133 Adjusted operating earnings (non-GAAP) 74,558$ 227,678$ 174,495$ 227,813$ 178,010$ 83,058$ 77,343$ Less: Dividends on preferred stock 2,967 8,901 5,658 - - - - Adjusted operating earnings available to common shareholders (non-GAAP) 71,591$ 218,777$ 168,837$ 227,813$ 178,010$ 83,058$ 77,343$ Earnings per share (EPS) Weighted average common shares outstanding, diluted 76,322,736 78,007,543 78,875,668 80,263,557 65,908,573 43,779,744 43,890,271 EPS available to common shareholders, diluted (GAAP) 0.94$ 2.66$ 1.93$ 2.41$ 2.22$ 1.67$ 1.77$ Adjusted operating EPS available to common shareholders, diluted (non-GAAP) 0.94$ 2.80$ 2.14$ 2.84$ 2.70$ 1.90$ 1.76$ Return on assets (ROA) Average Assets 20,056,570$ 19,890,155$ 19,083,853$ 16,840,310$ 13,181,609$ 8,820,142$ 8,046,305$ ROA (GAAP) 1.47% 1.45% 0.83% 1.15% 1.11% 0.83% 0.96% Adjusted operating ROA (non-GAAP) 1.47% 1.53% 0.91% 1.35% 1.35% 0.94% 0.96% Return on equity (ROE) Adjusted operating earnings available to common shareholders (non-GAAP) 71,591$ 218,777$ 168,837$ 227,813$ 178,010$ 83,058$ 77,343$ Plus: Amortization of intangibles, tax effected 2,671 8,436 13,093 14,632 10,143 3,957 4,687 Adjusted operating earnings available to common shareholders before amortization of intangibles (non-GAAP) 74,262$ 227,213$ 181,930$ 242,445$ 188,153$ 87,015$ 82,030$ Average equity (GAAP) 2,718,032$ 2,728,605$ 2,576,372$ 2,451,435$ 1,863,216$ 1,030,847$ 994,785$ Less: Average intangible assets 983,739 987,288 1,000,654 991,926 776,944 315,722 318,131 Less: Average perpetual preferred stock 166,356 166,356 93,658 - - - - Average tangible common equity (non-GAAP) 1,567,937$ 1,574,961$ 1,482,060$ 1,459,509$ 1,086,272$ 715,125$ 676,654$ ROE (GAAP) 10.88% 10.59% 6.14% 7.89% 7.85% 7.07% 7.79% Return on tangible common equity (ROTCE) Net income available to common shareholders (GAAP) 71,598$ 207,237$ 152,570$ 193,528$ 146,248$ 72,923$ 77,476$ Plus: Amortization of intangibles, tax effected 2,671 8,436 13,093 14,632 10,143 3,957 4,687 Net income available to common shareholders before amortization of intangibles (non- GAAP) 74,269$ 215,673$ 165,663$ 208,160$ 156,391$ 76,880$ 82,163$ ROTCE 18.79% 18.31% 11.18% 14.26% 14.40% 10.75% 12.14% Adjusted operating ROTCE (non-GAAP) 18.79% 19.29% 12.28% 16.61% 17.32% 12.17% 12.12%

41 Reconciliation of Non - GAAP Disclosures PPP adjustment impact excludes the SBA guaranteed loans funded during 2020 and 2021. 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 SBA guarantee.
