2 2 Special Note Concerning Forward - Looking Statements Statements made in this document, other than those concerning historical financial information, may be considered forward - looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations, plans, objectives, future performance and business of the Company. Forward - looking statements, which may be based upon beliefs, expectations and assumptions of the Company’s management and on information currently available to management, are generally identifiable by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,” “may,” “will,” “would,” “could,” “should” or other similar expressions. Additionally, all statements in this document, including forward - looking statements, speak only as of the date they are made, and the Company undertakes no obligation to update any statement in light of new information or future events. A number of factors, many of which are beyond the Company’s ability to control or predict, could cause actual results to differ materially from those in the Company’s forward - looking statements. These factors include, among others, the following: ( i ) the strength of the local, state, national and international economy (including the impact of the 2020 presidential election and the impact of tariffs, a U.S. withdrawal from or significant negotiation of trade agreements, trade wars and other changes in trade regulations); (ii) the economic impact of any future terrorist threats or attacks, widespread disease or pandemics (including the COVID - 19 pandemic in the United States), or other adverse external events that could cause economic deterioration or instability in credit markets; (iii) changes in state and federal laws, regulations and governmental policies concerning the Company’s general business; (iv) changes in accounting policies and practices, including CECL, that changed how the Company estimates credit losses; (v) changes in interest rates and prepayment rates of the Company’s assets (including the impact of The London Inter - bank Offered Rate phase - out); (vi) increased competition in the financial services sector and the inability to attract new customers; (vii) changes in technology and the ability to develop and maintain secure and reliable electronic systems; (viii) the loss of key executives or associates; (ix) changes in consumer spending; (x) unexpected results of current and/or future acquisitions, which may include failure to realize the anticipated benefits of the acquisition and the possibility that the transaction costs may be greater than anticipated; (xi) unexpected outcomes of existing or new litigation involving the Company; and (xii) the economic impact of exceptional weather occurrences such as tornadoes, hurricanes, floods, and blizzards. These risks and uncertainties should be considered in evaluating forward - looking statements and undue reliance should not be placed on such statements. Additional information concerning the Company and its business, including additional factors that could materially affect its financial results, is included in the Company’s filings with the Securities and Exchange Commission.

3 3 Non - GAAP Financial Measures This document contains financial information determined other than in accordance with accounting principles generally accepted in the United States of America (“GAAP”). Management uses these “non - GAAP” measures in its analysis of the Company’s performance. Management also believes that these non - GAAP financial measures allow for better comparability of period to period operating performance. Additionally, the Company believes this information is utilized by regulators and market analysts to evaluate a company’s financial condition, and therefore, such information is useful to investors. These disclosures should not be viewed as a substitute for operating results determined in accordance with GAAP, nor are they necessarily comparable to non - GAAP performance measures that may be presented by other companies. A reconciliation of the non - GAAP measures used in this document to the most directly comparable GAAP measures is provided beginning on page 32 of this document. For more details on the Company’s non - GAAP measures, refer to the Company’s Annual Report on Form 10 - K for the year ended December 31, 2019 and the Company’s Quarterly Report on Form 10 - Q for the quarter ended June 30, 2020.

22 22 Current Expected Credit Loss (CECL) Model ▪ On January 1, 2020, the Company adopted ASU 2016 - 13 (Topic 326), “Measurement of Credit Losses on Financial Instruments,” commonly referenced as the CECL model. Upon adoption of CECL, we recognized: - $16.8 million increase in our allowance for credit losses, substantially attributable to the remaining loan fair value marks on prior acquisitions - $5.5 million increase in our reserve for unfunded commitments (carried in other liabilities) - Total Day 1 increase of 41.54% over 12/31/19 reserve balance - These one - time increases, net of tax, were $15.9 million and recorded as an adjustment to beginning retained earnings ▪ During the first quarter of 2020, the Company recorded provision for credit losses of $17.2 million and provision for unfunded commitments of $1.0 million primarily as a result of economic factors around COVID - 19 ▪ During the second quarter of 2020, the Company recorded provision for credit losses of $12.9 million and provision for unfunded commitments of $0.6 million - While our portfolio has not yet demonstrated material indications of weakness, provisioning under CECL reflects deteriorating economic conditions and expectations for credit stress to emerge in future periods - June 30, 2020 increase of 91.86% over 12/31/19 reserve balance and 13.45% over Q1 2020 - Ongoing impacts of the CECL methodology will be dependent upon changes in economic conditions and forecasts, originated and acquired loan portfolio composition, credit performance trends, portfolio duration, and other factors ▪ Increase in allowance for credit losses moves allowance for credit losses as a percentage of portfolio loans to 1.48% at June 30, 2020 (excludes PPP loans) and allowance for credit losses as a percentage of non - performing loans to 378.43%
