the transaction, (6) the risks associated with achieving hiring plans, (7) the ability by each of Synovus and Pinnacle to obtain required governmental approvals of the proposed transaction on the timeline expected, or at all, and the risk that
such approvals may result in the imposition of conditions that could adversely affect the combined company after the closing of the proposed transaction or adversely affect the expected benefits of the proposed transaction, (8) reputational
risk and the reaction of each company’s customers, suppliers, employees or other business partners to the proposed transaction, (9) the failure of the closing conditions in the merger agreement to be satisfied, or any unexpected delay in
closing the proposed transaction or the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement, (10) the dilution caused by the issuance of shares of the combined company’s common
stock in the transaction, (11) the possibility that the proposed transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events, (12) risks related to management and oversight of the
expanded business and operations of the combined company following the closing of the proposed transaction, (13) the possibility the combined company is subject to additional regulatory requirements as a result of the proposed transaction or
expansion of the combined company’s business operations following the proposed transaction, (14) the outcome of any legal or regulatory proceedings or governmental inquiries or investigations that may be currently pending or later instituted
against Synovus, Pinnacle or the combined company and (15) general competitive, economic, political and market conditions and other factors that may affect future results of Synovus and Pinnacle including changes in asset quality and credit
risk; the inability to sustain revenue and earnings growth; changes in interest rates and capital markets; inflation; customer borrowing, repayment, investment and deposit practices; the impact, extent and timing of technological changes; and
