Among other risks, the ongoing COVID-19 pandemic may significantly affect the banking industry, the health and safety of the Company’s employees, and the Company’s business prospects. The ultimate impact of the COVID-19 pandemic on our business and financial results will depend on future developments, which are highly uncertain and cannot be predicted, including the scope and duration of the pandemic, the impact on the economy, our customers, our employees and our business partners, the safety, effectiveness, distribution and acceptance of vaccines developed to mitigate the pandemic, and actions taken by governmental authorities in response to the pandemic. The Company does not undertake, and specifically disclaims any obligation, to update any forward-looking statements to reflect occurrences or unanticipated events or circumstances after the date of such statements, except as required by law. Any statements about future operating results, such as those concerning accretion and dilution to the Company’s earnings or shareholders, are for illustrative purposes only, are not forecasts, and actual results may differ.
