In addition, the following risks related to the transaction in particular could cause actual results to differ materially from these forward-looking statements: ability to obtain regulatory approvals and meet other closing conditions to the merger, including approval by First American shareholders, on the expected terms and schedule; delay in closing the merger; difficulties and delays in integrating the RBB and First American businesses or fully realizing cost savings and other benefits; business disruption following the proposed transaction Any statements about future operating results, such as those concerning accretion and dilution to RBB’s earnings or shareholders, are for illustrative purposes only, are not forecasts, and actual results may differ.
