Under the terms of the merger agreement, AMRB shareholders will receive a fixed exchange ratio of 0.575 shares of Bancorp's common stock for each share of AMRB's common stock outstanding upon consummation of the Merger. AMRB had total assets of $916.1 million, total deposits of $788.6 million, and total loans of $475.4 million as of March 31, 2021. These amounts are subject to fair value adjustments upon the close of the Merger.
