CoastalSouth Bancshares, a bank holding company, completed the acquisition of Cornerstone Bancshares, a provider of banking services. Financial terms were not disclosed. "This acquisition will significantly enhance our presence in metro Atlanta, one of our primary growth markets. Financially, this is a very compelling transaction for both sets of shareholders. Steven Deaton and the team he has put together at Cornerstone have done a very good job of addressing legacy credit issues and, through the use of a contingent consideration mechanism in the merger agreement, we believe we have addressed the remaining credit issues in a conservative manner," Steve Stone, CoastalSouth President and CEO.
