Michigan City-based Horizon Bancorp Inc. has completed its more than $135 million acquisition of Salin Bancshares Inc. in Indianapolis. As a result, all 20 Salin Bank and Trust Co. locations will be rebranded under the Horizon name. The acquisition was first announced in October. The closing of the deal brings the number of offices for Horizon to nearly 90 throughout Indiana and Michigan. Horizon says the acquisition enhances its core deposit base and expands its presence with new offices in Fort Wayne and Columbus and additional offices in Indianapolis and Lafayette.
