CoBiz Financial, the Denver-based financial services holding company, is to acquire Wagner Investment Management, an SEC-registered investment advisor with approximately $900 million in assets under management. Wagner, which provides investment services for high-net-worth individuals and families, foundations and non-profit organisations, will continue to operate under its current name and management team. The deal, for an undisclosed sum, is expected to close by the end of 2007. CoBiz operates Colorado Business Bank and Arizona Business Bank, full-service commercial banks that offer services to a targeted customer base of professionals and small to mid-sized businesses. It said Wagner would supplement the investment services currently offered by Alexander Capital Management Group and CoBiz Trust, which provides trust administration and estate settlement services.
