Radiant Systems, the Atlanta-based POS specialist, has raised about $56.4 million in a public offering of 3.5 million of its shares and another 1,193,848 shares from selling shareholders. The offering price was $17 per share, with the underwriters exercising the full over allotment of 2,062 shares from the company and 702,105 shares from stockholders. The offering was priced about the time I was working on list week's issue which reported the projected range.
