Roundy's, a midwest supermarket chain with 158 stores in Wisconsin, Minnesota and Illinois, announced terms for its IPO on Thursday. The Milwaukee, WI-based company plans to raise $200 million by offering 18 million shares (38% insider) at a price range of $10.00 to $12.00. At the mid-point of the proposed range, Roundy's will command a market value of $456 million. Roundy's operates under the Pick 'n Save, Rainbow, Copps, Metro Market and Mariano's Fresh Market banners. Sales in the most recent quarter rose 4% to $977 million. CEO Robert Mariano and CFO Darren Karst held the same roles at Dominick's Finer Foods, which operated 116 grocery stores at the time of its acquisition by Safeway in 1998. Roundy's, which was founded in 1872, plans to list on the New York Stock Exchange under the symbol RNDY. Credit Suisse, J.P. Morgan, Jefferies, Baird and BMO Capital Markets are the lead underwriters on the deal.
