HealthSpring, one of the largest managed care organizations in the U.S. whose primary focus is the Medicare Advantage market, announced Thursday morning that it will offer 17.0 million shares at a range of $16 to $18. Insiders plan to sell 5.0 million of the shares. Assuming the stock prices at the midpoint, the TN based company will have an initial market capitalization of $1.0 billion. Goldman Sachs, Citigroup and UBS Investment Bank will be the joint book runners on the deal. Timing has yet to be released.
