A Health Management Associates shareholder is looking to stop the sale of the Naples-based company to a Tennessee company with a class-action lawsuit. "The proposed acquisition does not adequately reflect the company's value and will unfairly divest Health Management's public shareholders of their interests in the company," wrote Justtini Aliaga in a lawsuit filed Thursday in Collier Circuit Court [FL]. Aliaga claims the undervalued sale is an easy way for HMA to avoid many of its legal and regulatory problems.
