Shares of Mednax are moving higher after Paul Singer’s Elliott Associates this morning disclosed an activist stake in the provider of physician services. Elliott has a combined economic exposure in the company of approximately 7.0%. The activist believes the shares are “undervalued” and seeks to engage in a “constructive dialogue” with management and the board “regarding strategic options and operational opportunities to maximize shareholder value.” Elliott believes that there is “substantial upside” from Mednax’s unaffected share price level of $43.37 per share, the closing price on November 3, the last trading day prior to the fund’s increased share accumulation and prior to news reports of private equity interest in the space. Elliott added that its talks could pertain to a sale of the company or certain of its businesses or assets. Mednax is up 10%, or $4.35, to $50.01 in late morning trading.
