Activist investor Dan Plants of Voce Capital Management LLC on Monday issued a letter to the board of Air Methods Corp. taking issue with the company’s share price and suggesting that he is “prepared” to nominate dissident director candidates soon at the emergency medical air transportation company, in what is the activist’s latest escalation in a multi-year insurgency. Specifically, Plants argued in a letter to Air Methods board that the company continues to destroy stockholder value, is deeply undervalued, has an over-tenured board and has some “serious operational issues.”
