The Sundance Energy Australia Ltd (ASX: SEA) share price has crashed 27% lower to 19 cents after the energy producer announced its decision to re-domicile from Australia to the United States via a proposed scheme of arrangement. The scheme remains subject to shareholder, judicial and regulatory approvals, but if approved, the company will transfer its primary listing to Nasdaq and cease to trade on the ASX. The board has unanimously recommended the scheme.
