Ports and power magnate reorganized his $10 billion (revenues) empire by spinning off the ports, power and transmission units from flagship Adani Enterprises, causing the latter's shares to plunge 80% on a single day in June. Despite support from former Australian prime minister Tony Abbott, Adani's controversial coal-mining project in Australia suffered a setback when a federal court revoked environmental approval and some banks backed out in August. While the group denied rumors that it had ended its $4 billion joint venture with Sun Edison to make low-cost solar panels, Adani has reportedly started discussions with Foxconn and Japan's SoftBank for the solar venture.
