Fortescue Metals has lost its chief financial officer, Christine Morris, just two months after she was appointed to the key position at the clean energy and iron ore group chaired by billionaire Andrew Forrest.

The exit was announced on Thursday evening barely three days after Fortescue’s chief executive, Fiona Hick, parted ways with the company after just six months in the job. In comments on Wednesday, Dr Forrest said Ms Hick did not agree with the company’s agenda, specifically to achieve zero emissions in its mining operations and its big bets on green hydrogen.
