Market operator ASX Ltd is set for more change at the top after chief financial officer Gillian Larkins said she would leave the company at the end of August, without specifying her next role.

The resignation is the latest in a string of executive changes at the company, including the departure of head of listings Max Cunningham in April. It follows an announcement made in early June that ASX’s head of markets, Helen Lofthouse, would succeed current chief executive Dominic Stevens.
