In a statement, ASIC said Queensland man Gregory Campbell had appeared in the County Court of Victoria and pleaded guilty to one count of insider trading.
Mr Campbell had been a member of the executive team of private hospital operator Healthe Care in 2016, and purchased almost 400,000 shares in listed rival Pulse Health, worth approximately $127,000, with possession of inside information relating to Pulse.
The company received a takeover offer in late October 2016, after which Mr Campbell had sold the shares for a profit of more than $30,000, according to ASIC's case.
Mr Campbell is due to be sentenced on 12 October 2021.
He was charged in 2018 following an ASIC investigation.
