Bernard Reilly, chief executive of Australian Retirement Trust, is to depart the fund in February 2024.
Reilly was appointed to lead ART in March 2021 and the fund was formed in February 2022 from the merger of QSuper and Sunsuper.
He was previously chief executive at Sunsuper from 2019.
In a statement, the fund's chair Andrew Fraser said: "Bern will leave an incredible legacy, having played an integral role in delivering Australia’s largest superannuation merger to create Australian Retirement Trust back in February 2022.
“Bern has expertly guided Australian Retirement Trust to deliver merger benefits to our more than 2.3 million members and grow funds under administration to more than $260b. But I think the thing Bern should be proudest of, and a true testament to his leadership capabilities, is the culture he has helped grow across our organisation.”
ART has appointed Egon Zehnder to commence a global executive search for a new CEO.
The super fund has welcomed two experienced leaders to the fold.
Insignia Financial has announced the appointment of an ex-ASIC commissioner to the board of its superannuation arm, before she takes over as chair in November.
The fund has announced an internal appointment to succeed Tim Barber, who is set to take up a new role at Marsh McLennan.
The $85 billion fund is reinforcing its commitment to simplicity with a refreshed visual brand identity.
