Astrup Fearnley chief executive Even Matre Ellingsen is leaving the company after less than three years in the role.
He will be replaced by John Olav Harr, who is currently group chief operating officer.
Ellingsen took over the helm at the company, which is the parent of Norwegian shipbroker Fearnleys, from Jon-Aksel Torgersen at the end of 2018. Torgersen had been in charge of Astrup Fearnley for 26 years.
The departing CEO said he has some ideas of possible future jobs and that it is likely that they will be found outside Norway.
"I simply wanted to try something else," he said when asked what is driving him to leave.
Before becoming group chief executive, Ellingsen had been CEO at investment banking division Fearnley Securities for seven years. He also has worked at rival Pareto.
According to the annual report for 2020, 59-year-old Ellingsen had a salary of NOK 13.3m ($1.5m) last year.
Harr will now have the title of managing director of Astrup Fearnley Holding.
There have been other changes at the top of Fearnleys.
Former John Fredriksen lieutenant Marius Hermansen joined last month to take charge of the investment banking and broking business at the company. The move marks a return for the executive, who previously spent 10 years with Fearnleys.
Since the arrival of Hermansen, Ellingsen has focused on overseeing the group's real estate portfolio.
Astrup Fearnleys is owned by a non-profit foundation.
