Siobhan Lennon, the chief executive of Post Publications - which publishes The Sunday Business Post - has said she is stepping down from her position.
Ms Lennon has been CEO since 2016.
In a statement, she said her decision to leave the business was simply a matter of timing.
"I am proud to leave the business in a strong position, having overseen the transition of ownership, its return to profitability and our recent victory in a landmark court case," Ms Lennon said.
"I have been involved in developing a new strategy for the business and believe the company is well set for the next stage of its development," she added.
Enda O'Coineen, of Kilcullen Kapital, bought Post Publications in 2018.
"The owners plan to invest in the business based on its new strategy and I feel that this is the right time for me to hand over the reins," Ms Lennon said.
Ms Lennon said she will stay in her position until a new CEO is found to help manage the transition process.
Enda O'Coineen paid tribute to Ms Lennon, saying that she oversaw the company's return to profitability last year.
"She was instrumental in the successful sale of the business in 2018 and she played a key role working with us to bed down that acquisition over the last number of months," he added.
