Shannon Group's chief executive Neil Pakey is to leave the company at the conclusion of his three-year contract next year.
Mr Pakey is due to leave in June and Shannon Group said it will now embark on the task of appointing his successor.
The Shannon Group is made up of four businesses which focus on delivering economic benefits for the west of Ireland and the wider national economy.
The companies are Shannon Commercial Properties, Shannon Airport, Shannon Heritage and Shannon IASC.
Shannon Group chairman Rose Hynes said that Mr Pakey came on board as CEO at an exciting time for Shannon as it embarked on life as an independent entity.
"During his tenure many milestones have been achieved. From an airport perspective we have returned Shannon to growth following five years of successive decline and by the end of 2015 passenger numbers will be up by 22% from where we started out," she said.
She also said that the transition of Shannon Commercial Properties - the property portfolio of the former Shannon Development - and the establishment of the International Aviation Services Centre at Shannon as a new business unit plus the formal establishment of the Group itself last year were also achieved.
"This has given the group a solid platform to achieve growth across all areas of the business with increased turnover, reduced costs and improved profits achieved since Neil took on this role," Ms Hynes said.
Mr Pakey said that he was looking forward to a new challenge having completed the agreed three-year term as CEO at Shannon Group.
