The results represent an increase of more than €7 million in revenue compared to 2015, mostly because of a growth in assets across the group.
The firm said its 2016 growth showed stable development in two leading product areas, namely Professional Congress Organisation (PCO) and meetings.
AIM Group International president Gianluca Buongiorno said: "All key indicators are positive and we continue to see improvements across the board. We will continue to leverage this growth into smart investments, acquisition and growth."
The company reported "strong advancement" in the healthcare sector and a client portfolio made up of association and corporate clients.
Managing director Gianluca Scavo said: "We are very satisfied with the 2016 results and are exploring new opportunities to expand our portfolio and services to develop strong partnerships with our clients."
The group said it has managed more than 2.000 projects and more than 20 as Core PCO, alongside a stable increase in global accounts.
