Sale of Héli-Union to Sabena Technics

Paris (France), 6th October 2022,

Financière de Courcelles advised Compagnie Nationale de Navigation (CNN) on the sale of Héli-Union to Sabena Technics.

With 350 employees, Héli-Union is a European leader in the support and maintenance of helicopter fleets, serving governments and private clients worldwide. Currently active in six countries, Héli-Union is also a specialised air operator with its own fleet of helicopters.

The acquisition of Heli-Union is in line with Sabena’s strategy – supported by Sagard, Towerbrook and BPI – to strengthen its position as a key player in the military helicopter maintenance sector. Héli-Union will represent approximately a third of Sabena’s consolidated turnover.

The Financière de Courcelles team is delighted to have supported CNN in this sale, thus confirming its strong momentum in the defence sector.
