Mirova, a french investment management firm, agreed to acquire an 80% stake in Altiservice, the private ski operator, from Engie, which offers a full range of electricity, gas and associated energy and environment services throughout the world. Financial terms were not disclosed. Altiservice, which manages the first and third ski resorts of the French Pyrenees, Saint-Lary and Font Romeu-Pyrénées 2000, has changed its shareholder by public service delegation majority. With the support of its new shareholder, Altiservice plans to invest in snow cannons, track works and even ski lifts at Font Romeu-Pyrénées 2000 and Saint-Lary. "Engie wanted to refocus on renewable energies and we looked for a new partner to invest in the resorts," Yves Rougier, CEO of Altiservice.
