“Arverne Group, positioned in the fast-growing geothermal heat and lithium markets, has developed a unique strategy for harnessing subsurface natural resources, ensuring a sovereign and competitive energy transition. In 2024, we demonstrated the relevance of our model from the design of facilities for geothermal heat to the exploitation and completed the geothermal installation at Roissy Charles de Gaulle airport, thereby contributing to its decarbonisation. In 2025, the Group is anticipating significant milestones: the launch of the pre-industrial phase of our innovative project combining geothermal heat and lithium in Alsace and the signing of contracts confirming our first geothermal heat production in 2026. Since the transfer to the Euronext’s general sub-fund, we are particularly pleased to welcome new individual shareholders, alongside our long-standing shareholders. I would like to thank all of the Group’s teams for their commitment and their hard work for the benefit of the regions.” said Pierre Brossollet, founder and CEO of Arverne Group.
