About Pierre Brossollet

Pierre Brossollet is the founder, Chief Executive Officer, and Chairman of the Board of Arverne Group, a French listed company on Euronext Paris focused on geothermal energy and subsurface solutions for the energy transition. He also chairs the board committee dedicated to strategy, risks and CSR, which places him at the center of both governance and long-term industrial direction. His role combines entrepreneurial leadership, corporate oversight, and execution of the group’s growth strategy. An energy-sector entrepreneur, Pierre Brossollet has more than 20 years of experience in the industry. Arverne’s reference documents describe him as having built his career around subsurface resources and energy infrastructure before founding Arverne in 2018 in Pau, at the Hélioparc technology park. This background suggests a deep operational understanding of technically demanding, capital-intensive energy projects, as well as the ability to translate industrial expertise into a scalable business platform. Under his leadership, Arverne has been positioned as an industrial platform dedicated to geothermal energy, geothermal lithium, and related subsurface applications, with the stated goal of accelerating industrial decarbonization. A major milestone came in 2023, when Arverne became publicly listed on Euronext Paris following its business combination with Transition. That transaction improved the group’s access to capital and strengthened its profile as an emerging specialist in the energy transition. Brossollet has emphasized the company’s ability to leverage unique know-how across the full subsurface value chain. At Arverne, he is driving a strategy of industrial scale-up through organic development, partnerships, and operational ramp-up. His public statements consistently point to a long-term ambition: to build a leading French player in subsurface resources capable of investing at scale in a market that is still structurally underdeveloped. In 2024 and 2025, he remained the face of the group in annual general meetings and strategic announcements, confirming his central role in both stakeholder relations and the execution of Arverne’s industrial roadmap.
