About Arverne Group S.A.

ARVERNE GROUP S.A. (ISIN FR001400JWR8, ticker ARVEN) is a French industrial company focused on harnessing renewable underground resources, with a core strategy built around geothermal energy and, in the medium term, geothermal lithium. Founded in Pau in 2018 by Pierre Brossollet, the group was created with the ambition of turning the subsoil into a local, low-carbon and sovereign energy source serving territories, public authorities and industrial customers. Arverne is now positioned as France’s leading supplier of geothermal solutions and operates as an integrated player across the value chain, from exploration and drilling to production and commercialization. The group’s business model is built around three complementary activities. First, Arverne provides geothermal heating and cooling through its subsidiary 2gré, offering solutions for buildings, district heating networks, industrial sites, farms and local authorities. Second, through Lithium de France, it develops geothermal lithium extraction and sales, aiming to contribute to a sovereign European supply chain for electric mobility and energy storage. Third, Arverne Drilling Services carries out deep drilling and well construction, giving the company control over a critical technical capability that is essential in geothermal projects. From a historical perspective, Arverne has organized itself into specialized subsidiaries to accelerate industrial deployment. The company strengthened its market visibility by listing on Euronext Paris, where it is also associated with the Tech Leaders segment, while maintaining its identity as a mission-driven company. This reflects a clear strategic emphasis on the energy transition, short supply chains, energy independence and the decarbonization of thermal uses. In recent months, Arverne has reached several operational milestones, including the launch of geothermal drilling for Lithium de France in Alsace and continued progress on its lithium development roadmap. The group emphasizes its ability to serve both public and private clients, with solutions tailored to the decarbonization of heat demand and, over time, the supply of low-carbon lithium. Its geographic footprint remains primarily French, anchored in Pau and with major projects in Alsace, but its industrial ambition is clearly European in scope. A notable recent development is the publication in March 2026 of its “Dual Flow” roadmap for 2031-2033, confirming ambitions in heating/cooling and geothermal lithium production. Supported by financial and industrial partners, this strategy highlights Arverne’s growth profile: still in an industrialization phase, but exposed to structurally attractive markets tied to energy sovereignty, transition infrastructure and reindustrialization.
