Arverne Group S.A. Announces the Start of Drilling of the First Geothermal Doublet At the Schwabwiller Site in Alsace Arverne Group S.A. announced the start of drilling of the first geothermal doublet at the Schwabwiller site in Alsace. In accordance with the established schedule, following site preparation work, Arverne's teams are beginning drilling operations. On the surface, the two wells will be spaced 10 meters apart and will gradually move further apart to reach a spacing of 1 kilometer at a depth of 2,400 meters. These initial drillings will confirm the flow rate, temperature, and lithium content of the geothermal fluid at this site. This phase will be crucial for collecting data that will help refine geological models and adapt technical protocols. The Lithium de France project will actively contribute to the energy transition by providing carbon-free geothermal heat to businesses, farms, and local communities in northern Alsace via a short supply chain. The geothermal brines, rich in critical metals, will also be used to produce low-carbon lithium to support electric mobility. Overall, this project will enhance the attractiveness of the region and generate nearly 200 direct jobs in the area. By exploiting geothermal heat, it will contribute to the decarbonization of the region and reduce CO2 emissions by up to 90% compared to natural gas heating3. The geothermal lithium produced will have a reduced environmental footprint, with approximately 70% less CO2 emissions compared to the lithium currently available on the market4. Drilling operations for the first doublet of the Lithium de France project will take place over a period of seven months and will contribute to gross business volume in 2025 and 2026. Arverne confirms and clarifies its 2025 forecasts, with gross activity volume expected to be between €25 million and €27 million, representing an increase of +45% to +55% compared to 2024.

New major risk - Revenue and earnings growth Revenue has declined by 5.8% over the past year. This is considered a major risk. Ultimately, shareholders want to see a good return on their investment and that generally comes from sharing in the company's profits. If revenues are declining, then it is difficult for the company to prevent its earnings from declining as well. A trend of falling revenue can be very difficult to turn around. If the company is well already established it may also be a sign the company has matured and is in decline. In addition, if the company pays dividends it will also likely need to reduce or cut them, striking a dual blow to total shareholder returns. This is currently the only risk that has been identified for the company. Reported Earnings • Mar 31
