PRESS RELEASE


Arverne Group contributes to the energy transition of E.Leclerc
supermarkets through geothermal energy


Pau, June 5, 2025 – Arverne Group (ISIN code : FR001400JWR8, mnemonic code ARVEN), a
French industrial company specialized in the production of renewable underground resources,
welcomed Michel-Édouard Leclerc, Chairman of the E.Leclerc Group, to the geothermal drilling site
of the Frouard supermarket (Grand Est region) on June 4, 2025.

This 22,000 m² commercial site will be the first in France to integrate geothermal energy to cover part
of its energy needs. By harnessing the constant temperature of the ground, the system will provide
heating. As part of this project, Arverne Group is carrying out 53 shallow geothermal drillings, each
150 meters deep, beneath the existing parking lot. The three-month-long work involves a team of
nine people dedicated to drilling, while another team will handle the connection.

The installation of this geothermal solution is fully in line with E.Leclerc Group’s environmental
strategy, which also includes the deployment of LED lighting, the installation of photovoltaic panels,
and the addition of charging stations in its parking lots.

Pierre Brossollet, Founder and CEO of Arverne Group : “We are proud to support the E.Leclerc group
by bringing our expertise to this first geothermal energy project. We thank them for their trust and hope
that this collaboration marks the beginning of a lasting momentum around a renewable, discreet,
decarbonized, and sovereign energy source, perfectly aligned with the environmental and energy
challenges facing the large-scale retail sector.”
