Altarea announces major progress in data centers
at Choose France Summit
Press Release

Paris, November 17, 2025 – Altarea takes part today in the first edition of the Choose France
Summit – France Edition, which brings together French companies that have chosen to
invest in the national territory and actively contribute to economic dynamism and industrial
sovereignty. This event is an opportunity for the Group to reaffirm its ambition in the data
center sector in France.

Altarea has been active in the data center market for several years and has built a dedicated team
covering all data center formats. Today, the Group’s first projects are materializing in two main
segments:

• Colocation data centers, primarily for corporate clients: Following the commissioning
of its first project in Noyal-sur-Vilaine (3 MW IT), Altarea has obtained a building permit for
a second data center of 7 MW IT in Vélizy (Yvelines). In this segment, the Group is
developing a pipeline of sovereign data centers, particularly in the Île-de-France region,
representing a potential of more than 100 MW IT in the long term.

• Hyperscale data centers, primarily for AI: Altarea is working on the redevelopment of
several controlled land plots, including two for which grid connection authorizations (PTF)
have been obtained, securing an electrical capacity of 520 MW. For these two projects,
advanced discussions are underway with administrative and political authorities, as well as
financial and commercial partners.

These projects could represent several billion euros of investments to be committed over the
coming years. In line with its strategy, Altarea will implement these projects once fully secured and
within the framework of financial and commercial partnerships.

Alain Taravella, Chairman and Founder of Altarea: “Altarea’s mission has always been to meet
the essential needs of the French people. Today, digital transformation is a top priority, essential
to our country’s competitiveness. Our understanding of territorial challenges, our ability to manage
complexity and mobilize capital, enable us to develop a comprehensive range of data centers that
set the standard for environmental performance.”

Roland Lescure, Minister of Economy, Finance and Industrial, Energy and Digital
Sovereignty in France: “To support the rise of digital technology in our country, we need national
operators investing in dedicated infrastructures adapted to territorial needs. I would like to
congratulate Altarea for its investments in data centers and its contribution to the development of
France’s digital infrastructure."
Anne Le Hénanff, Minister Delegate for Artificial Intelligence and Digital Affairs:
“Digital sovereignty is the guiding principle of my action, and I therefore congratulate Altarea for
this announcement, which contributes to it and demonstrates that we have all the assets to make
France a major AI power. Data centers are the backbone of digital transformation. The AI Action
Summit in Paris last February placed the development of data centers across the country at the
heart of our strategy. Today, as we host the first France Edition of Choose France in Paris, these
data center projects led by Altarea are a concrete realization of this strategy.”
