Nabiax is a Spanish colocation and data center operator, formed in 2019 when investment firm Asterion Industrial Partners acquired eleven former Telefónica data centers. As of 2024-2025 the company’s active physical portfolio is concentrated in Spain, with three campus locations — two in the Madrid region (Alcalá de Henares and Julián Camarillo) and one in the Barcelona area (Terrassa) — after it divested its eleven Latin American facilities to Actis in 2023 to refocus on the European market. Nabiax describes itself as Spain’s leading colocation company and a key hyperscaler platform by market share and installed capacity, with an installed IT power of roughly 35 MW as of late 2024 and stated expansion plans that could scale the portfolio to over 100 MW. In November 2024, Asterion agreed to sell Nabiax to a fund managed by Aermont Capital, a Keppel-linked European real estate investment group, with the transaction including the buyout of Telefónica’s remaining 20% equity stake in the company.
