The European Investment Bank has agreed a €375 million loan with Cellnex to support 5G mobile infrastructure roll-out in Spain, France, Italy and Portugal. Cellnex is expected to use the financing to mobilise €770 million in total investment.
Why it matters
The project relies on an open-access model in which multiple mobile operators share the same sites rather than building separate masts. This is the third joint financing operation between the EIB and Cellnex for European mobile telecoms infrastructure.
The €375 million loan is set against a projected €770 million total investment across four countries. The project combines new mobile towers, urban sites, distributed antenna systems and upgrades enabling multi-operator site sharing, though the stub does not give capacity or performance specifications.
The players
European Investment Bank
The European Investment Bank is the European Union's public bank that finances infrastructure and innovation projects across member states.
Cellnex
Cellnex is a Barcelona-based company that owns and operates telecommunications towers and wireless infrastructure across Europe.
The details
The financing supports new mobile towers and urban sites, along with upgrades that let more than one mobile network operator use the same site. The project also includes investment to modernise Spain's digital terrestrial television network. About half of the new masts are expected to be installed in cohesion regions.

The Tech Race
This is the third joint operation between the European Investment Bank and Cellnex to finance mobile telecoms infrastructure in Europe. It extends a pattern of public-bank co-financing for shared 5G site networks across the continent.
Shared sites built under this model could mean more mobile coverage and capacity in towns and cities across Spain, France, Italy and Portugal as operators use the same infrastructure. The stub does not say when the new sites will go live or how these changes will affect pricing for subscribers.
The takeaway
Shared 5G sites reduce the need for each operator to build separate masts, which can speed coverage and lower duplication. Public financing from the EIB is helping make that model work at European scale.
