Over the past years, Eurofiber Netz GmbH has significantly advanced the rollout of a high-performance fiber-to-the-home network in Berlin, establishing a strong regional presence with more than 150,000 homes passed. Following this successful build-out phase, the company is now entering a new stage of development, in which commercial utilization, marketing, and further economic development of the existing infrastructure will take center stage.

Against this backdrop, MIH Group has been identified as a strategic investor to support and further develop Eurofiber Netz GmbH in this next phase. MIH brings extensive experience in the development, operation, and expansion of fiber infrastructure and sees the acquisition as a logical extension of its strategic direction.

“We are proud of the progress made by the Eurofiber Netz team in building a high-performance fiber-to-the-home network in Berlin,” said Eurofiber Chief Operating Officer Eric Kuisch. “After five years of successful rollout of the network, the company is ready for its next phase of development under new ownership. This step supports Eurofiber’s strategy to focus on its core B2B digital infrastructure business across Europe, including in Germany. I would like to thank the Eurofiber Netz team and our Berlin partners for laying a strong foundation for the city’s digitization, and MIH for the constructive discussions regarding the company’s next chapter.”

For MIH Group, the acquisition represents an important milestone in building an integrated infrastructure approach that combines construction, operation, and increasingly, the commercialization of high-performance fiber networks. Eurofiber Netz GmbH is an excellent addition to MIH’s existing portfolio and opens up additional growth opportunities in one of Germany’s most important urban telecommunications markets.

Together with the Eurofiber Netz GmbH team, MIH aims to further develop the existing infrastructure under the new name mih Net Berlin GmbH, intensify the commercialization of the network, and lay the foundation for sustainable growth in Berlin.

“We are very pleased to support Eurofiber Netz GmbH as it opens a new growth chapter,” said Hajriz Brčvak, Founder and CEO of MIH Group. “The company is a perfect complement to our portfolio and a clear reflection of our expanded strategy to combine the construction and operation of fiber networks with the active commercialization of high-performance network infrastructure. We thank Eurofiber for the trust placed in us and for the very constructive discussions over the past weeks.”

Strengthening the Occitanie Sovereign Digital Backbone
By integrating Eurofiber’s assets with its existing sites in Toulouse and Montpellier, ETIX will establish a seamless, carrier-neutral network across the entire of Occitanie. This expansion reinforces ETIX’s commitment to the Toulouse industrial core, specifically designed to empower the Defense and Aerospace sectors while providing a high-performance platform for the regional tech ecosystem. To address the rigorous regulatory requirements of these industries, ETIX provides a fully French-sovereign environment backed by ISO 27001, HDS, and SecNumCloud-ready standards.
Today, ETIX’s network of 19 interconnected sites offers a unique combination of local proximity and national resilience that remains unrivalled.

Densifying the Toulouse Campus: Infrastructure Built for Scale
ETIX is consolidating its leadership in Toulouse by evolving its local assets into a unified campus. Building on the momentum of its 2024 market entry via the zColo acquisition, ETIX is now adding three further sites through the Eurofiber deal to establish a four-site strategic campus.

“Expanding from 15 to 19 datacenters globally marks a defining milestone in ETIX's commitment to delivering truly global coverage for our customers. But the real strategic weight of this acquisition lies in what it opens up in Toulouse. By adding the region's primary interconnection node to our portfolio, we are now ideally positioned to serve one of France's most dynamic Tier 2 markets — alongside Lille and Lyon — cities that are firmly establishing themselves as credible alternatives to Paris and Marseille. Toulouse has the industrial fabric, the talent pool, the connectivity, and now the sovereign infrastructure its ambition requires. We extend a warm welcome to the teams and customers of Eurofiber’s colocation business into the ETIX family, and we are fully committed to elevating the standard of service across every site we operate” said Louis Blanchot, CEO, ETIX

“Eurofiber is a European provider of digital infrastructure with a clear growth strategy focused on open-access fiber networks and integrated digital infrastructure services. As part of this strategy, Eurofiber France will divest its French colocation activities, whose scale was not sufficient to be structurally competitive on a standalone basis. While colocation remains an important component of Eurofiber’s overall strategy, the French market required a different approach. With the transaction, Eurofiber will strengthen its market position and increase its execution capabilities through a strategic partnership with ETIX that enables us to provide our customers with enhanced datacenter capabilities, complementing our digital infrastructure offering in France. Together with ETIX, we are ensuring continuity, reinforced expertise, and an unchanged commitment to delivering high-quality digital infrastructure solutions to our customers. In the Netherlands, Eurofiber continues to operate its own datacenter footprint, where scale and market position support a fully integrated infrastructure model.” said Pierre Cassier, CEO France, Eurofiber

Unifiber was created in 2021 by Eurofiber and Proximus to accelerate the rollout of fiber-to-the-home infrastructure in medium-density areas in Wallonia. Since its inception, the joint venture has made substantial progress, with the rollout well on schedule and approximately 230,000 homes and businesses now passed out of more than 300,000 living units. 

From the outset, Eurofiber’s role in the joint venture was to support the development of a high-quality, open-access fiber-to-the-home network and, over time, transfer its stake. With the network rollout well advanced and Unifiber performing strongly, Eurofiber considers this a natural moment to complete that transition. 

Eurofiber will continue to offer connectivity services to its customers over the Unifiber network, ensuring continuity for business clients and partners. The open-access nature of the network remains unchanged, allowing service providers to benefit from a high-quality, neutral infrastructure. 

About Unifiber
Unifiber is an open-access fiber network operator focused on deploying fiber-to-the-home infrastructure in Wallonia. The company was established in 2021 as a joint venture between Proximus and Eurofiber.  

When Antin Infrastructure Partners acquired Eurofiber as part of its Flagship Fund II, the company operated mainly in the Netherlands, had revenues of about €130 million, a fiber-optic network of 18,000 km and about 3,000 customers. Over the past 10 years, with Antin’s support, Eurofiber has more than doubled its revenues to over 300 million euros at end-2024, operates in 4 countries, has grown its fiber optic network four-fold to more than 76,000 kilometers and tripled its customer base to about 9,000 customers. In the Netherlands, Eurofiber has become the leading B2B connectivity provider.

“We were attracted from the start by Eurofiber’s stellar track-record, talented management team and strong growth potential, as well as by the fact that they viewed their business with an infrastructure mindset,” says Stéphane Ifker, Managing Partner of Antin Infrastructure Partners. “We shared their vision of expanding the company's presence into multiple markets, anticipating the increasing demand for open access networks and the expected internationalization of the industry, and we’re very pleased to see that one decade on, this ambition has clearly been realized.”

Eurofiber quickly got down to business after Antin’s entry, combining both organic growth and acquisitions, with more than €1.5 billion of capital expenditure deployed into the Eurofiber network to grow it by some 58,000 kilometers. Expansion started with the acquisition of B-Telecom in 2015, adding 7,500km network and nationwide coverage in Belgium. A year later, Eurofiber acquired Dataplace to complement dark and lit connectivity offering with regional edge co-location. Today, the Eurofiber Cloud Infra business unit comprises of 11 sites with a total capacity of 24MW across the Netherlands and France, providing (hybrid) cloud infrastructure services including liquid cooling and high-performance computing (HPC) capabilities in select sites.

In 2019, Eurofiber and Antin crossed new borders again with the acquisition of three companies in Northern France, Eurafibre, Eura DC and ATE, laying the foundations for the creation of a nationwide platform targeting 25 metro areas by the end of 2025. At the same time, a dedicated International Business Unit was established to serve global carriers and hyperscalers, addressing their cross-border connectivity needs.

In 2020, joint ventures in Belgium (Unifiber, with Proximus) and Berlin (Eurofiber Netz, initially Vattenfall-Eurofiber) led to the successful deployment of wholesale Fibre-to-the-Home networks. These initiatives have created a footprint of approximately 360,000 homes passed to date, with more than 15 ISPs, including Proximus, 1&1, Telefónica, Pÿur, and Vodafone. The overall future target is to reach around 1.1 million homes passed. 
Also in 2020, Eurofiber welcomed Dutch pension investor PGGM alongside Antin, which renewed its commitment as majority shareholder.

In 2021, Eurofiber further expanded its presence in Germany through a partnership with NGN, adding another 19,000 km to its pan-European network.

 “The strength of our partnership lies in our shared vision of the vital role that open access digital infrastructure plays in the economy and society,” says Alex Goldblum.

Additionally, Eurofiber has established itself as a leader in sustainability, achieving a Platinum EcoVadis rating in 2024, which places it in the top 1% of all companies assessed globally. Eurofiber has also made a public commitment to long-term decarbonization by formalizing a science-based target, approved by the Science Based Targets Initiative (SBTi), to achieve net zero emissions across all scopes by 2040.

Recognizing the vital importance of quantum secure networks for the resilience of our digital society, Eurofiber has been at the forefront of innovation, designing and building quantum communication links and proposing Quantum Key Distribution (QKD) networks. This commitment to innovation has resulted in operational quantum networks in locations such as the Port of Rotterdam. Eurofiber's innovation capabilities have been acknowledged through several prestigious awards, including IT Infrastructure Innovator of the Year 2022 (Data News, Belgium), Networking & Edge Innovator of the Year 2025 (Dutch IT Channel), and runner-up CyberSec Europe Award 2025.

“Innovation and sustainability are ingrained into how Eurofiber runs its business,” says Antin Senior Partner Simon Soder. “Eurofiber’s infrastructure is a critical enabler for its customers when it comes to adoption of technologies such as AI and quantum computing, and at the same time fiber is also a more energy-efficient form of connectivity than the alternatives.”

In 2024, Eurofiber further deployed its fiberoptic network, invested in two additional datacenters and invested more than € 200 million in capital expenditures. The Group’s operational cash flows were strongly positive, allowing for reinvestment in its fiberoptic infrastructure to meet growing customer demand.
