Deutsche Telekom has agreed to acquire Polish fibre-network owner Fiberhost and broadband provider INEA at an enterprise valuation of about €1 billion, giving T-Mobile Polska direct ownership of a substantial fixed-line infrastructure footprint. The deal would add a fibre network passing more than 1.4 million homes alongside INEA’s customer base of more than 300,000, subject to approval from Polish competition authorities. It pushes T-Mobile Polska further from its mobile origins towards the converged fixed-and-mobile model already established by several large European telecoms groups.

Fiberhost operates an open-access network, allowing multiple internet service providers to use the same physical infrastructure, while INEA sells broadband and television services to end customers. T-Mobile Polska has been expanding its fixed broadband offer through wholesale agreements since 2018, but ownership of Fiberhost would give the operator a different degree of control over a portion of the network underneath those services. Deutsche Telekom says Fiberhost will continue to provide transparent and non-discriminatory access to existing and prospective wholesale customers after the transaction.

The assets have a footprint that reaches well beyond Poland’s largest cities. Macquarie Asset Management, which is selling the businesses alongside minority shareholders, says Fiberhost has grown from roughly 500,000 homes passed to 1.4 million across eight of Poland’s 16 regions and more than 9,700 towns and villages. Around 60% of the footprint is rural, while the network also connects approximately 3,000 schools, giving the transaction an infrastructure dimension that extends beyond T-Mobile Polska’s ability to bundle mobile and home broadband contracts.

That expansion was supported partly through the EU’s Digital Poland programme as well as private investment, illustrating how publicly backed fibre deployment can eventually become part of larger commercial infrastructure portfolios. Macquarie says 83.1% of Polish households were within reach of fibre by September 2025, above the European average cited in its deal announcement, while the European Commission continues to place gigabit connectivity at the centre of Poland’s digital-development plans. The market is therefore moving from the basic challenge of laying fibre towards questions about ownership, wholesale access, and how operators monetise networks once coverage becomes widespread.

Convergence changes the economics

For T-Mobile Polska, owning fibre creates options that wholesale access alone cannot fully reproduce. A mobile-led operator buying capacity from third-party networks can offer converged services, but the margin on the fixed connection, the pace of network upgrades, and decisions about where to invest remain partly outside its control. Bringing Fiberhost and INEA into the group allows Deutsche Telekom to combine mobile spectrum, backbone infrastructure, data centres, retail broadband customers, and local access fibre within a single Polish operation.

That model can improve the economics of customer retention because households buying several services from one supplier are generally harder to lose than single-product customers, while the operator can spread sales, billing, support, and marketing costs across a broader relationship. Fibre ownership also gives a telecoms group a long-lived physical asset beneath services that can change much more quickly, from conventional broadband and television to cloud access, business connectivity, edge services, and other high-bandwidth applications. The trade-off is that network ownership brings maintenance, capital expenditure, and regulatory obligations that wholesale buyers can partly avoid.

Fiberhost’s open-access status makes that balance more complicated because Deutsche Telekom will potentially own infrastructure that rival service providers depend upon while its T-Mobile subsidiary competes for retail customers. The company’s commitment to continue transparent and non-discriminatory wholesale access will therefore sit near the centre of the regulatory and competitive assessment. Open-access fibre only works as intended when retail competitors can have confidence that the network owner will not use control of pricing, service levels, provisioning, or investment priorities to favour an affiliated provider.

Polish fibre enters a consolidation phase

Poland’s fibre buildout has been shaped by a mixture of commercial investment, specialist infrastructure owners, and public support directed towards areas that were harder to justify through conventional urban economics. Fiberhost’s rural footprint reflects that history, with Macquarie describing eight years of expansion through the pandemic, disrupted equipment markets, and inflation. A €1 billion sale to one of Europe’s largest telecoms groups suggests that some of those networks are now mature enough to attract buyers seeking strategic control rather than purely financial exposure.

The acquisition also follows a wider European pattern in which distinctions between infrastructure owner, wholesale provider, and retail telecoms operator have become more fluid. Fibre networks require large upfront capital commitments and can support multiple service providers over decades, which encouraged specialist infrastructure vehicles and open-access models during the buildout phase. Once coverage improves, vertically integrated telecoms groups have a reason to reconsider whether renting access remains more attractive than owning assets that can support broadband, enterprise services, and mobile-network backhaul.

Polish competition approval remains the immediate condition before Deutsche Telekom can complete the transaction, and the treatment of Fiberhost’s wholesale customers will be one of the practical issues to watch if it closes. T-Mobile Polska would emerge with a substantially larger owned fixed-network base and an established retail broadband business, while rival providers would continue relying on Fiberhost as an open-access platform. The transaction will therefore test whether Poland’s increasingly mature broadband infrastructure can consolidate without weakening the wholesale competition that helped extend fibre beyond the easiest commercial markets.
