What’s really driving telecoms consolidation in Europe (and what it means for operators)

Across Europe, the networks carrying work, entertainment and everyday communication are bearing steadily more traffic, even as the economics of building them become harder to reconcile. Connect Europe’s 2026 report records annual fixed-network traffic of 1,104 exabytes in 2025, up from 989 exabytes in 2024, and mobile-network traffic of 169 exabytes, up from 149 exabytes (Eurostat defines fixed and mobile broadband traffic as yearly volumes of uploaded and downloaded data measured at the end-user access point (Eurostat, 2026)). Those increases are approximately 12% and 13%, respectively (Connect Europe and Analysys Mason, 2026).

One national measure offers a more intimate sense of that demand. In Germany, around 175 billion gigabytes crossed fixed networks in 2025, an average of about 376 GB per fixed broadband line per month, while active mobile SIM profiles used an average of 8.4 GB a month (Bundesnetzagentur, 2026). Even though, these are German averages and not European household figures, but they help translate an abstract exabyte into the persistent flow of video, calls, work files, cloud backups and connected devices moving through local networks.

Talking about the mobile networks, they too face a similar distinction between broad coverage and more advanced capability. Connect Europe reports that 5G covered 94.9% of the population in its Europe comparison in 2025, but 5G accounted for 43% of mobile connections and 5G Standalone coverage reached 63% of the population (Connect Europe and Analysys Mason, 2026). A signal on a coverage map is therefore not the same thing as widespread adoption of the more advanced network architecture operators hope to use for lower latency and new enterprise services.

Against that backdrop, telecoms consolidation is back on-board agendas because operators must fund fibre, 5G and resilient core networks while revenue growth remains modest, and national markets remain distinct. Whether fewer operators would lift investment without weakening competition is still contested. (Connect Europe, 2026; BEREC, 2026)

This article separates the structural economics from the evolving policy debate, reviews the evidence both for and against consolidation, and sets out a practical test for determining whether scale is genuinely the right answer to an operator’s strategic problem.

For strategy and investment teams, the practical question is which transaction structure solves a defined business problem, delivers measurable benefits, and withstands competition review.

Key takeaways

• Consolidation pressure is structural, not cyclical.
• The Draghi and Letta reports moved telecom scale and market integration higher up the EU competitiveness agenda.
• The evidence that consolidation raises investment is genuinely contested, and operators should not assume approval follows from the policy’s mood.
• Scale alone does not create value.

Telecoms consolidation is the combination, acquisition or reorganisation of operators and network assets to reduce duplication, increase scale or improve capital efficiency. It may involve direct competitors in one country, businesses in different countries, or infrastructure such as towers, fibre routes, data centres and parts of the access network. These approaches serve different purposes and carry different regulatory implications (European Commission, Draft Merger Guidelines, 2026).

In-market horizontal consolidation brings together operators competing in the same national market, through a full merger or the acquisition and redistribution of customers, spectrum, sites or other assets. Cross-border consolidation combines businesses or portfolios in different countries, with the aim of creating a broader footprint or a more integrated operating model. Infrastructure consolidation pools, separates or reorganises assets, often through a joint venture, NetCo or specialist platform.

An adjacent growth acquisition may matter to an operator’s wider portfolio, but it is not necessarily telecoms consolidation in this sense. Unless it combines network operations, removes duplication or changes the structure of connectivity provision, it does not by itself reduce fragmentation.

The economic pressures behind the present debate are long running. Spectrum, fibre, radio equipment, core systems, security and operational platforms require substantial upfront spending; networks must also be maintained and renewed as traffic grows. In 2023, a Commission-commissioned WIK-Consult model estimated about €114 billion in investment to achieve the fixed gigabit target through FTTP and €33.5 billion for full 5G service. If the networks were deployed independently, the model put the total at about €148 billion, with another €26 billion to €79 billion for major transport routes such as roads, railways and waterways. A parallel deployment scenario produced a lower modeled total of about €120 billion. These are scenario estimates, not a current spending bill, but they illustrate the scale and deployment choices involved (European Commission and WIK-Consult, 2023).

What has changed is the policy setting. European institutions are weighing connectivity investment alongside competition, consumer welfare, resilience, innovation and the ability to operate across borders. Those aims may sometimes reinforce one another, but their relationship must be shown in the facts of each transaction.

How fragmented is the European telecoms market?

Connect Europe’s 2026 report counts 44 mobile network operators with more than 500,000 subscribers in its Europe comparison, alongside more than 70 fibre network operators with over 500,000 premises passed. It reports eight mobile operators above that subscriber threshold in the United States, four each in Japan and China, and three in South Korea; for fibre, it counts 28 operators in the United States, six in Japan, five in South Korea and four in China. These figures are useful indicators of provider structure but Connect Europe’s “Europe” is its own geographic reporting perimeter, not simply the EU27. The report counts providers across that wider area, while many competitive conditions and rules still vary from one national market to another (Connect Europe and Analysys Mason, 2026).

The distinction matters because Europe is not one fully integrated telecoms market. Letta described 27 distinct national electronic communications markets, a structure that affects spectrum licences, regulation, consumer behaviour and the practical operation of cross-border services. The Connect Europe operator counts therefore illustrate a regional landscape; they do not show that any particular country has too many competitors or that a merger there would necessarily improve investment (Letta, 2024).

There is a straightforward economic argument behind the comparison. Radio networks, fibre routes, spectrum rights, core platforms, and cyber-resilience capabilities carry substantial fixed costs. Where customer bases and revenues are split among more providers, each company may have fewer subscribers over which to spread those costs. Greater scale or shared infrastructure could improve capital efficiency, particularly where duplicate assets are costly to maintain, and demand is insufficient to support parallel investment.

But provider counts are not a verdict. Connect Europe represents leading connectivity providers, and its report was prepared by Analysys Mason for the association, so its analysis should be read as an informed industry perspective as well as a market comparison (Connect Europe and Analysys Mason, 2026). The differences between a country with dense cities, one with widely dispersed rural settlements and one with a different spectrum framework cannot be reduced to a single operator count. The stronger conclusion is that Europe remains institutionally and operationally fragmented; whether that fragmentation is the principal cause of an investment shortfall must be tested case by case.

Why is European telecoms ARPU under pressure?

Connect Europe reports GDP-adjusted European mobile ARPU of €14.9 in 2024, down 2.4% year on year and below the €15.3 recorded in 2015. The same report puts 2024 GDP-adjusted ARPU at €26.1 in the United States, €21.7 in South Korea, €21.3 in Japan and €18.3 in China. It also records telecom capex falling 2%, from €65.8 billion in 2023 to €64.6 billion in 2024, and per-capita telecom investment of €118 in Europe compared with €217 in the United States, €173 in Japan and €151 in South Korea (Connect Europe and Analysys Mason, 2026). One needs to consider that ARPU is also an operator’s revenue measure, not a direct comparison of household bills.

The consumer-price picture helps explain why those measures can point in different directions. BEREC’s 2026 fact-finding report finds that EU consumers benefit from some of the lowest broadband prices among the jurisdictions it examined. In its 2022 comparison, the average lowest standalone fixed-broadband offer at speeds of at least 1 Gbps was €35.17 in the EU, compared with €80.08 in the United States. For offers from 200 Mbps to 999 Mbps, the averages were €24.94 and €49.25, respectively (BEREC, 2026). These are averages of the lowest offers in each country, not typical household bills, but they show that lower operator revenue per subscriber can coexist with low prices for customers.

Several forces help explain the pressure on revenue per user. Consumer mobile markets are mature; operators compete on price and bundles, and voice and messaging revenues have given way to data plans. Services may look similar to customers, limiting the ability to charge more for additional capacity, while applications and digital services capture much of the value built on top of connectivity.

At the same time, a low ARPU does not, by itself, demonstrate that operators cannot fund network investment. BEREC’s 2026 analysis reports average return on capital employed for a peer group of 14 European operators at 8.89% in 2023, 10.96% in 2024 and 9.44% in 2025, compared with an estimated global telecom-sector average of about 5% in 2023 (BEREC, 2026). BEREC notes that this aggregate varies among operators and countries, but its findings describe a sector with financial resilience as well as continuing investment needs. The useful question is therefore not whether the pressure is real, but which companies face it, which investments are constrained and whether a particular transaction would resolve those constraints.

The wider European digital communications ecosystem, including telecom services, network equipment, content and applications, was valued at €1.09 trillion in 2024, or about 5% of Europe’s GDP, according to Connect Europe (Connect Europe and Analysys Mason, 2026). That figure includes industries beyond telecom operators themselves; it signals how many parts of the economy depend on connectivity; not how much revenue operators can capture from them.

Low ARPU alongside ongoing network investment is the commercial condition for which consolidation is often proposed as a remedy. It does not, on its own, establish that a merger will unlock investment. Lower prices can be an outcome of vigorous competition, and the test for a specific transaction is whether it creates efficiencies that would not otherwise occur and turns them into better networks, services or value for customers.

How are the EU’s new merger guidelines changing the rules?

As of 8 October 2026, the European Commission’s revised Merger Guidelines remain a draft. The Commission published the draft on 30 April, closed its consultation on 26 June and says it intends to complete the review in the fourth quarter of 2026. The draft itself states that it has not been adopted or endorsed and does not represent an official Commission position. If finalized, it would replace the 2004 Horizontal and 2008 Non-Horizontal Merger Guidelines (European Commission, Draft Merger Guidelines, 2026).

For telecoms parties, one important, proposed change is a fuller treatment of efficiencies through a “theory of benefit.” The draft says parties claiming efficiencies should explain how specific merger efficiencies arise, how they maintain or enhance effective competition, and how they benefit consumers through lower prices, increased output, innovation, choice, quality or investment. It also says that claims should be substantiated with a body of evidence to the same evidentiary standard as the evidence used to assess potential competitive harm (European Commission, Draft Merger Guidelines, 2026).

The draft recognizes that timing depends on the sector. It says that a three-to-four-year horizon has been accepted in past cases in sectors including telecoms, while cautioning that longer periods can make projected benefits harder to predict and quantify. Dynamic investment or innovation may take time to translate into customer benefit, but parties would still need to show how it is likely to happen and how substantial it is (European Commission, Draft Merger Guidelines, 2026).

The proposed “innovation shield” is narrower than its name may suggest. It concerns certain transactions involving small innovative companies, start-ups or research and development projects with competitive potential; it is not a general exemption for mergers between established telecom operators. The draft also examines potential harm to direct competition, investment, innovation, market entry, coordination and customer choice (European Commission, Draft Merger Guidelines, 2026).

The draft gives dealmakers a more developed vocabulary for explaining scale, investment and innovation benefits, but it does not create a presumption that a four-to-three mobile merger will be approved. Its publication has changed the discussion, not the legal status of the draft, or the need to support each transaction with evidence.

What is the Digital Networks Act, and how does it fit?

The Digital Networks Act (DNA) is a European Commission legislative proposal adopted on 21 January 2026. It aims to simplify and harmonize parts of the EU connectivity framework, but it remains subject to the legislative process and is not yet in force. The proposal would bring together four legal acts: the European Electronic Communications Code, the BEREC Regulation, the Radio Spectrum Policy Programme and core parts of the Open Internet Regulation (European Commission, Digital Networks Act, 2026).

Measures relevant to operators seeking a wider footprint include a proposed Single Passport authorization process, under which a provider could notify one Member State when offering services in several EU markets, and more harmonized spectrum arrangements. The proposal also includes longer and renewable spectrum licenses, broader opportunities for spectrum sharing, EU-level authorization for satellite spectrum, and national transition plans for phasing out copper networks in favor of full fiber (European Commission, Digital Networks Act, 2026).

The two policy tracks should be kept distinct. The DNA may make it easier to operate and invest across borders; merger control will still assess whether an individual’s transaction harms competition. A single authorization process and more harmonized rules do not amount to a general license for consolidation.

What does consolidation look like in practice?

The proposed acquisition of SFR by Bouygues Telecom, Orange and the Free-iliad Group shows how consolidation can take the form of a three-way carve-up rather than a conventional merger. On 6 June 2026, the parties signed a memorandum of understanding with Altice France at an enterprise value of €20.35 billion, subject to adjustments, including a potential earn-out of up to €650 million. The memorandum set out a possible closing in the second half of 2027, subject to regulatory approval and other conditions; the parties explicitly said at the time that there was no certainty the transaction would proceed (Bouygues Telecom et al., 2026).

Under the announced terms, Bouygues would contribute about 42% of the price, Iliad 31%, and Orange 27%. The differing proportions show why a transaction headline price split alone cannot explain which assets, customers and business lines each buyer would receive.

The memorandum makes the execution challenge tangible. It allocates 5.9 million SFR consumer customers and 0.5 million Prixtel customers to Bouygues, 6.0 million RED by SFR customers and part of SFR’s consumer base to Iliad, and a portfolio of 4.9 million customers to Orange. The companies describe the migration of millions of subscribers, infrastructure, and systems as a multi-year industrial programme. Some network assets and IT systems would remain in SFR SA, jointly held by the three buyers, for a transition period of at least 30 months (Bouygues Telecom et al., 2026). These are not just terms in a financial model: they describe the operational work needed to maintain service while customers and systems are moved.

The review process has also crossed jurisdictions. On 15 July 2026, the European Commission referred the examination of Iliad’s planned acquisition of certain Altice France assets to the French Competition Authority. The transaction forms part of three distinct but contractually linked deals affecting the same French fixed and mobile markets. The French authority said its experience with the sector and the transactions’ national-market dimension supported its role in the review (Autorité de la concurrence, 2026). The referral shapes the review path; it does not prejudge the outcome.

Does consolidation actually deliver more investment?

The available evidence does not support a universal rule that fewer operators produce more total investment. BEREC’s October 2026 fact-finding report summarizes an EC-commissioned analysis of 29 OECD countries from 2009 to 2019. In one regression, an additional mobile network operator was associated with 7% lower ARPU and 10% higher country-level mobile investment. BEREC also says that other methodological approaches did not show a clear or statistically reliable link between operator count and investment. The figures describe associations across markets, not proof that adding or removing an operator caused the observed result (BEREC, 2026, citing Lear et al., 2024).

BEREC’s summary of post-merger evidence points to a consumer trade-off. Its review of mergers in Austria, Ireland and Germany found evidence of short-to-medium-term price increases even where mobile virtual network operator remedies were in place. BEREC also cites a modeled estimate of around €800 million in annual consumer savings if every EU country had four mobile network operators; that is a counterfactual estimate, not observed savings from a single policy change. The regulator’s wider conclusion is that greater scale does not automatically lead to more investment, innovation, or competitiveness, while greater competition is associated with lower prices (BEREC, 2026).

There is industry-sponsored evidence pointing in the other direction. A 2026 GSMA Intelligence study reports that three-player mobile markets invested about 48% more per connection than four-player markets, and that consolidation events were associated with 28% to 38% higher capex and network speeds about 25% higher. It also describes an inverted-U relationship in which investment and network quality peak at concentration levels above the current European average (GSMA Intelligence, 2026). These findings add evidence to the debate, but they should be read with their source and model in view: GSMA Intelligence is part of an industry association, and its comparisons do not establish that every merger will produce the same result.

A credible assessment should therefore keep separate measures separate total market investment; investment per operator; investment per subscriber; network coverage and quality; consumer prices; and return on invested capital. A transaction can improve one measure while worsening another. Its result depends on the deal structure, market conditions, remedies and whether promised efficiencies become measurable improvements for the people and businesses relying on the network.

What does consolidation mean for operators? Detecon’s view

For operators, the useful principle is precision over scale. A transaction should solve a defined strategic problem, demonstrate measurable financial and operational value, and explain how promised efficiencies will reach customers. In slow-growth markets, a larger footprint is an outcome; it is not, by itself, an investment thesis.

1. First, the deal logic must be specific. The case should identify the capability, market position, or portfolio problem the transaction addresses and distinguish durable benefits from optimism attached to a larger balance sheet. General claims about scale or eventual synergies are difficult to test unless they are tied to assets, processes, customers or investment decisions that the deal will actually change.
2. Second, capital efficiency is central. Operators should explain which synergies are specific to the transaction, how and when they will be realized, what implementation will cost, and how investment will be allocated between renewal and new infrastructure. The metrics should connect spending to outcomes: for example, fiber coverage and take-up, 5G capacity and service quality, resilience, or unit costs.
3. Third, structural complexity can drain value from the original case. Infrastructure carve-outs, legacy IT, regulatory remedies, and overlapping operating models can delay integration. In the SFR memorandum, the parties themselves describe the migration of millions of subscribers and systems as a multi-year program and provide for a shared transition structure lasting at least 30 months (Bouygues Telecom et al., 2026). Network architecture, customer migration, employees, brands and technology integration belong in the transaction thesis from the start, not in a workstream added after signing.

Operators considering consolidation can pressure-test the case through five questions:

1. Strategic fit: What capability, market position or portfolio problem does the transaction solve?
2. Economic case: Which synergies are measurable, specific to the transaction and achievable within a credible timeframe
3. Regulatory case: Which investment, innovation and customer benefits can be evidenced, delivered, and monitored?
4. Structural design: Is a full merger preferable to network sharing, a NetCo, an asset carve-out, infrastructure separation or a cross-border acquisition?
5. Execution readiness: Are the network, IT, brand, customer-migration and organizational requirements understood before signing?

The period before the revised Merger Guidelines are finalized gives operators a reason to build their evidence now: establish a baseline, compare alternative structures, quantify how each option changes investment incentives, and define customer outcomes that can be monitored. Detecon’s “precision over scale” perspective, set out in its Rethinking M&A in Telecom whitepaper, follows the same discipline: begin with the value to be created, then choose the structure most likely to deliver it (Detecon, 2026).

For organizations assessing transaction strategy, operating-model choices or post-merger execution, Detecon’s M&A advisory, regulatory advisory and telecoms consulting teams can support the work from strategic rationale through to implementation.

Conclusion

The structural pressures behind European telecoms consolidation are real. In 2025, annual fixed-network traffic reached 1,104 exabytes, EU FTTP coverage stood at 74.1% of households, and operators continued to face the cost of extending fibre and modernising mobile networks (Connect Europe and Analysys Mason, 2026; European Commission, Connectivity Coverage in Europe 2025, 2026). Yet the evidence does not show that a lower operator’s count, by itself, will resolve those investment needs. BEREC finds that consumer prices are comparatively low and that greater scale does not automatically produce stronger investment or innovation; other studies report benefits under particular market conditions and measures (BEREC, 2026; GSMA Intelligence, 2026).

For operators, the next step is to ask two questions with equal discipline: can the case withstand an evidence-based assessment of investment, efficiency and consumer effects, and is the right answer in-market scale, cross-border expansion, shared infrastructure or structural separation? The opportunity is not simply to become larger, but to identify the arrangement that can create defensible value and deliver it.
