Telekom Srbija’s M:tel has grown into the country’s largest mobile operator, but Montenegro has avoided the dominance seen in neighbouring Serbia. Instead, Deutsche Telekom, Telekom Srbija and Hungary’s 4iG are competing in a small but unusually valuable market that could eventually attract Gulf capital.
Montenegro’s telecommunications market is small enough to be overlooked on a European map, yet its ownership structure increasingly resembles a contest between regional capital blocs rather than three local operators.
The country’s principal telecom companies ultimately sit within Telekom Srbija, Deutsche Telekom and Hungary’s 4iG. Each has access to a parent balance sheet, international procurement and technology partnerships that dwarf the Montenegrin economy. Competition for fewer than one million permanent residents and businesses has consequently become part of a much larger struggle for position across south-east Europe.
The strongest change has come from M:tel, controlled by Telekom Srbija through its regional structure. Having entered Montenegro in 2007, the company has moved from challenger to market leader in mobile communications while building substantial positions in broadband, television and fixed services.
At the end of 2025, M:tel accounted for about 41.4 per cent of mobile subscriptions, compared with approximately 36.2 per cent for Crnogorski Telekom and 22.5 per cent for One Montenegro. Montenegro had roughly 1.48mn mobile connections, putting penetration at around 240 per cent.
The figure says as much about the structure of the Montenegrin economy as it does about telecommunications. Multiple SIM ownership is common, while a tourism industry supporting millions of annual visitor stays creates a population of telecom users considerably larger than the country’s resident base during the summer.
This makes Montenegro an unusual infrastructure market. Its permanent population is only a little above 600,000, but operators must build networks capable of absorbing seasonal demand concentrated around Podgorica and the Adriatic coast. Roaming, prepaid services and increasingly data-intensive tourism raise the economic value of infrastructure beyond what population figures alone would suggest.
M:tel has capitalised on that dynamic aggressively.
Available company figures indicate revenue of approximately €183mn in 2025, with reported EBITDA of around €82mn. Accounting definitions require caution when comparing those figures directly with competitors, but the implied operating profitability nevertheless illustrates the value Telekom Srbija has created in Montenegro.
That also makes M:tel important to the wider debate surrounding Telekom Srbija’s capital structure.
The Serbian parent has spent years expanding through network investment, content, acquisitions and regional diversification while increasingly relying on international debt markets. Its approximately $900mn international bond issue in 2024 was followed by a roughly €1.95bn-equivalent transaction in 2026. The expansion has created a much larger regional telecommunications business, but also a balance sheet that leaves equity capital increasingly relevant to its next phase.
Montenegro improves that equity story.
An investor entering Telekom Srbija would not simply be purchasing exposure to Serbia’s highly concentrated telecom market. It would gain indirect exposure to M:tel Montenegro, operations in Bosnia and Herzegovina and a wider collection of media, content and diaspora businesses.
For a Gulf sovereign or strategic investor, that distinction is important. A regional platform is considerably easier to justify than an isolated investment in a country with barely 600,000 inhabitants.
Montenegro also brings something Serbia cannot: euro-denominated operating exposure.
The country uses the euro despite remaining outside the EU. Revenues from mobile contracts, broadband subscriptions and television services are consequently generated in the same currency in which much of the European telecom industry’s equipment, infrastructure and financing is priced. For an international infrastructure investor, that removes a layer of currency risk that would otherwise have to be incorporated into valuation.
Yet Montenegro is not simply an extension of Telekom Srbija’s dominance at home.
The competitive structure is markedly different.
Crnogorski Telekom remains a formidable incumbent, particularly in fixed infrastructure. Its majority owner, HT Holding, is part of Hrvatski Telekom and therefore ultimately connected to Deutsche Telekom. The German group consequently has an indirect strategic position in one of Montenegro’s most important infrastructure businesses.
Crnogorski Telekom generated approximately €93.4mn of revenue in 2025, with adjusted EBITDA after leases of around €33.7mn and net profit of approximately €7.7mn. Capital expenditure remained close to €18mn, following roughly €20mn the previous year, as fibre and mobile-network investment continued.
The company retains particular strength in traditional fixed telephony, where its market share has remained above half of connections. M:tel has nevertheless closed much of the gap and has established itself as the second major fixed operator.
That creates an increasingly clear two-pole infrastructure market: Deutsche Telekom-backed Crnogorski Telekom against Telekom Srbija-backed M:tel.
The mobile market introduces a third force.
One Montenegro is controlled by 4iG, the Hungarian technology and telecommunications group that has assembled an increasingly important portfolio across central and south-east Europe. The former Telenor operation generated approximately €70mn of revenue in 2025, with EBITDA of around €13mn according to available company figures.
One’s market share is substantially below those of M:tel and Crnogorski Telekom, but its strategic significance exceeds its current scale. 4iG has demonstrated ambitions extending beyond conventional mobile telecommunications into digital infrastructure, IT, satellite communications and defence technology. Montenegro therefore forms part of a broader Hungarian regional investment strategy rather than operating as a standalone financial asset.
The consequence is that Montenegro has effectively internationalised its telecommunications sector without formally constructing a single dominant national champion.
M:tel brings Serbian state-controlled capital. Crnogorski Telekom brings Deutsche Telekom’s European industrial structure. One brings Hungarian strategic capital.
The balance between those groups has so far produced a competitive market. But it also raises the possibility that the next stage of development will be determined less by subscriber acquisition than by access to capital.
Fibre, 5G, cloud infrastructure, cybersecurity, data centres and enterprise digital services require increasingly large investment relative to the size of the underlying consumer market. Operators can no longer assess returns solely through monthly mobile subscriptions. Networks are becoming platforms for corporate IT, government digitalisation and data-intensive services.
That is where Gulf capital becomes relevant.
Abu Dhabi’s e& has already established that telecommunications in central and eastern Europe falls within its strategic investment universe. Its partnership with PPF created exposure to operators in Serbia, Bulgaria, Hungary and Slovakia, while the subsequent acquisition of SBB’s Serbian telecom operations deepened its commitment to the western Balkans.
There is no disclosed process suggesting that e&, another Gulf telecom operator or a sovereign fund is preparing to acquire a Montenegrin operator. The existing regional transactions nevertheless establish an important precedent: Gulf capital is already willing to pay substantial sums for Balkan telecommunications infrastructure when the assets can be incorporated into a larger platform.
A direct acquisition in Montenegro would be more difficult.
M:tel is strategically integrated with Telekom Srbija. Crnogorski Telekom belongs within the Deutsche Telekom-Hrvatski Telekom structure. One sits inside 4iG’s regional strategy. None appears to be an obvious standalone seller.
The more plausible route would therefore be through parent-level equity or infrastructure partnerships.
For Telekom Srbija, this is particularly relevant.
A Gulf sovereign fund or strategic investor acquiring a minority stake at parent level would automatically obtain economic exposure to M:tel Montenegro without dismantling the regional structure. Telekom Srbija could receive permanent capital for deleveraging and further network investment while retaining control of an asset that has taken almost two decades to build.
The structure would also be politically easier than selling M:tel directly.
Montenegro has become one of Telekom Srbija’s most successful regional markets. A disposal would produce immediate cash but remove a profitable euro-denominated business from the group. Parent-level equity could achieve much of the balance-sheet benefit while preserving the operating network.
There is already a precedent for separating infrastructure without selling the customer business.
Telekom Srbija’s tower transaction with an Actis-led consortium transferred approximately 1,800 telecom towers across Serbia, Bosnia and Herzegovina and Montenegro to an independent infrastructure platform. Around 107 sites were located in Montenegro. Telekom remained the anchor tenant under long-term arrangements.
The transaction illustrates a financing model likely to become increasingly relevant across the region.
Passive infrastructure does not necessarily need to sit on the balance sheet of the consumer telecom operator. Towers, fibre networks, data centres and other digital assets can be separated into infrastructure vehicles supported by long-term contracts from the operators using them.
That model is particularly compatible with Gulf infrastructure capital.
Sovereign wealth funds and Gulf-backed infrastructure investors have become major owners of digital assets globally because telecom infrastructure combines long asset lives with relatively predictable cash flows. Montenegro offers the additional advantages of euro revenues, growing data consumption, tourism-driven network utilisation and relatively limited infrastructure duplication.
A fibre or data-centre platform would therefore present a different investment proposition from buying M:tel itself.
The customer-facing operator carries competitive, marketing and regulatory risk. Infrastructure can instead generate contracted revenues from several tenants. Separating those risks can lower the cost of capital and allow telecom operators to continue investing without carrying the entire infrastructure requirement themselves.
Montenegro’s banking system adds another dimension.
Domestic banks are liquid and profitable, but the system is small relative to the financing requirements of multinational telecommunications groups. The country’s operators therefore benefit disproportionately from their parents’ ability to raise capital internationally.
M:tel effectively accesses the financing capability of Telekom Srbija. Crnogorski Telekom sits within the Deutsche Telekom ecosystem. One can draw on 4iG’s regional capital structure.
The competition taking place in Montenegro is consequently as much financial as technological.
An operator capable of accepting a longer fibre payback period can take market share from one constrained by short-term cash generation. A parent capable of funding spectrum and 5G investment without immediately increasing consumer prices has a strategic advantage. Content rights, customer subsidies and bundled packages similarly depend on balance-sheet capacity.
M:tel’s rise demonstrates the importance of that financial backing. Telekom Srbija did not inherit Montenegro’s incumbent network. It entered as a challenger and progressively built scale against an operator linked to one of Europe’s largest telecom groups.
The result is now an asset with more than 40 per cent of mobile subscriptions and substantial fixed-market exposure.
That success also changes the way Telekom Srbija itself should be valued.
Its domestic Serbian position remains the largest contributor to group earnings and the principal source of political and regulatory sensitivity. But an investor assessing Telekom Srbija only as Serbia’s state-controlled incumbent would increasingly miss the regional business being constructed around it.
Montenegro contributes geographic diversification, euro revenues and strong operating economics. Bosnia and Herzegovina adds another substantial telecom franchise. International television and diaspora services broaden the addressable market further.
Telekom Srbija is gradually becoming less like a conventional national incumbent and more like a western Balkan telecom and media holding company.
Its capital structure has not yet fully caught up with that transformation.
Banks and bond investors financed much of the transition. International debt markets demonstrated considerable appetite for the company’s securities, but the cost of that funding remains material. As fibre, 5G, cloud and digital infrastructure demand further investment, another cycle funded principally by debt becomes progressively less attractive.
Permanent capital would change that equation.
A minority Gulf investor at Telekom Srbija level could provide balance-sheet capacity without requiring Serbia to surrender control. M:tel Montenegro would form one of the strongest supporting assets for such a transaction: a profitable operation, a leading mobile position, euro cash flows and exposure to an economy whose tourism sector gives the telecom market a scale beyond its resident population.
Montenegro therefore does not reproduce Serbia’s telecommunications concentration. It reveals something different about the region.
The country’s three main operators are already extensions of larger international capital structures, and their ability to compete increasingly depends on those structures. Telekom Srbija, Deutsche Telekom and 4iG have effectively turned a small Adriatic market into a testing ground for regional telecom strategies.
Gulf capital would represent a fourth layer rather than a replacement for that system. Its most credible entry would be through the infrastructure beneath the operators or through the regional parent companies above them. In Telekom Srbija’s case, M:tel gives such an investor something particularly valuable: exposure to a market where the Serbian group has already proved that expansion beyond its home-country dominance can create a commercially powerful business.
