The telecommunications sector remained one of the most financially resilient and cash-generative segments of the Serbian economy in 2025, combining stable recurring revenues with scale-driven profitability that few other sectors could match. Even as capital expenditure requirements stayed elevated due to network modernisation, operators preserved strong margins and cash flow dominance, reinforcing telecoms as a structural pillar of domestic value creation.
Market control continued to rest with a small number of large operators. Telekom Srbija, despite partial state ownership, operates within an international financing and partnership framework and remains structurally comparable to foreign-owned peers. Alongside it, Yettel Serbia and A1 Serbia dominated mobile, broadband and data services, collectively accounting for the vast majority of sector revenues, subscribers and investment spending.
Financial performance in 2025 again confirmed telecoms’ exceptional profitability profile. EBITDA margins across leading operators remained consistently above 40 percent, with some mobile-centric portfolios approaching 45 percent on a normalised basis. These margins were sustained by high network utilisation, disciplined pricing strategies and the continued shift of consumption toward data-heavy services. Subscription-based billing models delivered predictable monthly cash inflows, insulating the sector from seasonality and short-term demand shocks.
Revenue growth during the year was steady rather than explosive, estimated at 4–6 percent year-on-year. With market penetration already high, growth was driven primarily by rising average revenue per user rather than new subscriber acquisition. Mobile data traffic volumes increased by 20–25 percent, reflecting higher video consumption, streaming and remote work usage, while fixed broadband customers continued migrating from legacy copper networks to fibre connections with higher pricing tiers.
Capital expenditure remained heavy and strategically focused. Operators continued large-scale investments in fibre rollout, 5G deployment and core network upgrades. Sector-wide capex in 2025 is estimated at €500–600 million, equivalent to roughly 20–25 percent of annual revenues. These investments were essential to maintain service quality, meet regulatory standards and secure long-term competitive positioning. Despite this intensity, free cash flow remained robust due to high EBITDA conversion and efficient working capital management.
The rollout of 5G infrastructure became a central investment theme. Operators accelerated base station upgrades and network densification, particularly in major urban areas and along key transport corridors. While direct monetisation of 5G remained gradual, early enterprise use cases in logistics, industrial connectivity and smart infrastructure began contributing incremental revenues. Fibre deployment followed a similar logic, locking in customers over long asset lifecycles and reducing churn risk.
Balance-sheet strength remained a defining advantage. Foreign-owned operators benefited from access to parent-group funding, keeping effective financing costs in the 4–6 percent range despite tighter global credit conditions. Debt service ratios remained comfortable, supported by predictable cash flows and long-lived infrastructure assets. Telekom Srbija continued to balance domestic investment obligations with external financing, maintaining liquidity while funding network expansion.
Cost pressures increased modestly in 2025. Energy consumption, network maintenance and skilled labour all became more expensive, with personnel costs rising by 7–9 percent due to competition for specialised engineers and IT staff. However, these pressures were largely absorbed through scale efficiencies, automation and selective price adjustments, leaving overall margin structures intact.
Regulatory compliance costs also rose, particularly in areas such as data protection, cybersecurity and EU-aligned telecom standards. While these requirements added to operating expenses, they also reinforced barriers to entry and protected incumbent market positions. Spectrum fees and regulatory charges remained predictable, allowing operators to plan multi-year investment cycles with relatively low regulatory risk compared with sectors exposed to commodity or geopolitical volatility.
From a macroeconomic perspective, telecoms in 2025 continued to act as a stabilising force. High margins, recurring revenues and sustained investment translated into reliable tax payments, dividend capacity and employment stability. Unlike export-oriented sectors, telecommunications generate value almost entirely from domestic demand, yet do so with efficiency levels comparable to international benchmarks.
By the end of 2025, Serbia’s telecommunications sector had clearly transitioned from expansion-driven growth to capacity- and quality-driven growth. Subscriber numbers mattered less than data intensity, network performance and enterprise connectivity. Financially, this model continued to deliver strong cash generation despite heavy capital commitments, making telecommunications one of the few sectors in Serbia where sustained investment and sustained profitability coexist without structural tension.
