Hungarian technology group 4iG is considering investments in renewable energy, power networks, energy supply and digital infrastructure in Montenegro, widening its presence in the Balkan country beyond telecommunications as it prepares to participate in a government data-centre project.
The Budapest-listed company said it was reviewing business and investment opportunities in Montenegro as part of a broader move into energy across Central and Eastern Europe and the Western Balkans. Potential activities include renewable generation and related grid, energy-supply and digital-infrastructure solutions.
4iG has operated in Montenegro through mobile operator One Montenegro since 2021.
Montenegro’s government in March selected 4iG Group for negotiations covering the construction of a state data centre and a separate technology-modernisation programme for law-enforcement agencies.
The law-enforcement project has a planned budget of €54.25 million, while the cost and financing structure of the data centre have yet to be determined. 4iG said its international digital-infrastructure subsidiary would develop the facility to a Tier III certification standard.
In its March stock-exchange disclosure, 4iG said Montenegro had decided to begin negotiations with the group and its subsidiaries, but stressed that the government decisions did not constitute a contractual commitment.
The projects stem from an intergovernmental cooperation agreement signed by Montenegro and Hungary in July 2025, covering infrastructure development, telecommunications and information technology.
The planned data centre would expand Montenegro’s state-controlled digital infrastructure as the country invests in public-sector digitalisation, cybersecurity and data-management capacity.
4iG said in August that it was establishing a dedicated energy business and examining investments across the region. In North Macedonia, it is considering wind and energy-storage projects exceeding 100 MW, while it has also submitted an offer linked to a wind portfolio in Hungary.
The company has separately signed a non-binding agreement with U.S.-based X-energy to explore deployment of small modular nuclear reactor technology in Central and Eastern Europe and the Western Balkans.
4iG reported consolidated first-half 2026 revenue of 409.4 billion forints, up 16.7% from a year earlier, while profit after tax reached 21.9 billion forints, compared with a loss in the same period of 2025. Telecommunications remained its largest business segment.
The next milestone in Montenegro will be whether negotiations produce binding contracts and a financing structure for the state data centre. The scale and timing of any separate 4iG investment in the country’s energy sector have yet to be defined.
