Hungarian technology group 4iG is assessing investment opportunities in Montenegro’s renewable energy, electricity networks, energy supply and digital infrastructure, expanding its potential activities beyond telecommunications as negotiations advance over a state data centre. The Budapest-listed company said it was reviewing business opportunities in Montenegro as part of its broader expansion into the energy sector across Central and Eastern Europe and the Western Balkans. Potential activities in Montenegro include renewable power generation as well as related grid, energy-supply and digital-infrastructure solutions.
4iG selected for state technology projects
4iG has operated in Montenegro through mobile operator One Montenegro since 2021. In March, Montenegro’s government selected 4iG Group for negotiations concerning the construction of a state data centre and a separate technology-modernisation programme for law-enforcement agencies. The law-enforcement programme has a planned budget of €54.25 million, while the data centre’s cost and financing structure have not yet been established.
4iG said its international digital-infrastructure subsidiary would develop the data centre to Tier III certification standards. The company’s March stock-exchange disclosure stated that Montenegro had decided to enter negotiations with 4iG and its subsidiaries, while noting that the government decisions did not constitute a contractual commitment.
Projects based on Montenegro-Hungary agreement
The planned projects originate from an intergovernmental cooperation agreement signed by Montenegro and Hungary in July 2025. The agreement covers infrastructure development, telecommunications and information technology.
The proposed data centre would expand Montenegro’s state-controlled digital infrastructure as the country develops public-sector digitalisation, cybersecurity and data-management capacity. The next stage depends on whether negotiations result in binding agreements and establish a financing structure for the facility.
Company expanding regional energy activities
4iG said in August that it was establishing a dedicated energy business and evaluating investments across the region. In North Macedonia, the company is considering wind and energy-storage projects with combined capacity exceeding 100 MW.
It has also submitted an offer related to a wind portfolio in Hungary. Separately, 4iG has signed a non-binding agreement with U.S.-based X-energy to examine the potential deployment of small modular nuclear reactor technology in Central and Eastern Europe and the Western Balkans. The scale and timing of any separate 4iG investment in Montenegro’s energy sector have not yet been defined.
First-half revenue reaches 409.4 billion forints
4iG reported consolidated revenue of 409.4 billion forints for the first half of 2026, representing a 16.7% increase from the same period of 2025. Profit after tax reached 21.9 billion forints, compared with a loss recorded in the first half of 2025. Telecommunications remained the company’s largest business segment. In Montenegro, the immediate milestone is the outcome of negotiations over the state data centre and the establishment of any related financing arrangements, while potential investments in renewable energy, power networks, energy supply and digital infrastructure remain under consideration.
