INA (company)

INA (company). INA is a major Central European oil and gas company, headquartered in Zagreb, Croatia. It is a fully integrated company, active in exploration and production, midstream transportation, and refining and marketing. The company is a key subsidiary of the international MOL Group, operating across the Adriatic Sea region and beyond.

History

The company's origins trace back to the establishment of the state-owned Naftaplin in 1949, focusing on hydrocarbon exploration in the Pannonian Basin. In 1964, the Government of Yugoslavia merged several entities to form INA, consolidating the national petroleum industry. Significant early developments included the discovery of major fields like Ivanić Grad and expansion of the Rijeka Oil Refinery. Following the dissolution of Yugoslavia and the Croatian War of Independence, the company was transformed into a joint-stock company owned by the Republic of Croatia. A pivotal moment came in 2003 when the Hungarian energy group MOL Group acquired a strategic stake, leading to a full takeover and integration by 2009, which reshaped the regional energy landscape.

Operations

INA's upstream operations are centered on hydrocarbon exploration and production in Croatia, with significant assets in the Drava and Sava basins, and offshore in the Adriatic Sea near Istria. The company also holds international exploration licenses in Angola, Egypt, and the North Sea. Its midstream activities include managing an extensive network of pipelines and storage facilities, such as the Sisak Oil Refinery terminal. The downstream segment is anchored by two major refineries: the Rijeka Oil Refinery and the Sisak Oil Refinery, which supply the domestic and regional markets. INA operates a vast retail network under the INA brand across Croatia, Bosnia and Herzegovina, and Slovenia.

Products and services

The company's primary refined products include motor gasoline, diesel fuel, heating oil, and jet fuel, produced at its facilities in Rijeka and Sisak. It markets a comprehensive range of lubricants and bitumen for industrial and consumer use. In the natural gas sector, INA is a key supplier within Croatia, contributing to the national grid and supporting the energy security of the Balkans region. The retail segment offers fuels, lubricants, and convenience store items at its service stations, while also providing LPG and electric vehicle charging infrastructure as part of its evolving energy portfolio.

Corporate structure

INA operates as a key subsidiary and the industrial flagship of the MOL Group, one of Central and Eastern Europe's leading integrated oil and gas groups. The corporate governance is led by a Supervisory Board and a Management Board, with the President of the Management Board overseeing daily operations. Major operational divisions are structured into Exploration and Production, Refining and Marketing, and Consumer Services and Logistics segments. The company's shares are listed on the Zagreb Stock Exchange and the London Stock Exchange, with MOL Group holding a controlling interest and the Government of Croatia retaining a significant minority stake.

Environmental and social responsibility

The company has implemented projects to reduce emissions and increase energy efficiency at its Rijeka Oil Refinery and Sisak Oil Refinery sites, aligning with European Union directives. It engages in biodiversity protection programs, particularly for areas surrounding its operations in the Adriatic Sea and the Pannonian Basin.
