Entity

INA-Industrija nafte, d.d. is a Croatian multinational oil company structured as a stock company (dioničko društvo) with its headquarters in Zagreb. The company was established on December 31, 1963 (not January 1, 1964) through the merger of Naftaplin (oil and gas exploration and production company) with refineries in Rijeka and Sisak. INA became a state-owned company in 1990 and transformed into a joint stock company in 1993.

The current ownership structure consists of three shareholder categories: MOL Nyrt. holds 4,908,207 shares (49.08%), the Government of the Republic of Croatia holds 4,483,552 shares (44.84%), and institutional and private investors hold 608,241 shares (6.08%). MOL acquired its strategic position through a competitive privatization process that began in 2002, winning the tender with a bid of $505 million for an initial 25% plus one share stake, and subsequently increased its holdings to 49.08% by 2011 through additional share purchases from minority shareholders.

INA Group maintains a leading position in Croatia's oil business with strong regional presence across oil and gas exploration and production, oil refining, and distribution of oil products. The Group comprises several affiliated companies wholly or partially owned by INA, d.d., and as of December 31, 2021, employed 9,655 people.

INA-Industrija nafte d.d. operates two refineries in Croatia: the primary facility in Rijeka and a secondary site in Sisak. The company, which is majority-owned by Hungarian MOL Group (49.08%) with the Croatian Government holding 44.84%, represents the leading oil and gas enterprise in Croatia with significant regional operations.​

INA's core markets are Croatia and Bosnia and Herzegovina, with additional exports to Slovenia, Serbia, Albania, Hungary, and Mediterranean markets. The company operates a regional network of 445 petrol stations across Croatia and neighboring countries. The refining operations aim to secure reliable supply to domestic and regional markets while improving profitability, operational efficiency, and energy security through enhanced conversion capabilities and reduced import dependence.
