Net sales rose by 26 percent to 2.2 billion euros, mainly due to higher oil prices, the company said in a statement on Friday.

"In Slovenia and Croatia the economic conditions are improving, while other countries in southeastern Europe, where Petrol is present, are still facing difficult economic conditions, low purchasing power and high unemployment," it added.

Petrol operates 490 filling stations in Slovenia, Croatia, Serbia, Bosnia, Montenegro and Kosovo. Sales of oil products increased by 7 percent year-on-year when measured in tons.
