Feb 4 (Reuters) - Romanian oil and gas group OMV Petrom ROSNP.BX reported on Wednesday a 41% jump year-on-year in its fourth-quarter adjusted operating profit, driven by stronger refining margins, higher gas and power margins and increased gas sales volumes.
The Bucharest-listed group posted an operating profit adjusted for clean current cost of supply, of 1.35 billion lei ($313.60 million), compared with 955 million lei a year earlier.
The clean operating result, which is based on the current cost of supply, excludes one-off items and short-term gains and losses from energy inventory holdings.
