The current profit level is an exceptional situation, likely related to the recent Russia-Ukraine war. If the net income increases proportionally to 3 billion for the whole year, then the average net income over the past 5 years would be 0.5 billion, corresponding to a pe ratio of 11. If the war ends in the next year or two and Russian oil returns to the commodity market, based on the highest net income of 0.48 billion in 2017, the corresponding pe ratio would be 11.5.
