PJSC Rosneft Oil Company (Russian: Росне́фть, tr. Rosnéft', IPA: [ˌrosˈnʲeftʲ] stylized as ROSNEFT) is a Russian integrated energy company headquartered in Moscow. Rosneft specializes in the exploration, extraction, production, refining, transport, and sale of petroleum, natural gas, and petroleum products. The company is controlled by the Russian government through the Rosneftegaz holding company. Its name is a portmanteau of the Russian words Rossiyskaya neft (Russian: Российская нефть, lit. 'Russian oil'). Rosneft was founded in 1993 as a state enterprise and then incorporated in 1995, acquiring a number of state-controlled gas and oil assets. It became Russia's leading oil company after purchasing assets of the former oil company Yukos at state-run auctions. After acquiring OJSC TNK-BP in 2013, then one of the largest oil companies of Russia, Rosneft became the world's largest publicly traded petroleum company. Rosneft is the third largest Russian company and the second-largest state-controlled company (after Gazprom) in Russia in terms of revenue (₽4,134 billion). Internationally, it is one of the largest oil companies, ranking 24 in terms of revenue. In the 2020 Forbes Global 2000, Rosneft was ranked as the 53rd-largest public company in the world. The company operates in more than twenty countries around the world.
