YPF S.A. is a vertically integrated, majority state-owned Argentine energy company, engaged in oil and gas exploration and production, and the transportation, refining, and marketing of gas and petroleum products. In the 2020 Forbes Global 2000, YPF was ranked as the 1360th -largest public company in the world. Founded in 1922 under President Hipólito Yrigoyen's administration, YPF was the first oil company established as a state enterprise outside of the Soviet Union, and the first state oil company to become vertically integrated. YPF's first director was Enrique Mosconi, who took up his charge in 1922, remaining there until 1930. During his run on the company, Mosconi advocated economic independence and starting in 1928, nationalization of oil supplies; the latter, however, was never achieved due to a 1930 military coup against Yrigoyen backed by, among others, foreign oil interests. YPF was privatized under president Carlos Menem and was bought by the Spanish firm Repsol in 1999; the resulting merged company was called Repsol YPF. The renationalization of 51% of the firm was initiated in 2012 by President Cristina Fernández de Kirchner. Wikipedia
