Rosneft said its 100 percent subsidiary Neft-Aktiv bought Unitex, which has 495 filling stations and a number of product terminals in European and southern Russia, for 16.3 billion rubles.
Neft-Aktiv also bought more than 100 retail stations from another lot of the Yukos assets for 4.9 billion rubles.
Unitex, a little-known company whose owners have not been disclosed, paid 17.5 billion rubles ($676 million) in auctions that included the assets bought by Rosneft.
The purchase of the filling stations would help Rosneft become a leader in the retail market in Russia, Rosneft said.
"Having added refining capacity lately, and with our desire to expand the downstream business generally, it's clear that it's a very profitable business and will continue to grow, and the margins are attractive," said Peter O'Brien, Rosneft's finance vice president. "And with the new production volumes that we expect over the next few years, it's clear that it fits into the strategy."
On Monday, Rosneft CEO Sergei Bogdanchikov said the company was in talks to buy other assets acquired by the unknown company Prana in an auction in May. Prana beat Rosneft with a $3.9 billion bid for a lot that included Yukos' headquarters.
