The consortium filed the only bid in a public auction organized in December 2011.
Transgaz is 73.5%-owned by the Economy Ministry. Romanian investment fund Fondul Proprietatea (FP.RO) has almost 15% of its shares, while the rest is distributed among various shareholders.
Wednesday, Transgaz closed up 0.49% at 235 lei (EUR54.06) a share. At the current price, Romania would raise RON415 million (EUR95.5 million) from the sale, which is slated for launch in the March-April period.
