Saudi Aramco is primed to float on international markets to complement a planned primary listing at home, the oil giants chief executive Amin Nasser said on Tuesday. Aramcos initial public offering (IPO) would happen "very soon", Nasser cited Saudi Arabias new energy minister Prince Abdulaziz bin Salman as saying, adding that the final decision on the venue and timing rested with the government. "We have always said that Aramco is ready whenever the shareholder makes a decision to list ... so we are prepared, thats the bottom line," Nasser told reporters, adding: "It is going to be the primary listing, to list locally, but we are ready also for listing outside in other jurisdictions." Saudi Arabia now plans a gradual listing of the worlds top oil producing company on its home market, sources familiar with the matter said. Nasser welcomed the appointment this month of the head of the Kingdoms sovereign wealth fund PIF as Aramcos new chairman, Yasser al-Rumayyan, saying he brought "a lot of riches". Rumayyan took over from former energy minister Khalid al-Falih in a move to separate Aramco from the ministry, a step Saudi officials have said was important to pave the way for the IPO. Nasser spoke to reporters at the World Energy Congress in Abu Dhabi on Tuesday.
