RIYADH, Nov 28 — The retail portion of Saudi Aramco’s initial public offering (IPO) has been oversubscribed, with orders reaching 38.1 billion Saudi riyals (US$10.2 billion), lead manager Samba Capital said today.

The state oil giant plans to sell a 1.5 per cent stake, or about 3 billion shares, and has said at least one-third of the sale is expected to be covered by retail investors, who have until today to sign up.

With an indicative price of 30-32 riyals, the IPO is valued at as much as 96 billion riyals (US$25.6 billion) and gives the firm a market value of US$1.6-$1.7 trillion.

It will be the world’s biggest IPO if it tops the US$25 billion set by China’s Alibaba in 2014.

Around 4.17 million retail investors had subscribed to 1.19 billion shares by 12 pm on Thursday, injecting 6.13 billion riyals above the amount needed for full coverage, Samba said.

Subscription will continue until midnight on Thursday and final results will be announced tomorrow, it said in a statement.

The IPO is the centrepiece of Crown Prince Mohammed bin Salman’s plans to diversify the Saudi economy away from its reliance on oil.

Aramco is the crown jewel of the economy and the world’s most profitable company.

It is relying on local and regional demand to pull off the deal, after cancelling marketing roadshows outside the Gulf region due to a lack of interest from foreign institutional investors.

Sources told Reuters this week that the sovereign wealth funds of Abu Dhabi and Kuwait plan to invest.

Saudis have been eager to buy shares, with many seeking to invest on behalf of their dependents to increase the number of shares they can buy.

The government has encouraged rich Saudis to invest, with many viewing it as an opportunity to show their patriotism after a September attack on Aramco facilities that struck at the heart of the kingdom’s energy industry.

Washington and Riyadh blamed regional rival Iran for the attacks, which temporarily cut more than 5 per cent of global oil supply. Tehran denied any involvement. — Reuters
