Saudi Aramco has confirmed it is planning to list on the Riyadh stock exchange, in what could be the world's biggest initial public offering (IPO).
The state-owned oil giant will determine the IPO launch price after registering interest from investors.
Business sources say the Saudis are expected to make shares available for 1% or 2% of the firm, and the offer will be for existing company shares.
Saudi Aramco is thought to be worth about $1.2tn (£927bn).
The firm said it has no current plans for a foreign share listing, saying long-discussed plans for a two-stage IPO including an offering on a foreign exchange had been put aside for now.
"For the (international) listing part, we will let you know in due course. So far it's only on Tadawul," Aramco chair Yasir al-Rumayyan told a media conference, referring to the Saudi stock exchange.
Chris Beauchamp, chief market analyst at derivatives traders IG Group, said: "Investing in Aramco carries risks, of course, and not only that oil prices will struggle to move higher.
"Political and strategic risks are high for any firm operating in the region, not least one which is an arm of the Saudi state. Aramco also has limited control in output policy, a key part of Saudi Arabia's Opec management."
Those potential risks were highlighted in September when drone attacks hit the Abqaiq oil facility and the Khurais oil field in Saudi Arabia, both owned by Aramco.
But Aramco boss Amin Nasser, who called the plans "historic", told a media conference after the IPO statement was published that the firm was still the most reliable oil company globally.
In its launch announcement Aramco said: "The company does not expect the impact of these attacks to have a material impact on its business, financial condition or results of operations."
What is Saudi Aramco?
Saudi Aramco traces its roots to 1933 when a deal was struck between Saudi Arabia and the Standard Oil Company of California, which later became Chevron, to survey and drill for oil, creating a new firm to do so.
Between 1973 and 1980, Saudi Arabia bought the whole company.
Saudi Arabia has the second-biggest oil reserves after Venezuela, according to the Energy Information Administration. It is also second in production, after the US. But it gets its prominence because it has the monopoly on all that oil in the country, and because of how cheap it is to extract.
It's essentially the world's largest unquoted company; it's a massive global oil producer," said David Hunter, director of market studies at Schneider Electric.
"This is the absolute mother of all oil and gas companies."
Why is it worth so much money?
Saudi Aramco is worth $1.2tn, according to analysis from financial news service Bloomberg, although Riyadh would prefer a valuation of $2tn, which is one reason the company's share sale has been delayed a number of times.
Mr Beauchamp from IG Group says: "Aramco is a world away from the tech IPOs that have been all the rage lately, but the valuation problem still haunts them like it does the firms of Silicon Valley."
He adds: "$2 trillion probably overstates the worth of the firm in a world of high oil supply and uncertain demand, but $1.2 trillion is too low for a vital part of the Saudi state".
Either way, it is phenomenally profitable. For the first half of 2019, it posted a net profit of $46.9bn, almost all of which was paid out in dividends to the Saudi state. Any company that profitable will attract a high price. By comparison, for the same time period, Apple, the world's largest company by value currently, posted a net profit of $21.6bn, and Exxon Mobil, the largest listed oil company, made $5.5bn.
Another aspect is the cost of production. Whereas extracting North Sea oil is expensive due to its location under hundreds of feet of water, oil in Saudi Arabia is relatively close to the surface.
