'Integral Component'
The listing forms the linchpin of Prince Mohammed's ambitious plans to overhaul the oil-reliant economy, with tens of billions of dollars needed to fund megaprojects and new industries.
First suggested by the kingdom's de facto ruler in 2016, the IPO was delayed several times reportedly due to his dissatisfaction with the valuation of the firm, which fell short of the hoped for $2 trillion.
Last week, Energy Intelligence cited sources as saying they expect the Saudis to settle on a valuation of $1.6 trillion to $1.7 trillion for the firm.
If confirmed, that would imply the kingdom is ready to accept a compromise of less than the $2 trillion that Prince Mohammed has long insisted the state oil giant is worth.
It remains to be seen whether Saudi authorities are able to find "a compromise between the crown prince's stated preference and market realities in their valuation of Aramco," said Kristian Ulrichsen, a fellow at Rice University's Baker Institute in the United States.
"As the process has been delayed repeatedly and built up as such an integral component of the crown prince's plan to transform Saudi Arabia, international investors will pay very close attention to how Aramco performs on the domestic exchange," Mr Ulrichsen told news agency AFP.
Aramco, which pumps around 10 per cent of the world's oil, is the most profitable company globally and is seen as the kingdom's crown jewel and the backbone of its economic and social stability.
Saudi Arabia has boosted efforts to woo investors to the long-awaited stock market debut by announcing an annual dividend of $75 billion, according to the company's website.
Riyadh is also reportedly seeking to get wealthy Saudi families to buy a stake in the company while some Saudi commentators have sought to promote investment in the stock as a patriotic duty.
However, Aramco executives have encountered scepticism among institutional investors in London and New York on questions about the firm's transparency, governance practices and targeted valuation, sources have told AFP.
"An important function of the domestic IPO is to project confidence in the company towards the international market, but doing it domestically encounters no meaningful obstacle, comparable to doing an international listing," said Cinzia Bianco, Gulf research fellow at the European Council on Foreign Relations.
"It allows Prince Mohammed to show he keeps his promises and gets things done, another step to reassure international investors that the IPO will happen after all," Bianco said.
Saudi Arabia's market regulator approved on Sunday Saudi Aramco's application to list on the domestic stock market as the kingdom seeks to diversify and create the world's most valuable listed company.
The statement did not give a timeframe or say how much Aramco would sell, but sources have told news agency Reuters the oil company could sell 1-2 per cent of its shares on the local bourse, raising as much $20 billion-$40 billion.
Confirmation of the share sale in Saudi Arabian Oil Co, or Aramco, as the oil giant is usually known, comes about seven weeks after crippling attacks on its oil facilities, underlining Saudi Arabia's determination to push on with the listing regardless.
The IPO of the world's most profitable company is designed to turbo charge Crown Prince Mohammed bin Salman's economic reform agenda by raising billions to diversify the kingdom, whose dependency on oil was highlighted by the production impact of the September 14 attacks.
The Capital Market Authority said its board "has issued its resolution approving the Saudi Arabian Oil Company (Saudi Aramco) ... application for the registration and offering of part of its shares."
CMA said the approval would remain valid for six months.
The listing announcement had been expected on October 20 but was delayed after advisers said they needed more time to lock in cornerstone investors, three sources told Reuters.
To help get the deal done, Saudi Arabia is relying on easy credit for retail investors and hefty contributions from rich locals.
Prince Mohammed gave the green light on Friday for the IPO to go ahead, Reuters reported, citing sources.
Although Crown Prince Mohammed put a $2-trillion valuation on the company in early 2016, bankers and company insiders say Aramco's value is closer to $1.5 trillion.
A growing movement to fight climate change and embrace new "green" technologies have put some fund managers, particularly in Europe and the United States, off the oil and gas sector.
At a valuation of $1.5 trillion, Aramco would still be worth at least 50 per cent more than the world's most valuable companies, Microsoft and Apple, which each have a market capitalisation of about $1 trillion.
But a 1 per cent sale would 'only' raise around $15 billion for Saudi coffers, less than the $25 billion generated by Chinese e-commerce giant Alibaba in its record-breaking IPO in 2014.
It would rank Aramco as the 11th biggest IPO of all time, Refinitiv data show.
A sale of 2 per cent of Aramco shares at a $1.5-trillion valuation would make it the biggest IPO of all time, beating Alibaba's.
The prospect of the world's largest oil company selling a piece of itself has had Wall Street on tenterhooks since Crown Prince Mohammed flagged it three years ago.
Initial hopes for a blockbuster international listing of about 5 per cent were dashed when the share sale was halted last year amid debate over where to list Aramco overseas.
Aramco said the IPO timetable was delayed because it began a process to acquire a 70 per cent stake in petrochemicals maker Saudi Basic Industries Corp.
IPO preparations were revived over the summer after Aramco attracted huge interest in its first international bond sale, seen as a pre-IPO relationship-building exercise with investors.
The bond sale forced the secretive company to reveal its finances for the first time, including net income of $111 billion, over a third bigger than the combined net income of the five super majors Exxon Mobil, Royal Dutch/Shell, BP, Chevron and Total.
Oil majors have been raising payouts to shareholders to counter rising pressure from climate activism.
Aramco has said it will pay a base dividend of $75 billion, which at a valuation of $1.5 trillion would mean a dividend yield of 5 per cent, below those offered by competitors such as Exxon Mobil Corp and Royal Dutch Shell.
Shell's dividend yield is over 6 per cent and Exxon's over 5 per cent, according to Refinitiv data.
Adverse Impact
The September attacks on Aramco's largest oil plant, which shut off about 5 per cent of global supply, raised questions about the vulnerability of Aramco's oil fields, plants and exports amid deepening regional tensions.
In its April bond prospectus, Aramco noted that any disruption to its processing facilities could harm its business.
The potential threat to the company's valuation presents a challenge for Yasser al-Rumayyan, head of the kingdom's sovereign wealth fund, who became Aramco chairman in September.
Al-Rumayyan replaced former energy minister Khalid al-Falih in a move to separate Aramco from the ministry ahead of an IPO.
Aramco hired nine banks as joint global coordinators to lead the IPO, including JPMorgan, Morgan Stanley and Saudi Arabia's National Commercial Bank. It added a number of banks as book-runners.
