Saudi Aramco, a Saudi Arabian petroleum and natural gas company, is getting closer to its mammoth initial public offering (IPO).

Saudi Aramco plans to raise up to $100 billion from the IPO.

Regulatory processes, including the planned acquisition of a majority stake in Saudi petrochemicals giant SABIC for over $70 billion, still needed to be completed for Saudi Aramco’s shares to be listed.

The IPO will take place in late 2020 or at the start of 2021, two years later than expected.
