Saudi Aramco has chosen US-based FTI Consulting as global media advisor for what is expected to be the world's largest initial public share offer, according to media reports.
In recent months the Saudi national oil giant has been appointing advisors to help arrange the offer.
Investment banks Moelis & Co, Evercore, JPMorgan Chase & Co and Morgan Stanley will play roles, and more banks will be chosen, the sources said.
FTI 'will support Aramco's communications team ahead of the sale to handle the storm of the IPO", an industry source has told Reuters.
The sources said FTI's main competition in the bidding was international consulting firm Brunswick Group.
