Dubai: Royal Bank of Canada, Banco Santander SA and Japan’s Mizuho Financial Group Inc are among banks that have secured bookrunner roles on Saudi Aramco’s initial public offering, people with knowledge of the matter said.

Chinese investment bank BOC International Holdings Ltd and Tokyo-based Sumitomo Mitsui Financial Group Inc are also among 15 joint bookrunners chosen by Aramco, the people said. Middle Eastern firms Saudi Fransi Capital, Al Rajhi Capital, Riyad Bank and EFG Hermes were also picked, the people said.

Aramco is accelerating its listing plans after recovering faster than expected from the biggest terror attacks in its history. The state oil giant plans to formally kick off its much-anticipated IPO next month by announcing the intention to float on October 20, with a target of listing as soon as November, Bloomberg News has reported.

The new banks join fellow bookrunners BNP Paribas SA, Credit Agricole SA, Deutsche Bank AG, Gulf International Bank BSC, Societe Generale SA and UBS Group AG, according to the people. Bank of America Corp, Citigroup Inc, Credit Suisse Group AG, Goldman Sachs Group Inc, HSBC Holdings Plc, JPMorgan Chase & Co., Morgan Stanley, NCB Capital and Samba Financial Group are leading the deal as joint global coordinators, the people said.

Aramco is in the process of selecting co-managers and receiving banks, the people said. Lazard Ltd, Michael Klein and Moelis & Co. are working on the deal as independent financial advisers, according to the people.

Aramco is planning a listing on the Saudi stock exchange, which will include an institutional offering locally and internationally as well as a domestic retail tranche, one of the people said.

The oil producer is considering including additional deal structures — such as a public offering without listing, or POWL, for Japanese investors and a so-called Canadian wrapper that would allow the deal to be marketed in the country, the people said. The company will confirm the potential inclusion of an employee tranche later, one person said.

Aramco didn’t immediately respond to a request for comment. Representatives for the banks had no comment or didn’t immediately respond to requests for comment.
