Seplat Petroleum Considers Dual Stock ListingSeplat Petroleum Development Co., a Nigerian oil company that bought assets in the Niger River Delta from Royal Dutch Shell Plc (RDSA), is considering listing shares on two stock exchanges, according to Managing Director Augustine Avuru. “A dual listing remains an option for Seplat for equity-raising,” he said in a telephone interview on Nov. 8, declining to comment further. She said the Nigerian regulator approved the listing from the company with consent from the other exchange expected this month. The Nigerian Stock Exchange (NGSEINDX) will target 500 companies for initial public offerings over the next five years as Africa’s second-largest bourse seeks to reach a $1 trillion market capitalization by 2016, according to Oteh. Oando Plc (OANDO), a Nigerian oil production company listed in Lagos and Johannesburg, has dropped 11 percent this year on both exchanges.
