The impending primary listing of the Dangote Petroleum Refinery on the Nigerian Exchange (NGX) is set to catalyze an unprecedented expansion in domestic equity capitalization.
The upcoming initial public offering (IPO) of Dangote Petroleum Refinery & Petrochemicals FZE is expected to become the largest single listing in the history of the Nigerian Exchange Limited (NGX) pushing the total value of the domestic stock market toward the ₦225 trillion mark.
According to offer documents seen by BusinessDay, the refinery plans to sell 4.1 billion ordinary shares to the public at a fixed price of ₦525 per share. The transaction aims to raise ₦2.15 trillion ($1.6 billion) in gross proceeds, making it one of the largest equity capital-raising efforts in Nigeria’s capital market history.
The public offer represents 4.1 billion shares out of the company’s 120.13 billion total issued share capital, creating a 3.3 percent public float. The transaction will lift the refinery’s total market valuation from ₦63.07 trillion before listing to an estimated ₦65.22 trillion at listing.
By adding roughly ₦2.15 trillion in new value to the exchange within a two-month window, the listing introduces the equivalent of a new top-five company to the local stock exchange. Financial advisers on the transaction include lead issuing house Vetiva Advisory Services Limited alongside a broader syndicate of major Nigerian financial institutions.
The offer is set to open on September 14, 2026, and close on October 13, 2026, giving retail and institutional investors a four-week window to participate. To encourage broad public ownership, the minimum subscription threshold is set at 10 ordinary shares, totaling ₦5,250 supported by a dedicated Retail Investor Incentive Programme.
Primary proceeds from the share sale are designated to support plans to double the refinery’s processing capacity from its current 700,000 barrels per day to 1.4 million barrels per day.

To manage potential demand, the offering includes a provision to absorb up to 30 percent more than the initial share offer if the IPO is oversubscribed, subject to approval from the Securities and Exchange Commission (SEC).
The transaction is not underwritten, meaning the company relies on its own distribution network and pre-existing commitments rather than a bank syndicate guarantee.
Investment analysts at Meristem expect some domestic investors to adjust their existing stock portfolios to free up capital for the IPO. However, the firm notes that the overall shift in market liquidity should remain relatively minor as many fund managers had already set aside reserves ahead of the formal announcement.
In the long term, market experts view the addition of a major industrial and energy firm as a significant structural shift for the NGX, which has traditionally been dominated by banking, telecommunications, and consumer goods companies. The listing is expected to broaden options for institutional and foreign investors while strengthening the global profile of the Nigerian equities market.
