With the Dangote Petroleum Refinery and Petrochemicals’ Initial Public Offering (IPO) closing today, investors have one last shot to buy into one of Africa’s largest industrial projects at the initial offering.

Priced at N525 per share, the offer is approaching its deadline after the Securities and Exchange Commission (SEC) approved a two-week extension from the original October 13 closing date.

On September 14, Dangote Refinery opened its doors to investors; the IPO comprises 4.1 billion ordinary shares priced at N525 each, giving the offer a total value of N2.1525tn if all the shares are subscribed.

The extension has given investors outside Nigeria more time to participate. Kenya, Uganda and Ethiopia have taken steps to facilitate access, while Zimbabwe is pursuing participation through a proposed Botswana Depository Receipt framework.

Egypt and Rwanda are also exploring possible arrangements, with Botswana emerging as a potential route for investors in Southern Africa. However, the arrangements are at different stages, and not all have received final approval.

For investors yet to apply, the remaining hours offer a final chance to complete their subscriptions. Whether the deadline triggers a late rush remains unclear, as official figures showing the level of applications are not yet available.

The additional two weeks have also given prospective shareholders more time to meet application requirements, including documentation, investor account registration and access to approved subscription platforms.

At N5,250 for the minimum subscription, the offer is within reach of many retail investors. However, the relatively low entry cost does not remove the risks of investing in a business whose future value will depend on its earnings, cash flows, operating performance and expansion plans.

The offer price also does not guarantee a profit. Once the shares begin trading on the exchange, their value could rise or fall depending on demand, company performance and broader market conditions.

A test of Nigeria’s retail-investor appetite

The final day also matters for the Nigerian Exchange (NGX), which has been working to attract more retail investors and expand participation in the stock market.

According to the Nigerian Exchange Group, the Dangote Refinery offer is intended to broaden access to equity ownership beyond established market participants. Efforts to reach investors across other African markets form part of that push.

According to Aliko Dangote, chairman of Dangote Group, one of the core objectives of the offer is to build one of the largest shareholder communities in Africa, with a target of attracting not less than 10 million investors from Nigeria and across the continent.

“If the offer is oversubscribed, retail and small investors will receive priority consideration. We are determined to ensure that ordinary Nigerians are not crowded out by large subscriptions. Our objective is not merely to raise capital but to create millions of shareholders who can participate in the growth and prosperity of the Dangote Refinery. We want as many people as possible to own a stake in this national asset,” Dangote said.

He also disclosed that the IPO had exceeded the amount the company originally intended to raise by more than three or four times.

Reuters reported on October 22 that Temi Popoola, NGX Group chief executive, expected the offer to increase Nigeria’s active investor base by three to five times. The projection points to the potential scale of the exercise, but its actual impact will depend on how many investors complete their subscriptions and continue trading after the offer.

The refinery’s revised indicative timetable sets November 3 for the collation of returns and November 10 for submission of the proposed basis of allotment to the SEC. The regulator’s no-objection is scheduled for November 17, followed by the publication of the allotment announcement and subsequent settlement.

These dates remain indicative and could change if the required processes are not completed as planned.

The closing deadline is therefore more than the end of a share offer. It will mark an early test of whether the refinery can draw a wider pool of Nigerians and African investors into the capital market.

The real measure of success, however, will emerge from the final subscription figures, the number of successful applicants and how the shares perform once trading begins.

For investors still considering the offer, subscriptions close on October 27. The decision to buy should ultimately come down to the company’s prospects and the risks involved, not simply the pressure of a closing deadline.
