African Wealth Briefing — Mon., July 6, 2026

Good afternoon from Billionaires.Africa.

Here is a brief on what we published over the weekend.

The weekend's coverage was about second acts — a seized company heading to market, a rescued sugar giant reinventing itself as an energy producer, and a decade-old infrastructure dream finally shipping its first cargo.

The lead: the IPO of a seized empire

Unitel, Angola's largest telecommunications company and once a pillar of Isabel dos Santos's business empire, will launch a roadshow this week for an initial public offering, with the state selling about 15% on the BODIVA exchange in Luanda and a slice reserved for employees. The listing — the centrepiece of Angola's ProPriv privatisation drive — is a public marker of how much dos Santos has lost: she once held 25% through Vidatel before the state seized the stakes in October 2022. Once ranked by Forbes as Africa's richest woman with a fortune above $2 billion, she has never been convicted of a crime, denies all wrongdoing, and says she is the target of a politically driven campaign. The flotation of the company she co-founded is one of the more remarkable stories in African wealth — and this edition's Inside Story examines it in full.

Second acts

Southern Africa — sugar into power. Robert Gumede told Semafor he plans to turn Tongaat Hulett's sugarcane into electricity, ethanol and gases — a diversification designed to save the rescued 134-year-old producer from the cheap-import squeeze we covered last week. If the sugar business can't win on sugar alone, the rescue becomes an energy play.

West Africa — the corridor's first cargo. Samuel Dossou-Aworet's Petrolin Group began operations at Benin's Parakou dry port, shipping its first cotton containers more than a decade after the project was conceived — the first operating piece of his "Backbone" corridor meant to link the Gulf of Guinea to the landlocked Sahel. (Today's Deep-Dive Report profiles the man behind it.)

Friday's file

Nigeria — a contract and a record. Nigeria approved a N1.7 trillion ($1.24 billion) Sokoto–Badagry highway contract for Gilbert Chagoury's Hitech Construction — reported alongside the fact that Chagoury was convicted in 2000 in Geneva of laundering funds for the late Sani Abacha; both the award and the past conviction are matters of record.

Côte d'Ivoire — the BRVM's runaway winner. Jean-Louis Billon's Sucrivoire has surged 190% in 2026, making it West Africa's best-performing stock despite posting an $11 million loss last year — a rally running well ahead of the fundamentals.

East Africa — a guarantee and an award. Heineken posted a $1.9 million bank guarantee to freeze disputed interest on the $11.3 million arbitration award owed to Kenyan tycoon Ngugi Kiuna's Maxam; and Tanzania's chamber of commerce handed Rostam Aziz its highest honor, days after the Uganda media standoff we covered.

Also noted

Femi Otedola's memoir Making It Big was named first runner-up at the BCA African Business Book of the Year in London. And in the diaspora, Haitian-born Herriot Tabuteau — founder of Axsome Therapeutics — is now worth $2.2 billion after the biotech's stock doubled in nine months.

The takeaway

The weekend showed African wealth in its second acts: a fortune seized and re-sold to the public, a rescue reinvented as an energy business, an oil empire converting itself into railways and ports. On this continent, the story rarely ends with the first fortune — the interesting part is what gets built (or unbuilt) next.
