Johann Rupert & family

Who Johann Rupert is

Johann Rupert chairs two companies that between them touch a remarkable share of South African corporate life: Compagnie Financière Richemont, the Swiss-listed luxury group that owns Cartier, Van Cleef & Arpels and Montblanc, and Remgro, the Stellenbosch investment holding company that grew out of the business his father built. He is, on every published estimate, either the richest or the second-richest person in South Africa — and the fact that serious publications disagree about which is a useful way into how a fortune like his is actually measured.

Forbes put him at US$16.3 billion in 2025 and called him the country's second-richest person. The Bloomberg Billionaires Index put the same fortune at US$19.3 billion. A three-billion-dollar gap between two careful, well-resourced indices is not sloppiness. It is what happens when most of a fortune sits inside a structure where control and ownership are deliberately different things.

Stellenbosch, New York, and back

Rupert was born in Stellenbosch on 1 June 1950. He went to Paul Roos Gymnasium and then to Stellenbosch University to read economics and company law, but left before finishing the degree — a detail he has never been especially precious about, and one the university revisited in 2004 when it awarded him an honorary doctorate. Nelson Mandela Metropolitan University followed in 2008 and the University of St Andrews in 2010.

Instead of a degree he took a New York apprenticeship: two years at Chase Manhattan and three at Lazard Frères. Merchant banking in New York in the 1970s was a good place to learn how deals are structured, and structuring is the thread running through everything he did afterwards. His career makes far more sense read as the work of a dealmaker than of an operator of luxury businesses.

The bank he founded

Rupert returned to South Africa in 1979 and founded Rand Merchant Bank, becoming its chief executive.

What happened next is the origin of a great deal of the wealth further down this index, and it is worth being careful with the dates, because the sources disagree. Rupert’s own biography records a 1984 merger of RMB with Rand Consolidated Investments to form RMB Holdings. Rand Merchant Bank’s corporate history records instead that Rand Consolidated Investments acquired control of RMB in 1985, and that Rand Merchant Holdings was created as a holding company for the expanding business in 1987. We give both rather than quietly pick one, because we have not found a document that settles it.

What is not in dispute is the lineage. In 1998 FirstRand was created through the merger of RMB Holdings with Anglo American’s financial services interests, and three separate entries on this index — Laurie Dippenaar, GT Ferreira and Paul Harris — built their fortunes in the group that came out of it. The bank Rupert started in 1979 is the ancestor of what is now the largest listed financial services institution in Africa, with over R1.7 trillion in assets under management.

Taking over at Rembrandt

Also in 1984, Rupert joined his father Anton's Rembrandt Group. He became vice chairman in 1989 and chairman in 1991.

Anton Rupert had built Rembrandt out of the Voorbrand Tobacco Company, renamed Rembrandt Trust in 1948, into a conglomerate spanning tobacco, mining, financial services and consumer goods. What the son did with it was less about operating those businesses than about reorganising who owned them, and in which country. Over the following two decades the group was taken apart and rebuilt three times.

1988: the split that created Richemont

On 20 September 1988 Rembrandt's international assets were separated into a new Swiss company, Compagnie Financière Richemont, headquartered at Bellevue outside Geneva. South African and offshore interests were placed under different roofs, in different jurisdictions, with different shareholder registers.

Richemont went on to assemble one of the two or three most valuable collections of luxury brands in the world. Its maisons include Cartier, Van Cleef & Arpels, Montblanc, IWC Schaffhausen, Jaeger-LeCoultre, Piaget, Panerai, Vacheron Constantin, Chloé, Alaïa and Dunhill. In the 2025 financial year the group reported revenue of €21.4 billion and net income of €2.75 billion.

Not everything worked. Richemont's push into online luxury through YOOX Net-a-Porter was an expensive lesson. In August 2022 it announced a planned sale of a 47.5% stake to Farfetch; in January 2024 Farfetch was itself acquired by the Korean e-commerce group Coupang, which ended that transaction; in October 2024 Richemont agreed instead to sell the platform to Mytheresa.

Ten per cent of the money, fifty-one per cent of the votes

This is the single most important fact about Johann Rupert's fortune, and the reason the published estimates diverge.

Compagnie Financière Rupert, the family's private Swiss vehicle, holds 6,263,000 Richemont Class A shares and 522,000,000 Class B registered shares — a position representing 10% of the equity of the company and controlling 51% of the company's voting rights.

Read that twice. Ten per cent of the economics; an outright majority of the votes. The A shares are the ones that trade; the B shares carry voting power out of all proportion to the capital they represent. The arrangement means the family cannot be outvoted on anything, no matter who else buys the stock, and it means Rupert has never needed to own a majority of Richemont in order to control it.

For a wealth index this creates a genuine measurement problem rather than a trivial one. A bottom-up index values an economic stake: shares held, multiplied by the current price. It does not value control. Yet control is precisely what the B-share structure exists to deliver, and a controlling block would not change hands at the screen price. Whether you add a control premium — and how large it should be — is a judgement call, and it is a large part of why two indices as serious as Forbes and Bloomberg land three billion dollars apart on the same man.

Remgro

The South African half of the family's interests sits in Remgro, listed on the JSE under the ticker REM. Remgro emerged from a 2000 restructure that split the old Rembrandt Group into Remgro and VenFin; the two were merged back together in 2009 after the British American Tobacco stake was spun off.

Rupert chairs it. Jannie Durand, also on this index, is chief executive.

Remgro is unusually useful for an index, because it publishes its own sum-of-the-parts. Its stated intrinsic values as at June 2025 included Mediclinic at 50% (R41.50 billion), OUTsurance Group at 30.5% (R36.77 billion), RCL Foods at 79.6% (R7.86 billion), Heineken Beverages at 18.8% (R6.74 billion) and FirstRand at 1.6% (R5.73 billion). That is a company telling the market what it believes its assets are worth, line by line — considerably better evidence than an outsider's estimate, and the kind of disclosure this index prefers to build on.

Reinet: the third vehicle

There is a third structure most summaries miss. Reinet Investments S.C.A. was demerged from Richemont on 20 October 2008, is domiciled in Luxembourg and trades on the Luxembourg Stock Exchange as REIN. Rupert chairs it.

Its purpose was tidiness: it let the family separate out everything that was not luxury goods, so that Richemont could concentrate on its maisons. Reinet began with €350 million in cash, roughly €50 million of miscellaneous investments and a 4% holding in British American Tobacco — 84.3 million shares, worth about £1.46 billion (€1.88 billion) on its first day of trading. In early 2009 it bought Lehman Brothers' private-equity business, which became Trilantic Capital Partners.

Three vehicles, three jurisdictions, three listings: Richemont in Switzerland, Remgro in Johannesburg, Reinet in Luxembourg — with the private Compagnie Financière Rupert sitting above them. The shape of the fortune is then clear enough. It is not a company. It is an architecture, and it was built deliberately.

How Rateweb values him, and where we differ

Our index carries Johann Rupert & family as South Africa's largest fortune. Forbes ranks him second. We publish that disagreement rather than paper over it, because what it turns on is informative: the treatment of a controlling stake in a foreign-listed company, the rand-dollar rate applied, and how much of the private structure any outsider can actually see.

What can be stated precisely is the listed portion. Richemont's share register and Remgro's own intrinsic-value tables are public documents that anyone can check. What cannot be stated precisely is what the private Rupert vehicles hold beyond those, and we do not pretend otherwise — see our methodology for the general approach. The confidence rating on this profile reflects the specific uncertainty attached to a control block rather than any doubt about the underlying companies.

Outside the balance sheet

Rupert founded the Laureus Sport for Good Foundation in 1990 and co-founded the Sports Science Institute of South Africa with Morné du Plessis and Tim Noakes. He developed the Leopard Creek golf course on the edge of the Kruger National Park and has chaired both the South African PGA Tour and the Golf Development Board. He was inducted into the South African Sports Hall of Fame in 2007 and the Golf Hall of Fame in 2009. In 2008 he bought a 50% stake in the English rugby club Saracens, selling it in 2018.

He was Chancellor of Stellenbosch University from 2009 to 2019 — the institution he left without a degree — and has been non-executive chairman of Gold Fields South Africa since 1997.

He is also, unusually for someone in his position, a frequent and blunt public commentator on the South African economy, which has made him a far more visible figure at home than most people of comparable wealth choose to be.

What we do not know

A great deal, and it is worth being explicit about it. Compagnie Financière Rupert is private and publishes no accounts. Family trusts, property, art, wine and conservation interests are not disclosed in any form an index can value. Where a figure cannot be built from a public disclosure we leave it out rather than estimate it, which means our number is more likely to understate this fortune than to overstate it.
