MTN Group wrote down its Iranian investment by R3.9-billion in the six months to end-June, and still carries R10.5-billion of Irancell net assets on its books. Both numbers now sit directly in the path of what US treasury secretary Scott Bessent has promised will be “the toughest sanctions in history” on Iran.

US President Donald Trump posted on Truth Social last week that “any country that allows its financial institutions, businesses, airports or government entities to provide any type of lifeline to Iran will itself face tremendous economic consequences”. He listed the conduits he had in mind: “Oil smuggling, swap lines, cash transfers, exchange houses, ship registries, front companies – it all needs to stop now.”

Bessent followed the next day on CNBC: “It is a one-two punch. We have the blockade, and we are going to have the toughest sanctions in history.” He returned to it in a Financial Times op-ed on Sunday and was due to set out the detail on Monday, the same day MTN released its interim results.

MTN owns 49% of Irancell, licensed in 2005 as Iran’s second mobile network. The other 51% sits with Iranian state-linked shareholders. It is a non-controlling, equity-accounted stake that MTN has been trying to leave for years, and cannot.

“With sanctions in place as they stand right now, we can’t put any money in, and we can’t take any money out,” group CEO Ralph Mupita told journalists on Monday.

That has been the position since May 2018, when the first Trump administration abandoned the Iran nuclear deal. The snapback that followed cut designated Iranian banks off from the Swift messaging network by that November. “Iran has been a trapped investment since May 2018 … we haven’t put any money in, haven’t taken any money out,” Mupita said.

Stranded cash

The stranded cash is smaller than it was, but only because the currency collapsed. MTN disclosed about R886-million of receivables owed by Irancell at period end, with repatriation “constrained by the prevailing sanctions regime”. Mupita put it more plainly: “Post the devaluation, the total amount is just over R880-million equivalent of trapped dividends.”

That is not the only Irancell receivable on the books. A separate note puts the outstanding Irancell loan and receivable at R2.01-billion, classified as non-current because settlement is “neither planned nor likely to occur in the foreseeable future” and carried within investment in associates and joint ventures. It stood at R2.31-billion in December and R2.55-billion a year ago. The results do not spell out how the two figures relate.

It is not the first such trap. Under an earlier sanctions round MTN had roughly US$1-billion stuck in Iran, which it only recovered in 2017, shortly before the door slammed shut again.

Irancell has been legally fraught from the start. Turkcell, originally selected for the licence, has for more than a decade alleged that MTN won the concession through bribery and political influence in South Africa and Iran. Its $4.2-billion claim has reached the constitutional court and names former group CEO Phuthuma Nhleko and former director Irene Charnley, both of whom deny the allegations. Separately, MTN disclosed last August that a US justice department grand jury is examining its former Afghan and current Iranian operations; it says it is cooperating.

Meanwhile the rest of the Middle East portfolio has been dismantled. MTN left Syria and Yemen in 2021 and Afghanistan last year, and this year agreed a settlement with Syria’s telecoms regulator worth $43.9-million, booked as a R716-million gain.

“The only thing that’s left is the investment in Iran,” Mupita said. “In an environment where sanctions were removed, we would continue to execute and exit the market best we can. But obviously, that’s not the case right now.”

MTN has also lost what little visibility it had. As TechCentral reported in March, its position had deteriorated to “can’t stay, can’t leave” after Irancell’s state-backed majority appointed a new chief executive without consulting it, leaving MTN with no executive on the ground and no seat on the board.

The war did the damage

The write-down was flagged two weeks before results. A trading statement on 11 August attributed the impairment to “geopolitical and economic conditions as well as the war in Iran”, after a US and Israeli air campaign struck targets across the country.

The latest impairment came to 213c/share, up from 104c a year earlier. It is why basic earnings per share, which carries the hit, came in at 404c while headline EPS, which strips impairments out, came in higher at 615c. The 211c gap between the two is almost entirely the write-down.

Adjusted headline EPS, MTN’s preferred operating measure, rose 21.3% to 793c, within its 775c-to-808c guidance. Strip Irancell out and the figure is lower in rand, at 767c, yet the growth rate is higher, at 23.7%, because Irancell adds to adjusted earnings – about 26c/share this half – and that contribution was bigger a year earlier.

One quirk will trip up anyone checking those percentages against the 11 August trading statement. MTN restated its first-half 2025 comparatives 8c higher, to 547c basic EPS and 653c headline EPS, for MTN Ghana accounting changes. Off the restated bases the falls are 26.1% and 5.8%; off the originals, nearer 25% and 5%.

On the call, Mupita put the write-down down to accounting rather than politics: Iran’s persistent hyperinflation and the rial’s sharp depreciation over the past six months. That leaves R10.5-billion on the balance sheet. “At the full year we’ll reassess what that investment level will be and apply whatever are the necessary accounting adjustments, up or down.”

The exposure

MTN’s practical defence against secondary sanctions is the very thing that makes Irancell useless to it: there are no flows. No capital goes in, no dividends come out, and MTN neither runs the business nor sits on its board.

But the character of the asset has changed. A 49% stake in an operator MTN no longer helps run, in a country under a tightening blockade, is very different to a company already answering a US grand jury’s questions about the same country. Washington’s message last week was that any conduit, however passive, is fair game.

A harsher regime makes the relief MTN’s exit depends on less likely, pushing recovery of the trapped receivables further out and raising the odds of another impairment at year-end. It also keeps an Iranian line on the books of a group that needs continuous dollar funding, with a Eurobond maturity ahead, just as Washington tells banks everywhere to sever anything resembling a lifeline to Tehran.

MTN’s balance sheet is otherwise in good shape, with group net debt to Ebitda steady at 0.3x, R39.1-billion in liquidity headroom and a R6-billion share buyback about to start. Iran is a rounding error against that. It is also the one exposure on which the company has no lever to pull. – © 2026 NewsCentral Media
