MTN Group (JSE: MTN), Africa's largest mobile operator by subscribers, said it would welcome any easing of tensions between the United States and Iran amid reports that diplomatic discussions could eventually pave the way for sanctions relief and potentially unlock the South African company's long-troubled investment in the country.

Sanctions relief is among the issues under discussion between Washington and Tehran. Such a move could eventually allow MTN to exit Irancell, the Iranian mobile operator in which it owns a 49% stake, MyBroadband writes.

South Africa-based MTN has been retreating from the Middle East since 2020, having already exited operations in Syria, Afghanistan and Yemen. Iran remains the last major asset in the region.

Years of US sanctions have effectively trapped MTN's investment, preventing the company from repatriating funds or disposing of its stake. Group chief executive Ralph Mupita previously described the investment as a "frozen asset", with around ZAR2.3bn ($128mn) inaccessible because of US restrictions.

Washington’s sanctions on Tehran have been tightened repeatedly over the past two decades, with additional measures imposed in 2019 following attacks on Saudi oil facilities that the US blamed on Iran. Those restrictions further isolated Iran from the international financial system and limited the options available to foreign investors.

Irancell is Iran's second-largest mobile operator and serves more than 50mn subscribers through a joint venture between MTN and local partners, and competes primarily with state-backed Mobile Communication Company of Iran (MCI). Prior to tighter sanctions and the sharp depreciation of the Iranian rial, the business was among MTN's most profitable foreign investments, according to MyBroadband.

Established in 2005, Irancell has grown into one of the Middle East's largest mobile operators and was long viewed as a strategic gateway to a market of nearly 90mn people. Before sanctions intensified, the investment contributed significantly to MTN's international earnings and represented one of the group's largest exposures outside Africa.

Economic deterioration has eroded value

Years of sanctions and economic instability have steadily eroded the value of MTN's Iranian investment. Iran's economy has weakened sharply, particularly since 2025, with the rial losing substantial value amid tensions involving Iran, Israel and the United States.

MTN's latest results show that outstanding receivables from Iran fell to ZAR2.8bn, while its share of earnings from Irancell declined 32% year on year to ZAR3.2bn ($178mn). Even if sanctions are eventually eased, years of inflation, currency depreciation and economic instability may have significantly reduced the underlying value of the business.

Sanctions have also restricted access to international banking channels and complicated the repatriation of profits, leaving MTN largely unable to realise value from one of its largest foreign investments. Analysts caution that sanctions relief would not necessarily translate into a quick monetisation of the stake, given exchange-rate losses and the complexity of restoring international financial channels.

Investors have long applied a discount to MTN's valuation because of uncertainty surrounding its Iranian exposure. Any credible pathway towards sanctions relief and a potential exit could remove a longstanding overhang on the stock, although analysts caution that years of currency depreciation and economic weakness may limit the ultimate proceeds from any disposal.

Diplomatic thaw could unlock frozen asset

MTN has declined to speculate on the implications of any future agreement ending the war but said it would welcome developments that contribute to peace and stability in the region.

The company's retreat from the Middle East forms part of a broader strategy to simplify its portfolio and focus on African markets, fintech services and digital infrastructure. MTN has increasingly prioritised fintech and digital infrastructure investments, with its mobile money operations emerging as one of the group's fastest-growing businesses.

MTN's retreat from the Middle East mirrors a broader trend among African telecom operators towards simplifying portfolios and focusing on higher-growth markets, fintech platforms and digital infrastructure. The group's mobile money business now generates a growing share of earnings and has become central to its long-term strategy.

Any sanctions relief would likely be gradual and subject to compliance with future agreements. Nevertheless, any durable easing of sanctions could remove one of the biggest uncertainties hanging over MTN's international portfolio, potentially allowing the group to complete its withdrawal from the Middle East and concentrate entirely on expanding its African telecom and fintech businesses.
