MTN Group, one of Africa’s largest telecommunications companies, expects its headline earnings per share to decline by between 20% and 30% in the first half of 2026, with the pressure largely linked to a writedown on its investment in Iran. The warning highlights the growing financial impact of geopolitical instability and the challenges surrounding MTN’s long-standing presence in the Iranian market.
At the centre of the issue is MTN’s 49% stake in Irancell, Iran’s second-largest mobile operator. The investment has historically contributed significantly to MTN’s earnings. In 2025, Irancell generated revenue of about R16.3 billion and profit after tax of R5.35 billion, with MTN recognising approximately R2.62 billion as its share of the associate’s results.
However, the value and financial contribution of the Iranian investment have become increasingly difficult for MTN to realise. International sanctions, economic instability and heightened geopolitical tensions have complicated the movement of funds out of Iran. Earlier this year, MTN said profits attributable to its Irancell investment remained trapped in the country, limiting the group’s ability to access cash generated by the business.
The latest earnings warning therefore reflects more than a temporary decline in operating performance. It demonstrates how geopolitical risks can affect multinational companies even when their underlying businesses remain profitable. A writedown effectively reduces the accounting value of an investment when its recoverable value is judged to have fallen, creating a direct impact on reported earnings.
The development comes as MTN continues to reshape its broader business strategy around Africa. The group has increasingly identified markets such as South Africa and Nigeria as central to its future growth, while focusing on mobile connectivity, digital services and fintech opportunities.
Nigeria remains particularly important to the group. MTN Nigeria recorded strong growth in the first quarter of 2026, with service revenue rising 41.8% year-on-year and profit after tax more than doubling to ₦355.5 billion, supported by increased data usage and growth in digital financial services.
Despite the expected decline in group earnings, MTN’s wider operating businesses continue to provide a foundation for growth. The challenge is that strong performance in African markets may not completely offset losses or accounting pressures associated with its Iranian investment.
For investors, the situation underscores the importance of looking beyond headline earnings. MTN’s core telecommunications operations remain strategically important, but its exposure to markets affected by sanctions and geopolitical uncertainty can introduce significant volatility.
The Iran situation could ultimately accelerate MTN’s efforts to reduce exposure to difficult markets and concentrate capital on businesses where it has greater control over cash flows. For now, however, the Irancell investment remains a significant reminder that geopolitical risks can quickly translate into financial consequences for global companies.
