South Africa-listed fintech company Optasia, said it expects revenue for the first half of 2026 to increase by between 50 percent and 60 percent compared with the same period last year, driven by strong performance in Ghana, Pakistan, Indonesia and the Republic of Congo

The positive trading update excited investors, sending Optasia’s shares up more than six percent on the Johannesburg Stock Exchange (JSE), marking the company’s biggest rally since its stock market debut in November.

The performance comes despite a two-month disruption to its Airtime Credit Services (ACS) business in Nigeria following changes to regulations governing non-traditional lending. Although Nigeria remains one of the company’s important markets, growth in other countries helped cushion the impact of the setback.
