The Tariff Hike That Paid for Itself

In February 2025, Nigeria's Communications Commission approved the telecom industry's first tariff increase in over a decade — a 50 percent rise that MTN, Airtel, Globacom and 9mobile all moved to implement amid furious pushback from data-hungry, inflation-squeezed subscribers. A little over a year later, the numbers are in, and for at least one operator the increase did more than cover rising costs. Airtel Africa's results for the financial year ended March 31, 2026 show profit after tax of $813m, up 147.4 percent from $328m the year before. Group revenue reached $6.4bn, up 29.5 percent in reported currency and 24 percent on a constant-currency basis — with Nigeria, the market at the centre of the tariff controversy, posting revenue growth of 47.5 percent in constant currency. Few African companies of any kind posted a swing of that size in a single year.

Data overtakes voice

The deeper story in Airtel's numbers is structural rather than one-off. Data revenue reached $2.53bn, up 40.3 percent, and is now the company's single largest revenue line — ahead, for the first time in the operator's history, of voice. Airtel added 17.4 million subscribers over the year to reach 183.5 million across its African footprint, with smartphone penetration climbing to 49.5 percent and average monthly data consumption rising to 8.9GB per customer, up from 7GB. That combination — more subscribers, more of them on smartphones, each of them using more data — is the underlying engine behind the tariff increase's outsized effect on the bottom line. A price rise on a shrinking or flat user base would have shown up very differently. A price rise layered on top of genuine usage growth compounds.

The other pillar of Airtel's results is Airtel Money, which is starting to look less like a side business and more like a second profit centre. The mobile-money arm grew its customer base 21.3 percent to 54.1 million, processed an annualised transaction value of $215bn by the fourth quarter, and generated $1.36bn in revenue, up 36.3 percent. Combined, data and money growth pushed group EBITDA to $3.16bn, up 37.2 percent, at a margin of 49.3 percent — a level of profitability that would be unusual for a telecom operator in most markets, and reflects how much of Airtel's African business now resembles a fintech company wrapped around a network. The company is reinvesting accordingly: 2026 capital expenditure rose 31.9 percent to $884m, with a further $1.1bn planned for 2027, aimed largely at network densification and data infrastructure.

The regulator's bet, repaid

For Nigeria's regulator, the results amount to a vindication of sorts. The Nigerian Communications Commission spent years resisting operators' calls for a tariff increase, wary of the political cost of raising prices on a population already squeezed by currency depreciation and inflation, before relenting in February 2025. Airtel's numbers give it a case study to point to: revenue growth compounding rather than merely one-off, capital expenditure rising rather than being deferred, and a mobile-money arm scaling fast enough to look like a second business in its own right. That case study matters beyond Airtel, because MTN Nigeria, Globacom and 9mobile all implemented the same increase and are working through comparable dynamics, meaning the tariff decision's true test is not one operator's results but whether the sector as a whole reinvests the windfall into the network quality Nigerians were promised in exchange for paying more.

The results will not settle the argument over whether the 2025 tariff hike was fair to consumers already absorbing double-digit inflation — that debate has echoes in the controversy over Nigeria's Band A electricity tariff, where a similar logic, higher prices in exchange for more reliable service, has provoked its own political backlash. What the Airtel numbers do settle is the question of who benefited financially. Operators that had spent years arguing that below-cost pricing was starving the network of investment now have a year of results to point to. Whether that investment translates into materially better service for the ordinary subscriber whose bill went up by half — rather than simply better margins for shareholders — is the test 2027's numbers will need to answer.
