South African telecommunications giant, MTN Group released its full year to December 2012 Financial Statement, which shows revenue of R135.1 billion ($14.67 billion) up from R121.8 billion ($13.15 billion) a year earlier.

As expected, a huge chunk (29 percent) of the company’s revenue came from MTN’s Nigerian unit which raked in about 774 billion naira ($4.2 billion). This represents an 11 percent increase over the same period in Rand terms.

In terms of EBITDA margin (Earnings before tax depreciation and amortization), the company made a total R58.6 billion ($6.36 billion) or about 43 percent of revenues. Though, slightly lower than the 44 percent margin obtained a year earlier, the figure is rather impressive considering the global economic Zeitgeist.

Interestingly, Nigeria generated about 38 percent of the total EBITDA margins with R22.5 billion ($2.45 billion). This represents a whopping 58.3 per cent EBITDA margin juxtaposed with revenues earned in Nigeria. The figure is down from the 61.7 percent EBITDA margin posted a year before.

The telecoms giant also more than doubled (45.6 percent)  capital expenditure in Nigeria to R13.7 trillion ($1.49 trillion) in 2012 – by far the highest amongst its units across Africa.

On data revenue, the report showed about 3.8 million registered mobile phones and 301,000 dongles connected to its data services. The company also claimed its revenue from data increased 247.8 percent though the actual figure was not stated.

MTN also recorded good profitability after posting a total profit after tax of R24.06 million ($2.8 million) – a 17.7 percent profit margin, and a 25.8 percent Return on Average Equity.
