Consolidated net profit fell to 14.62 billion rupees ($218 million) in the quarter ended June 30, from 21.13 billion rupees last year, the company said.
Analysts on average had expected a net profit of 11.59 billion rupees, according to Thomson Reuters data.
Bharti Airtel, headed by Indian billionaire Sunil Mittal, said total revenue rose 7.9 percent from a year earlier to a record 255.47 billion rupees, helped by new customers signing up for the company’s 3G and 4G data services.
During the quarter, the Nigerian naira depreciated by 42 percent, forcing the company to register an exceptional loss of 7.48 billion rupees as a result. Bharti derives about 7 percent of its consolidated EBITDA (earnings before interest, tax, depreciation and amortisation) from Nigeria, analysts estimate.
Restructuring in some other countries also hurt profits, the company said.
Mobile data revenue during the June quarter rose 35 percent to 35.25 billion rupees from a year ago, Bharti Airtel said. Average revenue per user (ARPU) of data rose 10-fold from a year earlier to 202 rupees during the quarter.
