NEW DELHI: Bharti Airtel, India's largest private telecom firm, on Tuesday reported its lowest quarterly net profit in at least 14 years, as competition with free voice calls and dirt-cheap data tariffs from new entrant Reliance Jio ate into its margins.

Airtel posted a consolidated net profit of Rs 82.9 crore (or 21 paisa per share) in January-March quarter of 2017-18 fiscal as compared to Rs 373.4 crore (or 93 paisa a share) in the same period of the previous fiscal.

This was the eighth consecutive drop in quarterly profit and the smallest since April-June 2004.

Billionaire Mukesh Ambani's Reliance Jio, which debuted in September 2016, has signed up a staggering 168 million subscribers by offering affordable data and free calls (and ploughing billions of dollars into the infrastructure and network that transmits them).

Without naming Jio, Gopal Vittal, MD and CEO, India and South Asia, Bharti Airtel said: "The telecom industry continues to witness below cost, artificially suppressed pricing".

Also, industry revenues were further adversely impacted this quarter due to the reduction in international termination rates, he said.

Airtel, he said, continued to consolidate its leadership position during the fourth and last quarter of 2017-18 fiscal.

"Our strategic investments in data capacities, innovative digital content through Airtel TV, customer friendly bundles and upgrade programs led to the highest ever mobile data customer additions of 15 million during the quarter," Vittal said.

Bharti Airtel ended the fiscal year with its highest ever capital expenditure of Rs 24,000 crore. "We intend to continue the rollout momentum next year as well," Vittal added.

Airtel's total revenue fell by 10.5 per cent to Rs 19,634 crore in the fourth quarter of 2017-18, according to an Airtel statement.

For the full fiscal year that ended in March 2018, Airtel's net profit came in at Rs 1,099 crore, over 71 per cent lower than Rs 3,800 crore logged in FY 2016-17.

During the quarter, the India revenues fell 7.5 per cent year-on-year on an adjusted basis to Rs 14,796 crore, even as Africa revenue grew 10.7 per cent over the same period of previous year, fuelled by "strong growth in data and Airtel money transaction value".

Commenting on the domestic market performance, the company said, "Year on year growth primarily (was) impacted by mobile drop of 13.5 per cent".

Other businesses have witnessed healthy year-on-year growth, that is, 10.7 per cent in Digital TV and 11.2 per cent in Airtel Business on an underlying basis, it added.

The company said that its customer base, now at 413.8 million spanning 16 countries, is 12.1 per cent higher year on year (excluding divested units).

Bharti Airtel said that the acquisition of Tigo Rwanda country operations in Africa have been consummated, during the quarter.

Giving details of other operational parameters, Airtel said that the mobile data traffic swelled to 1,616 billion megabytes (MB) in the quarter, up 505 per cent over the year-ago period.

India de-growth weighed in the full year performance too, and the company ended FY18 with total revenue of Rs 83,688 crore, down by 12.3 per cent (on reported basis) over the previous financial year.

The consolidated net debt increased to Rs 95,228 crore from Rs 91,714 crore in the previous quarter, said the company which competes with operators like Vodafone, Idea Cellular and newcomer Reliance Jio in the highly-competitive telecom market in India.

"Lower EBITDA (Earnings Before Interest Tax Depreciation and Amortisation (EBITDA) along with rising spectrum costs and continued investments in India have resulted in deterioration of Return on Capital Employed (ROCE) to 4.7 per cent from 6.5 per cent in the previous year," the statement said.

The Board has declared a final dividend of Rs 2.5 per share (face value of Rs 5 per share) for the financial year ended March 31, 2018. Given the interim dividend of Rs 2.84 per share, the total dividend for the year comes to Rs 5.34 per share which is entirely a pass-through of dividend from the subsidiaries, the company added.

Shares of Bharti Airtel ended at Rs 406.10 apiece on BSE, up 0.61 per cent over the previous closing. The results were announced after the close of market hours.
