Billionaire Anil Ambani-led RCom is India's fourth biggest telecom operator.

Highlights Merged entity will be India's 3rd biggest cellular carrier by user base

Transaction to cut Reliance Communications debt by Rs 20,000 crore

Company will have second-largest spectrum holding amongst all operators

Billionaire Anil Ambani's Reliance Communications (RCom) on Wednesday announced a merger of its wireless telecom businesses with Aircel, which will create India's third biggest telecom operator in terms of subscriber base. RCom will own half of the merged the entity, while Aircel's parent, Malaysia's Maxis Communications, will own the other half.The merger comes days after Mr Ambani's older brother and India'a richest man Mukesh Ambani launched Reliance Jio.Analysts expect further consolidation in the telecom sector in the wake of intensifying competition after Jio's aggressive launch.Reliance Communication or RCom and Aircel had been talks for the merger since December last year.The deal will help reduce Reliance Communication's debt by Rs 20,000 crore, or more than 40 per cent of its total debt, while Aircel's debt will fall by about Rs 4,000 crore, the companies said.As of end-March, Reliance Communications had a net debt of Rs 41,362 crore, according to latest company data. Closely-held Aircel had Rs 18,500 crore of debt as of 2013, according to rating agency ICRA.Reliance Communications is India's fourth biggest telecom operator in terms of wireless subscriber base with 9.87 crore customers while Aircel ranks sixth, with 8.8 crore subscribers. The combined entity will surpass Idea Cellular as number three in the sector in terms of subscriber base.Bharti Airtel is the current market leader, followed by Vodafone.The new entity will hold the second largest spectrum portfolio among all operators in India across the 850, 900, 1800 and 2,100 MHz bands. It will have assets of Rs 65,000 crore and will be ranked among India's top corporates."We expect this combination to create substantial long term value for shareholders of both, RCom and MCB (Maxis), given the benefits of the wide-ranging spectrum portfolio and significant revenue and cost synergies," said Anil Ambani, chairman of Reliance Group.In December last year, the two firms had announced that they were entering into a 90-day "exclusivity period" for the merger deal that would exclude RCom's tower and optical fibre assets. The talks were extended twice.India's telecoms market is the world's second biggest behind China in terms of mobile phone subscriptions, but tough competition means low margins for carriers.Reliance Communications had last year agreed to buy Russian conglomerate Sistema's Indian mobile phone business in an all-stock deal.

Reliance Communications also has a pact with Reliance Jio to share some airwaves.(With agency inputs)
