An Indian telecom merger will help to seal the truce between the billionaire Ambani brothers. Reliance Communications, backed by younger sibling Anil, is buying the Indian unit of Russia's Sistema, giving the country's fourth largest mobile operator vital extra spectrum.
The long-overdue consolidation makes indebted RCom an even more attractive partner for a soon-to-launch upstart led by older brother Mukesh.
A bitter power struggle between the pair following the death of their father led to a split in the Reliance empire in 2006.
Mukesh took the flagship energy business and Anil ended up with telecom, financial services and power.
The brothers only started doing business together again in 2013, when cash-starved RCom agreed to lease its fibre optic network and share masts with the venture Mukesh is using to re-enter the telecom industry.
Reliance Jio, which will offer fast data services, is due to launch in December.
Absorbing Sistema gives RCom extra spectrum.
This will allow it to push ahead with a nationwide agreement to share airwaves with RJio without having to give up its existing revenue-generating voice business. In return, Sistema gets a 10 per cent equity stake in RCom, worth $289 million before the deal was announced.
Anil refers to the pending telecom tie-up between the brothers as a "virtual consolidation" in an industry desperately in need of fewer players.
Though detailed financial information about the alliance has yet to be revealed, sharing spectrum should boost revenue at RCom, which is struggling with net debt that stood at $6.1 billion at the end of June. Meanwhile, RJio will be able to fall back on RCom's network where its own is weak.
Strict rules that limit the amount of spectrum a single operator can hold probably preclude a full takeover of RCom by RJio. But together the pair will be a formidable rival to larger players like Bharti Airtel and Vodafone which will offer high-speed services using less efficient spectrum.
The 8 per cent rise in RCom shares on the back of the Sistema deal suggests investors are optimistic about a deeper and more lucrative rapprochement between the brothers.
