The BT Group is currently deciding whether to buy back O2, 13 years after splitting from them, or potentially buy their rival EE as they plan to re-enter the mobile market.

After BT confirmed discussions yesterday, this new deal could offer a highly potent combination of services. However the company has already secured a deal with EE to use its network to become a mobile virtual network operator, but acquiring its own network would give BT a far more comprehensive offering.

Purchasing a mobile operator would enable BT to accelerate their mobile strategy and will see foreign owners of the mobile networks taking a 20% stake in return for their UK arms.

BT‘s shares have recently jumped by 3.7%.

“This would allow BT to offer a quad-play bundle (TV, telephone, broadband and mobile) using their own network in a market rapidly moving to convergence, BT to generate operating expense savings from ownership of the mobile network and BT‘s Sports investments could be streamed across a larger subscriber base,” said Bank of America analyst David Wright.

If BT takes over O2, the telecom group could be valued at around £10bn.

“In the event that a deal materialises, it would likely force Vodafone, Sky, TalkTalk etc into accelerating their bundle strategies,” said analyst Sunil Patel at Bank of America Merrill Lynch. “This could lead to more deals or partnerships.”

BT said:

“We have received expressions of interest from shareholders in two UK mobile network operators, of which one is O2, about a possible transaction in which BT would acquire their UK mobile business. All discussions are at a highly preliminary stage and there can be no certainty that any transaction will occur.”
