U.K. mobile market consolidation moves up a gear as BT eyes 02, EE by Geoffrey Smith @FortuneMagazine November 24, 2014, 9:25 AM EST E-mail Tweet Facebook Google Plus Linkedin Share icons The deck in the U.K.’s $60 billion telecoms market just got shuffled again, as BT Plc BTGOF confirmed it’s in talks to buy mobile network operator O2 from its Spanish parent Telefonica SA TEFOF . BT, which dominates the fixed-line telecoms business in Britain, has been looking to rebuild its its presence in the mobile market as the industry’s big players concentrate on developing so-called “quad play” offerings that cover both fixed and mobile telephony, along with broadband internet and television. Vodafone Plc VOD , the country’s largest mobile network operator, said last month that it was looking to launch its own TV and broadband services. That’s partly a response to the way that BT has muscled in on the TV market–not least by breaking BritishSkyBroadcasting Plc’s effective monopoly on English Premiership soccer matches. For Telefonica, meanwhile, a sale would strengthen its balance sheet after a major reshuffle of its own portfolio which has seen it place major bets in Brazil and Germany. BT said in a statement to the London Stock Exchange that it has “received expressions of interest from shareholders in two U.K. mobile network operators, one of which is O2.” It added that “all discussions are at a highly preliminary stage and there can be no certainty that any transaction will occur.” The other group believed to be in contact with BT is EE, which is co-owned by France’s Orange SA ORAN and Germany’s Deutsche Telekom AG DTEGF , and which operates the U.K.’s first 4G mobile network. Neither of EE’s parents has signalled any appetite for developing a ‘quad play’ offering in the U.K. and are perceived as potentially willing sellers.
