Virgin Media added fewer broadband customers in Q4 than its closest rivals BT and BSkyB, and swung to an operating loss.
In the three months ended 31 December, the U.K. cableco netted 103,500 new Internet users, giving it a total of 4.4 million, 3.2 million of which subscribe to services of 30 Mbps or faster.
Over the same period, BT and BSkyB added 150,000 and 110,000 new broadband customers respectively. BT ended 2013 with 7.1 million broadband subscribers to Sky's 5.1 million, leaving Virgin Media firmly in third place.
Virgin Media's TV performance was more encouraging.
After three quarters of net customer losses, the company added 18,600 pay TV customers in the fourth quarter, driven by the popularity of its high-end TiVo service, which is now in 2 million homes.
However, its financial performance was less than stellar.
Q4 revenue fell 1.1% to £1.03 billion driven by declines in business revenue, and its 'other' segment, which includes interconnection and cable installation revenues. Virgin Media also swung to an operating loss of £14.3 million from a profit of £208.5 million a year ago due to higher depreciation and amortisation costs, and higher expenses related to its takeover by Liberty Global.
For the full year, revenue was more or less flat at around £1.7 billion, as triple-play growth was offset by declines at Virgin Media Business and 'other', while operating income was down sharply to £156.4 million from £698.8 million in 2012.
