Virgin Media O2 has reported falling sales and profits as it lost further fixed line and mobile customers in the first three months of the year. The telecoms group shed another 6,900 fixed line household customers on a net basis – those joining less those leaving – though it said this was a 38,000 improvement on a year earlier as it looks to stabilise its customer base. It lost another 61,500 consumer and business mobile contracts on a net basis in the first quarter, which was narrowed from a 70,300 net loss a year ago. The firm said total underlying revenues, excluding its recent acquisition of Daisy, fell 6.5% to £2.39 billion in the first quarter, while underlying earnings dropped 3.4% to £901.7 million. It expects revenues and earnings to both drop by between 3% and 5% over the year as a whole, but is investing up to £2.2 billion in its networks over 2026, including more than £500 million in the first quarter.…
