- Total third-quarter revenues rise- 4G mobile launch to boost results- FY earnings guidance reiteratedCarphone Warehouse Group's third-quarter like-for-like revenue rose a modest 3.1 per cent as consumers waited for the roll out of fourth generation (4G) mobile products. UK like-for-like revenue increased 5% in the three months ended December 28th and gained market share in both the pre-pay and post-pay categories.It came despite a decline in pre-pay market volumes and broadly flat post-pay connections."As anticipated, post-pay volumes remain subdued while the market transitions to 4G," said Chief Executive Andrew Harrison."Against this, our strong brand awareness and our excellent retail execution meant that Carphone Warehouse again increased its UK market share. Our new Pin Point selling tool has proved particularly effective in driving the penetration of 4G tariffs and increasing revenue per connection."Virgin Mobile France, the group's joint venture with Virgin, saw its revenue fall year-on-year by 15.6%, reflecting fewer customers.Carphone expects to acquire new post-pay customers while keeping existing customers on the launch of 4G. The company reiterated group headline earnings per share guidance for the full year of between 17p and 20p, with a pro-forma headline earnings before interest and tax range of £140m to £160m."Whilst challenging market dynamics across Europe remain, we are very encouraged by the impact of 4G to date and expect its momentum to build as 4G network capacity is expanded across all of our European markets," Carphone said.Shares held at 279.80p at 10:16 on Tuesday.
