AOL and TalkTalk broadband products have fallen short of sales targets set by owner Carphone Warehouse, profit figures show.
AOL and Talk Talk marginally missed out on sales targets for broadband, according to their financial results for the end of last year.
In its fourth quarter report, Carphone Warehouse - which owns the companies - noted 109,000 new TalkTalk and AOL broadband installations, taking its total user base to 2.7 million throughout the UK.
Of those, 1.8 million were using unbundled services, while only a small number continued to be supplied by BT Wholesale exchanges.
Analysts expected the group to attract 128,000 new customers over the period, with the shortfall causing its share price to tumble today, Reuters reports.
"Our performance over the last three months has been good in a slower consumer environment," said chief executive Charles Dunstone.
The company is expected to attract around 400,000 new customers up to March 2009, with the group stating that it was confident of considerable future progress in tough economic conditions.
Carphone Warehouse will issue its next profit report on June 3rd, which will record results for the first quarter of 2008.
