Dixons Carphone has teamed up with US telecoms firm Sprint to open up stores in the US.
The retailer will open and manage 20 Sprint-branded stores to start with. If that proves successful, the partnership will open up 500 stores across the US.
Dixons Carphone is set to invest up to $32m (£20m) for 50 per cent of the joint venture, making it the first major expansion for the retailer since Carphone Warehouse and Dixons merged.
"This is a very exciting venture for us, and is a significant step in growing our business in the US,” said Andrew Harrison, Dixons Carphone deputy chief executive.
"We bring specialist knowledge and skills to this partnership and will be looking to deliver innovation and outstanding customer service under the Sprint brand."
Earlier this month, Dixons Carphone posted a strong first full year trading statement, revealing that Q4 like-for-like revenue grew nine per cent, while full-year revenue rose six per cent across the board.
In April, the firm revealed that it entered into an agreement to sell its Phone House Deutschland GmbH virtual mobile network operator, signing it over to telecoms provider Drillisch AG.
