Broker Barclays has raised its target price on Carphone Warehouse after the telecoms retailer did a deal with South Korean electronics giant Samsung to run more than 60 Samsung stand-alone stores across Europe.Barclays upped its price to 290p from 270p, but kept its 'equal weight' rating.On Wednesday, Carphone said it would launch stores selling Samsung's full range of mobiles, tablets and laptops in the next three months in Germany, Ireland, the Netherlands, Portugal, Spain, Sweden and the UK.The broker welcomed the tie-up, saying it would increase earnings for Carphone in 2015 and reassures long-term investors that management is determined to seal profit-making deals.Barclays said in a note: "In our view, the expectation of further collaborations in Europe adds to a positive long-term outlook, but at this point it is difficult to know what the impact on earnings might be longer term."The broker said it expected the 60 Samsung shops to yield a 50% return on capital and was increasing its full-year 2015 legacy pre-tax and pre-interest earnings estimate from £153m to £160m and its earnings per share estimate by 5.5%.It added that it believed Carphone's shares were likely fairly valued now, but added: "We do see increased upside risk to our estimates though from potential further roll-outs in the future."Carphone's shares closed 10.10p up at 297.3p in London.PW
