RadioShack said Tuesday that it would close up to 1,100 poorly performing stores amid widening losses, or roughly 20% of its locations, as part of an effort to remake itself for a more competitive era of electronic retailing.
The store closings will leave about 4,000 locations in the U.S.
The company has been trying to revamp its stores for the past year.
Yet some analysts say the retailer faces an uphill climb as it struggles to compete against larger big-box stores such as Best Buy.
RadioShack stock (RSH) was down about 15% to $2.31 in afternoon trading
