RadioShack posted first quarter 2013 quarter sales of $849 million and a loss of $43 million, compared with $913 million last year and a loss of $8 million.
RadioShack's transition from offering T-Mobile products and services to offering those of Verizon Wireless took a toll on the company's third quarter profits, though overall sales managed to increase.
A decline in T-Mobile postpaid wireless sales, television converter boxes, digital televisions and digital music players contributed to a first-quarter comps drop of 0.6% at RadioShack.
RadioShack said Monday its chairman and CEO Julian Day is leaving and announced disappointing fourth-quarter guidance. Day, 57, will retire as chairman, CEO and a director as of its annual shareholder meeting on May 16.
