FORT WORTH, Texas — RadioShack said Wednesday that its CEO is leaving under an agreement with the board, the latest blow for the struggling electronics retailer.

RadioShack said James Gooch will step down immediately and is leaving its board of directors. Chief financial officer Dorvin Lively will serve as interim CEO while the company looks for a permanent replacement, the company said.

RadioShack has faced declining net income in the past two years. The chain’s troubles are partly due to wider problems in the brick-and-mortar electronics industry and add fuel to the notion that selling consumer electronics in brick-and-mortar stores is becoming less and less viable. But RadioShack has also had company-specific problems. In its latest quarter, the company reported an unexpected $21 million loss, as its shift toward selling smartphones and their accessories was not enough to offset a decline in demand in other consumer electronics.

An analyst said Radio­Shack’s structural problems remain. It is shifting from selling more profitable electronic items like cables to less profitable electronics like smartphones, said KeyBanc capital markets analyst Bradley Thomas. Apple’s iPhone5 launch, which requires new accessories, could be a near-term benefit for the chain, but he advised taking a ‘‘wait and see’’ approach.

RadioShack Corp. said that it is in the process of hiring an executive search firm to help find a new chief executive.

RadioShack’s stock has been hit hard. Since the beginning of the year, its shares are down 74 percent. The stock dropped to a record low of $2.36 in July. Shares rose 4 cents Wednesday to $2.60.
