New York - RadioShack is preparing to shut down the almost-century-old retail chain in a bankruptcy deal that would sell about half its store leases to Sprint and close the rest, according to people with knowledge of the discussions.

The locations sold to Sprint would operate under the wireless carrier's name, meaning RadioShack would cease to exist as a stand-alone retailer, said the people, who declined to be identified because the talks aren't public.

The negotiations could still break down without a deal being reached, or the terms could change. Sprint and RadioShack also have discussed co-branding the stores, two of the people said. It's also possible that another bidder could emerge that would buy RadioShack and keep it operating, the people said.

The discussions represent the endgame for a chain that traces its roots to 1921, when it began as a mail-order retailer for amateur ham-radio operators and maritime communications officers. It expanded into a wider range of electronics over the decades, and by the 1980s was seen as a destination for personal computers, gadgets and components that were hard to find elsewhere. In more recent years, though, competition from Wal- Mart and e-commerce sellers hurt customer traffic.

RadioShack received a rescue financing package from Standard General LP in October, and the hedge fund would serve as the lead bidder in a filing and provide debtor-in-possession financing after filing, said the people. That would allow the investment firm to recoup some of the costs of the $535 million loan.

RadioShack has lost more than 90 percent of its value over the past year.

RadioShack CEO Joe Magnacca has been remodeling stores and revamping the retailer's product lineup in a bid to revive sales. Still, the former Walgreen executive hasn't halted a decline at the electronics chain, which has posted 11 straight unprofitable quarters.

Sprint, meanwhile, is expanding its chain. CEO Marcelo Claure told investors at a conference last month that the company would be adding retail locations.

"This is a year in which we intend to grow our distribution dramatically," Claure said. "You are going to see the opening of more and more Sprint stores as this is one area that we work on."
