A U.S. bankruptcy judge approved Lampert's hedge fund ESL investments Inc's $5.2 billion takeover of the troubled retailer last week, allowing the department store chain to avert liquidation and preserve tens of thousands of jobs.

"It would be very difficult to keep all 425 stores open," Lampert said in the interview, adding that a few stores have already been closed and would probably be sold soon.

Lampert, who stepped down as CEO of the company that filed for bankruptcy on Oct. 15, 2018, while remaining its chairman, also said he would hire a new CEO.

The restructured company, which has 223 Sears outlets and 202 Kmart stores, will keep Sears Auto Centers, Sears Homer Services and the Kenmore and DieHard brands.

Lampert also hinted that Sears would eventually be taken public, saying he doesn't want the company to stay private indefinitely.
