Updated at 2:55 p.m. ET Friday Sears Holdings Corp., which controls Sears and Kmart, says it has "identified approximately 100 non-profitable stores, 72 of which will begin store closing sales in the near future," in the latest sign of the retailer's struggles to stay afloat. The figure represents about 8 percent of Sears' remaining stores. Sears Holdings announced the closures in its quarterly results released on Thursday, in which it reported total revenues of approximately $2.9 billion — down from $4.2 billion in the same quarter a year ago. Sears has released a list of the affected stores. The company says its overall store sales fell 11.9 percent for the quarter — including a 13.4 percent decline at Sears stores. In the spring of 2017, Sears Holdings had 1,275 stores. At the time, the company acknowledged that "substantial doubt exists related to the Company's ability to continue as a going concern," in a federal filing that cited concerns over its profitability and debt.
