ATLANTA – September 16, 2013 – BlueLinx Holdings Inc. (NYSE: BXC), a leading distributor of building products in North America, announced today the sale of its office building located in Denver, Colorado.

The Company expects to record a gain of approximately $4.0 million related to this transaction in the third quarter of 2013 as a reduction of operating expense.
