Malvern, PA — November 7, 2013 — Liberty Property Trust (NYSE: LRY) today announced it has entered into an agreement to sell 97 properties totaling 6.6 million square feet of space and 159 acres of land for approximately $705 million. The sale consists of 4.0 million square feet of office properties, 2.3 million square feet of flex properties and 274,000 square feet of industrial properties and includes Liberty’s Jacksonville, Florida portfolio in its entirety, all of the office properties in Maryland, Southern New Jersey and the Fort Washington submarket of Philadelphia and flex properties in Minnesota. The transaction is expected to close in stages with a first closing in late 2013 and a second closing in early 2014 and is subject to the satisfaction of customary closing conditions.
