Exhibit 99.1

December 3, 2012

Dear Fellow Stockholder:

Since our last correspondence, we took additional steps toward our goal of investing the balance of the capital raised during the offering period by the end of 2012.  In keeping with our acquisition philosophy, the properties we purchased include retail tenants that provide goods and services needed by consumers on a daily basis.  Further, a few of the tenants are known in the industry as “value oriented” retailers. These tenants sell higher quality merchandise at discounted prices and have performed very well over the past few years.  Our company’s newest assets are highlighted below:

·                  The Corner, an 80,155 square-foot retail shopping center located in Tucson, Arizona, was purchased for approximately $25.5 million.  The property has an economic occupancy of 100% with 7 tenants including Nordstrom Rack, Five Guys Burgers, Sprint and Select Comfort.

·                  Landings at Ocean Isle Beach, a 53,220 square-foot retail shopping center located in Ocean Isle Beach, North Carolina, was purchased for approximately $10.2 million.  The property has an economic occupancy of 95% with 6 tenants, including Lowe’s Foods, Domino’s Pizza and East Carolina Bank.

·                  University Town Center — Phase II, a 194,917 square-foot retail shopping center located in Norman, Oklahoma, was purchased for approximately $22.3 million.  The property has an economic occupancy of 100% with 14 tenants, including Kohl’s, HomeGoods, Michaels, Shoe Carnival, Rue 21 and Dots.

As of November 27, 2012, Inland Diversified owned and operated 134 properties with a combined purchase price of approximately $1.9 billion, containing 10.5 million square feet of retail, industrial and office properties, and 444 multi-family units.
