Healthcare Trust of America, Inc. Announces Acquisition of High Quality Medical Office Building in Novi, Michigan

Scottsdale, Arizona (February 14, 2012) – Healthcare Trust of America, Inc. (“HTA”), is proud to announce the completed acquisition of an approximately 203,000 square foot on-campus medical office building (“St. John Providence MOB”) located in Novi, Michigan, in an all-cash transaction for approximately $51,320,000.

The on-campus St. John Providence MOB is connected directly to the Providence Park Hospital via an enclosed walkway. The Providence Park Hospital is part of Ascension Health Systems (Moody’s Aa1). Developed, owned, and operated since 2007 by a group of independent physician investors, the St. John Providence MOB is currently 99% leased. This off-market transaction was brought directly to HTA through its strong healthcare industry relationships and allows HTA to expand its existing relationship with Ascension Health Systems while providing channels for future growth.

The addition of this asset increases HTA’s national presence into 26 states. The Signature Group will serve as a local point of contact and leasing agent for the asset’s tenants, and HTA’s Indianapolis office will be responsible for overall asset management.

HTA currently has total assets of approximately $2.4 billion based on purchase price, consisting of approximately 11.5 million square feet with overall portfolio occupancy of 91%. HTA remains committed to acquiring high quality MOBs located on or adjacent to nationally recognized healthcare system campuses with the potential for long-term value appreciation.
