PRESS RELEASE

Healthcare Trust of America, Inc. Announces Investment-Grade Designation from S&P

Scottsdale, Arizona (July 25, 2011) – Healthcare Trust of America, Inc. (“HTA” or “the Company”), a fully integrated, self-administered, self-managed real estate investment trust, announced that it has been assigned a BBB- corporate credit rating by Standard & Poor’s Rating Services (“S&P”) with a stable outlook.

“This investment-grade designation reflects the quality of our MOB portfolio, our discipline and patience in choosing acquisitions and the conservative approach we take in managing our balance sheet,” HTA’s Chief Financial Officer, Kellie S. Pruitt, stated. “This achievement is another example of the successful execution of our business plan and demonstrates our enterprise value.”

Along with HTA’s low leveraged balance sheet, this credit rating will allow the Company the financial flexibility to access more attractive and competitive forms of debt. Additionally, it will change the interest rate structure under HTA’s $575 million unsecured credit facility, with the potential to reduce borrowing costs.

HTA has 78 geographically diverse portfolios valued at approximately $2.3 billion based on purchase price. The 11.1 million square foot, 242 building portfolio includes 218 medical office buildings, ten hospitals, nine skilled nursing and assisted living facilities and five healthcare-related office buildings located in 25 states. With average occupancy of 91%, over half of HTA’s current annualized base rent comes from credit rated tenants. Ninety-four per cent of HTA’s portfolio is strategically located on-campus or aligned with recognized healthcare systems.

More information regarding HTA’s rating assignment can be found in the Standard and Poor’s research report dated July 21, 2011 available on the website at www.standardandpoors.com. None of the information on this website, including that research report, is incorporated by reference into or is otherwise a part of this press release.

The credit rating assigned to HTA by S&P could change based upon, among other things, HTA’s results of operations and financial condition. This rating is subject to ongoing evaluation by the credit rating agency and we cannot assure you that any rating will not be changed or withdrawn by the rating agency in the future if, in its judgment, circumstances warrant. If this credit rating was to be decreased or withdrawn, it could increase HTA’s overall cost of capital, which could have a material adverse effect on the financial condition and results of operations of HTA. Moreover, this rating relates solely to any debt securities that HTA or its operating partnership may issue and not to its common stock, and it is not a recommendation to buy, sell or hold the common stock or any other securities of HTA.
