Healthcare Trust of America, Inc. Announces Preliminary Results of its Modified Dutch Auction Tender Offer

Scottsdale, Arizona (July 19, 2012) – Healthcare Trust of America, Inc. (NYSE: HTA) (“HTA”) announced today the preliminary results of its modified “Dutch Auction” tender offer for the purchase of up to $150 million in value of shares of its Class A common stock, par value $0.01 per share (the “Class A Shares”), which expired at 11:59 p.m., New York City Time, on July 18, 2012. HTA announced that it was pleased to process the full amount of the tender offer as initially contemplated and meet the properly tendered requests submitted by tendering stockholders. Wells Fargo Securities, LLC acted as the dealer manager for the tender offer.

Based on the preliminary count by Computershare, Inc., the paying agent for the tender offer, and ARC Advisory Services, LLC, the depositary for the tender offer, a total of 22,864,936 Class A Shares were properly tendered and not properly withdrawn at or below the final purchase price of $10.10 per share, including 1,053,398 Class A Shares that were tendered through notice of guaranteed delivery. Based on this preliminary count, the 22,864,936 Class A Shares properly tendered and not properly withdrawn at or below the final purchase price of $10.10 per share represent approximately 39.9% of HTA’s currently issued and outstanding Class A Shares and approximately 10.0% of HTA’s currently issued and outstanding shares of common stock of all classes.

In accordance with the terms and conditions of the tender offer, and based on the preliminary count by the paying agent and the depositary, HTA will accept for purchase 14,851,485 Class A Shares properly tendered and not properly withdrawn prior to the expiration of the tender offer at a purchase price of $10.10 per share, for an aggregate cost of approximately $150 million, excluding fees and expenses relating to the tender offer. Based on this preliminary count, the 14,851,485 Class A Shares to be accepted for purchase in the tender offer represent approximately 25.9% of HTA’s currently issued and outstanding Class A Shares and approximately 6.5% of HTA’s currently issued and outstanding shares of common stock of all classes. Based on these preliminary numbers, HTA anticipates that, following settlement of the tender offer, it will have approximately 42,519,915 Class A Shares outstanding and an aggregate of 214,372,161 shares of common stock of all classes outstanding.

Due to the oversubscription of the tender offer, based on the preliminary count described above, HTA will accept for purchase on a pro rata basis approximately 65% of the Class A Shares properly tendered and not properly withdrawn at or below the purchase price of $10.10 per Class A Share by each tendering stockholder (other than “odd lot” holders, whose Class A Shares will be purchased on a priority basis).
