Organization and Description of Business

Healthcare Trust of America, Inc., a Maryland corporation, was incorporated on April 20, 2006. We were initially capitalized on April 28, 2006 and consider that to be our date of inception.

We are a fully integrated, self-administered and internally managed real estate investment trust, or REIT, primarily focused on acquiring, owning and operating high-quality medical office buildings that are predominantly located on or aligned with campuses of nationally or regionally recognized healthcare systems. We are one of the largest public REITs focused on medical office buildings in the United States based on gross leasable area, or GLA, and have strong industry relationships, a stable and diversified tenant mix, and an extensive and active acquisition network. Our primary objective is to maximize stockholder value with disciplined growth through strategic investments and to provide an attractive risk-adjusted return for our stockholders by consistently increasing our cash flow. In pursuing this objective, we (i) target mid-sized acquisitions of high-quality medical office buildings in markets with dominant healthcare systems, attractive demographics and that complement our existing portfolio, (ii) actively manage our balance sheet to maintain flexibility with conservative leverage, and (iii) seek internal growth through proactive asset management, leasing and property management oversight. We have qualified to be taxed as a REIT for federal income tax purposes and we intend to continue to be taxed as a REIT. We conduct substantially all of our operations through Healthcare Trust of America Holdings, LP, or our operating partnership.

We invest primarily in high-quality medical office buildings in our target markets, and have acquired high-quality medical office buildings and other facilities that serve the healthcare industry with an aggregate purchase price of $2.7 billion through June 30, 2013. As of June 30, 2013, our portfolio consisted of 250 medical office buildings and 19 other facilities that serve the healthcare industry, as well as a real estate note receivable secured by medical office buildings.

On June 6, 2012, we listed our Class A common stock on the New York Stock Exchange, or the NYSE, under the symbol “HTA,” or the Listing. In accordance with an amendment to our charter approved by our stockholders on December 20, 2010, all of our common stock was converted into Class A, Class B-1, Class B-2 and Class B-3 common stock.
