Item 8.01 Other Events.

On November 4, 2014, Healthcare Trust of America, Inc. (NYSE: HTA) (“HTA”) and Healthcare Trust of America Holdings, LP, the operating partnership subsidiary of HTA, entered into an underwriting agreement (the “Underwriting Agreement”) with J.P. Morgan Securities LLC and Wells Fargo Securities, LLC, as representatives of the several underwriters (the “Underwriters”), for an underwritten public offering of 8,000,000 shares of its common stock, $0.01 par value per share (the “Common Stock”), at a price to the public of $12.55 per share (the “Offering”). HTA has granted the Underwriters a 30-day option to purchase up to 1,200,000 additional shares of its Common Stock. HTA issued and delivered 8,000,000 shares of Common Stock from the Offering on November 7, 2014.

In connection with the Offering, certain of the directors and executive officers of HTA have agreed to enter into 60-day “lock-up” agreements in substantially the form attached to the Underwriting Agreement.

HTA received $100.4 million in gross proceeds, before deducting underwriting discounts and commissions and estimated offering expenses. HTA intends to use net proceeds from the Offering to repay a portion of the outstanding indebtedness under the senior unsecured revolving credit and term loan facility and for general corporate purposes, including, without limitation, working capital and investment in real estate.

The Offering was made pursuant to an automatic shelf-registration statement filed with the Securities and Exchange Commission (the “SEC”) on December 24, 2012 (File No. 333-185668), a base prospectus, dated December 21, 2012, included as part of the registration statement, and a prospectus supplement, dated November 4, 2014, filed on November 6, 2014, pursuant to Rule 424(b) under the Securities Act of 1933, as amended.

The foregoing description of the Underwriting Agreement is intended to be a summary and is qualified in its entirety to the terms of the Underwriting Agreement, attached hereto as Exhibit 1.1 to this Current Report on Form 8-K and is incorporated by reference into this Item 8.01.
