Exhibit 99.1

STAG INDUSTRIAL, INC. REPORTS SECOND QUARTER 2011 RESULTS AND PROVIDES HIGHLIGHTS

Boston, MA — August 15, 2011 - STAG Industrial, Inc. (the “Company” or “STAG”) (NYSE:STAG), is a self-administered and self-managed real estate company focused on the acquisition, ownership and management of single-tenant industrial properties throughout the United States. On April 20, 2011, the Company closed on its initial public offering (IPO) and the related formation transactions to aggregate its predecessor and other funds owned by affiliates of the Company. As the Company was not a public company for a portion of the second quarter, the Company’s quarterly report on Form 10-Q for the second quarter 2011 reflects the results of its predecessor from April 1 through April 19 and the results of the Company for the remainder of the second quarter and is therefore not representative of the Company’s consolidated future results.

As of the date of this release, the Company owns 96 industrial properties totaling 15.1 million square feet.  The Company has a full service platform that incorporates acquisitions, asset management, credit, accounting and legal functions.

“We are excited to be reporting on our recently completed first quarter as a public company.  STAG and its employees are fully engaged in the execution of our business plan and are encouraged by our progress and achievements to date,” stated Benjamin S. Butcher, Chief Executive Officer of STAG.

·                  Declared a second quarter dividend of $0.26 per share (pro-rated to $0.2057 per share for the portion of the quarter the Company was public), which is an annualized rate of 8% on the $13 per share IPO price.

Financial Measures

Net operating income (NOI) is defined as rental revenues, including reimbursements, less property expenses and real estate taxes, which excludes depreciation, amortization, general and administrative expenses, interest expense, gain (loss) on interest rate swaps, asset management fee income, property acquisition costs and nonrecurring formation transaction costs. The Company considers NOI to be an appropriate supplemental performance measure because it reflects the operating performance of its properties and excludes certain items that are not considered to be controllable in connection with the management of the property.  However, this measure should not be viewed as an alternative measure of the Company’s financial performance since it excludes expenses which could materially impact the Company’s results of operations. Further, the Company’s NOI may not be comparable to that of other real estate companies, as they may use different methodologies for calculating NOI and cash NOI.

NAREIT developed FFO as a relative measure of performance of an equity REIT in order to recognize that the value of income-producing real estate historically has not depreciated on the basis determined under GAAP. FFO is generally defined as net income (loss) attributable to common stockholders, calculated in accordance with GAAP, plus real estate-related depreciation and amortization.  NAREIT’s definition of FFO is subject to interpretation, and modifications to the NAREIT definition of FFO are common.

The Company presents Core FFO excluding property acquisition costs and nonrecurring formation transaction costs, gain (loss) on interest rate swaps and amortization of above and below market leases.  The Company believes that Core FFO, excluding property acquisition costs, nonrecurring formation transaction costs, gain (loss) on interest rate swaps, and amortization of above and below market leases, is useful supplemental information regarding its operating performance as it provides a more meaningful and consistent comparison of the Company’s operating performance and allows investors to more easily compare the Company’s operating results.  Readers should note that FFO captures neither the changes in the value of the Company’s properties that result from use or market conditions, nor the level of capital expenditures and leasing commissions necessary to maintain the operating performance of the Company’s properties, all of which have real economic effect and could materially impact the Company’s results from operations. Accordingly, the Company’s Core FFO may not be comparable to other REITs’ FFO and FFO should be considered only as a supplement to net income (loss) attributable to common stockholders as a measure of the Company’s performance.

The Company believes that EBITDA is helpful to investors as a supplemental measure of the operating performance of a real estate company because it is a direct measure of the actual operating results of the Company’s industrial properties. The Company also uses this measure in ratios to compare its performance to that of its industry peers.  The Company presents EBITDA excluding property acquisition costs, nonrecurring formation transaction costs, gain (loss) on interest rate swaps and amortization of above and below market leases. The Company believes that EBITDA excluding property acquisition costs, nonrecurring formation transaction costs, gain (loss) on interest rate swaps and amortization of above and below market leases, is useful supplemental information regarding its operating performance as it provides a more meaningful and consistent comparison of the Company’s operating performance and allows investors to more easily compare the Company’s operating results.
