(2) Cost includes purchase price plus property acquisition costs

Subsequent to year-end, and through February 23, 2015, the Company acquired one industrial building consisting of 503,490 square feet for $34.3 million and was funded by using cash on hand and granting 812,676 Common Units in the Operating Partnership (“OP Units”) with a fair value of $21.9 million. This building was under contract as of December 31, 2014.  As of February 23, 2015, the Company had entered into contracts to acquire seven industrial buildings for $93.8 million. Included in the acquisitions under contract are three build-to-suit transactions, which are scheduled to close in the second quarter of 2015. The Company also executed non-binding letters of intent (“LOI”) to acquire six additional industrial buildings for $39.4 million.

As of February 23, 2015, the Company’s pipeline of potential acquisitions is $1.2 billion and 94 industrial buildings.  The pipeline is a point in time measure that includes all of the transactions under consideration

by the Company’s acquisitions group that have passed the initial screening process.  The pipeline also includes transactions under contract and transactions with non-binding LOIs.

Inclusive of contracts executed but not yet closed, the Company has closed or committed to close a total of $128.1 million of acquisitions year-to-date.  In 2015, consistent with past years, the Company will target 25% growth in its portfolio, equating to approximately $450 million of acquisitions.

The purchase and sale agreements for the properties under contract are subject to satisfaction of closing conditions, and the properties under LOI require the negotiation and execution of definitive purchase and sale agreements.  There can be no assurance that any of the properties under contract or LOI will be acquired on the terms anticipated or at all.  In addition, there can be no assurance that the Company will achieve its targeted acquisition level for 2015.

During the year ended December 31, 2014, the Company sold four industrial buildings consisting of 433,153 square feet for $13.5 million. The chart below reflects the disposition activity during the year ended December 31, 2014:

As a high growth company, the Company’s same store Cash NOI is impacted by the material annual additions to the “same store” portfolio, averaging 41% per annum on a real estate cost basis since the Company’s initial public offering in 2011.  Furthermore, to date, the Company has generally acquired buildings that are approximately 100% occupied, while the broader market, which ultimately governs the Company’s occupancy, is between 90% and 95% occupied.  Therefore, the Company’s same store Cash NOI performance is not representative of the true performance of the portfolio.  So long as the Company acquires buildings at a material pace with occupancy levels above market, management believes this dynamic (normalization of occupancy) will continue to exist and will tend to dampen our “same store” performance (see the Company’s supplemental information package for additional disclosure).  Operationally, the Company’s asset management team focuses on retention rates, de novo leasing

activity, rental rate achievement, and other property level revenue and expense items. All of these measures are disclosed in our supplemental information package.

Key Financial Measures

Cash NOI and Core FFO for the year were $142.4 million and $84.2 million, respectively.  Cash NOI and Core FFO for the three months ended December 31, 2014 were $41.4 million and $23.9 million, respectively.  The Company believes that Cash NOI and Core FFO are useful supplemental measures of the Company’s operating performance as they provide a more meaningful and consistent comparison of the Company’s operating performance and allow investors to more easily compare the Company’s operating results.

The Company continued its accretive growth of recurring operating income during the year, with Core FFO growing 24% as compared to the year ended 2013 and 6% on a diluted, per share basis.  Cash NOI also grew 24% over the same period.  For the three months ended December 31, 2014, Core FFO grew 26% as compared to the three months ended December 31, 2013 in the aggregate and remained flat on a diluted, per share basis.  Cash NOI grew 24% over the same time period.  Core FFO and Cash NOI do not include a full quarter’s income associated with buildings acquired during the quarter.  Inclusive of this income and exculsive of termination fee income, run rate Cash NOI would have been $40.0 million for the three months ended December 31, 2014.

Net loss for the three months ended December 31, 2014 was $2.6 million. Included in net loss is depreciation and amortization expense of $25.5 million.  A reconciliation of net income (loss) to Cash NOI, adjusted earnings before interest, tax, depreciation and amortization (“Adjusted EBITDA”), Core FFO, FFO, and adjusted FFO (“AFFO”), all non-GAAP financial measures, appears at the end of this release (see the Company’s supplemental information package for additional disclosure).

The Company’s key financial measures are noted in the chart below:

KEY FINANCIAL MEASURES

General and administrative expenses for the three months ended December 31, 2014 were $6.9 million.  This included a non-recurring, non-cash compensation expense of $929,000 related to the early departure of an officer.  Excluding this non-recurring expense, general and administrative expenses for the quarter were $6.0 million.  The Company estimates that general and administrative expenses will be approximately $30 million for 2015.  The Company has a long term goal of having general and administrative expenses at approximately 10% of Cash NOI.  As a growth company, the Company’s expense levels are the result of developing a platform to confidently address not only the recent opportunities and challenges but also future opportunities and challenges management foresees.

On December 22, 2014, the Company completed the following refinancing and modification of the unsecured credit facility and unsecured term loans:
