DISCLAIMER CAUTIONARY STATEMENTS CONCERNING FORWARD-LOOKING STATEMENTS Various statements contained in this presentation, including those that express a belief, expectation or intention, as well as those that are not statements of historical fact, are forward-looking statements. Forward-looking statements are generally accompanied by words such as “estimate,” project,” “predict,” “believe,” “expect,” “anticipate,” “potential,” “plan,” “goal” or other words that convey the uncertainty of future events or outcomes. Forward-looking statements in this presentation include, for example, references to the expected increase in the Company’s revolving credit facility and references to the Company’s pipeline of potential acquisitions, as to which there can be no assurance of completion. The forward-looking statements speak only as of the date of this presentation; The Company disclaims any obligation to update these statements unless required by law, and the Company cautions you not to rely on them unduly. The Company has based these forward-looking statements on its current expectations and assumptions about future events, which the Company considers reasonable. However, these forward-looking statements are inherently subject to significant business, economic, competitive, regulatory and other risks, contingencies and uncertainties, most of which are difficult to predict and beyond the Company's control. NON-GAAP FINANCIAL INFORMATION This presentation contains non-generally accepted accounting principles (GAAP) financial measures including, funds from operations (“FFO”), adjusted funds from operations (“AFFO”), earnings before interest, taxes, depreciation and amortization (“EBITDA”), EBITDA further adjusted to exclude gains (losses) on sales of depreciable property and real estate impairment losses (“EBITDAre”), Adjusted EBITDAre, Annualized Adjusted EBITDAre and Net Debt. The Company believes these non-GAAP financial measures are industry measures used by analysts and investors to compare the operating performance of REITs. However, such measures should not be considered in isolation or as an indicator of the Company's performance. Furthermore, they should not be seen as a substitute for metrics prepared in accordance with GAAP. Reconciliations of these measures to their most directly comparable GAAP measures for the periods that are presented in this presentation can be found in the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations – Non-GAAP Measures” in the Company’s Quarterly Report on Form 10-Q, which was filed with the SEC on November 5, 2020.
