2 FORWARD-LOOKING STATEMENTS Certain statements contained in this presentation other than historical facts may be considered forward-looking statements. Such statements include, in particular, statements about our plans, strategies, and prospects, and are subject to certain risks and uncertainties, including known and unknown risks, which could cause actual results to differ materially from those projected or anticipated. Therefore, such statements are not intended to be a guarantee of our performance in future periods. Such forward-looking statements can generally be identified by our use of forward-looking terminology such as "may," "will," "expect," "intend," "anticipate," "estimate," "believe," "continue," or other similar words. These forward-looking statements include information about possible or assumed future results of the business and our financial condition, liquidity, results of operations, future plans and objectives. They also include, among other things, statement regarding subjects that are forward-looking by their nature, such as our business and financial strategy, our 2018 guidance (including projected net operating income, cash rents and contractual growth), projected yield and earnings growth compared to peers, our ability to obtain future financing, future acquisitions and dispositions of operating assets, future repurchases of common stock, and market and industry trends. Readers are cautioned not to place undue reliance on these forward-looking statements. We make no representations or warranties (express or implied) about the accuracy of any such forward-looking statements contained in this presentation, and we do not intend to publicly update or revise any forward-looking statements, whether as a result of new information, future events, or otherwise. Any such forward-looking statements are subject to risks, uncertainties, and other factors and are based on a number of assumptions involving judgments with respect to, among other things, future economic, competitive, and market conditions, all of which are difficult or impossible to predict accurately. To the extent that our assumptions differ from actual conditions, our ability to accurately anticipate results expressed in such forward- looking statements, including our ability to generate positive cash flow from operations, make distributions to stockholders, and maintain the value of our real estate properties, may be significantly hindered. See Item 1A in the Company's most recently filed Annual Report on Form 10-K for the year ended December 31, 2017, for a discussion of some of the risks and uncertainties that could cause actual results to differ materially from those presented in our forward-looking statements. The risk factors described in our Annual Report are not the only ones we face but do represent those risks and uncertainties that we believe are material to us. Additional risks and uncertainties not currently known to us or that we currently deem immaterial may also harm our business. For additional information, please reference the supplemental report furnished by the Company as Exhibit 99.1 to the Company’s Form 8-K furnished to the Securities and Exchange Commission on February 15, 2018.
