Forward-Looking Statements

The Private Securities Litigation Reform Act of 1995 (the “1995 Act”) provides a “safe harbor” for forward-looking statements. This press release contains statements that are forward-looking, including statements relating to business and real estate development activities, future capital expenditures and financing sources. We intend such forward-looking statements to be covered by the safe-harbor provisions of the 1995 Act. The words “anticipate,” “believe,” “estimate,” “expect,” “intend,” “will,” “should” and similar expressions, as they relate to us, are intended to identify forward-looking statements. Although we believe that the expectations reflected in such forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be achieved. As forward-looking statements, these statements involve important risks, uncertainties and other factors that could cause actual results to differ materially from the expected results and, accordingly, such results may differ from those expressed in any forward-looking statements made by us or on our behalf. Factors that might cause actual results to differ materially from our expectations, many of which may be more likely to impact us as a result of the ongoing COVID-19 pandemic, are set forth in the “Risk Factors” section of our Annual Report on Form 10-K for the year ended December 31, 2021. Accordingly, we caution readers not to place undue reliance on forward-looking statements. We assume no obligation to update or supplement forward-looking statements that become untrue because of subsequent events.
