Since the announcement of the Merger, the Company and the Operating Partnership have received requests for additional information regarding the effect of the Merger on the holders of the Partnership Common Units, the Partnership Preferred Units, the Partnership LTIP Units and the Class I High Performance Units (collectively, the “~~Unitholders~~Merger”). In response, the Company and the Partnership prepared a letter to the Unitholders addressing such questions. A copy of the letter is attached hereto as Exhibit 99.1 and is incorporated herein by reference.

~~8-K~~In light of the Merger Agreement, on April 30, 2024, the board of directors of the Company cancelled the Company’s 2024 annual meeting of stockholders previously scheduled for June 14, 2024. Instead, the Company expects to hold a special meeting of its stockholders to vote upon the approval of the Merger on a date that will be publicly announced. The Company expects that the current members of its board of directors will continue as directors until the completion of the Merger.

If the Merger Agreement is terminated for any reason, the Company expects it will hold an annual meeting of stockholders in 2024.

Cautionary Statement Regarding Forward-Looking Statements

This communication includes certain disclosures which contain “forward-looking statements” within the meaning of the federal securities laws, including but not limited to those statements related to the Merger, including financial estimates and statements as to the expected timing, completion and effects of the Merger. You can identify forward-looking statements because they contain words such as “expect,” “believe,” “target,” “project,” “goals,” “estimate,” “potential,” “predict,” “may,” “will,” “might,” “could,” “forecast,” “outlook” and variations of these terms or the negative of these terms and similar expressions. Forward-looking statements, including statements regarding the Merger, are based on the Company’s current expectations and assumptions. Because forward-looking statements relate to the future, they are subject to inherent uncertainties, risks and changes in circumstances that may differ materially from those contemplated by the forward-looking statements, which are neither statements of historical fact nor guarantees or assurances of future performance.

Important factors, risks and uncertainties that could cause actual results to differ materially from such plans, estimates or expectations include but are not limited to: (i) our ability to complete the Merger on the anticipated terms and timing, or at all, including our ability to obtain the required stockholder approval, and our ability to satisfy the other conditions to the completion of the Merger; (ii) potential litigation relating to the Merger that could be instituted against the Company or its directors, managers or officers, including the effects of any outcomes related thereto; (iii) the risk that disruptions from the Merger will harm the Company’s business, including current plans and operations, including during the pendency of the Merger; (iv) the ability of the Company to retain and hire key personnel; (v) potential adverse reactions or changes to business relationships resulting from the announcement or completion of the Merger; (vi) legislative, regulatory and economic developments; (vii) potential business uncertainty, including changes to existing business relationships, during the pendency of the Merger that could affect the Company’s financial performance; (viii) certain restrictions during the pendency of the Merger that may impact the Company’s ability to pursue certain business opportunities or strategic transactions; (ix) unpredictability and severity of catastrophic events, including but not limited to acts of terrorism, outbreaks of war or hostilities or the COVID-19 pandemic, as well as management’s response to any of the aforementioned factors; (x) the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (xi) the occurrence of any event, change or other circumstance that could give rise to the termination of the Merger, including in circumstances requiring the Company to pay a termination fee; (xii) those risks and uncertainties set forth under the headings “Special Note Regarding Forward Looking Statements” and “Risk Factors” in the Company’s most recent Annual Report on Form 10-K, as such risk factors may be amended, supplemented or superseded from time to time by other reports filed by the Company with the Securities and Exchange Commission (the “SEC”) from time to time, which are available via the SEC’s website at www.sec.gov; and (xiii) those risks that will be described in the proxy statement that will be filed with the SEC and available from the sources indicated below.

10-K,

SEC

These risks, as well as other risks associated with the Merger, will be more fully discussed in the proxy statement that will be filed with the SEC in connection with the Merger. There can be no assurance that the Merger will be completed, or if it is completed, that it will close within the anticipated time period. These factors should not be construed as exhaustive and should be read in conjunction with the other forward-looking statements. The forward-looking statements relate only to events as of the date on which the statements are made. The Company does not undertake any obligation to publicly update or review any forward-looking statement except as required by law, whether as a result of new information, future developments or otherwise. If one or more of these or other risks or uncertainties materialize, or if our underlying assumptions prove to be incorrect, our actual results may vary materially from what we may have expressed or implied by these forward-looking statements. We caution that you should not place undue reliance on any of our forward-looking statements. You should specifically consider the factors identified in this communication that could cause actual results to differ. Furthermore, new risks and uncertainties arise from time to time, and it is impossible for us to predict those events or how they may affect the Company.
