Forward-Looking Statements Some of the statements contained in this presentation constitute forward-looking statements within the meaning of the federal securities laws, including, but not limited to, statements regarding consummating asset sales and the timing thereof. Any forward-looking statements contained in this presentation are intended to be made pursuant to the safe harbor provisions of Section 21E of the Securities Exchange Act of 1934, as amended. Forward-looking statements relate to expectations, beliefs, projections, future plans and strategies, anticipated events or trends and similar expressions concerning matters that are not historical facts. In some cases, you can identify forward-looking statements by the use of forward-looking terminology such as “may,” “will,” “should,” “expects,” “intends,” “plans,” “anticipates,” “believes,” “estimates,” “predicts,” “potential,” or the negative of these words and phrases or similar words or phrases which are predictions of or indicate future events or trends and which do not relate solely to historical matters. You can also identify forward-looking statements by discussions of strategy, plans or intentions. The forward-looking statements contained in this presentation reflect the current views of Equity Commonwealth (NYSE: EQC) about future events and are subject to numerous known and unknown risks, uncertainties, assumptions and changes in circumstances regarding EQC and Monmouth Real Estate Investment Corporation (NYSE: MNR) that may cause EQC’s actual results to differ significantly from those expressed in any forward-looking statement, including, without limitation, (i) inability to complete the proposed merger because, among other reasons, one or more conditions to the closing of the proposed merger may not be satisfied or waived; (ii) uncertainty as to the timing of completion of the proposed merger; (iii) potential adverse effects or changes to relationships with EQC’s and/or MNR’s tenants, employees, service providers or other parties resulting from the announcement or completion of the proposed merger; (iv) the outcome of any legal proceedings that may be instituted against the parties and others related to the merger agreement; (v) possible disruptions from the proposed merger that could harm EQC’s or MNR’s respective business, including current plans and operations; (vi) unexpected costs, charges or expenses resulting from the proposed merger; (vii) uncertainty of the expected financial performance of EQC following completion of the proposed merger, including the possibility that the benefits anticipated from the proposed merger will not be realized or will not be realized within the expected time period; (viii) legislative, regulatory and economic developments; and (ix) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism, outbreak of war or hostilities and epidemics and pandemics, including COVID-19, as well as EQC’s or MNR’s management’s response to any of the aforementioned factors. EQC does not guarantee that the transactions and events described will happen as described (or that they will happen at all). While forward-looking statements reflect EQC’s good faith beliefs, they are not guarantees of future performance. EQC disclaims any obligation to publicly update or revise any forward-looking statement to reflect changes in underlying assumptions or factors, of new information, data or methods, future events or other changes. For a further discussion of these and other factors that could cause EQC’s future results to differ materially from any forward-looking statements, see the section entitled “Risk Factors” in EQC’s most recent Annual Report on Form 10-K and in EQC’s Quarterly Reports on Form 10-Q for subsequent quarters.No Offer or SolicitationThis presentation is not intended to and does not constitute an offer to sell or the solicitation of an offer to buy, sell or solicit any securities or any proxy, vote or approval in any jurisdiction pursuant to or in connection with the proposed transaction or otherwise, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
