FORWARD-LOOKING STATEMENTS

The statements in this communication that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on current expectations, estimates and projections about the industry and markets in which Prologis and Duke Realty operate as well as beliefs and assumptions of Prologis and Duke Realty. Such statements involve uncertainties that could significantly impact Prologis’ or Duke Realty’s financial results. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” and “estimates,” including variations of such words and similar expressions, are intended to identify such forward-looking statements, which generally are not historical in nature. All statements that address operating performance, events or developments that Prologis or Duke Realty expects or anticipates will occur in the future — including statements relating to any possible transaction between Prologis and Duke Realty, rent and occupancy growth, acquisition and development activity, contribution and disposition activity, general conditions in the geographic areas where Prologis or Duke Realty operate, Prologis’ and Duke Realty’s respective debt, capital structure and financial position, Prologis’ and Duke Realty’s respective ability to earn revenues from co-investment ventures, form new co-investment ventures and the availability of capital in existing or new co-investment ventures — are forward-looking statements. These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict. Although Prologis and Duke Realty believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, neither Prologis nor Duke Realty can give assurance that its expectations will be attained and, therefore, actual outcomes and results may differ materially from what is expressed or forecasted in such forward-looking statements. Some of the factors that may affect outcomes and results include, but are not limited to: (i) Prologis’ and Duke Realty’s ability to complete the proposed transaction on the proposed terms or on the anticipated timeline, or at all, including risks and uncertainties related to securing the necessary shareholder approvals and satisfaction of other closing conditions to consummate the proposed transaction; (ii) the occurrence of any event, change or other circumstance that could give rise to the termination of the merger agreement relating to the proposed transaction; (iii) risks related to diverting the attention of Prologis and Duke Realty management from ongoing business operations; (iv) failure to realize the expected benefits of the proposed transaction; (v) significant transaction costs and/or unknown or inestimable liabilities; (vi) the risk of shareholder litigation in connection with the proposed transaction, including resulting expense or delay; (vii) the risk that Duke Realty’s business will not be integrated successfully or that such integration may be more difficult, time-consuming or costly than expected; (viii) risks related to future opportunities and plans for the combined company, including the uncertainty of expected future financial performance and results of the combined company following completion of the proposed transaction; (ix) the effect of the announcement of the proposed transaction on the ability of Prologis and Duke Realty to operate their respective businesses and retain and hire key personnel and to maintain favorable business relationships; (x) risks related to the market value of the Prologis common stock to be issued in the proposed transaction; (xi) other risks related to the completion of the proposed transaction and actions related thereto; (xii) national, international, regional and local economic and political climates and conditions; (xiii) changes in global financial markets, interest rates and foreign currency exchange rates; (xiv) increased or unanticipated competition for Prologis’ or Duke Realty’s properties; (xv) risks associated with acquisitions, dispositions and development of properties, including increased development costs due to additional regulatory requirements related to climate change; (xvi) maintenance of Real Estate Investment Trust status, tax structuring and changes in income tax laws and rates; (xvii) availability of financing and capital, the levels of debt that Prologis and Duke Realty maintain and their credit ratings; (xviii) risks related to Prologis’ and Duke Realty’s investments in co-investment ventures, including Prologis’ and Duke Realty’s ability to establish new co-investment ventures; (xix) risks of doing business internationally, including currency risks; (xx) environmental uncertainties, including risks of natural disasters; (xxi) risks related to the coronavirus pandemic; and (xxii) those additional factors discussed under Part I, Item 1A. Risk Factors in Prologis’ and Duke Realty’s respective Annual Reports on Form 10-K for the year ended December 31, 2021. Neither Prologis nor Duke Realty undertakes any duty to update any forward-looking statements appearing in this communication except as may be required by law.
