Cautionary Note Regarding Forward-Looking Statements

The statements in this report 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 management’s beliefs and assumptions. Such statements involve uncertainties that could significantly impact Prologis’ 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 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’ debt, capital structure and financial position, Prologis’ 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 believes the expectations reflected in any forward-looking statements are based on reasonable assumptions, Prologis can give no 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) the ultimate outcome of any possible transaction between Prologis and Duke Realty, including the possibility that Duke Realty will reject the proposed transaction with Prologis; (ii) uncertainties as to whether Duke Realty will cooperate with Prologis regarding the proposed transaction; (iii) 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; (iv) the timing of the proposed transaction; (v) the ability to satisfy closing conditions to the completion of the proposed transaction (including shareholder approvals); (vi) other risks related to the completion of the proposed transaction and actions related thereto; (vii) national, international, regional and local economic and political climates and conditions; (viii) changes in global financial markets, interest rates and foreign currency exchange rates; (ix) increased or unanticipated competition for Prologis’ or Duke Realty’s properties; (x) risks associated with acquisitions, dispositions and development of properties, including increased development costs due to additional regulatory requirements related to climate change; (xi) maintenance of Real Estate Investment Trust status, tax structuring and changes in income tax laws and rates; (xii) availability of financing and capital, the levels of debt that Prologis and Duke Realty maintain and their credit ratings; (xiii) risks related to Prologis’ investments in co-investment ventures, including Prologis’ ability to establish new co-investment ventures; (xiv) risks of doing business internationally, including currency risks; (xv) environmental uncertainties, including risks of natural disasters; (xvi) risks related to the coronavirus pandemic; and (xvii) 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. Prologis undertakes no duty to update any forward-looking statements appearing in this report except as may be required by law.
