On September 26, 2013, our chief executive officer and chairman of the board, Hamid R. Moghadam, adopted a pre-arranged 10b5-1 plan to exercise a portion of his vested stock options expiring in 2015 and sell the underlying shares received upon exercise of such options.

Mr. Moghadam is adopting such plan to exercise options that have near-term expiration dates in February 2015. This 10b5-1 plan was adopted in accordance with guidelines specified under Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, and our policies regarding stock transactions.

Options to purchase up to 142,718 shares of our common stock may be exercised under Mr. Moghadam’s 10b5-1 plan. All transactions under his 10b5-1 plan will be disclosed publicly in filings with the U.S. Securities and Exchange Commission.

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 operates, management’s beliefs and assumptions made by management. Such statements involve uncertainties that could significantly impact Prologis’ financial results. Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” 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 we expect or anticipate will occur in the future—including statements relating to rent and occupancy growth, development activity and changes in sales or contribution volume of properties, disposition activity, general conditions in the geographic areas where we operate, our debt and financial position, our ability to 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 we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our 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) national, international, regional and local economic climates, (ii) changes in financial markets, interest rates and foreign currency exchange rates, (iii) increased or unanticipated competition for our properties, (iv) risks associated with acquisitions, dispositions and development of properties, (v) maintenance of real estate investment trust (“REIT”) status and tax structuring, (vi) availability of financing and capital, the levels of debt that we maintain and our credit ratings, (vii) risks related to our investments in our co-investment ventures and funds, including our ability to establish new co-investment ventures and funds, (viii) risks of doing business internationally, including currency risks, (ix) environmental uncertainties, including risks of natural disasters, and (x) those additional factors discussed in reports filed with the Securities and Exchange Commission by Prologis under the heading “Risk Factors.” Prologis undertakes no duty to update any forward-looking statements appearing in this report.
