Item 1.01 Entry into a Material Definitive Agreement.

On October 1, 2014, Prologis, Inc.’s (the “Company”) operating partnership Prologis, L.P. (the “Operating Partnership”) priced an offering of €600,000,000 aggregate principal amount of its 1.375% Notes due 2020 (the “Notes”). In connection with the offering, the Company and the Operating Partnership entered into an Underwriting Agreement, dated October 1, 2014 (the “Underwriting Agreement”), with Goldman, Sachs & Co., J.P. Morgan Securities plc, Merrill Lynch International, Morgan Stanley & Co. International plc and The Royal Bank of Scotland plc, as lead managers of the several underwriters named in Schedule A thereto (the “Underwriters”), pursuant to which the Operating Partnership agreed to sell and the Underwriters agreed to purchase the Notes, subject to and upon the terms and conditions set forth therein. A copy of the Underwriting Agreement has been filed as an exhibit to this Current Report and is incorporated herein by reference.

The Notes are being issued under an indenture dated as of June 8, 2011 (the “Base Indenture”), among the Company, the Operating Partnership and U.S. Bank National Association, as trustee, as supplemented by the first supplemental indenture, dated as of June 8, 2011, the second supplemental indenture, dated as of June 8, 2011, the third supplemental indenture, dated as of June 8, 2011, the fourth supplemental indenture, dated as of June 8, 2011, the fifth supplemental indenture, dated as of August 15, 2013, the sixth supplemental indenture, dated as of December 3, 2013, and the seventh supplemental indenture, dated as of February 20, 2014 (the Base Indenture as supplemented by the first, second, third, fourth, fifth, sixth and seventh supplemental indentures, the “Indenture”).

The issuance and sale of the Notes is expected to close on October 7, 2014. The net proceeds to the Operating Partnership from the sale of the Notes, after the Underwriters’ discounts and offering expenses, are estimated to be approximately €596 million, or $751 million, based on the euro/U.S. dollar rate of exchange as of October 1, 2014. The Operating Partnership intends to use the net proceeds for general corporate purposes, including the acquisition and development of European properties and additional investments in its European co-investment ventures. In the short term, the Operating Partnership intends to use the net proceeds to repay borrowings under its global line of credit and/or its multi-currency senior term loan.

The Notes will bear interest at a rate of 1.375% per annum and mature on October 7, 2020. Interest on the Notes is payable annually in arrears on October 7 of each year, beginning on October 7, 2015. The Notes will be senior unsecured obligations of the Operating Partnership and will be fully and unconditionally guaranteed by the Company.

The Notes will be redeemable in whole at any time or in part from time to time, at the option of the Operating Partnership, at a redemption price equal to the greater of: (i) 100% of the principal amount of the Notes to be redeemed or (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed (exclusive of interest accrued to the date of redemption) discounted to the date of redemption on an annual basis (ACTUAL/ACTUAL (ICMA)) at the applicable comparable government bond rate plus 20 basis points. Notwithstanding the foregoing, if the Notes are redeemed on or after July 7, 2020, the redemption price will be 100% of the principal amount of the Notes to be redeemed.

The Indenture governing the Notes restricts, among other things, the Operating Partnership’s ability to incur additional indebtedness and to merge or consolidate with any other person or sell, assign, transfer, lease, convey or otherwise dispose of substantially all of its assets.

The Notes are being issued pursuant to the Registration Statement (File No. 333-195316) that the Company and the Operating Partnership filed with the Securities and Exchange Commission (the “SEC”) relating to the public offering from time to time of securities of the Company and the Operating Partnership pursuant to Rule 415 of the Securities Act of 1933, as amended. In connection with filing with the SEC a definitive prospectus supplement, dated October 1, 2014, and base prospectus, dated April 16, 2014, relating to the public offering of the Notes and corresponding guarantees, the Company and the Operating Partnership are filing the Underwriting Agreement, the form of the Notes and certain other exhibits with this Current Report of Form 8-K as an exhibit to such Registration Statement. See “Item 9.01 – Financial Statements and Exhibits.”

This Current Report does not constitute an offer to sell, or a solicitation of an offer to buy, any security and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offer, solicitation or sale would be unlawful.
