Item 1.01 Entry into a Material Definitive Agreement.

On August 8, 2013, Prologis, Inc.’s (the “Company”) operating partnership Prologis, L.P. (the “Operating Partnership”) priced an offering of (i) $400,000,000 aggregate principal amount of its 2.750% notes due 2019 (the “2019 Notes”) and (ii) $850,000,000 aggregate principal amount of its 4.250% notes due 2023 (the “2023 Notes” and, together with the 2019 Notes, the “Notes”). In connection with the offering, the Company and the Operating Partnership entered into an Underwriting Agreement, dated August 8, 2013 (the “Underwriting Agreement”), with Citigroup Global Markets Inc., Goldman, Sachs & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and J.P. Morgan Securities LLC, as representatives 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 issuance and sale of the Notes is expected to close on August 15, 2013. 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 $1.24 billion. In the short term, the Operating Partnership intends to use the net proceeds from the sale of the Notes to repay borrowings under its global line and to fund the cash purchase of certain of its senior notes that are tendered pursuant to its offers to purchase such notes, which commenced on August 8, 2013. The Operating Partnership may also use the net proceeds to repay or repurchase other indebtedness and for general corporate purposes.

The 2019 Notes will bear interest at a rate of 2.750% per annum and mature on February 15, 2019. The 2023 Notes will bear interest at a rate of 4.250% per annum and mature on August 15, 2023. The Notes are senior unsecured obligations of the Operating Partnership and are 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 a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current treasury rate plus 20 basis points, in the case of the 2019 Notes, and basis 25 points, in the case of the 2023 Notes. Notwithstanding the foregoing, if the 2019 Notes are redeemed on or after January 15, 2019, or the 2023 Notes are redeemed on or after May 15, 2023, the redemption price will be 100% of the principal amount of the applicable series of Notes to be redeemed.

The Notes are being issued pursuant to the Registration Statement (File No. 333-177112) 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 August 8, 2013, and base prospectus, dated December 20, 2012, relating to the public offering of the Notes and corresponding guarantees, the Company and the Operating Partnership are filing the Underwriting Agreement 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.
