Ladies and Gentlemen:

We have acted as special counsel to Prologis, Inc., a Maryland corporation (the “Parent”), and its operating partnership, Prologis, L.P., a Delaware limited partnership (the “Issuer”), in connection with the registration under the Securities Act of 1933, as amended (the “Securities Act”), of $800,000,000 aggregate principal amount of the Issuer’s 5.000% Notes due 2034 (the “2034 Notes”) and $450,000,000 aggregate principal amount of the Issuer’s 5.250% Notes due 2054 (the “2054 Notes” and, together with the 2034 Notes, the “Notes”), as described in the prospectus relating to the Notes (the “Prospectus”), as supplemented by the prospectus supplement, dated as of January 18, 2024 (the “Prospectus Supplement”), contained in the Issuer’s and the Parent’s Registration Statement on Form S-3 (File No. 333-267431) (the “Registration Statement”). The Notes will be issued under the Indenture, dated as of June 8, 2011 (the “Base Indenture”), among the Issuer and the Parent and U.S. Bank Trust Company, National Association, as successor in interest to U.S. Bank National Association, as trustee (the “Trustee”), as supplemented by the fifth supplemental indenture, dated as of August 15, 2013 (the Base Indenture as supplemented by the fifth supplemental indenture, the “Indenture”).

We have also participated in the preparation and filing with the Securities and Exchange Commission (the “SEC”) under the Securities Act of the Registration Statement, relating to the debt securities of which the Notes are a part. In rendering our opinions set forth below, we have examined originals or copies identified to our satisfaction of (i) the Registration Statement, including the Prospectus; (ii) the Prospectus Supplement; (iii) the Parent’s Articles of Incorporation, as amended and supplemented; (iv) the Parent’s Ninth Amended and Restated Bylaws; (v) the certificate of limited partnership of the Issuer; (vi) the Thirteenth Amended and Restated Agreement of Limited Partnership, as amended, of the Issuer; (vii) resolutions of the Parent’s Board of Directors and committees thereof; (viii) the Indenture and (ix) the forms of the Notes. In addition, we have examined and relied upon other documents, certificates, corporate records, opinions and instruments, obtained from the Issuer and the Parent or other sources believed by us to be reliable, as we have deemed necessary or appropriate for the purpose of this opinion. In rendering this opinion, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals and the conformity to authentic original documents of all documents submitted to us as copies.

Based upon and subject to the foregoing and to the assumptions, conditions and limitations set forth herein, we are of the opinion that the Notes have been duly authorized and, when executed by the Issuer and authenticated by the Trustee in the manner provided for in the Indenture and delivered against payment therefore, will constitute valid and binding obligations of the Issuer, enforceable in accordance with their terms, except as (a) the enforcement thereof may be limited by bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or other similar laws relating to or affecting the rights and remedies of creditors or by general equitable principles and (b) the enforceability of provisions imposing liquidated damages, penalties or an increase in interest rate upon the occurrence of certain events may be limited in certain circumstances, and will be entitled to the benefits of the Indenture.
