Re: Mondelēz International, Inc.

Registration Statement on FormS-3 (FileNo. 333-236787)

Ladies and Gentlemen:

We have acted as counsel to Mondelēz International, Inc., a Virginia corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) of a prospectus supplement, dated June 30, 2020 (the “Prospectus Supplement”), filed with the Commission on July 1, 2020 pursuant to Rule 424(b) of the Securities Act of 1933, as amended (the “Securities Act”), and the offering by the Company pursuant thereto of $1,000,000,000 principal amount of the Company’s 0.625% Notes due 2022 (the “Notes”). In connection with the offering of the Notes, we have examined the registration statement on FormS-3, FileNo. 333-236787 (the “Registration Statement”), under the Securities Act and the prospectus included therein.

The Notes have been issued pursuant to the Indenture, dated as of March 6, 2015 (the “Base Indenture”), between the Company and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”), as modified by the Supplemental Indenture No. 1, dated as of February 13, 2019, between the Company and the Trustee and the Supplemental Indenture No. 2, dated as of April 13, 2020, between the Company and the Trustee, and as further modified in respect of the Notes by the Officers’ Certificate pursuant to Sections 201 and 301 of the Base Indenture, dated as of the date hereof (the Base Indenture, as so modified, the “Indenture”).

In arriving at the opinions expressed below, we have examined originals, or copies certified or otherwise identified to our satisfaction as being true and complete copies of the originals, of the Indenture and the Notes and such other documents, corporate records, certificates of officers of the Company and of public officials and other instruments as we have deemed necessary or advisable to enable us to render these opinions. In our examination, we have assumed, without independent investigation, the genuineness of all signatures, the legal capacity and competency of all natural persons, the authenticity of all documents submitted to us as originals and the conformity to original documents of all documents submitted to us as copies. As to any facts material to these opinions, we have relied to the extent we deemed appropriate and without independent investigation upon statements and representations of officers and other representatives of the Company and others.

Based upon the foregoing, and subject to the assumptions, exceptions, qualifications and limitations set forth herein, we are of the opinion that the Notes are legal, valid and binding obligations of the Company, enforceable against the Company in accordance with their respective terms.
