Item 5.07. Submission of Matters to a Vote of Security Holders.

On May 14, 2026, CME Group Inc. (the “Company”) held its 2026 Annual Meeting of Shareholders (the “Annual Meeting”). Due to lack of quorum among the Class B-1, Class B-2 and Class B-3 shareholders, the proposals presented under Items 4 through 8 were adjourned until June 9, 2026. These Items are described in further detail in the Company's definitive proxy statement on Schedule 14A filed with the SEC on March 23, 2026.

On June 9, 2026, the Company reconvened its Annual Meeting with regard to Items 4 through 8. At the close of business on March 16, 2026, the record date of the Annual Meeting, the Company had 362,808,081 shares of Class A and Class B common stock issued and outstanding. The following shares were present at the adjourned Annual Meeting, either in person or by proxy (total excludes broker non-votes):

Class(es) of Common Stock

Shares Issued and Outstanding

Aggregate No. of Shares Present

% of the Issued and Outstanding

Classes A and B

362,808,081 295,193,470 81.36 %

Class B-1

625 269 43.04 %

Class B-2

813 309 38.01 %

Class B-3

1,287 366 28.44 %

Class B-4

413 130 31.48 %

For each class of common stock voting separately on a proposal being presented at the Annual Meeting at least 33.3% of the class of common stock issued and outstanding must be present at the Annual Meeting to obtain quorum. Accordingly, the shares of Class B-3 common stock did not reach quorum and, therefore, Items 6 and 8c were not presented for approval to the Class B-3 shareholders.

The results of the proposals that were voted on at the adjourned Annual Meeting are as follows:

1.Item 4 - The proposal to eliminate the right of the Class B-1 shareholders to elect three directors did not pass. In order to pass, this Item required an affirmative vote from the holders of a majority of the outstanding shares of Class B-1 common stock voting as a single class and an affirmative vote from the holders of a majority of the outstanding shares of Class A and all Class B shareholders voting together as a single class.

Class(es) of Common Stock FOR FOR (%) AGAINST ABSTAIN

Class B-1 174 27.84 % 92 3

Classes A and B

291,250,517 80.27 % 2,439,875 1,503,078

2.Item 5 - The proposal to eliminate the right of the Class B-2 shareholders to elect two directors did not pass. In order to pass, this Item required an affirmative vote from the holders of a majority of the outstanding shares of Class B-2 common stock voting as a single class and an affirmative vote from the holders of a majority of the outstanding shares of Class A and all Class B shareholders voting together as a single class.

Class(es) of Common Stock FOR FOR (%) AGAINST ABSTAIN

Class B-2 190 23.37 % 115 4

Classes A and B

291,226,600 80.27 % 2,461,395 1,505,475

3.Item 6 - The proposal to eliminate the right of the Class B-3 shareholders to elect one director did not achieve quorum.

4.Item 7 - The proposal relating to an amendment to our certificate of incorporation passed; however, the amendment will not be filed, since its approval was contingent upon the approval of Items 4, 5 and 6. In order to pass, this Item required affirmative approval from the holders of a majority of the outstanding shares of Class A and Class B shareholders voting together as a single class.

Class(es) of Common Stock FOR FOR (%) AGAINST ABSTAIN

Classes A and B

291,324,525 80.29 % 2,267,873 1,601,072

5.Item 8 - Election of the Class B Directors:

a.Each of the Class B-1 directors have been re-elected to serve until the 2027 annual meeting of shareholders. For this Item, only Class B-1 shareholders vote.

Class B-1 Directors FOR AGAINST ABSTAIN

William H. Hobert (WH) 212 14 43

Patrick J. Mulchrone (PJM) 220 7 42

Robert J. Tierney Jr. (RJT) 219 8 42

b.The Class B-2 director has been re-elected to serve until the 2027 annual meeting of shareholders. For this Item, only Class B-2 shareholders vote.

Class B-2 Director FOR AGAINST ABSTAIN

Patrick W. Maloney (PAT) 238 14 57

c.In the election of one Class B-3 Director, no quorum was achieved. Therefore, Elizabeth A. Cook is a “holdover” under Delaware law and the Company’s bylaws. She will continue to serve until her successor is duly elected at the 2027 Annual Meeting or her earlier resignation.
