Annual Meeting

CME Group Inc.
2020 Annual Meeting of Shareholders
Wednesday, May 6, 2020
10:00 a.m. CST

Due to public health concerns regarding the coronavirus (COVID-19) pandemic and governmental actions related thereto, including restrictions on in-person gatherings, we have determined to hold the Annual Meeting in a virtual meeting format only, with attendance via the Internet, to protect the health and well-being of our shareholders and our employees, management team and board of directors. You will not be able to attend the Annual Meeting in person.

RECORD DATE

You are entitled to vote if you were a Class A or Class B shareholder of CME Group as of the close of business on March 9, 2020 (the “record date”).

ACCESSING THE VIRTUAL MEETING
The Annual Meeting will be held virtually at www.virtualshareholdermeeting.com/CME2020. In order to attend the Annual Meeting virtually, you will need to log-in using the control number found on your proxy card, voting instruction form or notice that was previously mailed to you or sent to you electronically.  Online check-in will begin prior to the start of the Annual Meeting.  Guests without control numbers will be allowed to participate in the Annual Meeting in a listen only mode. 
 
We encourage you to submit your questions in advance of the meeting via officeofthesecretary@cmegroup.com.  Please include your name and the number of shares you own of CME Group as of the record date. In addition, you may submit questions and view the rules of conduct for the virtual Annual Meeting at www.virtualshareholdermeeting.com/CME2020. Please submit your questions once you gain access to the system.  We will follow up directly with any shareholders who submitted questions that were not answered due to time limitations.  
 

VOTING

Shareholders of record may vote during the Annual Meeting by following the instructions available on the meeting website.

The following is background on the timing that proxy materials, including control numbers, were distributed:
 

• The hardcopy Notices mailed Friday, March 27^th. 
• Class A emails and Class B-1 emails sent Wednesday, April 1^st.
• Class B-2 emails sent Wednesday, April 1^st.
• Class B-3 emails sent Thursday, April 2^nd.

Separate emails were sent out relating to each class of ownership and are linked to a shareholder’s SSN and email address.  Therefore, if a shareholder owns multiple classes of CME Group shares (i.e., Class A, Class B-1, etc.), the emails permit each class of shares to be voted separately.  There is a section that states “You have additional positions with CME Group Inc.”. 

If you believe you signed up for electronic distribution, please search your email, including any junk folders, for the email.  It would have been sent from CME GROUP INC. <id@proxyvote.com>. 

Given the current situation, we have set aside dedicated times to facilitate our Class B shareholder's requests for control numbers.  If a shareholder does not have their control number(s) and would like to vote, please contact Beth Hausoul (Shareholder Relations) at 630.696.6101 during the following times:
 

• Thursday, April 23: 2:00-4:00 p.m. CST
• Tuesday, April 28:  2:00-4:00 p.m. CST
• Thursday, April 30:  2:00-4:00 p.m. CST 

The purpose of these calls is to authenticate a shareholder’s identity and obtain an email for the distribution of the control number.  If your call goes to voicemail, please leave a message and your call will be returned as soon as possible.  Also, to ensure voter privacy, conversations with the shareholders to confirm their identity must be solely between Shareholder Relations and the individual.

Broadridge will send the control number(s) via email.  The subject line will read:  CME Group Control Number(s) for Annual Meeting on May 6, 2020.

Broadridge will respond on the following dates:

• Requests made on Thursday, April 23 will receive control numbers by Monday, April 27.
• Requests made on Tuesday, April 28 and Thursday, April 30 will receive control numbers by Monday, May 4.

As Broadridge is providing this enhanced service as a courtesy, please do not contact them directly. 

If you have any questions, please contact Beth Hausoul at elizabeth.hausoul@cmegroup.com or 630.696.6101. 

The foregoing is not a solicitation of your proxy which is made solely by way of the proxy materials.
