FOR THE 2020 ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD ON MAY 21, 2020

To the Stockholders of Belden Inc.,

Due to the public health impact of the coronavirus outbreak (COVID-19) and to support the health and well-being of our stockholders, directors, employees, and our community, the Company has changed the format of the 2020 Annual Meeting of Stockholders of Belden Inc. The Annual Meeting will be held over the Internet in a virtual meeting format only. You will not be able to attend the Annual Meeting in person. The date and time have not been changed, and the meeting will continue to be held on May 21, 2020 at 12:30 p.m., Central Time. Stockholders attending the Annual Meeting remotely will have the same opportunities they have had at past annual meetings to participate, vote, ask questions, and provide feedback to the company’s management team and the Board of Directors.

If you were a stockholder at the close of business on the record date of March 24, 2020, you are eligible to access, participate in and vote at the virtual meeting. The items of business are the same as set forth in the meeting notice previously mailed or made available to you.

The meeting will be hosted at https://www.virtualshareholdermeeting.com/BDC2020. The meeting will begin promptly at 12:30 p.m., Central Time and online access will open 15 minutes prior to allow time to log-in. You will need your voter control number, which you can find on your original proxy card, voting instruction form or Notice of Internet Availability of Proxy Materials.

You may continue to submit your proxy in advance of the Annual Meeting via the Internet, by phone or by mail by following the instructions included on the original proxy card, voting instruction form or notice previously distributed. Whether or not you plan to attend the Annual Meeting, we urge you to vote and submit your proxy in advance of the meeting using one of the methods described in the proxy materials. The proxy card included with the proxy materials previously distributed will not be updated to reflect the change in location and may continue to be used to vote your shares in connection with the Annual Meeting.
