#### How do I vote?
For election of directors, you may either vote “For” the three nominees or you may “Withhold” your vote for all or for any nominee you specify. For any other matter to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:

#### For Shares Registered in Your Name
If your shares are registered in your name, you may vote using any of the following methods:

• To vote over the Internet prior to or during the Annual Meeting, follow the online instructions provided on the Notice.

• To vote by phone, call the toll-free number found on the proxy card, which you can request by following the instructions provided on the Notice.

• To vote by mail, follow the instructions provided on the Notice to request a proxy card and complete, sign and date the proxy card, and return it promptly by mail.

• Whether or not you plan to join the Annual Meeting, we strongly encourage you to vote by Internet or phone to ensure that your vote is timely received and counted. You may still vote by mail if you do not have access to the Internet or a phone. As long as we receive your signed proxy card, or your vote by Internet or phone, by 11:59 p.m. Eastern Daylight Time on May 7, 2025, we will vote your shares as you direct. Even if you have submitted a proxy or voted by phone or the Internet before the Annual Meeting, you may still join the Annual Meeting and vote online. In such case, your previously submitted proxy or vote will be disregarded.

For Shares Registered in the Name of a Broker, Bank or Other Agent

If you are a beneficial owner of shares registered in the name of your broker, bank or other agent, you should receive a voting instruction card and voting instructions with these proxy materials from that organization rather than from us. You should follow the instructions from your broker, bank or other agent included with these proxy materials, or contact your broker, bank or other agent to request a proxy card. You may also vote online at the Annual Meeting by following the voting instructions provided by your broker, bank or other agent to log in to www.virtualshareholdermeeting.com/CALX2025 and cast your vote. You should also complete and mail the voting instruction card to ensure that your vote is counted.
