 your shares may be voted by your broker in its discretion on Proposal 2.

If you are a beneficial owner of shares held in street name, and you do not plan to attend the Annual Meeting, in order to ensure your shares are voted in the way you would prefer, you mustprovide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent.**

What are “broker non-votes”? As discussed above, when a beneficial owner of shares held in street name does not give voting instructions to his or her broker, bank or other securities intermediary holding his or her shares as to how to vote on matters deemed to be “non-routine,”the broker, bank or other such agent cannot vote the shares. When there is at least one “routine” matter that the broker, bank or other securities intermediary votes on, the shares that are un-votedon “non-routine”matters are counted as “broker non-votes.”Proposal 2 is a “routine” matter and we therefore expect brokers, banks or other securities intermediaries to vote on that proposal. Proposals 1 and 3 are considered to be “non-routine”and we therefore expect broker non-votesto exist in connection with those proposals. As a reminder, if you are a beneficial owner of shares held in street name, in order to ensure your shares are voted in the way you would prefer, you mustprovide voting instructions to your broker, bank or other agent by the deadline provided in the materials you receive from your broker, bank or other agent. What does it mean if I receive more than one Notice? If you receive more than one Notice, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the Notices to ensure that all of your shares are voted. Can I change my vote after submitting my proxy? Stockholder of Record: Shares Registered in Your Name Yes. You can revoke your proxy at any time before the final vote at the Annual Meeting. If you are the record holder of your shares, you may revoke your proxy in any one of the following ways:

| • |     | You may submit another properly completed proxy card with a later date. |

| • |     | You may grant a subsequent proxy by telephone or through the internet. |

| • |     | You may send a timely written notice that you are revoking your proxy to Tempus’s Secretary
